In the wake of Snowden s revelations about government snooping on users data, several companies have strengthened the security sophistication in their mobile operating systems. Google also implemented more advanced security shielding to the Android devices with its latest Android 5.0 Lollipop update. But that extra layer of protection is slowing down the devices, as revealed by AnandTech in a series of benchmark tests it performed on the Lollipop sporting devices. Weeks after Apple introduced additional layer of security on its iOS devices, Google also enforced similar encryption to guard Android-powered smartphones. The feature makes it impossible for even Google to access data stored on a user s phone, even in an event of a court order. The additional security feature comes as an optional choice with Android Lollipop. However on the Nexus 6 smartphone and Nexus 9 tablet, the feature is turned on by default and cannot be disabled.

AnandTech ran a series of benchmark tests on the Nexus 6 and found that the phone suffers a significant drop in performance when the encryption is turned on. To double check, the company asked for a special variant of Nexus 6 smartphone in which the encryption was off, and found that the phone easily outperformed its encryption-enabled counterpart. The publication then turned on the encryption on Nexus 5, and found that the Nexus 5 smartphone too was more performance efficient when the encryption was off.
It appears Google jumped the guns here and didn t completely test the encryption feature. We expect the company will soon fix this via an update, or let Nexus 6 smartphone users turn off the encryption.
