Gionee Marathon M5 Lite has a very good battery life of nearly about 4000 mAh . I purchased this smart phone as it has a very good battery life. But it charges very slowly , I guess the company should improve the charger from its next flagship. For the beginners and people who don't have time to charge the phone repeatedly but can charge once till full potential , this phone is great but for people who need the mobile phone always and cannot give time for charging , I would say not buy this one .
