Here are my findings:
The battery will not fit! Not a chance!
The battery is smaller and thicker!
It touches the contacts, and you can start the phone, but there are a lot of gaps!
So, if you're headed to listen those "online claims", don't do it, you'll just throw away your money!
If this helped, please press the "THANKS" button!
So, on 4PDA forum, and other places, people was claiming that in Lenovo A850+ can be placed the Lenovo S660 battery! That would be great, I thought, since the S660 battery is bigger (3000mah) than the original is 2500mah and it would give more life to the device, so I bought one BL222 battery (S660 model battery) on ebay!
