T480 Battery Drains Quickly

2019-07-31, 0:16 AM

Hello everyone,

 

I just bought a Thinkpad T480 and the battery seems to be depleting very quickly. The computer, using both batteries, has a lifespan of 6-8 hours. At this point, I don't use the computer for purposes other than school work, web browsing, and occasional videos. Computer is running on default settings.

 

I'm wondering if others have similar issues with brand new t480s and their batteries.

 

Any tips to improve battery life would be greatly appreciated.

 

Thank you.

I also have the same Issue with my Lenovi T480. It was working fine before but then all of a sudden it started draining Fast and the battery doesn't even charge to 100%

Same thing here. Bought this T480 in June of 2018. Both batteries easily yielding 12+ hours. Now down to 3-4 hours, max. I've more or less only used the machine as a thin client to operate a Win10 VM in the cloud over WLAN and WWAN (the VM does all the heavy lifting), so rarely does the fan even spin up. In layman's terms: I've never really stressed this machine, ever. I've upgraded Windows 10 Pro from 1809 to 1903 over that time, plus have always been on latest drivers from Lenovo.

 

A look at Vantage shows internal battery is down to 16.5Wh from the original 23.94Wh (220 cycles), external down to 33.32Wh from the original 71Wh design capacity (318 cycles). Vantage is telling me the external, at ~40% of original capacity, is in "Good" condition. Seriously?!?! The same thing happened to my Gen1 X1 Yoga, in just about the same amount of time. What gives Lenovo? Is it poor power management by your hardware/firmware/software, LG's fault for making crappy cells, or a combination of both?

 

Anyone else experience this? I not super excited to have to purchase two new batteries every 12 months, just to stay within a reasonable amount of original capacity, but if that's what it takes, then so be it. Awful.

Thanks for chiming in, Keith.

 

Per that article, disabling Connected Stanby may help discharge speed, but even so, as far as the point of view of the batteries goes, that shouldn't be a huge contributing factor to the kind of excessive wear that I'm observing, should it?

 

For comparison, I have a 7 year-old T420 with only a single battery, the original extended model, which has gone through at least as many cycles, but is in way better condition when cosidering wear over time, and has been running the same sub-versions of Windows 10 for the latter half of its life. Isn't it ironic that a T-series that's 6 years older and technically unsupported by Lenovo for most of those Windows 10 versions, has been able to prolong its battery way more effectively than this T480 or my Gen1 X1 Yoga. Something has to be amiss on Lenovo's side of things... no?

 

I appreciate any further help you or anyone else can lend. And apart from this and a flaky WWAN card, the T480 has been a pretty good machine otherwise.
