Google Pixel 1 battery troubles - Google Pixel Questions & Answers

Hello all, so the original battery on my Google pixel, almost 3 years old, went to complete hell. It turns off in about a minute once unplugged, despite 100% battery life. So I went and replaced it with two Amazon bought batteries. The first one (definitely not OEM) had the same issue but my pixel would at least last about 10 minutes of regular use, unplugged, before shutting down. So I thought it might be the battery but the second one has the exact same issue. The second one at least looked like OEM with the exterior but since it came from Amazon, it's not 100% certain.
The problem is that the phone charges very fast, like 100% in less than 15 minutes and then discharges 10-20% in just a few minutes. If I last below 70% that would be out of the ordinary.
Is it possible that it's not a battery issue but maybe a different issue? A friendly person on another forum suggested that my core or graphics IC is overheating, attempting to throttle down; and then just shutting down when it looses the battle. Which makes absolute sense since the phone mostly shuts down when I'm playing games on my phone and usually turns off just under 80%.
I also found out that a recent google play store version was found to be the culprit for the extensive battery loss for other folks. Could this also be reason?
Are there any tests I could do to further determine the actual cause?
Thank you.

Two ideas:
- Deactivate Play Store app in Settings -> Apps & Notifications -> All -> Play Store -> Deactivate
- To rule out a damaged third party app as a cause for the battery drain (which actually is quite unlikely in your case), you can reboot into safe mode. For that, long-press the power button and then long-press 'shut down', confirm with OK. At the reboot, all non-system apps are freezed. Then you can check if the battery behaves differently.
Did you try charging your phone for about two hours longer, even if it says it is already at 100%? Maybe just the battery percentage measurement system is somehow damaged.
But you already tried that I guess. So maybe somebody else got another tip for you.

do you try flashing stock image? maybe the battery cache is in trouble

Similar to OP, my Pixel XL had started to have some odd issues beginning almost a year ago. It got REALLY bad in just the last six weeks or so when it would shut down at relatively respectable battery percentages (something like 23% - 57%, randomly).

Thanks for these ideas, BenjyTec.
When I deactivated ("Disabled" in my settings), there was no change in behavior. In fact, I had forgot I did that until giving things about a week and had forgotten when the phone behaved the same way, LOL (I just now re-enabled it).
I also tried the Safe Mode (which I had not previously known about - thanks!), and the phone still died out pretty quickly from a "full" charge.

I had also done this several times. The really odd thing is many times I will have it on the charger all night or for several hours, and when I take it off it is only at a very low percentage - from 1% to 16%. !!! Of course more often than not it does get to a higher percentage.

Thanks, gonzakennyn - I have not done a "stock" image, but have factory reset the phone, with no joy. This was actually one of the things I did months ago even before it got really bad, because I wondered if maybe the battery cache or something at the kernel level had deeper issues.
Hopefully the OP might have had better luck or found something...

All these complaints sound like power supply issues.
Use the phone while it's in the charger, and there's no overheating/throttling/shutdown, right?

Unfortunately, I did not find a solution. After replacing the battery twice I pretty much resigned to my fate. I'm going to hold out until Pixel 4 comes out.
Once fully charged, I could use my phone for browsing or watching videos for about an hour before I get to around 30-40%. Then I could leave it unplugged all night and wake up to my battery at 1%. It actually stays that way for a bit.
However, if I use my phone to play any games, I could only use it unplugged for about 10 minutes. My phone will power down without fail at 80% or below only when I play games. Weird thing is, whenever I power it back up, my phone will be 1% but despite that it could last quite a while.
As post-mortem mentioned, I could use my phone while charging without issues so maybe it is a power supply issue, in which case, I have no idea what I could do.

When it's not plugged in to a charger, the only power supply is the battery. Hence, I feel that even your "new" battery is not new.

