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.

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

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

What is the solution?

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

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

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

The first time I flashed the PDA I ruined my battery. This time I thought I'd be smart and I put in the old battery while flashing. After flashing I put back the new battery and now that one is broken too! It wasn't even in the PDA when I flashed it. How bizarre is that?
I have to admit I did not fully charge that new battery before flashing, but I figured it would be safe since it wasn;t in while flashing. The battery worked fine the day before I flashed my phone (got the "charge now or save your work" message), but after the flashing and putting it in, it just crashes at around 30% or 40%. The usual battery misery.
Maybe I should try fully charging it and then flashing again. Trouble would be how to get it fully charged though. I always felt charging cuts off early on the "broken" batteries (pull the charge plug and stick it back and it charges for a while again).
I managed to restore my battery to good health by completely discharging it in bootloader mode.
First I completely charged it. When the led went green I pulled the shcarge cable and connected it back again. After doing this a few times it doesn't stay orange so long and then I stopped and left the cable disconnected.
I reset the phone (on full battery) and then I set the unit to boatloader and waited for it to completely discharge. I reset the phone again (on empty battery) and low and behold my trusty "charge now or lose data" warning came back.
BTW I reset the PDA hoping maybe it would store the power levels. I remember that trick from my Palm days where sometimes you had to reset a PDA on full battery to calibrate it.
I charged it back to full capacity and started using the phone as normal. When the battery was empty I got no crash but a friendly warning telling me my battery was going low. Phew.
Will try the same with my other troubled battery over the weekend.
I have the same Issue.But , I think it's about Rom.
and I'm try a lot of ROM version ,only one Version canbe use more than 3 day.
I can't find any reason ,.
discharge in bootloader ,I do it ,But battiery is same time for used.
Hi all:
i know i have been braging lately a lot on the forums about the battery issue after upgrade to wm6.
BUT- after actually surfing the net for like 2 weeks non stop, i found on several sites a solution which i think would end this "IF" someone has it.
Theoritical Explanation:
it's said that when upgrading to wm6 the battery has to be atleast 50% charged "this is wrong" .
battery has to be 100% charged because for example:
if your battery is say 60% and you upgraded to wm6, the new ROM will mark the 60% as your 100% battery hence why it drains so fast.
that's why you need to charge to 100% first before upgrade BUT the only way to make sure the battery is really at 100% is to remove it and charge it in the cradle separetly until the lid on cradle changes from amber to green.
after that put the battery in your BA and start the RE-upgrade if you are on wm6 already or Upgrade if you are on wm5 or wm2003SE.
you should notice the difference, i'm currently testing it for the 2nd time, to make sure it is the right solution.
P.S. am only a noob so excuse me for the unorganised post.
Pls someone test this aswell
Regards
The battery charge level has nothing to do with the OS, its part dependent.
If i get you right, what are you saying is "if the battery level is 60% on flashing, the new OS will take 60% as being the 100%(maximum) level of what the battery can go".
I think that's wrong.

yes, hence why the battery and BA gets to warm or hot while charging as it cannot exceed the 60% mark which is marked as 100%.
i think it's the only logical explanation
Any battery get warm or hot on charge (or one some type of charge, like car charge).
I may say b*** s***, but after upgrading to WM6, my battery is acting as in WM2003; some software (like HTC home) is draining more, but nothing isn't abnormal; i still get with a 2400 mA a normal day of BA use (PDA+phone).

the ting is my battery was working very good before upgrade with wm5 and wm2003SE but after wm6 this happened, andnever had i get the battery and BA so very hot like ths.
i finished the re-upgrade after charging battery and it's draining is much better, dropped in 1.30 hours 50% but still getting much draining, it used to drain to zero in 1 hour

