Even a 7300 mAh battery can’t compete! The iPhone 17 Pro Max, with its 5088 mAh battery, firmly holds the throne as the king of battery life

Tech media outlet CNET recently conducted a large-scale battery life comparison test of 35 smartphones, and the results were astonishing: the iPhone 17 Pro Max, with its mere 5088mAh iPhone 17 Pro Max Smartphone Battery, beat the OnePlus 15, equipped with a 7300mAh OnePlus 15 Smartphone Battery, to claim the title of battery life king. This victory of “small battery, big battery” is redefining our understanding of smartphone battery life.

I. Real-world Ranking Domination: How Does 5088mAh Beat 7300mAh?

In a 3-hour video test, the iPhone 17 Pro Max ranked first with 91% battery remaining, followed closely by the OnePlus 15 with 90%. This means that after playing video continuously for 3 hours at maximum brightness, the iPhone 17 Pro Max only consumed 9% of its battery (approximately 458mAh), while the OnePlus 15 consumed 10% (approximately 730mAh). Overall Ranking: iPhone 17 Pro Max takes first place, iPhone 17 and OnePlus 15 tied for second, Poco F7 Ultra third, and iPhone 17 Pro fourth.

II. Technical Demystification: Why Small Batteries Outperform Large Batteries?

A19 Pro Chip: The Core of an Energy Efficiency Revolution

The iPhone 17 Pro Max is equipped with Apple’s latest 3nm A19 Pro chip, featuring a six-core architecture with two 4.26GHz performance cores and four efficiency cores. This chip achieves significant power reduction while improving performance.

CNET analysis points out that the  iPhone 17 Pro Max Smartphone Battery life advantage is mainly due to the deep collaboration between the A19 Pro chip and the iOS 26 system, achieving extremely high efficiency in power consumption control and resource scheduling. This is another victory for the “hardware-software integration” strategy.

Steel-Cast Battery and VC Heatsink: 3x Improved Heat Dissipation Efficiency

The iPhone 17 Pro Max also introduces steel-cased battery technology, improving heat dissipation efficiency by 3 times, maintaining over 80% capacity retention after 1000 charge-discharge cycles. The newly added VC heatsink system solves the frequency throttling problem under high load, allowing the A19 Pro chip to continuously release its performance, indirectly extending the iPhone 17 Pro Max’s battery life.

III. The Rise of Silicon-Carbon Batteries, But Optimization Remains Key

The Silicon-Carbon Battery Trend in the Android Camp

In this test, nearly half of the top five models in terms of battery life used silicon-carbon battery technology. Compared to traditional graphite anode batteries, silicon-carbon batteries can increase energy density without significantly increasing the thickness of the device, and are gradually becoming an important technological direction for the next generation of flagship phones.

The OnePlus 15’s 7300mAh battery and the Poco F7 Ultra’s 5600mAh battery both belong to the silicon-carbon battery camp. However, in CNET’s actual tests, these high-capacity silicon-carbon batteries still failed to beat the iPhone 17 Pro Max.

While the iPhone 17 Pro Max’s wired charging still maintains a 20W power, contrasting with the 100W-level fast charging of Android flagships, Apple achieved a turnaround in efficiency with its 50W MagSafe wireless fast charging: charging to 70% in 30 minutes.

IV. Conclusion: Lessons from the iPhone 17 Pro Max’s King of Battery Life

The iPhone 17 Pro Max’s 5088mAh battery beating the 7300mAh  iPhone 17 Pro Max Smartphone Battery is not only a victory for Apple, but also a reminder to the entire industry.

For consumers, when choosing a phone, it’s important to remember: battery capacity isn’t everything; energy efficiency is king. As CNET’s tests have shown, even a 7300mAh Android flagship loses to the 5088mAh iPhone.

iPhone 17 Pro Max Battery Life Overview:

iPhone 17 Pro Max Battery Capacity: 5088mAh (US version) / 4823mAh (China version); 3-hour video test: 91% battery remaining, 458mAh consumed; 45-minute intensive test: 99% battery remaining, only 1% drain; Chip: A19 Pro (2 4.26GHz performance cores + 4 efficiency cores); System: iOS 26 (Adaptive Power Mode + Smart Battery Management); Wireless Fast Charging: 50W MagSafe, charges to 70% in 30 minutes.

The iPhone 13 still had 32% battery remaining. Even in 2026, this battery performance remains impressive, far exceeding current mainstream Android flagship models.

Daily Use: One Charge a Day is Enough.

For the average user, the iPhone 13’s battery life can be described as “stable”: light users typically have 30%-40% battery remaining after a full charge in the morning; moderate users who only use it for watching videos, chatting, and scanning QR codes only need to charge it once a day. Actual testing shows that the screen-on time remains stable at around 6 hours and 20 minutes, fully meeting the needs of all-day use.

iPhone 13 Smartphone Battery Aging Issues

Even more impressive is the iPhone 13’s battery durability. Data shows that after three years of normal use, the battery health remains above 80%. Even if the health drops below 80%, Apple offers iPhone 13 battery replacement service.

