Yes, I‘d say it depends - if the app executes stuff in the background or not.
If it only does its job when actively opened then the remaining time the extra space it takes on your iPhone doesn‘t affect battery life.
If it performs background tasks, uses Wi-Fi, mobile data, bluetooth, GPS or pushes notifications, THEN removing this app (or disabling background activity) improves battery life.

edit: Also some apps can still drain the battery although background activity is disabled if they use a specific API like CallKit for VoIP apps.

Thanks makes sense.

So if I installed 100 apps and made sure it did not perform background tasks, uses Wi-Fi, mobile data, GPS or push notifications having that many would not effect battery life at all right ?

That‘s my experience and what I imagine it to be.
I updated my 1st post with one exception:

But in “system settings > battery“ you can see what apps are responsible for battery drain and you can act accordingly and disable additional stuff in a specific app that stands out.

Cool. Thanks.

Oh and make sure to disable automatic app updates because in this regard more apps lead indeed to more battery drain (Settings > App Store > Automatic downloads)

Good idea.
