My thoughts as well. I despise that every new phone can't last a whole day of heavy use without a charge. It is the pits when I'm at a music festival or some other event and my phone starts to die midday. I just need access to my favorite apps and an OK camera, I'd give up almost every feature other than those for stellar battery life. Other features are great but let's focus on battery life.
If it's just an occasional problem, I'd suggest getting one of those USB battery packs. You can get something that will recharge your phone 3 or 4 times for $40.
Look at all these amazing features....you will need to turn off in case you want to actually use this as a phone....
