I've owned my Note 4 since October 2014 and it's been working solidly since. Last Thursday, out of nowhere, I noticed that from a 14% charge, it suddenly dropped to 4%. I immediately scrambled for a charger and charged it back up to 100%. On Friday, I charged my battery normally again. Charging finished at 11 AM but the drain was abnormally high. My phone was warm to the touch and battery was dead in 4 hours. I was using the phone normally throughout that time, 4g on, location services/bt off, screen off for the most part. I ran OS monitor to see whether any app was locking up the CPU, but, as expected, the main CPU users were Android System and Android OS.
On Saturday, I charged the phone to full again, disconnected around 4 pm. Being that I was home, both wifi and 4g were off. Battery discharged normally, and was only down to 30% on Monday morning.
On Monday, I noticed that battery dropped from 21% straight to 11% straight to 4% in a few seconds. The drain from 4 to 3 to 2% was decent (few minutes of screen on time, on viber), then the phone shut off. I tried to charge the battery with the device powered off, but noticed that the phone simply stopped charging at 80%. I thought that was an abnormality. I tried wiping the system and app caches, but the problem persisted and drain still felt pretty fast. Tuesday night, the phone stopped charging at 91%, staying at the same level for 40 minutes before I gave up and unplugged.
My friend had purchased a fake OEM Note 4 battery and allowed me to try the drain/charge process using his battery to troubleshoot. When I first plugged his battery into my phone, the drain was high at about 1 percent per minute. When I tried to charge the battery, the charge level would not go beyond 90%. I switched on safe mode, but the battery did not charge any further either. I felt by then that something was definitely wrong with my phone. When I restarted the phone to get out of safe mode, though, it suddenly started charging again and hit 100%. With regular use, the fake battery gave me 16 hours of power, which I thought was relatively decent. Alas, when I started charging it again, it stopped charging at 77%. Battery Monitor Widget showed 0 mA flowing into the phone at the time, though the battery indicator in the status bar showed the lightning bolt.
I took out the fake battery and put in my original. It is now charging up normally, but I expect charging to stop before I hit 100%.
If anyone could provide possible explanations for what could be going on and/or other troubleshooting tips to try, I would really appreciate it. A factory reset would be my last recourse.
Thank you very much!
EDIT: My battery went all the way up to 100% this time. But it's the same one that got stuck (at 80% then at 91%) twice in the past.
I'm using two different Samsung chargers and different cords, by the way, and blew out the port with air prior to attempting to charge the fake battery that still stopped at 77%.
I had the same issue, took it to Samsung and they replaced the battery, it has been okay since that

Really? I was ready to write off my battery and just buy a replacement, but what was weird was that even the newish fake battery wouldn't charge fully. That's what made me worried that it's my phone that's the problem.
It'd be great if this could be as simple as a battery problem.

I have this strange issue with the battery calibration.
At first i thought the battery was dying on me. It normally stay active to 35-44% and then the OS would just suddenly report the battery is dead and just turns off.
Then i just boot into TWRP recovery and leave the screen on. And it's able to stay on for another whole hour at maximum screen brightness till it actually dies.
I tried deleting the battery stats in the data folder and letting it drain to 0%. But the OS still thinks it's out of juice around 35-44%...despite the fact that it can stay on for another hour or so in TWRP recovery.
Is there anyway to adjust the capacity of the battery in the OS?
Hi,
When this happened to me (but with 20%), all I did was letting the battery drain and charge it fully while turned off. Don't know if it actually works, but it solved my issue. Give it a try .
Good luck,

