Honestly I was all Gung ho and bought a spare battery and charger for my Note 2. I only ever needed it a couple times because the battery life is pretty good.
I got a Note 3 and never bothered buying the spare battery and charger. I grabbed an anker 12000mah battery which I can use to recharge all of my USB gadgets and my phone too. As others have mentioned, charging speed is fast.
I like the option of a user replaceable battery. It's great for people who buy used phones or use them for years. Personally I usually keep my phones for 1-2 years, so this doesn't matter too much to me since all of my batteries have held up ok.
