I just had a new battery installed in my Pixel by Ubreakifix because my battery had been draining quickly. My problem is that the battery continues to drain quickly even with the new battery. My understanding is that they install OEM batteries so I don't think that the new battery is the problem.
So, I tried to calibrate the new battery using these steps found here:
1. Discharge your phone fully until it turns itself off.
2. Turn it on again and let it turn itself off.
3. Plug your phone into a charger and, without turning it on, let it charge until the on-screen or LED indicator says 100 percent.
4. Unplug your charger.
5. Turn your phone on. It's likely that the battery indicator won't say 100 percent, so plug the charger back in (leave your phone on) and continue charging until it says 100 percent on-screen as well.
6. Unplug your phone and restart it. If it doesn't say 100 percent, plug the charger back in until it says 100 percent on screen.
7. Repeat this cycle until it says 100 percent (or as close as you think it's going to get) when you start it up without it being plugged in.
8. Now, let your battery discharge all the way down to 0 percent and let your phone turn off again.
9. Fully charge the battery one more time without interruption and you should have reset the Android system's battery percentage.
I seemed to get caught in an endless loop on step 6. After charging the phone to 100% on step 5, I would disconnect the charger and restart the phone. Every time the battery percentage would drop to 60 or 70 percent after restart. After doing that about 5 or 6 times, I gave up on that step because it didn't seem to be making any difference. One cycle of doing this tends to take several hours because of the charge time from 60 percent to 100%. So, this ended up being a many hour process. Should I have just kept repeating step 6 over multiple days in the hopes that eventually after many charge/restart cycles it would eventually register 100%?
Now the battery calibration seems completely out of whack. I have fast battery drain and the pixel shuts off sometimes around 30 or 20 percent remaining battery. Now with minimal screen on time, the battery might last 8 hours. It used to easily last all day even with moderate screen on time.
Any help would be much appreciated!
I would take it back to Ubreakifix. Tell them the battery drops from 100 to 60-70 after a restart. It sounds exactly like what you would expect from a bad battery.

Yep did that already. They replaced the battery again (for free) and still the same problem. The technician said that this has been a common problem for many pixels after they’ve replaced the battery. He claims it’s because the pixel can’t handle android 10 but I don’t believe that.
I recently bought used Pixel and Pixel XL.
The XL exhibited the exact problems you mentioned (looping steps 5 and 6 and shut off at around 20% mark). Even have this on camera (btw, split screen opening some games like PUBG with your battery status on the other side is a good way to drain the battery and show battery percentage). Not sure if the battery was previously changed but I took it back to the seller and got a refund.
On the other hand, the Pixel (non-XL) is running on Android 10 just fine. Did the battery calibration as you mentioned and it was good to go.

I know there are a few threads on the battery levels being a bit random at times, but mine is really hacking me off.
It will stop at say 75% and just stay there, when I reboot its down to like 50% or less. Twice now its gone dead because I though it had plenty of charge but just wasn't moving.
Is it the phone or battery thats the problem or drivers or something - ps this is on a standard rom, no tweaks etc.
same here.im using romeos rom but it seems to be a problem with another roms to.the battery % stay (for example) 10 hrs 68 % and after reset dropt 5,10,15 % down . is it hardware problem or software ?
And quite same here... The case is a bit worse even. When I charge it from lo-bat warning to full, it sort of overcharges itself and might hang up even! I noticed this in two phases - 1) when I left my TP to charge during night, it was hanged in the morning 2) when charging from lo-batt and restarting at ~85% bat level, after boot up the battery reports something at 98% or something!
I have the same (all posts) some time I have 78% and make reset and now i have 89%. Which is real 78 or 89%!??
when I charge all night I have only 70-92% after 6 hours, and after reset 100%
For me this is unusable as I cant trust it without constantly rebooting which is not good enough.
Lucky for me its a second phone, so I'll flog it and think of something else.
Hi there!
I have the same problem, after charging over night. The battery indicator shows, that a battery is not fully charged. After short removing battery and rebooting it shows 100%. With another HTC battery it is the same. When I use another spare battery (not original HTC), it works correctly. But I dont like the spare battery, because it is hard to remove from device because of its sharp edges. I think, it is a HW problem of battery, or a problem of device.
Seems I fixed mine. I had put an extended battery on this guy, and it would never change in battery level. I would have to reboot the phone to get it to register the new power level.
Discharge your phone to 0% until it shuts off. Try to turn the phone on several times to make sure its discharged (should shut off immediately). Charge the phone to 100% without unplugging it (will take a while, do it over night).
Today my % seems to be registering and no need to reboot the phone to change it. HTC tech support claimed they had nothing to do with the battery manufacturing so they wont help you.
if you reboot your phone how accurate is it to the actual battery meter showing you the percentage? I am at 6 percent left on my phone in hopes of discharging it and than charging it full to get mine to work

