Did you recalibrate the battery after installation?
 
no, because i don't think it is related.
the problem of v.2.04 is sleep mode. the machine can't really go to sleep at all, even though the screen is off. from battery meter, the screen (strange enough that the screen is actually off most of the time) and wifi are always on. it can be proved by simple hand touch on the machine back. on v2.04, the back is still warm after a few hours of sleep. on v2.03, the back is always cool in sleep mode.

 

Without trying, then you can't rule it out Belleville! So here is my report since instaling Darth's zip, and after follow up mod. So far with the new rom and the mod and after 18:15:35 on the battery is at 31% usage on sleep mode, with a few wake ups to go online to look in on the archtablet forum. Wifi was active. Phone radio did consume 91.5 % of the power used, wifi 0.8%, screen 3.0%, held awake 2.9%. power left 69%. I did do a calibration when I installed your zip Darth, but not after the follow up mod.

Just a simple physics question, how can a machine get warm when idle? If not from the battery drain, where does the heat come from?

I didn't try to recalibrate the battery, but didn't mean that i didn't try anything. I tried a lot of rom ver all the way from v1.05 to v2.04. each ver of the rom, i tried original and a bunch of custom roms modified by different people as well. More than a dozen roms i tried already. I never recalibrated the battery, and had no problem until v2.04. both original and custom v2.04 roms, including kasty, darthjabba (with and without mod), a couple of chinese custom roms, had the same battery drain problem. Once i get back to v2.03, my machine magically become cool again in sleep, and no battery drain of course. Now, it maybe only 1-2% lost for 12hr standby. Did i recalibrate the battery? No, never.

I don’t mean all machines are the same. It may be just my own case.
