Smartwatches are getting better and more personal each year. They are more attached to us and portable than mobile phones. And now that they come with a calling feature, their owners don’t always have to pick up the phone to make or attend calls. These days, smartwatches with LTE connectivity or eSIM like the Apple Watch Series 8 let you make or take calls even when the phone is not connected or in proximity. However, you must ensure the watch has enough battery to power long calling sessions. Say, something like the Apple Watch Ultra or a Samsung Galaxy Watch 5 Pro comes to our mind when we talk about smartwatches with both calling functionality and large batteries. Well, those aren’t your only options as the following list will tell you. You get a calling option on watches from different budgets, but of course, not all of them work the same. Apart from a premium few, most smartwatches feature Bluetooth Calling, which means your watch must be tethered to the phone via Bluetooth. Even in those, some only let you take calls and not make them.
Apple Watch Ultra comes in an eSIM model also. It comes with a 542mAh battery that claims to run 36 hours in total. However, the Apple website notes you can get up to 2.5 hours of talk time from an Apple Watch Ultra (Cellular + GPS model) when connected to LTE. Other variables like the cellular network, signal strength, etc also come into play.
Rest, you get aerospace-grade titanium build, sapphire crystal glass display, dual-frequency GPS, car crash detection, emergency SOS, both GPS and more.
Samsung Galaxy Watch 5 Pro is equipped with a 590mAh battery that claims to run for 80 hours or just over 3 days on a single charge. Samsung hasn’t quoted the talk time hours. But, it should also last similar if not more than the Watch Ultra’s estimates.
Among other things, you also get a durable build with a titanium alloy chassis, sapphire crystal glass screen, and IP68 dust and water resistance. Then there is GPS routing, sleep analysis with snoring detection, swimming and several other activity modes, a way to know Body Fat Composition as well.
Google Pixel Watch also features LTE connectivity but has got a relatively smaller battery size of 294mAh. Even though Google claims a 24-hour runtime out of this battery, that’s subject to a lot of conditions. The real-world results would be thus far from Google’s figures, just so you know.
Besides the calling capability and conservative battery life, you are getting Wear OS with the full gamut of Google apps including Google Assistant, Fitbit fitness modes and features, GPS tracking, etc.
Now, the following watches don’t bring the eSIM-based calling capabilities. So, there are two ways to go about this. One we could take a look at smartwatches that are otherwise pricey and packed with features, and comes with only Bluetooth Calling option. Or, check out the lower-end smartwatches that get you Bluetooth Calling without costing a lot. We are taking the first route.
