Needless to say it was needed for my phone.

has this process worked for you for every device you've owned? I'm getting horrible standby drain on my m8. Wifi on, location, autosync, bluetooth, nfc all disabled. in a span on 9 hours I lost 10% close to 11. the only thing I can think of is I haven't greenified anything, but I shouldn't have to..

and like another user said I seem to get better battery life when it is in use then when it is in deep sleep

1% battery drain per hour is about normal. If you don't want out to drain turn it off

According to HTC tech support, the battery in the One has a chip that tracks charging/discharging. This chip's memory is cleared via the specific steps I outlined (both volume keys and power button cycling). It's important to do this process while the phone is plugged into the HTC charger that came with the phone--not an aftermarket charger. Apparently, the charger chip is also affected by this reset.

I performed this reset procedure a few times, cleared the device cache, did a data reset, and also installed the new OTA. None of these steps completely corrected my erratic battery behavior. I'm sending the phone back to HTC for a replacement. In researching this, it appears that after the prior KitKat OTA several weeks ago, a number of folks have complained of the same power problems on various Android boards and I believe HTC is aware of the problem.

Its an electronic device that is running. Should it be magic and use no power. At 1% per hour thats 100 hours of standbye time which is not bad. I agree you should be maybe a little less with all location services, data, 3g, wifi, bt all disabled but remember. Its on and using power, it has to use something.
