How to improve performance of Nexus 6 by disabling Forced Encryption
The forced encryption feature has been claimed to be affecting the performance of Google's new Nexus smartphone powered with Android Lollipop. This feature has been present since Android 3.0 Honeycomb, but Android Lollipop is the first OS version in which it is enabled by default.
As AnandTech explains, when forced encryption is enabled, all writes to disk have the information encrypted before it is committed and likewise all reads have the information decrypted before they are returned to the process. This results in significant performance slowdown on Nexus 6.
But Motorola, the manufacturer of Nexus 6, has provided a build of Android to disable the feature. So if your Nexus 6 has become laggy, you can boost the speed of your device by disabling this forced encryption.
Recognised XDA developer, bbedward has shared a couple of stock Android Lollipop builds with no force encrypt as well as a guide explain how to disable the forced encryption on Nexus 6. Check out the following guide to disable the feature and thereby improve the performance of Nexus 6.
Before following the guide, do not forget to create a backup all data of the phone and verify that the phone should have above 80% battery.
