I'm not sure why some of you are getting such poor battery life. I'm getting better than 30 hours on my Original Razr, and the same on my wife's Razr. I got about 16 hrs on ICS...
I may be a little more frugal than most with battery and data. I don't have 'Unlimited'.
I run WIFI at home. I toggle it OFF when not in use.
I run WIFI at work. I toggle it OFF when not in use.
One the phone I follow advice given me by an old Captain 30 years ago...
'Son, if you ain't got nuthin to say, don't say it on the radio'...
I apply that advice to talking on my Razr.
I run 4G away from home.
I did a couple of FDR's, and use 'Smart Actions' to help save battery.
I re-calibrated my battery also.
I run my battery down to about 10% at least once a month, cut off the phone then charge it over night.
When I re-installed my apps I also updated them
I don't use my Razr as a radio.
I don't use my Razr as a game machine either.
I keep GPS OFF until I need it.
I don't use an Interactive Wallpaper.
I have my phone set to stay on 1 minute, and when I'm done, I hit the power button and turn it off.
(I don't shut it all the way down)
Now days, I am on three forums, I do a number of e-mails daily, I do a bunch of text daily,
I do several phone calls daily, and I probably take fewer than a dozen photos a week,
if we aren't traveling or on vacation. I don't watch many videos either.
I'm not sure how everyone else is using their Razr's, but some combination of the above
gives me great battery life, my wife follows the same procedure and gets the same results.
