So starting today... my usage has been the same as my standby... which I assume means that ever since my iPhone has begun it's new "cycle" since the full charge... it's been "working". Normally I'd go through a charge cycle as almost 2 days of standby and 8-ish hours of usage; however last night my battery drained nearly 15%, and I noticed my usage increased to 17 hours... indicating that it had been active overnight. That I guess has continued today, since my usage and standby are both near 3 hours.... what is going on all of a sudden?! What apps may be running in the background and why?
