Installing a software update can temporarily slow your phone due to background indexing. Apple and Android reindex data after updates, causing CPU spikes and battery drain. This process can take hours or days, especially on older devices.
Newer phones handle updates better due to more efficient chips. Major updates are designed for newer hardware, so older phones may struggle with new features and animations. To speed up your phone, keep it plugged in and on Wi-Fi during indexing.
Reboot, update apps, and free storage space. Check battery health—poor batteries can trigger slowdowns. A factory reset or downgrade may help, but hardware limitations may persist.
Contact the manufacturer if issues continue.