So a little update all. I updated my phone to the latest Android 10 patch and the battery life has gotten significantly better. It's still not enough to last all day but it can last probably 6-8 hours with minimal use. If I use it constantly, it might last two hours.
I am no longer tethered to my charger when playing games, which is really good news and all the prior issues with the phone shutting down ~80% is gone.
Perhaps the previous Android patches contained faulty code?

I would do fresh install and see if problem resolves. Fresh install fixes all sorts of software issues.

So my battery woes aren't as bad as yours but I did get to the point where I had the battery replaced. I went to uBreakiFix and I have no idea what battery they put in but the bottom line is a brand new battery didn't help much. I got a little better battery life but not as much as I had hoped. I'm assuming that it's either due to the apps I have installed and my usage or the phone is getting old and something is drawing a little more power than it used to. I have not gone to the trouble of factory resetting to see if that would help yet.

Factory resets didn't help my old issue. Updating to the latest Android os helped immensely. As stated above I no longer have the initial issues. I estimate I now have about 70-80% capacity, which is not bad at all considering I bought my battery through Amazon for around $20.
I thought if you got your battery replaced at ubreakifix, then they are obligated to fix your issue or refund you your money.

[Q] Sudden (strange) battery issues

I've had my nexus s (9020a) since late November (bought it used, in execellent condition.) While battery life was never awesome, it was at least bearable - until last week. I'm now unable to get more than 6 hours on a battery with super-minimal usage. For instance, today, as of right now, I have 5h 58m 57s (at 7% battery left) - the top "user" being the display (32%) with a "time on" of 17m 30s. Even when I power the phone completely off (not the screen, literally powering off) - say for a half hour or so - when I power it back on I lose substantial amount of battery.
Some other details:
Currently running stock 2.3.6 rom (since yesterday), but rooted.
Previously was running stock ICS (flashed the tmobile 2.3.6 ota, then ics, then the att radio) - was fine for the last 2 months
Tried brand new battery (not a samsung, but Anker) - no difference
Tried several different charges, and charging via computer
Have wiped battery stats several times (and done complete resets/formats of everything in between swapping roms)
Phone used to always top out at 95% when charging - but now will go up to 100%
This behavior started up when I was on vacation - a few hours after landing in SLC, UT. I do recall a sudden crash / reboot of the phone before the problems started - but I have gotten random reboots in the past. Was running ICS at the time. I thought maybe a poor signal was to blame, but again, the battery would drain even when the phone was powered off (or in airplane mode.)
I'm not sure what else I can/should do - short of calling Samsung. I'd think if it were a hardware issue, it would fail to charge completely. Does anyone have any other ideas or suggestions?
Thanks in advance!
Sounds like something external is draining the battery. I've seen many cases with a magnet on them drain the battery very quickly, or possibly excessive heat. If not i would say it's some kind of hardware problem.
Does not sound like android chewing it up.

I don't have a case on it - just a screen protector. The battery does tend to run in the mid 90s fahrenheit (according to battery status apps.. though I think I have seen it as high as the low 100s (maybe 102?) - but I figured that was normal.
Another weird behavior I should mention: sometimes when I power off and on while charging, it will cause the battery percentage to jump considerably. Right now, two consecutive on-off-on cycles (within the span of 3 minutes) caused the battery percentage to jump from 36% to 44% to 57%.
Heats normal. Not sure what it could be to be honest. Maybe grab a can of compressed air and spray around the back, maybe dust causing a short or something.

Thanks, will try that
Sent it back to Samsung for "repair". As I suspected, all they incompetently did was re-flash 2.3.4 and say "passed all functional testing". Phone is still hosed and completely useless as-is.
(Fully charged, overnight - less than 8 hours - went down to 17%, with no apps running, no google accounts, no sync, no background anything, no screen time, no wifi, in airplane mode)
Samsung really is hopeless. Going to try again with them? Whatever you decide, best of luck. Hope it works out for you.
what is the mv reading when the phone is fully charged? Fully charged should be around 4200mv

Trying again, but not optimistic. I talked to about 4 total "customer support" people today.. at least got them to "upgrade" me to 2-day shipping for sending back and forth instead of the normal ups ground.
It is so foreign to me - coming from Apple where, under warranty, they'll pretty much swap problematic devices out for new ones _in store_ on a dime. I pretty much begged Samsung to just send me a refurb unit to replace it with but they said thats "not their policy."

