Hi there, The phone I have now, a BLU life one x 2016, is slowly dying (battery drains really fast). On top of that, it's been a while now I felt I need a bigger screen as I'm using the phone more and more for work (pdf, documents, notes...) and my eyes start feeling tired. After the experience with the BLU life one x, which hasn't been bad or great, just OK, I'm considering at this point to get something better. I think what I would like to see in my next phone are more performance and bigger screen. That said, I'm looking at two models in particular: Sony Xperia XA Ultra and Huawei Mate 9. I can find the former for about $260, which budget wise is really good, whereas the latter runs about $450. The Sony comes with a 6" screen and the Huawei with a 5.9" screen. I don't know the two phones at all, I have only read some reviews and I guess they are good phones. So, what I'd like to ask you is: Are the Sony and the Huawei worth their price? Is it the Huawei significantly better to justify the extra cost? (By this I mean, more performance, a better battery which possibly lasts longer?) Is there any better or equivalent alternative for the same price range which I should take into account? Thanks for any help or info!
