Is Apple xs a dual card or a single card?

Iphonexs is a single card and does not support dual card dual standby. Foreign dual cards are different from domestic dual cards, mainly because we don't have a virtual card, so if we want to use dual cards, we must have two card slots, but the situation in foreign countries is different. We only need one card slot to realize dual card dual standby.

So for our domestic consumers, only iphonexs Max and iPhone XR are real dual-card dual standby, while iphonexs has only one card slot, so for us, it is still a single card.

Tips to extend the life of iPhone battery;

1. Develop a good habit of charging.

When Apple's mobile phone prompts that the battery is low, charge it in time to avoid automatic shutdown due to low battery. If the battery efficiency is less than 80%, please try to replace the battery.

2. Upgrade to the latest version of iOS 13.

Apple has added a function called "Optimizing Battery Charging" to iOS 13, which can intelligently learn and judge users' usage and charging habits, and make the charging process more balanced, thus slowing down the aging of the battery and improving the battery life to a certain extent.

How to View: The function of "Optimizing Battery Charging" can be viewed in Settings-Battery-Battery Health ~

3. The background application refresh is prohibited.

Since iOS 7, applications can use battery life when running in the background, and it does. You can see how long the application has been running in the background. If the application runs out of power when not in use, you can disable background application refresh to prevent it from running in the background. If the application consumes too much power, we can also choose to uninstall it!

4. Enable low battery mode

IOS 9 has added a "low power mode" function, which can make the phone more power-saving. When the low battery mode is enabled, your screen will be slightly dimmed, limiting background processes, slightly slowing down the processor, or reducing the energy required by the device during normal use.

How to operate: The easiest way to enable this function is to slide down from the upper right corner of the iPhone, and then click the battery icon. It can also be set in >; Battery > enable low power mode in low power mode.

5. Turn off some app push.

You know, some push notifications, application notifications, email reading notifications and so on. These will shorten the battery life, so if you want to make the battery life of iPhone longer, you'd better turn it off. You can edit each application and turn off notifications in Settings.
