I got my iPhone’s battery replaced, and I’m angry Apple didn’t tell me to sooner:

Two weeks ago, I went to an Apple Store and had a new battery put in my iPhone 6S. The very next day, I realized how unusable my old battery had been making my phone.

The repair restored functionality that had been seeping away so slowly I hadn’t really registered the loss. Apps now load when I tap them, not when they feel like it. The keyboard doesn’t freeze when I try to reply to emails in Outlook. My phone no longer clings to its charging cable like it’s a hospital drip, and the battery itself has stopped taking surprise nosedives from 40 percent charge down to zero when I have the temerity to go outside in the cold. (Yes, cold weather kills batteries.) The trust is back in my relationship with my phone, but as a result, I trust Apple a lot less.

I’m angry too.

As an admitted fan of Apple I won’t lie, this is bullshit. I’ve always known, always, that performance degraded on my previous iPhones when I upgraded to the latest version of iOS. I didn’t need an official statement from Apple or any other company to confirm or deny my suspicions.

And now here we are getting new, discounted batteries from Apple.

Formula E is an interesting beast.

So what does it sound like when vehicles have no exhaust:

There’s even a live DJ during each race — or “EJ,” as he’s called — who pumps music into speakers around the venue to help make up for the lack of engine noise.

And:

While the racing has been great, the most common complaint about Formula E was lodged well before the series even debuted: its sound, or the perceived lack of it. Traditional race fans love (or love to hate) the sound of combustion engines, and a series that lacks the rumbles and roars usually found in other motorsports is fighting an uphill battle.

“There’s always going to be standard combustion [engine] series out there, and we’re not trying to get rid of them,” Bird says. “There’s no reason why a fan can’t appreciate and love the so-called ‘normal’ concept of racing but at the same time appreciate and love what we’re doing here with our machines.”

But let’s be clear: these cars aren’t silent. The electric motors produce a sound that is somewhere between that of a giant RC car and something out of The Jetsons. They might be whisper-quiet from few hundred yards away, but they register about 80 decibels when they zip by. That’s plenty of noise to get your heart pounding.

I get sad thinking about combustion engines going away, but like most things, we adapt quickly to the new and forget about the old: cigarettes in bars, new operating systems, pagers.
