Hello, I have an iPhone X which had a battery replacement, and was working fine until it randomly restarted and the battery percentage now shows as 0%. The battery health also shows as service, but before the restart it showed as 100%. It also randomly restarts, does anyone know what the issue may be? Thank you
Your battery have loose connection with battery connector or battery connector have been damaged while replacing battery…..so go and have ok on it
If you have ruled out the battery it will most likely be an IC2 SDA or SCL problem. Check readings on battery connector data pins. Check for nudged components Q3200 and Q3201. If all looks good replace U3300.
Sounds like you got a bad battery. Try another.
