Anderson Did an experiment to see how far the battery life can last on normal usage.The battery power was monitored using the app "Battery Monitory Widget"
And he came to the conclusion that The battery life could well last more than 2 days if you use just the communication tools (whatsapp, Facebook, sms) on a 2G network. With heavy data usage, the battery power got zapped out rather quickly.
You can have a look at the full experiment

I'm kind of experimenting in this too..
Today i unplugged my phone this morning (6am) and its dropped to 97% now @ (3pm).
So thats only 3% in 9 hours..
I use Facebook widget which updates + Twitter widget same setting (both auto update every hour)
I sent about 10 text messages (also received about that amount) and made 1 phone call (about 3 minutes)
All this on 3G network, i dont save on 2G/3G setting
2G coverage is very suboptimal in Switzerland, especially if you are using a Sunrise.ch contract. Their 2G performance with Edge is about 100kbit/s for download. This is a joke. I am not able to use a phone with 2G and enjoy it. Therefore whenever possible I have to switch on 3G (which is of course also not great, but at least it is much faster).
Therefore, 2G is not an option at all for me.
I am running stock on mine and I seem to at least have found some form of "battery" drain. Trying to reproduce the usage.
But I charged my phone fully, and then restarted it and "at the moment" it is holding its power sorta alright. But when I use it normally it lasts like 7-8 hours before needing a recharge, even if its just laying on my desk and not being touched.
Ok testings done. These figures are after a reboot and where I have more or less left the phone laying on my table only having a short call, and otherwise reading a few emails and responding to a few texts. The entire time autosync was on, as well as 3G Data.
1H30M -08%
5H30M -30%
8H20M -50%
11H00M -68%
12H15M -74%
13H08M -79%
14H15M -85%
15H20M -93%
At which point I stopped the test and then put my phone in the charger. Tomorrow once it is done charging I will start up all the stuff I normally run on it, charge it to full and see how well it does there when I am not using the phone at all. Quite frankly I expect a large difference simply because that is what I have seen, but starting program and then exiting said programs and leaving the phone on standby "should" not impact consumption in my view at least.
I think there is something bad with my battery, because Battery Monitor Widget says that my battery is a 1200 not 1500, without doing nothing at all it lose 1% per hour and suddenly in 10mins drops like 6%, so in 8hs aprox from 86% goes to 68% (the phone doing nothing)
I have 3G always active, whatsapp and gmail, just that. Will try to do the test again with 2G, but what I don´t understand is why it says 1200 instead 1500.
Should I get a new battery? could be deffective this one?

CM7 is the best for me
CM7 seems to be really good for me, i used 28% of it with medium-heavy use (no games, but wifi always on and a lot of playing about with) in 5 hours and at night i lost 3% in 7 hours sleep with 3G on. Not fully stable but seems better than sacrificing the smartness of my smartphone.
Lost 0% 2 days ago when sleeping for 9-10 hours i think
Today i lost 1% when sleeping for 9-10 hours
I am using 2g since i don't have 3g connection in my house.
It's a bit unstable but battery improvement is more important for me then some little bugs

Is the O4X's battery life as bad as gsmarena is saying? Just a little over 4 hours of video playback and 4 hours of web browsing?
If you read the comments of the blog article on it, you will see that there is a lot of discussion over the brightness.
By comparison to the SGS3 and One X, the Optiums has a much brighter screen which will mean a lower battery life. Of course if they set all the phones to the same actual brightness (not percentage) the numbers would be different.
I am currently waiting delivery of my 4X, but after I have conditioned the battery (let the handset configure itself to the battery), I'll definitely be seeing what its capable of.
Alright thanks, I hope you'll be able to get back to this thread when you find out more.
I've had mine since friday and I think I've charged it about 3 or 4 times now and the battery life is getting better. It lasted only about 2 hours when I first charged it and started it for the first time. But I was using it constantly.
Today I started it in the morning (fully charged) before going to work and now, 10 pm, it's been on for about 16 hours and I have 40% left. Data have been on all day and I've been signed in to Google Talk all day, I've browsed the web for a total of aprox. 1 hour, used the camera, tested the GPS and been chatting with a friend on talk. So I'm pretty satisfied so far.
It's better than my O2X.

