Excessive battery drainage on my HP Pavillion-15ce 3006tx

[Rammit]

It has just been 2 months since I bought my new laptop. Initially, it was working fine but from the past 2-3 days the battery has been draining out excessively. Every day I switched off the laptop when it had been charged 100%, but when I tried switching it on again later in the day, the battery had been completely drained out. Do I need to take it to a service centre or can the issue be resolved at home?

Thank you.

While some battery drainage is expected in Windows 10 due to Fast Startup, you should not be seeing this amount of power drop in such a short period of time.

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.
