[Q] Massive performance drop from 4.2.2 .290 to 4.4 .757 - help?
So... I was running NUT's stock rooted .290 (Android 4.2.2) and used to get Antutu scores around 35K.
Yesterday I finally bit the bullet and upgraded to .757 -- again, NUT's stock release, just rooted. Upgrade went fine (I've done this before), phone is stable and I am enjoying KitKat, BUT performance is downright terrible. I get 22,000 Antutu now!
At first I thought it was because the phone was hot after the upgrade and throttled back, so I repeated the test again several hours later when it was cool. Yes, that improved things -- to 25,000! Still a drop of 10,000 from what I used to get before. And it's not just the number -- the phone feels slower in use, too. Got a massive drop in Anomaly Benchmark too, so it's not just Antutu.
Again, both times are on NUT's stock rooted builds, no tweaks or weird things done on my part to "improve" the device. Attaching screenshots.
Can anyone running KK .757 do an Antutu and tell me what they get? Any idea why this is, and what to do about it?
EDIT: Sorry, title should say "from 4.2.2 .290", not "from 4.3"
