After
confirming the upgrade to Ice Cream Sandwich for the entire 2011 range of online
Xperia interesting statements coming directly from the developer section of
Sony that clearly describe what the advantages and disadvantages in adopting the new operating system. The agonizing wait for the release of version 4.0 may in fact weaken slightly for all terminals Xperia owners who can not rely on a hardware exception.
Sony does not want to play down expectations for the update that will bring several new features on the devices, but is keen to stress that the level of stability achieved by Gingerbread is really great and not comparable to ICS, obviously still immature.
The Xperia range 2011 has an average of 1-1.4GHz CPU and 512MB of Ram , the resources that allow upgrades but also require an optimization that does not preclude good performance. Ice Cream Sandwich is bringing many new features as seen in from a new look, a UI based on Holo, Face Unlock for terminals with front camera, a book that has more contact information and much more.
This is in contrast to a system designed around devices like the Galaxy Nexus (SoC TI dual-core processor with 1Gb of Ram), hence the difficulty in adapting the Qualcomm SoC (smartphone Xperia 2011) with specifications mentioned above, which show no doubt a consuming more resources than is the case in Gingerbread:
Many App use a significantly greater amount of RAM in ICS. For example, in the web browser and is particularly evident in our measurements is shown using a 20/30 Mb in more than Gingerbread. In our studies we have also seen that the transactions in writing and reading of the SQL database gets more time in the ICS, which slows down applications.
Another important change is related to ' hardware acceleration , supported in the latest distribution from the GPU which provides an interface more smoothly with a greater demand for Ram:
Tests on our applications have shown that such settings that uses 1-2Mb of RAM more and requires more time in starting with HW acceleration. Another effect is that it can in some cases contribute to the reduction of battery backup.
To overcome these drawbacks Sony is equipping an Ice Cream Sandwich Performance Assistant , which will aim to keep an eye on the exploitation of resources and leave us to easily close the instances unnecessary, but can not do anything, for example, the acceleration hardware when playing videos that may adversely affect the autonomy compared to Gingerbread.
