how do i add a widget to tirn off wifi in IOS 11?

You can't add anything to iOS. This is how Apple chose to manage Wifi/Bluetooth, so you can:

1. Turn it off in settings

2. Ask Siri to turn it off

That's it. You have no other options. Apple doesn't consider this a bug, and neither do I or anyone who recognizes that having the Wifi/Bluetooth receive on and ready to connect easily to a network or device is not only smart, but frankly a great idea.

How can I easily restore the true “off” function using a widget or a button? Or, is there a bug fix slated in an upcoming release to fix this ?

To answer your two questions. You cannot add a widget or button to Control Center for this. You can turn it off with the switch in Settings.

There is no way for any of us to know if there is a fix, especially since it isn't a bug, it is working the way it is designed, as described here. Use Bluetooth and Wi-Fi in Control Center with iOS 11 - Apple Support

No that doesn’t answer the question.

Yes it does: You can't add a button with that feature. If you want to turn WiFi off, you will need to go to settings.

Leaving WiFi on and not connected uses a negligible amount of battery. If saving battery life were my number one priority in a phone, I'd still be using my LG enV3.

This change is very much in keeping with Apple's very apparent idea that the iPhone is an always connected device.

How is cause and effect grasping at straws?

Correlation doesn't prove causality. First, you need to proof that the cause is what you think it is. Lawrence has explained why you're incorrect in your assumption of the cause of your battery drain. And the rest of us have refuted your arguement with our experiences.

Bottom line: you can't turn off WiFi or BT using the Control Center. You need to go through settings (or Siri). That's the way it is. No one here can change that. You can submit feedback to Apple telling them of your displeasure.

Tell me how to test it. At any given time there are dozens of things using energy on your phone. So it is impossible to tell the effect of any one of them, Wi-Fi and Bluetooth included. I guess you could reset your phone, set it up as new, don't install any apps. Don't create any email accounts. Don't log in to iCloud. Don't browse the Internet. Put it in Airplane mode, then turn on Wi-Fi only. And leave the phone without using it at all for a few days and measure the battery life. Then repeat the test with Wi-Fi off for the same period of several days. Measured exactly, to the minute. This is about the only test that might be meaningful.

So, given that you can't determine it empirically, the alternative is to do it analytically. Which I have done and posted in detail in another thread (I should create a user tip from it). It's based on the energy requirements in the IEEE 802.11 standard for WiFi and 802.14 for Bluetooth.

I won't bother to repeat it here, but the bottom line is that if the only thing using power on your iPhone was unconnected Bluetooth and unconnected Wi-Fi the battery life would be on the order of weeks. So whether it is on or off will make no measurable difference in the battery life of your phone.

Anecdotally, In the 10 years I have had iPhones and iPads I have never turned off Wi-Fi and never turned off Bluetooth. I charge the phone overnight, every night, and my phones have gone through an entire day without having to recharge, unless I spend many hours on the phone. Today, for example, it is a little after 10 PM, and my iPhone 7 Plus is showing 44% battery left. And I've been using it heavily on mostly cellular data throughout the day. Usage was 7 1/2 hours, standby 14 hours.

The original question was about how to more easily turn off Wi-Fi.

Also, radios on high power search mode take a lot of battery. This was reported in the original post. You can just test this yourself by walking around the city or driving with the radio in search mode, and then again with it off. Check the battery at the end of the day in both instances, and you will demonstrate what the original poster wrote.

You are confused. CELLULAR radios use a high power mode when searching for signal. Wi-Fi do not. CELLULAR radios that are not connected to a network send polls in an attempt to find a network. They start with a low power signal (50 mw). If they do not get a response, they gradually increase the power, as far as 500 MW. If they still do not get a response they wait a minute, then repeat the process. If they again don't get a response they wait 2 minutes and try again. They keep increasing the time interval between polls. This is why, when have lost signal for a few minutes it takes a long time to reconnect unless you enable Airplane mode for a minute to start the search over.

This is ONLY true for cellular connections. Wi-Fi does not work that way. Wi-Fi just listens for networks for a couple of seconds every 15 seconds. It does not poll.

Your test is absolutely worthless. There are several dozen things that use energy, so singling out Wi-Fi is impossible. And, BTW, I walk around (or drive around) cities all the time. I never turn off Wi-Fi. And my battery life is exceptionally good.

It's time to end this argument. You have chosen to believe what you have chosen to believe. We can't help you in any way, as you refuse to accept logic or experience other than your own, which is flawed.

Idris said it best above. This is the way Apple has decided to manage Wifi/Bluetooth settings in iOS11. You clearly don't like it. so your options are simple:

1. Switch to another platform altogether

2. Let Apple know you don't like this

Arguing with us is meaningless and a total waste of time. I will not reply to another of your ridiculous posts and I encourage my friends here to do the same.

I don’t want it on because it uses battery.

Naah. If you really want to save battery energy, turn off cellular data and keep it off. Cellular data (especially in a weak area) is a real power hog.

Something I always have trouble getting through to people.

By the time all the myths about batteries, battery charging and battery life have been laid to rest, we'll have a completely different kind of battery and we'll have to start all over again with the education.

Gentleman, you can simply leave your Wi-Fi searching for a few hours and watch your battery drop, compared to having it off. There is no question of this.

Looking for helpful answers only.

I never turn my WiFi off. I don't have any problems with my battery.

Nor any of the iPhone's we've ever had. In fact, I've never turned off Wifi/Bluetooth. Never. It doesn't make sense to do so and leaving them on, improves the performance of services, such as location services, etc., that it's never made sense to turn them off. If Ghgdgjhf is having battery issues, he needs to look for the real reason, because it certainly isn't because of this setting.

Is it searching all the time or connected? Have you compared against having Wi-Fi turned off, if it is searching? It should have a dramatic affect on your battery.

Wrong, wrong, wrong.

I don't need to test it. My battery lasts all day with lots of use.

Why are you making such a big deal about something that isn't an issue?

I get that you don't like the new way Apple is managing Wifi/Bluetooth. Either get over it or go to another platform. You're whining here isn't going to change anything.