It will still probably jump down about 10% but it will sit there for a LONG time until the system is actually to that percent. My recommendation is dont reboot the phone if you want to keep accurate %. The rebooted value I dont believe indicates actual battery life remaining. There is a communication problem between the phone and the battery - HTC confirmed this is going to be patched (on the phone with them last night).
So I've noticed that the phone doesn't charge above approximately 73% when fully turned off. I'm using the standard Google charger for the phone. It also charges normally when the phone is turned on. See screenshot...
My refurbished Pixel also does not show only around 65% charge after being plugged in for the whole night.
But then when I use it, it sort of freezes at a specific battery percentage, so it is on for example 30% for two hours, before it goes further down. See the attached picture.
So at least in my case, the phone is fully charged when turned off and plugged in, but somehow the percentage count of the phone does not recognize it. Maybe it's more or less the same in your case?
I too am having battery issues since updating to the latest October Android 10. I have bootloader unlocked and rooted with latest magisk Canary build.
I can charge to 100% but it then tends to stick at a certain% for a while and then the battery dies at 15-20%. I've tried battery calibration but it doesn't seem to help
I've had a dose of the same lately, had a couple of days where my charge has reached 42% for the entire day? Still charges fine but from a 100% charge I will lose at least 13% - 16% charge in a few hours on idle with nothing showing as draining heavy in battery manager. If I run it down to 18% or less and try and use the camera it will shutdown and if I can get it to reboot it's on 1%. I've come to the conclusion its the battery (could be wrong) purely as it's acting exactly the same way as my nexus 6p did when it's battery started to fail.
Can anyone suggest what is happening here please with Mate9?
My phone has a new battery for last 6 months after original battery started swelling and expanding the phone case. New battery works like original except very occasionally, maybe once a month, the battery runs down faster than normal. It might normally last 36 hours whereas once in a while it would run down in 12 hours - last time the usage attributed high power consumption by Huawei Health app, but I don't know if this was culprit before. HOWEVER, when I plug in charger the phone doesn't charge but continues to run down. If I turn it off it doesn't charge but continues to run down. Then if I wait a few hours with it turned off it then acts normally and recharges 100% in 90 minutes in the turned off state for a full 36hrs++ usage when powered on again.
So what is wrong? Just and old phone needs replacing?
Hello. I just noticed something weird on my TCL 10L phone. When the phone reaches 100%, it displays fully charged on my lockscreen. Though, unlocking the phone I see the phone is still charging. I see the battery bar being green with a charging bolt. It takes around 15-30 minutes until it says charged (and the bolt removed). Is this normal? I do not remember the phone doing this when I bought it around 5 months ago.
Changes in charging and especially sudden loss of capacity can indicate a battery failure.
Check for cover swelling/bulging, battery swelling is a failure, replace asap if so.
A failure this early is rare but Li's can fail at any time in their life.
Inspect jack and port for contamination. Use a known good charger and cable. Try cycling the battery until the phone shutdown then charge to 100%, repeat... to calibrate battery indicator.
Minimum start charging temp is 72F
Best start temperature is 82-90F
Never attempt to charge a Li below 40F
Keep battery temperature below about 101F when charging.
Do not use phone while charging as it will skew the charging curve.
Thanks for the reply. There is no battery loss. I can play games on this device, browse, and check apps and drain the battery in the same period I did since I got it. I actually charged it to 100% since went to sleep. 9 hours later the device was still at 100%. 1.5 hour of playing a game after that and the battery was down to 84%. The issue is really weird. I am thinking a battery calibration may help. I do not know.
P.S. I am currently using Android 10 and I do not want to switch to Android 11.
I wouldn't worry about it.
It's best not to charge to 100%.or below 30%.
Lu's like frequent midrange power cycling (40-65%).
As for 11, no way that crapware is getting on my phones....

Did you personally experience this on any device? This is the first time I saw something like this. According to some articles the phone may display wrong battery stats. So I was thinking calibration would be a solution to this issue.
