Are you a free spirit that decided to avoid the carriers and buy an unlocked or Developer Edition of the HTC One (M8)? If so, you’ll be pleased to know that an update is now headed your way to help start your weekend on a good note.

Android Central forums user “luckydwg” has discovered than an update to software version 1.54.1540.9 is now rolling out to both the unlocked and Developer Edition versions of the HTC One (M8). The update weighs in at 117.98MB and includes enhancements to the Camera and Gallery apps as well as HTC’s Extreme Power Saving mode.

For those that don’t know, Extreme Power Saving mode can help you to extend your device’s battery life for as long as possible. When activated, features like notifications, backgrounded apps and more are disabled and the user is only given access to apps like the Dialer, SMS, Email and Calendar.

Extreme Power Saving mode sounds like a nice way to extend that last little bit of juice that your device has when you know that you’ll be away from a charger for an extended period of time. You may not be able to kill time with apps like Twiter, Facebook and the Browser, but at least you know that you’re stretching your battery out as long as you can.

Have any of you used Extreme Power Saving mode on the HTC One (M8) yet?
