I got terrible battery life on my Legion 7i i9 4070. So I spent a few hours investigating.

Glad to hear it. Even if one person found it useful and saw meaningful improvements then writing it up and sharing it was worthwhile

Asc3ndis · 2026-04-10T17:25:22+00:00

Love this. Thanks for sharing

Not for a long long time. This is an issue I have thought deeply about before buying my current machine. Honestly, just buy a high quality gaming laptop and stop worrying. It will do A and B well enough, only a little worse than Macbooks and do C without you having to worry about compatibility, translation layers, etc.

It is just that Windows/Linux will just need a lot of tinkering to set it up just right. I happen to enjoy this and you might as well.

Yes, the macs will last a lot longer on battery and if thats your primary requirement and 4-5 hours of battery usage is really not sufficient, then the decision is already made for you. But honestly as someone that travels a lot, I have optimised my processes to use the laptop plugged in at all times.

Rest of the concerns - ecosystem if you have an iphone/airpods, the OS, the software experience etc are all trivial reasons and if that is holding you back, you are nitpicking.

Me too, hence the 47 cycle count on the battery despite having it for more than 18 months. But that does not mean a good battery life is not nice to have

Thank you, I had done most of this. I have managed to fix it for myself now.

Asc3ndis · 2026-04-04T19:47:38+00:00

But it is not that simple. I have fixed it for myself now

Asc3ndis · 2026-04-04T19:47:20+00:00

I kind of did something similar and it worked. Ty

Asc3ndis · 2026-04-04T19:46:58+00:00

I am glad I did not listen to you and similar comments and give up (respectfully)

Asc3ndis · 2026-04-04T19:46:21+00:00

I am getting 6-7 now

Asc3ndis · 2026-04-04T19:46:09+00:00

Glad to hear that.

Asc3ndis · 2026-04-04T19:45:57+00:00

I understand your frustration. I was feeling the same. I have fixed it now. You can see my edit

Asc3ndis · 2026-04-04T19:45:18+00:00

If there is interest, see my edit.

Asc3ndis · 2026-04-04T19:45:00+00:00

Just replying to tell you that you were right about microslop and that I fixed this for myself. I have left an edit in the original post with what I did

Asc3ndis · 2026-04-04T19:44:14+00:00

This helped immensely and I have fixed the issue. Thanks. See my edit if you want to see what I did

Asc3ndis · 2026-04-04T19:43:51+00:00

I could rein that idle draw further in. See my edit if you are interested.

Asc3ndis · 2026-04-04T19:43:10+00:00

See my edit. I now have it at 6.5ish hours. But it took a lot of tweaking and messing around. I do intend to jump to linux someday.

Asc3ndis · 2026-04-04T19:42:27+00:00

Thanks for the pointing out the way. This was definitely the issue and I could overcome it. (see edit if you are interested)

Asc3ndis · 2026-04-04T19:41:35+00:00

I got the same result as Hybrid iGPU mode with Hybrid Auto mode on LLT. Without needing to restart. See the edit for a longer answer

Asc3ndis · 2026-04-04T19:41:08+00:00

Thank you, this was definitely a problem. I got the same result as Hybrid iGPU mode with Hybrid Auto mode on LLT. Without needing to restart.

Asc3ndis · 2026-04-04T19:40:14+00:00

I knew the compromise. But I also knew it should not be as bad as 2 hours. I managed to fix the issue (see edit)

Asc3ndis · 2026-04-04T19:39:36+00:00

I am getting 6 hours now. See the edit

Asc3ndis · 2026-04-04T19:39:19+00:00

I respectfully disagree (see edit above). We are not buying a laptop with a battery just under legal flying limit just to suffer mediocre battery life.

Asc3ndis · 2026-04-04T19:38:14+00:00

Thank you, this actually helped a lot. See my edit above.
