abhi8dalvi91We coming here for looking solution , but you coming for support ASUS product ,it's very non sense of your comment.
I am using the phone for a year almost love when it was brand new but now people are not taking initiative to solve the customer care complaints the phone is although good no doubt but still its lacking proper support from leaders of asus
might they sort out the problem with battery as soon as possible with the update even you use a wattage of 45 charge it will charge the same showing turbo charge at take the same amount of time which is pain in back to just sit for hours waiting for phone to charge . Please take this matter as a concerned and i know Asus will do the needful .
Anders_ASUSI having also same problem
We've seen complaints but have received very few logs and none of them that can confirm that there's a software issue. Have you tried charging with a different cable? If the cable breaks, partly, then fast charging will stop working. This is a VERY COMMON issue which needs to be solved with your local ASUS Support.
If you have tried with the bundled asus charger and multiple cables without getting fast charge, then I would very much be interested in logging your phone to find out why.
