[Q] Battery drain 4.3 - Nexus 7 Q&A, Help & Troubleshooting

Hi
I know there has been some topics on this, but no answer.
My N7 has ever since the 4.3 update eaten the battery like it was candy. After 6-8 hour, with no actually use at all, it can go from 100% to 40% and if i look in battery usage, it says that android system has used over 80%.
Its like the system dosent go into sleep mode. I can se when i am at work that the tablet connects to skype several times during my worktime, and its just lying on my table in sleepmode?
It also takes forever to charge with stock charger.
None of the above things happend before android 4.3
Hope anyone has an idea
Brian
PS: If i go to recovery mode and resets the system, will it then use the android version the tablet was born with or 4.3?

I have also noticed that when I leave it asleep and don't use it for a good amount of time, the battery will drop by about 10-15 percent

Battery-life Issues with N4 after 4.4KitKat

I have an LGE Nexus 4 and I just got the 4.4 update a few days ago. I love the update so far, but one thing that really irritates me is:
Battery life! Ever since updating to 4.4, Exchange services is using up more battery than my screen! Other power hungry apps since the update are: Mediaserver, and Android System. (I'm running Nova Launche Prime, that's probably responsible for the android system usage.
I used to come home from school at 5PM with around 35-40% Battery. It's currently 12:45PM and i'm already at 65% :S. Anybody with tops and tricks to help me conserve battery life please do share with my self and the community!
thanks world ( ::cyclops:

I don't think you've provided enough information for us to really tell you. Try getting BetterBatteryStats and then check for yourself what's going on. Sven has fixed it to work on 4.4.
I've experienced the battery to be affected negatively on 4.4 as-well.
For now i turned off the voice command [ok google] which seem to help a bit but still not as good as 4.3.
ITs location services... turn it off and see how much better battery life you get or use device only then check your google services useage
Exchange Push is the issue
I have found that changing my Exchange settings from "Push" to check every X minutes has greatly improved my battery life. It seems to be much more inline with what I was used to with 4.3.
Hope this helps,

Well... I flashed 4.4.2 the other day and I saw my battery plummeting like mad... so naturally the first place I came to was XDA, and saw that a lot of people were having a big problem with battery life.
So I didn't do any battery pulls or anything like that on my N7100, but when the battery went from 85% down to 12% what I did was to turn on everything that I could in order to drain the battery... turned on Data, WiFi, turned off the battery saver etc. etc.
Down at about 6%, I got that alarm with the notification to plug in the charger but I just let it go.
After a while, the phone wouldn't turn on at all... nothing. Nada.
So I plugged in the charger and let it go.
I checked it in about 1.5 hours and it said 100% but the red charging LED was still on so I let it charge for about another half hour and finally the LED turned green.
I turned on the phone and held the power button until the screen flashed three times (About 15 seconds), and let it boot up.
I had 100% charge last nite @ 11:39, and right now on standby (12:45 the next day) I still have 95% on the battery.
Strangely enough, I didn't get one call on this phone all day... but when I don't answer my Note 2, people just try the other number on my iPhone 5s.
Granted, I never leave the WiFi on or data... but I have the stock ROM with all the crapware that it has... but I flashed that French version of KitKat off of that site that I won't mention (But it's that one that if you're not a paying member, it takes you half a day to download anything).
Pretty happy with KitKat stock rom so far, but that first few hours when when I saw my battery sucked dry before my eyes was pretty disconcerting.

SM-N9005 4.4.2 Battery Issue

hoping to get some help...
i have update my SM-N9005 from 4.3 to 4.4.2 through Odin. rooted. with CWM Recovery.
tried probably 3 custom ROM that support 4.4.2 and end up on the Official leaked.Build 4.4.2 ( rooted)
the battery performance is driving me crazy.
on 4.3 stand By mode i used to loose 0.8 per hour now with the same setting same features turned on. i loose 2.3 percent per hour.
on 4.3 screen time with the lowest Brightness i lost 1 percent every 10 minutes. now i loose 3% with same brightness level. 3 percent every 10 minutes.
Android OS and Android System are always on top of screen in the battery Graph. i
media is also on top of the screen in the battery graph.
have tried a lot of solutions and factory reset with no luck at all. ( i have placed the device with Airplane mode with no SUCCESS )
installed a lot of battery analyzer apps did not have a clue who's eating all the Juice.....
any idea how to fix this??

