WiFi Performance

Moving on to WiFi performance we address one of the most critical faults of the P8: Lack of 5GHz WiFi. There were already some raised eyebrows during the official announcement where we couldn't find any mention of 802.11ac in any of the spec sheets, and indeed, the device comes without support for the higher frequency bands.

This raises some big questions about Huawei's choice of RF back-end and what exactly is going on there. Connectivity itself is provided by a Broadcom BCM4334, which is quite an ancient chipset by today's standards, as we first saw its introduction in 2012. Broadcom advertises max PHY rates of up to 150Mbps and upper layer rates of up to 90Mbps - and 5GHz is definitely listed as one of its capabilities. This is the same chip used in the Honor 6 and Mate 7, which did have 5GHz capability. In the end only Huawei knows what kind of decision-making process warranted such a significant omission of an every-day important feature.

WiFi Performance - UDP

The Honor 6 and Mate 7's WiFi performances still leave a bitter taste due to their bad WiFi performances, and the P8 does little to sweeten the deal. Yet again we see atrocious numbers from the affected devices. A especially very weird characteristic that can only be found on the Huawei devices is that we see discrepancies between downstream and upstream transfer speeds, as transfers in the downstream direction are consistently faster than upstream data transfers.

I suspected there was some software reason as to why this happened back when reviewing the H6 and MT7, but couldn't confirm it as Huawei hadn't released the source code for the devices yet. Since then, they did manage to comply to GPL and make the kernel sources available.

While searching through Broadcom's DHD driver to see what changes Huawei/HiSilicon have made, one notable change that I stumbled upon, although not related to the bad WiFi speeds, was their network traffic DVFS mechanism. This has nowdays become quite of a standard in modern devices as vendors try to improve latency and response-time of devices. Most notably Samsung has a very robust framework that boosts CPU and memory frequency when detecting spikes in network and NAND throughput (Among others). It's interesting to see how these quality-of-service mechanism gain popularity among vendors.

In the end the software assumption just didn't work out. Simply gripping the phone in-hand will reduce the transfer speeds by a third, clearly pointing out that this is an antenna/RF issue and not a software bottleneck or bandwidth throttling.

GNS Performance

I wasn't able to fully determine what silicon provides the GPS functionality for the P8, but I suspect it is the Kirin SoC and its integrated Balong modem have a play in it.

No matter who provides the chip solution, the end-result is what counts. Here the P8 performs very well by being able to capture a large number of satellites at high strength. Cold lock-on without AGPS assistance took 39 seconds, while with pre-cached location data the P8 was able to have a location fix in under 3 seconds.

NAND Performance

NAND performance was again one of the weak spots of previous Huawei devices, with the H6 and MT7 using quite old eMMC units that were also used back in the Galaxy S3. The P8 remedies this by using a faster SanDisk SDW16G unit.

Internal NAND - Sequential Read

Internal NAND - Sequential Write

Internal NAND - Random Read

Internal NAND - Random Write

While the new eMMC doesn't break any records, it's now among the "average" performing devices out there, as opposed to the horrendous performances of the Mate 7 and Honor 6.

    It's probably more useful than an iPhone for people who travel a lot and occasionally go off the grid, and thus need the device to still work as a GPS, camera, miniature computer, etc, while drawing all data from fast, convenient local storage...

    - It has a MicroSDXC slot, so it can take the new 200GB MicroSD storage cards; and

    - It has dual SIMS.

    Unfortunately, it lacks a user removable battery, so it is still inferior in that regard to each of the phones and phablets that I already have. But, in general, I like what they are doing.

    Something that other nationals can tend to forget is that China has a lot of wealthy people (far more than the US or possibly even Europe). Even though these elite Chinese are wealthy, many of them are shrewd spenders. They want value for their high-end spend. So there is a lot of pressure on Chinese vendors to produce high-end devices that include every possible feature.

    So just like Japanese enthusiasts used to get certain stereos and cameras that America only dreamed of, the Chinese are demanding that the manufacturers provide more fully functional high-end phones that can do everything... including the things that the iPhone cannot do.

    That said, the iPhone is making headway in China too...

    ... but just like in the US, it's for all the wrong reasons. Namely, it's a jewelry piece that holds sway as a status symbol amongst the more vacuous of minds. Owning one supposedly elevates your perceived social status - much in the way that owning a ludicrously expensive sports car or ultra-luxury car does the same (think Rolls-Royce, Bentley, etc.).

    Sociologists and psychologists have hypothesized that such objects are attractive to both the buyers who display them publicly and to those who view them, particularly the opposite sex.
    People who buy these objects are subliminally advertising to potential mates that they have excess money that (under the proper circumstances) can in the future be re-directed to caring and tending for children and non-working spouses.

    The attraction effect is generally stronger if the object is purchased and displayed by a male, because many societies still expect the male to bear the larger burden of providing financial resources. This is especially the case while the female is pregnant and in the early years of caring for children that aren't yet school aged.

