Battery life/Calibration

[Geordieboy]

Hi.

Does anyone know if there's a way to check the Battery, to see if it's charging/discharging correctly. Like an app or diagnostic program? 

I've always had bad battery drain, but now it drains relatively quick and charges from 0-50 in about 20 minutes. 

Is this normal charge time, as I thought it was slower than that? 

Does anyone else have the same issue?

Well the built in battery monitor in device care will show you graphically how your device is charging and discharging and show you which apps are drawing power.

For checking charge current when charging and discharge current when in use, i use an app called Ampere.

@Geordieboy: Further to the advice offered by @Shazzkid please head to Settings > Battery and Device Care > Battery, and tap on the graph to get a breakdown of your usage. You can also open the Samsung Members app > Get Help > Interactive Checks > Battery to run a health check.

Thanks. I know these steps already. They show battery is good.
What I'm asking, which seems to have been misunderstood slightly.
Is there any way to see if the battery needs calibrating (so wipe all knowledge of the battery percentage/charge level).
