I bought the cell phone already used, so the battery is already 80% close to the original capacity. In my evaluation I put that the battery lasts for 1 day considering a battery with full capacity, which is not my case. Regarding fluidity, without words for Android One. In my opinion it is unbeatable to have a simple system without frills.
I'm having some inconvenience with the screen brightness. Not always he adjusts the brightness when there is more light in the environment, so I have to change it manually. About MIUI, I think it's personal, but I don't particularly like it. I believe it would give me better with some Android One line phone, which comes with the clean system. On the other hand, I think the speakers are not of great quality, but I can't wait long for the price range.
Need to replace the original ROM with another, parallel. Suggestion is the Asus Zenfone ROM available in the 4pda or XDA, but also has the Lineage of the Redmi 5A (the digital sensor does not work, but it is a cleaner ROM). As for hardware, everything in it is suffering, but ends up being consistent with the amount paid ($ 280.00 in my case). The internal memory must be of inferior quality, because it is perceived a slowness above normal when copying / moving files, and this ends up negatively impacting on the use in general. I also noticed that his bluetooth is not there, too, and it chokes even without parallel apps. But for a secondary use it is a great device. I had a Redmi 5 with 2gb / 16gb and snap 450 and I thought it worth more for the amount I paid on Xiaomi ($ 500).
I was able to change the Xiaomi ROM for a version 9 (foot) custom. However, I had to revert to the Xiaomi ROM because the bank applications did not work in custom ROM. About the camera, it has a very good quality for the price range. The screen is also very good. Given the price difference being low, I recommend the Xiaomi Redmi S2 instead of this device (if the Xiaomi rom is not a problem).
