Mine had "false charge" battery icon problem and I tried different methods until I found it by accident.
The phone battery totally drained out even I was sure the phone plugged, and the charging icon (when the phone is off) kept flashing, so I change different cable, and lo and behold, the phone charge again. Then I use the same cable and I found the battery drains on other phone as well.
The "false charging" may be caused by insufficient input voltage and the phone has to lower the voltage to charge and triggers the problem.
Here is the fix:
With the phone is off, use the cable to charge the phone and observe. If the phone does not flash when charging, the cable is OK, but if the phone flashes the battery icon when charging, use different cable.
Reboot the phone to Clockworkmod recovery, and wipe the following:
battery status
dalvik cache
cache
Reboot the phone normally and let the phone charge normally
The "false charging" icon should be gone.

Hi there !
I hope someone could help with a weird problem.
history:
I've got a T-Mobile MDA compact 3 and I had an issue with my battery. It was completely discharged (~3% left, flashing red) and I was driving / navigating in the car until I noticed that the car-charger was not connected. So I plugged it in - and it was hot in the car... and the battery was GONE.
(I know that a LiOn battery does not like 'hot' ambient temperature, I know...)
At home, I tried to charge it with the power adapter : no luck.
OK, I thought, battery defect... so I bought a new one, Samsung labeld brand, not a 'China' clone.
Now, with the new one I've got the following problem :
- the battery will charge with either USB / car- or power plug charger, BUT it will go from consant organge (ok) to flashing orange (not ok, normally that's "notification" / message arrival) instead of green.
- using the power plug charger, after a night, battery is "empty" again, so charing (constant "orange" LED) -> flashing orange LED -> flashing RED in the morning -> empty
- the "BatteryStatus" tool and the system control panel will show "charging" while charging, but the percentage will never increase (e.g. if I start charging at 30%, it'll stuck on 30%...just displaying "charging"). If I now charge for - let's say 1h, it's still on 30% (despite, that I know it will last for 2 days)
So the problem is, that the PDA doesn't know the actual charging level. But that's also not true: cause if I do a Soft-reset, it's back at 100% (or less if I have not charged fully - which I don't know as it doesn't go to "green LED" anymore.
So again, in short, I always have to reboot to see the current charging level, and I'm missing the "green LED" full charge level (instead "orange flashing LED" notification.
I guess that the levels (low, high, current) are somewhere stored in the registry, or ? I did a hard-reset, reinstalled all applications, but same...
Any hints ? I hope a firmware upgrade would reset the battery status, but as there is no offical firmware for the T-Mobile MDA 3c, I'm stuck... or ?
I have the exact problem on my P3300... When i try to charge with my usb cable everything it's ok...
But when i am trying to charge with my car cable it will go from constant organge to flashing orange... Also the temperature is rising very fast... It has reached to 80 degrees C°
It stop charging when temperature is over 50...
Anyone there to help us???
I get a similar problem.
Allthough, charging on adapter "seems" normal.
Led turns green and battery status via system settings are at 100%.
When disconnecting from the charger, the battery level drops to the exact same level as before charging (example -> battery at 48% -> connect to charger -> after an amount of time LED turns green, battery status is at 100% on the PDA -> remove cable -> battery back at 48%).
Charging in the car or on the computer does not give this problem.
Tested my battery and charger on another unit -> no problem.
Tested another charger and battery on my unit -> same problem.
Device is going back (THIRD TIME in 2.5 months) for repair.
No more Artemis / HTC P3300 for me ......
after some quick seach i found there a several methods to calibrate the battery with/without wiping battery stats
Method 1

· Wipe your battery stats...
1. Allow the phone to discharge completely
2. Boot into recovery (hold Home and press On) plug the phone in if you don't have enough charge to get into recovery
3. Select Wipe > Wipe battery stats
4. Go back and Reboot
5. Leave the phone to do a complete charge (preferably over night)
Method 2
1. You will need to charge the phone to 100% (while the phone is off).
2. Leave charging cable plugged in.
3. Boot into recovery and wipe the battery stats (should be under Advanced).
4. Then boot into Android.
5. Then remove the charging cable.
Method 3
Calibrate your Battery
Calibrate the battery by completely draining it until the phone completely shuts itself off.
Turn the phone on again and let it shut itself off one more time.
Then charge your phone while it is off for over 8 hours.
This will fully charge the battery so that when the Android is turned on, it now sees the battery as full.
It is recommended to repeat this process at least one more time.
You should see a significant increase in your battery’s charge life.
Calibration of a battery can be done at any point and a maintenance calibration is recommended every month.
RECALIBRATION:
A recalibration is mostly needed, when dealing with different kernels (ROOT!). Most custom recovery images provide the option "battery stats wipe" under the menue "Wipe".
Here is how ya do it!
1. Enter Recovery Mode
2. do a full nandroid (or nandroid+ext) backup
3. Enter "Wipe"-Menue
4. do "Battery stats wipe"
5. reboot
Then you just take the steps from a bove to continue:
Method 4 (without wipe stat)
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.
Tried this and there doesnt seem to have an significant effect.
and now i'm trying method 3 with wiping done first.am i doing it wrong?
None, I charge every night so not bothered so long as battery lasts the day
i tend to have the problem of removing the charger and the batt stats shows fully charge to 96 within 5 min..weird
actually i'm doing the 4th method right now
Apologies for another not charging thread, i have tried searching for a similar issue but no luck.
I put my DHD to charge as usual last night at around 40%, the charge LED lit up and the battery icon was showing that i am charging.
When i woke this morning, the charge LED and battery icon were still showing that i should be charging yet the phone now only has 33% battery, so clearly hadnt charged. I checked current widget and when the LED and icon show charging i only seem to be getting anywhere between a reading of 40mA and 270mA. With an occasional 300-400mA reading.
I seem to be able to intermittently get the phone to charge and the batt icon to rise by a percent or two but then it seems to stop again. As i am in work at the moment i am having to charge via USB from my PC. Therefore i am currently unable to try another micro USB charger and see if it is indeed the charger or the phone.
Has anyone else had a similar issue, says it charging but it not??
Or anyone have any ideas of a solution??
If it matters i am currently using LeeDrOiD HD V3.3.1 GB. Id rather not have to return it to HTC as i am unsure of how to return the phone to default easily so it could be repaired on warranty.
Thanks in advance,
James
Firstly, download CurrentWidget, set refresh to 15 seconds, and make sure you set it to display battery voltage. If it is showing around 4200mV, it is charged, and you have a problem with the battery gauge.
To double check, turn off your phone, and see if the light goes green at 100%.
Boot back up, just to see if a reset fixes it.
If not, reboot into recovery, and wipe battery stats (or do it properly, turn off, wait until light is green, wait another hour, then boot into recovery and wipe battery stats).
Turn back on, and see if the problem is sorted.

Phone won't chrage or get connected if I don't reboot it with the cable on and after it does when I unplug it the usb and 100% charged notification always shows. Also when I reboot normally it shows the battery charging part. Flashed the device with stock rom twice which didn't work. Battery percentage goes up. Like I have 20% at first then it goes to 96%. Also kies don't recognize it.
Help!
I believe I tried all available CMW for MT7-L09 (MATE7_CWM.img; cwm_mod_mate7.img; recovery_touch_mod_test.img; TWRP_2.8.0.3.img) but only one allows to charge my device WHEN OFF: MT7_CWM_CN_EN.img the one provided by Fooox1 HERE.
When I connect device to charger, the device simply remains off (no battery charging icon, no led), TWRP reboots to recovery; only MT7_CWM_CN_EN.img works fine...
How is it possible? Can anybody charge his device WHEN OFF with some CMW???
Please, let me know...
Ciao Leonardo. When I installed CWM on the occasion on B127 I remember that the icon of the battery during charging with phone off was different. No circle running. Just battery simble filling-in animation. But it was charging anyway. When I re-flashed the stock recovery, circle running icon was back. Still charging properly. But for me, in both cases was charging properly. I always charge M7 when is off.
