After so many threads about battery issues I decided to take a plunge and try battery drain. Problem is that I have extended battery and I went from 100 to 1 percent in probably 5 hours but I'm currently at 1% and running with screen "always on" and playing YouTube vidoes in HD and yet it's not going anywhere from 1%. It's been like that for 2 hours now with screen on and youttube playing. Any better ways to drain it?
try tether on too and have a computer use it as wifi router
When I turn the display brightness to 100% it drains my battery crazy fast.

Fastest way is to simply play some of the more hardware intensive games. I find that about 2-3 hours of PSX does the trick.
pandora lol
I'd just watch lots of...uhhh...nevermind.
Turn on gps, wifi, bluetooth, stream music at 100% brightness. Make sure the speaker is being used.

maybe the phone the phone isn't really reading properly your non stock extended battery? Might not be a rom issue?

Start tethering, turn brightness up, start watching HD porn... viola! Battery will be dead in no time.

I have 2 extended batteries from different vendors and both of them showing this issue.
Angry Birds?
Or turn on GPS and driving navigation - mine will drain the battery faster than it can charge with gps/navigation running.
Netflix with with background tasks. Max brightness. All of that fun stuff.

I downloaded a program to drain my gf's xperiax8.. It was almost fully charged(99%).
Try battery discharging on market.
It says a couble of staff, but only vibration is working. And makes difference.
I opened music gps wifi also.
It drained in 3-4 hours ang regular drain is 3 days with light use, and customizations..
Edit: also with setcpu I set the MIN frequency same as max(and max is OC'ed)
Sent from my MB860 using XDA App
battery refresh in the market seems to work pretty good..
So... with 20% brightness, no auto sync's, Just web surfing, light youtube and maybe 12 minutes of music through headphones. I can only get about 5 hours of screen time at max. What? At this low brightness/no games setting, I expect at least 8 hours. Or am I over shooting it?
Any ideas? What is going on? :[
I'm on the lowest setting for screen brightness and I am getting a little over 5 hours with 5% battery left.

I've read those, but I didn't really see an answer? I need to figure this out, because I have already unlocked away my warranty.
I use auto brightness with trinity kernel at 1.4 . I'm getting close to 10 hours with browsing, 2 movies and Pandora all day.

Do you recommend a non-stock kernel?
Can we start collecting some stats. Can people post what battery percentage they lose every 30 minutes or an hour of just browing websites on wifi and/or 3G and specify which one, and also average screen brightness during this time. I know this tablet using superAmoled will have less battery life than if you watched movies, but there should be some standard of web browsing.
I use about 20% battery life, just on wifi, brighness at max of 30%, battery stats showing no abnormal activity in the background.
[edit] on ICS 2nd stage. using Chrome browser.
About 13% per hour here. This is a P6800, using wifi only (radio turned off), in an area with low wifi signal (2 bars). Minimum brightness, CM10, default JellyBean browser.
(EDIT: 20% in 1.5h, so 13-14% per hour)

i did read that yesterday while scouring the web for web-browsing results for the SGT 7.7, which is why I was hoping we could all share our experiences, since I know myself, and it sounds like others, are not getting 7 hours of straight web browsing. Me I am getting 5. Starting to think it is a hardware defect and to contact Samsung, but wanting some more data also.
That's a bit worse than what I'm getting on CM10. Quite impressive, I'd think Samsung would tune their ROM better than what the community could do in a couple of months.

Screen shot you battery usage and post. Maybe there is an app we can see causing your drain. If your screen isn't drawing 70%+ there may be an app running out of hand.

