Sorry OP, but you seem to have missed the point completely about the non removable battery. The problem isn't whether the battery will last a day or not. The problem is the battery, at some stage WILL die. At which point the phone has no resale value whatsoever, whereas before you could sell it on and put the money towards your new phone. It doesn't matter how efficient the processor is. This is going to happen. As said before in multiple threads, Samsung didn't have to sacrifice premium build with the Note 4 to keep the removable back, so there's no reason they couldn't have done the same with the S6.
