The Disadvantages of a Standalone smartwatch
There are a lot of benefits to the standalone smartwatch. They cost more compared to a regular tethered smartwatch but they have a lot of benefits that is not available in support smartwatch. But one of the main disadvantages of the standalone smartwatch that until now we see a very little improvement is the battery life.
Standalone smartwatches have a short battery life, they only last up to 2-3 days with normal usage. And about a day with call and messages activated, and less than that when GPS is used extensively. There are other models that implement options such as watch mode to give it more juice, but so far still far from the usual support smartwatch.
Low waterproof rating, this is another issue with standalone smartwatches. This is especially to smartwatches with a removable SIM card. If you want a good full waterproof version, a smartwatch with eSIM and preloaded SIM is much better.
