I've been running on ParanoidKangDroid quite happily for about a year or so now before I've started questioning battery life. It was brand new when purchased.
It used to run what I'd consider fairly well, not having a 'real' smartphone before. Compared to my friend's Note 2 that lasted a lot longer, I just chalked up to battery size.
Lately I have noticed that it is ridiculously short. Once I started looking into it I have been seeing people with 15h life and 3-5h screen time. That's insane, at minimum brightness I usually get 1.5h, maybe 2h screen time max.
I've checked wakelocks, I've checked for physical battery bloat, I've now installed S3rx 4.3 Touchwiz based ROM cleanly, all without solving my issue. I don't let it run dry, I top it up frequently in order to not **** the Li-ion battery out of capacity. I've checked threads out for ideas and tips to no avail. Notice that there isn't any games sucking it dry, as I don't tend to play them!
I realise that my mobile signal isn't the best in some cases, but battery life remains same with similar usage at home or anywhere with consistent full reception. I'm just stumped. Later tonight I'm going to move-on to PAC-man or Carbon Rom, as this Touchwiz crap is driving me batty, and try a couple different kernals.
Without further ado I present thee my photos. Any suggestions?
