My iPhone 5 is Acting Weird?

Ok so a few weeks ago my charger started acting up. Originally I just had to put it in on a certain side to charge my phone, then it had to be on a flat surface and now its just not working. My phone was on 13% with the faulty charger in and suddenly it went to 1% and then died. My top button is broken so I can try turning on my phone either, I just want to know that if I go buy a new charger and plug it in, it will turn on as usual and you don't think the battery was messed up from it suddenly going to 13% to 1%.

IPhone 5S Cellular Data issue?

Every time I try to open an app that uses Wi-Fi or data it says " *so&so app* has not been given access to cellular data" or something along those lines & doesn't let me access the Wi-Fi data…

So how come it won't let me use the data on other apps?
I've gone to settings to turn the app on for the data & allow access to the data but it still doesn't work!

What's the issue here?
