Bought a second hand MBP A1708 2017 a few months ago with defective motherboard. Repaired it, worked on it a few weeks and the machine works very well as a macbook should do. (Battery time in standby was about 20-25 days)

Replaced the original 128GB SSD by an 512GB SSD from Ebay (China). In fact an adapter + 2242 nvme.
Works well, but in standby my battery drains in 2,5 days.

This is a very similar problem just like in the 2014-2015 MBP retina widely described here. Lots of solutions for that type.

Are there already solutions for the A1708?
Thanks!

What happens if you power it OFF?
Will the battery hold its charge that way?

Sometimes, one has to do, what one has to do...
 
When you power it completely off, the battery stays charged...
Working time is normal (around 10h depending what you're doing.)
 
I have the same issue. I upgrade ssd to sabrent 1tb.
From system log, pretty sure macbook enters standby.
But it drains battery about 2% per hour.

Check activity logs? Maybe an app is still running that is causing the battery drain.

If it doesn't drain when the MacBook is completely shut down from the menu, something is keeping the MacBook from fully entering standby.
 
There are indications that the SsdPmEnabler kext, which was made for power efficiency for NVMe installations in 2013-2015 rMBP (and 2013-2017 MBA) also works with A1708.


So it may be worth looking at that thread and trying the strategies used with such machines (SsdPmEnabler is not the only kext that is adopted for power efficiency).

An entry point for SsdPmEnabler is at this post:
