Main battery falsely shows empty after charging - JAM, MDA Compact, S100 General

I have a really big problem that won't go away, even after 2 warranty replacement devices, new charger and battery.
I use my MDA Compact for a while until it needs charging. I put it on to charge; at this time the backup battery shows 100% and the main battery say 17%. After a couple of hours showing the steady orange LED I turn on: now the backup battery still shows 100% but the main battery shows empty. If I fiddle around doing soft resets and taking the battery out and putting it back in again I can usually get the MDA to show that there is 100% charge in the main battery. The battery is charging, because I can then use the Compact again for 2-3 days as normal, during which the battery level slowly decreases in response to usage.
This problem has me desperate. I have sent the device back and had a replacement twice, to no effect. The last time I sent the charger and battery as well, and they are supposed to have been replaced (can't tell if that's true or not). I've tried only charging from mains charger and not from USB. I've tried hard resetting and not installing any software. None of these helped. I use the same SIM in my XDA1 without any problems, and use the same USB port for syncing, again with no problems.
I've seen several threads about the backup battery reporting empty, but none about the main battery. Has anyone else seen this? Any suggestions for stopping it?

atom battery not getting charged

My atom is not getting charged.When i put it on ac adaptor it shows charging but even after 10 hoiurs the battery is empty and after removing from the power the phone shows main battery very low.
I tried charging thru laptop and same problem.
i have changed the battery also still the issue remains.
advice.
praveen
Yeah.. Atom behaves strangely sometimes.. In my case, some times when I switch on the bluetooth and try to charge it, It does not charge. But it seems to use the power coming from the charger to stay alive and operate normally (even if the battery is completely exhausted).
any suggestion how to make my atom charge
my xda atom started doing the same thing, I would plug it in and it would say that it's charging for about 5 seconds then the battery indicator would say full. Then I would unplug it and it would die out. I tried both charger & usb and the usb wouldn't work at all. So what I did is, I removed the battery let it sit for a minute. Put the battery back on and plugged the charger back in (without turning it on) and it's working. I was actually doing a search on this issue for the past couple of hours since this is the first time I've encountered this problem, but the phone seems to be charging now. I'll give everybody a update tomorrow to see if I have to keep taking out the battery everytime I want to charge it.
My problem is a bit different.
My Atom Exec charges with the USB cable synced to PC, and with one specific wall charger (specs: Input: 100-250V, Output: DC 5.5-12V, Max 1000mA, Min 150mA)
But it won't work with any other charger I try it with, even Universal charger I used to use with my HP iPaq. Is there some kind of trick to charging the Atom?
I as well have had this annoying problem happen a few times. I have a second battery and it happens with that battery as well so it has to be the Atom not 'reading the batteries' properly. As posted I have also found taking the battery our for a short time them putting it back seems to fix the problem untill it happens again
Try WM5torage. It will make your phone appear as a card reader in windows. Now pc will supply power to your device. Nice software trick.

Battery drains way too fast

Ok I am a new member to this whole PocketPC thing since I just purchased my first PocketPC which is an i-mate JASJAM. I honestly think that it's a great product with a lot of features and potential. My problem though, lies in the fact that I haven't had the chance to enjoy it for a full day yet. Ever since I bought it, I always charge it for like 7 to 8 hours, even though it fills up after like 3, but i leave it on charge anyway, because I was told that "that's what you should do!".
Anyways, no matter how long I leave it on the charger, once i take it off the battery begins to drain like there's no tomorrow. I'm talking about going from 100% to 0% within 5 hours, while on FLIGHT MODE. If I turn the screen off then it might last for an extra hour.
Surely this can't be something normal, and I have been beating my brain trying to find a solution. As far as ActiveSync goes, I did the tweak that stops its automatic scheduled syncs, hoping that it would be the problem, but to my disappointment, no luck. Also made sure that no programs were running in the background. It came with a battery with a capacity of 1300mAh and then I bought another one hoping it was a problem with the battery. The new one had a capacity of 1350mAh, not much of a difference but it was all I could find. But there's no difference between them whatsoever, when it comes to battery life.
My first question is whether it is possible that this may be a software issue rather than a hardware issue (such as a power leak)?
If it is, then would upgrading the ROM or Radio or upgrading to WM6 make any difference?
Problem's that I don't have the phone on me right now so I can't give ROM or ExtROM versions etc., but I do know that it is running WM5 with AKU 2.3 and Radio is either 1.21 or 1.31.
N.B.: Until I get this issue sorted out, I am using a Nokia 6680 which has an average battery life of 3 days (72 hours), so should I be expecting something in the vicinity with my i-mate?
Well it sounds as if you've done all the obvious things. There is a power saving registry tweak in the wiki somewhere but that should not be necessary just to bring it to normal power consumption. If I don't use mine much (not on flight mode) I'll get a couple of days at least.
A ROM change might help a little but if you have a warranty I'd be tempted to use it. Radio change is unlikely to change things if you have been testing in flight mode.
Anybody else got ideas?

