The HTC One X is one massive phone but it’s not perfect, like most of the high-end Android phones, its battery life is far from impressive.
The reason for low battery life is an app called NvCPLSvc.apk which is supposed to be located in system/app directory but is currently located under system/bin. But don’t worry, there’s a quick fix for this problem, one just has to move the file to its correct location and change the file’s permissions.
You can get an increase of about 10-20 percent in battery life after following the instructions given on XDA Developers’ site. Hit the source link below to improve your HTC One X’s battery life.
