Help! Weird problems on my jasjar

I have a jasjar recently and had problems turning off at 50 percent. It was working fine as long as power odesnt drop below 50 %. Then I bought a desktop charger (made in china) and started charging from there. That's when all this weird problems started.
When I put the fully charged battery inside sometimes it doesn't power on by pressing the power ubtton so I have to reset it to turn on. Sometimes it doesn't turn on with reset so I have to go to bootloader then reset just to turn it on. Sometimes it just won't turn on! If it does turn on sometimes the screen is white! When it does boot properly and go on standby. The lights blink but it won't wake up so I have to reset it. Sometimes while using it, the screen would just turn garbled white.
This don't happen all the time, Im actually typing this post using my jasjar and even if I charge the battery using the phone, it exhibits the same problems once in awhile.
SOLUTION FOUND!!! READ THE LAST THREAD
Any ideas? Could the battery be doing this or is my jasjar messed up? Please help!

I downgraded to wm 5 Helmi ROM and seems to work for now. I was using Helmi's wm6 so I don't know if that attributed to that. Will update.

Still didn't help.. Any ideas? Is my jasjar dying? Please help!

Battery issues
Here and elsewhere are postings which make it apparent that some after-market batteries don't work well with the Jasjar. Some electronic devices are relatively fussy about voltage and amperage levels, and some off-brand batteries are fairly wide of the mark in those regards. Not necessarily on the low side, either.
The problem is not limited just to computers. I had an electronic remote reading thermometer whose display went nuts; the manufacturer asked whether I was using EverReady or Duracell batteries. When I replied no, I was using Ikea batteries, they told me I had to use EverReady or Duracell batteries or I was likely to encounter the problem, and they're right: using those batteries fixed the problem. Not that the Ikea batteries were bad, mind you: their power level (voltage and amperage both) were actually too high, according to the manufacturer, and my VOM tester confirmed their assertion.
Somewhere on this forum is a link to an eBay supplier of batteries which work reliably in the Jasjar. Good hunting! Cheers,

Thanks but I'm using the original battery. So do you think that the desktop charger did something to the battery?

may be it caused by a desktop charger. When i used a chaeger made in chine for my alpine, sometime the screen goes white, or ALL buttons seems die (All button didn't work). The most terrible is that charger make my dive hard reset 2 times (first time i din't realise if it cause by my charger, then i just install all progs but when i charge, it hard reset again).
Even for 5 days after i bought it run well, except the ringtone goes on silent every time i charging.
Now i throw away that thing.

So its the charger!! GRRR...Anyways, even when I'm using the Jasjar to charge, everything is the same. Lockups from standby, white screen..You think I should try another battery? Any ideas?

Weird stuff / battery related?
Hi there,
dont know if anyone is reading this thread coz it is kinda old, but i have the same probs mention as above. I have the orginal bat and charger which came with the device. I also uses a car charger sold from my phone provider.
now after 14 months i have the weirdest things like shutting down randomly when the bat is about 58 thru 50 percent. I can not start the device again coz it stops in the middle of the boot process. It only starts when i connect it to a laptop by usb or to the standalone charger...
I tried differnt roms found here and radio roms but it doesnt help...
my guestion: does any one know if this prob is solved when I buy a new battery? or is it wise to thro out this universel suck device ( I have had so much probs with this device so neglect my tone...)

I bought my Universal (Jasjar), used, almost a year ago and use it daily. To date, I haven't had this problem, but I'm anticipating it. Yeah, I'd say it's almost surely your battery (they don't live forever), just be careful to replace it from a reliable source.
Sorry you don't like the device; I've thoroughly enjoyed mine! Cheers,

Hi,
I guess u r right, batteries will die. So I ordered a new one, I will let you guys know if it helps. I bought the qtek 35H00058-00M battery which is the orginal bat
The thing is, normally will a battery be faster drain so it would become faster 0 or 10 precent, instead this piece randomly shutting down or switches off in the middle of a phone call.
I have a Blue Angel as well, now for more then 2 years, which is charger daily just like mine unversal. The batt of the Blue Angel outruns the uni with bat life. Never had this weird stuff with the ba, like shuttingdown without a warning.
Well I will see if a new bat will fix the trouble, tomorrow my new bat will arrive.
cheers.

I also have the same issue with the 02 Exec. It switches it's self off when the battery reaches below 50%. I have ordered a new battery. Will let you know if this still happens once it arrives.