I don't have it with me (send it back for round number two) but I am fairly certain that is around what it was reading.
The thing would even burn through battery when powered off, if the battery was still left in. Taking the battery out = no drop. It has to be something hardware.

[Q] Battery Problens!!

Ive had my htc one x for maybe 5-6 months which is almost the longest ive ever been on one phone and i love(d) it, but its always been doing something very strange and aggravating that seems to be getting worse. Battery drain has always been a problem for me with this phone but ehh i can deal with it, but once my phone gets down to about 14% which is does often because of the draining it starts acting real funny with its power and sometimes goes from 14 down to 5 in an instant literally out of no where and as soon as i plug up itll go right back to 13, or itll shut down entirely at 14% but i can just cut it back on, or itll shut down in the middle of me doing something and i have to charge it for about 5-10 minutes before itll even come back on. The latter happened last night btw. No matter what combination of roms/kernels i try this always seems to be a problem. I really cant deal with this anymore and its to the point where i wanna throw my phone into a wall and just buy another one, which im seriously thinking about doing at this point. If such thing has happened to anyone before or you have insight on this can you please help before i just give up hope completely.
What you have described is normal for our device. Remember that the battery percentage is just an estimate of your actual charge. In addition, you find your phone shutting off around the lower percentages as a result of the device attempting to prevent damage to the battery. That is what the HOXl was designed to do.

Last night when it did it, as it has before, i was still on 21%.... thats not normal. And this isnt my first android nor first htc, never happened before. Even on my aunts old one s it didnt happen
Do you allow full charges after these "forced shutdowns" occur? This should cause your battery to recalibrate.

The battery behavior on this phone has been interesting. I have the battery last over two weeks on airplane mode and I've had the battery last just a couple of hours with just a stock setup. There are so many factors that play into this. I work in an area with very little to no signal reception and my battery life goes crazy and the phone can get really hot while I'm there so I've seen the best and worst.
What I do to counteract this bad behavior:
1. Charge prior to 40% (I've had the phone go from 40% to zero instantly before)
2. Consider your signal reception and either try out different radios or use airplane mode to reduce erratic battery drain
3. Install a 3rd party app like batterycalibration (https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=en) and use that when things get hairy (I calibrate every two weeks or so and that does the trick for me.
My phone has been like this since I pulled it out of the box. With a little management, it is just fine. You have seen it before but I'll say it again, you have to get through a few charge cycles when flashing a new Rom to get back to normal.
Hope this helps. It works for me and I work in a cell phone reception hell.

When a new ROM or kernel is flashed you need to let battery settle for at least 48hrs before you get super worried about battery. If possible during that time let device fully discharge then charge up to 100. Please use a battery monitoring app and then see what's causing the issues. With proper config hoxl will get good battery life. There is always the chance its hardware issue but doubtful as battery prolly would of completely failed by now. Also check your screen brightness settings. Hope this helps

Ive done all three methods youve mentioned before and still same thing. Also im on 3/4 bars with lte 90% of the time so no reception issues here. And with my current setup ive been running it for about 2 weeks.

Ive always let the rom settle in and i constantly maintain the brightness on around mid level (mirror screen protector so i cant go too low) but its not just one rom or a few, its with every rom i flash ad that consists of most roms available for this device
The battery behaviour you described is completely normal if you understand how a battery of this type works, and if you understand how the software (especially the display of battery percentage) works in conjunction with it.

