phone app high battery usage

Yes a qualified tech, but obviously not a genuine battery as the phone won't report battery status. However, I've had two years of perfect function. Only to have it go from 50% to 0% instantly.

but like i said. I turned off the cell radio and that seemed to fix it. The phone was reporting that the phone app was using 65% of the battery, and I never use the phone. So something was keeping the phone app cranking away doing who knows what.

The phone has been operating normally for the last two days now. I barely get to 70% by the time I go to bed.

Thanks all!

The battery was replaced mid 2021. So two year old battery. the phone does not show the capacity remaining.

The battery meter shows that the phone was at 50%, then shut down, and after that it started consuming power.

Today I shut of the cell radio, and the phone stopped discharging quickly. I left the radio off all day, and now that ive turned it back on it seems to be back to normal. Strange.
