Samsung has introduced Flex Titanium, a new display technology that will debut on its next-generation Galaxy foldable smartphones. Ahead of the upcoming Galaxy Unpacked event, the company has revealed how the redesigned display structure aims to make foldable devices slimmer, tougher and more immersive while making the crease less noticeable.

Flex Titanium combines titanium with a redesigned display structure

Flex Titanium is the result of Samsung’s seven generations of foldable display development. Instead of relying on conventional materials alone, the new design combines a titanium-alloy film with a titanium plate beneath the OLED panel. The titanium-alloy film replaces the polymer support layer and delivers around 20 times higher mechanical stiffness while remaining extremely thin at roughly one-third the thickness of a human hair. This helps Samsung achieve a slimmer display without compromising flexibility.

The titanium plate sits below the display module and has been redesigned with precision-processed holes that remove air gaps between the adhesive and the display assembly. This structure offers firmer support when the phone is fully opened while still allowing the panel to fold repeatedly. According to Samsung, the new construction also helps reduce crease visibility and improves the overall viewing experience.

Samsung has also upgraded the display with a new high-resolution architecture and next-generation organic materials. Along with delivering sharper visuals, these changes are designed to lower power consumption, making the display more energy efficient. The company says the combination of stronger structural support, improved flexibility and better display efficiency is intended to push foldable smartphones closer to the experience of a conventional flagship handset.

The new Flex Titanium technology will make its commercial debut on Samsung’s next Galaxy foldable devices, which are expected to be unveiled at the upcoming Galaxy Unpacked event. The company is likely to share additional details about the display and the new foldable lineup during the launch.

As we head into the second half of 2026, getting a smartwatch to last through a long weekend is no longer a challenge. The combination of high-density silicon-carbon batteries and more efficient processors means that multi-day battery life has simply become the baseline for most new devices.

For this list, we are focusing entirely on full-fledged smartwatches. While there are specialized, rugged watches built specifically for hikers and endurance runners that offer significantly longer battery life, they usually achieve that by stripping away everyday smart features and apps. If you are looking for a device that offers a complete wearable experience without needing a daily charge, here is a look at the most reliable options currently on the market.

Xiaomi Watch 5

This watch runs Wear OS 6, an operating system that typically drains batteries quickly due to its heavy app integration and background syncing. However, the Xiaomi Watch 5 manages to provide up to six days of battery life in standard smart mode, and up to 18 days if you switch to power-saving mode.

It achieves this by utilizing a 930mAh silicon-carbon battery, a newer battery technology that allows for higher energy density without increasing the physical size or weight of the watch.

Additionally, it uses a dual-chip setup, pairing a main Snapdragon processor with a low-power co-processor. The co-processor handles basic background tasks like step counting and notifications, which prevents the main chip from waking up unnecessarily and draining power.

This makes it a highly practical choice if you want access to the full suite of Google apps, such as Maps and Wallet, without having to charge your watch every night.

OnePlus Watch 4

Another strong Wear OS 6 option, the OnePlus Watch 4 offers about five days of battery life in its standard smart mode. If you use it heavily, meaning frequent GPS tracking for outdoor runs, continuous heart rate monitoring, and streaming music offline, that battery life drops to roughly three days.

However, if you need to stretch the battery further, the watch includes a dedicated power-save mode. By disabling the main processor and full Wear OS functions, it relies on a low-power co-processor to handle basic timekeeping, step tracking, and essential notifications, which can extend the battery life up to 16 days.

It is equipped with a 646mAh battery that supports fast charging, allowing you to fully recharge the device from zero to 100% in about 75 minutes.

The watch features a titanium alloy case and a bright LTPO OLED display. The LTPO technology is particularly helpful for battery conservation, as it allows the screen’s refresh rate to drop significantly when you are not actively interacting with it.

It functions well as an everyday watch that provides premium materials and can comfortably last through a long weekend trip without needing a charger.

Huawei Watch GT Runner 2

If you primarily want a smartwatch for tracking workouts and do not need access to third-party apps, the Huawei Watch GT Runner 2 (full review) is a very efficient option.

It runs proprietary HarmonyOS rather than a resource-heavy platform like Wear OS, it provides up to 14 days of battery life with light use, or about seven days under typical daily conditions.

For runners and hikers, the most relevant specification is its continuous GPS tracking capability. The watch can record up to 32 hours of continuous dual-band GPS tracking on a single charge, making it useful for marathons, ultramarathons, or multi-day hiking trips.

It also features a lightweight build at just 34.5 grams and a breathable strap, focusing entirely on comfort and detailed fitness metrics rather than smartwatch app ecosystems.

Apple Watch Ultra 3

For iPhone users wanting to stay within the Apple ecosystem, the Apple Watch Ultra 3 offers up to 42 hours of normal use on a single charge. If you need to extend that, turning on Low Power Mode will give you up to 72 hours by limiting background heart rate measurements and delaying some notifications.

While it does not last as long as the dedicated fitness watches, the S10 chip and watchOS 26 optimizations make it efficient enough to prevent the need for daily charging, even with an always-on display and cellular connectivity active.

When the battery does run low, the fast-charging capability is quite useful, a 15-minute charge provides about 12 hours of standard use, which makes it relatively easy to keep the watch topped up while you take a shower or get ready for the day.

Samsung Galaxy Watch Ultra

The current Samsung Galaxy Watch Ultra provides up to 100 hours of battery life in Power Saving mode, or 48 hours in Exercise Power Saving mode, drawing from its 590mAh battery. It runs Wear OS 6 layered with Samsung’s One UI 8 Watch interface, providing deep integration with Android smartphones.

