Pixel Watch 5 vs 4: Leaked specs point to a costly small upgrade

A major Pixel Watch 5 leak has filled in nearly every blank, and the result is a watch that does not change very much. Google appears to be adding a tweaked Snapdragon chip, 3GB of RAM, 64GB of storage, slightly larger batteries and a new HNBR band, while leaving the design, display and quoted battery life pretty much untouched.

The latest information comes from a full specification sheet published by Dealabs, along with leaked marketing material. Of course, the Google has not announced the watch yet, so these remain known leaked specifications rather than confirmed final details.

Pixel Watch 5 is expected to debut at Google’s August 12 event, with earlier information pointing to pre-orders on August 13 and a retail release on August 20. We previously covered the expected Pixel Watch 5 release date and pricing, but the new material gives us a much clearer idea of what buyers will get for their money.

The hardware story is small but not empty

The processor is not quite the straight carry-over it first appeared to be. The new specification sheet names it as the Snapdragon W5 Gen 2 Accelerated, paired with a Cortex-M55 coprocessor.

Qualcomm has not announced a chip under that name, so the word “Accelerated” is doing a fair amount of work here. An earlier Google Play Console listing showed the same SW5100 platform, four Cortex-A53 cores running at 1.7GHz and Adreno 702 graphics at 1GHz.

That suggests Google may be using a tuned or revised version of the existing platform rather than a different chip architecture. It could still bring better performance, but there is not enough information yet to say how much faster it will be.

The more straightforward upgrades are RAM and storage. Pixel Watch 5 reportedly moves from 2GB to 3GB of RAM, while storage doubles from 32GB to 64GB.

The extra RAM could prove more useful than the storage increase. It should give Wear OS 7 and Gemini Intelligence more room to operate, particularly when the watch is handling workouts, music and background health tracking at the same time.

Battery capacity also rises slightly. The 41mm model moves from 325mAh to 332mAh, while the 45mm version increases from 455mAh to 465mAh.

Despite those larger cells, Google still quotes 30 hours with the always-on display enabled for the smaller watch and 40 hours for the larger model. Battery Saver remains rated at 48 and 72 hours respectively, so this does not look like a meaningful endurance upgrade.

There is another hardware change hiding in the box. Pixel Watch 5 comes with a second-generation Sport Band made from HNBR, replacing the fluoroelastomer Active Band supplied with Pixel Watch 4.

HNBR is commonly used where resistance to heat, oils, sweat and ageing is important. That sounds sensible for a watch band, although we will need to handle it before knowing whether it feels softer, stiffer or more comfortable.

Most of the remaining hardware stays familiar. Pixel Watch 5 retains the 41mm and 45mm sizes, the 3,000-nit Actua 360 LTPO AMOLED display, 5 ATM and IP68 protection, Bluetooth 6.0, Wi-Fi, NFC and UWB.

The physical design also looks virtually unchanged from the Pixel Watch 5 renders that leaked in July. Google is sticking with the domed display, rounded case, digital crown and side-mounted charging contacts introduced with Pixel Watch 4.

Google’s official Pixel Watch 4 specifications confirm just how much has carried over. Watch 4 already includes Bluetooth 6.0, Wi-Fi 6, ultra-wideband, Satellite SOS, dual-frequency GPS and the same health sensor categories.

The Pixel Watch 5 document adds BeiDou and QZSS to the satellite positioning list. That could represent broader navigation support, although it may simply be a more complete description of capabilities that Google did not list on the Watch 4 product page.

Google is selling software

With the hardware barely changing, Google is making software the main Pixel Watch 5 story. Gemini Intelligence is pitched as a proactive assistant that can surface useful information and offer context-aware replies through a feature called Proactive Suggestions.

There are several catches in the small print. It needs a compatible Android phone with Gemini Intelligence, availability varies by country and language, and it is limited to users aged 18 or over. Google also says some features may require a subscription for extended use.

Sleep tracking gets the other big upgrade. Google says it has improved sleep-stage accuracy using an algorithm validated against reference measurements and compared with its latest sleep tracking across compatible Pixel and Fitbit devices. The watch tracks sleep stages and breathing rate, then combines them into a personalised sleep score.

That data feeds into Morning Insights, which brings together wellness indicators, readiness, a detailed sleep summary and the weather. Google says the feature requires the Google Health app, and some information may appear in the app rather than directly on the watch.

Loss of Pulse Detection is also pushed heavily, with Google calling Pixel Watch 5 the only watch that can detect a loss of pulse and automatically call for help. It is not new to this generation, though, as Pixel Watch 4 already supports it in selected markets.

The higher price is the awkward part

The leaked US price starts at $399 for the 41mm Wi-Fi model, rising to $499 with LTE. The 45mm versions are expected to cost $429 and $529.

Pixel Watch 4 launched at $349 and $449 for the smaller Wi-Fi and LTE models. The larger watch started at $399 and $499, so Pixel Watch 5 appears to bring a $50 increase to the 41mm versions and a $30 increase to the 45mm ones. Google’s official Watch 4 launch announcement confirms those previous prices.

That makes the 45mm Pixel Watch 5 look like the better value within the new range. An extra $30 buys the larger display, the 465mAh battery and the longer 40-hour rating, while the gap between the two case sizes shrinks to only $30.

The early reaction on social media has been fairly predictable. Some users see the unchanged design and processor as another small annual refresh, while others say they would rather Google introduce a rugged model or make a meaningful jump in battery life.

That is probably the fairest way to frame Pixel Watch 5 before launch. It may become the better watch once Google explains its software changes, but the known hardware does not give Pixel Watch 4 owners an obvious reason to move.
