Wear OS 5 is built into all of the latest and greatest Android smartwatches. But as some Wear OS watches are stuck with versions 3.5 or 4, you may want to know what's so special about this latest software version and if it's worth the upgrade, such as battery enhancements and new AI tricks.
We'll also break down Wear OS 5.1, which began rolling out to Pixel Watches in March 2025, as well as our expectations for future features before Wear OS 6 arrives later this year.
One UI 6 Watch, the Samsung version of Wear OS 5, has its own unique perks as well. This guide will break down all of the features and changes available on both versions of Wear OS 5, from Watch Face Format to Energy Score.
We'll also explain which watches are due to receive Wear OS 5 (or already have), as well as those Android watches with no guarantee that they'll progress beyond Wear OS 4.
Wear OS 5: Eligible watches
These are the current Wear OS watches that either have received Wear OS 5 or are confirmed to receive the update:
- Samsung Galaxy Watch 7 (Launched with One UI 6 Watch)
- Google Pixel Watch 3 (Launched with Wear OS 5)
- Pixel Watch 2 (Received Wear OS 5 in mid-November)
- Pixel Watch 1 (Received Wear OS 5 same day as Watch 2)
- Samsung Galaxy Watch 6 & 6 Classic (Received One UI 6 Watch in late November 2024)
- Samsung Galaxy Watch 5 & 5 Pro (Received One UI 6 Watch in December)
- Samsung Galaxy Watch FE (Received One UI 6 Watch in December)
- Samsung Galaxy Watch 4 & 4 Classic (Received One UI 6 Watch the day after the Watch 5)
- OnePlus Watch 3 (Launches with Wear OS 5 in April)
- OnePlus Watch 2 & 2R (Due to receive it in Q3 2025)
When it comes to the best Wear OS watches, most of them have either jumped to Wear OS 5 already or are due to receive it soon.
Pixel Watches are eligible for three Wear OS updates. Google originally began rolling out Wear OS 5 to the Pixel Watch 1 & 2 in late September, only for user crashes to force a rollback. Google eventually restarted the update in mid-November, with the caveat that the next feature update won't arrive until March 2025.
Samsung watches receive four Wear OS updates, so all post-Tizen models received Wear OS 5. One UI 6 Watch began rolling out on November 19 with the Galaxy Watch 6 series, before arriving on subsequent models over the next couple of weeks.
OnePlus has explained that its watches will receive two OS updates. The OnePlus Watch 3 launched with Wear OS 5, but the OnePlus Watch 2 and Watch 2R won't receive the update until sometime between July and September 2025.
The Xiaomi Watch 2 Pro and Watch 2 jumped from Wear OS 3.5 to Wear OS 4 in September 2024 (per Techradar). We don't know if these watches will receive Wear OS 5 or not; if it does, it may not happen until the second half of 2025.
The TicWatch Pro 5, TicWatch Pro 5 Enduro, and TicWatch Pro 5 Atlas all updated to Wear OS 4 as of September 2024, well behind the rest. Like Xiaomi, we don't know of a guaranteed Wear OS 5 update or how long it would take to arrive. And Mobvoi's version of Wear OS is more limited, as it doesn't support Google Assistant.
Any other Wear OS brands like Fossil won't ever receive Wear OS 5, as they've all largely abandoned the platform.
Wear OS 5: New features
Broken down into categories, these are all of the Wear OS 5 features — or apps introduced alongside Wear OS 5 that technically work on older versions — that you need to know about!
Screen size optimization
Previous Wear OS versions showed the same content on your watch display regardless of the size; larger displays simply made certain content appear larger. With Wear OS 5, developers can reflow content to take advantage of the extra space.
Wear OS apps will "work optimally across the range of device sizes and font scales," Google explained in its initial announcement.
The photo above of the Pixel Watch 3 41mm and 45mm shows this UI principle in practice. The smaller display can only fit three sports icons, while the larger watch can show six. This incentivizes people to pay extra for larger screens, knowing Wear OS 5 actually uses the space appropriately.
Plus, Wear OS 5 added a "grid-based app launcher" as an alternative to the app list default on past Pixel Watches. Other Wear OS skins like One UI Watch already offered a grid option before, but this makes it natively available on all watches.
Battery optimizations and WFF improvements
Google's original Wear OS 5 announcement included the promise that "performance improvements" would make certain tasks use less battery life than on Wear OS 4. For example, "running a marathon consumes up to 20% less power" with the same requirements like frequent GPS and heart rate checks.
Google's Hybrid Wear OS interface may be partially responsible for these improvements. It relegates certain tasks like health sampling to the low-powered coprocessor, requiring less battery life in standby mode.
Wear OS 5 also requires watches to use the XML Watch Face Format, which shows information without battery-guzzling executable code or animations. It helps Wear OS 5 watches last much longer with the same capacity, but it also blocks apps like Facer with more creative watch faces from third-party developers. You may lose your favorite faces after this update, even if you already paid for them.
To lessen the sting of this change, Google added many more WFF options as a default for Pixel Watches. It also made them more customizable with colorful "Flavors" for each face (see the slideshow above); plus, it added new complications such as progress towards a fitness goal (like 90% of daily steps done) or "weighted elements" with a pie-chart-like summary of different related stats.
Lastly, Google added a weather complication to WFF, letting you see either the current or upcoming forecast from the main view.
