Questions that only have an answer for the Samsung Galaxy S20 family

My Galaxy S20 is getting slow and the battery is weak.+

Both are age-related on a 2020 flagship: the battery has lost capacity, and a nearly full phone plus years of app updates slow it down. Free storage, disable always-on display, reduce background apps, and update what software is still available. A battery replacement helps runtime. It is also near the end of its major-update support, so some newest features simply will not arrive — that is support age, not a fault.

Is the Galaxy S20 still supported?+

Its update window has ended.

Does wiping the cache partition delete data?+

No.
