I've been struggling with significant battery problems on my OG Pixel running android 10 - fast battery drain. I just need it to last a few more months until the Pixel 5 comes out, but at this point it drains so fast that it's not reliable. Here is what I've done:
1. Factory reset phone. Didn't seem to make a difference
2. Had a new OEM battery installed by ubreakifix. Still the same problem.
3. Tried calibrating the new battery using the technique of draining the battery completely, charging while off, and then restarting multiple times and charging up to 100% each time. The problem was that after each reboot, the battery percentage would start quite low - maybe 60 or 70 percent. It seemed like an endless loop, never rebooting close to 100%.
Ultimately, it it seems that the calibration hasn't worked. I still get rapid battery drain and the phone will often shutoff at random percentages (20, 30, 50 percent). Also, every time I reboot the phone, the new battery percentage is quite low.
Basically, the impression I get is that the phone just isn't accurately reading the battery charge even after recalibration.
I'm out of ideas, but really just need a few more months out of this phone. Any suggestions on next steps to keep this Pixel going for a while longer?

i got a new non official battery for my atrix its 1800mah...
it charges to 100% but drops to 5% in a matter of hours of light browsing and a few games...the thing is it stays @ 5% for a long time, my battery was on 15 hours and it was @ 5% for about 12 hours
ive tried to calibrate it, but im not sure if it does it right, i downloaded a battery widget that says i have not calibrated it yet...this is not my first android as ive had plenty but this is the first phone that the battery has acted like this
also i actually have got 2 of those batterys but 1 doesnt catch charge i put it on the phone and the charge screens show 5% and charging but then stops charging after a few minutes and doesnt have enough juice to turn the phone on
Try this:

Instead of the calibration app suggested in the link I just used CWM to clear battery stats, and *#*#4636#*#* to check if the battery is at full capacity.
im not rooted currently, so ill try the steps except for the jug6ernaut
thanks
Just so you know, the jug6ernaut files are actually what fixes a known battery jump issue with GB. So even if you successfully recalibrate your battery it will most likely still jump around whenever you reboot your phone. For example, you may reboot at 90%, and when it restarts all of a sudden it's showing 100%.
Hi,
I have been facing these two weird issues:
1. Sudden drop in battery percentage: I have found that this occurs only when i reboot my phone (not every time though). So when the phone restarts, the battery is down by 20-30% or sometimes even more. And its not a one time issue. I have seen it happen at least 3-4 times in the last 5 months.
2. Sometimes when I am not charging the phone, the battery % keeps increasing slowly. This has been happening lately since the time I have rooted and flashed my phone. 2-3 occurrences that i know. I don't recall seeing this when I was on stock. Just this morning I plugged my phone off the charger at 52% and I left for work. And right now at this moment when I am writing this, the phone is at 58% charge!!
Just FYI.. I calibrate the battery every time I flash a new ROM.
Thanks,
Sam

I think that Entropy can answer this better but I'll still give a try.
[Q] Why these sudden battery level drops after reboot?
[A] The sudden battery drops is a known 'issue'. It's not a bug, it's the way the fuel gauges are designed for i777.
[Q] How to avoid these sudden battery level drops?
[A] Try not to reboot while it's on battery if the battery level is <50%. In that case, if you need to, make sure that the phone is plugged in for charging and then do the reboot. That should prevent those random battery level drops.
[Q] Will using battery calibration apps help?
[A] No, the way the i777 fuel gauges are designed, there is no need of battery calibration apps. The best way to get accurate battery level readings is to allow the battery to go through full 100%->0% battery discharge cycles for atleast 2-3 times. After each full discharge remove the battery, keep it out for a minute or two and reinsert, recharge the phone.
PS: The weird battery charges that violate E=MC^2 law might have to do with your battery not having been through proper discharge cycles (and thus not having been properly calibrated) after flashing a new ROM.
@Mod These questions are asked many times, how about adding them to FAQs (not sure if that will help though )
@Entropy Please review this post.
Pretty close.
Calibration does nothing on our device - the fuel gauge is designed so that it will always converge towards truth instead of diverging. Also, the "wipe battery stats" method of "calibration" has been proven to do NOTHING on ANY device whatsoever - https://plus.google.com/105051985738280261832/posts/FV3LVtdVxPT - The "charge battery to full" and "discharge/recharge" battery are valid tactics on some devices, but NOT any Galaxy S or S II device (maybe the ****rocket and T989, but not the I9100 or I777.) - There's a slight chance this may change with ICS on the I9100/I777 but not likely.
The advantage of this is that it never needs funky calibration cycles other than "just wait"
The disadvantage is that the gauge will get thrown off in a few limited corner cases - and the "two" issues described are one widely documented one. The gauge gets confused and falseley reports low by heavily battery load immediately following a reset, and takes a few hours to converge back to normality (during which the estimate creeps upward, because it was lower than reality initially).
And yeah this should probably be in the FAQ. I'll work on submitting it this weekend.
Thanks guys..
So looks like the sudden battery drop issue can only be prevented but not fixed!

