[Legion 7-16ACHg6] Battery Draining Fast

2021-07-15, 1:28 AM

Hi, just had my Legion 7 which is an awesome beast!

 

The only problem I have is battery draining fast at a rate of 1% per minute. Currently it can only last around 3 hrs after a full charge. I have tried to search solutions online such as uninstall Corsair iCUE and reset power setting by pressing power button for 60s when it is switched off and unplugged. However, the issue persists.

 

Is there any other methods I can try to resolve this issue?

Hey depends on what your usage is. I am using it for work purpose. Turning on battery saver, switch it to 60Hz and go to hybdrid mode with quiet mode. This helps to extend the battery to 5-6 hours depending on the usage. This case is for mainly chrome, video call usage.

 

But if you are gaming and going to max out all the settings, best is to use plug the laptop to wall power socket.

Hello @JC_H,

 

Welcome to the Community Forums.

 

Kindly try switching from Discrete mode to hybrid mode for improved battery life.

Usually gaming laptops have bad battery life because of the packed specifications.

Hope this helps.
Regards,

Re:[Legion 7-16ACHg6] Battery Draining Fast

Hi!

I am also experiencing a mysterious battery drain issue. I got my Legion 7 (5800H, 3080) without OS so had to install drivers and everything myself. iCUE is not installed at all so it can't be that. Have the latest BIOS from Lenovo support page.

 

I have the hybrid mode engaged and BIOS is set to dynamic mode. Still, the dGPU is draining a constant 25-30w when in idle, even though task manager and Nvidia control panel are showing that dGPU is not being used at all. The battery life is around 2:30h when laptop is idling! Please help.

 

Have looked into all battery life extension tricks, like 60hz screen and dimmed etc. Can't get the 3080 to not draw power when not in use..

Is it possible to have it make the switch from 60 to 165 automatically when I disconnect it, cause I don't game at all unless I'm plugged in, but I use it for work is just data entry and chrome tabs, i just switched it over to 60, and im hoping this fixes it, ive already done everything else here, i was expecting at least 4 hours for this use case and cant get it about 2maybe 2.5 tops

Hi, please install HWINFO64 and check sensors. There it should show detailed specs on what is draining how much power and what the total battery drain is.

I presume you have Hybrid mode engaged?

 

I don't think you can swap screen hz automatically. But the 165hz screen alone shouldn't drain the battery all that much.. maybe 5-10% more or something, not what you're reporting.
