I've had an o2 mini s for about a week now and i'm pleased with it on the whole. My only real concern is battery life. My mini seems to drain much quicker than by xda 2 s which I had before. I seem to drop about 10% in 1 hour 10 mins and that's just a few calls/txts and minimum fiddling.
8:20 100%
9:42 88%
I've dropped all the o2 software and don't have any tricky 3rd party apps installed only;

I've read quite a few posts about battery life being good on this phone but i'm not seeing it. I'm still in my 14 day cooling off period and i'm considering sending it back for a replacement.

Is Wifi off, bluetooth off. Do you check your email every ... minutes over GPRS?...
With email checking every 10 minutes my qtek battery last at least 2 whole days.
wifi/gprs/bluetooth all off - not used today
Just phone today - maybe 12 calls.
Time now 14:21 battery at 61% !
Now i'm worried ......I reckon i'll be down to 30% by this evening.
16:32 - 49%
maybe there are problems with these batteries i had problems with charging the battery it didnt seem to show correct level, sent it back for another unit
17:26 - 38%.
If another goes we'll be up here all day.
My battery life seems to be utter rubbish every time I charge my MDA Vario over the USB link. I can go to bed with 100% battery and find it dead by morning. This has happened two or three times since I bought it on 5th November. Last Saturday morning I had the USB cable connected to download some music to my SD card with 100% charge at 10:00. I played music for about an hour through the supplied headphones and by 13:00 I was down to 50% battery. By that evening I was down to a few %. I've read reviews that you you should squeeze about 10 hours of continuous music from this thing on one full charge so an hour of music and 7 hours of standby/sleep seems pathetic.
If I charge using the mains charger and sync over Bluetooth I get a standby battery life of about 5 days. Obviously that is shortened with use so in practice I am charging it every 2-3 days (no point starting a day with only 20% left!).
I have no idea why USB charging is completely hopeless. I have tried soft resetting or closing all active apps after charging, to make sure ActiveSync isn't actively running and causing a drain (just as you are advised to with a Bluetooth sync) but that seems to make no difference. USB charging is rubbish. Mains charging is the only way to go, IME.

I confirm USB charging IS rubbish. The reason seems to be that the power available out of that conector on a PC is not enough to charge properly... I had the same issue with BA and Himalaya...
Answer: get a USB charger / car charger that can deliver 1A minimum.
BTW I found a craddle for the Wizard in Dubai @ Plugins. It comes with USB port/cable + power adapter. Works like a charme.

My C500 Did that when I had it Plugged in the Front USB ports on my case, I normaly had it plugged in to the onboard USB at the back of my pc with a usb ext cable so I could have it on my desk but I went off to a lan party and when I plugged everything back in I put my USB cable to front usb port and found it was Discharging my Battery instead of charging it, got my usb in Back port all is fine again now
Maybe you have yours in to the front USB port or non onboard port?
I use a laptop, which only has two USB 1.1 ports but they each supply enough juice to power a USB ADSL modem (not that I'm using one of those these days), which is more than some PCs will manage and also my USB hard drive, which my Shuttle won't. So there is no lack of power from the USB ports on the laptop.
Of course, the USB spec only permits a maximum current demand of 500mA so any equpiment expecting more should not be using USB for its power supply. In any event, the phone does charge from the USB ports, albeit very slowly, but eventually the orange charge light does go green. So my situation is not one of discharging instead of charging.
I've just swapped my ROM from Vario to k-jam so I'll see if that makes any difference to the performance. I know it's given me 802.11g, which was missing before.
I had an M500 briefly (Magician) on Orange that had very poor battery life, it was one of the reasons I ebayed it, gave the contract sim to my wife and started a cheaper better value T-Mobile account with an MDA Compact, which
had better battery life. Typically overnight after a full charge the Orange unit went down to 75% and the T-Mobile one was at about 98% on standby.
My Vario I have now, my other T-Mobile account has very good battery life and charges very well off USB. If I sync it in the morning whilst reading my emails and stuff, let it charge USb for about 25 mins, it'll be full and by the night it will have dropped down to about 80%. This is with about 30 mins of calls, about seven or eight emails sent/received and maybe 15 mins with WIFI on.

