CPU Performance

This is the third Lumia smartphone that I have reviewed in the past year with the same SoC inside, so there should be no surprises as far as performance. The 1 GB of RAM is important, as some Windows Store apps are only available to devices with at least 1 GB of memory. The Snapdragon 400 MSM8926 provides plenty of power for navigating the OS, but lacks the grunt of devices like the Lumia 930 and HTC One M8. It is more forgivable in a device at this price point than the Lumia 830, even though there are other devices that may have higher specification SoCs for at or around this price point.

As this is the third device we have tested with the same SoC, there is not much to discuss about performance, but if you would like to compare this device to any other phone we have tested, you can use our online benchmark comparison database, Bench.

Quad-core Cortex A7 is not going to light the world on fire, and the Lumia 735 performs very similarly to the Lumia 630 and 830 that we have tested previously.

GPU Performance

Although the GPU powering the Lumia 735 is the same as the 630 and 830, we can now compare the Adreno 305 graphics in Windows Phone with the same GFXBench version as is available on iOS and Android. Kishonti, who are the developers of GFXBench, recently updated the Windows Phone version to 3.0.4, up from the old version 2.7. BaseMark X 1.1 is our other GPU benchmark for mobile phones, but it would not launch on this phone, and seems to have some compatibility issues with Windows Phone as I have seen this before with the Lumia 930. Performance should be the same as the Lumia 830 for BaseMark X 1.1.

Having GFXBench 3.0 now on the platform, we can now analyse the performance degradation over time.

GFXBench 3.0 Performance Degradation

There is no throttling at all on the Lumia 735, with the first and last set of runs for GFXBench at exactly the same frames per second.

Compared to the Snapdragon 800, performance is not even close, but with the pricing of the Lumia 735, and other advantages of the Snapdragon 400 such as battery life, the performance is not too bad for basic apps. The Lumia 930 can open apps quite a bit quicker, but with Windows Phone, animations are always smooth and fluid.

    Great article as always! I decided to finally create an account just to comment on this one. I have this phone, bought it 3 when it barely came out to replace my old and ageing trustworthy Nokia 5800. I tried several phones before making the decision to buy this one, several androids from several brands, i even glimpsed at the iphone (but that one was is too expensive for my poor pockets), and then i tried windows phone on a low end device. After seeing how fast it was, i decided to search for the lumia phones. Seeing this one had just came out 2 weeks ago back then, i decided to check for the pricing, and it was with a great discount: Unlocked for 189€ (it was, and still is, 249€ in most stores), so I decided "what tha hell, let's jump into the windows phone and see what's it about.", as i pretty much already knew well what android and ios could offer me, and kept hearing how "bad and lacking windows phone was".

    God damn it's great!

    Phone runs super smooth, the hand feel is just right, screen has incredible colous, love the blacks, the entire system just pieces together incredibly well, and the so called "app lacking" problems are not nearly as close as people say it is: actually so far i haven't felt the need for any app that's lacking, even multilayer games a few of my collogues have and want me to play with them, i have them available on the store.

    I can't believe i went for 6 years with Nokia 5800 thinking not a single phone could replace it anytime soon, and it seems this one was a heck of a deal for the price i got it (it was back in November, it had just arrived to my country it seemed).

    Battery lasts for me 2 full days, and i do use the phone quite a lot during my day. Only thing i found sad to discover this one didn't have is the glance screen, but it's not that much of a big deal breaker.

    A few stores have knocked the price down to 199.90€ (unlocked, it's at 168€ in Vodafone right now, locked of course) recently, so this phone should start being a hit, IF people stop being idiots saying Windows Phone isn't any good and actually try it out.

    So far I don't have any problems with it, except for one: My wallet is screaming right now, as i just bought a second one to offer my sister for her 38th birthday haha. Got the Orange one for her as well, mine's the dark grey one.

    Slap on it a SD card and you wont have any storage issues. 16GB fast mSD cards run so cheap this days (8€), it's a steal really. I got a 64GB card for mine to store all the things and more though :)

    Just to piggyback on your comment, before I bought my first smartphone (iphone 4) in 2010 I had the Nokia 7250i since 2004. I too went with the older nokia phone for 6 years. I bought a cheap lumia 525 and I'm seriously thinking of getting a high end windows phone once my iphone 6 plus dies (probably another 4 yrs).

    The Glance Screen is available as a download from the app-store. See: http://www.windowsphone.com/en-us/store/app/glance...
  • AlluringRaja - Friday, February 13, 2015 - link

    Yes I saw that but I think glance screen is not available to download for Lumia 520. There is no download button.

    Why you never test audio output quality from jack? Is no one listening to the music anymore?
  • cbf - Wednesday, February 4, 2015 - link

    Well, I guess this is good review for users outside the US. But why does Microsoft give you a phone to review that's not really available for sale here, or support the common US LTE bands?

    Thanks for the review Brett, I have bought the dual sim Lumia 730 for $200 factory unlocked version, so its a very good deal when compared to the $375 Lumia 830 in my country. I was sick of carrying two phones and badly needed a dual sim phone and the Lumia 730 announcement got my interest.

    I don't like huge phones, so the 4.7inch screen is perfect for me, the OLED screen is of good quality, windows phone has the best implementation of MicroSD cards and thus storage is a non-issue, the phone design is nice with light weight and comfortable curves, got the Matte finish dark grey colour as i prefer matte finish and dark colours. The camera quality is actually good and can be bettered only by flagship phones, no other $200 phone can compete with Lumia 730 in this department !!

    Now, looking forward to Windows 10 technical preview, i know that the final W10 launch will be in Fall-2015 but its nice of Microsoft to allow direct OS updates via technical preview or preview for developers app.

    The charge time is incredibly long given its battery capacity! Is it possible to charge the Lumia 735 using beefier chargers like 5V/1A or 5V/2A so as to reduce charge time?
  • BMNify - Saturday, February 7, 2015 - link

    Definitely, you can charge 730/735 with the beefier chargers, i charge my Lumia 730 Dual Sim with a 2A charger and i haven't timed it but its much much faster than the 0.75A charger i got in the box.
