I replaced the battery in mine. Unlike big tech, I believe in repairing old devices. Something Amazon have not considered is how many of these old devices are used as companion devices for other high end kindle owners. I have a scribe and old paperwhite and use them interchangably, with cloud sync of reading position etc, which won't be possible after 20 may.

My paper white is about 7/8 years old, and is still holding up fine though the battery is noticeably degraded - charging it approximately once a week now.

I was also having a play with a demo model of the latest one in a store and the page turn speed is much much better, which is tempting me to upgrade though I'd prefer to run the current one into the ground first.

I have to charge once a month or once 15 days I didn't keep track tbh. And I read like crazy. I finished 22 books on the kindle this year so far.

Its a Lithium battery so unless you let it drain to single digits every time, it'll last a LOONG time
