Battery problem in Samsung's phone with extended screen

Samsung is developing a new phone with an expanding screen feature. The aspect ratio of the screen can vary from 16:9 to 21:9. However, the price of this flexibility is that the space available for the battery inside the phone is limited.

Samsung's expanding screen gets longer according to its function

The information was shared by Ice Universe, known for its reliable leaks. According to him, some users prefer a wider screen and some prefer a higher screen. This design aims to respond to the wishes of both groups.

The screen can change between 16:9 and 21:9. Thus, the user will be able to adjust the screen ratio according to the work he is doing. Moreover, it will be possible to switch between two different rates with a single device.

Ice Universe says that if Samsung can pull this off, the solution could be very attractive. But the condition at the beginning of this sentence is important. Because whether the idea works depends on how the mechanism will fit into the device.

The main problem is the battery

The person who shared the leak stated that the main obstacle is battery capacity. The mechanism that pushes the screen out will take up a lot of space inside the device. Therefore, the space left for the battery will decrease.

Internal volume is limited in phones. Therefore, every millimeter allocated to the mechanism goes to the battery. Ice Universe draws attention to exactly this balance.

Could be Galaxy Z Roll

According to SamMobile, Samsung has been showing roll display concepts for years, but these came from display manufacturer Samsung Display. This time, it is said that Samsung's mobile department is working on the device, meaning that the first commercial roll-screen phone may be on the way.

The 16:9 ratio is suitable for standard videos, while 21:9 is suitable for movies, long documents and web pages. The phone will be more compact in 16:9 format. According to previous rumors, Samsung aims to release this phone in the first half of 2028; The company also registered the name "Galaxy Z Roll".

Questions awaiting answers

The questions Ice Universe leaves open are: How much capacity will Samsung be able to fit inside? Will the battery life be sufficient with the screen fully on?

The answers to these questions will determine whether the phone will be useful in daily use. On the other hand, Samsung has not yet made an official statement about the expanding screen. So there is only one leak for now.

Samsung has not yet shared an official launch date or price. The device is currently in the leak phase. If Samsung turns the expanding screen idea into a product, its solution to battery capacity will be the detail to watch most.
