I/O Scheduler Storage Benchmarks

Okay.... here we go!

Basic knowledge about I/O Schedulers

App used: AndroBenchmark 4 (former Storage Benchmark)

Settings:

Target Partition: /data (internal NAND)

File Size: 64MB

Buffer Size Seq: 32'768KB

Buffer Size Rnd: 4KB

Threads: 8 first run 32 2nd run

SQLite Transactions: 1024

Every testrun has only been made once! Sequential and Random Read/Writes are doing 3 runs anyway.

Sony Xperia Z2 with 4.4.4 Stock .167 ROM and Androplus v21 Kernel.

My internal Memory is 9.82gb Full and 2.88gb Free!

CPU clock was NOT fix, so i/o scheduler which limit to the cpu cycle might do worse than under real heavy lod.

All Screenshots made from the Results can be found in my Picasa/Google+ web album: here

And here we go!

Sequential in MB/sec (Higher is better)

Random in IOPS (Higher is better)

SQL in TPS (Higher is better)

Macro Benchmark in msec (Lower is better)

Conclusion:

Except BFQ which is obviously broken in Random writes most I/O-Scheduler behave similar. Only when using 32 threads, you can see differences.

SQL and Macro benchmark was only made once and is therefore not fully trusteable.

If you now ask "Which one is the best?".... i have no idea!

Each test was ran 3 times rapidly and it seems that sio as usual proves its stable above all

I did some null tests just to intentionaly increase avg load so that way all the tests were fair as posible

I pulled the best results (worst was most of 8mb less of these screenshots)

So as you can see sio is the fastes but Zen and tripndroid are more stable and require a smaller read ahead cache

Conclusion:

Sio is best for overall use

Zen is sort of a better sio

And tripndroid is more stable then the two above

the few others i didnt show here werent reliable the results varied too much

However noop was slow but stable
[Xperia Z2 General] sh4d1t0:

but for 15$ which is still cheaper as the original Sony i can totally reccomend this!

Now i've just gotta rebuild that brocken Dock which i've bought for 7$ xD It's nothing other than a magnetic cable put into the right direction fixed inside the dock xD

Do you mind doing a benchmark for Alucard + Hyper? :D I seem to get better battery life with intelliplug + wheatley rather than alucard + hyper, but I have no basis for that. According to the Android Modders Guide (http://androidmodguide.blogspot.com/p/blog-page.html) Hyper is "best" for Multicore balanced for gaming and battery life and wheatley is just "good".
[Xperia Z2 General] Haldi4803:
Alucard Hotplug is a user defined hotplug similar to Fast_Hotplug from Pec0ra depending on what values you have set it will act totally different.

The Governors have their specific settings to increase speed on certain conditions, i.e. load over 90% for 100ns. if the hotplug now activates a 2nd core the load balances over 2 cores and doesn't reach 90%, if you activate a third core the load decreases even more resulting on lower CPU clock.

So you hace to test the same cpu governor with every change you make in the Hotplug.

If you want a fair comparison you need to test every governor with every Hotplug setting you make. and that would take years ^^

But i'm gonna take a closer look and a few tests with alucard for sure in the next days.
[Xperia Z2 General] iArvee:
I see. Thanks for clearing that up! Seems like I'll also have to read up more on hotplugging (esp. Alucard) and do my own tests. :D

Sorry if I sound annoying but there is a spelling error on the latest cpu governor drainage table (should be smartassv2. not smartassv3). Anyways, I've used your table for my website and my guide, of course with full credits to haldi himself. Thanks! :)

GPS Navigation via Google Maps

i was driving about 50km trough the countryside today and tought i'd use this chance to make a GPS Powerdrain Benchmark :)

Google Maps Navigation works fine even with screen off (you can see in the graph, the first 5-8 minutes were with screen On, then off) You only get Voice notifications on where to go. Google Maps uses GPS and Mobile Data but does all the calculations in the cloud, therefore no hughe CPU load.

It took roughly 57 Minutes and the Battery dropped from 85% to 78% (ca. 7% per hour).

The average Powerdrain was 1.16W

(right click view image for Original size)

The Graph shows in Blue the meassured value (every 100ms) and in red the average over 25seconds.

