The Gionee M7 Power's claim to fame is a big battery & a 3-D photo feature
December  11 2017:  Mobile phones today are often used as the primary screen,  to view movies  -- and  the  only tool to shoot  pixel-heavy photos and  videos. These are all  power-hungry applications and  can drain away the battery in quick time. Which is why a device like the Gionee M7 Power  will be welcomed by such   heavy users. It boasts a jumbo 5000 mAh  battery  with   an intelligent  system which squeezes even  more juice by clever power management.
In other ways this is a fairly standard handset for its price -- Rs 16,999:  4GB RAM and 64 GB  storage expandable to  256 GB;  13 MP rear camera with flash and an 8 MB selfie camera with a built -in 'bokeh' filter to blur the background;  fingerprint  security sensor;  a 6 inch,  18: 9   aspect ratio and' full view' --  the maker's  jargon for a bezel-less  display--   with 720p HD resolution;  an Android Nougat OS embellished by  Gionee's own Amigo 5.0 user interface.  The phone works with 4G VoLTE networks and has dual SIM slots.
Among pre-installs is the  UC Web browser  which means a lot of India-specific resources. I am guessing, the key feature ( other than the battery on steriods) that will sway purchase decisions is the M7 Power's   3-D photo feature. In  this mode you can shoot all around an  object or location  and it will translate into a dynamic 3-D, 360 degree image. Yes other apps like Facebook allow you to do this; but it is an advantage to have it as a native feature on the camera. Another minor, if useful soft tool is the ability to create 3 WhatsApp  accounts.   You can also split the screen between two activities.
In short a cool mix of  hardware and software features coupled with a battery that will sustain  you through the heaviest  apps. Vishnu Anand
