Can it be that call recording drains a lot of battery? After 1 hour of calling I lost ~8 to 10 percent of battery and media scanner has a bigger wake time than calling (without scanning media or playing music). And in battery statistic I can see that the call eats my battery as fast as when my display is on, but during the call it was only on for a few moments.
With stock rom (without call recording) I lost 11 percent battery in 3 hours when calling, so it was around 3,5 to 4 percent per hour. Now it eats 8 to 10 percent per hour and that's not good for me
