As new technology finds its way into flagship phones, previously cutting-edge features trickle down to mid-range and eventually low-end devices. As an economic policy the efficacy of this approach is debatable; however, it works well enough when applied to technology. With each passing year, the quality and performance of lower-cost phones improves. Not that long ago, buying a low-end phone meant a compromised user experience, the result of corner cutting to reduce cost. But today it’s possible to get a very capable phone for less than ¥1300 (about $200 USD) that does not list frustration as its primary feature. The last phone we tested at this price point was the Huawei Honor 5X, and while not perfect, it left an overall positive impression.

In this article, we’ll be examining two of its competitors: the Meizu M3 note and the Xiaomi Redmi Note 3. The similarities between these two phones extend beyond their “note” branding; they also share very similar hardware specifications and pricing, which is why we’re going to review them together. It will be interesting to see if these similarities translate to a similar user experience.

Both phones come in two basic versions: one with 2GB of RAM and 16GB of internal storage and a slightly more expensive configuration that bumps RAM to 3GB and storage to 32GB. The base configuration is pretty typical for this category, and while 2GB of RAM should be enough to provide a decent multitasking experience, having only 16GB of storage is a bit restrictive. Thankfully, both phones support microSD cards for adding storage space.

Other hardware similarities exist too, including a 5.5-inch 1080p IPS display, a 5MP front-facing camera, and a rear camera with phase detect autofocus (PDAF) and dual-tone LED flash. Both phones also support 802.11ac Wi-Fi, which is nice to see considering the Huawei Honor 5X only supports up to 802.11n and only with 2.4GHz channels, although neither includes NFC support. The Redmi Note 3 does have an FM radio and an infrared transmitter for TV remote duties, features the M3 note lacks.

The adoption rate for fingerprint sensors has been incredibly quick. It has only been a couple of years since fingerprint sensors first appeared on flagship phones, but now it’s a near ubiquitous feature from flagships down to the upper low-end. The M3 note uses a capacitive touch-based fingerprint sensor based on Meizu’s mTouch 2.1 technology that is also found in the more expensive PRO 5 and PRO 6. The Redmi Note 3 also comes with a capacitive touch-based sensor on the back of the phone. Both phones unlock quickly, but I found the M3 note’s sensor to be far more reliable, especially at handling moisture and changes in temperature. At one point I could not even get the Redmi Note 3 to register a fingerprint during the enrollment process.

One feature that helps set both of these phones apart from their peers is a large battery. While not swappable, the greater than 4000mAh battery in each phone should provide ample battery life, something we’ll quantify later in the review.

The biggest difference between these two notes is the SoC each packs inside. The MediaTek Helio P10 in the M3 note uses an octa-core CPU with a performance and power-saving cluster of four Cortex-A53 cores each for a total of eight cores. The Snapdragon 650 in the Redmi Note 3 pairs its power-saving cluster of four A53 cores with two Cortex-A72 cores, which should give it a performance advantage in most applications. There’s also two different GPUs—an ARM Mali-T860MP2 for the M3 note and a Qualcomm Adreno 510 for the Redmi Note 3—which have their own relative strengths.

Besides the different core configurations, each SoC also uses a different manufacturing process. Both are based on TSMC’s 28nm node, but the Snapdragon 650 uses 28nm HPm while the MediaTek Helio P10 uses the newer 28nm HPC+, which promises a significant reduction in leakage current relative to the HPm and HPC iterations that precede it. Implementation details, along with software optimizations and configuration settings, also play a significant role when it comes to SoC power and performance, so we’ll have to see what impact this has on battery life later in the review.

Both SoCs include an integrated baseband processor. MediaTek’s Category 6 LTE modem offers up to 300 Mb/s down and 50 Mb/s up with 2x20 MHz carrier aggregation and 64-QAM on the downlink. Qualcomm’s X8 LTE modem in the Redmi Note 3’s Snapdragon 650 SoC offers the same downlink capability but boosts uplink speed to 100 Mb/s max by adding 2x20 MHz carrier aggregation (still 16-QAM).

