New HP Omen 16.1 battery discharging at -3500ma on a fresh window on zero CPU/RAM/GPU usage

[hamzarr]

Bought a new HP Omen 16.1 laptop
battery has 19 battery cycles now

and it has 2 issues:

battery design capacity is 83wh and full charge capacity at 70wh 

It discharges at around -3500ma rate (it would not even last 2 hours at this rate)
It's a fresh new windows installation and CPU/RAM/GPU usage is literally close to nothing. No app running in background.

(it's a new laptop and even the seller replaced the new battery after I reported him issue and new battery is still doing the same in this laptop)

Hi @hamzarr, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 

Your HP Omen 16.1 is giving you battery blues, even with a fresh battery🔋? That's definitely a puzzle! 🧩Let's troubleshoot this power drain mystery.
 

Check Battery Report & Wear Level

Run the following command in Command Prompt (as administrator): powercfg /batteryreport

• Open the generated battery-report.html (usually in C:\Windows\System32) and check the Battery capacity history section.
• If the full charge capacity is consistently much lower than the design capacity (83Wh vs. 70Wh), your battery might already be degraded or miscalibrated.

Recalibrate the Battery

Since this is a new laptop, the battery controller may not be calibrated properly. Try recalibrating:

1. Fully charge the battery to 100% and keep it plugged in for 2 hours.
2. Unplug and discharge the battery completely until the laptop shuts down.
3. Leave it off for at least 3-5 hours.
4. Charge back to 100% without interruption.
   Check if the reported full charge capacity improves after this process.

Update BIOS & Firmware

• Go to HP Support → Download the latest BIOS update for your laptop.
• Check for battery firmware updates under HP Assistant or Windows Update.
• Also, reset BIOS to defaults after updating.

Check Background Processes & Power Plan

Even though you mentioned no background apps, check Task Manager → "Processes" & "Startup Apps" for hidden power-consuming apps.

Open Command Prompt (Admin) and run: powercfg /energy

This will generate a report of power-hungry processes.

In Power Options, set to Balanced or Power Saver mode and disable fast startup: powercfg -h off
 

Test in Safe Mode

Run the laptop in Safe Mode and check if the discharge rate remains the same. If it's lower in Safe Mode, then some driver/software in normal mode is consuming extra power.
 

I hope this helps. 

Take care and have a good day.
