I have a lot of trouble with the battery on my S7. Shortly after updating to LOS 18.1, it started behaving very strangely. The battery degradation happened over a couple of weeks, so it rapidly got worse.
At the beginning it shut down at anywhere between 15 and 20 percent, most of the time with the 15% warning. It got worse over time, then at some point it switched to being stuck at 80+ percent for almost the whole day, draining very little battery and then it just went black in the evening, like if the battery was pulled out.
I started slow charging the battery, which made things a bit better again. Now the percentage seems to be somewhat accurate again, but battery is draining so fast, I have to charge it twice a day to keep it running. It even drains battery while off, like yesterday I turned it off at 35% and this morning I couldn't even turn it on. Sometimes it also jumps from 100% to 60% after a reboot.
I made a backup and tried resetting the system, which didn't work, same behaviour. I could try to go back to stock, but as it also drains battery while off, I'm not too confident that it will actually make a difference.
As I have another disassembled S7 still in my repair drawer, I could try to change the battery, but my glass is a bit shattered at the bottom of the touch screen, so I'm afraid I'll completely break it this way.
I don't think there is much I can actually do, but I wanted to ask you people for any advice.
Edit: I have successfully transplanted the battery from my other S7 and it works great again. No battery problems at all, so the culprit was a faulty battery.

I'm running virtuous Inquisition 4.0, I've cleared the battery stats a couple of times and no matter what I do when I get down to like 40 percent, the phone crashes and then when it reboots I'm at 4 percent. Sometimes it just does it if I reboot. I can't figure it out. Its really bugging me. Anything I can to to fix this?
Bump? I've been trying to calibrate the battery like I always have since Donut. Has it changed in ICS?
Turn off Power-saving mode in settings and try
Where is the power saver in this rom? I can't find it. I've also noticed the battery draining unusually quickly from screen use. I just went from 54 to 30% from 10 minutes of use. Its been on 12 hours now and I'm assuming that's an inaccurate reading but still disconcerting.
What about the classic backup, wipe and flash technique? It's worth a shot if you haven't already.
Inquisition doesn't have power saving enabled, so that isn't the cause.
Barring a corrupt ROM or firmware, as suggested above do a superwipe and reflash both first, your graph looks like a failure in the battery.
Does it get hot, or has it ever been heat damaged? I'd suggest replacing the battery, if the wipe doesn't help.
Wiping battery stats doesn't actually do anything, unfortunately. Battery readings come from the battery itself. I've noticed mine's been pretty bad lately, 15% then if I reboot it's back up to 40%. 10 minutes later, 20%.
The best you can do is charge the battery all the way, discharge it all the way, charge it back up, and hope for the best.
I don't think its ever been hot enough to get heat damaged. I mean I suppose that could be the cause. My phone hasn't been through a full.power cycle in awhile so I will try to completely charge and discharge it for the rest of this week and I'll monitor the voltage readings. Its been a bit more stable today but still not lasting as long as it has been in the past. If the charges and discharges don't fix it I will reflash the rom. Still doesn't explain why like every other morning my phone will say 80 percent or something after being plugged in all night but after a power cycle it reports 100 percent. Could that also be a symptom of a bad battery? I can probably have T-Mobile replace it. Or maybe I'll buy an expanded capacity one. First I want to try to fix this one though. I'll report back. Thanks for the help guys
This is quite ridiculous. It was at 7 percent for like 6 hours today. I never know how much battery I have left. It's not like I'm getting bad battery life because I've been on for 14 hours today with heavy use but the readings are so inaccurate.
I'm going to do a full wipe, redownload everything, reflash firmware, radio, and the rom and then once I get everything set up again, if it's still doing it I will go get a new battery, probably one of those Anker 1900mAh ones that someone told me about on the virtuous rom thread. I'm not sure if it's coincidence or not that it started happening when I updated the ROM but other people aren't having the issue (except for one or two) so I don't think it's a ROM issue, probably battery hardware.
