Htc m9 vs samsung s6 battery thoughts
So here is what I understand
SoC - htc has snapdragon 810: 20nm process, samsung has exynos 7420: 14nm. Process shrink usually points to better power efficiency. But I don't imagine at idle or using the a53 cores will make a lot of difference between the two
Display - m9 has 1080p slcd and s6 has 1440p samoled. Pushing more pixels requires more power but amoled has certain power efficiencies also, I tend to believe pushing less pixels would be more beneficial
UI framework - m9's sense 7 seems like a light skin. Touch wiz seems to be lightened up too. But with all the extras samsung puts into touch wiz I would say sense 7 is better on battery.
Battery capacity - m9 has 2840mAh and s6 has 2550mAh. But also comes down to how it's used in the system. If user plays games a lot, I would imagine htc with more capacity would win out.
In my opinion, it's really not cut and dry. I think samsung trying to go after the fruit company made a mistake by making the phone too thin, and sacrificing battery capacity. Probably why they keep touting how quick the charging would be along with wireless charging. Htc increased battery capacity which was a good idea but not sure if it's a major increase. I used a Nexus 5 with 2300mAh and it was notorious crappy. I switched to an lg g2 with 700mAh extra capacity and it made a lot of difference in daily use. M8 to M9 only sees a 200mAh increase. Without seeing what people say when the phone's are available I think I would have to think it may be a wash and both phones would probably last through the day. Although I would bet on the m9 if I had to choose. Sorry for the long post.
