However, because of its low-resolution display and an efficient processor (Snapdragon 630 Octa-core), it remains one of the top Android phones with the best battery life.

It has a decent main and front-facing camera and offers solid performance. It’s also budget-friendly, a mid-range option compared to other more expensive Sony Xperia phones. However, it’s a bit tight and too big to fit in your pocket. So if you are special in looks and size, then its clutter is a big shortcut.
