I switched to 12.5 ROM like a year ago after Xiaomi didn't deliver it as an update from the stock 12.0 ROM as they promised. I first checked the Google Pixel OS and did not enjoy the extremely basic UI then decided to turn back to MIUI since I actually like how it looks. While I was at it I decided to load the latest version possible.
I rooted the thing to experiment but ended up not being able to find much to gain with it since it is a failed product that didn't sell well, there were not many software stuff for it. Anyway out of curiosity I recently installed 3DMark and it performed very bad compared to average score. It looked like it wasn't boosting to max clock speeds so I tried forcing it to max clock speeds for both GPU and CPU with root Android toolbox. This somehow made it worse and get 800 points which is only better than %1 Mi8 phones that finished this test. So I reverted the changes and got the same 1140 ish score I got before. Tried testing it again while it was plugged to the charger with no difference. Max temperature was 33C which makes me believe it is not boosting to right clock speeds.
To be honest phone still feels ok to use and battery life is enough for me since I recently replaced the battery. So I will not be installing another OS if it is the only reason for the low score since I don't really care benchmark scores as long as I have a smooth experience. But I would like to know why it is so bad and if there is a way to solve the issue without re-flashing the whole thing. I also don't want to re-flash it since last time I tried loading back the stock ROM from the whole backup I created and it somehow randomly failed in the middle of it and corrupted the partition that was responsible to making it connect to SIM and Wifi and it was a pain in the ass to figure out what happened and fix it from the old save file I had.
I am also very bored by using this thing but don't really want to buy a new phone while they stagnated this much over the past years in terms of technological advancement. I am planning to make a custom 3D printed back for it and install like a 10K mah battery to BMS board of my old battery and unlock all the clock limits on the software to fully unlock its potential. Does anyone know where can I get a CAD file for this phone so I can design the stuff I need for this.

24+ Hour Battery

when DC v2.08.1 came out i downloaded it just like all the other DC ROMS prior. At first i noticed some improvements in battery and performance, but after a few days of using it i decided to check what has been using the battery in settings.. this is what i came across

crazy thing is i hadn't used the camera that day... i monitored it for the next few days and still no matter what i do on the phone throughout the day, it always shows these same stats.. the great thing about all this is my battery would last past 24 hours no matter what i did on the phone..
i ended up flashing DC v2.09.1 (cause im a flashaholic) and couldn't get the same results.. well i decided to nandroid back to 2.08.1 but i lost the battery performance i was getting before... when i checked whats been using the battery, it would show normal things that i've used and cell standby and phone idle would be back to about 40% each... so i decided to wipe and reflash DC v2.08.1.. low and behold, after about 3 days, its back to 96% camera, 2% cell standby, and 2% phone idle.
my question is does anyone know how, or why this is happening?? im loving how long my battery last and the speed of my phone because of this.. i just wanna make sure it stays like this.. or maybe how to make this happen on other ROMs cause im sure im gonna flash another one again soon...
(oh and by the way, im not missing any phone calls, text messages, or emails.. everything is working perfectly)
It happened to me a few times while on dc, rebooting would set it back to normal.
I read around here somewhere that ir wasit was a sense bug..i forget where...
I don't have any useful information sadly.

rebooting doesnt change anything for me (which is a good thing)..
Now that you mention it, I had the same experience, yet didn't realize it at the time, being new to rooting/roms/etc...i have lately been using stock 2.1 rooted without updating..and really noticed the difference in battery life. Got me thinkin' now.

2013 Lollipop Performance

I saw the Lollipop performance thread, but it seemed mostly focused on the 2012 model, so I wanted to start a thread to air out some issues I'm having on the 2013 OTA. I sideloaded the OTA, and my tablet is encrypted, which may be contributing to these issues, but I have to say that performance is poor, bordering on abysmal.
I see stutters and lag all the time, even on the simplest tasks like drawing the notification drawer animation. Actions like returning to the home screen are brutal and sometimes take measurable time. Sometimes apps just slow to a crawl and the tablet seems to lock up for a bit before it figures out what it was doing.
And over the last two days, I've noticed completely brutal battery performance, including this garbage:

That's a day of the tablet sitting on my bed not being used. I think there was 35 minutes of screen time. The battery stats are useless: 11% Android OS and that was the highest. Nothing else, no miscellaneous or anything like that.
I just cleared my cache partition, but it's still being sluggish. Any ideas on what the hell is going on here? It feels awful and the tablet was really pretty damn decent before this update. The battery life was just fine: 85% or so if I came home from leaving it on the bed all day.
Likewise, are there any better battery stat apps I can look at that can help me get to the bottom of this? It feels like bad battery and bad performance could easily be related if something is grinding in the background and keeping a wakelock active and I have no idea.
Anyone else having an awful time of 2013 5.0? Anyone see a performance increase?
Seen the Nexus 7 2013 forum?
If not, try it out.
From the planet Compact
By way of an update, clearing the cache and a reboot seemed to have helped significantly. The weird battery drain is gone, so that might have just been a runaway process or something, and the overall feel of the tablet is back to being much snappier.
Dont know why i didnt think of clearing the cache. Performance is where it chould be now. Thanks!

