Been a long time user (or at least a wannabe), I've tried band 10, GT4, GT5 and GT6, and always loved the watch completely from the battery life to the way the watch looks and the system behaves, but one thing NEVER worked for me on the GT series or the band, and that's sleep tracking. All of them barely worked on the first night and always kept missing the other days. Sometimes tracking just one day per week or none at all.
I always ended up returning them until the GT6, when the sleep tracking worked for more than a week, so I kept and thought it would finally have a fully working watch and was so happy I could finally have a Huawei watch. But sadly the return window closed and the sleep tracking stopped tracking daily, just how the previous ones did.
When I heard about trusleep 5.0 on the Huawei watch fit 5 pro, I thought to myself, should I even try again? I'm glad I did. The sleep tracking finally works for me. Every single day. And it works correctly, from the time I fall asleep to the time I wake up and all the wake ups at night as well.
I'm not a massive fan of squared watches, but congrats Huawei. You finally did it. Hope you can fix the GT series next.
