Battery Problems We Fix
Every symptom listed below is something we see and fix every day. If you are not sure whether your issue is the battery or something else, we diagnose first, at no cost.
Battery Draining Fast
Your iPhone used to last all day but now runs out in a few hours. This is the most common sign that the lithium-ion cells have degraded and the battery needs replacement.
iPhone Shuts Off at 20%+
A degraded battery cannot deliver the peak current the processor demands under load. The phone shuts off suddenly even when the percentage shows 20, 30, or 40%.
Battery Health Below 80%
Apple recommends replacing the battery when health drops below 80%. At this level, iOS may enable performance throttling, slowing your iPhone significantly.
iPhone Runs Hot
A battery that runs unusually warm during normal use or charging is losing efficiency. Excessive heat accelerates cell degradation further.
Swollen Battery
If your screen is lifting away from the body or the back is bulging, the battery has swollen from gas build-up. This is a safety issue, bring it in immediately.
Performance Throttling
iOS throttles CPU speed when the battery cannot sustain peak current. If your iPhone feels slow and Settings shows a performance management message, battery replacement restores full speed.
Stuck at 1% for Hours
The battery percentage freezes at a low number and will not move even while charging. This indicates a failed battery cell or a faulty battery management chip reading.
Charging Percentage Jumps
The battery jumps from 40% to 10% instantly, or from 90% to full without passing through intermediate steps. This is a calibration failure caused by cell degradation.
