Moto X: ART vs Dalvik

[A895]

I have now been running ART on my Moto X for the past 2-3 weeks straight. I thought I would post my findings below:

Performance:
I think performance was very good, I could consistently juggle multiple apps all the time. But, there is a caveat; web browsing sucks. I tried multiple web browsers and finally I got consistently decent performance on Chrome Beta. Regular Chrome was atrocious. Other than that apps opened quickly and without delay, and in app performance (outside of web browsing) was fantastic. Web browsing was killing me though.

Battery Life:
Battery life as many Moto X owners know is always been a high point. Before ART my battery lasted all day consistently and I had a hard time killing it in one day, honestly. With ART well..... it`s hard to say exactly but, its all day battery life for sure. But, I`m not seeing anything awesome about it. If anything I say its a placebo affect. It may appear to be longer but, I cant tell for sure. I just switched to Dalvik today so if there is any difference I will update later on.

Odds and Ends:

• I noticed that I get a Google Services has stopped at least twice a day. I`m thinking it has to do with not being compatible with ART. I will keep an eye out for it today.
• I noticed instantly upon switching to Dalvik, that opening and closing apps are a little slower. Take that how you will.
• Again with web browsing, upon switching to Dalvik web browsing was so much more smoother on Chrome Beta it was like a breath of fresh air how much smoother it was.

NOTE: Any other findings I have I will post tonight after running Dalvik for the day.

Didn't 4.4.2 address some of the issues you are having?

I use Naked Browser, no issue with web browsing speed on ART.

So funny that I started a thread on this the other day...

I did see the Google services disconnect as well when I restarted the phone while on art.

I think battery is better on Davlik honestly.

I switched back to Davlik this weekend. I dont really think the apps take that much longer to open and plus I'd rather have better battery life.

Naked Browser was alright but even then I didn't enjoy it that much.

Its not that much longer but, when you are multitasking a couple of milliseconds of a difference. Any average person wouldn't notice.

Re: Moto X ART vs Dalvik

There is nothing on my phone that I can't wait a few milliseconds for. Now if it was a difference of multiple seconds... That would be an issue. Just had to change over my wife's Droid 4 to her new moto x.... That was painful to me... Lol! That Droid 4 was SLLOOOOWW! Compared to the moto x.

It wasn't the fact that its slow. God no. My Moto X is super fast. Its just the fact there is slight decrease in speed between multitasking on Dalvik compared to ART.

UPDATE 1:
Switched back to ART. Dalvik ran fine except for the fact Android OS ate the hell out of my battery today. The moment I switched to ART battery power drain noticeably slowed down.

Re: Moto X ART vs Dalvik

I thought the point of ART was that apps were no longer being compiled when launched but were compiled beforehand. Therefore, the idea was that they would launch faster and with lesser CPU processing power. I ran ART for a while and can't say I noticed any difference at all. The only reason I switched back to Dalvik was due to a problem with uploading pics on Facebook. Otherwise, I didn't have any issues with ART.

I switched art to see what it was all about and I love it so far. All of my apps work and everything is just so much smoother on my unlocked Moto x.

The problem uploading pictures to Facebook using ART has been corrected. I switched back to Dalvik for the same reason but just gave ART another try today and was able to upload a picture to Facebook without any problem.

With ART I definitely noticed apps open quicker and behave a little better.

Re: Moto X ART vs Dalvik

Switched back to Dalvik for the second time last night. Although it now works for uploading pictures to FB, I found it didn't work for at least 2 other apps I have on my phone, eBay and Photobucket. It did seem to be much quicker on ART than the first time I tried it, but will wait some more until it's optimized and works with all apps that I use.

Yeah that's very weird. Android OS has to eat up my battery and data.

Re: Moto X ART vs Dalvik

I was in building today that has horrible reception too but I noticed it after u posted ur findings yesterday. I was going to give it a few more days but after seeing that I switched back to Art. I think when I lose battery life... It's my own doing with a game or whatever. If I don't play a game this thing lasts and lasts.

Re: Moto X ART vs Dalvik

The performance differences between Dalvik and ART are not humanly detectable. Its nearly impossible to have other computers detect it. The reason ART was even created was because Dalvik is not a Google owned IP and they are very limited in modifying it to suit Android perfectly. So yeah it might not be better than Dalvik yet but it will be. It is usable at this point just for testing/development not to improve performance intentionally.
