(Samsung Galaxy 2 - rooted)
Greeting folks,
I have the issue of receiving the "voltage too high - disconnect from charger" after it is removed from charger - just like many of the other posters.
In my case, I know what caused the issue but do not know the correct or most methodical way to perform a fix. A miki of vodka on my coffee table had fallen over and spilled unbeknownst to myself, and when discovered my bottom of phone was wet lying in the thin "puddle" - after perhaps 20-30 minutes. It was the wetness / Mr voddy that caused the phone to malfunction.
I left the phone, face up and with battery removed and cover off over night (as one is directed to do with a laptop (but which would also include removing the hard drive and all other removable devices) and when I restarted the phone 10 hours later, it exhibited the "voltage too high" with a flashing battery icon and notifying beeps.
The phone appears to work fine well plugged into the charger.
So, knowing that it was definitely a "moisture incident" that led to this, I am thinking that I need to either clean something OR maybe do something with the battery as suggested by our friend who discharged his battery to 17% twice and then (and I need help on this part) "reset" or "reprogrammed" the battery?
Many thanks for any help
