Flotv On Iphone Via Mophie

FloTV is a relatively new live TV device by Qualcomm. It is already revolutionizing TV on-the-go. You may recognize FloTV because itâ€™s incorporated into various cell phones such as Verizonâ€™s V CAST, or AT&Ts Mobile TV. Live television is broadcasted straight to the FloTV device or your cell phone through dedicated airwaves. This means itâ€™s not streaming and hence no buffering is involved. It also means all devices that play FloTV need a FloTV chip inside of them to receive its signal.

FloTV service and the FloTV device are really good products, and now theyâ€™re bringing Flo to the iPhone. To make this possible, FloTV will be incorporating a chip inside of Mophieâ€™s juicepack for the iPhone. So you can watch TV and charge your iPhone at the same time.

Now, not only will you get oodles more battery life out of your device, but you can view your favorite live entertainment, sports and news from the worldâ€™s top entertainment brands as well. FLO TV already boasts many of the largest broadcast & cable networks including ABC, CBS, CNBC, CNN, ESPN, Fox, MTV, NBC, TLC and many others.

â€œWe are uniting our vision of advancing mobile TV across a range of devices and platforms with Mophieâ€™s unrivaled expertise in designing intelligent cases for Apple users,â€ said Bill Stone, president of FLO TV. â€œTogether, our solution will be a true live mobile TV product available to iPhone and iPod touch users.â€

Mophie, designer of the worldâ€™s thinnest Apple-certified external battery & protective case, is equally excitedFloTV for iPhone via Mophie Battery Pack 2 about the possibilities. â€œWe are thrilled to have the opportunity to elevate our intelligent case design through this creative product collaboration and deliver the ultimate mobile television experience for iPhone users,â€ said Shawn Dougherty, vice president.

The new products will integrate Mophieâ€™s intelligent case design with a built-in FLO TV receiver that allows iPhone and iPod touch users to watch live television at the flip of a switch, while using the device as back-up battery power in-between charges.

Needless to say, a FLO TV subscription will be required in addition to the new Mophie Juice Pack, and the fruits of the new partnership arenâ€™t expected to ship until the first half of this year. There is no word on price as of yet.

What should be the expected power efficiency of using an external battery to charge an internal one?

The iPhone uses an internal Li-ion battery rated at 1400mAh. If I use an external Li-ion battery pack rated at 3400mAh, should I expect something in the range of 2.2-2.3 full charges (90-95% efficiency) or should I be happy that it does 1.5 charges (62% efficiency)?

(assuming the iphone is on airplane mode and is not in any use while charging)

Can anyone with knowledge of batteries / electronics chime in as to what to realistically expect and why?

cheers!

2 charges, if your charger electronics is good. Less than that is it is designed poorly. A good Li Ion cell can have good energy efficiency if used properly:

But the paper also shows HOW most batteries are not being used properly...
