JasJar crashes at 35% battery power

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

XDA crashes at less than 25% power after ROM upgrade

I have an XDA Exec and I have just upgraded my ROM to the newest QTEK version. Since then, I have noticed that it crashes and reboots when the power level showing on the power meter reaches about 25%. I don't believe this problem was occurring before the ROM upgrade.
Although it stops working when 25% power is showing, I do not think that the battery life is actually reduced at all. It seems to me that it is more like the guage is inaccurate now and the power is really near zero when it crashes.
I wondered if the power guage needs recalibrating in some manner after the ROM upgrade because the settings have been lost. I know that some laptop computers need their batteries to be calibrated on first use. Does anyone have any ideas or information on this?
Thanks
Mark

Mark,
did you ever solve this issue? I have the same problem. Thanks for anyone's help.

Have only just noticed but im having the same problem to so annoying

Bad news, I am afraid. It is a harware fault and needs a repair.
In the end I returned my Exec to O2 under warranty. I got it back last week but they had forgotten to return the battery. After a phone call they sent me a free brand new battery by next day delivery.
Unfortunatelyt this means that I can't say for sure whether it was a battery problem or the phone itself. The covering letter with the phone said they had found a fault and repaired the phone, but since it seemed to be a stock letter, I can't be sure.
Anyway, my Exec certainly works fine now. I can get down to less than 10% with no crashes. I definitely did not have anything to do with the ROM upgrade.

Mark,
Thanks for the reply. That was not what I wanted to hear! I am going to continue playing around with it; I can't believe we're the only ones to have this problem. Let me know if you get any more news. I'm getting tired of sending the HTC in for repairs.

i-mate crashes with battery in less then 43%
My i-mate continues to crashes with the battery is less then 43%, apparently the problem occurred when I make 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 settings showed 23%, then I made a phone call, the i-mate crashes in seconds. Somebody could inform what is the true voltage of the battery in the i-mate when it is 100% and when it is 10%, at the Main Battery settings?

Battery problem...u ccan verify this by using a differrent one may b from yr friend...

I have the same problem, its only started happening after the ROM upgrade from o2, before it would run down to 0% no problem but now it gets to 25% crashes and i have to reboot it and turn the backlight of otherwise it crashes again. Are you sure its a battery problem because ive had the same battery for 6 months and the problem only started after the upgrade.

Thanks to all of you guys for adding comments. Good to see others with the same problem. Misery loves company.
Anyhow, I can't exactly say my problems started with a ROM upgrade. I have two used universals. Here's my story:
PDA#1. Upgraded with previous Orange ROM as soon as I bought it and started having the 25% crashing problem
PDA#2. Never had crashing problem, upgraded latest Orange ROM, down to nearly dead battery today and no crash.
Hmm, to test the bad battery theory, I will swap the battery in PDA#1 with the battery in PDA #2, and if I get a crash, I can blame it on the battery. Otherwise, it's the OS. Both PDAs have EXACTLY the same programs installed from fresh ROM upgrades.

Battery test
Hi PDAholic.
Which was the result of the test with the battery.

Hi
See my previous post in this topic. I can confirm that my problem seemed to start when I upgraded to the newest QTek ROM (from original O2 ROM). However after it has been returned to O2 for a repair, I have once again upgraded to the same ROM and now it works fine.
So, it must ether be a hardware fault on the Exec or a battery fault. My evidence is not consistent with it being something to do with the ROM version.
Anyone have definitive information on this problem?
Mark

Mark: I thank you for your post--but you have to admit, there is nothing wrong with a little experimentation!
Josedias: My experiment is still underway. I will say that taking out the nearly dead battery from non-crashing pda and putting it into the crashing pda did not result in the latter pda crashing. However, I am now waiting for the battery from crashing pda (which is now in non-crashing pda) to die. If it does, the problem is the battery. I actually have another theory if none of this pans out, which I will present with my next post.

Pdahollic
Will be good to hear what your fndings are.
I spoke to o2 today and told them about the problem with the battery they tried telling me that it was software related then i told him that i was using the latest software from there website and he was like hmmm ok let me put you through to returns. Got put through and the kind person that i spoke to there said just to pop it in the post with the returns number and will send you out a new one the same day.
So i should hopefully have a new 1 by the end of the week will let you know if i have any problems

Okay, interesting results here...
I was actually unable to reproduce the shutdown on either PDA, with either battery!
I have a theory why, and perhaps those of you with the problem could try and see if it fixes your devices.
When I started the experiment, I wanted both PDAs to be as equal (controlled variables!) as possible. So, I charged both overnight until the green light came on, then did a soft reset to both PDAs. I have a feeling this might have somehow reset the battery meters in both devices.
Pretty much all PDA manufacturers recommend when you first get a device to charge it to 100% then begin using it. I do know that when I did the ROM upgrade on the device that kept crashing, my battery was very low. So, I presume that when I started using the device, the battery calibration was way off. Say that the device thought the battery was at 100%, but it was actually only at 75%. When the battery discharged to 0%, the device thought it was at 25%, and thus did not issue any warning messages. Then, without warning, the device died and would not come on without charging (which is what mine did).
I don't know for sure if this is what has been happening, but it makes sense to me.
My next experiment would be to stick a near dead battery in a device with a fully charged battery and see what happens. Although, at this point I probably "ought to leave well enough alone."
Again, I suggest to all of you to charge the device overnight to 100% WITH THE GREEN LIGHT ON, then do a soft reset and see if your problem is solved.
I will keep you guys posted on any further problems. Good luck.

