[OnePlus 5 Questions & Answers] ArnoutVos:
Yesterday evening I had reached 2 days on one charge (93% to 8% = 85%). SOT of 2h30m, light usage throughout the days, 4-5 hours from home, ~1 hour of Bluetooth paired to the car. Very well.

Conclusion

So no long-running wakelocks. I already installed Whatsapp and no problems so far. Conclusion for now is to not restore your apps on first boot setup. I think some garbage or data is also coming through during restore of previously installed apps causing strange, seemingly unrelated, hard to diagnose wakelocks.

I will now gradually install most-needed apps, and measuring if any problems will occur.

At night, with doze enabled, the drain was around 0.7% per hour:

#75: +1h30m24s943ms to 83 (screen-off, power-save-off, device-idle-on)
#76: +1h41m7s261ms to 84 (screen-off, power-save-off, device-idle-on)
#77: +1h44m21s184ms to 85 (screen-off, power-save-off, device-idle-on)
#78: +1h34m24s250ms to 86 (screen-off, power-save-off, device-idle-on)
#79: +1h34m14s644ms to 87 (screen-off, power-save-off, device-idle-on)
#80: +1h9m5s927ms to 88 (power-save-off)
