I have Sony Arc phone which was spoiled by me (story OutTopic) as it won't charge lion battery anymore. the phone itself works perfectly. I don't want to do the regular 3AA to USB charger way. Trying to use 3 NiMH in the battery pins of the phone. Getting in ranges 3.7V+ from my 3 rechargables. Original sony li-polymer battery says 1500mA - 5.6Wh.
The phone starts with the logo. Does Experia animation and reboot and starts again in loops.
I suspect my battery is not giving enough current or voltage for android OS to start loading. I was wondering if I can put the phone on 4AA NiMH meaning ~5V, will it burn the phone forever (just thinking).
Could not find notes on internet about trying this. everyone does USB route. Please suggest what options can help my case?
