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,

Update to Radio 115 or 114

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.

Kaiser's battery drain so fast after dropped

After being dropped while charging, the battery of my Kaiser just use almost a day (previously from 2 to 3 days).
I installed acbPowerMeter to measure power consumption and it shows an unbelievable value: 4294967mA
When plugged into the charger, the power consumption back to normal (I think), between 90-275mA. I wonder if Kaiser power circuit is broken or not.
Who have experience please give me an advice. Thanks!

Hi, if you've dropped your device you should check the connections to the batery. Try pulling out the batery, check if the "pins" are aligned, check if you batery isn't cracked.
Other thing that might have happened is that if you install new software it may drain you batery, i had the same problem after flashing and was only solved after getting a fix from the chef.

Thank you for reply me!
I checked the battery connectors and tried different battery (borrowed from my friend), so the result is still the same. I did not install any software before and then.

Hello, I have same issue with battery drain. I don;t know if it was droped because I just bought it used and battery is draining in one day. I tried another tool called Mobadi, and it saying that my Kaiser using 90-200mA. how about you?

90 -200mA is normal draw. Your battery is losing capacity over years of use, thats normal.

...normal draw during screen on and active use...
with these older devices, there are too many tiny things that can go wrong which cause weirdness.
1. Testing with a known good battery (NEW does not equal 'known to be good'-- I had two new batteries which would not even take a charge, followed by a new NON OEM battery with a low capacity cell inside! they use some undersized cells probably for pricing reasons... sort of like sticking an AA battery in a C cell shell. Not really sure what you can do in that case...)
2. Hard reset and see if the problem persists before doing any more troubleshooting.

Battery readings going completely wild

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
Sent from my SM-N910C using XDA-Developers mobile app

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.

Random turn off

Hi,
I have a Note 4 SM-N910C variant that is almost 3 years old.
Starting from 5 months ago the battery level would start dropping fast from 35% to 0% in like 2-3min after which the phone would turn off. If i took out the battery and insert it again, start the phone again it would show around 30% battery level. After a while it would start doing the same fast drops in battery level and so on.
I got a new battery, not OEM and now it doesnst do what i was facing above but it randomly turns off no matter if im doing something with heavy or no load on the device.
The turning off usually happens after the device goes bellow 50% battery level.
How can i test if all the components are ok other than the battery which seems to be faulty in my opinion.
I did order a new original OEM battery but it will take time to get to me.
I want to find out if the rest of the components are functioning without faults so i can decide whether i should get a new phone or not.
Please assist.

New battery

I know its not the same behavior, I have 2 note's. Mine is only a couple of months old while the one from my wife is build in 05/15. Her phone when we just received it would refuse to charge above 96%. Sure the phone would say 100% but as soon as you unplugged the charger it would drop straight to 96%. It did this on 3 different batteries, exactly the same behavior. All these batteries are OEM. When you plug it in it would go rapidly to 100%..
Anyway, I wiped the cache on that phone and since this it charges normally.
Been comparing the battery drain and both phones are using around 6 to 8% per night while on stby with wifi on.
Just try this, it may help you!

Thanks for the replies.
I did try wiping the cache and even did a factory reset.
I rooted the phone 2 days ago to try and recalibrate the battery but i didn't help.
I think the situation isn't degrading cause from today the phone is constantly hot and the cpu is running at around 48 celsius with 7-8% load.
I'll see what happens when the new battery arrives, maybe the phone is heating up cause of this maybe not. It's even eating the battery from 100% to 0 in 2h with no real load on the phone.
Do you guys think a benchmark program will force it to thermal shutdown if this is the issue.
I'm still trying to find out if only the battery is faulty or i have a dying phone.

To me you have 2 problems...a faulty battery and a (new) software problem on your phone.
Constant being warm with a cpu load tells me something on your phone is running all the time consuming your battery and causing your phone to heat up, unless it behaved the same before the factory reset and rooting?
You are rooted so try Wakelock detector for root to see which app (if any) is causing your phone to behave like this.

I will try wakelock to do its thing during the time i sleep. But if that doesnt help ill try a custom rom. Im not gonna factory restore and go back to stock rom. Gonna move away from that and see what happens.

