Hello,
I need your help with the following problem:
I have been using my Jasjar for 5 days now and I have a problem with the battery.
As soon as it gets to 35-40% battery power the unit switches off without any notice.
The only way I can turn it on again if I put it on a charger, and than it turns on again like after a soft reset.
I installed the latest ROM from the clubimate but none 3rd party applications.
Please let me know what can be this problem.
Thanks,
Zsolt
same problem here
Hi Ronaldovic,
Have you tried with another battery or just the original?
I was advised to change the original battery as that might be faulty but I couldn't get a new one yet.
Zsolt
For the O2 XDA Exec the battery has a 6 month warranty. You should check the situation with the JJ
battery issues..
I had similar issue and also where on switch on the screen light goes off and back on. This seems to be linked to battery chargin "top-ups" therefore sometimes the supply from the battery is not continously smooth. Try fully draining your battery and charging fully
I have same problem with my Exec. Any solution ??
I buy new battery but...when it gets to 25%, still switch off. So I dont think it's error of battery, may be it's bug of ROM for Exec???

1 month ago I have same problem. I think is not battery.
I make upgrade by all the ROM (JAS JAR, QTEQ, MDA PRO ecc.) but the problem I have not resolution, and 2 week ago my pda (MDA PRO T-Mobile) go in htc warranty.
Sorry for my bad english.
I have also noticed this problem a few days back. My Jasjar switches itself Off when the battery goes down to 22%.
I never used to have this problem when my Jasjar was with the original factory installed ROM version which was 1.13.53 WWE, Radio 1.03, ExtRom 1.13.137 WWE. When this ROM was installed I used to get the first low battery alarm at 20% and when the battery went down to 10% the screen would dim out and the SD card would deactivate, but still the unit would not shut itself out.
I installed the updated ROM when it became available in March which is 1.30.76, Radio 1.09.00 and ExtRom 1.30.164 WWE.
I am not too sure if the problem is linked with this ROM as I usually never allow my battery to run that low. However a few days back when I forgot to charge my battery I noticed this problem. I repeated this deliberately a number of times and each time the Jasjar shuts itself off exactly at 22%.
Just wondering if there are any solutions yet.
Regards
Same here, device just dies @ 26%. Was going to buy a new battery, but that might not resolve it?? *sigh*
RE
This battery issue has been discussed in two other similar threads.
In my case I just changed the default battery to a OEM one and everything works fine :lol:
Isn't the default battery an OEM battery? I'm tempted to buy one of the 1750 mAh batteries off of ebay (original JasJar battery is 1650 mAh) - is that a bad idea?
Try overnight charging of the battery for one or two days..this will solve yr problems... :lol:
Hi,
hard reset to your device, don't forget to get backup contacts, sms and data.
battery issue
I've had similar issues. Screen goes blank when battery low, plug in to charger and all is ok. What I've found is sometimes, not always, the battery screen brightness has gone to 0, but on-mains is set for full brightness. I never changed it, so maybe the device is trying to save power itself.
MNB.
Same here. My Jasjar dies sometimes when the battery is on 60%, 50%, 30%, 20%. etc. If I use the internet or camera or something then it will go dead, but not everytime.
Sometimes I can use anything and it will last till about 10% when the SD Card disables, then I charge it.
Don't know what to do. I don't want to buy a new battery if I'm not sure that is the problem.
Yes the same on my O2 Exec. Crashes at around 32% no matter what. Only remedy is to put it on charging again.
This started after I upgraded to the lastest O2 Rom; prior to that there was no problem whatsoever and I could go down to single digit battery percentages without any issue.
Is it the new ROM? Is there any work around to this malady?
Thanks to all who reply, in advance.
Cheers.
Well judging by the number of threads on the subject this problem is very widespread, check out the threads below:-

-----------------------------------------------
So can we say that downgrading does not fix it, or removing certain software combinations?
has anyone actually proved that replacing the battery works or not?
With the issue this widespread (and across carriers) has anyone tried to contact HTC about this? I still have my doubts that this is ROM related, seems more likely to me that many of the initial batch of batteries have gone bad.
My battery is on order with expansy. Expect it in the next 4 to 5 days and will definitely let you all know of my experience with the new battery

Hi!
I'm using the latest QTEK ROM with A2DP.
The problem is that my set blacks out at 38% battery power and refuses to power up after that unless I re-connect to the AC for charging. It happens a couple of times already. Any setting(s) in the Universal to check this?
I remember I managed to get the battery level at real low level (less than 5%) previously prior to the ROM upgrade.
Thanks
Hi,
I have a similar problem.
I charged the unit till 100% then reflush the Rom

RE
Hi JoseF
Thanks, however, I'll consider this as my last option
Meanwhile I would like to get more feedback on this issue
Qtek 13077 ROM ????
My i-mate continues to crashes with the battery is less then 43%, apparently the problem occurred when I made the upgrade to ROM Qtek WWE_13077_130176_10900, was looked like that this version has something that change the battery configuration, since Qtek 9000 comes with 1750 battery mAh? I reinstalled the i-mate ROM 1.30.82 and the problem persists?
I made a test leaving the i-mate on, without using the radio until the battery miter showed 23%, then I made a phone call, the i-mate crashes in seconds. Could somebody inform what is the true voltage of the battery in the i-mate is 100% and when it is 10%, in the miter?
I have charged the unit till 100% led = Green, then soft reset, the problem persist?
Now I am 100% certainty that the problem occurred when I made upgrade for Qtek, we needs to investigate what the the Qtek ROM this doing with the JasJar?
Ive 3 batteries
The standard 1620mah dynapack which works fine 100% to flat no worries
A 3200mah extended which will charge to full but dies at 43%
(the guy replaced it with another which did the same thing)
and
A 3000mah which will go flat ok but wont charge beyond 47% and the orange light stays on forever, although luckily it doesnt fry.
has anyone had any of these extended batterys work ok?
Just to add a bit of info, all modern li-ion have a built in fuel guage chip which tells the device its in how much power is left in the cell. so its possable this is a battery issue rather than phone problem

RE
You may be right about the battery thing
However, I've tested my existing battery to very low level prior to the ROM update without problem
And with other feedbacks in this forum I doubt it could be a coincidence that our batteries are having the same issue.
I would rather think its a ROM thing.
I'll need to test my battery on another Universal before confirming.
I just tried to flash to an older rom but got a country error, there seems to be no old orange uk rom i can find.
Im a bit new to all this rom flashing business and also wanted to try an older rom to check out the camera as im not sure if i have a realy poor camera or if there is a software issue with that in the new orange rom also as one guy in another post is getting far better results out of his camera mines like a real snow storm in the dark parts of pictures
RE
Yes, the new QTEK ROM update does cause the camera quality to suffer especially when in night mode
Well, just have to wait for another ROM update to resolve these issues :roll:
Fosa or Zarn
You have a digital multimeter?
Case yes: You it could measure the voltage of the battery when is total loaded 100% led=green, and when the battery will be flat 0%. This test would be excellent to verify if the Battery power remaining is correct. Currently when my battery is with 3.28V = 55% in the battery power remaining = crashes.
ok, can do, not that it will help much unloaded.
I'll charge the original cell and post the results shortly.
The battery management wont always turn the battery off at the same point as the battery ages it will change. You have to bare in mind that a battery is a little like a piece of rubber the harder you push on it the bigger the dent but when you stop pushing it recovers its shape.
The same goes for the voltage of a battery, when you draw a large current the voltage will drop further than if the device is in standby but once you disconnect the load there will be an amount of recovery
li-ion batterys are far more complicated than they first appear.
The battery is by no means connected directly to the phone.
there is a microprocessor in the battery that controls both charge and discharge via 2 fet transistors, buy doing this it protects you against the battery exploding/catching fire from over charging or over discharging.
As far as im awaire the microprocessor will adjust both switch on and switch off from many variables not just voltage drop.
The phone its self mearly supplies power to the charger built into the battery and draws power from the battery all the measurement and battery managment is within the battery
This is why the battery suddenly just stops and you need power to bring it back to life.
so in theory no matter what the condition of the battery it should always give a full scale deflection from full to empty as the onboard management should know how much capacity is left in the cell and report this via the data lines to the phone
If you connect a bulb to an almost flat li-ion battery you will find little drop in brightness before the battery just cuts power totaly to protect the cell within from over discharge.
Something that springs to mind that hasnt been mentioned here is have you checked all 4 battery contacts are clean? just a thought because the two larger outer pads provide power while one or both of the smaller pads send data on the charge status to the phone.
heres some interesting reading
http://www.batteryuniversity.com/parttwo-34.htm
Intresting reading on the care of li-ion as they dont like being either fully charged or fully discharged..strange eh...
http://www.maxim-ic.com/appnotes.cfm/appnote_number/128
http://www.intersil.com/data/an/AN1174.pdf
two examples of li-ion battery management.
safety law dictates any li-ion that is user replaceable must have one of these little chaps built in.
hope that makes sence

