I read in one of the discussions see that one problem identified in WP7 install on HD2 is no charging when the device is off. It is referenced as a maglard issue.
However, I am facing a completely contrasting problem. I am using an extended HTC battery and since the time I have installed WP7, the device does not charge while it is switched on. I see the charging icon blinking when the phone is kept on charge, but even after hours the battery status does not change. I unplug the charger and immediately the battery warning pops up.
However, when I switch off the phone and then keep it on charge, the battery does get charged up to 25% (guesstimate by seeing the battery icon after I switch on the mobile) and the orange led light is on. The led light turns off after 15-20 minutes and the mobile does not charge any further. Also, after this, when I try to switch on the handset by pressing the power key, nothing happens. I have to take battery out, reinsert it and then switch the device on.
It is making WP7 a very unpleasant experience for me so far. I have not yet activated the Live services on the WP7 install but I do not think this could be a reason for the charging issues.
Is this a peculiar problem or is anyone else facing this issue? Can anyone tell me why this is happening? Thanks a lot in advance for your help.
As far as I am aware magldr doesn't support the extended battery. I suspect it partially charges when off while normal batteries don't is that the ext bat has some extra control circuits for the extra bit but relies on the phone to charge the rest which itcant.
I wouldn't risk keeping a battery constantly so low charged, you risk damaging it or the phone. If you must stick with wp7 I'd flash back to Wm and give the bat a good charge every few days just to be safe.
Extended bat is not yet supported on WP7 so thats why its not charging.
You should either go back to 6.5 or Android until bat drivers are made for extended bat.

Hey guys.
I'm experiencing some problems with my Touch HD. When I get it to start I'm really happy with it and every program runs as it should.
My problem is the battery or something like that. I can have the battery power at 70% one second and the next the phone is telling me to either charge the battery or the device will shut down. I try to start it again but at the start screen it says Battery level to low, your device will shut down.
When I try to charge it the LED under the power button will show a solid amber light, telling me that it's charging, for about 7-9 seconds and after that it will either start flashing between amber and green light or just turn off.
I've tried having it like that over night and try to start the phone in the morning and the same message appear on screen, "Warning! Battery level to low! Your device will shut down!"
Read in some other post about someone who had a similar problem, but not quite the same, and that was resolved by removing the battery, plug in the USB cable for a few seconds, disconnect everything and then put the battery back in and start the phone. This works for me about 30% of the time. When it works the battery shows about 60-80% power.
I've tried a hard reset and I've tried to contact HTC without any success. Any suggestions from you guys, you seem to know almost everything there is to know about these phones.
Thanks.

Have you tried keeping the battery out for a day?
When I got my phone, the first 7 charges I turned the phone off and charged it all the the way up (to get the calibration accurate). Now the battery life is excellent, I can use it for couple of days without charging.
You should try returning the phone, seems it is fine software wise. Can you use the phone with the charger in? If yes, then there is probably something wrong with the battery or the hardware that is interacting with the charging.
I've tried keeping the battery out for about 24 hours but it didn't help. I can't start the phone when I have it plugged to the charger. I'm going to return it today and see if they can just exchange the phone in store or if they need to ship it somewhere to be repaired
Thanks anyway.
Sounds like a defective battery to me...
That's a good idea, better to get a new one.

