Battery readings going completely wild - Galaxy Note 4 Q&A, Help & Troubleshooting

So recently my phone (unrooted unmodded N910C) battery is being extremely weird. When I try to charge my phone, it sometimes doesn't go beyond around 70-90% but if I take out the battery and put it back in, it shows 100%. It sometimes also shuts off on its own at around 40% and when I plug in a charger, it shows sometimes 0% and sometimes 40% (but if I turn it on, it still says 0%). I've tried a lot of things, including discharging completely and recharging to 100% (powered off), factory reset, clearing cache, and quick starting battery and nothing seems to work. Does anyone have similar problems and has anyone found a solution to this?

The problem is the battery ... the catode pin inside battery is not working properly. The motherboard of the phone it just reading the voltage and temperature of the battery. Your percentage shown on status bar is based on what current intensity is received from battery. So just replace the battery... esxuse my poor english

Are you sure it's the battery? I took it out and everything looks normal, including the pins. Also, battery apps said that my battery health was good or should I not trust them at all? I just don't want to buy an extra battery if the problem is not with the battery.

I meant the catode pin inside battery not outside. It's your call if you buy a battery or not. I just writed here how the proces work because i have fixed lot of motherboard i knowing about this i have explained to you. Cheers

i have the same problem too and i tested every things and now i am really tire , i dont think thats problem was the battery , can anybody help me plz?

Had similar problem yes new battery at the samsung store the assistant said many note 4 batteries selling I got the last one. Maybe we got a bad batch or its deliberate. Maybe we could do a survey how many people have had to buy a new battery

I also posted a similar problem. In my case the problem is more alarming, because it's happening in two different batteries, one of them is rather new and fresh. It seems that it started out of the blue, I did not make any major change in the phone.
I am still investigating the issue, I'll be back with more observations.

Just an update on my situation: I bought a new battery and now the battery readings seem to be fine.

I had the same problem as you OP. The problem was definitely the battery for me at least. Bought a new one just the other week and now everything is working perfectly

If the affected battery is under warranty get it replaced for free. Or if the problem does not get solved after cross checking many possibilities. Just buy a new battery. Simple. Good luck.

Battery Bad Meter

Hi
I have brought a new battery it is a high power version 3200ma and when it is in the pda it allways reads 100 % on the battery meter does not go up or down so dont really know if its charged charging or empty any ideas.
the same here
no ideas
No solutions yet
my 3800mAh from expansys operates correctly with the battery meter.
Same problem, its not a bad battery meter, its a ****ty third party battery. E-bay, right? i bought two of them from different people, and my batteries kept playing up for no reason. I marked one to keep track of which one was which and it turns out each have different problems. One stays at 100% for ages, then drops gradually to 78%, gives me all the error messages, and after a soft reset lasts till ~50%, and the other has different issues. It must be something to do with the chip on the battery. There isn't really a solution in my mind, just make sure you know what each battery does
ahh i should have read this earlier .did any one bought battery from mr buybits off ebay? if so do's it has any problems ?

Another Jasjar Battery Drain Problem!

Hi all, i have developed this weird problem in my jasjar and i'm sure it's some settings that need to be changed somewhere and not the battery itself. When i first got the jasjar, it gave me a good 48 hours battery backup on standard use but i lost my charger and started using usb to charge it. it's since then that my jasjar drains the battery in less than 12 hours. i have tried replacing 3 batteries but to no better effect. I remember reading something about the Li ion polymer batteries having the memory effect or something and how to reset that in the bootloader mode. if you guys could help me figure it out and fix the problem, i'd appreciate it! here's the details of my rom.
R:1.13.00
G:42.47.p8
D 2.01.06 wwe
the rom is the wm6 from jwright.
(nb: i had the same problem with my shipped wm5 rom and i thought upgrading it would help but it didnt apparently).
How long do i need to use the battery to check the drain thingy. the reseller tells me to use it for 2 weeks before judging it. i'm screwed with having no battery life to this otherwise beauty of a device! if i could get any help, it would be much appreciated. thanks in advance. (josh).
Had the same problem, been happening all week, the phone would just switch of even though it registered over 80% charge. no i am happy again because i read on the forum that you need to totally discharge the battery occationally for it to get to a full charge, it appears that there is some sort of memory effect where the battery thinks it is nearly discharged, try it, i am sure you will find that it workes.

I too has a similar problem but this method did not solved my prob as my jasjar switches off by itself at 40%.
I had a similar problem a couple of weeks ago as a charge would last less than 24 hours when I used to be able to last 2-3 days.
Soon sorted it when I found that the Jasjar had decided to disable the automatic switch off, now a charge is back to lasting 2-3 days.

