Tech giants are fighting over the smartwatch market, and Google is slowly carving out its own space with the Pixel Watch series. The Pixel Watch, which came out in 2022, was Google’s first wearable device. It combined Fitbit’s health-tracking skills with Google’s software skills. As we get closer to the expected release of the Google Pixel Watch 4 in August 2025, leaks and rumors give us a picture of a device that improves on its predecessors while adding useful new features. This article goes over everything we know about the Pixel Watch 4, including its design, hardware, software features, health-tracking abilities, and how it might affect the competitive wearable market.
People love the Google Pixel Watch series because of its simple, sleek design, which includes a round, domed display and a body made of stainless steel. According to leaks from trusted sources like OnLeaks and 91mobiles, the Pixel Watch 4 will keep this classic look but make some small changes. The watch will probably come in two sizes, 41mm and 45mm, just like the Pixel Watch 3. This way, people with different wrist sizes will have options. However, renders show that the Pixel Watch 4 will be a little thicker at 14.3 mm than the 12.3 mm of the previous model. This thicker design is probably meant to fit a bigger battery or more parts, which is one of the most common complaints about older models: battery life.
People are saying that one of the biggest design improvements for the Pixel Watch 4 will be that it will be easier to fix. iFixit gave the previous Pixel Watch models a low score of 4 out of 10 because they were hard to fix and had a sealed, non-repairable design. Google’s answer to a cracked screen or broken part was to replace the whole device, which was expensive for users and bad for the environment. Android Headlines says that the Pixel Watch 4 will have a new internal design that makes it easier to take apart and replace parts. This is a big step forward for sustainability. This change is in line with Google’s bigger environmental goals, like recycling programs and goals to be carbon neutral.
Another interesting rumor about design is that wireless charging might come back. The first Pixel Watch could be charged wirelessly, but the Pixel Watch 2 and 3 couldn’t because they used pogo pin chargers that only worked with their own devices. Leaked images of the Pixel Watch 4 show that it doesn’t have these charging pins, which suggests that it will go back to inductive charging. This would make things easier and work better with third-party chargers, putting Google on the same level as Apple and Samsung. There are also rumors that the watch can charge from the side, which would let it work as a bedside clock when docked.
The Pixel Watch 4 should still be water-resistant (up to 5 ATM/50 meters) and have scratch-resistant glass, but it doesn’t have the sapphire glass that competitors like the Apple Watch and Samsung Galaxy Watch use. The colors will include Black with an Obsidian band, Moonstone (gray) with a matching band, Gold with a Lemon band, and Silver with either Iris (purple) or Porcelain (beige) bands. A new Gradient Stretch Band and other accessory choices will let you personalize your watch even more. This is in line with Google’s goal of allowing users to personalize their watches with interchangeable bands and customizable watch faces.
One of the most surprising things about the Pixel Watch 4 is that it still uses the Snapdragon W5 Gen 1 chipset, which is also in the Pixel Watch 2 and 3. Some people thought Google would switch to a newer Snapdragon Wear chip or the rumored Tensor wearable chip made by Google. However, Android Authority says that Google will stick with the W5 Gen 1 for 2025. A custom Tensor chip might come with the Pixel Watch 5 in 2026. To make up for this, Google is adding a new M55 co-processor to the W5 Gen 1. This will improve AI performance by up to five times while using less power. This could make it easier for the watch to handle AI-driven features like Gemini commands.
Since the first Pixel Watch didn’t do well, Google has been focusing on battery life. The Pixel Watch 4 is expected to have bigger batteries: the 41mm model will have 327mAh (up from 307mAh, a 7% increase) and the 45mm model will have 459mAh (up from 420mAh, a 9% increase). With the always-on display (AoD) turned on, the 41mm model is said to last up to 30 hours and the 45mm model is said to last up to 40 hours. This is thanks to the new features, the M55 co-processor that saves power, and the Wear OS 6 improvements. It’s also expected that charging will be faster, but the exact speeds are still a secret. These changes are meant to make the Pixel Watch more competitive with watches like the Apple Watch Ultra 2 and the Samsung Galaxy Watch Ultra, which have batteries that last for days.
