I keep my location set at "battery saving" the vast majority of the time. You can hibernate google search with Greenify if you don't rely on google now cards very much but like I said I don't use google now and google search will still start up occasionally, it isn't a big battery drain for me. I use Dolphin Browser as my "default" browser with the adblock add-on available in the Lab option. I use Feedly and Press for different rss feeds and see zero ads when I open an article in the browser from either app. Also, if you watch much youtube the xposed module youtube adaway works awesome!
[Nexus 7 (2013) General] jk8260:
There is a module...

There is an xposed module named 'disable location consent' to prevent google location consent, I use it to only turn on location for apps that need it with tasker, works flawlessly.

How is everyone's battery life after 4.4.3?

I have the 16 GB wifi model and I'm on 4.4.3 for a week now.

At first the battery life was ok. Pretty much the same as 4.4.2. But now after a week I'm losing 8% at night in airplane mode... First i lost about 2-3%..

This update seemed to make the battery life worse..
[Nexus 7 (2013) General] :
Why is that considered bad battery life, that's amazing especially for kit kat, I'm running 4.4.4 Franco Max under clock and undervolt and guess what 4 hours screen on time with prob 10hours running time wtf
[Nexus 7 (2013) General] just lou:
I'm running stock 4.4.4 with ElementalX Kernel with the CPU overclocked @1.7GHz, and the GPU overclocked at 450MHz. I get 9-10 hours of screen time usage. I lose about 2%-4% overnight during deep sleep.

Bro what are the governers
[Nexus 7 (2013) General] goughymachine:
Can't complain about mine. On stock 4.4.4, haven't bothered rooting it since the update and not running greenify and haven't frozen anything in TiBackup. Granted there has been no media playback as such. A tiny bit of YouTube. But mostly reading and browsing. Always with wifi on.

hi plz help

I have a brand new N7 but i think the battery really sucks.it gives me max of 6 hrs of active use.i have disabled all the Google services i don't need. Haven't rooted. Running on 4.4.2.

I wanna know if i should replace it. Please help.i played a 1080p movie for 1hr 33 min on full battery and 10%brightness and the battery consumed was 32%. is it normal?
[Nexus 7 (2013) General] wantabe:
6 hours of active use, does that mean screen on time? If you're doing a crap ton of gaming, youtube and watching videos 6 hrs does not sound unreasonable. Most reviews show an average of around 9 hrs with "Web Browsing." The total configuration that you have setup on your device will play a big part. One example would be using full hardware acceleration for video playback which can and probably will affect battery life. I've never used MX Player (which I'm guessing you are using based on your screenshots), I've only ever used VLC on my Nexus devices and with VLC using full acceleration or decoding acceleration it does make a difference in battery life so I leave VLC on "Automatic" and it works fine. And... VLC has a built in equalizer and preamp and it's free (no ads).. There are a lot of settings that can improve battery life. Wifi Advanced Settings like network notification, on during sleep, always scanning. Location Services off or using wifi only (Mode: Battery saving). The device only mode (gps) eliminates all of the NlpWakeLock and NlpCollectorWakeLocks which "might" might make the "Device only" option in location services a good option depending on your installed apps and if those wakelocks are a problem. A lot of apps you can set a default location, especially weather apps. Don't use apps with ads! The ads use up bandwidth which uses your wifi and cpu. There are a lot of things that can be done to maximize battery life without having to be rooted. That said I'm rooted, using stock voltages, stock 4.4.4, overclocked (1728/450) and with mixed usage and wifi and location services on I usually get around 9 hrs sot. If just reading (kindle app) with wifi and location services off I get 18+ hrs sot. My brother also has a N7 and a N5 without root (the horror) and can get fairly close to my screen on times. So it can be done! Being rooted gives you more options to use but it can make it harder to update if you don't know how to use the sdk. I think you can improve your battery life you just need to experiment with your configuration and apps used.

Try using ART and see if it helps. My battery life was pretty good without it, but when I tried out ART, my battery lasted a few hours longer.

