হঠাৎ বন্ধ হয়ে গিয়েছে।⚡️⚡️⚡️💥
কাষ্টমারের অনেক গুরুত্বপূর্ণ জিনিস রয়েছে ফোনে । অনেক জায়গায় দেখিয়েছে । মাদারবোর্ড পাল্টাতে হবে বলেছে সবাই। কাষ্টমারের বিপদের কথা ভেবে কাজটা নিলাম🐞 🎀 🎀 🐞

পাওয়ার সাপ্লাইতে লাগিয়ে দেখলাম রিডিং 0.09amp, আটোমেটিক Qualcom 9008 port পায়। Isp connect দিয়ে দেখলাম error দেখায়। ফোনে সামান্য সর্ট দেখাচ্ছে ও CPU'র বল সাইড থেকে বের হয়ে আছে।
CPU & EMMC রিবল করলাম । আলহামদুলিল্লাহ প্রথম চান্সেই কাজ হয়ে গেলো । ✅✅✅💯😲🍩 𝔸ĻⒽ卂м𝐝ǗĹ𝕚ⓁĻคн 😂💘

কাষ্টোমারের খুশি দেখে নিজের কাছেও অনেক ভালো লাগলো। সময়ের অভাবে পোষ্ট করা হয় না । অনেকেই ভুল জায়গায় ফোন গুলো ঘাঁটিয়ে আনে।তখন চাইলেও সহজ কাজগুলো আর করা যায় না।

Basic Knowledge For those whose are anxious about the error " temperature too low or high "

Kinds of mobile phone battery.

NiCd
NiMH
Li-Ion
Li-Polymer

Li-Ion or Li-Polymer (we only discuss about it )

These Batteries are used in latest phones and electronics machines and also it have long life time and efficiency.When we think about mobile phone faults, some faults are comes with battery. Then we want to identify what are the faults comes with battery and how can we solve it. fistly we want to know about battery pin out and types of pin out

1. GND : Ground or negative Terminal.
2. BAT : Battery Positive Terminal.
3. BSI : Battery Site Indicator.
4. BTemp : Battery Temperature.

1. GND or Negative Terminal:

Ground or negative terminal is a reference point for measuring other voltage or returning point for electric current and also it is same to negative battery terminal.

2. BAT +

VBat or Positive terminal is also known as Battery Positive terminal , BAT+ or +.

3. BSI

BSI is also known as Battery status Indicator or Battery System Indicator.There are some mobile phones, which has shorter BSI pin. It is because when the battery is being removed when the phone is turned on, the BSI circuit interrupts first, which tells the processor to shut down all communication to prevent damage.

The battery block contains BSI resistor for battery identification. The BSI fixed resistor value indicates the chemistry and default capacity of a battery. Temperature and capacity information is needed for charge control (charging current and the voltage).
It is connected to resistor to GND. The phone measures the resistance of the BSI - GND connectors, and it can determine which kind of battery is in the phone.
Examples: Nokia NiMH batteries:
BMC-2 640mAH 3.3 kOhm
BMC-3 900mAH 5.6 kOhm

Nokia Li-Ion batteries:
LB-2 650 mAH 68 kOhm
BLC-2 900 mAH 75 kOhm

4. Battery Temperature

B Temp is also known as Battery Temperature or NTC. The battery block contains NTC (and usually BSI) resistors for temperature measurement. Temperature and capacity information is needed for charge control. These resistors are connected to BSI and BTEMP pins of the battery connector.

The phone stops the charging, if the battery is starting to overheating.
In case of NTC thermistor, if the temperature increasing, the resistance decreasing. The temperature of the battery make the resistance beetween the GND and the BTemp change.

There are batteries which don't have BTemp connector. In this case, the phone has the temperature meter which is in the mobile phone, close to the battery.
