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...
This seems strange.Yesterday after upgrading to gingerbread ( with the RUU because the OTA didn't work for me) I got a huge battery drain.Over the night I got a loose of 40% and now only 3 hours after unplugged and lost 20%.
I only took a few pictures and a phone call.
Only few apps installed since i got this rom since only yesterday.
Anybody experienced this and is there a fix?
Hello,
I can confirm this.
I have also a high battery drain with ALL Android 2.3.* ROMs.
I use the recommend Radio for each ROM and I've checked the RIL to be sure the Radio is correct. But doesn't matter, current in StandBy is between 30 and 50mA.
Only if I turn off WLAN and Mobile Intenet, then I have normal values between 3 and 5mA.
With FroYo I can leave WLAN and Mobile Internet enabled and I had 3-5mA in StandBy
It could not be an application, because I've tried this with a fresh install without Google account to avoid the installation of external apps.

you'd have to edit the build.prop and change the rescan time from 15 seconds to 30, 60, 90 or 120 (or whatever you perfer the rescan intercal to be at)

Try resetting the battery stats by doing the whole charge, lead out, charge, turn off, charge etc. thing.
Also, whilst not a stock RUU I did find it took a few days for the battery drain to calm down a bit. First instal lowest was around 50mA but adfter a fe days it went down to 4-5mA.

Thank you for your help
What does that value do?
Is that the rescan value of WLAN?
The current stays high even if WLAN is off and mobile internet is on.
Only if both are disabled I get a low StandBy current.

Yes I know this, and I've tried this every time I was flashing a ROM (I mean reset the battery stats)
After a few days? How many days do you mean? 2, 3, 4, 5 days?

But why this problem does not exist on froyo?

Varies but on average I find it takes about 3 days to settle to a point where I see a consistent drain.

Unknown. It's not 100% due to GingerBread as I've only seen a handful of people complain of this issue (relatively speaking). I see more people saying how much better their battery life is after the update than saying it's poorer.
Doesn't help I know but makes me believe that this is maybe a Network / Radio issue in that the new Radio with GB does not play well with the Network. We had this a few times on the HTC Hero.
Ok...i have airplane mode on for about 2 days.in those 2 days i almost didn't use the phone and got only a 7% lose.As soon as i used the camera(recorded around 15 min) it got down to 50% .
I will test it tonight widought airplane mode on and see the resoults.Also wifi seems to a lot of battery in comparance to froyo.

I haven't noticed these problems with CM7. I got 2.5-3 hours per 1% of drain in standby using juice defender.
If you are finding that turning off data etc is fixing the problem use juice defender. Even the free version will help a lot as it will stop your phone using data willynilly and instead turn it to a periodic sync. With the paid version you can have it stop all together during certain periods or increase doing certain periods. Aka stoping at night and extra during busy hours at work.
Should be a good fix, though it is only covering up the underlying problem still.
Can't really recommend the app enough. With it my phone only uses data when I tell it to (like opening facebook app) or periodicaly to sync and check emails etc. I do use the paid version though for the extra features.
totally agree. i have been using juice defender for about a week. its been a big help. just bought the ultimate a few min ago. going to start customizing.
sorry that i dont have any data yet to back up my statement. maybe in a future post.