It's definitely worth a try.
[Nexus 7 (2013) General] Arthedes:
I guess it is time for me to root my device already. Any tips on how to backup all of my data and apps?

Ive read about the elementalx kernel. Is it possible to run it while using the stock rom?

Once rooted and running a custom kernel, can you still run the stock rom and update OTA, while keeping the root and custom kernel active?
[Nexus 7 (2013) General] Arthedes:
I am running ART aswell. Battery life is a little less crap indeed.

What is life without art? :p
[Nexus 7 (2013) General] Mysterion1:
NFC and GPS disabled? When flashing a new rom/update then it is often auto turned on...
[Nexus 7 (2013) General] LinearEquation:
I run an Odex ROM without art that is faster than running Art imo.

I run sinless ROM with elementalx kernel and I get great performance and battery life, are you running a custom kernel that might help
[Nexus 7 (2013) General] PlayDude77:
Wow, you guys are getting a lot of battery life. I'm disappointed with what I got today. I basically just used my tablet to browse the Web, stream music via Spotify and chatting, and I don't think that should take such a big toll on my battery. :/

The screen's brightness was at roughly 50% most of the time. I'm currently using the stock rom 4.4.2 with the latest ElementalX kernel.
[Nexus 7 (2013) General] bcvictory:
How much screen on time did you get?
[Nexus 7 (2013) General] PlayDude77:
Sorry, forgot to mention that. I got 5 hours and 40 minutes.

Funny thing though, a couple of weeks ago before I rooted and was still on version 4.3, my battery lasted more than 7 hours under not so light use. As you guys said in this thread, KitKat doesn't seem too battery friendly.
[Nexus 7 (2013) General] bcvictory:
I normally get 6 and a half hours. People are getting 8+ normally though. I don't know what I'm doing wrong! Haha
[Nexus 7 (2013) General] PlayDude77:
Maybe your clock speed is too high? That may be my problem, I think.

I installed the kernel with the recommended values tbh.
[Nexus 7 (2013) General] cobyman7035:
thats your killer there! use 10-20% max only, it will give u 2 hours SOT more at least
[Nexus 7 (2013) General] ncguy68:
Getting excellent battery with Slimkat ROM and Franco Kernel. Average between 11-12 hours screen on time.

Soo does anyone have any other thoughts on this matter?
[Nexus 7 (2013) General] sokinso:
Maybe he just let the screen on for many hours with minimum brightness....no other explanation for me
[Nexus 7 (2013) General] Arthedes:
Ive deleted avg, lets see how that goes

Ive seen many people reporting 10 hours of battery life or more with 4.4.2 and art with casual use like browsing and fb and youtibe with a stock rom and kernel
[Nexus 7 (2013) General] juliatan:
Copy paste of my reaction to other topic a few minutes earlier concering batterytime. (http://xdaforums.com/showthread.php?p=49281923)

------------------

Have not tried ART yet, because Xposed is too important to me. Really hope it wll be made compatible or there comes a solution for some of the modules such as Gravitybox and best battery saving app ever Greenify.With extra functions Greenify (works only with Xposed) almost everything including Google apps and non important system apps Greenified.

With Dalvik now I have 10 to often over 12 hours active screen time. Among others browsing, reading books and rss, music via cloud on bluetooth, little bit video, etc. Brightness during day 25 to 50 percent and evening/night 10 to 25 percent. All syncing off. Wifi off when screen off (will finish downloads and rss when screen goes off). Use two widgets (Dashclock and One More Clock). Avast always running. Nova launcher instead of stock. Etc. After night sleep or workday of around 8 hours standby only uses about 1 percent battery.

After OTA update 4.3 to 4.4 my batterytime was a few hours worse. It became better after clearing cache partition via stock recovery. Since OTA 4.4 to 4.4.2 batterytime became as good as 4.3 again on my Flo.

Concerning battery time I am very happy, but I will keep a close eye on development ART and alternatives Xposed and modules.

