[INFO] Battery life, what is causing a constant trickle of power usage - HTC One X

Hi
Some have good battery life, others say it drains away by itself in a matter of hours. I've been experiencing a several percent battery drain an hour when the phone is just idle so did some digging.
Exchange Active Sync on push
Exchange Active Sync on push can go from being very efficient, i.e more so than frequent polling, to being a big battery drain.
Because of the way EAS works on push, the phone is woken every 15 minutes to check and renew the link to the server. If the network or service provider has a low time-out on idle connections, say 5 minutes, the phone eventually works out it needs to wake and renew the link every 5 minutes. If the network time-out is very low say a minute, the phone is being woken 60 times an hour to renew the link. Because the wake cycle is very quick, it doesn't show in the battery chart as a blue line wake event, so this awakening is hidden, however all that waking up takes it toll on the battery, plus the radio has to go from low power states up to full to pass data and open a new link, so over the course of a day, EAS can be using a significant amount of power.
Also as this wake cycle is dynamic based on the network it is going to vary for everyone, and any configuration changes unknown to us on the network could suddenly see the phone battery life making a big improvement or getting worse and no two people will have the same experience of EAS on push.
If you find the phone is losing several percent an hour even when sat being unused, and you are using EAS on push, try disabling it or moving to a timed polled. If you just have to get your emails immediately, you may just have to take the hit.
HTC Weather Widgets
I think I have found an odd thing about HTC Weather Widgets, they are not all the same when we are asking them to show our current location. Some HTC weather widgets use HTC's own server to decide the current location based on the cell tower, other HTC weather widgets use Google Maps API to fetch the current location. When using Google Maps, it uses more CPU power, and means Google Maps is activated quite often by some weather widgets where it then starts using Wi-Fi and often GPS (it uses GPS to get a good location then sends that location back to Google's servers with a list of nearby Wi-Fi points to build its Wi-Fi location database). If you see Maps using several percent in the battery usage list along with some GPS seconds and you haven't actually used the Maps application, this is probably the reason.
The easiest way to tell which HTC Weather Widgets are using Google services and so draining more power is to go to Settings -> Location and disable Google location services. Now the widgets using the Google Maps API will show a message telling us to enable Google Location services, other HTC weather widgets carry on working showing the current location. I found the large full page weather widget, and the lock screen weather wallpaper carries on working showing the current location without needing Google Location, but the weather/clock widget, set by default on the home page, is using Google Location.
I've since set the weather clock to my fixed home location, keeping the lock screen weather and large weather widget on current location, and 12 hours in, even with Google location services enabled, Google Maps has yet to show up in the battery usage list at it's usual several percent, prior to this change, the Maps app, even though I've gone days without using it, has constantly shown in the battery usage list.
So since putting EAS onto manual, and setting the clock weather widget to a fixed location, my phone can sit happily for a couple of hours, still connected to the network for phone calls and texts and ready for me to pick up and use, but doesn't report losing any power. This means when I do want to use it, I have more power left for on-screen time.
There are probably many more innocent widgets or settings we can change that can cause a knock-on effect to battery life that we don't quite expect. It also means no two people, once they've played and customised the phone to their liking, will have the same experience with battery life.
I also suspect a big part of custom ROMs having better battery life is simply down to the often stripped away back to basics nature of them, by default HTC Sense is using a couple of percent an hour just on the clock/weather widget to show us our general current location. Over a day that adds up to a lot of power just to see on your phone what you can see looking out of the window.
Hope the above helps someone.
Regards
Phil

Battery Life

I have a widget that shows me how much I have left and when I unplug it after a full charge, I have 6 hours left.
Ridiculous.
This is on auto brightness, wifi, twitter/facebook/mail updating every 15 minutes.
whenever I take my phone out the house I have to bring a charger...
bloody ridiculous.
couple of points.
1) When you leave the house, don't leave your wi-fi on! I find wi-fi to be the biggest battery drain out of everything ( expect gps)
2) I use a brightness widget, therefore when your in doors you can have it on low, then when your out doors have it on high, i assume this will use less battery then auto brightness
3) why do you need facebook updating every 15 minutes?? Do you honestly look at your phone that much when your out? change the settings so it updates every 15 when your on wi-fi at home, and every hour for when your not.
Wifi isn't an issue. I leave it on 24/7 as well as bluetooth and still can get 36 hours out od a charge. Its hooked up to wifi 20hrs a day as well.

1. Battery and other constantly updating widgets are one of the causes for battery drain. Get rid of it.
2. Battery widgets try to get an estimate of your typical use. They are mostly wrong in my opinion
3. I can get 6 hours of battery, yes, but only if glue the phone to my hand and use it constantly for that time
4. there are tons of battery threads around, use those suggestions (mid brightness, no live wallpaper, turn airplane on when you know coverage will be unavailable for long, etc)
5. Battery gets better in 10 days.
6. Most people can get at the very least one day of heavy usage. If you really need to hammer the battery get a spare one, they are cheap. Oh, and realize you are lucky because you CAN have a spare battery !
7. If you are using an automatic task killer, get rid of it.