There should be a TimeIndex at the bottom from 0 to 57 Minutes.... but well.....

If you have 22'066 Data Points in 57 Minutes you can set a Maximum Space of 255 points (again these 25 seconds) meaning you have 2 numbers shown per minute, aka 114 values on this short graph.... simply to much!

The "cleaned" average with only Screen off powerdrain would be 860mW

So I tried to read all the tests and to be honest, I didn`t understand a lot of this.. I am with 5.0.2 .726 lollipop and thinking to unlock my bootloader, to go for any kernel I want and trying to reach best performance for my phone. I personally need more battery life, because it lasts me one day, for 4hrs of screen time. So what I should do really to get amazing experience for my z2, like others have?

Review: External Battery Case

So after long time i've invested 20$ and got this 4500mAh external Battery Power Case.

I've got mine from AliExpress (Link here) it arrived roughly 12 days after ordering.

Why did i go for this 4500mAh version and not any other 3500mAh charger out there? Because this model here says it can charge 5V with 1A, while most others only do 0.8A (in comparison sony's EP880 Wallcharger does 1.5A). And the Test's confirm this. The phone itself with Screen on uses about 400mA charging with the dock you get about 600mA charging using the official Wall charger you get about 900-1000mA, so Yes, it does indeed have an output of 1A.

So how much does it charge? i managed to get my phone from 5% back to 93% that's quite something. Altough it took 3.5hours

So here we have the standard Graphs for Charging :)

it's roughly 40 minutes slower than with the Magnector X cable i normaly use to charge my phone. Pretty impressive.

So, whats the bad points?

A: It takes ages to charge to Case itself. roughly 4-5 hours, did not meassure that exactly.

B: it's not healthy to store a battery (cover) with full health. If you don't use it over longer periods, make sure you only charge it up to 75% So you still have to re-charge it to 100% right before going on a longer trip.

P.S Here is the Manual that shows how the 4 Lights on the Backside work.

Oh yeah... it has a Powerbutton, so you can actually use the Case without charging.

AND it's said you can charge the Phone and Case at the same time. Gonna try that the next time my phone is empty.

Edit: Yes, you can really charge the Phone and the Case at the same time. it simply takes ages ^^

Roughly 7 hours to charge the phone! But after that the dock will also be full.

On low battery it charges really fast between 1.6-1.7A but then when it get more % it goes slowly down to 1.4, 1.3, 1.2 etc. Hehe I used the phone a bit while charging but only max 5 minutes. I think thats waay faster than your stats. LG G2 charger 1.8A with magnetic cable. I started around 12% I think. I think there is a better charge possible that wasn't the maximum I've got out of this hehe.

AndroPlus Kernel V58a

So.... i've heard of internal GPU Logs to record Time in State and Transitions :D

Especially with AndroPlus Kernel v58a's included "Adreno Idler" i've had to test this out. Sadly i did not have benches this before using v58a, only long time ago when i made some Benchmarks #54 i also recorded GPU usage (via Trepn profiler). But it seems like even then Our Z2 would clock down to the lowest GPU frequency without any problems.

So, how long did i test? The whole time. After fully charging my Smartphone i rebooted to reset the stats file overal_time_in_stats and trans_stats and continued to use my phone normally during the day.

It survived 1.5 days with 5h30min SoT, usage was mainly web browsing, TapaTalk, lot of emails, some whatsapp and few hours Yatse media control widget showing.

Due to this "Awake" time and wakelocks the GPU and CPU have been active for 7 hours 45 minutes.

The Active Time measured in GPU and CPU stats also confirm this value:

(a Transition means a jump, i.e did the GPU switch from 23'729 times from 27mhz to 657,5mhz and 21'971 times back from 657,5mhz to 27mhz.)

Funny thing to see is that in 2/3 of the cases the GPU jumped from 27mhz directly to the maximum clock of 657,5mhz and only 1/3 of the time it jumped to 100mhz. so the msm-adreno-tz really likes to go all out ^^

Oh yeah, another important fact: During these 7hour45minutes the Screen has only been activated 5hours 30 minutes! so 2hours 15minutes have been active with screen off, MOST LIKELY during these 2h15 the GPU frequency has been 27mhz.... so the 62% in 27mhz probably wouldn't be that high without wakelocks.

