Using MagSafe Charger with iPhone

Is it safe for the iPhone 14 Pro to remain constantly charging while connected to a MagSafe Charger and placed on a desk stand? Are there any potential drawbacks to occasionally taking the phone off the charger and putting it back on, even if the battery is fully charged? Should I only plug in the Charger when the battery level is low? I'm using the original MagSafe Charger in conjunction with an Apple 20W adapter. Seeking advice and insights from the community.

To ensure optimal performance and battery life for your iPhone, follow these recommendations:


  1. Always use a genuine charging cable to maintain the integrity and safety of your device.
  2. Avoid completely draining the battery to zero. Instead, it's advisable to keep your iPhone at least half-charged if you plan on not using it for an extended period.
  3. When it comes to charging, you have flexibility. You can choose when to charge, how long to charge, and how often to charge based on your needs and usage patterns.
  4. Regarding the power adapter, Apple offers a range of options, starting from the 5W adapter up to the 140W USB-C Power Adapter. The choice of adapter depends on your charging preferences, device compatibility, and desired charging speed.


Remember to prioritize using genuine accessories, maintain a reasonable charge level when storing your iPhone, and adapt your charging habits according to your own preferences and requirements.



iPhones are designed with a built-in mechanism to prevent overcharging. When your iPhone reaches 100% battery charge, it stops drawing power from the charger. This is achieved through a feature called "charge management."


  1. The iPhone's charging circuit constantly monitors the battery's charge level.
  2. When you connect your iPhone to a charger, it goes through different charging phases. It starts with a higher charging rate to quickly charge the battery, and as it approaches 80%, the charging rate slows down. and Optimise Battery charging takes over, if enabled on your device.
  3. Once your iPhone reaches approximately 95-100% charge, the charging current is significantly reduced.
  4. The iPhone intermittently charges the battery to maintain it at 100%, but it doesn't continuously draw power from the charger. This is also referred to as "Trickle Charging"
  5. When the iPhone detects that the battery is fully charged, it stops charging completely. It prevents any overcharging by not drawing additional power from the charger. The iPhone will rely on the battery's capacity to power itself until the battery level drops below a certain threshold, at which point it will resume charging to bring it back up.


This charging management system ensures that your iPhone's battery is protected from overcharging, which can potentially degrade battery health over time. It helps maintain the longevity and performance of the battery by optimizing the charging process.


It's worth noting that if you keep your iPhone connected to the charger for an extended period of time, such as overnight, the trickle charging may periodically top up the battery to keep it at 100% charge. This is normal behavior and is part of the charging optimization process.


Overall, you can rest assured that your iPhone is designed to handle the charging process intelligently, avoiding overcharging and protecting the battery's health.

Simple answer? No, you don't need to worry about any of that. The internet is full of misinformation about how to preserve battery life. Modern devices like your iPhone 14 Pro have advanced hardware and software designed for the express purpose of extending battery life as far as possible. Charging control is one of Apple's main priorities.
