Official ICS - battery life is actually pretty good, screenshot inside

I updated "cleanly" as per my previous post,

Looks good!
What is your brightness setting?

More info about your settings please?

Auto mainly but i adjust sometimes upwards, as ICS auto brightness can be a bit too dark for me sometimes.
I turn wifi, gps off when im not using it, NFC is off if that makes a difference. 3g is on always. Nothing special, I just "use it" as I normally would.
I think 2 days and 8 hours is pretty good going?

No idea feel free to ask me specific questions!

what apps have you used in this 2+ day period?? games? streaming video? web-browsing? These are the most common uses and they are also the biggest battery killers. I'm sure if I had my phone in airplane mode & barely used it at all I could get better battery life than that. Please give us more details on the specific apps, etc. you ran in this period (to the best of your memory, of course )

Hmm probably only an hours worth of "apparatus" - game, good couple of hours on google reader, facebook etc. no more than an hour on the phone.
my "normal" usage really; not trying to be overly conservative, but also not constantly on. certainly nothing to suggest that I'm getting any worse battery life than I did on 2.3.x

Next time you get this kind of usage from a full charge down to zero let us know your screen on time please.

Battery life stats don't mean much if you don't really use the phone for those 2 days. I'm at 16hours with 66percent left.

Here's mine. A day and half. Similar battery performance with GB even though that Android OS is way too high (higher than Screen)

Yes; that Android OS' looks like a statistic and therefore has a 87.8% chance of being made up on the spot (like that one!).
This is a sample of my battery life and quite unusual for me; Mobile Standby is the highest because I spent five or so hours in an area with very poor coverage, when it could get a signal it was 2G.
Wifi is on when I know I have a hotspot I can use. AutoSync off unless I need it. Bluetooth wasn't used. Screen brightness mostly at the minimum with some time at Auto. Latitude constantly running in automatic update.
Screen on time was 2 hours, 30 minutes and that included approximately 20 minutes of Google Maps (not Navigation).
The biggest difference I've made on my device is to log out of Google+. My use is mostly checking two Gmail accounts, browsing the web, using DropBox / Documents-to-Go, texting, some photography.
Disabling Latitude's AutoUpdate stops the device from waking up with the screen off (all those little blue ticks on the use bar) and makes a big difference to battery life when I'm on the move.

How can you guys take screenshot on stock?

Hold down power and vol. down simultaneously for a second or two for a screenshot.
Also, nice battery life. I've been running about a day with ~50% left, 2 hours of screen time and somewhere around 30 - 45mins gaming. WiFi on all day and calls/texting was minimal.

I am running stock 4.0.3 ICS and battery lasts only 10-11 hours.(Data Disabled, Occasional Wifi Use, Brightness reduced to minimum.).

What's your screen on time during the ten hours?

Do you guys think there's something wrong with my N7 battery?

I'm looking for other peoples battery stats. Seems like a lot of people say the battery life is "Great" but I have no idea what that means lol.
I'm getting about 5 hours of screen on time from a full charge. Here's my typical usage:
-Brightness set to the minimum
-Wifi only on while screen is on (I toggle it with the widget)
-No bluetooth or GPS enabled
-I play games like Dead Trigger, Gears & Guts and use the internet browser.
Anyone else's battery usage similar to mine? Or would you think my battery is defective?
I just upgraded from the Sony Tablet S and I'd typically get 7 hours of screen on time with the same usage.
Let me know what you think!
Thanks

i have basically the same usage habits as you. i use my n7 with 25% brightness and i can get about 10 hours of constant gaming and browsing with wifi on. it might be your device i think.

Hmm, I don't quite believe that. You must be exaggerating, or not talking about screen on time from the battery menu.
I finally found a good site that broke down lots of battery tests. Seems like my battery is totally normal. They said that for 100% 3D gaming use, the battery lasts for 4 hours. With no 3D gaming, the battery lasts for about 10 hours. My screen on time of 5 hours with 90% 3D gaming seems to fall exactly in line with that.