RE
Sorry zarn, but I don't have a digital multimeter.
Is your test going to prove that the battery is going to its end of life soon?
How could that be since the Universal is less than a year old? :roll:
At any rate I'll be testing my battery on another Universal without the QTEK ROM update to determine whether its a battery issue or the ROM update issue.
Im just going to do it out of interest... like i said in the previous post its not likely to prove anything except if the guys battery is totaly out of whack
Dear Fosa and Zarn,
I’ve already known those URLs:
http://www.batteryuniversity.com/parttwo-34.htm
http://www.maxim-ic.com/appnotes.cfm/appnote_number/128
I liked very much this article:
http://www.maxim-ic.com/appnotes.cfm/appnote_number/128
However, when I asked to verify the voltage of the battery and without taking it off the charger, I’ve put two tiny wires on the terminal of the battery, in the manner I could verify the voltage without taking it off from the Jasjar. Last night I’ve left it charging until the green-led light and I’ve noticed that the voltage was 4,231V = to 100% on the battery power remaining miter.
I’ve did a test putting the light of 4V to discharge the battery, and at the 2,83V, it disconnected automatically (stopped to supply current). In more or less one minute, it starts to provide energy again, in other words, the protection circuit of the battery is Ok, and is not with this tension (2,83v) that the Jasjar stops, and only when is 3,28v.
I’ve got the feeling that the problem is on the ROM, however I did reinstall the original ROM and yet the Jasjar still crashes at 58% of the battery(= 3,28v).
Before making the upgrade the miter was going from 100% to 5% without crashing.
With the ROM Qtek WWE_13077_130176_10900 the miter shows 100% to 42%, and at this point it starts to crash.
I’ve already bought a new battery just to test it, but it still not arrived from Hong Kong, and as the customs is on strike here in Rio de Janeiro, Brazil, I don’t know when I’ll get it.
Until now I think the problem is that the Qtek ROM made some changes on the firmware or in the register of the battery, changing the miter calibration.
Battery results
Im suprised it cut of that low, thats very low for a 3.7v li-ion, thats more what you would expect from a 3.2v.
Anyways, as requested heres the resuts of checking the voltage at various points.
This is using an original dynapack 1620mah battery as supplied by orange with the phone, but its around 3 or 4 months old now so far from fresh.
the meter used was a Avo M801 (not a cheap one though is probably due to be calibrated...)
100%----4.16v straight off charge still warm
75%-----3.93v
50%-----3.78v
38%-----3.76v
25%-----3.73v
10%-----3.65v
5%------3.63v
cutoff----3.58v
Im going to do the same with the extended batterys im having problems with just as a comparison, will post the results here if anyone is interested
Whats going off here...?
I just put one of the extended batterys in which was fully charged..
to be greated with a blank batery bar, and unknown in the chargeing remaining window... unpluged and repluged the charger and was then told battery at 225%
doh.....
Jasjar battery miter
Hi Zarn
Thanks a lot for the table of % * V, now I am certain convinced that the Jasjar miter needs to be calibrated again, I believe that the problem is the DLL or the responsible register for this detail(miter)?
While I or somebody of the forum does not find the solution, I will continue using this way, because the battery still lasts for 24h.
RE
OK guys, bad news
I used my battery which knocks out at 43% from my QTEK 9000 set and put it into another QTEK 9000 set without ROM update and it also fails to boot up unless I connect it to an external power
I hope that QTEK can release a small ROM update to resolve this issue
so hang on..
you put your battery into another non updated rom handset and it still wasnt working properly...
surely that means your battery is at fault not the rom..
cant u borrow the other guys battery for a few hours?
Are these original batterys were talking about btw (1620mah dynapacks)?
or cheap replacements?
RE
Hi zarn,
My battery is the original default battery....the Universal is less than a year old
Could it be that the new ROM update has changed something in the battery...maybe the IC chip in the battery, if any?
RE
zarn,
If you'll read another similar thread you'll find many others with different variants of the Universal facing the same problem after upgrading the new QTEK ROM update with A2DP
Are you saying their batteries are faulty too...such a coincidence?
Hey everybody ..
