Dark mode supports all Apple devices,including the apps that come with iPhone and iPad. At the same time, if third-party applications follow Apple's development principles, this model can also be supported.

How to manually enable Dark Mode in iOS 13?

iPhone X series: slide down from the upper right corner, pull down the control center, and long press [Display and Brightness].

iPhone 8/8P and Other iPhone series: slide up from the bottom, pull out the control center, and long press [Display and Brightness].


1. Enter "Settings", then select "Display and Brightness" to find the [Dark Mode], just check it. You can also slide up from the bottom to the control center, long press the brightness slider, and then press the icon in the lower left corner to switch.

2. iOS13 also supports automatic dark mode. You can choose to automatically enable the dark mode from sunset to sunrise, or set a custom schedule and select a specific time to enable a dark or bright appearance.

3. Dark mode also adds new options for wallpapers in iOS 13. After enabling dark mode, you can choose to automatically dim the theme wallpaper, which means that IOS will automatically darken the wallpaper to match the dark mode interface UI.

The dark mode of iOS13 has "delicate texture" instead of pure black.

The Benefits of Dark Mode IOS 13

The iOS 13 dark mode provides a new color scheme for iOS and APP, which is very suitable for use in dim environments and less damage to the eyes. It supports manual turn on, click the shortcut switch in the control center to quickly turn on/off the dark mode.

And iOS 13 dark mode supports user customization, users can set a specific time to turn dark mode on or off Whether you are using Mail, Books or Safari, the text will be displayed as white on a black background, making it easy to read in the dark.


It is worth mentioning that the new iOS 13 wallpaper is also optimized for dark mode. The API allows developers to use dark mode in third-party apps. iOS can make third-party apps use black themes, which is the biggest advantage of iOS 13.

Does Dark Mode Saves Battery Life?

Using dark mode usually also extends the battery life of the iPhone because it requires less power to light the screen.

Test the power consumption of the same model in normal mode and dark mode.

After five hours and ten minutes of testing, the iPhone 7 has a remaining power of 23%, but 25% in dark mode, and 0% of iPhone X in normal mode, and 74% in dark mode.

We already know that the dark mode is mainly for OLED screens. (The iPhone X using the OLED screen consumes very little power in the dark mode). So, the iPhone 7 test results show that the power consumption is basically the same in normal mode and dark mode.


Dark mode will greatly increase the battery life of iPhone X / Xs / Xs Max. The battery life problem has always been the biggest pain point of iPhone. If you have iPhone X / Xs / Xs Max, you should not refuse the dark mode in iOS 13 that protect your eyes and saves battery.


Dark mode is one of many new features in iOS 13. We provide a guide about benefits of dark mode iOS 13 to help you make the most of the updates and the hidden features we have mentioned.

How to Test iPhone Signal Strength

You often travel to many places with mobile phone. You may have experienced in some remote areas, when you use a mobile phone to call, you often find that the signal is poor, or there is no signal at all. How to check the actual signal strength on your phone?


What is signal strength in mobile?

We see on the mobile phone screen that the stepped signal icon corresponds to the mobile phone signal strength, which corresponds to the"dBm" value. dBm is milliwatt decibel, which is a unit of signal strength commonly used in mobile phones. dBm is the power ratio of radio power per milliwatt in decibels. The -60dBm signal is almost perfect, while the-112dBm signal is a bad connection. dBm is calculated by the logarithm, so the dBm displayed on the mobile phone is generally negative number.

Generally speaking, if the dBm value displayed by the mobile phone is between -80 and -50, then the signal is normal. Can achieve basic communication and internet access. If the displayed value is lower than -90dbm, it is likely that there is a problem of being unable to talk.

-40 to -50 signal is near the base station;

The signal between -50 and -60 is very good;

Signals between -60 and -70 are good;

The signal is slightly weaker between -70 and -80;

Weak signal between -80 and -90;

Below -90 is the basic communication status.

In theory, the actual value of the mobile phone signal is the value displayed in the mobile phone system.


