Any easy way to log frequencies ? I'm going to see how cyanogen behaves.

HereIam could have some problem with cyanogen nightly

EDIT: I'm also familiarizing with Power Tutor, finally, having some spare time. To be honest, at first the low ratings in the market and the fact that it wanted to access my gps position made me suspicious, but I see the rating are from Hero users (FC's) and probably the gps position is for understanding when I use it, not where I am.

First impression is that it's a very nice tool, I hope it's reliable because it gives a **%($)-lot of information. My first surprise was to see that CPU actually drains quite a bit. I was under the impression that given the fact that today you can have hexacores with 10x power on desktops, mobile phones CPUs could have so good power efficiency, because of the scaling down, that they barely would impact battery life. But, hell, we are talking about 1Ghz here, that reminded me ...
[Desire General] kmetek:
Seems it drains less battery, from morning which was around 72% at 8am, now at 2:30 it's 65% :)))

ME HAPPY and not even on FROYO 2.2 :P

While using this excellent tool (power tutor) and trying to kill my battery by playing robo-defence on permament fast-forward, I've noticed that:

- yes, playing games uses tons of cpu

- the reported power consumption for the audio section is massive, but the best part is that I had media volume off ! Is this a missed optimization by the program, or standard behaviour ?

- power tutor drains quite a bit of battery running in the background ? Am I mistaken ? I really think I am, but asking confirmation.
[Desire General] th3:
Re PowerTutor:

- I don't (and didn't) look at market ratings, so I've no idea. Basically, there is no consumption monitoring power tool that comes close. Nothing has the internal data (tech docs) nor Google support to access each hardwares power figures on this device nor does anything else base feedback on actual device measurements as this. I mean, actually running this tool and calibrating the power draw figures it gives compared to the physically measured values of each hardware. Just wait till you see the fixed version that can take each pixels power state and give us info on the real-time OLED power draw.

- It's developed for stock ROMs mainly and the custom ones have too many niggles with such software. I wouldn't be surprised if it just causes FCs. I can only give feedback on that to the dev if you let me know. It is being designed to be ran as your one-stop power profiling tool that has accuracy. It does have many shortcomings yet though.

- Yes, it used to cause high CPU usage in the past so maybe that is why the ratings are not good and/or uninformed users who don't really know what it's about and what it's doing. Currently, if you switch to live view the CPU usage will be 10-25% but in the background profiling, the CPU usage should be 3-10% maximum. It uses the same amount of CPU as System Panel app when you switch to monitoring/profiling. Devs are working to drop the CPU usage lower in the next releases.

- It doesn't necessarily require GPS data but power stats it sends back unless you opt out of that, which you can.

- Even if the audio volume is off, the audio codec/amp subsystem must be running to decode the info so it will be under the required load.

- There is a widget on this idea in development.

- If you are running the profiler, in the notification menu, it will give you the total power draw of the device (based on actual measurements, and then software feedback of voltage and current).

- If you save the log after a profile, you have much more fine grained data to asses. That includes CPU frequency and power at each interval. The "System" app can also give frequency figures after a profile.
[Desire General] andycted:
yeah, don't worry, I see it's a good program, can use some improvements, but definitely one step ahead of others.

Does the cpu reading spike constantly through the maximum value in your case too ?

Now, tell me I'm wrong, but for the love of milk, I always seem to draw more current while streaming music through wifi, than with 3G/HSDPA, 600 vs 700 mW, even with the phone 10 cm from the router....does it make sense ?

The audio drain also seem to be constant most of the times when playing anything...
[Desire General] andycted:
I'm on cyanogen nightly. With or without setcpu installed, I've usually seen it at 245Mhz when idle, both in the log and in systempanel (where it actually reached only 260Mhz because it was showing the graph in real time)

[Desire General] andycted:
Nice paper ! I'm low on battery trying to test a bug ridden htc rom for battery drain (massive screen drain with auto brightness)- I'll read better and comment later, but regarding those numbers codes I remember 1005 as spiking with youtube and audio playback, hehe...

