I'm a moderate user and couldn't get through a full day w/o a charge on this Note 4 which has a massive battery. The point of my post is people will never be satisfied w/ a battery until it lasts all week. They may be at first but eventually they're going to want more. I wouldn't say it's an issue over people being greedy about the onscreen time they feel their phone should have. Not only that, what you do w/ your phone, as you know, has the biggest wear on the battery. If I'm constantly playing Clash of Clans all day, sure, this thing will die quickly even w/ a 4k battery. If I'm just browsing the WWW then it will last all day. You could call it an issue all you'd like but how many people have made drastic changes to their battery size and structure? Sure, they're biggest as the phones are bigger but you don't see companies getting 5k size batteries yet b/c people are whining it's not big enough. Why?
And I never said no one couldn't vent their frustrations. It's just a simple, playful jab at people who post about batteries 60% of the time. They will not be satisfied even w/ the number the battery size says it is.
