Battery

[KA4D3N]

Hi I have found that recently my battery has gone from 100% at 6:15 am (UK time) to at 7:50 am with me only using it for 30mins at most and having to charge it at school 

Does anyone know why this may be happening 

And just to clarify I have run the device tests on the device care app

You might want to clarify what % your battery has dropped to.

@KA4D3N: If you head to Settings > Battery and device care > Battery > Tap on the usage graph, can you see any apps or features listed in the breakdown at the bottom of the screen that might account for your battery drainage? Also, please head to the Samsung Members app > Press and hold on the app icon > Diagnostics > Phone diagnostics > Battery status, and check the 'Life' summary to see if this flags any issues.
