So, I have a Motorola Moto G4 (https://www.motorola.com/us/products/moto-g) that's about 1 and a half years old and has worked out like a charm so far. I've noticed, though, that the battery has been draining a little bit quicker than a few months ago. Usually, it would take two hours to drain at least 30% of the battery, but has recently been really draining more in an hour tops. The phone is not charged constantly (usually about once or twice a day), I have all apps closed, and I even turned down the brightness a tad (with the adaptive brightness still on, because the phone is virtually unreadable otherwise). The only time I have anything on that can cause quick drainage is when I have my VPN (Opera VPN) on when I'm on public wi-fi, which is not that often in the day (1 hour tops on public wi-fi). Any advice on what I could do to diagnose what's going on with the quick draining?
