While the battery life on the iPhone 4 isn’t bad in comparison to most smartphones, we still find ourselves running low on a daily basis thanks to Web browsing, photo-taking, and that pesky Angry Birds game. Your iPhone can do just about anything: Let you communicate with friends, help you choose a restaurant, give you directions, or tell you if the price on that gadget is reasonable. When your phone dies in the middle of the day you realize just how often you use it to help with daily tasks. The Mophie Juice Pack Reserve ($35) aims to solve that problem with a keychain-sized battery boost that you can have on-hand at all times. 

The Juice Pack Reserve is small enough to attach to your keychain, which makes it extremely convenient, and will give your iPhone about a quarter of its full charge if you run out of juice. The gadget has an integrated 30-pin dock, USB port, and a special high-output battery cell that will charge up to twice as fast as traditional 500mAh batteries. Invisible LED lights let you track your iPhone’s charging progress at a glance. At this reasonable price and with such a compact design, we’ll be putting this on our key ring as soon as it’s released. No more bailing on your friends because your iPhone died and you’re incapable of finding directions sans-smartphone app. The Juice Pack Reserve also works with iPods, for those of you who still have them.

A person holding the Anker MagGo Power Bank.

Power banks are a necessary evil, and even if you don’t consider yourself a “power user” who's likely to drain a phone’s battery in less than a day, there will be times when one comes in handy. And when I am forced to carry one, I want it to be as helpful and versatile as possible.

I’ve been trying Anker’s MagGo Power Bank 10K -- meaning it has a 10,000mAh cell inside it -- and there are three reasons why I'm OK with it taking up valuable space in my bag.

Here’s how Apple could change your iPhone forever

Over the past few months, Apple has released a steady stream of research papers detailing its work with generative AI. So far, Apple has been tight-lipped about what exactly is cooking in its research labs, while rumors circulate that Apple is in talks with Google to license its Gemini AI for iPhones.

But there have been a couple of teasers of what we can expect. In February, an Apple research paper detailed an open-source model called MLLM-Guided Image Editing (MGIE) that is capable of media editing using natural language instructions from users. Now, another research paper on Ferret UI has sent the AI community into a frenzy.

There’s a big problem with the iPhone’s Photos app
The Apple iPhone 15 Plus's gallery app.

While my primary device these days continues to be my iPhone 15 Pro, I’ve dabbled with plenty of Android phones since I’ve been here at Digital Trends. One of my favorite brands of phone has been the Google Pixel because of its strong suite of photo-editing tools and good camera hardware.

Google first added the Magic Eraser capability with the Pixel 6 and Pixel 6 Pro, which is a tool I love using. Then, with the Pixel 8 series, Google added the Magic Editor, which uses generative AI to make edits that wouldn’t be possible otherwise. There are also tools like Photo Unblur, which is great for old photographs and enhancing images that were captured with low-quality sensors.
