Suggestion: You can save the data to verify the factory settings. There are two ways to do it: one is OK after restoring the factory settings, and the other is to shut down one night after charging, and it is OK after booting.

Can Admin please advise whether battery drain is being tracked on the 9800 Pro and whena firmware fix might come? It's a great phone if you can fix this.

If I install the update and a problem occurs ... for example, as my colleagues run out of battery, what can I do then?! .... can I go back to the old firmware version in any way?

And and update to the latest Android version so we can have dark mode as that should help save battery life.

mine version is 1412 too
