Are the iPhone 5c and 5s charging ports the same?

So my iPhone 5s has a problem where it won't charge unless i angle the usb cable up. I have made sure that it has nothing to do with the cable itself. I do have a spare 5c and was wondering if switching the charging ports would be okay? Does the fact that the 5s has the finger print home button and the 5c doesn't make a difference?

Has my text messages been seen by recipient?

Yesterday I sent someone text messages using my iPhone (they use a different mobile brand). They have not responded. Have they seen my texts

There a two time stamps in the green bubble messages I sent.

1st message - says Yesterday 19:00
2nd message - says Yesterday 22:00

Has the person looked at it received the messages? I have a suspicion not because they normally group messages together by day but instead mine has separate stamps.

Any help appreciated.

What should I do if someone hacked into my Apple ID?

Last night, someone went into my Apple ID. This person sent a plenty of abusive messages to my contacts. I know I didn't do it, because I was just busy watching videos while that person was sending messages. So I have blocked all my contacts to keep low from this person. Well I used to a iPod touch and I lost it last year in my school. After when I lost it, someone must have found it and went inside that account. So is there anyway I can do?

Added (1). I own a iPhone 6S btw

How to access the majority of storage on my iphone 6 plus?

I keep unloading all the pictures I take but for some reason they are all kept in a copied form even if I format the phone.

So every time I unload all the stuff on the phone I have a little less space to use. Until this last time it only let me save about 50 images. Then after I unloaded the phone, it still has less than a gig free. And I keep getting that annoying advertisment about adding more space for a fee. F that. I just want the space I should have.

How do I navigate beyond all this nonsense and actually delete everything since something is preventing me from doing that via formatting?

Is the iPhone 6s camera flash any good?

I've had so many issues with the iPhone flash in the past. Night photos have been blurred and pale. Can someone tell me if the new iPhone 6s flash is any good?

Problems with health app? (6s and iOS 9.2)?

Hi so I got an iPhone 6s yesterday and it is completely updated but I'm having trouble with the health app. It doesn't count my steps or anything. I put everything on the dashboard and they are there but they aren't changing. I've quit the app and opened it again, which still didn't work AND then it reset my medical id? I also got an app that counts steps and that works but the health app still doesn't. My phone isn't showing up as a source in the health app.
