iPhone 4s shuts off randomly and goes to low battery screen
Got an iPhone 4s from my cousin recently and the back is cracked pretty badly. Ever since I've had it its been shutting off randomly shows the spinning circle and then goes to the dead battery screen. Once I put it in the charger it turns on after the amount of time its been off and it will be at a different percentage. Battery also drains extremely fast and changes to random percentages. I'd love to know what's causing it and how to fix it.
