I'd say 90 days of constant use would be a good measure of the new Apple Watch. It was a great birthday gift surprise from my girlfriend and I hopped right into the habit of using it. Most days I would wear it out and around at work appointments and for different workouts. This is what I found...
- The battery lasts a full day, and it charges quickly. The USB cable it came with magnetically attaches to the watch. If I wanted to recharge and "top off" in the middle of a day, it did so very rapidly. When I was in "workout" mode, it definitely used battery power more aggressively.
- I never used it in a pool, but it has been on some very sweaty workouts of riding or running. Accuracy is claimed to be better when you carry the iPhone also, which I don't often do. Using the GPS feature in the Apple Watch alone yields a generous interpretation of distance. I'd run a mile, the watch would say I went 1.1 miles. Oh well, I'm not a stickler for exact mileage or times.
- I really use the haptic (tapping sensation on your wrist) features with notifications. When I receive texts, GMail, Slack or WeatherChannel alerts, I glance down at my wrist and see what's happening. IT works for incoming calls, a few times I took the call or listened to a voicemail on the watch. It's not loud, but it works to my satisfaction. Texting and voice capture (Is Siri in there, too?) works well on the device. When I put my car's bluetooth on and paired with my watch, the Siri connection was garbled and it messed up easy statements. I don't believe that's a function of the watch, that's probably the VW Beetle from 2012 interacting with my iPhone 6.
- I do change the watch faces quite often - I use the "COLOR" watch to match my clothing. I usually do this as a demo for someone that hasn't seen an Apple Watch. Soon, I believe in Fall, we will be able to incorporate our photos into a watch face. That will be cool!
- I have used it as an alarm clock - VERY NICE! When I want to wake up early on a Saturday am and it's a late sleep-in for my girlfriend, I wear Apple Watch and it does its thing nicely. I wake up and leave the bed while she gets to sleep, no alarm or sound of an iPhone skipping around on a nightstand! This is another feature expected to improve and operate independently of the iPhone in WatchOS 2.
- I do find myself checking my heart rate every once in awhile, that's a neat feature.
- I loaded Shazam! music capture app, I've only caught a few songs with the Watch app, but it does work.
- I would be interested in trying a metal band, the method by which you swap bands is very simple. Apple has a few, but I'll wait for good thrid party bands to surface. I spoke to an Apple Store Genius who said one guy came to the store with a watch that had a cheap third party band stuck in his watch. They couldn't get it out at the store, his watch had to be sent back for service.
I'm a happy Apple Watch user! I know the next release of software opens up the processing power of the watch so as to be more independent of the iPhone - that will lead to nice new possibilities. I will keep an eye on nice metal bands and I'm always chatting with the Apple store and Experimac folks about new and useful apps. The Apple Watch is a winner for me!
