Guys, I actually wanted to do a video to solve this but I just can't find the time. To solve this you will need to recalibrate the battery. Follow the instructions below :

1. Let the phone run until it shuts itself off.
2. Without turning the phone on, plug it in and let it fully charge up. (It will show full green battery image)
3. Unplug, turn the phone on and let it run flat again. (Without connecting to charger the whole time)
4. Battery and battery stats are now recalibrated.

**NOTE**
After recalibration, with Smart Endurance on, my phone can last until 3-4% and shutdown itself with the Lenovo boot up animation, only in reverse.

Take note: Dont do this often...
Li-ion battery are not design to drained to 0%...
It might kill the battery instantly...(Some might survived it)

Do not worry as Lenovo's software will force shutdown when you reached around 3-4% by displaying the shutdown animation (if your battery is calibrated properly). Those who self shutdown at around 20% (like what happened to me previously) will not show the Lenovo shutdown animation. It will just turn black prematurely.

This is mostly due to eager owners (myself included) who straight away charge the phone and turn it on to play with it  after they buy a gadget. Proper way is to let the device charge fully without turning it on during the first charge. That way the battery will be properly calibrated.

Thread Starter,

Is it possible to put this little info on the first page?

I went to the service centre today to send my k900 for warranty claim.

Just for everyones info, according to Lenovo's website, the service centre is BrightPoint. However, they are using Ingram Micro Mobility name. This is so that its easier for u all to find the service centre. thanks

Now charging, but I dont see any sign of charging leh, other than first 1-2 minute. Is that ok

Another case of cannot charge. I think this phone has problem with the charging function.

I think is charging, can feel some heat .  But charging disappear d

Open Lenovo Power to see charging status.

I thought u said don't on the phone ?

I see, you mean no status while turned of charging. You can actually bring up the status by quickly pressing the power button. Don't hold!

For me, i had to plug into pc then u can see the option. Fastest way.

Hi! I just bought this phone yesterday.. Just wondering is it normal that the battery drains like hell? D:

Also the knock to light feature. How does it work. I knock nothing happens?
