If you’re having issues with your non-removable battery charging or not holding a charge, here are some helpful tips. If your device has a removable battery,
- Check the charging port for water damage or corrosion.
- Check the charging port for bent or broken pins and lint.
If the device won’t power on, press and hold thePower button
for 5-10 seconds.If the device powers on, but doesn’t hold a charge, power cycle the device then charge fully and re-test.
- Ensure a manufacturer-approved wall plug and USB charging cable are used to avoid extended charging times or other charging issues.
- While connected to the wall charger, attempt to power on the device.If device doesn’t power on, wait 1-2 minutes and re-test.
- Verify the device and/or charger display the appropriate charging/LED indicator.If the battery is extremely low, the display may remain blank for up to 5 minutes before a low battery image appears. It may take 15 minutes to 2 hours before the device can be powered up.
- Attempt to power on the device using an alternate manufacturer-approved charger, if available.
- If the device still won’t power on, trickle charge using a manufacturer-approved USB cable plugged into a computer. Many times devices that are completely dead recover after 45 minutes to 2 hours using this trickle-charge method. After the device recovers, finish charging by plugging into a wall outlet.
While connected to the wall charger, press and hold thePower
for 1-2 full minutes.This process may help power on the device when only pressing the Power button is unsuccessful.

Follow these Steps One after Another:
- Change the charger and check. Voltage must be 5 to 7 Volts.
- Clean, Resold or Change the Charger Connector.
- If the problem is not solved then change the Battery and Check. Non Removable Battery are Just Glued at the Bottom. They can be Removed Easily but Little Carefully.
- Check Voltage of the Battery Connector using a Multimeter. Voltage must be 1.5 to 3.7 DC Volts.
- If there is no voltage in the connector then check track of the charging section. Refer to the diagram of the particular model of the mobile phone. Books with track diagrams are easily available in the market. The same can also be searched on the internet.
- If the problem still not fixed then check Fuse, Coil and Regulator – one by one. Change if required.
- If the problem is still not solved then Heat or Change the Charging IC.
- Lastly Heat, Reball or Change the Power IC.
- If the phone shows “NOT CHARGING” then change the Battery and check. If the problem is not solved then remove the charging regulator (no need to change it).
- If the problem is still not solved then change the R22.
- If the problem is not fixed then remove the two SMD capacitor above the Battery Connector (No need to change).
- If the problem still persists then change the Charging IC.
- If the Phone Shows “FALSE CHARGING” then use a 3.6 Volt Zener Diode and do Direct Charging.