switch off wifi, install Advanced Config, select all power management enabled
and try again. i also had the situation that my hd took 1550 mA. so the battery was sucked empty within several hours. now everything runs perfect...
Have exactly the same problem
I have exactly the same problem. One moment the phone works and charges fine and the next it shows irratic battery levels and eventually needs to be shut down. Following the shutdown you get the 'Battery level too low' message on startup, right after the Smart Mobility screen. In my case I think the problem mostly started when the phone was either just connected to a PC using the sync cable or when trying to top-up the charge using the wall charger. I also noticed that when the problem appears the plug symbol would appear (indicating it is charging) or sometimes not and then when checking the battery level, the indicators would actually go down sometimes losing 2 or 3 at a time until there is only 1 left and the phone says it needs to shut down. Pluging in the wall charger does not help as the LED indicating the phone is charging only stays on for a few seconds.
Now, I had many trials with removing battery, sim card, memory card or any of those in combination and sometimes these seem to work, but I think the key is the temperature of the phone. Every time I went to the car to drive home, where it was cold, the phone would start charging again, when just before that it would not react to anything all the time I was in the warm office.
I have now contacted HTC and am sending it to their repair centre tomorrow. Hopefully this is recognised as a fault and I will get a replacement. BTW, they arranged for a free courier pickup. Not bad, but the key for me is that the phone is being replaced as I really like the phone.
Update: Got a replacement after 1 week
Got my replacement phone today and hope that this time I have no further problems. I also had to return my previous one with a screen problem (see my post here http://forum.xda-developers.com/showthread.php?t=439410&page=2).
Everything went quite smootly and I liked the offer of a free of charge UPS pickup, so the only complaint I really have is that HTC send me a new phone but no replacement screen protector. Just the original screen sticker (the one with some writing on it) had been stuck on. It was in a bit of state like it had been taken off and put back on several times. I just called them to send me a replacement screen protector, but I don't hold my breath to get one. Probably end up buying it from the website.
I've bought an aftrrmarket battery and I have problems cahrging it.
It often shows itself as "fully charged", the led blinks from orange to green and it does not charge.
Whe in windows mobile, it shows 100% (not true) , but if i tap the battery icon i see the real percentage.
It does not recharge also when the phone is off.
BUT
I have noticed that when i am into android mode (one of the ported builds) the battery charges ...
SO
I think there is something preventing WM to charge the battery when it is 100%, and this control is missing in android.
now the question:
is it possible to "force" the charging in WM so that it bypasses the "100%" problem (like in android?).
Thank you in advance
I think an orange and green light means theres a problem and it cant charge,
I have an unofficial battery that does that too......
no, as i told you, there is something more.
when i am in wm or the phone is off, cahrging is almost impossible (orange and green led, wm icon showing 100% charge even if the battery is 1%).
BUT
if i switch to boot mode (vol down on startup, hspl screen) or if i am in android, THE BATTERY CHARGES.

So you are trusting android, in beta on these phones, over the default battery charging software?
I hope you don't blow up your battery.
Do you still have the original battery? Does it charge properly in WinMo?
I don't know if this is any help but... I also bought a very *ahem* low priced battery and experienced the same problem you mention. This was before android was stable so I have yet to try that, but I was able to fully charge the battery in winmo by putting the phone next to the air-conditioner. My thought when I read your post is perhaps that winmo is running the phone hotter and inhibiting battery charging. Somehow, I feel as though I'm grasping at straws...
'Force' and 'lithium-ion battery' should probably never be in the same sentence.
The flashing LED is an indication of overheating, thus the system stops charging until the temperature drops.
Try charging it someplace cooler.
If that doesn't work, the a method I read about is to run the phone until it totally flattens the battery, then put it on a full charge for at least 4 hours.

or, turn the phone off while charging will help keep it cooler as well.

Darn, I knew I forgot something
I have one original battery which the phone came with, and THREE oem chinese batteries which look exactly the same, except for the lower barcode which is tinier than the one on the original battery.
I only charge them outside of the phone, with an ac mains charger, and they go to full 100% since it's what the phone say when I switch them.
Whenever I charge them in the phone (only time it happens is when I'm in my car and use the lighter charger) it's just math, they end up in the green-orange led loop, and they stop charging.
It's well known and it's related to overheating, but at least they do not drop as well, which means I can go on and use them for gps navigation or any other task and the battery will stay at the percentage at which I left it.
I also have the same behaviour of OP, that is, taskbar icon says the battery is 100% and NOT charging, info panel after tapping taskbar reports real percentage, S2U2 reports real percentage in green, which means S2U2 sees it as charging. Anyway, as soon as I go home, I wait for the battery to drain to at least 10%, switch it out and slap it into the mains charger.
My oem batteries last up to 3 days.
I have the official HTC extended battery and with the latest chucky rom i have been using it wont charge in the phone anymore. It always used to with no problems. There is something missing software wise that prevents it from charging.

Is the middle pin of the battery contacts bent or different to the others?
The green/amber flashing means "charging problem" which can be due to overheating, but also can be due to an incompatible battery.
When I got my HD2 with the original O2 ROM, the HTC large capacity battery wasn't compatible, this required a ROM update.
If you're running stock, make sure you've got the latest ROM.