im using Leedroid 3.0.3 and i dont get any such battery drain..
tbh im getting a better battery life from GB than from froyo..
on standby currentwidget shows me between 4-7ma with wifi on... with a peak once in a while..and i lose abt 1 to 1.5% per hour
with wifi off i get about 3-5ma..
i dont use mobile data much so cant really comment on that..
try calibrating your battery and try changing the scan interval in the build.prop... i normally keep it at 90...
i never used any battery saving apps, so cant comment on their performance either...
go to wifi advanced settings and untick Best Wifi Performance... that also helps a lot!
hope you get your problem sorted
Thank you all for the help
The issue was not with gingerbread...I just left my phone one night with wifi turned on and lost 40%.But still when I was on Froyo wifi wouldn't loose so much battery.Now I loose almost 2-3% every 15 min if surfing the web with wifi.
And about changing the scan interval in the build.prop...How can I do that?Do I need root?
I'm also having battery problems, but mine are a little bit different, if I'm on wifi it uses between 3 to 5% with a peak now and then. if wifi is off and I'm on 3g, it's between 5 and 500 ma and you see only peaks if you check currentwidget. anyone a clue? working on ARHD 5.1.6 now, but problem was there since version 3
I have battery problems also, my battery dries after 1 day of use. For example this morning, I unplugged my phone full from the charger at 10 am. I went into town, listened to about 20 minutes of FM radio. When i stopped the radio, I still had 98% left of the battery. OK so far. After, I talked for about 5 minutes, sent 4 messages and played for about 15 minutes. I arrived home at 2 pm with 75% of battery left. That is 25% in 4 hours.
I was on 3G, but with Mobile network off. BT, WIFI, GPS off. A few days ago, I tried running the Battery Calibration app, but seen no improvements so far. My phone is routed, 2.3.3 and has Android Revolution HD 5.0 RC1 ROM .
I expected the battery not to last for long, but this is ridiculous.
Help me, please!
I don't know if that will help, but I sometimes switch to 2G networks as HSDPA is using quite a lot the battery.
I have a DHD running 2.3.3, and it's definitely the mobile standby bit which is first in the battery use screen (33%). It was true before 2.3xx but now it's a bit more - annoying in other words.
I have to admit, having to switch to 2G networks is a bit of a pain in the *ss, so I'll check if juice defender give me some good results tomorrow and will post a feedback there.
Maybe try AR 5.1.6. + he recommended radio. It works wonders. the battery life is improved a lot...
malik
Juice Defender works very well - with basic settings I still have 35-40% of battery by 7pm.
furstrated with the battery life...
hey guys,
so this is my first post and all i've done up until now was to read... i'm afraid not real solution has come up.
i have:
Leedroid 3.1.2 with the recommended radio and i ran the script for Full Wipe 1.5 and cleared the battery stats, i did a fresh install and then didnt restore from backup - just installed everything from scratch. i hoped it would be ok, but when i woke up to check the current widget log, i saw that in the middle of the night he climbed to 150mA and stayed there draining about a 1% of battery in 3-4 minutes (!!!)
what can i do? 'where is my droid power' shows only HTC Sense at about 3.8%
please please help... thanks!
Hey guys,
I've had my DHD since November, probably been modding since, like, March.
Anyhoo, I've installed a variety of different radios and a hell of a lot of ROMs including ARHD, RCMix, MIUI, Virtuous Unity, CM7 and I'm currently on Blackice, but through everything I hear, good or bad, about battery life, it just...doesn't change.
VU and BlackIce supposedly have phenomenal battery life after a day of medium use, but my battery has been the same on every ROM. I've calibrated, deleted battery stats, etc. but it just doesn't improve. Only once was it really bad, I was losing like 10% per hour when connected by wi-fi, flashed a new ROM and it went away.
Why is it that my battery life just isn't changing at all?
If you're dropping only 1 percent every two hours then you shouldn't be all that bothered when on standby.
1% every 2 hours in standby is pretty good, my battery is far worse than that I'm afraid. It's an undersized battery for this 4.3" display imo, I wish they'd put a bigger battery in there!
What have you got set up on your phone in terms of synch, widgets, things that poll the CPU?
Have you ever restored system data via Titanium or whatever across different ROMs?
What are you losing per hour on standby with BlackIce at the moment, dude?
I'm on BlackIce and I get pretty much the same as most others: 1% per 1.5-2hrs.

