Sorry to start another thread on battery issues but I was unable to find a scenario like mine.
Hey everybody, Im new to the android scene, just got my vibrant less than a month ago. Before that I had an Iphone 3g. So far I like the phone but the battery life is horrible. When I surf the internet on wifi or 3g I noticed that I use like 3-5% in a matter of 5 mins. Is this normal? I consider myself to be a light-moderate user and have been getting and average of 12 hours or so on my vibrant. Also if it makes any difference when my phone is idle or being used my temperature runs around the high 80's low 90's but when being charged it drops to the low 80's or high 70's. What is going on? How can I get more 20 hours on my phone? With the iphone I used to get an easy 15 hours and still have like 40-50% remaining.

When I first got the vibrant, it had pretty bad battery life, I would lose like 25% while sleeping 8-10 hrs. So light usage would be like a day. Slowly I started to get longer battery life (2 days on light usage). Recently I could get up to like 3.5 days on real light usage. After updating to JI6, max I can get now is like 3 days. I didn't really do much and I tripled my battery life by just giving it time.
Thanks burntrat I guess ill be patient. And I must mention that I am running stock.i was just worried because my battery temperature gets colder when charging and warmer when idle or running.

Hey burntrat or anybody, has your battery ever acted sort of schizophrenic on you? I mean one day I leave it on standby and its drains like 1% in 7-10 hours another day I leave it on standby and it drains 18% in about 4 hours. Whats going on?

My battery has been draining inconsistently lately. It drains faster in the 50-100% level. Under 50%, it feels like it drains slower while doing the same stuff.

if your phone is draining a lot during standby or sleeping. There may be a rogue app out there or an app that didnt shut down properly. (I guess that would mean a rogue app)

@aamir123 and burntrat: maybe you guys need to calibrate your battery? Also the stock rom usually has a lot of bloatware running in the background. Flashing a custom rom oughta do the trick.

How do you recalibrate the battery?
Sent from my SGH-T959 using XDA App
Try this. Download the system panel app from the market. You can set it to monitor your system and it will chart what applications are running and how much they are using the cpu. If you find you have some unnecessary bloatware running in the background download titanium backup and freeze those apps.

There are a lot of different ways mentioned in different forums. Try this:
Let your battery drain all the way to the point when it turns off by itself.
Charge it while its off until its full.
Unplug it, turn the phone on, then plug it in again.
After it reaches 100, unplug the charger and turn your phone off.
Once off, plug it in and let the charging complete.
Once complete, unplug it and turn the phone on. When everything has loaded, turn the phone off (note: no charging involved in this step.)
After it turns off, charge it one last time until 100%. After this, go into recovery and clear battery info (or cache, I forget). There you go
Oh, and its better if you don't download too many apps that monitor battery usage, cpu etc. cuz they will contribute to the battery consumption.

It isn't a good idea to let your battery drain all the way to zero since it is lithium ion. I think skipping that part and just charging it when it's on to full, then off to full, then on to full, then off to full and then wiping battery stats would suffice. Also you need to have clockwork recovery to wipe battery stats.

When the phone turns off by itself, the battery still has some juice left in it to prevent it from losing the ability to charge, if that's what you meant by not a good idea cuz its lithium ion. If thats not what you meant, then please explain why.

Agreed. In my case, I barely lasted 12 hours on moderate use with any of the JI6 2.1 ROMS (Eugene's, Bionix, Fusion, etc). I think after I updated to 2.2, all of the ROMS have been giving me 18+ hours on moderate-heavy use no matter what modem or kernel I use.
So where is the "unique" problem?

Hi folks, I'm running CM6 8/26 nightly with Snap v7.4 kernel with SetCPU set to conservative on 998mhz max and 245mhz min. I'm getting horrid battery life and I think I'm doing something wrong: I wiped battery stats in Clockwork and now my battery SUCKS. -.-
Question is, what its the proper way of calibrating an Evo battery? I've seen the official HTC response but I don't think it's going to make a difference. Isn't there another method that requires you to drain the battery? Any info will be appreciated I've been looking at forums all day.

