battery issue in lollipop

Anyone having terrible battery? I'm at 55% with only 40 minutes screen on time. For some reason "Android OS" is at the top of my battery list. Any suggestion on how to fix this? I'd hate to go back to KK. At this rate I'd have to charge 4 times a day. I lost 4% writing this post...

After the upgrade to 5.0, on a full charge it says my estimated time left is 4 hours.
Not sure what's going on here.

I'm guessing it's the old "Miscellaneous" issue that plagued the Dev Preview, that Google was saying they fixed, only now it's called Android OS. It even uses the same icon.

Mine is dropping rather quickly too. 12% in 1 hour with minimal use.

Yeah its same (or worse) here. I came to look if somebody had posted something similar about it - or to know if I'm alone in this.
It is so bad that on USB charging it actually discharges if the screen is on! AC charging is alright, but as soon as I take it off charger, I can almost see the percentage dropping.
Project Volta they said. There will be battery improvements they said.

I loved the look and feel of 5.0 (Preview). I was even willing to give up all custom ROM tweaks and Xposed modules for it. But after a week I had to come back to KitKat because the battery on Lollipop was so bad I literally couldn't get through the day.
KitKat feels so 'agricultural' in comparison to 5.0, but it just works and my phone doesn't die in 6hrs.

Mine isn't too bad... Reporting 8 hours left with 55 minutes SoT only at 75%. I switched from my One M8 so I expected a drop in battery.
I'm going to let it settle in though. Liking the look and feel of lollipop too much to go back to KK. The weekend will be a good test for me.

I rooted and took out Google's bloatware.
6%, 4 hours SOT, Been using a lot of chrome, YouTube, and Chrome video playing, also did the removing of apps, got a feel for the system and functionality testing.... This thing went through a hellish 3.5 hours in my case.
Personally, I'm impressed.
Suggestion? Root and remove bloatware apps.
Also, Greenify apps.
I believe the only thing that isn't too like is the battery drop when sleeping. I haven't done any detective work on the wake locks just yet

This. My biggest sacrifice moving from KK was XPosed and the selection of awesome modules I was using.
I just finished restoring my nand backup of L Dev preview - atleast the battery is ok on that. Didn't notice a difference between it and final release anyway.

I am having battery drain issues also. Off the charger at 730 and down to 44% at 1130 with about 30 minutes of screen on time. I am rooted, so I wonder if modifying the boot image to root lollipop is doing something...

I removed Chrome, G+, GP Movies, GP Music, GP Games.. disabled Keep and Drive etc. I didn't use Greenify as I usually get better results with DS Battery Saver. Nothing I tried helped... back to Dev Preview for now..

I'm at 87% with 25 minutes and 30 seconds of SOT since 9am this morning.
Proportionally, that would put me at ~3 hours and 12 minutes of SOT.. usage has been fairly light, too.

We know not everyone is having problems. So posting about a Ok or above average battery life doesn't help us poor suffering souls much
Though it'd be awesome if someone who is going through the pain comes across a way to solve the issue.
For me the worst battery eaters are always:
- Android OS
- Google Services
- Android System
- Google Search
- Miscellaneous (sometimes, but its not the worst one)

Understandable, though there's no harm in having "normal" numbers for the sake of comparison as well.
I had issues with the Google Play Services keep-awake nonsense on KitKat, so naturally I'm keeping a close eye on what processes are draining my battery in L as well.

My battery is also suffering pretty badly. A week before I updated while I was on KK, the battery was horrible. 2 hours SOT from my usual 3. Idk what happened to Project Volta but... this is NOT looking good.

Yeah.. and as you can see from my list above - the worst ones are all Google. Btw read 'Google Services' above as 'Google Play Services'.

I did read in the code blue kernel thread the kernel dev mentioned that some root apps like Titanium Backup for example can cause the daemon su to lock the cpu up which causes high battery drain(Post #4913 http://forum.xda-developers.com/goo...ent/kernel-t2697951/post56634422#post56634422). I did use the beta titanium backup after I used cfautroot because the normal titanium backup wouldn't work. I wonder if that had any effect. Did any of you others with battery issues use titanium backup to restore anything?
I deleted Titanium backup and restarted my phone. I am going to evaluate after a full charge.

Anyone else experiencing poor battery?

