Bad battery life after March OTA - Google Pixel 2 XL Questions & Answers

Hello everyone, I was getting EXCELLENT battery life on my phone consistenly ( 7 hours of SOT over 30 hours ), until I flashed the march OTA.
Do you think factory resetting the phone may fix the problem ? or maybe something else ?
My phone is rooted with stock recovery.
Thanks

Only one way to find out my friend. Many folks have done that very thing since 9.0 hit last August to rectify poor battery life. Personally, I do that very thing every 3-4 months just to keep things cleaned out. My P2XL is 18 months old and I still average the same SOT as I did when I got it :good:

I tried a factory reset too due to low battery life. At december path I was near the 8hours.
Now it's more like 6h-6h30. It still good but far away.
Today I desactive in "options for developers" and 'tracking system" both slides. Battery life seems better. I will see later.

[Q] Huge Drop in Battery Life after 2.17 Update

Hi all,
My battery life on the One X has been great before the 2.17 update. Better than the average being reported on this forum.
After 2.17 it plummeted to 14 hours or so with barely 2 hours of screen time.
Nothing was changed after the update on my end. Same apps, etc. All on stock.
What are my options? Will a hard reset solve it?
Thanks.
Update
The factory reset did the trick. Battery is back functioning properly and I did get extra juice out of the 2.17 update.
If you do find a weird drop in battery life and the ONLY change is that you updated the firmware, a hard reset may solve it like it did for me.

You should go thru a couple of charging cycles before complaining about battery time.. everytime you flash a new rom or update the phone the battery has to calibrate ( as far as i know ), and that takes about 2 - 4 recharge cycles..
in case you already done that, then check you sync settings, brightness if its too high, or low.. Maybe you are used to be on wifi instead of 3g ?
It has gone through over 10 full charge cycles.
Sync is off. Brightness minimum.
Wifi and 3G usage patterns are similar.
Just noticed that Phone Idle is consuming a lot more.
Maybe it's the new radio which is affecting your signal, try flashing an older radio. My battery life is better on the new firmware.

i first of all found the battery life had dropped, i ended up resetting the phone and it got much better, i think some old app was getting lodged in the memory and preventing deep sleep.
i ran it for about 2 weeks before i decided to wipe.
@nikzDHD
I suspect it could be that. My provider does not provide that strong a connectivity. But that is something I can't change for the next year or so.
@audiobookman
I decided to wipe it today. Also waited about 2-3 weeks before deciding enough is enough.
--
I did a HTC Battery test and found that my battery was in good condition and performed way better than their baseline. So, I went on to wipe the phone clean and started from scratch.
It was not a painful process actually. Most of my stuff are on the cloud (Google/Dropbox/Skydrive) and the only things I had to back up was the list of apps I had and some settings from apps like Tasker and Minimalist Text. I got everything back up and running within an hour + (reinstalling 60+ apps and getting them setup the way they were takes time).
So far, battery seems a lot better and back to the former period but, it is too early to tell. I'll give it a week of use and a fair amount of full charge cycles before commenting.
Will update this thread then.
If anyone has other ideas please sound out. Thanks a lot!

I do a factory reset after every OTA because of the reasons you mention of this thread. After it battery life seems to get better or at least not worse as on previous firmware version. I hate doing that but it seems the only way

keep calm and factory reset. That should fix the stability and battery life.

No better no worse, my battery life has always been great. Example today, unplugged at 7 am , no recharges during the day and it's at 55%.
I used the phone , surfed and checked my texts and email all day

You are not alone. I used to be able to go a couple of days on a single charge. Now I'm struggling to make it 12 hours on a single charge.
I was getting almost 2 days when I first started using the note4. After a few months passed I noticed battery life dropping pretty fast throughout the day. Factory resets helped a little, but not much. Lollipop upgrade plus factory reset has seemed to help. I get through a full day now with light browsing/gps(maps)/gaming and fair amount of spotify streaming. Nothing close to what I was getting fresh out of the box.
I am experiencing similar battery issues. Used to charge my phone once every two days. Now, I carry my charger attached to my hip like a feeble iPhone hipster.
I'm also having issues!
I also have seen a large decrease in my battery life since updating to Lollipop. I tried factory resetting twice and nothing seems to help. I was getting 8-9 hours of screen on time on Android 4.4.4 but now I'm somewhere between 4.5-5.5.
Also my note 4 will occasionally get really hot after just normal web browsing. I'm very disappointed in the update. However, performance seems to be a little better....but it wasn't ever really an issue.
I just read an article on gsmarena about the international version of the Samsung galaxy note 4 receiving a firmware update.....hopefully that fixes the problems we're having. We just have to wait for Verizon to send out the update. (Which will probably take a couple of weeks to months).
One thing to keep in mind is that we (those who are having these issues) need to make sure that we contact Verizon in order to make sure that they acknowledge the problem and send out a fix ASAP.
I'm having the same issues since the update...battery sucks. What's the easiest way to inform verizon?
Passpoint Wi-Fi
Noticed that there is a "new" Passpoint Wi-Fi feature that will automatically connect to certified access points.
This is ON by default after the Lollipop update. (Settings >> Wi-Fi >> Advanced)
I just turned it off to see if battery life improves. Never been a fan of automatic Wi-Fi connection features.
Checking on the Lock Screen Weather/Location Update next.
My Note 4 has the battery drain issue now after updating last night to Lollipop but am giving a couple days to see if any improvement. I did do a battery pull after all the updates (system and apps) and it did seem to help.
My Note originally for a couple of days had the battery drain issue. However, after uninstalling the Google Fit app then a reboot the battery life has been great.
Maybe try a battery pull for 20 seconds as well.

