From the iPhone 1st generation (2007) to the new iPhone 11 Series (2019), Apple has released 24 iPhones in the past 13 years. The iPhone 11 has made huge improvements on previous iPhones, such as from 3.5-inch small screens to 6.5-inch full screens, from 128M memory to 4G large memory, etc. Today, we will talk about the history of iPhone battery and charging technology over the last 13 years.
Trust me, the history won’t be as boring as you think (Although it always does), instead, it will be very simple and funny like a trip to Hawaii, let us start traveling :).
No more gossip, let’s get to the point.
1. iPhone Battery Capacity
The iPhone 1st generation 2007 was equipped with the detachable battery, it is only 1030mAh. People can only use itself 16 APPs (Apple Store has not online yet), and the small 3.5-inch display screen, so the 1030mAh battery was still enough for daily use.
However, in the last 5 years, the smartphone became the way most people surf the web, online shopping, social media, online tasking, especially, mobile phone usage has surpassed desktop usage in 2018. So the smartphone battery capacity is also considered as one of the main factors when customers are choosing new smartphones. Therefore, almost every new iPhone has been constantly increasing battery capacity, so the iPhone 11 Pro Max battery capacity has increased to 3969Ah, which is in the biggest battery in iPhone history.
2. iPhone Charging Speed
In terms of charging speed, the iPhone has undergone several changes. The earliest iPhone used the 5W BC1.2 protocol, it doesn’t need too much time to charge their iPhone because the older iPhones battery capacity is not big (About 1200mAh), so the 5W charging technology has been adopted until iPhone 5S. But with the arrival of the big-screen iPhone 6 Plus, its battery capacity was increased to 2915mAh, iPhone developed a 2.1A charging protocol that supports a larger charging current to reduce charging time.
Later, from the iPhone 8, iPhone supports the PD fast charging technology, iPhone 8 supports 12W charging, iPhone 8 Plus and above models (including iPhone 11 Series in 2019) support 18W fast charging; meanwhile, iPhone 8 and above models also support 7.5W Qi wireless charging protocol.
3. iPhone Power Adapter and Charging Cable
iPhone 4s and previous versions have been using 30-pin to USB cable.
Later, iPhone 5 changed to 8-pin to USB Cable (Also named as Lightning to USB cable), and added MFi (Made for iPhone/iPod/iPad) certification, but iPhone was still equipped with the 5W USB power adapter.
Until 2019, Apple released the new iPhone 11 series and the 18W PD fast charging kit (USB-C to Lightning cable + 18W USB C power adapter) is standard on the iPhone11 Pro. The iPhone 11 Pro can be charged for 50% just in 30 minutes. The speed is much faster than before.
That is all the iPhone charging history, thank you for taking the time to stop by.