1) go to the market and search brightness level, or brightness widget, there are a number of these. The best i find is brightness level by curvefish, it lets you pick a percentage and keep at that .
2) Cant remeber actually where the settings are but there is a way. But i prefer to use another widget, autosync on/off, this allows you to update every 15 when on wi-fi, but when you want to save battery, turn auto sync off and it doesnt sync ,
I suggest you use switchpro widget. its like the power control widget but with more options to turn on/off things.
I typically charged my Nokia N97 every other day or so, even though I used it frequently, and needless to say the HTC Desire doesn't have the same stamina. I was quite frustrated by it, and I started thinking of ways to save power. I came up with 19 tips, and I have actually noticed quite a difference by following them
19 Tips to Keep the HTC Desire Running a Little Longer
Nice post thanks.ill give this a go. But I have a question to do with the positioning using data or gps. I believe your stating that you should turn data off for this purpose, and let the gps do it? however my phone was set to opposite. when I changed as you were suggesting and I clicked allow gps, I had a message come up saying to turn off to conserve battery? But your saying to turn on? And have data off? Also how do you get into htc facebook settings,i cant even find it!

yep i also use this widget
also use a free juice defender or paid ultimate juice that keeps turning on and off your 3g every now and then depending on how you schedule it, my phone with snowstorm weather widget updating every 80 minutes + 30s of 3g every 5 minutes to update mail etc and average usage lasts about 36 hours which is good enough for me
I leave my WI-FI on at home and suffer hardly any drain.
At work like today leave my Mobile network on down to 47% with just twitter usage!
Pathetic is the mobile signals drain.

Ok, ive had another read of this and am now just even more confused! Are you saying to have gps turned off via settings and location aswell as data, or just having gps on? Are you saying that having gps selected via settings for the purpose of locating services uses les batty than via using data? Either way, it appeatss that the power control widget controls the gps the same as via settings. Right now ive deselected gps and the data location.

I believe this is what I'm saying:
"To let your device learn your location via wireless network triangulation requires less battery than by using the GPS for this purpose. However, using both methods simultaneously is probably not a good idea from a battery point of view. The GPS can handle this task by itself, although it will get a fix on your location a little bit slower. Also, wireless network positioning will be used to collect anonymous Google location data, which will drain the battery further. You can change this option from Settings > Location > Use wireless networks. "
In other words, to only use wireless network positioning will supposedly use less battery than by only using the GPS, but using both methods will naturally use the most juice
For me...
- Turn GPS On when I needed.
- Turn WiFi On when I needed
- Turn Bluetooth On when I needed
- Use 2G Network for standard internet, we use 3G if we want more speed such us watch video

I can get get good days heavy usage (except games) from mine, I haven't tried the 2G thing yet.
Apparently it is the connectivity thing that kills the battery, but turning off 3G, doesn't that take all the fun out of it???
If you just use it as a phone then I reckon you can get a couple of days out of it, or so I've read...

Battery Issues, Uptime = Awake, Google Calendar

Hi,
I am having severe problems with battery life where Uptime is equal to Awake or at least very very close to it. I kill Calendar (calendar.bg process) each time after starting the phone, and still I suffer from problems. Today my battery died from 100 to 25 in 7 hours, and I removed both Flickr and killed Google Calendar Sync process again. I've noticed that too many times Google Calendar sync icon in the Google Content Provider window is turning around while there aren't any changes of Google Calendars I've made.
Is it possible and a good solution overall to turn off syncing Calendar via Google content provider and instead configure a Exchange with Google Sync?
I am not sure about calender killing but I just use juicydefender and thgat has massively improved my battery life to over double the time..... might be worth trying that....
I use JuiceDefender as well (UltimateJuice edition) but despite that my phone has died today, so far it is around 9% and I have absolutely no idea why it's dying so fast.
I think I must have some application that prohibits my phone from going into sleep mode. I turned off Flickr completely (I use PicPush to push photos online), I just removed Fring and eBuddy from my phone (I think the culpit may be eBuddy but not really sure). I use Executive Assistant although without Twitter/Facebook pulls.
My Twitter pull is 2 hours. My Facebook pull is 4 hours. I use both internal Sense Peeps and external Twitter for Android content providers because I like to have Peep tweets into my Contact List, althought I am looking for feedback if this is eating too much battery.
Anyway the major sync problem is the Calendar. IT'S TAKING AGES AND ALMOST EVERY TIME I GO TO SYNC WHEN PHONE IS SYNCING, IT'S CALENDAR THAT ROLLS ITS PROGRESS ICON TO NO END. I have no idea why HTC is doing this travesty with its phones, and absolutely no idea how to make Calendar behave on my phone.
Anyway, I ordered MUGEN 3200 MAh battery as a long-term solution. 7mm on the phone's width won't be the best thing to have but it is something I'll get used to if I want to have a phone that lives through a day even if used.
WHAT THE HELL!?
I have turned off Google Calendar sync, and configured Google Sync as Exchange for Calendar events only. Despite the fact, I've noticed the turning circle of sync progress in front of Google Calendar sync (in Google Account) even if it is unchecked. I am totally lost now, what can I do to resolve this?
My next Android may not be HTC.
Hmm - I had exactly the same problem, 'Calendar' using up most of the partial wake. However I'm not convinced it is really the Google Calendar itself causing the problem. I've still got the Agenda widget installed but switched off syncing for the 'Stock' app (as I never use it anyway) and also deleted my Flickr account from the phone - even after a few reboots that still seems to have done the trick and the Calendar partial wake is now miniscule and battery life has shot up.
Do you want to try removing your Flickr account completely and see if that helps?
I've already raised a ticket with HTC about this (and a few other issues). They weren't that helpful when I first emailed them, they've been much better since I phoned them and asked for it to be escalated to a level 2 agent. I'm now getting pretty much daily updates from their agent. They asked me to remove the Agenda widget to see if it helped but now I don't have the problem it's difficult to try these things out - I'm sure they'd be happy to work with you. After you've logged the issue then feel free to PM your email +/- ticket number and I can update my ticket to ask them to run through the troubleshooting with you too.
I have the same issue with my Desire, I don't know how the battery life can be this bad to be honest , but from what I have heard from the latest update the battery life has been really bad for a lot of people, but some others have been lucky.
I have emailed HTC, so lets see what they have to say. Looks like we may have to wait for the next software update so they can resolve this issue.
Other than that I love my Desire and am extremely happy with it

