Alright, so there can be several reasons why your smartphone is charging slowly, and most of it comes down to using the right charging technology that is compatible with your phone. However, there is more to it than that because smartphones have gotten considerably more powerful over recent years, and that has made it so that your phone burns away at your battery faster than ever.
In this guide, we’re covering why your phone may be charging slowly, discharging quickly, and what you can do about it.
Fast Charging is a Must
Okay, you’re going to need to use fast charging with your smartphone, and at the time of writing this article in 2021, there are quite a few fast charging technologies that could be used for your smartphone, and it doesn’t matter if it’s an Android phone or an iPhone. We recommended using a USB-C Power Delivery charger to fast charge your phone as nearly every single Android smartphone for the past four or five years is one using a USB-C port to charge, and even if you have an iPhone, then you can use a Lightning to USB-C cable to fast charge your iPhone.
Programmable Power Supply for newer model Samsung phones
The base of Power Delivery fast charging for smartphones is 18W, and most phones are capable of that fast charging speed. However, for newer phones such as the Samsung Galaxy S20 and the Galaxy S21 they are compatible with Programmable Power Supply (PPS), and this is more of a proprietary fast charging that select few chargers feature; that said, with a PPS fast charging, you can charge these newer model Samsung phones at 25W. Just in case you’re wondering where you purchase a PPS charger from, Charger Harbor’s SAIL01 uses a 25W PPS charge rate via USB-C 2 for Samsung phones.
When it comes to fast charging USB-C smartphones from a USB-C port, you‘re going to need to use a USB-C to USB-C cable.
Quick Charge is still here
If you have an Android smartphone, you may also be able to use a Quick Charge charger, and Quick Charge is mainly used with USB-A ports but may also be present with USB-C ports. If you have an Android smartphone that uses a Micro-USB port to charge from, then you can likely use a USB-A Quick Charge port to fast charge it.
Yes. iPhones are Power Delivery compatible
With the release of the iPhone X and the iPhone 8, that’s when the iPhone finally became Power Delivery fast charging compatible because, before that, you could only charge an iPhone at 10W. Now, if you have newer models, you can use a USB-C Power Delivery charger with a Lightning to USB-C cable to charge the iPhone. Yes, you will specifically need a Lightning to USB-C cable because the iPhone still uses a Lightning port.
Also, even newer iPhone models such as the iPhone 12 can now charge at 20W.
What about Wireless Charging?
Wireless charging at this point is not very fast. However, a few smartphones do use their own fast wireless chargers that far surpass regular wireless chargers, one of these cases being the OnePlus’ Warp Charge 50 wireless charger that can charge the phone at 50W. That’s an incredible wireless charging speed.
However, for the more mainstream phones that are wireless charging compatible, you’re normally going to be getting only 5W, 10W, or 15W. This is the case for most Android smartphones as many of them can only charge at 5W via a wireless charger, and Samsung phones will charge at 10W, and LG phones will charge at 15W. iPhones can charge at 7.5W with a wireless charger. That said, you have to get a wireless charger that can output those charging rates.
Overall, wireless charging is not the best thing to go with if you want fast charging.
What’s going on with your Phone
It’s not always about fast charging your phone, though; you also have to consider what’s happening with your phone. Many modern phones now use higher refresh rate displays, and if you’re combining the higher refresh rate while using your phone and charging it, your phone won’t be fast charging. That’s right; most phones won’t actually fast charge, or at least the fast charging won’t be used to its full potential because the charge rate is lowered to prevent overheating.
Also, older batteries tend to charge slower because the Lithium-Ion battery degrades over time, and you may find that your battery drains faster than a few years ago. If that’s the case, you may think that getting a battery replaced may be a good idea, but it’s not. Battery replacement will basically cost the same as getting a new phone.
You may have many apps running in the background; however, even though this is something that many articles mention, most modern smartphones can run many apps simultaneously, and it does not interfere with fast charging as you may think.
We will say that the cable that you use to charge your smartphone is essential to ensure that your phone can charge at its fastest speed. Low-quality cables may not deliver ample charging power, and therefore your phone will charge at a slower speed. To ensure that your phone is fast charging use good quality cable; we recommend purchasing cables from reputable brands.
