i9505 Poor 'screen on' battery life
I've got brilliant screen off battery life on my SGS4, but soon as I start using the phone the battery just plummets.
I took my phone off charge, went to the bus stop, started at 100% and finished on 89%. Total off charge time 19m, screen on 12m. That's 1% every 2 minutes!
I'm sure it's not a background task, my phone goes into deep sleep most of the time. Checked CPU usage and nothing is up, got brightness to lowest and all extra features off and power saving on. I had 70% left yesterday after being nearly asleep for 13hr.
Using Golden Eye 8.0 ROM. XXUDMI1 bases with Adam kernel 1.6 and baseband XXUDMG5. I've used other ROMs to no change.
Went down by 7% just writing this!
