How long are the calls, if they are like an hour long each then probably not.

I use Whatsapp, IM+, couple of texts, 1.5 hours of music + browsing and 10-20 minutes calls a day. I have around 60% remaining before I put it on charge again.

I do keep my Wifi off when I'm not using it (Whatsapp and IM+ through 3G), so that helps.
 
If the call is 5 hours, it probably won't last all day.

Mine lasts all day with some calls, games, texting and browsing mixed in. If yours doesn't, either exchange it for one with a healthy battery or delete some of that porn you got on there. Porn is to phones what casinos are to time. You look at a picture and then back up and it's 3 hours later, your pants are down and you're in front of the dinner table with your whole family there staring at you in horror
 
when i have to open where i work at 5am my battery lasts from 4:30am till i go to bed at 2am the next morning. (insomnia)
 
i noticed facebook can make my usage and standy by times match...whether it's using battery and not just a glitch...idk. but from my short experience the battery has drained faster when i noticed this.



also when i put my phone in my locker i could drop 60% in 8 hours of work...i put it on airplane and will hardly lose anything
 
Let me also join the list of people who have no problem with it lasting a full day.

My typical day is 5-6 hours of web browsing, texting, streaming videos, taking a few pictures, and calls, 12-13 hours of standby and it's rarely under 10% when I plug it in at night.

The only exception is if I'm actively using the GPS or playing an intensive game.


This wasn't the case before I upgraded to 5.1 so, if you haven't done so already, update and see if that makes a difference for you.
 
I'm in the midst of transitioning from a galaxy s2 to an iphone 4. After having used a few android phones over the years, the superior iphone battery life is one of the biggest differences I've noticed so far. Granted, I haven't used it much for voice calls yet, but been playing some music and using data on and off (browsing, fb, etc) and I am AMAZED at how long one charge is lasting me. Even on standby, I don't think my galaxy s2 ever went over 24 hours on one charge. The iphone is at 85% after 22 hours of being on. Again, it's been on standby for much of this time, but still - none of my old android phones had anywhere NEAR this kind of life.
 
If you are having poor battery life , do the following .

1) lower your brightness and set automatic brightness
2) enable restrictions and disable ping
3) disable fetch on email.
4) disable a lot of notifications for unnecessary Apps
5) disable wifi when not using it
6) be sure to close apps when not using them (double click on home button)

And I think that's all.

Big one:
7) Stay in range of 3G signal.
