Common iPhone Battery Issues
Even the most advanced iPhones can run into battery trouble—here’s what to watch for.
Battery Health Warning
iPhones include a helpful feature under Settings → Battery → Battery Health & Charging. If it shows a message like “Service Recommended” or battery capacity below 80%, performance could suffer, and a new battery may be needed.
Slow Performance
When your battery health declines, your iPhone might throttle performance to prevent unexpected shutdowns. Apps load slower, multitasking gets sluggish, and your phone just doesn’t feel as fast as it used to.
Sudden Shutdowns
If your iPhone powers down with 10–30% battery remaining, this is a major indicator that the battery can’t hold a charge properly. Cold temperatures and high-performance tasks can make it worse.
Swollen Battery
A bloated battery is one of the most serious issues. It can cause your screen to lift or your iPhone to feel misshapen or warped. If left unaddressed, it could damage internal components or even pose a safety risk. Visit us immediately if you suspect swelling.
