Apple battery life: How to check battery capacity and optimize performance (Sponsor)

Apple is a great choice if you value long-lasting, powerful batteries. The battery size and battery quality is an outstanding feature of all devices, the iPhone battery capacity is quite secretly eyed with envy by users of other brands. That's good, that's the way it should stay. Experience has shown that even the strongest battery may eventually weaken.

After all, you don't want to run out of juice if, for example, you're on the go in Maltese casinos or enjoys a few exciting rounds of online slots in casinos with a German license.

Where to check the battery: iPhone or iPad

What does battery capacity even mean? Let's start with the basics. It is the amount of energy stored in the battery. Incidentally, a battery and a rechargeable battery are the same in this context, so the question could also be: What does battery capacity mean?

The answer for a certain iPhone battery capacity must always be a number in milliamp hours (mAh) because it is the amount of energy that can be stored.

The filling level influences the running time

The battery life is the time between two charges. Energy is delivered to the device gradually, with the rate determining when the battery level will drop to zero. Then the device has to be connected to the charging cable and recharged with new energy. Don't confuse battery life with lifespan. This is only expired when the battery irrevocably blesses the time.

To check the battery capacity, you only need to look at the manufacturer's information on the device. You can find these online if you can't find the information leaflet that came with your iPhone or iPad.

For information about battery consumption, go directly to “Settings” on your device and then to “Battery”. There you will find detailed information about which functions and apps suck the most energy from the battery.

You can see this from the read data

The battery status lets you see which apps are draining your battery in the background while you're not actively using them at all. So you already have the explanation why you have to constantly go to the charger despite sufficient battery sizes. You can deactivate or remove many apps based on this knowledge.

  • You can turn off automatic updates for unnecessary apps in the settings menu
  • At this point, you can turn off location services right away
  • Turn off annoying push notifications so your iPhone doesn't drain your iPhone battery with lock screen interruptions
  • In the battery menu you can also find out if and when your iPhone searched for network reception (searching also drains the battery or consumes energy)
You can see the battery usage in the iPhone under Settings → Battery.
You can see the battery usage in the iPhone under Settings → Battery.

Save your capacity for important things

By analyzing the energy consumption, you will know how much unnecessary battery capacity your iPhone has used so far. Now you can think about how to extend the runtime with countermeasures.

  • Eliminate apps you never use
  • If you're in areas with poor reception and don't need any reception at all, turn on Airplane mode
  • In general, you can save a lot of energy with the flight mode, so you could get used to switching it on regularly (e.g. during working hours when you are not using the iPhone).
  • Another energy-saving measure is reducing the display brightness

Important note for correct charging

Never charge an iPhone via USB on a computer when it is off or in sleep mode. This can lead to the battery being discharged and the charging capacity of the iPhone not being reached. When charging your mobile device, always plug in your MacBook or PC and make sure it doesn't go to sleep.

If you want to make full use of your iPhone battery capacity and maintain or improve the existing battery status of the iPhone, simply follow the tips below:

  2. Avoid exposing the device to intense heat or extreme cold.
  3. Take the device out of the case when charging, as some cell phone cases lead to overheating and battery drain.
  4. If you are going to leave the device unused for a longer period of time, store it at room temperature in a half-charged state (recharge it to 6% again after about 50 months if necessary).
  5. Switch to auto-brightness or generally throttle the display brightness if that is more comfortable for you.
  6. Use WiFi instead of mobile data.
  7. Put the device in power saving mode.
