7 Signs Your iPhone Battery Needs Attention
Learn the common signs of iPhone battery wear, from rapid drain and shutdowns to heat and swelling.
Battery performance changes gradually, so early signs are easy to miss. Paying attention to charging speed, heat and unexpected shutdowns can help you act before the phone becomes unreliable.
What the symptoms can mean
Rapid battery drain, sudden percentage drops, shutdowns under load and unusually slow charging can indicate an ageing battery. Screen lifting or a swollen case needs prompt attention.
What to do next
Check Battery Health in iPhone settings and update iOS before assuming the battery is faulty. If the phone is swollen, hot or physically separating, stop charging it and arrange an inspection.
When to arrange a diagnosis
If the problem continues after safe basic checks, a proper diagnosis is the best next step. It helps separate a replaceable part from a deeper board, power or software issue before any repair is approved.
