Surely I know when I want my phone's battery replaced, because I'm the one using it?

[–] [email protected] 18 points 11 months ago (7 children)

Most people can't tell how much battery life has been lost to wear and tear just by using the battery.

[–] [email protected] 5 points 11 months ago

This is especially true for users of Lineage os. Its hard to know if the reduced battery is related to updates or not.

[–] [email protected] 4 points 11 months ago (2 children)

If you don't notice an issue, there is no reason to replace the battery.
But if Google now puts a fat "your battery needs to be replaced" notification, those users who didn't even notice an issue are driven to buy a new phone out of fear their phone will explode.

[–] [email protected] 4 points 11 months ago

Now that is a good point. The average consumer will see that and think "gollygee I better spend more money." They don't have the knowledge needed to protect themselves.

[–] [email protected] 1 points 11 months ago

Yes, this is definitely an anti-consumer feature! /s

if I can't tell that my battery life has been reduced, why do i care? i'm literally oblivious to it

[–] [email protected] 4 points 11 months ago

I see this more as a tool for people who notice reduced battery life and want to do something about it. Currently they essentially need to guess if the battery is the issue and get it replaced to find out.

If you notice your battery life shortening, the health check can either confirm that you will see improvement with a new battery, or it will tell you your battery is okay, and reduced life is due to software changes or increased usage.

[–] [email protected] 1 points 11 months ago

Honestly sometimes I get carried away on my device and eat through 20-30% of my battery. And then start thinking it needs replacement because it felt like it's just been a few mins... before popping open the battery stats and realise i've actually been on my phone for hours πŸ€¦β€β™‚οΈ

Seems then if the user can't tell...

[–] [email protected] 1 points 11 months ago

Worse if you buy it used.

The phone I bought used was fortunately a company phone where the prior user barely touched it. So it lasted two years before really going to crap. But I've seen stories of used phones working fine for a few months then the battery just goes to shit.

[–] [email protected] 4 points 11 months ago (1 children)

But can you tell how much longer the battery will keep working?

[–] [email protected] 1 points 11 months ago (1 children)

does it see future? all it knows is the current calculated capacity and cycle count. the battery might continue degrading linearly, or it might go down a cliff. nobody knows.

[–] [email protected] 1 points 11 months ago (1 children)

Ever look at a weather report? Predicting the future according to a model whose inputs are measurements of things we can't directly perceive is something we do all the time.

[–] [email protected] 1 points 11 months ago (1 children)

You can predict things when you

  • know how things are now
  • have seen how similar events unfold in the future

Now who is keeping current performance data for every single battery batch? For every single battery model ever produced?

[–] [email protected] 1 points 11 months ago (1 children)

You're seriously gonna argue that having a complete history of a battery's usage and data from phones of the same model doesn't tell you anything more than a user's gut feeling about how well the battery is performing?

[–] [email protected] 1 points 11 months ago

Oh it will show the actual capacity. But who knows when will it fail (i.e. start degrading a lot faster)?