The only problem that I have with getting it fixed or replaced under warranty is that I have to send it to another country. So I am trying everything I can do before going through that hassle. So is there any test that I can carry out at home, or a certain diagnostics software that can test the phone for me?
Would a digital multimeter help if i can measure the current being drawn from the battery? What should the current rating be for the phone, is it 1A? Because there is one other interesting thing i found while just snooping around, there is a sticker that just has 5VDC and 1A written on it, and it's stuck to the phone under where the battery goes. I can only imagine that this is the voltage and current rating for the phone. The interesting part is that the battery that came with it, as well as the one i bought are both 3.7V batteries.
:-S
Best to just update your phone.... But becareful! read and research on flashing b 4 you do it... VERY IMPORTANT... USE only softwares for your phone...
I wanna make sure that anything i do doesn't void my warranty as well.
Used their offical update for your phone... However, my friend brick his phone and sent it back to the company and they replace it for him... I dunno if you would have that luck however... if ur careful and read all the information... and ur computer is stable... you shouldnt worry about it bricking ur phone...

The ratings you see written inside and the battery ratings are just standard - nothing unusual there. You could test current draw etc but even if you find it a little high it doesn't really help you to pin down a problem save to say it's the phone and not the battery. However as you have two batteries it's fairly reasonable to say it's not the battery. (reasonable but not impossible of course that two batteries are not working as they should).
Unfortunately we do not yet have our hands on the test file that HTC use.

I guess I have no choice but to get it shipped back. Thanks for your help guys.
Are you using a wall charger or a trickle-charger such as the USB Cable? The wall charger is the only way to truly charge it to full.
If you are using a USB charger or other trickle charger, after the device says it is fully charged remove it from the charger for about 2 minutes and then reconnect it. It will then charge (most of) the rest of the way.
If you don't do this, the problems gets worse and worse. After 1 day, the trickle charger may get you up to a 90% charge. After two days, 80%, etc. After a week you'll only be holding half a charge, even though the device is reporting a full charge while on the charger.
Another tip I have found is to perform a soft-reset after removing it from the charger, particularly if it has been plugged in for a long time at full charge (more than an hour or so). It seems like the device doesn't always detect that it has been unplugged and tries to suck down juice as if it were still plugged in. If you have noticed that your device gets pretty hot when the battery drains quickly, this is probably what is happening to you.
You also haven't mentioned the programs that you are using during the day. Some programs, particularly chat clients, will drain the battery in about 5 hours, though obviously you're not using anything like this while in flight mode.
One more thing. You noted that you were told that leaving it on the charger whenever possible is the thing to do. This is incorrect. The more the battery is exercised in this way, the shorter the lifespan of the battery will be. With any PocketPC device we're all bound to charge it every night, but once it is charged you want to take it off the charger. A battery being fully charged is just as bad as a battery being fully drained, so you want to keep it somewhere in between as much as possible.
My battery doesn't last either.
I've ordered an extended life battery with its own back.
I've also ordered a car charger.
I also carry my old hiptop with me when I need to switch sims.
Apparently touchscreen phones that do so much, ie. bluetooth and wifi, eat batteries.

