Horrible Battery Life

It would seem that after I installed the AT&T update to dumb down thr search on my phone, my battery life has been terrible. Yesterday it was down to about 30% after only 4 hours of light use with the processes "Android OS" and "Cell Standby" taking up the most battery. I can't even get through the day with this phone. Some help would be much appreciated.

After any update, give it a couple days to level out. Until then, just carry an extra charger and plug in when you can.

The update was installed at least a week ago.

In that case, backup everything and do a factory reset when you have a fully charged battery.

Alright I'll give it a shot. I needed to do that anyway as my clipboard no longer works and consistently crashes. :/

I did a factory reset a few weeks ago and that solved it for me.

Do you have any specific methods for backing up a phone that isn't rooted? I've got nova backed up, but I would like to make sure everything else is too.

Are you receiving push email? that was the major drainer for me. apparently the android email app has a bug.
Regarding clipboard...delete everything in data/clipboard; force close the 'test service' app and then restart your phone

The best method would be to use titanium backup but since your not rooted I don't know what options you have except to use the google backup but that ain't to good since its only app data.

Hi all,
Since getting the phone from day one, I really never had a problem with the battery. Lately however, I've noticed a significant drain in battery over night. I tested the drain a few times over several nights, and even put my phone into "airplane" mode to help save battery.
Below are my results from going to sleep at 1:30am with 100% battery power and in airplane mode and waking up at 9:30am the next morning. I get a 12% decrease in battery over night for doing nothing over the course of 8 hours.
The only thing I've noticed differently is that Chrome is starting to use battery which is odd because I rarely use Chrome to begin with.
Any ideas to help this? What should I do?

Yeah I've noticed a huge jump in Android System usage since I flashed the UCLG1 update.
Currently
18h 27min on current charge
screen on 1h 22min
Android system = 51%

DudeWatsThat, thanks I'm going to give it a try and see if uninstalling Chrome changes anything. It just boggles my mind that in airplane mode over night it would drain the battery 12%

i second that problem about Chrome. I think it is a bug regarding the builtin flash code. my battery was great until i installed Chrome then it got really bad. I uninstalled Chrome and my battery life jumped up big time. huge different. too bad i really like Chrome but no go right now

Not sure if it's the same issue, but I had some problems with battery life in Chrome until I disabled Tilt Scrolling under Developer Options in the Chrome menu.

my battery life is great even after the update

Worst battery drainage profile I've had

Hello xdadev!
I was hoping someone may point me in the right direction (I have searched but have not found this particular issue in the forums).
After an 8-10 hour charge using my samsung wall AC adapter (1 amp) I unplug my phone and check email, send a few whatsapp/line messages, browse the internet on chrome. the very FIRST app I use causes huge battery drain. For example if the first thing I do after unplugging the phone is use whatsapp then whatsapp causes 70-80 percent battery drain over the next 15 minutes. As an example this morning I used whatsapp first on my phone, then chrome. Over the next 15 minutes my battery drained from 100 percent to 79 percent (in 15 minutes!). The phone also gets warm during this time. When I check my drainage whatsapp is at the top of the list next to screen and my screen is at the dimmest brightness.
The next part is variable. After about 15-20 minutes of constant use the rate of discharge changes to a slower rate. Easily can tell on better battery stats and the native battery monitor software. Sometimes I can curtail this super rapid discharge by force closing every app i start for the first time after unplugging the phone and restarting that app.
I don't know of any other i747 user who goes from 100 percent to 79 percent in 15 minutes. Would appreciate some insight!
Btw i'm rooted running CM 10.1.2 and here is a graphical representation:

EDIT - Update 8/17/2013 - rebooting into cwm and wiping the cache and dalvik cache appears to have improved the battery situation. Drainage is more reasonable.

With the phone idle now for the past hour I have gone from 75 to 55 percent battery. So in the less than two hours my phone has been unplugged it has drained about 50 percent battery. I dont' see a ton of wakelocks either. Now as time has passed you can see the INSANE battery drain when i first unplugged my phone.
Here are some relevant screenshots:

So what happens if u unplug at 100%, and then just leave the phone alone for a bit? Try greenify from the market, it's free and its awesome!!

I use greenify, and i agree it's awesome!!! I don't greenify whatsapp however because I wouldn't receive notifications when I get new messages.
If I leave the phone after I unplug it, sometimes it discharges at a slow rate, sometimes at a fast rate. It's tough to predict.
One thing i've noticed is if I charge it by usb port on my computer it seems to hold the charge better and I would never get this kind of spiked discharging.
Maybe it's a hardware issue?
I've had to charge it several times in the car today (and on a long drive as well) ... check out that loss of charge when I woke up today!

Yea, I'm kinda at a loss bro. Unless your phone/battery is older? Might be time to replace the battery and see if that does any good? Wish I could be of more help...

