battery problems

[Bacon_Puffs]

i think it is a phone problem as i checked out both chargers,the only difference was the chinese one that came with phone was 1.0a output and the samsung one was 0.7a output

The output from the adapter isn't so important in regards to being too much. The battery/phone will draw/push what it's capable of.

My thought is that it might actually be faulty/inferior battery design as opposed to the phone.
