GPU Performance

While CPU performance has improved significantly in low-end and mid-range smartphones, the same can't be said of GPU performance. Adreno 306 is really just a variant of Adreno 305, which we have covered time and time again in reviews of Snapdragon 400 devices. I already discussed in my Moto E review that I'm not happy with the graphics performance in Snapdragon 410 and with the GPU configuration in the Moto G being exactly the same there won't be any significant changes to graphics performance.

3DMark 1.2 Unlimited - Physics

3DMark 1.2 Unlimited - Overall

Due to the way 3DMark calculates its overall score, it's not possible for a device to pull ahead based on the score of one test being substantially higher than the other. Because of this, the Moto G's improvement in the physics test doesn't lead to it coming on top overall due to its slightly lower graphics score. I would just attribute the lower graphics test score to testing variance, and so in reality the Moto G will be slightly faster than the Moto E or older Moto G in any physics heavy games.

BaseMark X 1.1 - Overall (High Quality)

Driver bugs had previously prevented me from running BaseMark X on Snapdragon 410 devices. This appears to have been resolved, as the test runs and completes on the Moto G. There's not much to be said about the scores, which are at the bottom of the charts in every single test.

GFXBench 3.0 T-Rex HD (Onscreen)

GFXBench 3.0 Manhattan (Onscreen)

As expected, performance in GFXBench on the new Moto G is essentially identical to that of other Adreno 305/306 devices. Unfortunately they all share a space at the very bottom of each chart, and end up being between 1/3 and 1/2 the speed of the Adreno 405 GPU in Snapdragon 615.

When I reviewed the Moto E I gave the GPU performance a pass because the phone sold for $100-130. With the Moto G priced as high as $219 for the high end model, I have to say that $30 more gets you the Huawei P8 Lite which uses Snapdragon 615 and Adreno 405 which is substantially faster. There's not much Motorola could do about this apart from using a completely different SoC, but obviously that wasn't a possibility when building a device that does start at $179 even if it scales up to $219. I just hope that we see some improvement in GPU performance on devices at this price point in the near future.

NAND Performance

Flash memory performance can often be an invisible performance bottleneck when applications are running in the background, writing files, or performing updates. Low-end and mid-range devices often suffer from very poor NAND performance which can cause stuttering or slowness whenever there's heavy I/O activity occurring.

Internal NAND - Random Read

Internal NAND - Random Write

Random read speeds on the Moto G are much faster than the Moto E or the Huawei P8 Lite. They're certainly not the fastest on record, but they're at the point where I wouldn't worry about them causing performance problems in most circumstances. The random write speed is a very curious case, with it being faster than every other device on record. There doesn't appear to be any problem with the testing, and it seems that the Moto G's NAND simply has relatively fast random write speeds.

Internal NAND - Sequential Read

Internal NAND - Sequential Write

Sequential read speeds on the Moto G are faster than other mid range phones, but not as fast as the Zenfone 2 or flagship Android devices. Sequential writes sit right in the middle of the chart and are around the same speed as the NAND in LG's flagship devices. Whether it's random or sequential access I don't expect users will encounter any performance issues on the Moto G caused by poor NAND performance.

    Can you measure minimum brightness? I like to use my phone at night and an idea of how dim these phone screens can get would be helpful.

    I wish the new Moto G supported VoLTE and T-Mobile's band 12. The only non-flagship, less expensive phones T-Mobile does support for this functionality are not very good values relative to all the phones without it, like the new Moto G, ZenFone 2, Idol 3, etc. The $100 T-Mobile Lumia 640 does support VoLTE and LTE band 12 (and Wi-Fi Calling 2.0), but the apps I might want to run aren't available for Windows phone.

    Otherwise, on T-Mobile, as LTE band 12 is being rolled out now, non-LTE band 12 phones could become obsolete much sooner than phones with band 12, because the band 12 signal penetrates buildings better and travels farther in rural areas, AOTBE.

    Even the iPhone 6/6+ doesn't support T-Mobile's LTE band 12. However, the T-Mobile branded Nexus 6 does (with VoLTE, Wi-Fi Calling 2.0, etc.). Hopefully the new, smaller, less expensive Nexus 5 will have those features and be sold through T-Mobile like the Nexus 6.

    Yeah I run a totally stock Nexus 4 and I can go two days easy on a charge if I don't use it like a Gameboy. This is on a nearly three year old battery.

    No battery gimmicks, just make sure I only keep the apps on the phone that I actually use.

    Running my new moto g 3gen. Have the 2gig model. So far good little phone. At the price a great phone.

    Phones like this are exactly the reason why Samsung is failing so hard to sell S6s. Far better utility, software and cheaper prices while only sacrificing marginal real world camera/SoC performance and display quality.

    Not a word on software? Is this running vanilla android? Are all motorolas still running vanilla android? Are they getting updates?
  • Brandon Chester - Friday, August 21, 2015 - link

    At this point the software situation is essentially the same on all Motorola devices so you can check out my comments in the recent Moto E 2015 review for the small changes that Motorola makes to "stock" Google Android.

    Charging time seems wrong. The Moto G 2015 that I have charges from 0 to 100% in 2.5hrs with the charger that came along with the phone
  • MarkHunt - Thursday, September 24, 2015 - link

    Stay away from Motorola if you want fast Android OS updates- it's a myth that they provide them quickly. When they do get round to it, they infuriatingly do it country by country over a period of months. Best get a Nexus phone.

    I know it's a bit too late but just a bit of thought on the newly launched Moto G Turbo with Snapdragon 615 A53 1.5GHz + A53 1GHz and all the rest specs matching Moto G 2015. I think this should mean a further great battery life with much enhanced graphics performance. I especially want your opinion Brandon and others' remarks are also welcome.