Clear cache and dalvic cache. Could be a Google app constantly chugging like maps or something.

from what I have heard, google apps can sometimes be very sneaky and hard to detect. its worth a shot

Turn off data if the drain stops you know its an app that's locked into using your data and causing high wake locks. Apps that show low to no data usage when you know you use them usually show up in android is as background for some reason. Ie (YouTube). Really just freeze one app at a time to test them

Take out your battery lay it on its side, if it spins like a top it's bad and needs replacing, seen many different samsung phones do that.

LOL a battery within a phone within a battery within a phone.
Interestingly, I booted into cwm and cleared cache and dalvik cache ... charged up back to 100 percent and now i'm 20 minutes in and at 98 percent ... I guess I have to do that every time i unplug?

Nah it might have just been a one time thing and you might have fixed whatever app was doing it. If it happens again. Redo the clearing. Slap that thanks button! And put a solution in op for future people!

High battery drain for a fresh reinstall 7.0 in idle for no apparent reason

Hello, people!
So, on 6.0.1. stock ENcrypted it was like this:

about 5% lost per night
WiFi always on, whatsup, maildroid checking one imap mailbox for every 120 mins (set to wake up the phone), ok google OFF, now cards OFF, backup-ing OFF. Steady about 5% (4-6%) per night.
Now, I flashed factory image 7.0.0. everything stock. Then I flashed boot.img with disabled encryption and formated data and cache. Everything is as it is described above expect for the maildroid has NOT been even installed yet.
And that's what I get second night in a row (rebooted, cache wiped from recovery mode before leaving the phone):
23% eaten for doing ABSOLUTELY NOTHING!
What even worse, even android itself does not know what it was doing that it ate so much battery because the percentages does not add up for the whole drain.
After so many time invested into this phone for getting pure stock 7.0 unencrypted I just feel exhausted and want to throw this phone out of the window.
I'd appreciate a right direction for figuring out what drains the battery.

Yeah battery blows with nougat. Significant Google play services drain mainly bet scheduler. Had somewhat similar with MM but was able to really calm it down with Power Nap, bit since Xposed is not out yet for N....I'm nandroiding back to MM too.
Sent from my Nexus 5X using XDA-Developers mobile app

I downgraded to MM, and it became normal. The next day I missed the quick switching between the last two opened apps and I flashed N again))
Actually, this night it drained 8% what is kinda OK. What I additionally did was that I disabled under google account sync everything except for the contacts and calendar. Also I activated data saver and added only whatsup there. Wifi was on all night, but he phone did not seem to be waking up during the night at all, what is good because I didn't need it to be doing anything except for idling in case someone calls for emergency. So, I guess after some hard tweaking and disabling things I can cope with N, but mostly for the sake of awesome interface features.

Just give it sometime...things are settling in...so a lot of time play services and stuff also go crazy...also apps are getting updated as well...give it a week or so...things will be better

I had this sort of issue on DP5 after a while but clean flashing MM stock and then re-OTAing to N seemed to fix it for me and I'm back at 5-6% overnight.
I honestly think there is a bug in there somewhere, whether its Google services or what i've no idea as my battery stats didn't seem to add up to the drain I was seeing. I had a similar weird drain before on MM too which a wipe sorted out.

give the system some time to settle in. i upgraded to N the day it came out and after giving android a few days i recognize no major difference in performance or battery life, even though things like Force Doze are incompatible now.

That's a new data saver feature being turned on. Setting -> Data usage -> Data Saver option there

I went back to MM not because of the idle drain, infact, I had no drain but the SOT sucks... Like 2-3 hours instead of 4-5 on MM. Maybe I'll wakt until Xposed it compatible again...

Hi, I don't mean to hijack the thread, but I posted about an issue with the screen, which is battery related as well. Actually when idle I have almost no battery drain (up to 2% per night). Could you take a look at this thread regarding the issue: http://forum.xda-developers.com/nexus-5x/help/nexus-5x-android-7-screen-battery-usage-t3463591
I have screenshots prepared (even worse than what I've already described), but as already mentioned I don't have enough posts in order to be able to post them here.
Is this an issue with the screen, battery or OS? The device is new with the OTA Nougat update.

Battery Drain from "Kernel (Android OS)" and "Android System"

Not sure when this started but I'm now dropping about 20% of battery per night and when I look at GSam battery monitor it seems to be due to :
- Kernel (Android OS)
- Android System

I'm running S233 Deodexed, rooted and I've already optimized everything I could with Greenify and that seems to have worked ok looking at the Gsam stats.
Anyone know what might be going and what to try to curb that battery drain ? Thanks !

i am having the same problem..... since last two weeks.

Not sure what to suggest, I ended up wiping and restoring with Titanium and it's definitely improved things, something must have gone "wrong" somewhere...
I still find my P2 to be not very frugal (not as much as say my old Moto X) but with the huge battery it's impossible to drain it in a day and I'm never that far away from a power source, so...

Thanks for reply. I dont want to wipe and do restore. If you have to do it only once then its ok but everytime... Not good..
I post the same issue in different forum, will update if i get something..

