I have 450X series one and when i took delivery from bannargetta road i went to ather space indira nagar to charge it when it was above 85% it took 30 min to charge for 7 kms in eco mode . When i charged it with the dot charger the app said it will take 2hrs for full charge whereas the vehicle charged in 1 hr itself to full 100% . Again when i recharged it did not do slow charging after 90% . is there an issue ?
