Is there any way to get it to report the remaining time accurately? But I've seen it report 17 hours 46 minutes at 100% charge then 10 minutes later 2 hours 41 minutes remaining at 99% then a few minutes later up to 6 hours remaining. I'm aware from previous posts that immediately after charging to 100% mint tends to report ridiculously high run times so this isn't a major issue. The battery also reports high run time eg 17 hours immediately after being fully charged to 100% then drops suddenly. I've got Wifi turned off and just a wired connection. The screen brightness is 25% so I don't think it's that either. I've already installed TLP and ran recalibrate and haven't noticed a difference. Even accounting for normal brand exaggeration under 5 hours seems like there must be something wrong. Especially since the advertised run time is about 12 hours. On previous laptops I've dual booted with Mint and Windows I've noticed worse battery life when running Linux.Īlthough I haven't run Windows long enough on this Thinkpad to assess the battery life and compare directly but still this seems surprisingly low. I ran Windows a few times to configure some settings to make setting mint up easier. This is a single boot laptop Linux Mint 20.1 Cinnamon Thinkpad T15p. The battery drains in under 4-5 under hours even with light use eg email, text based webpages- no Youtube, videos etc.Ĭan someone help get the battery life to a decent amount? I got a new Thinkpad probably less than a month ago.