I bought myself a nice o2 xda mini s .. ... i'm really hapy with it .. at first I had some trouble changing the rom .. 'cause i have a G4 chip .. but thanks to risidoro's step by step guide i managed to do it .. (THANKS RISIDORO)
My only problem now is that my battery life lasts not even a whole day .. when i use the ppc as a normal user .. lets say .. about an hour of talking . maybe some gaming ... a litlle music .. internet once in a while .. I'm already on 20 - 25 % ... I thought it might be my battery .. so I tried the whole uncharging .. charging to full thing .. but useless ..
I saw some 2400 mhamp .. batteries on ebay .. does anyone use them ??
do you have the same problem ??
any Guru I seek your wisdom ..
I had the same battery life issue after upgrading the ROM. However, it only lasted a few days.
I found that keeping my phone on the charger at night to keep it fully charged for when I was away from home solved the issue in about a week. Every day before heading home from work, it seemed my battery life would increase by about 5% over the "almost dead" battery the first couple of days after the upgrade.
Now -- 2 weeks later -- when I leave work at the end of the day, my battery meter shows that I still have 80% - 85% battery life left. (But I still keep it on the charger overnight -- every night)
Just make sure you keep the battery "topped off" in order to avoid the issue. It WILL come back up. It just takes a few days to get there right after upgrading.
It also depends on what software/plugins you run. E.g., I ran PhoneAlarm for 24 hours, and in 4 hours it drained 80% of my battery. <uninstall>
Something doesn't sound right with your battery. I have my K-JAM for 9 months now and during a typical work day I can:
1. Play audio over BT A2DP for 1:30 HRs
2. Surf the web
3. Retrieve emails
4. Read avantgo
When I get into work I am at 90% battery. Keep in mind that I am also Overclocked at 221 mhz! I also have my K-JAM loaded to bear with sbp pocket plus, MS VC, GsPocketMagic, Pocket/Contact Breeze, Pocket Weather, and SmartsKey.
During the weekend I can go all day using the phone periodically connected to my BT headset (non stereo) and get home with 60-70% battery life.
'Double battery' from ebay
Hi Silvernrg,
I had the original battery for a while.. it lasted from 1 day to 1.5 days depends on usage and how many phone calls I had.
I found a battery on ebay which is 2350mAh (almost double?) which comes with a new back cover (or a door) for the wizard.
Yes, the device looks more bulky now but the nice thing is - I get to use the wizard now for something between 3-3.5 days without recharge. It is critical for me since many times I'm on the road in business trips and I don't want to pull out the charger in all the countries I visit (I already forgot my charger one time in one of the hotels...).
I paid about $16 for the double-battery on ebay and it was sent to me from Hong-kong (to the US) quite quickly (I don't remember the ebay seller but if you can't find one on ebay, I'll dig into the history and find the seller).
hhmmm i also just recently acquired a dopod 838 a variant of htc wizard. when i 1st bought it in singapore i dun hav access to a computer so i jus install wat ever i can to the device using my eten and an mini to sd card adapter. i didnt use phone alarm then and battery life was fantastic with music and wifi and sms and calls. now that everytin is installed including phone alarm 1.52 my fone stays at the top 100% for long time then drains very2 fast after. so far i havent let it go down below 50%(only once). i got an the today overclocker and the omap but i only use it if i play games. movies with wmv lags no matter if i use tcmp or windows media and overclocking wont helps. avi is fine though. dunno if this is normal but im really convinced that stock wizard out of the box will last a whole heaps longer than customised with apps wizard. i havent upgraded my rom yet. it comes with 2.21 IPL and SPL and im really confused with the posted instruction on how to upgrade and dun want to turn it into a brick. will upgrading it to 2.24(is that the recent rom) helps battery life to be better or worst? what extra stuff it have over 2.21? i dont want to lose the extended rom as it got the australian customisation. i already got a2dp using the reg hack and the tornado.cab. quality is not that great. so sticking with the standard headset which is great.
Hello,
I have a new S200 and i noticed that every time I charge the battery its life time is shorten - I have omega battery pack installed and in first few time with a fully chard battery the battery meter was at 5 hours but now after 3 weeks a fully chard batters has only 3.5 hours left .
is it possible ?

