Battery backup problem of Spice Mi-525 Pinnacle FHD mobile phone

Hi friends, I purchased Spice Mi-525 Pinnacle FHD from ebay , a superb phone for the price given with full HD screen, really nice and crisp but I have problem of battery backup, the battery backup is very bad, it lasts only 5-6 hours even if I am just using it for internet and surfing, please suggest me how to improve its battery backup ?

Since its a full HD phone then battery backup will be poor always. You can reduce number of application running at once, remove unwanted apps, dim your brightness, turn off bluetooth, wifi and data connection when not required and should increase your battery backup.