Meanwhile I did this:
I did a factory reset of the phone today, and reinstalled some of the apps I really use and none of those I just kept for rare occasions. I cut down apps that have processes as well.
I turned off Internet Time as I saw online it improved battery time. I don't sync Stocks. I do sync Weather however.
I did not add Flickr account.
I use Pure Calendar that uses the standard Calendar content provider. So I cannot turn off the content provider yet. I know Agenda but its not as good as Pure Calendar. But I did add Calendar content via Exchange. I noticed Exchange sync to be much much faster than the old dragging for a minute or two Google content provider calendar sync.
My battery dies to 95 over couple minutes. I guess calibration is screwed through factory reset as well, I should have never updated with the OTA but got tempted by the Memory Management optimization.
Same here, I dony sync google calander and no flickr. My facebook and twitter are set up for 2 hours and Im using juice defender ultimate. I noticed every time I unlock my fone after the screen gone off it starts to sync even though I have set up everything including mail for 2 hours. Calendar process is used by facebook sync and twitter sync so only way to disable it is to stop your syncs but I dont wanna loose my facebook picture sync so cant do that. Hope HTC improve this in the froyo update.
I used autostarts to disable some apps from starting and its been on for 50 mins so far after full charge and im down to 97% which aint too bad but I think juice defenders night mode helps that. Before autostarts I lost 1% every 5 mins. So try that guys.
It's me again, back to report my unsuccessful phone experience today
Well, apparently factory reset and trimming down the number of apps I use did nothing to prolong my phone's life. 10:00 to 18:00, it was down to 28% and losing 1% every 10 minutes, worse when screen is on. Basically, what I figured out is that it's not some rogue app installed on my device that has been triggering this bad lifespan. I also purchased SeePU++ and was really dishearted to see 60-70% CPU when the Calendar Sync process works, and it works almost constantly no matter I've set 2-4 hours frequency to Facebook and Twitter, and I'm using Exchange for Calendars where it has two frequencies set to 2 and 4 hours peak/offpeak times.
Listening to Music isn't good as well. Using DoubleTwist android app, phone remains warm while listening. Not good. Is the phone completely awake while listening to music even if the screen is off?
I've made the following changes for tomorrow, and I'll report again:
* I turned off Wireless Network Location. Not sure whether I'd live well without it, apparently my Latitude will suffer greatly and Tasker won't be able to use its Location triggers (GPS Fix triggers kill the battery in less than 2 hours), so will other apps that use rough estimation, especially if indoors.
* I revised my UnlimitedJuice. My current profile is:
** Timeout: N/A
** Schedule: Keep APN/WIFI disabled (I removed timed schedules as I suspect it kept my device from prolonged sleep)
** Night: Keep APN/WiFi disabled 0-7am (Use it just for the silent mode, otherwise it's probably charging)
** Traffic: N/A (I used to use Traffic to keep connections alive, but decided not to due to prolonged Calendar sync)
** Peak: N/A (obviously!)
** Charger: Leave APN/WiFi enabled while charging (obviously!)
** Screen: Leave APN/WiFi enabled while screen unlocked (obviously, again!)
If anyone is familiar with UltimateJuice, please let me know whether this sounds okay?
I think a culpit was the Schedule setting, as it must have kept my device constantly out of sleep to check my email. Not that I don't want that but until I stick a Mugen 3200 MAh battery in this device, I am wary against it not sleeping well. I also turned off Traffic as Calendar Sync has the stupid tendency to restart itself despite it is not expected to based on user-set frequency. No idea how to control this, no bugfix even estimated.
I think HTC doesn't really care about the life of their phones once they sold them to us. I am also very unpleased to find out how useless those fast 1 Ghz processors are when paired with old battery tech. I am looking at HTC Wildfire and it's 30-50% better battery life with somewhat of an envy. The only company that seems to bother to do something with batteries today is Apple. I won't draw conclusions especially under affect.
I have a question to all ROM-familiar users who have gone 2.2, does JIT improve battery life (through making code run faster, maybe using less CPU resources)?

