Iphone 4

[kh70]

In the last couple of days my iphone 4 battery has been running out really fast. I have check to make sure all things are turned off like 3g, bluetooth, notifications etc I only have 100 pictures on, 3 apps which are not running and safari history been cleared.

Can anybody give me any tips? Can the battery be replaced?

Don't know the reason yet, but my 4S went from 78% when I set the Alarm last night down to 3% when Alarm went off this morning, nothing active that I can see?

let it run out then press off and enter buttons together to re-set phone & recharge.

i think you have to replace your battery ,its recycleing charging period is decreased due to overcharging of li-ion