Did you disables infrared on the new install? This might take some extra power.
nothing wrong with the OS , i believe it's a psycho matter maybe ??? my battery was 94% charged .. i took the device and went on a trip .. 4 hours with TCMP on listening to Mp3s .. i went back home after 5 hours it was 53%. Sounds good for me. 1450mAh and i charge it every 2 days with normal consumption. Maybe ur batteries are getting old because with No plugins installed it's just as good as WM2003SE.
Battery status - Its possible
ahassouna might be onto something. Logically I know this sounds unlikely. However I recall exactly the same point occuring in the smartphone forums when an OS upgrade came about. It was common knowledge that for the HTC smartphone you should have you battery fully charged when doing it. It was widely tested in the forums - www.modaco.com and generally accepted back then that for best perfromance your battery should be 100% when upgrading. BTW - in my opinion this is the best ROM ever released for BA - big thanks and respect to Helmi!
if it's so you never come back after upgrading with non fully charged battery.
I think that's wrong.
Emm let's say u were right, so i assume that the OS wont determine the correct battery level. So logically, when u get a 0% , the battery is shown as empty while it is not. So if u think a bit , when the OS indicates that the battery is empty, it shouldnt turn itself off because in fact IT IS NOT. So if you get ur device to turn itself off without being able to power on again , that means that the OS was right and it was 0% for real. ( Correct me if i'm wrong )
as the Matter of fact, wm6 is slightly 'heavier' than wm2003, it contains more drivers and stuffs. so it will consume lot More resource than wm2003. I think battery draining also closely related to the read/writing speed of your sdcard, how big the capacity...
My SX66 drains equally under all three OS's, Though I must admit I quickly upgraded from WM2003SE to WM2005. Ran WM2005 for almost a full year, good battery drain, WM2006 seems to drain the same thus far
I would have a look at your battery, there cheap to replace on ebay and such.
Slide2Unlock
Do you use Slide2Unlock? I confirmed that the software was draining battery faster especially ver 1.216. I uninstalled it and my battery back to normal.
I hope it helps.
I don't believe that would cause any problems...the OS is independent of the battery. Anyway, my battery use is only slightly higher in WM6 than WM5.
Your battery can be at any level when you upgrade the ROM...I really cannot see how the OS would "read" the status of the battery and set that as the 100% level.
Try running your battery down to something below 50%, then reflash your ROM...now what does the battery meter show? I bet it shows the same as before you flashed it, below 50%.

Yes. In fact every battery has a internal chip for charge controll and status level. OS reads the status of the battery by this chip.

no i don't use it, i finished flashing for the 3rd time with a "3rd battery" Still same problem BUT draiing is less than before but still 1-2 hours max without any calls and drops to zero.
am begining to think my BA went razy for some reason.
P.S. i have no apps or anything installed other than flashing the ROM.
My BA drains normally. I have 2-4 days of standby with occasional calls and usage. The backlight auto-closes in 30 seconds, the power goes off in 1 minute.

Exactly...so the first post is wrong...the OS reads the status of the battery and it doesn't matter what charge status the battery is at when you reflash...the battery status circuit will show the proper charge percentage...
I was wondering... What kind of symptoms do you get when your battery is starting to die? I'm getting some crazy battery drain problems. First I've got a good 50% charge. I make a 10 min call and the phone restarts with the battery at 0%. No warnings or anything. I've got a couple new batteries coming by mail. I was just wondering if maybe I have some other problem with my phone. Thanks in advance.
Hi!
got a similar problem.. I don't know if it is a battery problem or a SW problem. Please, let me know if a new battery solved yours.
thanks

Hi, just check my post at: http://forum.xda-developers.com/showpost.php?p=2508856&postcount=5
You can download and use PowerDetect from there. charge your battery to 100% and run the program. It will give the % of battery and the voltage. it logs the results to a text document. While running, your wizard will turn off/restart. after that, charge again to see the test results. If you see the voltage is running low very quickly, then your battery will be dead.
just buy an new battery and you'll be fine
good luck!
battery would start fully charged at 100%
used it for maybe 10 min? and went down to probably 60%
a moment later it's down to 40%...
try to wrap up your stuff and the 20% warning comes on
that's the battery dying. i bought a new one off of amazon and now it tends to go down slowly. i can use it off and on the whole day and it ends up 50-60%, pretty close to how it was when it was new

I dry up mine pretty fast! but i am always using the mobile.. can't get enough of the 9100
i did a burnout test once. Light at max level, screen tap sounds, bluetooth and wifi on, and connected. IE and MSN, with multitasking between both. I can only say lol.
It was the battery. New battery new lease on life. Working great now. Now I have to do some USB repairs from having to charge so much...
this morning it was 100% and when i got home it was at 87% but after i did a soft reset it said 15% i did another resent and now its at 45%, i cant get it to read the batter correctly anymore?
charged for AROUND AN HOUR and how it says 100%

