I have a PC laptop without SIM slot so it can only connect to the internet with WiFi or physical lan cable.

I'd like to know if I use my iPhone as personal hotspot to create WiFi for my laptop,
very often I need to use my laptop for a couple of hours continuously. Would this create any heat issue to my iPhone or age the components inside the iPhone much faster?

Because I also have a pocket WiFi device, but I want to bring less thing around
 
There should be no problem using your iPhone as a hot spot for your notebook PC. As long as you have a good cellular connection with your phone it will work. And no, it does not create heat or wear out your iPhone. I use my iPhone on occasion to create a hot spot for my Mac and my iPhone remains cool.
 
It will use up the battery somewhat more as the phone will be used as a modem/router essentially.

It's said Lithium battery has no memory and all myths about Lithium battery is just myth. Why it would use up the battery somewhat "more" when the phone serves as a router....?
 
He means that using the phone as a Wifi hotspot it will drop from 100% quicker as its a power hungry process. You may need to ensure the phone is fully charged before starting or be able to plug the phone in to recharge it whilst you are using it as a hotspot if required.

I'm not saying that it will really affect its lifetime usability or something like that, just that the battery charge will get used up quicker while you are using the device as a hotspot compared to various other uses (which can at times also make the device warmer too, depending on how the usage goes, as can be the case with some other usage, like some gaming, etc.).

Also, more as a side-note than anything, while the memory effect doesn't apply and there are various myths about batteries (li-ion or otherwise) that are around, there are still realistic things that can affect battery health to one degree or another (for example, heat is one of those type of things).

Yes, I wish to know if an iPhone serving as a WiFi hotspot would make the iPhone inside hotter than usual....and thus affecting the battery life

It can, like running some apps at times can make a device hotter at times than usual. It's not a given or something that would happen across the board for everyone all the time, but like with any other use it can happen.

I'd be more worried about burning up my data plan than I would about burning up my battery.

If you do not have unlimited data for tethering, here is something to consider.

Your laptop will connect to your iPhone as if it were a wifi network. No big deal, right? Except if you have settings for wifi connections that may eat up data. Let's say that you're using YouTube and that your settings for wifi are to stream in 4K. Well, that's gonna chew up data. It's probably more of an issue when tethering with phones and tablets, rather than computers as those types of settings are more typical for mobile apps.
