Apple’s iPhone 11 Pro Max Battery: Lifespan, Performance & Replacement Guide
Apple’s iPhone 11 Pro and Max phones are among the best and most capable smartphones the company has ever made. They have powerful processors that will keep them relevant for years to come and absolutely stunning displays.
They also have large batteries that deliver exemplary battery life. However, their battery lifespan is limited by the chemical degradation of lithium ion.
How long does the iPhone 11 Pro Max battery last?
The iPhone 11 Pro Max has a 3,969 mAh battery, which is the largest in any Apple phone to date. This is also the fastest charging smartphone on the market and can replenish 50% of its battery in 30 minutes. The battery can be charged using a Qi wireless charger, Lightning connector or USB-C 3.1 Gen 2 port.
The bigger battery inside the Pro Max helps Apple claim a four-hour increase in its battery life over the iPhone XS and five hours over the iPhone XR. However, it’s difficult to determine how much of a role the increased battery capacity plays in those claims as the hard numbers Apple publishes are based on fixed tests that aren’t realistically how anyone uses their phones.
Both the iPhone 11 Pro and iPhone 11 Pro Max use lithium-ion batteries. These batteries are more efficient than older generation batteries and offer better power density for a larger capacity battery in a smaller package. However, all rechargeable batteries eventually degrade to the point where they need to be replaced.
The built-in software and hardware system in your iPhone monitors its power needs, and manages performance to reduce the effects of battery chemical aging. A normalized battery health indicator alerts you when your iPhone is approaching a battery replacement cycle. Apple recommends replacing your iPhone’s battery when it reaches 80% of its original capacity to maintain peak performance capability.
iPhone 11 Pro Max battery health check
If you want to know how long your iPhone 11 Pro Max battery lasts, you can check its health in Settings. The phone will display a graph showing activity and usage over the past 24 hours or up to the last 10 days. You can also see a breakdown of activity by app and a charge cycle history. The battery health graph will show how the battery has degraded over time, and will indicate when you should consider getting a replacement.
The new A13 Bionic chip in the iPhone 11 Pro runs fast, benchmarking well ahead of Android rivals and leaving plenty of headroom for gaming and other performance-intensive apps. Apple’s 6.5in Super Retina XDR OLED screen is stunning and the camera system is very capable, although it isn’t a big leap over what you get in cheaper phones like the OnePlus 7 Pro and check my site https://dienthoainhanh.com/thay-pin-iphone-11-pro-max/.
One downside of the phone is that it uses a Lightning cable rather than USB-C, and comes with only 64GB of storage. It also takes a while to charge up – the exhausted phone reached 80% in two hours and 20 minutes when we tested it. The phone can be charged wirelessly, though, and we managed to get it back up to 50% in 37 minutes. All iOS devices include fundamental performance management to ensure that the battery and internal components operate as designed, and are protected against damage from external environments and conditions.
Extend iPhone 11 Pro Max battery life
The battery is the heart of your iPhone and you should always do everything you can to extend it. Fortunately, there are a few tips you can follow to get the most out of your battery. First, make sure to keep your device updated. Every iOS update brings performance improvements and bug fixes that can help your battery last longer.
Another tip is to turn on Optimized Battery Charging. This feature will slow down the battery aging process by changing how your iPhone charges overnight. It will charge to 80%, then stop charging and let the remaining 20% drain until you wake up. This will allow your battery to spend less time at full charge, which in turn prolongs the lifespan of the battery.
Lastly, you should lower your Auto-Lock timeout to save battery life. This is a setting that turns off your iPhone screen after a certain amount of inactivity, and it can range from 30 seconds to five minutes. To do this, go to Settings Display & Brightness Auto Lock and select a shorter duration.
Finally, you can also use dark mode on your iPhone to extend battery life. This feature is especially helpful for iPhones with OLED screens, which consume more power to display brighter colors. By turning on dark mode, you can reduce your phone’s power consumption by dimming the display and activating features like Auto-Brightness.
iPhone 11 Pro Max battery replacement
The iPhone 11 Pro and 11 Pro Max get a substantial bump in battery capacity over their predecessors. The 11 Pro sees a 14.5% increase to 3046mAh while the Pro Max has a hefty 25% bump to 3969mAh. This bump in capacity is what allows the phones to become so much thicker this year and also adds 18g of weight.
The hefty new batteries help the phone last all day between charges, even with a massive 6.5-inch display and some serious gaming or entertainment use. Apple is also including an 18W USB-C fast charger in the box for a bit of speedy charging, and the iCloud service will finally slow down charging above 80% to preserve the life of your iPhone’s battery.
But just like any rechargeable, lithium ion battery, it will eventually wear out and need replacement. Apple doesn’t offer a way to track the number of charge cycles your iPhone’s battery has been through, but a third-party Mac app called coconutBattery 3 can give you some insight.
To open your iPhone 11 Pro Max and replace the battery, first use a suction cup to lift up the back cover. Once you can see the inside of your phone, place a flat stable tool (we recommend a plastic plectrum or iFlex) into the gap between the screen and the case to enlarge it.
