Team Tekno World ke free mobile repairing course mein aapka swagat hai! Main hoon Rakesh Chauhan, aur yeh humara Lesson 17 – Battery Drain Solution: Phone Ki Battery Jaldi Khatam Kyon Hoti Hai? hai.
Pichle lesson mein humne “Charging” (Battery bharna) seekha tha. Aaj hum seekhenge ki bhari hui battery “Khali” (Drain) kyun ho jaati hai?
Battery Drain Solution: Phone Ki Battery Jaldi Khatam Kyon Hoti Hai?
Grahak ki shikayat: “Bhaiya, subah 100% kiya tha, jeb mein rakhe-rakhe dopehar tak 20% ho gaya.”
Naye technicians turant Battery badal dete hain. Lekin 50% cases mein nayi battery lagane ke baad bhi problem wahi rehti hai.
Kyon? Kyunki phone mein “Leakage” hai. Phone band hone par bhi current “pee” raha hai. Aaj hum isi chor ko pakadna seekhenge.
Step 1: Software & Settings (Bina Khole)
Phone kholne se pehle, 2 minute ye check karein:
- Apps:
Settings > Batterymein dekhein. Kya Facebook/Instagram background mein chal rahe hain? Unhein ‘Restrict’ karein. - Network: Kya phone aisi jagah rehta hai jahan Network kamzor hai? Kamzor network dhoondhne mein phone double battery khata hai.
- Update: Kya naya update aaya hai? Kabhi-kabhi update mein bug hota hai.
Step 2: Battery Health Check (Physical)
- Visual: Battery ko nikaal kar dekhein. Kya wo Phooli (Swollen) hui hai? Agar haan, toh wo kharab hai.
- Voltage: Multimeter se check karein. Agar 3.7V hai par load padte hi voltage gir jaata hai, toh battery ke cells weak hain. Nayi battery lagakar dekhein.
Step 3: Hardware Leakage Check (Half Shorting)
Agar nayi battery bhi nahi tik rahi, toh motherboard mein Half Shorting hai.
Test 1: Phone OFF Condition (DC Machine)
- Phone ko DC Power Supply (Lesson 13) se connect karein.
- Phone ko ON NAHI karna hai. Bas cable lagaye.
- Reading Dekhe:
- 0.000 A: ✅ OK. (Band phone koi current nahi le raha).
- 0.010 A – 0.080 A: ⚠️ Leakage. (VPH line mein koi component leak hai).
- Result: Agar yahan reading aa rahi hai, toh phone rakhe-rakhe discharge hoga.
Step 4: “Deep Sleep Mode” Test (Pro Tip)
Yeh sabse Professional Test hai. Kabhi-kabhi phone OFF hone par leakage nahi dikhata, lekin ON hone par sota (Sleep) nahi hai.
Test 2: Phone ON Condition
- Phone ko DC Machine se ON kare.
- Phone ko menu mein chhod dein aur Power Button dabakar Screen OFF (Lock) kar de.
- 1-2 minute intezaar kare.
- Reading Dekhein:
- Normal: Reading 0.000 se 0.005 ke beech aani chahiye. (Matlab phone “Deep Sleep” mein chala gaya hai).
- Faulty: Agar reading 0.150 – 0.250 par hi upar-neeche ho rahi hai (Zero nahi ho rahi).
- Result: Phone ka CPU “so” nahi raha hai. Koi IC (Audio, Network, Wi-Fi) usey jaga kar rakh rahi hai aur battery kha rahi hai.
Step 5: Battery Drain Solution (Repair Kaise Kare?)
- Garam Hissa: Phone ko thodi der DC machine par chhod dein (Leakage condition mein). Phir haath se touch kare. Jo hissa Garam (Warm) lage, wahan fault hai.
- Rosin Smoke: Garam hisse par Rosin ka dhuaan kare. Jo capacitor pehle pighlega, wahi leakage kar raha hai.
- Secondary Line Check: Agar phone Deep Sleep mein nahi ja raha, toh aksar Charging IC ya Power IC ke paas leakage hoti hai.
Battery Drain Solution – Summary Checklist
- Settings aur Battery condition check kare.
- DC Machine (OFF Mode): Kya bina ON kiye current le raha hai? (Leakage).
- DC Machine (Sleep Mode): Kya Screen band hone ke baad current 0.000 ho raha hai? (Deep Sleep).
- Jahan current high ho, wahan Heat check karein aur Rosin use kare.
💡 Aaj Ka Aapka Task – Lesson 17 (Comments & Forum)
- Practical: Apne chalu phone ko DC machine par lagayein. Screen Lock karein aur dekhein ki kitne second baad reading 0.000 hoti hai? (Isse Deep Sleep kehte hain).
- Comment: Kya aapne kabhi “Phooli hui” battery dekhi hai? Yes/No likhe.
- Forum: Agar leakage pakad mein nahi aa rahi, toh DC reading ki video Forum (forum.teamtw.in) par share kare.
Agla Lesson: Battery drain ka bada bhai hai “Overheating”. Jab phone aag ki tarah tapne lage toh kya karein? Agla lesson hai: “Lesson 18: Overheating Problem (Phone garam kyon hota hai?)”।
