Persistent Battery Life Issue on Arch Linux with Razer Blade 14 (RZ09-

mrmetaverse · 2024-04-29 22:15:03

Hey all! I have been using Arch for a few years now, and can't seem to figure out what happened here. My laptop has both an integrated GPU (AMD CPU) and a NVIDIA 4070m. I am using hyprland, and have been able to generally get about 4-8 hours battery.

Recently, I can only get about 2 hours on a full charge. It has been over the last week, and I am not sure what changed. I have tried everything I can think of, from tweaking TLP, to powertop, and many others. I am wondering if I need to wipe and reinstall...

Summary:
I am experiencing persistent battery life issues on my Razer Blade 14 (RZ09-0482) laptop running Arch Linux. Despite multiple troubleshooting attempts and optimizations, I am unable to achieve more than 1.5 to 2 hours of battery life on a full charge.

**Steps Taken:**
1. **Power Management Software:**
- Installed and configured TLP (1.6.1) to optimize power settings.
- Utilized TLP-stat and powertop for monitoring and tuning power usage.
- Applied various power-saving measures recommended by TLP.

2. **Kernel and Hardware Settings:**
- Updated to Kernel 6.8.7-arch1-2 for potential improvements.
- Checked and adjusted CPU frequency scaling and governor settings.
- Verified that hardware components are properly managed for power efficiency.

3. **Graphics Card Optimization:**
- Configured NVIDIA GPU settings using nvidia-settings and xorg.conf.d adjustments.
- Set PowerMizer mode to adaptive and applied additional power management options.

4. **System Services and Background Processes:**
- Reviewed and stopped unnecessary system services and background processes to reduce power consumption.
- Disabled webcam and other peripherals not in use to minimize power draw.

5. **Battery and Hardware Health:**
- Monitored battery health and charging behavior to ensure proper functioning.
- Checked hardware components for any anomalies impacting power consumption.

Despite these efforts, the laptop continues to exhibit poor battery life, with only 1.5 to 2 hours of usage on a full charge under normal workload conditions. This significantly hampers the portability and usability of the device, especially when working remotely or in areas without easy access to power outlets.

**Expected Outcome:**
I expect that with the optimizations and configurations made, the battery life should be significantly improved, allowing for at least 4-6 hours of usage on a full charge, as typically seen with similar laptops running Linux distributions.

**Additional Information:**
- Laptop Model: Razer Blade 14 (RZ09-0482)
- BIOS Version: 1.06
- OS: Arch Linux
- Kernel: 6.8.7-arch1-2
- Power Management Tools Used: TLP, powertop
- Graphics Card: NVIDIA GeForce RTX 4070 Laptop GPU

**Request for Assistance:**
I kindly request further investigation and support to identify any underlying issues or misconfigurations that may be causing the battery life problem. Any guidance or solutions to improve battery efficiency on this system running Arch Linux would be greatly appreciated.

Thank you for any help...

Best,

Jesse

at least 4-6 hours of usage on a full charge, as typically seen with similar laptops running Linux distributions

and a healthy battery…

tail /sys/class/power_supply/BAT0/*

What does powertop suggest as current/average draw and what are the major consumers?

mrmetaverse · 2024-05-02 15:50:12

See thats the thing... even at 0% screen usage, the battery life doesn't change at all. I can't tell if it is still consuming all of that power.

The battery reports a discharge rate of 32.5 W
The energy consumed was 586 J
The estimated remaining time is 1 hours, 58 minutes

Interesting... the battery life is the same at 100% brightness as it is 0%

The battery reports a discharge rate of 32.5 W

That's probably not correct unless that notebook is really. REALLY old and/or

 24.2 W      0.0%                      Device         Display backlight

used to illuminate the neighbourhood (I use a beamer with less power to illuminate a rather big garden, your notebook panel doesn't draw 24.2W - you turn blind when you look at that)

Is the battery life concern based on "I let the system run for x hours and it took this long until it shut down" or on what the acpi reports as estimated runtime?

 2.80 W    100.0%                      Device         USB device: Integrated RGB Camera (Azurewave)

I don't really buy that number either - is the webcam even active?

mrmetaverse · 2024-05-02 19:18:03

I disabled the webcam, and still same issues. Maybe I nuke it and start over, wouldn't be the first time... Its a 2023 Razer 14 (AMD CPU and integrated GPU, NVIDIA 4070)

Hyprland is wayland, and I used to have working power profiles, but now nothing works. No bbswitch, bumblebee.

I could try a fresh install, and if the battery is still butt, I can try another OS/kernel.

The battery health is at 89%, which isn't great for less than a year, maybe I can replace that.

seth · 2024-05-02 19:24:19

You did understand that the reported power draw of the display is complete nonsense?
I don't think the ACPI report is correct and I'd certainly not trust it
In that case no re-installation and no other kernel will help you, that's a BIOS/UEFI problem.

I used to have working power profiles, but now nothing works. No bbswitch, bumblebee.

This will report the GPU to be active if you (also) run nvidia-smi, so don't.

The battery health is at 89%

89% of what? Aggregating the condition in a single "health" percentage is meaningless.

thanks for this...

New updates came in, and my battery appears to be normal now (seeing 4.5-11.5 hours depending on the use)

New powertop:
