Some stuff that bothers me, based on my usage.
Battery life isn't as good as the S4, I expected this however because I knew this phone had a smaller battery. But I feel the drop in battery life is worse than I expected. What makes this more annoying is the fact that charging this device TAKES FOREVER. If I am using it as a GPS device, whether it be Waze or Google maps. I can't even get it to charge. It will either hold it's charge or loose some. This is with a 2amp car charger.
Other than that, I love the slightly smaller screen. 4.7" is a good stopping point. haha. And the speakers on this thing, wow. It's not insanely louder than my S4, but the clarity is insane for a phone. Love it.
Display is superior than that of the S4 as well. I don't know that I will want AMOLED screens anymore.
Sense trumps Touchwiz, I think we all knew that. I almost want to say I prefer this look than Stock AOSP.
Now if only I could get root, so I can remove the Verizon bloat.
