Cell phone designs have evolved a lot since the time of the Motorola flip phones, the first Palms, and the original Nokia 3310 series. The early cell phones had a lot of replaceable parts or could be opened by sliding the cover off the phone. Nowadays, most cell phones are integrated designs where the case is integrated with the rest of the phone.
Today’s cell phones either have integrated bodies which cannot be easily opened like the iPhone, or these might have cover door combos, where the battery is part of the back door or cover. The consideration for this design is how the battery fits the electronics and ensures that it does not touch any part which might turn hot during operation.
How to choose the right one?
When you need to replace your battery, you should consider whether the phone has a cover door combo or separate battery and cover. In some cases, you can pick to have a cover door combo to replace the separate battery unit.
One advantage of the cover door combo is that there is no more extra part to consider. This helps to protect the battery because the cover door is integrated with the battery. In case an accident happens, and the battery comes loose, the back cover also provides additional protection. Sometimes, however, buying a new cover door, whether alone or part of the combo can lead to loose covers because it does not have a tight fit.
If, however, your cell phone cover door is still intact and closes tight, it would be better to buy a separate battery instead.
Features and Benefits
As an external feature, the main disadvantage of buying a cover door combo is that it might not match the cell phone color exactly. Also, any purchase of the cover door might not have a tight fit, especially with a new battery.
If you were to buy an extended cell phone battery [link to”Cell Phone Battery Types”], it would be better to have a cover door combo instead. Otherwise, you would be forced to buy a separate cover which might not fit the larger battery. Extended cell phone batteries usually come as a cover door combo because of this problem. The Samsung M510 Extended Battery and Pink Door is an example of an extended battery and cover door combo.
How to keep your battery door from breaking?
It is a common problem with cell phones which have back covers. These covers usually fly open when you drop the cell phone. Of course, this does not happen when you have a cell phone without a back cover or one that was designed to be always tightly closed. Being wary not to drop the phone is a good start to taking good care of your cell phone.
For battery doors, it is important to keep it always closed. Repeated opening and closing will make the cover loose over time. This means that the cover can come loose without much pressure. Another safety precaution is not to keep your cell phone in your back pants pocket. This flexes the cell phone unnecessarily. It can even break or damage the glass screen. The most important consideration is to keep the phone from overheating. This usually happens when you have several apps running at the same time, or when you are recharging the phone.
The battery cover is meant to protect the cell phone from the elements. Keeping it always tightly closed is an important thing to remember.
