Best Note-Taking App for iPhone 15 Plus: Large Screen, All-Day Battery, Nemos

---

The iPhone 15 Plus was Apple's 2023 answer to an overlooked audience: people who wanted the big-screen iPhone experience without the Pro price tag. At launch, it offered the same 6.7-inch OLED display as the Pro Max, with a meaningfully improved battery over the standard model.

In 2026, many users are still running iPhone 15 Plus handsets — and for note-taking workflows, it remains a capable, well-supported device. This guide covers how to get the most out of Nemos on iPhone 15 Plus specifically.

iPhone 15 Plus for Note-Taking: The Advantages

Large Display

The 6.7-inch Super Retina XDR display gives you more text per page, more comfortable reading of longer notes, and a better landscape typing experience than smaller iPhones.

For note capture, screen size has a real impact: more content is visible when reviewing a note, scrolling through search results is more comfortable, and the keyboard in landscape mode is notably more usable.

Battery Life

The iPhone 15 Plus consistently delivered best-in-class battery life for non-Pro models. For note-takers who capture throughout the day — between meetings, on commutes, during field work — not reaching for a charger is a real advantage.

Dynamic Island

The iPhone 15 Plus introduced Dynamic Island to the non-Pro lineup. This isn't directly relevant to note-taking, but it removed the notch — giving you a cleaner full-screen experience when reading notes.

USB-C

The 15 Plus moved to USB-C, ending Lightning dependency. This doesn't affect note-taking workflows directly, but it means simpler charging and accessory compatibility.

Setting Up Nemos on iPhone 15 Plus

Lock Screen Widget

The 15 Plus supports lock screen widgets. Add Nemos to your lock screen for fastest-possible capture:

1. Long-press the lock screen → Customize
2. Tap the widget area below the clock → Add Widget → Nemos
3. Select the quick-capture widget

Now: glance at phone, tap widget, write note — without unlocking.

Home Screen Widget

For home screen capture and recent notes glance:

1. Long-press home screen → Edit → Add Widget (+)
2. Find Nemos → choose size → place widget

The 15 Plus screen accommodates a 2×2 or 4×2 Nemos widget comfortably. The large format shows recent note previews at a glance.

Action Button (Not Available)

The Action Button was introduced on Pro models in the iPhone 15 cycle — the standard and Plus models don't have it. If one-button capture is important, consider iPhone 16 Plus, which does include the Action Button.

For the 15 Plus, lock screen widget is the fastest capture path.

Note-Taking Tips for iPhone 15 Plus

One-handed use consideration: The 15 Plus is a large phone. If you primarily use one hand, position your Nemos widget in the bottom portion of the home screen for thumb reach. Enable Reachability (Settings → Accessibility → Reachability) for gesture-based screen pull-down.

Landscape writing: The 15 Plus keyboard in landscape is notably wider than smaller iPhones. If you write longer notes, try landscape mode for a better typing experience.

Split View with iPad: If you use an iPad alongside your 15 Plus, Nemos syncs via iCloud — notes captured on iPhone appear instantly on iPad for reference or longer editing sessions.

iPhone 15 Plus vs. iPhone 15 Pro for Note-Taking

The Pro added the Action Button and a more premium camera system. For note-taking specifically:

• Action Button (Pro only): One-button note capture shortcut. Meaningful if you capture very frequently throughout the day.
• ProMotion 120Hz (Pro only): Slightly smoother scrolling. Not relevant to writing quality.
• Camera system: Doesn't affect note-taking at all.
• Price: The Plus was $100–200 cheaper at launch.

For pure note-taking use, the 15 Plus and 15 Pro are equivalent in capability. The Action Button is the only Pro feature with direct note-taking relevance.

Is iPhone 15 Plus Still Worth Using in 2026?

Apple continues supporting the iPhone 15 lineup with iOS 19. Performance for note-taking workflows — text capture, search, iCloud sync — is not affected by being one or two generations behind.

Upgrade considerations for note-takers on 15 Plus: - Action Button: Only available on iPhone 15 Pro, 16 standard and Plus, 16 Pro. - Apple Intelligence: Available on iPhone 15 Pro and all iPhone 16 models. If AI Writing Tools are important to you, this is the main reason to upgrade. - Everything else: The 15 Plus handles note-taking as well as any current iPhone.
