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?

sorry for lang. the above understands(i hope)
nastavenia(settings)/napajeni(power)/rozsireni(advanced) tam zaskrtnes co xces a nastavis casy. ak pouzivas phonealarm musis aj tam. pozri si aj podsvirtenie(backlight).
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.

Battery problems

I have the T8585 HD2, recently ive been having troubles with the battery...
I was getting intermittent battery drain for no apparent reason, the back of the phone would get very hot. Searching I found that this had something to do with the SD card not being formatted properly, did this and havent had this same issue since.
Last night I charged the phone while on my PC, was approximately 80%. I wake up this morning and the phone is dead, wont turn on. So i plug it in to charge again and then it starts to do the soft reset loop thing, I just left it go for about 6 or 7 loops and then it seemed to settle. I look at the battery capacity and its 0%.
This explains why it was dead, but why the hell is the battery draining to nothing over night? I did not notice it getting hot last night and it was dead cold this morning. Battery terminals are not bent as some others have suggested as a cause for this.
I really like the HD2 but this battery thing on top of the poor capacity for the this type of phone is really starting to disappoint.
I have not messed with ROMs yet, so its running the following that i got with the phone...
ROM 1.66.707.1 (76641) WWE
Radio 2.06.51.07
Any ideas on this would be helpful!!

Same phone, same software
I have exactly same phone & software, I upgraded rom to this 1. But have had no problems with phone at all. Few soft resets at 1st, but then started deleteing messages, shutting down programs in background, no problems since. Hope you get figured out,,

I'm having the exact same problem. I've had the phone since November and, although the battery doesn't last like it used to, since about 2 days ago the phone has gone haywire!
I haven't installed any new apps or used the phone any differently than usual but, after getting readings of between 15 - 20mA in standby (with Battery Guard) I'm getting on average 490mA now in standby! Crazy! The back of the phone is getting so hot that I'm actually worried that it might do the phone damage and, like the OP, I'll go to bed with a full charge and wake up with the phone so dead that I have to pull the battery before I can start to recharge.
I've removed some of the PDF files and other things that might be causing slowdown etc due to but there is definitely a problem. Does anyone have any ideas of what kind of things I should look for that could be causing this before I contact the insurance guys for a replacement?
Thanks in advance

Im having a similar problem with my HTC raphael with WiMo 6.5 Roms didnt tried if the problem exists in 6.1.

My phone is fine today, was 100% last night, 95% this morning. Im starting to think this is a software issue not hardware due to the randomness....

funny you put it this way.... its actually the other way around.... nevertheless i understand what u mean (off-topic, just couldn't resist ;-) )

when the power usage jumps from 20ma to 490ma and gets very hot the battery has started to fail - don't be surprised their qualty is hit or miss. I'm on the T8585 HD2 (1.66 rom) since November and a few weeks ago the battery would get hot in standby and battery life dropped by half. I popped in a spare battery and problem instantly went away. I've since bought a 1,300 mha battery from Mugen, phone runs great again.

Hi. Had a similar thing with the battery drain, but the last few night I have put the phone on charge as normal and in the morning I have Nealy dropped the phone because of how hot the back was. Any ideas?

Happened again today, fully charged last night, 0% this morning. Very unhappy about this, this is a serious reliability issue that a $700 phone shouldn't have.

I would suggest checking your task managers processes, I had a process - Filesys.exe that was using 98% of my processor for long periods of time and absolutely eating battery life.

Yeah i have installed battlog to see if that will shed any light on the problem...

Did u try hard-resetting ur device?

no, im trying to avoid that at this stage, I want to find the source of the problem.

Had the same issue. Phone worked very well for a few months and then this battery drain + overheating issue started all of a sudden. Tried hard reset, disabled 3g and problem continued. Finally, got my phone replaced with great difficulty and problem solved!
Anyway, check the signal strength. One of the issues could be the phone trying to connect repeatedly when the signal is weak. You can also try to disable data connections to see if that causes the problem (Disable all autoupdates like email, twitter, weather and so on).

