Battery & Charging Time
Redmi Note 11 comes with a 5000 mAh battery. Samsung Galaxy M21 (2021 edition) offered a 6000 mAh battery. But the display time offered by both the phones is quite the same. There is no significant difference.
While using Samsung M21 I didn't know about the "Digital Wellbeing" feature but I checked those metrics on Redmi Note 11. From there I calculated that 100% battery can offer you 7-8 hours of display time. Now it will vary as per your usage pattern - which apps you are using, network conditions, etc.
Talking about charging time, Redmi Note 11 takes around 1 Hour and 10-15 minutes to make the battery 0-100%. However, in the case of the Samsung M21, the charging time was more than 2 hours 30 minutes to make the battery full.
The reason may be Samsung offered only an 18 Watts charger. But Redmi Note 11 comes with a 33W fast charger.
I think, If I use it as a common user, Redmi Note 11 will serve me the entire day in a single charge. However, I do lot of online searches, watch YouTube videos and other social media applications are also there - so it is not serving me more than 7 hours in a single charge.
User Experience with Redmi Note 11
First talk about the camera. The Samsung M21 camera was fantastic, Redmi Note 11 camera is not that good, though it has a 50MP main camera lens along with a 13 MP front camera.
Samsung M 21 came with a 48MP front camera and a 20MP back camera. I was very happy with the camera quality of Samsung. But I saw some YouTube videos where many were saying (commented others as well) that Samsung M21 will face a Motherboard problem. So I thought, it's better to return that - and will purchase another Samsung when my budget will become higher.
Overall experience with Samsung M21 and Redmi Note 11 is quite satisfactory.
Talking about the heating issue, both the phone heats a bit during charging, continuous browsing, and especially while I write blogs on my laptop and take internet through a mobile hotspot. But as per many Tech review channels that are common -- every smartphone will heat up like that.
Should You Buy Redmi Note 11
I think this is a very good phone at this price range. But when I compare Redmi Note 11 with Samsung M21 I feel the Redmi Note 11 price is slightly higher.
Samsung M21 offers you a 4K video recording feature at just 12K. Whereas Redmi will cost you 12499 to 13499 Rs for the base variant ( 4Gb 64 Gb).
But the Samsung M21 lacks in its Processor - Exynos 9611
However, the 6nm Processor of the Redmi Note 11 is not an outstanding feature too. I don't feel any performance difference between Samsung M21 and Redmi Note 11.
The point is that, if you are looking for a budget phone for normal use you can go for both the phone. Samsung offers you better features at a lesser price than Redmi Note 11. But the only risk factor is that if after one year the motherboard fails you need to spend 7-8K to replace it.
My first phone was Redmi 5A. With that phone, I never faced any significant hanging issue or any other issue till 3 years. Recently the battery is draining fast of that Redmi 5a phone and heating issue is there so I changed it. But in the 3 years of service, I never faced any issue with Redmi 5a - that can be one reason that this time I also bought Redmi. Though firstly I bought Samsung M21 2021 edition from Amazon, but returned it and bought Redmi Note 11 from Flipkart. Now I can't return anymore - no need to do so as well.
