P9 lite vs J7 2016 vs M4 aqua

Hello again,

my brother need a new phone because his older nexus 4 died.
So he deciding between these three phones:

- Huawei P9 lite
- Samsung J7 (2016)
- Sony Xperia M4 Aqua

The most important things for him are battery and smoothness...i' believe that all of them have decent camera or?
