The battery life of any smartphone is usually a sensitive topic. The designers have to balance battery life with phone size because battery capacity is pretty proportional to size. Some people prefer huge phone with huge batteries while others like me prefer our phones small and tide so they fit well in our pockets.
Anyway, because of the capabilities of todays smartphones, battery life is very much dependent on how you use your phone. Whereas I am a stickler for shutting down everything when not needed, others might like to leave everything on and synching all the time. Difference is I get 3-4 days while others get 1-2 days. from the same phone and battery.
Have a look at the link below for steps you can take to manage the battery life of your phone a little better.

I think you will find that battery life is poor especially for the high end phones which usually consume more power because they've got bigger displays, faster cpu's and they do more. You will find the same problem with all the different makes across the board. I have the current top end phones from 4 different manufacturers and they are all about the same. Symbian phones tend to have smaller batteries but then again, symbian is more frugal compared to some of the other OS's.
The root of the problem is battery technology which has for a better word stalled over the last decade. While devices are leapig ahead, the lithium ion/polymer batteries have not really changed much. Hopefully this will change soon.
For the moment, poor battery life is an issue every smartphone owner has to content with.
