Battery Test – CVPCS 7×125-1000 SV

***Update*** Phone is is being replaced vis warranty….

I have decided to try and test battery life of different kernels. I hope these tests will give some insight to whether or not there is a big difference between low voltages (LV) and standard voltage (SV) kernels. For now I have included results (see links) for one kernel and will be including another this evening.  As always, comments/feedback wanted.

The test will be performed as follows:

  1. Fully charge the battery with a wall charger
  2. Delete /data/system/batterystats.bin
  3. Start a battery tracker with 1 minute logging
  4. Set the screen to 100% power and no timeout
  5. Start the movie using rockplayer, volume = 0 (How to Train Your Dragon)
  6. Unplug the phone from the charger 7
  7. Wait for the battery to read a minimum of 70%
  8. Stop the test
  9. Pull the log data for the battery and use the data from 90% down to 80%
The kernel will be overclocked with setcpu  with the minimum and maximum clock speeds selected. ( IE- 125-1000) The govenor will be set on demand.