That's good to hear. How many hours was the screen on?
I'm not sure unfortunately. But i would say between 2-4 hours.
Edit: okay it was a little less than I thought. The. Battery usage in settings says the screen have been on for two and a half hours. And that's including the time I have used after 40%. I'm down to 25% now.
My Battery lasts after a few cycles all over two Days with medium Usage (No gaming - WA, FB, eMail)........
i ca go for 1 day, with a bit gaming and usual use.
I have slightly longer battery life on my 4X HD than on my Nexus S when using the phones in the same way (casual use). But I think there is room for improvment on the battery life with more optimized software either from LG or when we start seeing custom roms for this device.
I charged mine to 100% and just dropped 8% in 25 minutes, 20 minutes of that was driving and not using the phone, no Bluetooth or anything like that. The battery life is shocking and can't wait for extended ones to become available. Besides that I truly love this phone

How many complete charge cycles have you done?
Sent from my LG-P880 using xda app-developers app
When I got my p880 I did 3 battery cycles, and I could only get about 8 hours of standby alone, no other use at all. I then did a factory reset and formatting of the memory card, which I hadn't done when I switched from my old SE X8. Now my p880 can easily go more than a day with some gaming, calls, browsing etc. My guess is that old android files on the memory card was the reason for the bad battery life. No expert though, maybe someone else has a better idea.
Today I tried the Chrome browser, and it really drained the battery. Something like 20% after browsing for 15 mins. Anybody else have experience with this?
Overall I'm really happy with this phone, great screen, fluid operation, good battery.
I've had battery drainage issues with the chrome browser as well. Even in stand-by the browser would drain the battery. It has only happened like two times for me in the four weeks i've had the phone, so not a biggy but still something you should be aware of, if you experience battery drainage issues

Mine is better
With moderate use* I went from 18 to 22 hours. I am happy...
* My N7 is not my daily driver, my pc still is... So it sits idle more often than not...
I'm totaly happy with the battery... getting at least a day and a half with normal use.
after updating its definitely drainng fast.
No drain here. I get 10-12 hours a day with heavy use and easily a day with moderate usage. Was roughly the same before update as well.

First of all hello everyone
Yeah I've literally only had my Nexus 7 a matter of a week but I can tell the difference between the battery per and post update. It seems go drain a lot quicker!
Any tips on how to save battery and keep it for as long as possible bar the obvious app killer etc...

If anything, mine has got slightly better. Used to have less than 18% by 8pm, now its more like 25%. I use it pretty much all day for YouTube, Engadget, Flipboard, Tapatalk, Chrome, music and a couple of hours of games.

4326mAh battery, 2A charger, 2.1 hours theoretically. Realistically, 2.5-3.0 if pretty much empty.
If you're using a non standard cable or charger, who knows what the charger is actually outputting. If you're charging from your computer USB Port, that's 500mAh, so 8.6+ hours. Some random phone charger, probably 1000mAh, 4.3+ hours, etc.
The brightness of the display adds to some of the drain I notice, when possible I keep mine somewhat on the dimside, obviously if I'm in an area of bright light and it hard to see then I'll crank up the brightness.
Can't complain about battery usage.. It's amazingly energy efficient even on a stock kernel considering the horsepower this thing has.. I average 20hrs or so with moderate to heavy usage.

I am very satisfied with battery life. 2 and a half days with 4,5 hours of screen on. IMHO not bad at all.

