So I got an Apple Watch Series 10 on launch day last year. I upgrade my watches every 3 years usually, unless there's a massive enough change like the Series 4. I've owned the S2, S4, S7 and now S10. The Series 7 was the first one to get a charging speed increase, let's call it Fast Charging 1.0. I used fast charging during its entire lifetime and I recall it reaching battery health of 90% after just 1 year and then I thought that fast charging had really hit my battery hard because my Series 4 had 86% battery health after 3 full years of use (which didn't have fast charging). I proceeded to use fast charging considering it was already too late to save that battery and I figured I'd stop using fast charging with my next Apple Watch, my current Series 10. In 2023 however, 2 years into owning my S7, Apple replaced it because of a bluetooth issue. At that stage it had reached 87% battery health, which is a faster degradation than with my S4. So I got a new battery with the replacement unit and when I got my S10 in September 2024, my 1 year old S7 replacement was at 90%, same stage as my first unit after 1 year (I had also kept using fast charging with the replacement unit knowing I'd be getting the S10).
So with my S10 99% of all charges are with the slow USB-A charging cable in a 5w Apple wall adapter, because I had seen the S7's battery degrade way too fast and the S10 got even faster charging (Fast Charging 2.0) so I thought that I wouldn't want my S10 to have 80% health after just 2 years. The other 1% charges are with the fast one when I really needed to juice up fast. I'm disappointed to see its health is already at 92% (it was at 93% when it was exactly 1 year old a couple of weeks ago). What I find super strange is that battery health seems to stay at 100% for an eternity, but once it starts dropping, it drops like a fly. I recall it dropping to 99% around April, it then dropped another 1% just 3 days later, another couple of days later it's at 97%.
So I wanted to know about other Apple Watch Series 10 owners:
- how are you charging your Apple Watch (fast charger or slow USB-A)?
- how's the battery health?
- how fast has it been dropping? Also like a fly?
