Team Tekno World ke free mobile repairing course mein aapka swagat hai! Main hoon Rakesh Chauhan, aur yeh humara Lesson 16 – Charging Problem Fix: Slow, Fake & Temperature Error Solution hai.
Pichle lesson mein humne “Dead Phone” diagnose karna seekha. Aaj hum us samasya par baat karenge jo market mein sabse zyada aati hai: “Charging Problem”।
Lekin dosto, Charging problem sirf “Charge nahi ho raha” tak seemit nahi hai. Grahak 3 tarah ki shikayat lekar aayega:
Charging Problem Fix: Slow, Fake & Temperature Error Solution
- Dead Charging: Charger lagane par kuch nahi ho raha.
- Slow / Fake Charging: Raat bhar lagaya par sirf 10% bada, ya charging show kar raha hai par battery nahi badh rahi.
- Charging Error: “Temperature too high/low” ka error aa raha hai.
Aaj hum in teeno ko Professional Tareeke se diagnose karna seekhenge.
Step 1: USB Ampere Tester (Jaasoos) Ka Use
Phone kholne se pehle, apne 6-Port USB Charger (Lesson 7) par phone lagayein aur Reading (Ampere) dekhein. Yeh sabse bada raaz hai.
| Reading (Ampere) | Result (Natija) | Solution |
| 0.00 A | Connection nahi hai. | Cable badlein, Port saaf karein, ya Jack kharab hai. |
| 0.10 A – 0.40 A | Slow/ Fake Charging. | Cable kharab hai ya Charging Port mein carbon hai. Phone charge dikha raha hai par ampere kam le raha hai. Charging IC ya Battery fault. |
| 0.60 A (Dikha kar 0.00 ho jana) | Loose Connection. | Charging Port andar se loose hai (Dry Solder). |
| 0.60 A – 1.0 A | Normal Charging. | Phone charge dikha raha hai par ampere kam le raha hai. Charging IC ya Battery fault. Charging bilkul sahi hai. |
| 1.2 A – 2.0 A+ | OK (Fast Charging). | Charging bilkul sahi hai. |
Step 2: Port Ki Safai (Basic Repair)
Agar reading 0.00A ya 0.40A (Slow) hai, toh turant jack na badlein.
- Reason: 80% cases mein jeans ki rui (lint) aur dhool port mein jama hoti hai.
- Action: Patli chimti (tweezer) se kachra nikaalein aur IPA se brush karein. Phir check karein.
Step 3: Hot Testing (VBUS Tracing) – [Hardware Check]
Agar safai ke baad bhi charge nahi ho raha, toh Phone Kholein (Lesson 14) aur Multimeter ko DC 20V par rakhein. Charger laga rehne dein.
Check 1: Sub-Board VBUS (Neeche)
- Sub-board par VBUS Point par 5V check karein.
- Result: Agar 5V nahi aaya = Charging Jack Kharab hai. (Badal dein).
Check 2: Main Board VBUS (Upar) – [Zaroori Step]
- Aksar technicians neeche check karte hain, par upar bhool jaate hain.
- Flex Cable (Patta) kharab hone se neeche toh 5V hota hai, par motherboard tak nahi pahunchta.
- Action: Main Board ke connector par 5V check karein.
- Result: Agar neeche 5V hai par upar 0V hai = Charging Patta (Flex) kharab hai. Usey badlein.
Step 4: Battery Connector & BSI (Charging Error)
Agar grahak kehta hai “Temperature too high” ya “Voltage Error”:
- Yeh samasya Jack ki nahi hai. Yeh samasya Battery ya BSI Line ki hai.
- Check: Battery Connector par BSI Point (Beech wala pin) check karein. Kya uspe reading (GR Value) aa rahi hai?
- Solution: Battery badal kar dekhein. Agar fir bhi same hai, toh motherboard par Thermal Resistor kharab hai (Yeh hum IC level mein seekhenge).
Summary Checklist
Charging Problem Fix: Slow, Fake & Temperature Error
- USB Tester Reading dekhein (0.6A se upar hona chahiye).
- Port Cleaning karein (Lint nikaalein).
- VBUS (5V) neeche aur upar (Main board) dono jagah check karein.
- Battery badal kar dekhein (Fake charging/Error ke liye).
💡 Aaj Ka Aapka Task – Lesson 16 (Comments & Forum)
- Practical: Apne ghar ke charger par dhyan dein. Kya adapter garam hota hai jab phone charge hota hai? (Agar haan, toh wo sahi ampere le raha hai).
- Comment (नीचे): Kya aapne kabhi “Fake Charging” (Charge dikhana par badhna nahi) face kiya hai? “Yes/No” likhein.
- Forum: Agar “Temperature Error” aa raha hai, toh phone ka model number humare Forum (forum.teamtw.in) par batayein, hum aapko Thermal Resistor ki location denge.
Agla Lesson: Charging theek hai, lekin battery paani ki tarah beh rahi hai (Drain)? Agla lesson hai: “Lesson 17: Battery Drain Fast (Phone jaldi discharge kyon hota hai?)”।
