IPhone 6s battery not connecting properly?

I was attempting to replace the battery on my iPhone 6s yesterday. I got the old battery out but when I went to put the new one in I was having difficulty securing the flag looking object (attached to the battery), to the phone. It only seems to want to click on one side. Any suggestions on how I can get it to sit properly?

Could we have made this technological advance sooner?

we're living creatures with brains their are hundreds of thousands of people that help and create tech advances we all make mistakes we could always be more efficient with our time. Could we have quit possiably created SmartPhones sooner?
The biggest break was june 2007 with the iPhone and its unique interface and tech. After as all companies do is compete. Today we have a wide range of cell phones similar to the iPhone and were accustomed to it. With that being said. Is it not very possible that we could have created the iPhone/smartphone 10 years sooner 1997. If you take a step back from 2017 to 2010 we had for instance iPhone 4s/5 it had a retina display still quit a impressive gadget that's only 13 years from 1997 so could we have done better was it theoretically possible for our mind to handle at the time (in your opinon ofcourse)?
*LASTLY - beyond the possibility of the smartphone being created 1997 vs 2007 had it been created in 1997 would it have to been done by steve jobs from Apple?

its always interesting to know what could have been done sooner.
THANK YOU

2010s we're seeing breakthroughs in tech so when?

I'm no expert but I know things like the invention of iPhone, APPS, AI, CGI have changed so much we're using smartphones to do so many things that wasn't possible in the early 2000s or before. However all of our devices are projected on a screen its a physical object. How far are we from leaving platic and screens to virtual/hologram immersive experience? Its hard for anyone 2 say but with the current tech and the progress weve made since the beginning of 2000, could this be 1decade,2,3,5 or 8,10+ ? We all love entertainment whether its games,movies,music but todays standard iPhone x with the best audio outpout you can use to give it an effect still doesn't cut the idea of a truly digital device that can change and replicate in you hand and give you the feel of being for instance in a virtual place experiencing your media. So yea any thoughts, please?

I don't know what's wrong with my iPhone 5?

I recently got my iPhone 5 fixed as I accidentally dropped it and smashed the screen. It has been working completely fine until just now when a dark purple colour wiped across the screen and turned the whole phone off before restarting itself. It just happened again as I'm typing this.

Any advice?
Added (1). It keeps on happening now whenever I try to use the phone. Also, the battery is constantly jumping up and down.