Looking at the CPU chart we see this 2h15min also affecting the 268,8mhz frequency.

btw, based on the completly wrong and irresponsible assumption that the phone does not drain battery while it's in deep sleep and we have a 12Wh Battery one could say that the average Powerdrain for 7 hours 45 minutes would be 1550mW saying that the Batterydrain would only happen when the screen is online (5 hours 30 minutes) this would be 2180mW.

In this Char here we even have Transitions included on the right side: (Jep... exact same Values as the Barchart before, just different axis and stacking)

Funny thing is, there are about 570'000 switches on the Core0 and about 330'000 on core3, compared to the time online (100% for core0 and 40% for core3) there are way more switches on core3 than on core0, 1 or 2.. well.... interactive governor doing it's stuff with MPdecision together....

So after the phone went empty i charged it.... with an EP880 1.5A charger... no changes here... all like allways.

important note:

This is D6503 no the Japanese SO-03F, so this does NOT Support Quickcharge 2.0 the faster chargign time comes only from the 2.0A current instead of 1.5A.

(altough i have to admit i did not yet check this! Simply charged it without any measurement :angel: )

i will connect my Voltmeter and modified USB cable the next time and check if i can also charge fully in 150 Minutes, hope my camera does last 150 Minutes to make at least 300 fotos...

We have come a little bit Closer

So using Modified AndroPlus Kernel v63 and sysmon.cfg edited by Jackos (rev4) the devices charges again faster.

Using the YZX Studio Power Monitor i can see the QuickCharge2.0 working at 9V (img) we can also see the charger drawing about 8.8W (img) the Charger is supported up to 15W, now we're trying to pump these into our Z2 :)

As you can see in the Picture the Charger provides 8.8W in 9.1V and 0.97A, in the phone this will be converted into the charging Voltage (which should be around 4.3 or 4.5V... no idea.... really) Let's assume it's 4.5V so 8.8W would be 1950mA, Ampere saying "charging with 1690mA" would mean the device is currently using 260mA which might very well be true.

The YZX Studios Power Monitor does have a Log feature (firmware 2.5 needed) if you connect it to a Computer via Serial or Bluetooth. I haven't done this yet, will certainly in the near future, therefore all Stats shown in the Excel Graph are made by internal Log via the BatteryLog App Voltage= Battery Voltage and NOT charging Voltage!

Fully charged, how much can we fill in our Battery?

14.5Wh we need to charge our Battery, theoretical 3200mAh x 3.8V would be 12.16Wh, so we lose about 2.34Wh due to charging inefficiency.

Wall of Text over... let's get to the Results!

130 Minutes for a full load... from 1% as you can see in the graph the battery voltage was dangerously low, below 3.5V

(That's exactly why you should NEVER use your phone under 5% Battery if anyhow possible! Not healthy.... not healthy at all)

You can also see the battery Temperature droping after 75% / 80 Minutes, if i would have the input current, most likely that would also drop right then.

i have absolutly no idea what that crazy spike at 22 Minutes is.... and ideas are welcome ^^ I did not use the phone during charging, but i did see 6 updates were done when i came back.

So yeah... this is nowhere near the Qualcomm's claimed 60% Charged in 30 Minutes (took 60 Minutes) but this is still the fastest charge ever achieved on a Sony Xperia Z2 International.
[Xperia Z2 General] Haldi4803:
Fully Working QuickCharge 2.0

So using Modified AndroPlus Kernel v63c (with 2150mA limit) and sysmon.cfg edited by Jackos (rev5 15W on USB) makes it fully working.

The phone draws about 12.5-13Watt from the Charger.

Sadly no exact statistics yet.... i will get the Bluetooth module for the charger in the next week then i will create a graph which incluses Charging current :)

But yeah.... Mostly works! Charging 60% in 45 Minutes.

Graph:

Values:

Even tough the BatteryHeat drops after 65% it still charges extremly fast until 80% ~ 85%

Is that healthy for our battery? i don't know... i've written wee bit about that here
