Some owners of the original Pixel Watch and Pixel Watch 2 reported unusually rapid battery loss after Google’s June 11, 2024 update. The timing and volume of complaints make a post-update regression plausible, but Google’s release notes did not acknowledge battery drain as a known issue, and the available evidence does not show that every watch—or even every affected watch—had the same cause.
What the June 2024 update changed
Google began rolling out the update on June 11, 2024, for both Pixel Watch generations. It was a Wear OS 4 release with a June 5 security patch. Google listed build TWD9.240605.001; contemporary rollout coverage also identified TWD9.240605.001.A1 for global devices.

The official announcement focused on improved on-wrist and off-wrist detection (including for some users with wrist tattoos), Car Crash Detection through the updated Personal Safety app, improved bicycle-fall detection, security fixes and performance changes. Battery drain was not listed as a known issue. See Google’s June 2024 announcement and the contemporary update coverage.
What owners reported
Beginning soon after the rollout, users on Google’s support forums and Reddit described battery behavior that was substantially worse than before. Reports included:

- Problems on both the first-generation Pixel Watch and Pixel Watch 2.
- Temporary improvement after a restart or factory reset for some users, with no improvement for others.
These are user observations, not controlled measurements or a failure-rate survey. The June 21, 2024 report and the Google support discussion establish that owners experienced the symptom, not that the firmware definitively caused it.
What is confirmed—and what is not
| Claim | Evidence status |
|---|---|
| The update started rolling out June 11, 2024 | Confirmed by Google |
| The original Pixel Watch and Pixel Watch 2 received it | Confirmed |
| Some owners experienced rapid drain afterward | Reported by users and contemporary coverage |
| Every Pixel Watch was affected | Not supported; many owners reported no change |
| Car Crash Detection caused the drain | Unproven |
| The July update fixed the problem for everyone | Not supported |
| A factory reset is a guaranteed fix | Not supported |
Google’s announcement contains user comments about battery loss, but those comments are not an official diagnosis or a commitment to a June-specific fix. Reports after the July update were also mixed: some users said battery life improved, while others continued to report severe drain in the July community discussion.

Why the same update may produce different battery results
LTE and signal strength
An LTE watch can consume considerably more power when reception is poor or it repeatedly searches for a network. During testing, set Settings → Connectivity → Mobile → Mobile → Automatic or Off when Bluetooth or Wi-Fi is available. Google’s battery guidance identifies cellular connectivity and weak signal as important variables.
GPS and streaming
Continuous GPS workouts and music streaming are high-drain activities. Google estimates approximately 8–10 hours with continuous GPS use, so a GPS-heavy day is not comparable with a light-use day.

Display, safety and health tracking
Always-on Display, sleep tracking and safety sensors can change consumption. Some users associated better endurance with disabling Car Crash Detection or fall detection, but that remains anecdotal and reduces safety functionality. Treat it as a short diagnostic test, not a proven permanent solution; one Reddit discussion is available at this thread.
Battery age
The original Pixel Watch launched in 2022. Battery capacity naturally declines with age, heat and charging cycles, so an older battery may have reached its limit at the same time as the update. Timing alone cannot distinguish aging from a software regression.

How to test and troubleshoot the drain
- Measure a fixed period. Record the starting and ending percentage, elapsed time, model and LTE/Wi-Fi type. Note Always-on Display, GPS workouts, music streaming, sleep tracking, safety features and cellular signal. Google’s approximate figures are up to 24 hours for the original Pixel Watch with Always-on Display off and up to 24 hours for Pixel Watch 2 with it on; they are not guarantees.
- Restart the watch. Hold the crown for about three seconds, scroll down and tap Restart. If it is unresponsive, hold the crown and side button for about 35 seconds, until the Google “G” logo appears. Follow Google’s restart instructions.
- Change one high-drain setting at a time. Turn off Always-on Display, use Bedtime Mode overnight, enable Battery Saver temporarily, and set LTE Mobile to Automatic or Off when a phone connection is available. Avoid GPS and streaming while comparing results.
- Update companion software. Install pending watch-firmware, Google Pixel Watch app, phone, Fitbit and watch-app updates. Synchronization or app installation can temporarily increase activity, but this is a troubleshooting possibility rather than a proven explanation for the June complaints.
- Run a cautious safety-feature test. If you choose to test Car Crash Detection or fall detection, record the setting and duration, then restore it if there is no clear improvement. Do not assume a user anecdote proves causation.
- Factory-reset only after backup. On the watch, use Settings → Disconnect & reset → OK. From the phone, use Google Pixel Watch app → System → Reset and unpair watch. A reset erases apps, settings and watch data; pairing again may require the previous PIN or Google Account credentials. It may not correct a firmware regression, cellular behavior or a worn battery.
When to contact Google or consider replacement
Contact Google Pixel Watch support when severe drain continues after a restart, controlled settings tests, software updates and—when appropriate—a single reset. Include:
- Watch generation and LTE or Wi-Fi/Bluetooth configuration.
- Firmware build and the date the drain began.
- Battery percentages with exact time intervals.
- Screenshots and the settings used during testing.
- Whether a reset changed the behavior.
Persistent rapid loss after a reset points away from a simple corrupted local setting, but it does not by itself identify firmware, hardware, network or battery health as the cause. On an older watch, Google support can determine whether service or replacement is appropriate before you buy another device.

If charging itself appears incomplete, inspect charger alignment and contacts before blaming software. Charging accessories differ by generation; consult Google’s charging guidance. For connectivity-specific checks, use Google’s connectivity help.
Verdict
The June 2024 update coincided with a credible cluster of battery-drain complaints involving both Pixel Watch generations. The public record supports describing this as a reported post-update regression—not as a universally confirmed bug. Measure the loss, isolate LTE, GPS, display and safety features, restart and update before resetting. If the problem survives those steps, battery aging or hardware trouble becomes as important to investigate as the firmware.