Nope it seems fine. It charges the standard battery ok.
As I said im running Chucky ROM. I had something like 21st July chucky ROM on and it charged. Update to the 11th August ROM and it wont charge. Tried the 5th August the same. Havent had chance to go back to the 21st July one to check.
Incidentally I dont have green amber flashing lights. I have alternate Green and Red flashing.
The battery charges perfectly well in my desk charger and runs the phone fine it just wont charge in the phone.
Have a TMOUS purchased in May. Latest stock rom/radio. When the battery is super low it goes through the process of shutting down - but when I plug it into the charger the phone will boot instead of staying shut down and charge. Will attempt to boot then go into Sense then shut down again and do the same process all over again. The only way to stop it is to quickly power down and it will stay down and charge. In any of the situations the phone appears to be charging.
Is this a problem with the ROM/Hardware or is something going on with the battery? Have an 8GB SD card with Android (no boot loader) and thats pretty much it.
Any advice would be appreciated.
I doubt that your battery is gone bad, but there are chances, try to condition your battery
Its just a little strange that the when the supposedly dead phone is plugged into a charger it boots up without pressing the power button. Don't think thats normal. Also when plugged into a charger when the battery is "dead" or near dead it should boot up and charge. This one doesn't - it boots - shows an LED charge light and then powers down and reboots. For some reason the battery with such a low charge can't power the phone and charge at the same time.
Will attempt to do a hard reset - maybe HD2 Tweak or something else did something to the registry and try it again. Since its under warranty will request another battery and take it from there. Don't think anything is wrong with the phone's hardware because it functions flawlessly.

If the battery drains and shuts off because it's out of juice, it WILL turn back on as soon as you plug it in, but it shouldn't keep rebooting after that...
Also if it's just shutting down on you in Android without warning when it's low, you need to condition your battery in Android so that it has the correct batterystats info.
No something is wrong. Ran it out of juice in WM this afternoon. Got the error message let it go. Went down and shut off. Plugged it into a car charger USB/cig adapter. Powered up go to tmobile screen/radio code then animation - rebooted did the same thing without touching it a few times then shut off - light led for charging did not appear.
Pulled battery - when charger disconnected - plugged charger - red light no reboot. Tried it again - same results with a hitch - it froze when it was charging - accessed internet explorer then it did a hard freeze - had to press reset button.
Don't know whats going on at this point - it shouldn't have done the freeze. So I'm going to experiement - pull the SD card (has Android on it) and try it again without the card. Try another card, try another charger and see - if I get the same results its either the phone or battery. When I have a charge greater than 5% there are never any problems. Only when battery level 0-1%.

Your battery pins aren't bent are they? (The little guys on the phone side that smash down when you insert the battery)
No, they are fine. I did call T-Mobile this afternoon and spoke to a level 2 tech - they think the battery is bad. Under warranty and have to call HTC tomorrow morning.
The phone does charge and does get to 100%. Drain in Windows seems fine and uniform but it does drop quickly once I get to about 20%.
Because of the reboot issue I think one of the cells is bad. Doesn't seem to want to trickle charge when the battery is that low. Tries to reboot - but can't get enough juice to sustain itself. Should just bypass through the battery as its charging. Either its the battery or somehow the charging circuitry is bad - who knows - with a new battery if it still does it then is the phone's hardware.
Will stop using Android for a while until this gets worked out - although I prefer the browser over WM 6.5.

Def sounds like a battery issue then, if the pins aren't bent because that is the biggest symptom of bent pins.
This morning my HD2(7) was totaly empty. The power button did not do anything and the phone won't start up. When I hooked it up to the charger, the red led did not come up and the phone was not charged at all.
I tried to do a soft reset, but nothing happend. Some posts on this forum suggested a hard reset, but I did not want to loose all content on my phone.
It seems that the real solution is very simple. Just connect the phone to a charger, remove the battery completly and then place the battery back in the phone. The HTC will now start up and begin to charge.
So, just a waring, do not hard reset when you phone stops charging...
Cheers, Rene
Funnily enough I put my phone on charge last night, forgetting that I'd also switched it off... Came to it this morning and remembered about the charging issue when switched off. Tried to switch the phone on and nothing... So I went to change the battery with the wife's HD2, but managed to mix up the batteries and found that my phone would switch on afterall and it was also fully charged. The wife had her's on charge overnight as well, so both batteries were showing as being full...
Charging issue has been fix up in the MAGLDR 1.13 version

