PW4 battery drain test

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.

What are the conclusions? I see
- shutting down significantly decreases battery drain
- wifi does not affect the drain (in sleep)

Thanks for this extensive test.

Would you consider doing a repeat of the PW4 deep sleep test with airplane mode on?

Is there a difference between usual sleep (10 min timeout or button short press) and Screen Off mode (via menu - 7 sec button press)?

Sure. Currently testing deep sleep off, airplane mode off, though so it'll take a while before I can get to that one.

Didn't test. All were either timeout or button short press. Not something that's quick to check. The above test was ~27 days. Doubt there'll be any difference though.

What exactly is the difference between shutdown and deep sleep, and how does one go about putting the Kindle into those modes?

Shutdown is like power off on a tablet. Only jailbroken kindles can be shutdown. One way is the shell command
Code:
shutdown -h now
Deep sleep is not yet understood by the user community. It might be something like hibernate.

Thanks; didn't realize the shutdown mode was tied to jailbreaking.

My battery drains a considerable amount with Wi-Fi on and in "sleep" mode. Interesting difference.
