    Hi, last night and this morning I've noticed an extremely worrying problem with my iPhone 4S.

    I unplugged my phone from the charger this morning at around 10am and when I checked back at around 3 (without one bit of usage) the battery had gone down to 54%. Now I left it again from 3 untill just now at around 5.10pm and the battery has fallen now to 20%!!!

    I haven't used my phone all day, I've ended all running apps but the battery is dying so quickly and the phone feels warm. What could the problem be? Should I take it into the Apple store or is there something I can do myself to fix it?

    PS. I noticed that this happened last night, but has never happened before then.

    Why the attitude?

    I've already tried rebooting it.

    I don't want to mess on with the insides of the phone when I don't know what I'm doing... recipe for disaster.

    Should I just take it into the shop? I only bought it from the Apple shop in May!

    Is your phone jailbroken?

    I seem to get this issue once a month or so. The big indicator for me is my phone will be warm. I honestly have not been able to pin point the cause of the problem. Mine is jailbroken so I always thought it had something to do with that.

    The only way ive been able to fix it is a combination of airplane mode for 5-10 minutes at a time and hard reboots (with home+power button) followed by airplane.
