Over the last couple of Years, Smartphones like those running on the Android Operating Systems (OS) have been coming up with various Fast Charging Systems, and I just wanted to write about my personal experiences with them.
Before Fast Charging Tech
Before these Fast Chargers started coming up as regular features on Android units, it usually took a long time to charge Smartphone Batteries, as much as 4-5 hours on some Smartphones that I owned.
For example, my old Sony Xperia T2 Ultra back in 2015 took around 4-5 hours to fully charge its 3,000 Lithium Ion (Li-Ion) 3,000 mAh Battery from 0 or close to 0 to 100% depending on whether the unit is on .
My older Cherry Mobile S320 Titan TV back in 2013 was even worst, taking around 5 hours with the unit on to charge its 2,500 mAh Li-Ion Battery. The fastest charging unit I had before these Fast Charging Technology came up was with my Samsung Galaxy E7 back in 2016 which took only 2 hours and 15 minutes to charge its 2,950 mAh Li-Ion Battery.
Fast Charging Tech
My first experience with Fast Chargers was with the 20W Voltage Open Loop Multi-step Constant-Current Charging (VOOC) on my Oppo F9 back in 2018 which only took around 1 hour and 30 minutes to charge its 3,000 mAh Lithium-Polymer (Li-Po) battery from 0 to 100% with the unit turned off which I thought was absolutely fantastic.
When I changed to the Huawei P30 Lite in 2019, I was a bit disappointed because its 18W Fast Charge System took longer at around 2 hours to charge its 3,340 mAh Li-Po Battery from near 0% to 100% with the unit on.
Right now my Phone is the Realme 6 which I bought recently, and it uses the 30W Flash Charge 4.0 VOOC technology which charges its Battery from 2% to 100% in only 1 hour and 15 minutes.
What I find more impressive is the fact that it has a higher capacity Battery than the F9 or P30 Lite with its 4,300 mAh capacity Li-Po Battery.
What I love about this fast charging system is that I go over and charge the Phone, do something, and more often than not when I finish and come back to the Phone, it is already fully charged.
The Future
Higher end Phones now have even faster 65W Fast Charging technology which I expect to trickle down to lower end Phones by next Year (2021). My expectation is that it will be able to fully charge phones from near 0% to 100% with the unit on in around 45 minutes.
Even faster 125W Chargers are already available now on high end Smartphones that enable charging within just 15-20 minutes, I expect these to trickle down to lower end Phones in a couple of Years.
I think that within 5 Years, we will be able to see the Charging Technology that can complete Phone Charging to within just 5 minutes.