2.2 ROMs on my Desire make my battery last even less. I lost 1% every 5 mins on any 2.2 ROM.
I get the syncing going on every time I switch screen on. no matter what I have set in the settings. I got 20% overnight between midnite and 9am while Juice Defender was on night mode.
This is very discouraging, Nekromantik. Seems like I shouldn't be as excited about the upcoming August 2.2 update, now. I don't trust HTC to resolve this problem given how every single new device is plagued (Desire/Incredible/EVO) and they do nothing about it.

yeah this has made me loose faith in HTC.
Battery life should be a big factor in smartphones. I should at least expect it to last 24 hours without a charge. Which is good enough for smartphones.
Just gotta add that even though my battery life is not that good, it does show that the phone does sleep as atm in the about menu it shows that the phone been on for 3 hours and been awake for 1 hour 30 mins. Which means it is sleeping but why am I still getting bad battery life all of a sudden after reflashing from Froyo ROM? I did a full wipe including a sd card wipe before I flashed Pays ROM back on. Makes no sense to me.
I'm having a very similar problem with battery life. Android System prevents my phone from going to complete sleep but strange enough - only during night when my phone is in airplane mode.
So I decided to switch off Automatic Network Time. This helped for one night and yesterday the problem reappeared again :-(
So last night I turned off location as well services and again it seems OK for now.
During the day my battery life is OK. I guess I could keep the phone turned on during night as well (as a bypass) but this is not how a smartphone of 21st century should work.
This is a mid-day report but I think I might have finally figured it out. And it's the most ironic solution ever!
I pulled the phone off the charger in 10:00, by 11:00 I was already at 88-86% and rapidly decreasing with only minor phone call activity. Then I turned off JuiceDefender/UltimateJuice and kept using the phone for contact list adding, single profile photo shot with camera, many long calls. Now it is 14:35 and my battery is at 69% - incredibly resistant compared to what I've had by that hour with less phone activity. Also, my phone seems to sleep much longer and more often than before when I used UltimateJuice.
It appears to me now that the reason the phone has been dying on me is JuiceDefender/UltimateJuice. Apparently the latest versions destroy the battery rather than save it!! I told you it's an ironic...
I will be reporting by 19:00 with the phone's actual lifespan over the course of the day but looks like I'll have a winner today.

interesting.
I swear juice defender helped me during the night but I could always switch apn off during sleep. I lost 12% overnight but once I was awake I lost 6% in 45 mins while it was on standby.
It is 21:10 as I type and my battery shows 24% after moderate use day. My phone sleeps more (2 hours use for 11 hours day cycle) and it loses around 1-2% per hour when asleep.
The culpit is definitely UltimateJuice and I am at complete loss how an app meant to save battery can destroy battery.
Also, I noticed that waking my phone when UltimateJuice is not running does not trigger an annoying Calendar Sync (Sync All icon remains non-animated).
I decided to switch off mobile internet and only switch it back on when I wanted to surf/lurk on here/check mail etc. Uninstalled juicedefender but kept plotter. The amount of difference doing those things has been exponential. Before, my battery was dead in about 8 hours use. now it will last 17+. Even use it for music which I wouldn't risk when internet was always on.
For me it is the Location services and Network time that need to be switched off.
As I said I only get battery problems during night in airplane mode so I tested several settings and it seems that both Network time and Location services need to be switched off so they stop trying to update themselves.
Although I would imagine that once you switch your GSM module off that should be enough to also stop Network time and Location... Apparently my assumptions are dead wrong
I think its time to start a worldwide petition to HTC if they please could fix the problems with the battery. I cannot use my phone to call when I am not near a power source. After 15 hours the battery is down to 20% ..its so frustrating.
HTC know there are problems (perhaps the read some forums) and dont do anything about it. Thats not customer friendly.
I think Apple is more serious on that point and investigates every single way to save battery life.
Whats the use of a phone (mine is pretty basic with no specials programs on it) that could not last 1 day?
I think buyers must give a signal to HTC to take these sort of problems serious.

Tips on Improving Battery Life and Speed

I see lots of posts around the Interwebs complaining about battery life on smartphones (specifically Android ones, since I don't hang out on sites that are aligned with evil Apple), so I decided to consolidate my knowledge for people with Slide's to improve their battery life.
DISPLAY
This uses about 80% of the power according to battery use on auto-brightness. On a bright day I can read the screen at about 1/5 position on the brightness bar which cuts down heavily on the battery use.
There's not much else we can do to cut down on screen power usage, so moving on.
CPU
This one requires SetCPU, I strongly urge you to buy it from the Market (it's just a few bucks IIRC) and supports the AWESOME dev. If you're cheap just go download it from that link.
Once you have it you'll want to set up profiles! So click profiles, check the box next to the Sleep profile and choose 480,000/480,000 with ondemand scaler! I have no idea if it actually changes anything but the placebo effect is nice. Next back out of that and set the CPU governor to performance. What this does is clock the CPU to 600mhz constantly instead of scaling between 480mhz and 600mhz as the additional power is needed. It cuts down on choppiness while barely increasing the amount of battery required (in my experience the Slide tends to jump up to 600mhz when I'm not doing anything anyway).
Sync
Turn auto-sync off or set the sync intervals to the highest number possible (once a day I believe). It takes power and most of the time doesn't download anything important. If you really need some data just go and hit Sync Now and, well, it syncs.
Autostarts
There is this nifty little paid application in the market (costs like $1.25 or something) that you absolutely need: Autostarts
Basically applications launch when triggers are triggered, alot of these are pointless and just take up RAM and power.
These are what I have disabled:
After Startup
{Any 3rd party apps that aren't widgets}
Calendar Storage
Download Manager
Voice Dialer (unless you, yaknow, use it)
Maps
Mail
Calendar
HTC Media Uploader
My Account (unless you like the power alerts that take up power!)
Connectivity Changed
Download Manager
My Uploads
HTC Media Uploader

