Another battery life thread...

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??

Faulty Hardware Battery drain?

Hey everyone,
I recently upgraded to android ICS 4.0.4 from 4.0.3 with the hope of the battery issue no longer an issue with my nexus s...
Though my battery drains around 1% every 2-4minutes with normal use, as in just scrolling and going through settings (not using apps), very very light use. I have factory wiped it , I have installed new roms and kernels - mixed and matched, uninstalled apps and installed apps one at a time (to see what drains), I even disabled some the high % wasting applications...
My screen dim is on the lowest, wifi is off, data is off, sync is off, gps is off, screen rotation is off, yet still no improvement, I even fully discharged my battery and re-charged it (while phone is off)- no improvement. And i also changed the CPU settings to 800max and still no improvement.
and when i'm playing a game or something it drops around 10% in ten - fifteen minutes, sometimes drops more.
When my screen is sleeping it takes around 1-2% every 1 hour-2hours, which I think is normal.
My screen is usually 45-50% Battery used by the display and backlight
Android system is usually 15%-20%
Android OS is usually 3%-10%
My battery is only about 4-5 months old, and I've always charge it when its 5-10% left, I don't let it die. I'm going to purchase a new battery to see if the problem occurs, if it does, can it be something with the phone hardware?
But any suggestion on what it is?
I've looked around on forums etc and none of the solutions have worked.

The display is going to use the most. There is no way around it. What are your average use times? If you're only losing a few % an hour idling, that's great! The only things I can think that would help is using black backgrounds whenever possible. You also have to keep in mind you're gaming with your phone and that's CPU intensive, which will cause more drain.

Yeah the display will use the most, but I remember it used to be around 30-35%, I've just been seeing how the battery is lately - just going through settings etc and it goes down every 2-3 minutes by 1%, it used to last much longer than that - 1% every ten mins. Sad thing is - I do use a black background lol to save battery and with games I hardly play them but when I do bye bye battery.
try battery callibration apk from market before you recharge your phone and no use 3g just 2g and make conservative 100/1000 the governor.

I'll try the battery calibration and see how that goes, and change the governor as well to see if any improvement.

Yesterday morning i charged it full 100%. I took it off the charger and left it on the table. It had no wifi or games running at all( at about 8 am) I leave it there all day until about 6 or so. and when i come back its down to 30% WTF IS THAT!. On my dads phone he could have 1% battery and leave it standing by all day and night and he can still turn it on without losing the last percent. Its not an iphone either. Hopefully 4.1 Jelly Bean will have some battery fix for the nexus

BetterBatteryStats. Your best friend when it comes to battery life.

Yeah. Mine isn't bad, but I also just go by my screen usage. If can't get at least 3 hours by the end of the day(which is probably 13 hours), then something is up. Note on calibration, it won't do anything. Those stats are reset once the phone is charged past 90% IIRC. On top of that, our batteries have a different way of reporting the charge. It's not the same as htcs.
Sent by pocket technology

I managed to get my screen down to 40ish% and my Android system is under 10% and I've been timing my battery and noticed every 4minutes exactly it still goes down. I tried calibration does nothing as you said. I'm gonna download betterbatterystats and I have cpu spy running atm...

xda will do it!

I have the same issues. 10 hours max not touching the phone at all. Stock, custom, matrix, nothing helps.
Maybe 6 hours if I start using it moderately
Sent from my Nexus S using xda premium

Similar issue here. Tried all combinations of ROMs (jb,ics,gb) and kernels (air,marmite,matr1x,lucid) to no avail. Even reverted back to stock GB ROM, radio, and bootloader. Nowhere near 6 hours talk time or 200 hours standby time. I get between 8-10 hours standby time if I'm lucky. I even tried turning the phone off overnight, with a full charge even, and when I went to turn it back on in the morning the battery was dead and I had to plug it in to turn it on.
I picked up a new battery today but the issue seems to persist. I put the new battery in at noon with 98% charge and now 2.5 hours later I'm down to 70%. I am convinced there is a hardware problem that is causing the battery to drain excessively. GSAM Battery Monitor and stock battery stats all look normal with screen using the most battery followed by Android System etc etc. Aside from the battery problem, the phone is awesome and I really don't want to have to buy a GNex when this phone is still salvageable.
So what part of this phone could drain the battery so fast with the screen off? It could be the CPU, GPU, screen digitizer perhaps?

