How to Fix Common Charging and Temperature Issues in Mobile Phones: Nokia TA 1410 and Itel 2163

 

Mobile phone repair often involves addressing frustrating charging or temperature-related errors. In this guide, we’ll walk through solutions for two common issues:

1. Nokia TA 1410: Not Charging

2. Itel 2163: “Temperature Too High, Power Off Soon”

Both problems can be resolved using a 10k resistor placed between the BSI/BTI and Ground of the battery terminals on the phone. This simple yet effective solution offers a workaround when the standard battery is unavailable.

Case 1: Nokia TA 1410 - Not Charging

Issue:

The Nokia TA 1410 might fail to charge due to improper recognition of the battery. The root cause is often a mismatch or a defective BSI (Battery Status Indicator) signal. The ideal fix is to use the standard battery, but these can be hard to find.

Solution:

1. Identify the BSI/BTI terminal on the phone's battery connector.

2. Solder a 10k resistor between the BSI/BTI terminal and Ground.

3. Reconnect the battery and test the charging functionality.

This fix creates a simulated resistance, mimicking the standard battery behavior and allowing the phone to recognize the battery properly.

Case 2: Itel 2163 - Temperature Too High

Issue:

The Itel 2163 may display a "Battery Over Temperature" error due to incorrect temperature readings. Like with the Nokia TA 1410, the problem stems from the unavailability of a proper standard battery.

Solution:

1. Locate the BSI terminal on the phone's battery connector.

2. Attach a 10k resistor between the BSI terminal and Ground.

3. Test the device to ensure the temperature error is resolved.

Why Does This Work?

The BSI terminal communicates vital battery data, such as temperature and charge levels, to the phone. When a non-standard battery or an improper connection causes these signals to fail, the phone may misbehave (e.g., showing high temperature or refusing to charge). The 10k resistor provides a consistent resistance value, stabilizing the signal and bypassing the problem.

When Should You Use This Fix?

1. When the original battery is unavailable or incompatible.

2. When immediate repair is required, and sourcing the right battery isn’t feasible.

3. For testing purposes during diagnostics.

Important Notes

Always ensure proper soldering techniques to avoid damage to the phone’s components.

If available, replacing the battery with the correct standard one is always the preferred solution.

This fix is an expert-level technique and should only be attempted by experienced repair technicians.

With these straightforward steps, you can bring devices like the Nokia TA 1410 and Itel 2163 back to life. This method highlights the ingenuity and resourcefulness