How to check mobile phone signal strength?

Most Android phones can check the signal strength of the phone through[Settings]-[About Phone]-[Status or Network] -SIM Card Information, as shown in the image below.


Android can use some third-party applications to evaluate signal strength.

Cellular-Z Android software for signal testing free download:

1. You can search Cellular-Z in APP store and Google Play;

2. Launch the application to view system and network information,including WLAN, cell location, network, network strength, data status, IP,phone type, etc. Mainly check the frequencies FREQUENCY and BAND.


How to test my iPhone signal strength?

We take iPhone XS as an example, the user can enter "*3001#12345#*" in the dial interface, then click the dial button.

Then click the "Serving Cell Meas" interface in the interface that opens.

Check the signal strength values of the "rsrp0" and"rsrp1" primary and secondary cards, respectively.

As shown in the figure below, the signal strength of the rsrp0 primary card of the iPhone XS is -106 dBm, and the signal strength of the secondary card of rsrp1 is -111dBm.


How to improve mobile signal strength?

In fact, the strength of the mobile phone signal is not only related to the mobile phone, but also can be affected by the following factors. First of all, the different positions of the signal transmission towers of different operators will also affect the signal strength. Secondly, the protective frame of the metal material, the iPhone case also affects the strength of the signal.The protective case of this material may become the killer of the mobile phone signal.

1. Use your iPhone in different locations

Observe how the signal changes according to location. If the signal changes periodically between locations, this is the main reason for the weak signal. In some remote or low-lying places, when you have a weak signal, you can better understand which direction you may go to get better coverage.

2. Change network operator

Using different network SIM cards in the same place may show different signal strengths. Selecting the network operator with a strong local signal is the most direct way.

The above is information about test signal strength on iPhone. In the basement or other areas with weak signals, choosing a signal amplifier is a good choice to enhance the mobile phone signal. GEMWON products also have accessories for iPhone and WIFI signal amplifier. If you need, you can contact us to buy popular electronic.

iPhone x Cracked Screen Repair

When i received second hand iphone x there were loads of scratches on the front screen and a few cracks. as you all probably know too is that iphone x screen replacements are pretty expensive because its been discontinued by apple so I’m trying to look for a way to hide the scratches.

How to do if iPhone X cracked screen replacement? Before buying a new screen to replace the broken screen, we need to confirm which part of the screen is broken in order to purchase the right accessories.


Part 1: iPhone x internal screen or external screen is damaged?

The screens of iphone and Android phones are divided into two layers, the internal screen is responsible for display, and the external screen is responsible for touch. If the screen is not responding after the screen is damaged, but the screen display is no problem,it means that the touch screen (Digitizer) of the phone is broken.

If the iphone front panel glass is sunken, a cracked iphone screen can cause cracks to widen. The phone's internal screen surface will also be scratched, so it is recommended that you replace the damaged iphone cracked touch glass screen as soon as possible.


Part 2: Screen appearance judges which part of the screen is broken?

If the screen of the iphone is broken, the display image of the iphone is not displayed, large colour blocks are displayed, the water ripple is constantly flashing, and the touch is normal, it means that the LCD screen of iphone is damaged.

If you see some black, yellow, and white spots on the screen, it also indicates a problem on the internal screen. At this time, we need to replace the iPhone screen as soon as possible to prevent cracks from expanding.

If the iphone has a crack on the screen, the iphone touch screen is not working or insensitive, and the mobile phone image display also has large coloured blocks or does not display, which means that both the internal and external screens of the iphone are broken. Then you may need to purchase a screen assembly to replace all the broken parts.

Part 3: iPhone X Teardown and Cracked Screen Repair

Separate iphone and screen:

1. Use a hexagonal screwdriver to unscrew the two hexagonal screws on the bottom of the iphone and remove the sim card holder.

2. After removing the screws, it is a very important step to open the iphone screen. iPhone X will have a circle of black waterproof adhesive to glue the screen and the phone body together. When we dismantle, pay attention to this circle of waterproof glue.

