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.

Harddeep, 31 Oct 2018There's something confusing here for me in this review. Ca... moreIt is power efficient because it is fabricated using 14nm FinFET process while the MTK one is manufactured by a much larger 20nm TSMC process. The thermal as well as power efficiency decreases exponentially with increase in process size. 20nm processor generate way more heat and consumes more power than a 14nm FinFET processor.

      There's something confusing here for me in this review.
      Can someone explain, how does it come the Snapdragon to be more energy efficient, when it sports 8 cores all of 2GHz, while the 10-core Helio has only two performance cores (which will be usually off, right?) while the rest are four average at 1.83 GHz and four powersaving cores at only 1.4 GHz? I thought it's those low-frequency cores that spare the battery? And when I see those octacores all at 2GHz for mobiles, I thought what a crazy thing, why those manufacturers don't care about battery, but now I learn it's actually more efficient?! How come?

          Redme note 4 doesn't seem to be a good choice while you get reasonably good other phone on same cost. I had a bad experience with it since it gets hanged and finally it got locked. It's too difficult to find service for that as well. Myself and my brother purchased phone on same day, he chose to buy samsung and myself chose this because some others in my office told me its good. But ultimately i find my brother had a good choice since his phone is still good

            AnonD-516958, 05 May 2018Hello everyone, bought this set from daraz.pk in 15,999 PK... moredear, install Antutu and check the brand of your chip-set, daraz is providing Mediatech version whereas the real version is Snapdragon, if yours is snapdragon then it is really a good deal, secondly please check your notification light is properly working after acquiring updates?

                  Hello everyone,
                  bought this set from daraz.pk in 15,999 PKR and its really a good set with this price range.
                  Out of the box its android 7.0 with MIUI 8.5 ! After connecting it to wifi we get update of MIUI 9.5 which is a good update !

                  Battery performance is very good,
                  no heat up issue in my set.
                  camera is good ( it came out with decent pictures from both cameras)
                  Speakers are average
                  microphone could've been much better
                  screen is good

                  Overall for this price range i say its really a top phone !!

                    I am asking about Indian unit

                      I purchased redmi note 4 yesterday and is color accurate in standard screen mode as mentioned in reviews. Is the color accuracy maintained if i upgrade to nougat and miui9 and are there any issues after upgrading. Kindly reply, Thanks in advance.

                            This phone supports fast charging, but on miui. I flashed custom rom and finally compatible with my qualcomm fast charger. The performance of the parts/modules are software related, so tests like this are simply pointless.