I think the easiest way to contact Verizon is just by talking with the technical support. Good representatives are hit or miss but Verizon's are generally good.
If you contact them just explain the issue that you are having and they should be putting it on record saying that multiple people are calling in concerning a battery problem. They may have even figured out the culprit (s) and/or found a fIx.
I'm going to be calling today.

Horrible Battery Life on Nougat

So Just to announce where I am coming from, I am a Sony fan for the past 4 years, Had the Z2 and was totally blown away by the battery life it offered. Then I got the Z5P and even though the battery performance was nowhere near the Z2 I still got through an entire day with it without issues so I was happy.
Then came the Nougat update and all hell broke loose. I am literally getting just 6 hrs of battery life since the update. And even when it is idle it still drains battery like atleast 2 percent every hour.
Also the charging is very slow. I have a quick charger that used to take the battery life from 0 to 20 in atleast 10 - 15 mins. But now it actually drains the battery if I am using the phone while charging. And yes I have switched off the battery optimization option.
Any help will be appreciated even if it is just a confirmation that I am not the only one having this issue, which will at least let me know that it is not just my phone.
There must be some process with corrupted data after de update which is constantly executing something. I recommend you to do a full wipe, factory reset

Oh did not know this could happen. Will definitely try doing a full wipe and see how things go! Thanks a lot!
I never fully trust OTA updates, because it keeps all the applications data and some special case of your current configuration maybe is not "converted" to the new version and causes the programs to behave weird. Have you looked at the battery usage? Maybe you find the process which a huge % of battery eaten, and just wiping that app data is enough

Thanks for the reply! Yeah I looked at the battery usage stats and no specific app is draining more than 2 percent of the battery over a charge. The only things that have taken most out of the battery are 1. The Screen On Time which is to expected and 2. The Idle Phone which takes around 15% consistently in every charge.

after updating to .372 , i learned from internet that this build has battery draining issues. ( i never faced any )
after updating to .376. , the phone is as steady stable as my other xperias (btw z5p is my 6th xperia )
now there is however a catch.
1. if you updated on OTA , this means the update of 1.2gb via ota only replaced certain files from .305 to make it .372 build (android 6 to 7) --- such OTA updates USUALLY ends up having problems (in general) with battery draining issues. Such problems i personally faced during updating from honeycomb to ics. - in short whenever update is available; always install FRESH
2. if your bootloader is locked then use xperia companion to install fresh after wiping all data. (makebackups)
3. if your phone is not rooted then try disabling all un necessary apps under Apps section.
----
Trivia
You cannot compare Z5p with predecessors like Z3/Z2/Z1 and Z since
1. they were always smaller in screen size / resolution and were not 4k
2. They stops at Android 5 / 6 as their last builds and battery life was awesome w.r.t consumption

however some of friends on XDA agrees that .305 (android 6.0.1) (came out dec2016) is the BEST build ever for z5p. addressed all battery issues and it was the final build for z5p on android 6.0.1
even i am thinking to degrade my phone due to ram consumption of N is very high!
this is why xzp has 4gb ram!
I need to know. If I updated my phone to .376 and it's having this lack of battery life, DO I HAVE TO SELL IT OR DISPOSE OF IT BECAUSE IT'S LITERALLY A LOST CAUSE NOW? (P.S. I immediately did a factory reset after the Nougat install completed.)
Because apparently if you updated to this build, then returned to the last Marshmallow build, THE PROBLEM IS NOT FIXED, and reloading nougat will only make things worse. And if you updated to .378, it not only does this not get fixed, it breaks your headphone jack to boot.
Please help. I am freaking out about this battery life. I lost 60 PERCENT IN 6 HOURS OF BASICALLY PODCASTS. ?

Well, after all my trials I flashed MM back and everything is back to normal. The issue is with 7 so not sure what happened to your handset
EDIT: Re-upgraded once again= battery 8 hour life. Go into About Phone, Status and disable battery optimization. The handset reboots and incredibly this morning it was like the old days .

