    Because of my stupidity, I left my phone charing at night and some how fell asleep and left open a flash light application, so basically my flash was on for hours and hours and my phone couldn't die because it had a charger plugged in so it kept going, and just to put the cherry on top, I fell asleep on top of my damn phone! This caused my GS4 to get extremely hot and I woke up for school and realized that this could be bad, my battery especially was very hot and I removed it from the phone and a little later I put it back on and charged the phone. What I noticed was my phones battery drained throughout the school day and I was not happy about this because I was quite frankly enjoying the longevity of my battery life! So now I suffer bad battery life despite using battery savers! What's also as bad is that my phones performance got worse! It studders and lags much more than usual, and the gaming performance is also now laggy! This is so horrible because I was truly enjoying this phone so much it was so amazing until the incident :( so I was wondering if I replace the battery for a fresh new one will my phone be back to normal in battery life and performance wise? I keep wondering (sorry if I'm ignorant about this!) if the battery life and especially the phones performance is based upon the battery? Is it based on the battery or the internal phone??? Please help and thanks for reading!

    The phone will slow down and/or get large if it reaches above a certain temperature. It will then cut some of the processors power to try and cool the phone down, even if the source of the heat was from the battery or if someone lives in a hot country.

    I don't think there is any way for someone here to tell you for sure whether or not permanent damage was done to your phone. I'd GUESS that the battery needs to be replaced, but that may not fix all of the problems you're having now.

    If you know someone else with an S4, ask them if you can borrow their battery for a while (I'm thinking 20 minutes or so). If you don't know someone, ask at your local cell phone provider store, they may have a demo S4 you can borrow the battery out of.

    Power up and see if your phone is working correctly with the different battery. You won't be able to test it long enough to know whether or not it fixes the problem with battery life, but you could find out whether or not the phone is working the way it did before.

    Just but a new battery, the phone should be fine, you probably damaged the cells in the battery.

    I say buy a new stock battery as well. (Never get in bed with devices charging either.)

    Does anyone know if it ruins the gaming performance?

    Why would a new battery ruin the phones performance:thinking:, and again, no playing video games in bed with your phone plugged into a charger, you can keep it plugged in overnight, but make sure to leave it on your night stand, not under your pillow.:D

    I would say the answer is unknown as Podivin suggested. It's not obvious what is causing the poor performance at this point in time. Low battery voltage ordinarily does not translate into low bus voltage since battery voltage (3.5-4 volts dc) is electronically transformed to a lower regulated level like 1 - 1.3 volts dc.

    It could be battery is so damaged that the phone can't even produce a normal bus voltage and what he's seeing is similar to effects of severe UV'ing where CPU must go back and repeat operations because they were not successful the first time. (Do you have an app that can read your battery voltage?)

    Or it could be the damage goes beyond the battery.

    It's definitely worth trying out a new battery. My swag guess is much better than 50% chance that'll fix it fwiw. Hope for the best and be prepared for the worst.
