Depends on the kind of phone you're looking for. Smartphones tend to drain more juice than usual. If you don't mind the size, then get Galaxy Note, I guess? If you don't mind paying extra, then check ZeroLemon for batteries. I bought one for my SGS3 and it is amazing. It's on 9% battery life and I charged it to full on Friday night. I'm not even sure if 9% is accurate or not, as it showed lower percentage but after a while of screen off, the percent went back up.
If you don't want a smartphone, then Nokia, I guess?