System: rooted fully stock 4.4.2. I use GSAM for battery stats.
[Nexus 7 (2013) General] Arthedes:
I am now rooted and using greenify.

Will charge overnight and post results when my battery is empty. Been playing around with it and looks good so far: the battery dropped only 10% the past 1.5 hours with the screen on
[Nexus 7 (2013) General] ncguy68:
It was routine daily use....email, web browsing, several hours reading, XDA app,playing Words, Candy crush and about an hour of streaming video over home network. I keep brightness about 25%.

I use Franco Kernel and I have it underclocked back to 1500. This ROM and kernel combo give the best battery I've ever got on any device.
[Nexus 7 (2013) General] dakunclear:
Ya battery is considerably worse in stand by since 4.4
[Nexus 7 (2013) General] Arthedes:
So this is my new result. These results are with the nexus 7 in the following state:

Unlocked bootloader

Rooted

Stock android 4.4.2 rom (KOT49H)

Stoch kernel

Running ART (Since the latest patch, greenify is compatible with ART!)

Using greenify to hibernate the apps shown in the screenshot

Brightness at 15-25%

WiFi always on, even during sleep

Email synced once per hour

Facebook synced once per hour. (I greenified this when i was at 80% battery)

Nova launcher instead of stock

Running the default clock widget and the default email widget

Bluetooth off

NFC off

I let it download all my apps before i charged my device to 100% and started testing. I also greenified any unneccesary app before i charged. The following results are thus as it would be during normal use, when everything is set up already.

What ive done during this sycle:

Browse the web

Tweak the nova launcher to my liking

Downloaded some wallpapers and changed the wallpaper a lot

Streaming ~ 15 mimutes of youtube

Steamed 1 hour of video through the browser and mxplayer (hw decoding)

I didnt play any games

I was half an hour total on facebook. When closed, greenify would hybernate facebook. This is true because i didnt receive any messages until i reopened facebook.

The screenshots of the ram usage and greenify are representative of 90% of the time the tablet was in. Some apps like facebook and mxplayer will be pending when the app is closed. They will then be hybernated when the screen is turned off for a certain time.

Notice there is not much screen off time. Yes, I spent 6 hours staring at my device's screen yesterday.

Notice the drop from 21% to 14%. Now this is strange. When i went to bed, battery was at 21% with 6 hours OST. When i woke up, it was at 14%. You can see that when the screen was turned off, it leveled at 21-21%, then dropped to 15%, and then leveled out at 14% again. Also upon restarting, battery dropped significantly to 7%. I think this may be due to incorrect calibration of the battery. Perhaps calibration will be better at the next cycle.

As you can see, there are a lot of system apps running in the background, such as gallery, calendar, keep etc. I dont have the donation version of greenify, which lets me hybernate those. Would it be safe to hybernate those apps?

TL;DR: unlocked, rooted, stock rom and stock kernel, greenify, ART. Casual use. Result: 6 hours and 36 minutes OST.

What do you guys think? I dont think this is compareable to results other members have posted with similar setups (10-12 hours OST).
[Nexus 7 (2013) General] Arthedes:
Do tou manually enable and disable your wifi? When i have it set to off when screen off, my battery meter says its still on when the screen is off.
[Nexus 7 (2013) General] ncguy68:
No, I have it set to turn off with the screen. It doesn't make a huge difference....maybe 2% over a six hour period.
[Nexus 7 (2013) General] Arthedes:
How do you know it is off? I do see that it is reconnecting when i turn the screen back on, but on this screenshot you can see that the battery meter registers it as if it is on constantly. (This is only from the past 12 mimutes, but when i leave the tabket off for 6 hours, there still is a continuous blue bar under wifi)
[Nexus 7 (2013) General] ncguy68:
I've had the same happen before..its usually an app keeping the wifi active. It takes my Wifi 5-15 minutes to turn off after the screen turns off...it doesn't happen right off.
[Nexus 7 (2013) General] Arthedes:
Youre right, it works for me aswell, probably thanks to greenify!
[Nexus 7 (2013) General] jalchemyst:
It seems that there are 2 types of nexus'. One group consistently get amazing battery life, ie (SOT 10ish hours) and the other who no matter what only seem to get around 5-6 hours?