Optimus 4X HD - Thermal & Energy Throttling

So, as we all know, our beloved Optimus 4X HD can get really hot after heavy (or even light some times) usage. Being "inspired" by this guy, I wanted to investigate and find out:
-how much impact does thermal throttling have on our performance
-how much does Screen Brightness affect the thermal throttling
We have all seen the "Can not increase Screen Brightness due to high temperature" message on Stock. Did LG have a good reason for restricting us on that?
Finally, once I started doing the first runs, I noticed some really unexpected results... So, I tried to deepen even more and try to figure out if:
-the battery percentage impact the performance
The testing procedure was the following:
I kept running the Geekbench benchmark repeatedly for 30 minutes and taking note of the Multi-threaded score.
For the first set of runs I had the brightness decreased to Minimum. Then I charged the phone to 100%, left the device untouched for about 10 minutes (in order to cool down) and ran the test again with the Screen Brightness set to Maximum. Finally I did the same tests with the battery around 50%.
During the tests my Optimus 4X HD was:
-CyanogenMod 11 - Snapshot M10 (Android 4.4.4)
-No custom kernel
-Fully charged (1st go)
-Half charged (2nd go)
You can see the results on the following graph:

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
You can clearly see that battery level actually has more impact on the performance than temperature.
What questions does this answer?
Yes, Optimus 4X HD does throttle(as if we didn't already know that). Yes, screen brightness does matter. Yes, the device is faster when it has more juice left.
So guys, what do you thing about all this? Does throttling matter to you? Did you get different results on a different ROM/kernel? Do you think that buying a new battery would actually improve the performance of the device?

Battery Cliffs

Someone asked a similar question, but the last reply is a year old and the last reply was about settling. I don't want to just settle if I don't have to, I'm curious as to why.
Decided to try using a Droid 4 again, and I've been running into what killed me off of it in the first place: serious battery level issues.
It seems that every custom ROM I try has a broken battery meter:

This is CM 13 or 14 (Marshmellow or Nougat), I don't remember. Was actually looking for a different screenshot and realized that this had what I needed too
(I dont know CM versions as well,so please excuse me if I'm naming them wrong)
I'd say that its a battery problem, but If I go back to stock this doesn't happen (90% sure on that. I'm in the process of doing some more testing and actually documenting things. Wanted to toss something out while I wait for file transfers to see if anyone else gets this.
I think I once used a modified stock rom and it worked without battery cliffs either. This is my second D4, and the first had the same jumps in battery too.
To be fair, the same thing started happening with my HTC Thunderbolt, albeit on stock and a bit more drastically.

Try resurection remix it works pretty good on my droid 4. Its the unnofficial version ported to the droid 4 by transil. It is in the development section for this device. Also if you use bettery battery stats you can get the apk here on xda. You can use this apk to see what is draining your battery.

General Android 12 Beta 5

I would love to know everyone's opinion that is currently running Android 12 beta 5. I'm getting the best performance and battery life of just about any phone I've ever owned but this is also my first Pixel device. I also find the UI of Android 12 to be quite striking and a bold move in the right direction for Google. I will upload some screenshots of my benchmarks and device set up for those who are on Android 11 and curious about the beta's performance/aesthetic. Anyone else on this firmware please feel free to leave your thoughts/impressions/concerns in this thread.

agree, I like it as well. Although, I think the 5a could be just a little bit faster. Sometimes it's a little sluggish. But I am spoiled by S21Ultra and OnePlus8 Pro which I don't have anymore. The battery life is stellar. Sometimes I get through 2days before I have to start charging.
cheers

What happened to your OnePlus and S21 Ultra? Just curious.. I can relate though my previous phone was an LGV60 so I understand about the speed.. this is my first "Mid-range" device but I have to say aside from the speed/processing power of the V60, I think this Pixel 5a is superior in every other way. I'm definitely excited to see what kind of developmental support we'll be getting as more people get their hands on the device. If its already this good on stock android, I can't wait to see what this phone can do on a custom ROM.

I sold my OP 8Pro to buy the S21 Ultra. That was my downfall....
there is a long thread here that explains what happened to me with horrible Samsung Support story. Bottomline, screen had manufacturing problem and it took me 4 months to get my money back and it involved the consumer court.
I really like the 5a, don't get me wrong. It runs the latest Android, which I would not be able to do on the OP 8Pro or the S21 Ultra. The camera is wonderful. The sluggishness is mostly due to the fact that I got so used to >90Hz refresh rates.
cheers
What to expect and when ? And are we going to see 4.1 like we did with beta 2&3.
