[Nexus 6P Q&A, Help & Troubleshooting] tropical cactus:
The best battery life will always be on the Android version with which the phone came out of the factory. It was fully optimized then. I never gave the phone a chance on mm since I only bought it last year and I updated straight away. However, I tried the last mm build before flashing Oreo. It was definitely better than now. But as someone said, you win some, you lose some.

I think it was the time to let go of my beloved Nexus 6P, however after I sold it I found out Google was willing to replace the PROVEN defective units with Pixels. since they don't have any 6P in stock anymore.

The phone was gorgeous and served me well, too bad it was plagued by these battery issues..

So now I'm left with no phone and with a big dilemma: what phone shall I get, the overpriced Pixel, the "i dunno when and if i'm gonna get updates" Samsung, Iphone is out of the question.

Hmmm decisions decisions... :) Will see.
[Nexus 6P Q&A, Help & Troubleshooting] wizardwiz:
I truly can't get it.

Most of us has the nexus 6p for about 14-18 months. each! and every phone I ever had, had a battery degradation after such period. Iphone have such degradation as well.

Most manufacturers never give any warranty above a single year.

Since I think the device itself is still great I will replace my battery if and when it's time.

Right now, 14 months of use, Accubattery say my health is 95-96%

If you like your 6P replace the battery and that's it.

Otherwise, pay of a much expensive device , maybe with a better battery.

I do agree that there has been a change with Oreo. Idle is amazing , while some apps do draw more juice.

Already been said. You win some you lose some :)
[Nexus 6P Q&A, Help & Troubleshooting] psychomaniac82:
Battery life is definitively better with O. Especially when screen is off. With nougat, sort of same configuration, I lost about 8 to 10% over night (about 8 hours). So I mostly used airplane mode. With Oreo i lose about 2% over night with everything on (data, WiFi, location & location history,etc.) except Bluetooth but that doesn't change much.

Sometimes Chrome went crazy and drained hard. So had to clear cache and data from chrome. Also Instagram and some other apps had to much background stuff going on, so I had to shut those background activities down from battery management. One of the best improvements of Oreo in my opinion.

And best of all, Oreo is a bit faster in loading apps!
[Nexus 6P Q&A, Help & Troubleshooting] rainfactor:
You are absolutely right, however there seems to be a mixed bag. There are people whose phones were affected by the inexplicable high battery drain and some that experienced a somewhat higher drain than the usual (not by much).

I was in the first category :) . I understand a 14 months old or more phone cannot hold the same charge as if it was brand new but mine was really bad. I guess it was just a coincidence that started right after I installed Oreo. It turned out, in my case, that even loading any other 7.1.2 ROMs didn't help.

I have looked at changing the battery but I decided not to pursue that avenue because:

1. It is still not clear what caused the problem to begin with, yes it seems that the battery dies faster but is it the battery or something else that causes it?

2.I did not find a reliable source for a potential replacement. There are only OEM replacements that did not inspire much confidence :)
[Nexus 6P Q&A, Help & Troubleshooting] wizardwiz:
I am aware of the fact that some people did have a problem with their battery.

The cause? overheating, the type of use, overcharging.. and naturally malfunctioning batteries.

Its a mix of all of the above.

I would expect Huawei to step up and take care of it's costumers and replace them batteries.

As for the oreo OS, a new one and I guess it will take another version or two to iron out all the bugs of version 8.0

As of now, idle battery is great , while SOT isn't as great.
[Nexus 6P Q&A, Help & Troubleshooting] rezzzho:
Like everyone here, I had exactly the same issues right after installing Oreo. The battery was draining very fast and I was sure that it was due to the Oreo update. So I remember how great my battery was in March and decided to go back to version 7.1.1 from 5th March. Now everything is back like it was. My battery is great again and I wont update my phone anymore. In my opinion this is just a marketing idea to make people buy a new phone.
[Nexus 6P Q&A, Help & Troubleshooting] rrohanjs:
i agree the standby time is much much better than nougat, do you also have google now on ?

