These 3 apps silently ruined my Pixel Watch's battery life for months before I noticed

Battery life on the author’s Pixel Watch had gradually slipped from “comfortable” to disappointing, but the culprit wasn’t hardware. The article points to three everyday apps/settings working together to drain power. The Pixel Watch Companion app handled watch faces, tiles, health data, notifications and permissions, relying on steady Bluetooth syncing; when settings caused frequent reconnects and extra background activity, the watch stayed communicating with the phone more often. Always-on health tracking, frequent heart-rate sampling, automatic syncing, fast-refresh tiles, and broad battery-optimization permissions all amplified the drain. After tightening companion-app settings, reducing tiles, and lowering health sampling frequency, the overnight drop improved noticeably.
