Hi everybody,
I almost always managed to find answers on xda-developers to problems or wishes I had when tinkering with my phone.
Unfortunately, I haven't been able to find a solution for this one and hence my first post:
I always keep a fully charged spare battery with me just in case I run out of juice and I can't recharge.
However, when I exchange the run down battery by the full one, my battery status doesn't change and the phone switches off after a short while.
So far the only thing that works is briefly plugging in the phone with the replaced battery in it which will update battery status to 100% charge.
Obviously, this defeats the purpose of carrying a spare one around.
Is there a way I can force winmo to reset the battery status or another way to resolve it?
I don't mind if I have to rummage around in the registry if necessary.
Thanks in advance.

tat is the case with some batteries.. i have 3 batteries and only 1 that is acting that way.. all u need to do is carry a usb plug.. just plug it in when u are at work or anytin just for 30secs it will update to its full status.. or u can buy another battery so u get at least 2 battery that works..
Thanks Cutefox,
That sounds like a simple but effective solution.
I will try it next time I replace my battery.
the weird thing is that it does it with Ericsson's original battery.
Nevertheless, I may not always have such a plug on me.
There must be a trigger though when the USB plug is inserted.
If we know how WinMo recognises a USB plug has been inserted (maybe a switch in the registry), we can fool it into thinking it was inserted, and I wouldn't have to carry a plug around.
Any other suggestions?

nah.. its not about the plug.. its more of the voltage.. there is a trigger sumwer in the battery that switches on when you charged full. the thing is if you use a non-official charger like battery clip charger which im using, it is not as smart as the official SE charger/usb plug.. i think its due to the battery being charge outside of the phone too.. in the beginning it was always doing it so i thought my battery is faulty.. but after awhile, even charging it through the battery clip charger i sometimes come up with full battery.. so i got no idea why this happen.. another thing that could help is once u boot the phone up and it says its empty battery/low battery, do a software softreset.. that sometimes trigger the switch and turn on the true battery power for me.. only on stubborn times that i need to use the usb plug.
Thanks Cutefox.
I understand that in this case WinMo can't change the battery status without at least a minor external charge.
Let me ask you this. What eventually switches off the phone?
Is it the battery's power management chip that cuts further power to the phone, or does WinMo cut the power when the battery status reports 0% remaining charge.
In the letter case I could write a script telling WinMo to ignore the power warning for a predefined time, which should allow me to reach a power outlet.
i never tried tat b4.. but usually if its 0%.. there are times when i used xperia for extensively heavy usage and it suddenly shuts off on me while battery is still abt 20%.. i cant remember if its this battery as well.. since i always bring more than 2 battery it does not really bothers me as i got another battery to sustain.. but from what i recalled is not the windows mob status report warning that shuts it off.. more of the battery power itself..
Thanks Cutefox,
I guess I'll have to get one of those penlite powered emergency chargers to kickstart my battery for now.
In the mean time I'll continue looking for alternative solutions and report them here if I find them.
Does anybody else have ideas?
excuse my curiousity, but how the hell do you guys get the phone to stay on while you swap the battery? As soon as I take my battery out, even if the phone is in standby, it loses all power and cold boots upon putting it back in and powering on...just wondering as it sounds like a more viable option now to carry a spare batt!

of course you power the phone down in the first place before you swap it. you cannot swap it while its on. well u can and it will turn off but that is pure stuffing up the phone. never do it to any fone as per advised by a sony ericsson repair guy as it stuffed some of the IC chip inside. always power down before changing battery likewise any other electronic device..

After several cycles on WP7 the batt was fully drained and now it won't charge (charge LED goes on for few seconds and then goes off). It won't load either, just switches off on DFT screen. Batt is standard.
Guess it is critical not to allow batt to drain fully on WP7?
Is there any solution to this?
Thanks for any ideas.
Had a similar problem with Android...battery drained completely and wouldn't charge. I solved it by cutting the end off of a spare USB cable, removing the battery, and charging directly from the cable (red wire to positive/black to negative). After about twenty minutes I put the battery back in the phone and it booted Right up. Or, if you have more sense than me, you could just pick up an external battery charger...I'm just the hack apart a cable and do it caveman kinda Guy...

