Android 5.0 announces the full 64-bit era of arm platform

October 2014, Android 5.0 release, Android 5.0 support 64-bit CPU, Android 5.0 fully enable the art run mode, when the program is installed, pre-compiled, the new operating environment can make most applications in half the execution time. This means that applications with high CPU consumption and long running times can be completed more quickly, while general applications can be smoother, such as smoother animations and more immediate touch feedback.

And the computer from the 32-bit platform into the 64-bit platform is similar, there will be two platforms alternately bring the pain, Some applications will be incompatible, such as the Android 4.x platform running programs, on Android 5.x and above the platform can not run, but Android 5.0 to the Android ecosystem to bring speed and access to change is a disruptive revolution, Android 5.0 like a storm, crush and sweep the outdated Android 4.x system, all software authors and manufacturers are Will quickly recompile the program, To adapt to Android 5.0, this transition time is not too long, this is different from the computer platform, because the computer platform needs to consider the printer, scanners such as external device drivers, and Android does not need to consider, ROM package brush, the phone all the drivers are good, do not need to consider peripheral drivers, software updates released also quickly.

And Android 5.0 also strengthens the management of application software permissions, generally does not allow application software self-booting, which reduces the overhead of running memory ram, improve system performance.

Android 5.0 has his advantages, but there are shortcomings. Android 5.0 provides a new set of APIs for the Micro SD card read and write, the old version of the application if the program does not update, according to the traditional method, not normal access to external SD card, such as UC Browser, daily sweet, gold offline map can not directly save the directory settings external SD card, ES file Manager can not directly paste files to the SD card, because the Android 5.0 default does not open the SD card Write permission, if you want to turn on the SD card write permission, need to install the root phone after the Nextapp Sdfix software, or re-manually modified system/etc/ Permissions/platform.xml, all SD access problems will be solved after the SD card write permission is turned on.

64-bit systems and multi-core brings more power, resulting in less mobile phone standby time, mobile phone hardware CPU and screen is a big drain, in the popular Android screen, no matter how low CPU utilization, many manufacturers to take a multi-core CPU "arms race", resulting in increased power consumption, So a 2500 mah battery is basically the bottom of a large-screen phone, and 3000 mah is standard. With the large capacity battery equipped, VOOC flash charging technology has become an important selling point of mobile phones, 1.5 hours can be filled with batteries, faster than before 4 times times more than before, charging more than 10 minutes can be two hours of phone calls, very convenient.

Manufacturers have chosen the Android 5.0 platform as the flagship model, and small factories because of weak research and development capabilities, follow-up Android 5.0 is relatively lagging behind. 2015 mobile phone will be a 64-bit platform, the choice of Android 4.x mobile phone means that when you buy, the phone software hardware is obsolete.
