I've recently put CyanogenMod CM10.2.1-yuga on my Xperia Z and I've noticed the NFC server is using an insane amount of the battery.

Even after disabling the service in the App section, the service is still running and continues to drain battery:

And the NFC section of my settings is greyed out

Any idea of what's going on or how to diagnose this further?

  • Try Calibrating your battery or try freezing nfc.apk and tag.apk. Did you post this in Cyanogenmod forum?

You can try the following:

1.Try Calibrating your battery ( few says it is necessary to calibrate your phone after rom installation)

  • Charge phone to 100%

  • Boot in to recovery

  • Wipe battery stats

  • Reboot and drain the battery completely ( by playing or media or normal usage)

  • After complete drain recharge the phone again to 100%

2.Try freezing or renaming or removing nfc.apk and tag.apk (Instead of removing the apk just try renaming them like nfc.apk.bak)
