    Hi there

    i have an iPhone 4S running iOS 7.1.2 which gotta the problem of shutting off with the battery almost full.

    I dont know if its a hardware issue, but I'm hoping that is a software issue so I'm trying to do everything I can to isolate and software issue.

    I did a reset on iOS but it didn't solve. The next step should involve a DFU reset using iTunes but it will update my iPhone to iOS 9 and as far as i know it will turn my iPhone unusable.

    The other possibility is revert it back to iOS 6.1.3 but it goes wrong, I will must make a restore to iOS 9 which will be a problem anyway.



    So, is there anything I can do without performming update to iOS 9 ?

    If a restore doesn't work the battery may need to be replaced which can be done at an Apple Store. They may make you install iOS 9. If you're jailbroken it could also be a problem with that.

    That's a pretty common symptom of a battery that needs to be replaced.

    Unless you have recently changed your battery, there is little doubt that the time has come. The Apple store is the best place to go.

    This iPhone has bought 2.5 years ago, with one recharge a day. So, it completed about 900 charge cycles. As far as I know Apple promises a thousand cycles holding 80% so capacity.
    It's to soon for a repleacement isn't it ?

    The reset I did was from iPhone itself, I did a "RESET CONTENT AND SETTINGS". Does it count as a complete reset like we do using iTunes in DFU Mode?

    I prefer to let the battery change my last option. Here in Brazil, Apple charge a lot for a battery replacement and I'm afraid it will not worth.

    Have it your way but your phone is showing classic signs of a battery going bad.

    1000 cycles is what Apple quotes for Macs and iPads. They only claim 500 cycles for an iPhone.

    Your battery is shot and needs to be replaced.

    No, but but it doesn't matter because software most likely isn't the problem.

    That's unfortunate.

    If you are worried about needing to update iOS (which can very easily turn into a one way street when it comes to reseting all settings) then I would at least try replacing the battery. I did it twice with my 4S with kits provided by ifixit, took all of about 10 minutes and cost like 30 bucks for the battery AND the tools to do it.

    Just an update:
    I've got an app called battery life that shows how many cycles the battery has. I did 610 cycles and my battery capacity is 76% of a new one. Is it a reason for my phone shuts down sometimes with 30-40 % of charge?

    It shuts down with 30-40% of the charge remaining because the battery is failing. I don't know if it is because of the number of cycles or because of a bad cell, or both. Honestly, it doesn't really matter. The solution is to replace the battery.
