my se3 last 24hrs+ NO NEED to use low power mode im very impressed
Se 3 or s10 very good watch I have the 10 very good watch if you are not a keen sports fan
Okay naman siya for working out. Jowa ko naka-SE3. Charges it siguro once every 1.5 days, take note that she doesn't use it to track any workouts. I'd be wary sa battery life niya when doing long runs.
If you see yourself hating having to charge your watch everyday, Apple Watch is out of the options. Looks like main use-case mo ay para sa physical activities, I say Garmin.
Based on OP's choices, it seems Ultra is out of the budget and a little extreme for their use-case
i do all of that with my Apple Watch SE 3, i cant complain
Been using my 44mm SE3 Cellular for a few days. 1. Haven’t used cellular yet as my MVNO doesn’t have it yet. 2. I use my S3 at night so haven’t completely tested the battery but when I’m done with it before bed it has a solid 45% left. 3. I’ve been on the yearly upgrade train since S0, the best thing about SE3 is haven’t noticed any worse function than previous non-SE watches. Overall I’m happy so far, my plan going forward is being on the SE upgrade train.
I don’t know why, but my Garmin was bad at tracking sleep compared to my Fitbit and now my AW Se 3. I had the Lily 2, so maybe it was because it’s a cheaper model idk. It could never get my sleep times right and would say I was sleeping 9 hours every night and falling asleep at 10pm when that wasn’t even close.