This is what VI with the Anker battery should look like:
Damn, that's impressive. What's up with that spike halfway through though? I think I'll just buy a new battery, even if this battery isn't broken, just because my god, 22 hours with 6 hours of screen on is incredible. I don't normally have more than 2 hours of screen time in a day and my battery will only last 16 hours
The spike is where the phone was reset, the battery percentage always jumps up 10%-15% on a reboot then goes back down in a few minutes. Also, the screen on time was closer to 7hrs
I would caution that I'm getting excellent mobile signal for 98% of the day, your results will probably be lower with your signal issues - have you tried the new radio driver from Tmobile?
I thought that this was an isolated case but I just had this as well. I've got 25% then I installed something via adb and need to restart. After reboot, the meter reads 45%. Absurd really.
My signal issues are not phone related, its just where I go to school. I did install the T-Mobile radio and have had much better 3g coverage and signal where I thought it was a complete dead zone. Most of the time I just turn off data and sync during school to save battery. After I did 3 complete drains and charges I have noticed that its been more consistent in reading. Still not lasting quite as long but its not stair stepping anymore in the graph. It is a little bit but not as bad as before. I'm still thinking about getting that anker battery anyway. I'm still only getting like 16 hours with 1 to 2 hours of screen usage which I would like to extend. I have a car charger so when it does die when I'm out its not the end of the world but its still irritating.
So I've concluded its a bad battery. Its started doing it again, much worse now. It randomly just loses power several times a day, as if I took the battery out but I didn't. I also.downloaded a detailed battery graph app, I took a picture of my voltage chart throughout today and its all over the place. I'll call to get a replacement tomorrow and then I might also get the anker battery. I'm getting sick of the phone just going black in the middle of a conversation or something rather. Other sensation owners have run into this problem.also.
have you guys all updated to the lastest firmware out and newest version of the rom?
No, I'm planning on flashing that tonight though. Hopefully it just turns out to be a kernel issue and it resolves when I update. That voltage graph appalled me.
when i first start using VI i had about 8-10 hour battery life, i looked around in rom manager, saw some cm9 roms, backed up my VI, and tried the cm9. didnt like it and restored my VI backup. Now my battery life is about 18-20 hours. i dont know what happened there but it helped alot. maybe somebody else with bad battery life should try this and see if it helps.
Well, I dropped my phone, landed on a concrete floor on the corner of the phone, cracked the corner of the screen and the camera lens. But I have insurance, so I'm getting a new phone within a few weeks (it's backordered right now through asurion) and when I get the new one I plan on purchasing an anker battery to solve all of the battery life woes. Asurion offered me an HTC Amaze but it has worse battery life, it's bigger and heavier and not that much better, so I'm sticking with the sensation.
Hey all,
I am currently running CM9 (bhundven's 7-29 herring build) on my Galaxy S 4G, and I am having some problems with random shutdown. This has only been happening for the past few days or so (EDIT: and I have been running CM9 for about three months with no issues). It seems that the phone works perfectly fine until the charge gets to about 60% starting from a full charge, and then the phone randomly shuts off. The phone will not start back up unless I have it plugged into the wall, and the results are a little unpredictable. The first time it happened, I turned it back on and it said the battery was at 1% and charging. Now, after clearing the battery stats, it reboots to 60% battery. It seems to work perfectly fine after that, and yesterday it went all the way down to about 12% before I started charging it again. It just happened again today, and when I turned it back on it said it was at about 60%.
My charging habits are pretty bad for Li-Ion batteries; I tend to let the charge drop all the way to about 10% or 5% before I plug it in and charge it all night, way past what is necessary to get to 100%.
The battery does look a tad swollen, but I might be exaggerating.
I just wanted to know if this is a bad battery with 100% certainty, or could it be a problem with the OS or internal parts, etc. I can easily buy another battery online, and I probably will.
EDIT: Also, I have had some overheating issues with this phone, and I can often smell electrical smoke in the charger port area behind the speaker, which is why I say it might be an internal parts issue.
Thanks everyone,

You need a new battery. I was having the same issue lime 3 months ago; phone was dying at half charge the when it rebooted, battery would be dead. Then when I plugged it in, it would charge in 20 minutes and the repeat the cycle. Put the battery on a table to see if its still flat. If it rocks or spins excessively, its usually an indicator of a bad cell.
