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.....
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.
Here is what you need to know about the phone before you purchase: The good: 1. Amazing display with display calibration and color gamut found in Apple Hardware. The sunlight readability works as advertised. 2. Well built with anti-slip matte back and very light weight. Easy to hold and won't drop too often unless you are butter-fingered 3. 'Flagship-grade' rear camera with quick focus, good HDR mode and great details and colors. Decent front cam, gets the job done but don't expect much detail in the picture 4. Good battery life. Lasts a typical work day with about 20% battery left. Obviously depends on usage pattern. For better battery life, keep the phone in balanced performance mode and 40-50% brightness set on Auto 5. Did I say, gorgeous display ;) The bad: 1. Performance is middling at best and doesn't deserve a 'flagship' rating. App launches are slow, sometimes won't happen at all. Signs of an unoptimised OS running on decent hardware. Expect a Day 0 software update of 800 mb+ which is a must-have else the phone overheats and performance stays sluggish. There is an update in the works which should fix most of the issues though. 2. Battery life could have been better. A problem possibly because of Lollipop 5.0.2. An update to 5.1 is needed to remove memory leak and battery life problems which should happen soon enough. 3. The balanced mode takes the life out of this phone. Multitasking is a pain, app launches slow down further and you can notice the stutter in animations. 4. Continuous camera usage can overheat the phone to the point that the camera app starts to lag a lot and the focus struggles. You will have to let the phone cool down to go back to smooth performance. 5. Severe CPU throttling when phone heats. Don't know if its the OS or the Snapdragon 615 problem. We will know after the Software update for sure. 6. 16 GB non-expandable storage with about 11GB of user available memory. If you keep a lot of media or love to take pictures, you might wanna wait for the 32/64gb one 7. The OS uses a lot of RAM. 1.5Gb out of 2 is usually taken by MIUI. This is not a deal breaker but definitely a drain on performance and battery life. Lots of other bugs which need a fix. 8. Only white option. If you've got to give only 1 option, make it black. seriously. NOTE to Buyers: If you see a lot of heating in general use or a light bleed below the backlit buttons, ask for a replacement right away. The heating problem is mitigated by the update so do that before you ask for replacement. The light bleed problem is due to poor panel lamination and replacement is the only option.
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.
After doing research on the latest phones , I bought this phone. Review of mi 4i after upgrading to 6.5.5 MIUI stable version PROS: Build is perfect for usage as well to place in pocket Amazing Screen Good battery life High speed network connectivity in performance mode(better than iphone6 in my test) HDR Photos are very good at its price range Got it for Rs,11,700 in Flipkart during offer days with 24-hour delivery One hand usage is good. CONS: Slight warm on continuous use of 20 min or more Volume and Power buttons are sharp at the corners(doesn't feel premium) Plastic body feels delicate, especially if you have kids Micro USB connector is not comfortable while plugging in or removing the pin(very tight) Limited memory Loud Speaker is not great; OK sound 1 GB is used by MIUI and if you open a couple of apps, the remaining RAM shows 700MB(RAM is not being used optimally) Some Observations in my usage Ran Antutu BenchMark Tests after OS upgrade: balanced mode 31k performance mode 39k Used the phone extensively in balanced mode Full battery got charged in less than 3 hrs with the 2A charger given along with the phone When using the camera/browsing/gaming for 30 min makes the phone warm (Not heating); Same thing observed in my htc also; felt not a problem Basic camera settings doesn't give very good photos; need to do small changes for good photos FaceBook app hanged once in my use. Network speed is amazingly fast (compared to my htc one X and iphone6) Screen looks little dull at 50% brightness compared to other phones at same brightness level Ran few games like temple run without any issues Loud speaker sound is on the lower side Receiver sound during calls also is not on the higher side; It is Ok 1 GB RAM is always used by MIUI; only 900MB to 1 GB left for the user. If you open large number of apps, may be a problem; Tried with 7 to 8 apps, no issues. Ran Asphalt8 for 10 min in balanced mode; didn't face any UI lags; but the device became warm beside the camera, checked the temp - it is around 40 (same thing on my htc was 40, but because of the material and build, i dont feel it much on my htc) may be because of the chipset density and octa core in mi 4i,so i am feeling 40 also as light heat on the outside.
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.
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....
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.
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.
Phone is pretty good !!!! No abnormal heating and the heat it generates is normal for a phone of this Kind !!! First Xiaomi Product !!! Happy with the performance !!! Camera beyond my expectations !!!! Total worth for money !!! Only concern is Service centers !!!! Hope ill not get any issues atleast for an year until I get another one !!!!
