I've recently started having this problem. I charged my wizard overnight, saw the battery was 100%, then as soon as i removed the charger, it drops to around 80%. If i follow this with a soft reset, it drops to 50%. During normal usage the drainage isn't so sudden, but it is still a lot faster than usual. For e.g. a 20 min video would drain 30% of the battery.
My extended rom is clear, I first installed the 2.26 tmob rom, then wrcx1, so I dont think that should be an issue. I've installed the power saving cabs as well. What else could be the problem? I'd really hate to have to switch to another rom just to sort this out...
Forgot to add, this is a recent problem. I used to get excellent battery life, this has just suddenly started happening. I haven't changed my charger or battery.
which BS are you using?
I was using the latest BS release (0263 i think) but have removed it from my today screen and still the problem is persisting...
Battery... that's what driving me crazy now! With WM5, I can use my device almost 2,5 days with lots call/sms and solitaire. Tried 3 WM6 version and couldnot save the O2 life last more than 3 hours (uncontinuosly). Please any one help to solve this.... (
Sounds like either your battery is screwed (they DO go bad after a year or two) OR you've got one seriously ****ed up ROM.
By the way, BatterySpace is known to do this if you use the dynamic overclocking. Somehow something in the ROM or Registry gets trashed, and then the system will peg the CPU at 100%.
This will WASTE the battery like nobody's business! Once this happens the only fix is a HARD RESET - I've not figured out what's getting scrambled, but whatever it is, a reboot doesn't fix it.
Shut off the dynamic overclocking if you're using it and see if the problem goes away.
I just had the same erratic behavior from my battery, it was over a year old. It would charge to 100%, but when off the charger strength would read random levels and drain really fast. I could kill the battery in about 30 minutes of browsing web pages.
A new battery solved it.

OK, thanks!
Now I'm thinking about downgrade to WM5 to check wherther battery died or not, before buy a new one.
I have the same issue on the g3 wizard connected thru tmobile us running the bd3 rom. I have had excellent battery life in the past but in the past 3 days or so the battery status is just inaccurate. The main prob is that when you go connect to the internet 5 min later the device restarts and sometimes it just keeps restarting in a loop. Then sometimes it restarts but battery is at critical, when before it was at 80%.
But i noticed when it gets stuck in the boot loop, just stick it on the charger for a sec and it will start back up fine, but then die after a couple phone calls or so.
I have also cleared the rom thinking it was some battery drain issue that usually happens when you don't flash the original rom before you flash a cooked one. I installed the tmobile original one and then flashed "boring rom for tmobile". That rom works quite well. But the battery is still draining.
I also changed the radio rom from the 2.69 and now went to the 02.25.11 but still the same issue.
I didn't try running straight wm5 and see if it did it their, but the previous poster is trying it so ill see if that worked for him or not.
The next step is to try a new battery but this battery is only like a year old
Believe me when I tell 'ya that Lithium Ion batteries, when they die, do so exactly like this.
Try a new battery.