Mine JUST started doing the exact same thing last week. Battery is definitely swollen. I replaced it just this evening and I'm in the process of doing a full charge from 0->100 to see how things go. I'm 99.999% sure the battery was dead. Replace yours.
Sorry for the thread necro, but I wanted to thank the OP for asking this question and to the helpful replies. We just had a heat wave here and maybe coincidentally to that, I've been having random shutdown problems. Having looked at this thread and my battery, I can tell that I definitely need to replace that. So thanks, all!
Recently had to replace battery.
Phone was shutting almost immediately after it was disconnected from charger. Charging status when not switched on showed the battery kinda going in reverse. Phone was really odd as it would suggest the battery had 100% charge and then within minutes of disconnecting it was shutting down.
I tried a factory reset/refresh with no change. So I ordered a Genuine replacement battery off flea bay and installed that last Thursday.
Initially phone seemed ok, then wen a bit weird and shut down even though charge was like at 70% or so. Wouldn't restart until plugged in and then in shutdown mode the battery/charging indicator would show 0% and then very quickly showed 70%. Good bit though was it was going up and not down like before.
Fully charged phone overnight. It then seemed really good and lasted until Tuesday with 66% charge still showing. I had not installed FB or Twitter which made a huge difference. Then yesterday it just shutdown again. When plugged in showed 0%, within minutes back to 70% and then charged to 100% in the space of an hour or so.
So I am looking for any advice. Is this just calibration issues that the phone needs to get past. Is it possible the phone has corruption int he ROM.
I appreciate it might be a hardware fault but seems weird that the replacement battery is clearly showing a big improvement suggesting battery was EOL after 2 years use.
TIA

Same problem here i will try to install the oficial rom of xt890 if works i back here if not i don't know what to do
Sooo............issue is still present. Odd thing which I am unable to confirm, due to rnadomness of shutdowns, it that I think it is slowly learning the state of the battery as it originally was shutting down at 70% after 2-3 days on standby. then 66% hen 56%. I did a clear cache partition and a fresh install but still the issue was present.
Clearly the new battery is lasting longer than the old one, just the phone does not seem to know to reduce the charge indicator all the way to 0%.
Anyone any idea why this might be happening.
TIA

Just to add i'm having the same problem.
Symptoms started last week running the stock kitkat rom so i ordered and a fitted a new battery. Initially everything looked good phone said 100% left it over night and noticed it had shut off when i came back to it. Plugged it in to the charger and it said 0% so i charged back to 100%, booted up android and almost immediately it begins discharging rapidly, i would say within 15 minutes its back down to 0%.. I've done this a few times now even left it on charge overnight for 8 hours but its still discharging rapidly everytime. The craziest thing is even if it says 0% in android i can still boot in to recovery and flash away so clearly there is charge in the battery its just android thats out of sync.
What i've tried so far:
Different wall chargers/USB leads/Outlets
Wiped everything in TWRP and flashed CM11
Factory Reset several times
Various battery calibration apps
My next step is going to be trying RSD to flash the stock ROM but beyond that i dont know what to do.
I'm experiencing EXACTLY THE SAME ISSUE with my Razr i, replaced the battery and it's still discharging very fast
Eventually managed to resolve my new battery issue simply by fully charging and discharging several times. It started to hold charge after the 7th charge and after several more discharges it's now up to full capacity.
I bought my phone new when the Galaxy S6 first came out and have not rooted it.
For while now my battery life has been bad but consistent, or I would say acceptable given what is running in the background. With normal usage, including connecting to a bluetooth watch, LTE, and location services on, my phone battery would drop from around 100% starting at 7am to around 70% by noon. On weekends when I'm just at home and have it on Wifi instead and no bluetooth, it takes until around 6pm to drain to 70%. These numbers have been consistent, give or take 5% for over a year.
The problem started recently when I received an OS update. I can't remember if I was already on Android 7.0 before this update and it was just a minor update for something else, or if this updated me to 7.0 from 6.x
The first week after the update the battery was great. With no change in the way I use my phone I was able to go the entire day without recharging. By noon I was still at 85-90% and by around 7pm it showed 60-70%. So I was able to go the entire day without recharging for almost 2 weeks after the update.
