Guys, have anyone tried letting the battery drain to 0%? Mine will shutdown somewhere around less than 20% and then unable to turn on. When plugged into charger it will indicate empty battery.

I'm now trying the Smart Endurance in Settings and see if it helps.

I'm using the default File Browser and AirDroid to transfer files between phone and PC wirelessly. If you want to manage files using the phone while still connected to the PC, do not select "Mass Storage (UMS)", select Media device (MTP) instead.

Did you turn on Smart Endurance?

I use custom setting to maintain all services even when battery goes below 20%. With Smart Endurance turned on it was better yesterday because it is able to go below 20%. When it got below 20% I tried playing game, Minion Rush to try to drain the battery faster. Halfway, I got the 15% battery warning pop up, which is good. I ignored it and continue the game but around 5-10 minutes later the phone shuts down on its own, battery was flat. I don't think Minion Rush is that power intensive. Today I will try letting it drain naturally, but with a non-removable battery, timing is really difficult when you need it fully charged for the next day.

Jeez, latest Real Racing 3 version 1.3.0 can't even start the game.

Finally my K900 able to shutdown by itself with the Lenovo animation (same one during startup, only in reverse animation) at 3%. Looks like battery recalibration and Smart Endurance works. Let me monitor too see if this is a 1 time occurrence or a permanent thing.

Guys,

Look for me if interested for original K900 screen protector imported from China at RM15/pcs.

Try going to Lenovo Power -> Mode -> Custom Mode and configure to what you want.

Check the switch mode settings in Smart Settings at Lenovo Power -> big "S" on the top right.

Most probably AC adapter issue. Try charging using different AC adapter.

After 10 minutes of charging with Nexus 4 charger, still the same. 16%.

Hmm, that is unfortunate. Do update us what is the issue with your unit.

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.

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.

Open Lenovo Power to see charging status.

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!

No need factory wipe. Did you turned on Lenovo Power -> Smart Endurance? For me I flushed twice just to make sure. battery flat -> full charge (phone off) -> turn on (don't connect to any type of charger until battery empty) -> battery flat -> full charge (phone off).
