It's normal. Above 80% you'll lose your first % in 9 minutes or so. After that, and depending on how good a connection you have, you should be losing 1% for every 2-3 minutes of usage.

That indicates to me a dead battery. I have a 4s and it is 3 years old. AFter ios 8 came out (or just coincidence) I would lose 1% per minute. With my own "normal" usage, the phone would be dead in 2 hours.

I just replaced the battery yesterday and since 3 hours (180 min) I've only lost 34% and I'm streaming music via bluetooth and occasional texting.

XT550-- I would suggest changing the battery. Go to ifixit.com, buy the battery and repair tools (about $25). It takes 15 minutes. they even have a step by step on how to do it. It's so easy a caveman can do it!
