Hi everyone,
it seems that battery issues on these devices are quite common, but I wasn't able to find out much about my observations, yet.
I recently got this model cheap in stock condition and decided to revive it. It's running /e/ OS currently, but the displayed battery percentages are extremely erratic.
When fully charged, the battery drains very consistently for 15-20% per day while in idle. However, if rebooted at any time, the phone immediately shows a completely drained battery at 2-4%. It will stay that way until fully charged again and despite the displayed percentages, the battery-app (correctly?) calculates multiple hours of charge remaining.
It does seem like some kind of software issue, since the phone does not turn off or refuse being charged like other users have mentioned and the battery still does supply hours/days of power.
On the other hand, the issue was apparently also present on the stock Android, so it would have to be either firmware- oder hardware-related?
Has anybody experienced something similar with this or any other device and is there anything I can try to fix this?
Or is the battery itself malfunctioning and needs to be replaced? If yes, are there any brands or replacement models to recommend for this phone?

its the battery that needs to be replaced. I had the same issues with my moto z (xt1650), the battery replacement fixed it all. the battery life is now incredibly longer than before and i didn't experienced any suddent drain at reboot.
all that for just 13,99$

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.
Hello, my S2 is now old round year and 8 months.
Recently, when i overload the device will many quick actions, screen flickers and device shuts off.
Also i noticed after 20-30% of battery is gone, its just matter of moments when device will turn off.
About voltage, i noticed, it drops really quickly from like 3900 to 37xxmV in minutes, when capacity goes down maybe 2-3%.
On charger everything is fine
I am planning to get a new battery, but i would just like to confirm a possibility that maybe it isnt an issue about the battery but with fuel gauge chip or some other hardware part?
Can some share some insight?
thank you in advance
Given the age of the battery, logic dictates the battery is on the way out & needs replacing.
I am aware of that, i did torment the phone, am really a power user...
However i just wanted to check if anyone had some similar experiences, or known hardware failures of such kind
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.
Hi everybody
I've got a major battery issue with my three year old Nexus 10.
The battery indicator shows something around 75%, drops to 0 in a split second, switches in energy saving mode (notification and navigation bar are turning red) while it shuts down.
To verify I made an Automate Flow saves the battery charge every second to a text file. Result:
Code:
82,82,82,81,81,81,81,[...],73,73,73,73,0,0,0,0,0 EOF
Okay, it thought to myself, after three years the battery is broken. So I bought a replacement battery (Samsung original) and replaced it - but nothing changed.
To clear all old stats (and running Android 6.0.1) I wiped everything TWRP offered and installed CM13 - but nothing changed.
Now my only guess is, that there's some EPROM (or other memory hardware) that stores battery stats.
Can you, dear forum, help me fixing that issue?
No one?
Has anyone of you guys changed the manta battery, yet?
Same thing after OTA upgrade in D6563
I'm facing the same problem here with my d6563, after the MM OTA update i started to face quick vertical battery drop, but we're not the only ones, some users are reporting this issue in a lot of devices, some of them after update, some others after rooting, some of them just after some apps update, and the thing is that nothing seems to work, some users claim to have solved the issue, but they are just talking to fast, because the problem comes back the same day, they just think taht the battery data is accurate but then the drop accurs, si, i'm starting a new thread listing all the solutions tghat senior members have recomended and failed in order to track this problem to his roots once in for all, it's been happening since kitkat at y has come worse since marshmallow
keep in touch to see what we can figure out about this.
Battery _stats_ issue
I had, ummm, similar issues with my TCL S720 (in less degree) and now with TCL M2U (TCL Meme da 3N M2U AKA Alcatel Flash+) phones.
TCL M2U has 3500mAh battery capacity.
After full charge it discharge normally to ~40%. Behind 40% it is discharged to 1% for a few minutes and shuts off!
If then I charge it again to 100% then it eats about its full capacity (~3500mAh) - checked with Keweisi USB Doctor and shows 100% charge, but discharges to 40% again.
On other firmware there is similar effect but for 30% level or 15% level, it depends on firmware.
I think that the battery is OK but the charge percentage display is wrong.
Another strange thing is when I see the charge level using Ampere app. It shows i.e. 50% battery level and 3.762V voltage on the battery. Then I plug it in charger. For a short time the voltage rises to 3.8V and more but the battery level is lowered to 45%! Also if I charge the phone from discharged state then the battery level is 1% for the long time, then it quickly raise to ~30% and then shows charge process normally (almost linear). The USB Doctor show the charge process smooth almost all time (from stronger current to weaker).
So I join to the 1st post question: where is the battery's _real_ voltage level data?
Hi guys, My device keeps turning off randomly - I haven't found any correlation between battery percentage and turning off nor what app I am using. Happens at 80% as well as at 35%. It just straight turn off, no rebooting etc.
I haven't experienced this behavior while charging though. Also I experienced few times that even when the battery was at like 40 % and phone turns off on the turning off display when there is a sign turning off and litle circle under it, the battery indicator in status bar suddenly turns red as it's empty. Phone turns off and while I plug in the charger it shows correct percentage - e.g. 40 % again.
about phone:
This started cca 2-3 weeks after display change, I thought there might be an issue with connectors badly plugged in or something- checked and everything was ok.
Phone was running on custom ROM Pixel experience (android 10) for over half a year without any issue so I thought there might occur a software issue- I flashed new ROM - Lineage 18.1 (android 11), sadly it didn't solve the issue.
I also did a baterry scan with app Battery Recover 2021 with results: Low 2 %, inactive 3 %, healthy 95 % so the battery is also not an issue.
Only thing I found that is not 100% working is power button, even when I take the back housing off. It's probably worn out and I gotta press it few times from random angle/press with force to do what it's supposed to do.
Can this be the issue? Can this piece of hardware cause random shutting off? Any ideas?
Thanks guys
How old is the battery? It's a prime suspect.
They're cheap enough, throw a new one in.
Replace the power switch if possible as you know it's bad.
Otherwise if it's not gotten wet or dropped and the connectors are all ok, barring the above former causes it's likely a C port pcb or mobo failure.
Do some Google searches for this series of phones to see if others have had similar issues and the cause. Use XDA in the search to find results here.
the battery is original, so 4 years old? It last 1-2 days prior this turning off issue has happened so I think it's capacity is fine, nevertheless I still ordered a new one and I'll give it a try since phone is not turning off while being charged.

Degraded Li's can fail just like that.
A degraded Li is defined as one that has lost 80% or more of its original capacity. That's when they should be replaced to prevent a failure which can damage other components.
A swollen Li is a failure.

thanks man, it was the battery. I replaced it and phone works, no signs of random turning off.
Yeah batterys are usually the thing wrong
