I ran the diagnostic test on IBackupnow and got the following results. The battery itself does not seem to be too bad based on DesignCapacity = 2855 FullChargeCapacity = 2500 Based on these two numbers my battery is operating at 87%. The disturbing number that was shown is the CycleCount = 792 I've had my 6Plus since it was released, is it time for a battery replacement? I have seen other stats posted but nothing with a cycle count as high as mine. Phone charges erratically, sometimes the unit will charge overnight and max out at 74%, other times it charges slower than that or will go up to 100%. I have cleaned out the lightning port and everything else is working fine.
