The most notable thing about the GoPro Hero 11 Mini is its lack of a large, rear display. The camera is controlled entirely using the power and record buttons, as well as voice control. Instead of a screen, the Hero 11 Mini features a large heat sink on its rear, as well as a second mounting bracket.

My only major complaint with the GoPro Hero 11 Mini is that it doesnt feature a removable battery. I fully understand why this decision was made, as a replaceable battery would no doubt have meant increasing the size of the Hero 11 Mini. However, it does limit the life span of the camera, and if something goes wrong with the battery, then the entire device is toast.

    You shouldnt wait until the batteries run out of power completely before you change them with new ones. You will get a warning about low battery power if you have a thermostat with an LED screen. The low battery warning will come on, usually saying either BATT LO or Replace Battery.

    If you do see this warning, its best if you just change the batteries right off. If not, then your next warning is a blank screen. If you still dont replace the batteries, eventually your thermostat stops working altogether.

    Maybe youre not all that worried about changing the batteries too quickly because your thermostat only uses the batteries for backup. However, youll still have problems. While most of the other programmable functions will continue working, the low battery power can cause you to lose your date and time settings. That can be rather annoying.

    Gopro Hero 11 Mini Price And Availability

    As with other GoPro cameras, the price of the Hero 11 Mini is highly dependent on whether or not you opt to buy into the GoPro subscription service. Its available now, with an MSRP of $450. However, with a subscription, that price comes down to a much more reasonable $300. The subscription costs $50 per year, bringing the total cost of the Hero 11 Mini down to $350.

    That works out to $100 less than the Hero 11 Black, which, given its many similar capabilities, makes the Mini something of a bargain. The Mini is roughly the same price as the DJI Action 2, which is even smaller, though it lacks many of the capabilities of the Hero 11 Mini. The Insta360 Go 2 is another tiny action camera. Its smaller, and it costs less than either the GoPro or the DJI, but it is severely limited compared to either.
