  • Android Health will add new running data and goals, plus Health Connect upgrades.
  • Wear OS watches will now last 20% longer during tracked workouts.

But Google also emphasized health and fitness tracking with this future update — more unexpected and certainly welcome. 

Google announced the Wear OS Hybrid Interface and Watch Face Format (WFF) earlier this year, both of which made Wear OS 4 more efficient. Wear OS 5 piggybacks on these updates, improving watches’ efficiency and adding more exciting watch face tricks. 

On the battery front, Android developers Kseniia Shumelchyk and Garan Jenkin explained in a blog post how “running a marathon consumes up to 20% less power on Wear OS 5 than on Wear OS 4” with default settings.
