It looks like Apple has seriously decided to level up the iPhone 18 Pro and Pro Max. The new smartphones will feature screens based on LTPO+ technology. The sizes will remain the same — 6.3 and 6.9 inches — but the panel itself promises to be more power-efficient and more responsive to lighting conditions, which means there’s hope for improved battery life.
The display in iPhone 18 Pro will be top-tier
What Is LTPO+ and How Does It Differ from LTPO in iPhone 17 Pro
LTPO is a type of OLED panel that can dynamically change its refresh rate on the fly. It’s precisely what enables the Always-On Display feature in iPhones: the screen drops its refresh rate to a minimum and barely uses any battery when you’re not looking at it. A report from The Elec states that Apple is transitioning to an enhanced version of this technology.
The iPhone 17 Pro also uses a great screen, but iPhone 18 Pro’s will be better
The difference lies in the engineering details. In standard LTPO, oxide materials are only used in switching transistors, while in LTPO+ they’re also applied to driving transistors. Stripping away the engineering jargon, the essence is simple: the panel more precisely controls the current for each pixel and adapts more finely to ambient conditions. In simple terms, each pixel receives exactly as much energy as it needs at any given moment — no more, no less.
How LTPO+ Will Affect Battery Life and Display Brightness on iPhone
The upgrade to LTPO+ will give the iPhone 18 Pro two undeniable advantages:
- more efficient battery consumption and, consequently, slightly better battery life
- more responsive screen performance in low light — less flickering and graininess in the dark
The second point is more interesting than it seems. Many OLED smartphone owners complain about PWM and noticeable “grain” in the image at low brightness — for example, at night in bed. PWM flickering at low brightness is one of the most common complaints on forums, and manufacturers have been looking for ways to minimize it for several years. If LTPO+ truly smooths out this effect, those who frequently use their phone in the dark will benefit the most.
As for battery life — things are less clear-cut here. The screen in modern iPhones consumes a significant portion of energy, but the real improvement depends on the usage scenario. Those who watch videos for hours will notice the savings more than those who mainly text in messaging apps. However, there are no specific battery life improvement figures in the report. This means we can’t promise “an extra hour of usage” or other precise numbers yet — we’ll only see the real difference in tests after the release.
What Will the iPhone 18 Pro Design Look Like
This is what the new island on iPhone will look like
And while power consumption and brightness improvements won’t be noticeable to everyone, another advantage of iPhone 18 Pro over iPhone 17 Pro will be immediately obvious. Yes, I’m talking about the smaller Dynamic Island, which was recently confirmed by new renders. This is truly a display change that will be impossible to miss. What does this mean for users?
From a practical standpoint, nothing. It’s just a slightly smaller cutout that will look much more aesthetically pleasing. But all the animations and usability will remain at the same level. Well, maybe Apple will add a few more icons to the status bar, but I have a hard time believing that.
What We Know About the iPhone Ultra Display
The Elec doesn’t specify whether iPhone Ultra — a separate top-tier model that’s been rumored — will also transition to LTPO+. It’s logical to assume that the flagship version would receive the same or a more advanced panel, but for now this is speculation without confirmation. If confirmation appears, we’ll revisit the topic separately.
There haven’t been any rumors about LTPO+ in iPhone Ultra yet
Interestingly, the Ultra may also get unique display technologies that won’t be available in the Pro lineup. Apple already follows this approach with Apple Watch Ultra, where the screen is brighter and more durable than on standard watches. It’s possible that iPhone Ultra will offer higher peak brightness or additional panel protection.
Is It Worth Upgrading from iPhone 17 Pro to iPhone 18 Pro
In short — no, upgrading from iPhone 17 Pro just for the screen makes little sense. LTPO+ is an evolutionary improvement: slightly better battery life, slightly cleaner image in the dark. This isn’t the kind of upgrade worth selling last year’s flagship for.
However, if you’re still using an iPhone 14 Pro or older, the situation is different. Over two or three generations, many changes have accumulated: a new chip, improved cameras, Action Button, USB-C port. LTPO+ will be yet another argument in favor of upgrading, even if not the main one. For this group of users, it makes sense to wait until fall and get the current model right away.
Everyone else can safely skip this leak. It’s a rumor about a technological detail, not an announcement of a new feature, and the details may still change before the official presentation. Apple frequently makes adjustments to specifications right up until the announcement — remember how the camera predictions for iPhone 16 Pro kept changing before its release.
