The upcoming Pixel Watch 4 has just had its full specifications leaked online, and it looks like Google is addressing major pain points from previous generations. The latest smartwatch will sport a brighter display, alongside a new dual chip setup for better efficiency and responsiveness. But these are just some of the upgrades, so here’s everything that was revealed.
Pixel Watch 4 Specs Leak: Brighter Screen, Better Battery, & New Chip
The big leak arrives from an AndroidHeadlines report. Google is expected to unveil the Pixel Watch 4 alongside its highly anticipated Pixel 10 series of flagship smartphones on August 20. The latest report shares a detailed list of all its specs and features, which confirms the same Snapdragon W5+ Gen 1 chip that also powered its predecessor.
But what’s improving this year is the dual chip design that brings a secondary M55 co-processor. It is faster than the M33 co-processor from last year. The upgraded co-processor is expected to help in offering faster AI performance, enabling the Pixel Watch 4 to handle 5 times the workload. So we can expect Gemini AI to be making its way to the Pixel Watch 4.
This setup is expected to bring a notable improvement in the battery life. The smaller 41mm model is getting a bigger 325mAh cell (up from 301mAh), while the 45mm variant is getting a bigger 455mAh battery (up from 420mAh). The report claims that the 41mm Pixel Watch 4 may offer up to 30 hours of battery life with always-on display enabled or 48 hours with the battery saver mode.
Meanwhile, the 45mm model brings a longer 40 hour battery life with Always-on enabled and 72 hours in battery saving mode. Another quality of life change is that Google will finally let users side charge their Pixel Watches, allowing the smartwatch to be used in a dock and have it charge while acting like a bedside clock. There are also various sensors for SpO2 blood oxygen mapping, heart rate tracking, a compass, multipurpose sensors that work with the ECG app, an altimeter, a gyroscope, UWB (ultrawide band), a barometer, and more.
Google is expected to unveil the Pixel Watch 4 during the Made By Google event on 20th August 2025, with pre-orders likely kicking off on the same date. On the other hand, wider release should follow on August 28.
