They only look stupid to people who care more about fashion looks, those people tend to be a bit childish to begin with.
I agree. What's the point in having a super thin cool looking phone if the battery will only last you 8 hours? Sure, the iPhone is cool and thin and so are other Android phones out there but turn on that GPS, the WIFI, make calls, text and I can assure you , by 2pm (if not earlier), your phone will go on panic mode and ask you for more juice.
This is no lie, I have had my Note 2 turned on with GPS, WIFI, calls, texts, since wednesday. It is Saturday now and I still have 71% battery left.
Does the Hyperion battery make my phone a little thicker on the back? Yes, but who cares. I don't have to worry about charging that sucker for days.
FWIW, my understanding of battery technology today is that, much like defragmenting a solid-state drive, 'training' is an obsolete practice and could potentially cause harm. It's being dangerously encouraged by the Android hacking crowd that's been using custom recovery modes which offer a "reset battery stats" function, where users are instructed to run the battery to zero then full to 're-teach' it its limits.
Feel free to correct me if I'm wrong.
The Hyperion battery comes with a manual and on the back of the manual it says:
"For full battery performance, please discharge fully and re-charge at least 5 times."
