Hi guys,
I have to say, compared to my HTC Hero and Modaco 3.2 rom, the battery life on the Desire seems pretty poor to say the least.
Do you have any tips? I know there are mixed views on task killers but whats the general consensus? Seems like every app that gets opened, seems to stay open forever or atleast open in the background on this thing. Is that good or bad?
Does the Gmail app which is push based I believe consume less battery than say the HTC Mail app used to sync about every half an hour?
Have you discovered any particular HTC apps that drain more battery than normal?
I've already disabled Facebook and Friendstream completely, use seperate apps for those.
It just feels like the battery eats away even when the phone is just sat there with the screen off, sure I have 3G on but Twicca is the only thing set to update every half an hour in the background and the Gmail app on push no doubt.
Any tips?
pretty sure if u slightly decrease the brightness of the screen and stop all data connections unless you want to run them will help the battery life
disable live wallpapers
disable auto updates
disable 3G (just for the sake of trying)
decrease the brightness or make it auto (dont put it to the max)
put plain black wallpaper as background (trust me it consumes 40% less than the colored wallpaper, again, do it just for the sake of trying)
try this for one day and see if you get anything different
I have the brightness set really low, don't use live wallpapers.
I would disable 3G but that kind of defeats the purpose of having twitter updates and stuff, one of the main features of the phone.
Just checked and Twicca is only set to update once an hour, this is really weird.

I saw somewhere that you can see what app is draining your battery life in the notification bar, just open the notifications bar and go to battery, and see if you find anything related there
I have the phone for 3 days and I'm still in the stage where I play with it all the time.
Day 1: fully charged at 1PM, used the phone pretty much non-stop till 10PM and finally plugged it in with 3% left;
Day 2: unplugged the phone at 8AM, had it in stand-by for couple hours, then used it non-stop for 2 hours, then 4 more hours of stand-by, then it 2 hours continous use. The rest was more or less stand-by. Plugged it in at 10PM with around 10% left.
Day3: used it quite a bit on and off during the day, still have 34% left.
I don't do any fancy power saving, though I don't like apps updating themselves, except for mail. However, I use WiFi when I can and I listen to podcasts whenever I walk/drive somewhere.
It's a bit too early to draw conclusions, but at this point I'd say that Desire's battery life is much better than G1's (I had 1600 mAh battery).
Of course it all depends on particular use case. Also, maybe the network is spotty in your area - that might drain a lot of battery.
I've heard some people say they get 3 days out of their desires and others saying they get just over a day.
This thread it would be great to collect a list of people with desires and their average battery life as well as a list of apps they have installed and widgets on display and maybe the rom they are using.
Just trying to work out
I'm going to collect data and put something up tomorrow - but I noticed last night that my battery went down really quickly when my Alarm went off (using Gentle Alarm) I also confirmed this using JuicePlotter which showed the battery sharply decrease just at the same time in which my alarm was set to go off.
I also noticed that having wifi turned on didnt seem to effect battery life that much...
Yeah my battery lasts really well leaving WI-FI on too. Not sure why others have an issue with it.
My battery will last a day tops turning on from 7.30 and off again around 12am ish
During day I will use Seemic (on manual update) and use FB on net every now and then.
May occasionally go to the Market for Updates.
I only use mobile Network when I need to so I turn off and on when required.
I will play Word Up and Solitaire for 30 -40 mins a day roughly.
Battery % will vary between 65 - 45 by 6.30 pm
Today it is down to 75% at 2.10pm - although I've not played any games today so far.
I bought an X10 and returned it because the battery wouldn't last even a day despite having all kinds of task-killing crap installed.
Then I bought a Desire and had the same problem - 6, maybe 7 hours of battery.
I found a post on some obscure blog that helped me track down the culprit: there are apps that don't let the device go to sleep completely. I had two of them. And Android (at least the HTCs) have a built-in function to see exactly what those processes are:
From the dialer: *#*#INFO#*#*, choose Battery History from the menu and then Partial Wake Usage. Nothing should have more than a tiny fraction of a bar. But on mine, Grooveshark was using 99%. I uninstalled it, tried again a few hours later and saw that Mikandi was using 99%. I uninstalled that, and now I'm getting more than 24 hours of heavy use.
Some apps just don't behave.
Why would Dialer App have such a high network usage?
It shows up as using a lot of network!

