My Test for battery drain CM10,1 R15 Vs Fusion X beta 7 (at the time of the test)
once again sorry for my poor english, but I think my test could be interesting.
I have tryed this 2 rom in only 2G test, I use my Y300 as a "Motorola startac mode" alias as a old phone of the 90's, no gps, no internet, no radio fm, no mp3, no torch... simply in 2G with 2 short call and 1 sms every day, 16 hours active and 8 hours in aeromode. Allarm active every morning.
Fusion X Beta 7 (the version available at the test time) reach 20 days of usage as you can se here
CM10.1 R15 (the version available when I star my test) reach 14 days of usage as you can see here
Cyano is more drainy rom than the stock or stock based as Fusion, I foud a issue concernig the notification led blink, if you loose a call it start blinking and cpu is to minimum (196mhz) but not stay in deep sleep and this is drayning the battery 3% for hours. I think the same appens when battery is under 10% , i deacitave the red blinking but I saw my battery passing from 9% to 3% in just an hour, I think even if is not blinking the blink mode is active and cpu pass from sleep to minimom voltage and this increase the battery drain a lot.
But even if this issue is solved the difference is more or less 20-25% between Fusion and CM in 2G
