We just showed you one modification users can make to their HTC One X handsets in order to eke a little extra performance out of their cameras. While that sounded like good news for users really obsessed with image quality (and especially those who plan on shooting a lot of 1080p video), we just heard about another One X mod that’s arguably a whole lot more useful; making a few simple adjustments to your phone’s software is supposedly capable of delivering a 10-20% improvement in battery life.
After poking through the HTC One X’s file system, one developer noticed something was amiss. The phone was apparently supposed to be using a certain package for power management, but it seems like it was installed in the wrong directory, and as a result isn’t functional on stock handsets.
Enabling the software is relatively straightforward, transferring a new copy of the NvCPLSvc app to the phone. Presumably, HTC will be making the correction itself in the next system software update for the One X (assuming it wasn’t disabled intentionally), if you don’t feel comfortable making the change yourself. If you are up for it, on the other hand, check out the details in the source link below.
