the claim

Frequent charging damages a lithium-ion smartphone battery more than charging it less often.

the verdict
CONTESTED PARTIAL
Recorded sources
2 sources for · 1 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that frequent charging damages a lithium-ion smartphone battery more than charging it less often?

Partly. One battery-cycling source indicates shallower, less frequent cycling extends lithium-ion cycle life, while another says a full phone battery stops charging so frequent plugging causes no overcharge damage; neither directly compares frequent versus infrequent charging of a smartphone battery.
