Sprint HTC One M8 Receives Update to 1.54.651.8, Gains Extreme Power Saving Mode

Sprint HTC One M8 Receives Update to 1.54.651.8, Gains Extreme Power Saving Mode :-

The Sprint HTC One (M8) was only released a few short weeks ago, but it has just received its first OTA update. No, it doesn’t update the device to some of those mystery Android 4.4.3 builds we’ve seen lately. Rather, it teaches the device a few new tricks.

The new firmware comes in at software version 1.54.651.8, and it features baseband version 1.05.20.0321_2. In addition to the claimed “Network acquisition enhancements,” this update brings a new Extreme Power Savings Mode. This new mode extends your battery life by “conserving CPU usage, reducing screen brightness, turning off vibration feedback, turning off data connection when screen is off, allowing only essential apps to run, and turning off pedometer.”

The new Extreme Power Savings Mode can be toggled via a status bar quick control. And as you’d expect from the name, enabling this new mode is pretty much a last resort. This is because when enabled, you’ll be prevented from doing pretty much anything with your device other than make calls, send texts and emails, check your calendar, and use the calculator.

The update is currently being delivered in the form of a staged OTA rollout. As such, not every device will receive the update in the first wave. Thankfully, XDA Recognized Contributor Rydah805 managed to pull the complete update for your sideloading pleasure. And if you would prefer to install the update without the new recovery and hboot, Senior Member eric00716 managed to separate the OTA and provide instructions on how to install it.