Autokiller
There's an app called Autokiller, it changes the internal task killer's settings as to when to tell an app to shutdown (at stock settings this is almost never).
I use the moderate preset, but you may want to increase it if you never want to have to manually kill a task. Note that this method tells apps to cleanly shut down so data is saved (such as the page you are on in the Browser)
Additional Settings
In Mobile Networks set to GSM only (no 3G)
Turn GPS and WiFi off when not in use
Turn always on data off
Use a silent or vibrate alert method instead of sound alerts
Turn off your screen whenever you can
If you flashed ENG-BUILD flash the updated RADIO!!!!!!!
Protips
Do several battery cycles every 6 weeks (Charge to 100%, discharge to 0%, charge 2 hours past green LED while phone is off)
Espresso is heavy duty stuff, use a non-sense ROM for additional speed
Charging via USB takes significantly longer than charging via AV
Live Wallpapers will use lots of battery
Use wallpapers formatted at 480x320
Limit the amount of widgets you have to around 5 (unless they are from the same app, like Beautiful Widgets) they constantly refresh and do their thing in the background
I learned most of this thanks to enatefox's guide which I modified to suit the Slide, a coffee fueled mind, and general observations. If you have anything to contribute please let me know and I'll add it!
check general, few threads there on this .. it seems the development section is the hot spot around here..
an APN widget will do wonders, or even juicedefender.
i disable APN until I need it. screen is about 30% always. after everything i do i lock the screen.
on a normal days use (1-2hr phone calls, 30-50min of browsing the net, a ton of text messaging, and streaming slingbox) I'll have about 60% battery by 10pm.
great guide. thank you.
does autostart continually kill those processes? I ask because that long list of bloatware you listed is what is irritating me on my slide and even when I force kill them all they restart themselves every 5 minutes. I have taskilller set to kill them and they come back like the herp constantly.

Autostarts does not 'kill' processes, it disables them from running when certain triggers are triggered.
For example if SpywareApplicationOVER9000 runs everytime an application is installed, and you disable it in Autostarts, then it will not run when an application is uninstalled

Desire battery observations

I know you guys might be tired of these threads but I thought I might as well post this.
My desire is fairly new(Less than a week) and so far its been good apart from(What I though) battery life. i've been trying to improve it and I think I might have "some" progress.
Currently I'm running DeFrost 4.9 with HAVS @ 1137(4.9a) kernel with the very latest radio, I also use only 2G networks(No 3G here). I got two Gmail accounts but only one has sync(The other one is merely for Google checkout CC purchases), I got one Facebook account set to sync every hour as well as LP Facebook widget also set to sync every hour. I also got FancyWidget syncing weather every 3 hours. Apart from these I got Nimbuzz running 24/7 in background. The battery is calibrated and yesterday I did a complete discharge/recharge.
Now I plugged it off the charger 2 hours ago, it was at 100 according to spare parts. The brightness is at 2%. I did some lite browsing, browsed a bit with Tapatalk Pro and 40 minutes ago went to a market nearby. During my trip to market I had Google Navigation turned on navigating me(During both, the trip to the market and return). Now while making this post the battery is at 81%. Does it sound right?

How much time the display was on? How much time was the GPS on?
Be careful, don't be happy before time. I did the recalibration too, and found that my phone would turn itself off at ~20% remaining battery.

During the navigation, about 5 minutes for display, 40 minutes GPS during which I went into a building for 10 minutes and it probably lost signal then.

Sound about right. 8.5 hours with your facebook and other syncs. I don't see any problems at all. Mine does this too.

First, in the night put the phone in airplane mode (I dont think u need to check ur facebook )
Second, check if u have useless programs that are using cpu in background, if is this the case UNINSTALL that program and CONTACT the developer. We dont need to kill those kinds of app, we just have to UNINSTALL if an app doesn't work properly, untill the developer will fix it. If all people will do like me, the market will full of great apps
I don't think I have any useless stuff running in the background. All I got are 2 widgets(Facebook and Twitter) syncing every 1 hour and 3 hours respectively, one Fancy Widget fetching weather and Gmail push for one account. Is their a way I can check all the services running in the BG?
EDIT : Forgot to mention Nimbuzz running 24/7.

I won't rehash all of what has been heavily discussed by now in much greater depth, like in the FroYo Battery Usage thread. But auto sync with such social applications and you set yourself up for low battery runtime to begin with. Especially with a constant polling IM and/or battery widget running too. Don't expect much.
Anyway, I don't use them but weather, stocks, 5 mail accounts and news is set to auto-sync every 15 minutes and WiFi is always running if available. Last discharge as soon as I connected charger ended at:
http://bit.ly/c6R59G
http://bit.ly/bmM9oN
http://bit.ly/cMlnun
http://bit.ly/akPvr7
I slept twice for 7-8 hours each on that charge and it includes all of my daily usage including listening to 127 minutes of MP3 via headphones with the screen off.

Hmm Wi-Fi + Nimbuzz really screws up the battery . Last night I turned off the Wi-Fi and slept for 8 hours. I had 46% battery before and in the morning I had 40%. I also have disabled Auto-sync for Twitter/Facebook widget and Facebook app. Now the only running services I got are Gmail push, FancyWidget weather and Nimbuzz.