Unfortunetly I'm in the second group. I turn auto sync off, have my brightness nearly all the way down, bluetooth, gps all off. My idle time is pretty good, only about 1% every 8 hours. I've done everything to conserve battery as well, ie Greenify, slight underclock and undervolt on Elemental X kernel. I even switched to ART to check if there was much difference (for me, there wasn't much).

Does anyone think it's a faulty battery? I mean 6 hours SOT is still pretty decent.....
[Nexus 7 (2013) General] Arthedes:
I noticed that too and im beginning to think that it might be hardware related aswell. However, I've owned another nexus 7 2013 for 10 days, until i decided to return it because it had a dead pixel, which had similar SOT. Actually when both stock, the SOT was pretty much identical. Now this is not scientific at all to say, but i think it is highly unlikely my SOT is this way because my battery is worse than other's.

I now have a lot of system apps greenified and will see how that goes next charging cycle.
[Nexus 7 (2013) General] jalchemyst:
I've tried a few different roms, PA, omni, cleanrom, aokp (all nightlies) and it's roughly the same. I'm on 15% atm and have only used it for light browsing, some youtube and mostly reading books. On a side note, I'm using gsam monitor and my apps are using about 50% of my battery, with my browser, sleipnir, using about 15% of that. Is that normal?

I emailed ASUS about the battery life and they did say I could book a time to get it looked at, but not quite sure if there's anything that they will find, I'd be interested to see whether Greenifying the system apps will work.
[Nexus 7 (2013) General] Arthedes:
How much screen on time have you got?

Currently ive greenified google play services, google search and google maps aswell. Now the wifi actually goes off when i turn the screen off (after 5 minutes or so)

Ive also installed the elementalx kernel, but this has no impact on wether my tablet decides to wakelock.

These screenshots are with a few minutes sot. (Plugged it out this morning and just got home from school) so basically it now drains next to nothing when the screen is off, compared to 5% overnight previously.

Will update on screen on time
[Nexus 7 (2013) General] Arthedes:
Battery (%): SOT (Hours)

90:1h 20m

80:2h 00m

70:2h 55m

60:3h 15m Standby time is very weird: sometimes it drains literally nothing, and sometimes 1% every 2 hours...

50:4h 00m

40:5h 04m battery derped out and went up to 42%, now at 5h 15m at 40%

30:6h 00m the battery app doesnt count my screen on time any more. My battery life is so good now that i broke it!

Hey man, are you able to run ART while Greenify and xposed is installed? Because when I installed xposed and re-booted, it changed automatically back to Delvik, and now when I try to change back to ART and reboot, it doesnt change. It stays on Delvik. Im scratching my head.
[Nexus 7 (2013) General] Arthedes:
Hey bro, i dont know if ive got xposed framework installed or not. At least i didnt specifically installed it! What i did was rooting, installing the busybox stuff and then enable art. After that i downloaded greenify and it just worked.
[Nexus 7 (2013) General] neo5468:
Yeah but you said you greenfied google play services and for this, you need premium key of Greenfied. When you purchase it, it asks you to install xposed, so you can install framework and enable Greenify. After that, you can activate "experimental features" of Greenify, like system apps (google play services, youtube, chrome, google maps, etc).

I was digging through xda search and found this:

http://xdaforums.com/showthread.php?t=2605070

So if its confirmed that ART is not working, are you sure you have your turned on?

The question is, shall I run ART without xposed and Greenify, or DELVIK with Greenify, xposed and those experimental features. Which road will give me better battery performance? I think I will stick with Delvik + Greenify since the real battery eater are google services+apps (looking at you, chrome!). I can disable those stuff and therefore, get better battery performance despite the fact that im on Delvik, not ART. What are your thoughts ?
[Nexus 7 (2013) General] jalchemyst:
I finished up with just over 8 hours last night and most of that was on google books reading.

