It’s interesting to note that the lab’s wireless charger is only rated at 10W (5V at 2A). Newer versions are expected to employ higher-capacity batteries than the Watch4 generation (and predecessors) (in our tests the Galaxy Watch4 needed about an hour and a half). Keep in mind that this is only the charger’s maximum output rating of 5 watts, not the input.
Fast charging or not, the batteries will be larger: the Galaxy Watch5 will feature 276mAh and 397mAh batteries in the 40mm and 44mm variants, respectively, while the Watch5 Pro will have a 572mAh battery.
Ice Universe confirms that the Pro model will not have a rotating bezel. Even more anger was voiced by the leaker with regard to design; reportedly, there will be a little bezel around the display whose colour does not match the active part of display.
They have Bluetooth (2.4 and 5 GHz, b/g/n), Wi-Fi (2.4 and 5 GHz, b/g/n), and NFC. There should be LTE-enabled watches as well. As the launch date for the watches in August approaches, more information should become available.