I can confirm a similar experience; I thought it was worth trying the fully-drain-then-fully-recharge regime suggested elsewhere on these forums as a means of extending battery life, which does struggle a bit on WP7.
The fully discharge bit was easy, but it is worth everyone bearing in mind that magldr - as advised, I believe - will not allow the phone to charge. As a result, I was getting into WP7 (just) only for it to almost immediately shut down. But it was at least doing a small amount of charging before it did.
After a sweaty fifteen minutes or so of restarts (I was having to take the battery out to force the restart as it wouldn't start on the power button), it decided it had enough charge to...well, charge and all was well.
My suggestion would be not to risk going beyond the critical warning WP7 gives, at least until magldr is able to offer charging.
Almost the same issue here, without having let the battery fully drained...
I can't charge my hd2 anymore.....if it's turned off.
But, it Can be charged if wp7 is running! I don't know why...
I had This issue when I received the phone. It took me a whole Day to charge the battery the first time : orange LED turning off after 10seconds (HD2 switched off or in wm6.5
Once the led is off, can't turn the phone on or charge it again until I remove and put the battery back.
It was in summer so I thought the phone was too hot, so I cooled the battery with a fan, replaced it, retryed... At least 10times, and it finally charged.
SO weird, I'll test This again with wp7, who knows?
I am wondering whether it is some kind of magldr bug?
I'll try the trick with the cable directly to the batt. It is not very practical though if you drain your batt, where there is no access to spare cabling.

This should be put into the sticky rollup thread for people who have let their batteries drain.
Why dont you do some pics bud and create a topic?
I am cutting the cable as I write. Will take some pics.
If your battery drains completely, just remove it, replace it back. Without starting the phone, connect it to your PC. start and enter the bootloader. You'll be then able to charge. I did it like that last week.

Running cable directly to the batt is confirmed to work. Just revived mine with this trick.

Less of a bug and more of an unwanted side-effect of having this excellent capability, I think. I seem to recall that the developers are aware and looking to see what can be done.

I guess it is possible to completely drain the battery, in which case this won't work. But if there is some power, removing the battery and replacing it should kick the phone into life for long enough to do this. This was going to be my first try if persistent rebooting hadn't eventually worked.
having this problem and definitely charging below the amount...
i cant fully charge the battery as well
Like I said, if connected, but not started, to your computer, you'll have enuff time to start it then and entering the bootloader, of course, you gotta be quick for this to work.
If it doesn't respond, don't laugh, confirmed to work, remove your battery like explained and put it for some mins in the fridge before replacing it (it's only chemistry playing here, somehow better than cutting a USB cable in 2).

"storing them in the freezer might be more practical. These kinds of batteries lose their charge after a few days when kept at room temperature. But they'll retain a 90% charge for months if you store them in the freezer. Just like alkaline batteries, you'll need to wait until they've warmed up before using them. However, this isn't a problem when you need new batteries for your digital camera or other electronic gadget. "
I suggest you to be more polite when answering and learn your lessons before posting!
I finally made a dual boot Android/WP7.
At first, Android said my battery was fully charged, just like WP7, which is totally impossible as I used MAGLDR to format the SD card (wp7 & android partitions) and that it took me almost 1hour, without any possible way to charge the battery while I'm in bootloader mode.
But when I turned the phone off, plugged into the wall.......TADAA It was finally charging, with phone turned off
So, it seems that dual boot may be a way to solve this issue

You're arguing against yourself here aren't you? Cold may be fine for storage but you need heat to coax a little more power out. You even say 'you need to wait until they've warmed up before using them'.

Wrong idea, sorry guys.
I thought that HD2 was charging since I installed WP7 and Android in Dual Boot. But it's a fake : if the phone is turned off, and that I plug it, the orange led turns on. But that's all, even if I unplug the phone, the led remains turned on !!
And now, Android as well as WP7 are telling me that the battery is fully charged but I'm sure it's not even 50% full.
So we all know the major problem with the WP7 roms.
You can not charge your phone when battery is completely drained!
Now here is the solotion. This requires no apps, no mods. Just your own handeling!
So what to do when battery depletes?
1. Plug your phone into a powersuply.
2. Turn on the phone and keep the power button and both volumes buttons pressed. (this is called a hard reset.)
How to hard reset HD2, view the first 17 seconds. Ignore the VolUp!.
3. You will receive an message saying:
''This operation will delete all your personal data, and reset all settings to manufacturer defailt. Press VolUp to restore manufacture default, or press other keys to cancel.''
Click to expand...
Click to collapse
4. Do not press anything. Let your phone be for a couple of minutes. I keep my phone laying for a minimum of 10 minutes.
You won't see the phone charging (no orange light in upper left corner)! Believe me it is!
5. After 10 minutes restart the phone. If ''press any other button to cancel'' does not work. Take out the battery, keep battery out for 5 seconds. Restart phone.
6. Phone will start. After windows phone loading screen you will see the phone is charging. If you kept it on power. If not, you didn't follow my instructions.
Tip: to avoid battery drainage!
When the phone is making the bleep noice warning for critical energy level, turn off the phone and keep it at a warm location. Ideal is to take out the battery and keep that to as warm as possible. Batterys barely drain when they are in warm enviorments.
I am not responsible to any damage done to the phone!
I done this multiple times, all times it worked fine for me!
If it helped, Thank me and leave a comment
when i'm on the road there is only one warm place i could think off, besides my armpits...
but your method works, have faced it once.
Thanks for the conformation.
To bad the HD2, is kinda big... doesnt sit that well.
magldr works as well
whats not clear is if the battery controler is in use with this method, so be warned, dont leave it too long, if you charge it for no more than an hour it will be ok
mains power adaptors usually give out 1Ah, take in to account that the screen is on full, this should give you around 700mA, more than enough to get in to windows to charge propperly
USB charge will be half that, most USB ports only give out 500mAh so an hour will give you approx 200mA again, thats enough to get you in to windows
Overcharging a battery can have some side effects, firstly is reversed polarity, meaning it wont take as much charge in the future, or it could heat up a lot, which isnt good for anything, the life of battery or the device its self.

