Fix iPhone 17 Running Slow: 8 Quick Solutions to Regain Speed Fast

Part 1. Why Your iPhone 17 Running Slow Could Happen

Before you resolve the iPhone 17 lagging issue, adhere to the listed reasons that are causing it in the first place:

1. iOS 26 Bugs: There is a chance that the installed iOS 26 firmware has bugs or system-level errors. These issues can cause sluggish animations, slow keyboard response, and overall lag.
2. Compatibility Issues with Apps or Features: Many applications may not be fully updated or optimized for iOS 26. This is why they may crash, freeze, or feel glitchy, while newly introduced iOS features can also cause temporary compatibility issues.
3. Background Apps and Heavy Usage: If you are running too many applications at once, it can use up RAM and processing power. Not just that, if features like Background App Refresh are enabled for many apps, it can also slow down the performance of the iPhone 17.
4. Network and Connectivity Problems: Internet-dependent applications may also slow down the pace of the app and the phone because of unreliable Wi-Fi and mobile connections. When your iPhone 17 cannot reconnect to networks, it consumes additional resources, which further decreases performance.
5. Heating and Throttling: When your iPhone 17 overheats, it deliberately slows down the processor to prevent damage. This can happen during long gaming sessions, continuous video streaming, or using heavy apps.

Part 2. Quick Fixes to Speed Up Your iPhone 17 Running Slow Without Losing Any Data

To resolve the iPhone 17 lagging issue, here are some of the basic and innovative fixes that you can consider:

Fix 1. Close Background Apps

Try to close all the background applications, as this makes iPhone 17 run faster by force-closing the frozen, glitchy, and battery-draining apps. Additionally, closing heavy apps like games and video editors can free up some RAM and briefly improve responsiveness. Doing so via illustrated steps can reduce unnecessary background refresh, saving data, battery, and system resources when apps constantly sync content:

Instructions. Swipe up from the bottom of your iPhone 17 screen and swipe up the app that you seek to close.

Instructions. Pick the "Battery" option from iPhone 17 settings and scroll down to turn off the "Low Power Mode" option.
