If the battery health of i4 and your iPhone are inconsistent , what should you do ?
There are 3 steps for your reference :
1) First : connect your iPhone to i4 , choose the flashing function
2) Second : this step is very important. When the flashing progress reaches 30%, disconnect the iPhone and i4 directly.
3) Third : reconnect your iPhone to i4, choose the flashing function again, until the flashing is complete 100%
4) Fourth : recheck your iPhone battery health and the i4 battery health , then you’ll notice they are same .
