After being on the charger after 7 hours as soon as I take out of the charge my battery his down to 98%. I made one phone call of 2 min and 3 txt messages and it dropped another 1 percent. Before this charge I let it fully drain. Anyone?

I experience the same results - When the phone is powered off and on the charger, it only goes to 98% (according to the settings-->about phone-->Status-->battery level
However, if you turn the phone on, and charge, it will reach 100%..
this is insane... my bat is down to 93% and since the first post to now i haven't even USED the phone... i think my phone is not going into full sleep whatsoever. I uninstalled 3g watchdog yesterday as some people mentioned in other forums that sometimes it wouldn't let the phone go into sleep mode. No kidding... that i only noticed this dramatic change in battery time after i installed LauncherPro. when i was using touchwiz on my second charge the phone lasted a full day with moderate use and i didn't even drain the whole battery. Yesterday was the first day i left the battery to die, i had this phone since last friday.
I was experiencing excessive battery use when I was running LauncherPro. I switched to ADW.Launcher and it went away. I also use JuiceDefender to manage connections while the screen is off. It disables data connections and turns them on for 1 minute every 15 minutes to update any data streams & then turns the data connection back off. I can get around 14 hours of light to moderate use now.
to check if your phone is properly sleeping
Plug into charger
Unplug and hit power to turn screen off
wait 5 minutes
hit power to turn screen back on
using spare parts or any other application which shows battery history(battery leftwidget)
check: Running%
It should be less than 10% for someone with a ton of background apps or widgets
It should be less than 5% for someone without a ton of widgets/bg apps
During normal usage it should be within 10% of the screen on %
Exception to this is if using something like music player
100% !!!!! I installed awd bedore doing this test and had no widgets running whatsoever

Is there any way to get this thing to last over 10 hours with moderate/medium usage? I mean I hate to compare, but I was able to use my iphone 4 hard periodically through the day and be at 40% around midnight, but I have to stay using my captivate very lightly after about 10pm, and I usually unplug around 12 to 1pm..
I don't want to have to sacrifice majors perks of why I switched to android just to get a full day out of it. I've tried a lot of the suggestions I'm the forums, but nothing makes a notice difference, or makes it a fame changer as to where I'll get a full day of moderate internet/media usage
Thanks in advance.

Have you tried draining and recharging the battery as other threads have suggested? I usually unplug around 9-10am and I don't get battery warning until near midnight or later.
I keep seeing people complain about the battery life constantly.. but to me coming from my bb bold it seems that the battery is lasting way longer then i expected.. first couple charges i let the phone drain down till it shut off, and then charged it 100%.. its still new to me so im constantly playing with it and changing the menus around.. i try to make sure almost everything is closed when im not using it.. cause im sure that eats battery life..

I did it once, but I booted back up the phone a few minutes after I plugged it in, will leaving it off while it does a full 100% charge noticeably increase battery life?
Do you have widgets updating frequently? How frequently? Maybe just too many updating widgets. I get about 18 hours with the screen on for 4.
18 hours also
I'm getting 16-18 hours of use with about 4-5 hours of screen time. Better than expected.
Today I used my phone as much as I used my iPhone 4 on a regular basis. My phone has been off the charger for just over 12 hours and I have 70% of my battery left.

I'm around that too, I use a black background to save power and I have about 5-6 hours of screen time and I watch a movie on it every day (treadmill at the gym)
I only get low battery around midnight
I use advanced task killer and set it to when the screen is off to kill apps, aggressive mode, I can go about 20hrs before I need to recharge. 5-6hrs screen time.

One thing about android is it has true multitasking. Combined with some apps which do NOT close properly and continue to use up CPU this can drain your batter very fast.
In the battery Info your TimeSpentAwake should be ~ the same as Display on time. If not something is not closing properly. Use OSMonitor to check which program it is and either uninstall it or make sure to kill it with task killer after using.
I have the M110S (Korean Galaxy S - I get 16-18 Hrs with moderate use, but M110S comes w/ 2 batteries so i just swap )
Yeah based on people who are getting good battery life mine is absolutely terrible. I am on my fourth full discharge. I have had my phone off the charger for 2 hours and I'm already at 87 percent. I listened to about 45 minutes of cached slacker radio and like 2 posts on xda app

Just to comment on my battery life. I got my phone saturday (2.5 days ago) and its been on the whole time with medium usage. When I got the phone the pamphlet inside said "fully charge before you turn on" and thats what I did. My battery is at 41% and the only time that I have charged it since is when I am connecting it to my PC for a very short amount of time. I have had great battery life so it is possible. I am very impressed with it.
Yes...my battery life has been good...
Screen brightness all the way down (auto brightness off) *same for the browser brightness
Screen timeout 15 secs (annoying sometimes so maybe 30 secs)
No window animations
Power saving mode off (no point in having the lcd adjust if its already as low as it will go)
I also dont have any widgets that update in the background, however i'd imagine one or two wouldnt affect the battery much
These settings have worked out for me and i use the phone moderately with 2 hourly updating email accounts.....