With wifi and auto brightness, max is 5 hours screen up time. How they get 7 hours? @@
well I switch from chrome to opera and battery life is much better in initial usage. 16 percent battery in an hour in 15 minutes. auto brightness in a dim indoor setting. tablet temp is also not going over 100 where with chrome that was normal. Will test for a few days.
end of one full battery session only using opera mobile to browse.
with 37% left I had the screen on for 4.25 hours, auto brightness indoors, most of which was browsing. while browsing i also downloaded 2 HD movies from google play on wifi as well as updated about 10 apps and downloaded a couple more. after watching 1:35 minutes of an HD movie at about 80% brightness, the battery only went down to 26% from the 37% which is what i am used to for this tablet for video, it's amazing due to the lack of pure whites and a lot of dark colors including the black bars. browsed the web another 20 minutes, only lost a few more percent. put it on the charger at 22% and will pick it up again tomorrow.
also regardless of what browser i use, my tablet is a standby machine. with the screen off i may lose a percent every few hours.
during the screen on time my temp went over 100 degrees only while downloading movies and browsing. and it only went to 102. just browsing with chrome the tablet would get to 107.
will test again tomorrow and see if the trend continues or if this was an anomaly. if i get three days in a row with this kind of battery life, i am uninstalling chrome and sticking with opera for now.
This is my stats after almost 5 hours on 3g. Activities includes Web browsing, music streaming etc.

using stock honeycomb 3.2, I also have the ics update but I won't do it
1 hour for 10% how much I will get? do the math ^_^
and now after 4 hours of continuous usage, still 60%

well it's been some days since i stopped using chrome and tested out numerous other browsers. here are my results.
using chrome my tab would get quite warm and lose close to 20% an hour browsing on 20-50% brightness. the stock browser wasn't much better.
i have tried opera, maxthon, boat and xscope. maxthon is just not good layout wise on a tablet. maxthon tablet is quite nice with an awesome and fast night mode that turns text into white, the background into medium gray and still shows all the pictures in full color - which is amazing for a samoled screen not having to produce all these white backgrounds. however it FC's a lot and you can see that in the comments. keep an eye on this browser as it is being developed.
xscope just doesn't have a nice enough interface for me on a tablet. boat also got my tablet warm.
so opera mobile. my battery life has gone up extensively since i started using this. with heavy heavy browsing i am getting between 7-8 hours battery life. with steady browsing mixed in with other things like using pulse, taptu, play store i am getting 8 hours+.
i monitor my temps and they stay much much cooler, like 7-10 degrees and often more. with chrome or stock i would notice the left side of the tablet getting warm quickly.
i am running the stock ICS stage 2 ROM, rooted. standby time is amazing, i will not lose more than a percent of battery every few hours. i used to keep GPS on and do quite well standby but in better battery stats i noticed MAPS having wakelock time for many minutes while on standby even with settings set so it shouldnt. so i just turn GPS off until i need it. other than that, nothing special.
for those with lower battery life on wifi browsing, try opera for a few days. let us know what your results are.
well it's been a week since I switched browsers. i have to say it's like having a brand new 7.7
chrome is uninstalled. the stock internet is never used. i ended up testing the maxthon tab browser and opera. the last 4 days just exclusively opera mobile.
i don't think the maxthon tab browser is ready for prime time even with an update in the last week. keeping an eye on it.
opera mobile has been the best option, though it has some features i feel need tweaking and others that are better, it is still a nice browser. it also creates far lower temps, lower cpu usage and far better battery life with my tab. 2 hours more per charge at least than chrome or stock.
i hope this helps some people out who are having battery issues in regards to standard internet browsing. if you encounter simliar success, please post.
I don't lose a single percentage in battery when I sleep at night after the ICS update. That's 6-8hrs of sleep. Is that normal? I am happy about it though, but is it normal?

Nice. I thought my Tab was kind of 'over-sleeping'. Haha. Thanks!
Here's my battery usage... Currently at 9% after a full days use with about 2hrs+ surfing on 3g, 2hrs of satnav and a few texts and calls. Pretty impressive i think. I am using Dolphin browser which for me blows all the rest away. Good on battery, great gestures and fast.
Here's mine. I was listening music for about two hours while browsing

Hey,
The high percentage started before I even add a mp3 file.
This is frustrating as hell.
I listen to music about 2 hrs a day.

