[Q] battery life isn't consistent ? - Nexus 7 (2013) Q&A

Hey guys so the title says it all really. When I first got this tablet ( a month ago ) I was getting 8,5 hours of screen on time and now I'm getting less?
I'm on 4.4 running art. With auto brightness and sync on and I'm at 32% with nearly 4 hours of screen on time
Has this happened to anyone else? Thinking about flashing a custom ROM and kernel

Battery life and sound both for me. They were a bit better on 4.3.

Try Franco kernel. Even the stock settings should give you far better results than you get with stock.

I just got mine a couple weeks ago and battery life has been real disappointing. I got down to 53% with only 2.5 hrs screen time earlier today. Mostly just browsing and maybe 10 minutes of light gaming. No wakelocks or anything. I've got it setup the exact same way as my N5 and my Moto X and I get stellar battery life out of both of them. I can more screen time on my Moto X than I do my N7 and that's downright sad.

Odexed Blue Rom plus Trinity kernel with feew personal tweaks.
Can anyone explain this?I was getting 6hrs of screentime then one day out of nowhere im barely getting 5hrs.I even flashed CM10 and still not even getting 5hrs.
My battery life just dropped one day without any reason,any ideas anyone?
I'm on jellybomb 4.2 and I'm scared to upgrade to 4.3 because I can easily get a day and a couple hours. I don't turn off data or anything. I'm a heavy user

Thanx.Your battery life is real good.Thats how mine was before it dropped.You should get about 5½-6 hrs of screen time,thats the best i seen.
If you flash Trinity7 kernel it might improve it even more,it did for me.
Thanks for heads up on the kernel. I will check it out.

another battery drain question from screen

So late last week I installed liquid smooth and it was working awesome! was seeing -2.3% an hour on my battery drain. but as of two days ago, i'm getting a low of -13% drain an hour and sometimes all the way up to -38% an hour! The charge rate has even fallen from 24% an hour down to a cahrge rate of 10% an hour.
I think the culprit is the screen because it shows at >50% on the battery monitor and in the app "battery drain"
I've honestly searched and searched but can't find a solution to this. How can I pinpoint why my screen is using so much battery (brightness is on auto) even when my phone is in standby most of the day?
Same problem mate, mine is almost 80% drain by screen only..I replaced new battery also in RMA but its also not worked, maybe new update of android fix the problem..mine currently is 4.2.2 JB on nexus 7

Battery life.

I've got to say, battery life is pretty bad with this phone. I bought it brand new yesterday so not sure if it needs to condition itself or not but I came from a LG G2 which has a 3000mah battery, which is slightly smaller than this but battery life was far better. Granted the screen was slightly smaller but still. Is there any Roms that improve battery life but still relatively stock?

Have you disabled all the smart scroll and air gesture stuff? Its useless and hogs battery life. Auto brightness and juicedefender and I can rock it for 2 or 3 days straight.

How long is it lasting for you?
Sent from my SM-N900T using Tapatalk 2
Ya, this sounds bizarre.. I've found this battery to be amazing. How long is it lasting? I've had mine for less than a week and I've used it heavily everyday. I have not even had to worry about charging during the day. 24 hours no problem.
Same here. The first week it was lasting all day but with only 3 hours of screen on time. After some tweaking, I'm currently getting still 20ish hours with 5-6 hours screen on time.

I just don't get it. A lady I know has the sprint variant and I looked at her settings and she had 15 and a half hours off the charger with 5.5 hours screen on and had gps and all the air features on as she's not tech smart so her phone was like out of the box and her brightness was up. I have a custom ROM with GPS, NFC and all the air gesture **** off with the screen at like 35% brightness and I get no where near that.

Also what tweaks did you make? I should rephrase that I get good battery life with the screen off, it lasts all day but screen on time is horrible.
In this pics android os and google play services is destroying battery. The screen time was only like 1 hour and 15 minutes at that time.

