Common Mistakes When Replacing Phone Batteries

Many repair technicians make repeated missteps during battery swaps, which easily cause battery swelling, cable damage or hidden safety hazards. We

sort out four high-frequency mistakes and standard operation guidance for your daily repair work.

1.Prying the battery forcibly: Using sharp tools to pry stuck batteries may puncture the lithium cell and trigger overheating or fire risks.

2.Violent pulling of flex cables: Rough tugging on battery connectors will break internal lines and lead to power failures.

3.Leaving adhesive residue: Old glue leftovers cause uneven pressure, resulting in screen lifting or abnormal fitting after reassembly.

4.Excessive battery bending: Severe bending damages the internal protection circuit and shortens battery lifespan greatly.

Safe Operation Guide

• Use dedicated battery pull tabs to slowly take out the old battery;

• disconnect connectors gently by hand instead of yanking;

• fully clean residual adhesive before installing a new battery;

• keep the battery flat without folding or squeezing.