Both phones support Dual SIM Dual Standby (DSDS) operation, which means both SIMs are active for receiving calls or messages, but only one SIM can make a connection at a time because they share a single radio. Each phone’s card tray has two slots: The M3 note can have two NanoSIM cards or one NanoSIM and one microSD card, while the Redmi Note 3 can use one MicroSIM and one NanoSIM or one MicroSIM and one microSD card.

Frequency band support is tailored for the Asian and European markets, although neither phone supports B20 for the latter. There’s no support for North American LTE frequencies, limiting the phones to HSPA+ operation.

    Yeah, I appreciate the real life benchmarks but the software can be fixed, the hardware can not so it would be good to know where the potential of the phone lies. The measurement of the read and write speeds are very helpful in this regards but a more synthetic test would be nice, honestly I don't trust something like PCMARK at all.
  • jospoortvliet - Wednesday, July 13, 2016 - link

    I mean, "writing", "video", what are those supposed to test? Performance while writing get or playing video? Who cares, what phone has rouble with either of those tasks, a 2005 phone was fast enough...
  • John Bens - Tuesday, July 12, 2016 - link

    Nice comparison. Geekbuying actually has the M3 Note on sale at $152.99 which is a pretty good deal.
  • Geranium - Tuesday, July 12, 2016 - link

    Good phones. But as a Chinese phore there are two problems as usual
    i. UI
    ii. Software update.
    Are Chinese phone manufacturers shameless? Instead following Android design language they copy iOS design and feel good for it.
  • yoghibawono - Wednesday, July 13, 2016 - link

    they dont try to copy. They follow what the majority of their country likes. Since early 2005 I believe even HTC and Huawei dont use any app drawer. And the fact that their UI is more user friendly, vast themes, feature-rich. Even if their base is kitkat; look whose first implementing permission manager? these chinese UI. Integrated backup-restore etc etc.
  • Impulses - Thursday, July 14, 2016 - link

    Uh, pretty sure HTC has an app drawer...

    Thanks for the review Matt, much appreciated.

    Also thanks for the LTE bands support table. This is something that I've argued should be present in all reviews, and it's great to see it so prominently and clearly laid out.

    In future, can I ask Anandtech to also focus on the Android Security Level that a phone runs? I find it increasingly disturbing that OEMs are ignoring Google's monthly security patches. One review of recent security bulletin shows that each month they are fixing serious vulnerabilities, some of them being kernel-level vulnerabilities with remote exploit capabilities. In my opinion it is irresponsible, borderline unethical for a manufacturer to release a handset with known remote root exploits and then fail to patch it.

    It is one thing for an OEM to change the UI the way MIUI does, at the end of the day, these are matters of preference and taste. It is even acceptable in my view not to update the Android OS due to business/technical reasons. But not patching security vulnerabilities? That should not be acceptable. We need manufacturers to at least commit to supporting their handsets for the duration of their lifetime (whether that's two years or three years or whatever) with security patches. And we need to call out and name and shame those who don't. Frankly if websites such as AT don't do this, I don't know who will.

    Let's put it this way, if say Windows 8 or Windows 10 had a remote exploit vulnerability, and yet a laptop running the said OS didn't get this vulnerability fixed in a reasonable amount of time (for whatever reason), AT and the whole tech media would be up in arms. At the end of the day, I don't care whether it's Google's fault or the SoC vendor's fault or the OEM's fault or the carrier's fault, these are contractual details and they can sort it out between themselves. The customer pays money to an OEM (or a carrier) and the customer's contractual agreement is with them. We need to call out this situation, hold the OEM, the carrier, Google and the whole ecosystem to account. As smartphones move ever more closer to becoming general purpose computers, and they hold vast amounts of our personal information, this situation is unacceptable.

    I agree.
  • Pissedoffyouth - Wednesday, July 13, 2016 - link

    XIaomi are very good at patching security updates from what I've found
  • aryonoco - Wednesday, July 13, 2016 - link

    Great! So when you go to software info or about device (or whatever Xiaomi is calling it) you can see the Android security patch level? And they are mostly up to date? If this is true, it would make Xiaomi phones a hugely more appealing purchase in my opinion.

    And I think it would be great if a website as thorough as AT paid attention to this, and called it out.
