I mentioned a couple of weeks ago I'd do a battery drain comparison on the PW4.

Anyway, results are in. Threw in a PW3 and KT4 into the mix.
Initial charge was noted on 7/23/2019 around 10-11am. Final charge was noted on 8/19/2019 around 10-11am.
- PW4 5.10.0.2 factory: unregistered, shutdown: 100% - 97% = 3%
- PW4 5.10.0.2 factory: unregistered, airplane mode on: 100% - 95% = 5%
- PW4 5.10.1.3: unregistered, airplane mode on: 100% - 95% = 5%
- PW4 5.10.1.3: unregistered, airplane mode off: 98% - 92% = 6%
- PW4 5.10.1.3: registered, airplane mode off, deep sleep: 99% - 91% = 8%
- KT4 5.11.0: unregistered, airplane mode off: 98% - 89% = 9%
- PW3 5.8.11: unregistered, airplane mode on: 99% - 73% = 26%
The PW4 on deep sleep is without Special Offers.
I think I might have bungled up on the PW3 test, though. It was on screensaver but I apparently left KUAL running (to check battery status) so I don't know if that prevented the device from going to sleep. Then again, the PW3 was a refurb purchased from Woot and based on serial number, has a manufacture date of 9/12/2016 so it's quite possible battery on that is degraded.
