It doesn't take long for lithium batteries to start losing their max charge. In practical terms you probably won't notice that 3% difference.
I just recycled one that was down to ~70% at max, but it was also ~4 years old. Oddly enough, I have one that's a few months older that still recharges to above 90%. And I switch between them every charge, so they were both used about the same amount. This just shows they wear out at different rates.
