So I recently ordered the Mugen Power 1950 slim extended battery for the phone with the name to long to type. It came with battery break in instructions. Charge it for 8-12 hours uninterrupted the first 5 times from the wall charger, running it down to 10 to 15% percent between charges and never allowing it to hit zero charge during that time. I thought Li-Ion batteries didn't have the memory problem. Do we really need to break them in? I plan on following the instructions but it just seems odd.
