iPhone 8/8+ Slow Charging/No Charging After DIY Screen Repair
Symptoms: After a screen or battery repair, the phone boot loops a few times during boot up, then never charges. The battery percentage stays at 1% or charges very, very slowly.
The Damage: There are some small components near the display/lcd connector that gets dislodged when the connector is disconnected from the logic board. More specifically, a zener diode (DZ3200) and a transistor (Q3200).
The Fix: Usually, some pads are also missing, so we’ll need to run some micro-jumpers to the missing pads and replace the missing components.