Maybe I'll try that. The best I was able to do was 21 hours with one bar LTE, 6 hour's sleep, and 3h40m screen on time with several hour's worth of Pocket Casts.
i confirm that on build .33 i lost my battery even on stamina mode one percent every 10 minuets over using wifi , it just keeps the battery when device is screen off -_- its horrible i didnt have this kind of problem with .253 and im wondering revert back to MM

Battery drain & bootloop when battery is low (Nougat | Stock)

Hi guys, I'm needing help with identifying issues I have recently after nougat update (Stock - Australian variant by the way)
1 - The battery life is getting as suck as SOT of 3 hrs or extra 30 mins at best (it was 4 hrs 20 mins + when I first got it late 2016)
2 - When the battery is low (below 20%) it sometimes enter bootloops for 3-5 loops.
I tried clearing cache in recovery / factory reset - not sure if it's nougat issue or the battery is already wear-downed in this case which would've been ridiculous for HTC standard as it usually happens only after 2 years or something.
By the way, I've attached the recent day of drainage and wakelocks etc.
any helps would be appreciated

I'm able to get rid of the bootloop by installing custom kernel (ElementalX, to be specific). So, it's totally software-based issue (dang it HTC!). However, the battery life isn't getting significantly better just yet as I'm still on stupid stock waiting for the warranty to be expired in the next 10 days and from there; I will just flash some better-optimized ROMs! Pretty sure result will come through for a much more capable battery life according to 3000mah!:fingers-crossed:

Poor Battery Life on Android P

Ever since upgrading to Android P (OTA) 3 days ago I've noticed the battery life is really poor. On Oreo I used to see only 1-2% drain overnight. Now I go to bed with full charge and wake up with only 60% left. The battery drains a lot faster when I'm using it as well.
I used to be able to get 6-7 hours SOT easily. Now I'm not even sure if I could squeeze 4 hours before the battery is flat.
Is anybody else seeing this? Or is this normal considering Android P just got installed and it needs time to "optimize stuff"? But then again, with Oreo I got awesome battery life from day 1.
Weird, I've gotten better battery life..
Better battery here
Interesting. I'll let it run a few more days and see if there's any improvement. Otherwise I'm going back to Oreo.

Give it some time, once adapative battery figures out your usage and adjusts accordingly, you should see better battery life

Try to factory reset ur device this may help
Thanks guys. I'll wait a few more days. If it doesn't improve will try a factory reset
I'm getting better battery life with Pie
Pixel 1 XL could last a long time. Pixel 2 XL was worse and the worst with Android P unfortunately. I upgraded from Beta, decided to factory reset since there was a bug with Wear OS eating the battery. Got a little better. Got some more little better disabling adaptive battery. I think Doze is still in Android P.
Anyway, it's still not that good. But decent.
I am having the same issue.
when I reboot the phone, the battery seems ok.
But when I start using the phone and open several apps, the battery starts draining quickly.
I installed magisk root, should I do a factory reset and not installing magisk?
I went from a day and 17 hours to 16 hours. This is definiately a piss-poor "improvement to battery life."

I'm not sure how much help adaptive battery is going to help. It's meant to limit background battery usage of infrequently used misbehaving apps. If that's not happening adaptive battery won't do much.

My battery life has been terrible. Today I unplugged at 93%. I've been off the charger for 9 hours with 4 hours screen on time. I'm at 23%. With Oreo that kind of usage would have me at about 40%.
I'd rather not have the hassle of having to do a factory reset but I might not have much choice.
It hasn't got any better since I reported the issue.
I think I'm going to flash Oreo instead of trying a factory reset as I doubt it would solve the problem. Maybe someone else could try and let us know.
I'll report back after flashing Oreo. Very disappointed. I thought this was the first phone I didn't need to tinker with all these stuff on. I was really happy with it until this issue came up.
So a few days ago I flashed Oreo only to have it tell me it couldn't find any of my backups on Google Drive during the initial setup. Of course, the backups were done when I was on Pie.
So I had to upgrade to Pie then factory reset. This time it found my backups.
Yesterday I managed to get 5 hours SOT with about 40% battery left. Life is all good now

looks like i'm going to have to do the same. It doesnt make sense how some people are getting better battery and other worse. Are there some of us running apps not 9.0 compatible? might be worth uninstalling everything and adding them back day by day. it'll take a long time though!

same here, slightly better
It appears I jumped the gun. The problem came back yesterday.
The phone loses about 4-5% battery per hour even on standby. I have no idea what's going on; I haven't installed any new apps and usage pattern hasn't changed either.
One very interesting fact I have discovered is that the issue appears to happen only when I'm on Wifi. When I'm mobile data, all is good. So the phone seems to be doing some funky stuff when it's on Wifi lol.
Oh well, I guess I will try to install BBS and see if I could find the culprit.

That is entirely possible. I guess we have apps that have not been written/optimized for Pie? That would explain why some people are not seeing the issue and some unfortunate ones like us are.
I factory-resetted the phone, the issue is still there. I don't have any strange app. It seems that it's just the system that is consuming the battery.
That's very strange I've had the complete opposite, battery life has improved, if reset didn't fix it monitor your apps for unusual battery usage and limit the background activity of battery consuming apps