Wouldn't the dialer use the network to call people when you dial?
Thanks for the "cheat code" on the hidden menu. Very interesting.
I can sometimes squeeze 2 days out of my battery. I'll only get a day and a half on this charge though because of lots of txting and facebook use.
I found this menu option in Settings > "accounts & sync" > Background Data. I turned this off and seem to get a little more battery.
Changing the brightness down a bit helps, and i'll set the screen timeout to lower as its at 1 minute now. Plus If I use friend stream instead of the facebook widget then it updates when I want to and doesnt keep active.
Least amount of battery time i've had is a day. I never turn my phone off.
I never get a full day out of mine, maybe 8-10 hours max... I have no idea how some people claim 3 days, I'm not exactly a power user!
Stock ROM (not a provider one, just generic) on T-Mobile UK network
Wi-Fi and GPS off
Widgets: Standard Flip Clock, SMS, FriendStream, Stocks (2hr update), Agenda, News (2hr Update)
Market Programmes: K9 Mail (1Hr e-mail updating), ES File Explorer, Shazam, Voice Search, Pkt Ebay, Tricorder, UK TV Guide, GBCoid
In Standby (screen off), not using web, not calling, not texting, not using apps, I lose around 10% per hour, faster if anything at all is on.
Oddly, despite the very poor (for me anyway) standby life, in call life seems really good, I made a call last night for an hour, where phone was in the orange phase when I started and still hadn't gone red at the end...

I wanted to try turning background data off but sadly the market does not work when you have this turned off (a warning pops up when you try)

True re the dialer. Was thinking network as on net use.
anyone got background data or mobile data turned off?
if so whats your battery life like?
also anyone tried with 3G on and compared to GSM ONLY?

Well the only app that have a bigger bar is Android System... Is this normal?
Settings ; About phone ; Battery ; Battery use and it will tell you when it was last unplugged and what has been using it.
4h 27m
Cell standby - 45%
Phone idle - 45%
Wifi -7%
Android system - 5%
Display - 2%
Obviously you can see from that I've hardly used it. A few texts, checking email periodically. Display brightness is on full, weather update is set to manual. Only have a few apps installed. Main one being data counter widget.
2000kb wifi
780kb cell.
Oh, and SystemPanel, tells me I have 93%.
Switch off 3g when you don't need it,this can nearly double your standby/idle time ,use a 2g-3g toggle if its a pain.
Juice defender with its plotter can give you very useful info on when your phone is using its battery the most.
On idle with 2g 1% per hour is normal, with 3g 2-4 %.
As soon as that screen goes on start thinking 15-20% per hour!
Most smart phones are the same,my x1 ,touch pro all got caned when I first got them,but a bit of experience and a few tweaks later they were doing 3-4 days.
Also flatten it and fully charge it when switched off helps too.
My battery life is pitiful too, im a pretty light user now ive had time to play with the phone for a while but battery will always need to be put on charge by around 10pm when only unplugged around 7am the same day.
I bought up the partial wake usage list and UID followed by a number is using twice the power of Android System.
Does anyone know what the UID is?
My battery life was rubbish until i updated the radio version to 32.37.00.32U_4.06.00.16_2. I am also using MCR3.1
Before my battery life would be fully discharged within 7 hours. Now i have 1day+ Not too sure as i now have a brodit car mount that charges my phone during my commute.