I can't remember for sure where I got the k-jam ROM ( I think someone saved a copy somewhere) but try here - ftp://ftp.clubimate.com/ - and then save file K-JAM_WWE_1010903_106_10110_ship.exe
That is a self installing upgrade that includes the whole k-jam ROM and k-jam extended ROM files.
I don't know where to get a Vario ROM from. I did back up my own copy (I hope) but the method is a bit whacky and as I only have a 1GB mini-SD card my ROM backup image is 1GB because the only way to secure the image is to dump the whole card to a file.
Before you go playing around do make sure you have your own backup of the ROM or if not the whole thing then the Vario extended ROM files at least. I'm using the k-jam ROM with the Vario Extended ROM.

Hi,
Is there any way to disable USB charging? I didn't connect USB very often since it will charge automatically and I don't like the battery be charged very often. It might kill battery soon. I like to sync with bluetooth; however it is much slower than USB. It's amazing if there is any tool to disable USB charging. Because it will sync fast and will not hurt the battery. Thanks for the suggestions in advance.
Cheers!
Michael

You are thinking of older batteries such as Nicads. Topping up often does not hurt Lithium batteries, in fact it's better for them. Their main enemies are deep discharge and heat - and that's exactly what you're subjecting it to by letting it run flat, then charging for hours to get it back to max.

Dear Ineedtoys,
Thanks for the reply. I understand that there is no so called "memory effect" on Lithium battery; however when I checked the battery spec, I always found that there is a "charging cycle limitation". For example, a specific battery claimed that it can be rechaged 10,000 times, then very USB charging will be counted also. It will reach 10,000 times faster. This is my concern. I don't know if this is right or wrong. Can somebody help to clarify this?

That's true. It's the same with Notebooks. The more you charge it, while it's in use, the faster the battery gets "killed"!

Answer my own question.
I am quite sure that the USB charging can be disabled since I used to see the config on a HP device. I also believed that this can be done by 'registry' since it is Windows tradition. I finally found it after a short study. Please go to
HKLM\Drivers\BuiltIn\usbfndrv
and change the
EnableUsbCharging to '0'
then
soft reset => Bingo.
Hope it helps.

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?
Mike
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.
Mike
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...

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.
Hi guys asked it once before in battery section, but no replies.
My HD doesn't charge auto, when I press the on button the battery charges for 15 sec. tried a new battery same result. I know it Physicly charges, when I charge the phone by pressing the on button a couple of 100 times (really 100x) I get 1% charge. So don't say 'HTC phones only charge when on', cause I know.. Tried a Hard reset 2 times no luck. meanwhile my batt. is dead. So I can't try other firmware.(need 50% charge min)
(chargers are fine)
In short, anybody ever heard of this problem before with other htc models/HD ?
Physicly it charges, so would a firmware change help?(then I need to get a standalone charger/new battery with charge).
My last option is to bring it to HTC but that would take a month
Sorry for number of words on this lazy sunday.
Update - firmware update doesn't work.. next is radio....
no ideas anybody?
Hi,
Unfortunately I dont know much other, then charge the battery in another HD up if available (maybe u can ask in a telephoneshop or so) and then test the Firmware changes.
Is the same if you charge it via PC/USB?
thx for the reply, did just that, changed Rom/radio, official and dutty's rom's, no change. No problem sync. have atleast 3 usb chargers none of them work. When connected to usb cable 2 lights blink 1 green 1 amber one after each other. just like a new message/ low battery even when battery has 50% I get the same light patern, (this is a new battery).
The thing is when the battery is completly flat it stil charges for 15 sec then it turns of. So when I charge it 15 (x15 sec) times or so I'm able to turn the device on again. But when it has (some) battery power the lights start blinking again and I'm completly unable to charge the battery.
The phone is almost 2 weeks old and charged normaly until I checked the "don't charge when connected to usb" option in the power menu. ??!
Then I think you wont get around, to send it back for repair.
have you tried to charge it with a wall socket or is this only when you usb to pc charge??

