Do Apple Watch batteries wear out after a few years? My V4 watch,purchased two years ago, is not holding charge as long as it used to do. Charge easily lasted for more than one day. No longer. lucky if I get thru the regular 6:30 A M to11:00 pm day

My Vs4 apple watch , now two years old is no longer holding charge as long as previously

Formerly, a charge lasted more than one day.. sometimes two days. Now, by late afternoon or in early evening I get notified watch is using reserve

OR, I have been startled, at night (circa 11:00 PM) When I put my watch on the charger, I see red instead of the usual green- telling me, again, that the battery is low.

Charger is plugged in -

Is this normal? Is the watch supposed to wear out in a couple of years?

OR, Do the chargers wear out?
