For the best performance, using a MagSafe or ESR magnetic charging case is strongly recommended.

Our Magnetic Cases are specifically designed for the iPhone 17 Series with a built-in powerful magnetic ring to ensure:

1. Secure Alignment: The charger snaps perfectly into the ideal position for seamless and fast charging, preventing slippage and heat buildup.
2. Full Protection: Provides military-grade drop protection while remaining fully compatible with all magnetic wireless accessories.

Using a standard case may result in weak attachment, interrupted charging, or slower speeds. Choose ESR iPhone Case for the optimal blend of safety, speed, and seamless magnetic power.

Yes. It’s completely safe to charge your iPhone 17 even if the battery isn’t low. iPhones use lithium-ion batteries, which don’t need to be fully drained before recharging. Topping up your battery won’t damage it. What affects battery health the most is heat—not the battery percentage.

To keep your iPhone battery healthy during charging, focus on minimizing heat:

• Use a certified charger, like an ESR iPhone 17 fast charger or an ESR 25W MagSafe charger.
• Avoid charging in hot environments.
• Remove thick cases if your phone feels warm.
• Always charge your iPhone in a well-ventilated, open space.

To speed up charging, consider optimizing the following:

1. Use a high-wattage charger (20W or higher):
   Apple recommends using a 20W or higher USB-C power adapter for optimal charging speed. For wireless fast charging, it's recommended to choose the ESR 25W MagSafe chargers or Qi2 chargers.
2. Enable Low Power Mode while charging:
   Turning on Low Power Mode reduces power consumption and helps your iPhone charge faster by limiting background processes.
3. Keep your iPhone cool:
   Heat can slow down charging. Charge your iPhone in a cool, well-ventilated area and avoid using a thick case while charging.
4. Avoid gaming or video playback during charging:
   Intensive activities like gaming or streaming videos can drain power and slow down the charging speed. It's best to avoid these while charging.
5. Use an Apple-certified USB-C or Lightning cable:
   High-quality, certified cables ensure efficient charging and minimize the risk of overheating.
