Found this on Desire Android Development forum ... http://forum.xda-developers.com/showthread.php?t=755903 ... MOD Edit: Link created.
Found this on another forum, I have done this a few times myself (do it whenever i flash a new rom because i always clear battery stats, can't hurt). Have found that it does top it up a fair bit. Before doing this i find my desire will drop to +-93% straight off the charger, however this keeps it 100% longer and i actually get to see the numbers 99-94%
Worth a go in my opinion because it only takes 5 mins of your time and can't hurt the phone... So any minor gain from this process is a win...
Hi *******, I understand your concern regarding battery life on your Nexus One device. The following steps should significantly extend the battery life on your phone. Please 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. If the issue of battery life on our phone persists, I recommend you contact our HTC accessory department directly.

From what I have read on there forums the whole procedure should go like this :
So combining the two bits of info we've compiled, the best way to calibrate your battery is as follows
1: Charge phone whilst on till LED is green.
2: Disconnect phone from charger, power it off.
3: Reconnect to charger with phone powered off and allow to charge till LED is green.
4: Disconnect the phone from charger, power it on. Once completely powered on, turn it off again and reconnect to charger until LED is green.
5: Reboot into recovery (back button held at same time as power button) and wipe battery stats.
Battery should now be calibrated.

So I am trying this right now as I type this but the problem I am running into is I charged my phone to full - green led . Problem comes when I power off phone and plug charger back in the phone automaticly boots into Clockwork Recovery ( Thats with the stock charger plugged into a wall socket not computer ) I tried to charge phone that way but led never turns green so I charged it all night that way. Powered phone back on fully , then turned off and charged again in clockwork recovery led never turning green . Cleared batt data in clockwork recovery and powered on . Battery life is unimproved drains fast if not faster than before lol . Hope someone can help . Main problem being how do I get phone to charge with power off and not booting into clockwork recovery when charger plugged in.
Now I have read else where
It seems the old battery icon was part of the original recovery, so there is no fix is on the horizon. Really, no functionality has been lost. The phone is never really off when charging anyway. Better to just leave the phone on and let the screen go off while charging.

HTC Aria - Unrevoked3 Root Method - Attn1's ROM: Liberated_Aria_b005
Hope I made sense I am noob to all this
Ok so here is what I am doing right now - My Calibration Breakdown
1: Did cjperone's !!!!Battery Saver Fix? hit fix permissions in ROM Manager app ( Don't know if this is needed but said what the hell go for the gusto )
2: Rebooted phone per ROM manager app telling me to
3: Charge phone while on till LED is green. Battery was at 4137v ( From what I have read 4137v is opptimal full charge )
4: Disconnect phone from charger, power it off.
5: Reconnect to charger with phone in Clockwork Recovery and allowed to charge for 4 hours . (Since Led Will Not Turn Green )
6: Disconnect the phone from charger, power it on. Once completely powered on, turn it off again and reconnect to charger with phone in Clockwork Recovery and allowed to charge for 4 hours . (Since Led Will Not Turn Green )
7: Since I was already in Clockwork Recovery I wiped battery stats and rebooted phone.
I will use my phone normally today and will see what happens. I will post back results later on tonight.
Well first try not so good with method above I rebooted my phone and within 30 minutes of normal use charge was already at 86% honestly I think froyo 2.2 has a lott too do with the results people are getting. So I installed the newest version for the aria on the forums and gonna try again. I'll keep you updated.

if u did a nandroid from the beginning before u rooted ur phone u can do the original method then flash ur most recent nandroidd back up
Hi mate, glad to run across your post I was wondering what was up too. I have the same setup, but so far mine charges in a normal off status but still doesn't hit green. If I turn it on it is at 100% but not for long. It's definitely draining quicker than the 2.1 setup I had before. Not sure what to do exactly.
First, I'd like to thank all devs who spent a lot of time on developing NAND Android for HD Mini!
(I don't know whether it's alright to put my question here)
I've been using sp3dev's release (v2) but I have doubts with the battery bugs...
I get something like this:
When the phone is off, I try to charge the phone with A/C power, the LED light will turn to red. (It's normal until here.)
But when I plug-off the power, the LED light still keep lighting and does not go out! When I try to turn on the phone (by pressing the power button), it has no response. What I can do is to pull the battery out and put it back to turn on the phone...
I asked this in other forums, but some people say they don't have this problem. So anyone know if this is my phone's problem or the ROM's bug?
Any solutions to this?
Thanks.
I have this problem too
I using CM 7.2 - 2.6.35
if you want to charging battery when phone is off goto recovery and select power off and connect dc charger
have the same bug too :S
the only solution for me is to take out the battery and put it back
Hello, same symptoms, although I think the battery is charging! Led indicator and key backlight not working properly, using [schlund] photonic CM 7.2 - 2.6.35.
For me the solution is to wait for 2-3 minutes with a cable in the phone (battery is charging) remove and set back the battery and turn on the phone.
I have this problem too, from first time to flash ROM as android.
I using CM 7.2 - 2.6.35
I think it is cause by boot and recovery.
same issue with my phone....
Hi,i have the same problem.maybe schlund or others could help us..

Hi.
Sometimes when I unplug power charger or disconnect USB cable from phone, battery icon still showing charging status, even Battery Status app showing charging state. Only powering off/on device restore correct state of battery icon. Next time when this state occur I will try to record small video and post it here.
Does anyone has the same problem as I have?
Cheers.
I had this happen on my Samsung Focus once. I turned off and back on to fix.

-I was using the original wm, but now i've flashed android with sense 3.5.
-No
-No, i used the usb cable and nokia charging kit.
-Not so much it can't take a day.
Also i can hear a strange noise coming from the charging kit. when it's plugged in. Could be an hardware error or software?
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.
can't flash back to wm.

another problem
Ok, i've flashed the original wm 6.5 greek rom.
After that, my phone won't charge at all.It shows a solid orange light for 3 seconds then it starts blinking.
I can start my phone but it closed soon, after wm boot.
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.
Done
all night

Thanks for the help
hello
Still me, new info
I tried with another battery.Surprize my phone shows that, that one is empty too.
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.

Any known reason why I Can't power-off my phone while charging battery??
It happens to me in every Samsung custom ROM I use...
Of course I do wipe everything (data, system. Internal SD, kernel and so on
what to do??
Thanks guys
Strange bug.. i've had it where i couldnt turn ON the phone if the charging cable is already plugged in, also on my samsung s2
What do you mean by not being able to turn off? If you mean that it show a battery with the percentage that is normal, it's called offline charging.
Try to keep pressed the power button until the screen goes black to force a shutdown.
What I mean is that when I turn off the phone while charging what actually happens is that the phone will reboot and not stays off
