My iPhone 14 battery used to last all day but now it dies by 2 PM. I have not installed any new apps. What changed?

Several things could cause sudden battery drain. First, check your battery health: go to Settings, Battery, Battery Health and Charging. If Maximum Capacity is below 80%, the battery itself is degraded and Apple will replace it for $89. If battery health is fine, check which apps are using the most battery: Settings, Battery, scroll down to see battery usage by app. Look for anything unusual consuming more than 10-15%. Common culprits include a rogue app running in the background, Location Services being used constantly (check Settings, Privacy, Location Services), Background App Refresh running on too many apps (turn it off for most apps in Settings, General), push email checking too frequently (switch to every 15 or 30 minutes instead of push), and widgets on your home screen that update constantly like weather or news. Also check if you recently updated iOS because some updates have battery bugs that get fixed in the next point release. Restarting the phone after an update helps recalibrate the battery gauge. As a quick fix, turning on Low Power Mode (Settings, Battery) can nearly double your battery life by reducing background activity.
