Extreme and Rapid Battery Drain on S4 Mini

[AlleyCatCY]

I have the stock 1900 mAh battery, and experiencing Extreme and Rapid Battery Drain on Galaxy S4 Mini.

Even at idle, exploring settings can have a battery drain of 20% over a span of 45 minutes. At other times, the battery can drop one percent every second. I am unlikely to get more than 3 hours of use out of this phone.

How old is the battery? If it is more than a year old that could be the problem. Do a search for "battery" in this forum and you will find plenty of questions and answers about battery life!
