Does anyone use one of these, if so what is battery life like on them?

Just looking at the range of Samsung outdoor phones etc.

I had one (b2710). Battery lasts for days. Couldn’t tell you how many, but probably stuck it on the charger once a week, whether it needed it or not. Waterproof, but the screen on mine cracked in my pocket.

Bought them for the plant guys. Seem pretty robust, battery life is good.

I get a week out of mine if I don’t use the internet, but even with heavy usage I’ll get 4 days.

Very tough, properly waterproof, GPS etc etc. Only downside is that it’s a bit bulky…not as bad as a smart phone though.
