sudden battery change

[stewarta13wsb]

Nothing knowingly changed on my usage (did download a slightly more colourful watch face but stopped using it and back to black) switched off S-Voice and disabled overnight notifications, don't use AOD, and battery is getting worse. 99% at 11.30pm last night and now at 8.20pm next day it's at 21%

Any suggestions? (UK model S3)

"You might also want to force a reboot by Holding in the Power Button. If something odd happened a reboot might clear it."

Sorted - not sure why but it fixed it for me
