OnePlus Watch 2 Launches With Wear OS 4, 100-Hour Battery (9to5google.com) 14

Almost 3 years after launching the first OnePlus Watch, the Chinese smartphone company is launching a successor -- this time powered by Wear OS 4. Utilizing a "hybrid interface," the OnePlus Watch 2 is able to offer 100 hours of battery life, or just over four full days of use. 9to5Google reports: To achieve that goal, the OnePlus Watch 2 actually runs two separate operating systems. Wear OS handles things like apps and watchfaces, while a RTOS powered by a secondary chipset handles more lightweight tasks. A "smart mode" on the watch allows the watch swap back and forth between its two operating systems and two chipsets. Wear OS is powered by the Snapdragon W5 Gen 1 and it is Wear OS 4. The RTOS is powered by a BES 2700 MCU Efficiency chipset.

Switching between the two OS's is something you're likely to not even notice, OnePlus claims: "The BES2700 Efficiency Chipset runs RTOS and handles background activity and simple tasks, while the Snapdragon W5 handles more demanding tasks, like running your favorite Google apps. This optimized approach, enabled by the Wear OS hybrid interface seamlessly managing the transition between chips, means users will experience a smartwatch that effortlessly does it all while extending the time between charges."

Powering the Watch 2 is a 500 mAh battery which features 7.5W charging with a special charger that connects to a typical USB-C cable. The charger is magnetic, of course, and OnePlus claims a full charge in 60 minutes or less. The 1.43-inch AMOLED display of the OnePlus Watch 2 is covered in a slightly curved sapphire glass, while the watch chassis is built from stainless steel. You'll have the choice of black or silver colors with either black or green bands, respectively. The whole package is also 5ATM water resistant. Rounding out the main specs you'll find 32GB of storage and 2GB of RAM.
The OnePlus Watch 2 goes on sale today at $299.

    But not with the screen always on, that metric not listed. Which is the way I used all my smartwatches: I use a traditional, watch-looking display, and want it on all the time. I can glance at it anytime without playing games or touching it. People often don't even know mine is a smart watch because it "looks" like a watch (round form factor and realistic, watch-like display: Samsung Gear S3 Classic then Watch 4 Classic, silver case + silver metal link band).

    • If you want a long battery life and an always on display, check out the TicWatch Pro series. They have two displays, an unlit LCD segment display and the OLED. I get >80 hours of battery life from my ticwatch pro ultra 3.

    • Yeah, the screen is the biggest battery killer on any of them. I miss the week long battery life of the always on e-ink display on my old Pebble.
      • Yep. I wish there were a fast, bright, high-contrast color e-ink display for this type of application. It would fit well.

        Or- maybe a hybrid, since that is the topic. An e-ink underlay with OLED on top of it (or the other way around?) It could display one mostly static face when not actively used, just using almost no power at all. And then when touched or an event happens, it brings in the OLED.

        I don't mind charging every day or two to have AOD. It is just not a big deal. But, eventually, these watch

      My Xiaomi Mi Band 6 gets a couple of weeks battery life.

      It does all the smart watch stuff I want. Time, pulse, step count, and optionally notification. I would like an always on thing that looks like a watch, but this one cost me £20 so I'm not inclined to spend much to get that functionality.

  • Does this watch do Google assistant? I may consider it if it does.
  • I was tempted to get one until I read no iOS support. I want a step up from my no longer supported Skagen smartwatch, and this seemed like a good candidate until I read that it supports Android only, and only a limited subset of Android flavors. From the specs: "Only supports smartphones with Android 8.0 or later, which should also have a GMS version of 23.45.23 and above. iOS and Android (Go edition) devices are not supported." This is a good way to keep the price low.
  • I donâ(TM)t have an iWatch because I donâ(TM)t need another device that requires daily charging.

    "My wristwatch runs two different operating systems to save power" is not a sentence I ever imagined saying, but here we are.

  • Man, maybe I just don't get it because I've never used a smart watch before... but My G-Shock with Multi-band 6 (atomic timekeeping) and solar charge has a 10-year battery, display is always on, and has all the functionality I need for something I wear on my wrist. Everything else I can use my phone for, which is (usually) close by. I wear my watch because I want to be able to tell time, maybe use a stopwatch or countdown timer, and have a handful of alarms (which I use as my alarm clock too) but not be con

    • Yeah, I have a G-Shock "smart" watch that trickle charges via solar. I have the HR monitor on full time and get BT notifications. It tracks steps and blood oxygen, humidity, elevation and can connect to GPS. I put it on the charger maybe once every couple of weeks just to top off the half drained battery.
