What does the graph of stock laptop battery discharge time by decade look like?
I vaguely remember seeing a 20th century ad advertising the world's first 3 hour laptop battery and thinking wow that sucks. Sagittarian Milky Way (talk) 22:25, 22 June 2022 (UTC)
 * The lack of a reply so far may mean that no-one has previously had a reason to collect, collate and graph this information: you could be the first!
 * Websearching yields plenty of data pertaining to the date it was published, mainly intended as advice to purchasers (who would have little interest in the historical trend). Doubtless this could be researched for the information you seek. {The poster formerly known as 87.81.230.195} 90.201.73.76 (talk) 18:44, 24 June 2022 (UTC)
 * The Internet Wayback Archive would come in useful for this probably. 2603:7000:E43F:9867:34F5:A66F:A060:65F2 (talk) 01:02, 30 June 2022 (UTC)