It is recommended to use a hair dryer to slightly heat, first pry a slit from the bottom two corners, and then use a spudger to slowly open the sides and top.

3. After swiping all the way, gently lift the screen from right to left.There are three buckles on the top of the iPhone. When we lift the screen, we open the bottom first, and then pull the screen down slightly to lift the entire screen. Note that you need to lift it from right to left.


4. Slightly slow down when the screen is lifted, there are cables inside. There are five screws with different lengths that need to be unscrewed after being opened. Put them in place and remember the corresponding positions.If the screws are installed in the wrong position, the top of the screen will burst when the screen is closed.


5. After unscrewing all the screws, lift off the gasket below.


6. Below the pad is the cable tie of the screen. Note that there are 3 cables here. The leftmost cable is glued. Let's open the two cables on the right first.

With the leftmost cable, we remove the glue that has stuck a little bit,and then lift the cable again.

Removing two battery cables can prevent functional problems after changing screens.

When the cable is lifted, the iphone is completely separated from the screen.


Replace the camera:

1. Unscrew the 2 screws on the camera with a Phillips screwdriver and place them.

2. Unscrew the camera after unscrewing the screws, take it from both sides, and do not touch the mirror of the camera.

3. After picking up the camera, there is a gasket underneath glued to the mobile phone to be removed. You need to slowly cut the glue from both sides to remove it.


4. Install the camera on the new screen, and place the spacers in the corresponding positions. Then put the camera up again and put it into the alignment position according to the screw hole alignment. Screw on the camera and the camera is installed.

Install screen:

Follow the disassembly steps to install all parts upside down.

1. Fasten the screen cable, and gently buckle the alignment position.Remember to buckle the battery cable.

2. Install the gasket on the screen and tighten the screws. The size of the screws varies. The corresponding screws must be installed in the corresponding positions. After tightening the screws, apply waterproof glue.


3. Perform a simple functional test before tightening the screws.

4. After the screen is fastened, screw in the 2 hexagonal screw at the bottom.

Next you need to test if the new iPhone x screen works. Face ID, light brightness adjustment, original colour display, and 3D touch are the important features.

My battery started some months ago draining real quick so i decided to buy a new one and change it myself. But the battery is still draining at the same speed, even on standby. This problem may leave you clueless, this article will help you solve iPhone battery that dies so fast after replacement.


Use original battery

Determine if the newly replaced battery is original. This problem may occur if the iPhone has a third-party battery installed. The battery hardware is incompatible or the battery quality is bad and iPhone overheating after battery replacement may cause the iPhone battery drain fast after replacing the new battery.

You can open [Settings], find[Battery] and click, check [Battery Health], check the current maximum capacity, enter the interface and click Battery Health. Tap anywhere in the list to change it from a percentage display to a breakdown of screen and background used by running applications. Close programs that are draining the iPhone battery.

How to reset iPhone?

If the iPhone battery is in good condition, reset the iPhone first to rule out drain fast caused by the conflict of phone program software.

Try to restore the factory settings.

If you want to keep the information on your iPhone, iPad, or iPod, create a backup.

Restore your device to factory settings.

Open iTunes on your installed Mac.

Connect iPhone to your computer.

If a message appears asking for your device password or asking you to "trust this computer," follow the steps that appear on your screen.

Click Restore [Device].

Your computer will then erase the contents of your device and install the latest iOS, iPad OS, or iPod software.

After restoring the factory settings, the iPhone will restart. You can now set it up as a new device.


Damaged or improperly installed batteries

A damaged or improperly installed battery is the root cause of the iPhone battery draining and getting hot.Please caution when installing or removing the iPhone's battery when replacing. Otherwise, you may break the small components on the circuit board near the battery. This can also cause short circuits and battery is damaged. The circuit board may be shorted in water, etc. This short circuit usually generates heat,so check for abnormal heat on the motherboard.

