K750i Can Not Charge The Phone Correctly - GSM-Forum

hooi76 · 07-02-2007, 03:00

I have a WATER DAMAGED K750i phone, I already wash the phone and flash with R1CA021, now the problem is the phone having a CHARGING PROBLEM. Last night, i check the battery at the side volume button and it shows 50%, then i put it to charge and at the end it shows fully charged. but the next morning i wake up, i check the battery level again, it show 50%. How to repair this phone? TQ