The display is another area that has been improved. The Pixel Watch 4 is expected to have an LTPO AMOLED screen that can get as bright as 3,000 nits, which is more than the 2,000 nits that the Pixel Watch 3 had. This should make it easier to see in bright sunlight, which is a common problem when using it outside. Also, leaks point to bezels that are a little thinner, which would make the viewing experience more immersive and stylish.
Wear OS 6 will come with the Pixel Watch 4. Google has already said that it will have new features like Gemini AI integration, a Material 3 Expressive UI, and new watch faces. Wear OS 6 is made to use less power, which helps the battery last longer. Google Maps, Google Assistant, Google Wallet, and the Play Store all work together very well, which is still a big selling point for Android users. The watch will still work with Fitbit’s health and fitness tracking, and it comes with six months of Fitbit Premium.
The “Breathing Emergencies” alert, which uses continuous SpO2 (blood oxygen saturation) monitoring to find low oxygen levels and warn users of possible breathing problems, is said to be a standout feature of the Pixel Watch 4. This adds to the Pixel Watch 3’s “loss of pulse” detection and works with other safety features like Emergency SOS, car crash detection, and fall detection. Emergency satellite communication is another feature that could change the game. It would let the watch connect in places where there is no cellular coverage. This could give Google an edge over Apple in the smartwatch market. But how well this feature works may depend on where you are and what carrier you use.
There are also rumors of a touch-sensitive bezel that would let you use gestures like swipes and squeezes to control the device. This could work with the crown and side button that are already there. There are two new buttons near the speaker that were leaked, and they seem to add more functionality, but it’s not clear what they do. The watch is also expected to have ECG, heart rate monitoring, and ultra-wideband (UWB) for accurate location tracking. This will improve features like finding devices and digital car keys.
Google bought Fitbit in 2021 and added its health-tracking features to the Pixel Watch line. The Pixel Watch 4 is expected to improve these features even more. Leaked information suggests that the new sensor array could make tracking heart rate, sleep, and activity more accurate. The “Breathing Emergencies” feature shows how much Google cares about health monitoring. This could make the Pixel Watch 4 a great tool for people who have breathing problems. People liked the Pixel Watch 3’s running tracking, but Google will probably listen to what users want and improve other fitness metrics, like counting steps and tracking calories, so it can compete with dedicated fitness trackers like Garmin.
The Pixel Watch 4 should keep the same prices as the Pixel Watch 3. The 41mm Wi-Fi model will start at $349, and the 45mm or LTE models will start at $399. The Made by Google event on August 20, 2025, in New York is expected to be the place where the Pixel Watch 4, Pixel 10 series, Pixel Buds 2a, and a new Pixel Stand charger will all be released. There may also be a new feature called “Pixelsnap,” which is Google’s version of MagSafe. This would make charging more compatible across all of Google’s products.
Apple and Samsung are the two biggest players in the market for smartwatches, but Garmin, Suunto, and smaller companies like Mobvoi also compete. The Pixel Watch 3 was praised for its software and design, but it didn’t last as long or work as well as competitors like the Apple Watch Ultra 2 and Samsung Galaxy Watch Ultra. The rumored improvements to the battery and repairability are good news, but some people want a Pixel Watch 4 Ultra—a tough, high-performance model that can compete with high-end fitness wearables. A device like this could keep the Pixel Watch’s famous design while adding features that make it more durable, like sapphire glass or a titanium frame.
The Google Pixel Watch 4 looks like it will be an evolutionary upgrade, building on the best parts of its predecessors and fixing the worst parts. It promises to be a more useful and long-lasting smartwatch because it has a slightly thicker design, bigger batteries, a brighter display, and is easier to fix. Wear OS 6, advanced health features like “Breathing Emergencies,” and the possibility of connecting to satellites could make it a great choice for Android users. It’s disappointing that they chose to stick with the Snapdragon W5 Gen 1, but the new M55 co-processor and software improvements should make sure that it runs smoothly. Google is getting ready to show off the Pixel Watch 4 on August 20, 2025. It’s clear that the company is serious about its wearable goals and wants to catch up with the best in the business while still sticking to its vision of an AI-driven ecosystem.
