S4 Batter Help

[dodg33rman]

My battery for my S4 has been dying within like 3 hours and I was wondering, are there any batteris I can buy that will last longer but will work on a standard case? Like a battery that isn't bigger than the default one?

The battery shouldn't be dying in 3 hours unless you have a dozen apps running, the screen at full brightness, the flashlight on, etc., etc. If the phone is over 6 months old and you regularly let it run down until the phone tells you to recharge it, it's probably at end of life and you need a new battery, not a larger one. You also need to not let the battery get below 40% charge. (If that doesn't give you enough time, buy a spare battery or two or more and swap batteries when the one in the phone gets down to 40%.)

Constantly fully discharging a lithium battery can completely kill it in 6 months or less.