Good job !
[Desire General] andycted:
I've repeated the 3g vs wifi test with youtube, the results are the same, although while wifi was going from 0 to 700 and back very often, I.e.switching power on and off and staying half the time off, 3g was almost always on, between 600 and 400.

Xiialive performs the same as with aosp roms in this htc rom, constant 700 and 600 for each connection.

It surprises me however, that power for the wifi doesn't scale at all according to quality of the signal and workload. It just turns itself on and off.

Could this be down to the reading by power tutor ?
[Desire General] andycted:
I really wouldn't think so, as they are probably manufactured in the same way, by the same company.

Sorry, I missed the point about cpu drain, I will repeat the test as soon as I get rid of this mess of a rom.

Well that says that in some instances, 3G is a bit more battery efficient than WiFi, right ?

It would be interesting to know if without emitting sound it's the same (with speaker on), like at those times when you pausing robo-defence and you hit the volume buttons, it changes media volume.

I would really think yes.

I wonder why those are displayed as numbers.

While you are crunching hard numbers, I'm doing the fun stuff, pratically checking every rom out there to see if values are somehow different. They are absolutely not.

The only real, consistent battery efficient change, is the lower autobrightness in AOSP roms, in conjunction with screen colour/darkness. CPU and network load are absolutely the same. Battery life is the same, if I take out auto brightness on HTC Sense roms.

EDIT: changing kernel has basically no impact in my experience, at least for the average Mhz and the ramping up. I used to have SetCpu installed with some profiles to lower Mhz when idle or in some other instances. While testing Mhz on AOSP/cyanogen vs HTC Sense roms, with and without SetCPU, I couldn't really see a lot of space for improvements in lowering the Mhz at idle. Of course SetCPU can still be useful if you just want to underclock or overclock your phone, with or without profiles.

Total system battery drain while viewing a video on Youtube with max brightness:

on wifi: around 1400 mW

on 3G: around 1700mW

3G was very choppy, as I had HD video there too.

I can't see wifi usage for youtube, while there is the graph for 3G
[Desire General] th3:
Same here. It was freezing and stuttering. Assuming you have at least 2Mbps with WiFi, if you check the WiFi network usage and power, initially it spikes and then goes back to idle pretty quickly. Efficiency is power x time hence why it is said to be more efficient with higher loads since it draws power for a lot less time.

You mean WiFi power usage in the PT app shows nothing in that period? If so, that's showing up on mine as usual.

I had no phone for a while since I messed up the colours on it and the screen would be on but just black :P

[Desire General] th3:
Yep.

Not on the N1 it doesn't. Power differences with speakerphone and headset on compared to the norm is one aspect I asked about and the values they measured were fixed as long as an audio signal has to be processed.

It was similar to WiFi - unlike cell network, it did not vary in power consumption depending on signal strength, which is the same as what the studies I linked earlier found.

Do you mean why they don't show as process names in explorers and so forth?

Many third party apps appear in the same manner, such as Handcent.

That's interesting. So you get absolutely no changes to functionality or stability on so many ROM changes?

The prime reason I don't like to move ROMs is because I do. Case in point: this is my second hard reset/wipe all on the OD ROM and it still has too many basic errors in functionality and stability. It has so many of the problems people complained about when FroYo came out that we didn't have on the HTC version. Like the screen being far less responsive. Like the compass, keyboard, trackpad and touchscreen suddenly dying for minutes randomly. Or how whilst typing the screen keeps fast-scrolling upwards. Like how the cell icon shows 2-4 bars when I actually have no reception. Like how the market is bare slow and apps rarely download and install from the market. Or how voice search doesn't even install. Like why I can't get idle power figures as this ROM never does idle with the " Android system" process using 2-15% CPU regularly. That's where the 40-60% under battery usage info comes from. Idle draw should be ~110mA whereas this ROM predominately keeps it at 128-131mA. It makes running controlled tests very difficult. The list goes on and on. This amount of FCs with apps and problems is far above my threshold for acceptability.