I know you tried with your old battery, but could you try again with the new battery with your phone turned completely off? If there's a drain, then there's definitely a hardware issue.

Phone off for half hour yielded a 9% drop in battery life. I'll keep the responses in this thread only. I just realized every time I respond to a thread it gets bumped to the top of the forum!

Definitely something wrong. I don't lose anything with phone off, so something is messing up hardware wise. Did the phone get water damage?

[Q] Worried about battery, new tablet

I have only used my Galaxy Note tablet a few days, and I am probably using it approximately 5-6 hours tops. It is needing recharged every day! It takes hours to charge and then I only get 5-6 hours usage? Is this normal?
I would appreciate any response.
Thanks.
Galaxy Note 10.1

Try going into setting and then battery see which application is draining the battery and get rid of it.
Note has one of the best batteries around but if you use non stop for heavy application like gamming you should get between 8 - 10 hours of actual usage.
If not then may be there is an issue with your charger or battery get it checked and replaced
Also Note takes a long time to charge around 5 - 6 hours

Hmm.. I use it and get about 8 hours +/- depending what I do with it. I normally use it to take notes for about 5 hours (around 3 hours of actual note taking, 2 hours of doing scratch work for homework on it), and I'm browsing Reddit for the rest of the time. I've noticed that I've had to charge it more often lately, but I've been using it to watch Netflix mostly in the last couple of days.
In my experience with the Asus Transformer, I had to charge almost everyday as well because of my high usage. What do you normally use it for?

A day's heavy usage is normal.
Charge from 0-100% takes about 5 hrs for everyone.
In simple terms, the Note 10.1 has a large capacity
battery that takes a while to charge. Rechargeable
batteries lose their ability to hold charge over time,
but that time is measured in months and years.

I am not sure, maybe I am reading this battery meter wrong. When I go to settings and open battery, it says "51% discharging" and then below that says "15h 12m 59s on battery."
We are mostly using the tab for web surfing, and watched a few Youtube videos. I don't believe anyone has even watched a full show on it yet. It has only been in use since Thursday night. I am not sure what to think.
Doesn't the 51% represent how much battery life is remaining? And what does the other stat (15h 12m 59s on battery) represent?
I appreciate any help or advice.
Also, The only items it shows below that is Screen & Device Idle. Screen says 99% and Device Idle says 2%.

99% usage for screen is quite odd. Maybe try turning brightness down or trying the power saving option for screen. Also, and this may sound silly, but if you haven't rebooted it, that is worth a shot, sometimesthings just drain until rebooted.

To answer your questions
51% is the amount of remaining battery.
15h 12m 59sec is just what it sounds like. It's the time the tablet had been off the charger.
Most of the time your screen should be the highest. Here is what mine looks like. It's been a light day.

Please help me figure out if this kind of usage seems appropriate for battery drain. I am keeping a little log to see how fast it is draining. I just cannot understand if this is normal. Here is a small sample for this evening to see if it seems normal. I only been surfing some, no watching anything.
1109p at 99% battery
1130p at 94% battery
1155p at 90% battery
under settings, battery, all that says is screen 100% no other items listed below
Is it normal to get 5 or 6 hrs then have to recharge even if you are just surfing? I thought people went for days without charging this. I have never owned a tablet before, but I never have to charge my computer or phone this much and I use both for more time than this and not had to recharge this soon.
I am just trying to understand if I have something se tup wrong, or have a faulty tablet.
I truly appreciate all the help from everyone. Thanks.

Have you tried changing the brightness to about 30% (about the same as what I have it on and I get about 3-4 days charge with light usage)? Also rebooting, uninstalling recent apps, enabling/disabling power-saving options?
If nothing else works, try a factory reset and just use it like normal with no extra downloaded apps from google play. Try that for one charge and if it's still bad, there must be something wrong with your unit.
Would you be able to take a screenshot of your battery status window? (hold spen button and hold spen on screen for 2 seconds to take screenshot). It could help us determine the problem. If you could get screenshots of both the main window listing the things that have used battery, as well as the window after you tap the battery graph, that would be great.