Cant read your Screenshot
Screen - 30 %
Mediaserver - 15%
Android System- 9%
Google Play - 8 %
Android OS- 5 %
Unactive Phone - 4%
Sorry for the lack of translation...
Mediaserver is used for many things, including apps syncing, location report, anything that use a file on storage (not only mp3 but any type of file, really, playing games will increase media server usage for example).
What I see from you screen shot is that you listen to music using Google Music and it uses the media server service.

I tried using another player but Mediaserver keeps working hard. Any advice on how to contain it?
Sent from my Nexus 4 using xda app-developers app
It would be the same because mediaserver is used when files are used, whether local or cloud, whether uplink or downlink.
If you're willing to unlock bootloader and root, you can flash a custom kernel such as franco.kernel, the tweaks will reduce medua server usage and increase battery life sunstantially. But.... if you listen to music or play games all day, dont expect any change.
Sent from my Nexus 4 in a Faraday cage
right now I get roughly 3hrs of screen time while listening to music for 2 hours a day, a few minutes of gaming and a lot of 3g (reading aricles / news ).
I use Juicedefender on custom settings (15m).
how much will franco kernel asist my situation?

You might get another hour, depends on signal quality. 2 hours of music explains the media server usage. If you find a ROM/kernel that reduces the media server, the Play Music % will shoot up, because it is what actually uses the battery.
Hey everyone. I ordered my Nexus 10 in late March and just had a question: How much actual battery life do you get out of your N10? I found that I was barely able to get a day out of mine and am awaiting a RMA replacement. I did a Netflix test, where I charged it to 100%, unplugged and played Futurama on Netflix. I got about 5 hours 12 minutes before the device shut off. I have my screen brightness at 50% and no apps that would cause heavy background usage.
That is pretty good battery life for 50% screen brightness. I still cant comprehend why people need their brightness at 50% or even higher though.

Some people like me use their tablet in brightly lit rooms and outside which means in order to see the screen you need to have the brightness cranked. I never use my tablet in dim rooms.
7 hours man. That is too much

What do you have your brightness set to?
I'm on on the 2nd charge cycle, but I got almost 5hrs screen time on last charge with about 30% battery left before putting it on the charger. Pretty good in my opinion.

What were you doing on your tablet in that time? Streaming movies? Streaming music? Watching local or Streamed movies?

Mostly web surfing, youtube, gmail, G+ and facebook. Not too intensive, I suppose.
I have all sync on except for facebook and display on auto brightness. I also have a strong wifi signal most of the time.
When my tablet is AT HOME WITH ME instead of off cavorting around Samsung repair centers, its day starts about 6:45am. With all my apps and syncing, it lasts me through a work day and then some, going as late as 11:00pm and still being at 30% battery or more, depending on how much gaming I did.

When I am inside it is at minimum (which is still too bright), outside is between 25-35%
For the people who have really low battery, I have a good hunch that the problem is how much wifi sucks up. When I have wifi on I can feel the tablet is much hotter than normal, which means it is dissipating a lot of power. I suspect that the wifi traffic is the 2nd biggest battery drain for people who are browsing all day, the 1st most being the screen itself.

It seems there is a common trend with people who have long battery lives - low brightness. My eyesight is pretty bad so I really can't stand setting it any lower than 40%.
I get about 7 hours before it needs a charge and that's mostly browsing with wifi, which sounds around right according to claimed stats by Google. I'm on around 20% brightness, doesn't need to be higher.
About 8 hours, which is a full workday for me, mostly Evernote/webbrowsing/mails - no gaming. I usuall have ~20% left, so there's 1-2 hours more for emergencies.
I just ran both my original and RMA units side by side, factory reset and unrooted on Youtube playing a 10 hour loop video with brightness set to 100% and at 5h 6 minutes my original N10 hit the 15% warning, the RMA a few minutes later....so I feel kind of bad for wasting Googles time.
I think kernel and ROM have something to do with battery as well as WiFi. I have great signal and use 5ghz and I get great battery life with little drain. Before ras came to the n10 I was using cm and got amazing battery on the kernel it came with but horrible life on paranoid (early build). Also the first trinity kernels had poor battery life for me.
