huami Amazfit Bip U Smartwatch

The packaging used by Amazon was really good.Coming to the packaging of the watch itself, wow, the unboxing experience was comparable to that of APPLE products, really clean.And coming to the sensors, it has Heart rate and SpO2 sensors along with a 6 axis accelerometer.1. The Heart rate sensor works fines with a margin of error of 2-3 beats per min.2. The SpO2 sensor is not a gimmick, it works fine but not 100% accurate, it was of by nearly 2% every time.** Both the sensors do no work if the watch is not on your hand**So both are just not for namesake and are functional.**It doesn’t have GPS built-in the only CON at this price.**The display is pretty good and gets adequately bright.Coming to the battery charging time, it takes around 1.5hrs for 30-100%.***Update 1: The battery only lasts for 6 days, when HR set for continuous for every 10min, sleep tracking on and also notifications on for sedentary and calls and exercise tracking for 30 min a day.Checking SpO2 10 times a day manually and always on for stress measurement.Lifting the watch up to light the screen for nearly 50 times a day.I expected it to last for atleast 7 days though(claimed was 9 days).***UPDATE 2: Using it for nearly 2 weeks now , received a firmware upgrade, and the accuracy of the SpO2 as well as the HR sensor have improved and also the battery life has improved to around 7 days now.****UPDATE-3( 24th Jan 2021): Using it for almost 3 months now, I guess all the hugs ar fixed, most of the measruu are accurate, but the step counter sometimes registers steps even if I don’t walk :P.Battery life on average 7 days with HR every 10 min and stress measurement on and daily once O2 measurement and sleep tracking.The band is pretty comfortable, no skin irritation or discomfort.Received around 6-7 updates till now.This watch is a good budget choice based on my usage for almost 3 months now.

Update after 3 months usage:-Sleep tracker has gone drunk from past few days. As you can see in the photo, I slept at 1:31 in night and woke up at 8:29 in morning (which are correct records, kudos for this) which means I slept for 7 hours but it’s showing just 3:30 hrs. I mean it’s simple maths. Lol.-After disabling all trackings, I’m getting more than 10 days of runtime out of this(screenshot attached). Which is sufficient I guess. With all trackings on, you can get 5-7 days.-It had many small bugs when I purchased it, like spelling errors, not been able to turn off heart tracking, but in the recent software update they fixed aome of them, though the accuracy is same as it was, 70-85%.So yeah they might also fix this sleep tracking bug in the next update.-Also, get a screenguard for this since the screen is not fully scrach-proof.——————————–It’s a good watch but there are a lot of things that could be improved. I’m using this watch for 3 days and this is what I found-Pros–pomodoro timer is effective for any focus work. I use this while reading.-have a lot of exercise modes. Though I don’t really use them.-alarm is effective. Always get me up.-can control songs and camera from this. Good feature.-magnetic charger is good and easy to connectCons–Unable to turn off full day heart rate tracking. It turns on automatically.-a lot of spelling mistakes.-steps counter is about 80-85% accurate.-i tested heart rate while on my exercise bike and it showed only 70-75% accuracy.-charged this watch to 95% on the first day and it have 50% battery on the 3rd day with full usage. So battery could be improved.-when I lift my hand to see the time, it takes about 1 sec for the watch to light up. This can be a little frustrating if you’re in hurry.-i tested it’s spO2 and stress tracker as well but not sure about their accuracy. Though I believe it’ll also be about 70-85% accurate.-sleep tracker is also not intelligent. Like if u went to bed at 11 and used your phone or book for 1 hour and went to sleep at 12 then it’ll count your sleep from 11 and not 12.Though I’m sure some of these cons will be improved by the next software update.So if you want to buy this watch then go for it if your main purpose isn’t heart rate tracking or other tracking and just want a smartwatch for alarm, timer, and other little stuff.
