So is there a reason why my standby time goes up, while I am using the phone?? Like right now I am at 2 hours and 30 minutes of usage since my last charge, I am using my phone obviously right now typing this, at the end of this post both my usage and standby time went up another 2 minutes, and my standby time goes up, even when I am using my device...is something wrong?? Is that suppose to happen, standby time going up even while I am using the device actively??
