The T8ultra<\/sub> is a 7mm thin 40mm watch, that seems to be the true compact 2025 successor of the T8classic<\/sub><\/a> originally from 2022
\n\"\"<\/a><\/p>\n

<\/p>\n

Forget about the T8 trio<\/a> from the spring of 2024!<\/p>\n

The T8ultra<\/sub> has an exterior much like the T8mini<\/sub>, BUT does NOT share its interior, and got the calling capabilities of the T8pro<\/sub> in a more compact body (both part of the above mentioned 2024 trio).<\/p>\n

Luckily they are back with their own QWatchPro<\/strong>, and not the crappy DaFit app.<\/p>\n

I have a very positive review of it predecessor\u00a0T8classic<\/sub><\/a> so you might want to glance at that too. (I was less happy with the 2024 T8 Trio, reviewed here<\/a>)<\/p>\n

(*) The T8orig<\/sub> with 1.00_24<\/strong> is 12% heavier than the 1.00_23<\/strong> in exactly the same case dimensions, Perhaps larger battery??)<\/span><\/p>\n

The T8Ultra<\/sub> is offered in ‘Gold’ and ‘Black’ (that really is more like ‘gunmetal’)<\/p>\n

Though the case of the T8Ultra<\/sub> (right) looks a lot like the T8mini<\/sub> (to the left) at first glance it is slightly thicker, and the slanted region of the back a bit less, so larger volume<\/p>\n

\"\"<\/a><\/p>\n

Personaly I find the 18mm band they use a bit disproportional. Less half the width of the watch just looks odd in my book.<\/p>\n

 <\/p>\n

Bezels<\/h2>\n

The T8ultra<\/sub> has quite large bezels, especially if you compare it to the U17<\/a> I got one day earlier…<\/p>\n

If you just pick a random colourful watch-face it can look really bad<\/p>\n

\"\"<\/a><\/p>\n

Or just one with a bright edge, that really makes the bezels scream out:<\/p>\n

\"\"<\/a><\/p>\n

But if you pick it carefully, and use something that has a black background or fades towards black, it is OK (see below on the APP for the many options)<\/p>\n

\"\"<\/a><\/p>\n

And here with the H06<\/a> squeezed in as a watch with bezels between the two, that all have roughly the same case area (ignoring the band-arms of the T8Ultra<\/sub> and H06)<\/p>\n

\"\"<\/a><\/p>\n

 <\/p>\n

App<\/h2>\n

I’m really glad to see it being back on QWatchPro, that was used by the T8classic<\/sub>, a much<\/strong> more stable app than DaFit used for the 2024 T8-trio.<\/p>\n

The T8ultra<\/sub>\u00a0 got 5 fixed watch-face, got one with your own background and is offered 472 watch-faces for free download, but you can only store one<\/strong><\/span> on the watch at the time \ud83d\ude44 (and currently no way to mark the ones you like as favourites, so a bit complex with a LOT of swiping to change)
\n\"\"<\/a> \"\"<\/a> \"\"<\/a> \"\"<\/a><\/p>\n

For more on the QWatchPro also look at the the very long review of the T8Classic<\/sub><\/a> I used for years.<\/p>\n

 <\/p>\n

Sleep<\/h2>\n

It’s included in a small sleep-test I did here<\/a> (as the winner).<\/p>\n

 <\/p>\n

Battery and charging<\/h2>\n

AOD turned ON<\/h3>\n

Removed from charger at 100% 2025-09-26 22:45, AOD turned ON.
\nThis is the AOD-on face
\n\"\"<\/a>
\nAfter 23\u00bdh it was at 61%, it died somewhere between 1:40 and 2 the next night, so 51h with AOD ON<\/strong>, and this is totally acceptable in 2025 for such a small and thin watch.<\/p>\n

AOD turned OFF<\/h3>\n

Unplugged recharged fully 2025-09-29 19:00. After 14 days it was at 44%, But it dived deep in the low end and after 16d 8h it was at 2% so 2\u2153 weeks<\/strong>.<\/p>\n

 <\/p>\n

Conclusive remarks.<\/h2>\n

I’m not really at a full conclusion, though the large bezels and the coarse HR monitoring is a disappointment, the rest seems fine. But I did give up on it for that after the discharge test. Despite the very good results in the sleep test.
\nOne thing I love on the T8Ultra<\/sub> (that I really<\/strong> miss on the H06) is the simple feature of pressing the button an extra time to turn off the display rather than waiting for a timeout. A simple double-click and you got the time and is back off… super simple tiny detail, but daily miss it on almost all others I tested.<\/p>\n

This will not be a new daily driver though, I’ll stick with the just 1.3% thicker and 2.5% wider H06<\/a> with its 23% larger screen and less coarse monitoring.<\/p>\n","protected":false},"excerpt":{"rendered":"