Thanks for the tests and feedback. Useful to know.

I learned to deal with the different quirks of aosp home cooked roms for the Love of funny customization, people effort and open source community, but I agree that as soon as I flash an htc rom, I can't go back. The level of polish added by htc and a whole bunch of bugs less, makes a hell of a difference.

Anyway, about mini bugs and glitches, there is a world of difference between roms, especially from aosp vs htc based. But for battery usage, there is basically no difference.

I gave up od because it provides the same exact battery life as others, while including the same cyanogen bugs, but with less functionality.

Battery life with with both roms was ok, but apparently someone had problems with the oj stuck and draining battery.
[Desire General] th3:
After 2 complete battery calibration cycles and stat wipes, the "Android System" power usage problem seems to have showed up with more details. Priorly, it wouldn't show up anywhere else. Whenever the display is on (for the complete duration even when there's no touch), it looks like a sensor is draining the battery by causing 5-15% CPU usage consistently:

http://bit.ly/a6LCB0

http://bit.ly/b5wnez

http://bit.ly/aDLfBd

Now which one? That is the question... This is on OD 3.1.0.

[Desire General] bemymonkey:
To be honest, I think this is more of HTC's borked power usage statistics coming to light. Note that in AOSP ROMs (like OD <=3.0.5), not only is Display >50%, but Android System is also <15% (always).
[Desire General] andycted:
It could well be the case, I'm at the beach, blinding sunshine, max brightness all the time, and it's only showing 18% for display. Since I've had the display on 90% of the time, battery usage should be at least 500mA in every instant

Hi Everyone,

I rooted my DX, and before I really knew what I was doing with Titanium Backup I uninstalled Blockbuster rather than freeze it. Now, I know I could just reinstall it from the market, but that won't help me when the update is looking to make sure the stock apps are installed. Besides, I don't want it anyway, I just meant to freeze it rather than uninstall. Is there a way to restore it as a system app?

Thanks,

Mike

Yeah google "droid x system dump" and "how to restore system apps on droid x". I'm not sure what forum I saw them on, maybe here. It's pretty simple with ADB.

[Nexus One Themes and Apps] denimjunkie82:
I think this would be pretty cool. If the phone is charging, then the bottom 4 haptic buttons would stay lit. Then they would turn off once the charge is at 90% or 100%.

It would be a good indicator for those of us who use CPUStatusLED. Plus I think it would look pretty pimp.

For those who think it would be unnecessarily bright when charging at night, then maybe make this option toggle-able.

Anyone know if it is possible, and if so would it be easy? I can attempt it myself if someone can help guide me, but I have very little knowledge of how something like this works. Just PM me if you're interesting in sharing your knowledge.

Thanks
[Nexus One Themes and Apps] Deathwish238:
Ooh that would be cool. Or maybe make them pulse periodically(configurable of course).
[Nexus One Themes and Apps] denimjunkie82:
Well now that you mention pulsing, I got another idea. It would really cool if the buttons can light up in succession, like a LED scroll. Since it seems like the backlights naturally pulse on and off (rather than a quick blink) I think a scrolling pulse would look awesome. Maybe keep each series of pulses a good 5 seconds apart or more so it doesnt look too crazy. Then once the phone is fully charged, the backlights would stay on.

It would definitely make iphone owners jealous too.

Hi everybody. My first post :). Ive been reading lots of threads for a couple of weeks. I decided to make an account to get some help with topics and also help others out where I can :).

Im looking to buy myself a Google Nexus One. However theres a few things which im not sure on about the screen.

1. How badly do fingerprints show up? Is it really noticeable? I currently have an iphone 3gs which shows finger prints, but its not that bad and cant see them when the phone is on.

2. How "Good/Bad" is the Nexus One screen? By this I mean from videos I have watched on youtube the nexus one screen always looks darker and other screens look so much brighter and just more inviting. How noticeable is it?

Thanks for all the help. If my questions have been answered before (recently) please post the link of that thread :)
[Nexus One Q&A, Help & Troubleshooting] mtl171:
