Is that after doing a full charge? Any indication from the seller if the battery has ever been replaced? To calibrate the battery you can run it to nearly zero and then do a full charge.
Idk, i will ask seller then, but now after 2 times back to 16% it seemed it depleted normally, now it can reached below 5%, should i recharge it or wait until deplete completely?
Updated,
1.now back to 7% after it reached 4% what happpening, so confused here
2. It raised to 8% from 7% after a couple sec
3. Suddenly down to 6%..
