Many iPhones with “battery jack” are being sold widely on the market, users need to be very alert

Although not a new form, but the battery-powered iPhone has become a nightmare not only for those who have unfortunately bought it, but it also threatens used iPhone stores.

Users need to be very careful with older iPhone models, but the battery condition is almost perfect (Artwork)

Specifically, battery-powered iPhones are old devices with batteries that have been bottled through the previous owner’s use. However, with a few tricks, many merchants have turned this parameter back to a “nearly new” state, ie, about 90-100%, in order to deceive users.

Going back a bit in 2018, when iOS 11.3 was released, Apple provided users with a “battery health” feature to know if this component has been damaged or not. If the battery condition is below 80%, the iPhone will automatically reduce the device’s performance to optimize usage time and ask the user to replace the battery with a new one. Used iPhone buyers in Vietnam also often rely on this parameter to assess the device’s condition and product pricing.

In 2018, Apple added the iPhone battery health monitoring feature through the iOS 11.3 update

Knowing the user’s psychology, the dealers will fake this parameter in many forms, it may be to replace the “batch” battery to return the battery as new or more sophisticated than “battery jack”. “. Through references from many individuals selling used iPhones, we know that this is a potentially risky process.

To conduct “pinning”, we need a specialized device capable of overwriting information directly on the component. This process requires removing the device, removing the battery to make the connection. During the operation, the battery is most likely to be deformed, damaged socket, causing many consequences later.

The operation to activate the battery is performed extremely sophisticatedly (Artwork)

Thanks to such direct interference with the component, the user will not have any effective method to check if the device’s battery has been tampered with. Including resetting the device and plugging in the component testing software. More sophisticated, many subjects only “click” for battery status to about 90% to avoid causing suspicion. However, in many cases, the device will be “returned” to the old battery status after 5-10 days of use.

The consequence of this action is that although the display parameters are “perfect”, the actual usage time of the user is very poor, sometimes the device heats up abnormally, even lags due to components. has been interfered with.

Users need to be very careful when choosing a shopping address

According to Mr. Bach, a long-time iPhone trader in Ho Chi Minh City, this “battery jack” trick has existed for a long time, but only appears on older iPhone models that are popular with users like iPhone X, iPhone XS. Max. Recently, new iPhone lines, such as iPhone 11, 11 Pro and 11 Pro Max have also begun to appear “battery size”.