Well,
I already knew it but now its for sure at my end. HTC and ms together gives u pretty expansive CRAP.
Got my new battery which was carefully chosen because of other rumours of battery problems. I bought exactly the same battery from QTEK as the original.
Yesterday i got the battery, left it alone to get on room temp. this morning switch it with my old battery.
1. First thing what i found strange was that my **** device said it was at 100%
2. after 45 min I had the same bat prob as with my old battery
3. device can not be started on bat power, which would let u think that the bat would be ZERO procent. However turning the device on when on wall power this **** device says that the bat is 100%, but disconnecting it from the wall power it shutdowns right away.
conclusion:
the new battery is worse then the old bat. the only difference between them is the serial number. same type same manufacturer.
I was already think of buying a non HCT / Micro**** mobile device, but today after 14 months of trouble and losing important phone calls I am going to say good bye to this universal crap.
I wise u the best with our device but for me it ends here.

UPDATE:
Used a 3800 mah battery from expansys, made in Taiwan by Dyna and still same problems...not battery related at all...Anybody got a mainboard they can sell me...even a broken miniusb.

Problem and solution found
The Problem is a faulty voltage controller in the mainboard causing Bulverde CPU to hang and give funny colors to the screen
Solution is to disable Cpu scaling of Bulverde by using pocket hack master and setting speed at 312mhz before turning it of or closing the screen. You could always set it at 520 when using it but before turning it off make sure speed is 312. Hopefully this helps others with this problem.

backup battery level has been disappeared!

Hi to all, and thank to moderators to keep this usefull site alive.
My jasjar was working good but nowadays it suddenly goes off and wont return untill the recharger connect. when plugging the recharger the red led turns on for about 30 seconds and then the phone comes on with yellow led turned on, and when I check the battery levels usually shows the main battery 100% has been charged and the backup battery level has been disappeared!
and after completing the charge process the led turns off instead of turning to green.
I have flashed it with the latest arabic rom and cleaned all necessary parts of mainboard with electronic contact cleaner. I have also measured the backup battery power on the board and it shows about 2.5 v that I think its ok. any idea is welcomed.

How old is your device?
Almost everyone experiences similar symptoms after 5-6 months, and then the battery dies. I haven't had the backup battery disappearing though...
If it still has the warranty(which I doubt after flashing a ROM...), you should have the provider change the batteries. If the warranty is still void, they can still order a new battery, but it will cost you a bit.
Good luck!

I appriciate your attention. Unfortunatly the warranty period has been expired, and I have tested 2 other jasjar original batteries (from friends) but still the problem exist.

I appreciate the appreciation.
if that's the case, you might want to take it to a repair shop, because this might mean a problem with the battery control or power routing circuits, and I don't think anyone should meddle with those, except maybe the designers...maybe the guys in the shop can do something, like a new motherboard , battery, or something.
Good luck in getting it up and running again!

CHARGING ISSUE - shouldi be worried?

I bought a second hand HD2, however it arrived with a third-party chinese battery. I contacted the seller who apologised and said that battery was a replacement because the original didn't hold a good charge, and he would send the original through the post. The battery however was fully charged so I flashed all the neccessary files and installed NAND Android (my reason for buying it in the first place), however today - the same day it arrived - I noticed that the orange charge light was going off, usually when the phone screen went off. This necessitated plugging the USB lead back in again, and within sometimes less than a minute the same problem would occur. I have checked the battery prongs, reset the the phone, changed USB settings etc and the problem persists.
Just wondered of I should be worried...I am unable to find an identical problem to this on the forums so I'm assuming it's not a ROM issue. I am currently using the Desire port from DFT.
Would a cheap Chinese battery demonstrate this sort of problem?
The seller says he never had an issue of charging the phone.
My next resort is to flash Windows Mobile back on, but I'm at work and a bit anxious so was hoping for someone with some experience to reassure me!
All USB syncing etc works fine...it is literally just charging that's the issue.

Maybe it's your USB that's faulty. I had a faulty usb that would go on and off sometimes too. However I don't see why the battery would affect the LED light, as the battery has to be connected to the phone for it to stay on, and so the battery can't be losing it's connection with the phone randomly, so it's either your usb cord, or the port.
Word of advice, don't let your phone lose power cuz of the faulty charging. I assume you know that MAGLDR doesn't let you charge the phone while off, so a dead battery in our case, is a dead phone. Happened to me once cuz of my usb, luckily there was still a small amount of charge left after i took the battery out and placed it back in.

