Sudden drop in battery performance on my Nexus 6P(no rogue 3rd party apps).

Hello everyone!
So I have been having these battery issues since April security patch. the phone gets really warm to the touch even by doing the simplest of things like browsing and watching youtube. Android OS keeps the phone awake 80% of the time and I am only getting 2-3 hours of use throughout the day. Restored the phone to factory settings(fresh start, nothing restored) three days ago and still the same issue. Android OS drains the battery life even though I made sure that only google apps are installed on the phone.
But today things got even weirder. I disabled Google Now and location services as a test and the battery drain and heat issues were gone temporarily. I was getting a great battery performance from morning to afternoon. I check my battery stats and I notice that Google services mysteriously drained 17% of my battery life and that it's been running for 21 days straight? That's impossible since I just did a fresh reset to the phone three days ago. I rebooted the phone and that "Google services" drain changed to WiFi instead?! That's crazy!
I contacted Google store support team and they have been really helpful so far. They offered to replace the phone with a refurbished unit, but I don't think I am ready to give up on this phone just yet.
Thank you!

I hate to recommend this, but sometimes things go out of wack after a SW update, so a hard reset would probably be needed. I would try that (just start from zero) before jumping into a refurbished phone that might have some other kind of issues. Have you tried a hard reset yet? I see that you did a fresh reset. Did you go through the recovery though? Not just the regular UI. I think it's better to clear cache, and every thing through the recovery (custom or stock).

I did it through recovery. I have cleared the cache and rebooted the phone several times the past few days. Nothing seems to help at all.

Turn off your google backup.

Wow. Maybe a custom ROM might help? Have you tried that? That's the last thing I would do. Good luck!

Not recommended but I just flashed January vendor and ROM and that has helped my battery life. I. Believe it is the security updates that kill our battery.

Is it a widespread issue? Like I said in my post, I saw the decline ever since I got the April security update. The May patch actually managed to make things worse. There seems to be something hidden in the OS that it's draining the battery and causing the awake issues. I haven't tried rooting the device because I lack the experience to do so. I will probably look into it on these forums, but at this point I have tried everything.
Disabling Google now helped a lot and it exposed some sort of a glitch with the stock battery monitoring app. I am not sure if it's hardware or software, but it's certainly not normal. I am tempted to just replace it, but I am afraid that this issue will just plague the new one from Google. I am really disappointed How Google handles updates on this device. I always thought that stock android is most stable version of android, but the software on my old Xperia Z is actually more stable than this. It never had battery drain issues and standby battery life was always great. The battery life on Nexus 6P is actually worse than the Xperia Z even though that phone is 3 years old.

I've seen a lot of posts over the months with people having the same problem we are. I came from a mid range LG stylo with a snapdragon 610. I would have 8 hours screen on time daily. Its sad that goggle cant get the same out of their own hardware. Also I have seen that the Note 5 and S7 Edge both get better battery life as opposed to our stock phones. For as much as people praise stock and look down on Touchwiz, they are doing something right over there.

But it doesn't affect everyone and that what puzzles me. Only certain phones are hit by these issues, while other people are getting excellent battery life. I have seen plenty of people post screenshots of 6 hours+ of on screen time. I am lucky to get 3 hours. I think Google should really invest in creating a better power management system into Android. Companies like Sony and Samsung built their own and the battery life on their devices always perform predictably relative to what I am seeing on this phone. I have never witnessed The doze feature kick in since I have bought this phone. Sony had stamina mode since 2013 and it actually worked.

Most of those people posting those outrageous number root and do kernel tweaks. I've gotten at most 6 hours SOT on stock without root. You are right our phones do all react differently to certain circumstances. I don't know if it's feasible to you ,but you should try rooting and trying out a few Roms some help others don't. If you aren't into Roms and decide to root try earlier vendors and stock roms and see it those work. I'm not an expert by any means just my suggestions.

Well, the fact that you are having great battery life proves my point. It's either that the quality control of the batteries used on these phones are terrible, or that the software or kernel are corrupted from factory causing these issues. There is no way to fix them by hard reseting the phone so far. I am going to try to flash a stock rom on this device and see what happens. Thanks by the way.

1) Are you rooted? If not, at least do that and install BBS in order to track down what's eating your battery.
2) Probably we'll run into a common problem / bug the last two months.
After unplugging the phone, it seems that the wakelock *backup* runs constantly, does not let phone get into sleep, and runs in the background while using your phone causin battery to drain faster.
3) About battery life. Comparing battery results between two users it has no point, unless you really now his usage pattern. Not only the setup, but which apps of them used most etc.
For example Facebook app is real battery eater. I've seen an hour more SOT without this app.
I can give several examples like this.

Same here, I've been digging through articles most of them are the same. But there's a comment said disabling Automatic System Update fixes the issue.

And where i can disable this automatic update ?

You can find this in the developer settings. (You get there by clicking on the build number 8 times and it then shows up in your settings menu at the bottom.) Its weird that these Google devices keep getting this battery drain issue. Its so frustrating, you would think they would have this solved by now with the system going rogue thing.

Thanks man i will go test it ....

Hmm ....little bit better but still draining a lot ....... then 6.0

Stock DP2. I'm having solid battery life.
You guys should try doing a clean install from the factory image.

Mine was fixed by the battery replacement and been having 4+ hours SOT so far. Check this link http://forum.xda-developers.com/nexus-6p/help/how-solved-battery-draining-problem-2-t3506071

Android System and OS are still at the top of battery usage. Which shouldn't really happen

They are not at the top, Screen is at the top and system is below it which is what I would see on MM as well.
People are way to concerned about where Android System is on the usage list.... Does it really matter if you're getting solid battery life that's just as good as MM?
Also, if you're not aware, System and OS are probably going to show higher usage when compared to MM no matter what.
I'm pretty sure battery stats are calculated a bit different in N... If you go check out the battery life threads in the Pixel forums you'll see plenty of screenshots that show similar System usage.

Sadly I am not getting as good battery life as I did on MM... I've tried everything I could to improve battery life on N. My only option now is to move back to MM, which I am very tempted to do but rather not because everyone's moving to N, or replace the battery itself. The latter is probably the next thing I'll have to do. Right now I have to baby my 6P around just to get decent battery life out of it, and that honestly irritates me.

Axon 7 A2017G Android 7 Battery drain

Help...
The Battery drain is too much... how to fix it?
Everything was doing great in android 6.
how can I downgrade to Android 6?

Which version are you using?
If you use the beta 7.1.1 then don't post bugs like yours.
Wait for final version.
Before that do a reset and test your phone again.
Otherwise look also for apps like wakelock detector or better battery stats in its alarm section.

I just updated my ZTE Axon 7 (128gb Internal Storage - 2nd resubmitted) Android 7.0 to Android 7.1.1 and now, my battery is RAPIDLY DISCHARGING! EVEN WHILE ON THE CHARGER! I wish I could revert back to 7.0, but I fear that cannot be possible without performing some sort of technological gymnastics and a Pagan Ritual. I'm really stressed, here.

I had this too. Let it discharge and shutdown. Than recharge your phone while powered of. Problem solved.

I've always had terrible battery life with this phone. Why is this software so bad. Also A2017G Nougat B01.

Maybe some issue with your signal or configuration, because with my phone I can get easily 4-5 SOT and at least one day of usage with everything synced, WhatsApp, 3 mail accounts, GPS, Google Now, etc.

Yeah signal is a big battery drainer, I have low signal in my home and my battery drains like hell, I always keep the phone on charger when I'm here lol.
Once I'm outside though my battery drains much slower.
Fricking network providers and their weak ass antennas, haha.

I don't even have a SIM card in. I just use the phone for gaming.

I probably have something wrong with my unit, becouse it seems like the battery is perfectly calibrated on 7.1.1 and no draint whatsoever, today managed 6h of sot, with some antutu, youtube, play store downloading, 4g+ and snapchat going on. I mean now when i lock the screen on certain % it stays, but on mm it dropped 2-3% after locking

I have the same experience, is going really good so far.

Hmm time to refresh old post.
A2017G B04 full stock.
Since I got B04 my SOT dropped from ~5h to 2,5-3h. BTW. I already tried factory reset, cache cleaning from bootloader - no positive results.

Same with mine... Some reported it's due to bad cell signal is causing battery drain

Battery life on Oreo

I flashed the stock image and i found the battery life abysmal. Not even a day
7-8 hrs tops with barely any usage
Anyone has experienced the same issue

Give it a few days and see if it improves. Sometimes drastic updates can have adverse effects on the battery

I have one of the best battery life on O right now and I'm not pointing fingers to anything but google.
I was excited after hearing "Android Vitals" and they are on point about it.
Try to flash a custom kernel like EX or Flash though Ex's kernel isn't fully committed with the O source code but you may at least try it. On a side note there are still apps out there that aren't coded properly for O which would probably hinder your angler so look out for them a lot.

Thank you everyone for pitching in
Like I mentioned I flashed the stock image and gave it 2 days but as I disconnect the phone from the charger at around 9 AM (100%) , by 3-4 PM I am being left with 30% or less . By 6 PM it starts beeping as it hovers 15%
I barely use the phone at work. I just do occasional messaging (text and whatsapp). I removed all apps except the ones that I really need. No games...etc
I did flash the other day the EX Kernel ( Beta for O) for which I have the paid manager version.
It drives me crazy as it seems to be draining at a very fast rate with no apparent reason.
What's even more frustrating is that the built in battery app doesn't shed much light. The process that takes the most battery is "System" but that's all.
Maybe it's time for a new phone

Yes, I went back to paranoid nougat, because I got the same
battery experience as you with O. But I'm reading that you use
what's app, do you can play a video if someone sending you one? Since the O previews for me the videos are just loading but not playing, and that's only the case by using android O, doesn't matter if I use what's app or what's app beta.