Battery life for me has been decent. I consider myself a moderate user and I can go from 7:30am till I go to bed at night without dying, but its close. Coming from an iPhone 2G, where with the same usage I could get 2-3 days on one charge, its a little disappointing. But it is what it is I guess. I have heard horror stories of EVO's only going 4-6 hours on a full charge, thats ridiculous.
But what gets me is all this nonsense about fully discharging before charging back up every time. These are Li-ion batteries, they are not Ni-cads, they will not get a "memory" if you dont fully discharge every time. Yes, its good the very first time, to fully charge it before using it, but after that, it doesnt really matter.
Also, one more thing I noticed. The phone will stop charging the battery the second its fully charged. So if your phone reaches 100% charge at like 2am, it stops charging at 2am and you are then going from 2am till whenever you take it off charge in the morning. I noticed this the other day. As soon as the phone told me it was fully charged, the battery icon turned into a normal battery icon even though it was still plugged in. So its possible that the phone is going for 4, 5, 6 hours off charge before you even wake up. What I do to make sure I'm at 100% when I leave, is when I get up I unplug it, use it for a minute then put back on charge while showering. Then when I leave for work, I know its fully charged at 100%.
I guess I'll be switching out phones at Best Buy today as well. Phone keeps losing 30-40% overnight (more like 5 hours max since I'm a night owl) even with everything turned off. When I do get back to a 90% charge before I leave for work at 8am, I'm usually left with 30-40% by 5pm after 15 texts or so and a few emails.
I am fairly sure all new batteries have a chip in them that regulates the power. So you HAVE to run it down to 0-5% and charge it back too 100% several times before the battery is even calibrated for use. That has to be why its 50/50 battery sucks battery is great, just let it drain and charge it again.
battery life simply not acceptable
Hey guys,
I know many people post on battery life.
Here is my situation.
I do not care about beauty, but functionality is a must.
I am in the hospital from ca 6am to 7Pm and I have Q4 call meaning every fourth night its to midnight. That is simply a fact of my life.
My requirement:
I need my phone to last for this duration without recharge.
1.)
I don't need or use widgets
2.)
I don't need or use a wallpaper other than a solid black background.
I do need and use:
the GSM radio and wifi both need to run the entire time and reception is what it is.
My applications of use:
merck manual, dynamed, epocrates the usual in my boat.
I really really want to use this phone, but battery life wise only my blackberry with extended battery and my iphone 4 can hack it.
If any of you have any suggestions on what I could do plz let me know. My last resort is carrying two batteries, but that would frankly be admitting that this phone is inferior to the iphone 4 which can hack a 20 hour usage day in my setting.
(I absolutely cannot turn wifi or 3G off both must run)
I am open to all suggestions including the task killr controversy or anything else constructive one may have. Any extended size batteries out there for the captivate?
Thanks a bunch in advance.
(Having had my secretary spend 4 hours rooting the phone and sideloading Merck manual is a testament to the pathetic entity that is AT&T by the way. If you have professional apps from an institutional subscription you cannot download the software from the market...)
PS: My secretary is not exactly a hacker so forgive the 4 hour timeframe.
I consider myself to be a heavy user!! I like to text, browse the web, listen to music (either from my own files or streaming,) check email and comment on facebook all throughout the day. I did that perfectly fine with my Bold 9700, that battery lasted a full day or more.
I had an iPhone 4 and my battery would not last my 8 hour work shift!! I either had a bad battery or who knows what was going on with that phone. I didn't even leave the apps running...the phone was nice, but that battery killed it for me. I don't understand how some people got a full day out of it.
On the Captivate the most I have gotten has been around 10 hours of use and that's not even using it how I normally like to. I stop charging it at 8:30 and my battery is 100% around 10am I'm already in my low 90's or upper 80's. I don't have any widgets updating, I have a black wallpaper, I don't have the haptic feedback on, and I sync email hourly.
Could my battery be bad?? How can some of you manage to get 16 or so hours out of it??
My phone was off all night and charging. When the phone came off the charger this morning the light was green (100%) and powered off.
I powered the phone on when I got to work and let it discharge while sitting on my desk. I got to work at 8AM. By 12:30 the battery was at 35% and now an hour later the battery was at 8%.
I've attached screen shots below showing the battery level, time started, time with screen on, etc.
This can't be normal battery drain? In less than 6 hours my phone battery was dead. Screen was off, just sitting on my desk with the occasional use to see who was sending me text messages.
Running the deodexed and debloated ROM with Adrynalyne 4.4.2 kernel (running at 1GHz and smartass governor)
WIFI does put a drain also, shouldn't that much unless it's consistently searching or connecting and disconnecting
I believe Cell Standby means searching for service. Any areas where you have poor service at your job? Weak or no service will run the battery down quickly because the phone constantly searches and strains for a signal.
Where I work my desk is in a basement, and there's no or barely any service, and the same thing happens if I don't put it on airplane mode (but I turn WiFi on).
Same thing happened with my Droid, but it might be more noticeable on the Thunderbolt.
I took the screenshot in a conference room where signal is a little less. I sit near a window and usually have 4-5 bars. I had wifi on for about half the time it was started and turned it off when I noticed the battery at 60% in 2 hours. Still went down another 30-35% in the next 2.5 hours with wifi off, so about the same battery drain rate.
Bars don't mean a damn thing, the signal level (db) is what tells you how good of a signal you have.
this surely doesn't look right. I am on same kernel, stock battery and my phone lasted 28 hours doing almost nothing. I usually get 8 hours on normal use.
god, i am stock and can leave my phone on overnight and wake up with over 90%
30% cell standby is a lot of time searching for signal. Use the sense widget to turn on and off mobile network (if on a sense rom. If not d/l one off market or go into settings) and turn it off at work. You will still get txts and calls when you have service but it should save some significant battery life not going in and out of data service. You can of course use airplane mode if you don't mind missing calls and txts

