    Apple Watch pros/cons as well as Garmin comparison

    I just got the Apple Watch and I like using it as a secondary cellular device: being able to see/feel/hear messages and phone calls come in while your phone is in your pocket or your phone is left at home. I also like that you can talk and send messages on the Apple Watch. The battery life is good when you use it for these things but when you use your Apple Watch for workout purposes or directions on maps, it depletes the battery relatively quick and you have to charge it again mid-day/evening. If you are an outdoors person and use your watch for hikes, workouts, directions, retracing your steps, etc and don’t care about being able to send messages back on your watch. I would recommend the Garmin. You can get a notification of a call or message but you can’t send anything back. You also have to have your phone pretty close to you for the phone and watch to connect. But The battery life on the Garmin is awesome. And last days to weeks. I think the max battery life I’ve had on my Apple Watch has been half a day to a day when I workout and maybe a day and a half to two days when I just use it for messages/phones calls. Hoping they can compete with the Garmin for battery life. Overall I like the watch up until probably a new watch comes out and Apple bugs my current one to make me buy a new one.

    Apple Watch series 9

    I wanna start by saying I have never been a watch person. I was skeptical at first. I did want something I could gesture for help if I was ever in a situation where I needed to get help fast. I like the watch more and more over time. Personally, I keep the screen on 15 sec time out. Why? Well, simply, why does it need to be on all the time wasting battery for no one to see? I gave it 4 and not 5 stars; because while it has many uses and I’m glad I have one for many things: notifications especially, time, finding my phone or iPad or keys. If I lose my phone hiking, I can still make calls from the watch and find my phone. I didn’t give it 5 for a few reasons. A little over priced for a watch considering it’s limited(practical, and ergonomic) usefulness, at least in my opinion. Siri dictation needs to be stellar at understanding me, due to the fact the keyboard isn’t the easiest thing to use, and it isn’t quiet at that level of interpretation yet. Over all it could be a more classic round design and prettier and that’s is why I give 4 out of 5.

Questions & Answers
  • What's the difference between GPS and GPS+Cellular?

    The Cellular allows you to add it to your cell plan. For an extra fee, like 10.95 a month or similar, you can use your Apple Watch as a phone when you are not near your iPhone. For example, you could go out for a run and still use your watch as a phone. Of course this only works if you add it to your cell plan. My sister-in-law has the cellular version and plan but rarely uses it. Some parents want the ability to call their kids but don't want them to have all the cell phone functionality, so a cellular enabled Apple Watch is a great option.

  • is this new watch able to use other watch bands that I have that I used with my series 3

    It can not

    Answered by TomariA
  • Is this watch compatible with an iPhone X?

    Yes, I currently have the xr but you'll need to update your phone to the lasted iOS update. Which will probably slow your phone down but so far it's been good with my watch. However I am looking into upgrading my phone as well.

    Answered by BriannaL
  • Is it compatible with T-Mobile

    I use T mobile. There was a problem setting up the cellular service on the Apple Watch with T mobile. They have many poorly trained people at Tmoble. I finally found a smart tech lady who set everything up. It’s easy if you what to do.
