I have recently installed IOS 26 on my iPhone 12 Mini. After installation, Battery health remains the same (83%) before and after installation, but the Battery is Draining abnormally faster than usual. I tried Downgrading back to IOS 18.6 using your 3utools but I cannot complete it successfully (Easy mode - SHSH error, Pro mode - cannot activate DFU mode). I have Already taken full backup before IOS upgrade. Kindly provide a solution.
hi bro, right now apple stopped signing iOS 18.6 or 18.6.2 versions. we have to wait till next iOS 18 version comes out. meanwhile, iOS 26 takes atleast 1 week time to finish its background optimisation and indexing works. then you will notice performance difference. do follow these suggestions to see some improvements too.