You can't just wipe battery stats - there's a process to go through. What you're referring to is Cyanogen's battery recalibration method found here. Read through fully before wiping anything.

Actually it is almost as simple as wiping battery stats. That command he gives is what the wipe battery stats command in the recoveries do.
1. Charge battery to full (where it's actually 100% not green light.
2. Boot into recovery wipe battery stats.
3. Fully boot into os then unplug charger.
4. Leave unplugged until the phone shuts itself off.
At that point you should be calibrated.
On a related topic, the Battery Graph app available in the market also has an option to wipe battery stats from within the OS, doesn't it? Might save having to reboot into recovery once you're charged up.
It's a lithium battery. You can't condition it. Just use it as normal and ignore all these placebo effect steps.

They're not calibrating the battery. they're calibrating the phone to know when the battery is really fully charged which, until you do this, is not the case when the charge light turns green.
Regardless, none of this worked. I've quit all services, no sync, auto brightness and wifi and I'm still getting horrible battery life. SetCPU is set to conservative. It's BULL**** my display is on for thirty minutes and the battery dies 20%. I played a game on my friend's iPhone 4 for twenty minutes and his battery barely died 3%. This is really unacceptable and I'm probably going to return my Evo or sell it if the battery life doesn't get better soon from these methods I'm seeing online

Crazy man, maybe something happened cause that is pretty bad.
Have a backup to go back to, prior to this happening, to see if it reverts back to normal?
Naw nothing happened to my phone...... All of us Evo owners should be able to use this beautiful phone with all of the features at max without the battery going to ****. My phone has behaved this way since unboxing. I'm not a big fan of the iPhone 4 but I will give it props on battery life. I have yet to try the longer HTC method but it seems kind of pointless.....
Sent from my PC36100 using XDA App
If it has always been like that then you may have a bad battery, if it started after you wiped the battery data then it is just showing you bad readings.
You should be able to get a good calibration if you reset your battery data again, maybe try through your recovery if possible, and then fully charge it with your phone turned off. Once it is charged you can either use it normally till it dies or you can tether, use gps, watch youtube, etc, and drain the battery down. Just make sure you go from a full charge to the phone shutting itself off without plugging it in to anything. Do that charging with it off and using it till it dies two or three times and your battery stats will be calibrated.
When I did this to mine it showed my battery at 0% for at least half an hour before it finally died, and that was with me listening to pandora and browsing the web.
Edit: FYI, the Evo's talk time is usually between 6.5 to 7.5 hrs, the iPhone 4 is around 7 hours also. If your battery is not lasting that long you need to take it in to sprint and have them give you a new battery.

HTC's method worked wonders for me. i'm a heavy heavy HEAVY user (no, not fat) and I get a good 10 hours with everything besides 4g on plus surfing, gaming and tethering for SEVERAL hours. For all that I do on my EVO 10 hours is HUGE. If I have a moderate day of usage (maybe a little more than moderate for the average user) I get around 19 hours.
Btw none of this will help if you are getting near 100% awake time. If that's the case you need to find the software causing that first.

With phone on, charge until green.
Unplug and turn phone completely off.
Charge phone until green once again.
Unplugand turn on. Once phone had turned completely on turn the phone back off again.
Charge until green one more time then unplug and turn on and you're done!

