The device has the firmware with which I bought it in early February. I dare not update it, although it constantly reminds me, precisely because everything works perfectly and I'm afraid there will be problems. The cable is charged in about 2 - 2.5 hours, and the battery heats up. To keep the rubber seal on the usb connector, I bought a wireless charger in the beginning. With it, charging from 20 percent to 100 takes about 12 hours, but the battery lasts significantly longer. This morning I picked it up from the charging station, it was 100%, now at the end of the day it is 96%, but I had almost no time to use it. Greetings!

Hello, Does the phone have OTA upgrade?

I show pictures of the current firmware and the upgrade that comes out, but I do not dare to install.

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.
