Android 5.0 which is considered Lollipop version brings many changes from far and praised the success that Google do in this upgrade. However, there are some technical glitch extremely regrettable.
We can say to the initial error that the user can easily recognize after upgrading to Android 5.0 Lollipop is the machine becomes so battery power when using Wi-Fi network. While we are still waiting for a patch from Google, then again in security features accidentally quite seriously affect the performance of the equipment used.
More precisely on this issue, technology news site AnandTech has explained that all the Google wants to increase security on computers running 5.0 Lollipop to the maximum extent possible. So they quietly enable data encryption by default and this really quite serious affect on performance (best realized through the Nexus 6, Nexus 9).
In order to validate accurate information, AnandTech used a Nexus 6 and perform tests in two modes enabled and not enabled encryption enabled. The results show that, on opening enabled devices that read performance decreased to 63%, speed reduced to 50% compared with open mode enabled.
Unfortunately, the current mainstream users still can not disable encryption on Google was enabled by default on Android 5.0. Means that the customer when purchasing the device is equipped with Android 5.0 pre Lollipop can not do anything until Google announced an update to fix. For these devices the downloaded updates to Lollipop, can return to the older version of Android to ensure retention performance.
