[Samsung Galaxy Note 10+ Questions & Answers] sendvic:
Hi

I have a week old Galaxy Note 10+ with excessive battery drain over night (2,5-4+% per hour). I did a factory reset after first noticing and it was fine for a nigh. Installed some apps, and it was fine sometimes, sometimes not. This night it was the worst with 4%+ battery drain per hour.

Battery historian graph looks like this:

View attachment 5148205

Wifi, mobile data and bluetooth were turned ON.

Battery usage/ samsung Batetry tracker show no apps with excessive usage.

BetterBatteryStats show frequent wakeups from com.android.phone Alarm.

batterystats revealed this behaviour all through the nigh:

There's 23K+ of +wake_lock=1001:"*telephony-radio*" and 7k+ of +wake_lock=1001:"*walarm*:com.android.internal.telephony.data-reconnect.ims" in 8 hours.

Can someone help me determine the reason for this? Please let me know if I can provide any more data.