There is no doubt that this is sensible advice, but there may be an overlap with another issue here.
I have noticed - and it could just be specific to my phone - that if the phone gets to the point where it shuts itself down to conserve power, it will often not restart from the power on button and only pulling the battery will wake it up. This seems to be a 'feature' of WP7 on HD2.
Interestingly, on several occasions where the battery has been fully charged (and still plugged in) the phone will not start from power on if I do a shut down - I tried it less than an hour ago after making a couple registry tweaks and only pulling the battery would persuade a fully charged phone to restart. It would be interesting to know if others are finding the same.
Where the battery is seriously discharged, it can take several cycles of pull battery - boot phone - phone decides it has insufficient battery and shuts down - pull battery - boot phone...before WP7 decides it has had enough juice trickled back into it to be able to charge - sounds crazy, but there you go.
MAGLDR v1.12 doesn't support charging, which doesn't help. I'm going to try v1.13 to see if agarp is correct - here's hoping.
Update: I don't think MAGLDR113 supports charging directly but I believe it has something built in to prevent a plugged in phone running down the battery. Not sure about exactly what, but it suggests something about booting the phone if plugged in and battery is at critical levels.
i just got the phone nad first charge i charged it whe ni got it and now its dead im charging it battery is very weak compared to nexus one i had.... but is it true that if u discharge it completley and then charge it completey and repeat 3-4 times battery gets good? i also heard over a little time that battery gets way better? any one can relate to this?
Sounds like you could benefit from re-calibrating your battery. It can be done manually through recovery by resetting battery stats, or easily through an app like this one (you must be rooted).
how u do it without rooted and i heard discharging 3 times and fully charging works? any update on that
There's lots of different "methods" floating around about how to calibrate your battery, many of which actually don't make much sense. The ones that do make sense to me involve deleting the batterystats.bin file. That app TeeJay3800 linked to pretty much does just that. For rooted devices, all the ClockworkMod recoveries have an option to delete battery stats in the Advanced menu.
I think this file is located somewhere in /data but I don't know off the top of my head. I also don't know if root is required to delete this file. Maybe try finding it with Terminal Emulator and attempt to delete it. If that doesnt work, then you'll probably have to root the device (or maybe just temproot it).
yea i did it yesturday nad today its still bad about to attept 3rd charge and im waiting till it dies it went from 39% to 19% within an hour wtf is this??? im waitign till ti dies then recharge to fully
i also did this wthich is good but will it mess anything up if the phone is brand new and is charging fine
Connect the phone to the charger with the phone powered on, and allow the phone to charge until the notification LED is green, indicating the device is fully charged.
Disconnect the phone from the charger, and power it off.
Reconnect the phone to the charger with the phone powered off, and allow the phone to charge until the notification LED is green.
Disconnect the phone from the charger and power it on.
Once the phone is powered completely on, power it off again and reconnect it to the charger until the notification LED is green.
Disconnect the phone, power it on, and use it. You need to use this sequence only once.

This is "bump charging" and all it does is try to fill up your battery as much as possible. It's like topping off at the gas station. It won't do much as far as battery calibration. You may see a minor improvement in battery life after a bump charge, but you'll have to do it each time you charge.
Keep in mind that battery life is dependent on many factors, including your usage pattern. Improving battery life is a matter of being mindful and selective about what connections you leave open (bluetooth, GPS, WiFi, account sync) and what apps you let run. Screen usage plays a role as well. Network signal strength also plays a part, but that's not something you can control. Don't use taskillers, they cause more problems than they solve.
I'm assuming you're still on the stock ROM. If that's the case, you should be aware that there's lots of extra stuff on there that runs in the background to support the HTC Sense overlay. The biggest improvement in battery for me was (a) flashing a custom ROM without all that junk on it and (b) flashing a custom kernel which both underclocks the CPU and uses lower voltage settings.
If after all these considerations you still think your battery is borked, head over to a T-Mobile store. They may give just you a new one, otherwise it'll probably cost you not very much.
