Why Does My Phone Hang Up After Four Hours?

Automatic session timeouts, phone system settings, and internet issues can disconnect the calls. Generally, some call disconnections are set by the carrier itself to prevent network overloads and resource management issues for optimal performance.

Mobile carriers have a certain call time limit to avoid network overload for fair usage, which causes calls to hang up automatically. Some prepaid and "unlimited" calling plans have hidden limits or fair usage policies to manage network traffic efficiently.

Phones and devices can overheat after running many applications continuously for several hours. It may cause the phone to hang up the call or restart to cool down automatically, generally protecting and preventing internal damage.

Poor telecom networks caused by bad weather or unavoidable system issues from the provider itself also interrupt the calls. For VoIP calls, an unstable data or wifi connection drops calls unexpectedly.

Generally, VoIP software uses built-in call time limits to manage system load from excessive resource use. Due to internal software settings or provider service agreements, certain apps may disconnect calls automatically after a predetermined time, such as 4 hours.

If you have installed an unverified or malware application on your phone, it may disrupt phone functionality and cause unusual device lagging. Malicious applications can overload your system's processes, causing disruptions such as unexpected call terminations.

One of the common causes of call hanging is due to insufficient storage space on your device. Your device needs free space to manage temporary files and operate smoothly. When device storage is occupied by images, software, documents, and files, mobile phones start lagging and struggle to perform well, often causing software to run slowly.

Multiple apps running in the background consume RAM (Random Access Memory) on your mobile device, which can lead to call hang-ups. Facebook, Instagram, Twitter, Threads, WhatsApp, and other social media and messaging apps use up to 300 MB of RAM while running in the background.

Software updates are regularly released for certain years in mobile phones, but as your device gets older, these updates eventually stop being released. Due to this, your operating system and apps may experience performance issues, resulting in a lack of support for the new version of the apps, which can cause the phone to hang up.

A battery is an essential factor in running your device; power drain and other battery-related issues can be a serious problem, causing phone calls to drop. Problems such as overheating, lagging, frequent device restarts, prolonged charging times, and sudden battery level changes are symptoms of battery drain.

If the hardware linked to your network and the internet, such as the SIM tray, modem chip, and cellular antenna, becomes damaged, then your phone hangs up randomly. Other hardware failure issues, such as the screen, motherboard, and processor, can also be the cause at times, so ensure your device's hardware is functioning correctly.

Whether it's a personal or business call, make sure your device is charged and has a strong network connection to prevent calls from hanging up.

• Strong Network Signal: Check for a good signal and relocate to a location with a better network signal where you can clearly hear the other person on the call.
• Phone Charged: Keep your phone charged and turn your battery optimization setting off; some devices might disconnect calls after certain battery limits.
• Software Updated: Keep your phone software updated to avoid issues with outdated applications.
• Remove Background Apps: Remove all the unnecessary apps running in the background, preventing your phone from overheating.
• Sufficient Balance: Ensure you have sufficient balance or data to carry the call for a certain time period. In some countries, phone calls can be paid for through a monthly subscription or payment plan.
• Check SIM card: Check your SIM card and ensure it is properly inserted and not damaged.
• Contact Carrier: If you suspect a network problem, contact your carrier.
• Proper Hardware Functionality: If you experience any issues with the performance of your hardware, visit a professional technician for diagnosis and repair. Ensure that you maintain your device in a timely manner.
• Battery Replacement: Replacing your battery is a straightforward way to resolve issues related to battery drainage and swelling.
• Unwanted File Removal: If you are facing storage issues, try removing duplicate and unwanted temporary files stored on your device.

If your calls consistently hang up after a specific time, it could be due to carrier-imposed call limits, device overheating, network issues, and software settings. To avoid call disconnections, ensure a strong signal, keep your phone charged and updated, close unnecessary apps, and check call duration limits.