    The larger the excess spend over the practical value, the higher the perception of excess earning capacity. That's why we sometimes see phones sold with precious jewels encrusting them. Apple is just doing the same thing on a lower level... right out of the box. Charging more than the inherent underlying value.

    So it's rather refreshing to see the Chinese manufacturers taking a different approach.

    And it is especially refreshing to see the Chinese doing this in light of the fact that Samsung vacated the market as an Apple competitor and have now lowered themselves to merely matching Apple's product features. Without the Chinese, the Apple-Samsung twins (newly conjoined) don't really have any competition. The Chinese upping their game changes things.

    Of course Apple can play this game too if they want. They simply need to offer more than 264GB of storage. The P8's 64GB of onboard NAND storage combined with the new SanDisk 200GB Micro-SDXC storage card will now set a very high bar that Apple needs to try to hurdle over (if Apple wants to be taken seriously with regard to storage).

    I'm thinking that if Apple offers its next phone with 512GB of storage then that would safely secure the storage crown for them (remember, Samsung used to regularly double Apple's storage by simply adding a Micro-SD slot, but Samsung has now given up on competing).

    Then Apple would need to add Dual-SIM slots to improve connectivity and travelability. It may come as a surprise to the uninformed that the newly wealthy Chinese (like many other nationals) are joining the tourist-corps. They are world travelers and they want their phones to work anywhere that they are likely to travel. Having Dual-SIMs makes it both convenient and affordable (roaming data charges are still the bane of the planet, even for wealthy Chinese).

    I would also argue that to be better than what I've personally already got (and most Chinese, other Asians, Middle-Easterners, Africans, and Europeans already have), Apple would need to offer user removable back covers and batteries. Nothing says "I can handle a thirty hour multiple segment, multi-modal (air, sea, and land) journey" than a couple of lightweight fully-charged spare batteries. No awkward cables... just plop in and play on like nobody's watching.

    So the Chinese phones are Apple clones? Nahh, this is just the Chinese practicing for the end-game. They want to do what Samsung used to regularly do to Apple: offer the consumer more for less... and the Chinese have just proven that they can win the storage crown. So who is to say they won't eventually win the various other races to provide the best-of-the-best on the other features? All it requires is Apple-Sung to remain lazy… which is something they have lately proven to be very adept at.

    I signed up just to be able to thank you for this comment. You brilliantly summarised everything that's wrong with the current "leaders" of the mobile phone industry. I've been a Samsung user for years after being disappointed by the iPhone 3G then HTC in general but now when my contract expires for my Note 3 I am leaving for a Chinese brand, I want to support a company that hasn't given up trying.

    Always surprises me how people in these blogs write about what Apple "should do", but for what? To be even more successful? What are their credentials?
    Of course, anyone can say what they like or dislike. But the implicit assumption in most of these comments is "I know better", which is, at the least, presumptuous
  • Rod_Serling_Lives - Friday, June 5, 2015 - link

    Well said. Apple already dominates with only a handful of devices and I don't know if they could be in a better position than they are currently.
  • nathanddrews - Friday, June 5, 2015 - link

    Personally, I don't like anything about Apple except the build quality of most of its products and its stock price. Cha-ching! I don't buy Apple products or use Apple software, but I'm happy the corporation is so successful. Deep down inside, I find myself horribly judging and mocking consumers of Apple products, but then I just have to remind myself not to feel bad about it. They're already dead inside.

    ;-)

    I think it's Tall Poppy syndrome... even ignoring everything else Apple has pioneered over the years and just looking at the Apple Watch - first gen of hardware and software, and it's amazingly smooth and will have years of support and development. With the hardware makers for Android, they are all dropping support for SD cards and removable batteries, except LG (?), but no one seems to talk about it when it happens. I think people start making 'I know better' statements because they don't check history.

    I agree with many of the things you said, but your theory about iphone as a status symbol is incomplete. I mean, according to what you said it seems that most buyers should be single men, and I have seen as many women as men with iPhone in Shanghai (maybe more, as female tend to follow fashion very strongly, and most cannot choose a phone based on "tech" or "features").
    Also, many married couples and middle aged and old persons use iPhone. Even students have them.
    It always strikes me, because in China iPhone's price is quite higher than the average salary in the first tier cities. Imagine if an iPhone cost 2000 USD in the US. Nobody would buy it, but in china they do.
    I guess mostly because the "status symbol" thing, but not to impress potential sexual partners, just to say "hey, look, I am NOT POOR", even if you are and cannot afford a health insurance and use recycled oil for cooking. After the communist times, Chinese socity has gone to the other extreme. Now being poor is not just pityful, it is shameful. No matter how, even if you have to sell tainted milk to babies or steal from your fellow citizens with lies, you MUST become rich. Of course, most cannot, so that's why they think having a "symbol" is better than nothing. "Appearence" is king nowadays in China, not "substance". I guess they need 20 more years to find a balance. Too many changes, too fast.

    You wish the iphone had a sane design like this instead of their roadkill look.

    If Apple had cloned this device, it would have been better. Instead of the huge bezels it would have had a much more usable form factor.
