Boot loop and charging going on and off continuously (Z1 Compact)

I have bought a secondhand Xperia Z1 Compact. It has two problems, which I am quite sure are related:

1) When the battery is fully charged (green light, 90+%), the phone will continuously (forever loop) restart to the Sony Xperia screen when it is turned off using the power button. If I hold down the power button and volume up button, the phone will turn off properly.

2) When the battery is fully charged (green light, 90+%) and charging (towards 100%), the screen continuously comes on and goes off. It seems like this happens because the charging stops and starts (the charging sign next to the battery comes on and off).

I have been using Android 5.1 and Android 4.4.4 and the symptoms are the same on both versions of Android.

I have used different cables and chargers. The symptoms are the same on all cable/charger configurations.

I have used Sony Companion to repair, and Flashtool to flash different versions (stock) of Android. The problem persists.

Any ideas on the causes and/or solutions?

Your battery is simply dead.
