After running the battery to 0% and charging for ~7-8 consecutive hours a few times, I believe my battery ought to be conditioned by this point. After using Battery Monitor to override the max battery capacity setting from 1530mAh to 1900 mAh, I've been noticing significant longevity gains compared to the stock HTC battery.
Yesterday I had it off the charger for about 14 hours of the heaviest use I've put the phone through since I got it, including:
~4 straight hours of streaming radio (over WiFi)
~2 hours of playing music
~1 hour of 4G surfing in an Ikea warehouse with, at most, 2 bars of signal
~30 minutes of Skype videochat (over WiFi)
-Tons of Google Maps while running errands in an unfamiliar part of the city (no Navigation though)
-Default Auto-Brightness
Today, my usage has been much, much lighter. After 8 hours off the charger, I'm still showing 76% on my battery. Pretty awesome if you ask me.
Don't know if this is useful for anyone else out there, but hopefully people are seeing similarly dramatic improvements in longevity with their Anker batteries.
