Currently my mate 10 still not received any update, hopefully after 28 October will received it.http://www.techradar.com/reviews/huawei-mate-10-pro-review/2
"In our battery tests involving continuous HD video playback at full brightness with WiFi connected, the Huawei Mate 10 Pro lost just 9% of battery after 90 minutes, ranking it above any other flagship smartphone currently available (Galaxy S8 Plus lost 11%, LG V30 13%, Galaxy S8 lost 23%, iPhone 8 Plus 23%)."
some good news after software update by huawei.
