Google's battery article gives the ratings and the levers. A Pixel Watch 3 lasts up to 24 hours with Always-on Display and up to 36 hours in Battery Saver, the Pixel Watch 2 up to 24 hours with Always-on, and the original Pixel Watch up to 24 hours with Always-on off; the Pixel Watch 4 and 5 last up to 30 hours on the 41mm and 40 hours on the 45mm.
Battery Saver turns on automatically at 15 percent, disables Always-on Display, keeps Tilt-to-wake, limits background activity and can delay notifications while keeping key health, fitness and safety features. Other levers: turn Always-on off, set a shorter screen timeout, use Bedtime mode at night and turn off Tilt-to-wake. Battery Defender pauses charging at 80 percent after 4 days on the charger, so an 80 percent ceiling is not a fault, and the Pixel Watch 4 and 5 have Adaptive charging. Over time Pixel software manages battery performance to maintain battery health as it ages.

Before you touch a setting
Record this first — changing settings destroys the evidence
- The model, firmware version and the battery percentage over a typical day
- Whether Always-on Display, LTE and Bedtime mode are on
- Whether Battery Saver comes on early
- How old the watch is, and how many months of use

Model-specific
What is true of this model and not of its siblings
- Models this page covers
- Pixel Watch 3 41mm (GG3HH, GBDU9) and 45mm (GGE4J, GRY0E), and Pixel Watch 2 (G4TSL, GC3G8), the two catalogd models. Google's articles cover the whole line, and its Pixel Watch, 2 and 3 use a USB-C magnetic charging cable while the 4 and 5 use a Quick Charge Dock.
- Rated battery by model
- Google's article: Pixel Watch 3 up to 24 hours with Always-on and 36 hours in Battery Saver; Pixel Watch 2 up to 24 hours with Always-on; original up to 24 hours with Always-on off; Pixel Watch 4 and 5 41mm up to 30 hours and 45mm up to 40 hours with Always-on.
- Display
- Google lists a 320 ppi AMOLED LTPO display up to 3000 nits peak with a 1 to 60 Hz responsive display on the newer models.
- Pixel Watch 4 and 5
- Google's help articles also cover the Pixel Watch 4 and 5: they charge on a Quick Charge Dock with crown up, list up to 30 hours on 41mm and 40 hours on 45mm with Always-on Display, and the Pixel Watch 5 charges from 0 to 80 percent in about 20 minutes.
- Model number instead of a part number
- No part number is involved for you. Google identifies a Pixel Watch by its model number, for example GBDU9 or GG3HH for a Pixel Watch 3 41mm, and its serial number in the Pixel Watch app and under Settings, System, About.
- Tools and supplies
- The charger that came with the watch, a soft lint-free cloth, your Android phone with the Pixel Watch app, and a pen and paper to note the model and serial number. No screwdriver is needed and the watch should not be opened.
- Repair cost
- Google does not repair a Pixel Watch 3; per 9to5Google and Android Authority it only replaces one, and Preferred Care costs $4 a month or $89 for two years plus a $49 service fee when a claim is approved. A Pixel Watch 3 launched at $349 for the 41mm, so out-of-warranty replacement is a new-watch decision rather than a repair bill.
- Other models this page answers
- These steps also fit the Pixel Watch 2.
Stop boundary
When this stops being a self-service repair
- !If the watch drains inside a day with Battery Saver on, contact Google support
- !If the case is hot or swollen, stop using it and contact Google
- !If it stops at 80 percent, it is probably Battery Defender, not a fault
