Battery Problem [getting worse] - Samsung Galaxy S7 Questions and Answers

Hi all, I own a Galaxy S7 and it works perfectly fine until recently.
The battery would went to 0% from 5% (after the critical warning) all of a sudden, and it happened again when it was at 15% today (also after a battery warning).
Is it because of a bad battery? Should I get my phone replaced?
Attached is a screenshot of the battery usage, as you can see it dropped from somewhere near 15% to 0% (it shut down itself all of a sudden, and wouldn't turn on unless I charged it, and it started from 0%).
Any help would be appreciated and I am sorry for my poor english as I am not from a native-english speaking country.

hi mate
All this happen after an app or OTA installation?
first thing is to find out what is going on , try an app like BBS to monitor all process and see if one is going wild.....
Factory reset is always a good option to reset all apps and re install them one by one and monitor how the battery behaves after each installation
Backup first !!

Battery drain... funny problem

Hi All,
Got this funny problem since I have flashed TNT WM6.1.
My mobile battery shows some funny traits.
1. It can suddenly go off (even if the bar is at 87% or 63% or 30% or anything of that sort)
2. Once it goes off, it gets into a loopback of restarting the device, goes upto the screen where WM6.1 logo appears and restarts again.
3. The only way I can then get it restarted is to get it to plug to a powersource.
4. When I plugin it shows within 5 min that the battery is fully charged.
5. I use audio manager a lot and its like every 30 seconds 1% of battery is gone.
Have search through the forum but haven't found anything like this.
Anyone has face a similar problem and found any solution?
Any help will be much appreciated.
I am on SPL/IPL 3.08.
Time for a new battery....
I ran across the same problem. It turned out that the terminals on the battery were seriously worn down so much that the battery couldn't hold a charge to safe it's life let alone mine!!!! I went to a battery store and replaced the muthaf^$#a!!!!!
Go grab a new battery and you'll be electric sliding again in no time!!!!
Thanks Trej3k. Much appreciate your response.
Yeah
Had the same issue.
Replaced the battery ... and now everything is fine.
Now I don't expect 5 days without recharge but at least 2 days.
Along with the new battery I bought an battery charger so now I can use two batteries.
The nice thing is that the old battery is lasting at least as the new one, Maybe because of the charging more regularly and not so frequently and because both batteries never go in usage when they are hot of charge.
Try your thing

I had the same problem pretty soon after I flashed my ROM for the first time. I would charge to 100% and then browse the Internet or take a call, and the device would reset within a couple of minutes b/c it would think it was out of power. The timing may have been a coincidence; I don't know. I bought an extended battery and everything works fine now.

I had the exact same problem right after flashing to wm6. I really wonder if it's a coincidence.
I ordered a new battery today because I have exactly the same problem. I also apeared after flashing WM6.1 a while ago an became worse with time. Since my battery is 3 years old, it could also just be a battery at its end of life...

S6 battery dump (rapid drain) problem

Ok, so over the past couple of weeks I've had more than a few occasions where my battery will drain very rapidly.
It happened again tonight, and I watched the battery % indicator drop from 48 to 15 over the course of about 15-20 mins. Once it hit 15 it then shut down completely, apparently completely drained, as I put it back on charge and it restarted charging from 0%.
I got the 5.1.1 ota update (Stock EE UK rom) last week, but it's been no help.
I've attached a screenshot of the battery usage. On screen time has been about 3 hrs today.
Anyone any ideas? Would it be worth rooting, or is it a dud battery?
Also, using the Nova launcher BTW.
Well. I haven't that problem but got a very similar.one was charging.
My phone had battery dead and the plugged the fast charge when it was off. The charging image displayed the battery in 8% after a few minutes as normal, but when I powered the device the battery indicated that was charge at 56%. I was shocked and immediately thought that battery had a problem. Then I used the device hard to get the battery drained but was normally going down. Then restarted device and the battery indicated 18%, much closer to the real charge.
Anyway, I had this issue on my old SGS3 and then remembered that I had to delete cache from recovery. Once I made it the battery started to work normally.
The fact is that I'm on G920I with the Indian sotck version of 5.1.1 and I never had rooted or flashed my SGS6 afraid of tripping Knox. So I recommend that you. Delete cache from recovery and check battery. If the problem persists definitely your device is bad.
You may have a defective battery. Return your S6 back to Samsung for battery warranty replacement.

