Airplane mode consumes battery??

[tresbubu]

Hello,
I apologize in advance for my bad english.
I have a question to ask:
I have an iphone 8,
I have updated the last available , I know that my phone loses about 4% in airplane mode in 8 hours! Another my iPhone 6s 0% in 8 Hours?why?
I deactivated:
Localization
updates itunes
icloud backup
app updates background
Handoff
restored to dfu 0 app charged

if it is left in 100% charge mode, it loses nothing for the whole night! Why?

iOS 11 problem or it’s normal?
I'm the only one?

Thanks

Hi tresbubu

The answer may be in relation to how Airplane Mode works in iOS 11 as compared with earlier versions.

In earlier versions of iOS, Airplane basically shutdown everything; but you could selectively activate Bluetooth and/or WiFi. Next time you used Airplane mode, it again shut down everything.

With iOS 11, if you use Airplane mode, it does shut down everything, but if you activate Bluetooth or WiFi, it remembers this for the next time. So, next time comes along and you go into Airplane Mode, but Bluetooth and WiFi remain active.

You have to shut them down yourself.

That may explain the differences you are experiencing. When you use Airplane mode in iOS 11, check that Bluetooth and WiFi are also shut down - and that goes for anything you turned on previously in Airplane Mode - it will be remembered; whereas before iOS 11, Airplane Mode shut down everything each time.
