@ToxyPoxy said in Sony Xperia X (suzu/F5121 & F5122):

1. Updating to Android 8.0 isn´t that something you can do with Sony Emma Tool easily?

Well... I was optimistic and tried it without updating. I don't have windows installed.

2. After I installed Lineage OS on my Xperia X Compact I had much more battery drainage than before.

So how long last a full battery in idle mode wifi and mobile on?
