Hi,as i meantioned above...what i want to ask is:

Everytime after i fully-charged my iphone,then i will play some games and sometimes when i finish played the game,the battery already dropped to 20%-30%..after awhile i need to charge again,so i was worry will it bring any battery problem since i always charge it after fully charge..

And if we keep playing games on iphone no problem one right?i mean will it bring any problem to touchscreen?since i always keep pressing the screen when playing game..or battery?

Sorry to ask this such question...just worry bout it..hehe
