What Redditors Say
Best praise vs top criticism for OnePlus Watch 3
Best Praise
+6 pts“WearOS offers a lot as it really makes the watch into a tiny smartphone. But it has its costs to offer that. A simpler OS (as Tizen was) is really more suited for these relatively small devices with (compared to full smartphones) tiny tiny batteries - for obvious physics reasons with current battery tech. That is why the OnePlus watch 3/2 solution of offering dual boot is so smart an idea. Work with a more primitive but much leaner OS normally AND offer you the option to boot into WearOS when you need the fancy stuff. Or the other way round: Use with WearOS when frequent charging is not a problem, and boot into the leaner OS when you prefer prolonged stamina. IMHO **all** fancy smartwatches *ought* to have the option to dumb down so it was never more power-hungry than needed for the user's selected active features.”

+2 pts“Unfortunately none of the werOS watches offer a reasonable battery life. The least bad is the 46mm variant of the oneplus watch 3, as it offers to boot into an OS more suited a smart watch, while not an strictly need of fancy WearOS features (the model 2 does offer dual boot as well as do the 43mm variant watch 3 with a lesse bettery)”

+2 pts“Yeah Fenix 8 is top, but Venu 4 is close to the top. Some differences: F8 has maps on board, V4 not. F8 is dive certified, has a depth sensor, V4 not.”

+4 pts“No. Fenix doesn't have either SIM or eSIM support so it can't make phone calls without a phone. Garmin's LTE is not for that.”
