From @fuckwit_mcbumcrumble@lemmy.dbzer0.com on a post over at !android@lemdro.id

Yeah this is just manufacturers self rating themselves. This is just like VW cars rating themselves as getting 5-10mpg better than their competitors, when really they were just measuring from the balls.

The up side is if they fail to meet those ratings then are the consumers entitled to some sort of compensation?

Btw, I love how Piefed shows comments from cross-posts. Every client should do it, helps make the fediverse feel bigger and more diverse.

How is battery life measured under this new EU regulation?

One interesting detail is that the battery endurance rating in the new labels is tested using the same software used by many tech reviewers: SmartViser. This French automation company works with labs and manufacturers to simulate real-world usage. So now, the battery performance you see on the label is based on consistent, lab-tested data, not just marketing claims.

[–] acosmichippo@lemmy.world 15 points 1 day ago

the actual legislation is not that specific as far as i can tell:

https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=CELEX%3A32023R1669#anx_I

Article 5

Measurement methods

The information to be provided pursuant to Articles 3 and 4 shall be obtained by reliable, accurate and reproducible measurement and calculation methods, which take into account the recognised state-of-the-art measurement and calculation methods, as set out in Annex IV.

Article 6

Verification procedure for market surveillance purposes

Member States shall apply the verification procedure laid down in Annex IX when performing the market surveillance checks referred to in Article 8(3) of Regulation (EU) 2017/1369.

Awesome! Good to know its based off some kind of standardized testing. This is good for everyone!

[–] ColeSloth@discuss.tchncs.de 7 points 1 day ago

It kind of isn't. The EU is giving the cell companies guidelines on how they should test their batteries, and then report their numbers back to the EU. So "Apple" are testing their apple phones and then telling the EU their alleged numbers.

Is piefed an instance?

[–] blah3166@piefed.social 14 points 1 day ago

Piefed is both an instance (piefed.social) and back-end server software that allows anyone to run their own instance (list of various Piefed instances). It works on the same ActivityPub protocol as Lemmy and Kbin/Mbin so they all interoperate with each other.

One of the cool things I like about Piefed is it seems to join the comments of various instances in cross-posts. On Lemmy, you can see its crossposted, but you have to manually check them out to see any comments on others. One cool feature I like over Lemmy. There's a few others, but I'd encourage you to check it out. You don't have to commit if you don't like it.

That’s strange, considering they all use the same battery suppliers.

[–] MangoPenguin@lemmy.blahaj.zone 8 points 1 day ago

Could be a difference in how they've set up charging cut off points.

[–] masterspace@lemmy.ca 7 points 1 day ago

Anecdotally it seems to be the case for me. I switched from the A series to the Pixel and I'm pretty disappointed in how quickly my battery life has degraded.

[–] jalkasieni@sopuli.xyz 7 points 1 day ago

It makes sense once you consider that these numbers are the manufacturers self reporting. That means they aren’t comparable, so drawing conclusions like ”manufacturer X has better batteries than manufacturer Y” from these numbers is silly.

[–] gonzo-rand19@moist.catsweat.com 6 points 1 day ago

Well, it could be that their electrical design or engineering teams have a bigger budget for prototyping and R&D. It's not just the battery that affects the charging function.

[–] rc__buggy@sh.itjust.works 5 points 1 day ago

It's got to be a lie

[–] ColeSloth@discuss.tchncs.de 5 points 1 day ago

Doesn't mean they use the same chemistry. There's a lot of different lithium batteries.

Samsung isn't even using the latest\greatest tech in cell phone batteries. The Redmagic 10 pro uses a silicon-carbon anode based battery in a dual cell form. It means fast charging is split between 2 batteries so there's less battery damage on a recharge, and the chemistry is more energy dense.

Also, it seems the cell phone companies self assess the tests and report them to the EU, so take the whole thing with a grain of salt.

[–] Showroom7561@lemmy.ca 31 points 1 day ago (1 children)

1,000 charge cycles: OnePlus 13

Hmm. This one has newer silicone-carbon lithium-ion batteries, which should actually increase charge cycles, so what's happening here?

[–] MentalEdge@sopuli.xyz 23 points 1 day ago (2 children)

Isn't one plus one of the brands that has their own fast charging tech, that's extra fast?

Makes total sense if they traded in longevity for speed.

[–] Showroom7561@lemmy.ca 14 points 1 day ago* (last edited 1 day ago) (1 children)

Isn’t one plus one of the brands that has their own fast charging tech, that’s extra fast?

Yes, but...

OnePlus offloads heat to the charger, so the phone actually doesn't get hot while charging. This fact alone would IMPROVE charge cycles, even at fast speeds.

But OnePlus also uses quite a few "tricks" to preserve battery health. Did the test include those features or did they turn them off. And if they turned them off, did they do the same with the Samsung phones (which have similar battery-health preserving options)?

I've had my OP13 since the day it came out (around 5-6 months) and keep it charged to 80% (built-in feature) and only charge it to 100% when I'll be out for the day and need to use GPS with max screen brightness. Battery health is still 100%.

I've owned a lot of Samsung phones before that, and the battery health was the only reason I've needed to replace them. So, I'm glad to see that the EU is taking charge cycles into account.

One piece of the puzzle that the numbers don't mention, is that the smaller battery of the Samsung phones means you'll be charging more often (i.e. more charge cycles) vs. something like a OP13 with a larger battery and excellent battery life (i.e. fewer charge cycles for the same use). Maybe that balances things out, but I'm still shocked that Sammy can get 1000 more charge cycles, which is YEARS more battery health than the other brands.

edit: clarity

[–] MentalEdge@sopuli.xyz 7 points 1 day ago* (last edited 1 day ago) (3 children)

OnePlus offloads heat to the charger

Some of it. They omit some circuitry that would have generated additional heat in the phone, and have it in the charger instead, but that doesn't magically mean the battery itself wont generate the inevitable heat caused by being charged faster. The battery itself only accepts one voltage, so the only way to charge it faster is amps.