No wakelocks in BBS?
Install Better Battery Stats. Leave the screen off for 1 hour and tell us what the top Kernel Wakelocks are.

Partial Wakelocks are usually caused by apps running in the foreground. There's usually not much you can do about that. If you are actually using the phone, battery will run out. What you need to find out is what happens when you are not using the phone.
Do this:
1) Charge the phone to 100%. Disconnect the cable.
2) Let the phone sit idle for 1-2 hours with screen off.
3) Get Kernel Wakelocks from Better Battery Stats.
Then you'll know what's eating your battery when you are not actually using the phone.
In my case, I get ril-fd, l2-hsic and wlan_rx_wake wakelocks the most. I know the causes, but I can't do anything about them without rooting.

im rooted on Leaked 4.4.2
im losing only 1 to 2 % in idle, way better then JB, but interactive use sucks the soul out of it. rarely pass 30 hours of use.
Im not getting anything

I've noticed the first 10 percent (from 100 to 90) go away fast as hell. Use your phone as you would today, just make sure you have enough juice by the end of the day. Leave it as it is overnight and then post your screenshots.. You don't seem to have any wakelocks so your battery shouldn't be draining.. Mine is going like 1% for 8 hours or something, the problem starts when I turn me screen on lol!
I had this problem on my all my Samsung device
the only solution was to take out the battery for a few seconds
worked for me on
note 2 and 3

i am loosing more than1.5% per hour where on stand by mode... everything is switched of.f im surprised there is no wakelocks showing... ill wait till the end of the day.
its been 4 hour since last charge and now im on 93%..
im assuming the drain is happening due to the bad reception where i am at.
how do you manage 1% per 8 hours that's Awesome (knock on wood) :laugh: .. is this with WIFI and Data on?
i don't understand ... how come i have no wakelock after screen off.. and my battery draining 1.5 % per hour on stand by mode.... and android Os always on top ?
BBM.
And I haven't done anything special, actually you have to do something to NOT get great battery life while idle. After a factory reset, nothing disabled (so G+, G search and all those wake cycles still present) with WiFi off and Mobile Data ON I lost the usual 1 to 2% per 8 hour sleep. The problem starts for me when I turn on my screen, not when it's turned off

What are the causes for wlan rx wake? 12hsic is related to mobile data i guess.

It's caused by broadcast packets sent by other devices in your network waking the phone up. The solution is to install a custom kernel that filters such packets.

[Q] Another battery thread but I am desperate

Hey guys and please dont crucify me. I know there's a ton of other battery issue threads on this forum and on many others but I cant find the right one. I have looked up each and every one of them, about mediaserver draining the battery about the android system and so on. I have done everything each thread said to, downloaded greenify and hibernated most active apps, disabled and froze certain bloatware with titanium backup pro and so many other things. And I think that the battery would be supposed to perform at its best right now. I am not a very heavy user, I just use my phone for music, calls, a little gaming and the occasional facebook/messenger/browser session with either 4G or WiFi. I have everything everyone ever said turned off. Things like auto backup of Google+ and all location services and auto sync. Screen is constantly at 65% brightness. To further prove my point, at this point in this post which took me like 3 minutes to write, my battery has lost 3 percent. I can leave the phone unplugged all night at 100% and when I wake up it will be at 95% but the moment I pick it up and start playing some music or some games the battery goes down really fast. I can even compare it to the battery of my old Xperia S after a year and a half use which was like 7 hours altogether. Battery stats say that mediaserver takes up 20ish% battery and Android system goes over 40%. I really don't know what to do. Do you have any suggestions?
Thanks in advance, George.
you should look at the time it depletes when screen on, if its below 5 hours from 100% downward then its not good. I have noticed the battery still charges past 100%. So leave it an hour after it reaches 100%. I would also recommend using the charger that came with phone. No usb charging for these tests. Dont use phone while charging either.
Also freezing\debloating can be adverse, at least thats my experience on battery life. So I recommend going back to stock full clean with factory resets.
No recovering of apps or app data for these tests. No contamination so to speak.
Also lg roms allow you to switch off services via taskmanager settings, in settings app you can disable what you dont want to use. No need for debloating\freezing etc.
Switch off location settings, gps and bluetooth for this test. Search for carrier iq on lg g2 forum and how to disable it via settings. Switch of cloud storage(dropbox/box etc) and lg backup stuff. Only google accounts, wifi and mobile networks.
Now for the screen on time test, just use browsing apps. No games or music\movies.
Your screen on time should be 6 hours approximately. From 100 to 0. It can be 5-6 hours. If its below 5 then its not good. this is with good network coverage btw.
thats what I would do

