Weird battery drain on copper?

[wolven]

Hey,

I guess I have a weird question:

When i upgraded to copper, i also started using spb shell. Nothing else running task manager, I make sure wifi is disabled unless im using it, yet it still eats through battery life like crazy, when just texting. ( talking during a 15 minute break at work, it'll drop 5% in battery power ). Is this normal?, or are there any tweaks I can do to lengthen that? I like my phone to last at least 24 hours between charges
