May I assume that most of "you" follow the common sense idea of closing apps on iPhone to save battery charge?
That has been my understanding.
About two months ago, I visited the Apple Store and a helpful tech troubleshooted my 7Plus... gave me a new one. and then added this. He said, it saves battery life to NOT CLOSE THE APPS as most of us have been led to believe !
I was on the phone last week with a calendar issue, and the Apple person told me she disagreed with the Apple person who told me NOT to close the apps

Opinions ? And what is reasoning behind your opinion? In my case, I know little about things computer, I am just curious.

Extra redundant stuff As an older person I am almost getting used to 100% conflictual ideas such as CO2 good, bad... USA good, US bad, Milk good, Milk bad, Spinach good, spinach bad... World is going to freeze, world is going to boil. vitamin good, not too much vitamins, playgrounds of 60's good, and bad, Montessori good, bad... coal good, coal bad, fluoride good fluoride bad, Vaccine good, vaccine not so good, AI good AI bad. Body building bad, Body Building good, religion good, religion bad, Tofu good, Tofu bad, Humans good, humans bad... ad nauseum.

Call me old or stubborn but I tend to just do as I please. I quit worrying about what others say years ago and just go my merry way. :)

If the day comes I need a new battery I will have it replaced, and when my phone needs a charge I do so. Life is too short to worry about trivial things.

I don’t close apps to save battery. I do it because iOS memory management is imperfect and doesn’t jive with my usage. Apple’s devices just don’t have sufficient RAM to guarantee no reloads so I kill the apps I don’t need and just keep the ones I do.

Well I can tell you this:
On a ram starved iPhone 6 Plus (1GB of RAM), if I launch a whole bunch of apps and delegate them to the background without quitting them, I can definitely notice a difference in performance with the phone. It's less responsive. Annoyingly so.
In fact I can then go to the notes app and start typing and the keyboard can't keep up with me. I'll finish typing a few words then watch the keys I previously hit slowly highlight and finish what I typed out.
It's ridiculous.

I doubt most people close apps to reduce power consumption.

Many people do it to maximize the amount of available RAM. I think it's relatively well known that closing apps increases power consumption. But some people, especially those with 2GB devices, are more concerned with performance rather than battery life.

I bet the OS is built around the idea that force quitting apps is only needed in troubleshooting scenarios or in very specific use case.

I never force quit an app if its not misbehaving.

There are numerous other threads on this subject in these forums as well as other on line sources. The consensus on all of these threads is that no one agrees regarding closing or not.

Closing them or not closing them makes no difference either way.

i always close every app and turn off Background App Refresh for all except emergency info related apps.
better able to completely control what they do and when they do it.
this way i don't need to cripple an app's location functionalty and i set Location tracking to "When app is is use" for a lot of apps instead of leaving it off.

i don t have the problems some people are reporting with Mail not pushing. it pushes just fine even if not open and no Background app refresh for it.

app Push notifications work just fine.

limiting which apps get to place Notifications on the Lock screen stops the display from lighting up in not needed notifications and conserves battery greatly.

For quite some years, Apple's advice has been to not close apps unless they misbehave.

The only thing that should affect battery usage when an app is off-screen is whether the app performs background operations. You can see what apps do that in Settings > Battery.

The definition of what apps are open/running has a lot more to do with its settings than whether you've force-closed the app. Force-closing does not stop features like Notifications or Location Services. Apps that are intended to be running in the background will do so, regardless of whether they are "open" or "closed." (In the case of Location Services, set apps that use Location Services to "While Using" rather than "Always" in order to minimize background activity.)

Yes, a misbehaving app can affect battery life, but when an app behaves normally and it does not perform background operations, there's no energy use at all, whether you force-close or not - it's just sitting dormant in Flash storage.

I never close apps and its been fine for me ever since I been using iPhones since the 3GS.

If you really want to test this - when you go to sleep one night check the battery percentage, don't close any of the apps and when you wake up check the percentage.

For the next day, do the same test but this time close all the apps and compare if it made any difference.

Yes, "I had been told" bluetooth is best off in terms of battery. "The survey SAYS"! lol
Sure it will have a tiny impact if just on and idle. I use Bluetooth for the watch and my AirPods daily and honestly don’t see much if any impact in my daily usage.
