The Dell XPS 9640-7097SLV-PUS is a premium laptop designed for professionals, creators, students, and users who need powerful performance in a slim and portable design. With its high-performance processor, advanced display, and productivity features, the laptop is widely used for work, entertainment, and creative tasks.

However, after long-term use, the built-in battery may gradually lose its original capacity. A degraded battery can cause problems such as short battery life, unexpected shutdowns, slow charging, or the inability to hold a charge.

The RWFFJ 8504mAh Replacement Battery is designed as a compatible replacement solution for the Dell XPS9640-7097SLV-PUS, helping restore battery performance and extend the usable life of the laptop.

Why Does Dell XPS 9640 Battery Life Become Shorter?

Laptop batteries are consumable components. After many charging cycles, lithium-ion batteries naturally lose their ability to store energy.

Common signs of battery aging include:

• Battery drains much faster than before
• Laptop needs frequent charging
• Battery percentage drops suddenly
• Laptop shuts down without warning
• Reduced working time away from the charger

If your Dell XPS 9640 battery no longer provides enough runtime, replacing the old battery with an RWFFJ 8504mAh battery replacement can help restore longer usage time.

Common Reasons for Fast Battery Drain on Dell XPS 9640

1. Heavy Workloads and High Performance Usage

The Dell XPS 9640 is often used for demanding tasks, including:

• Video editing
• 3D rendering
• Programming
• Graphic design
• Large file processing
• Professional applications

These activities require more power from the CPU, GPU, memory, and cooling system, causing faster battery consumption.

A new RWFFJ replacement battery provides stable power for intensive workloads.

2. High Display Brightness and Multimedia Usage

The display is one of the largest power consumers in modern laptops.

Battery drain can increase when using:

• Maximum screen brightness
• High-resolution video playback
• Long online meetings
• External monitors
• Streaming platforms

To improve battery life temporarily:

• Reduce screen brightness
• Close unused applications
• Enable battery-saving modes
• Disconnect unnecessary devices

If battery performance remains poor, the original battery may have reached the end of its lifespan.

3. Background Applications and System Processes

Many programs continue running in the background, consuming energy.

Examples include:

• Cloud synchronization
• Antivirus scanning
• Browser tabs
• Software updates
• Communication applications

A worn battery may not provide enough capacity to support normal daily usage.

Dell XPS 9640 Battery Not Charging? Possible Causes and Solutions

If your Dell XPS9640 does not charge properly, the issue may come from the charger, charging port, or internal battery.

1. Check the Charger and Power Adapter

Before replacing the battery, check:

• Whether the charger works correctly
• Whether the power adapter provides stable power
• Whether the laptop recognizes the charger

A faulty charger may create symptoms similar to a damaged battery.

2. Inspect the Charging Port

Dust or loose connections can affect charging performance.

Recommended checks:

• Clean the charging port carefully
• Make sure the connector is firmly connected
• Try another compatible charger if available

3. Battery Cannot Store Power

If the laptop shows charging but quickly loses power after unplugging, the battery may be degraded.

Typical symptoms include:

• Battery reaches 100% but drains quickly
• Laptop turns off immediately after disconnecting power
• Charging stops unexpectedly
• Battery percentage changes irregularly

In this situation, replacing the battery with an RWFFJ Battery Replacement can solve problems caused by reduced battery capacity.
