No, that's your point. The battery life is terrible unless you're basically using the phone like an iPod Touch. Listening to music off local storage over BT and surfing predominately over WiFi likely without much SoT (and certainly not in sizable chunks of SoT).
His post matches up to what I stated earlier in the thread, and what you basically agreed with...
While earlier in the thread you stated:
To which I would respond... Of course. Even my 4th Generation iPod Touch got "great battery life" on WiFi and using only a Chat App and Facebook.
Most of us buy a smartphone to use it when we aren't tethered to a WiFi connection, and to do more than send tiny text messages and post social updates
The only thing that matters to me, as far as battery life is concerned, is how well a phone does on the cellular network during normal day to day usage. Those are the situations in which power actually limits what I can do with the phone, or how long I can use it. I don't care if my phone reaches 20% when I'm on the couch. I simply plug it in and grab a Laptop, or go to my PC. I do care if it gets to 20% at an Amusement Park, because when it's dead, it's dead and no one is going to wait around an 30-60 minutes for me to charge my phone - if I can even find a place to do that. If I'm on WiFi, there's a 75-85% chance that I can simply plug the phone in, anyways.
Of course, situations differ (different countries, places, lives, schedules, etc.). For me, that's basically how it works.
