I think the previous model had the best battery life of any phone GSMArena had tested, so I guess that’s the niche. But I’m sceptical of a crossover between people who buy phones with with an extreme focus on battery life and people who buy phones with pretty unimpressive and out of date mid-range processors. Particularly at the price the 10 series retails for. I’m struggling to understand why Sony continues with the 10 but I guess there is a market somewhere.
