There's a difference between battery life and battery longevity. The Galaxy Note 7 had a fairly beefy 3500mAh battery, but Samsung tried to cram too much capacity into too little volume. The unconventional pack shape created a substantial risk of internal shorts. Poor thermal management or aggressive battery management can vastly increase the rate of battery degradation, but they're non-obvious and most tech journalists don't have the knowledge needed to identify those issues. Most consumers don't understand battery technology and don't know what's available on the market. They go into their local cellphone store and choose whatever looks nice and is recommended by the salesman. They aren't aware of handsets with bigger or user-replaceable batteries, because the industry hasn't really offered them the choice. I use a Chinaphone with a giant battery, but I have a lot of knowledge that no average consumer has.