I got the 2% battery drain bug and sometimes i dont, ive reflashed oreo about 8 times lol, sometimes it dies at 15%..

I haven't had any issues with any of the apps. Whatsapp works well I can play videos see the pics etc

I read somewhere I needed to flash first the Nougat stock before attempting to put any custom ROM. Is that what you did?

No, just my twrp backup, you can stay on latest bootloader and radio. Strange thing with whats app, may oreo doesn't like my internal, if final release come I will complete clean flash with fastboot.
Edit: check latest Pixeldust rom, it's like pa with a bit more useful features

I think my phone may be defective
Even on Paranoid the battery seems bad
The miscellaneous was on top of the list . What does that mean .... ?

Battery update.- Running kylo kernel r9 , working great so far just a few personal tweaks applied.

I'm not sure what you're expecting, give the rom some time and charges to settle battery. How old is your phone? If you don't have patience flash stock image and completely wipe your phone if you think something is faulty.

Well...
I used to get like a day out of the phone . With my minimal usage I would disconnect it in the morning and still have like 30-40% when getting back home in the evening.
All of the sudden one day I was just on my way home and I noticed the phone was off. I tried power it back on but it kept on flashing red as it was totally drained. Since then battery went downhill.
I'm not crazy and I do not have unrealistic expectations but 5 or 6 hours of battery with almost no usage seems a bit off. I gauged just by looking at the numbers being something ridiculous like 10% an hour.
I did wipe and flash the stock few times. Oreo then Nougat
Since the issue persisted I am thinking the phone just went bad.

If your battery is faulty, then it's faulty, that's why i asked how old your phone is. Ain't there battery health apps to take a look how worse it is.

Yeah I think it's maybe 1yr and half old.
I'm starting to evaluate those Essentials and Pixels 2.
Or better get a Pixel 1st gen if they drop low enough

Sounds to me like your battery is worn out. I'm amazed that you got 1.5 years out of it because I've seen posts from people who didn't even make it a year. You mentioned that it's draining 2% at a time and shuts down at 15%, which are pretty strong indicators that your battery is shot.

Nokia 8 (pure android) is an option too, but I would change the battery, n6p is still a very nice piece of hardware. Essential
is a hype phone til now.

Do you have a trusted source you can share for a battery?
There are so many floating around and I'm not sure about their quality

Hard to say, I will run accubattery for week, after a first charge it doesn't look very promising for me too, and my phone is a bit over a year old. may some other users know a better tool or app, but this one doesn't seem to be so bad. Let's see what happens after some charges.
Akku Gesundheit=Accu Health, sry it's german here.
If you search for a replacement there is a thread here on xda
for the 6p, OEM battery or something like this

Same for me, with Oreo it's even worse

Update, kylo kernel r9, works fine however my phone now dies at 5% instead of 15%-20% much better but still.

Oreo + stability update

Hi,
I have been using this phone for a year now. I really feel we got more preformance after oreo. The phone is pretty smooth after all the hassle. I do think we lost a bit screen on time with the os update. I feel that is many times the price of getting more speed. Anyway i tried for a while my G4 rooted + optimized. My conclusion is that optimized + sabs and non rooted s7 edge is really fast phone. I see no lag. I feel this phone has a year left in it and thats actually impressive knowing its 2,5 years old.
I tried Oreo without factory reset. My experience was that some of the apps did not function well. So i did the factory reset and all works now. I think its only smart move after os update. Now i will just clear system cache after minor fixes.
The last as good deal was lg g2 to me. Love your phone still its in the competition with never phones. After year i bet we see improvements that will make many of us consider changing to a next generation of phones.
Btw. Did anyone else get the stability update after oreo? What do you guys think of it? My feel is that now almost 100% is working and smooth as a butter.

I have moved back to nougat and stayed there for now, i did not mind the cell drain as it still lasted me all day, however i had random reboots as soon as i moved to official Oreo or even custom rom with 8.0 base, did not matter what i did the reboots would get worse over time. I moved back to nougat and not one reboot experienced, Oreo for me is good when it worked and would love to use it but drove me crackers when rebooting. SM-G935F

This is actually intresting. My phone did random screen freeze and couple of reboots in nougat, but on Oreo that is not happening to me.
But i do definetly have the cell drain still after the last update. I kind of woke up by the fact that i have lost about 1h screen on time. Yes i am a heavy user so thats the first que for something is eating the battery.
What kind of cycle your battery lasts average and how is your SOT on nougat? My is average 27hours on time hours and sot 5-6 hours

I am unable to advise you on SOT as i don't monitor this, i am running a custom rom with nougat base (Sac23 S8 port) i have a battery life of between 29 and 32 hours, never really goes past 40% remaining at the end of the day.
