I got a C5 from Amazon this week and I noticed that I can't use it to charge my phone (Moto X 2014) if the amp's battery indicator has only 2 lights on.
It works only when all 3 lights are on(fully charged), which lasts for ~30min and then it drops to 2 lights at which point the phone stops charging (every few seconds the phone switches between charging and not charging, as if there is a bad contact). I tried multiple cables just to make sure it's not a bad cable.
Did anyone else experience this? Is this behavior normal or did I get a faulty unit? Other than this the amp seems to work just fine.
Thanks.
To protect the C5 battery, we have set a safety capacity level, and when C5 has dropped below the specific battery capacity, it will stop the charging external device feature to reserve the battery for C5. From what you have described, your C5 has dropped below the safety capacity level when the power indicator drop from 3 LED to 2 LED
You just bought a C5 from Amazon this week? I suggest you use it regularly for a while, hopefully after several charge/discharge cycle, the battery will be in better condition and the situation will be improved. The problem is when a Lithium is stored (unused) for a long period of them, the efficient of the battery is at low point, and it will recover after extended usage.
