Why Is My iPhone Battery Draining So Fast?

  • 5 min read

iPhone battery capacity is growing, but iOS is not becoming more energy-optimized. Therefore, one of the hottest topics among Apple smartphone users is still related to the problem of quick discharging of the iPhone battery. In this article, we give you the reasons why your iPhone battery drains fast and ways you can extend its life.

iPhone Battery Draining So Fast

About iPhone batteries

All current Apple devices use a lithium-ion battery. Compared to traditional batteries such as nickel-metal hydride batteries, they have a number of advantages. Lithium-ion batteries are lighter, have a higher capacity and a short charging time, and most importantly, they are durable. The last statement is true, provided that the batteries are used correctly.

  • Reasons why your iPhone battery drains fast

  1. Push notifications from apps
Push notifications consume a lot of battery. To send notifications, a process related to the application needs to consult a server very regularly. This operation requires energy. In addition, these notifications are often unnecessary. Therefore, you can find the apps with the least useful notifications, and turn them off to save battery. To deactivate these notifications, go to settings > Notifications, and tap the unnecessary apps to turn off notification.
  1. Background app refreshing
The more applications on your iPhone that turn to the Internet for any information, the faster the smartphone is discharged. Therefore, the best thing is to turn off background applications. To do this, go to Settings > General > Background app refresh, and tap the applications you want to disable.
  1. Apps using geolocation services
A huge number of applications use the iPhone's location services, and quite often in vain. This, in turn, drains and affects your iPhone battery health. However, you don't have to disable geolocation services completely, but it is worth forbidding specific applications to use the function to increase the battery life. Go to Settings > Privacy, select the application that should not be able to use geolocation services, and click "Never." Go through the entire list of installed applications and leave only important applications, such as navigators.
  1. Weak signal
When the iPhone cannot establish a stable connection to the cellular network, it starts sending signals to the carrier over and over again. The phone spends a lot of effort on this operation, and also, the battery charge. Airplane mode allows you to prevent the iPhone from continuously sending signals to the carrier when the connection is poor.
  1. Automatic Wi-Fi search
By default, the iPhone is constantly in the search mode for available wireless networks, which most often you do not need. Scanning influences the battery charge very strongly. Fortunately, you can turn off automatic scans for Wi-Fi networks. To do this, go to the Setting, click on the Wi-Fi menu and switch the "Request to connect" switch to the inactive position.
  1. Airdrop

Airdrop makes it easy to share files between Apple devices, but not everyone uses it. If you also don't use Airdrop, feel free to open the settings, click on Airdrop, and select "Receive off" For the function to stop wasting your battery power.

  • How to extend your iPhone battery life

There are a few basic rules that you can follow to significantly extend the life of your iPhone's battery.

How to extend your iPhone battery life

  1. Do not completely discharge the battery
One of the features of lithium-ion batteries is the almost complete absence of the so-called memory effect. This concept means a reversible loss of capacity that occurs when the charging mode is violated, in particular, when charging an incompletely discharged battery. Since the iPhone battery has almost no memory effect, it is highly recommended to charge the smartphone before it turns off due to a lack of charge. More specifically, it is necessary to connect the iPhone to the charger when the battery level drops below 10-20%.
  1. Avoid overheating and hypothermia

Heat and cold are the worst enemies of lithium-ion batteries. Overheating and over-cooling the iPhone can significantly reduce the battery capacity of your phone, so you should never keep it in adverse conditions.

But at what temperature does the battery get bad? Surprisingly to many, the ideal temperature for an iPhone battery is between 16 and 22 degrees. This is confirmed by numerous studies of lithium-ion batteries, including those carried out by Apple. The optimal temperature for using the iPhone is up to 30 degrees.

  1. Use the certified charger

Not all cables and chargers are the same. There are different voltages, amperes, overload protection, and other differences that make not all chargers the same. That's why it's wise to always use Apple-certified chargers that come with MFi (Made For iPhone, iPad, or iPod) badge.

MFi certified chargers are those approved by Apple, which analyzes them and guarantees that they follow all the necessary quality standards. They also have an internal chip that is updated along with iOS, thus maintaining operation in all versions. You can check whether your charging cable is MFi-certified here. And make sure to use certified chargers manufactured by trusted brand like UNBREAKcableand Syncwire.

  1. Calibrate iPhone battery

If you have decided to start firmly following (or are already following) the first tip, there is one more thing you need to know. Fully charging Li-ion batteries for a long time is just as harmful as continuously discharging to zero. Experts strongly recommend that you calibrate your iPhone every 3 to 4 months. Moreover, this must be done in a special way.

Step 1: completely discharge the battery
Step 2: leave your iPhone turned off for a few hours (ideally overnight)
Step 3: Connect the iPhone to the charger and leave it on for at least five hours. Even after the battery is 100% charged. It is best to turn off your iPhone while it is charging.

After completing this simple but time-consuming process, the iPhone battery is calibrated. It is advisable to perform this procedure every 3-4 months. Such a simple trick will allow you to reset the so-called upper and lower battery charge flags. This allows the iPhone to last longer on battery life and slows down the battery drain on its overall capacity.

  1. Charge iPhone without a case

iPhone cases are most often made of silicone or neoprene. These materials lead to additional heating of the body during charging, which can negatively affect battery capacity. Determining whether your case is detrimental to your phone is very simple. If you notice that your iPhone becomes very hot while charging, remove it from its case first.

Nowadays, we use our iPhone mobiles more. Precisely for this reason, the battery ends up not being enough to do everything. These tips can help you to lengthen your iPhone's battery life and eliminate the inconvenient problem of running out of battery in the middle of your day.