Hi,
I unplugged my phone this morning around 9 A.M, and sent about 50-100 texts today, and right now at 5:35 my phone is at 33%. The only thing that is running, is ADW.Launcher, and I've done LIGHT Twitter/Facebook checking throughout the day, maybe about 2-3 times each. I have Beautiful Widgets, but it's set to update every hour. I haven't talked on the phone at all, and my brightness is set to auto. My wifi is off, and I made sure I don't have GPS or anything on. What's killing my battery? My BB's battery life was 1000x better, I shouldn't have to baby this phone to have it make it through the day.
I'm running JT's Clean D101 rom, and that's it.
Edit - 32% now.
Get "OSMonitor" from the market (its free) and it will give you a real time display of all running processes and cpu % for each process. To make it easier to watch list open options in OSMonitor and sort by load and make sure order is checked as well. And watch the list for a couple of minutes to see the offender that is hogging the cpu. I've had problems with the xda app and I seem to be the only one that has it hammer the cpu after closing it so I always have to kill the xda app in task manager after using it or else it will ride the cpu between 8-20%.
My typical idle cpu usage is about 2-5% not including the cpu usage of OSMonitor itself.
good day.

Thats about normal time for a Smartphone. If you average that you used 66% of your battery in 8.5 hours, then its safe to say your battery is averaging 12 hours a day. Also, most of your battery will go to your display, and if you texting all morning, your display is going to be on all morning.
It also could be that your in an area with bad signal. Your phone is going to pump juice to try and keep signal.
As far as BlackBerry gos, its not nearly as smooth and capable. I could argue my flip phone from high school lasted four days without needing to be charged. Android is in an entirely different class than BlackBerry.
Is there a definitive process for conditioning or reconditioning the stock battery? I'm on my second fascinate(vzw replaced first one basically because of my frustration with the local vzw store) & I've noticed a big difference in battery life between the 2. First one was completely stock with adw launcher only & it got 16-20 hrs between charges. This one is rooted, some bloat removed, and I only get 8-10 hrs. Using os monitor to look for cpu hogs & so far no improvement. Put all my bloat file extensions back to stock in sys/app hoping to impact erratic charging cause it all started after root. Any ideas?

I'm no expert (standard disclaimer) but I don't think it's a matter of calibrating the battery as much as calibrating the software.
Power the phone down
Charge to 100%
Boot into CWM
Wipe Cache
Go into Advanced, and Wipe Battery Stats
Pull the battery, reinsert, and again charge until have 100%
Unplug, reboot, and run the phone in whatever your normal use is until you get as close as you can to a full discharge
Again power down and charge to full
As I understand it, this process allows the software to correctly read the true charge on the battery. if anyone sees any flaws with this, or anything incorrect in my information, please advise.
Are you using a Live wallpaper? I noticed an increase in my battery life after I turned it off, which is kind of stupid because it should only use CPU cycles when the screen is turned on.

Hey guys,
Just created this thread so we could all have our battery life info in once place and keep the dev thread from getting cluttered.
Please post the following info:
1. Standard or Fully Loaded version
2. Total hours unplugged and percentage
3. Details (percentage and time) for each service
4. And any pertinent details such as apps used (juice defender), or extended batterys
Also, please don't forget to calibrate, airplane bug fix, and kill that drm.
Ex. (will edit with final time)
1. Loaded
2. Total - 8h50m @66%
3.
Display - 55m 78%
Cell standby - 8h50m 9%
Wifi - 6h40m 7%
Phone idle - 7h54m 4%
Voice - 1m 3%
4. Juice defender, setcpu @ 100/1000
Ideally we want to wait for a full drain to post stats but this is just an example. Thx guys looking forward to seeing what you all are getting.
Just installed it will get back to you in a couple of days after recalibrating my battery.
Btw, i hear Juice defender does more harm than good...

Battery drain
Hello everyone, noob here. I can't post in the development forum on this but it pertains to the battery and charge to a degree. Maybe someone here can help me in some sort of way.
I rooted and flashed the SyndicateROM Frozen yesterday, used it all day and never a hiccup. This thing is lightning fast and props to the dev's but here is the only issue I found. This morning after waking up I noticed the phone was stuck on the ACS android startup icon. I plugged in to charge last night and it's like it froze the phone when it reached full charge. Anyone else experience this?
Thanks for any help that I receive.