[Q] battery immediately drops down after.....

i've read about similar topics, but i think i did not found answers...
i've been aware that x2's battery drains fast. i had lots of bad experience with this problem so i decided to buy a new spare battery. to describe my problem, here is the scenario.
1. i fully charge my new battery
2. i remove my new battery to charge my old battery
3. after my old battery is full, i remove it to use my new battery (which was fully charged 4 hours ago)
4. after turning on the phone, it reports (immediately) BATTERY IS LOW.
5. i scratch my head why, replace it with the old battery instead, turn it on, and reports LOW BATTERY also.
i think this is a phone problem and not a battery problem. what do you think? why do i also encounter same problem with my brand new battery?
please help. thank you...
this is a new problem i encountered after reformatting my phone...

did u try flash to another firmware?
I had similiar problem as u when was using firmware Genenic_sg, flashed to Generic_en then its gone

by trial and error...
by trial and error, i found the solution... (once my main battery runs out of life, i do this steps...)
i let my spare battery stay on the phone for about 10 seconds before turning it on... (something like at least, the phone will recognize the life of the newly inserted battery)...
there are occasional times however, when the battery meter will still say low battery life even if i already had the battery stay before turning it on... so what i do is just turn it off again, remove the battery for few seconds, reinsert it immediatelt, and turn my phone again... and voila! it's finally recognized as 100%.

Note 4 battery, signal and performance problem.

I've been having this strange problem these last few weeks. It happens in different ways.
1. Bellow 25% phone randomly shuts off then when i reboot its 0% battery.
2. Bellow 25% at random % I lose phone signal then the phone starts to lag and capacitive keys don't work then the phone shuts off and when i power it on its at 0%.
3. Phone gets to 15% i plug it in to charge, it doesn't charge but discharges to 0% then shuts off and after that it charges.
If i remove the battery then put it back in after it says 0% it may show 30%/20/15/13/25/30 etc. Sometime it doesn't charge after 87% or 92%. Is it the battery or is something else at fault? Also i can't get more then 2h15m screen time whatever i do and wifi drain is 30% in gsam.

Earlier I had same problemes on my Note 1 and it was because of my battery. Probably your problemes are becuse of your battery too.

Ok I will try a new battery.

I have exactly the same problem!!!!
Like exactly.
However I'd like to add some things:
1. Sometimes the radio signal for mobile starts randomly cutting in and out. It will be full bars, LTE, then nothing, no signal symbol. Then Full bars again, then no signal. In 1 minute revolutions. I am not physically moving during this time.
2. Even at near full battery the phone will get super laggy, stutter, and then finally crash. Once it reboots the battery will be 40% or something. Not super low but lower.
3. The camera seems to have a huge effect as well. I will open the camera, take a picture, and the picture won't save...it will just start to freeze the phone up until I have to pull the battery or it reboots on its own.
I also have a new battery coming in the mail.
However I should note that I am Note 4 910-H using a 910-C variant Custom ROM.
I was worried it was the special Modem I flashed to make the C variant ROM work on my H variant phone that was causing the problem.
Great, but unfortunate to see someone else having this issue too.
Ill post results of the new battery here.
Btw, ive been able to resurrect it from a very low state of charge (3% etc). The only way to do this is to use my fast charger. The fast charger is the only thing that will save it. Even then it takes ages to charge and gets white hot while it does. Its like the fast charger is battling for charge against some unknown force.

Post if you remember when you get your new battery. Hope that fixes it for you.

hi
my note 4 910c become very hot when i use the internet , can i change the modem from lower android like 4.2 to android 6 ? is it work ?

I have exactly the same problem and please if any1 finds any solution just share it here... I tried almost everything but not a new battery.
Battery Calibration By All The Ways, Battery Quick Start via *#0228#, Many Custom ROMs, Many Custom Kernels and Many Stock ROMs and the problem still the same even after I cleanly installed stock 6.0.1 ... Any help please.
Thanks in advance.

New Battery fixed 99% of my problems.
However the phone still randomly freezes and disconnects from cell service.
I think its the modem driver. Freezing might also be due to sd card.

[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.