I think battery life is pretty good
I've had really bad drains since 4.1.2. I think I've narrowed it down to an issue with Google Play. I've noticed it several times - Very good battery life, but then it will go down fast, even when sitting unused. If I check battery usage, Google Play is always number one with >50% of the use.
If I force close GP, all will be well for about a day, but eventually it happens again.
I also felt it, but only by that much...not too obvious. From full charge, after only night idle, drop 3 percent compare to last time 1 or 2 percent

battery life
Hallo!
Same problem, battery drain is faster, with normal use 12 hours (before 17) and when charging phone it's just 99%. With factory reset same resoult. Now I try without all gps conections.
Anyone have good solution?
I have an iPad 3 and a rooted Nook with CyanogenMod on it. Both go days and days on standby, meaning fully on but the screen just off. My N7 which I just got a week ago is totally dead after 24 hours, even if I have not used it at all.
Is this normal?
Mine lasts about two days with minimal use.
Make sure wifi is set to sleep while screen off.
Sent from my LG-P999 using xda app-developers app
You need to get something like Gsam from playstore. It may tell you if an app is draining your battery severely, or if apps are waking the tab too much.
Also, Cpuspy will tell you if its going into deep sleep. On playstore as well.
Those will hopefully tell you why your battery is draining. I charge my N7 about every other day....maybe 3. Its mostly used to read books, and sometimes some games. So definitely not heavy use. But standby, about 1 percent lost overnight.

Not normal. Just did over 3 days with 6 hrs screen on time. Turn wifi off when screen is off and make sue you dont have any apps running non stop. Better battery thats is a north app for this. Check the partial wakelocks

Mine takes 2 to 3 usually. Are you using the cable and charger that came with it? If not, that can play a roll. Also, if something greedy is running, can slow charge times too.

Mine drains pretty quick when in use, but if idling, it lasts a very long time. I've seen it not drop 1% until maybe 2-3 hours idling. Heavy usage drains like 1% every 10-15 min.

Same here. Idling last night at 70%. Woke up 7 hours later at 69%(airplane mode) but as soon as I start using, drops super fast.

I think it is MightyText. It seems if I get a text from someone I have not received a text from before it opens a window on the locked screen showing the text and then the screen never goes back to sleep. It stays on until the battery runs out. If I get a text from someone I had a conversation already going with this does not happen.
Pretty weird but it explains why it is totally dead when I would get home from work.
I had poor battery life too,but I've done something that someway fixed that.
I format system etc and reinstall 4.2.2 stock with stock kernel.
After some charging circles here the results
i know if you leave skype on it drains an insane amount of battery...so i keep it logged out now whenever I don't use it
I would have liked to see the main battery status page. See if you did anything with it, or just kept the screen alive for 9 hours? LOL.

When I got the phone, the battery section of settings would estimate 24-26 hours remaining from a full charge. I'm at 90% and it's estimating 15 hours remaining. Anyone else have this dramatic decrease in battery life? My usage of the phone hasn't changed.
The estimated time remaining is an ESTIMATE based on the current usage. (I'm not sure if it's based on the the current usage from a given timespan, since last unplugged in, or what.) The point is that if you leave your phone idle after fully charging, you'll have a higher estimated time remaining. If you use it heavily right after charging, you'll have a lower estimated time remaining.
In other words, it's kind of saying something like "Based on how you've recently been using your phone, you have XX hours remaining." So, change how your using the phone, and the estimate (actually, more of a guesstimate) will change.
Yeah... Makes sense. Phone gets very hot too. Average is 90°...

90F is cool for a phone thats on. your body has an average body temperature of 98.6F. my guess is thst you are giving your battery temp. battery safety is st 60C, which is 140F. your phones cpu has a safety shutdown mechanism that automatically shuts down at 105C, which is 225F.
and battery drain, can be pretty bad depending on the game, is very expected.

What game are you playing? Are you running stock? I would try lean kernel and try to change up the max frequency to see if it helps with the drain while still being able to run your game.
i have wonderful battery life. what ganes do you play, and how bright do you keep your screen usually. i dont play many games, but when i play midern combat 5, it drains battery. but i expect it to, since it heavily uses the cpu and gpu.
