Until the beginning of the last decade, it was normal for phones to have removable batteries. However, as the iPhone, with its non-removable battery, became more and more popular, more and more manufacturers followed the example of Apple.
Eventually, even laptop manufacturers stopped producing removable battery devices. But why is that? And is this good for us consumers? Let’s investigate these questions below!
Lighter and thinner designs explain why smartphones no longer have removable batteries
Despite all the developments in battery technology, batteries are still dangerous. This is due to the fact that it stores energy between the cathodic and anodic electrodes, separated by a thin electrolyte, and in practice, if these electrodes somehow come into direct contact, they catch fire.
For this reason, a removable battery needs a hard plastic case to prevent accidental damage, especially when not connected to the phone.
The problem is that this type of case significantly increases the volume and weight of the smartphone, which is contrary to the wishes of consumers, who are always looking for a slimmer and lighter design. Therefore, one of the solutions that the engineers developed was the installation of a permanent battery.
In other words, the main reason why smartphone manufacturers have started using removable batteries or built-in batteries is that they can make the design of smartphones thinner and sleeker.
New technologies also have their share to contribute
The introduction of modern lithium-ion and lithium-polymer batteries has also allowed smartphones to last longer on a single charge. In this way, despite the increased battery consumption due to the stronger chips and better screens, the simultaneous development of the material and the battery capacity allowed the smartphones to last all day.
Thus, this increased capacity means that users no longer need a spare battery to replace it in the middle of the day. In addition, advances in charging technology mean that batteries can now go from empty to full in less than an hour.
In other words, manufacturers believe that there is no longer any reason to remove batteries from smartphones. It is also worth mentioning that smartphones contain a lot of personal data, allowing malicious people to steal not only your device, but even your financial information.
This is the official reason why many smartphone manufacturers now allow passive tracking of your device, even if you turn off your phone. However, removing the smartphone’s battery eliminates the power source, effectively blocking its ability to track.
Therefore, securing the sealed battery inside a device makes it almost impossible to remove it, so your phone can be tracked even if the device is turned off.
Disadvantages of smartphones without removable batteries
Despite all the advantages that fixed batteries bring us, we still lose some functionality and features along with them. For example, permanent batteries make it difficult for third-party repair shops to repair faulty smartphones, especially when the manufacturer uses adhesives to permanently stick the battery to the internal structure of the phone.
If smartphone manufacturers don’t develop ways to make it easier to remove batteries without the need for heat to melt the adhesive or tweezers to remove them, a permanent battery will continue to be a challenge for repairs.
Despite all the technological advances, there is still the risk of your smartphone’s battery swelling, but since most phones have a permanent battery, you now need to take your device to an authorized service center to have it replaced.
Also, when a permanent battery is overcharged, it may damage other parts of the device. In fact, a swollen battery can damage the screws and glue that hold it in place, and it can remove any protection against the intrusion of external agents in the phone.
Although some are publicly complaining about the lack of removable batteries, the truth is that most consumers are happy with the current arrangement.
In fact, we should keep in mind that smartphone manufacturers do not add or remove features without in-depth analysis; in fact, these changes go through months (sometimes years) of study and consultation.
