I wouldn't doubt it.
I don't use any underclocking/overclocking things.
No sense. I like my phone just the way it is.
(I really gotta update my phone in the profile thing to my TP)
I have no problem with battery life.
I'm usually on the internet around a total of an hour/hour and half at work,
that's basically my 2 15minute breaks, and my 1/2 hour lunch that sometimes turns into an hour. haha.
And then I'm playing music atleast 75% of the workday,
sometimes streaming for a good half of the time I'm playing music,
I usually work 10 hour shifts too,
I like to use commas instead of periods when on forums,
don't really know why,
just thought I'd throw that in there,
but at the end of the day I usually still have an hour or two of battery life
before it gets down to the 10-15% range.
oh, and I'm using the stock battery...
