I broke my iPhone, can i still backup my photos?

I recently broke my iPhone 5 with iOS 9. It's only the screen that doesn't work, rest of the iPhone works fine. The screen lights up however i can't interact with it. When connecting to iTunes it says i have to unlock my phone to get acces to the content. Is it too late to backup now?

Why can't I charge my iPhone through XiaoMi 5000 powerbank?

I reset my computer which is Windows 10 and it kinda reverted back to factory mode so I re-downloaded iTunes, and I plugged in my iPhone. Anyways, the point is that I can't seem to properly charge my iPhone with XiaoMi 5000 powerbank using XiaoMi's powerbank cable with an Apple adapter. It was okay for the first few seconds then it keeps indicating that it's not charging even though the cable was still connected. Is it because of the Windows 10 messing with my iOS systems or is it just because of external factors like the cable? Cause before I reset my computer, it was fine, then problems start arising after that, yet if I use Apple's original cable, there's no such problem. Can someone help me cause bringing along the Apple cable wherever I go is so troublesome cause of its length, so I prefer XiaoMi's cable

Iphone memo, if I don't careful things get deleted. How do I prevent?

When I delete, it's slow first then it's faster
then it's instant all delete.
so i have to stop holding delete after a while.

This not the only problem.

Sometimes accidentally I touch the screen
something gets deleted and I don't remember what it was.

Need something like undo delete.
(Everybody already know how to restore the WHOLE memo but not the few words.)