I think I read in the dev thread that it's a known problem with the kernel? Or maybe it was the rom... or CWM? anyways the dev's know about it. Just don't charge your phone when it's off.
Battery for me seems to be a lot better than stock, but I'm always charging here and there... today I'll let it run without charging for 4-5 hours and I'll report back. Using a lot of setCPU profiles.

Are you charging it with the power OFF? Lots of people were posting issues of freezing when charging with the battery off --- and I think the probs are related to CWM -- not the ROM. Only charge while the phone is on -- and you should not see problems.
I put on to charge with the power on last night because I had set the alarm to wake me up and it never did so that is when I noticed it. I don't think I've ever charged it with the power off, even when it was stock.
Maybe the dev's will come up with a fix sometime in the future. As for now, I'm happy as hell 'cause this ROM is great.

Did this just happen once? If it doesn't happen over and over, I wouldn't consider it a bug. I have only heard of issues like you describe with the power off.
I'm looking at 12 hours on ACS Frozen on average. I haven't even gotten close to the rumored 30 hours with "heavy use" I think my use has been moderate. My battery use log only only lists display 98% and cell standby 2%. This confuses me. I do more than sit there staring at my homescreen.

How you use your phone makes a difference and while 30h is possible, I don't see it happening with heavy use unless that is little display use. Below is my most recent "heavy use" run. Basically tried to use the phone all day, xda app, browsing, mainly wifi, 0% screen brightness.
1. Loaded
2. 8h7m @5%
3.
Display - 5h33m 95% <- serious display use which kills the phone quick
Wifi - 4h56m 2%
Cell standby - 8h7m 2%
Voice - 4m30s 2%
4. Setcpu @100/1000, juicedefender, 0% brightness
Pretty good considering the insane display usage. With normal use I get over 20h so that just shows how fast it kills your battery. Going to do an "extreme" run next to include heavy cpu use (play emulators all day haha).

Pretty good considering the insane display usage. With normal use I get over 20h so that just shows how fast it kills your battery. Going to do an "extreme" run next to include heavy cpu use (play emulators all day haha).

You did that with a standard battery? I haven't seen anyone post more than 4 hours of display "time on". That's impressive. Maybe I should try 0% brightness. I have mine at 25%. Are you on "Conservative" on SetCPU?

I'm looking at 12 hours on ACS Frozen on average. I haven't even gotten close to the rumored 30 hours with "heavy use" I think my use has been moderate. My battery use log only only lists display 98% and cell standby 2%. This confuses me. I do more than sit there staring at my homescreen.

The 98% means that 98% of your battery use is coming from the screen. Click on where is says 98% and look at see what the use details are (the "time on"). Generally, most people are getting less than 4 hours of display time on with a single charge. The explanation is that some people stretch 4 hours of display time over 30 hours of use. In other words, the people who are getting 30 hours of use only have their screen on 10 - 15% of the time (or less).

Yes, using the standard battery. Setcpu is on conservative. I always use 0% as it looks great (kick it up tp 25-50% outside). I think I was able to get that long of display use due to minimizing cpu usage and other services. All I did is browse in dolphin and use xda app. And, that was pretty much all on wifi. Only change was the hour I was at the dog park on 3g and I recorded a 5 min video.
I bet my gaming session tomorrow will kick it down to ~4 hours
With phone calls, texting, and music player, I average between 16-18hrs. If I start to web browse or watch videos then about 8-12hrs. Very impressed with this ROM to say the least.
1. Standard
2. 31 @ 5%
3. don't have that it was yesterday
4. standard battery, auto brightness, overclocked to 1.2, wifi on when I was at home and 3g at work.
I calibrated the day after froyo dropped. I didn't do the airplane thing and I thought drm was not in this rom. So in other words I didn't do any fancy stuff.
I will note today I tried 1ghz (which is undervolted) with 4G on all day (I have a repeter on my roof at work) and after 14.5 hours I am at 30% with about the same concistancy of usage as yesterday.
Edit: I only have 1 gmail syncing right now. We will see if I get these magical numbers when I put my other 2 gmail accounts and my 3 actice sync exchange accounts on Monday.

