If you are one of those people who feel unhappy about the charging capability of your iPhone or iPad, this post is definitely for you. It is indeed a depressing note that while Android manufacturers progressively equip their flagship smartphones with fast-charging ability, iPhone on the other hand takes forever in charging up fully to a hundred percent. You will even face a much slower than usual charging experience when you are a kind of person who can’t get their hands off their phone while it is tethered to the wall.

In today’s post, we will be giving you some tips on how to make your iPhone charge faster.

Switching to Airplane Mode

This is the simplest but yet effective way to charge your iPhone marginally faster than the normal time it takes for you to complete a 100% battery charge. One way to enable this feature is by swiping up from the bottom of the screen to bring up Control Center and then tap the Airplane Mode toggle icon to enable Airplane Mode. Another way is by going to the Settings → Airplane Mode and enabling the toggle button.

Tip: Charge iPhone using Airplane Mode

Turning on Airplane Mode means that all the radios on your phone such as Wi-Fi, cellular signal and Bluetooth will be turned off. Doing this will not only stop the radios from consuming power when in use but also completely disables the network access on your phone. Without the network access, your phone will not be performing background activities such as checking new emails, sending and receiving messages or calls, iCloud sync and other notifications which also consumes power by making the phone’s screen to light up. You can tap the Airplane Mode toggle again to turn it off whenever you are finished charging your device.

Leave your phone off

This tip can obviously mean that you need to completely turn your phone off which saves you a considerable amount of time on having your phone fully charged. In case you don’t like the idea, leaving your phone off can also mean that you should avoid using it while it’s plugged in and charging. In this manner, you’re preventing its need for power to operate the screen, motion sensors and continuous functions that consume battery while it’s being charged.

Temperature is a significant factor

Not everyone is giving extra precautions when it comes to charging their phones on places where it can be susceptible to high temperature like inside the car or on top of bed. It is basically important to keep the phone cool and letting it get a good ventilation for air to help it charge faster. If you notice that your device gets hot while charging, another good practice would be taking off your iPhone’s case to avoid generating excess heat, which can affect the battery capacity.

Use an iPad charger

There’s always a rising question on whether it is safe to use an iPad charger having 10-12 Watts to charge an iPhone or does charging the iPhone with a more potent charger could be overpowering and can cause damage. At first, one might think that using an iPad or a much more powerful charger can damage an iPhone and harm its battery.

The iPhone charger has the rating of 5 volts with 1.0 amps and 5 Watts power while the iPad charger comes with rating of 5.1 volts with 2.1 amps and 10-12 Watts power. Clearly you can see that although both have the same voltage, iPad charger can supply more current and power than what the regular iPhone charger can. Since both bricks have the same voltage, there’s technically no problem charging an iPhone with a charger that can supply more current than the device needs. Knowing that current is supplied on demand, the iPhone charging circuits will only take what it can handle and not what is supplied.

Therefore, we can conclude that the extra power supplied by the iPad charger can give the iPhone the capability to charge faster. Apple also has on its page the compatibility list for the 12 Watts power adapter to support this conclusion.

I have personally been using my iPad charger since my iPhone 5 up to my iPhone 6S Plus and even on my iPhone 3GS. It truly makes the charging faster and has no negative effects on my devices.

Giving your battery a good maintenance

Apple uses lithium-ion batteries on its devices, which means you can charge your device whenever you want without the need to let it drain to 0% before charging. Apple batteries are known to work in charge cycles.

One discharge cycle means using all your battery’s capacity charge but not necessarily all at once. A good example is when you have use 35% of your battery’s capacity one day, then fully charged it 100% overnight. If you perform the same and use 65% the next day, that two days will have a total of 100% discharge and would be counted as one discharge cycle.

Performing a full battery discharges (using your device until it turns off in 0%) frequently is not a good practice because it stresses the battery a lot and can even damage it. It is recommended to charge your iPhone whenever it reaches the 20%-30% mark instead of letting it power off itself upon reaching 0%.

However, it is recommended that you perform a full cycle once you have already performed 30 partial discharge cycles or at least once a month to calibrate your battery and make sure it has the longest life possible. It is important to calibrate your battery so it will have the accuracy in letting you know its current capacity. Full cycle means that you need to let your device power off once it reaches 0%, then charging it at full 100% capacity in just one charge.
