I do not work for this company, but I was getting fed up with the HTC One not having a large enough battery and itching to upgrade in the next few months because of it, but I eventually came across these guys:
iAnker
Right now I'm debating on getting one of the three (or two of the three) for my HTC One:
Astro Mini - 300mAh external battery: Anker Astro Mini 3000mAh External Battery (Black)
Astro Slim - 3200mAh external battery: Anker Astro Slim 3200mAh External Battery (Black)
Astro E5 - 15000mAh external battery: Anker Astro E5 15000mAh External Battery (Black)
I'm leaning toward getting an Astro Mini and an E5, so I can carry the Mini with me when just planning to have a day or night out in New York City, and carrying the E5 on me for school days, work days, etc. (longer days when I know I won't be home for at least 10-12 hours). However, the Slim has an advantage that it comes with a built-in charging cord, so I wouldn't need to take a long micro-USB charger with me (the one I use to charge up at home). But at the same time, if I buy the Mini and do take the micro-USB charging cord, I can clip my HTC one into my Otterbox Defender on my belt buckle/pants, and while keeping the Mini in my pocket, have the charging cord hang from the end of my HTC One into my pocket while walking, etc. So I can't exactly decide as of yet.
Let me know what you guys think.
P.S. FINALLY, I found a solution where I won't need to upgrade to something like a Butterfly S for better battery life. I really do love my HTC One!!!!
P.P.S. To address storage limitations on my Sprint 32GB Black model (I don't think Sprint offers 64GB), I'm considering using Cloud technology to download files from while on the go using 4G/LTE. That way I can listen to my seminars, music and so-forth and when I don't have enough space to watch and listen to other files, I can simply delete them from my phone and download what I want. (Tell me what you think about this as well.)
