Automatically Power Off

ownedbycats · 01-23-2026, 12:00 AM

Is there any way, kobopatch or something, to set this to value higher than 60min?

Yes. See "Custom Sleep/Power-off timeouts" for libnickel in kobopatch. If you want really high numbers, you can use the "Larger Sleep/Power-off timeouts" patch, instead. Setting delays of > 12 hours may cause your timer to be overriden by syncing and other events, so don't set a huge number.

It doesn't work. I've tried it. I'm the one who asked for it originally.

Ah dang

I asked for this also in the past in the official firmware, for me the options available right now don't have any sense... 12, 24, 36, 48 hours are much more logical.

The options in the firmware are too short a time.

Yah, agree. They're same as the sleep options

It is a shame that the patch doesn't work.

As the energy management in sleep mode is miles behind of Kindle's, these 24 and 48 hours options are indispensable

Not sure why you are saying Kobo power management is miles behind a Kindle's. At one time, I compared my Clara HD and Kindle PW 4 by charging both up to 100% and then closing the covers. I then opened the cover and took a look at the battery level at ~one week intervals. The Clara HD battery lasted 2 weeks longer than the PW4 before opening the cover gave an I need charging screen.

Admittedly, this is a bit silly test since most people do not have multiple ereaders they do not use on a regular basis and if you are using USB to transfer books, that is also going to recharge your battery during the process.

My Libra 2 (and with my previous Libra 1 was the same) has a standby average battery consumption of 2-3% per day (without touching the reader) so after 35-45 days without use, it fully discharges. My Paperwhite 11th literally can be MONTHS in that state.

I think my Clara 2E loses 1% overnight. I'll try to remember to check tonight.

The PW5 lasts longer then my Libra 2 ever has.
