    Watch keeps disconnecting from the phone. I’ve hard/factory reset the watch 3 times already.
    The watch itself is a cool looking watch with a great screen and cool watch faces.
    Very disappointed in the issues I’m having.

    1.0 out of 5 stars **UPDATE on the battery life** BAD BATTERY LIFE
    Reviewed in the United States on May 12, 2021
    UPDATE: May 26th 2021,
    Got my replacement T Rex Pro yesterday evening (05.25.2021)
    Fully charged it by 8pm, it’s 3:42pm the next day (05.26.201) I’ve lost 30% in less than 24 hours, the battery life on these suck, I haven’t used GPS or any fitness tracking, just wore it after it was fully charged, wore it to bed, raise to wake off and wore it to work the next day… lost 30%… wack wearable.

    DO NOT BUY IT
    Amazfit doesn’t care and falsely Advertises their battery life. You’ll get 4 days max with little to no use.

    UPDATE: May 21st 2021,
    I scheduled a replacement of this watch, I can’t get more than 4 days max out of the battery, notifications off, vibration off, brightness 1/3 full maybe, I’ve lost 30% in a day and a half, if the second one does the same thing I’m returning it and getting a refund, just poor advertising on Amazfits part, 18 days?! 9 days?! How?! By leaving it home on the table on battery save mode?! Lol this is ridiculous, such a bummer…

    UPDATE: May 15th 2021.
    I reduced my original 5 star review to a 2 star review because of one (in my opinion) major issue. The battery life…

    This watch was delivered to me around 5pm on Tuesday May 11th 2021. I fully charged the watch by 6:30pm (it was completely dead when I got it) after a few days of moderate usage, I’d assume nothing more than normal use I had to charge the watch Friday night, May 14th, I was at 15% and had a lot of outdoor activities planned for Saturday, and at the rate the battery was going I didn’t trust the 15% to last until Saturday night especially while using fitness tracking.
    During the three days after I fully charged it I only used the fitness tracking once, for 1 hour of walking, I’m someone who normally does a lot of activities outdoors like hiking and camping, I don’t want to have to worry about the charge on this during a weekend or longer camping trip, but it looks like I will.
    My always on display was off and the brightness was around 1/3 full, I do have all day heart and stress monitoring on but let’s be real, that’s the point of this device, lift to wake is also on and I have that on the sensitive setting because I don’t want to wait the 3 or 4 seconds for the display to wake to see the time once I raise my arm. I may have checked my SPo2 three or four times, other than that I just wore the watch, all notifications were on but I’m not super popular by any means so it’s not like my watch was constantly going off with alerts. I’m not sure what else I can do at this point to increase the battery life because I feel like turning off features to at least reach the 9 day moderate use projection would be so counter productive to having this device. I feel I may have received a lemon/defective battery, unless I’m missing something.

    Every Review here or on YouTube screams the battery life is so impressive, and to me that was one of the biggest selling points… well, I’m not impressed, I got 2 or 3 times longer battery life from the Amazfit Bip U I previously purchased and I used that thing ALLLLL the time when I first got it, and I didn’t need to do my first charge on that for 7 days… and the battery life only increased with the Bip U as my usage reduced.
    So two stars it is because for the price and the battery life being one of its best selling points I feel it’s extremely misleading.
    Other than that the watch is still amazing, looks and works great.

    Delivered: May 11th 2021,
    I’ve only had the T Rex Pro for a day but I absolutely love it, I’ve been waiting to make this purchase for so long and now that it’s here I’m so pumped.

    Build:
    The watch is light but feels like quality, the band feels really nice and has plenty of room for a wrist of any size, I have really small wrists and I love a chunky watch but it still doesn’t look ridiculous while wearing, I used a tempered glass screen protector so I can’t really make any comments on the watch glass itself but before I put on the screen protector it felt like it would be durable and it definitely resisted finger prints, like the daily ones lol not a greasy chicken wing finger print.
    Over all the build and quality of this watch is super nice. Definitely pleased with that part.

    Functions:
    I mean the stats speak for themselves, between everything the watch and app have to offer this set up will cover just about anything, that’s all I really have to say lol.

    User interface:
    Swiping around feels clean, responsive and all motions looks great, this can be customized for any preference of options to be where you want them. Prioritize the apps where you want to see them first. The buttons are a great addition to navigate the features of this Beaut especially in situations where you can’t use the touch screen. I do wish there were a bit more watch faces to choose from but I’m sure they’ll release more in the near future seeing how this Pro version has only been out since February 2021.

    Battery life:
    The only thing I’ve noticed so far that sucks the life out of this thing is the screen brightness, I lost about 15% battery in the first 5ish hours of wearing this with the auto brightness on, I turned it off and brought the brightness down to just over 1/3 and went a whole day of active use on about 5-8% battery usage. I have just about everything turned on too, but that brightness will take the charge away really quickly. So if wearing your watch shining like the northern star is your thing, (I get it I love a bright watch face) then just expect to probably charge it every 3 ish days.

