Why Is My Phone Overheating? Causes and What to Do
A warm phone is normal sometimes. A phone that gets hot often can be a sign of a battery or charging problem. Here is how to tell.

Heat is one of the main causes of early battery wear. In Merced summers, avoid leaving your phone in a parked car or in direct sun, and do not charge it while it is hot. If your battery drains fast, swells, or the phone shuts off, a battery replacement usually fixes it the same day.
Summer afternoons in Merced and the rest of the Central Valley often go well above 100°F, and a parked car gets much hotter than that. Lithium-ion batteries do not like heat. Every hot day wears them down a little faster.
What heat does to your phone
- Faster battery wear: the battery holds less charge over time and drains faster.
- Swelling: a badly worn battery can swell and push the screen or back glass out.
- Shutdowns: your phone may show a temperature warning or turn off to protect itself.
- Slow charging: phones slow down charging when they are hot.
How to protect your phone in the summer
- Never leave your phone on the dashboard or in a parked car.
- Keep it out of direct sun at the park, pool, or on the job site.
- Take thick cases off while charging on hot days.
- Let a hot phone cool down in the shade before charging. Do not put it in the fridge or freezer.
- Avoid gaming or GPS navigation while the phone is charging in a hot car.
When to replace the battery
If your phone dies before the end of the day, shuts off above 20%, or the screen looks lifted, the battery is likely worn or swollen. A swollen battery should be replaced right away. Stop charging it and bring it in.
