Even though Samsung has made significant improvements in Galaxy’s software optimization, the battery life aspect remains one of the most criticized. As we start to discuss the Galaxy S27 Ultra, I want Samsung to add extra battery life to the flagship phone.

Samsung is behind in battery capacity in flagships, as compared to its Chinese rivals. Competitor brands like Xiaomi, Honor, and OnePlus shipped their devices with massive battery sizes, even though they are still irrelevant.

Galaxy S27 Ultra should improve battery life

Rumor has it that the Galaxy S27 Ultra might get big structural changes inside and out. The vertical camera setup would be replaced with a horizontal module. The aim is to vacate space inside and use better sensors and probably a bigger battery.

Samsung might not be jumping to silicon-carbon battery anytime soon. Meanwhile, an mAh bump in the current capacity isn’t impossible. If rumors are accurate, the Galaxy S27 Ultra may have more mAh than the S26 Ultra.

If Galaxy S27 Ultra gets a battery of 5200mAh or 5300mAh, this would make a big impact on the overall battery life. The current 5000mAh still survives moderate usage all day long, but it starts worrying users when they are out.

Battery bump alone can’t make it happen

As AI continues to increase resource consumption, system-level changes have become necessary. We see phones with 6000mAh and 7000mAh batteries dying before Galaxy and iPhone.

Samsung has to work on multiple fronts, including chip optimization, software, and battery capacity. An expansive AI feature set is going to be more power hungry, and the next-gen chip could also require more power.

Snapdragon 8 Elite Gen 6 or 6 Pro could power the Galaxy S27 Ultra. It will be manufactured using TSMC’s 2nm process node. This technological upgrade will also improve power efficiency apart from upscaling performance.

Preinstalled One UI version is considered the most stable and reliable firmware. Users start to face battery life issues after installing major updates. Samsung should address that problem at the earliest before the situation worsens.

Galaxy S26 Ultra introduces Samsung’s Ultra AI features that help it stand out in 2026. The company’s latest press release highlights the features that make the device an ideal companion for Summer travel in the US.

The headline feature is something no other phone has pulled off: a built-in Privacy Display. Camera-wise, the Galaxy S26 Ultra ships with Generative Edit, Super Steady video with Horizontal Lock, and Nightography video designed for low-light shooting.

Samsung highlights in its latest press release:

Galaxy S26 Ultra features the world’s first built-in Privacy Display, along with AI-powered camera enhancements like Generative Edit, Super Steady video with horizontal lock, and Nightography video for clear and vibrant footage.

It’s Samsung’s first device to support APV, a professional-grade video codec. Additionally, the chipset is customized, and the thermal management is upgraded for sustained AI workloads.

Plus, Galaxy S26 Ultra is Samsung’s first-ever device to support APV, a new professional-grade video codec. S26 Ultra also has a customized chipset and upgraded thermal management for more powerful AI experiences, wrapped up in the slimmest Ultra yet.

Galaxy S26 Ultra topped US Consumer Reports’ ranking:

Samsung Galaxy delivered in the premium smartphone category with the latest Ultra model, underscoring the tech leader’s competitive edge when Galaxy S26 Ultra emerged as Consumer Reports’ top-rated phone.

Samsung is offering up to $720 off with an eligible trade-in through the official website. Carrier and retailer deals are also running for the summer. If you’ve been sitting on an older Galaxy, this is the window.

From the Galaxy S26 series to older flagships and even unannounced foldable devices, Samsung’s Android 17-based One UI 9 software machine is running faster than anyone expected, and the firmware leaks prove it.

There’s a version of Samsung that spent years being mocked for slow software. The company that would trail Google’s Pixel updates by months. The Samsung, whose major OS upgrades felt like cautious, methodical exercises in risk-avoidance.

In the first week of June 2026, a picture has come into sharp focus: One UI 9 is not following the old playbook.

