If this is real, I recommend doing as others have said and get your battery checked out. I had the 11 and its battery is pretty phenomenal. I watch a couple hours of YouTube, play an hour or two of COD, listen to music at the gym, and send tons of texts/iMessages. I consider that heavy and taxing usage on the battery. It still can get me through the majority of the day. The 11 Pro Max will probably get you an extra hour - hour and a half or so above the 11. This is my experience after owning all 3: 11, 11 Pro and 11 Pro Max.