Funny, I had just about the opposite problem. It was stuck at 35-45% while charging, or it would only go up about 1% every 20-30 minutes. Sloooowwww. Same solution seemed to fix it--let it drain to shut-down, recharge with power off to 100%. It seems to charge faster with power off, but I haven't done an a-b test to verify.
So I just started getting this after the update to 5.0 on my N10.
Beforehand I never noticed anything, although its been a few months since i have used it till a really low battery.
But I updated to 5.0. Used it for a while, the OS registered like 70% battery and then instantly 0% and it shut down. So I booted to the bootloader to see and it ran just fine for a while. I got bored and booted it back up, immediately shut down.
I plugged it in and booted it up and it was a 0% for a LONG time before it ever registered as actually charging. Then it charged normally until it got to like 25% and then instantly to 100%.
Im hoping its just a calibration thing, I did a factory reset just to be safe but it still did it. I guess the next steps if it still does it after a few cycles is to install a custom recovery and clear stats.
Same thing here
I've got almost the identical issue as the OP. Tablet shuts off without warning around 35-40% batter. When I reboot it says 0% battery and immediatley shuts down. If I boot into recovery mode though it will stay on for 2-3 hours before dying. I tried this and then charged it to full overnight with the device powered down and still today it shutdown again around 40% battery. Tried a battery calibration app before too but nothing has fixed it. This is 4.4.4 stock rooted with xposed. Been happening for about 2-3 weeks now. I'm pretty sure it's got to be software related right?? Anyone find a fix yet?
Just posting to say I'm seeing the exact same thing. It also just started happening since the update to Lollipop. It is shutting down at about 30-40%, then when I turn it back on it is at 0% and will shut down immediately unless it's plugged in. However, like the rest of you also said, in safe mode it'll stay on for a while longer without being plugged in. We really need a way to calibrate the battery somehow. This is a very frustrating problem. No warning at all!
I also have this problem.....this updates are so bugged.....

I have the exact same issue
After a full charge it's saying I only have three hours left on the battery. Battery life is really poor. I'm not sure if the battery is worn out (I've had the tablet since it came out) or if it's from the update.
Same same.
Just had the same start yesterday. Was charged to 100% ran a high intenssity game for an hour (makes my cell phone heat up and kills the battery like mad) but it was NOT affecting the 100% charge. I thought 'thats funny' then it started to go down some then it hit about 55% then BAM. Drops to zero and shuts off.
After that it would not take a charge no matter what I did but then for no particular reason except I was lazy and didnt wanna have to boot it up again after I plugged it in, I left it plugged in and went to take a nap. Came back an hour later and it had charged to 43% after having been at zero for about 20 minutes after I left the room.
Now its stuck at 43% and wont charge any higher. I'm leaving it alone for a few hours to see if it will ever get to 100% then ill run it down to zero then charge it over night turned off to 100%.
Ive been reading this as a battery calibration problem and came across a HUGE variance on the net about what to do about 'that'.
Some say the charge to 100% drop to 0% charge to 100% will calibrate it. Some say thats old Ni-Cad tech and you shouldnt do that with the Lithium Ions. But then others say you should do it with the Nexus 10 because it DOES calibrate the battery and that the tablet software protects the battery from actually going to zero%. (Saves a few percent and shuts off).
But then also someone else said battery calibration only works via a hardware change inside the tablet and that we are actually talking about conditioning. But then someone said conditioning is the max storage and that the 40% to 0% drop is not conditioning and since the charge discharge charge is for conditioning a Ni-Cad it wont help. Around we go.
There was also mention of a samsung PHONE having a problem with a bent usb pin inside the phone. But you had to pop the battery to bend the pin and since you cant do that a on Nexus 10 that doesnt help. (Plus the pin doesnt look bent to me even though about 30 people chimed in saying it helped them. But that was all phones.)
And finally. One website says you have to root the nexus 10 and use a batter calibratino app to calibrate it as option a but option b was some crazy combination of charge to 100 discharge for an hour, charge to 100, discharge for an hour, charge to 100, discharge till your aunts pink underwear falls off or something equally strange.
I'm betting based on you guys os upgrade bug. Just too strange. My 2 year warrenty ran out last month but I hadnt turned it on in six. Maybe thats a good thing. Be stupid to send it in for repair only to find out it was software.
Have to see if after my full cycle charge-discharge-charge it works again.
Prayin for everyone's devices. This sucks.

