Is clearing RAM on iPhone safe?

I want to clear my RAM memory, but I need to make sure it's safe and I won't damage my phone. IIm using the method where you hold down the power button then the home button.

It won't, RAM holds data temporarily and clearing it will not damage your phone, i'm not an iphone user but i can tell you this!

It won't hurt anything but really there's no need to do that.

That doesn't really clear the RAM. If you hold down the power button then the home button for a short amount of time it just restarts the phone forcefully (called a soft start). Doesn't really hurt it, but not really necessary. But if you hold them too long you risk putting the phone into DFU mode (called a hard start) where it erases everything and you'll have to restore it using iTunes on a computer. These methods are generally only used if the phone is having issues performing actions

Yes that's fine.

Yes it's not damaging to the phone, but you don't need to clear your RAM. Please don't install apps that do this though, they mess up the operation of other applications on your phone. And Also must install LEO Privacy Guard v 3.0 app in your smart phone which is free available in iTunes, to secure your iPhone, also a battery life saver.
