Jab Maine phli baar SuperVOOC charger haath me lia , the first thing came in my mind ki ye sala kaam kaise karta hai ! 🤔 I mean is qadar fast koi kaise charge krta hai bina heat hue !! Tb maine thodi si technicalities dekhi or tab smjh me aaya ki Super VOOC Ek Ampere based charger hai. ( Mostly hamre paas jo hote hai wo Voltage based hote h ) Mere paas jo charger hai wo 5V - 4A (20watt) pr operate krta hai. Ab ek mastt baat btata hu jo bhi phone SuperVOOC support karta hai uski battery cells split hoti hai ( padha hai kahi , link nh h lekin ) I mean 4000 mah battery ki cells ko 2000+2000 cells me split kar do or dono ko parallel mode pr jod do ! Ab voltage dono ko same chahiye but current jyada chahiye uske liye unhone Voltage ko 5V rakhke current ko sidha double kr dia . Isse fayda ye hota hai ki aap 2000 mah ki 2 battery ko ek sath charge krte hai. Time reduce ho jata h , yani jitne der me ek voltage based charger 2000mah charge krta h , ampere based charger 4000mah kr deta hai. Agar aap isko Qualcomm ke 18W charger se bhi compare krenge to bhi ye fast hoga. Ab baat karte hai heat kyu nh hota , simply H= I²RT , ab current jyada hai pr resistance or time dono km hai , ( R=V/I ) bs isiliye ye km heat karta.

Bht saare logo ko janna tha ki camera setup phone ke kaise kaam krte hai ! To aaz isi baare me baat karte hai.
1. Single camera - Ye phone ka primary lens hai usual focus range f/1.5 to f/2.4 ( lesser is better ). Phone ka main camera full subject capture krta h. Videos at higher framerate , support for OIS and EIS , slo-mo , hyperlapse , and panoramas ye sb main camera ke feature hai.
Ab jitne bhi lens hote hai sb isi main sensor ke upar depend krte hai. Main jo hmare yha par dual camera setups hote hai unme secondary lens 3 type ke hote hai - Depth sensor , monochrome sensor , and Telephoto lens.
2.a. Main + Depth sensor - Depth sensor basically CMOS type sensor with IR projector hota hai jo IR signals ki help se whole area ka 3D depth data create krta hai. Generally OEMs Duo M sensor use krte hai jo 1- 2.5m ki range pr depth data bnata hai isiliye waise phone ke portrait mode jisme depth sensor use kia gya ho apko subject ko 2.5m ki range me rhne ko kaha jata hai. Basically ye sensor bokeh achieve krne lagaya jata hai or iska koi role nh, portraits perfect nh aate h still Telephoto ke comparison me cheap hone ke karan oem isko use karte h.
2.b Main + Monochrome sensor - Monochrome sensors picture me better details dene ke liye use kia jata hai. Kyuki camera sensors khud colors differenciate nh kr skte unme ek pixel sized color filter use kia jata hai isse har pixel ek specific Red , Green ya Blue Color capture karta hai. Output pixels ko combine krke image bnaya jata hai. Ab problem ye aati hai ki us color array ke karan image quality decrease ho jati h or kyuki har pixel ek individual color capture krta hai isse lens ki sensitivity kam ho jati hai bs isliye monochrome sensor ko combine kiya jata h jo ek b/w full quality image capture krta hai main RGB sensor ke sath or main sensor color capture krke usme fill kr deta hai. Night time or low light me ye bht achhi clarity ki images produce kr skta hai. Still iske sensor costly hai to ye sensor jyada phones me dikhta nh h , mostly Huawei hi isko use krti hai.
Post bht badi ho gyi hai ! So we'll discuss Telephoto & Optical Zoom in next post and Wide Angle & Macro in other post.