I bought my Pixel in Nov 2016. Battery lasted on average about 1 day & 10-20 minutes based on my personal usage. In the last few weeks, it barely lasts 24 hours. I haven't added any new apps. My battery usage info doesn't show anything unusual or an app consuming a lot of battery. I downloaded GSam Battery Monitor but that doesn't give details on app usage unless you are rooted which I am not.
Have others also experienced poor battery although the phone is not even a year old?
Any ideas on what it can be? I haven't changed my usage either (I only monitor it on weekdays since that usage is basically the same each day).
Just an example here: took off charger 52 mins ago and it's already at 89%.

What software are you running? If you don't get the OTA for 8.0, I'd enroll in the Beta. This will prompt you to get the official release at this time. Once that's installed, I'd Factory Reset data and start from scratch.
Alternatively, you can uninstall apps one by one to see if there's an increase in performance/battery life. Also, maybe try wiping cache to see if that helps.

Yes mine went from 5-6 hours SOT to maybe 3 1/2 to 4. Horrible. I've flashed countless factory images. Never abkr to figure it out.

I wouldn't expect it's related to the age of the device necessarily. I only just got my Pixel a few weeks ago and it averages about 4 hours SOT over 24 hours with little left in the tank. It's got a small battery.

Mine is terrible on Oreo

You have to give the software about 2-3 days to learn your usage so that it can set everything for you, if you just installed Android Oreo, then, it's going to be at least a day or two before your battery corrects it self.

I have been on the Oreo dev preview, back to Nougat, now back on Oreo and the battery life just has gotten to be terrible. Factory wipes every time I load a new version on Android.
I get about 1.5 to 2 hrs SoT in a 12 hour period and it just about is dead. I have surrendered to the fact that I will just never had good battery life as long as I own an Android phone and I charge them any chance I get.

Personally I use Wakelock Detector on a rooted phone, but it may be possible to get information without root using ADB.
https://plus.google.com/+GeorgeTanner/posts/gT5f7XntmEu
The Wakelock Detector instructions for not having root are more thorough.

I am still on Android 7.1.2 running the latest update - NHG47Q (I think this is the latest). I have not tried the Oreo beta but would hope the battery life will improve since that is one of the new features.
I have heard that one should factory reset when going to a major update like 8.0. I just hate to reinstall everything (apps & settings) from scratch. (I am not rooted.)

Shouldn't have to do that... I've never bothered and it's not caused me any issues. I think people who suggest you do that are probably the same ones who suggest you wipe cache and dalvik cache all the time (burn).

The screen takes an awful lot of battery on this device.

My battery life was getting worse, and a factory reset a few days all fixed it.

The only issue with that is reinstalling all apps and settings.

Standby time is immensely better but lost an hour or so in sot

My battery drains really fast after I upgraded to Oreo 8.1. 30 minutes of Youtube used up 20% of my battery. It used to be only 10%.

I am,went from 5.5 on nougat to 4 on Oreo to 5 again on 8.1 dp1 and back to 4 on final.....sot of course. No change in usage

try getting rid of Back up to Google Drive took my SOT from 2hrs to 5 very odd

[OOS 5.1.8] Battery life got really bad somehow

As I've gotten my new oneplus 6, battery life was amazing. I got around 7-8 hours of sot (and average use) with one cycle.
Now I'm on 5.1.8 and with the same usage I get only around 3-4 hours sot. Only thing that I've changed over the weeks; I installed xposed. I don't know if this is the issue, cause I only ran like 3 modules with it (Greenify, Snaptools and NSFW Gboard)
Something else to say, my op6 is heating up more then it should be recently. Like I'm only using whatsapp and instagram, and suddenly it becomes uncomfortable warm.
In settings I also made all battery improvements, given in a thread here.
Can someone imagine what could be the problem? Or does someone have such an issue also? I uploaded some screens in attachments, maybe this is helpful.
Thank's!

Sometimes it can take a few days for a new update to settle down. If it keeps up, you might reflash. Also, check for rogue apps and wakelocks, which can flare back into life sometimes when you update. I have not noticed any real difference in battery life.

It hasnt made a difference imo for my device anyway. From changelog nothing should affect battery tbh. Maybe wakelocks or something plus running xposed with modules is never good from experience

Well I'm on 4G most of the day, I think this makes a difference because I only get such good results like 7 hrs sot when I'm on wifi. With Airplane Mode enabled I lose about 4% over night, I think this is normal or?

