Is fast charging harmful to your iPhone

Fast charging is a very convenient thing, but at the same time, the technology raises many questions in terms of the effect on the smartphone’s battery. Not so long ago, I already wrote about my iPhone SE 2020 – I noticed that over the same period of time, the iPhone XR had much more battery capacity. I have been actively promoting the theory that fast charging is to blame, even though Apple allows it to be used in the 2020 iPhone SE. It’s time to figure out if fast charging is harmful or not? Who is to blame for the battery capacity dropping so quickly?

Is Fast Charging Harmful to iPhone? Let’s try to figure it out

How to properly charge your smartphone

Once, when I was buying a new iPhone, a friend of mine said that it was necessary to properly charge the new device. Immediately after purchase, you need to charge it to 100%, then use it until the battery is completely discharged and charge it fully again. And so three times in a row. In the future, you need to follow certain rules when charging a smartphone, for example, try to adhere to not allowing a complete discharge. It’s best to charge your iPhone more often and keep the charge between 40% and 80%. Experts recommend not charging your device to 100%. There is an exception to the last rule – it is useful to discharge the phone once a month. whollyand then recharge to maximum.

Do not drain your iPhone completely, it is better to leave at least 10%

It may not be cheap, but I always use the original chargers. Thanks to the controllers installed in them, iPhone charging is smart and tries not to kill your battery. In non-original chargers, this is not the case, which can adversely affect the performance of the battery.

It is important to remember about nightly charging the iPhone – the battery will not receive an excess charge, because a special chip is simply will stop charging the smartphone 100%. But the phone is constantly running background processes that slowly drain the battery, and then the charger recharges it again – this increases wear and tear.

How fast charging works in iPhone

The fast charging process in the iPhone, according to the manufacturers, is absolutely safe. This function allows the battery to be supplied with an increased current value, and the capacity recovery process does not disrupt the battery operation even with frequent use. During charging, the device is charged at an accelerated rate of up to 50%, and then the normal charging mode is activated. The power is reduced until it reaches 80% – after charging it is carried out with a minimum current like a regular AC adapter.

To my regret, Apple and its fast charging are not to blame for the fact that the battery capacity dropped very quickly – you have only yourself to blame. The thing is that I regularly violate the rules for charging a smartphone. For example, I charge for 20-30 minutes and remove the phone from charging by 40-50% – such an undercharge will be considered a full cycle, so the battery capacity decreases. On average, iPhone lithium-ion batteries are rated for 500 charge cycles. If you calculate that, on average, I connect my iPhone 1-2 times a day, then at this rate my battery will live at best for another year.

On the other hand, an independent expert Eric Leamer claims that if you keep the charge in the region of 20-80%, then the number of cycles will increase. That is, if you charge up to 70%, then your battery will live much longer – almost 1200 cycles instead of 500! How should we relate to this statement? Probably it is worth listening and drawing conclusions.

It is worth noting that my iPhone SE has a small battery capacity, and I use it quite actively. That is, with high performance of the A13 processor, the conditional 70-80% of the charge is enough for a shorter amount of time. In addition, using a smartphone while charging is also not recommended, which I constantly neglect. It’s best to leave your iPhone alone for a while until the battery is fully charged. Do not agree?

Fast charging is very convenient, but it is important to follow the rules – then the battery will last a long time

In general, all the troubles associated with battery charging and decreasing capacity should only be blamed themselves… Apple recommends using only certified accessories that will not lead to overheating, remove the case from the smartphone, leave the smartphone alone if possible – we actively ignore these rules, and then we complain that the battery is not the same as six months ago. If fast charging was harmful to our smartphones, then, as my colleague Ivan Kuznetsov noted, the companies that produce them would have been sued long ago. This does not happen, which means that all the blame lies solely with us.
