Dear all


Just wanted to bubble up some issues regarding the recently released Redmi Note 4. For clarification purposes, I am using the Redmi Note 4 (3GB, 64GB) Variant running on latest MIUI Chinese ROM 8.0.11.0


  • Battery Drain

    I really do not understand how a 4100mAh phone can be so inferior in battery life. It could only last me slightly more than half a day (5-7 hours) before the low battery notice shows up. And this is with low to moderate usage without any gaming or hardcore social media. Brightness is below 50% and GPS is not on most of the time. This is disappointing because the Mediatek Helio X20 Chipset is already very restrictive in it's operations, shutting down most of it's powerful cores 90% of the time. Yet, the battery life is mediocre at best and I really suspect it might be due to some software optimisation issues (My previous Redmi Note 3 Pro's battery does so much better with the samne amount of usage). Hopefully, MIUI software engineers can do somthing about this.
  • Overheating

    This brings me to the next concern that I would like to bring out after using the Redmi Note 4 for a few weeks. The phone does get warm quite frequently, reaching temperatures of 45 degrees and sometimes even higher. This has contributed to the battery drain in the previous point as overheating is a form of power inefficiency in the hardware aspect. It puzzles me as to why this still happens even after the aggressive Chipset restrictions that are already implemented. ( http://www.androidauthority.com/helio-x20-doesnt-overheat-671422/ )
  • Choppy Performance

    Yup, even though the Chipset scored quite well in benchmarks tests, it struggles in the operation of the UI and even struggles with multitasking after opening just 4-5 apps (despite the 3GB of RAM). With a Deca- Core clocked at 2.1Ghz, fluid UI operation is the minimum expectation but more than 50% of the time, choppy performance is experienced. As mentioned, this could be due to the aggessive Chipset protocol as the two A72 Cores are rarely operating even during heavy use. There are also some random instances of app crashes and the phone hardware simply feels like it isn't maximised.


In all, the software on the Redmi Note 4 (at least for the MIUI Official Chinese ROM) is not optimised. Not only does it struggle in daily tasks, it also reflects some serious battery drain issues and tends to heat up sometimes. It feels like a work in progress and really doesn't maximise the hardware in the phone.

To MIUI Engineers seeing this post, please address these issues, thanks.
