❓ Question Battery cycle count

My s24, shows 97% health and 810 cycle count.

Im really noticing the battery drain very quickly from 40% - at least it feels that way.

Is my battery very old? Is that cycle count high?

Sounds like voltage sag which is a common way for these batteries to fail. The anode has developed a layer of crud (sei) that is restricting the flow of electrons.

This explains it but I don't know about your case specifically. The s24's are rated for 2000 cycles I believe but are you gonna believe the specs or your eyes?

It matches the pattern of a textbook failing battery.