I'm getting mixed battery life. The first day on the rom/kernel I dropped down to 79% in 9 hours, with medium use (no web browsing). I was getting 1% drop every 1-2hrs, and thought it was amazing. Today I tried to be really conservative and didn't use it at all and it dropped 4-5% every hour WHILE IDLE.
Anyone else experiencing the same problem? It seems to happen after a reboot to be honest.
NOTE: If I disable data network mode, battery life is amazing,
I'm not sure about my battery life. I charge mine differently than the average person though. I charge it at work and leave it in my desk, because I use it a lot during my lunch break or whenever I get any downtime. When I get home it's usually at about 70%, and it remains unplugged until the next day. I used to have to charge it at home and at work.
I was under the impression that the battery drain issue was fixed with new sc 2.9.2. Anyone else still having issues?

Im only having problems with voodoo kernels. Flashed ec10v last night and had same issue. disabled voodoo and flashed back to eb01. did full wipe this morn and installed sc 2.9.2v and im back to same battery issue. its irritating.
No issue for me
I am actually seeing much better battery drain... I am on SC2.9.2V
im unplugged almost 4.5 hrs and im at 95% still....
sigh... working on battery calibration now. i have to leave for work soon so w/e i do it has to be now. lol. no comp access at work so i cant odin cwm if i break it. might just flash back to sc 2.9.2nv till i have time to play.
My 2.9.2. dropped 5% in 15 minute idle state.

I feel your pain. In my case, and maybe yours, I think the culprit is the horrible coverage verizon gives me.

Does your battery drop to 0 that fast?
I have had a time where by battery dropped 15% within 1-2 hours, but then I was stuck on a certain percentage for hours.
Hello, I started a thread 2 weeks ago and it has some good info there. Take a look.
I update the OP regularly adding post made by others. No one has posted anything in a week. If you find how to fix your problems please post it there and I will add it to the OP. Its up to everyone to keep that thread alive.

I've had issues as well. Mine are related to GPS wakelock. Every fresh boot I will consistently get a partial wakelock of 100% because of the GPS. Simply opening Maps and closing it will force the wakelock to release.
I'm curious as to why others aren't having this issue, yet some of us are?
I've tried the EB01 modem as well as the DL09 modem and its the same results. Aside from this, battery life is great...

When you say 'idle' do you mean like zero apps running (like stopping everything running via a task killer). Then what,, like keep the phone's screen lit up by not letting it sleep and monitor the battery drain over a period of time? I'll have to try that and see how mine does. I'm guessing mine will prolly drop 15-20% as well if I have the screen lit for a solid hour.. hmm
I didnt really think mine was working 'bad' though, I just figured thats about what these batteries in these could do. I can make it though a day without a re-charge but I admit I have to budget my usage of the phone thoughout the day.. not using it for long solid periods of time and such.. If 15-20% an hour drain would be considered 'bad', how much should it drop in an hour to be considered working 'well' in your opinions?
Well I spent all day charging, using and then recharging my phone. it died in about 5:45 hrs of med to heavy use. I used the method outlined in this thread. http://forum.xda-developers.com/showthread.php?t=987529
I lost 5% battery in 45 min this morning which would have been nice but it was idle in my pocket. :-(
I gave up... reflashed 2.92nv and im checking to make sure its not having same issue.
If anyone has more suggestions there are now 2 pages i found for this problem specific to the facinate.
My battery is pretty decent after clearing battstats. Heavy use I'll lose about 13% per hour. Idle is decent, 3-5% per hour.
2.9.2 ec10voodoo
Ok I did a little test with mine - I set my LCD screen timeout setting to 10 minutes, turned my wifi and gps off (left the cell radio on), killed all apps that were running in task manager. Then I sat the phone down on my desk with the screen lit up and tapped the screen every 8-9 minutes or so just to keep it from going to sleep for one solid hour. I didnt do anything else with or use the phone in any way during this time. My battery dropped 18% in one hour. Think I'll try the batt stat clear procedure and redo the same test and see if its any different.
Mine is horrible. For some reason, it drains in proportion to my use. If I use it constantly, and hardly put it down, I'm lucky to only get 6 hours out of it.
I don't get decent life unless I put it in airplane mode, turn off rotation, and don't use it. Then I'm good for
16 - 18 hours.
WTF¿

