I am having an issue now with Sprint regarding the stock battery that came with my Photon. All of their online advertising lists the battery to be 1700 mAh. They insist this to be true. Motorola also lists the Photon to have a 1700 mAh battery. My question to all of you that wish to respond is what battery did you get when you purchased your Photon from a Sprint retail store or online thru Sprint. Mine is type HF5X with item #SNN5890A and clearly states 1650 mAh. I have read some past posts about the battery that indicated it to be 1650. Thanks in advance.
