In your opinion, what are the best (autonomy, staying power) replacement batteries available (brands, references, vendors) for the different UT phones ?
BQ E5 HD
I think it would be good to gather the information here with, if possible, some internet links.

For MX4, genuine ones (Sony US525569H4, A.K.A. Meizu BT40) for sure.
For Nexus 5 PolarCell.
I've put a lot of work into it, and other than doing the Nexus 5X battery mod, no battery works better.
