battery - Is charging iPhone all night harmful to my iPhone? - Ask Different
Lithium Polymer batteries, such as those used in the iPhone, are a very well understood battery chemistry and use specific chargers to manage their charging.

While the latest charging ICs Apple uses are proprietary (they work with Dialog for their power managment ICs) it is unlikely that Apple performs a significantly different charging process than every other battery charging IC manufacturer.

This process charges the battery as quickly as reasonable while protecting the battery from damage or increased wear and tear. Please note that the charging IC - or Power Management IC - is located inside the iPhone. So this applies regardless of the external USB powering device you use to charge it.

When the battery is full, the charger turns off the charging process. The battery is left alone without current going into or out of it. This is because most Lithium chemistry batteries don't like trickle charging (a process you may hear from others where a constant voltage and low current is applied to a battery all the time to keep it topped off).

Charging ICs therefore turn the current completely off and power the phone itself from the charger. This is the only time the battery isn't charging or discharging - when it's full and the phone is plugged in.

The battery isn't discharged and charged in some sort of cycle after charging is complete. I'm not sure where this myth stems from, because it would actually place additional wear and tear on the battery.

If You Type 1+2+3 Into Your iPhone's Calculator on iOS 11, You Probably Won't Get 6 - Slashdot
A reader shares a report: If you've upgraded your iPhone's operating system to iOS 11, try this: Go to the calculator app and quickly type 1+2+3. You likely won't get 6. You might get 23, or 24, or 16, or 32, or something else, depending on what buttons you tap and in what order, and, obviously, non...

Orthogonal pivots • Asymco
Horace Dediu:
<p>This [closure of Microsoft's Groove music service by the end of the year] brings to an end a long story of Microsoft in the music distribution business. It started nearly 15 years ago with technologies in Windows that allowed for purchase and playback of various media formats. Microsoft sought to enable a large number of music retailers to market music through its formats and DRM and transaction clearing.

Services such as AOL MusicNow, Yahoo! Music Unlimited, Spiralfrog, MTV URGE, MSN Music, Musicmatch Jukebox, Wal-Mart Music Downloads, Ruckus, PassAlong, Rhapsody, iMesh and BearShare and dozens of hardware players licensed Windows formats. Almost all of these services have shut down and the devices disappeared.

The next stage was to offer an integrated experience through the Microsoft Zune player and Zune Marketplace music service. This too failed and was replaced by the Xbox Music brand in 2012. On July 6, 2015, Microsoft announced the re-branding of Xbox Music as Groove to tie in with the release of Windows 10.

There was a time when Microsoft was thought of as the certain winner in media distribution. Inserting media into the Windows hegemony was classic “control point” strategy: owning the access points was a sure way to collect a tax on what transacted through the network.

Instead we are facing a market where media is consumed through new access points: phones, tablets and TV boxes. Netflix, Spotify, Roku, Google, Amazon and Apple are all offering distribution and some are investing in original programming.</p>

Why? Because - as I found when I wrote "<a href="https://www.amazon.co.uk/Digital-Wars-Google-Microsoft-Internet/dp/0749464135">Digital Wars</a>" - the modular approach to music players (someone makes the music player, someone else makes the DRM-enforcing software, someone else again offers the DRM-encoded music) produces an awful customer experience. If a problem arises, you're never quite sure whose fault it is, and nor are any of those in the chain; they all hand it off to someone else.

The iPod and the iTunes Music Store came straight through the middle of all that confusion:
<p>the long arc of history shows how hard it is to succeed in vertical integration after you build on horizontal foundations. Generations of managers graduated from the modular school of thought, specializing rather than generalizing. Now they are facing an integrated experiential world where progress depends on wrapping the mind around very broad systems problems.

Entire industries are facing this orthogonal pivot: media, computing and transportation come to mind. Huge blind spots exist as we see only what we’ve been trained to see.</p>