How did you manage to get such good battery life? Your phone lasted for over a 32 hours period which included 6 hours of display. And that too with stocks and News syncing every 15 minutes. Does Nimbuzz really screw you that much?

Well now datz some good battery. Which ROM are you using? Which Radio are you using?
I don't have any account/social networking syncing. Don't use wifi more than 20 mins a day. Brightness 20%. NO GPS. No Bluetooth. No stupid application sucking battery's power. If my screen is off I lose about 3-4% for a period of 5 hours, so no app sucking the battery in the sleep mode.
If i use EDGE when the battery is Full for about an hour I get battery drain of 20%
Would love to know more details on which ROM, Radio and your settings.
OK. There's not much I can say except what other guys who know better than me said here http://forum.xda-developers.com/showthread.php?t=743172
It's all usage/config/settings dependent. There's no secret sauce. Some setups and usages last shorter than others, yet further, some drastically shorter.
Firstly, I don't change something working well nor move from a setup until I've worked with it the best I could. The ROM I use daily is HTC 2.2 with root. The radio is some old one that worked perfect for me: 32.43.00.32U_5.09.00.20. I can give you some details so you can characterize the battery performance on mine better.
- H.264 sub 2.5Mbps 800*480 video playback at 18% brightness lasts 5.5-6.5h with about 15% remaining. This has been repeated more than 50 times since March.
- My average runtime used to be 13-18h since March but I knew something was wrong and drawing more juice than necessary. I kept looking (mainly at the logs). It took me months to figure out it was a few things including my build.prop WiFi/cell settings, A2SD+, my GMail install, battery widgets, eBuddy, Titanium Backup, Chrome2Phone, Pure Calendar/Grid widgets and my 3G baseband reception. Some app versions were buggy and constantly polling and returning random errors in the background. I had to eliminate them one by one.
I rectified such problems entirely and removed all the unnecessary apps installed which I rarely used. I had to revert back to FroYos A2SD with the install location mod. That took me to todays battery runtime which I'm very happy with. Chrome2Phone for instance could stay installed and be disconnected when not in use to avoid the large background drain it caused.
- I run personalized colour calibration with lowered overall luminance but more red and green with less blue sub-pixel luminance. Very near D6500 whites. I also keep most apps and my homescreens dark when and where possible. I disable button LEDs through a widget when not required (much).
- 24-39h is the norm for me in typical usage. Among much else that always includes a few short calls, some YouTube, some StreetView, some TapeMachine (audio record), some Scan2PDF, some Aldiko, some Chrome2Phone and Fox2Phone, some Tapatalk browsing, some XDA app browsing, some Quick App Clean Cache, some SpringPad, some Adobe PDF, max 15mins of MP3 playback, heavy net and NewsRoom browsing, 150-250 emails and messages and constant sync with what I listed priorly. Always 2G though, and whenever I reach areas I know have bad or no reception (causing high drain) that I'll be staying at for more than 10mins, I disable cell (frequently). I've nurtured the habit of putting the phone in standby after every use too.
- 6-9.5h display on aggregate is the norm for me. I use lowest brightness possible or 18% typically. 50% in very bright, direct summer sunlight. Just now the battery ran out after 26 hours with 9.2h display on, 13.5h cell on and 22h WiFi on.
- I have apps I consider junk removed: Facebook, Footprints, etc. The lot. So no sync or auto running for them or their widgets in the background. I also removed the base GMail because logs showed me it carried on running sync all the time even when not set to. I forced the latest GMail APK in and it has no such problems. I removed all battery widgets installed except one since they drain heavily.
- Heavy usage like GPS, lengthy calls, video recording and playback cuts the runtime down drastically which should be conspicuous. I can drain the battery fully in 5h with everything max and running.

Thats some damn battery life you have there. You are on a Sense ROM? Do you actually use Sense? If so you're either exaggerating or I'm a total fool(I'd prefer the latter).
I've been trying to fine tune the battery, currently I'm using DeFroST 4.9 with SVS 998Mhz @ 1275mv kernel with 17_2 radio. Re-calibrated the battery yesterday and compiled a custom wi-fi module containing fixes for sleep disconnection today morning.
I left it at night around 3 AM with 99% battery, turned off the Wi-Fi/EDGE but kept mobile on. In the morning(Around 9:30AM) I was at around 91%. Gave it a quick charge to 100 till around 11:15 AM. Disconnected it and from 11:20 to about 11:40/45 AM I had quite a heavy chat session over Nimbuzz with my friend. My battery went from 100 to 94% in that time. After that I pretty much left it, picked it up to check a mail once or twice and sent a few messages over Nimbuzz. It is 1:40AM now and I'm down to 89%. All of this was over Wi-Fi, GPS off, Bluetooth off, no tethering no nothing. I got no Facebook/Twitter auto-sync. Only FancyWidget(every 3 hours) and Gmail Push. Brightness is at 2%(Although even then it is a bit bright, maybe it is just me).
I am using Extended control widget to see the power percentage.