Noticed this as well with the update...
Even clean flashed

I have the same battery life as all the other part builds. Actually better since I just added ex kennel.
I stay on data, never WiFi since I'm on T-Mobile with unlimited and never get throttled. I loose about 2% overnight (about 7 hours) though I do keep my syncing under control. 1 email account is set for 3 hours, work is push, all under Google account is turned off since I only need calendar and contacts syncing when I make a new entry so I just manually turn sync on then back off. And I turn all background data off for everything other then what I need like messaging apps and email, Google app and that about it. Nothing to crazy but why let things sync constantly when there's nothing to sync?

For me, definitely thought 5.1.6 was the best for battery life.
Have you tried going into recovery and wiping cache? Worked for me.

6+ SOT on all 3 builds so far.

Battery Drain on Android Pie?

Hi All--
I've been on the Android P Beta for a while.
However, starting with the final beta that was released (and now on the final version of pie) I've been experiencing really quick battery drain.
Tried a total wipe and restore, and the same thing. My wife (also the pixel) isn't having those issues at all.
Thoughts?
(nothing shows up in the battery section)

Yes, I had great battery life. Then once Android Pie was released, jumped on the beta to get 9 sooner. Then got the upgrade from beta to final and battery life is horrible. I did not factory reset, I have battery saver on and it doesn'tseem to matter. If I leave on standby, no issues. If I use the phone, it can bleed as much as 10% per hour! Unacceptable. I may try factory resetting, but idk...

have you allocated sufficient time for app battery optimization?

I also have a pixel, Android 9.0/Pie (bought it brand new three days ago) and think battery is draining very (!) quick.
Yesterday I had roughly 2.5 SOT (with battery saver enabled) and this seems consistent with what I can expect typically. I did factory reset and have tried restricting "background activity" for my frequent apps - seems to make no difference. Obviously it had not time to do full battery optimization yet I guess, but I doubt it would mean a that big difference?
Saw a thread where someone mentioned it seems CPU-freq is high/inc. very rapidly when just tapping the screen (GPU-0%), and I can agree with that although I have not the prev. experience of what to expect.
My previous experience is with Xiaomi mi6/mi5 (lineage 15.1), similar usage would give 2x or 3x SOT (however with some other hw-issues.. ).

Flashed factory image without -w/"wipe". Will that do or should it be "full" factory reset to make sense?

Thank you for your information, I will stay on Oreo.

I don't think it would make a difference. The user data is on a different partition.
You could try flashing the image again, without Magisk or any other additions.

I had used up 50% with only 21 minutes screen on time.
I noticed the app Device Health Services, was constantly active in the background.

I had the same like the OP: everything was fine until the last beta came, and battery is draining faster, phone gets hot from even the smallest usage even in the prod release of android pie.
I was thinking it has something to do with being about 36 degrees (summer time....), but it is the same even in cooler temperature rooms. It's like if the phone is constantly doing something in the background, but only if I use it.

It has been a few days since I upgraded my Pixel 2. Battery life is noticably worse, maybe 20-30% more battery drain in a day than what I saw in Oreo.

I notice the issue as well. I did factory reset after update it's been a week. I was on beta and started noticing battery issues in the first beta and throughout. I decided to install Accubattery to track my battery usage and ended up with a result.
My phone states the battery is in good condition but this app says otherwise. I guess it's time to change the battery along with cracked screen!

i'm curious if my battery is shot as well... Seems like after I purchased my used Pixel.. the battery is not as lasting as I hoped for the smaller pixel phone... I may try one of those battery testing apps to see if it will tell me its current health..

I normally welcome up updates, but this update screwed up my battery life so bad. I mean everything was perfect until the update. Now the battery drains so fast I can watch the percentage count down like a timer and now when the battery gets anywhere from 15-40% the phone will just shut down.
I would like to go back to oreo, but it's such a pain in the ass having to back everything up and flash a ROM considering I haven't done that since before I bought the pixel

I have the same problem. I hope Google can fix it.

Wow, that is not normal. Stock android 9 with root and elemental kernel.... I go back to android 8.1.0 and wait for feature releases

I think I found an Draining App/Setting
I disable the RCS Service on my Phone. It can be found under Messages >> 3 dot Menu >> Settings >> broadcast News. Disable it.
And then Bluetooth and WiFi scan disable.

