How do I keep enough power for a full day of basic use when it is running out fast?

[iMore Question]

I phone 6 - 9 months old - recently seems to lose power very quickly. I only use it for email and web browsing, some photos, texts and calls. I need it to last one long day of traveling to NYC and back by bus, and 6 hours in the city, including phone calls, photos and a bit of browsing. I am afraid it will be dead before I get back and need to make a late call.

Go to Settings...Battery and see what apps have been doing... Consider double-tapping the home button and swing up on apps you're not using and are using lots of battery... and consider a case with battery power...

Welcome to iMore! There are a lot of things you can do to maximize battery life. Some ideas can be found here: http://www.imore.com/tag/battery-life

I also recommend keeping a portable battery charger around. Here's the one I have and it works great:
