If you do not require wireless functionality, consider investing in a wired mechanical keyboard. Consider purchasing a USB On-the-Go (OTG) cable if you require it for a mobile device (make sure your device is compatible with OTG cables, although most Androids are).
Here are the top 4 reason why shouldn’t consider buying a bluethooth keyboard.

1. Bluetooth Has Issues With Pairing
This is Bluetooth’s primary difficulty, as seen by the plethora of complaints regarding compatibility concerns in user evaluations of Bluetooth keyboards. For instance, there are numerous complications that can arise when connecting Bluetooth to Ubuntu. It used to be even worse. At one point, Ubuntu was unable to communicate with Bluetooth 4.0 devices.
Windows 7 was incompatible with Bluetooth 4.0, which Microsoft addressed with the release of Windows 8.1. Additionally, Android versions prior to 4.3 Jelly Bean will not support the Bluetooth Low Energy extension. While some Bluetooth pairing issues can be resolved, overall compatibility issues can negate the primary benefit of Bluetooth keyboards.
Hopefully, Wi-Fi Direct keyboards will become available in the future. Wi-Fi Direct requires a Wi-Fi Direct-compatible wireless card, which is acceptable given the compatibility of the majority of recent Android devices. The issue is that high-quality Wi-Fi Direct keyboards are few.
2. Standards Become Outdated & Uncertain
In comparison to a wired connection, the Bluetooth wireless protocol evolves swiftly over time, which is wonderful except for the fact that Bluetooth keyboards do not receive security upgrades as they age. As a result, what is deemed secure now may be easily attacked in the future.
For instance, the National Security Agency (NSA) of the United States produced a best-practices guideline for Bluetooth usage, noting that older Bluetooth standards that do not support the Low Energy extension are vulnerable—which includes virtually all Bluetooth 3.x keyboards. Additionally, there is a lengthy list of potential security vulnerabilities and Bluetooth security flaws, including Bluejacking and Bluebugging.
This is a critical issue because many users enter their passwords and usernames using a keyboard. If the text input from that keyboard is transferred to a hostile middleman, you have provided a criminal with your login and password information.
That is why all wireless keyboards must include user-upgradable firmware. A few of these gadgets mix Bluetooth, firmware upgradeability, and mechanical switches.
3. Bluetooth Keyboards Are Not Ideally Suited for Gaming
If you like to game with a keyboard, wired keyboards are your best bet. Bluetooth keyboards are not suitable for gaming, whether you are a casual or competitive gamer. This is primarily due to the substantially longer delay. Latency is a term that refers to the amount of time required for the keyboard to register a keystroke on the screen.
The higher the latency, the longer it will take for the screen to display your keystroke. Bluetooth keyboards, with their increased latency, are better suited for informal office work where lightning-fast reactions are unnecessary. Gaming needs you to react quickly, which dictates whether you win or lose a game.
Although many Bluetooth keyboards are marketed as gaming-oriented, they cannot compete with tethered keyboards in terms of latency. Therefore, avoid using a Bluetooth keyboard while gaming at all costs. Rather than that, disregard the producers’ marketing ploy.
4. Bluetooth Keyboard Batteries Are Not Inexhaustible
Indeed, the battery life of a Bluetooth keyboard may be as little as a few years. All Lithium-ion (Li-ion) batteries degrade over time, and the more discharge-charge cycles a battery undergoes, the faster its battery chemistry degrades. Additionally, while a rarely charged Li-ion battery might survive an extended period of time, the majority are not user-replaceable.
If it does fail, you’re out of luck unless you have soldering abilities. Bluetooth keyboards with removable batteries are available, although they are few and few between. The Logitech K780 is an exception.
Should You Consider Purchasing a Bluetooth Keyboard?
Because there is no perfect Bluetooth keyboard solution, you must either make a compromise or forego purchasing a keyboard. If your laptop keyboard, for example, stops working, you may require a Bluetooth keyboard. If you must get a Bluetooth keyboard, we recommend either going cheap or purchasing the Keychron K4 100-key mechanical keyboard.
The Keychron K4 is reasonably priced and features both USB (Type-C) and Bluetooth connection in a small package. At this pricing point, the Keychron K4 is one of the best portable Bluetooth keyboards available.
Regrettably, its thickness may restrict how you carry it. For those searching for a compact keyboard that can be used with a smartphone or tablet, the Logitech K780 is one of the best options available.
If you do not require wireless functionality, consider investing in a wired mechanical keyboard. Consider purchasing a USB On-the-Go (OTG) cable if you require it for a mobile device (make sure your device is compatible with OTG cables, although most Androids are). Finally, Bluetooth keyboards are not suitable for gaming if you require a gaming keyboard due to their increased input lag.