Mate, I don't honestly believe you have a problem... I use my tab for around 10hrs/day and I need to recharge it... I do use it for mostly video files...
I also have the 3g version. What's yours? If it's 3g and you are in an area where you don't have a good signal then the modem will be looking and consuming battery power...
Even though this tablet has a large battery, it is usually used up within a day or 2... Try leaving your laptop on all day, it won't last too long either...
That's the main difference between a laptop and a tablet (even if the laptop is in hibernation it will still kill the battery eventually).

Accurate battery life?

Just got a new Z3 D6616. This is the battery life projection I'm getting. I bought this phone because I heard great things about it's battery life. Also, when I saw a YouTube review, the guy's phone had a battery life projection of several days. Is something faulty with this specific handset? Am I doing something terribly wrong? Please advise.
PS. I'm at about 30-40% screen brightness with the adaptive setting on.

You should actually use the phone from 100% doing your daily stuff till about 1% and take screen of your on screen time. On screen time is what matter. They claimed to have at least 8 hours SoT with normal usage but the max I can get is only 4.5 or 5 hours.

I did a lot of reading before buying the phone. Heard about the "memory" screen or something that helps towards battery life. Several users claimed 10 hours SOT. Could it be the newer firmware that might have reduced it? I'll post the YouTube videos I saw shortly.

I use brightness at about 1/3 and have location and autosync on. I get about 8-9 Hrs SOT in a 36Hrs period.
At first even I got 4-6 Hrs SOT until it calibrated over a few charge/discharge cycles.
It takes a few cycles for the battery to calibrate, if you want to do that faster do the following:
1. Drain to 0-1% with normal use
2. Do a full charge till 100%
3. Do another full discharge (Dont charge in between)
4. Do another full charge till 100%
5. Now just use it how you want.

Thanks! Guess I'll have to report back report back after a couple cycles.

I have the same problem, I have enable the stamina mode, have the brightness at half and auto,and the battery won't last for one day,as an example today when I get up after I unplug the device it go from 100% to 99% right away and now after 10 hours without game,photos just Internet reading over WiFi the battery is at 31%. It doesn't seem normal, what should I do?must go to service?

I'm at 59% and my phone predicts 1 day remaining.
D6616 as well
I do suspect an app draining my battery though...

I can get 6+ hours if I limit my brightness, but I settle for less with max brightness throughout the day.

The battery life I'm experiencing is worse than the "forecast", which is essentially what worries me. Regardless, I've no right to whine unless I've cycled the battery completely at least once since it is after all a brand spanking new phone.

I doubt I'd get the 24 hours from now with my current use either. As long as it lasts me throughout the day I'm fine.
I can generally go the entire weekend without charging my phone though.

Ive gone through 3 Z4s (Cosmetic defects/lightbleed) on my 4th Z4, all of the were bad until they were calibrated within a few days.

I think you mean Z3s...

Lol yes.

I fully discharged and recharged my phone. Now I got 18 hours usage, including 7 hours SOT with the screen on max brightness for half an hour. It's getting much better now, certainly a huge improvement over my previous phone!

That's more like it, it should get a little better.

Please have a look towards the end... My phone's been awake when I was asleep. Is there an issue with this phone deep sleeping? While I get a good SOT, the idle drain is too high! Please advise on how I could investigate if a particular app is doing this. I used to use "wakelock detector" but that no longer works without root.
EDIT: Stamina Mode always on.

I have the same problem too... Whenever I leave the phone idle, even with the stamina mode on, it still uses the battery as if I was using it.

Last 5% battery

My battery is work perfectly i can reach 5_6 hour screen on time
But i have a problem with last 5 % it's drain too fast
From 5 to 1 within 3 minute but when i connect the charge it's
Immediately up to reach 7% and back to its normal
Anyone know what cause the problem?

Samething to must of users of s6.. i think the battery has some problem and didn't calibrate well..
I tried to calibrate with some methods but always same drain... so do't know..
But if your battery reaches 5 or 6 hours of sot is incredible.

Exactly same for me and I've tried 'recalibrating' the battery at least 10 times with all methods available!
For me, sometimes this rapid drain starts from 10-15%. I usually reboot the phone and it goes to the correct number and discharges less rapidly, but still quicker than usual. I experience the same thing on my tablet.
I guess it's the outdated Li+ battery technology

So the problem not from my charger or cable
Before i face this problems with my old s2 plus
And i never see that with my s6 untile last 2 week
