The first device to withhold the charging block was the iPhone. An approved, wired, 30-watt charging block for the most recent iPhone costs about $50. Then, if you want a wireless solution, that’s at least another $50.

Samsung has jumped on this bandwagon, too. Some of the company’s latest phones require you to purchase a charger separately. If you think you can successfully substitute any randomly chosen charger from Amazon, you’re mistaken. The Samsung website says: “Using third-party chargers may invalidate your warranty and cause damage.” Then you have another $35 expense for a fast-charge block.

At this point, other manufacturers are still supplying power chargers. The OnePlus 9 Pro has a proprietary Warp Charge technology that can get your phone charged from 10 percent to 80 percent in the blink of an eye with the included 65-watt charger. Such fast charging seems unbelievable, especially because the OnePlus 9 Pro 4,500 mAh battery is split in two (so you’re charging two batteries at once). But it’s true. The OnePlus 9 Pro also has a fast wireless charger that will fully charge a phone in 45 minutes. But that charger will cost you an extra $69.

Take the time to establish a phone charging strategy. Lithium-ion batteries don’t perform best if you drain them to the teens and then charge them to 100 percent. For the battery to remain long-lasting, charge it after it reaches 20 to 25 percent, and don’t allow it to charge past 80 percent. In other words: Do not leave your phone plugged into the charger overnight, and, if you plan to store the phone for a lengthy period, be sure it’s charged to at least 50 percent, to prevent degradation while turned off.
