I have been using an Apple Watch for a few years now. I got my first Apple Watch (Series 4, aluminium) in 2018 but gave it to the wife after using it for a few months because of the abysmal battery life & I didn’t like how it looked. Got one again in 2020 (Series 4, Stainless Steel) and have mixed feelings about it

What I like about the Apple Watch

1. The integration with the rest of apple’s ecosystem is amazing. Everything “just works”. Setup and use are both pain free, like every Apple product.
2. The cellular functionality is awesome. I leave my phone at home when walking the dog or going for a run. Can take/receive calls if needed and stream music. It is also impressive how so many carriers support it.
3. The “Activity” app and the concept of closing the 3 rings is very good. Much better than tracking steps only.
4. Walkie-Talkie is a fun & useful feature. I use it with the wife’s watch very often. The related feature of “intercom” to send messages home is also useful.
5. Apps are very useful. Some apps even have full functional parity with their phone counterparts, although I don’t use many apps on the watch.
6. Heart Rate tracking is one of the best in the business. Once I even got alerted when I was high and my heart-rate went up while I was still.
7. The glass (on the stainless steel version) is very durable. Not a single scratch in a year.
8. The Solo braided loops are the most comfortable & convenient watch straps I have ever used.
9. Amazing obsolescence. Apart from new sensors, you would be hard pressed to find a difference between different generations of watches. Each generation gets OS updates for at least 3/4 years.

What I don’t like about it

1. The battery life is abysmal. I can’t even go away for a night without worrying about the watch dying. Once I even had to charge it between 2 connecting flights.
2. I don’t like how it looks. To me, it looks quite like a burn blister on the skin. I much preferred the Withings smart watches in this regard. They were just beautiful.
3. Every new app installed on the phone gets notifications enabled by default on the watch. Can sometimes be annoying.

My watch is now almost 3 generations old already and I plan to get the 2021 model when it is out. If nothing else, I hope it has a better battery life than the current ones.