Had my MDA PRO for 1.5 years, and never had this problem. Battery lasted for 2-4 days on average, although now I have a 3200mAH battery it lasts for well over a week on a single charge
Lithium ION and Lithium ION Polymer (the HTC Universal uses the latter) do not suffer from any "memory effect". The only battery type that does to any significant extent is Nickel Cadmium, which is rarely used these days.
It's also impossible (well, almost) to completely discharge Lithium ION Polymer batteries - internal circuitry in the battery shuts down the cells when the charge gets too low, at up to 10% charge. This is because a completely discharged L.I.P. battery becomes unstable, broken (unable to be recharged), and runs the risk of explosion or leaking in this state. So don't attempt to drain those batteries completely dry folks - it's dangerous! Letting them run down naturally in your Universal should be safe though because of the cut-out mentioned above.
Maybe the Uni just has a large batch of bad batteries? You should also check what apps you have running on it all the time, and how often you use bluetooth and wi-fi - these two REALLY drain the battery if you keep them on all the time... Also try MemMaid, this is great at cleaning up your notifications queue, which is where lots of apps leave old and obsolete entries clogging it up.
I have the same problem. I do not know where the charger is, so I am always using the USB while syncing. I also tried 2 batteries, but they both last about 12 - 14 hours. Maybe it is caused by WM6.
I did not quite get this solution:
"Soon sorted it when I found that the Jasjar had decided to disable the automatic switch off, now a charge is back to lasting 2-3 days.

What is the solution?

btw aj had the same prob. appeared after 6mnth. i bought new battery. btw here is several threads with same prob. try 2 look for solutions there(imho its only one-new batt.)
I feel like I'm walking on eggs...I bought my Jasjar used on eBay just over a year ago, still the original battery. I almost never use the 110v charger, always a USB conection with my Mac, often recharging at 55-75%. I just intentionally ran down my battery to 18% (got warnings to recharge), and recharge via USB/Mac again. It took me almost 4 days to get to 18%, and Bluetooth is constantly on for ready use with my earpiece.
Curious: are the problems with original or replacement batteries? Cheers,

It's worth taking into consideration that when flashing, you really need to have a full battery. There are reports of batteries starting this kind of behaviour after user has flashed with drained battery, then causes battery charge issues until next reflash.
IMHO even if u charge with a full charged battery still u get a prob so i think its a common issue with the jasjar and its power managment software itself by default as lot of people with diffrent ROMs are complaining about it.
no changes...
well, folks, i tried all these gimmicks but not to any definite changes ... i guess i need to consult the service center guys at last...i didn't want to do that but i guess i need to. i'm sure it's not my battery as i've replaced 3 of them...i dont kno what else to do!!! thanks for ur posts tho as i get to try diff things to check if ma battery is doing ok...keep postin...thanks...

how 2 discharge a battery >>>>>
problem with battery?
I have the same problem, it firs appear on original battery when charge was 40-50% so I have bought the same battery model (1620mAh). But it doesn't help. Now I,m using the 3200mAh battery and it doesn't help as well. The thing is that XDA switch off it self always on deferent charge level (sometimes is on 20%, 45% ar 80%...so is very difficult predict when it happen again). And one more thing...when it switch-off and I try to switch-on back, I can't (keep switching off), only slolution is put on charger!!!
I have downloaded the service manual (I think called "confidential") and it mentioned that it could be a problem with main board (so its HW problem). So can anybody tell me is a problem with bat or MB? (replacing the MB is fcjfdj$#ing expansive). Thanx.
well if your XDA does not switch on until you start charging it that's a clear indication that your battery is empty. I have the same with my faulty battery. Replaced it by a working one and it's fixed. Something is definately messed up with the charging circuit or the batteries though. They are not supposed to die so easily.

The first time I flashed the PDA I ruined my battery. This time I thought I'd be smart and I put in the old battery while flashing. After flashing I put back the new battery and now that one is broken too! It wasn't even in the PDA when I flashed it. How bizarre is that?
I have to admit I did not fully charge that new battery before flashing, but I figured it would be safe since it wasn;t in while flashing. The battery worked fine the day before I flashed my phone (got the "charge now or save your work" message), but after the flashing and putting it in, it just crashes at around 30% or 40%. The usual battery misery.
Maybe I should try fully charging it and then flashing again. Trouble would be how to get it fully charged though. I always felt charging cuts off early on the "broken" batteries (pull the charge plug and stick it back and it charges for a while again).
I managed to restore my battery to good health by completely discharging it in bootloader mode.
First I completely charged it. When the led went green I pulled the shcarge cable and connected it back again. After doing this a few times it doesn't stay orange so long and then I stopped and left the cable disconnected.
I reset the phone (on full battery) and then I set the unit to boatloader and waited for it to completely discharge. I reset the phone again (on empty battery) and low and behold my trusty "charge now or lose data" warning came back.
BTW I reset the PDA hoping maybe it would store the power levels. I remember that trick from my Palm days where sometimes you had to reset a PDA on full battery to calibrate it.
I charged it back to full capacity and started using the phone as normal. When the battery was empty I got no crash but a friendly warning telling me my battery was going low. Phew.
Will try the same with my other troubled battery over the weekend.
I have the same Issue.But , I think it's about Rom.
and I'm try a lot of ROM version ,only one Version canbe use more than 3 day.
I can't find any reason ,.
discharge in bootloader ,I do it ,But battiery is same time for used.