mine is doing the same thing..
if i start any aplication that requests more procesing, the device keeps rebooting, even if the battery was indicating 100% when i started using it
if i plug the charger when he is rebooting, he comes back to life 80-100% charged..
if i do not use it, and leave him on stand by, the battery lasts for like 2 days without any issues.
Draining in Sudden Bursts! Sounds like it feels good.
well i guess i will just get a new battery and hope that solves the problem since I have tried everything besides just using regular wm5, and someone posted that this is what lithium ion batteries usually do, so I'll give it a shot and report my findings after christmas, lol I hope I get a mda battery for christmas
anyone bought a new battery?
did it worked?
i´m still waiting for mine to arrive
I bought a new battery, but i cant say yet whether its working or not. It seems to work fine at times, and gives the same problem at other times. Not sure what acould be wrong....
Are you using TNT5 ROM? I've flashed two days ago this ROM to give WM6 a second go and my battery vanished like smoke... the battery that used to last for about 4 days, was gone in only half a day :\ I'm back to my ROM!
I'm using TNT5 for a few months now. All of a sudden i had batteryproblems. Tried everything but solved the problem with a fresh battery. Only 9 dollars on Ebay....
And now the phone is running smoothly again (lasts about 2 days)...
still waiting for mines to come should come wednesday, its getting worst and worst i used to be able to use it for at least an hour now only for about 15 min off the charger, when it says its at a 100%
I'm having a different kind of problem, except for the burst that I get after taking off power or after a soft reset, my battery life is exceptional. My last charge lasted about 7 hrs (including ebooks, mp3s, sms, and some phone calls).
I flashed XDA Mobile 6 Release 5 RC1 with .NET CF 3.5! recharging full battery. After flashing It showed low battery warning and when i restarted it, it showed full battery. And one hour later it swiched off. Now i flashed another rom .No problem yet.
I took my Shield Tablet (stock 5.0/rooted) off the charger at around 8 am today starting at 100% (charged while completely off), and at 11am I noticed it was at 49%. I'd only done some mild gaming (Terra Battle), and Comixology reading, so it struck me as a little low, but what confused me more was the battery stats page. Screen shows at 130%, System at 10% and everything else in single digits.
Anyone know what's going on here and how to fix it? I've rebooted and will be watching out for whether it happens again, but would be happy about feedback from anyone who's experienced a similar issue. Thanks in Advance!
Since you are rooted you should use an app like Better Battery Stats to log what is going on.
This way you can identify which app is causing the drain and take measures to prevent it.
Known cause in quite some cases is Facebook after applying the ota to 5.0.
Solution is to remove the facebook app, do a factory reset and install the app fresh from playstore.
Thanks for the reply. I don't and never had the Facebook app installed (shocking, I know ) so that can't be the issue.
I've installed Better Battery Stats so I'll see if I can figure anything out through it...
My guess is that the screen has used 130% of the batteries capacity. If you look at the bottom of the graph it says stats since last full charge. I gave my niece my old first gen nexus 7 with lollipop and a few days later looked at the battery stats. Her screen was listed as 160%. It hadn't been fully charged since I gave it to her. The screen brightness was maxed out and she tends to leave it on the ground with a video playing. The screen obviously uses a lot of power so its not hard to imagine it was over 1.5 times the batteries capacity.
Has anyone noticed their battery getting incredibly worse over time? I bought my S7 on release (non edge). And since then, I've noticed that it doesn't last no where near as long. Today, for example I started my day at 7:00am when the battery was 100%. As of 30 minutes ago, the battery reached critically low (5%). From 7am all I did was watch a few videos, facebook, snapchat and then play music. But all the above for not too long.
I've also noticed that once the phone hits the 15% battery (I know due to the notification), that within minutes the battery can be done to 10% or so, without touching it.
I'm more so tempted just to take it back, unless there's an easy fix OR it's a known issue with the current version.
Thanks!

I've definitely noticed this since rooting. Maybe it has something to do with that? Like a ROM you flashed or what not? I'd like some suggestions here as well.
Thanks!

I haven't rooted the S7, it was the first phone that I've left stock from opening.
What does the battery stats say is using the most mAh?
Facebook app is a known battery hog
Obviously over time, you'll install different things, and slowly the phone will start using more and more power running background apps
A backup and Factory reset will show if there is a hardware / battery issue, or if it's purely from stuff you've installed over time
Also clearing the caches from recovery could help
yeah ive noticed this too. My usage habits havent changed but my battery life is almost half of what it was when i just got the phone.

Cache has been cleared from recovery, and I don't generally install many apps so since I've bought the phone the apps have stayed the same.
Android system is always on top. Unless of course I spend hours on Facebook.
Might have to factory reset. I've used my phone with the same apps and time since I've bought it, and I'm finding I'm charging it 3x as much.
I think it's a root issue - deep sleep.
After S6 Edge Plus, when you root a samsung phone, it won't go in deep sleep. I believe there's a fix for that.
Have you checked the battery usage stats? It gives you the breakdown on what apps are eating up the battery.
I have had my S7 for about a month and battery is about the same.
Just to update this thread for those that may have a similar issue...the other day I couldn't live with the battery life the way it was. The phone used 50% in several hours where I barely used it.
Decided to completely re-flash with stock (was stock before) as opposed to simply wiping all data. A week in, and the phone's battery life is back to the way it was. I went to bed when it was on 100% (as a test) and woke up 7 hours later with the phone on 94%, with wifi, location and bluetooth on.
Not sure what had caused it to use so much battery previously, but it's back to what it should be and that's all that matters.
hi with my s7 exynos i do 3h screen. i think there is a problem. i bought my s7 one week ago. can anyone help me?
Rooting and installing custom kernels when done right should greatly increase the battery life of your device. This is a well known guide here on XDA for improving battery life for our devices.
That being said, Lithium Ion Batteries hold less charge the more cycles they are put through, its a given fact but as you said your device is relatively new and therefore should not be experiencing this kind of problem. The way I see this is there are 3 possibilities which may be causing the said problem...
1) You have rooted the device and done some modification/s. ( which you haven't done )
2) Your battery is being drained by a service ( Like Oculus or VR ) in fact a number of reddit users complained their S7 was overheating and battery was draining really fast for some reason. Check This page out, It might help you.
3) Battery Defect, you must've gotten a "bad" model, if you haven't tripped KNOX you could try bringing your phone to Samsung and see if they would fix or replace it.
Good luck
I think this has to due to them samsung updates. As far as i know samsung been always doing things like this where they made the OS slow as hell after a while so you gonna get a upgrade sooner but a battery should last 2 years minimal without degrading.

i get like 5 hours screen on time and bout 1 day standby time but i have most bloatware disabled with the package disabler. But if i was you i would contact samsung.
This happens with Samsung updates on every Galaxy phone. It's like a curse. It's unavoidable.

