Non-removable batteries have become increasingly common in smartphones. This is because smartphone manufacturers have found it more convenient for users to have a battery that is not removable.
One of the main reasons for this is that if they make the battery removable, then they will have to add extra protection for the battery which can make the phone bulky and heavy.
In contrast, non-removable batteries can be designed to be adjustable with high mAh battery, which allows for a longer battery life.
Another reason why manufacturers prefer non-removable batteries is because they don't want to give users the option of purchasing a replacement battery if the original battery gets damaged.
This is because if a user can easily replace the battery, then they may not feel the need to purchase a new smartphone even if the phone is old. This can negatively impact the smartphone industry as people will not be buying new phones as frequently as manufacturers would like.
However, It is important to note that smartphone batteries do degrade over time, regardless of whether they are removable or not. After 2 to 3 years of use, it's not uncommon for a battery to be damaged and in need of replacement. With non-removable batteries, users are left with no choice but to buy a new phone instead of simply replacing the battery.
Non-removable batteries have become the norm in smartphones due to the convenience for manufacturers and their marketing strategies.
While it may be less convenient for users in the long run, it's important to remember that all smartphone batteries will eventually degrade and need to be replaced.