No, Auto-sync off, but periodic background syncs (every 3 hours) of 3 sync accounts and Wifi always on.
I've not used Auto-sync since the first day I got my phone. I didn't think anyone used it these days, coz it annihilates the battery!
its depends if u have the screen on all the time,the things that batteries varies only on the time that ur phone is idle,and ofcourse with auto sync on and background application(SURE U CAN'T LIVE WITHOUT THEM) ,try to use a rom with uv included,currently am using evasence 2.3 and my battery last for tow days
My battery usage on ARHD rom is about 1% per 1,5-2 hrs. No autosync, but mobile data allways and soetimes wifi on.
And when the autosync is on the drain is much more. But who uses autosync anyway?
This night i've tried to disable data connection, i'm on RcMix Runny V3 with LordClockan Kernel and killersloth UV, battery dropped 5% in 7hour!
In the daytime i've always sync on (like hard.rocker said!!) for IM app and email app and with very heavy usage i cant reach half of a day...
In GSM only mode i usually can handle 19/20 hour of usage... i'll test the duration after UV!
Sorry for bad english!!!
I've reflashed my ROM this time without restoring any data from previous ROMs. I barely ever use mobile data, only wi-fi for maybe 8 hours, and while I do have auto-sync on the only accounts I have in Accounts & Sync are Google (which isn't synching my gmail for some reason...) and Facebook.
I'm running stock Rom etc. With hsdpa/3g on, heavy use gets half to three quarters of day, turn hsdpa/3g off, drops like one percent every 4 hours. Annoying having to turn internet off though.

Try switching to 2G.
Or better yet, try Tasker and create a profile which switches you to 2G and disables Mobile Data when you are on Wifi.

When I got my Dinc2 last week I automatically ticked the "Best WiFi performance" checkbox in the WiFi advanced settings, without thinking about it much. But then I realized it must be the WiFi setting that's draining my the battery so quickly overnight. As an example, during a 7-hr period last night with hardly any email polling, my battery drained from 50% to only 15% capacity (that's about 5% per hour). My wife's original Inc only dropped 2-3% during the same period, sitting right beside mine. And you could see the graph in my battery stats take a constant straight-line nosedive from the moment I turned the WiFi on. So I unchecked the "best performance" feature immediately this morning, and will see how the phone performs tonight without it.
What does this "Best performance" setting do? Is it only necessary for something with a high data need like VoIP or media streaming?
Thx,

I wonder if it decreases the wifi scan interval? That would certainly explain the battery drain.

Right you are. And because my Dinc2 is only a week old, it's still running the stock 2.1 Sense rom on Gingerbread 2.3.4
Tonight I'll start some testing... one night with the "standard" performance WiFi, the next night without any WiFi (or 3g) on.

So the results are in. Over the past 3 nights, I let my phone sit overnight in different wifi configs, to get an idea of the effects of the different WiFi configurations. In each case with the same minimal email polling and no other main apps running. It's a brand new phone, running 2.3.4 and Sense 2.1 (I haven't rooted it yet).
It turns out that Sense's "Best performance" WiFi setting eats up battery at a MUCH higher rate than anything else, approximately 10x hungrier than the regular wifi settings or no wifi or 3g at all. And the regular WiFi setting uses virtually no battery when there's nothing much downloading. Here's the raw data:
Best performance WiFi > 7 hrs produced a 35% drop in battery (5% per hour)
Regular WiFi (Best perf unchecked) > 10 hrs produced a 2% drop (0.2% per hour)
Both WiFi and 3g off > 7.5 hrs produced 2% drop (0.26% per hour)
So it's the regular WiFi config for me; YMMV.

Hmm... It has been a while since I ran stock, so I am not sure what 2.3.3 said, but on that ROM, I found that the settings performed similarly to the AOSP Android Wifi Sleep Policy. So Maximum Performance = never shut wifi off and the normal setting shuts off wifi when the screen is off. I never ran stock 2.3.4, so not sure about that one. On 2.3.3 I always had mine on Maximum performance because I use a lot of background data and having wifi on the whole time uses less battery than all the 3g would use overnight.
So, unless something changed, Regular shuts off wifi with the screen and max performance keeps it on all the time.
And stock I would only drop about 2-4% overnight with wifi on max and everything syncing. So unless something changed to 2.3.4, then something is either over-using your wifi because it is available or there is something else at play.
At any rate, everyone's usage is different, so use what works for you.
Actually I have the sleep policy set to never turn WiFi off and hand back to 3g... mostly because I use the "Unlock with WiFi" app and I don't want the phone relocking just 'cause the WiFi went to sleep. So Sense's "best performance" setting must do something else.
Who knows; I don't need better WiFi throughput so I'll stick with the regular WiFi settings which don't drain battery juice hardly at all when you're not actively using it.

