Namaste, I am using Oneplus 2 that I bought for 16k 18 months, noticing battery issue, taking time to charge and draining quickly, with flip kart sale they are offering 4.3k plus 2k extra for exchange and I have citie bank card, overall I am getting Honor 9i for 10.8k, can you please let me know if that is a good deal? I need mobile mostly for taking calls, Skype, slack, Twitter and email. Or should I just replace the battery and keep using my current mobile. Thank you very much for your time. Srinivas. Ps. Amazon don't offer exchange to my city.