So youre telling me having the phone get to 22% and instantly drop to zero and power down is normal? Makes no sense at all. Also i cant get it to charge too 100% for anything. So if theres no fix to this, anybody want a one x with a troublesome battery?
What I'm saying is the battery percentage displayed by the software is never exact, it's only an estimate based on the voltage level of your battery. Your battery sounds like its long term life (capacity) has been decreased over time and possibly bad treatment (allowing the device to discharge too much too many times).

Depends on what you define as "normal". Such behavior is certainly not unheard of (although you particular collection of symptoms may point to a more serious issue, which I'll get to later). Couple things you have to remember: the battery meter is far from accurate. Being off by 10% or more is not unusual (completely normal). So jumping from 5 to 13% as you mentioned is not out of the question. The battery voltage is not actually jumping around, just the % battery number that the phone is assigning to various voltage readings. Reading errors happen, and if a jump is noticed, its just the meter correcting itself.
Which brings us to the other point that should be kept in mind: the battery % is not a "real" measurement. Its just a number assigned to various voltages to give the average person a sense of how much battery is left. Its a completely fabricated and artificial measure that just gives some relative sense of when a user should charge their battery. Phone makers just decided to use a system that average people would understand, like the fuel gauge on a car. Zero doesn't really mean zero (or anywhere close), but reporting in voltages would make no sense for most folks. Also, as we all well know, just because (for example) it took you 12 hours to drain the phone to 50%, does not necessarily mean the phone will last another 12 hours to drain the remaining 50%. It all depends on what you are doing with the phone during that time. Which leaves the question: What does the % battery really mean? Really, not a heck of a lot.
On the other hand, the battery failing to charge to 100% is troublesome, as is the apparent frequency of the meter drops and the fact that the issue remains after various ROM flashes. Leads me to believe there may be some hardware issue going on.
The short answer: IMO while some of the individual symptoms are not unusual, the seeming frequency (you haven't exactly quantified this, but it seems relative frequent just based on your descriptions) may suggest a larger issue, but its not certain.
Thanks it explained a lot but it happened again today, went to the store with ~36% on the meter and walked out, haven't touched it at all, phone was completely dead. Tried to charge and it went to 6% and stopped charging, all signs showed it was charging but it was stuck on 6. Then it started climbing again and reached about 16% and actually started losing charge while on the charger. Switched over to my portable battery charger i just got and it held the charge at about 5% for ~30 minutes, which is what it was when i plugged it in and started to charge, then it stopped againand during the whole process the phone was getting very hot. Yea im getting a new phone :/

Weird behaviours of my N5, hw or sw problems?

Hello everyone, I'm having problems with one of my nexus 5.
One month ago I flashed Resurrection remix ROM with no problem and I used it for many weeks.
Something around 3-4 days ago I let it switch off to make a battery cycle and I didn't touch it until the next morning. When I put it on charge, and after waiting for 30 mins, I tried to turn it on with no success. I tried to connect it to my power bank, which has LEDs to verify that is charging, and I discovered that that wasn't happening.
So I took off the back cover and tried to check, moving pieces, if there was any hardware problem. After that the phone finally turned on and was able to charge but since than I have some serious problems:
-while in standby it rapes the battery, in 30 minutes consumed 11% of it with no apps on; with screen on instead it's the opposite, I watched kung fu panda 3 at 100% and at the end of the film (1h 20mins) it was at 86%
-when I go to sleep if I don't keep it attached to a power source in the morning I find it switched off, and when I turn it on I discover it has still around 20-30%
Sorry for the long post but i wanted to explain in more details I could the situation I have.
Does someone of you know what the heck is going on with my N5? What can I do to fix this thing?

Is your battery life when you use your phone your only problem, no other things you notice that aren't what they always have been? If not, probably your battery is dying. Replacing your battery will most likely fix your problems.
Everything works fine except the things that concern battery inputs or i/o of the phone. Is there a way to check if it's actually the battery the only problem?
I'd rather avoid the situation where i buy a new battery unit and find out the system is joking me someway.
I was wondering, is it possible that those problems are given by an accidental bad settings in Kernel Adiutor?

