Hey guys just like to confirm, so it is better to charge your iPhone when ur not using for example when u reach home from work and battery left50% just charge it don't have to wait for 20% or lower this way is better?

Bro 2 days but how much usage time you got out of it. I bought the iPhone 3GS 8gb the bat life is horrible to me, only can get about 3 hours usage time. Mostly use iPhone to surf net on wifi and play game called High Noon that's all.
