New Thinkpad T490 Horrible Battery Life

2019-07-27, 23:41 PM

 I recently received my new Thinkpad T490, but it appears that the battery life is absolutely horrible (<3 hours on a full charge). Is this simply because of my configuration/usage, or is there something I'm missing that can help improve my battery life?

 

When I received the computer, I upgraded the RAM and SSD and re-installed a stock version of Windows 10 Pro.

 

Lenovo ThinkPad T490

  • Intel Core i7-8565U Processor
  • 24GB (8GB Internal + 16GB SODIMM, added post-production) RAM
  • nVIDIA MX250 2GB dGPU
  • 1TB Samsung 970 Evo Plus NVMe SSD (added post-production)
  • WQHD IPS Glossy Panel (usually running at 75%-100% brightness)
  • Fibocom L850-GL LTE WWAN Chip

 

I'm mainly spending time doing light web browsing, an occasional YouTube video, etc. Nothing too CPU-intensive. The battery has, so far, been through 3-4 charge cycles already. CPU running at about 10-15% (1-2.5GHz) on average.

Having the same exact issue on Win10 1903.

Getting less than 3 hours of run time from a full battery.

I have the same thing on Linux (tried different distributions), even with disabled nvidia; latest firmware updates applied ... fully charged shows a maximum of 3:20, going down rapidly, now I'm at 87% with 2:20 … please Lenovo listen and give feedback, thanks.

I ended up purchasing a USB-C PD power bank that I carry around with my laptop. With a full laptop charge + full USB-C power bank charge, I can get about 6-8 hours of total use out of my laptop.

 

Obviously not optimal, but I already carry a bag almost everywhere I carry my laptop and the extra weight isn't too much.

Windows 10 Battery Settings should show you which apps are affecting battery life, and Task Manager can show you CPU usage. I doubt a rogue app is the issue, but to get the most from your PC battery it is worth looking there.