Whoa ! Amazing post there. This should keep me occupied for quite some time to figure out what the heck is going on with my battery. The battery life what you are getting is really good and that is what everybody should get provided they figure out what the heck is sucking their battery that bad. Lotsa things and apps you have said drains the battery is on my phone and I haven't even started looking at logs in detail. Itz been only couple of weeks since I have this phone so I'll defn start looking into this issue.
Few questions
1. What issues did you have with your build.prop?
2. What battery widget are your currently using ?
3. You have mentioned A2SD+ also is a battery drain, was it a particular ROM's implementation of A2SD+ or older version of A2SD+ or A2SD+ in general causes battery drain ? Would be great if you could link us to the location mod
OK, It is 7:05 PM now and I am down to 70%. Nimbuzz was on all the time along with Wi-Fi(Although I don't know what happened but it switched to EDGE as if it lost Wi-Fi connectivity, Wi-Fi wasn't disabled, just disconnected). And I pretty much haven't touched it since 1:40 PM. Not as good as I hoped, but still kind of decent.
And my Wi-Fi strength isn't that great either, it is either 1 or 2 bar out of 4.
Well, I haven't done any such kernel modifications intentionally. Never had any need to either. 14.5h since last charge now, cell on 5h, WiFi on 12.5h, display on 2h and 76% remaining (actually, those stats were collected and written an hour back). The Desire display has been verified to consume at least 70% of the total device power when the screen is on. So you can't get more hours with display on if it didn't run as such.
It's HTCs ROM so of course it is using Sense. I can't do without most HTC added goods in Sense. Let alone the Mail, Bookmarks, Calendar, Stocks, Copy/Paste, Lookup, Clock, Gallery and Camera apps and widgets. The widgets I depend on work well only on the HTC ROMs I've tried. The missed Sense goodness combined with the bugs and problems I had on AOSP ROMs were extremely problematic so I moved back. Even my video recording and native playback is much better on this ROM.
To be frank, you've hardly had the phone so you'll learn much more yet. And it comes through search->reading->experimenting first. 1-2 weeks is too little for even figuring out most of the basics, unless you're moving from a similar phone and OS. For one, you'll need to actually read the linked thread to see what many observed and experienced. It took me and many others 6 months to learn things and get to this stage. Every other day I was testing and monitoring. But be aware that you can't, for instance, have the exact same setup and usage as me to have the same resultant battery life.
Had you read the linked thread you'd also be aware by now that bugs were filed for inaccurate % readings by Androids Battery Usage section. However, its time tracking was reliable in my testing.
- On your typical full discharge, how much time and % is listed under Display on?
- And for cell?
- Which A2SD are you using?
- Static wallpaper/color?
- Animation settings?
- Location on?
- Network location errors in logcat?
- Cell network chosen auto or manual?
- Did you mention all the widgets on all homescreens?
- OSMonitor/CurrentWidget values in idle screen on and idle screen off?
I use EC and SwitchPro widgets too but their battery widgets (like you mentioned) are known as ones with high consistent drain. The EC dev also corroborated this in its thread under the Themes section.
The 'idle' drops you get don't make sense to me unless there's fundamental hardware/software activity you haven't properly monitored and logged. Even kernel and I/O usage in the background. You'd be surprised at the difference one buggy underlying feature can make.

- HTC Desire via XDA App -
If you're actually asking those questions, here goes. Note, I am at 66% and the time is 8:56PM. And after this I'm gonna nandroid this ROM and try SuperVillainHD just for the kicks. Also, can it be that since the phone is relatively new, the battery is not up to its full potential?
Q1, 2) Battery usage is :
Display: 35% (35m 37s)
Wi-Fi: 20% (9h 44m 22s)
Cell standby : 15% (9h 44m 22s)
Phone idle: 14% (9h 9m 42s)
Android system: 6% (CPU Total: 9m 35s, CPU Foreground: 27s, Data sent: 7.82KB, Date received: 11.38KB)
Nimbuzz: 4% (CPU Total: 6m 46s, CPU Foreground: 2m 54s, Data sent: 298KB, Data received: 851KB)
Android OS: 3% (4m 1s)
Voice calls: 2% (45s)
Q3) I'm using DeFroST ROM with A2SD+
Q4) Yes, I'm using a static wallpaper
Q5) Animations is set to : All animations
Q6) GPS is disabled, if that is what you mean.
Q7) How can I check this and what would it show?
Q8) Didn't touch this, so I'm presuming Auto.
Q9) I'm not sure, so here goes. I got a Twitter widget, Facebook widget, both are set for manual syncing. Got FancyWidget syncing every 3 hours and several harmless icons. I got 3 bars of Extended Control widget and a google search widget
Q10) I don't have those, are they available in market? Do they consume battery?

I'll have to open the file for that to check exactly the changes I made. I didn't really follow anyone, just went off my own understanding and intuition. If I try to access the dir or open the file whilst the phone is not in Recovery, it'll force a reboot so I'll give more details later on this when I'm near a PC.

FroYos A2SD was nice but I needed much more space and was trying A2SD+ with various ROMs as well as manual use on HTC ROMs. Endless problems such as very remarked, consistent sluggishness in basic functioning, total boot and app load slowness, including high, persistent background CPU and IO loads and very poor SD card transfers over USB and WiFi made me sack it. I lost a class 4 16GB Kingston SD card with errors inside 2 months. I transfer 2-4GB in/out daily and many transfers started failing. Widgets bugged out frequently when you needed them most and had to be all re-setup. Video record and playback became dis-able. The phone became useless except as a toy. That's not what I bought it for but as a helpful companion. I eliminated everything in question. It was simply the SD card [over]use compared to internal memory.

