Anything with a Li-Ion battery does this.There's no doubt in my mind that it reaches 100% charger faster than my iPhone 4. However, is 100% actually completely full, or is it more like 95% and it just says 100%, only tricking up to 100% at a slower pace? I think I read that in a few difference places... but I don't remember the purpose.
Edit: NVM...first part was wrong.Th only thing that I have noticed so far is that the battery life is great AND it stays at 1% forever before dying. On a side note, I have a USB car charger port in my car. It charges my iPhone 4S just fine but not my 5. Is it because the lightning port actually needs more energy to charge??
Similar times here, definitely faster to charge than my 4.Let me just say this, I let my phone die from previous 100% earlier today. I charged from completely dead to 100% and some in about 1:45ish minutes. It took my previous 4S about 3 hours (I timed them both out of curiousity). I'm fairly certain that it does charge quicker. I'm also getting really amazing battery life.