May i ask if the people with these problems use the fast charge? I hearing many bad things bout this so i switched it off and must say the normal charge isn't that slow and if it can keep the battery good for longer then we all should use this.
I turned fast charge off about a week after I got the phone, was making the phone and charger pretty hot for the sake of about 5-10 mins quicker charge
Pointless really, unless you are desperate, only have a few mins spare and need as much power as possible in that short time, and if that's the case, enable it for that one time
Restrict background data on all but the most important apps (phone, text, email), dave power all but the most important apps. Battery life is fine

Hi
All of a sudden my battery started draining rapidly. See the attached screenshots for ref. I thought maybe it was a software bug since it started happening 2 days ago. I tried booting into the safe mode and the fast drain didn't stop. I also did hard reset with same result. At this point I'm thinking about getting new battery. Just wanna see if xda community has any tips if maybe I've missed something. It's just strange that this sudden degradation happened overnight.
Obviously, that draining is not normal.
In the upper left corner there is a warning that some app is running in background.
When you did the hard reset also you did a restore from some backup? Is the device warm/hot?
Sometimes it shows carrier utility or people apps running in the background. I restored from Google backup (forgot to mention in the OP). Device isn't hot at all.
i stared clean with LeeDroid ROM (had original Sprint ROM on) after wiping the data and the fast battery drain remains. at this point i'm going to replace the batter since it's not a software issue.
I'd definitely say your battery has shat itself. I'd also try something like gsam or battery info in *#*#4636#*#* to see the health of your battery. I'd be interested to know if it reports it as "good" health
It's strange but the standby seems to be better now whereas it was going fast before. Thought maybe it 'fixed' itself, however during a phone call (4min) I lost %3. That's definitely not normal 4636 is not showing any battery info. Can't find anything in gsam showing health status of the battery. Is it in pro?
If the battery drains fast during calls can be due to poor/weak network reception (the modem tries to maintain the best quality and scans the network over and over).
3 sot with 50% (or little more) battery left is a good value, in my opinion.
Oh, when recoveries are made due to some problem is better to not restore from backups. In that backup can be the app or setting that is causing the problem.
Anyway, with the last google play services (14.7.99) I also have noticed a bit more drain during standby.
Sounds like you need to replace it

I have about the same issue. The battery is draining too fast and it's very noticeable when idle, even when idle in safe mode + airplane mode it loose 20% during an 7 to 8h night. I tried all htc nougat and oreo official and unofficial roms and nothing fixed the problem.
I also used the htc diagnostic tool to determine whether my battery is "good" or not and..... according to the diagnostic tool it is "good". Notice that according to diagnostic tool the battery is defective only if it goes from 100 to less than 75% during the test. Mine goes from 100 to 93 during the test which consists in showing a kind of dark grey screen at full brightness during 1 hour.
Even with a battery rated as good I decided to sent my device for repair because it was not good.
I received the device back and it has not been repaired because it passes the diagnosric tool test. test.
So i'll replace the battery myself as soon as i'll receive my new battery.
I suggest you to run the diagnostic tool test and if you get a decrease from 100 to less than 75, they should repair it under warranty, if not, suggest you to replace the battery yourself or pay somebody to do it for you.

