Battery Life flop in a week

[Umair679]

Hello Sir,

I bought my laptop 2 months ago, and the battery was very fine and i was able to use my laptop about 6 hours after 100% charging, and the the laptop charged full in 2 and a half hours. Now, about a week ago my laptops charged full (100%) in 1 hour and 15 minutes and when I start to use it it only run approximately less than 3 hours. 

I am really worried what I do.  before a week when i click on the battery icon in the taskbar it shows 7 hours or 6 hours remaining. Now it shows 3 hours remaining. What is the matter plz guide me.

Hi! @Umair679, Thank you for visiting the HP Forums! A great place where you can find solutions for your issues with help from the community!

I understand you have battery issues with your laptop.

Don't worry I'll try to help you out.

Did you make any software or hardware changes on your laptop?

Please provide the product number of your PC to assist you better.

As you mentioned the battery life dropped from 7 hours to 3 hours in a week.

A battery is a consumable part the life of the battery keeps decreasing every day when you charge your laptop.
 
However, Try updating BIOS on your PC and check if it helps.

Link to update the BIOS.

Also, update other drivers on your PC using HP support assistant.

Refer this article to know more information about using HP support assistant.

Battery cycle life is the total number of discharge-charge cycles (Figure 1) a battery yields before it can no longer hold a useful amount of charge. Estimating the cycle life of a rechargeable Li-Ion battery is difficult because cycle life is affected by the average operating temperature of the battery and its energy discharge rate.
Basically, higher temperatures and higher energy discharge rates decrease battery cycle life. The operating temperature of the battery depends on the air temperature as well as the heat generated by the notebook itself and by its immediate environment, such as a docking station. The energy discharge (drainage) rate depends on the type of applications running on the notebook and by its power management settings.
For example, running compute-intensive applications such as CAD, gaming, and DVD movies drains the battery faster and decreases its cycle life more than running word processing applications.
