> i did the test on s3 mini and the difference is huge
A quick look-up shows that the S3 Mini is over 7 years old. That's absolutely ancient for phones, and I'm sure the vast majority of devices in active use are much newer. For example Apple now show separate iOS usage stats for devices released in the past 4 years, which I think covers most active usage.
so no more support for old devices ? forcing marketing to always buy new phones
what about kids or young people who have cheap phones (not much powerful or old 32 bits phones)?