Wow, I am very surprised to hear some of these. First of all, are you sure that using the usb charger kills your battery capacity so fast? I mean, I almost always charge my phone with the usb charger and it seems to be quite fine. Of course once in a while I charge it with the wall charger when I am in a hurry. But I was thinking that charging it with the usb will be better as it charges slowly.
Also I usually keep my phone plugged to the usb. Indeed, I already ordered a desktop cradle so that I can see the screen while it is being charged. Is it a bad idea to keep it cradled all the time? This is what I did with my Dell Axim all the time and it was quite happy with it.
The process of charging/draining modern batteries won't shorten their lifespans. However, having a chargable battery at full charge or at no charge are both bad and both will reduce the lifespan of the battery.
So no, you shouldn't leave it plugged in/cradled all the time.
The problem with trickle chargers is altogether different. They just won't always charge a battery to its full capacity -- so in this way they are actually better for long-term battery health. This is why I said that if you want to get a full charge off of a trickle charger, you have to (usually) take it off the charger and put it back on when the device reports that it is fully charged. After unplugging the trickle-charger you'll get a new battery reading on the device which will usually be anywhere between 60% and 90%. You can then put it back on the charger until it shows full again.
Deleted, invalid, i didnt read the whole post.
Well, it seems that i was just unlucky with my buy. Thanks to all of you first of all for all your support it really did help me learn more about PPC's in general, and it also made me sure that there is a problem with the phone. I sat through what i like to call a debugging session, just following the phone's every "move". I know, sounds kinda crazy but i was just that determined. What i realised was that whether i performed the soft-reset or not, it still had a problem, even though the solution did sound very promising.
This is what happened, charged it to 100%. I also tried charging it a little more later, but that was it, so i'm pretty sure that the capacity was right. After detaching it i performed the softreset, hoping that it would help. Then i just left it over night on flight mode. Next morning it had only decreased to 90%. GREAT! And it felt rather normal, but then about an hour later, it jumped down to 80%, 70%, 60%, then 50%. Then when I held it, it felt pretty hot, i figured that whatever was the problem earlier, just happened again. So I turned it off for a few hours then turned it on again and it started off on 40%. As before seemed to be performing quite normal, then within a minute it heated up again and jumped down to 20%. And that was when i just lost my nerve and packed it to send it back to my retailer.
I am now convinced that the phone is faulty!
Yes, it very well might be.
My device has drained suddenly a few times, with the exact same heat problems that you're describing when it happens. A soft reset for me when this occured fixed it -- and it hasn't happened for months.
But as we all know the same solutions don't work for all people with HTC devices.
I just had the same sort of problem. I've been using my TyTN for several months now under Dutty's WM6, and only just flashed Schaps 3.60 a few days ago.
It worked fine the first couple of days, but now I'm having the dreaded 5hr battery life too.
I had had that a couple of times before, but it was always related to some software, and a soft reset would cure it like Doom Tints said above. The problem is that here, either this or a power-off and reboot doesn't change a thing.
It's clearly a software problem too. I use UpTime Meter from AE, and I can see that the PocketPC simply doesn't turn into standby mode, but only deactivates the screen. In UpTime, the power on time will always be equal to the time since last charge, which means the PocketPC is on all the time. In that case the 5h battery life makes sense.
Would there be a way to find out why it doesn't enter standby mode (which software blocks it up), or force it into it? It would be good to find something as I'm nearly sure this is the reason for most if not all of the cases of short battery life we see around. Without having the meter there's simply no way to realise that the thing just stays on...

Your good man, Phone has been charging for about four hours and it didnt go up more than 40% so I unpluged the phone and turned it off and on and then it went up to 80% and now its recharging it again. Thanks

Since I had my hermes, a few times it would get very hot and discharge the battery, and I assumed I was turning it on in my pocket and running a program. But now it does this continually. As soon as I take it off the charger it discharges and gets hot. This even happens if the phone is powered off.
I have borrowed a battery of someone else and the same thing happens
I have also hard reset it and have nothing installed extra, so it can not be software problem.
Must be a short circuit inside the phone? Does anyone have any ideas? I can't send it back as it is a Cingular and I live in the UK and have no support contract.
Thanks,
Mark
I managed to investigate and find the culprit - A2DP Toggle in my case. Whenever its Today plugin is enabled, it will prevent the phone from entering standby. Deactivate it - no uninstallation needed - and it returns to normal. Weird as it had been working perfectly for about a week, and I haven't done any change when it started acting weird.
Now it kinda defeats the plugin's purpose if I have to deactivate it everytime...
@simkin: If it drains the battery even powered off completely that's most likely a hardware problem. Does it happen too if you remove the battery and put it again without turning the phone on (as opposed to having the phone on and turning it off with a long press on the the power button)?
There could be a slight chance that the phone actually starts booting and gets stuck there draining power. As a last solution I'd try flashing it with a different ROM, but if that fails it's most likely a hardware fault.
I'm having battery trouble too, I switched to WM6 with a full battery that lasted for about 24 hours and it became 7-8 hours, so I switched back to my previous ROM and Radio ver and it still says I only get 7-8 hours average, I'm gonna try to hard reset it on more time, and then i'm just gonna try a new battery.

After 100 days HD couldn't turn on Need Help

After have Touch HD for 100 daysI, have got a problem with it, it is about battery charging.
When HD turns on, it shows battery is low, then HD turns off automaticlly.
I tried charging battery with AC or USB, the Charging light is on but after hours, when turn on the devices it still shows battery is low, then turns off.
I changed a battery, it goes well, the device is on with all the fuction running well. and the previous battery is working after change the battery again. and it shows the battery is 90%.
But after a day. the problem is back again. and this time no matter what battery I changed, it still shows battery is low. and won't charge. even with the full battery the problem is same.
If you have the experience with this, please I do need your help.
BTW, The rom is from the factory.
Maybe the battery is fine, people have experinced problem with the actual charger. Have you tried charging through the computer?
Yes, I have tried charging with Computer, AC adpator and even Only charges the battery.
But the problem is not solved.
I suspect the HD's battery chip which manages the battery charging maybe broken ( if there is a battery chip)
Disconnect the HD from USB/Wall outlet. Remove the battery. Short circuit the pins in the HD battery compartment with a wire/metal piece. (never short the battery - it may explode!).
This helps in most cases for this problem. If not then warranty is the way to go.

Phone does not charge!

I have tried my PC and the mains charger, the LED cycles from orange > off > green > off constantly, the phone shows it is charging but the battery keeps decreasing.
Only 30% left to try and find a fix for this, hard reset doesnt help!
Any ideas?
Same problem HD
I had the same problem with my HD ages ago (before HD2) I reflashed the rom and that fixed the problem. The other cause with a HD2 can be a non genuine USB-micro cable I used a Nokia and although the yellow light came on it never charged. I found out that the wire configuration in the nokia cable is diffrent to the HD2.
Hope this helps

I have the same problem which started after i got a desktop charger.
At the moment I just switch to the spare battery that is in the charger.
I am currently searching to see if anyone else has had similar issues.
Of course I have loaded an official rom , just in case anyone suggests it but will not do mtty till I find evidence it helps.
lakeman
Strange, the only thing I could think of is the option in the battery screen to prevent the phone recharging when plugged into a PC - I have this ticked myself as it's not good for your battery to keep putting it on and off charge. However, it should still charge when plugged into the mains.

An update:
the non genuine battery may be the issue
I checked its capacity with htc tools and it seemed fine but needs to be fast charged in the desktop holder.
Anyway thats my theory so far.

Thanks, I thought of this but sadly not so simple.
The problem was that the middle pin of the battery connector was slightly bent and just needed pushing back into place. I suggest you all try it as a search of the forum showed me its a common issue.
it only happens for non-genuine battery. just leave it charging over night. or get separate desktop charger for the non-genuine battery.
Similar but different problem...
Battery is genuine as is the USB lead and charger.
Phone is flashed to 1.66 factory Rom , unlocked via unlock code
Had phone for 3 weeks and no real problems , only ever charged on the comp/car via usb. On monday morning the battery was at about 8% so i dug out the mains charger for the first time to give it a fast charge by the time i was ready to go to work the battery was at 30%. On the 2 hr drive i left the phone on charge in the car.
On arrival i checked the phone for messages and it was frozen , i took the battery out and replaced it and the phone fired up with 8% charge.
When i picked the phone up after 2 hrs on charge in the car the bottom (between battery and usb slot was VERY warm.
in the office i put the phone on charge on the mains and no light came on , but the phone seemed to stay at 8% and the back below the battry got warm very quickly.
eventualy after lots of messing about the battery is dead , charging does nothing except mae it very warm.
went into the local t-mobile to get a new battery , they didn't have one but the girl in the shop had a hd2 so we tried her battery in my phone, phone fired up , but still woldn't charge.
Last desperate move i reset the phone to factory settings , still no charge.
Only 2 things happened to the phone prior to the charging issue
a) I activated Microsft Myphone
b) I put in a 16gb mem card
Anyone have any ideas what to try next ?
Return your phone for repair...
yeah its looking that way , just on the hope i missed something

[Q] Critical battery icon showing when powered on.

I left my phone charging overnight via the wall charger. Battery registered at 1% when I started the charge.
When I woke up this morning I had a large low battery icon on the screen and the phone won't turn on. I disconnected the charge, tried charging with another charger but everytime it shows the SAMSUNG logo, then the large low battery icon.
I tried removing the battery, cleaning the charger port terminals, swapped out different USB cords, everything but a hard reset.
No matter what I do the phone will not start up.
Has anyone experienced this before, or possibly no how to resolve it?

Happened to me several times (on both my focuses Rogers and AT&T), and I came to the conclusion it's a bug somewhere in the phone or the battery. I'm not sure exactly where the problem is (software, hardware) but I can tell you how I fixed it.
What happens is, the battery is almost depleted, it actually is 1%. The phone incorrectly reads that thinks it's charged fully and doesn't allow further charging the battery. So, you're not able to charge the battery correctly.
Now, as I previously stated in some other posts, I recommend having a standalone charger (Samsung i9000 ones are compatible are very cheap) as well as a secondary battery. The depleted battery gets charged fine in the standalone charger and when it passes 5% charge, it can be charged fine (again) in the phone.
This doesn't happen often, I believe it happened 5 times in more than 300 charging cycles (2 phones x 150 charges, I have them for over a year) so it's not that common.
I also found that it *may* work if you charge the battery in another phone.
As a general thumb rule, it's important not to leave the battery to completely discharge, and connect the charger/usb when it reaches about 40% (when you can, ofc). Please refer to my post here to see how you can preserve battery life.
