  • Its not the best test imo. He only did 500 charge cycles which is more like 1.5 years worth of charge cycles. But even having data for 2 years isnt very useful. If you replace your phone after 2 years then there is no need to care about battery life at all. This whole thing of preserving battery life is something for people that want to use a phone for 5+ years without needing a new battery.

    In the first place, people have already done professional studies to analyze all kinds of lithium battery capacity degradation over many cycles and thats where the 30-80% number comes from. The whole introduction to his video is “there is a saying”, so all he had to do was actually look at the research where that “saying” came from. Then he could have still run his little experiment in an attempt to replicate parts of the study. Instead he basically told the viewers “if you throw away your phone after 2 years, then you dont need to care about charging limits” which is very useless information.

    After 1500 cycles the difference between the 5-100% and 30-80% system would be so drastic that you wouldnt be able to really use the first one, while the other one would still work decently well.


  • Gnome is so bad it hurts. I was reading a blog post by factorios linux dev earlier.

    Once Wayland support was implemented, I received a bug report that the window was missing a titlebar and close buttons (called “window decorations”) when running on GNOME. Most desktop environments will allow windows to supply their own decorations if they wish but will provide a default implementation on the server side as an alternative. GNOME, in their infinite wisdom, have decided that all clients must provide their own decorations, and if a client does not, they will simply be missing. I disagree with this decision; Factorio does not need to provide decorations on any other platform, nay, on any other desktop environment, but GNOME can (ab)use its popularity to force programs to conform to its idiosyncrasies or be left behind









  • They have a page about that: https://watchy.sqfmi.com/docs/battery-life

    With only time keeping, Watchy should have a battery life of 5-7 days, while with fetching data over WiFi, it should last between 2-3 days. These numbers can be extended through further optimizations (e.g. sleep during off hours, waking up only on motion/tilt, etc.).

    By default it wakes up the CPU and updates the display every 60 seconds, but you could totally change this to make it only update on demand (the most efficient would be by button press) which should extend the battery life waaay beyond 7 days.
