The Mi 4s was a surprise inclusion during the Xiaomi Mi 5 launch event a few weeks back. Since Xiaomi planned to make the Mi 5 an international flagship all along, they perhaps wanted to have a China-only device so the home market still felt âlooked afterâ. And thus, the Mi 4s is a China-only device that you need to import yourself if you fancy one.
Anyway, Iâve spent a good couple of weeks with the Mi 4s so letâs talk about whether it is worth importing one⊠in the Xiaomi Mi 4s review!

Xiaomi Mi 4s Review: Design & Build
The Mi 4s has quite a characteristic design. In the sense that it wonât get lost in the array of almost identical-looking phones that are being churned out.
That said, youâre either going to love or hate the Mi 4s⊠since the design is so characteristic and typical. In my opinion, the Mi 4s was designed to fit the Chinese market and only the Chinese market, which often has unique demands.
The âgoldâ isnât quite rose gold (the kind of gold with a pinkish hue) but more like light brown. The metallic edges of the phone donât feel as âmetalâ (as say, the Mi 4) and lack the cold metal feel, but they do make the phone really easy and comfortable to grip.
The device follows a very symmetrical design. Even the chin of the phone is completely symmetrical with five holes on either side of the USB Type-C port. The bunch of holes on the right are to let out the speakerâs sound, while the ones on the left hide the mic beneath.
Coming back to the overall design, the Mi 4s feels like a cross between Xiaomiâs Mi and Redmi lines. Very honestly, it does not feel the premium phone Xiaomi want us to believe. Not that it feels flimsy for cheap â far from that â but not flagship material.
Xiaomi stick to the usual recent apps, home and back button (L to R) arrangement. Theyâre backlit, as expected.
Both sides of the Mi 4s are covered in glass. However, the rear side feels more like soft rubberised industrial plastic than glass. Other things you find on the rear: the Mi logo, the oblivious fingerprint sensor, and camera lens (that doesnât protrude, thankfully) with the dual tone dual LED flash.
On the top, the 3.5mm earphone jack (on the verge of extinction?) sits next to an IR blaster and a secondary mic. Iâm not sure if itâs me, but Iâm yet to meet anyone who actually use their phone as a universal remote (beyond just having fun like turning off TVs at the TV store).
While the Mi 4s is extremely comfortable to grip, it does skid off surfaces very easily (and ever so slowly, so you donât notice).
In a nutshell, the Mi 4s is a phone that is extremely comfortable to hold, easy to operate thanks to the screen size, but doesnât feel as premium as the makers meant. The thing works exactly like you expect it to, but it doesnât feel like a flagship phone.
Xiaomi Mi 4s Review: Hardware
The first thing I noticed about the Mi 4s was the screen (duh), and that it had a bit of a yellow tinge to it. While it felt out of place for the first few minutes, my eyes quickly got used to it.
However, not everyoneâs going to like the tinge of yellow on their phone screen. Xiaomi do offer users the control over screen colour temperature, so phone screens should be tuned to be as natural as possible â leave the rest to the user to configure. Unfortunately that isnât the case with the Mi 4s.
Besides that, the 5-inch 1920 x 1080p IPS display seem to be up there with the Mi 4. Good viewing angles, decent visibility in sunny outdoors.
Audio wise, the phone leaves a bit to be desired. While sound from the 3.5mm port comes out just fine, itâs the built-in loudspeaker that can sometime feel a little dull. No qualms with the quality of audio though.
Iâd say battery life is somewhere between good and impressive. It shouldnât be a problem to achieve the famous âall day batteryâ on the Mi 4s. The charger that Xiaomi ship also supports Quick Charge 2.0.
In general, you can expect around 5.5-6 hours of screen on time on WiFi. On 3G, expect about 4.5 hours.
Xiaomi Mi 4s Review: Performance & Benchmarks
I expected a slightly better performance from the Mi 4s and the hexa-core Snapdragon 808 (also seen on the Mi 4c). While I havenât tested the Mi 4c myself, I have a feeling that it is the MIUI ROM thatâs acting as the bottleneck on the Mi 4s. The phone has already had a couple of updates, but I expect it to be more optimised in the coming weeks.
Something that might be a problem for some is the heating issue that the phone faces. It doesnât get too hot, but the problem is that it gets hot too soon. CPU throttling kicks in then, and makes the phone slow to respond. Another something that should be fixed with future updates.
Iâd say that the Snapdragon 808 is quite a capable SoC, and that the Mi 4s doesnât seem to be making full use of it (yet). It doesnât feel like a phone with 3GB RAM and a high-mid-range SoC such as the SD808 so far.
Ironic but Iâve had better general performance on the Redmi Note 3, so there the Mi 4s definitely has a distance to go before it starts being considered for buying lists.
A nagging bug that the Xiaomi Mi 4s faces has to do with WiFi. If youâre using mobile data and then connect to a WiFi network, the phone will sometimes continue using mobile data. Refer to screenshot above.
Xiaomi Mi 4s Review: Camera
Xiaomi have yet to disappoint with a phone camera. Yet again, the Mi 4s comes with a really nice camera thatâs capable of taking some lovely shots⊠not only in the day but also in the night.
Photos arenât up to the level of what you saw on the Mi 5 review, but yet Iâd rate this camera a couple notches above the Mi 4, which itself is one of my favourite phone cameras so far.
Have a look at some photos.

