Battery capacity decreasing...

[Nagesh3]

I bought laptop 2 months ago ,, After fully charging it to 100 it Directly jumps to 95 (without showing 99,98,--,96) after few minutes...

and also the battery capacity has decreased from 52Wh to 48 Wh.. (3 cell battery)

(Checked the battery report from cmd - powercfg/batteryreport)... 

My friend had bought laptop (of lower specification)  2 years ago and his battery capacity is perfectly fine (same as first time i.e., 35 Wh.. )..

But in my laptop,,

For about 4Wh decreased in just 2 months 

Any problem with my laptop? 

How to solve this issue?

You're basically comparing "apples to oranges"  in that the two laptops most likely have very different battery technology -- so they WOULD behave differently.  The newest, lightweight laptops use the same batteries as cell phones and they behave the same way -- with sudden drops to 95% or 943% and then a stead decrease over time.

There's nothing that can be done about that -- it's how the new batteries behave.

So u are saying that all light-weight laptop's battery drops from 100 to 95...

What about its capacity decrese by 4000 mWh in 2 months?..

What I said is that the sudden drop is typical of the new batteries and can not be avoided.

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.

Yea , I've already checked that in cmd ,, and full charge capacity is 4000mWh less than designed capacity ... So i asked here that - Is it common  in just 2 months capacity decreses ??
