battery life/drain issues/BIOS

[NateMarcroft]

This computer (I've run the battery health check it's at 80%) but I only get about 2 hours maximum with all power saving settings enabled. Aside from that I'd like to leave it charging overnight but I can't find a setting anywhere that would enable me to stop charging at around 80%? Also I've done some research into resolving errors and some of them seem fixable with an older BIOS, (advanced settings unlocked) and since my warranty has expired even if I wanted to (I don't) I wouldn't hold HP accountable for any instability caused by messing with my settings.

Hi @NateMarcroft,

Welcome to the HP Support Community! 

Thanks for reaching out about your query regarding laptop's battery!  

We're thrilled to have the opportunity to assist you and provide a solution.

Since your battery health is at 80%, it’s expected to have reduced capacity. However, to extend battery life, try these:

• Reduce screen brightness (50% or lower).
• Turn off background apps (Settings → Apps → Startup & Background Apps).
• Set Windows to Battery Saver mode (Settings → System → Power & Battery).
• Undervolt the CPU (Using software like ThrottleStop or Intel XTU – can improve efficiency).
• Disable Turbo Boost (reduces power draw but may affect performance).

Setting Charging Limit to 80%

HP does not provide an in-built charge limit option like some other brands (e.g., Lenovo, Asus). However, you can try:

Check HP BIOS Settings

• Restart and enter BIOS (Press F10 during boot).
• Look for "Battery Charge Limit" or "Adaptive Charging" (might not be available).

Use Third-Party Software
If the BIOS doesn't have this option, try a third-party tool like:

• Battery Limiter (Prevents charging past a set percentage).
• Notebook FanControl & Battery Manager (Advanced power control).

Let me know how it goes.

Hi @Kurol_Kenshl
I have already enabled all the possible power saving settings on my laptop. ( The battery capacity is at 60watt hours and if my power tracker is accurate it should be lasting at least 6 hours.) With an idle draw of ~6watts if I disable my dGPU. I have the HP battery lifespan option enabled but it does not let me cap charging. The reason I asked for a bios rollback is so I can have access to my advanced bios. Without advanced bios I cannot undervolt the cpu like I was hoping to (I already have throttlestop)  I have watched extensive guides on saving power and I have done everything short of modifying my bios image and physical modifications. I'm sure you guys still have the older bios' files stored somewhere and I just need access to those. Also for reference my 6watt idle draw is high compared to most users. It seems most of the people with similar issues all have the hp victus series indicating manufacturer error with something.Also the 6w idle draw is on a good day. On Hardware Info it said my computer was discharging at a rate of ~30,000 mW idling

Hi @NateMarcroft,

Thank you for the response.

Could you please try running the battery calibration tool in the HP Support Assistant?

Also, even with dGPU disabled, check for CPU-hogging apps using Task Manager (Ctrl + Shift + Esc) or powercfg /energy in CMD.

Let me know how it goes.