    Things they could improve:
    I haven’t used this enough yet to really touch on this subject but some simple things that could be added are simple replies to text messages for one, that would be great.
    Some type of voice control or talk to text option would also be great, and possibly having Alexa assist like they have on some of amazfits lesser expensive models like the Bip U pro, seems weird it’s not available on the T Tex Pro.

    This thing is just amazing, I couldn’t be more pleased with this watch/fitness tracker.
    If you’re like me and have been circling this watch on here and YouTube all I have to say is just buy it, you’ll thank yourself later.

    5.0 out of 5 stars Good Looking, Capable Watch, Built to Last
    Reviewed in the United States on July 20, 2021
    First, why I purchased the T-Rex Pro has everything to do with the two digital watches I had before I purchased the T-Rex Pro. Bear with me. More details about the watch itself below that.

    HUAWEI GT 2E

    My 1-year old HUAWEI GT 2E watch strap broke and fell into a trash dumpster, which I didn't notice until it was too late. The $130 Huawei digital watch needed $4 screen protectors which broke almost bi-week, and the watch face eventually scratched up once I stopped replacing the protectors. The lesson here for me was that I wanted something more durable, similar to the Garmin Fenix 3 I had for 5 years prior to this watch.

    GARMIN FENIX 3

    My $650 Garmin Fenix 3 had come with a Saphire un-scratchable watch face. I loved this watch, treated it like a beast until the battery died (which is un-replacable). The memory for my love of the Fenix 3, with the bulky feel, and durable, sporty look, brought me to the T-Rex Pro, which is far less expensive. I was able to purchase the T-Rex Pro with a discount on amazon for $154.

    T-REX PRO

    I've had the T-Rex Pro for several weeks, notably while moving locally and put it through an initiation where I accidentally clanked it against several doorways while walking with jumbo boxes in hands and it came through without a mark, even in one case having white paint stuck to the bezel from a wall where I had to peel off the paint with a utensil from the watch bezel. But no scratches through the 5 day ordeal despite the bezel hitting various doors, etc. The raised bezel no doubt has protected this watch face where the Huwei had failed time and again. As far as I can tell the watch face should hold up well without screen protectors.

    In terms of features, I've seen several reviews incorrectly state that you can only run one app on the watch at a time. They say, for example, if you've started the timer then you can't use the stopwatch, etc. Not true. When you have an app working on the watch just LONG-PRESS the "BACK" button and it will bring you out of the current app and back to the watch face where you can go back into your app list to select another app to use and run while the other one is working. It is possible to use multiple apps at the same time.

    I mostly use the watch for notification for calls, emails, and texts. It does an adequate job for this. I don't need to respond to them but just see what I need to get to while I'm out and about. The pop up notifications to alert you to a new text/email are a little too quick before disappearing for my tastes. When using the Notifications app to read an individual text/email, the messages are again on screen for only a few seconds before automatically kicking back out to the list of texts, so I need to go back and select/open the text again to get whatever part I missed. Also, a word in a text message will sometimes be broken up over two lines. It's not a huge deal in terms of functionality for but I also think it's something that should be fixed as it isn't professional look IMO. I can get past these small issues personally but you should know about them before purchasing this watch all the same.

    I love the look of the watch: the blue color suits me well and I like how the band feels more integrated with the overall look of the watch with the raised texture on the side of the band. In some online video reviews the blue watch color sometimes seemed a little greenish depending on the lighting but in personal it’s more of a matt blue grey which I do like and am pleased with. Please note, I've seen some people say there aren't replacement bands for this watch because they don't use the quick release mechanism on the band. You CAN purchase aftermarket bands for this watch but those bands require two small screw drivers (usually they come with the replacement band) and this was the very same process I used with my Fenix 3. The feel of the watch is good on the wrist and it's not too heavy. My fenix 3 had real heft to it which I kind of liked and wouldn't mind if the T-Rex Pro was even heavier. I imagine though most people would prefer the lighter feel of this watch.

    I downloaded a watch face that reminded me of one I had on the Fenix 3. I used the "AmazFaces" app from the iPhone store for a much wider selection of faces to download. Make sure in the T-Rex Pro "Zepp" watch app to toggle the watch setting for "Discoverable" to "ON" to be able pair and download watch faces from the AmazFaces app.

    The battery is very good. I still won't use an Apple watch because I don't like taking off my watch at night to charge and I like the option of not charging the battery for more than a few days. For instance, I misplaced my charger while moving, so I simply turned off all of the notifications, monitoring and special features, etc and I went 8 days using only 25% of the battery. But, should I turn all monitoring/features on such as heart rate, notifications, watch face always on, etc, I can use well more than 10% in a day. I like being able to adjust and balance what I want to use on the watch and keep a happy medium to battery length.

    All in all, I feel I have everything I wanted with my Fenix 3 at a big discount (sacrificing a little bit of the glitz of having a silver bezel, and the sports app, etc) but still have the pleasant feeling of a rugged watch that will give me a long battery life, take a beating, and provide the features I want.