Use original Apple adapter

Make sure you are charging with an original Apple USB adapter. Use the original Apple adapter to charge your iPhone for a few cycles. This may help resolve iPhone battery drain issues. If your iPhone gets hot while charging, it indicates a problem with the charger. Try not to use car chargers, because the car may have unstable voltage during start up or shut down, which may cause rapid loss of battery power.


Avoid iPhone overheating

It is especially important to avoid leaving the device in an environment where the ambient temperature is higher than 35, otherwise the battery capacity may be permanently damaged.

Charging the device in a high temperature environment may further damage the device.When the battery exceeds the recommended temperature, the software may limit charging after the battery reaches 80%. Storage of the battery even in high temperature environments can cause irreparable damage.


Battery life decreases when using the device in very cold environments, but this isonly temporary. When the battery temperature returns to the normal, its performance will return to normal.

Perform iPhone DFU restore

Enter DFU mode to restore iPhone firmware, first turn off the phone, then connect to the computer

Open iTunes now,

After shutting down, press and hold the power button and HOME at the same time for about 10S,

The iPhone can enter DFU mode,

At this time, iTunes will pop up a prompt, you can choose "Update" or "Restore".

Select "Resume", agree to the agreement, it will start downloading the firmware, and automatically enter the recovery mode after the download is complete.


The Bottom Line:

After all the above solutions, if replaced iPhone 6 battery still dying, it is necessary to get after-sales shop to check whether the motherboard has a problem. If there is an Apple store (or an authorized repair shop) to replace your iPhone battery, contact them to tell them about your problem and what you did to resolve it.

Make sure your iPhone is connected to Wi-Fi and connected to a charger to keep the iPhone charged.

step 1. Open the Settings on your iPhone → tap General.

Step 2. Now click on "Software Update".

Step 3. If prompted to update the system version.

Close iPhone color filter

iOS lets you filter the colors of your device. Depending on your settings, you can choose filters to enhance the display effect.

step 1. Open the Settings on your iOS device → tap General.

Step 2. Click Accessibility.

Step 3. Next, click on Display Accommodations → click on the color filter.


Step 4. Turn off the switch next to the color filter.


Reset to factory

If the above solution does not solve iPhone screen colors weird, you can reset the device to the factory default. It is to clear all existing settings including Wi-Fi passwords and account details.

Reset all settings on iPhone

step 1. Click Settings → click General.

Step 2. Click Reset → Click to reset all settings.

Step 3. Enter your iPhone passcode → Enter a restricted passcode and confirm.

Enable True Tone

When this feature is enabled, your iPhone display will automatically adapt to the surrounding lightning conditions, making the iPhone screen colors look consistent in different environments. Here's how to enable True Tone on iPhone X:

Go to settings.

Select display and brightness.

Then click the switch next to "True Tone" to enable the feature.


Setting your iPhone screen to short sleep can also help prevent screen aging issues. It is not recommended to set a longer auto-lock time.

To manage this setting, go to the Settings-> Display and Brightness-> Auto-Lock menu and adjust the time of inactivity to turn off the screen faster when the iPhone is idle.

Enable automatic brightness control

To do this, navigate to the Settings> General> Accessibility>Show Accommodation menu and tap to enable the feature.

In addition to automatic locking, you must avoid using high-contrast images. A high-contrast image is an image with a large contrast between dark and light, especially the charge between those afterimages may cause the afterimage portion of the iPhone screen looks weird.


If your iPhone X still displays screen burn-in, green lines, and other weird screen colors, you must consider it due to hardware issues, especially if this has affected your iPhone experience. You can also ask for some other specific suggestions or any advanced workarounds to try.

If your iPhone is still in warranty, then official after-sales repair is the best option. If unfortunately, the product is out of the warranty, then someone with repair experience can consider replacing the iPhone screen self. We can provide with iPhone repair parts you need, including iPhone screen and other flex cables.


The Bottom Line:

The troubleshooting tips in this article will help you resolve all screen issues on your device, including iPhone green screen. I hope we can help you fix iPhone screen weird colors and lines.