"The *backup* wakelock is activated once you plug your device into the charger and it continues to manifest no matter what you do because it is stuck in a buggy loop, only reboot will fix it temporarily until you charge the phone again.
Through many trial and error experimentation I finally found an easier fix than rebooting every day.
1- Reboot the phone (just once to fix the wakelock, or the next steps won't work if it's already activated)
2- Before charging the phone, turn off WI-Fi & Google Backup
3- Fully charge the phone
4- Unplug the phone
5- Turn Wi-Fi & Google Backup on again
6- ???
7- Profit!
The culprit is Google Backup, and the bug is activated once the device is plugged into the charger and on Wi-Fi, but if it's turned off before and during charging with Wi-Fi off it'll not be activated.
But if the wakelock is already activated, it won't go away even if you turned backup off.
The Wi-Fi is a strange case, I once rebooted the phone, turned backup off and charged the phone with Wi-Fi on and I had the wakelock. My guess is even with backup off, some logs will still try to backup when Wi-Fi is on (Wi-Fi passwords maybe)
4th day without the Android System battery drain and both my Nexus 6P and Galaxy S7 Edge doze properly now.
Hope It'll help you as it helped me. "

Question Very absurd heating issued not fixed + battery drains fast

I've had this issue ever since I restored whatsapp backups, deleted everything regarding it. Now the phone heats up noticeably with NORMAL usage, and the battery drains way faster than normally. I have done a few factory resets, cleared cache then finally flashed stock rom with odin, using nand erase option.
But the issue still persists.?! Anybody more technical than me? Been through the whole internet searching about this issue and no avail, and visited service center 2 times where they claim it is an app when clearly it's not.

What does it say for your battery usage? Settings->Battery and device care->Battery->(tap on graph)
Also you said you've done some factory resets - it can take a few days for the adaptive battery usage to optimize itself after a reset.

Yes, I installed whatsapp way back in march and this caused the problem to arise. Haven't touched it ever since.

Obviously TikTok using a lot of battery because I've been using it a lot. Installed or not, heating still occurs when using other apps. Neither is it microG, that has been using battery today unrelated to the draining issues.
And regards to the factory reset, they were done way back in march as well. I did wait until the optimization to sort itself out but nothing ever seemed to change. I had done a reflash through odin as well, making sure the storage gets completely wiped out.
The apps aren't at fault though. Before I had installed whatsapp, these apps you currently see did not have such massive draining or heating issues until installing wa. Neither did the issue go away after factory reseting or flashing the stock rom. All of this happens in safe mode too, I am not sure where to even begin with.

Ah ok, I see. Yes, that's more than enough time since your reset for the adaptive battery to figure things out.
How much is the drain overnight when you're sleeping?
Are you mainly on wifi or cell data? How strong are they for you?
Another thing you can try is dark mode and see if that helps at all as our screens use less power when showing black. I don't know how much of an effect that actually has though.
Also, if you haven't already, set your screen to 60Hz instead of 120Hz.

Overnight drain is nonexistent. And I am typically on wifi when at home, outdoors using data. Both have full bars so I am sure it's not them.
Been on 60Hz the whole time, I dislike 120Hz
I've had this same problem on my previous S7 where it was more severe due to the exynos chip. I had a spare S7 edge not used by me, so I installed whatsapp and restored the backup, and the same issue I described began. That phone ran cool without lag, now suffering the same fate as my A52s. I flashed the stock rom on the edge as well and it didn't seem to fix the issue either.

Sorry. I forgot to mention I had uninstalled whatsapp back in march, so the issue should be gone but it still persists.

You don't need to be so aggressive to me. I know what I am here for and I am trying to get help after trying to fix this by going to the service center where they claim false stuff, and whatever I posted earlier. Read what I posted, TikTok is not causing it neither is any app causing it.

Please read what I wrote above. Not tryying to start an argument here but sounds like you are trying to.
It does not matter if TikTok is installed or not. The same issue persists nevertheless and I already mentioned WhatsApp was not installed. Everything I mentioned above was tested by myself...
TikTok obviously is using a lot of battery because it has been on for a long time. Same thing, does not matter if it's installed the same heating and battery drain issue will occur in other apps. (Normal usage, not gaming or doing anything that stresses the phone)
What I am trying to gain here is advice to fix it, not asking for blaming on apps or useless advice because you never read my post.

This post is similar to what I am experiencing at the moment but for a different reason. Going to the service center isn't really an option anymore because they do not believe me and make up false reasons for this problem, and I am not a very confrontational person either.

I'm not a huge fan of these types of apps but one might point you in the right direction here - try and install something like AccuBattery and let it go for a few days. See what it says for battery usage.
It's been a while but I think there's an additional setting in the app (AccuBattery) that will enable the app to get more details, make sure you do that (was an ADB command if I recall).

Absolutely, I will install it and let it run for a few days then report the results back here.

Did you try enrolling to Whatsapp's beta program or sideload the latest beta from apkmirror and compare the battery drain between the two versions (Stable vs Beta)?
