Micromax canvas tab P480 battery is 3000mAh but it down in 1hours. It is very infficient battery to this tablet. Tablet has 1GB ram it good but it does not faster performance. It is hanging after we play big size games on it. Storage of tablet is 8GB but it not 8Gb. I expandable its storage to 32GB sdcard then tablet heating too much and its hang more than before. So it not compatible 32GB sdcard. Tablet display is very large 7inches but not big things important the quality of that is very important and it does not. Camera of tablet gives very bad quality of picture. The micromax canvas tab p480 is kids tablet.
