I'm ready to replace my iPhone 5S battery because keeps draining all the time in standby mode and even doing all the troubleshooting and tips provided by Apple and by any good-know forum, the battery is at 95% with more than 560 cycles and I'm tired of charging it 2-3 times a day with a minimum of 2 hours of usage! The real questions stand here : In my country there are not authorised reseller, no Apple Store at all. So i just wanted to know if someone could provide any tip (serial number, model, etc) of an original battery for iPhone 5S, because where I'm going to replace it, the seller showed to me the battery that was original, but I was unable to take a photo to the back of the battery and I want to be sure that this replacement is going the right way! Any suggestions please?
