On my OnePlus 3 it worked fine. On the OP7t with Oxygen 10.0.12, this app is questionable. The charting is completely useless for battery charge. It shows flatline when charger is plugged in. Sometimes it will correct itself much later (hours) but usually it plots some nonsense graph with asymptotes in charge or discharge. If the phone says it has 90% charge, this app might show 98%. Hitting Refresh might work and might not. Refresh never makes a difference with the charts. I have very little confidence in the app anymore. I will keep it on the phone in hopes that the dev will come up with a fix.

The best app out there that I've tested for battery monitoring. Except for the notification UI - hard to figure out. Learn from my frustration: Even though they make the same sound which can't be configured, notification sounds and event alarms are not related. Otherwise you'll be putting up with noise for EVERY SINGLE % CHANGE of the battery during charging and discharging if you also want to be notified of boundary conditions like overheating.

Love the app. I enjoy watching the rate of charging. The app helps evaluate the different chargers or cables. Gives me important info about the discharge rate. The graph let know about the excessive discharge rate that is often the result of some leftover garbage in the RAM. That is an indication that it is time the reboot the phone. Changed the rating to 2 stars. Why does the app requests permission to manage and make phone calls?