Hi everyone!
A bit out of topic but I could not find any other discusion that could relate to my problem which is also related to battery.
I've got this guy who bought a brand spankin new XDA EXEC straight from Taiwan and the lame ass used it for about 4 hours without preformating the battery until it seized on him. It happend at the time of Active Sync instalation.
It did not die out sooner because he had it connected all the time to PC via USB cable thinking that this will charge the battery.
Now all he can see is the O2 welcoming screen and the ROM initialization figures.
Any ideas guys? I feel sorry for him and am trying to help him somehow.

I presume he has tried to do a hard reset (both softkeys, reset button and power). If that doesn't work, he could put it in bootloader mode, disable USB, and try reloading the ROM. Make sure he realizes that it takes a LONG time to soft reset the Universals. A common nube mistake is to keep hitting the reset button thinking it has locked up on the splash screen. Not that I would ever have done that...

I received a T-Mobile MDA Pro on tuesday and it has the same problem - but, my battery seems to die at 50% and will only power back on when the charger is plugged (mains or usb) in?

Hi guys ive just been on the phone with o2 and i have been told that it is indeed a hardware fault and that i will be getting a new one back from them in the next few days.

Qtek 13077 ROM ????
Could somebody inform what is the true voltage of the battery in the i-mate at 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 to Qteck, we needs to investigate what the the Qtek ROM this doing with the JasJar?

Anyone changed the internal battery?

I am having problems with the internal battery in my wizard. Everytime I switch battery my clock and calender resets. I have the service manual and see where the back-up battery is. I was just wondering what kind of battery it is and if I can just replace it?

The Wizard does not have a backup battery like other PDA's. It has a persistant memory model like a PC. I have never had to remove the battery so I guess the clock would reset.

Whether the Wizard has a battery or not there is definitely a design flaw. It always used to remember the time and date settings when removing the main battery buy after about 6 months it no longer does. this has happen on both our Wizards and many others. It's very annoying when you change sims and then have to reset the time and date.
So far nobody has been able to explain why this is happening. There are thoughts that it may be the new roms which have changed something in the power management.
Kiru, you say you have the service manual and have found / identified the backup battery? That would very interesting if there is one.

I remove my battery to move my sim to other phones quite regularly, and my clock/date settings always remain intact on my mini-s. If I look at battery stats on my SPB pocket plus, it shows 2 batterys. Main batt and backup batt. I always assumed the device had a backup battery to store date/time settings.....

He's talking about the small backup battery inside the device. If your sure Wizard has a backup battey, then yes its removable.
The type of battery, and volt is labeled on either side of the battery.

Just my $.02...
If this problem is less than a year old try warranty repair options?
Also, you can set the phone to update its time and date from the cell tower. I've never set the clock on my device it just nabs that information from the cell tower. Should happen as soon as you get a signal instantly...
The setting for it is under Phone -> Time Zones
Hope those help...
As i'm sure the backup battery is only used for the RTC (Real Time Clock) since the device is now persistent storage...

Just follow what FESCSteve said...and it should work....if not....then send me a pm and I can email it out to you

When i switched my mainboard my back up battery was dead, but after a couple days its back to normal, so i guess just keep charging your device and the back up battery will work again.
as for replacing it, it's soldered on so you'll have to unsolder it to replace it.

At page 37 of the service manual you can see about a "Golden Cap". It is not a battery, it is an high capacity capacitor. It works like a battery but has never to be replaced because it (should be) is charged by internal circuitry from main battery.

okay I managed to get my internal battery working once again!!!.....I think is drained due to the fact that I don't charge my batteries with my phone, but use a desktop charger. I then plugged my phone into the charger for about 24 hours, and finally, the back battery is charging (as to what pocket breeze says) It still isn't 100% charged, but it seems to be holding the time and date again!!!... just fyi I have 3 batteries for my wizard and never charge them using the phone....so that could have been my problem.

Last week my battery was totally empty so I had to charge it using my 220V charger.. At that time I also found out that my internal battery is empty when I exchange SIM cards. Last Sunday I charged my SPV M3000 for like15-20 hours but I still have the same problem...
What more can I do to make it work again?

I have same problem with my O2 Mini S. I charged it with the wall charger for around 18 hours although it took just 2 hours to get the the main battery fully charged. The date/time still reset when I plugged it out and removed the main battery.
Anybody kindly help please. Thanks so much in advance.

too bad my problem came back again....and I don't know why.....when I left my phone charging almost all day, my battery meter says my backup battery is 75% full.....then when i changed my battery.....all my clocks reset again...it's gets really annyoing especially if you change batteries alot. But does this only happen when people are using spare batteries?..and always swapping back and fourth?, I rarely use the phone to charge my battery as i have a desktop charger.

It seems that there really is a backup battery (capacitor) that can be damaged. I have read the Wizard service manual and this little component has to be replaced if this problem still occurs :-(....

both mine and my wife's wizards are only charged by the mains charger and they both loose the time and date settings when changing sims. This problem started about 6 months after having the phones so I think some component seems to fail after a while as there are many reports of this happening.
All I can say is that it's very annoying as I travel frequently and change sims often.
As for getting the time from the cell tower, this doesn't work for me for some reason.

Unfortunatly I have the same problem. When changing the sim and thus removing the battery I lose the time and date setting. I charge my phone by the mains charger or sometimes by an USB port.
Perhaps it has to do with the new ROM I use? I recently upgraded to the molski rom. Perfect ROM by the way.

I don't think it's the ROMs. I still use the original WWE I-Mate rom (2.16, the one and only update they did so far). It's possible that the ROM introduced the problem but then everyone using the ROM would have the problem which is not the case I believe.

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.
Mike

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"
What is the solution?

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.
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).
