At 19:00 on January 4, 2016, the official forum of Hammer Technology issued a statement on the top of the post Smartisan T1 The optimization of such high configuration mobile phones is not obvious (the performance of nut mobile phones with relatively low-end chips is significantly improved), so the Smartisan T1 will continue to maintain and upgrade the Smartisan OS based on Android 4.4 until May 19, 2017.

In other words, all current Smartisan T1 users will never get the official Android 5.0/5.1 system, and after May 19, 2017, the official will stop the system maintenance of Smartisan T1.

Why is it that nut mobile phones are greatly improved, but the optimization of Smartisan T1 is not obvious?

Compared with Android 4.4, Android 5.1 has the biggest optimization improvement of supporting 64 bit applications Enable AArch64 feature of 64 bit SoC The system defaults to the global ART mode. In terms of parameters, the SoC equipped with Smartisan T1 is Snapdragon 801, which is a 32-bit processor. Although the nut phone is a new SoC Snapdragon 615, there is still a gap in its performance compared with Snapdragon 801. The most important key is that Snapdragon 615 is a SoC that supports 64 bits, and Snapdragon 801 is 32-bit.

That is to say, even if it is upgraded to Android 5.1, since the Snapdragon 801 is only 32 bits, it does not support 64 bit applications and systems, while the Snapdragon 615 of the nut phone supports it.

However, there is a problem here. Even though 64 bit systems are not supported, the global ART mode of Android 5.1 has system optimization compared with the Smartisan T1 of Android 4.4, which cannot enable ART.

How much does Android 5.1 improve nut phones?

Although we all know that Android 5.1 supports 64 bit applications, and Enable AArch64 feature of 64 bit SoC However, it is a pity that we upgraded our nut phone to Android 5.1 and found that it does not support 64 bit, but its Android 5.1 is 32-bit. That is to say, the system optimization of Nuts mobile phone upgrading to Android 5.1 mainly comes from the global ART mode, which is similar to the optimization effect of Smartisan T1 upgrading to Android 5.1. In other words, since Nuts mobile phone Android 5.1 is 32-bit, why does Smartisan T1 not get 32-bit Android 5.1 push? However, we found that Android 5.1 of Smartisan T2 supports 64 bit.

Indeed, as the Hammer official said, Android 5.1 has not significantly improved the performance of high configuration mobile phones such as Smartisan T1 (it has significantly improved the performance of low-end nut mobile phones with chips), but the Hammer official did not figure out the gap in this performance improvement, and the official gave the "Smartisan T1 The argument that Android 5.1 cannot be upgraded "because the performance improvement is not as good as that of nut phones is not tenable, because the currently launched 32-bit Android 5.1 has almost the same system optimization and improvement for nut phones and Smartisan T1.
