IPhone 4 battery drains within minutes?

I have an iPhone 4 and I've never had issues with my battery until recently for some reason I open an app my phone will be fully charged and within minutes and I mean like 2 minutes my phone shuts off saying it's dead has anyone else had this problem with any of their iPhones

BATTERY WAS DEAD!
CHANGE IT NOW.

Maybe battery is old and needs replacing. This has happened to me before. Had to replace the battery.

It might be a firmware glitch, do a factory reset and see if the problem persists.

If the phone does the same after few resets, it might be the battery and you need replacement.

Battery was dead!
change it now…

You need to charge it with original charger and If problem persists, you need to consult the techincal department of Apple and I would like to recommend you the best security app that will be useful for you to secure all your media and that is LEO Privacy Guard v 3.1.2