I have the same problem with my Prophet -
I have a new Prophet, last month the battery lasted at least 5 hours ( I am using a battery plugin that show the battery time left ) and today if I get 3 hours I am glad , no changes ware made to the device .
I turn my Prophet Off every night - could it be the problem ?
You didn't enable the bluetooth or wifi option? Because those eat up battery quite fast. And did you do a rom update? Some gsm updates cause more drain on the battery.
And perhaps it could be some programs use up the battery, but can't be sure about that though.
My BT is enable because I use BT headset all the time and I'v upgraded my rom to"RUU_Prophet_220734_2207114_024721_QtekWWE_Ship.exe" .
I heve no programs running at all (except 3 from the startup).
But the main problem is not how fast the battery ends, but a full battery last 3 Horus when a month ago it lasted 5 ...
Mine discharges in a day, without any call made and only 30 min of usage
Have U tried switching the IRDA off ? 'Cause by default it's on.
the irda kind of doesn't consume at all..
I guess I had this trouble with every phone I got, the first 2 weeks are always giving better battery time, and it quickly decrease to a more "stable" state... Don't know why btw...
Are you still noticing a shortened battery life now compared to last week ? Keep testing, I bet this is already gone.
i doubt that it gets to a "Stable" state. i've been experiencing the same strange issue for 2 weeks now, in the exact same conditions as described in the first post (battery pack pro installed). i don't use IR/BT, i have no viruses, it's just the same phone. it also turns off from time to time, on no apparent regular basis. i am just preparing to rewrite the ROM, perhaps it helps.
p.s.: i've been using it for some time now (since it came on market), so it's kind of strange this started happening so sudden.
if there are no other obvious reasons you might try this tweak, which, they say, is helpful sometimes. I did it and now my phone loses 1-2 percent in standby mode in 7-9 hours and one battery charge lasts for 2.5 days of moderate use. good luck.

Did you install the A2DPfix.cab to avoid the skipping 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.

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.
Mike"

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...

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.

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.

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.
