High Battery Drain During Suspend on elementary OS 8 (ASUS ROG Zephyrus G15)

### What Happened?

# Battery Consumption During Suspend – Technical Report

**elementary OS 8 (Circe)**

---

## 1. Purpose of this report

This report documents a single battery consumption test performed during suspend mode on elementary OS 8.
The goal is not to report a bug or criticize the system, but to clarify whether the observed behavior is expected given the operating system and hardware characteristics.

> This test was performed once, only to gain a general understanding of suspend power usage. It does not represent my normal daily usage pattern.

---

## 2. Test scenario description

- **Test type:** Single, manual test
- **Period:** Overnight, approximately from 01:00 to 07:00
- **Power source:** Battery only
- **Laptop state:** Lid closed
- **User activity:** None
- **Applications running:** None intentionally opened
- **Purpose:** Observe battery drain during suspend over several hours

*A battery usage graph screenshot from this period is attached.*

---

## 3. Observed behavior

- Battery level dropped by approximately **8–12%** over ~6 hours of suspend.
- The discharge appears **continuous rather than flat** during the suspend interval.
- This behavior was observed only once and has not been tested repeatedly.

- **Distribution:** elementary OS
- **Version:** elementary OS 8
- **Codename:** Circe
- **Base:** Ubuntu 24.04 LTS
- **Kernel: 6.14.0-37-generic

## 7. Battery information (after resume)

- **Battery model:** ASUS A32-K55
- **Design capacity:** 90.0 Wh
- **Current full capacity:** ~69.1 Wh
- **Battery health:** ~76.7%
- **State:** Discharging
- **Observed discharge rate after resume:** ~22–35 W

## 8. Notes and considerations

- This was a single test, not a long-term measurement.
- The suspend interval used is not representative of my normal daily usage.
- The goal is only to understand if this consumption level during suspend aligns with what elementary OS currently offers on this type of hardware.
- The report is shared in good faith and with appreciation for the elementary OS project.

### Steps to Reproduce

This was a single, one-time test, done only to clarify a personal doubt. I cannot say whether the behavior always repeats in the same way, as this is not representative of my normal daily usage.

### Expected Behavior

I would like to share a battery consumption analysis I did on my notebook running elementary OS 8, purely as a question for better understanding, and not as a complaint or criticism.

This was a single, one-time test, done only to clarify a personal doubt. I cannot say whether the behavior always repeats in the same way, as this is not representative of my normal daily usage.

During this specific test, I left the system in suspend mode overnight (approximately from 01:00 to 07:00), running only on battery, with the laptop lid closed and with no applications or programs open, and no user activity during that period. The observed battery drop was around 8–12% over this interval.

My intention is simply to understand whether this level of battery consumption during suspend is considered expected behavior for elementary OS on my hardware scenario, or if I might be misinterpreting the results from a user perspective.

To provide proper context, I have attached a technical report containing detailed information about hardware, firmware, kernel, and power management, along with a battery usage graph from this test.

I’m sharing this because I genuinely want elementary OS to have the best performance possible among Linux distributions. It is the system I use daily, one I really enjoy, and I’m happy to contribute in any way I can to help the project continue improving.

Thank you for your time and for the work you do on elementary OS.
