Wi-Fi calling is a lifesaver for all T-Mobile customers, allowing them to make calls when they are in a no network zone or in areas with spotty T-Mobile coverage. However, the Wi-Fi calling feature has turned out to be a curse in disguise for owners of the recently launched HTC One S.
Apparently, there is a power management bug connected to the Wi-Fi calling feature of the One S that drains the battery of the handset. While most Android phones already suffer from poor battery life, the One S uses Qualcomm’ newer generation S4 processor which allows the phone to easily last through a day of heavy usage. However, this Wi-Fi calling battery drain bug effectively reduces the One S battery life to a few hours, thus making lives of its owners tough.
The silver lining is that a T-Mobile representative has confirmed that the bug indeed exists and that it will be fixed in a future software update. Now, all T-Mobile One S owners need to do is make sure they always are near a power outlet with their phone’s charger and pray that T-Mobile rolls out the update ASAP.
