I have charged my battery laptop to a 100% but after some time it drops to 93%

Is it doing this while on the charger?

 

You can check the battery to some extent using Powershell built into Windows 10. as follows:
1) Press Windows key + X
2) Click Powershell in the menu
3) Type powercfg /batteryreport

This will generate a report and if you scroll down, you will see Design Capacity and Full Charge Capacity ratings. If the Full Charge Capacity is less than 50% of the Design Capacity, it is faulty and needs to be replaced.

Also note the figure alongside the "Cycle Count". This tells how many times the battery has been fully recharged. A typical battery can handle around 500 charge cycles, but some will fail sooner than that.

The full charge and design capacity is the same. But why does it drop from 100 to 93 when its fully charged?

HP Recommended

The whole time you are using the laptop on battery, power is being drawn -- so it is going to drop.

 

IT would be nice if it dropped in a strictly linear fashion, say 1% every 30 minutes -- but it does not do that because at any one time, a mix of 50 or so services are running, some firing up as the Windows system determines, and these do not all use the same battery power.

 

So, the battery could drop 7% in just a few minutes and still be OK.  If it continued to drop at that rate, then it should be showing up as faulty in the testing.  If it is not, there is nothing we can do from here about that and you would have to consider replacing the battery.

I have tested the battery as well in HP Support Assistant. It says the battery is OK.

HP Recommended

It doesnt drop 7% every min. it drops a 2% or 1%

HP Recommended

ok if 50 or more services are running, do you know how to turn it off?