It's definitely not the cable as I've used an official HTC charger with it which does exactly the same thing. I've also tried with a Samsung MicroUSB charger from my Galaxy S

Maybe it's the usb port then... That's the worst case scenario because you'd have to get the whole motherboard replaced...
However if in winmo you don't experience the problems, then it was just some software problems, so try a different radio and build, and see if they work.
Edit:
Or maybe it's the LED that's faulty. (never heard of such a situation but anything is possible) >.>
Does it still charge even if the LED is not orange/on?

Thing is though I can pretty much get it to stay charging if I don't let it lock and the screen go off? Could this still be a problem with the USB port? I'm getting worried now as I don't like the hassle of sending things back through eBay. I'm wondering if the seller bought a spare battery thinking it was just a battery problem and isn't telling the whole story. Foolishly I didn't test the device with Windows Mobile, I just went straight into flashing as I had put Android on my friend's HD2 the other day in exactly the same way...his is even an ex Virgin Mobile phone like this one. Needless to say, he is having no charging issues.

Dude dont worry , the problem is the battery ! i got two chinese battery ones and both cant charge with the phone, i have to use eksternal charger Dont worry the red and orange led flashes constantly when i try to charge it
Just buy a cheap charger from ebay , and buy a oem htc hd2 battery

Hi thanks for your reply. Mine doesn't flash red and orange though: the orange light comes on as normal and the phone reports it as charging, but after a while (seems to be when the phone goes to standby most of the time) the orange light turns off and the charging symbol disappears. If I unplug and replug again the light comes back on for a period. I've not tested thoroughly but I THINK it will stay charging when I leave the phone out of standby with the screen set to stay on for 30 minutes. I really HOPE it's a battery issue but it sounds slightly different to yours as mine does at least charge to a degree. I'm worried there's a blown capacitor somewhere on the logic board that's making the phone charge malfunction but obviously there's no way of testing until I get a new battery.
It concerns me that the seller said he had no charging problems...he must have been able to charge it somehow as the battery was full when it arrived...could I have burnt something out when flashing?!

Mine do charge to about 50 % and then it stops
Im 100 % sure its the battery becouse the battery has a circuitboard inside of it, and thats often messed up considering its made cheap in china . But test it with your friends hd2 original battery You can 2 see if the wet indicatior has been activated
the " white " paper next to the battery poles should be white and not pink, alltso where the skrewholes of the phone that should allso be white just to make sure your phone is not waterdamaget

I don't think flashing could have burnt something out. Overclocking and generating a lot of heat can burn something out though.
Didn't you receive the stock battery? Why not try it with that, and if the problem stilll persists then it might not be the battery. Either way, it will help you to test out the phone with a stock battery.

I tried it again after a few hours and it charged for a fair while before the light went off again.
I don't have the original battery as the seller has yet to mail it to me.
Does anyone else think it's worth me trying out a stock Windows Mobile ROM to see if it works? Might be that Android ROMs are less forgiving of cheap batteries with dodgy circuitry..

UPDATE
Ok so I've flashed Windows Mobile onto the device and wiped Magldr. The phone now alternates between a green and an amber light on the charging indicator. Looks like Windows Mobile won't charge it at all!
Does anyone know what this means?
I've checked for water damage in the areas mentioned and there is no sign.

Well your best bet is to send it in for repairs. But I'd suggest you test the phone out first with a stock battery.

Well I Only bought the phone yesterday so I certainly won't be paying for any repairs.
Got a replacement battery today - a genuine HTC one.
Plugged in, switched on....flashing between amber and green
I have a nagging suspicion this is going to be an eBay refund nightmare.

have you checked that the pins on the phone is not bendt? pins where battery poles connect to phone

problem solved? fingers crossed
OK so as a last resort I flashed radio 2.15 to the device. Seems that this has completely fixed the problem as without even restoring the phone is now charging properly. It seems that a corrupted radio flash had affected the charge somehow....at least I hope so.
The same problem has not come back again today at all.
Might be worth throwing this solution in a problems and solutions section as I haven't found any reference to it on the net and it might fix things for others panicking over their handsets.

