does not come on.
my phone does not come on even when on charging.....the apple sign will come ON and off several times...but will never come on....
苹果 iPhone 5s 于2013年9月10日公布。该设备的维修与以前的型号相似，需要螺丝刀和撬棒。可使用GSM或CDMA / 16、32或64 GB。颜色有银色、金色和太空灰。
The phone switches off immediately when unplugging the cable while the apple logo is displayed correct?
Right now it is boot looping while plugged in.
If all these conditions are met then the battery is almost certainly faulty and needs to be replaced.
Otherwise the fault is most likely not the battery and is something else which means I may have to ask more questions to you to find out the most probable causes.
