How to stop IOS 11 battery full beeping

This is by far the most frustrating thread I have ever read. On one side multiple people, myself included, are posting about exactly the same fault symptoms. On the other there are basically 3 people who refuse to accept what they are being told and keep insisting that the posters have faulty phones/batteries/chargers or whatever. Let me make this perfect clear. With so many people posting about exactly the same issue then it isn't bloody lint in the charging port! I'm an engineer working on very high tech equipment and these reports would be sounding alarm bells right back to our factory. OK, you haven't seen the problem yourself. Lucky you. Lots of other people have though, and just mindlessly repeating the same advice is totally unhelpful.

What we do know is this. The phones affected are at 11.2 or higher. It seems to mostly affect wireless charging. Multiple charging devices are producing the same effect. It's a bug and Apple need to acknowledge and fix it. The workaround posted by one user is so far the only useful bit of advice.

For the record I have a 1 day old iPhone 8 Plus with a brand new Dockall D100 charging base and it pings when the battery is full and the screen displays the full battery icon. And there's not a speck of lint anywhere!
