Did the display show 100%, or just 92%? I'm assuming charging was complete? When was the last time you charged to 100%? Reason I ask is that 100% is 100% of the module that can take the least amount of charge. If you haven't charged to 93% or more in a while, the balance circuits won't have kicked in and you may have an out of balance battery. If so, this will correct itself now that you did a 100% charge. It may take a few weeks to do so.