Suffice it to say I've been seeing this issue as of Android 4.4.4... NONE of the posted recalibration techniques seem to work and as usual, Google non-support is just as useless. As far as I can tell, once in this state it's here to stay... I've had my N10 shut down at 28%, 37%... even as high as 55%, and on re-charge (if I do it turned on) it charges to a point and then shoots straight up to 100%. I've seen the "takes forever to get above 0%" issue too... none of this has happened in any consistent fashion. I had hoped that friggin lollipop would solve this but instead they added a host of OTHER annoying bugs: as in after I restart it, the tablet goes into an optimization mode where it decides it has to re-optimize all 362 apps I have on the wretched thing. There naturally are a few others but they are beyond the mainstream of this evening's symposium....
Same exact thing is happening to me, but I'm on 4.4.
Same issue for me toosince 5.0 (now 5.1.1 BlissPop)
I'm gonna try to see if after my full cycle charge/discharge/charge it will work again...
Same issue for me too, since 5.0
Same issue for me too, since 5.0
to all of you how had had battery charging problems, please advise y you have used the "magenetic" charging cable. (It charge to a 25% higer rate)
I don't know how... I don't know why... After nearly 10 months of this behavior... I recently went through a couple of charge cycles (after it dropped to zero yet again) without letting it drop to zero.. AND NOW IT'S FINE!!!! I have no clue why... None of the stupid on-line non root solutions worked... I think that it's possible for this thing to recover after a random sequence of events which unfortunately cannot quantify because I had pretty much given up.

I am getting the same experience as most of you. Tablet shuts off at around 45% saying there's zero battery left. I assumed it was the battery going bad.
Sent from my Nexus 10 using Tapatalk
Well technically the battery starts going bad (yeah it's not supposed to... but nothing lasts forever) once you start running the discharge/charge cyle over and over again. To be sure my N10 is more than a few years old and while depending on use it can last a few days... it sure doesn't go quite as long as it did between charges as when it was brand-spanking-new. That said, and as said in my more recent post where I thought that the battery was borked, it now will last around two days with heavy use and about three with moderate use... and it now discharges appropriately to near zero warning me to connect the charger without just dying at 30-50 %... and the charge profile is a smooth curve from low to high with no sudden jog to 100% once the charge indication hits 60-65% like it did before. That would *seem* to indicate to me that this is far more a software issue than a battery one, and that purchasing a new battery may "fix" the problem but it won't FIX the problem! i.e. it'll only be a matter of time before it comes back. For all I know, some recent update to some google app took care of it...
After updating from CM11 to stock 5.1.1 I got the same problem. My N10 switch emmidiatly off at 70% battery. It was fine with CM11. Any news on this? Did a battery calibration, but this didn't helped.
I'm also getting this problem for the first time on the Temasek CM rom from 11/05/2015. It seems to have come up only since the 11/05 version.
Still no solution!?
I am having this issue (I think) since I received the update to Lollipop. So, basically it is a bit more than a year now. I was hoping a Marshmallow update would solve it, but: nope!
For installing Marshmallow I also did factory reset and all that stuff: it does not fix the problem...
I recently purchased a used S4 through Swappa from XDA user @disasp6. When the phone arrived, the battery was fully discharged. I let my wife use the phone a couple of days while hers was being repaired, and she experienced the battery running completely down and needing a recharge before the end of the day after being 100% in the morning. I then turned the phone off and put it aside for over a week and when I tried to turn it on, the battery was dead.
I tried a test, charging the battery to 100% and pulling the battery out of the phone for 24 hours. The battery retained it's charge. It did lose just a little bit of charge in a 24 hour period, but I was able to top it off with about 10 minutes of charging. I then left it in the phone for 24 hours with the phone turned off, and at the end of 24 hours the battery was fully discharged.
I've never seen a problem like this. Any phone I have ever owned has retained it's full charge when turned off. The phone is running safestrap with Goldfinger 9.0 XXUGNK4. It seems to be running normally. I haven't seen any issues with the phone firmware or its operation in the limited time I have been using it.
Does anyone have any idea what the cause of this could be, or how to troubleshoot the issue?

I'd say first thing to do is wipe and start from stock. See if that fixes anything.

I flashed back to stock NJ4, rooted and installed Better Battery Stats. I fully charged the phone and left it unplugged over night. After 8 hours of total inactivity, the battery had discharged from 100% to 60%, and Bettery Battery Stats indicated that the phone was in Deep Sleep 100% of the time since unplugged. There were 0% partial wakelocks of any kind. In my thinking, this verifies that the issue is hardware related. Does anyone have any thoughts on this?
I would think idle drain with 100% Deep Sleep should produce somewhere around 0.5% per hour drain, and certainly less than 1%. I'm not familiar with the S IV so I'm not sure the exact number. Can anyone verify this?
Hi, I'm having a weird problem. Last week I replaced my phone's battery. Everything was going fine till the first charge. The battery percentage isn't showing the right value.
After charging the device all night turned off. Battery shows only 79% of charge. If I let the phone charging turned on, it gets to 100%, but short after drops to 85% and then 79%.
First I thought it was a faulty battery. But I'm using it for a week now, and the device holds a day without a charge, I can even get 3 hours of sot.
I tried fully cicles of charge, to see if it's some kind of calibration, but nothing helps.
Any ideas?
Calibration apps or BBS?

