Chosen Solution

I recently replaced the battery on an iPad mini I bought off a friend. I am having the same problem as many of you in that the iPad is not registering that it is charging, and the common solution is to replace the FL7500 filter… however the filter is still present. Help please?

Replace the filter the filter acts as a “gas gauge” if it’s not going up it’s the filter just because it’s there doesn’t mean it’s good.
