The image is from GSM Arena. The phone Infinix has only 45W charge capability yet it does slightly faster than two other phones with much faster charging rates(and same battery capacity).

I know some phones throttle charging speeds but that is usually post 80% threshold. Why the discrepancy then?

    I don’t understand that chart really, but charging speed is carefully controlled in the phone, based on monitoring the battery temperature among other things. They won’t charge from 0% to 80% at 100 watts even if they might hit 100W momentarily under the right conditions. Fast charging is hard on batteries anyway. Make sure you are ok with replacing the battery every so often, if you’re going to fast charge regularly.

      Yep, this is it.

      They are trading battery longevity for faster charging.

      Personally, I generally prefer battery longevity, since that is the main factor that causes me to buy a new phone.

      This is also the main reason I would like to buy a Fairphone for my next phone. I can get a new battery for $50 and replace it myself. And with 8-10 years of updates, I figure I can actually use it for 8 years with two battery replacements along the way.

        Gonna be interesting to see which models disappear from EU altogether and which models get the better repairability and software updates next summer:

        Ecodesign requirements will apply to mobile phones and tablets put on the EU market from 20 June 2025 onwards, including:

        1. resistance to accidental drops or scratches and protection from dust and water
        2. sufficiently durable batteries which can withstand at least 800 charge and discharge cycles while retaining at least 80% of their initial capacity
        3. rules on disassembly and repair, including obligations for producers to make critical spare parts available within 5-10 working days, and for 7 years after the end of sales of the product model on the EU market
        4. availability of operating system upgrades for longer periods (at least 5 years from the date of the end of placement on the market of the last unit of a product model)
        5. non-discriminatory access for professional repairers to any software or firmware needed for the replacement

          I hadn’t read the regs before. Interesting.

          And while I very much agree with the intent (and will be glad to see it being much easier to replace a battery), I wonder what manufacturers will do to mitigate the impacts.

          Like for the 7 years of parts thing, will they manufacture/sell a phone for just 3 months, to minimize that window?

          I really like the OS support for 5 years. Again though, will they do things like charge for that support, tie the update package to a specific device, etc? (Guess we’ll see).

          I’m not saying this isn’t a great improvement over the non-existent rules - it truly is! I’m just cynical, so I’m concerned to see how manufacturers will attempt to minimize the impact to them.
