I didn't get a great answer on the other section, so I'll try it as its own post. I recently purchased the Hyperion Samsung Galaxy S4 7500mAh Extended Battery with NEW MicroPack Technology. It is the same size as their 5200mah battery. The battery life doesn't seem to be anywhere near 7500mah. Is this "MicroPack Technology" a scam? Is there anyway I can check the actual mah of the battery? Thank you for the help.