I never charges, wall/usb doesn't matter.
I just used another HD battery to restore everything to default, So I'll guess I'm taking it back..
Thx anyway.
exact same problem
Did you get anywhere with this problem? I have been strugling with the exact same thing... I have tried all the same things as you, only sometimes it seems like it might be the battery contacts.. I havent been able to consistently get it to work but sometimes if I firmly press the battery against the contacts it will behave normally

Nope tried the contacts but they work fine, battery just won't charge, do your light also blink? (on the power button).
I haven't found any info on the web?!?:S
Problem is solved.. had to be sent back to HTC for repair, it took less then 2 weeks (door to door) so that was pretty fast. They swapped the mainbord, so I got my 'old' phone with a new imei.
So don't waste your time with software up/downgrades. It's a hardware problem.
I had a very similar problem.
Once my battery died some app hung system all night.
No charging at all wall charger and USB 1 day each and so many manipulations. The indicator blinks momentarily and then nothing. I didn't try (didn't know) the key presses like Dogtag. Did a hard reset still nothing...
Then thought about charging the battery with external (Lion) charger before sending for repair. I also shorted the battery compartment pins momentarily. To my pleasant surprise everything back to normal
So far no problems after that though I never drained my battery to zero.
Looks like something to do with corruption in battery calibration data - may not be in ROM?? who knows??
fantastic. can u elaberate?
hey Cragee
I did't understand what u did. Can u try to explane it to me one more time?
I'm realy excited about a posible soulution
hooray

Only two things I did can matter -
1. Charging the battery after taking it out (with a battery charger*)
2. shorting pins in the battery compartment after taking out the battery. (Warning: not on batteries)
Don't know which of the two worked.. No harm trying both anyway.
* U need a Li-ion battery charger - else invitation for trouble including fire and explosion.. These are available in electronics shop at a reasonable price.
Short-circuiting the battery pins... seems to work
I had the same problems with my Touch HD the last few weeks:
- stopped charging after a few seconds
- didn't charge at all (nor the wall nor the computer method, on or off)
- well... it charged sometimes but randomly, keeping it on a wall charger (on OR off) for a night could bring it back to 20% and then rapidly back to 0%
- no charging indicator in the screen while turned on
- blinking orange and yellow (?) light even while turned off
- charged almost never to full and 'jumping' from high to ultra low capacity when turning it on & off
So before bringing it back to the store i tried to short circuit the battery pins as suggested (while the battery and charge were unhooked) like the thing you would do to clear the CMOS memmory of a PC in the 'old days'
And for now it seems to work, at least the charging icon is back online!
I'll keep you posted on longer term results!
Update: I switched to the wall charger and the HD died again??? Now it's back on the computer and it seems to charge fine... why????

When u say "shorted the battery" do u mean, turnoing phone off, taking battery out, connecting the 3 battery connectors with a wire for a few seconds?
....so what does shorting mean??

I thing so. You should circuit the pins WITHOUT battery. In any other case it may occurs damage on the telephone
Dogtag is right... it's defenitly a hardware problem
As posted before...i had the same problem with my touch HD, charging was a pain or sometimes seemed impossible. The phone was repaired twice.
-First they replaced the connector - no succes.
-Second time the replaced the motherboard, and everything was solved.
So imho it's the mainboard of some machines, i still wonder if it's a factory problem or a 'fried' chip of some kind after a bad charging procedure? Bad USB car charger of some kind?
Strange Question? When my battery dies in the past I used to just plug it into my pc at my desk... DELL T5400... and charge the phone up again.
Though lately I have been using a hard-drive cable and I can't seem to recharge my phone on any pc??
Though I can pretty much download all the information from the phone??
I do have the dutty rom on.... though I don't think that would effect it?
Does any one have any ideas?
Under "Settings -> System -> Power -> Battery",
you find the option "When phone is on, do not charge the battery when connected to a PC".
Perhaps its activated?

