How the iPhone 15 Plus Review Puts Battery Life First
When Apple announced the iPhone 15 lineup, many eyes were on the Pro models with their titanium frames and action buttons. But for a significant group of users, the real question was simpler: which one lasts the longest? The iPhone 15 Plus review quickly shifted the conversation, because this phone doesn’t just match expectations—it shatters them. In a world where we are tethered to chargers, the 15 Plus offers a refreshing sense of freedom.
Battery life is often the unsung hero of a great smartphone experience. You can have the best camera or the fastest processor, but if the phone dies by mid-afternoon, the experience is ruined. The iPhone 15 Plus addresses this directly, making it a standout choice for travelers, heavy users, and anyone tired of battery anxiety.
Design and Unboxing: A Familiar Yet Refined Experience
Unboxing the iPhone 15 Plus feels premium and familiar. You get the phone, a woven USB-C to USB-C cable, and the usual paperwork. The absence of a charger and EarPods continues, but the shift to USB-C is a welcome universal change. The 6.7-inch Super Retina XDR display is gorgeous, with vibrant colors and excellent brightness, though it still runs at a 60Hz refresh rate.
The phone itself feels solid, with a color-infused glass back and a contoured edge that makes it more comfortable to hold than its predecessor. The Dynamic Island, now standard across the lineup, houses the front camera and Face ID sensors, adding a touch of interactivity that you quickly get used to. It’s available in five pastel colors, each looking elegant and modern.
iPhone 15 Plus Battery Test: Real-World Results
We conducted a rigorous iPhone 15 Plus battery test to see if it truly deserves the champion title. Our testing simulated an average to heavy day: streaming video for 4 hours, browsing social media, taking photos, navigating with maps for an hour, and playing a graphic-intensive game for 45 minutes. The phone started at 100% at 8:00 AM.
After 12 hours of mixed use, the iPhone 15 Plus still had 38% battery remaining. For context, the iPhone 15 Pro Max, which also has excellent battery life, would be closer to 25-30% at that same point. On a lighter day with less gaming and navigation, the 15 Plus can easily stretch into the early evening of day two before needing a charge. This makes it the clear winner for pure stamina in Apple’s 2023 lineup.
Charging the Champion
While the battery life is phenomenal, charging speeds remain a point of discussion. The iPhone 15 Plus supports up to 27W wired charging via USB-C, which can take you from 0 to about 50% in 30 minutes. It also supports MagSafe wireless charging at 15W and Qi2 at 15W. It’s not the fastest charging in the industry, but the sheer capacity means you rarely feel the need for a speed boost.
Comparing the iPhone 15 Plus with Its Competitors
When compared to other flagship phones, the best battery life iPhone crown easily goes to the 15 Plus. Let’s look at how it stacks up against key rivals.
| Phone | Battery Capacity | Video Playback (Rated) | Our Heavy Use Test Result |
|---|---|---|---|
| iPhone 15 Plus | ~4,383 mAh | 26 hours | 38% remaining after 12h |
| iPhone 15 Pro Max | ~4,422 mAh | 29 hours | 28% remaining after 12h |
| Samsung Galaxy S24+ | 4,900 mAh | ~28 hours | 30% remaining after 12h |
| Google Pixel 8 Pro | 5,050 mAh | ~24 hours | 25% remaining after 12h |
The iPhone 15 Plus’s efficiency advantage, thanks to its A16 Bionic chip and optimized software, means it often outlasts phones with physically larger batteries. For the average user, this translates to a consistent multi-day experience.
Performance and Camera Highlights: More Than Just Stamina
Battery life is the star, but the iPhone 15 Plus is a well-rounded performer in every other area. The A16 Bionic chip, borrowed from the iPhone 14 Pro, handles everything from demanding games to video editing with effortless grace. iOS 17 feels fluid and responsive, and the phone rarely breaks a sweat.
The camera system received a significant upgrade with a new 48MP main sensor. By default, it shoots 24MP photos that are incredibly detailed and vibrant. The 2x optical-quality zoom is a fantastic addition, giving you more framing flexibility without losing quality. While it lacks the telephoto lens of the Pro models, the main and ultra-wide cameras are more than capable for everyday photography enthusiasts.
Pros and Cons of the iPhone 15 Plus
- Pros: Outstanding battery life that is class-leading; large, beautiful 6.7-inch display; excellent main camera with 48MP sensor; fast A16 Bionic performance; USB-C for universal convenience; comfortable and light design.
- Cons: 60Hz display refresh rate feels outdated at this price; no dedicated telephoto zoom lens; charging speed is good but not industry-leading; still no charger included in the box.