It's pretty much the characteristics of putting a battery under load and using voltage to dictate battery level. when you draw a lot of current from a battery you'll usually see the voltage level drop, more so as the battery is discharged. Booting up the phone consumes quite a bit of power, substantially more than the device at idle. So upon start up the device reads the voltage level to dictate battery level. Since the device is under a relatively high power draw, it sees a lower voltage than would be at idle. It in return thinks the battery is lower than it actually is, or would read under idle load. the battery level will actually creep back up slowly because it will read a higher voltage, than it did upon start up.
The only way i could think of to get a more accurate reading would be to delay the initial voltage reading/recording upon start up, or to use the last voltage reading to help dictate the battery level. But i have no idea if that's even possible, or if it would conflict with some sort of other operation.
I just don't get it!!!!!!!
I was playing multiplayer in bombsquad today morning wid my friend .My battery was @ 86% at that time
suddenly my battery came down to 15% then in the other moment it went to0% and mt phone got shut down. I plugged my phone in charge through the power bank and rebooted it and I saw my phone was @52 % I started using my phone and it again suddenly sut down this time without even a battery low message
it's been happening regularly wid my phone since then.
What could be the reason? And what can I do to make it right?

This is the wrong forum. Even though the thread is about a problem similar to yours, we don't know anything about your phone.
If you have a removable battery, you might try purchasing a new battery, but that's just a guess.
The forums for you phone are here.
I have a battery reading issue on my Motorola RAZR. Whenever I use a ROM with one percent battery mod, two things happen:
a) It stops charging at 95-96 % (says "full") Not really an issue, if I leave it longer it eventually goes to 100.
b) Dramatic 10 percent(ish) drop. One second it'll be on 27% and then it'll drop to say, 19. It only does this once per charge, and I don't think it's ever at the same level when it does it.
Why does this happen? Is it common? Web search had no answers.
And please don't tell me to calibrate my battery. Not only is that a debunked myth, but I've tried it several times (through an app, and manually through recovery) and it hasn't worked.
Responses are appreciated
Anyone?

Strange battery readings are not unusual after flashing a new rom. I've seen sudden big drops. I've also seen increases in my battery percentage. Eventually after several charging/discharging cycles you should get more accurate battery readings and you shouldn't see such strange behavior.
After my stock battery started dying and not holding the charge anymore I bought two new aftermarket batteries (2300mAh) everything went fantastic for some time, then from one day to the other the battery I use daily started draining crazy (even 2% at time) I tried a lot of roms with no luck. Bad battery you say, here is the weird fact, the other battery which used maximum 4-5 times at month keeping it at half-charge, has the EXACT same drain that the other has. Is it possibile that something in the phone has gone nuts and is indicating wrong values? I also ran a full charge-discharge cycle preventing the low battery shutdown through xposed, and it shutdown some minutes after hitting 0%, at full charge indicates 4.300mV is it correct, isn't it?
Also using the *#0228# code (I can't recall now if it's correct) the charge level drops a lot like 30-50% and I noticed that the phone later stays at that % for quite a bit and also the heat from the battery draining stops and the phone stays very cool also while gaming, until it starts draining again
No one?
You can look at the simple battery-statistics in setting to find abnormal consumption by an app.
Otherwise buy a battery from Samsung's e-store: I bought several 'original' batteries (not for S3) from Amazon and mentioned too early wear after 1/2 year.
Replacement batteries are a waste of money. I had 2. 1 bloated and the other dies in a few minutes. Upgraded my phone instead.
I wish I stole my HTC M9.
Greetings. The past month I've been getting wrong battery readings from my redmi 5(rosy, miui global 11.0.2 stable, android 8.1.0). It no longer charges to 100%, regardless if it's turned on or off, unless I unplug and replug the charger in which case it jumps immediately to 100%. There are massive percentage drops when idling( 20% drop in less than an hour), and the battery will drop all the way to 2% within 24hours. The battery life itself is no issue. I get consistently about 6-7 hours of screentime, and about 2 hours of that screentime the battery is stuck at 2%. I use the voltage readings from gsam monitor to know when the phone needs to charge, (3300mah battery, 4.3 max charge,3.45V minimum).
Attempting to repair the problem I've tried the following:
1) Allowed the phone to completely drain and shut down, left it to charge. No good. Stopped at 88%. I've attempted this multiple times to no effect.
2)Took the battery off the board and replugged it.
3) Bought a new battery altogether. Even replaced the usb board and the flex cable just to be sure.
4)Swapped the charger with one from a Redmi Note 5.
5) Rooted the phone, installed gsam battery monitor. Although I discovered various issues,the battery consumption is still negligible. Assuming I can trust the readings, 70% of battery life goes to the screen. 0ne thing worth noting however is the Android system process is constantly using the significant motion detector. I traced it back it the Google play services, but it doesn't allow me ,even with root access to turn off its use of sensors.
6) Deleted the batterystats.bin file from the system folder.
7) Enabled the battery saving feature and disabled synchronization.
8) Reset smartphone to factory settings.
9) Wiped data and cache from recovery.
10)Flashed a Pixel Experience custom rom.
11)Installed accubattery. It calculated a smaller battery capacity. However all the metrics and statistics were thrown out of whack as soon as the battery started freefalling from 40% to 2%(in idle).
12)Charged the phone from recovery mode(Orangefox). Still stuck at 87-88%.
The battery doesn't drain when the phone is turned off, but it still won't charge to 100% unless I replug the charger.
Also I forgot to mention but the phone is strictly used in airplane mode as secondary device so you can rule out cell standby drain from poor signal reception.
I'm thinking of flashing back the original rom but what are the odds of this being a rom related issue?
I'm currently testing it's full idle drain time. I won't use the device for at least 24 hours or wait until it's discharged completely.
Has anyone else encountered a similar issue? Thank you for your time.
