[Amazfit] Bo_Doc:
BIP U / POP is available

As I was wondering which one to buy (BIP U or S), I ordered both.

Before I will recieve those two, I want to share unusual data that I was looking for and I have found.

When someone is asking if the watch records abnormal heart rate, you constanlty think about ECG, which is not precisely what people mean.

Of course, medical staff to detect abnormal heart activities will require advanced 24hr ecg monitoring. New watches are offering not so accurate substitution.

Heart beats in constant rate while resting. PPG detects beats and pauses between those beats. To simplify medical terms: when lets say 3 beat-pause cycles have the same lenght, you can be sure there are not any additional beats . When there are 2 normal cycles and suddenly one beat comes much earlier than it should be, then the pause to the next beat is much longer. That's how how it happens. Those changes, unpricesly of course, can be detected by HR detectors.

That was the funtion, that BIP s should already have, as the gearbest states:

High Precision Heart Rate Tracking with Huami Bio Tracker PPG optical sensor provides 24/7continuous heart rate measurement with heart rate interval values

abnormal heart rate

, with 98% improved accuracy compared to previous generations. Bip S also allows to see the hr curve directly from the watch screen.

...but it doesn't, which is awful.

However new BIP U has that option.

BIP U manual, page 12

• Abnormal heartbeat alerts

1. Keep the watch connected to the phone, open the Zepp app, and go to Profile > My Device > Amazfit Bip U > Health Monitoring to turn on Heart health monitoring. Then, the watch monitors your heart health and records heart rate changes all day.

2. The watch vibrates when it detects abnormal heartbeats.

Also:

BIP S wasn't able to change tracks while training after watch premiere. Now it can, which means it's propably software related. BIP S has same bluetooth version as GTS so its hope for GTS update someday.

Still I'm wondering which one to keep when those two will arrive

BIP S:

+longer battery life

+music can be changed during workouts

+smooth menu operation

+basic sport modes

+track changing during workout - it wasn't avaliable during premiere, now it is

*Transflective AoD screen which guarantees low power consumption, not too beautiful but very funtional (this is not pros and cons point - its just how it's made and if you don't like it, then you should look for another watch)

-GPS (which I dont need as I workout with my phone; had to pick this one as only S with GPS supports swimming wtf)

-no abnormal heart rate detection

-no camera control

-no SpO2

BIP U:

+Pretty screen, colorful watchfaces

+abnormal heart rate detection

+no GPS

+more productivity and training reminders

+camera control

*music can be changed druing workouts? status unknown

*SpO2 (but REALLY LOW ACCURACY!)

-no AoD

-60+ useless sport kinds, workout menu too complicated

--screen not so smooth, screen misunderstands touches - if touch is not applied accurately, it can swipe to next screen, load it partialy (1/2 screen, most of cases top part) and then jump back to home screen - looks pretty bad

-useless wechat, nudge, to-do-zepp-related notifs implemented

-bip-unlike battery life, ~6 days

Those are only my opinions.

I also have a couple of questions, not so noobish I guess:

Can watch and wireless headphones be connected to phone at the same time? Can you control music by watch in this situation?

Does BIP s with GPS disabled at all times consume more battery than BIP S lite without GPS?

Can BIP s screen be turned off completly, and light during wrist wake-up move?

Does any watch manufactured by amazfit or xiaomi have analog watchface with second hand moving completly smooth, not jumping once a second?

Thanks in advance!