Yes I have tried all of the above. Only thing that sticks out is something called 1013 which keeps running and waking my phone but I think it's something about the sound. Next is Android System with many wakelocks and as I said with 30+ % battery consumption. Everything location-wise is off. Actually everything is off. Every setting. Things go to hell when I open 4G or WiFi. Also I have the international model so I don't think there's carrier IQ in my device, or maybe I didn't find it in an app suggested by someone here for that purpose. System Tweaks I think it was.
Could you post a screen shot?

I've had android 4x do this on multiple devices, multiple roms for no apparent reason. Wipe it and start over. Wipe everything. Especially directories with any form of music, sound files, videos... ( Use LG Flash Tool and go back to stock 4.2 for example will do just that )
So the OTA came over to my country and now it seems like BBS and WLD are broken. Can't really do anything to show you the more complex battery stats and can't really say that the battery has improved. Reducing the brightness did have some effect but I am not really fond of having it at such low values. Anything else I can do to minimize the Android System battery consumption? Its bigger than what the screen is using, even when it was at 70% brightness.
Sad to say my first LG G2 just got replaced today & am now running into this problem with the 2nd phone. Its literally night and day battery life performance between both phones.
First phone had 0 issues and by now I'd still have battery % in the 90s. New phone is sitting @ 63% after 3 hours of use (setting up phone, few reboots here there....just factory resetted for the 2nd time to try and clear this etc)
Culprits are:
Google Services
Android Core Apps
Media Server
System UI
Both phones are: 4.2.2
build: JDQ39B
Software: D80110c
brightness (which never was an issue)= 45%
O.P,
has your situation improved or worsened since you've encountered this problem? I'm thinking about sending my replacement back for another replacement

I can now say that the battery life of my phone has improved. But sadlyf the problem was probably some corrupt mp3 files that I moved directly from my old device which forced the mediaserver service to run constantly and thus the android system. :/ I still can say that I think it drains a bit fast when I use it for browsing, Facebook, games and stuff but at least when I check the battery consumption, the only things stated there that make a difference are the screen at ~30-35% and the game which I was playing or for example Chrome. It finally feels like that whatever I use drains the battery and not something else in the background but I don't have that good of an impression for the 3000mAh "beast" battery of the G2. Awesome phone though.

I ended up returning my replacement phone and am back on my original G2 until I can get a proper replacement. I can tell you, the G2 does have an awesome battery life if you get a good phone out the box.
The differences between my first G2 and the 2nd one tmobile sent me are night and day. Get a replacement phone while you still have time.
Should have my new one next week. Just hope it's exactly like my first one.
Ex....been using it all day..I mean heavy usage...and in still @ 75%..and the phone is cool to the touch
The replacement g2 would [email protected] 36-37% by now and running hot

You're on 4.2.2, not 4.4.2 when you have the 1013, is that correct?
Try rebooting when the volume is on, rather than rebooting in quiet/vibrate mode.

The OTA came to my country some days ago. Still the battery feels kind of small. Is it normal to lose 1% every ~1-2 minutes on 4G browsing? With nothing else on. No gps no G+ backup no anything.

