If you recently purchased an HTC One S for T-Mobile, congratulations - you've got one of the best Android phones available in the US at the moment. But as is usually the case with high-profile phone releases, there's at least one fly in the ointment. T-Mobile's unique WiFi calling service is included on their version of the One S to save picky customers from using up their calling minutes. But it looks like this feature is draining the battery unusually fast, and at least some T-Mobile customers must have already complained.
Not to worry, though: Magenta has a fool-proof solution to keep your One S from losing power: charge it while you're making Wifi calls. Yes, really. For a more permanent solution, the carrier says that the problem will be addressed in a future software update. Which, you know, helps. In the meantime, calls via Skype and similar VOIP services seem to work fine, though the charges therein aren't included in your T-Mobile subscription.
The One S normally gets pretty solid battery life, thanks to a slightly larger than average 1650mAh battery and the solid power management properties of Qualcomm's Snapdragon S4. I'm no expert, but if there's an issue here's it's probably got something to do with the wireless chipset opening up more bandwidth (and thus battery drain) than is strictly necessary for WiFi calling. It could also be something unique to T-Mobile's app, perhaps communicating poorly with the One S hardware, Ice Cream Sandwich or Sense 4.0, none of which appeared on T-Mobile before the One S. We'll be eagerly waiting more specifics from either T-Mobile or HTC.