IV. Upgrade Recommendations: Does Your iPhone 13 Need an Upgrade?

For users eager to upgrade:

If your iPhone 13 battery health is above 80%, you can confidently upgrade to iOS 26.3. Actual testing shows a significant improvement in battery life and smoothness after the upgrade. Many tech bloggers list it as their top choice, calling it a smooth “retirement-level” experience.

Apple Watch Ultra 2 battery life

Apple doesn’t reveal theApple Watch batterycapacity of its Apple Watches when it releases new hardware, preferring to discuss Apple Watch Ultra 2 batterylife in terms of days and hours of use. But information about the upcoming Apple Watch Series 9 and Apple Watch Ultra 2 has been hiding in Chinese regulatory databases, according to MacRumors.

The site reports that the capacity of the Apple Watch Series 9 has not changed, remaining at 282mAh and 308mAh for the 41mm and 45mm models, respectively. Despite this, the Apple Watch Ultra 2 batteryis still rated at 18 hours of battery life, presumably because the 25% efficiency savings promised by the new S9 chipset have been absorbed by the brighter screen, which can now reach 2,000 nits. The Apple Watch Ultra 2, meanwhile, is slightly larger — though the difference isn’t huge. The site claims that the Apple Watch Ultra 2 batteryhas a capacity of 564mAh — up from the 542mAh (or about 4%) of the Apple Watch Ultra 1 battery. Apple again says the Ultra 2 will still last 36 hours under normal use (the efficiency of the S9 chipset helps the screen reach a brighter 3,000 nits), but here’s where things get a little confusing.
The company also says the Watch Ultra 2 will last up to 72 hours in low-power mode, up from 60 hours on the original. That sounds like the S9 chip might be offering some clever tricks to save more power in power-saving mode, but maybe not. As MacRumors spotted, the fine print on each phone suggests the numbers were arrived at via different methods. The 60-hour figure was derived from 15 hours of hiking, “over 600” time checks, 35 minutes of app use, three minutes of calls, and 15 hours of sleep tracking. The 72-hour total came from 360 time checks, 180 minutes of app use, and a two-hour music workout over Bluetooth.

Logitech G502 HERO Mouse Battery Life Extension Maintenance Guide

Regarding Logitech G502 HERO mouse battery maintenance:

1. Charging Habits: The golden rule is “shallow discharge, shallow charge”: Avoid using the mouse until it shuts down completely before charging. Charge it when the Logitech G502 HERO mouse batter level is between 20% and 30%, and unplug it when it reaches approximately 80% to 90%. Lithium batteries are most “comfortable” in the 20%-80% charge range, significantly reducing stress during battery cycling and thus greatly extending their overall lifespan. Temperature Control to Avoid Overheating: When using and charging, keep the mouse away from direct sunlight, car interiors, radiators, and other heat sources. The ideal environment is a cool, shaded room temperature. High temperatures are the number one killer of lithium battery capacity degradation and accelerated aging. Keeping it cool helps stabilize the internal chemical reactions of the battery.

2. Software and Settings: Use G HUB to “save power”: Through the Logitech G HUB software, you can appropriately reduce the DPI refresh rate or turn off unnecessary lighting effects to reduce unnecessary power consumption. While this is primarily for extendingLogitech G502 HERO mouse batter life per charge, reducing frequent deep charge/discharge cycles indirectly helps extend the overall lifespan of the Logitech G502 HERO mouse battery.

3. Daily Use: Store at 40%-60% charge if not in use for extended periods: If the mouse will not be used for several weeks or even longer, charge the battery to 40%-60% and then turn off the mouse. Storing the battery at a full charge or completely depleted state for extended periods will cause irreversible damage. 40%-60% is the optimal dormant charge level for lithium batteries.

4. Physical Maintenance: Keep contacts clean: Occasionally check and clean the Logitech G502 HERO mouse battery contacts inside the mouse to ensure good contact. Good contact prevents charging abnormalities or misjudgments of Logitech G502 HERO mouse batter level due to resistance issues, allowing the battery management system to work more accurately.

5. Special Precautions: Do not mix or use inferior chargers: Although the Logitech G502 HERO mouse battery is rechargeable, ensure its quality is reliable. Inferior chargers may cause unstable voltage and damage the battery.

Immediately stop using the mouse if any abnormalities are observed: If you notice abnormal overheating, a bulging battery (causing deformation of the mouse casing), leakage, or an unusual odor, stop using the mouse immediately and contact customer service. Do not attempt to disassemble it yourself.

In general, extending the lifespan of your Logitech G502 HERO mouse battery is not complicated. The key is to remember to “keep it cool, charge and discharge it lightly, and store it at half charge when not in use for extended periods.” Developing good usage habits is far more cost-effective than waiting until the Logitech G502 HERO mouse battery is completely dead before replacing it.
