Why is my Firestick very Slow? And Fix it

Devices like Firestick, Roku TV, or Apple TV are some of the many different devices available on the market right now that are gaining a lot of popularity lately. These are compact gadgets that directly plug into your TV’s HDMI port and connect to the internet via Wi-Fi or Ethernet cable. With that, they allow you to access various online services and apps on your TV, such as Netflix, YouTube, Amazon Prime Video, Disney Plus, and many more. These services offer you a huge library of movies, shows, documentaries, and other content that you can watch anytime you want. You can also use these devices to cast or mirror content from your smartphone, tablet, or laptop to your TV screen.

However, with advanced features, there are also some drawbacks to such devices. A lot of users encounter streaming devices getting slowed down after some time, which can hinder the performance of the device as well as affect your overall experience drastically. There can be many reasons behind a slow streaming device, such as a Fire Stick. But there are also some handy tricks that you can apply to regain the original performance of the device. In this guide, we are going to cover the same for Amazon’s Fire Stick which is one of the most popular streaming devices available on the market right now. You can also find step-by-step instructions for each of our tips so that you can easily test which option works out for you.

Reasons Behind Slow Fire Stick

A slow Fire Stick can be very frustrating, especially when you want to enjoy your favorite shows and movies on your TV. Generally, the user interface of a streaming device is designed to be user-friendly and requires a little navigation to find the content you need to watch. But, if the same is offering slow response or delayed input, it can get really annoying after a certain time. More importantly, you would want your streaming service to be fast, whether you are browsing the content or streaming it. And since most users use the remote, it would be a hassle if the device crashes after registering a lot of delayed inputs at once. To avoid that, you need to understand some aspects that can cause your Fire Stick to slow down after a certain time.

Insufficient storage space

Just like your smartphone, laptop, or computer, the Fire Stick also has a limited amount of internal storage space, which can fill up quickly if you install too many apps or download too much content. This affects the performance and speed of your device. And since Fire Sticks are compact devices, they do not offer exceedingly fast hardware. For instance, the 1st Gen Amazon Fire Stick in 2020 was powered by the MT8695D Quad Core CPU and only 1 GB of RAM. So if the storage space is full, it can slow down the device as the RAM and CPU would need more time to process the data and handle simultaneous requests at once.

Large app cache

Every app on your Fire Stick stores some data in its cache, which is a temporary storage area that helps the app run faster and smoother in the future. However, over time, the cache can become too large and take up too much space, which can slow down your device. In most cases, the cache generated by the application may not be useful as it would not contribute to your usual usage. Thus, it is necessary to check the applications for extensive app cache and clear the cache from time to time.

Network problems

Fire Stick also relies on a stable and fast internet connection to stream videos and access online services. Whether you are using a wired or wireless connection, it requires bandwidth based on the service you are using as well as the content you’re streaming. If your network is slow or unstable, it can affect the speed and quality of your streaming experience. While there is little you can do except increase the bandwidth of your connection to fix this, you can try out some nominal fixes such as reducing the distance between the router and the Fire Stick or reducing the number of devices connected to the router to reduce the strain on your bandwidth.

Overheating of the Fire Stick

Your Fire Stick can get quite hot when it is in use, especially if it is placed in a tight or enclosed space with poor ventilation. This happens because the processor and other internal hardware of the Fire Stick generate heat as they function. It can cause thermal throttling, which means that the device will reduce its performance and speed to prevent overheating and damage. Generally, each CPU is designed with a thermal throttling logic which slows down the performance of the unit automatically under high temperature to avoid damage to the CPU. Because of that, you may notice the Fire Stick performing well after a reboot, but slowing down after an hour or so because of increased temperature.

Problems with the power supply

Fire Stick also needs a proper power supply to run smoothly and efficiently. To ensure that, Fire Stick is shipped with a dedicated power adapter and a power cable which must be used to power the device. If a low-quality or incompatible power adapter is used,  it can cause power fluctuations, adversely affecting the performance and speed of your device. It can also occur if the power outlet or extender you are using does not offer a uniform power supply. In worst-case scenarios, it can cause permanent damage to the device, which may not be covered by warranty if an incompatible power adapter was used.

Hardware problems

There can be various hardware issues inside the Fire Stick, such as faulty components, loose connections, or physical damage that can cause this problem. These issues can impair the functionality and mainly affect the performance speed of your device. Unfortunately, if your Fire Stick has hardware issues, there isn’t much that can be done since these devices aren’t designed to be repaired. However, you can claim a free replacement from Amazon if your device is under warranty period and it is not affected by any external factor.

Background apps and services

Fire Stick usually executes multiple apps and services in the background, which consume your device’s resources, such as memory and CPU. While some of these apps and services are essential for the operation of your device, others are unnecessary or redundant. If there are multiple redundant services running in the background, it will definitely hamper the performance of the Fire Stick and increase the loading times for the app or service you are using at the moment.

Outdated Fire Stick firmware

Firmware is basically a software component that controls how your device works and interacts with other devices and services. It is important to keep your firmware up to date to ensure that your device runs smoothly and securely. An outdated firmware can cause compatibility issues, security vulnerabilities, bugs, glitches, and performance problems. In most cases, outdated firmware causes problems with app compatibility and increases the installation and opening time for almost all 3rd party apps.

VPN service

VPN is a tool that allows you to change your IP address and encrypt your internet traffic to make it appear as if you are creating the request from a different region. This can help you access geo-restricted content, protect your privacy, and also enhance your security. However, using a VPN service can affect your bandwidth and in turn, the speed and quality of your streaming experience. This is because a VPN service can add distance and additional encryption to your connection, which can slow it down and reduce its bandwidth.

Q. Does restarting the device clear the cache?

A. Restarting your Fire Stick does not automatically clear the cache. However, it may indirectly help with cache management in some cases. Restarting your Fire Stick can clear temporary caches associated with the currently running apps. When you restart the device, it closes all the running apps, and as a result, any temporary data stored in the cache by those apps is usually cleared. Restarting a Fire Stick may also clear some system-level cache. The Fire Stick itself may perform some housekeeping tasks during startup that could include clearing the system-level cache. However, this is typically less effective at clearing significant amounts of cached data.

Q. Is it okay to reset the Fire Stick frequently?

A. While it may not damage the device or the firmware in any way, resetting your Fire Stick frequently is generally not necessary and can be an inconvenient process. While occasional resets can help resolve issues, doing it too often may lead to unnecessary data loss.