i am having the same problem after MR2. it was abt 56% after a soft reset(Phone was really slow kind of hanged) wend to 15% and another soft reset back to 54%. some bug i guess
http://forum.xda-developers.com/showthread.php?t=682270
it seams that it is some bug but no one has found yet an solution..
come on guys, too focus on how bad the x2 is and forgot about the basic problems.. has anyone come to mind it might be the battery?? i had that problem too thinking i have overcharge the battery so when out and buy a new one now its all sweet.. and send the old one back SE they gave me a new one.
well hard to say but it is from the start-brand new battery and from the beginig..li-polymer battery are hard to overcharge-they can be charged even if they have 70% or 80% power still in it...but l have confirmed in Serbia several cases of battery issue-so are they all "overcharged"?
ive had at least a dozen mobile phones over the last decade and ive found with practically every one of them that if you do a reset or turn the phone off the battery meter will drop. this is nothing new and not specific to the X2 or even sony (ive had nokias and philips phones do it). i dont know if its because it takes extra grunt to restart the phone or it loses calibration or what. the battery meter guesses the percentage of power based on the voltage so its not an exact reading anyway. ive found that popping it on charge for a bit seems to sort it all out again.

not that it wont stop charging, its just the meter changes erratically with no reason, frim 90 to 4 back to like 50 just from a soft reset
but now how to stop charging?
when my phone is turn on and connected to a wall charger,then charger charge the battery to 100%..and that is that..but it still charging. when phone is off and connected on charger,then it charge to 98%..that is what it shows when i turn on the x2. l have tried battery calibration procedure and nothing..
I noticed this happened on MR1 when removing and replacing the battery (as we all needed to do soooo many times ). Something must be happening with the contacts. I just made sure they were clean and reinserted my battery and haven't had a problem since.
has anyone noticed that when you charge the battery
when the phone is switched off, that the battery does not stop charging? the big battery icon keeps going up an down even if you leave it charging all night? the icon is still showing charge..

My previouse post is a guidline for charging.
With Li-Po's if you over charge them they discharge, this is a well know fact for RC cars/planes that run Li-Po's which is why they have charges with so many settings to get optimal performance and warnings and cut off when fully charged if the cut off/discharge does not take place it makes the Li-Moss (dendrites) unstable, when they get long enough they can short out the battery and cue explosion
When on charge for a long period have you noticed that the battery gets rather hot, and after 30/40 mins it is cool again?? this is because it has been over charged and is discharging to stop it from exploding. it also explains why even tho its been on charged all night its only at %60 odd because the discharge has taken place.
and i have just been told by a work friend that HP are doing a re-call because of the above.

All this you provide is ok,but problem was from the start-brand new phones were bought and from start this happens..so SE sold us defect battery? Funny, but there is no point to talk about over heat and overcharge when simple..battery icon large one when phone is off do not stop or go off display few people tried 9-12h and it still is there. Battery is no hot..it is hot after 2h-little hot..after that phone is cold. l believe that something is wrong with registry keys for charge time..l am not a programmer or developer but l dont think that we all fu*** up our batteries ..this is not a first phone to us..so we are not amateurs in usage of battery charge.
i dont understand.. why would you turn off the phone to charge it? it does appear there is still an error but this isnt necessary and wont charge the phone any faster or more efficiently.

Some times l do not want to be disturbed and if battery is low l turn off the phone...and plug it to charge... obviously there are no body who thinks that this bug is annoying.
This is my first device with such a bug,and because l deal with mobiles(l had over 100 devices and use them form last 10 years) never cross to such a issue..and nobody know how to solve this bug.
Hey there i have a HTC Legend running cyanogenmod 7.0.2.The problem is that i can't charge my phone to 100% it usually charges to 65% and it drains very fast but i noticed that i stays on 3% for +- 8 hours with extensive use.I thought that my battery wasn't good anymore but yesterday i tried putting my battery in my friends htc legend and it showed 83% while it showed 13% on mine so i put the battery to charge on my friends phone till it charged to 100%(that means that the battery's still good)but when i reinserted the battery in my phone it showed 65% just like when i charge the battery in my phone.I thought that i could try calibrating my battery but the phone doesn't charge to 100%.I was running blay0's b0.8.4 rom before this cm7 rom and had the same issue.
Any suggestions how i can fix this.

