2 X Controller Ps4 Rotti

Both have some sort of power problem when I try to charge them there's no amber light but I do get the flashing white light they will connect to my phone and then both disconnect. if I try plugging them into a laptop they both say USB not recognized I don't really know what's going on with them to tell the truth sold for spares and repairs both left thumbsticks will need replacing soon