For people already using Samsung devices, a practical detail is how the watch works alongside the Galaxy Ring. If you wear them both, they split the health-tracking workload. The ring can handle background tasks like monitoring your sleep and continuous heart rate, which lets the watch turn off those specific sensors to save battery.

This distribution of work can reduce the watch’s power consumption and extend its overall battery life by about 30%, depending on your daily usage patterns.

It is also worth noting that Samsung is expected to release the next-generation Galaxy Watch Ultra 2 later this month. According to recent hardware leaks, this upcoming model will be equipped with a larger battery capacity, which should further improve its overall longevity and reduce the frequency of required charging.

Samsung’s next Ultra flagship might not get the big design refresh that many people were hoping for. A new leak is pushing back against the widespread rumors of a completely new horizontal rear camera layout for the Galaxy S27 Ultra, suggesting Samsung is still considering smaller tweaks rather than committing to a radical change.

For the past few months, there’s been a lot of buzz about Samsung ditching its signature floating camera rings in favor of a Pixel-style horizontal camera bar. The speculation picked up steam after well-known leaker Ice Universe hinted at a redesigned rear camera module. But according to the latest report, those widely shared horizontal camera renders are “incorrect.”

While Samsung is apparently testing multiple design concepts internally, none of the current ones use that clean, minimalist horizontal layout. As you might have already expected, the company isn’t just thinking about how it looks. Instead of overhauling the camera housing just because the S27 Ultra has one fewer rear camera, Samsung is putting real emphasis on keeping manufacturing simple and costs under control. The final design will likely try to strike a good balance between looking premium and being practical to produce.

That approach fits right in with how Samsung has handled the Ultra series so far. They’ve mostly made small, incremental design tweaks over the last five years instead of dramatic overhauls. It’s helped the Galaxy S Ultra phones keep a strong, recognizable identity.

If Samsung goes with the more conservative route, the S27 Ultra could end up looking pretty similar to the S26 Ultra, with just some minor adjustments to the camera area to account for the reduced number of sensors.

Of course, it’s still really early. The Galaxy S27 Ultra isn’t expected until early 2027, so Samsung has plenty of time to refine or completely change the design. Like all pre-launch leaks, what we’re seeing now might not reflect the final product at all. For now, this latest info cools down some of the biggest expectations around the phone’s appearance.

Nearly a month after the beta 3 release, Samsung has just dropped another beta for the Galaxy S26 series, moving a step closer to the stable release. The latest release focuses on resolving bugs and issues that were found in the previous build.

The One UI 9.0 Beta 4 update for the Galaxy S26 series initially went live in India, and then quickly expanded to more regions, including the UK, Poland, Germany, and Korea. Only the US remains to receive the beta update, and the rollout could begin at any moment.

The latest beta update can be identified by a firmware version ending with ZZG4. It has a download size of about 1.25GB. While the update primarily focuses on bug fixes, it also includes the July 2026 security patch, making the device more secure than before.

Read the complete changelog below for a detailed look at the changes.

Galaxy S26 One UI 9.0 Beta 4 changelog:

• Improved an issue where the clock size appears abnormal when rotating the lock screen horizontally/vertically.
• Improved an issue where it does not operate normally when turning ON/OFF via Quick Panel or Settings while the Privacy Display routine is running.
• Improved an issue where the navigation bar disappears under certain conditions during games.
• Improved Ul performance issues that occur when opening and closing the Quick Panel.
• Fixed an issue where timer notification numbers are cut off or the Ul is unstable in Live notification.
• Improved an issue where the “Bluetooth audio media volume” routine action does not operate normally when connecting to vehicle Bluetooth via the Routines app.

If you have a Galaxy S26 running One UI 9.0 beta, you should be able to upgrade to the latest beta by navigating to Settings > Software updates > Download and install. Once the update package is downloaded, tap the Install now button.

Samsung would probably release a few more beta updates before the stable build starts rolling out sometime later this year. The stable One UI 9.0 is confirmed to debut later this month on the upcoming Galaxy Z Fold 8 and Galaxy Z Flip 8. A few weeks after that, older Galaxy devices will begin to receive the update.

The post One UI 9.0 Beta 4 rolling out to Galaxy S26 series: Here’s what’s new appeared first on Gizmochina.

Premium flagship phones aren’t immune to issues. Just months after launch, some owners of the Galaxy S26 Ultra are reporting a reddish tint appearing right in the center of the screen. While it doesn’t seem to affect every unit, the complaints are starting to pile up and have left potential buyers concerned.

Samsung has acknowledged the reports and says it’s currently running an internal investigation. According to users, the reddish patch usually shows up after two to three months of use, not right out of the box. This makes it different from the normal slight color variations you sometimes see on AMOLED screens. Samsung has previously said that overall red or yellow tints can often be fixed by tweaking settings, but this localized central discoloration feels more specific.

A lot of the speculation is pointing toward the S26 Ultra’s unique Privacy Display feature. This is a hardware-level technology that narrows the viewing angles to protect your screen from prying eyes. It’s great for privacy when checking banking apps or private messages. Some people are wondering if this feature, which intelligently controls light emission, might be causing uneven wear or discoloration over time. However, we can’t jump to conclusions yet. User photos alone aren’t enough to confirm something like burn-in.

So far, Samsung hasn’t confirmed any connection to the Privacy Display, the panel design, or specific production batches. In a statement, the company said: “We are currently examining the matter internally to determine the cause.”

At a premium price, buyers expect top-tier reliability. This reddish patch seen on the S26 Ultra, followed by the green or pink lines reported on multiple recent Galaxy flagship models, could shake user confidence fast. If the latest problem turns out to be widespread, we might see software fixes, panel swaps, or even a service program.

If you’re noticing something similar on your S26 Ultra, it’s a good idea to document it with photos or videos, try adjusting your display settings, and reach out to Samsung support.