Go to the market and download the battery calibration app. Follow instructions to a T n you'll prob be good. Charge it to 100% at about 4215Mv, then hit calibrate. Remove charger, let drain till phone turns off on its own then let charge to 100% before you unplug. Takes time, but worth it. Also a little FYI, after you calibrate it and unplug the charger, the battery level may drop a few % instantly. Just because the phone doesn't really know where the charge REALLY is till you turn the phone back on and charge again. Hope this helps. And YES you need to be rooted
4Geezy ON DopeDiculous's ROOTED TBeezy!
dopediculous's idea is good. I've never tried a calibration app, but it sounds like it would work.
Something else you could try... this works for me every time. What happens is when you flash a new kernel, your battery stats often go haywire for some reason. Here is a good fix that won't take much time to perform:
1. When your battery is at a 100% charge, reboot into ClockworkMod Recovery.
2. Scroll down to Advanced and hit your power button to select it.
3. Scroll down to Wipe Battery Stats and select it (this wipes your battery stats).
4. Repeat.
5. Scroll down to Back
6. Reboot.
EDIT: Sorry... it was late and I was very tired when I wrote this last night, but before you begin the steps above.... completely drain your battery first (phone should shut down). Then, keep your phone turned off and completely charge it until the light turns green, and then begin Step 1.

the battery calibration app does the same exact thing without the reboot to cwm
Check your setcpu settings. On some Kernels I've seen them switch to performance without me touching it, which put the phone max setting the same as the minimum setting.

I am a "minimist". I only run apps when I need them so I have pretty much nothing running in the background (except Google Voice). I don't even have a widget, only 1 screen of shortcuts. so put that into consideration before comparing your battery life to mine. I am just giving an insight about how I achieved mine.
Removed(deleted) all bloatwares (wifi calling, myaccount, lg.omadmclient)
Using Titanium Backup PRO, froze several apps (which I don't think matters, since I never see these apps running in the background anyways)
Using StartUp (the program), I disable A ****LOAD of things, so apps won't startup by itself due to whatever reason
did the HTC battery conditioning twice, then wiped battery stats
has a SetCPU screen off profile of 216/216.
no apps that sync at all (except Google Voice, which is constantly running)
default brightness
use ATK to kill tasks manually everytime I'm done using the phone, before I lock my screen (NO AUTOKILLING)
what I've come to realize is that no matter what u do, when you use the phone, the battery is going to drain. when my screen is off/idle, i lose almost no battery. For example, the day before yesterday, I lost 3% battery overnight (8 hours). Last night I lost 1% overnight (8 hours). But when I actually use the phone (screen on), i lose battery fast.
My battery life was awful the first few days but after uninstalling the capacitive buttons led notification app and calibrating my battery it got a lot better. It now lasts me the entire day with around 30% left when i plug it back in. I do turn off 4g when I'm at work and in a few of my classes because I dont get good reception.
The battery seems to last a really long time on idle but as soon as I play a game (guerilla bob thd) the battery drops about 10% in about 20mins (while im playing) and then goes back to about 5% an hour
Here's my battery life... http://forum.xda-developers.com/showpost.php?p=13438062&postcount=21
Haven't tried to stretch my battery past what I needed yet but I used it for 1 hour 2 minutes straight today and only lost 10% battery. No way thats happening on my old phone. Used to lose 1% every couple minutes the screen was on.
That's how much I'm losing.. the phone is pretty good when it's off.. when there's no network.. but I went from 65% to 45% in 1 hour, and that's just from texting, really not liking that.
Damn that sucks. I only lose 4-5% per hour of left idle. Something is prolly up with your phone.
You lose 4% - 5% when your idle? That's how much I lose when I'm idle, probably even less.
When I touch the phone, it starts to die really quickly
Dunno whats causing that. I drain pretty slow during actual usage. My screen brightness is usually 25-30 that prolly helps a lot.

