When you get your hands on a foldable phone, you should be able to expect a large battery. After all, powering two screens takes some juice. The numbers, however, might not be what you’d expect. Today, an official energy label has confirmed that the newest entry in the foldable space, the iPhone Duo, touts only a 4883mAh battery.

As required by Europe, new smartphones have to publish their information for transparency. Apple is no different. In its label for the iPhone Duo, the company listed 4883mAh as the official capacity of its very first foldable phone. Previous rumors have likewise speculated that the device will have two battery cells totalling the above rating.

If we’re talking relative capacity, a sub-5000mAh battery feels too low for such a big device. But does that mean that users will run into battery issues? Right now, it’s too early to tell.

Despite the size, the device itself might be efficient when it comes to managing battery life. For reference, the Samsung Galaxy Z Fold8 Ultra has a 5000mAh battery but still offers impressive battery life for all-day use. And besides, the iPhone Duo’s folded screen is much smaller than other phones. Since users will likely stick with the smaller screen most of the time, the smaller battery should still last the whole day.

GrabCar Group Ride now splits the fare automatically among passengers, making it simpler to book such ride types.

Each rider can save up to 50% on fare as well when using a group ride, compared with booking a solo ride.

Regular ride buddies can also be saved as a group, together with frequent pickup and drop-off pins. This way, repeat bookings take just a few taps.

Such a system is ideal for officemates headed the same way or friends coming home from a night out, as well as plenty of other scenarios.

To book a Group Ride, follow these steps:

• Open the Grab app, tap GrabCar, then select Group Ride
• Enter your pickup point and drop-off
• Share the invite link with up to two friends
• Your friends can add their own drop-off points
• Confirm the booking to split the fare automatically

The GrabCar Group Ride feature is now available in all GrabCar cities nationwide.

Sony has unveiled three premium Walkman digital music players designed for audiophiles. The new lineup includes the flagship NW-WM1ZM3, NW-WM1AM3, and NW-ZX900, featuring upgraded audio components and technologies designed to deliver high-resolution sound.

The NW-WM1ZM3 and NW-WM1AM3 lead the lineup with premium copper components, upgraded power circuitry, and Sony’s S-Master HX digital amplifier technology. The NW-ZX900 also inherits select audio components from the flagship model.

Sony Walkman lineup emphasizes sound quality

The NW-WM1ZM3 features a gold-plated, oxygen-free copper chassis with 99.99% copper purity. Sony says its construction helps deliver powerful bass, a wider soundstage, and smoother high frequencies. It also uses KIMBER KABLE wiring to reduce noise and preserve audio signal quality.

The NW-WM1AM3 and NW-ZX900 combine aluminium-alloy main chassis designs with gold-plated copper rear chassis components. The WM1 models also feature upgraded power circuitry and larger copper coils to improve signal clarity and reduce distortion.

All three players support Sony’s S-Master HX digital amplifier technology, Native DSD audio, and balanced output. Their DSD Remastering Engine converts PCM audio into an 11.2MHz DSD stream. The updated implementation also works with music streamed over Wi-Fi, allowing listeners to use the feature without downloading their tracks.

Larger displays and longer battery life

The NW-WM1ZM3 and NW-WM1AM3 feature 5.5-inch displays, while the NW-ZX900 has a 5-inch screen. Sony says the larger displays improve navigation and make album artwork easier to view. Users can also customize the Walkman home screen.

Battery life reaches up to 35 hours of 128kbps MP3 playback on the WM1 models, with up to 31 hours of streaming playback. The NW-ZX900 offers up to 40 hours of MP3 playback or 35 hours when using streaming service apps.

Sony has also eliminated plastic from the packaging of all three models as part of its sustainability efforts.
