A thorough verification of performance improvement by updating to Android 5.0 Lollipop

Android 5.0 (Lollipop)Has been able to update sequentially from the Nexus series, and although the pace is slow, the corresponding model has gradually increased. Whether or not processing speed and battery possessions are improved with Google's Android 5.0, a newly improved version of Google,TechSpotIt is verifying.

Android 5.0 Lollipop Tested: Performance and Battery Life - TechSpot

Android 5.0 adopted "ART (Android Runtime)" of the runtime (virtual machine) which was experimentally introduced as a developer test on Android 4.4 (KitKat) by default. It is expected that the application execution speed will be increased compared with the conventional Dalvik. Also,"Project Volta"Job Scheduler" API for new battery management that was announced as it was seen as improving battery possession. So TechSpot verified, "Is it really improving the performance as originally announced?"

Updates to Andoroid 5.0 (Lollipop) from previous versions of Android OS are being advanced sequentially for each model, but its pace is extremely slow compared to iOS and Windows Phone, which is customary in Android OS. In this verification experiment TechSpot excluded Google's Nexus series of models that have already started updating to Android 5.0, Motolora'sMoto X (2014),Moto G (2014), Samsung'sGalaxy S5, LGG3We have tested after initializing after updating 4 models of OTA and official ROM base.


◆ CPU Performance
According to Google, "With full migration to the new runtime ART, there should be performance upgrades in benchmark software and 32 bit environment on Android 5.0". So, the results of various benchmark tests using 4 models are as follows. The data shows that the higher the numerical value except Kraken 1.1 application, the higher the performance.

·Peacekeeper
In Peacekeeper the scores are decreasing with Moto X and G3.


·Octane 2.0
Moto X is decreasing slightly, but the range of error.


·Kraken 1.1
Attention to high performance as the number is smaller.


·Vellamo 3.0
It is conspicuous that the score of G3 is greatly reduced.


·Basemark OS II
The score of Android 4.4 of G3 is remarkably low because correspondence of the application has not been completed, and Android 5.0 is a formally corresponded numerical value.


·PCMark for Android
In PCMark for Android which adopts the test environment which most faithfully reproduces "general usage", the performance of all models improved.


According to TechSpot, although updating to Android 5.0 requires the application's initial launch time to take longer than Android 4.4, it generally feels crisp and faster than before. And the result of PCMark for Android which is a benchmark application assuming usual usage method is the result as impressive, and Google's view that realizing performance improvement even with the same hardware configuration by updating to Android 5.0 It is street.

As for the fact that the numerical value of G3 is decreasing in some tests, there is a possibility that the program that reduces the CPU clock at the time of fever may be the cause, and the result itself seems to be valid.

◆ Battery operating time
Next, test of battery-driven time to see if the power of Job Scheduler is demonstrated is like this. All scores indicate that the higher the performance, the higher.

· Video playback
This is the result when viewing the 720p movie in 75% luminance and in the in-flight mode with Wi-Fi turned off.


· Internet browsing on Wi-Fi
Result of browsing TechSpot's article on Wi-Fi connection with 50% brightness.


· Internet browsing in LTE
Also Internet browsing on LTE line. It is almost the same trend as Wi-Fi.


· PCMark benchmark
Reproducing general usage PCMark Benchmark execution time battery run time, Android 5.0 performance is improved in all models.


According to TechSpot, it is expected as expected that the power of the new API / Job Scheduler will not be demonstrated because CPU processing accounts for a small percentage of the load on the terminal in movie viewing and net browsing applications. However, since PCMark's bench test showed an average performance improvement of 20%, performance improvement can be expected with general usage method, Android 5.0 seems to have improved battery possession.

As for performance degradation in Moto G and G3, TechSpot points out that there is a possibility that a malfunction related to modem software is expected, so there is a possibility that it can be improved by official OTA update.

◆ GPU Performance
Benchmark results on graphic performance are also released.

·Basemark X(High Quality)


· Basemark X (Medium Quality)


·3D Mark(Ice Storm Unlimited)


·GFXBench(T-Rex HD Benchmark Onscreen)


· GFX Bench (Manhattan Benchmark Offscreen)


According to TechSpot ART is not compatible with 3D rendering It is assumed that benchmark performance has not improved at the present time. The performance deterioration in Moto X and G 3 is said to be within the error range.