New fitness tools
If you're specifically looking at stock Pixel Watch software, Wear OS 5 added a ton of running tricks. Fitbit Cardio Load and Training Load show how hard you've worked out across the past week (or month) and how much total workout time you should have to improve your fitness. You can see your Daily Readiness in the Morning Brief, create and follow running workouts with intervals, check your post-run form insights, and see your records for distances like 10K.
While Fitbit may eventually become preinstalled on Android phones, we don't know if third-party Wear OS watches will have access. So the global Wear OS 5 fitness updates are more limited.
All Wear OS 5 watches will be able to track Ground Contact Time, Stride Length, Vertical Oscillation, and Vertical Ratio for the first time, with that running form data now shareable through Health Connect.
Also, Wear OS 5 watches support "debounced goals," which is a fancy way of saying athletes can set a workout goal like "keep my heart rate between 130–160bpm for 30 minutes" and have the watch warn them after a short delay if they fall out of range.
New apps and other features
Wear OS 5 introduced some new Google ecosystem apps and functions that connect your watch with other devices. Some are Pixel exclusive; others may be backwards-compatible with other Wear OS versions. We're simply going to include all of the new apps and tools, so you're aware of them.
Recorder: This records files locally with a tap, and has a Tile available. Pixel phone owners can sync their recordings to their phone.
Google Home/ Nest controls: If you have a Nest Doorbell, Google TV Streamer, or other Home devices, you'll now be able to control or access them on your wrist. You can check your Google security camera feed or pause a movie from the watch display.
Improved camera controls: Previous versions of Wear OS had the ability to trigger a smartphone photo remotely. Wear OS 5 lets you access your Pixel Camera app viewfinder to see what photo you're about to take, as well as switch between camera modes.
Screenshot protection: Wear OS 5 adds a "privacy-preserving screenshot detection API" that ensures greater security.
Media output choice: With Wear OS 5, you can "choose which device should play media and show information about the currently-playing media content."
One UI 6 Watch
Samsung's One UI 6 Watch is based on Wear OS 5, but it chooses which features apply to Galaxy Watches, and it has its own unique features that don't apply to other Wear OS watches.
Energy score: Like Fitbit's Daily Readiness score, Samsung Energy Score judges your "physical and mental readiness" based on your "sleep, activity, and heart rate" on previous days.
Personalized AI Wellness tips: Based on your Galaxy Watch data, Samsung will send you tips on how to improve based on your priorities like Sleep, Exercise, or losing weight. These AI tricks are guaranteed free through the end of 2025, meaning Samsung may charge for the information after that.
Suggested replies: One UI 6 Watch's other AI-powered trick is to come up with auto-generated replies to your messages, so Galaxy Watch 7 owners don't have to bother with the QWERTY keyboard or voice-to-text.
Sleep apnea detection: With FDA approval for accuracy, Galaxy Watches can detect "moderate to severe sleep apnea;" this link shows how to set it up. Samsung promises this feature will come to older Galaxy Watches but is currently exclusive to the Watch 7 and Watch Ultra.
Gestures: The new Buttons and Gestures menu lets you enable three gestures: Double pinch, shake to dismiss, or knock knock. Double pinch lets you "answer calls, dismiss alerts, launch apps, control your music, and take photos." Shake to dismiss "declines incoming calls or dismiss alerts such as alarms, timers, and reminders." Knock knock opens your favorite app.
Workout Routine and Race: With Wear OS 5, Galaxy Watch owners can now race their past times or create a custom multisport workout.
Wear OS 5.1
Google announced the Wear OS 5.1 developer preview in late November 2024, then finally began rolling out the stable version in early March 2025. Based on Android 15, 5.1 made two backend changes: the Credential Manager API and Watch speaker playback.
The first new feature ensures that your watch will remain signed into apps with the Restore Credentials function after restoring a watch, and generally keeping your passwords synced across devices. The second feature lets apps use the watch speakers for functions like sounding an alarm or reading out fitness guidance during a workout, in case you don't have Bluetooth earbuds connected.
Google's March community post runs through several front-facing changes with Wear OS 5.1. For starters, they updated their steps algorithm for "challenging situations" like "pushing a shopping cart, navigating in a wheelchair, or going on walk/run with a stroller" where steps aren't as obvious.
Fitbit will change menstrual health tracking to make it easier to "log periods, view your current cycle status, and see predictions for your next period."
Pixel Watch 2 owners finally get Auto Bedtime mode to match their sleep patterns, matching the Watch 3.
And Google has changed media controls to "make it easier to control audio content from the watch with control types based on content being played (such as Podcasts within YouTube music)."
Early Wear OS 5.1 users also report subtle aesthetic changes like a new accent color and watch face changes, as well as new developer options. But since we haven't received the update yet, we can't describe them for ourselves. The update should finish rolling out to Pixel Watches before the end of March.
Future Wear OS updates
In its Wear OS 5.1 announcement, Google said that "our next planned update will target June 2025, and quarterly thereafter." It appears that Google will leave behind its typical monthly updates and stick to a slower schedule with more substantial feature updates before Wear OS 6 in September.
In terms of what new Wear OS features are coming, we've heard a credible rumor that Gemini will replace Assistant on Wear OS. This is such a significant change that it probably won't arrive until Wear OS 6.
Recently discovered Pixel Watch code indicates that Wear OS will add adaptive charging to preserve your watch's capacity over time; again, we don't know if this will come to Wear OS 5 watches, or only Wear OS 6 watches.
Otherwise, we can only wait and see! But there are still plenty of Wear OS watches still waiting for Wear OS 5 and new features still to come.
