An Android rival for iPhone 5s?

Question

Are there any good small android smartphones? I've been using LG G2 Mini for almost two years now, and it has always seemed too big for me (neither am I happy with its performance).

To be honest, what I'm looking for is a phone that:

1. is small (given the current trend, the smaller the better)

2. has Android

3. works well with Pokemon Go (good performance and battery). :D

I've used a little bit of iPhone 5s and it's just what I want, but Apple OS slightly plays on my nerves. Is there any Android phone that can compete with it over size, performance and battery?

A decent size of internal memory is also welcomed. My old LG G2 Mini got completely stuck even though I moved literally everything I could to the SD card.

Answer 1

So, this isn't the smallest 4" phone, but I was amazed to find a phone like this, so I'm going to put it out here because I wasn't aware these kinds of phones existed - I recommend the Sonim XP7. This phone is kind of a monster. It's a little short on the internal memory at 16gb with no way to add more, so that is a concern, but... this thing has a 40h talk time. That's crazy. It's also very well reviewed for its GPS performance. The CPU and RAM match or beat the 5s. But yeah, it is a little bigger, and yeah, it doesn't really match up in terms of storage capacity. Still, you can find it on the used market for pretty darn cheap. Here's a comparison across all the considered devices.