[Q] Battery problem - suddenly turn off

It’s been a while that I have a strange problem with my batteries. I used two different batteries, both original, charged with the original charger support for the second battery (sell in bundle with it).
It’s almost two months that my phone started to turn off suddenly when the battery level is around the 30%, with both of them. I thought it was a problem related to the batteries age, since I’m using them in the last 2 years.
I tried anyway to contain the problem. As first option, I did a battery calibration. To do this I needed to discharge all the juice from batteries. I noticed that the residual 30% that I saw before the phone turn off wasn’t a fake value: it was real.
When I turn on the phone in recovery, the battery level is exactly the same that I have when phone turn off itself. Moreover, to reach 0% of battery level I have to wait a while and I can keep the screen on (always in recovery) for about an hour. On the other hand, if I try to restart the system, the phone turns off just after the Samsung logo of starts a non-sense bootloop.
Considering what I ‘ve written above, I think that my problem it’s not an hardware problem.
Does anyone have similar problems? Do you have any suggestion to avoid it?
As supplementary information, I’m running the last Italian official firmware with TWRP and root.

same problem
I am note 4 owner for 1 week now
it is an used phone (rebuy)
original rom 6.0.1 newest updates
on delivery the batterie was on 0%
first time use it shutdown at 35%
without warning
now after multiple charging and calibration
it shutdown at 20%
in 2 days I will get new Batterie and I will check again.
maybe batterie is old

Similar issue in the last week or so with my N4. Original replacement battery, 10 month old, turning off with no warning on reaching between 20-15 % charge mostly if i try to use the camera. I've put back the original battery and seems fine for now. Ordered another battery, Anker this time, just in case

Yeah Samsung carefully crafted these batteries so that they won't work any more after six months of usage of something. Mine is nine months old, the phone itself, brand new, and mine turns off at various battery percentages, sometimes its 5, sometimes its 12, I have stopped caring and I charge whenever I get a chance.

Conclusion Faulty Battery Only
Any battery poerventage is mainly determined with help of its volatage. As battery discharges this voltage also reduces. As battery grow older, we is gradually unable to handle the load as it used to when new one. Also battery life is determined by its charging and discharging cycles. It was all about basic. Now talking about note 4, being andriod fone and requres lot of battery so we usually charge it for 2 times depending on use.
The same problem was faced by me as well for note 4 at 30% it used to reboot all of sudden and thereafter bool loop (in actuality it is not as battery deoesnt handle load and it again starts to boot so no home screen). Replaced the battery with original one a month ago and now issue till date and fone lasts below 5 to 10% with 4G on and doing browsing.
So it is concluded for sure that battery problem.

Weird thing last night i experienced the same issue! And my phone is only 8 month old, i think this issue it's related to Samsung updates.. my phone did shut down in exactly 30% and started to go in bootloop i removed the battery and put it back and still the same i was about to factory reset my device for god sake ? luckily i did connect my charger before i factory reset my phone i gave it one last try and it did boot normally.
So i am not really sure what is going on.. no more updates for me unless it's a major changes

Happened to me too. I think it's the battery, I tried several batteries, some cause sudden power off some doesn't.

I'm upping my thread after two months to say that I solved my battery problem changing them. I bought a new one from Samsung official store and now I'm able to do more than 4 hours of SOT and charge phone once in two days (Red Dragon Note 7 porting). Before to change, I was not able to use any Sammy ROMs, due to several reboots and disgraceful battery life.
I don't know if the battery is the guilty for everyone's problems, but I really suggest to try to change it. Just, be sure to buy an original one, because there are a lot of genuine clones, especially on e-commerce sites.
For what regards the problem itself, I think that the cause could be the use of a different charger (Samsung, but for an earphone), coupled with the extra battery kit. Unfortunately the original adaptive fast charger stopped to work a month after the phone arrived and I didn't bother about it.
So, I also suggest to use only the original cables to charge the device.
I hope that this testimony will help someone with the same problem and, at same time, I also hope that Samsung will consider to use again removable batteries to give people the opportunity to do what I did.