If you are playing games, obviously the battery life will be significantly reduced. The really great battery stats are generaly just web browsing and video, often with custom kernels. For what you say that you are doing, I would say that your numbers are about right

4.2.2 stock battery life worse?

I'm noticing that battery life is worse in 4.2.2 - I was on cm10.1 nightlies w. Cm10.1 kernel and was getting about 10 hours screen-on time before I needed to charge, but I'm getting 7 hours at best on 4.2.2 stock (rooted, bootlader locked).
I have the usual culprits turned off - Google now, location services, currents background updates etc. So I hoped I would at least get the same.
Anyone else?

Yes! I just read that. I am just about to do it now.

I can't comment on battery life, but did notice something a little alarming with regard to battery drain. Was on the couch for an hour talking to someone using viber, just plain text. No video or audio. Tablet was plugged into the wall, and after about an hour i noticed that the battery had gone from 100% to 98%. Should not be possible for a simple messaging app to cause the battery to drain faster than it can charge. screen was on auto brightness as well.

Did you look at your battery information to see what was using the most energy? Display is always far and away the highest for me, and if it was on Auto Brightness, depending on the lighting around you, it could have been running at full brightness...which would be a pretty massive drain on battery.

Once the device reaches a full charge it cuts off the power draw to avoid damaging the battery. It's normal for it to hover between 97% and 100% while still plugged in.

I barely get 6 hours of use now.

I did not look at battery usage, but the screen was generally dimmed, where as normally i have it manually set to full brightness, and nothing was running in the background that would not normally be running, that is to say nothing other than android stuff, it's basically a tablet for internet, email and skype/viber while i watch films etc on my computer

Indeed, but this has never happened before and i typically run the device with screen on maximum brightness. on 4.2.1 it would always show 100% when plugged in, i never once saw it drop to 99% or below.
So without further analysis of the issue, it could either be that something is sucking more power, which would seem odd, or that the update has brought about changes to the way the device charges, or changes to the way the device displays the battery level.

Damn guys, I don't know what I'm doing wrong, but I'm jumping around in happiness when I manage to get over 6 hours of screen time lol.

I've been on battery for the past 12+ hours with about 6 hours 15 minutes screen time and still have 36% battery left. Battery seems at least as good as on 4.2.1.

Thanks, I've done this now, and get about 5~6 hours of screen time now with around 50% left.

My battery life has gotten considerably better after updating to 4.2.2. The biggest improvement is how little the battery life drains on standby...it's nearly nonexistent.
Sent from my Nexus 10 using Tapatalk HD

Standby has always been great for me. With stock rooted 4.2.2 I'm getting great battery life. Loses maybe 2% after 8-10 hours idle. In constant use I'm averaging 11 hours on screen. I have everything on and synced but as I'm indoors I stick to 30% brightness. Also, I'm mostly just browsing. With games the life would be less for sure. Totally satisfied with the battery life of this tablet. If yours is getting truly bad battery life I suggest you try searching for rogue apps. After that, try a complete reflash of the stock image which deletes everything. Another thing I've found that helps performance is setting the WiFi band manually. As I have a pretty good router that utilizes both the 5 and 2.4ghz bands I set mine to 5ghz only. I live in a town house and 2.4ghz can be pretty congested even after turning my antenna power up to 150mv or greater. The 5ghz band is pretty open. I'm getting load times on webpages comparable to my i5 2500k sandy at 4.5ghz and ssd with its 5ghz WiFi n wireless card. This is the quickest rendering tablet I've ever used.
As an aside, the complete re image to stock 4.2.2 from Google might fix reboot problems as well. It seems to do wonders for people with battery and other issues on early n4s. My screen on mine is new but the hardware is from launch day.

My battery life is significantly worse after the update. I flashed back to stock 4.2.2. It seems that the problem with mine is my tablet isn't sleeping. Android os is the highest battery user. Maps is taking a lot too. I have Google now and location services turned on so I'll try disabling those again... No rebooting though

Nexus 10 battery life

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.

