Thanks to batterygate, the good news is that Apple will now switch out the battery in your old iPhone for $29 instead of $79, a price so cheap it would be crazy not to do it. But how do you take care of that new battery to stop it going bad? The truth is, the lithium ion batteries in phones and notebook computers have a finite life. But you can prolong that life with a few easy tricks.

Does your iPhone seem to get slower and slower as it grows older? Well, according to Apple, that is exactly what’s supposed to happen.

Many iPhone users have long suspected that Apple throttles performance of aging iPhones. The popular theory is that Apple does so to entice users to upgrade. However, Apple says there are really good performance reasons behind the practice.

Best iPhone 8 battery cases and backup batteries

Even the giant plus-sized iPhones run out of juice eventually, and that goes for the new iPhone 8 as much as any iPhone before it. You could carry a charger with you and spend the day hunting for available wall-sockets, but these days that’s as lame as using dodgy free Wi-Fi instead of reliable and fast LTE. Instead, you should take some backup power with you. There are two options: battery cases, great for really heavy phone users who always run out of power before lunch, and a spare battery with a USB cable that can charge your iPhone, or any device, but stays in the bottom of your bag until it’s needed.

Let’s take a look at the options. There’s also one very cool surprise feature in one of our picks that “wireless” charging fans are going to love.

Apple might team up with “expert technologists in batteries” from South Korea to create hollow lithium-ion power cells that will fuel the upcoming Apple Car, according to a new report.

While the name of the South Korean company hasn’t been revealed due to a nondisclosure agreement with Apple, it’s supposedly comprised of just 20 people. The South Korean team reportedly joined Apple’s secretive Project Titan automotive effort earlier this year, and the battery innovations could help the Apple Car stand out from the competition.

You don’t have to have had your iPhone die at an inopportune time to conclude that current generation batteries kind of suck.

Unlike most of us, however, Tesla CEO Elon Musk has the resources to do something about it.

In a press conference late on Thursday, Musk unveiled Tesla Energy: a line of new 7-10 kwh lithium-ion batteries aimed at homes, companies and utilities.
