S4 bad battery life issue

[Vdmman]

I don't know what is going on, ive had this phone for 2 months now and ive witnessed horrid battery life.Playing on a game for about an hour and having it idle for two hours brought the phone from 94% to 33% (how do I post screenshots btw?)

Welcome to the forums!
What game, and how long have you had it?

Bloons tower defense battles, 2 days, but even without having any games on it, its just as bad. Games only make it a tad bit worse. Also, massive battery drains overnight when idling. It will drop from 80% to 50% overnight. Defective battery?

WiFi and data will drain your phone over night fast as well as other apps that may not close properly so overnight just leave on charge , battery life with allot of screen time is low as its full HD screen turning brightness off can help this though

I am not a heavy phone user and with minimal browsing, 2hrs maybe, a day of FB, 10 emails, 4min call. My battery is from 6:30am to 7pm. 5% left. That is with WiFi ON.
WiFi OFF, in about the same amount of use, at 7pm i still have 45%.
I do have the zerolemon 7200(?)mah (EDIT: 7500mah) battery. With all S4 features turned on and games, it should last you a whole day. Be prepared though, its thick and HEAVY. But worth it if you need that much juice.

Yeah, but the thing is, if I have wifi off and brightness down to as low as possible and leave it idling for 11 hours, when I get home its down from 100% to 85%. Thats doing ABSOLUTELY nothing but idling. And also if im doing internet surfing for about 30 minutes its down at least 10%. People say they can internet surf for over 8 hours, but according to battery stats, im getting nowhere bear that. About an hour of gaming and its from 90% to 30%. Is this normal?