It is accelerating at every level simultaneously: Beta Program, internal testing timelines, and device breadth in a way that suggests Samsung has structurally changed how it builds software.

Galaxy S26 Public Beta

Samsung’s second One UI 9 Beta dropped for the S26 lineup just two weeks after the first. The first Beta was limited to four countries, while the second Beta spread market coverage as well.

Two Beta releases in a month, with real bug fixes and expanding geographic coverage, speaks to a development team operating with uncommon confidence.

Galaxy Z Fold 7 and Flip 7 Internal Beta

Meanwhile, leaker Fahad Ali Javed has surfaced firmware data pointing to One UI 9 development already underway across Samsung’s 2025 flagship lineup.

An internal stable One UI 9.0 build spotted on Samsung’s server with the June security patch level. A stable internal build for the Fold 7 and Flip 7 this early in the cycle is well ahead of historical precedent.

Galaxy S25 internal One UI 9 firmware

The very first Galaxy S25 firmware triplet for One UI 9 was discovered only via direct server fetching. The build string carries a stable (ADZ) prefix rather than the typical Beta (ZZxx) marker, strongly suggesting internal testing has skipped straight to a stable track.

• S931BXXUADZF3
• S938BXXUADZF3

Skipping that step for the Galaxy S25 series suggests an accelerated internal schedule. It also seems that Samsung has restructured the process of moving from internal testing to public Beta, potentially compressing the timeline significantly.

For context: Samsung’s upcoming foldables are expected to be the first devices to ship with One UI 9 out of the box, at the Unpacked event in London likely on July 22.

Samsung Electronics’ foundry business is expected to turn profitable as early as the third quarter of 2026. This would mark the end of four years of heavy losses and signal a strong recovery for the division.

According to Biz Chosun (via @SemiconductorsX), the company has made solid progress. Its 2-nanometer GAA process has already achieved over 60% yield in the first quarter, a key step toward the 70% level needed for efficient mass production.

In addition, major orders are also supporting results, including a large autonomous driving chip deal with Tesla and chip production for Nvidia. Thanks to the high demand for HBM base dies, supplies are already selling out quickly.

Another positive factor is Samsung’s massive Taylor fab in Texas. Once it ramps up production in the second half of the year, it should help cover fixed costs instead of adding to them.

This turnaround is significant because Samsung’s foundry business has been a weak spot compared to TSMC for years. With TSMC’s advanced lines busy serving AI chip demand, more customers, including Apple and Nintendo, are turning to Samsung as a reliable alternative.

If this good momentum continues, Samsung can become stronger in the competitive foundry market and significantly improve its overall semiconductor profits.

Samsung has reinvented the Alarm screen in One UI 9, and it makes the design literally better. The app is getting a major upgrade over the One UI 8.5, and it seems Samsung actually thought “we can do better here.”

One UI 9 Alarm screen brings three changes

Samsung has repositioned the Alarm label at the top. The label is now placed where it should have been years ago. It’s a minor change, but it makes a significant impact on the overall visual approach of the function.

You won’t be confused between Timer and Alarm.

The next major change was applied at the bottom. The button to dismiss the alarm has removed the dual border design in favor of a cleaner design button, which is a little better and simpler.

The double-button system to adjust snooze delay has also been tweaked. Rather than separate buttons accompanied by a prominent pill, the buttons have joined the pill to turn a single hub.

Samsung’s decision to bring the Alarm label to the top has increased space among the three central components, including the label itself, clock, and day plus date.

The One UI 9 Alarm screen has increased padding compared to One UI 8.5. This difference offers an even better appearance to the alarm screen, which you wake up to every morning.

Note that you can’t bring back the Alarm label to the bottom. All three available redesigns staple the label on the top, and it’s something Samsung has nailed with.

Samsung has made plenty of minor changes across the user interface in One UI 9. These changes collectively improve the overall visibility and aesthetics of the software. Do you like the new Alarm screen redesign? Let us know through X at @thesammyfans.
