What Extreme Power Saving Mode is and how it can help you make the most of your HTC One M8’s battery life

The HTC One M8 may have more than average battery life for a smartphone of its size, but that doesn’t mean we won’t run into situations where we can’t get to a charger and we’re running low on battery life. For that, there’s Extreme Power Saving Mode. This feature can help you conserve as much battery life as possible, hopefully until you can get to a charger again.