Same here, crazy idle drain after pie, only 50% deep sleep, tried factory reset and no luck

Try BetterBatteryStats. People in that thread spend their free time analyzing logs to tell you what's eating up all your battery life.

Question 7 pro battery drain

In last few days I noticed battery drain. And as well I think it started same time I noticed screen flickering when in battery settings. Video explaining attached. As you can see its fine until I get deeper into settings then "system operacyjny Android" starts flashing slightly and screen flickers and it's laggy. It stops and then starts again Anyone else has similar problem?

XDA allows 200+MB attachments?
It'd be easier to describe (in English?) the settings path you took.

I was surprised too sorry it's in battery settings and that's what's flashing "android os"

Hi mate, I do have the same problem with the battery settings view. But no solution so far.

Looks like a small glitch then. What app can you suggest to have a proper look into battery usage? Like idle etc with details. Something is draining my battery. I have accu battery now but I don't see any details there

I've rooted all android phone since I bought my pixel 7 pro a few days ago. Don't want to root again because of magisk hide etc. But there a a few things, like the battery section or the missing nfc quick tile, that makes me to want to flash a custom Rom. But so far I stay strong and keep the stock Rom.

I don't have that glitch... Rooted here.

I don't have that glitch, either

Perhaps a full device wipe is needed.
If I continually update and re-root my phone each month without the "wipe' parameter, I eventually run into some not-super-noticeable OS issues. But, of course, once that occurs I just make a Google Drive backup and re-image my phone with the same factory image. However, I just leave the wipe parameter in the flash-all batch file when I do this and any OS or root problems seem to be resolved after doing so.

You don't need to re-root with every release. Just use Pixel Flasher.

If I remember correctly, Pixel Flasher is re-rooting after full system images are flashed. Or perhaps it updates over the OTA method? Regardless, I have never used it as I have never needed to, haha =P. Re-rooting only takes me a a few seconds =)

Nope, it patches and flashes the image automatically itself.

So, it is re-rooting after the updated system image is flashed, haha =D.
Just for clarification, rooting a Pixel is done in the act of patching the stock init_boot.img and then flashing it. When the system is updated, the entire factory image is flashed, and thus, the previously patched init_boot.img is replaced with a stock, unpatched init_boot.img. At this point in time, the phone is no longer rooted. But that is why users like us re-root our phones afterwards =). The Pixel Flasher is just incorporating that re-rooting process into its convenient, ease-of-use application experience - which is a very good thing to provide an option for.
Every day is a new day to learn something different =).

battery drain on a smartphone can be caused by various factors, including:
Screen brightness: A bright screen can drain the battery quickly. Try reducing the brightness of your screen to conserve battery life.
Background apps: Apps running in the background can consume a lot of power. Make sure to close all unnecessary apps when you're not using them.
Wi-Fi, Bluetooth, and GPS: If these features are left on when not needed, they can drain your battery. Try turning them off when you're not using them.

The thing is that that drain started on Friday I think. Didn't install any new apps etc. I have around 30% phone iddle - is that normal?

What do you mean 30% idle?

Like that

Ehhh when idle apps are still running in the background checking for stuff etc... It'd be better if you used some other battery analyzer like GSAM for more details.

Ok so looks it's back to previous battery performance after yesterday's update. Definitely flickering problem is fixed and that's my today's battery result. And the phone idle seems gone down from 25-30 to 15%

I have the same issue since the last update from I think Monday evening.
Since then my battery drains a lot faster then before. I have a loss of 30% during a night without doing anything within these 7 hours. Before the update it had around 6-8% less in the morning. And it drains a lot fast during the day too. I have 100% after charge in the morning, go to work and when I come back it is down to ~30%. Last week it was on ~60% or more when I came home.
No new apps, nothing changed except the update.
This is really annoying me!
Don't want to wipe the hole phone as I don't use any Cloud on my ohones and would have to backup via MyPhoneExplorer and set up all by hand again.
Or is there any backup solution to backup everything on a phone all at once without root?
Oh and my Idle has around 30% battery usage, before the update it was on maybe 10% during a day.

I've been through this. For no reason, it's an insane battery drain. I ended up wiping and reflashing the newest firmware, staying on Stock Kernel and restoring my Swift backup - user apps/data only - and only logged into the apps I actually use and it got better. Not perfect, but better. After I week I reflashed the Kira Kernel and it's been back to pretty stellar again, like you said, only dropping a few percentage points at night
