Battery charge drops suddenly + strange gaps

[Nin]

Hello!
For a few weeks now, my fairphone 2 has been losing huge amounts of charge (up to 50%) suddenly and also shows gaps in the battery usage graph (also it keeps dying for no reason, seemingly, and only starts again after removing the battery, putting it back in and turning it back on but that might be a different issue)
I’ll include a screenshot of the battery graph!
Thanks a lot!!!

As you can see, it drops suddenly after 19.00 o’clock.
