People who don't charge their phone at night... Why? (sh.itjust.works)

My wife's phone dies every. single. day. and I don't know why she doesn't just charge it at night.

I'm just wondering how people live like this 😅

If you're still convinced you need to run your battery down to zero you're operating on outdated knowledge of NiCad batteries and ruining your lithium ion batteries.

My Android phone has a built in functionality to charge so that it hits 100% when your alarm is rigged to go off. Idk about iphone though.

I was not talking about running the battery down to 0, that's no good for li-ion batteries either. I was talking about the exact, opposite, reaching 100% and staying there for hours on end (which happens during the night). With AccA I can set an upper limit.

Hi Tmpod! This is actually a common misconception among the general device-using public!

You are absolutely correct that a lithium battery will degrade if you maintain a state of charge (“SOC”) for long periods of time that is either above 90% or below 10%. Of course, phone manufacturers know this too, and they have set the charging software to block off the top of the pack, which allows the user to safely leave their phone on the charger indefinitely.

Why can't it be as easy as a relay (or transistor) switch that cuts off the power?

[–] Nugget_in_biscuit@lemmy.ml 2 points 1 year ago

This is basically how charging works today. There are transistors in the power management module that stop the battery from charging once it reaches the specific voltage that the software deems is appropriate
