iPhone 11 Charging Test. Which USB PD Charger is better?
iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max have been officially released for a while. As we all know, the Pro model comes with an 18W PD charger and a USB-C to Lightning fast charging cable. For the basic iPhone model 11, although he also supports the USB PD fast charging, but it still comes with the ancestral 5V1A charging kit.
It is very easy for Apple to standardize the phone with the 18W PD charger. Is it really unnecessary to give the iPhone 11 a quick charger? What is the benefit will the iPhone 11 user buy a PD charger at her own expense? Today, Inviolabs will answer if this is necessary.
At the beginning, it is sure that the iPhone 11 supports the USB PD fast charging function, and the maximum power is as high as 22W+ for the two Pro models. Since it supports PD fast charge, let's do the PD fast charger and a 5W charger comparison now.
In this testing, there are three groups, which are: the iPhone 11 comes with the 5W charger, the iPhone 11 Pro comes with the 18W PD charger, and the Apple 30W PD charger.
First is the charging process of the 5W charger. From record, it is charging at 5.05V/0.97A, 4.9W.
The charging process of the iPhone 11 is very stable. It is connected to the charger for a handshake of 5W, which lasts for 2 hours and 44 minutes, and then enters the constant voltage phase, and the power continues to decrease. It dropped to below 0.1W until 3 hours and 45 minutes, till it fully charged.
5W charger which comes with iPhone 11 can only charge 16% in half an hour. And only charge 32% in one hour. It takes 3 hours and 45 minutes to fully fill. It is too slow.
It is not surprised that the iPhone 11's 5W charging speed is so slow, nearly 4 hours. Fortunately the phone supports USB PD fast charge, let us put on the iPhone 11 Pro standard 18W PD fast charge kit for testing.Now that the phone is charging at 9.02V/1.95A and 17.62W.
After the 18W charger on, the battery is charged at 7.5W. After the phone is automatically turned on for 53 seconds, the PD is quickly charged and the power immediately climbs to about 17.5W. It began to gradually decrease until 23 minutes, and entered the constant voltage phase at 1 hour and 8 minutes. The power continued to decrease until the power dropped below 0.1W at 2 hours and 16 minutes till the iPhone 11 was fully charged.
The 18W PD speed is hugely increased, charging 53% for half an hour, 80% for one hour, and only 2 hours and 16 minutes for full charge.
As we mentioned earlier, the iPhone 11's PD fast charge power can be up to 22W. Is it faster to charge the phone with a higher power PD charger? Let's test with the Apple 30W PD charger. Now the phone is charging at 8.91V/2.53A, 22.59W.
Charging with a 30W PD charger is very similar to 18W, and the peak power is increased to about 22W. After the charger is on, the battery is charged with 7.5W power until the phone is automatically on until 3 minutes and 21 seconds. After the power is turned on, the PD protocol is fast-charged. At this time, the charging power reaches 20W or more, and slowly rises. At 17 minutes, the maximum power of this charge is 21.6W, and then the power begins to gradually decrease. When it enters the constant voltage phase at 1 hour and 5 minutes, the power is continuously reduced. Until 2 hours and 16 minutes, the power drops below 0.1W, and the mobile phone is fully charged.
30W PD fast charging and the 18W PD fast charging is almost the same, charging 55% in half an hour, charging 84% in one hour, and fully charging 2 hours and 16 minutes.
Finally, we compare the three sets of data of this test together.
From the comparison curve, it clearly that the PD fast charger speed is much higher than that of 5W original charger, more than 50% in 30 minutes, charging more than 80% in one hour, using original 5W charger takes half an hour to charge 16%, and it reaches 32% in an hour. Using the PD fast charger for iPhone 11 is one-and-a-half-hour shorter than 5W.
Compared with the 30W and the 18W, they have a difference of 2 minutes. And they almost using the same time to fully charged. The difference is small, 30W is still faster than 18W, although it is only a little.
Summary:
"If you are going to use/using the iPhone 11, throw away the original 5W charger.
A faster USB PD charger is needed." (Click to Tweet this)
1, iPhone 11 original comes standard with 5W charger is very slow, it is very necessary to purchase PD charger and MFi USB-C to Lightning cable at your own expense.
2, iPhone 11 using PD fast charge, measured in half an hour can be charged with more than 50% of the power, killing 5W charger of 16% for half an hour.
3, iPhone 11/iPhone 11 pro can fast charge power up to 22W +, 30W PD charger and 18W PD charger, the speed gap is about a few percentage points, the pursuit of cost-effective users can purchase 18W PD charger. Users with higher demand can increase their budget to purchase 30W PD charger. In addition to better service for iPhone 11, it can also be used for iPad, thin and light notebooks, etc.
So in order to achieve fast charging, we need a charger that can support fast charging. As mentioned above, iPhone and iPad only support the PD fast charge protocol, but not other protocols such as Qualcomm's QC, so we need to be clear that charging devices need to support the PD protocol.
Next, is the consideration of max power out. For the iPhone, according to the test, the 18W charging speed has met daily needs, considering daily portability and compatibility. Inviolabs recommends using an 18W dual port charger. Provide dual PD and QC interface, full compatibility.
For iPad or macbook devices, it supports charging power of more than 30W. Inviolabs recommends a 60W dual port charging device. Dual port high power input.
Finally, we need to choose a cable. What we need here is a USB-C to Lightning cable, which is usually referred to as CtoL. Apple only support the USB-C to Lightning cable for fast charge. Be aware the this cable has Apple's MFi certification.
Inviolabs offers the following options: DurableLine and DurableLine Plus series. If you using the cables travelling, Inviolabs recommend to use the Plus series. We have prepared a storage bag for you. The nylon braided thread brings better durability. We also recommend you have 2 other DurableLine cables, one in the office another at home.
