Well, this is yet another issue I have with my NEW Mate 20 Pro.
Put down the phone last night at 11:23 (I know because its the time of my last message to the mrs!), and it was on 100%, took it off charge and picked it up this morning......27% battery left!!!!
Now that's a SERIOUS amount to lose overnight considering it was doing nothing!
I am now getting very disappointed in this so called 'flagship' phone, as this is the 3rd major issue I've reported in as many days
I do hope somebody can help as I am ready fro chucking the phone out the window I'm getting that frustrated with it.
