I love my Maxx! I have been getting better than 24 hours of heavy use daily and at times close to two days use.
I am currently working in a large ER that is for the most part underground and gets very poor signal. In a few places I can pick up a weak 4G but usually get marginal 3G at best. We have wifi, to I turn off data sync and GPS and turn off WiFi (I have Smart Actions set to do it for me when I get to work).
The funny thing though is how much I "rib" everyone about their iPhones and other Android phones..... we have several charging stations throughout the ER where people leave their phones plugged in to charge. Most get much less than 8 hours.
So last night, this doctor came down looking for an iPhone charger. Of course it was being used so one of the nurses told him "that'll be $10.00." He replied with "but I only had to pay $5 yesterday", she replied with "weekend rates". Love it!
So I just show everyone the battery indcator on my Maxx and watch them weep.
