To me, calling out a minor detail that doesn't change the point of the post comes across as petty. Just compare the size of the battery of Samsung's first LTE phone in North America, the
Galaxy Indulge (
3.5" screen, 1500 mAh battery, 3h talk time) to the
Galaxy S5 (
5.1" screen 2800 mAh battery, 21h talk time) Obviously there have been numerous improvements between the two (including battery tech), but the increase in screen size plays a major factor in allowing the phone to have a battery with nearly twice the capacity.
Not convinced? Just read this review on the 4.3"
HTC Thunderbolt, the second LTE phone in North America. The early LTE phones got poor battery life. This didn't really improve until they got bigger (closer to 5" screens) or thicker, or in the case of something like the RAZR Maxx, both (but got really good battery life). Searching through the complete history of smartphones is a tiresome exercise, but you want to do it, you'll see that my primary point is pretty damn applicable.
I don't mind calling people out on relatively minor details when everything they said was nonsense, but when it isn't, all you end up doing is obfuscating a valid point. I could have been more polite in responding, and simply acknowledged that "whole reason" wasn't technically true ("major reason" would be more appropriate), without the rest of what I said. However, I tend to respond in kind to the comments I receive. Petty comment gets petty remark.
