I have had this HTC One M8 for five months now, and it still impresses me I have owned 13 different Android flagship phones the past five years, and I would put this One M8 at the top, especially if running the 'GPE' version. Great design, amazing build quality, awesome sounding stereo speakers that are loud and clear, it's warp speed fast, gorgeous screen, and the battery life, wow. I just installed a fresh 'GPE' ROM on Monday, and look at these battery life results, this compares to my old Galaxy Note 2, which was a beast on battery. I unplugged my phone yesterday off the charger at 6:00am, and didn't charge again until bedtime at 11:00pm. I got 6h On Screen time, and total usage of 17 hours. And it was a workday, so major use nonstop for work, two hours of phone calls, hundred texts, GPS Navigation, plenty of web use looking up Vendor sites, etc... And most of this was on the 4G LTE network, only a couple hours of this on WiFi. I was hammering on this phone all day and night, HEAVY use.
