Pocket Edge hibernation test

syclone · 10-03-2011, 11:45 AM

Three or four weeks ago, when I received my second Pocket Edge from Woot, I updated the new one (PE #2) to VER.1.01 of the Ermine OS. There were some questions about extraneous apps running on Ermine like the telephony apps. I had renamed the telephony apps on PE #1 to *.bak, didn't do it on PE #2 although the 2 apps appear in the files. I decided to do a hibernation life test on both units to see if there was any difference.

It looks like they are as nearly identical as you can get. The battery curves tracked each other almost perfectly. The last entry (with the *) was recorded by powering up the units with the battery charger hooked up . At some point, 8% or below the units both powered down on their own.

This is in no way a scientific survey, as you can see from the wild variations in observation times. But it does seem to indicate that the PE can go ~10 days in hibernation without a problem.

I apologize for the crude appearance of the chart. I probably should have converted the data to a JPG file and attached it.

DATE-------- TIME---- PE #1------PE #2
22-Sep----- 8:48 PM--98%------- 100%
23-Sep-----12:35 PM-- 93%-------- 95%
23-Sep-----11:18 PM-- 89%-------- 90%
26-Sep---- 11:49 AM-- 61%-------- 63%
1-Oct ------10:00 AM-- 21%-------- 23%
1-Oct------11:00 PM-- 16%-------- 18%
2-Oct ------ 9:40 AM--12%-------- 14%
2-Oct ------ 2:30 PM--10%-------- 11%
2-Oct------- 6:00 PM-- 8%-------- 9%
3-Oct * ----- 8:00 AM-- 8%-------- 8%

This goes along with what I've been saying:
telephony apps never appear in a list of running apps (Manage Applications -> Running) or even processes (Dev Tools -> Running Processes).
In my test I only got 170 hours, but I did use my device a few times for short periods, even using WiFi (the biggest drain).
From your post it's not clear what OS you run on device #1.
Your results is definitely with margin of errors, actually too perfect. I would even accept wider spread, e.g., 5%, as showing no impact.

Pe #1 was running Ermine 0.9, rooted

I was amazed by how well the two PE's tracked each other. The only real difference between them other than the OS Mods, were that PE#1 has been used since Mid-July, PE#2 is only a couple of weeks old and it's battery probably has not been aged in yet.
