T480 batteries drain too quickly and last only about one hour

2019-03-05, 6:16 AM

I bought my T480 four months ago and I was always using it with connecting to the power source. I'm rarely using it with the batteries but when I'm on it, it would only last about one hour, sometimes a little over one hour. Considering it's still new, I'm really fed up with the battery performance. Mostly, I only run chrome, vmware workstations and just normal browsing stuff. I don't also have much background apps. Both batteries are shown as good condition in Lenovo Vantage app. Do you guys have any idea? Thanks.

Is it normal that design capacity and full charge capacity is about 300mAh different?? I have attached screen shots.

Hi, I understand your frustration with slow or no answers on this forum..

 

I think your battery is somewhat faulty actaully. My internal "Main Battery" has 24 Wh design capacity and 25.22 Wh full charge capacity (so more than the design capacity...maybe this is normal). The cycle count is 24, so not so far from yours.

Anyway, the juice of my internal battery was actually a bit underwhelming, but I still can get around 3-4 hours with it, depending on workload. So your 1 hour indicates a faulty battery. It could be the battery, or it could be that you have some load on the machine that you are not aware of. What does Windows Task Manager say? Open with pressing Ctrl+Shift+Esc, click on Performance tab and check CPU usage.

The thing is, I also have the 72 Wh removable battery which of course bumps up the total battery time to a very respectable ~15 hours. So the internal battery "quickly" drains then the removable kicks in.

Thanks for your reply. I only have normal processes in the background. I managed to run a battery gauge reset on both batteries last week. Now the laptop stays up to 4hrs, but still I think they're faulty as you mentioned. I have a lot of things to do on my laptop. I hope I will hit the service center soon.
