Poor Battery Life on Android P - Google Pixel 2 XL Questions & Answers

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!

I had a similar experience. Battery life was awful after Pie update. Factory reset and it's back to normal.

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

[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

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.

Battery drains after updating to Marshmallow.

Ny battery's been draining fast as hell ever since updating to Marshmallow, and the top three consumers are: Android System, System (logd), Kernel. They have never bothered me before. They use 60% of my battery consuming. Checking again now, the "logd" changed to "dboxed_process0" and "logd" no longer exists. My battery doesn't even last 2 hours with WiFi when back then it used to last 7 hours woth WiFi. What the hell can I do?
I am seeing a faster battery drain, too. Greenify doesn't even seem to help.
Factory reset is your first thing to do after such a big update, everything else you try is a waste of time until you do this.

Oneplus 3 Nougat Battery Life

Hi all,
Now, I've never gotten great battery life (combination of screen on time and idle) with any phone. I don't use them all that much apart from bursts and my OnePlus 3 would get me 3 hours SoT tops within 24 hours before I need to charge again.
However since Nougat I'm struggling to get even 1 hour SoT.
I'm using Bluetooth, NFC, both SIMS and nothing else untoward. This is the same as pre-Nougat.
Anyone else seen their battery life die since the update
Try to use 1 sim. I have 3:30 sot for both sims. And 7 for 1 sim.

Batter life is great i suggest you do a clean install wipe everything on your phone after making a backup on your phone ofcourse and start again. I use 2 sims and i have an average of 5:30 to 6 hours sot

Hey Konvict
Can you answer these questions then please?
How long a period of time is that 5-6 hours of SoT over? 24 hours of standby?
What radios and apps do you have running that might eat battery?

I would say about 24 hours....i normally charge my phone at the end of the day when i have about 40-55 percent battery left but even then i usually have goften 2:30- 3 hrs screen on time depending on the day. I will attach a screenshot of my battery today and maybe u can take a look at it.
Actually today this nougat looks very good.
I'm getting awesome batter life.
First two pics from OOS 4.0
Last two pics from OOS 4.0.1
You both seem to be using both WiFi and multiple SIMs - strange then.
I can't use GSAM as I don't have root and Nougat stops the app by app recording of battery use for third parties, otherwise I could see what was happening.
I do have a number of email accounts, and messenger apps, but these sit dormant most of the day (i have no friends obviously lol)
Hmm, maybe a wipe IS needed.
You guys got a great battery life, I got 2:30 in my good days, never above it!
However, someone told me to switch Doze off from developer options, I just did that and I'm currently charging my device, will see if it do any good by the end of today "fingers crossed"
PS. I'm using Freedom OS 2.0 with clean install + using Bluetooth and 2 SIM (one for calls and the other for data)
I'm also noticing a big drop in battery life after switching from marshmallow to nougat on my OP3T. Cleared cache & did factory reset, as I always do. All apps and settings the same, and usage the same. Drain seems to be extreme, not sure what's going on. The battery life was AMAZING on marshmallow... kind of regretting switching now

Go back to the previous versions of Facebook and Messenger. These two have been draining battery like hell for sometime now.

Are you happy with Android 10 on this phone?

I've been running Android 10 since release and I have to say it has been the poorest experience yet since the phone first came out. It is too aggressive closing background processes. I can't have a podcast play to completion without it just closing and even forgetting where I left off. The leg is horrible and my battery life has gotten worse since pie.
Am I alone or is anyone else having a similar experience?

I like 10...No issues other then bluetooth connectivity occasionally acts up when connecting to my vehicle and running Pandora. I never cared for 9 and went back to 8.1 on my PH-1 until a stable version of 10 is available.

Other than Google headed toward completely locking down recovery, I've been happy with it. Stock, rooted, EX kernel. Not experiencing any memory or lag issues at all.
Hello,
I have the device since ~ two months. I don't have any special complaint...
Battery is rather good for the moment. September version was quite buggy..!
I think the october release improved the experience a lot...
Actually stock October image + Root + EX Kernel.
Cheers...
Sébastien.
I only have two issues, and both aren't deal breakers, but they are concerning a bit. The first is random reboots like once a week. It doesn't matter what I'm doing as it just decides to reboot. The other is a bit more concerning as it happened twice since 10 was officially released. Again it doesn't matter what I'm doing, and the screen will go black, and become unresponsive. I have to force a manual reboot, and when it tried to boot the splash screen flashes several times, and then it boots into recovery with a message "Could not load Android OS. You can try again, or do a factory resest.". I selected "Try Again", and it booted normally, but I don't like risking that. Other than those two issue it's been super smooth, and very snappy. I have no complaints about performance at all when it's working normally.
Thank you for the responses. I'll try to wipe and reinstall to see if that helps.

Glad you've mentioned the podcast problem. Same here. Either stops randomly and when going back in then it's back to the beginning. Are you using Google Podcast app?
Yes, that app has been the most frustrating. Although, iheart has given me the same problem. Nothing like listening to a 4 hour episode of Hardcore History and then losing where I was just for checking how bad I'm doing in fantasy football. Double kick in the nuts...

I liked the Android 10. Don't have problem with apps closing or RAM issues. My problem is with the battery draining. Already done a factory reset after the OTA, but the battery life is getting worse every day. Have no social networks besides WhatsApp, using a few data because I live in small town that every place that I go have wi-fi. Using pie, have 36/38 hours with 4.5/5 hours os screen. With Android 10 now have 30 hours at best with 5/5.5 SOT. Battery is draining like 2% per hour, and it really bothers me. Also, full stock here. Probably will back to Pie soon.
november update seems to have made some improvements with battery life.

Not for me no. I got the phone back in June.
The battery life on P3XL is garbage. The P3XL is 2 months old. I have a 2 year P2XL with the exact same setup and the exact same apps. The battery life on P2XL is at least 50% better, even though it has been used for 2 years.
With identical usage, the P3XL drains battery twice as fast as P2XL. I've compared multiple scenarios with identical usage on both phones.
So no amount of Vodoo magic will fix the battery in P3XL. It's just terrible. My hypothesis is the battery temperature. I have an app that measures battery temperature and the P3XL seems to have a similar problem as P1XL - it runs WARM.
The P2XL, however runs much cooler in temperature So for ex, browsing Chrome and checking email, the P3XL might be at 35-37 Celsius, but the P2XL will be at less than 25 Celsius in exact same conditions.
Charging the P3XL also make it reach sometimes 40 Celsius, playing game over 45 Celsius. The P2XL almost never goes over 30 Celsius even on heavy load.
The battery in P3XL also drains very quickly with screen usage. I think the phone suffers from poor optimization, bad thermals, overheating and a battery hungry screen.
I'm always stressed out when being out without a charger for the P3XL. With the P2XL - it's never been a problem. I only charge it after 2 days.
to me, Android 10 has been the worst update on the Pixel 3 XL.

This is exactly how I feel. Sad Google decided to lock-down recovery, but it was just a matter of time. Wouldn't be surprised if this is just another step towards eventually removing us from obtaining root. (hope not)
But other than that, I love Android 10.. I love dark mode, bluetooth has been stable for me and stock rom with EX kernel has been great. But that's also been the combo I've had on my phone for years dating back to the Nexus 6P.
Just leaving this here
And I just want a customisable navbar.
Is it so hard Google?