Hmm... Must be a 2.3.4 thing. I don't remember it from 2.3.3. Maybe I just forgot about it, but I don't remember seeing it because I would have enabled it. I need some wifi boost at times. I am wondering if it is setting the wifi to keep it at max tx/rx power... Maybe if I can get some time I will try to see what I can find in the code.
---------- Post added at 10:49 PM ---------- Previous post was at 10:38 PM ----------
Well I checked the xml real quick as I am not at a workstation with all my software on it and 2.3.3 had it too. I always set the sleep policy right away, so it is possible I just set it and forgot about it.
I will see what I can drum up about what it does, as I am curious. If it is some sort of power boost, maybe it can be adapted to AOSP.

Thanks for sleuthing...
So -
I just discovered this setting. I was downloading some google music after returning to Andy Bones Stock Rom - and figured I would give it a go.
When I get home, I am gonna use the speedtest app to see if I can actually move data faster or not. It seems like that would not be true, but who knows.
The setting DEFINITELY crushes the battery. It seems to be really fast DL (especially for pulling a large number of music files) but... I have no empirical verification for that claim.
Testing to come.
I found I average 1-2 mbps faster without it.

I have a rooted G2/Desire Z. What are some ways that I could save battery? It seems it takes only a few hours for it to reach 50%. Granted the phone is now >2 years old and the battery is probably aging. I've done all the basics such as screen brightness set to auto, dim after 30 seconds, etc. etc. etc. What more could I do?
Alternatively, are there any apps that can control the phone/cpu to work a certain way to save battery life?
Thanks

Granted the phone is now >2 years old and the battery is probably aging. I've done all the basics such as screen brightness set to auto, dim after 30 seconds, etc. etc. etc. What more could I do?
Alternatively, are there any apps that can control the phone/cpu to work a certain way to save battery life?
Thanks

Setcpu,set screen off profile to lower clock..freeze some bloatware up..and also try v6 supercharger

Easiest way:
Uninstall fabebook app, flash a sense rom where you can access most fb functions without the app.
For real, my battery life went from about 10% an hour to 4% an hour on average.

Honestly, way number 1 is to get a new battery. Old batteries just start to drain much faster as they get older. Pick up an Evo Design 4G stock battery for a nice boost.
2. Turn brightness off auto and put it as low as you can handle. Keep a brightness slider on your notification bar for those situations you need to turn it up quickly.
3.Turn everything that "syncs" off of push and set it for 1hour+ intervals if possible.
I have had great standby time using the OC daemon that is packaged with the mimicry ROM as well.
There is this trick that helps. On a monthly bases drain the battery and re-charge with the phone on ie also a good Rom an a good radio version like .19 will keep your battery good don't use lots of ram manager apps and bettery saver apps the run backgroung processes that drain your battery fast

With 2 year-old battery there are only 2 options:
1. Replace the battery
2. Buy a new phone

