Yes(via Wifi), the modem is one of the biggest battery drains in modern phones. The shorter the period the modem is open, the longer the battery will last. A phone manages this quite well and only keeps the connection open as long as need be. However a modern computers wants to keep a constant open connection and will make many requests in the background even if you're not browsing the web so it is a lot more strain on the phones modem than if you were doing the same tasks on the phone itself.
To get around battery issues, connect the phone via USB when tethering instead of using a wifi hotspot. The trickle of power will keep the battery topped up.
The OP is referring to battery health, not battery life.
OP: Hotspot should not have a negative impact on your battery unless your phone gets very hot. Heat is a battery health killer. If you notice your phone warming up, I recommend stopping the hotspot and letting it cool off for about 15-20 mi gets before proceeding.
Hotspot should put even less wear on the battery than regular use, since the screen is off and the phone will run cooler.
The radios and processor are the primary heat sources. Actively using the phone as a hotspot will heat it up more than just having the screen on.
This and the phone will go through more charging cycle as the battery depletes faster and more often.
If one has to tether then it’s better to make the connection via cable and only use it as an absolute necessity not on a regular basis.
Maybe but the processor is hardly being taxed when just hot spotting, I use it all the time and the IP7 runs cold while on hotspot.
Certainly no more strain on the battery than normal use, biggest generator of heat IMHO and experience is charging LOL
Actually any wireless radio depletes battery faster than the processor itself.
Who cares? Use the crap out of it to get as much value as you can and replace the battery if it goes bad.
Avoiding using the device because you are afraid of lowering battery life is absurd.
but they are connected. Batteries only have so many charging cycles before the internal chemicals degrade to a point of being useless. with iPhone batteries it's up to like 1000 cycles which usually lasts folks a good couple of years. but if you use the battery more, with like tethering, you drain the battery faster resulting in a need to charge the battery again. this means having depleted a charge cycle quicker.
thus the answer is correct, tethering will decrease battery health more
I never get the whole argument of preserving battery health. Use the device as you need to. If the battery goes bad, replace. Sure you don't want to leave the phone out in direct sun or put it in the freezer to charge. Starting a car battery in extremely cold weather really does harm battery health, yet nobody calls into work to say that they aren't going to be able to make it in because they don't want to damage their car's battery.
Right? It's like buying an off-roading truck and taking special care to make sure you never run over manhole covers on the street to protect the suspension.
Never had heat issue with my iPhone. I use it daily for several hours none stop and it stays cool. I have it plugged in to a charge the entire time.

No it won’t. While tathered, the phone will stay fully charged, thus no wear on the battery.

But your still using data from your cellular... so even if display is off, hotspotting would be the same as using your iPhone for cellular. (but from an connected device)
This is not necessarily true unless someone is using the cable for hotspot connectivity.