I can understand getting 6 to 8 hours if your a heavy user. but Im only concerned with my idle battery use. Juicedefender help some what. you can get it on the marketplace.
I'm still having the same issue with the nonvoodoo version. I'm still not sure how some users are getting over 40 hours of battery life.
as far as I can tell recalibrating my battery had no effect on the battery life. I plan on trying to recalibrate 1 more time in case I messed up the process. I will post my results in a day or 2. good luck to the rest of you. if you find anything out that may help me or anyone else please post it here

... and from what I'm reading, trigger gives great battery life. So how do I see what has been eating my battery life up? For instance, I unplugged 40 minutes ago and I am down to 91% already.
The regular option on the phone doesn't do a great job of troubleshooting this issue and just says "Display" and "Cell standby" as the relative battery use culprits. I figure, though, that this must be something I downloaded that is killing the battery. I love the ROM overall, but if this battery issue can't be resolved, I need to find something else quick. I'm a slave to a charge port.
Thanks.

Have you tried conditioned your battery by wiping your battery stats.bin? Why didn't you flash the newest Trigger?
Yeah, you need multiple cycles for battery to be even close to accurate, and you should recalibrate.
Are you using other kernels or themes?

Let your phone die wipe battery stats in recovery mode. charge to 100% then use the battery calibration app from the market and re-calibrate the battery. I always repeat the process. Sometimes when flashing new ROMs your batterystats.bin can get a little funky so I always do this after flashing a ROM and my battery works great.
Definitely check the Kernel and Modem your running if there not the ones that came with Trigger than that could be causing your problem as well.
From what i have got from prior experiences. Using odin to go to stock as if your phone just came out of the box and then flashing removes all the old files. When i did this i went from getting almost 10 hours... now my phone gets 17 normal and if i dont use it as much as a normal day it iwll hit 24 hours no problem.

This post (http://forum.xda-developers.com/showthread.php?t=806022) is saying to wipe battery stats at full charge... So what is it?
And why didn't I flash the newest version? It was when I flashed it.
What was the use in the 40 minutes after charge? I could see that if you had screen brightness high, and lots of wifi surfing or video use. I downloaded an app called 'screen filter' and it lets me lower the brightness lower than stock and I have noticed significant battery length increase since use. The stock dim options are not enough. Its still too bright and a waste of battery.

Both. I wipe mine at 0 and at 100 but once you wipe make sure you fully charge without interuption and vice-versa

same here, and i suggest you do the charging during night when your sleeping, so then there'll be no interruptions, like having to reboot for some odd reason etc. That can disturb the process of recalibration/conditioning.

Pretty much nothing... Maybe looked at Facebook once and replied to a text?
So I drained it, wiped the battery stats, then looked at what it was doing - probably 1 minute after it was totally dead and wiped. The screen said it was at 14% already.
In less than a minute - 14%...

Let it die again and wipe again. Your stats are off from the flash its normal. Just let completely die wipe charge wipe repeat. It will take a couple times normally to get back 100% right

I used to chage my battery overnight with good results but since going to gingerbread it usually drops from 90-100% whne unplugging. was reading up and found out it's saftey feature created by Sammy.
