Understanding Optimized Battery Charging
The Optimized Battery Charging feature is a smart addition to Apple’s battery optimization toolkit, including the battery optimization feature. It learns your daily charging routine using machine learning and delays charging past 80% until it predicts you’ll need a full charge. This means if you usually charge your phone overnight, the feature will hold off on charging past 80% until just before you wake up, reducing the time your battery spends at 100% and thereby slowing down the aging process.
When this feature is active, a notification on your lock screen will let you know when your phone is expected to be fully charged. The information about your charging habits is stored only on your device, ensuring your privacy while helping to extend your phone’s battery life.
Overheating Prevention
Overheating is a significant factor that can prevent your iPhone from charging past 80%. High temperatures can cause the iPhone to limit charging to protect the lithium-ion battery from damage. Running resource-intensive apps or charging in high ambient temperatures can generate excess heat, causing the phone to stop charging at 80%.
To avoid overheating, try the following:
Charge your iPhone in a cooler location
Remove any cases that might trap heat
If your iPhone gets too warm, unplug it and let it cool down before plugging it back in
These steps can help maintain optimal charging conditions for lithium ion batteries and extend your battery life.
Battery Health Management:
The objective of battery health management is to keep your battery levels optimized to extend its lifespan. Stopping charging at 80% helps prevent wearing out the battery too quickly, ensuring it stays healthy for longer. Battery optimization features aim to reduce chemical stress and preserve the battery’s health and longevity.
Disabling these features might lead to faster battery wear and a shortened lifespan. Thus, comprehending the trade-offs before adjusting your battery settings is vital.
How to Disable Optimized Battery Charging
If you find that the Optimized Battery Charging feature is more of a hindrance than a help, you can easily disable it. This might be useful if you need a full charge sooner than your iPhone predicts or if you frequently change your charging patterns.
To disable Optimized Battery Charging on iPhone 14 models and earlier, navigate to Settings > Battery > Battery Health & Charging and toggle the feature off. While disabling it can give you more immediate control over your charging, remember that this feature helps extend the overall lifespan of your battery.
Steps to Turn Off Optimized Battery Charging
Here are the step-by-step instructions to turn off Optimized Battery Charging. First, open the Settings app, then tap on Battery.
Next, go to Battery Health & Charging. Toggle off the switch next to Optimized Battery Charging. This will help preserve your battery’s long-term health.
Once this feature is turned off, your iPhone stops charging at 80% and will charge to 100% without pausing, giving you a full battery whenever you need it.
When You Should Leave It On
It’s generally a good idea to leave Optimized Battery Charging enabled if you charge your phone overnight or have a consistent charging routine. This feature is particularly useful for extending the overall lifespan of your iPhone’s battery and maintaining its health.
