Verified Purchase(What is this?)
This review is from: Anker® 2600mAh Li-ion Battery for Samsung Galaxy S4, I9500, I9505, I9506 (Not for Galaxy S4 Active), with NFC/Google Wallet Compatibility [18-Month Warranty] (Wireless Phone Accessory)
I've run out of battery life so many times on the standard battery - usually as I'm leaving a pub in the middle of a place I've never been to before. After relying on blind luck and chance enough times to get me home I decided to take fate into my own hands and bought this. I'd never go back to a 1 battery setup again.
