Yes, your phone almost certainly uses a lithium-ion (Li-ion) battery.
Li-ion batteries are the dominant power source for modern smartphones due to their advantageous characteristics:
- High Energy Density: They pack a lot of power into a small and lightweight package, essential for slim and portable phones.
- Low Self-Discharge: Li-ion batteries hold their charge well when not in use, meaning your phone won't be dead after sitting on a shelf for a short period.
- Rechargeability: They can be charged and discharged hundreds of times, providing a long lifespan for your device.
While earlier mobile phones used other battery chemistries like Nickel-Cadmium (NiCd) or Nickel-Metal Hydride (NiMH), those have largely been replaced by Li-ion due to their superior performance and environmental benefits. Though Lithium Polymer (LiPo) batteries also exist, and are another type of Lithium-ion battery.
In summary, it's highly probable that your phone utilizes a lithium-ion battery to power its operations.
