Since I upgraded to a 4.3 based M.O.A.R. 9 my battery life decreased dramatically. I've always used Battery Monitoring Widget to keep tabs on the consumption. On 4.1 my idle current draw was 30-40mA, on 4.3 it is rarely below 100mA and I can't even get close to 24 hour standby. I asked about it in the ROM thread and was told that this is an inherent 4.3 problem. Is it really that bad and I need to go back to 4.1 or I can try something else- maybe a different ROM, or completely erase and rebuild everything. I tried to freeze or remove potentially offending apps and it didn't help. My wife has S3 with 4.1 ROM (also M.O.A.R.) with pretty much the same apps and she has no battery problems.