That's nice.
Good for you, since it's a hassle to deal with sending back the device and shizz like that.

was just searching is anyone had a similar problem like me. to the OP yours sounds like my problem.
Had these fake OEM batteries for a while now. Until recently they have been charging ang turning off in 1 1/2 minutes. put a genuine OEM battery in and the problem is gone.
My solution was OEM can charge thru phone but fakes cant, use fakes as backup and charge it thru a desktop charger. goodluck

Serious battery problem

Hello everyone,
unfortunately I have a serious problem that I think is not related to software. From few weeks my phone dies at half a day (before it lasts more than a full day).
I have already changed the battery (by buying another original Samsung) but I have not solved anything.
It also does a strange thing: I put in charge the telephone turned off, then when fully charged if I remove the battery and insert it again, the phone will not turn on as if he had the battery to zero. If I plug in the power supply and turn it on, the phone turns on and if I detach it again, the phone remains on indicating that the battery is charged (although I do not remember if it reports 100% or less).
If I do the same full charge but without removing the battery, when I detach the charger, the cell phone turns on normally (even if it has the serious problem of lack of autonomy that I said).
Initially I thought it was a problem of some software installed that consumed too many resources or rom or similar, but after having replaced to the original ROM, after changing the battery with a new one, having tried various battery chargers, now I'm worried because the problem seems to be due only to the phone.
Even if I leave the phone turned off and not in charge, the morning after I turn it on and died!
I am seriously worried: any of you happened something like this, even with other phones?
If I search on the forums, as it comes to batteries we always talk about software installed, optimizations etc., It is very difficult with all that's out there to find some problems similar to mine!
Please help me! : cry:

Essential Phone keeps powering off

Hello everyone my brother's Ph-1 keeps shutting down right after powering up, I have tried everything from factory resetting to trying a different charger, nothing seems to work. This happened after he didn't use the phone for almost a month, it worked perfectly before.
It powers off even when on charge or connected to the laptop.
The phone doesn't stay on for more than a minute or two which means i cannot use ADB to side load an update
The phone is running Android P and the April security update patch.
Please do help me out
Thanking you

It could be corrupted though it sounds a bit like a battery issue, to me. If battery discharges too much eg it didn't shut down itself properly when battery was at a low level (they retain more charge than shown to user so it can shut down with proper procedure) & the battery ran down past it's reserve the battery may not be able to be recharged with a normal charger even though you charge it. (Thought a battery specialist could possibly revive it with a boost charge, though I've only seen these used with industrial batteries)
with a "dead battery bootloop" sometimes you can get it going by booting when connected to the charger, but you'll probably need a new battery. Maybe also try boot into safe or recovery mode when connected to Essential charger. (I'm assuming your phone not corrupted, though as you haven't given us much info about exactly what happens & what you are seeing)

The phone shuts down even when in recovery or safe mode whilst connected to the charger.
It does sometimes fully boot up and then shutdowns, but mostly shuts down while still on the essential logo.
If I may ask what do you mean by the phone might be corrupt?
Can one month of non usage cause the battery to die out?

by corrupt I mean some data that is part of the boot process causes bootloop so it shuts down, but as your phone is shutting down at different points in boot cycle I think it's probably battery
Leaving the phone turned off unused for longish periods should not be a problem normally even with a few % left in battery. And even if left turned on it should shut itself down when battery low & be able to boot up again after a month due to the battery "reserve" capacity (but possibly a month was too long). And if it was not recharged straight away and/or rebooted multiple times the battery "reserve" could fall too low and not have enough power to start/shutdown properly (possibly causing data corruption ... though l don't know if there is some sort of fail-safe boot procedure ) Then there is a possibility there is a hardware fault with battery/phone that meant battery lost too much power.
There were some tricks ie "boost charge" you could do with removable batteries that were in "deep sleep" as shown here for example
https://m.youtube.com/watch?v=TEXA7qIJ968
But they don't really work without taking your battery out (for us we might as well get a new battery when opening phone up, & there would be some risk that you damage battery as we do not know the exact charge to apply on this battery, which could cause unsafe battery) I wouldn't want to freeze my phone even though it should survive OK, as I'd be alittle concerned about long term effect on our screens small pixels (I remember the guys at popular mechanics put an old flip phone with little LCD screen in liquid nitrogen & it still worked after being warmed up!).
See https://batteryuniversity.com/learn/article/low_voltage_cut_off
for more tech details

firmware issues do not cause the issue you are describing
you have a hardware problem
sounds like a bad battery to me
good news is the battery is not difficult to replace (don't listen to ifixit I am not sure what they where smoking when they did there tear down)
https://www.youtube.com/watch?v=BCKxAQXdTJ8
don't bother with silly and wrong tricks like trying to hack the battery back to life its the wrong way todo
if the battery ever gets to that point then the battery is bad enough said

So true! )) As much as I respect the guys from iFixit, they screwed this one up pretty badly - basically, made a tutorial on how to destroy your phone. Fixez.com did much better.
