After the update my device is very slow. Battery draining very fast and have many lag issues and mostly i noticed the lag when i am adding a new wallpaper and also in control centre. Hope apple fixes ASAP.
iPhone 12, iOS 26
After an update, particularly a major release like iOS 26, its common for your iPhone to drain more battery temporary as it needs to index all your data and files for search and other tasks such as updating apps and downloading new assets. Give it a few days to fully complete its post-update processes and the battery drain should go back to normal levels.
Regarding your lag, try a Forced Restart. This is a good thing to do after every iOS update to ensure things run smoothly after updating.
Don't let go or react to the Power Off Slider. It can take a few tries. Hold for up to 30 seconds.

Re" Battery drain and Lagging issue after ios 26 update on iphone 12
Seems your iPhone is busily indexing and working in the background immediately after an update, so that everything will soon be in order for you to use smoothly.
The way I understand it: You won't need to do anything beyond keeping iPhone charged, and allowing the process ample time to complete.
