Before shipping their latest flagship device, it makes sense that HTC would have checked and double-checked that the phone’s power management systems were up to snuff. The handset’s quad-core processor and big HD display predictably test the limits of its non-removable 1800mAh battery, but as things often go some final software tweaks were overlooked resulting in battery life that came up short of its potential. Leave it to the developer of a homebrew One X ROM to discover the discrepancy.

A misplaced APK is the culprit, and it’s been robbing users of 10 to 20 percent extra battery life. A fix has been made available for users ready to take the dive, but the process does require a bit of technical know-how. It is likely that HTC will push an update to the One X that should address the issue, so those not wishing to root their device should be able to take advantage of improve power management in the future. When that might happen is anyone’s guess.
