  1. i, I got a problem on my Lenovo K900.

    The battery power strength does not update the status while discharging (in-use).

    Let say you charge to 100% and start using it afterwards. The status remain 100% despite of my usage for several hours until it sounds beep and showed ” 0% – Shutting down “.

    Hope to get your advice.

    Thanks.

    • Hi, that problem usually come from the applications which make the native battery status become problem. You can try to install 3th party battery status bar to detect that the problem really come from your application. Please only install recommended battery status bar from Google Play Store, because some applications may make our phone become problems and act not normal. If you can not find the solutions, you should consider to do hard reset and hopefully the problem of default battery status will be fine.

Please bring your Lenovo K900 to nearest Lenovo service center to ask for further test.

  3. I have one problem with my K900 phone now. I cannot charge my phone while i use it. But i need to shut down my phone if i want to charge my phone. Another problem, after a fully charge, my battery power will decrease to 0% after 4-5 hours when i open my K900 phone. What should i do? Can anyone tell me how to open the case so i can pull out the battery from the phone? I try to open it before but unsuccessful. Please, need your help ASAP…

    • Hi, base on your information, the problem happen because your Lenovo K900 working so hard or there are some applications run in the background without any notice, that is why your Lenovo K900 work to hard and need more power. Therefor the power from Charger is not enough if compare by the output power from the phone. So you need to turn off your phone to charge fully without any process in the phone because powered off. In this case if you can not find that trouble applications, then we strongly suggest you to do hard reset, and after the hard reset process finish, try to charge again, it should charge run normally.

      Another possible causes can be happen at your charger. Your charger adapter may get damage and the output to charge is not enough, but we are worry the problem comes from your Lenovo K900 itself, because you said the battery only lasting for 4 until 5 hours (but we are not sure about 5 hours active or only standby).

    • Hi, at your situations the problem can comes from either your hardware or from the battery at your Lenovo K900. If the problem happen at your phone hardware and it can not ON, then the hard reset using hardware button will not run. First you can try to change the charger with other Android charge (use minimal 1 A charger), charge about 1 or 2 hours, if the phone still can not ON, then you have to bring your Lenovo K900 to service center to check more for the hardware problem.

  7. My Lenovo K900 suddenly truns black and wont start up even on pressing the power button for several seconds, only the bottom three lights keeps flashing.
    When I connent it to the charger and press the power button it starts up and works normally until the charger is connected. once the charger is disconnected after few mins of usage the screen would again turn black and only three bottom lights will blink, even when the battery remains above 90%.

Try to do hard reset while your phone can use normally after connect to power charger. Find menu Setting > Backup & reset > Factory data reset. Hopefully this master format steps can help your phone back to normal again. If the problem still happen, then maybe you need to bring to nearest Lenovo service center for further check