Try battery calibration apps or use Better Battery Stats to find what's doing this!!
My Moto x pure edition has picked up a little quirk. It shuts down for no apparent reason under really light use, like scrolling between screens. It always seems to happen right around 30% battery level. After it shuts down, a reboot gets to the logon screen and then it dies. I can do that a couple of times and the same thing happens. If I plug it into a charger it shows zero battery but it will boot and I can log in. The funny thing is after logging in the battery shows 30% remaining on the android battery meter and it works fine without the charger. Seems to discharge normally from this point. This has happened about 5 times in the last couple of weeks. In summary the same thing happens every time: Shuts down at about 30% battery, won't log in without the charger, shows dead battery when charger is plugged in, after logging on the battery shows 30% charge, normal battery life for the remaining 30%. I am thinking something battery related but battery life is not too bad.

Moto x Pure ed

Original battery, about 2.5 years old, battery life is on the decline but still ok.

Any Ideas? This has been a really great phone and I am not quite ready to walk away. I would buy another tomorrow if it was available new.
Thanks any help

That means your battery is getting old and can't provide enough charge for some heavy operations. I would suggest you to get the battery replaced.
I hope not. My experience is the available aftermarket batteries are junk. Not worth the effort. I noticed there was a battery thread, I will take a look at it and see if there is a solid battery available.
Thanks

Mine recently started dying at around 35%, chalking it up to old/depleted battery....plug it in, it powers on showing 35%.....I'm going to ride it out until op6 (possibly pixel xl 3).
This has been happening to me for about a month now, except there is no approximate battery level that it occurs. Most recently, I pulled it off the charger to take a photo, and it just shut down. Held the power button down and it showed the battery at 0%. I then reconnected the power cable, and it showed 95%, so I tried to power it back on and it bootlooped. Tried again and everything was fine. Unplugged it and tried rebooting it and as soon as it was finished, it shut down. Plugged it back in and let it sit powered off for ten minutes, unplugged it and it's been working ever since. But, this will occur at any given time and has made the phone too unreliable for daily use, so I had to go back to my S4 until I can get this figured out. Such a bummer, because I've gotten really used to that big screen and not having to wear 'cheaters'...lol
Ok, seems like it is not a completely unique prob. I have a battery on order. I will see if the swap fixes it. Thanks for the help.
Did you get any solution? Mine started shutting down @ < 50% when I start video app
Use a battery voltage monitoring app like 3C battery monitor and see if the voltage floats around too much, if it does then it's dead.

Hey all
I've noticed something of late with my OP6T. When I charge it to 100% and take it off the charger, it drops ~5% very quickly seemingly without any wakelocks/alarms that cause it. Does anyone else experience this? Is there something I can do about this or is the battery just on it's way out? It's a little strange as the device is only 1yr old. I bought it around 9 Nov.
Here are some of the screens from BBS attached. As you can see it doesn't look out of the ordinary.
Another strange thing is that once it reaches around ~95% then it will start to act as normal, so it takes MUCH longer to go from 95 downwards.
What's going on here?
Other things tried:
- root and run battery calibrate
- factory flash fastboot images
- use custom kernel
All show the same issue so far. This did not happen at all until recently. Any help would be appreciated!
UPDATE: I let the battery drain completely and had the phone self-power off, then powered it up a couple more times until the "Battery too low, charge before use" sign started coming up. Once that happened, I plugged the phone into a slow charger, turned it on and left it to charge. I plugged it out when I went to bed (at 100%) and it seems to be all good now. Woke up 6 hours later with the phone at 98%.
Just in case anyone else is having the issue, give that a try.

Battery percentage is a estimate. Discharging it fully and charging it only makes the estimate a bit more precise. I remember on my old phone that it could drop 40 percent in 15 minutes and when you put the device away in your pocket it could go up about 5 percent.
