"Battery care" not working with third party charger?

[Alanslade]

Good morning.
I bought an Aukey Quick Charge 3 charger, and I'm charging the phone during the night. I think that the feature "battery care" is not working properly, because I woke up at 4:00 am, and the phone was already at 100, when according to the "battery care" feature, it should reach 100% when I disconnect the phone at 7:00, the hour when I usually wake up.
Anyone noticed this?

Did the battery care pop up when you connect the charger? 

Did this happen more than once?

I don't know, I connect it when the phone is shut down.
I think that it happened more than once, because even at 6:00 am in other days the phone was full charged

@Alanslade: the battery care only works when the phone is turned on.

when you connect the charger it should give you the time estimated ( as you have already stated), but leave the device turned on, do not power it down.

Seriously? Only when it's on?
I always charged my phones when they are off to prevent battery consumption.
So this feature is a little useless I think

In my experience phones consume a lot of battery powering down and up again... you are better off putting your phone on "flight mode" during nighttime to save battery and disable it in the morning.
