Vass66, I answer to you here instead of in the weekly rom thread.
When the change to TWRP came, I didn't do the first update (was waiting for OTA, which didn't come), so later I updated to 6.3.3.
To do that, I had to first install TWRP, which I did downloading the version from the first post, and installing from updater app. Then, I did the same with the 6.3.3 file. All went well.
I skipped the next updates.
Now, I was trying to do exactly the same with the rom file 6.3.25, but the process was aborted at start... I tried twice.
I then tried to reinstall TWRP (the same file which was already in my download folder), and repeated the process with the rom, and all went well.
The TWRP was the same, so my only guess is that this reinstallation overwrited the previous and its settings... And the only non default setting that I had changed was the time zone - I changed it from default (I think it was gmt-5) to my own (gmt).
So it returned back to default.
About wipes, this time I didn't do any, and all went well.
On the previous installation (6.3.3), inside TWRP, I had done a full backup, then wiped cache and dalvik, then rebooted and update from updater app.
This time I only did a full backup, no wipes.
About the battery it's too soon to tell, but it seems normal or better.
But the antutu score was frankly better than the last one I did long ago... I remember it was around 21000, but now is above 26000. Same antutu version.
Are you having problems updating, or just asking before trying?
Hope I helped you.
