Any smartphone, they're not that different and all have the same weaknesses. They're pretty fragile, don't have battery-life and they have lots of bloat and functionality that's gate-kept behind sign ups and cloud accounts
Get yourself a rugged device, made for enterprises. They tend to be a bit more costly, but they aren't fragile, they have great battery-life (although usually low specs to make that work), have no bloat and don't require a sign up or even cloud.
Wow I misread the battery capacity on the unihertz tank and was like when was 2000mAh last a big battery? It's 20 000 mAh. Also there's a Tank2 with only 15 500 mAh.
I have a Fold 5 with a snapdragon 8gen2. I have "light performance mode" on at all times, and deep sleep most apps that I rarely use, and get 8 hours SOT. The 8g2 phones are definitely worth getting for battery life
