Best Cell Phones - ~Quad.* Processor Type, 7 to 12 Hours Talk Time

'A compact phone indeed.'

'While I may not be entirely sold on the design changes, using the Z5 Compact has been great. '

'Long lasting battery.'

'The processor inside is a Qualcomm Snapdragon 810 which is a nice upgrade from the Z3 Compact which has a Snapdragon 801.'

'Competitive specs.'

'The display can be sufficiently bright and we found that things were relatively sharp.'

'Running a mostly stock Android Lollipop experience. '

'Fast processor.'

'Fast performance.'

'It’s disappointing that Sony hasn’t matched the Z3’s Full HD display, but this is still good for a phone this size, and it matches what the competition currently offers.'

'The Sony Xperia Z3 Compact packs a larger screen than its predecessor in the same size body, it has tonnes of power, it's completely waterproof allowing for underwater photography and it has a good camera.'

'fairly sharp picture'

'From the minimalist look in front to the textured 'moonstone grey' back panel, the phone is still attractive and feels great to hold. '

'It’s a nice phone, but the only thing that stands out at present is a totally unacceptable overheating problem with the camera. '

'A rectangular two-sided glass slab held together by a metal frame makes for a premium styling which feels equally nice to look at and handle.'

'With decent hardware and a price tag of around ?300, it is a solid phone. '

'It will feel comfortable to most users and the Xperia M4 Aqua is very thin and light for a mid-range phone at 7.3 mm and 136 g.'

'We were eager to see how Qualcomm's new CPU performs, and the results were quite positive.'

'The viewing angles are wide too.'

'Despite being a large 5.5-incher, the Yu Yureka is slender and lightweight. '