Well if you want to check it on the software side, you could take a backup of your current setup, store your important files and the backup on a PC and flash a factory image. Then you can check and test if you have the same problems on a clean setup. It could indeed be wrong kernel settings but to me it sounds like your battery is just dying. That's not weird if you take a look at the release date of this phone.

Battery life greatly getting worse

Has anyone noticed their battery getting incredibly worse over time? I bought my S7 on release (non edge). And since then, I've noticed that it doesn't last no where near as long. Today, for example I started my day at 7:00am when the battery was 100%. As of 30 minutes ago, the battery reached critically low (5%). From 7am all I did was watch a few videos, facebook, snapchat and then play music. But all the above for not too long.
I've also noticed that once the phone hits the 15% battery (I know due to the notification), that within minutes the battery can be done to 10% or so, without touching it.
I'm more so tempted just to take it back, unless there's an easy fix OR it's a known issue with the current version.
Thanks!

I've definitely noticed this since rooting. Maybe it has something to do with that? Like a ROM you flashed or what not? I'd like some suggestions here as well.

I haven't rooted the S7, it was the first phone that I've left stock from opening.
What does the battery stats say is using the most mAh?
Facebook app is a known battery hog
Obviously over time, you'll install different things, and slowly the phone will start using more and more power running background apps
A backup and Factory reset will show if there is a hardware / battery issue, or if it's purely from stuff you've installed over time
Also clearing the caches from recovery could help
yeah ive noticed this too. My usage habits havent changed but my battery life is almost half of what it was when i just got the phone.

Cache has been cleared from recovery, and I don't generally install many apps so since I've bought the phone the apps have stayed the same.
Android system is always on top. Unless of course I spend hours on Facebook.
Might have to factory reset. I've used my phone with the same apps and time since I've bought it, and I'm finding I'm charging it 3x as much.
I think it's a root issue - deep sleep.
After S6 Edge Plus, when you root a samsung phone, it won't go in deep sleep. I believe there's a fix for that.
Have you checked the battery usage stats? It gives you the breakdown on what apps are eating up the battery.
I have had my S7 for about a month and battery is about the same.
Just to update this thread for those that may have a similar issue...the other day I couldn't live with the battery life the way it was. The phone used 50% in several hours where I barely used it.
Decided to completely re-flash with stock (was stock before) as opposed to simply wiping all data. A week in, and the phone's battery life is back to the way it was. I went to bed when it was on 100% (as a test) and woke up 7 hours later with the phone on 94%, with wifi, location and bluetooth on.
Not sure what had caused it to use so much battery previously, but it's back to what it should be and that's all that matters.
hi with my s7 exynos i do 3h screen. i think there is a problem. i bought my s7 one week ago. can anyone help me?
Rooting and installing custom kernels when done right should greatly increase the battery life of your device. This is a well known guide here on XDA for improving battery life for our devices.
That being said, Lithium Ion Batteries hold less charge the more cycles they are put through, its a given fact but as you said your device is relatively new and therefore should not be experiencing this kind of problem. The way I see this is there are 3 possibilities which may be causing the said problem...
1) You have rooted the device and done some modification/s. ( which you haven't done )
2) Your battery is being drained by a service ( Like Oculus or VR ) in fact a number of reddit users complained their S7 was overheating and battery was draining really fast for some reason. Check This page out, It might help you.
3) Battery Defect, you must've gotten a "bad" model, if you haven't tripped KNOX you could try bringing your phone to Samsung and see if they would fix or replace it.
Good luck
I think this has to due to them samsung updates. As far as i know samsung been always doing things like this where they made the OS slow as hell after a while so you gonna get a upgrade sooner but a battery should last 2 years minimal without degrading.

i get like 5 hours screen on time and bout 1 day standby time but i have most bloatware disabled with the package disabler. But if i was you i would contact samsung.
This happens with Samsung updates on every Galaxy phone. It's like a curse. It's unavoidable.

