Did this happened after the update?
Sometimes all it needs is a bit of calibration.
Have you tried to completely drain the battery before charging it again?
After the update my battery seemed to run out quicker than quick, however I didn’t had a charger one evening and 1% held for 3(!!!) Hours of heavy use.
Try to completely drain your battery (so it would actually shut down) and charge it back to 100% using wired charger, then repeat and you should have it back in order.
Hope that helps.