The problem started 3 days ago when suddenly the battery is draining like crazy, and it seems like there's something weird with the battery indicator and the way it's charging. Again, nothing has changed in the way I use my phone.
Now, when I use it, the battery will go down by 1% every minute. And even when I don't use it, it will be down to 70% by 8am and 20% by noon. The stranger thing is when I try to charge it.
Before, with normal use, it will take around 1 hour to charge my every night. Also, the indicator showing how much time is remaining is pretty accurate as well. Now, when I charge it, it seems to take a lot longer. The time indicator will sometimes fluctuate. It may show a realistic time like 45mins remaining, then change to 10mins, then back to 45mins. Also, the times seem to be incorrect. For example, before if I'm at 85% it might take another 15-20mins to reach 100%. Now, it will be at 85%, say it will take 40mins, but after 40mins it's still only showing 90%.
I tried restarting my phone normally, and resetting it by pressing the the vol down and power buttons. I also tried other power saving methods like forcing apps to sleep when I'm not using them. But for some reason, the battery is still draining like crazy.
At this point, given what is going on when I charge the battery, I'm wondering if the real problem is the OS update screwed up the way the phone is reading the battery's power and not that the battery is actually being drained. Maybe the battery in fact is still at 70% by noon even though it says 20%.
Sorry for the long post, I just wanted to be as detailed as possible given that this seems to be different from some of the other battery related problems I've read about on the forums.
Any help or insight will be appreciated.
replace the internal battery
Hi everyone,
I have a Leagoo T5c with a more-or-less 3,000 mAh non-removable battery, and for the past few month, battery life has been somewhat erratic. The phone would go from, say, 50% to 10% battery in no time, and I would get the low battery warning, but at other times it could hold at around 45% for a while before really going down for good.
Last night around 8pm my time, the phone went completely dead while the battery indicator in the task bar said I still had about 65% left.
I tried what's described here and there as battery calibration: I left the phone turned off, patiently waited a couple hours (yes, yes, that long) for the battery to reach 100%, then left the phone off for another hour before turning it on.
In a matter of minutes doing nothing more than checking my Twitter TL, the battery went from 100% to around 85%, and was still there went I tucked in for the night, leaving the phone in Airplane mode as I always do at night.
This morning, I turned Airplane mode off and the battery said it still had 82%, which means minimal drain during the night, with all radio off.
Just a few minutes ago, the phone went completely dead after the low battery warning, and the battery held less than 10% charge.
WiFi is off, cellular reception is very good where I live, and anyway, I don't see how LTE could kill 70% of the battery charge in less than half an hour, even if reception was spotty, which it's not.
I plugged the phone into the charger it came with, put it in Airplane mode again, and it went from 10% to 70% just now in less than 30 minutes.
I know for a fact that fast charge isn't supported on this phone, at least not with the OEM charger, plus it has micro-USB, so I doubt the charger can feed it that much juice in so little time.
The charger itself seems to work fine: It never gets hot while charging, not the Leagoo, nor my old iPhone 6, since I use it for both devices.
So, long story short, is there a way or tool to ***really*** know what state that battery is in? I've tried both DevCheck and CPU-Z, and both say that the battery is in good health, and still retains its nominal capacity of more or less 3,000 mAh, but I have my doubts about that.
I think the battery capacity is reduced somewhat, and I need to know by how much.
Any help and input would be much appreciated!
I must add that I flashed a stock ROM on this phone (yeah, again...) a few days ago, so maybe it's the ART cache being replenished that's causing my battery issues, but still, the problem is so inconsistant that I don't know anything anymore...
I had to flash the stock ROM again after trying (again...) to root the device (successful, but doesn't bring anything of value) and finding it barely responsive.
I'm gonna leave the phone as is, ROM-wise, but my battery is still a matter of concern, because it dies on me at the 60-65% mark more often than not, though two days ago I let it drop to 30% without the phone shutting down.
Like I said, it comes and goes. I really need to know if that battery still retains its nominal capacity or not. Any help in that regard would be most welcome...
