[Sony Xperia X Compact Questions & Answers] realtuxen:
Heys, finally some peace. :)

I received the .273 nougat update yesterday (or nearly 2 days by now. heh), and have been testing and poking around a bit since.

my conclusion is there is nothing wrong with the cpu behavior at all, except for some apps cant read their value properly, likely due to a read only flag as suggested earlier in this thread. not even developer options cpu usage show things properly. the new dialer app is absolutely horrendous though.

anyway i took another approach and installed termux (a small Linux like shell where you can apt-get a few tools) and ran top and pressed 'c' to have a look at all cores. i ran termux in one window and any app in question in the other.

this was of cause after a screen off and cpu-z shows them as off, but according to top all cores are running fine. i then proceeded to test with the new geekbench 4 that i had tested with on MM and that is updated to show a more likely day to day performance on new processors and old thermal throttling processors better.

starting with the single core test one a72 core spiked full usage, and halfway through when it comes to multi core all cores both 4xa53 and 2xa72 spiked full usage. i read here on xda in an interview with the geekbench devs that they actually now pause a little between some activities to better show the notoriously overheating cores on sd 810 devices in real life usage, which also can be seen vaguely. anyway nothing to come after there everything looks fine and i got the same scores:

1391 single core on MM, 1344 on N.

3355 multicore on MM, 3426 on N.

a little bit higher on nougat but these scores usually swing a bit from run till run.

btw: z5c has a multicore score of 2717 vs. the 3426 on xc :p

now on that is out of the way (cpu's are active no worry's) on to my own real life experience; as said i updated yesterday morning (or the day before now as you can see here, time flies). in general usage i can not get it to lag in notifications no matter how many i get all is smooth. i set the phone to keep them unless i swipe them and let them build up during the day, and cpu usage show no more than a few % on all the cores also the 2xa72. i tried every move that i usually make i MM only harder (scrolling in notifications, email, messages, chrome, homescreen, etc) but i must say its exactly the same no lags at all. i only had 2 games installed minion rush and real racing 3 (i installed them when i got the phone just to test the game performance). MR is the same, i would not expect otherwise. RR3 is for also the same with good 'in game' speed with no lags/framedrops and some framerate drops on 'replay race' in camera angles placed along the track and with a few cars zooming by. again like before.

now on to the ugly dialing app, mine did not look or behave like that on MM the call log was flat and not dynamic as it is for some unknown reason, it had the same call log functions but it did not show contacts. i had to press the empty search box and was then taken to contacts. in N the call log is like small dynamic notification boxes and yes it lags violently. let me explain what i mean by dynamic; when i first go to it or scroll down some name are shortened like the box says 'fi...' and after a sec or 2 it expands and shows the full 'firstname lastname' the same happens with unknown phone numbers first it might show '45..' then expand to the full number, some call boxes does not even expand at all before you press them. very odd behavior and my 2 cents to why it lags. it does not stop there try go to contacts (in the dialer app ofc) and pick a contact you can see in the status line that it switches to contacts app and back this gives an impression of blinking and a lag too. if i measure the cpu usage again its no where higher than roughly 15% at times and again the a72 cores are active. i really do not know what sony did to this app it is screwing with the gui.

i tried showing gpu usage on screen in developer options too and this seems normal again when scrolling through stuff, there is the usual high gpu spike when you change screens but that's normal on every device i have tried also with higher specs. EXCEPT again when it comes to the dialer app, it spikes up and down like crazy.

if anyone have anything else that lags i be happy to investigate, but for now i see nothing wrong with nougat in terms of performance. there is some weirdness besides the dialer app such as the reporting of 'big' cpu and the state to apps, geekbench 4 also saw the phone as 1.4Ghz in MM though. however this is cosmetic but non the less something sony should fix.

much worse is the dialer app that seems like a bad hack especially flipping back and forth to contacts app instead of integrate it properly. that and ofc the odd dynamic call log boxes. because this is what we see in daily use, sony should really fix this asap. i cant understand how this got through. the app in MM was much better why the heck did they not keep that until they had a proper app is beyond me.

i have some questions too though: did anyone have the same dialer in MM as in N? did anyone get their home launcher updated for grid size and removing icon size setting? i did not get it and i already had the google now integration that i also read about some first getting in nougat. also i had the manual shutter speed/focus and the enhanced stamina settings already, the only real new feature was multi window, cosmetics (notifications, battery left, quick settings) and ofcause the lousy crap dialer.

btw. battery time seems the same with 40 hours since last charge, only 5 left, and 8 on screen hours. i guess it can be a little better i got hooked on real racing twice which accumulated to 67 mins. i got more on MM but that is without playing games and i can see a big dump twice on the battery curve which as said is nearly depleted with 11% left. i have never been this low, and i usually charge every second day and never use stamina. also i do not use social apps such as facebook, scatchat, twipper, or what they are called either. :) i will continue to report if i see anything and also as said feel free to guide me to where you see lag.

leggy then it must run fast. ;) i just installed it on my last battery time, and no it does not lag at all its very smooth. i would be very surprised if such a simple game lagged. i find those candy, soda whatever games very annoying though so it wont stay. but now its tested another time do not listen to trolls. :)
