Motorola has quietly unveiled a new charging accessory that promises to deliver eight hours of battery life from a 15 minute charge. The Motorola Turbo Charger uses Qualcomm's Quick Charge 2.0 technology to pull off the feat but you'll need to meet a very specific set of criteria to realize its full potential.
As Neowin points out, the devil is in the details. For one, the battery must be substantially depleted in order to get the quickest possible charge from the Turbo Charger due to the fact that charging rates slow as charging progresses.
Furthermore, Motorola's fine print says battery life claims are based on both usage and standby time. On top of that, Motorola goes on to note that actual battery performance will vary and depends on many factors including signal strength, network configuration, age of battery, operating temperature, features selected, device settings and voice, data and other application usage patterns.
So in other words, you won't be getting anywhere near eight hours of usage time from a quick 15 minute recharge.
That said, Qualcomm's Quick Charge 2.0 is certainly a step forward for battery technology. With phones that support it (the new Moto X being one of them), you'll certainly see speedier recharge times if you're the type to run your battery down pretty low. Just don't expect the sort of jaw-dropping claims that Motorola's marketing team is pushing on a consistent basis.
