How long do wireless keyboard batteries actually last?
Reviewer consensus
It varies dramatically by design. Basic 2.4GHz combos like the MK270 are rated for up to 36 months on AA batteries per the manufacturer, and verified-purchase reviewers broadly confirm multi-year life. Rechargeable backlit boards like the MX Keys S last roughly 10 days with backlighting on and several months with it off. Apple's Magic Keyboard is rated around a month per charge.
