  • Apple aims to reinvent the battery with high-performance cathode technology

    What about solar battery regeneration? A lot of people use their phones outside. Would it be possible to install solar cells behind the display?
    The math doesn't work. Full sunlight on an iPhone 15 screen would produce about 9W. High efficiency solar cells might convert 22% of that, giving you about 2W of electric power. A transparent display is impossible, so you're going to block a lot of sunlight with the light emitting pixels. LEDs can't be transparent, as the light would emit in all directions, not just towards the viewer. Even with transparent areas between opaque pixels, I doubt you could get a fill ratio of less than 80%, and the transparent layer and screen surface will reflect a few % each. So you might get 100mW of power in full sunlight. I imagine such a display might consume more than that in extra power to make the transparency possible.

    Just get a cheap solar PV panel with USB output from Aliexpress. Sit in the shade with device to better see the screen and avoid it over-heating, put the panel in the sun et voila. A panel about iPad size does the trick. I often do this with my MacBook Air & iPhone connected for battery worry-free use when 'semi-working' outside at hotels.

    You can be sure the most valuable company in the World that happens to use batteries in almost all its products is researching battery technologies. However, there are limitations and risks. At the limit, you could have a nuclear powered phone but if you drop it, accidentally, take out a city. Safety-conscious applications such as aircraft and e-bikes that may be recharged in the home have moved to a less energy-dense lithium battery technology LiFePO4. Fast-charging will always degrade a battery's longevity, regardless of technology. Battery chemistries and charging strategies are a "bag of hurt".

  • Apple confirms that there is no Apple Silicon 27-inch iMac in the works

    32" is the new 27". You'll pay for it but get the best all-in-one money can buy, at any price, and it should last 20+ years.

    Next on the culling list is the Mac Studio. When a 14" MacBook Pro can outshine a Mac Pro in reported benchmarks, then the entire M3 SoC family can be fitted to a Mac Mini. There is simply no need for the Studio.

    Yesterday's announcement feels more like the death knell for the Studio. It always was a short-term product to cover up the lack of a Mac Pro. Now that an M3 Max can be put in a MacBook, it can be put in the Mini. The Studio should always have been Mini-sized. Only the top end Studio configurations justified the extra size and heat sinking - the lower-end Studios never did. The M3 range of Mac Minis will be coming out in a few months. They will embarrass the current Studio models, which I would expect to be quietly dropped. 
    It was never a short term product 
    The Mac Studio is a design monstrosity. It should never have existed. The previous design generation at Apple would never have countenanced it.

    It really feels like foolish to buy a Mac Studio M2 Max/Ultra right now. An M2 Max system comes to $3800…and slower than the M3 14” MBP spec’ed above.
    my guess would be the M3 studio line shows up when they can actually get the chip supply. the "missed opportunity" likely caused by the chips not being available in quantity yet. and something had to come out first.
