Not up to mark to be called a Flagship
By Sanjay Mishraon
I have been using this product for 2 days and its the review based of the 2 days of usage
1.Its heats up like anything even for normal Browser usage
2.battery backup is about 1 day 4 hours with Single Sim (2G) and wifi on continuously on single charge,with minimal usage i.e 1 hour youtube,minimal calls and other Social Networking etc.
3.The call clarity is awesome, the sound is clear and crisp,but after making calls for 22 minutes continuously,I felt unusual heating near the earphone thats very irritating.
4.There is bit of Lag in the UI,can't be sensed so easily ( I felt lag while toggling from one app to other) hope Mi would come with an OTA for this
5.At the first Boot I got a Ram of 1Gb from 2GB,but during usage after killing all apps u get something close to 800 mb ram.
6.At the first Boot the internal Storage of the phone was close to 10.6 Gb after removing unnecessary preinstalled apps the memory came up to 11.45 GB (with NO other apps loaded) since there is no Option for memory card you have to keep a Pendrive with you and transfer your clicked photos via OTG.
7.the camera is descent takes good photograph,but there is lot of noise in low light conditions,which will literally spoil the pics,so this phone doesn't perform well in Low light
8.Gaming was just Ok with too much heating,there is something strange in Mi 4i that even the Screen heats up dangerously.
9.The tall claim of Xiaomi as flagship device for India is'nt apparent after using the Phone
verdict:
If heating and short memory storage is'nt an issue the phone is the best.hope xiaomi will come with an OTA in order to curb the heating issue.
HEIGHTS OF AWESOMENESS......:)

IMPORTANT POINT:

This phone is excellent in terms of style, performance, battery and camera.
Too weightless and had a mat finished like back panel
Cant say that this device didnt heats up...actually it does..but only when you are charging or using mobile internet.
MIUI is as fluid as iphone..in fact its superior with a lots of features; like "one hand use",themes etc
The only con i had found is that the sound is only average(or below average).
Display and camera are excellent. (both rear and front)
superb call quality
Battery is more than average than other android phones.
All the sensors are working perfectly.
Will update this after a months usage.

Edit:
Have been using this for almost 3 years and 3 months ..still works like a charm.. only drawback is non expandable memory.. since i keep my phone clean most the times, that's acceptable to me.
Had replaced the screen twoce in this period due to broken display.. but it's completely my fault.
Camera works better than current mi models at this proce range.
Excellent flagship for an unbeatable price

Overheating?: I was initially concerned about the reports of overheating from reviews on FK as well as from some reviewers. After using the phone for a few days I have not experienced any overheating. Like all phones, it gets a bit warm if you use it while charging and also for highly intensive games. But even during gaming, it never got too hot, just slightly warm. This is on Asphalt 8, Subway Surfers and Clash of Clans.
Design: The device feels extremely great in your hand, even better than the Mi 3 and much nicer than the bigger phablets like Zenfone 2 and Honor 4x. The matte finish make the device feel premium. Every person I have shown my phone to has first commented on how light it feels, but also remarked how solid it is.
Battery: The battery has been great, easily lasts me a day with some room to spare.
Display: This is the main reason why I decided to buy the Mi 4i. The display is unparalleled in this price range and even in 20k+ devices. 1080p display just looks beautiful. The Corning OGS glass is same as GG 3 and makes me feel safe with my purchase. Also, I thought Sunlight Display was just a marketing gimmick, but it actually makes it easier to use my phone outdoors.
Performance: Really love the performance of this phone. There are some minor lags after playing games for 30min+. Once the device cools down again it works as normal.
Overall: Best phone since Mi 3. Don't believe the overheating reports until you actually use the phone. I was worried after watching a YouTube video showing really bad overheating, but he switched on performance mode. I have not seen any overheating in default mode and am still able to play all the games I want.
