Understanding Your Charger
At CompletedLines, we believe you should understand your tech as well as you love its design. Here’s a deeper look at common questions about wireless charging, using straight-from-the-source information from Anker's engineering team and Apple's iOS guidelines.
Q: Why does charging sometimes pause at 80%? Is my battery faulty?
A: This is not a fault; it's a sophisticated feature designed to protect your phone's long-term health. Your iPhone's operating system (iOS) continuously monitors battery temperature. If the phone or the power bank gets too warm during charging, iOS will automatically pause charging at around 80% to prevent lithium-ion battery degradation caused by heat. Charging will seamlessly resume once the temperature normalizes. Think of it as your phone's built-in guardian, ensuring your battery lasts for years, not just one charge cycle.
Follow-up Q: How can I prevent this from happening?
A: To minimize thermal throttling, avoid using graphics-intensive apps or games while charging. Also, try to charge your phone in a cooler, well-ventilated environment, not on a soft surface like a bed or under a pillow.
Q: Why does my phone display a "Slow Charger" alert? Isn't this a fast charger?
A: This can be confusing! The Anker Nano is indeed a Qi2-certified 15W fast charger. However, the "Slow Charger" alert is iOS's way of telling you it has intentionally reduced charging speed to manage heat. This is a safety protocol, not a reflection of the charger's maximum capability. The charging process is still perfectly safe and effective; it's just temporarily slower to keep your device within a safe temperature range.
Follow-up Q: Does this mean the charger is getting too hot?
A: Not necessarily. The charger itself is designed with advanced graphene cooling and stays within safe limits (below 104°F/40°C). The alert is typically triggered by the combined heat generated by the phone's battery and the charger. It's a system-wide precaution.
Q: Why is the effective battery capacity lower than the advertised 5,000mAh?
A: This is due to fundamental physics of energy transfer and conversion. No power bank delivers 100% of its rated capacity to your phone. Energy is lost as heat during the conversion from the power bank's battery to wireless transmission and then again during reception and conversion within your phone. A 35-45% loss is industry-standard for efficient wireless charging. Therefore, a 5,000mAh power bank effectively delivers approximately 2,750mAh to 3,250mAh of actual power to your iPhone's battery.
Q: Can I use this with a non-MagSafe case?
A: For optimal performance, you need a case that is either MagSafe-compatible or very thin and non-metallic. Standard thick cases will significantly reduce charging efficiency and may prevent the magnets from holding securely. Metal cases will block charging entirely.
