Apple Watch Series 4 lasts up to 18 hours on a single charge — just like its predecessors — and it somehow manages that with significantly smaller batteries.

An official Product Information sheet confirms Apple’s latest wearables have around 20 percent less battery capacity than Series 3 devices. It’s a testament to the power efficiency of the new components.

Apple promises that you’ll get better battery life if you upgrade to the iPhone XS or iPhone XS Max. Their cutting-edge A12 Bionic chips and power-efficient Super Retina displays should mean that they last longer than any other iPhone in between charges.

But is that really the case? One battery test has found that last year’s iPhone X actually has more stamina than its successor.

There are some things Apple never tells us about its iOS devices, so we have to wait until they go on sale and find out more for ourselves. But thanks to one regulator, we now know some important details about the new iPhone lineup.

Here are the battery sizes and RAM capacities of iPhone XS, iPhone XS Max, and iPhone XR.

The new iOS 12 Battery information section brings a massive improvement over the previous version. Whereas before you could see which apps used how much battery, and for how long, now you can see the charts that look like the Tim Cook section of an Apple Keynote. You can see your battery use in incredible detail, broken down by such categories as Screen On Usage and Screen Off Usage.

But that’s not all. You can see how fast the battery ran down, how the levels were at any time during the last 24 hours, and also a longer-term overview that shows your usage over time.

It’s so detailed that it can be a bit intimidating, so today we’ll take a look at how to read those charts, and how to get the best out of them.

Apple’s biggest keynote of the year is just days away and while the iPhone XS will be the main attraction of the event, Apple Watch Series 4 could steal the show with a bevy of new features.

Rumors about the Apple Watch Series 4 have been heating up leading up to next week’s event. Leaked images of the new wearable have already surfaced online, but there’s still a bit of mystery surrounding the new gadget.

Here’s everything we know about Apple Watch Series 4:

Many iPhone user experienced quick battery drain problems with iOS 11.4. This week, Apple introduced an operating system update designed to fix bugs with its predecessor. Did that take care of the complaints?

Comments posted online generally seem to show that iOS 11.4.1 squashed this battery bug. Not everyone agrees, though.

The first ever Lightning-charged power bank has finally arrived thanks to the folks at Belkin.

Say goodbye to that Micro-USB cable you’ve been carrying around.

Apple rolled out iOS 11.4 in late May, finally delivering AirPlay 2 and stereo support for HomePod. If you haven’t already updated, you might want to avoid it for now.

Some iPhone users are reporting battery life problems after installing Apple’s latest release. It seems the issue affects everything from the iPhone 6 to the iPhone X.

Apple ran short on a very vital part of the Mid 2012 and Early 2013 15-inch MacBook Pro with Retina display for over a year. But it now reportedly has plenty of batteries for these models in stock once again.

For months, Apple had been forced to waive the fee on battery replacements on these older models because customers were having to wait so long for the part to become available. 

Apple’s iPhone battery replacement initiative was supposed to be a way of Apple getting out of trouble, after news about its iPhone battery throttling was released last year.

But according to a new report, Apple is being a bit shady about its replacement policy by finding minor faults with iPhones that it charges users to correct before giving them their replacement batteries.
