New Wireless Standard

Wireless charging is supposed to be the easy option.

You put your phone down, walk away, and come back to more battery.

So when you leave an iPhone on a charger for half an hour and the battery percentage has barely moved, something feels wrong. Maybe the phone is warm. Maybe charging keeps starting and stopping. Maybe the charger worked perfectly yesterday but suddenly feels painfully slow today.

If you have ever searched “why is my wireless charger so slow?”, the answer is rarely as simple as “wireless charging is just slow.”

Charging speed depends on an entire chain: the phone, charger, power adapter, cable, case, alignment, temperature, battery level, and even what you are doing on the phone while it charges. One weak link can reduce the performance of everything else.

The good news is that many of these problems are easy to identify. And newer standards such as Qi2 are designed to remove one of the biggest variables in wireless charging: inconsistent alignment.

Here is what is actually happening when wireless charging feels slow, what you can fix, and where Qi2 makes a meaningful difference.
