HTC One M9: How to Boot into Safe Mode

Safe mode is great for troubleshooting the HTC One M9 to find out if the issue you are having is caused by a 3rd party application. So let’s see how to boot into the HTC One M9 Safe Mode.

We love the plethora of applications that give us all sorts of new features, utility and customization options for our smartphone. As the saying goes, with great power comes great responsibility, and the HTC One M9 with Android is no different. So, while we can get some amazing things from our applications in the Google Play Store, if those applications are optimized or if there is simply something wrong then they can get out of hand.

This is especially prevalent after an Android update that just doesn’t play well with some applications until they are updated. One way of troubleshooting this is to uninstall all of your third-party applications.

Dozens of premium Android apps go on sale every single day. Check out the latest over at PlayStoreSales.com.

What if the issue isn’t with an application though? There’s actually a way for us to detect whether or not a 3rd party app is a culprit and that is what Safe Mode is for. Booting the HTC One M9 into safe mode will allow Android to disable all 3rd party applications without having to uninstall them. While you are in safe mode, 3rd party applications will be completely disabled and you will not be able to access them.

This seems counter-intuitive but the process goes like this. . .say you are having excessive battery drain and you suspect it is from a 3rd party application. Monitor your battery drain before booting up into safe mode and then monitor it afterward. It is natural to get a little extra battery while in safe mode but if you get 2 hours of screen on time before and then 5 hours of screen on time in safe mode then there is definitely something wrong with one of the 3rd party applications. Now that you know the cause, the next step is to find out which one is actually causing the issue.

HTC One M9 Safe Mode

  1. Press and Hold the Power Button Until You See the Power Menu
  2. Then Tap and Hold the ‘Power Off’ Option You See on Screen
  3. A ‘Reboot to Safe Mode’ Window Should Appear
  4. Next, Tap on the ‘Restart’ Option and Wait for the HTC One M9 to Reboot


You also have the option to hold the Volume Down button while the device is booting up if that is your prefered way to enter safe mode. HTC Sense has a feature that allows you to reboot into safe mode directly from the power menu though. To access this, all you have to do is press and hold the Power button until the power menu appears. This is where you would typically power down your HTC One M9.

Instead of just tapping on the Power off option, you want to tap and hold on this Power Off option. Once you do this for a few seconds a new window will appear. This is the ‘Reboot to Safe Mode’ window that you see in the picture at the very top of this tutorial. There will be two options to pick from, Cancel and Reboot. Tap on the Reboot option and then wait until your HTC One M9 reboots into safe mode.

That really is all there is to it. Again, once you are in safe mode the next step is to observe the device and find out if the issue has been resolved. Battery life isn’t the only thing that safe mode can help with. If your HTC One M9 has been performing very poorly, then maybe an application is taking up too much of your CPU/GPU/RAM resources and booting up into safe mode will help to find out if it is indeed from a 3rd party application. If the device performs like it should(nice and fluid) then the issue is likely caused by an application and your next step is to find out which one it is.
