Typical causes
Why a phone loses runtime or shuts down.
- Normal cell aging and repeated heat exposure reduce usable battery capacity.
- Background software activity, weak signal, or high screen use can increase drain without a failed battery.
- A worn cable, damaged port, or board-level power fault can prevent a healthy battery from charging correctly.
Repair versus replacement
Replace the battery or the phone?
A battery can be a practical repair when it is the main limitation; broader age, damage, and performance needs still matter.
Repair may fit when
- Battery condition is the primary fault and the phone otherwise works well.
- The device still meets your performance, camera, storage, and software needs.
Replacement may fit when
- Battery symptoms come with serious board, screen, frame, or charging-system damage.
- The phone no longer meets your daily needs even with normal battery life restored.

No. Apps, software, charging equipment, ports, heat, and hardware faults can also contribute.
Is a swollen battery dangerous?
It can be a safety risk. Stop charging and avoid squeezing or puncturing the phone; bring it for evaluation.
Can you test the battery first?
We inspect the symptoms and device condition before confirming replacement.
How long does replacement take?
