To end his frustration, one Flare user (Leshrac Hunter) has modified a Samsung 2,100 mAh battery terminals to fit the Flare. See video below:
He said that he never encountered any problem after using the battery for several hours. If the user gives further updates, I'll post it here.
Update:
- It's a class A Samsung Galaxy S III Battery
New: Cherry Mobile Flare using 2,200mAh battery for LG P970 Optimus Black (No Need to Modify!)
