Using xiomi for 7 months feels very better. First of all I am proud of its battery life.almost 2 days for my normal use. If we use it for a full day internet and playing games the battery will end in the night.battery is non remivable.excellent build quality.look so stylish and attractive. Supports 4g volte downloading is very faster. Camera quality is good.front camera is bad. Sim card is hybrid dual ( micro + nano) or an sd card. It was having full hd display so videos are playing in high quality. It supports all types of remote functions in the app mi remote. Anyway it is the better android for this chep rate
