Buy extra chargers to keep everywhere you go and get one of those cases with an extra battery built in. I'm not a heavy user so my 4 hours was mostly on standby. I sat in a grocery store parking lot once waiting for my wife and in less than 20 minutes of reading the news on my phone I watched the battery go from 85% to less than 10%. I get my phone through work and the Iphone is the only option they support. If that weren't the case, my iphone 5 experience would have been enough to get me to switch to android. Good luck on 19 more months with yours.
