Why did they have to remove the sound profile widget??? It's so funny how something like that was actually thought of to be removed. I do however like how they added the flashlight app. It's not just in the dropdown menu anymore.
I was to busy to use my phone much this weekend, so I only had 3 hours of SOT, but this allowed my battery to last 32 hours. I don't do anything special to improve battery. I do keep my screen brightness about 1/3 of the way up, but this is only because that is where I like it. I don't use powersaver at all, even when it kicks in at 15% I promptly turn it off. This is an improvement for me with heavy standby time and light usage. I will test battery with heavy usage this week.
