Earlier this week, Android 5.1 Lollipop was finally released by Google. The official announcement gave himself lacking in detail why the many innovations that brings the update is only starting to come to light. Thus, it was expected to be screwed to energy efficiency and performance – the Nexus 6 is the first user reportedly run again liquid. The kernel developers Francisco Franco explains what the underlying.
Nexus 6: Android 5.1 Lollipop brings better performance and battery life
The list of user-relevant innovations Android 5.1 lollipop is quite long, in detail but rather unimpressive. However, it houses quite welcome changes, such as a more intuitive Tonverwaltung or enhanced Quick Settings. The apparently eliminated the “Memory Leak” also shows that Google has also created under the hood hand. A far better performance also seems to be on board – especially owners of the Nexus 6 report much faster and smoother transitions and animations.
In a post on Google+ renowned developer of Francisco Franco is known for its exquisite custom kernel, the on the ground. So the improved performance of the Nexus 6 is due to a permanent “Quad-core” mode. This means: When the screen is all four cores of the built Snapdragon 805 are active. This allows distribute the resulting work evenly across all the cores of the process scheduler, which was not necessarily the case under android 5.0. It was also filed at ART runtime and other code sections. The result is that the user takes less micro-trailer true to use.
In addition, the energy efficiency has been improved, which should lead to longer battery life. In Android 5.1, Google has provided a Qualcomm driver disabled, which is to facilitate communication between the cores. This adjusts the clock speed of both cores when a process is given. However, as the clock rate has been adjusted several times usually in the second or often raised, which leads to increased energy consumption. The even Google has obviously recognized. Since the energy saving over offers small performance gain, said driver is disabled with the Android update by default – in the custom kernel from the Franco incidentally, was for some time the case.
Bottom line, the performance seems to have become noticeably better, at the same time could be extended battery life. The update to Android 5.1 Lollipop is currently in the form of Factory Images and files for OTA Nexus 5, 6, 7 (2012) and 10 ready:
