I keep updating my iQOO Z9 to the trial version released every month. But the battery draining problem has never been solved. Then I saw many people saying that it's because of the trial update and if I update to the stable version, I won't experience battery draining problem. If this is true, when will the stable update for the August month will release for iQOO Z9? It's been three days after trial update got released....Should I wait for the stable update?