Stating the obvious, but if you don't use your phone, your battery will last a long time!
Personally I need to use my phone (otherwise why would I have bought it) so have push email running with full Exchange sync 8 till 8, FB & Twitter syncing once an hour, spend a couple of hours a day making calls, connect to WiFi using my iPass account whenever a hotspot is available and spend a lot of time dealing with emails etc.
I put my "less than a day" battery life down to the fact that my screen is on and doing stuff for much of that time.
Of course if I just leave the phone on the desk at the side of me and don't touch it all day, even with push mail and all that sync, if the screen is not turned on much, I get 2 days.
It's the screen that eats the battery. The more it is on, the shorter the time between charges.
Wow I don't understand how you people get such amazing battery life!
I am no noob anymore regarding Android and Smartphone's in general, so I understand most 'hints & tricks' in this thread. But simply for me this does not work.
Some important stuff:
- I ALWAYS have 2G on, never 3G.
- I use wifi at home and in most places I go
- I have almost everything set to 'manual' updating
Ok.
For example my last situation:
I unplugged it at 23.30 yesterday. I used it for a little bit, over wifi. Checking twitter, surfing the web, watching some video's in HTC Flash Player. I went to bed around 02.00, watched some Law & Order that's why it was so late. So before turning off the lights, I turned wifi off. The battery was around 80-85%, from what I remember.
I wake up at 12.00. The battery was still above 50%, that's for sure. I do some facebook, twitter, news, etc. All over wifi.
And now, just before 17.00, my battery was dead (while I almost typed this entire story on my Desire -.- I was pissed). So that means, about 17 hours? Which about 10 hours I slept and the phone was doing nothing, over 2G!
So yeah... and when I read all your story's about 2 days (48 hours) I am really like: WTF
Some more details:
-No live-wallpaper. Just the black 'carbon' one.
-I used to use LauncherPro beta, but battery life was just as bad. Now I am back on HTC Sense. I have some widgets, like the Calander widget, a small music widget, bookmarks widget, etc.
-I tried to find out what uses the most battery while sleeping with that code and it showed Android System. So nothing weird there.
-Again, everything set to MANUAL updating
-ONLY 2G.
-Brightness set to auto.
So really, I think it's my wifi that sucks the battery life out of my Desire. I remember when I went on a trip and was just 'listning' to music, my battery only dropped like 10 to 15% in 3 hours.
-----------
Btw, I remember that this 'some people have great battery life some people don't' story was the same with the HTC HD2. The only different thing there was that I was one of the people with the 'good' battery life. Now I am on the 'losers' team
Any help would be great!
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.

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.

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.
I'd like your opinion on this. Today I had my phone mostly at silent and the display was off most of the time, I was attending a workshop and pretty much did nothing with the phone. Before starting, it had 100% battery but when I came back it had dropped to 63%.
Not only that, it also used 3MB of B/W today over the cellular network(Using netcounter for this). For the B/W I got 1 e-mail account set to sync contacts and e-mail as the items arrive(Push mail) in HTC Mail. Now until a few minutes ago it was also syncing News, stocks and weather under HTC's default settings.
I have VillainRom with 17_2 baseband, the phone is pretty much new and the battery is calibrated.
Note : I'm mostly talking about a period of 8 hours.
OK I flashed LeeDroid ROM and 30_2 radio. I also tried to re-calibrate the battery, but it seems it was calibrated since after removing the phone from charger, shutting it down and plugging it back in it immediately went green.
Now I got one gmail account which has nothing to sync, one exchange activesync account set to sync as mail arrives(push) as well as contacts, one HTC Facebook account set to sync every 2 hours, weather to sync every 3 hours and that too only of my location(I removed other cities). I also got Nimbuzz running and Wi-Fi sleep policy is set to "never", brightness is automatic. Hopefully this'll keep my battery happy.
Lets see how it goes, I plugged it out 1 hour ago(It was at 100%), now it is at 92% although I believe the 90-100% span is kind of delicate and runs out quickly. Not to mention that I also browsed for a few minutes.
Totally agree on the randomness of the battery even when charged. Some days I have a wifi surf whilst having my morning poo for 5 mins and I'm down to low 90's/high 80's. Today I'm still on 99%. My poo lengths don't change much so something flaky is going on.

