HTC One X gets unofficial power management fix, boosts battery life 10 to 20 percent

Somewhere along mike1986's development of Android Revolution HD, a custom ROM for the HTC One X, he found that something amiss with the smartphone's stock system -- its Tegra 3 power management software didn't function properly. According to the developer, an app known as NvCPLSvc.apk was misplaced in the /system/bin folder, rather than its proper destination of /system/app. Along with the custom ROM, mike1986 has released the fix as a separate bundle, which is detailed in the source below. To apply the patch, users must push the new APK to their handset via ADB, and then alter the file's permissions. Unless you're seriously hindered by your phone's battery life, however, it seems safe to wait for an official update from HTC. On the upside, users report an battery life increase in the neighborhood of 10 to 20 percent once with the fix in place, and we can only hope that all users will soon benefit from similar gains.
