Xiaomi Redmi Note 4 (S625) review: Take Note!

27 March 2017
After getting to know Xiaomi's Redmi Note 4 with Helio X20, it's time to meet the Snapdragon 625 edition. It promises better battery efficiency and thermal control thanks to the more advanced manufacturing process. But these improvements may have cost the Note 4 some of its performance punch, and we will duly explore this possibility.

Miui is heavy and too animated. Build quality on 3T is world apart and long term software support us welcome too.

      After a lot of research I found these are the 10 differences between Redmi Note 4 (MTK) and Redmi Note 4 (SD) / Note 4X:

      1. Note 4 (MediaTek) has MediaTek Helio X20 (MT6797) CPU with Arm Mali-T880 780MHz GPU - Note 4 (SD) / Note 4X has Qualcomm Snapdragon 625 MSM8953 with Qualcomm Adreno 506 GPU
      2. Note 4 offers 4 colors: Gold, Gray, Silver, Black - Note 4X offers 5 colors Black, Gold, Pink, Silver, Turquoise
      3. Note 4 has all metal body - Note 4 (SD) / Note 4X has mix between metal and plastic (plastic are downside where micro USB is and upperside where 3.5mm connector and IR port are; i.e above and bellow antenna lines)
      4. Note 4 has dual band Wi-Fi 802.11ac conectivity - Note 4 (SD) / Note 4X does NOT have dual band Wi-Fi 802.11ac conectivity
      5. Note 4 has weight of 175 g - Note 4 (SD) / Note 4X has weight 165 g
      6. Note 4 has screws on micro usb side and can easily be opened - Note 4 (SD) / Note 4X has no screws on micro USB side and I didn't find anywhere how to open it.
      7. Note 4 has IR port in the middle of upper side - Note 4X has IR port on side of the upper side (this means Note 4 cover will not match with Note 4 (SD) / Note 4X)
      8. Note 4 has compass - Note 4 (SD) / Note 4X has NO compass
      9. Note 4 has Samsung S5K3L8 camera sensor - Note 4 (SD) / Note 4X has Sony IMX258 camera sensor
      10. Note 4 does NOT support fast charging - Note 4 (SD) / Note 4X does support fast charging

      Please correct me if I'm wrong

        "MIUI 8.0 is built on Android 6.0 Lollipop and runs fast; theming and options for notification area, app switcher, etc. make it easy to find the look you want." - So, is it on top of Lollipop, or Marshmallow?

          RN3 international/special edition (kate) supports more LTE bands than the RN4 international version even if both support B20.

          For Australia, New Zeeland, Taiwan, South America and North America RN3 (kate) is the better choice because of B28 and B2 (in addition to B4 supported by both).

            zodiacfml, 28 Mar 2017the SoC is fine, probably even better than the X20. It is ... moreThe mediatek x20 is a flagship grade processor which I'll choose any day against the midrange SD625.. The battery life isn't all that much considering the x20 has a powerful a72. Stop looking down at mediatek processor.

              the SoC is fine, probably even better than the X20. It is just that the battery is so large in this phone that battery life difference to the X20 is not too large. In a slimmer or smaller capacity battery, the SD625 will prove its massive efficiency.

                Aslipundit, 28 Mar 2017Just wanted to add; The black colour variant is sexy as hel... moreThere is a black version with X20, it came before the S625 one. Anyway, four A72 cores is of no more use than two A72 cores in practical performance, it just drains battery.

                BTW, what modem issues is he talking about in the review? I didn't have any problems with my RN3 phones (kate and kenzo models).

                    I think redmi note 3 with sd650 still better, its offer good balance in performance, battery life, & camera. Not mention also price dropping right now.

                      How can battery test for Redmi 4 Prime are worse than Redmi Note 4 (625) ?

                        The article should mention, that the snapdragon 625 comes with different LTE bands. Namely B20 is super important in Europe. The Helio X20 version did not offer us full LTE. When you moved out of a city, you were on 3G or even 2G. You can buy both versions in Europe. But I will strongly suggest you take this new one to get the more out of your smartphone.

                        And btw the article should really mention, that both versions come with different LTE bands. It's very important for a potential customer.

                          Why dondon't u add moymoto g5 lus as a option of redmi note 4 !

                            Just wanted to add; The black colour variant is sexy as hell. I wish they had it for the X20 powered versions.

                              The gpu will ABSOLUTELY make a difference in real life, especially for gaming and graphics heavy applications. Try playing Real Racing on the highest settings on both settings and notice the clear difference yourself. The Adreno 506 is adequate for 1080p gaming, but will struggle with the latest games at high settings. The 510 in the Note 3 Pro on the other hand will play most games ok at the highest settings, as will the similarly capable Mali in the Mediatek powered Note 4.

                              What the article doesnt tell you is the fact that its not just the two missing A72 cores & a stronger gpu in the X20 that makes it quite superior to the SD 625. The X20 has dual channel DD3 memory (933 mhz) which gives it 60% more bandwidth than the SD 625 which has only single channel memory. Bandwidth is precious in Mobile SOCs due to a single memory bus which is shared by the different components & impacts 3d performance. For comparison, the SD 650 also has dual channel memory at the same frequency as teh X20. Even the SD 800 from 2013-14 has more bandwidth than the SD 625.
                              The one and ONLY advantage for the 625 is better battery longevity, thats about it. If all you do on your phone is light browsing, face book and media consumption, by all means go for the 625 Note 4 as it will last you longer and you wont really notice the difference.

                              But if you do any processor & gpu intensive tasks on your phone, you are much better off with the X20, 650/652 or the older 810 & 808 (heating issues not considered).

                                the j7 prime price is dropping closer to the rn4 but i dont think people will go for it.

                                  Can anyone tell me how to use the online streaming in MIUI official music app?

                                  I couldn't find it anywhere

                                    Am I the only one who hates this new trend of OEMs prioritizing battery life over performance? I mean yes, I understand that battery life is way more important to most people than performance, but for power users like myself I find this new trend very disheartening ☹️

                                      Another notable feature is wifi 5g ac which had been removed in X20 Note 4. Kudos on Xiaomi to bring back this while keeping price competitive.

                                        When considering value factor, xiaomi offers on par with the most "value for money" brands like leeco and Meizu, but no one can beat xiaomi in battery life. Mi5 had best battery life in all flagships except s7 edge. Mi5s plus had best battery life among all the flagships announced last fall. Redmi and redmi notes are the king of the Hill with their 4100 mah batteries. And Mi Max is also the king of battery life in its class.
