Apple begins investigation into iPhone 4S battery life

According to a report from The Guardian, Apple engineers have started contacting vocal iPhone 4S owners that have been complaining about the rapidly draining iPhone 4S battery. During the initial iPhone 4S presentation earlier this month, Apple mentioned that standby time for the iPhone 4S battery was rated at about 200 hours or a bit over eight days. This is a large drop from the 300 hour standby time of the iPhone 4 and iPhone 3GS, likely due to the upgrades to the internal hardware within the iPhone 4S. One iPhone 4S user reported that standby mode was eating up approximately ten percent of the battery power each hour and eventually draining the battery by the end of the workday.

iPhone-4S-battery-lifeWhile Apple engineers haven’t specifically identified the problem yet, many iPhone 4S users have collectively pointed to location services as the main culprit for the drain on the battery. Specifically, the “Setting Time Zone” function within iOS 5 that corrects the Time Zone as a user travels to different areas of the world is constantly attempting to check the current Time Zone. iPhone 4S owners who identified this problem see the purple, location arrow icon beside the toggle setting within the menu. This means that the Time Zone has been checked within the last 24 hours. Users that have turned off the Time Zone feature, as well as many other location functions of the phone, have reported vastly improved battery life on the iPhone 4S as well as other iPhones that have upgraded to iOS 5.

The “Setting Time Zone” function can be located within Settings, moving into “Location Services”, scrolling down to “System Services” and sliding the toggle on “Setting Time Zone”. Apple engineers will likely adjust settings within the next iOS 5 update to modify how often location-based apps are automatically updated to allow for greater battery life for all iPhone 4S users.

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

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.
