A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics
    • 3.1) NEW RULE as of 5 Nov 2024, trying it out
    • 3.2) Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    • 3.3) Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct

I somehow feel wealthy when my phone and headphones are both at 100% charge together (self.showerthoughts)

You'll feel wealthier longer if you avoid charging your batteries to 100%:

Limiting the maximum charge gives a substantial increase to the overall life of a battery. If we measure the life of a battery not in cycles, but in the number of electrons it can deliver to your phone over its lifetime, then we’re looking at a possible increase of 400%. That is, your battery could deliver 4X the number of electrons. And yes, that means it could last up to four times as long, according to some simple testing

If a mobile device offer charge limiting, I always set it to 80%. Examples of those include my FairPhone4 running CalyxOS or my Flipper Zero running the Momentum firmware. If it's a cellphone and it doesn't have charge limiting, I'll use a Chargie. Any other device, I try to be careful if possible.

100% fair and I do generally follow that rule with my phone and mostly enable the "stop charging at 80%" feature but I've noticed two downsides to it:

  1. It occasionally needs a full charge / discharge cycle or it loses true 80%
  2. If I do it overnight I find the phone unusually warm in the morning which is quite disconcerting so I mostly manually manage it these days (OnePlus Nord 2T 5G). I'm hoping they fix that in the future.

I'm a bit more carefree with the headphones partly because it's harder to tell and partly because it's a much, much easier battery replacement.