If you have let the "battery die" over and over you could well have sent the monotoring circuitry below the charging cutoff point which is voltage dependant.
If the battery still charges from a wall outlet then this is more than likely the case as your wall charger will be rated at 1000mAh whereas the USB port is only 500 mAh max and if you have other devices plugged in at the same time it could well be a lot less and this will now no longer "start" the charging process.
If all this is the case then you have trashed the battery.
If not then charging through the wall socket could partly recover the situation, if you are lucky!
When (if) you get a new battery then keep it on constant charge (wall outlet, USB, car charger, external battery pack etc,etc) as much as possible and try to avoid a full discharge.
You guys are great
Thanks Guys that helped a lot.
I have always been scared of discharging the battery completely, Thank pa49 for confirming that.
I found the default setting for the battery was what jkolner said, Thanks bud .
I appreciate the help
Hi all, there is a way to turn off the charging function when using USB ,
1-install FdcSoft TaskMgr from here
dotfred.net/TM/FdcSoft_TaskMgrv3.3_WM6.5.cab
2-go to Devices--->$device\BAT1(BAT1 and stop this service
3-thats All
To Use charge restart this service
hey thx for the tips! but after stop the service my o2 keep saying batt low...
Is there any reason why we would want to turn off this service?
I heard that it keeps your battery in good shape

I'm not so sure about that... I've always charged both my O2 and the O1 before through usb and the battery has always been fine.
Actually, I even noticed that charging through usb takes longer but once it's charged it also lasts longer (this happened on the O1, haven't made the same comparison on the O2 yet)
Dunno if plugging / unplugging the usb cable too frequently can have some sort of ill effect on the battery life, but it's not like we're plugging it every 10 minutes is it?
Never had a battery problem with a "normal" usb usage and usb charging enabled so far...
Yes but not anymore

It's always good to drink all the juice so the battery don't develop a offline or fake "memory".
Also the multi cell assembly insde the battery praticly don't allow batery memory anymore.
Thx for the reference
Regarding battery life
Hi,
Actually, for a battery it depletes it's life every second. There is no way of preventing this But we can extend the service life. For example the most basic rules:
1-Do not charge your battery unless it is almost empty
2-Avoid deep discharging (this is not possible with a PDA coz it has an early shut down routine)
3-Do not overcharge the battery (also this not possible, coz there is a voltage limiter by hardware)
4-Do not leave your battery in a high temperature environment (for example in a car during summer, we are using chemical-reaction batteries)
the rest is do not puncture, do not short circuit boola boola boola
ok, finally while using your PDA with a USB charging interface, it should stop charging when the battery is full (Even my mother's old nokia doing this)
Plus, how much it costs for a new battery? only few bucks.. ehh.. (not for an original one ofcourse)
PDA batteries, in most cases, are 3.7volts (charging voltage is 5volts by USB) and 1200 to 1500mAh (for the ones who doesnt know what is "mAh": it is the capacity of the battery and it means if you pull for example for a 1300mAh battery, 1300 "mili ampers per hour" it will deplete. Some of my friends they are using 3.7V 2000mAh batteries while their PDAs supplied with 1230mAh batteries, thus, standby time goes up to a week. They are not using their originals ofcourse. I dont understand why manufacturers are not supplying PDAs with these kind of batteries by standart. Even a chinese made battery can be so efficient. (I am using a chinese one, my original battery is 1300mAh, i could find 1500mAh same battery)
I spoke to my friends, they are not charging their 2000mAh batteries via USB/charger while battery is in the phone. Because there is an internal electrical resistance of every battery. May be PDA's battery charging circuit get damaged! Because of this if you plan to use a high capacity battery, charge it seperately by using another charging equipment.
Finally when you want to sell out your PDA install the original battery (which you have never used before hehe ) and get a higher price
This might be some really big idiotic question, but what if the service is down and the battery drains and the phone shuts itself off, will it turn on by connecting the charger to the phone?
I ask this because with the service off even the real phone charger wont work (at least while it is on)!

I just did what you said, and now the device\BAT1(BAT1 completely disappear! How am i supose to turn it on again now?
And no, i obviously didn't delect it, i just stoped the service and it vanished from the damn list!
im very interested in this but how can you restart the charging service?