Galaxy S5 plus battery drain (G901F)

Hello everyone,
I received my S5 plus about 4 weeks ago, (After an overheating LG G3 and a unresponsive Oppo Find 7a i took this one) and all the time I have had a battery drain.
The first one was fixed with a factory reset.
After that the Android System and Android OS were draining battery. At one moment it became to mutch, so I did an reset again.
It was normal for a day an a half, after that the phone was awake/active all the time.
Now I still have the same thing, Android OS and System (Espescially System) are using a lot of battery.
here you have some samples
No photos because im still new
But Gsam says the Android System is using 40% and The android OS is using 20%
Al the other apps are using below 2%
Samsung battery says the System is using 10% and the OS 8%
I am running Android 5.0.2
Anything I can do? I disabled all of Samsung bloatware and other thing but it doesn't help.
I am not rooted and i dont want to. (Lose warranty)

its terrible - pure system without any apps installed and as i said 30% down over night - most uses Android System (or something like that) - i cant check now as im flashing back to KK again at this moment.
EDIT.. my pc died in the middle of flashing..... it is a bad day... download mode is still working, reflashing with kies.........
this problem started because of stupid KingRoot.. i downgraded to KK because i wanted to try if it works on KK...

after last night i lost only 3-4% so its ok, but i didnt use other apps than system so android and system are ~20% in battery stats.
i will test this KK for few more days but i feel it will be ok now.
as i said earlier, phone couldnt go in to deep sleep as much as it should, 300Mhz was used even when phone was idle - now it enters deep sleep for almost all idle time

Note 4 Fast Battery Drain

Hi,
Not sure if this is in the right section so admin please feel free to move.
Ive googled my problem and had a bit of a read but dont really get any solutions.
Ive noticed a serious battery drain since upgrading to 6.0.1 - maybe it happened on the previous version however ive just seemed to have noticed it more since i did the update.
My battery doesnt last very long. It will show 100% in the morning. If i dont use it, it can go down to about 80% within an hour or so. If i do use it then im using apps like gmail, whatsapp / sms, short phone calls, some other apps but im not on them for very long. I normally close all apps that are running in the background.
This morning it was 100%, ive used it as described above and its on 57% and its not even dinner time yet...
Ive checked the battery usage and top of the list is " Cell standby" with 48% usage showing power used is 1530mah - which is alot. The next is "my data manager" (an app to manage data usage) showing power used is 485mah (alot less!). Ive attached a screen shot.
Ive also noticed that once the battery gets to around 30% it drains even faster. I find myself using power saving mode when it gets to about 20%. It still seems to drain at a similar rate. Maybe slightly slower.
Any ideas on what i can do to recover battery time without buying a new battery. There seems to be a few topics online relating to battery drain when updating to the latest android version.
Thanks

This morning it was 100%, ive used it as described above and its on 57% and its not even dinner time yet...
Ive checked the battery usage and top of the list is " Cell standby" with 48% usage showing power used is 1530mah - which is alot. The next is "my data manager" (an app to manage data usage) showing power used is 485mah (alot less!). Ive attached a screen shot.
Ive also noticed that once the battery gets to around 30% it drains even faster. I find myself using power saving mode when it gets to about 20%. It still seems to drain at a similar rate. Maybe slightly slower.
Any ideas on what i can do to recover battery time without buying a new battery. There seems to be a few topics online relating to battery drain when updating to the latest android version.
Thanks

Factory reset might help a lot.
Dont really wanna have to do a factory reset if i can help it.
I forgot to mention i also cleared the cache in boot mode

I had same battery drain issues when i updated from lollipop to Marshmallow but after doing factory reset everything is better then lollipop and doze feature in 6.0.1 works very well. I leave my phone at night about 9 hours and not drain even 2% battery and i got 5 hours scrern on time .
try factory reset+wipe cache from recovery and use atleast 3 days to doze feature work properly.if you have same drain issue then it's a bad battery.this is the only solution so far.
Battery pull?
