This glossary explains common mobile terms in simple words.
Display
AMOLED / OLED: Deeper blacks, better contrast, usually more vibrant.

HDR: Improves contrast and highlights for supported content.
Performance & Storage
Chipset/SoC: Main “brain” of the phone (CPU + GPU).
RAM: Helps with multitasking. More RAM usually = smoother switching.
UFS vs eMMC: UFS is faster storage; apps and file transfers feel quicker.

Camera
OIS: Optical stabilization; improves low light and reduces shaky video.
EIS: Software stabilization mainly for video.
Aperture (f/): Lower number usually captures more light.
MP (Megapixel): Not the only quality measure—sensor and processing matter.
Battery & Charging
mAh: Battery capacity; higher usually lasts longer (depends on usage).
Fast Charging (W): Higher watt can charge faster (depends on tech/heat).
Network & SIM
5G / 4G LTE: Network generations; depends on coverage and bands.
Dual SIM: Two SIM cards; some phones use one SIM + one SD slot.
