I just seen another version of this story:

For anyone who still has devices with old AA, AAA, C, D, or 9V type batteries in it I highly recommend you move over to the USB chargable Li-ion type of the same format.

Most of those devices dont work with traditional rechargable batteries like NiMH because the voltage is a bit lower. Even if they do work they tend to last only a short period of time because as they discharge the voltage drops even further. So your device will often die even with 70% of charge still in those batteries.

With the newer USB rechargeable Li-ion type batteries of the same form factor, however, you have a drop-in replacement that doesnt have those issues. They basically are a LI-ion battery with a built in charger but more importantly with a DC-Dc converter to keep the voltage fixed at the desired voltage (1.5V or 9V) for the entire life of the battery. So they work in any device that they can fit in and lasts a long time as they deliver 100% of their power before cutting out (at which point it drops from 1.5V directly to about 0V).

The only downside is if your device reports a battery percentage then it will report 100% battery right up until it hits 0.

Anyway I replaced all my devices with batteries like this and they last longer than regular batteries in some cases (especially with 9V)... so I am sold!

#postmarketOS 21.06, accelerated video playback with #Clapper and more!

#postmarketOS release v21.06 is out! This one is based on #AlpineLinux 3.14 which was just released half a month ago - we're getting pretty good at tracking alpine releases now 🥳

Read all about it here:

What's the current best in class software for the pinephone?

I don't need the cellular modem to work, but would prefer everything else be as close to functional as possible.

More progress on hardware-accelerated video playback on the @thepine64 #PinePhone:
https://github.com/Rafostar/clapper has been worked on to have accelerated video playback.
Read Brian Daniels great blog post on the topic:
