　　lithium polymer battery protection technology makes new iPhone thinner and larger

　　Apple’s battery statement during the iPhone 11 launch event surprised many fans. Yes, all three iPhone 11 series phones this year have undergone considerable upgrades in battery life, and their use time has been greatly improved.

　　The new phones are more efficient than ever thanks to the new A13 chip, but that's not the only reason. All iPhone 11 models do not have a 3D Touch touch layer, and the body is slightly larger than the iPhone XS and XR. These factors have led Apple to slightly increase the battery size of the three mobile phones. Compared with the XS Max, the battery life of the iPhone 11 Pro Max has increased by as much as five hours.

　　Apple said that in 2020, Apple will launch five new mobile phones, four of which belong to the iPhone12 series. They are: iPhone12, iPhone12Plus, iPhone12Pro and iPhone12ProMax. All four iPhone12 models will support 5G networks and one is iPhoneSE2.

　　From this point of view, as the iPhone supports 5G networks next year, it is foreseeable that power consumption will further increase. It is another challenge for iPhone to keep the body from becoming thicker while supporting 5G and increasing battery capacity.

　　However, a few days ago, Korean media quoted industry insiders as saying that iPhone may have found a solution to these problems. The iPhone series of mobile phones may use new batteries provided by suppliers in 2020, which will make the battery life of the new iPhone even longer. One floor; this lithium polymer battery improves the circuit design used in previous iPhones by merging the MOSFET (metal semi-field effect transistor) with the PCB board and removing the component casing. By further reducing the length and thickness, the overall battery protection module has been reduced in size by nearly 50%, thus freeing up more space to further increase battery capacity.

　　In addition, this specially designed battery protection module can also prevent battery overcharging and over-discharging. They are essential battery components to improve battery life. It is said that the battery protection module will be provided by South Korea ITMSemiconductor.

　　If this technology is really adopted, next year's iPhone will not only ensure the battery life of 5G models, but also ensure the thickness and weight of the fuselage, which is another improvement in battery protection technology.

　　It is worth mentioning that according to Korean media reports, the Samsung Galaxy S11 series to be launched next year may also use the same technology.
