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.

The Best in class. Fantastic user interface. Superb speed. Sleek look. Awesome battery back up. Fabulous display clarity. Smooth touch. On the whole this is a very good product at affordable price beats all the other market leaders.

As usual great service by Flipkart, on time delivery. I am using this phone from past 1 day now. I was setting this up with usual stuff like accounts, wifi and sound etc, it started getting heated up. Even 10 mins of subway surfer like games gets this phone to get heated up. Otherwise phone is decent with miui v6, good camera etc. I have mi3 which is pretty solid in this area.

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.

Awesome phone...no lags..no heating problem...great UI.... + Battery + Camera(front n rear) + UI + SCREEN :} + NO LAGS - No headphones - lack of accessories in market IMPORTANT POINT: Update your phone before using it, there is a update of 800mb. IT WILL SOLVE THE HEATING ISSUE ETC.....

looking very beautify and also looks very slim camera is good video recording is also good screen resolution is very good MiUI 6 is so good mobile performance is also good but little bit heating issue....

Good Phone, using for 5 years

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. _____________________________________________________________ Don't hesitate. Its the best you are going to get at this price ! ____________________________________________________ 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.

Issues with the phone. 1. LED leak at bottom of the screen, under the back-lit buttons. 2. Phone overheats even with brief usage on 3G/WIFI. Have requested for return. Waiting for reply from Flipkart.

Please don't buy this product.its like a heating pad.I just started setting up the phone on first boot up the phone got heated up and it is really unbearable to use.
