What you need
Steps
Open Settings, tap Battery and scroll down to the list of apps by usage. Look at the last 24 hours and note the two or three apps at the top.
Tap each heavy app and check whether background activity is high. Go to Settings, General, Background App Refresh and switch off the ones you do not need running all day.
Open the App Store, tap your profile picture at the top and tap Update All. Old apps are a common cause of drain after a system update.
Restart the phone. Press and hold the side button with either volume button, slide to power off, wait 30 seconds, then hold the side button to switch it back on.
Charge to 100 percent and use the phone normally for a day. Fresh updates often index files in the background, which settles within 24 to 48 hours.
Check for a newer iOS build under Settings, General, Software Update. Install any minor update, since Apple often ships drain fixes shortly after a release.
If the heat and drain continue, go to Settings, General, Transfer or Reset iPhone, Reset, then Reset All Settings. This keeps your data but clears network and system preferences.
As a final step, back up to iCloud or a computer, then restore the iPhone and set it up again. If it still overheats, contact Apple Support for a battery check.
Tips and common mistakes
If the phone is too hot to hold, unplug it and let it cool before charging again, and never charge it under a pillow or in a hot car.
Low Power Mode is a fine stopgap while you track down the culprit app, but it slows background refresh and mail fetching.
Avoid installing the iOS 27 beta just to escape the drain, since beta builds often bring new bugs and are hard to roll back.
Reset All Settings signs you out of Wi-Fi networks and resets alarms and wallpapers, so note those down first.
Questions
How long does it take for battery life to settle after an iOS update?
Give it one to two days of normal use. The phone rebuilds indexes and caches after an update, which uses extra power and can make the case feel warm.
Should I turn off Background App Refresh completely?
Not usually. Turning it off for the few apps you rarely open is enough, and keeping it on for messaging and maps avoids missed notifications.
Will the iOS 27 beta fix the battery drain?
It might, but beta software often introduces new problems and is meant for testers. Only try it if you have a backup and can live with bugs for a few weeks.