Damn, same here man, what about GO SMS or Go launcher?
Does that kill battery?
I removed Go launcher, I really loved the look, but testing if that kills the battery?

I use both and have never experienced them using any more battery than any other launcher on either of my phones.
So the other night I charged my phone to 100%, the LED was green indicating it had come to a full charge. I unplugged the phone and left it on my night stand to see how it held it's charge over night. It was shocked in the morning when I woke up and found my battery had depleted drastically. It had gone from 100% to 47% over night. 53% loss while it was sitting on my night stand and I was sleeping. My old iPhone 4 would only lose about 3 or 4 % over night. This seems ridiculous.
First thing I did was jump into my battery usage screen to see what's been killing my phone over night. This was from roughly 9:30pm till 6am.
I'm running ROM Xi40 126.
It's pretty atrocious with the battery life. I'll have it fully charged, and then unplug it and within about 10 minutes I'm already down to 97%. It's loosing 1% every 5 - 8 minutes and I'm not doing anything with it. Just sitting in my pocket or on my desk.
What could be causing this? I'm going to try a different ROM and see if that helps.
Download betterbatterystats to get a view of what apps may be causing wake locks. What are your sync options? Check Facebook sync, and the actual app settings. Facebook my default refreshes a live feed and every hour, its a real drain. I'm on r123 Xi40 and my battery life has been pretty good.
I've set global sync options to once a day as opposed to hourly or something.
I don't have any widgets open except for a 1x4 clock / weather widget on my home screen.
I flashed CleanROM 4.5 RC1 Lite and it appears to be a lot better so far. Only lost 5% in 30 minutes with screen on and downloading stuff over WiFi and LTE. I'm charging it to 100% right now and will be out for the afternoon, 8'ish hours. I'll see how the battery lasts.
Changing to CleanROM 4.5 seems to have solved the issue. Been unplugged for nearly 3 hours, an hour of which was streaming music from slacker over LTE, and I've only lost 10%.
My guess is there was an application running in the background that got killed with you flashed CR 4.5. Happy you got it resolved though!
Download SmartSync Disabler
So what you wanna do is use SmartSync Disabler. So download it, enable it, reboot. Then you should be good to go. This is a bug where your WiFi and Data connection is turned off and on randomly, and intermittently throughout the night. This causes for the drain and heat issues maybe.
I took the phone of the charger at 7am this morning, it had the green LED on and said 100% so it was charged. I sat it on the window cill and never looked at it, Went out at 11am and checked the phone at 11.30 it said 4% and had a critically low warning. I said this can't be right, rebooted the phone thinking battery readings must be wrong, it restarted at 2% and then turned off.
Now what the hell could of caused this, I am using an Anker battery less than a month old. I have noticed in the past if I leave an app open such as a twitter client and lock the phone without closing the app it doesn't sleep like it should and eats battery, and this is what I did this AM, checked twitter, locked the phone took it of the charger and thought no more about it.
So the question is why when I lock the phone do apps not sleep like they should? Auto sync is off etc, and secondly when I connect this phone to a charger how exactly do I find what killed my battery the last time?
I should add although this is an exteme example without putting my phone in airplane mode half the day I will not make it through the day which is pretty dire for a phone.
Ok I have found out my stats, I challenge anyone to beat this.
3hrs 34min on battery with 2 mins screen on time and I was flat.
Android OS 72% is the battery killer. Phone is obviously not sleeping. Anyone any ideas?
If I play games on airplane mode and on lowest brightness, my battery lasts 1 hour. It's the original battery and I'm going to buy a new one soon