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.

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.

Sent from my Nexus 4 using xda premium

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.

Battery Life Worry/Question

My battery life has been pretty good. However, the number one thing consistently using battery is "Android System". Is this normal? Thanks!

Same here. On all my other Android phones Screen is the top user.

U are using ips technology on the screen unlike amold that saamy used which kills the battery in hours in full brightness . As you could see that the iPhone has good batttery life because the 720p ips screen.

I've found that rebooting the phone after taking it off of charge, the battery life is awesome. There seem to be some wakelocks that kill the battery and for some reason, charging has something to do with it.

I don't know if this is why, but I heard the G2 has special screen technology that greatly reduces battery drain.

Those claiming that Android System > Screen for battery use on the G2...I'm coming from a Nexus 4 which is also IPS.

Yeah, somthing about 30% lower battery use or something like that. It's 6 hours since I took mine off the charger, must admit very moderate use, some toying, some photos, some mails and 1 phone call. but still, my phone is at 96% battery. My old S2 would be at 60% at this point.

Over 48 hours of use, more than 50% battery left. 3,5 hours screen time. Android system worst offender with 35%, screen 2nd with 25%.

If you look at the programs listed under Android System, try uninstalling the ones that you would never use. This has seemed to help me. But to be honest it was kind of unnessary because the battery life is just crazy badass. In a few weeks or so when the devs have there way this phone is going to be epic.

It is two things, which by the way are great news.
A) LG's screen tech which doesn't refresh pixels when the images are static
and B) IPS
What we can't control is screen power consumption, but guess what? We can control android system consumption through kernels and roms. This means that we can *hopefully* expect EVEN BETTER! battery life since the screen is, for 80% of users, the main culprit for energy drain.

Just a quick note that flashing CleanROM on my ATT LG G2 basically took my battery life from <20% at the end of the workday to just under 80% at the end of the work day with increased use on the CleanROM install. Highly recommended.

Been off the charger since 6:50 this morning. Sitting here at work doing some texting, Words With Friends, and a test call for a co-worker...96% at 12:15pm. My Nexus would have been at 40% by now.

So is Android System different from Android OS?
I normally can squeeze out 15-22 hours since installing Snapdragon Battery Guru. Which has been working great until today.
Here's my situation today:
-100% charge at around 1230am. Light to moderate usage leaves me with
-77% between night before and waking up (only dropped like 2% overnight) at
-830, then i worked from 9 to 1230 so i didnt use my phone too much. But since ive been off work ive been using it more so im not too surprised about my low battery level currently.
But what concerns me is Android OS using half my battery! It says its been active for more than 4 hours and i dont understand where it comes from. Its way more than my screen usage even with a screen time of little over 3 hours.
Anyone know whats up with Android OS? It doesnt tell me what is running when i select it so im lost.
Also ive done many of the suggestions in this thread with positive results. Ive been monitoring my wakelocks and since doing some of the suggestions on here nlpcollector has actually gone down.

Just to benchmark .... I used the phone moderatley ..
I did.. a little over 50 hours of total on time
4.75 hours of on screen time,
2 hours of spotify with bluetooth for the entire time,
2 hours of MapMyRun with GPS running ..
then various text messaging and a couple phone calls
The only modifications i've made to the stop experiance is taking of google's location service for programs, but leaving GPS active .. and changing the screen to auto-brightness, baseline of 50%.
I came from the SGS2 ..... with 1 hour of on screen time and the other spotify and bluetooth .. i'd be around 10-20% after 8-10 hours !!!!!

Mines pretty awesome.

I'm not sure if my battery is defective or not. Right out of the box was around 75% and I drained it until it turned off then charged it to full.
Over the next few days at work it's on wifi and then on 3G/4G before /after work. I pull it from the charger at 7:30am and by 7pm its at 40%. Then on Friday night I unplugged it at 12am with 100% and woke up the next day with 80%. It's dropping like 1% about 10-15minutes. Would a factory reset fix the battery drain? or call for a replacement?