Samsung Galaxy S7 battery issue

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.

galaxy j7 battery problem

i think my phone has some serious problems and i'm wondering if it's the battery dying or a short circuit
when i plug it on a charger while of it shows a normal charging image but how it switches from one animation to the other so i can see the status of battery percent it's like a short on the screen happened
it chargers to 100 but when i switch it on it shows mybe 95 but never 100 and if i connect it to a charger to get to 100 it only decreases
it gets warm now days which did not happen and it like drains 50% overnight which is obviously not normal. these two days the battery life is like 4 hours with internet wich with j7's battery it should not happen. if i switch it off and then on again i loose like 20% of battery and if that is all i had i get 0% and the phone doesnt switch on. the phone never had contact with water . it's been 4 days since this started and it happened all of sudden like today my phone stays up to two days at most and i just woke up it barely finishes a day without data and with power saving mode
i'm sure it's not about background apps or any activities because i hard reset it already and i don't have any app. and it's not about wifi or sync or poor network i tried all that. i did everything it didnt help. i could buy a new battery but i'm scared it might be a short because i don't think a battery can just die in one night like this.
can anyone help me with this or it's nothing serious and i have to change the battery

Battery calibration error?

As of maybe a couple of months, my phone shuts off almost immediately after getting to 20% it turns off and when plugged starts charging from 16% or so. Any idea what may be causing this and how to fix it?
I have the same issue mate. It happened twice for me. Was using Snapchat and the battery drained down to 19% and then it suddenly showed 0% and the phone shut down. And then after I charged it for a bit, it showed around 20%
I have same problem here, guess factory reset might helps.
Same issue on my friend's Honor 8.
Mine turns off at random percentages. Sometimes it happens at 20%, 10% and most recently 67%. I'm wondering if changing the battery would fix the issue
same issue here disappeared for like 2 months and it happened today
This suddenly happened to me today, I was using Snapchat and I took a pic, was writing a caption to send to my friends and all of a sudden it dropped to 0% and shut off, even though it was already at low battery I know It still had enough life for me to be able to send the snap and listen to music. What sucks is that I didn't look at the battery percentage before It turned off but when I turned it back on it was at 13%, even though when I tried turning it on from before it kept telling me 0% and shutting off repeatedly
i noticed that when i plugged in the charger and checked the recents all the apps opened were showing up.....looks like its doing soft reboot but cant complete the reboot......smh!!!
Same problem here

Rooted stock
I realize that it happens when it's really cold outside. It happened to me a second time today when I was outside in the cold, so I guess the phone turns off to prevent anything from happening internally, because it shut off at around 50% of battery and when I turned it back on it wasn't 0% like it had told me
I'm switching out the battery today I'll let you guys know if it fixes the issue
No root till now fully stock.
Well replacing the battery fixed the issue. I also deleted battery stats once it was charged to 100%
Same issue here. My device goes from 20% to 1% in about 2 seconds. And then when i charge the phone, it shows charging from 19%. It happens all the time.
Hi, had same but my first time died when I was flying drone with it, it was at 17% of bat. I was so nervous that I lose my drone that I forgot to check what was the problem with bat. Now when I was trying to film my daughter skiing after 2min outside of my pocket it turned off although bat. was at 78% and tem. outside was -3*C. Yesterday I've send it on warranty, I let you know what they say (if anything). Mine H8 is stock no root.
Wander is there any app than can check number of cycles of battery, this way I will know for sure if Service replaced battery or only told that it was replaced

Did you guys need root to delete the battery stats?

Did the service center fix the issue?
Yes, they replaced battery, screen and frame, actually they only left old back panel and MB. Screen was replaced because of dead pixels (but I didn't saw any before). After a year, I think I have same issue with battery again but this time no warranty anymore ;(