I already ordered the battery and will do the replacement myself if the wait times are similar to those of screen replacements. Plus everything points to a bad battery so another test with official app is pointless. Sounds like we both will be doing the swap ourselves.
So I put new battery in and the drain seems slower than before and the charging is not erratic (jumping). When I was removing back cover the black layer came off so I figured it'd be good time to try clear cover mod . I like the look but unsure if anything will interfere with the radios and such due to the missing protection.
Hello all, so the original battery on my Google pixel, almost 3 years old, went to complete hell. It turns off in about a minute once unplugged, despite 100% battery life. So I went and replaced it with two Amazon bought batteries. The first one (definitely not OEM) had the same issue but my pixel would at least last about 10 minutes of regular use, unplugged, before shutting down. So I thought it might be the battery but the second one has the exact same issue. The second one at least looked like OEM with the exterior but since it came from Amazon, it's not 100% certain.
The problem is that the phone charges very fast, like 100% in less than 15 minutes and then discharges 10-20% in just a few minutes. If I last below 70% that would be out of the ordinary.
Is it possible that it's not a battery issue but maybe a different issue? A friendly person on another forum suggested that my core or graphics IC is overheating, attempting to throttle down; and then just shutting down when it looses the battle. Which makes absolute sense since the phone mostly shuts down when I'm playing games on my phone and usually turns off just under 80%.
I also found out that a recent google play store version was found to be the culprit for the extensive battery loss for other folks. Could this also be reason?
Are there any tests I could do to further determine the actual cause?
Thank you.
Two ideas:
- Deactivate Play Store app in Settings -> Apps & Notifications -> All -> Play Store -> Deactivate
- To rule out a damaged third party app as a cause for the battery drain (which actually is quite unlikely in your case), you can reboot into safe mode. For that, long-press the power button and then long-press 'shut down', confirm with OK. At the reboot, all non-system apps are freezed. Then you can check if the battery behaves differently.
Did you try charging your phone for about two hours longer, even if it says it is already at 100%? Maybe just the battery percentage measurement system is somehow damaged.
But you already tried that I guess. So maybe somebody else got another tip for you.
do you try flashing stock image? maybe the battery cache is in trouble
Similar to OP, my Pixel XL had started to have some odd issues beginning almost a year ago. It got REALLY bad in just the last six weeks or so when it would shut down at relatively respectable battery percentages (something like 23% - 57%, randomly).

Thanks for these ideas, BenjyTec.
When I deactivated ("Disabled" in my settings), there was no change in behavior. In fact, I had forgot I did that until giving things about a week and had forgotten when the phone behaved the same way, LOL (I just now re-enabled it).
I also tried the Safe Mode (which I had not previously known about - thanks!), and the phone still died out pretty quickly from a "full" charge.

I had also done this several times. The really odd thing is many times I will have it on the charger all night or for several hours, and when I take it off it is only at a very low percentage - from 1% to 16%. !!! Of course more often than not it does get to a higher percentage.

Thanks, gonzakennyn - I have not done a "stock" image, but have factory reset the phone, with no joy. This was actually one of the things I did months ago even before it got really bad, because I wondered if maybe the battery cache or something at the kernel level had deeper issues.
Hopefully the OP might have had better luck or found something...
All these complaints sound like power supply issues.
Use the phone while it's in the charger, and there's no overheating/throttling/shutdown, right?

Unfortunately, I did not find a solution. After replacing the battery twice I pretty much resigned to my fate. I'm going to hold out until Pixel 4 comes out.
Once fully charged, I could use my phone for browsing or watching videos for about an hour before I get to around 30-40%. Then I could leave it unplugged all night and wake up to my battery at 1%. It actually stays that way for a bit.
However, if I use my phone to play any games, I could only use it unplugged for about 10 minutes. My phone will power down without fail at 80% or below only when I play games. Weird thing is, whenever I power it back up, my phone will be 1% but despite that it could last quite a while.
As post-mortem mentioned, I could use my phone while charging without issues so maybe it is a power supply issue, in which case, I have no idea what I could do.
When it's not plugged in to a charger, the only power supply is the battery. Hence, I feel that even your "new" battery is not new.
So a little update all. I updated my phone to the latest Android 10 patch and the battery life has gotten significantly better. It's still not enough to last all day but it can last probably 6-8 hours with minimal use. If I use it constantly, it might last two hours.
I am no longer tethered to my charger when playing games, which is really good news and all the prior issues with the phone shutting down ~80% is gone.
Perhaps the previous Android patches contained faulty code?
I would do fresh install and see if problem resolves. Fresh install fixes all sorts of software issues.
So my battery woes aren't as bad as yours but I did get to the point where I had the battery replaced. I went to uBreakiFix and I have no idea what battery they put in but the bottom line is a brand new battery didn't help much. I got a little better battery life but not as much as I had hoped. I'm assuming that it's either due to the apps I have installed and my usage or the phone is getting old and something is drawing a little more power than it used to. I have not gone to the trouble of factory resetting to see if that would help yet.

Factory resets didn't help my old issue. Updating to the latest Android os helped immensely. As stated above I no longer have the initial issues. I estimate I now have about 70-80% capacity, which is not bad at all considering I bought my battery through Amazon for around $20.
I thought if you got your battery replaced at ubreakifix, then they are obligated to fix your issue or refund you your money.