also how did you shut the background services ?
[Nexus 6P Q&A, Help & Troubleshooting] psychomaniac82:
Yes, I also use Google now. You can shut down background processes per app, via settings, battery, click on an app (top most app, is using most battery), on the bottom of the page you see a switch, when it's off,Oreo limits it's background processes.
[Nexus 6P Q&A, Help & Troubleshooting] evrk:
Both my SoT and standby times increased a lot with Oreo. I found battery life to be the most consistent out of all Android versions. Keep in mind I disabled background activity for all the apps I could including Play Services and System. I'm completely stock and clean flashed Oreo. I'm quite impressed with Oreo.
[Nexus 6P Q&A, Help & Troubleshooting] rrohanjs:
can you post few screenshots for a days usage ?

also does disabling the activities hamper notifications in any way ? (also how to do it lol ?)
[Nexus 6P Q&A, Help & Troubleshooting] wizardwiz:
Do you use stock Oreo or anything out of the ordinary? Rooted? how about boot.img? any custom kernel? TWRP?
[Nexus 6P Q&A, Help & Troubleshooting] Zapperdk:
I have been checking this thread for solutions since I was also having a warm battery eating phone after installing Oreo. However, no of the given advice really worked for me.

Then this morning there was an update for 'Carrier Services' in Google Play Store. After updating to version 5.0.169183594 of Carrier Services (dated 19 September) everything seems to have returned to normal.

My phone is no longer eating the battery for no apparent reason and is also down to normal temperature when idle.

I hope this small update will solve the problems for most of you too.

[Nexus 6P Q&A, Help & Troubleshooting] NXJeff:
Did you try to roll back naugat and see if the battery life any better? Might be your battery run into the infamous battery issue.

I am having better battery life, performance as well on oreo compared to nougat.
[Nexus 6P Q&A, Help & Troubleshooting] v12xke:
Your battery is likely degraded. Install and run Accubattery to get an estimate of the remaining capacity as compared with the original battery (3,450 mAh). After a few charging sessions check the battery health tab and look for "estimated capacity" as a percentage of the original battery.
[Nexus 6P Q&A, Help & Troubleshooting] Mdknight:
I actually just RMA'd mine, too. (It was still under it's original manufacturer's warranty time.) I bought it off of Swappa and they accepted a screenshot of the purchase page as proof of purchase. You can message their customer service with the serial number to check the warranty time left. Whole process took less than a week.

After updating to Oreo, from Marshmallow (I missed Nougat), I have not noticed any negative effects on battery. This after about a month since update. Knock wood... ;)
[Nexus 6P Q&A, Help & Troubleshooting] daviderickson:
I went from Marshmallow to Oreo (clean install) and saw at least a 50% drop in battery capacity. Also I see the system turning off at as high as 20%, meaning I have even less battery. I did a test, just to see, and went into recovery after Android turned itself off at 20%, and on full brightness the phone stayed alive for way over an hour.. so something seems really wrong internally.

Hi, im running Stock Oreo october security patch.

Since nougat my battery dropped from 5h SoT to 3 and never reverted back to that amount. Well, this changed today by luck.

What I did was:

- I entered in settings and looked in developer options in the running process and closed a lot of them that were running and eating power (ES explorer, chrome, icon packs, etc.)

- Then I checked in memory section and saw what applications had the most impact and I stopped them (there were a lot useless). Also I deleted some of them.

- lastly I disabled printers on the conected devices section ( I dont use them and if I were I can just re enable them.) and after this I shutted download the phone and cleaned the cache and restarted. Voil
[Nexus 6P Q&A, Help & Troubleshooting] v12xke:
Yes, you have a badly degraded battery. Nothing to do with Oreo. Time for a replacement battery.

Drain after October patch

Hi guys, i have updated my phone to oreo since the very beggining. In the first days, i had noticed some battery drain, but after some days, got back to normal.

But, unfortunatelly, after last october patch, i started facing some serious issues. The phone has to be pluged all the time in charger. In drains pretty fast. Something to 2-4% in ten minutes, even with the phone in standby. I was used to spent 20% with waze in my job path, now it pumped to 40%.