[Q] Battery Drain in Airplane Mode, and even otherwise - Andromadus Mimicry

Hey all,
I have a rooted Desire Z, that's almost 2 years old. I had been using the Virtuous Sense ROM for the most part and had been quite happy with it. Recently, I figured it was time I switched to ICS. So I flashed the Andromadus Mimicry ROM and have been loving it ever since. My only gripe with it is the battery life. I have been meaning to test it out extensively before I could bother the DEV with my nooby queries, but haven't had the time to do so.
When I check Settings > Battery, the screen always seems to be using up most of the %. I have searched through the forums and have done the following, in addition to a few steps that I could think on my own -
Re-calibrated Battery Stats
Clear cache & devklik cache fortnightly
Brightness - Set to 20% (No Auto)
Set to dim after 30 seconds
No render effects (ROM specific I think)
Animations are On.
No Bloatware Installed (Facebook, Twitter, Chrome, etc)
Sync is Auto (I need this)
Froze Google Maps and few other unnecessary background apps that I rarely use with Titanium (using Watchdog to monitor what was eating up CPU)
Disabled Google Backup
Wifi is always Off (I have to depend on 3G for my connectivity needs)
No Battery Saving Apps or Auto Kill Task Managers installed.
News & Facebook widgets set to manual update.
V6 SuperCharger with stock Services.jar.
CPU clock runs @ 245 Mhz on idle, which is most of the time.
GPS is always Off
Google's Location Service (Wifi & mobile network) is On.
Coming to the point, last night the phone was fully charged to 100%. I decided to turn Airplane mode On before I went to sleep to figure the drain in the absence of networks. Woke up to find 78%. That's 2.2% per hour. I checked Better Battery Stats and it seems the phone was awake for the whole ~10 hours. The culprit seems to be GPSLocationProvider. Note that the GPS is Off ; so this has to be the Google's Location Service (Wifi & mobile network)? Disabling this would be inconvenient because it's needed for Weather, and a few other things.
I'm attaching the screens, because I'm pretty new to this and would like to see what people who know more than me have to say about this. A drain of 22% in Airplane mode isn't normal and is crazy, right? Or perhaps,it's time to get a new battery?
PS: The battery has drained a further 20% since the time I took the screenshots, while I was typing this. I merely used the phone for a few messages and to check my mail. (see second-to-last vs last screen)
Radio - 12.56.60.25_26.10.04.03. Signal Strength is usually ~ -89dBm. I have noticed people claiming that the .19 radio is quite battery-friendly but I live in India, so I had to go with the WWE radio that seemed the latest. I didn't think it'd work here. Perhaps I'm wrong?
Any insights offered would be greatly appreciated.
It's an app calling the location services api. Try disabling Facebook and/or whatsapp and see if that helps. I'm unfamiliar with either of those apps, but I've heard nothing but bad things about the Facebook app, so that would be the first one I'd remove to see if it helps.
This goes without saying but of course make sure you've done a full wipe of /data since coming from your old rom. Hope that helps. I'm currently sitting at 12 days since my vision has been unplugged in airplane mode (radio off, wifi off, etc).

GPSLocationProvider - Reboot to Fix.
Thanks for your input, blk_jack. I did do a full wipe before migrating. As suggested in your ROM's OP, I don't use the Facebook app. The Facebook entry seen in the screenshot belongs to the Facebook Messenger app, which might partly be the cause. Upon further searching, I found that many people have been complaining about this issue on many different flavors of ROMs (ICS / JB) and hardware (HTC, Samsung, LG). Let me elaborate.
Searching for 'GPSLocationProvider' brings a ton of threads about this issue. I will post here whatever I could gather from these posts, for the benefit of others who face this.
Some people get this wakelock if they use GPS for anything and then turn it off. For example, if you turn on GPS, use a map application for a short while, close the map application and turn off GPS, the wakelock is born. Even if you kill any active map services, it will still be there and ends up draining your battery.
It seems to be chiefly caused by apps that use Location such as Google Maps, Facebook, Facebook Messenger, etc. Turning off all location services is advisable.
In some cases, the GPS does not turn back on until the phone is rebooted but that is not the case in this ROM. GPS works when turned On.
To get rid of the wakelock caused by GPSLocationProvider, rebooting seems to be the only working option as of now.
There is a step-by-step instruction guide (written by Karpfenhai) in the [APP]BetterBatteryStats thread OP, that deals with configuring autostarts, which apparently fixes this issue. I'm yet to try it, so I can't comment if it works or not.
I wish I'd been smarter and searched for 'GPSLocationProvider' instead, before creating this thread. Thanks for your time, anyway.
Screen Off Widget/Shortcut on Desktop?
@blk_jack
If I may use this opportunity to ask you something else related to your ROM.. I just found out that I don't have 10 posts yet, so I can't post it in the ROM thread.
Is it possible to create a widget/shortcut on the desktop to turn off the screen, perhaps by using the Launcher Activity options? I am currently using the one that's there in the Notification Drawer (Power Widget), pulling it down each time to turn the screen off is a tad inconvenient. The desktop Power Widget doesn't seem to have the Screen Off option. Is this possible at all without having to use an external app?
Yep, I have a nova launcher gesture set to run the root app killscreen.apk (search google).
You could add that app to your home screen too.
