TL;DR

  • Android 15 is preparing to tweak the threshold that determines whether a charger is seen as fast, from a measly 7.5W to a more reasonable 20W.
  • The operating system has long considered any charging speeds of at least 7.5W to be fast, which is far, far below what actual fast chargers can deliver nowadays.
  • The change isn’t live yet in the latest Android 15 beta, though, so chargers that deliver 7.5W of power will still be seen as fast on Pixels.

Why not just show the charging W on the screen instead of 'fast'.

[–] You999@sh.itjust.works 51 points 4 months ago (1 children)

Because the less tech savvy people will be confused when the battery starts getting full and charging speed tapers off which will lead to complaints about their 20w charger only providing 3w of power.

Then give a setting to enable it in the developer settings.

[–] limerod@reddthat.com 31 points 4 months ago (3 children)

Android is catering to the general public. The average user would easily understand fast, slow and normal. 20w, 68w, 5w not so much. But, I agree not having to use apps or 3rd party cables just to see the charging watts would be great. Even a Dev flag to enable the feature would be cool.

[–] veroxii@aussie.zone 22 points 4 months ago (2 children)

That's ridiculous. People have been buying light bulbs based on Watts for around a century and understand that higher W means brighter and more power.

[–] jol@discuss.tchncs.de 23 points 4 months ago

Bad example. People are still confused with light bulbs. That's why they still say the equivalent wattage to incandescent bulbs.

You make it sound like a joke but that's literally all it takes here.

[–] dvoraqs@lemmy.world 6 points 4 months ago (1 children)

Fast, normal, and slow are not clear either, I think. We see here that the "fast" term needs to evolve because it probably feels pretty slow now. Wattages are pretty clear reference points when users come to understand what they mean, especially over time.

[–] rbesfe@lemmy.ca 4 points 4 months ago

Expecting the average user to understand numbers is a high expectation

[–] eyeon@lemmy.world 1 points 4 months ago

You could just show it as a percentage of max its trying to draw be default and show actual watts under a developer toggle

[–] hashferret@lemmy.world 16 points 4 months ago (1 children)

Seriously. This thought occurred to me the other day when I plugged my power bank into a car's charging port to check the wattage and wondered "why the fuck can't my phone just do this by default?" Do we actually not trust people to understand higher number = faster?

[–] SeekPie@lemm.ee 6 points 4 months ago (1 children)

I think they meant they plugged the battery bank into the car's phone charger?

[–] ryannathans@aussie.zone 2 points 4 months ago (2 children)

How does that tell them the wattage output of the power bank

[–] SeekPie@lemm.ee 8 points 4 months ago* (last edited 4 months ago)

Maybe they have a wattage reader on their charger/power bank/car?

[–] eyeon@lemmy.world 1 points 4 months ago

I assume they meant check the wattage of the car charger output. some powerbanks have displays now and can show you it's input or output.

.. All phones also have displays and should show you the same thing but don't.

[–] possiblylinux127@lemmy.zip 5 points 4 months ago

Many custom roms do that
