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.

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.

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

L_2023214EN.01000901.xml

(eur-lex.europa.eu)

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.

Where can you see charge cycles?

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

Settings -> About phone -> Battery information

Doesn't show charge cycles for me, sadly. Samsung A52

around 38C

I was shocked when my new realme, which uses the same tech, didn't even break 30°C while charging at 8+ Amps (should be around 80W). This was in a relatively warm room (25°C) and using the case that came with it, which surely doesn't improve thermals. It gets warmer when charging from other sources with only 2-3A, like USB-PD or QuickCharge.

Coupled with the fact that it's only accurate if you are constantly charging from below 15% to 100%, these are ranges that I rarely get my phone into.

AccuBattery needs a session to have 60% charged, so <20% to 80% works. Doesn't need to be every single one. I actually asked support about it and they said this was the lowest percentage they were comfortable with. I was requesting to make it adjustable.

Accuracy of the measurement isn't the entire point. I see the same issue, but since it helps track relative degradation over time it can still add value by giving more information when you suspect the capacity is getting worse.

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.

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.

That's impressive. I'm looking at my phone now, not charging, but the screen is on, and it's at 33C. LOL

AccuBattery needs a session to have 60% charged, so <20% to 80% works. Doesn’t need to be every single one.

It's rare for me to get that low, even while charging to 80%.

But yeah, every so often I'll let it drain, then do a 100% charge to see what's up. I don't like doing that, because even Accubattery says that takes up more of a charge cycle than charging conservatively.

I do like the trend chart, although, the battery health on that actually went UP 5% between March and May

pixel also has the bad exonys chip that drains thier battery pretty fast. im using a oneplus12r right now, and it has 2 days of batteries if intensive usage(no gaming).

i did that for a month, it was actually more annoying than its worth, it made charge more often than i like. i was using a OPR12

I don't see that menu option. I do see Settings -> Battery but it does not count cycles.

They also say this:

In the absence of relevant standards and until the publication of the references of the relevant harmonised standards in the Official Journal of the European Union, the transitional testing methods set out in Annex IVa, or other reliable, accurate and reproducible methods, which take into account the generally recognised state-of-the-art methods, shall be used.

So I remain hopeful.

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.

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).

(Not saying this was your case, but generally good to check) - a finicky/wobbly USB type c connector has been a symptom of a dirty charging port several times in the past. Awful lint/dirt would get packed down into it, preventing the charger from fully inserting.

I ended up carefully and gently picking it out, though there are some delicate small contacts in there!

Anyway, good luck trying GrapheneOS! It's been my daily driver for months and past the learning experience it's great!

I'm on pixel 6a. There is no battery info there
