I really need help.
My problem with charging the battery, before I update to v1.8 marshmallow battery charging times with the original usb 6 hours, and non-original usb 8 hours.
After I update to v1.8
- Charging from 15%*" to **90% takes 13 hours
- 15 h full battery.
6 hours is very long especially until 15jam, I am saddened by this.
How do I downgrade to a previous version without reinstallation, because the data I've pretty much.
I say thank you very much for solution.