That is true, but I recommend trying it for a minimum of 10 minutes keep it on charge. and as soon as windows pop on it recharges normally.
And didnt knew magldr did the job as well, the only problem is if you deplete it to badly it doesnt go past the HTC screen in the beginning.
all this is completely unnecessary.
easy fix solution:
1. Pull the battery out and USB cable out (if connected and charging)
2. Plug the USB into the phone and allow it to charge without a battery (it will not, duh!)
3. Put the battery in while the HD2's connected to the USB charging.
4. Observe that you can boot all the way back into WP7.
enjoy.

Well thank you. Although I am not such a big fan of taking out the battery when its not needed. I mean the change is short circuits with the connecting points when taking out, when powered or putting in when powered it larger. Now I heared from a comment above that MAGLRD does the trick as well. Now that is far more easier then all the others given above, Yours and mine
good tutorial on this. I cant believe the battery wont charge when dead thought this was a faulty error of the phone.

theres 3 methods on here,
bootloader charge
magldr charge
remove battery charge
all three will benifit frm heating up the battery, do not cook it, or it may blow up
there is a 4th way but i dont recomend it unless nothing else works
take a usb cable mini or usb printer cable
cut off the end connector
strip back the wires and seperate them all, you want the red and black ones
make sure all the wires cant touch each other, cover the 2 unused wires with tape i
then connect the black wire to the (-) negative and the red wire to the (+) positive
tape them in place
the 3rd contact point on the battery isnt used in this method
finally connect the other end of the usb cable to the computer
dont leave it too long and when disconnecting remove the computer end first

It bypasses the system somewhat. Don't know what happens when battery is entirely drained, but it is worth a try.

Thanks for this timely post Lemonspeakers. completely drained the battery listening to music on loudspeaker and didnt hear any warning. Couldn't hard reset then checked this thread.
On putting in the battery after charging the empty phone, the screen kept cycling between mgldr and HTC splashscreen so booted into sd android and the phone is fine.
I assume I didnt charge the empty phone for long enough (30 secs), I didnt warm the battery and I suppose I could have left it cycling until it charged up a bit more.
Thanks again

That might work.
Otherwise maybe a phone repair shop, there is equipment that can charge your battery outside an phone. An emergency charger its called if I am not mistaken.
you could inform there.
its showing symtoms of it bring bricked. cause it doesnt charge, it doesnt turn on without the battery, and yeah conclusion is that its dead!

Better not do hard reset on the Android, can not help but bring you trouble ... to the charge I had the same case on CM 7.2, after a few reboot is to be changed do not know what the problem was, the developers are working on it, read forum you will find lots of information about
"i can hear a strange noise coming from the charging kit"
I would not use it, it is safer to be charged via USB cable.

Thx for reply. I don't think it's an android ROM problem. I had the same problem when i still used the wm 6.5
here's a solution
Flash Back to Wi-Mo and Check Setings\System\Power\Battery -Do not charge the battery if the phone is switched on and connected to a PC.
How do you know, that the phone is not charging?
The state of the LED (red/green/off) is changed by software (WM/Android), if the device is turned on, while the charging itself is controlled by hardware only.
You should check, if the phone is really not charging, while its turned on. Just ignore the charging LED and monitor the charging state of the battery after an hour, after you started with an almost empty one.
Best regards
@stahlnase, you're right when it comes to Android, but (windows phones) have software to control the charging. Something else;although we have through the nand installation erased entire phone, there are still some Wi-Mo "things" in this case battery setting or GPS was also associated with a Win-Mo settings. Regards!
I'm still not convinced, that the battery doesn't get recharged, just because the LED is not on
But you made an important point about enabling charging, while being connected to PC. Since demian12 is not using the HTC USB power supply, the device might "think" it is connected to a PC instead on a pure USB recharger. I believe, there are differences in the wiring of USB connectors to determine, if its a power and data plug or power supply only.
Regards.