I downloaded that we'll see how it works. Like I said the battery easily last 24 hours with medium to little use but it dies fast while using the screen on, I'm seeing others with everything on like GPS, NFC and al the touchwiz things with their brightness up getting far better on screen time than me with everything off and brightness dimmed
Any suggestions appreciated. Anyone try an extended battery yet ?

Stock rooted, I was getting about 24 hours per charge with about 6-8 hours of screen time.

Well my actual battery just must not of been created equal with other phones because after tweaks I'm getting better battery life but only about 5 hours screen time and I have everything turned off with screen on 35% so I don't know :/. I'll check that kernel out.

Well if that is the case your battery life isn't terrible. 24h with 5h SOT and 24% life isn't bad at all. Its not great but it is far from terrible.

I'm just using the stock ROM, rooted with the Kingo Root app. Installed TWRP and then Faux Kernel (hltetmo-faux123-003u)
Be warned, TWRP did trip the Knox counter to 0x1. I had to install Knox Disabler so it would stop complaining.
I was getting about 24 hours per charge, until remembered about the FauxClock app and enabled the Intelliplug driver and Intellithermal manager. About this time, I also installed Advanced Task Killer after going without it for a few years.
Screen brightness is on auto, WiFi and mobile data are both on constantly. I have not had to make many calls though, so I'm not sure how this may affect battery life...
So far, I haven't noticed any decrease in performance. Right now I've been on battery for 30 hours and I have 45% left.

Because of adjustments... Custom ROM and kernel, Screen is at 35%, gps and all location services off, NFC off, all the phones extras like air gestures multi window etc are off, I use greenify to freeze apps and I have most Google syncs off and I'm only able to achieve this. I know a lady who knows nothing about phones and has everything/feature on the phone turned on with full brightness and gets 15.5 off charge with 5.5 screen on time by the time she's at 30%. I don't get it.
Edit- I should note I made this post while stock. Because I heard phenomenal things about this phones battery and was quite disappointed.

Signal strength and the binning of your CPU could be differentiating factor. Reading into other people's experience too much can lead to disappointment.

Android OS at 11% should I be worried?

Hey guys
I got my nexus 7 on Christmas day and as you can see in the screenshot its battery life is pretty good
I would have thought that the android os would go down from 11% to about 4-5% but it hasn't, I'm only on my 3rd charge cycle
What do you guys think ?

No.
With your tablet being on for so long (great battery life btw), it was doing literally nothing other than idling. If you were to use it a lot, playing games, reading stuff, etc., it would be down much lower. Don't worry about it.

I had the same inconsistency at the begining,but,later,it becomes more stable.If you will still not be good with the battery life,you can flash a custom kernel.With ElementalX,I have great battery life with stock ROM values.

That's exactly why I got a Nexus - because I knew it would be easy to root and mod, with tons of ROM choices, haha! But I think I get your point - they are great out of the box without a bunch of bloatware. Just got mine and haven't really kept tabs on battery usage yet, but it has been impressive, both stock and on CM11.

What's your battery life like?

Just wanted to know how other people's battery life is. I got in just over seven hours of screen time today which isn't the best and was wondering if something about my battery was defective or if this was normal. It seemed strange to me because I had my brightness a smidge up from the lowest it can go. Just so that I'm able to get that backlight. So again, what's your battery life like?
Sent from my Nexus 7 using xda app-developers app
5 1/2 hours on screen time, on average. And that's with the brightness almost all the way down, location services turned off, and always listening turned off.
Pretty good to me but I had only about 3 hours screen on time. But it usually last all day and then into the next.

i recently got about 6 hours of screen on with a total of 3 days without charging. i have mine rooted and on slimkat beta 2 4.4.2
That's not bad battery life. I average 8 to 10 hours of screen on time with Wi-Fi on always doing lots of reading but not much video play back and no games to speak of.
This is the best I've ever got out of a single charge.
