Problem With Samsung A40 Battery Charge

[smurfchops]

When I turn on my mobile the right hand corner always says 100%charge. You can sort of see another number underneath unless I press the face of the phone then it is a clear 100%. However when I log in it tells me the true charge which isn’t always 100%. Hope you understand my description! I have switched the phone off and on again but still have this weird problem. Thanks all.

What does it tell you ? Putting load on can reduce the voltage reading immediately.

You may have a failing battery. Of course these days you aren't able to simply open up to get at it. (I wonder what the real reasons for that might be.)

It’s quite a new phone, not quite two years old ... l can live with it, but it’s odd ....
