Earlier this year, new Wear OS 4 devices started claiming up to 100 hours of use thanks to a new “hybrid interface.” According to a new leak, the Pixel Watch 3’s battery life will remain the same.
According to the retail materials of Android titlesThe 41mm and 45mm Pixel Watch 3s claim to offer “24 hours of battery life with an always-on display,” which is the same as the Pixel Watch 2.
However, the product comparison mentions “up to 36 hours with battery saving mode,” while last year’s wearable didn’t make a similar claim.
We should keep in mind that the PW3 has a noticeably brighter display at 2,000 nits peak brightness, while even the 41mm model gets a “10% larger display than the Pixel Watch 2.” (On the 45mm, it’s “a 40% larger display.”) The Pixel Watch 3 is expected to use the same Qualcomm Snapdragon W5 chip. Elsewhere, Wear OS 5 includes power optimizations, and Google previously said that “running a marathon consumes up to 20% less power” compared to Wear OS 4.
The Wear OS hybrid interface uses an application processor (AP) and a microcontroller unit (MCU) in a dual-chip architecture. As a result, Google touts “fundamental design changes to the platform” that improve performance and power. More tasks can be offloaded to the lower-power MCU, including displaying the watch face and tiles, processing sensor data, and threading notifications from your phone, as well as sorting alerts and quick replies.
However, the Pixel Watch has used a coprocessor from the start to measure heart rate per second.
Meanwhile, there is a “20% faster charging” when comparing the 41mm PW2 and PW3. This is “charging speed” [is] Based on testing with fully depleted device batteries, “with USB-C charging cable with contact pins unchanged from last year.
