After the unboxing here is the Redmi Note 9 Pro Max review, I did the gaming test, battery charging test, heating test when playing high end games and battery performance after the gameplay.
This handset is powered by Qualcomm Snapdragon 720G octa core processor and the antutu score I got was around 277K which is pretty good.
I also played PUBG game in max quality mode (check video) and did play for about 30 minutes and saw a battery drop of 7%, you get an idea how long the handset will last playing PUBG non-stop. And heat build up was also under control did not go over 40 degrees.
As for the battery charging test as per Xiaomi the Redmi Note 9 Pro max takes about 30 minutes to charge to 50%, and as per my test from 40% to 100% it took about 58 minutes. So you can expect about 1 hour 30 minuets or so for full charge. Do note the Note 9 pro max comes with 5020 mAh battery.
Do wait for the Redmi Note 9 pro Max camera review coming soon.
