.............New Lithium Ion batteries must be FULLY CHARGED and FULLY DISCHARGED 2 to 3 times, before being FULLY CONDITIONED. Please remember that a new Lithium-Ion battery's full performance and longevity is only achieved after 2 to 3 complete charge and discharge cycles. After you go through 2 to 3 cycles, you'll never have to condition your battery again! All talk and standby times are approximate, depending upon carrier's network settings, signal strength, and features selected.
