Hving issues with my iphone 5s, Battery life is sitting around 40-60% and phone randomly just shuts off and the only way i can restart it is having it plugged in and using the Hard restart buttons to restart my phone. This has happened about 6 times in the last 6 weeks or so, Any ideas what might be causing this issue? When i turn my phone back on, my battery life is usually only a few notches below where it was when it shut down. and thats usually after about 25-30 minutes of letting my phone sit on the charger, for example tonight it did it, phone was at 56%, when i turned the phone back on, this time only around 10 minutes after, my battery was down to 33%
Is it that i need a new sim card?
or is it something with the battery itself?