Reading through the different forums, some people experience a increase in battery life/performance, while some don't really see much of a difference. Probably best to try it out yourself.

I had to flash the uninstall zip file to properly get rid of xposed and that let me switch over to art.

Not quite sure what to do anymore now. Majority of the time, I use it at home so I guess in the end battery life isn't the most important. And I don't want to go through the hassle of warranty. But I just hate the feeling of getting a sub-par device lol.
[Nexus 7 (2013) General] neo5468:

[Nexus 7 (2013) General] jalchemyst:
Well I did some browsing and was on Youtube as well, albeit not a lot, but wow. That is some insane SOT.

I was just coming to terms with my shoddy battery life as well. Thanks a lot dude! LOL.
[Nexus 7 (2013) General] sizzlers:
Personally iv never achieved full 10 hours cause im mostly gamer and got use to spend whole battery under few hours so i math it with gaming hours.Bougth device couple of weeks ago and different kernel+rom scenarios made me twinkle upon the battery life.So for best battery and performance i stand behind franco latest kernel.

When device got root it and put franco kernel plus clean rom and got 5:30h of pure gaming.Only gaming and keep in mind i didnt knew kernel default was clocked at 1,7ghz.If u underclock it imagine the life.Also i had Art switched on cleanrom no matter it was deodexed.

Newest paranoid beta 2 that i tryed in gaming performance good but battery life is poor for now.

After cleanrom i needed somethink with little bit of customization and went to slimkat plus franco kernel wich perform beautifuly.I cant get the cleanrom results but im stil in dillema wich setup to go and im leanin towards first setup.

With slimkkat+franco for 22 hours of standby battery from 100% dropped only 3 %.I was wow.No other usage only idle-ing

You are not alone. The best ost I can manage with my Nexus is 7 hours. And everyday I go to xda to look for a cure and all I ve gotten is the depression after looking at other people's ost (18 hours? Are you kidding me?). I guess it has something to do with hardware to get this widespread among nexus 7 devices.
[Nexus 7 (2013) General] jalchemyst:
That actually makes me feel a lot better about my device lol.

Think I'm just going to factory reset it, unroot, lock the bootloader and hand it over to ASUS. Worse case scenario, everything stays the same.
[Nexus 7 (2013) General] neo5468:
People you did not read my post correctly. I clearly stated that I was using tablet on low brightness (5-10%) and most of the time I was reading book in kindle app. Thats how I got those insane 18 hours. Tablet wasn't using cpu or gpu or anything!

On normal usage, 20-30% brightness, some browsing, watching a movie or tv show on medium-high brightness... I get 5-7 hours SOT with Delvik, stock rom and stock kernel. Everything stock. And i'm pretty happy with results. Everything above is not stock or people were using tablets for reading, that's how they farmed those insane SOT numbers. Nothing is wrong with your devices people, stop being so paranoid.
[Nexus 7 (2013) General] Arthedes:
I used another free app to convert google play services to an user app so i dont have to pay 3 euros for an app's function that may or may not improve my battery life.

When an app is converted to an user app you can just greenify it using the free version.
[Nexus 7 (2013) General] Arthedes:
Holy balls.

What do you have greenified? What apps do you have syncing? What rom/kernel??
[Nexus 7 (2013) General] neo5468:
Read post above for clarification why I got 18 hours.

I have everything stock (kernel+rom), no greenified or any other battery app. I just have root on it. That's about it.
[Nexus 7 (2013) General] alasholyweek:
I met a guy when I just bought my Nexus. Doing the basic stuff, listening to music, web surfing, etc. I got 6 hours max and he got 9 without even trying. And yes, I keep my brightness around 5%. After installing a custom rom, kernel and greenifying all the gapps, the best time I can get is 8 hours. Even without gaming and watching videos, I have never gone further than 8. So imo, that is anything but fine.

That you think of us as being paranoid is understandable. I have seen a lot of guys complaining. Over here in my country it isn't as easy to return your device and get a new one, so this is the only place I can go to.