Xiaomi Mi 4s Review: Conclusion
Iâd say that the Mi 4s is a nice phone with a lovely camera. Retailing at over $300 at the time of writing this review (for international buyers), the market doesnât really have a spot open for a phone like this one. Iâd be wiling to consider this phone myself at $250, that too because it comes with 64GB as default. For now, the plethora of Helio X10 phones in the market will do what youâre looking for.
Anyway, if youâre interested, you can get an Mi 4s for yourself in Gold or White from Banggood.com, which is where we get our sample from.

Nice review Yash, I like the little slow mo video touch
Cheers
no idea why itâs showing in SD here, looks way better in HD
I was very confused why your bat is flat and he is throwing the ball to the ground. That is not how baseball is supposed to be played!
(I know fully well what Cricket isâŠ)
What I read here is shocking â the perfomance issues, overheating â none of that Andi reported in the Mi4c test âŠ
Also the loook of the phone is a bit repelling â huge borders around the screen definately donât make it a $300 range looking one. Looks like th most premium factor in this phone is the presence of 64GB of internal memory âŠ
@Yash, did you experience any WiFi, radio range problems due to presence of metal border?
There is a WiFi issue the phone suffers from (mentioned in the review), but itâs got to do with the ROM than the metal body. Also, like I said in the review, the phone does not overheat; it just heats up too soon (doesnât get any hotter than other phones though).
As per WiFi itâs probably a soft bug only, doesnât sound as dramatic, as some metal framed phones have.
CPU overheating â ok, but it kick the throttling in, which is a show stopper for me âŠ
Also, you donât say a word about the quality of fingerprint scanner performance. Any remarks here? Maybe add few words to the articleâŠ
Thanks for that, Iâll add a quick update.
thats a good mid-way drive in the slomo :p
(im more of a football guy so pardon any mistake in the cricket terms)
iâd have to say tho , rateâs a bit steep for a phone that has an OLDER processor⊠Xiaomi need to do more to stay afloat and stop lacking..
A nice phone, just a bit overpriced.
Slightly more than âjust a bitâ IMHO.
Few guys on a different forum (non-English) managed to get the Mi5 basic model for $285 thanks to promotional cashback action (20% on shoping from selected webshops, sorry guys you have to speak Polish to use it) â this looks like a brilliant deal. Even if this one was avaialble for same $285, I still would be hesitant.
Mi5 suddenly looks attractive in the light of problems Yash mentioned. Whatâs wrong with Xiaomi? â Mi4c doesnât have these problems.
To be honest, Mi4s looked way better on pictures I previously saw. Now I donât think it looks better than Mi5 anymoreâŠ
If they fix the bugs (which isnât sure yet) and if the price drops, this phone can be an interesting choice. Now itâs only curiosity, and a way overpriced one.
It is way overpriced but it looks 100X better than the Mi5 IMO.
Those pictures are not very good..Anyway I have the mi4c â and donât have any of these problems. Infact, the pics on my phone look better.

Not useful firmware? Try MIUI Tweaks xposed module!

