A developer over at XDA wants to try to figure this battery issue and high Android OS usage out so he asked me to make a post regarding a test he would like us to perform. Please follow the instructions below to help out -- the first part everyone can participate in and the second part requires root, but even if you are not rooted please help out.
TEST INSTRUCTIONS
ROOT INSTRUCTIONS
If you are rooted, please perform the following two steps after finishing the steps above:
Thank you for your help!
Edit: If you are rooted, you can run the commands above from a terminal emulator but just type "cd sdcard" first since the / directory is not writeable. The three text files will then be in your SD card for emailing or pastebin'ing.
TEST INSTRUCTIONS
- Reboot phone and charge to 100% or clear battery stats in recovery / bootloader.
The user needs to clear their battery stats before they start the test. Either clear it in bootloader or charge to full, then unplug. People are starting at 78%, and AndroidOS is factoring in their other runtimes.
- Turn on Wifi (make sure "Always On" is set).
- Let the phone run idle with screen off (turn off background data if possible) for as long as you can. Even go watch a movie and leave your phone alone.
- If you get an urgent text or call that needs answering, try to let the phone go back to sleep for at least another hour or so.
- After this time has elapsed, please grab a screenshot of your Android OS usage (after clicked, showing Keep Awake time). Also note how much battery percentage you lost in this time.
ROOT INSTRUCTIONS
If you are rooted, please perform the following two steps after finishing the steps above:
- Load adb shell
- Run the following two commands as su:
cat /proc/kmsg > kmsglog.txt
cat /proc/interrupts > interlog.txt
cat /proc/net/netstat > netlog.txt - Grab these two log files and paste them into pastebin.com and then PM myself so I can forward them.