May i ask if the people with these problems use the fast charge? I hearing many bad things bout this so i switched it off and must say the normal charge isn't that slow and if it can keep the battery good for longer then we all should use this.
I turned fast charge off about a week after I got the phone, was making the phone and charger pretty hot for the sake of about 5-10 mins quicker charge
Pointless really, unless you are desperate, only have a few mins spare and need as much power as possible in that short time, and if that's the case, enable it for that one time
Restrict background data on all but the most important apps (phone, text, email), dave power all but the most important apps. Battery life is fine

Battery draining insanely fast

Hi
All of a sudden my battery started draining rapidly. See the attached screenshots for ref. I thought maybe it was a software bug since it started happening 2 days ago. I tried booting into the safe mode and the fast drain didn't stop. I also did hard reset with same result. At this point I'm thinking about getting new battery. Just wanna see if xda community has any tips if maybe I've missed something. It's just strange that this sudden degradation happened overnight.
Obviously, that draining is not normal.
In the upper left corner there is a warning that some app is running in background.
When you did the hard reset also you did a restore from some backup? Is the device warm/hot?
Sometimes it shows carrier utility or people apps running in the background. I restored from Google backup (forgot to mention in the OP). Device isn't hot at all.
i stared clean with LeeDroid ROM (had original Sprint ROM on) after wiping the data and the fast battery drain remains. at this point i'm going to replace the batter since it's not a software issue.
I'd definitely say your battery has shat itself. I'd also try something like gsam or battery info in *#*#4636#*#* to see the health of your battery. I'd be interested to know if it reports it as "good" health
It's strange but the standby seems to be better now whereas it was going fast before. Thought maybe it 'fixed' itself, however during a phone call (4min) I lost %3. That's definitely not normal 4636 is not showing any battery info. Can't find anything in gsam showing health status of the battery. Is it in pro?
If the battery drains fast during calls can be due to poor/weak network reception (the modem tries to maintain the best quality and scans the network over and over).
3 sot with 50% (or little more) battery left is a good value, in my opinion.
Oh, when recoveries are made due to some problem is better to not restore from backups. In that backup can be the app or setting that is causing the problem.
Anyway, with the last google play services (14.7.99) I also have noticed a bit more drain during standby.
Sounds like you need to replace it

I have about the same issue. The battery is draining too fast and it's very noticeable when idle, even when idle in safe mode + airplane mode it loose 20% during an 7 to 8h night. I tried all htc nougat and oreo official and unofficial roms and nothing fixed the problem.
I also used the htc diagnostic tool to determine whether my battery is "good" or not and..... according to the diagnostic tool it is "good". Notice that according to diagnostic tool the battery is defective only if it goes from 100 to less than 75% during the test. Mine goes from 100 to 93 during the test which consists in showing a kind of dark grey screen at full brightness during 1 hour.
Even with a battery rated as good I decided to sent my device for repair because it was not good.
I received the device back and it has not been repaired because it passes the diagnosric tool test. test.
So i'll replace the battery myself as soon as i'll receive my new battery.
I suggest you to run the diagnostic tool test and if you get a decrease from 100 to less than 75, they should repair it under warranty, if not, suggest you to replace the battery yourself or pay somebody to do it for you.

I already ordered the battery and will do the replacement myself if the wait times are similar to those of screen replacements. Plus everything points to a bad battery so another test with official app is pointless. Sounds like we both will be doing the swap ourselves.
So I put new battery in and the drain seems slower than before and the charging is not erratic (jumping). When I was removing back cover the black layer came off so I figured it'd be good time to try clear cover mod . I like the look but unsure if anything will interfere with the radios and such due to the missing protection.
