Review on Amazfit Bip U Smart Watch Fitness Tracker with 60+ Sports Modes, 9-Day Battery Life, Blood Oxygen Monitor, and Water Resistance for Men and Women - Compatible with iPhone and Android Phones (Black) by Hayden Iskandar ᠌

Overall, I'm really pleased; the negatives aren't as severe as I thought, and the positives seem to well exceed the negatives. Except for the annoying vibration, of course. When faced with a choice between MiBand 6 and Bip U, I opted for the latter and have no regrets. features advantages: High accuracy in counting steps (I'll get to the downside in the cons section) Little margin for error in counting pulses (one to two percent) (compared with a tonometer and sports chest equipment) Music management in training mode +A single, programmable physical button (long press) + Daytime SpO2 counts are inaccurate, but nighttime readings suggest that a previously problematic breathing pattern while sleeping has resolved itself (BETA mode as of this writing, 05202222). (As of this writing (05202222), the mode is still in BETA status.) Only a few apps have permission to send out notifications. Plus: the Zepp app (which, in my opinion, is far more user-friendly and convenient than the MiFit app); plus: the ability to mute or drop incoming calls; plus: the ability to set an alarm without opening an app. Do not disturb modes that are timed and can be toggled off with a flick of the wrist (so that they don't turn on at night and so that they don't further drain the battery with notifications on the screen) are becoming increasingly common. To-do lists, clocks, and stopwatches are also included (for the female population there is a cycle counting function) +2 pre-made dials with limited customization options; +2 more dials available via download (even suit dials can be downloaded, though with a different program and it seems only on Android) Several drawbacks are listed below: -At full capacity (heart rate every 30 minutes, stress level, sleep control, and SpO2), the battery only lasts around 7-8 days, which seems incredibly short compared to the 30-35 days that my last Mi Band 4 lasted. The vibration from the alarm clock is weak even when turned up to maximum. (MiBand is having the same problem, but Honor produces high-quality vibration watches and bracelets.) -There may be instances where it is unable to compute Stress or SpO2 that is manually measured. -A step counter (possibly without calibration in this manner, but for a considerable amount of time, if a leg or arm suddenly itches, scratching while also walking is not a good idea). Notifications of the same Vkontakte if you wrote 2 dialogues require you to either access the phone or the notification curtain with the clock, as it immediately begins writing 3 unread dialogues in the WhatsApp upon receipt of a new one; however, I am unsure if this is a function of the programs or the firmware of the watch. If you have two active conversations in Vkontakte, for instance, you will be prompted to either check your phone or your notification shade, but I don't think the latter is very bothersome. When I pull out the notification curtain, open the top settings curtain, or just flip the screen, it doesn't always register my actions correctly (maybe it's just me).
