How to downgrade iOS 26 to iOS 18.7 on iPhone SE (2022)?

Can I downgrade my IOS to 18.7? My 2022 IPhone SE has been having a lot of battery life issues since IOS 26. I’ve been trying to figure out how to prevent these issues, such as using low power mode, and clearing up my memory. The battery still drains fast, and I really want to downgrade my operating system. Does anyone know how to do this?

Hello,

Downgrading is not possible. It wouldn't solve your battery issues anyway.

Follow these standard steps for short battery life: 

1) Have you tried a restart?  If not, do it now.

2) Go to Settings > Battery > BATTERY USAGE BY APP to see the apps that are consuming your battery.

3) Check “Battery Health” in the link: 

iPhone Battery and Performance

4) If all else fails, consider a battery replacement:

iPhone Battery Service

Good luck.