And my feeling is that they aren't using the gains from this to make the batteries last, as SUPERVOOC is faster than pretty much every other standard. That makes me think they turned in any and all gains in battery health, for speed.

Most chargers send the additional energy via the cable in the form of extra voltage, because that doesn't require a special cable. Turning that voltage into amps in the phone produces a little bit of extra heat, but that doesn't mean that by eliminating that step, you get none from the battery itself as it charges. You can technically charge with a higher voltage, if you set up a phone such that it has more than one lithium cell. Some phones do this, but this doesn't require the OnePlus approach of using a special charger that provides a higher current, since any fast charger that can do the usual higher voltage method of providing extra power will work.

Like you say. I'm curious how they test this. Even if one battery gets more cycles, it'll degrade with time, as well. iPhones fast charge, too, but not with the chargers that used to come with the phones. You have to get one specifically for fast charging to get faster-than-normal charging.

Also, a tip. You may want to use something like AccuBattery to actually measure the state of the battery. Batteries, being chemical devices, have different capacities straight off the production line simply by virtue of not being chemically identically down to every molecule. (My Xperia 1 V unfortunately came with 93% design capacity, still within manufacturing tolerance, but the lowest I've seen on a new battery, it can be a bit of a lottery)

The built-in battery health monitor will just say "all good" until it isn't. AccuBattery has allowed me to monitor every percentage of degradation over the lives of my last few phones.

Before anyone rushes to replace their phones my Pixel 5 is nearly 5 years old, still on original battery (would be on at least 1200 cycles) and is presently sitting at 92% and claiming 1 day 11hrs remaining. Off the charger since 9:45 this morning and used for streaming music to my car while I was driving earlier. It still easily holds over 24 hours charge in my usage, so if I forget to charge it at night it's usually around 40% in the morning and I can plug it in sometime in the morning to top up. Perfectly useable after almost 5 years, and this is pretty normal for Pixels in my experience.

Love the new EU measurement standards but per other people's comments above they do not seem to mandate strict third-party testing, but rather rely on manufacturers submitting their results and adhering to the set test standards. This has not worked out well in the past, it should be mandatory third-party.

Cannot wait to see the return of user-replaceable batteries (thank you again, EU).

Although, replacing the battery on the Fairphone is so much easier that 1000 cycles is acceptable.

Sorry, no way I am going back to Samsung. I had the A71 and it was a TERRIBLE smart phone. I switched to the Pixel 6 and it was night and day.

I just need to get off my ass and install Graphene.

[–] Natanael@infosec.pub 18 points 19 hours ago

The Pixel line is comparable to the Samsung S line, you got a budget phone before

[–] Mr_Dr_Oink@lemmy.world 15 points 11 hours ago* (last edited 11 hours ago)

From a budget phone to a flagship?

Yeah, i can see how the difference would be night and day....

Regardless pixel is a great series of phone if the OS works for you then stick with google phones.

Personally i like samsung. Even if they have gotten pretty shady. Since i owned the s2 years back i have always found myself liking samsung.

Tried nexus 6, tried the OG pixel which i liked but ruined when i dropped it in a barrel filled with potatos and water. (No k wont elaborate, its more fun to leave you guessing)

Tried huawei and enjoyed my p20 pro and p30 pro but once the fold 3 came out i was back with samsung. Got a fold 6 now and am very happy.

If i recall, since the advent of smart phones, i went: Sony xperia x10, Galaxy S2, Galaxy S4 mini, Google Nexus 6, Google Pixel, Huawei P20 pro, Huawei P30 pro, Galaxy Fold 3, Galaxy Fold 6,

I'm at 943 cycles on my Pixel 6 Pro and it's still going strong. I slow charge it every night and try to avoid fully draining the battery to slow down the deterioration, which seems to have worked pretty well. Thankfully a battery replacement is only $50 so it won't cost much when I do have to replace it.

[–] phx@lemmy.ca 7 points 1 day ago

Yeah I've got a P7 Pro and the battery is still fine. Adaptive charging enabled to help batter life.

Handed my P6 down to my daughter and it's still fine for her too

[–] lauha@lemmy.world 6 points 1 day ago (7 children)

Where can you see charge cycles?

[–] BassTurd@lemmy.world 4 points 1 day ago (1 children)

I had the same phone, and the only reason I replaced it was because the USB C port was finicky. It must have been damaged at some point and when plugged in, the cable had to be just right. Wireless charging works great, but I wanted the stability of being able to plug in and know it would discharge over night when I didn't have a wireless charger. Otherwise, I had no issues with the battery, and I got the phone when it was pretty new to the market. I swapped it out just a few months back, and it's going to be my test phone for grapheneOS and may end up being a communal remote.

That data is independently researched or Samsung gave that to the EU and it's published as-is?

[–] kilgore_trout@feddit.it 21 points 16 hours ago

The new law does not mandate third-party review. It's the innkeeper claiming that the wine is good.

I find that I wear out the charging port before the battery. I don't even plug it in that much either.

Wow. This is excellent for Samsung users.

I believe these are just claims rather than actual tests or measurements right?

Apparently not

I can anecdotally attest to this. I've been using the same Samsung phone since basically 2020 with original battery and the runtime is still damn good for what I need.
