Yeah, my stand by battery usage was good last night. Went to bed at 51% and woke up at 49%. I'll see how it goes for the next few days, but so far it seems good.
I also dropped the display scaling down to 300% on my XL and I like that it changes the formatting on some of the apps. Most notably in Messaging, where now you can switch between contact threads without backing out in portrait mode. Not a huge deal, when messaging more than one person it's nice to be able to switch conversations without hitting back every other message.
~9 hours later and I am at 75% - sporadic use.
I don't feel a "drain" so far but let's test it further.
