Even I was one of xiaomi fan who had an MI3 and powerbank from MI. Inspired by these products I purchased this Mi4i on the flast sale on 28th July 2015, it took 6 days to deliver the product. On 3rd August I received the handset and was curious to enjoy this piece. But my expectations was in vain, as soon as I switched on the phone, severe heating and batter was at 3% which I thought its common in a new smart phone. So I switched off the phone and put for charge for 4 hours and later switched it On, BATTERY HEATING ISSUE was still there and the BATTERY DRAINING was like flowing water within 1hour the battery was at 10% .
I contacted the call centre for this issue they said me to do some tests and finally said ITS A BATTERY ISSUE AND ITS COMMON IN ALL Mi4i.
This response was said easily by the call centre person.
Asked me to go to service centre for a free Battery replacement.Man its a new phone and they are easily asking me to waking to a service centre.
Worst and pathetic service and call centre.
I have wrote this to all major online Gadgets reviews.
And more over they are not in a policy of RETURN ORDER which most of the major ecommerce business has it like Amazon and Flipkart.
Please friends never buy this phone, they are cheating people and no service even for day old product.
