Vivo v9 has a great ?? of 3260 Mah. Its very good in battery backup. No need to carry power bank.etc.
Battery life is about 1day. If continues use.
I like its battery capacity. Because we all looks for a better battery backup mobile. So v9 is good for battery back up.and one more thing.
In v9 the extra feature supersaver mode is very beautiful move. Im really very happy with that. Because if the battery is only 15% .then if we on that mode. It will turn in to a feature phone like keypad mobile. And it gives abattry backup only with15% it will give 2hours of long lasting backup. It is very useful.