[Q] Battery or charging circuit problem

The scenario is this. I charge it every night. The orange light does work and it will show 100% in the morning. It will then shut down at random times and when restarted say the battery is low. I can plug it in again and reset it and it will show from 0 to 100%. Once I take it off the charger it may run all day and deplete the battery or it may die suddenly and tell me it's got a low battery again.
Should I consider the phone dead or does it sound like a faulty battery. It is the original battery and is 2 years old.
Marksm,
I think could be caused by:
1st: some hidden app wich consume a lot of energy that is placed on your phone or
2nd: a phone virus made to produce that behavior or
3rd:a battery control software issue.
For that, I'd advise you to:
1st: verify the programs and process that are running on your phone, seacrh for unknow ones and see on the internet what they do so you can remove the unwanted ones;
2nd: install one or more of the mobile antiviruses (one at each time) that are avaliabe on the internet and perform a full verification of your PDA;
3st: put a new ROM on the Blackstone; but first read how to do it well, if you don't know how, and be sure to be aware about all issues and risks that this action may bring.
Wishing you a good luck!
Stay in peace!

I have exactly the same problem. I restored the original ROM and SPL and nothing has changed.have you tried another battery? Is like the battery controller is broke. The phone is under warranty but the battery is not covered, so I would know if send it to HTC or to buy a new battery!
Similar issues reported in a post above. A new battery seems to have fixed it but needs more time to tell. I will probably order a new battery too.

Hardware/Battery Issue/Loss advanced question

Hi guys,
My had brother hard a problem with his phone regarding his battery life. He claimed it drained too quick. So he bought a new phone.
After I had "accidendatlly" destroyed the eMMC of my nexus 4 (See this thread) he gave me the phone and told me if I could fix it that I can buy it for a sharp price form him.
I've replaced the battery with a newly bought one online and got the phone out of hibernation mode by connecting it with USB cable and doing the volume down + power button trick.
I've noticed some issues regarding the battery:
- The first time I rebooted it battery life went from 96% to 84%. This was when doing a factory reset (from the menu in android 4.2.2). This has occured once.
- Last night the phone was fully charged so I hooked it off the charger and turned it off. This morning I turn it on and I notice the battery is at 66%. Literally 1/3 of the battery life was lost when the phone was turned off.
Obviously, (I think) there's a loss inside the hardware of some kind. There's one piece of history attached to the phone.
My brother had it one month and dropped it on the floor and his screen was cracked. He then let the screen be replaced by a repair center. They did replace the screen and locked the screws from the battery with some kind of glue (i think) because it was very hard to loosen them.
My questions:
- What could have caused this? Can it be by something done by the repair shop (reversible?)
- In which part of the hardware is this (loss) most likely to occur? Or one can't know this?
- Would it be sensefull to disassemble the phone and replace the screen with the screen from my broken phone (the one with the broken eMMC chip), or is there 0% chance on success by doing this swap?
- Any suggetions on how to tackle this problem or is it just something I'll need to accept. (which is hard to accept, )
Kind regards,
Semi
You should first try to charge it to 100%, then calibrate the battery (there's a little tool in the play store called BatteryCalibration). The percentage values are just approximate. Android knows the amount of mA the battery has when full and constantly checks the current as it drains to calculate the percentage left.
Calibrating the battery basically means deleting these statistic files to allow the system to start from scratch. You may need to do a few discharge/charge cycles until it is somewhat reliable.
If this doesn't help I assume the fault is hardware sided.

Hi thanks for your Swift reply. ive checked the app out and i think it needs root. This phone hasnt been rooted yet so ill Get to it when i get home. Greetings.
I do have the exact same problem (phone was never droped) - see this thread:
http://forum.xda-developers.com/nex...rs-off-charging-battery-t2701353#post57181337
Nexus 4 seems quite vunerable to this though I've not found the cause/solution for this on the web yet.
Exactly the same here: Old battery made a worn-out impression, so bought a new one. Actually tried three different new ones from ebay now, all do the same: They charge up to 4.3V around, and when unplugged drain to 87% in a few minutes, i noticed the voltage going down to 4.0/.1V mostly, too.
The current battery seems ok from battery life, but i want an even distribution of the battery status, no matter the voltages - how can i achieve/fix this?

Extreme battery drain

Hey guys, recently I've been having a TON of battery drain. A while ago someone replaced my screen since the I dropped the phone and the glass broke(stupid me). My friend and I thought that maybe that guy also replaced my battery, without telling me. But what mostly happens: When my phone is on like 50% (sometimes less, sometimes more), it shuts off. When I restart it its at 1%. I added some screenshots off today where it happened again. What could be causing this? And is there anyway I can check if the battery is replaced? Also, the new glass has a few stripes under and above the screen. I don't mind in that much but does anyone know about that aswell?
Thanks in advance.
Well you could first try to reset your battery... There are several methods out there. Just google for it, one popular one involves deleting the batterystats.bin file.
There are also apps that show you the battery health. If it is poor, it is likely that the battery is just damaged or drained.
I used to buy second hand devices, to check the battery I usually read out the charge cycles (how often the battery charged from 0 to 100). However, I don't know how it works for Android these days. But searching for that key word might help you.
