Customer Reviews
Liked being compact and rugged, hated being bulky and for the internals!
Hi Unihertz,
The tank mini is so excellent! According to the operation these days, I believe that tank mini is my favorite smartphone. The size and performance are fine to me. The most important thing is the battery life, it has a more life than other smartphone which has bigger size than it. Therefore, I hope you can produce the more product which has same physical size as tank mini. In the other hand, maybe you can try to design tank mini 2 at the same physical size and longer battery life. Tank mini has the same physical size with the mouse is so fantastic!
the best phone i have ever had. this is a very specific phone and not everyone will like it. but for me it is just 10 out of 10. i am very intensively involved in cycling and running and also really love to go to the mountains and go hiking. so my choice fell on compact phones for a very long time. in my arsenal over the past few years there have been various models of Sony Compact, then the iPhone 12 and 13 mini. these are the most convenient phones for using with one hand while running or intensive cycling, period. And then recently I found out about the Tank mini. At first I was quite skeptical about this phone since it was an unknown brand to me before that caused doubts. but still taking a risk I bought this phone and do not regret it one bit, period I have been using it for more than a month and I have something to tell. firstly, the design and ergonomics: the phone fits perfectly in the hand and is made very well. Secondly, performance and battery: the phone copes very well with all everyday tasks, And about the battery, here is a separate Thanks to the developers. The phone may seem very thick to you But in fact, it just fits perfectly and comfortably in your hand. And its battery is more than enough for two or even 3 days of average intensive use. Regarding the cameras, I will say right away, the cameras are the simplest for the budget segment, nothing surprising. But I did not buy this phone for photo capabilities)). A small digression regarding those who say that the screen is very small and inconvenient to use: You are idiots, remember When the iPhone 5 with a diagonal of 4 inches came out, you all ran and shouted "ugh, what a shovel" ..... Clowns 🤣.... here the screen is 4.3 inches and it is quite comfortable to use, I will not say that it is ideal, since typing text on the keyboard is not particularly easy, But to my surprise, I got used to the phone in just a few days. a few more words about the flashlight, It's winter now and it gets dark very early and the sun rises very late, I run a lot in the mornings and in the evenings and this flashlight is just an amazing thing that I use almost every day, which makes it an integral part of this phone. I was also very pleased that Android 13 is installed here, which is more than enough for all my tasks.I wish your company further development and success in prosperity. If you ever decide to release the next model, I will definitely buy it for myself.
How does the NFC feature work or does it work at all?
(My rating is really 4.5/5.0 but I couldn't choose that). I am using the Tank Mini in New Zealand fine with NZ carrier 2degrees, after the carrier's 3G shutdown, meaning 4G 'VoLTE / HD Voice' is working fine for placing and receiving voice calls. The phone seems to be very rugged/robust, great for use in the outdoors. Battery life seem great. Size: it easily fits into a trouser side pocket without you worrying that it's about to fall out. I like the camping light: at medium 650 lumens setting, it's great; it lights up a mountain hut really well when you're cooking in the evening or for those pre-dawn starts.
