Acer Nitro V 15 ANV15-51- Charging and Battery Problems

I own an Acer Nitro V15 ANV15-51 equipped with an Intel Core i9-13900H processor, 32GB RAM, 1TB SSD, and an NVIDIA GeForce RTX 4060 GPU.

During demanding gaming sessions, I've observed that the battery gradually discharges even while the laptop is plugged in using the original 135W charger. This is concerning, as I expected the device to maintain its charge or at least not consume battery power during intensive use when connected to an external power source.

It seems that during high-performance scenarios, the power consumption exceeds the 135W provided by the charger, causing the system to draw additional power from the battery.

Is this behavior typical for this model? Should I consider acquiring a charger with a higher wattage (such as 180W or 230W)? If so, could someone recommend the appropriate and compatible charger model for the Acer Nitro V15 ANV15-51?

Thank you in advance for any insights or recommendations you can provide.

This issue is common in gaming laptops. It's normal for a laptop's battery to discharge during demanding gaming sessions, even while plugged in. This is because the laptop may be drawing more power than the charger can supply, requiring the battery to supplement the power.

During Hybrid Power Mode doing demanding tasks, the laptop may draw power from both the charger and the battery to meet high power demands. The 135W charger might not be sufficient to sustain peak performance. Consider upgrading to a higher-wattage charger if available for your model.

The battery acts as a buffer, providing extra power when needed to maintain performance, even when the charger can't supply enough. Reduce power consumption by lowering graphics settings or enabling performance modes that balance power usage. Ensure your battery is in good condition. Use Acer Care Center or third-party tools to check its health.

Overheating can increase power draw. Clean vents, use a cooling pad, and ensure proper airflow.

To generate a battery health report, Press Windows + R, type cmd, and hit Enter. Type powercfg /batteryreport and press Enter. This will create a battery report in your user folder. Open the file in a web browser to check battery health, capacity, and usage statistics.

Thank you for your suggestions, Sharanji.

I've implemented all the recommended steps you mentioned earlier, including lowering graphics settings, enabling high-performance modes, and utilizing a powerful cooling pad. Despite these efforts, the battery continues to drain during intensive gaming sessions, even when the laptop is connected to the original 135W charger.

Upon further research, I've discovered that during demanding tasks, my Acer Nitro V15 ANV15-51 can consume up to 140W of power. Given that the original charger provides only 135W, it's understandable that the system might draw additional power from the battery to meet peak performance demands.

Considering this, I'm contemplating upgrading to a higher-wattage charger, such as a 180W model, to ensure the laptop receives sufficient power without relying on the battery. However, I'm still uncertain if that would resolve the issue.

Could you, or anyone else reading this, advise me on whether a 180W charger (or higher) would effectively address the battery draining problem with the Acer Nitro V15 ANV15-51?

I appreciate any insights or recommendations you can provide.

Hi, update BIOS with version 1.25 dated 2025/03/17 and check for optional updates as Microsoft, Acer and Intel recently released firmware to mitigate excessive battery drainage. Update Nitro Sense. Users with similar issues reported that a 180W power adapter did not observe less battery drainage, so I recommend trying to approach your problem with software rather than hardware. Also reduce the background apps continuously using your recourses with telemetry (Cloud traffic), make sure in Task Manager-Processes that these apps don't exceed 80, uninstall programs you don't use, including the Startup apps. Use Best Power Efficiency and set the fan speed to Auto, turn off Turbo Boost in Nitro Sense as it seems to be inconsistent: Some users have noticed that it appears randomly and then disappears after a restart.

Upgrading your Acer Nitro V15 to a 180-watt charger might not be ideal. The laptop is designed to work with a 130-watt adapter, and using a higher-wattage charger could potentially cause compatibility issues or damage the internal components. It's always best to stick to the manufacturer's recommendations for power adapters.
You might want to explore other options, such as optimizing your laptop's settings or upgrading hardware components like RAM or storage.

I've check all the stuff you told me to update and everything was up to date apart from BIOS… I checked my version and I have the

V1.21 from 25/10/2024

I will try to update it and see if it fixes my issue, but I'm not that confident about it honestely.

Hi, recent BIOS updates with Intel and Windows updates/patches will improve that excessive battery drainage caused by Modern Standby in Windows11 24H2. Also check the number of background programs running in Task Manager-Processes.

Sorry to bother you about this but… I'm quite a dumb fella when it comes to computers… how do I check the number of the background programs running in Task Manager-Processes, and what can I do about it exactly? I'm not sure what to do.

Hi, no problem, this is from my Asus Vivobook OLED laptop running on W11 24H2:

Click on the Processes column header and it will rearrange the processes list like above, I never get more than 70 background programs. To uninstall the pre-installed stuff, bloatware and trial versions you don't use, open Windows Add and remove programs and click on the 3 dots at the end to uninstall.