I already tried all the recipes suggested, wipe cache, clear app caches, none seems to work.

I read somebody suggesting something about PIP. Made these last suggestions, disabling pip, enabling gpu rendering, disabling nfc, printer. Also, unistalled Dailymotion app, which for sure was invoking PIP.

I will report later.

It's been great for me. Some of the best screen off idle I've ever had .1% an hour over night and usually average in the in the low .2%. screen on time has stayed about the same around 18 - 20% drain screen on. I charge to only 80% with charge limit and get right around 4 hours sot with 80% charge.
[Nexus 6P Q&A, Help & Troubleshooting] v12xke:
How about the part about testing your battery's capacity? You can't tweak away the symptoms of a badly degraded battery. Run Accubattery for several full charges and then report back with your battery capacity found under the health tab.

[Nexus 6P Q&A, Help & Troubleshooting] Urbn_Nrd:
You need a new battery

Try changing the battery on your phone. I ordered an "OEM" batter off eBay (of course it's probably a knockoff), but it significantly increased my battery life. I also, performed a fresh install of Oreo and my battery life is far better then when I first purchased it. Give that a shot and see how battery performance improves for your phone.
[Nexus 6P Q&A, Help & Troubleshooting] v12xke:
Sure. Like everyone else says.... time for a new battery. It has *zero* to do with you upgrading to the latest OS. If you doubt this, run Accubattery and get an estimate of the remaining capacity in your battery.

1 Week w/ a New Battery & Loving the 6P Again

My 2-year old 6P had battery issues (shutting off at 30%, draining super quickly, phone seemed warm). Tried getting Google & Huawei to replace the battery, but the best I could get was a $20 credit on Project Fi.

Tried cache reset, full reset, update to Oreo, and nothing made a difference. AccuBattery reported a capacity of about 1300mAh (as compared to the design capacity of 3450mAh).

Having zero experience opening up a phone, I bit the bullet and spent $100 to get the battery replaced at uBreakiFix. (a place nearby got good reviews, so I took a little bit of a risk)

It's been one week and I feel like my phone is brand new again. I wish I would have done it sooner... AccuBattery reports an estimated capacity of 3,469mAh and I no longer have to charge my phone multiple times during the day.

Best of luck...

I had same issue with battery, I even was going to buy a new phone. But I ordered a new battery and replaced old one. One month use, so far so good.
[Nexus 6P Q&A, Help & Troubleshooting] Ohanabuoy:
I was having my Nexus 6P die around 30% battery power. The phone was out of warranty but Huawei replaced the battery for $151 including shipping. The good thing is it was fully covered under American Express's Extended Warranty. If you bought your phone with an American Express card they double the manufacture's warranty. I had to live without my phone for exactly a week but it was worth it. Battery life is excellent. After a 16 hour day I have about 18% battery left. BTW, I am running Oreo.
[Nexus 6P Q&A, Help & Troubleshooting] R4DK0:
I get about 10 days on wifi only with minimal usage on Oreo. Currently on XZ Premium with an amazing battery life and performance, on Oreo aswell.
[Nexus 6P Q&A, Help & Troubleshooting] jerm1027:
I've noticed a massive battery train when using Bluetooth Audio devices (car stereo, motorcycle comm, portable speaker). I suspect there is a bug as prior to the update, my battery life was fine. I could Pandora all work day and commute to my evening class, and get home home with ~20% battery life (basically a 14 hour day with heavy background usage and about an hour's worth of BT audio). Now I seem to lose 1% of battery per *minute* on Bluetooth. My phone will basically be dead at the end of the day minimal use (none during the work day, 30min YT during lunch break, and same hour of BT audio).

Anyone else having this issue? Will update with screenshots later.
[Nexus 6P Q&A, Help & Troubleshooting] v12xke:
Not here. Stock ROM, rooted, EX Kernel. I use BT audio extensively every day in both cars plus a BT speaker on the patio a couple of hours a day and do not see the drain you are describing. If you have not done so already, test your battery with Accubattery to confirm you have good capacity left (say, over 90%) and if so, back up your device and do a factory reset. I'm not having the issues you are, but plan on doing this when 8.1 final rolls out. Just like I did with 8.0. Nobody wants to hear their battery has taken a dump, or that they need to wipe their phone, but this resolves the issue 99% of the time. All this being said, the November update included a lot of functionality improvements, including half a dozen or so to BT (see the bottom of the linked page).
[Nexus 6P Q&A, Help & Troubleshooting] TechTev:
I use bluetooth headphones everyday and haven't had an issue with battery drain. I'm currently completely stock. 1% per minute definitely doesn't seem right. Maybe try using standard wired headphones for a day and see if it makes a difference.
[Nexus 6P Q&A, Help & Troubleshooting] jerm1027:
I doubt it's the battery. Like other posts this issue only happened after the Oreo update, and batteries don't suddenly lose ⅓ of their total capacity overnight. My battery is 85% capacity, which is still healthy but old. After looking at Better battery stats, I've noticed a 1.56GHz locked CPU state coinciding with my BT audio streaming. It's definitely a software bug. I'm hoping for a solution that doesn't involve factory reset - it'll be a lot of settings I have to reconfigure.

I haven't done any audio streaming at all, but have been checking FB and memes periodically, and I'm at 97% after 3.5 hours away from charger. That's better than Nougat. Will try to watch some YT and internet radio over headphones, but I really need BT audio - it's a major bummer that there is a bug that causes massive battery drain.
[Nexus 6P Q&A, Help & Troubleshooting] v12xke:
Believe what you want to believe, but I seriously doubt it is a bug in Oreo otherwise there would be dozens of other users reporting it in a dedicated thread (not this one). It might be a configuration error due to dirty flashing, or an app you have installed, in which case fully wiping your phone and flashing a full image would rule that out (not a factory reset). Suggesting Oreo has a bug and waiting for a "fix" to come isn't likely to do anything for you. At least use the Android Issue Tracker, report it as a suspected bug, link to it, and encourage others to "star" the issue if they are affected. In the meantime fully wiping your phone is one way you can rule out your current setup. The 85% remaining battery capacity is not helping your case either. Many people have suffered short SOT's and early shutdowns around ~80%. Eventually you will have to do something or the situation will not improve.

since 15-nov, the november update

Today i did the november update security patch. Before i could handle 2 days with the 6P. ( got a new battery because of the known defect ). But today i could just get 10 hours!!! System used 45% of my battery ( 27% google play services ) . I rebooted and am charging now. I hope i will be fixed by a reboot.

---------- Post added at 03:23 PM ---------- Previous post was at 03:06 PM ----------

No its not a software bug. It's a hardware bug, my nexus 6p got a new battery and now have 2 days of battery life on full charge, like it was in 2016-1

Before the battery change: 15 hours and shutdown at 25%

But for now the new software is draining the battery again: BT and GPS = off. after 8 hours only 40% left, screen on 45min., system 45% battery time!
[Nexus 6P Q&A, Help & Troubleshooting] jerm1027:
Denial isn't particularly productive either. There are literally articles the battery life issues on the Oreo update, and there multiple forum posts on this issue, including regarding the Pixel itself on Google Product forums - this issue spans community and hardware platforms. The thing is this update was an OTA update - "dirty flashing" should have been tested as that is how they are rolling out the update. My phone is completely stock (as I use Android Pay and Netflix, and therefore need a locked bootloader and an unadulterated ROM). Furthermore I've had similar issues on laptops with less than healthy batteries, and a sudden decline in battery life was linked to software. In my gaming laptop, MSI afterburner kept pinging the GPU, preventing it from entering a low-power state, and on my Thinkpad, I discovered that YouTube defaults to VP9 codec, which isn't widely supported in hardware, so YouTube videos were decoding in software on my Thinkpad, which is massively inefficient; using a plugin that force H.264 codec resolved that issue. I also don't experience any sudden shutoffs.

