Galaxy S4 vs DNA

That's my biggest issue with a locked in battery.
Also, we know, batteries only have so many charge cycles.
So what do you do when each progressive day, your battery holds less and less a charge?
If you had a removable battery, you could just swap it out for a new one.
 
If I had it to do again, I would take the DNA over S4 no questions asked. I dont like touchwiz or the look of samsung phones in general. Not to say they are bad phones, just not my style.
