Please run again battery tests for Lumias 950, 950 XL and 550 again for updated Windows 10 builds. Early builds had, among other things, significant battery issues.
after the scandal with 950 and windows 10 bugs I taught I will never upgrade my 640 to win10.but I upgraded and it works well to my surprise(actualy win 10 with 1g ram works decent in normall applications).like the reviewer comment,we want a really nice midranger with some 2g ram and some nice camera+some better processor.
[deleted post]This phone has nothing different than all the other WP with WP10.
This review should have been on the Time Saver Edition.