^This (regards to #1), and working batteries are rather cheap, the fat one I got (3500mAh) was 9$, but you can easily get a stock replacement of the 1300-1500 range to fit with the default battery cover.
Far as tips, rooted or not:
1) Screen to automatic, or avoid 'full brightness'. Your screen consumes the most of your battery, automatic or lower brightness can improve the life significantly. This is the big one as your screen will typically be 80-90% of your battery life.
2) If you are near wifi often, System Setting -> Wifi -> Advanced (via menu) -> Sleep profile to always on. This will set it so that the wifi connectivity is always on even with the screen off. A connected good wifi connection uses far less battery than your 2G/3G data constantly searching for a good or better data connectivity. Simply turn off wifi completely when not in an area with wifi (or if you're driving around).
3) Avoid unnecessary applications. Don't use twitter? Freeze/Disable the application under manage app or under Titanium Backup (generally it's not good to 'uninstall' an application completely if it came with the rom).
4) SetCPU with profiles is one way to do it, unless your rom comes with a CPU Daemon already (ie: mimicry with virtuous OC Daemon), When setting a "screen off" profile, try not to go below 768mhz for the maximum, as going with 384mhz for example may be too slow for the phone to effectively wake up when a call or notification comes in.
5) You can use an app such as Tasker (not to be confused with task killer). Where you can assign automatic tasks, such as automatically setting Radio to 2G when connected to wifi (some roms like AOKP do this automatically under power control), or other tasks depending on the circumstances.
6) The first time you get a new battery, make sure you leave it on the charger for a good 5-6 hours so that it accurately 'tops off', the phone won't know accurately what's 100% and what's 0% until it has been fully charged (least 6 hours minimum), and fully drained, after which it'll more accurately report your battery % as it's used and will have more accurate usage stats.
7) If you're a T-Mobile subscriber, consider the 26.13.04.19 radio as well as the T-Mobile Wifi calling app, wifi uses less power in the long run than your radio via cell towers. If you'll be in a location that has wifi often you will benefit from this over not using Wifi Calling. (The main downside is you cannot currently send/receive MMS over wifi calling, but Calls and SMS[txt] work fine). Even if you don't use the wifi calling app, the 26.13.04.19 radio provides better battery life over the older one.

Course it helps to clear battery stats before performing this task so that the OS/Battery-Stats records the new maximum and minimum values of the battery. Though you don't need to do it monthly, I would say closer to 6 months would be appropiate if you don't want to make a monthly habit of it.
You mainly only do this on account of battery aging (over time the battery will not hold as much charge as it once did), You normally know if you need to do this task again if it appears to be on 98% or 99% forever never reaching 100%, meaning that the battery is no longer able to hold the juice to provide the former-maximum mV value, re-doing the battery stats simply makes the new maximum marked as 100%.
PS: Strip419, on an off-topic note, I tend not to 'thank' people who ask/beg for it. If your post is worthy of thanks, they'll be clicked on their own accord.
OK MAN I'LL KEEP THAT IN MIND

Best rom I've ever used for battery life is EliteMod. That rom did something crazy, cause my phone lasted for days before it need charging, and I use facebook and all that good stuff. It's not as fast as other roms, but battery life is certainly the best on that rom.
Also yea, before with stock battery my phone would last a day at best, and now I have a 1800 battery that makes it last for 2 days easy. So if your phone is at least 2 years old, get a new battery. They're dirt cheap on Ebay or Amazon. The phone comes with a 1300 stock.
simply change for normal use 2G instead of 3G.
A couple of questions--I'm using EliteMod CM7

My Advanced settings don't look quite like yours, alas. (I'm using EliteMod cm7.) The section is entitled "Wi-Fi sleep policy, Specify when to switch from Wi-Fi to mobile data" and the only options are " When screen turns off," "Never when plugged in," and just plain "Never." I assume that the "Never" option, that is, never switch from Wi-Fi to mobile data, is what you mean...that is in any event the default (set by this particular ROM?)
But my problem goes beyond not quite understanding the semantics of "Never" (off?) vs. "Always on." What I continue to find odd is that my highest battery usages, at least according to Battery Monitor Widget, are never the screen at all; rather they are cell standby, Wi-Fi, phone idle and Android System...Display is down at 6% just now, for example (and I've been up for hours, have read the news on the phone, emailed, texted, etc. This is on EliteMod only, btw, I used Flinny's latest build (.94?) for a few days recently, and while battery usage was worse, at least the display was at the top of the list, where it (presumably?) belonged.
I have all the latest and greatest tweaks from the the forums (for cm7 roms, that is) the .19 radio and sd-ext and all ext4 partitions. Am running the generic 3500mah "fat boy" battery...drained and refilled several times, all according to instructions...mine only shows maybe, umm, 2300 or so mah, but that's not the issue for just now...it's why my usage looks so odd, and how to fix it, if need be.
thanks to all,
p-d
oh yeah. I have long used (pre-rooting) Lookout and Pouzerate's Green Power free apps...have now turned them off (well, uninstalled them, in fact) just to see if, indeed, battery helper apps make things worse, running in the background... any thoughts on that topic would be welcome as well.
