LeEco Le 2 charges slowly after a factory reset

[maclee4real]

Hello Everyone,
I recently ordered a phone 3 months ago. and I must confess, its a nice phone.

And I believe it is a stock ROM. One day after updating all my apps successfully, some days later one of the app (dictionary) started giving me a false update. It will display downloading then the status of the download is paused. Whenever I click on the item downloading it will do nothing. If I reboot the phone, more downloads will appear and so on. So I uninstalled the dictionary app thinking it will stop, but that same downloading still appeared. Then I decided to do a factory reset on the phone but before doing that, I backed up my apps including system and user apps.

After the factory reset, I installed all the applications but I keep getting "sorry google play services has stopped" error messages, I have updated to the current play services 11.7.46 and I am still getting the same error message.

And the most annoying thing is that, after the reset, the phone stopped charging fast, though the fast charging is enabled, now it takes for ever to charge to 100% and it discharges fast too and when charging, the battery temperature raises above 45 degree.

So I believe that the factory reset removed the fast charging from the phone.

please I need help on what to do
thanks
