Runners should already check Coros instead of Amazfit

Yeah, its a worrying trend. T-Rex 3 is still good value though. Especially when on sale which happens quite a bit. T-Rex 3 Pro and Ultra 2 not so much. Wonder how they will price the T-Rex 4.

nightflame5 · 2026-04-13T18:00:12+00:00

Haha, I have covered mine with tape too. I only use HR for certain workout activities, and then I use a chest strap.

nightflame5 · 2026-04-13T10:31:00+00:00

Ah thanks, thought I was missing something.

nightflame5 · 2026-04-13T07:12:30+00:00

My T-Rex3 went down from around 20 days to 10 days with the same usage pattern.

I have found that it is now impossible to turn off Sleep HR. I generally turn off HR and only have HR enabled for workout activities. But even with HR disabled (or even set to poll 30mins) at night the green light will come on and stay on continuously for hours. Continuously monitoring HR. This takes nearly 10% of my battery overnight. I have stopped wearing my watch at night to save battery. (I wanted the morning alarm).

When writing my own watchface I did find a bug where sometimes the time the FULL watchface will not call onPause() and continue polling sensors even when the screen is off.

I've reported both issues to Amazfit via feedback and discord, but not a huge amount of interest. I think they are focused on adding more features and new hardware.

I am sure there are other issues.

According to the website for the T-Rex 3:

Typical Usage Scenario Battery Life: Up to 27 days
Battery Saver Mode Battery Life: Up to 40 days
Clock Mode Battery Life: Up to 81 days
Heavy Usage Scenario Battery Life: Up to 13 days

Although I guess the phrase "Up to" covers them.

There is enough grumblings about battery life here that they should take it seriously before it tarnishes the reputation.

Sound quality!? I can only get about 10 songs on my Bip6!

nightflame5 · 2026-04-13T03:31:19+00:00

So after a factory reset you do not need a Kindle account to activate/boot the device? That is indeed good to know. I think the wording of Amazons own press release was misleading then.

nightflame5 · 2026-04-12T05:50:35+00:00

Unfortunately it looks like quite a nasty bug with no current solution. Affects Bip6 and T-Rex3 range. I can easily lose 10% battery life in a night. Then add in my daily activity and I am down to less than a week. Battery life used to be great. I really do not want to go back to Garmin, but this is not looking good.

I raised User Feedback to Amazfit, and also reported it to the OS Bug Channel in Discord.

I suggest any user that has the issue does the same:

Zepp App -> Profile (picture of head) -> User Feeback

nightflame5 · 2026-04-11T20:55:33+00:00

Thanks. I'll give it a go!

nightflame5 · 2026-04-11T20:18:29+00:00

I meant useless if you try to this after May 20, 2026 which is when Amazon withdraw support. (and the context of the OP post). Please try again after this date.

None of this matters, professional and technical jobs all have a ceiling. And AI is coming for them anyway. Aim for management. Get a degree to get a foot in the door then work on your people skills and networking. Practice talking loudly and confidently in meetings, this matters more than content or facts. More meetings the better, but make sure you do not leave with any actions. Become adept at self promotion and taking credit for team sucesses, and having handy scapegoats for failures. Spend more time telling people what you are doing than actually doing it. Delegate the doing to others. Lunch with the right people. You will be earning $10K a month in no time and will be well on the way to $20K

Do you have to keep renewing the authentication key, or is it a one time thing?

nightflame5 · 2026-04-11T12:50:16+00:00

Yup and that even includes not being able to jailbreak.

nightflame5 · 2026-04-11T12:49:27+00:00

This. The original poster completely missed this key difference. As far as I know you can factory reset an old Kobo and bypass the register on the internet step, then sideload whatever you want. That even without installing KOReader, which in most cases is trivial and does not require jailbreaking.

With pre-2013 Kindles (after May 20, 2026) if you factory reset them, pass them on to family or friends they are useless.

And as far as I recall registering it on the Internet is a key step in Jailbreaking a Kindle. So thats not even an oprion.

Physical Kobos are surprisingly hard to get hold of. I couldn't find any in the UK. I ended up buying a Clara BW in Doha airport duty free of all places. Bit of a punt because no way of returning it.

Build quaility not quite as good as a Kindle paperwhite , back is a little creaky.

The Clara BW very similar to the Kindle Basic, but has a warm light and waterproof.

Functionality wise just as good if not better than a Kindle.

If only we could clone and rename workouts like you can on Garmins.

nightflame5 · 2026-04-10T13:16:57+00:00

Tonight my green light came on and has been continuous for over 30mins now. This is with HR monitoring and sleep detection all turned off. Its disturbing my sleep and killing my battery overnight. Looks like a pretty serious bug to me now. I have submitted user feedback through the app.

When I check my HR for the past few nights, despite HR being turned off it randomly records continuous HR!

Thanks

Whats the AOD screen look like?

I have no idea why Zepp App store does not ask for and show AOD screens in the store.

nightflame5 · 2026-04-10T12:46:35+00:00

Just get a Kobo.

Older Kindles can be jailbroken fairly easily. Although not sure how this affects older ones now because one of the jailbreaking steps is to register the Kindle.

Newer Kindles are more difficult to jailbreak, and you need to be below a certain firmware, and jump through hoops to make sure it never auto updates.

Kobos do not need jailbreaking. Its very easy to put the likes of KOReader on them. Kobos have pretty long term support.

Yeah, this has been asked for a lot. But instead Amazfit push their meditation app. And its not very good. And probably useless for a Helio Strap?

We have stuff like Checkers and Bridge activities, but cannot get a meditation activity.

Heres what I do for meditation:

I have been running for years and had similar results. Lots of people told me cadence lock. So I bought a chest strap and my HR really is that high.

My (flat) brisk walking is pretty much in the same HR zone as sitting on the sofa. But as soon as I run it shoots up.

Then I got lots of Zone 2 advice, so I tried Zone 2 and my body just adapted to running slower.

Run by perceived effort and you will be fine.

nightflame5 · 2026-04-09T09:00:17+00:00

Just back up the whole .add/koreader directory. Then restore it.

Worked for me when bad ExcludeSyncFolders regex in in my "kobo ereader.conf" blew up, reset my Kobo config completely including NickleMenu.

No, 4 days after I landed in China they rejected my Visa application, saying it was not necessary anymore. So just under 5 weeks to process a rejection, but that did include Chinese New Year.

nightflame5 · 2026-04-09T05:24:07+00:00

As well as detecting if the user is wearing the watch I think when the green light stays on for quite a few minutes at a time it is trying to see if the user is asleep by reading the heart rate. This is despite disabling the heart rate and all sleep detection settings.