As for this particular issue, as I've noted, the culprit is Android System, not any actual app usage. Because this process is hiding under the Android System umbrella and I don't have root permissions, and the default tool is too limited, I can't say what process it is exactly. Before, Better Battery Stats would tell exactly what was triggering a wakelock, but it needs root to do that. Just today, I lost about 18% of my charge with 11 minutes of screen on time - again Android System was at 14% compared to 3% by app usage, and checking better battery stats, I can see 1.56GHz CPU state for about 30 minutes, which is rather extreme (especially considering screen-on time), and that high-power state would explain the rapid battery loss. And the most damning of all is that I actually do get great battery life when there whatever system processing isn't locking the CPU in a high-power state.

I will concede that it isn't strictly bluetooth related as I initially expected (I was able to replicate the issue with local media playback), but it is still a system process, and that is all I can really say with the tools at my disposal.

Here it is, same day, no charging or reboot, and you'll notice a nice flat line until my evening class where I had a presentation open for over an hour.
[Nexus 6P Q&A, Help & Troubleshooting] v12xke:
So I guess you are in the dwindling group waiting for a "fix" to come down to you from Mt. Olympus? For the last two years, every single time *any* update comes out there is a new thread about "OMG, my battery just bit the dust, how about you"? It has come to the point now where even a monthly security update triggers similar posts. When the update came for 8.0, I chose to wipe my phone and install a full Google image- not the OTA. You do have a choice. We have 3 of these phones in our family and none are affected. Please look closely at what I suggested. 1) Wipe your phone and reinstall Android to return it to it's stock condition. If you called Google support, this will always be the first step in the process of elimination.... otherwise you are just guessing. 2) Your battery only has ~85% capacity remaining. Once Li-ion batteries start to degrade they go downhill fast. Replace it if you plan to keep the phone. 3) Please use the Android Issue Tracker! These battery threads just devolve into massive whinge fests and nothing gets accomplished except commiseration. Don't feel you should be forced to wipe your phone and reinstall? ...Don't think you should have to replace your battery outside of warranty? Fine by me. Just sit there and wait for it to come to you.
[Nexus 6P Q&A, Help & Troubleshooting] catintheroof:
Nice one, i agree with you completely, im intrigued to know your thoughts on this one:

Suppose i wiped the phone and installed a fresh google image, but then told google to "restore my backup" where everything magically "comes back to normal" would that be a practice that anyone advise ? or i should put my time into re-configuring everything for battery's sake ?

best.
[Nexus 6P Q&A, Help & Troubleshooting] jerm1027:
That's exactly what I'm expecting. I don't experience this issue on Linux (and even I did, I can easily kill rogue processes), and the whole reason why I'm running stock is for stability, which obviously I'm not getting. If I was running a custom ROM, then yeah, I'd expect some bugs from "dirty flashing", but I'm running stock, non-rooted, locked down bootloader, the least I expect is some actual support and to not into these types of issues. Can you imagine the backlash Microsoft would get if minor security updates required a complete re-install of Windows? I was going to go on about how lazy that solution is, but it's also completely unfair to expect that level of support from this community, and my frustration is entirely misdirected, especially since it isn't a community ROM, so I did star a couple threads in Android Issue Tracker, but I'm not holding my breath. I recently got Moto E4 Plus (a huge part of my reluctance is an irrational fear of not having a phone), so that's going to make the the clean slate more palatable. I'm backing up my data now. I'll consider a battery replacement as well, but prior to the update (still at 85%) I had perfectly acceptable battery life. I'll consider a replacement once the capacity drops below 80%, which, to my understanding, is the effective end of life for a Lithium battery due to the rapid degradation. That, and they don't make it easy (I hate adhesive), so I'm not a hurry to replace it.

Replaced the battery, battery drains normally now(1% at a time) and does not shut off at like 30% but i only get like 2-3 hours of SoT on latest Oreo update..
[Nexus 6P Q&A, Help & Troubleshooting] v12xke:
Yes, by all means use Google backup and restore- it works very well for "store bought apps" and settings. The "trick" is you have to use it during the initial setup when prompted. That and wait until you have access to fast Wi-Fi to minimize the restore time. Also be sure Photos is properly backing up your pictures to the cloud so you won't be disappointed. Good luck! :good:
