LG eXpo GW820
LG EXPO GW820 battery problem.
I had the same problem with mine. I thought it was a defect at first. But when searched the FAQ about LG EXPO GW820, i found a way to solve this.
1. Start – Settings – System – Power – Advanced – Select ‘On Battery Power’
2. Start – Settings – System – Backlight – Select ‘On Battery Power’
then, change the backlight duration to the way you want 🙂
