The Portable Charger for iPhone 12 that You have to Consider

You have to bear in mind that the amount of mAh required to recharge a drained smartphone widely differs in regards to the brand and model of the device. Although iPhones are regarded as a status symbol, they require more mAh, which only means that they take longer to charge than a regular Android phone. With this being said—a portable charger for iPhone 12 is needed to prevent the device from draining whenever you are on the go.

However, if you have owned an iPhone before, you’ll know that the device is slightly meticulous when it comes to wall adaptor compatibility or any type of external accessories. And if you have these concerns for today, the blog I prepared will shed light on the issue and help you note the factors you need to understand about your iPhone 12’s battery capability.

So without further ado, let’s begin today’s discussion…

 The Portable Charger for iPhone 12 that You have to Consider

How Many mAh to Charge iPhone 12?

The mAh actually stands for milliampere-hour. It’s actually a unit of measure for electric currents. And it’s used to measure the electric currents being generated by a steady source to an outlet such as home appliances or portable gadgets, which includes your smartphones or tablets.

One thing you should take note that the required mAh of a device is equal to its battery capacity. So it's important to know the device's battery capacity before we decide how many mAh is needed for full charging. For example, the flagship iPhone 12 milliamp hours is 2,815 of battery capacity, which gives you an estimated 50% of charge in 30 minutes and a full 100% in 2 hours and 8 minutes, assuming that you’re using a 20W fast charger.

This means that the 2,815mAh battery capacity of the device is also the answer to how many mAh is needed to charge iPhone 12. This information together with what kind of charger you use gives insight into the expected duration of the device. As for the iPhone 12, it has an estimated usage of 8 hours and 25 minutes with a standard charger.

As you see, the average 8 hours may not be sufficient, especially if you commute daily. This may necessitate you to bring a portable charger for iPhone 12 wherever you go. But as mentioned, Apple’s device is a little picky when it comes to external accessories, especially if they’re not compatible.

And if you are searching for the most reliable and sturdy wall adapter, then my best recommendation is the Anker iPhone 12 charger. You can also consider a power bank for iPhone 12, like the Anker 521 magnetic battery, that’ll enable you to recharge on the go.

Battery Capacities of Different iPhone Models

Other varieties of the iPhone 12 model, like the iPhone 12 Pro 5G, oddly have a 2,815mAh but give longer battery life which is about 9 hours and 10 minutes. At the same time, the iPhone 12 Pro Max 5G has a 3,687mAh battery capacity that gives you about 10 hours and 55 minutes of power after charge.

With this information in mind—do not expect that the battery life of each model is equally superior. Each model is unique in features which include the battery capacity—the higher and more updated the phones are, the more advanced they are.

Is mAh the Higher the Better?

Milliampere hour basically indicates the amount of energy that a device can store. And what this means is that a phone with a high mAh is way better in battery life than those that have a lower mAh. As I have explained earlier, the mAh of the phone indicates the amount of energy it needs to complete a full charge cycle. In addition, it also tells you the amount of energy it can store on a single charge.

Therefore, a smartphone with a 3,000 mAh battery capacity tells you that it lasts longer in regards to usage compared to a 2,000 mAh smartphone. However, this doesn't mean a higher mAh smartphone is more excellent in every other part like taking photos or gaming. And the higher mAh smartphones may take longer to charge as well due to the needed energy to complete the charge.

One of the main problems with almost all iPhones is the battery capacity which necessitates you to always bring a portable charger for iPhone 12.
