I’ve done a couple of speed comparison tests with the HTC One S in the past, and in all the boot up portions of those tests the 1.5 GHz dual-core S4 packing HTC lost by a pretty big margin. No idea why this is, when in all other tests the Snapdragon S4 seems to outperform the competition. Anyways, HTC has a solution to this slow boot up problem (thankfully) which is called fast boot. This option lets you boot up about 4x as fast. Here’s how you enable it:

1. Go to your phone’s main Settings.
2. Go to Power.
3. Check the box next to Fast Boot to enable the feature.
