Strange battery behaviour

Hi everybody,

in the last two weeks i recognized reproducable, abnormal leaps of battery charge. At about 65%, 55% and 40% the charge decreases within a minute by 4-5%. Otherwise i sense that sometimes there is no discharge for an unusual long duration, but this is only a feeling.

The battery is in use since five months and i’ve accurately took care about healthy. It has been a rarity that charge was below 30% and even so over 80%.

In the last few days i tried to do a recalibration (discharge to 1% and afterwards charge to 100%) and i removed the battery for a half an hour. But this hasn’t improved the issue.

Does someone have an explanation for this issue or a possibility how to fix it?

warm regards,
Pat

Have a look at the battery guide.
