hello,
since 2 days my S7 has a battery crash.
when it is under 15% of battery, it goes to 1% in few minutes and then goes in auto turn off.
i.e. the battery goes from 10% to 5% in 20seconds.
i.e. auto turn off at 13%.
if I try to turn on the battery is at 0%. I only have to charge it.
in the battery stats I see a vertical line under 15%.
Before to do a factory reset, someone knows this issue?
it has 1 year and 4 months of life.
Thank you in advance.

thus might be a problem in your battery itself have you tried taking it to a repair lab and have them replace your battery?
I don't yet called samsung assistance (it is under 2 years warrancy).
Someone told me to calibrate the battery. I have found some guide but I don't know what is the best guide.
Thanks.
it is not only my problem.
Other person have my same issue.

Dont worry, I am almost completely sure it is just a calibration issue, read this xataka post, i think this is the right way to calibrate any battery https://www.xatakamovil.com/varios/como-calibrar-la-bateria-de-un-movil-y-por-que-deberias-hacerlo , it is in spanish but you can translate it. If it doesnt work you better use your warranty, i had a Galaxy Tab S with the same problem and the way to solve it was reconecting the battery(you have to disconnect the battery from the mother board), it is a really simple task, takes 20 secs but since you cant take out the battery because the S7 is unibody, you need to take your phone to Samsung.

Hi guys
I have a galaxy s2 and im having problems with the battery. In the battery usage section the most that takes up the energy from the battery is the display. Even lowering the brightness settings the display is still sky high. Now having flashed it few times the warranty has now gone. Tried different roms and still the display on my galaxy is like 45 to 55 percent. Some say its normal some say its not. Once i fully charge the phone within minutes the battery starts getting drained. Seriously what is wrong with it and what can i do to resolve it. Im past my month that i could send the phone back and samsung obviously will find out its been tampered with ie me flashing it
Is there anything i can do to solve the problem with firmware or am i stuck with a faulty phone and just make the most of it till something else comes along?
Any help or ideas will be appreciated

The battery might be dying. How old is the battery? Li-ion batteries will work for 3 years or so only regardless of whether you used it or not.
The display might be taking up so much battery because that's how you use the phone. ie you don't use much of other battery heavy stuff. Make sure you have a low timeout for battery as well.

The display battery usage will be relative to how much screen on time you have. If you are having problems with how long your battery lasts, download BetterBatteryStats (from my sig) and run it for 24 hours or so then check the wake locks to see if any rogue apps are draining your battery.
If you want to return the phone. You can always flash the stock rom and if you buy a USB jig from ebay, you can reset the counter, so Sammy shouldn't know that you have flashed any roms.
For further tips about your battery, why not look at some of the custom rom threads, like Villainrom. They have very good battery stats and there are plenty of tips in the thread.
Hope this helps
well i have it charging at the moment and i am using cognition rom and the phone is like sleeping as we saying. i quickly went into battery usage and display is like 85 %.
Shall i charge it to the max calibrate it then wipe battery stats and let it drain out till its empty fully charge it and then use it till the end of the week and then post a picture of how it went for you guys to see and you give me your ideas on it?
thanks again i really appreciate your opinions
I have never bothered calibrating my Battstats, but it makes some people feel better.
As I said above, the percentage used by display is relative.
If your phone has been on for 24 hours since charge and your display is 85%, then you have a major problem, as your screen on time must be massive.
However if it is 10 minutes since charge and the display is 85% then that probably equates to a few minutes screen on time.
Once you are charged. Run the phone for as long as possible then post screenshots of the Battery Usage (both pages)

Agreed with killall. Battery stats are relative. Say you have used your for ten minutes after charging and the screen was on for 5 minutes or more, an 85% for display is nothing big.
Like he said, see the overall performance of the battery and its life. Display percentage doesn't make that much of a difference if you use your display a lot. I mean if you don't do much CPU intensive gaming or stay connected to wifi and stuff.
I bought a new battery for my oneplus one from vifocal.com and I think its original battery. The battery seems to be very poor. I use my phone for 1,5 hours from which the screen is on for about 1 hour and the battery has drained down to 50%. Yesterday as my phone went to zero I turned it on in recovery mode to keep the screen on as long as possible to really kill the battery and the screen stayed on for at least 2 hours. How is that possible if the battery indicator shows already 0%. Anyways I believe the battery drops down to 0% even really there is a lot of juice in the battery. Is there anyway to calibrate the battery so it would show the correct percentage and is there anyway to tell how big is the battery really? whether I got a fake one or not. thanks

I've had an opposite issue few times - phone was shutting down while it was show that it still had battery (20% was the worst case). I fixed it by discrharging fully, then letting the phone charge all trough the night. this was the recommendation that I found on OPO forums from someone from their team.
So I've had a S6 since about 2014/15, somewhere around there. I've had problems with battery for a long time, but now, my battery only lasts for about 5-6 hours of sleep, and maybe 45min of use. I factory reset my phone and my problem remains. I then downloaded accubattery and it says that my battery is 86% of stock capacity. Does anyone know what my problem is? Is the battery bad?

Sounds like you definitely need the battery replacing
You could try to calibrate the battery. Basicly tells the Phone when its properly charged and discharged.
Just Google Galaxy S6 battery calibration and the first answer is your manual.
Hello, not sure if this is the right page to request this type of help but here's the deal: the last few days I've been having a sudden crazy battery drain... I cleared the cache, then performed a factory reset and the battery was still draining - around 1.5% per minute with the screen on. Around 1% every 3-4 minutes with the screen off. I read an article about Safe Mode.. and before I got into Safe Mode I had 23% battery... when I got into Safe Mode.. it showed me 62%. I got back into "normal" mode and it still showed 62... now it's currently at 60%. Thought this is weird.. any idea what's going on?
Either bad calibration or a dying battery. Do a full cycle (run it till it's dead then charge it to full before booting). If you still experience problems you should probably get the battery replaced.

Any idea what might have caused the bad calibration?
It seems to be ok for now.. It hasn't discharged yet.. will let it turn off on 0 battery and then charge it full. Thanks.
Calibration can go out if you regularly charge it when it's not empty yet. Modern batteries dont have as many problems with memory, but it's still possible.
Hello!
So my battery drops from 96% to 67% in 30 minutes. Sometimes the phone restart at 60% and the battery drops to 5%.My camera drain the battery instantly to 0%.If my phone is charging the battery acts normaly. My questions is what is the best way to recalibrate the battery?The factory reset will fix this,or updating with huruupdater?
My phone is rooted.
Thank you!
I forgot to say that the phone randomly restart but battery % remains the same and sometimes is charging very slow
Mine was doing the same thing. You will probably need to replace the battery. I bought one on ebay for $8. I followed a youtube tutorial. You will need a hair dryer, phone tools and alot of patience.

you need to purchase a new battery. calibration will not correct it.