Much expensive!
Well well well, at last Xiaomi have released their own âVowneyâ in the flesh.
The difference is Xiaomi will improve most of the problems through software updates.

well after readin this : âIâd say that the Snapdragon 808 is quite a capable SoC, and that the Mi 4s doesnât seem to be making full use of it (yet). It doesnât feel like a phone with 3GB RAM and a high-mid-range SoC such as the SD808 so far.â it totally remindes me on my expirinece with Mi4i. i had a same feal about Redmi 1s comapring it with Mi4i, it was better final product.
this is yet another half baked product thati Xiaomi is promissing to fixâŠbut when!?
for itâs price i would say it is good phone, but there are many other better choises, and for Xiaomi fans, how can they justify by giving a premium on price of Redmi 3 or that for âonlyâ 100$ more they could buy real Xiaomiâs flagship?
You can get Mi4c even below $200 now, 3/32GB Prime option, without the silly bugs like in here and without the throttling fckup. Community does even offer alternative CM ROM for it. All these after you agree with the lack of SD slot and finger scanner. Does it make any sense to pay 50% extra for the experience this Mi4s privides?
Also, as you say â Xiaomi is promising â they actually arenât. All they promise are software upgrades and recently they focus more on adding some completely irrelevant crap in it, than actually fixing known bugs, or really improving it. This company seems to be forgeting what they grew on.

Great reviews Yash! I have seen a user video where he talks about and show the yellow tint of its MI4S screen. For me thatâs a huge downside, apparently the user hasnât been able to fix that annoying issue using the screen parameters defined in MIUI. Some of his friends who bought the MI4S have the same problem. Your review confirms the information gathered on different websites. The MI4S with a screen quality similar to the one used in the MI4C with an upgraded SOC like the SD652 or even SD650 would have been a lot better.
I am left with the following phones in my purchase list:
â Redmi 3 Pro (wondering if the 720P will be enough, waiting for feedback regarding the SD616)
â Redmi Note 3 Pro (which is bigger)
â Xiaomi MI4C (no SD card slot, battery life is not perfect)
720p should be fine on a 5 inch screen if they are using a high quality LCD panel.
My nexus 5X has had the yellow tint issue, but it was later fixed via software update. One can really calibrate the screen any way one wants (via built-in ROM feature or root).
I love the design of it and would have preferred this to be the design of the Mi5. As for IR it is one of the things I miss most about my Mi4, I used mine as a remote everyday.
Why do you think itâs overpriced?
Are there better or comparable phones with the same size (5âł) and features (metal edge, fingerprint, good software support)?
It is overpriced compared to other Xiaomi 5â models:
Redmi 3 Pro: $160
Redmi 3: $135
Mi 4: $135
Mi4c: $200
And those are reseller prices. This should have been priced at most around $225, given that it is only a marginal upgrade to the much cheaper Mi4c.
For the features it offers I think the price is ok.
If someone want to prove that itâs overpriced, please provide a competitor with similar features.
None of them have 64GB storage build in.
Mi4c is just plastic and doesnât have fingerprint scanner.
By the way, on kimovil the reseller prices are as low as $256.
If you think a fingerprint scanner is worth an extra $100 than so be it, I donât. The $256 is for the 2GB/16GB model. The 64GB one is $298-355 from that seller.
Haha, you notice the 64GB, but not when adding to the $100 price increase. You also ignore the premium build materials.
Just for fingerprint I wouldnât pay +$100 either.
The build materials are mostly cosmetic, Mi4c has excellent build quality perhaps even better than the Mi4s/Mi5. The really only difference between the C and S is the finerprint scanner and extra storage. Neither of those are worth an extra $100 to me. To you maybe they are. For me it is a slight upgrade to the C and that should be reflected in the price. I would have a hard time paying $300 for a Mi4s when I can get a brand new flagship for not much more. If it was around $220 I would buy one.
Many manufacturers charge $100 just for 32GB to 64GB upgrade.
Which brand new flagship (you mentioned) would you buy instead?
Meizu Pro 6, Zuk Z2 Pro and if it came down to it i would buy the Mi5 instead too. I hate the design of the Mi5 but I think itâs a better overall phone.

I should ask that to Linus from Gizmochina. Some shops are slowly reducing the prices for the Redmi Note 3, MI4S. Do you believe that Xiaomi will release a 5.2âł budget phone soon?

The âqualityâ (or lack of) of this phone seems consistent across reviewers. The metal bezel doesnât feel quite âmetalâ, yellowish screen, and heating issue. Same impression from me.
Could Andi review Mi4s camera again? I mean I would like to see what Andi really think about Mi4sâs camera after reviewed the Mi5.
