Trying to take off iMessage?

So my dad has an iPad and I have an iphone and my iMessage was linked to my moms email and my phone number and our iPads was linked to my moms email too. My dad just figured out how to turn it on so he can monitor my messages and it notified my phone when he turned it on. So I went to my settings and took the email off my iMessage so it's only linked on my phone number. Will all my messages still get sent to my dad's iPad? Also does it send the texts from people without an iphone to the iPad too?

Why is my iPhone 4S battery so bad?

I know iPhone battery isn't good in the first place but seriously. First off my iPhone doesn't even fully charge by the time it gets to like 95% it doesn't charge unless the phone is off. My brightness is always low, I always close apps, I never play games. I do everything that supposed to stop the battery draining but nothing works. It's like every time I stop paying attention to the battery it goes down by a percentage. This absolutely sucks I can't stand it. My battery isn't broken or anything it's fine. But the battery is really bad. Is there anything that I can do that can significantly help battery life? Like at least 1% goes every 3 minutes. Even over night when I don't use it, around 4% goes which isn't much but at night the brightness is the lowest. Wether the brightness is high or low the battery life is ******* ****!

IPhone 4s Wi-Fi connectivity?

I have a wireless router which is about 5 years old.

When accessing apps which refresh new information like instagram or mail, with Wi-Fi connected, the loading wheel spins forever without loading anything. In order to load I have to turn off Wi-Fi and then updates are made through 3G. Is this a problem within the iPhone or router?

Added (1). This only started happening recently. Wi-Fi is setup correctly, when I load a webpage it works fine.

Iphone is a brick after update?

I updated my iphone 5 to the latest Ios (ios 7.0.6) and when it was about to restart the phone went blank. The low battery icon shows up so I charged it for several hours and nothing happens, I let it charge again overnight but it has not improved. I tried resetting the phone but it won't let me, the annoying low battery icon keeps popping up. Even Itunes doesn't recognize the phone anymore…

Help?!

Added (1). I charged it for almost a day but it is still low on battery:/

Added (2). It's never been Jailbroken at all, just to let you know.

Can The iPhone 4 still run alot of games?

I plan on buying my mates iPhone off him soon as he is upgrading to a 5 and is selling his iphone 4 to me for £20. I already have a samsung phone so I don't intend to replace the iphone with my existing phone instead I just wish to play the ios exclusive games and put a bit of music on the phone. However I know the iPhone 4 is quite a old bit of kit now with all the newer models out so my question is will I be able to run the majority of the games on the iPhone? Or is it too outdated and i'll only be able to run the lower spec games

Added (1). Does it have gyroscope aswell? As I hear alot of games use that now