Heh, I know what you mean.
Its been a bit more than 4 hours and I've had a few calls, browsed the web a bit and read 5 mails and send/received 4 texts. Nimbuzz has been on constantly along with the Wi-Fi and I'm having 82% battery. Seems OK considering the usage.
Hi there,
I'd love to hear about your battery performance. It seems to differ so much between useres that it's really strange. Maybe we can also find out which apps/widgets are too heavy on the battery.
I''m currently using SGBS Rom 2.5 stock.
My average performance is barely a day with moderate use.
I'm using:
- two E-Mail accounts, one with push
- HTC friendstream widget
- HTC google calender widget
- Google News widget
- display brightness set to the halfpoint
- some hours of WLAN a day, always on with mobile internet
- a little surfing, SMS
that's it. With this user behavior I now got about 25 hours out of my batter. Display is 28%, Phone inactivity is 21%, standby is 16%, WLAN is 13%, Mail is 11%, Phone is 7%, calls are 4%, Android OS is 3%.
I deactivated most of the syncs, push is active for my main active E-Mail, the other one is every 15 minutes. Rest is "once per day" or not at all, HTC sync is deactivated.
Is this performance normal? Any ideas? I'd say it's ok but there are people out there claiming they get 48 to 72 hours out of their phone with moderate use. That's quite a difference.
Thank you!
Battery performance differs from user to user and rom to rom. Some roms will run better than other roms and it also depends on what the user has installed on their phone. If you have a fair amount of widgets or just stuff that runs in the background then your battery life will be worse than other people's. CPU frequencies and governors can also come into account.
So, what's the best way to find out what influences your battery life most? I know there are those stats which I posted but they really don't help that much, do they?
The stats you gave fluctuate too much. The main thing is to keep an eye on your apps. See which apps are running in the background, see how much memory they're using. Widgets are another thing to be careful of. I don't use widgets, just the one since I'm on sense, but having lots can impact battery life. You can try and use an auto run app which allows you to stop apps automatically running on startup.
Try not to use live wallpapers and screen brightness.
Punched in..
I charge it every 24 hours on the average - goes from 100% to 30%. A few phone calls, some emails. Not heavy on messages. Some Internet once in a while. Needs an extra recharge on days when GMaps or GPS or Angry Birds come into play.
Have seen some improvement from Stock Froyo HTC ROM to (over the last week or so) AOSP (Redux2 Test Builds).
Ok then, new stats. I got about 10 hours now with an active time of almost 2 hours and I'm a 70%. Had a short phone call, emails, that's it. Rest was just idling over night.
Main battery culprits at the moment:
Mail 30%
WLAN 19%
Standby 14%
Phone inactivity 13%
Display 11%
Calls 8%
Phone 4%
Android OS 3%
My App Stats:
Options 15MB
Maps 6MB
Calender 9MB
CSPeopleSyncsService 3,9MB (?? no idea what that is)
Google Services 8,9MB (no idea either)
Mail (5,4MB)
Sense 4,3 MB
Market 3,7MB
Mail (again) 6,6MB
152 in use, about 200 free.
Widgets:
Calender
Friendstream
Weatherclock
Google News
Any idea?
So first report regarding the new radio. It definitly works fine with SGBS, can't say yet if batter life really is better:
I'm now down to 68% after 15hours. At least 8 hours of those are flight mode over night. WLAN was active the whole time. Display is the main battery culprit, Telephone "inactive" is right next to it. Then WLAN with about 18%, then Handset standby with 16%.
So I obiously don't know what thelephone "inactive" means, that's still pretty high. But I think handset standby is a little lower. So maybe the radio helped with that?
BTW, I used the music player yesterday for about 40 minutes. And had a short GPS test (works fine with new radio) so I guess 70% after 15 hours is ok...