Because your battery is completely empty ... it is necessary to leave some time (5-10 min) to charge, ignore charging indicator, the battery is charging! After ten minutes put the battery out / in and start a Phone.
Go to: Setings \ System \ Power \ Battery.
And Unselect option: -Do not charge the battery if the phone is switched on and connected to a PC.

Strange isn't it?
Any ideea?
If you have a good HTC charger and battery doesn't charge after you reseted windows to factory default, then your problem is hardware related.
Of course I have some ideas, but do not have time until Monday to deal with anything. Sorry. I have a suspicion that Nokia charger burned your phone. Of course, should be checked, maybe is a bug in the Android battery driver, and with the help of a trick to make the jump and put everything into place. either way, do not give up, try again and again to turn on your phone.

Hey guys,
I noticed this yesterday my Nexus 4 (running PA 3.6, franco milestone 1) shut down at 30% charge. I went home and charged it (it showed 0 when I started charging it) to 100% continuously.
Today too the phone shut down when it was around 32-31% and now charging has again started from 0%.
What could be the issue?
I have tried the battery calibration app even though I know it does nothing.
Any ideas?

I have been flashing nightlies merrily on the Nexus4, never had to recalibrate the battery, though it sounds like your does need that. (I had a Desire HD before this, and it was very sensitive to errors in battery calibration)
How about if you charge the phone fully then either reflash the ROM or flash a nandroid backup you've made? Either of those options will overwrite the battery stats file - if that's the problem.
It could be that the chip in the battery is malfunctioning, ie a new battery could be needed, but that sounds much less likely

Okay I'll try reflashing the ROM when I'm at a 100%, I know deleting the batterystats.bin file doesn't do anything but I did that anyways yesterday, but it seems it didn't fix the calibration issue.
Any other ideas I could try while I charge my phone to a 100%?

Hi, @paul c, I would like to inform you that my phone's discharging just fine (charged it to a 100% last night and it's currently at 48%, I didn't reflash my ROM but I did reboot it once. I also haven't charged it since then)
Could you tell me what's the minimum and maximum battery voltage? I am guessing that the max voltage is around 4200mV but what's the minimum? Also, can we calculate the REAL battery %age from the voltage that is displayed by apps like DashClock? If we can do that could you tell me how/what formula we use to do that?
I know I'm asking a lot of questions and I would really appreciate any help here !
Thanks!

Okay the phone died at around 34-36% again, I'm gonna leave it to charge over night, I'm still stuck !

Worth a try - charge the device to 100%, turn it off, open the back case, disconnect the battery flex cable, reconnect it ... try now.

Hi, I'm no pro when it comes to opening phones However I'll check out a video on LE55ON5 tomorrow on how to do it. Thanks for the tip.

I didn't open the phone but i'm taking it to a LG service centre today, no soft methods have worked so far

Hi,
I was inspecting the battery's voltage/charge the entire day today and I realized that at around 36% the voltage went around 3000mV (3100mV, Nexus 4's battery is rated at 3800mV and it maxes at around 4200mV). After that when I plugged it back in and turned it on it started charging from 0%.
I think the battery is at fault.
Is there any fix for this which does not involve replacing the battery?
Thanks!

Unfortunately this didn't work for me. I tried charging through the night and then discharging it completely and charging it completely again. I also tried deleting the batterystats file (even though I know it doesn't do anything)
So what do you suggest I should do? Get the phone replaced or get the battery changed?
I live in India and the phone is from Canada, so replacing the phone will take some time but I can get the battery replaced for around $20
Also my nexus is also showing +ve mA values while it's not charging, and the values are absolutely crazy, +268, +168, +1171 (in batter monitor widget)
Please tell me what I should do.

So you tried to disconnect the battery cable and reconnect it?
When you open the back case did you notice if the battery looks bigger/inflated? Maybe you should replace the battery.

I didnt open it up, I was unable to separate the back cover from the front. But I've tried everything else.

Might as well replace it while you're at it. It's $20 on eBay OEM.

I tried doing as he did, but I wasn't able to open it, and yeah, I'll be replacing it first thing tomorrow. Hope it's not a hardware issue that needs the device to be RMA-ed

Okay, I got my battery replaced, drained it to 0% (after a full charge) and going to charge it completely by the travel adapter that I purchased from the service center.
Attached are the pics of my old battery, I don't know if you can see it but it's swollen. If I recall I used a nexus s' charging cable to charge the phone from a computer and it was charging like AC (my kernel usb fast charge was OFF) and it also never detected my phone in the explorer (Windows)
My problem's solved now, it was a battery issue for me. I upgraded to PA 4.3 in the process by the way
So I guess I'll stick to my regular micro USB cable and charge via the travel adapter whenever possible, thank you everyone for your inputs!