turn off your phone, plug it all night long then restart in cwm recovery and do "wipe battery stats" ( or something like that in advanced)
restart and see
I have already tried that i have turned the phone off and left it to charge for two and a half days long without disconnecting the charger but the light still didn't turn green.This is really annoying cause the battery drains fast and when its less than 15% the orange light turns on which i don't like to see
I have the same problem with my Legend since I update from stock 2.1 to 2.2.Actualy because of this I root my Legend then i can calibrate it but nothink seams to help.After all night charging the led is still red and when i start it up it shows 75% and go down fast.(1 hour or so can bring it to 5% easily).After when i switch it off and take out battery for few second and put it back it come back to about 55%.actualy the same problem as you have.
I just live with it....i trayed every calibration method and app. and nothink helps.
On another forum one guy told me then it probably need to be recalibrated in factory because i dont have the right tools for it.
I dont think then HTC will do that for me specialy after i root it.
If you find solution please let as know.thanks

Click to expand...
Click to collapse
Then unroot it, install your carrier's firmware just the way it came with on the phone, and send it back. I would imagine it be hard for them to tell that you've rooted it.
Or just before you do so, check if the battery's still messing around before you send it back.
I have two battery's and the problem is the same with both of them.If is true then they can not understand i will give a tray...i think then this is the first think they will look it at just to tell me f**k you..hahaha
I' ve the same problem with stock legend 2.2. How can we do?help!

So this is what i tried i drained my battery completely till i had 1% of charge then i put it to charge while the phone was still on and it has been on charge for two days and i see that the phone has charged to 76% usually it would charge to 65% so maybe if i leave it for a couple of days on charge i could get a full 100% charge.So that is my last hope unless you guys find something else.
I will post back if it works for me
BTW couldn't it be a kernel problem??
All I know then the problem started when I update from 2.1 to 2.2 stock rom.so my theory is then when you flash new rom the process take some time and energy from battery and when the process is finish the system take current battery state as full which is not true because of used energy from flashing process.So maybe providing DC power with the same voltage as fully charged battery when flashing new rom may fix it.I maybe wrong but in theory it may work.what you think?
I have 2.2 since release date,and the problem is present since one month,after about 6 months 'hotspot mode' for home internet.i think is a battery problem (charge and navigate at same time for 2 hours for day)but this thread show that is a common problem!

i'm having the same kind of trouble for the past 2 months. no matter what i've tried nothing happenned. i'm running custom 2.2 , without rooting or so and charging level stops at 71-75%. drops down relatively quickly until 15% and easily can stay with 3% for over than 5 hours.... htc suggested to run a factory reset,but even this didn't help. if someone finds a solution it would be ...LEGEND...
The phone is actualy charging the battery correctly,i find that out with the multimeter.I measure the battery voltage after all night charge and even then in the phone it shows 75% and voltage 3.950 with multimether i find out then voltage of the battery is 4.220.So thats mean then phone is charging correctly just the indicator(software)doez not interpret it it right.Still is anoying to look at red led after 1-2hours of use.
I have S-ON so maybe even if the calibration app.say after i tray to calibrating then batterystats.bin is deleted it maybe not true becouse of S-ON.
Do you guys with this problem have S-OFF or S-ON?
Maybe is not related to S-OFF or S-ON but who knows...
Maybe if we charge the battery till its full and testing it like pirate81 said with a multimeter and then flash a new rom maybe that could fix it has anyone tried this??
I start to think then XDA developers forum is useless...i post my problem hier to get help from people(xda developers)which I think then they actualy know somethink about android but It seams to me then XDAdevelpers actualy dont care..end i am sorry for that....dissapointed.I see then this forum works on basic.."help your self"...where are you XDAdevelopers...we come to your forum because we need help from you...
I know you doing it for free so i should be happy for what i get but i was waiting a little bit more of interest....sorry i am just dissapointed.
Anyone find a solution?
Would it help if we went back to android 2.1
I allready trayed that..save your time...no changes.
Can't we just use someone elses battery stats file someone who's battery does charge to 100%
I have same problem for 6 months already and yes, it started when I upgraded from 2.1 to 2.2 and it's only getting worse. It was 95% maximum, then 75% then 65% and now it's 45%.
Changing battery or firmware (custom or official), wiping stats, factory resets or calibrating batteries does not help.
Now it dawned on me that I still heve 2 weeks of warranty left and I think I'll try official service.
Please let as know when you will get it back...if they change just rom and calibrating or you will get new phone.I am interestig if it is software or hardware issue.thanks
