Hi there, I replaced my battery and used icopy to keep sn. when I plug in 3utools 3utools show 100% ok. But in setting iphone x keep the message maintenance and if i click show 77% same percent old baterry
Changing the serial number to the original one will have no effect. You also need to transfer the flex assembly from the original battery as that is where the chip is that is linked to the phone. You need special equipment for this procedure like a micro spot welder and micro soldering iron.
But its just happens with X?
coz another one like 8 plus / xs / 7 I use icopy and works well.
