Looks like your battery gauge need a calibration. While Lithium battery installed in i5 does not have memory effect, it does has what we called inaccurate gauge issue, and this problem is quite common when a battery has been idled and/or drained for a long time. If you run into inaccurate battery reading or sudden power off when the duration period didn't add up, I suggest you do a gauge calibration to verify the problem. In fact this is something that we all should be doing occasionally. I normally do this after 15-20 charging cycle (2 times 50% charging is count as one cycle) An inaccurate gauge can lead to the fact that the the battery capacity values are are wrong. The battery may report that it still has reasonable capacity when in fact it has a much lower value, and this causes the computer to shutdown unexpectedly. You can google the terms "Calibrate Gauge" on Lithium Battery.anyone experience auto shut down of cayin i5 ?
for example i left it on idle with song pause for 8 hours or more like overnight or when i am working,
when i try to light up the screen after that nothing happen (which i had to power it up again ) with battery remain
idle shutdown : off
scheduled power off : off
this happen 3 times this week
To calibrate the gauge of a lithium battery, you simply need to do a full discharge followed by a full charge, so this is what I advice:
- Turn on the LED screen to maximum brightness and set the screen to "always on", keep it running until the player turn off itself.
- Charge the battery overnight, till you see 99% or 100% on the meter
