Huawei Watch GT 6 Pro Review: Two Weeks Between Charges, One Big Catch

Most sports watches ask you to choose between a screen you can actually see and a battery that lasts. Huawei's answer with the Watch GT 6 Pro is to refuse the question: you get a 1.47 inch AMOLED at 466 by 466 pixels, a titanium case, and a battery Huawei rates at up to 21 days. Even the honest, real world number sits somewhere near a fortnight, which makes every mainstream rival look needy.

At roughly £265 it undercuts a Garmin Fenix by hundreds and a Forerunner 970 by a fair chunk too. Its nearest rival on price is really the Garmin 265, which costs a little more and wins comfortably on training analysis. The hardware is genuinely premium. What you trade away is the software ecosystem, and whether that trade works depends almost entirely on which phone is in your pocket.

Who it is for

Buy this if you resent charging things. Runners, cyclists and hikers who want proper metrics without a nightly top-up are the target, and the 40 hour GPS figure means a long weekend in the hills doesn't need a cable. It also suits anyone who wants a serious looking watch: titanium, sapphire style finish, 54.7g without a strap.

Skip it if your training life runs through third party apps and a coach. There's no rich app store here, and while Huawei Health exports to Strava, the wider plumbing that Garmin and Coros users take for granted is thinner. Our best Garmin watch guide covers that side of the market.

Battery life is the whole pitch

Huawei's headline claim is 21 days, which assumes a quiet life: raise-to-wake only, light notifications, a few hours of exercise a week. Their own typical-use figure of 12 days is closer to what most people see, and owner reports cluster around that (Huawei's published UK battery conditions spell out exactly what each number assumes, which is more transparency than most brands bother with).

Switch the always-on display on and the number drops to roughly seven days. That still beats an Apple Watch by a factor of seven. The figure that matters to endurance athletes is 40 hours of continuous outdoor sport mode, enough for a full Bob Graham attempt with charge to spare, or a week of daily hour-long runs without thinking about it.

Screen, build and what titanium buys you

The AMOLED is the second reason to want this watch. At 1.47 inches it gives you more usable data fields mid-run than a 43mm Forerunner, and in September sunshine it stays readable without squinting. The titanium case keeps the weight at 54.7g, light enough that sleep tracking doesn't feel like wearing a cricket ball to bed.

Durability goes further than the usual 5 ATM box-tick. IP69 means it shrugs off high pressure jets, and the depth sensor supports freediving to 40 metres with apnea training modes. Very few people will use that. It's still a sign that the hardware wasn't built down to a price.

Training, maps and cycling power

For running, you get ground contact time balance, vertical oscillation, trail metrics with altitude trends, and waypoint navigation. Offline maps download free through the Health app, which matters if you run somewhere with no signal; Garmin charges nothing for this either, but plenty of watches at £265 simply don't offer it.

Cycling is where Huawei has pushed hardest. The watch estimates virtual power from speed, gradient and your rider profile, and tracks real time cadence with no sensors on the bike. It isn't a replacement for a crank-based meter, and anyone training to precise zones should still buy one and pair it, because the watch will happily record real power and track FTP when you do. As a rough guide for a rider who has never seen power numbers before, it's genuinely useful, and our best turbo trainer guide covers the indoor side of that setup.

Golfers get 17,000 plus course maps worldwide, over 3,000 in the UK, with zoomable greens and yardage.

Heart rate, ECG and the accuracy question

The optical sensor is good for steady efforts and everyday tracking, and it does the usual wrist sensor thing on intervals: a few seconds of lag at the start of a hard rep, and the occasional lock onto cadence. This isn't a Huawei failing so much as physics. Reviews of how these devices get validated have criticised the field for testing under conditions that flatter the hardware, so treat any brand's accuracy claim with scepticism (methodological shortcomings of wrist-worn heart rate monitor validations). If you train by heart rate zones, add a strap. Our heart rate monitor guide covers the chest options worth having.

The ECG feature works from the watch: hold the electrode for 30 seconds and you get a report on the screen. Useful as a screening prompt, not a diagnosis.

The software catch

Here is the part reviews tend to bury. Huawei Health isn't in the Google Play Store, a consequence of the US trade restrictions rather than any technical problem, so Android owners download it from AppGallery or Huawei's site and approve an install from an unknown source. It takes five minutes and it works. It also makes some people uncomfortable, and that's a fair reaction.

On iPhone, the watch pairs and tracks properly, but you can't reply to messages from the wrist. Notifications are read-only. For a lot of buyers that alone settles it.

Third party app support is the other gap. There's no meaningful equivalent to Garmin Connect IQ, so what ships is what you get. Data syncs out to Strava, and if that's your whole ecosystem you'll never notice the limitation.
