[EVO 4G Q&A, Help & Troubleshooting] sk63:
Well if you're NAND unlocked then no, you're still stuck with a PRI of 1.34. I can't remember if that was lower than original release PRI or not so going to pre-ota 2.1 may or may not hide your tracks.
[EVO 4G Q&A, Help & Troubleshooting] DanBergundy:

How can I determine which brand of screen I have on my phone (novatel/epson)? Is there an adb code to list all the hardware?

My hardware version is 3 but my understanding is not all version 3s have the same screen. Besides how they look side by side which is better as far as fps and such? can you flash kernals to increase performance for both screens?

[EVO 4G Q&A, Help & Troubleshooting] DanBergundy:
Either scroll around until you see one off the two screen names or press menu and email it to yourself, search all the text on your computer.
[EVO 4G Q&A, Help & Troubleshooting] mrono:
easier way, put the power control widget on the screen and hit the screen brightness button. if it fades then it's nova, if it just snaps between brightnesses it's epson
[EVO 4G Q&A, Help & Troubleshooting] fachadick:
The easiest way to see what screen you have is to simply cycle through the brightness presets on the power control widget. If the brightness changes instantly, then you have an Epson screen. If it fades to each brightness level, then you have a novatel screen.

[EVO 4G Q&A, Help & Troubleshooting] jd9900:
Easiest way I know of to determine your screen type....adjust the brightness setting.if your screen fades from bright to dim it is a nova screen. If your screen instantly dims it is an epson screen .

[EVO 4G Q&A, Help & Troubleshooting] JavaIV:
Actually, IMHO the easiest way to tell what screen you have is to use ADB. commands would be as follows:

adb shell
dmesg |grep -i epson
dmesg |grep -i nova

One of those dmesg commands will return a result and one wont...done and done.

Great initiative. :D Just need more people to help report their battery life, as there seem to be quite some difference among some peeps.
[Desire General] Bouncer5:
Yea I know, I need to find some other tests, Any suggestions?
[Desire General] zarg2:
Not a suggestion, but a question : When you go to the *#*#4636#*#* menu, what is your battery voltage ?

Many report 4200 mV after 2.2 update, but I only get 3890. I know it's not much, but still...
[Desire General] martintzvetomirov:
Has by any chance anyone made such test under Eclair?

Btw I've noticed that if you use task killer you can save battery. Apparently there are some apps that even when closed keep eating battery. But I really have no proof of it (and have no time to conduct tests). Maybe someone can help me?

And I also suspect that Chrome to Phone eats battery if you don't press "disconnect" even when you don't have any Internet connection enabled. But that's another thing I can't prove.
[Desire General] andycted:
brief tests - unconclusive, eh

I never thought that battery percentage is accurate enough to perform these kind of test, also didn't have much time to do it (so basically % never changed in 15 minutes timespans). Anyway:

* started at 21%

- Everything off (screen too)

- gmail push on

- good (3-4 bars) mobile connection on 3G

- no 3G data connection

- Wifi on - sleep policy -> always on

- Wifi router is about 1m far away from phone

15 minutes later

= still 21%

next --------

* started at 20%

- same as before but

- wifi off

- 3G data connection on - mobile data connection NOT always on

15 minutes later (19.43)

= still 20%

next --------

* started at 19%

- same as before but

- 3G data connection on - mobile data connection always on

- gmail push received a short email while testing

- hotmail checked mail as scheduled and downloaded 6 short emails

15 minutes later

= still 19%

Tests were started as soon as % showed the reported number.

By night, on airplane mode, it loses about 2% in 8 hours.

Can't really complain. By the way I'm still searching for a tool like WinMo BatLog. Anybody knows if it's feasable on android ?
[Desire General] martintzvetomirov:
I've been searching the market for a while but I couldn't find a tool that shows the power drain in Amps :(
[Desire General] andycted:
Brightness

Airplane mode - Completely white screen

* Full brightness:

started at 17%

after 2 minutes = 16%

(brief pause to check, then back on white screen)

after 1 more minute = still 16%

(brief pause to check)

after 1 more minute = 15%

(brief pause to check)

after 1 more minute = 15%

Lost about 2.5% in 5 minutes

* Minimum brightness:

started at 13% (didn't wait for full step, probably was already close to 12%)

after 2 minutes = 12%

(brief pause to check, then back on white screen)

after 1 more minute = still 12%

(brief pause to check)

after 1 more minute = still 12%

(brief pause to check)

after 1 more minute = 11%

Lost about 1.5% in 5 minutes

(kept going with low brightness)

after two more minutes = still 11%

after one more minute = still 11%

after one more minute = still 11%

after one more minute = still 11%

Apparently lost less than 1% in 5 minutes

Probably the % is not very accurate here anyway, or maybe at the beginning of low brightness test was still hot from the previous high brightness one.

after one more minute = 10%

time to plug it in, I'd say...
[Desire General] andycted:
I've seen somewhere someone (eh) reporting that in /proc/somewhere there is a setting that can be read to do it. That is where my knowledge stops.
[Desire General] andycted:
I have one battery at 3742 mV, however it's at 13% and charging.

The other battery, which is almost full and not charging, shows 4153 mV.

Don't know if it's affected by charging state.
[Desire General] RaptorRVL:
Yep, the more juice you put in the battery the higher the voltage. So a more fully charged battery will have a higher voltage than a lower charged battery.

It goes from like 3.3v to 4.2v.
[Desire General] andycted:
Erm, yes I've explained myself not very well... I meant that I didn't know if the fact that one was charging and the other not could impact the reading. I wanted to provide the approximate range of usage, since, if I'm not mistaken, the phone turns off when it reads 3.3v ?

EDIT: also on the same note, I think if I remember correctly, I've read that the % read is sometimes 'skewed' depending on how full the battery is. Like 1% battery at 100% lasts (for example) longer than at 50%. Am I awfully mistaken ?
[Desire General] RaptorRVL:
Yeah, shutdown is usually around 3.2 or 3.3. It depends on the manufacturer. I think the batteries get damaged below 3.0v. Protection usually kicks in around 2.7v - 3.0v.

Not 100% sure, because I always mix up LiPo's and Li-Ion batteries :D

While charging the voltage will be a bit higher, and when you unplug it will go down a little bit.

Yeah indeed. The voltage drops much faster when 100% charged than 60%-70%. Also the reason why there seem to be so many issues with the wrong percentages shown :D.

As shown here: http://www.ibt-power.com/Battery_packs/Li_Ion/Li_Ion_DiscGph.JPG

Just some random graph found via google :)
[Desire General] Bouncer5:
Screen is set to the lowest setting using the powerbar, Also the screen was off at the time of doing the test, i.e if it was in your pocket.

During the screen test with the image, it was set to as bright as the power bar will allow
[Desire General] andycted:
Right, so it's pointless to compare battery drain % at full level and at 1/4, for example. I've also read somewhere that battery temperature influences the reading, as well as reducing the efficiency of the battery itself.
[Desire General] Bouncer5:
If you really want ill get back and do it with the *#*#4636#*#* and give you 4 digit number from there :rolleyes:

Wifi streaming + screen on

Tested music streaming with xiia

* first run with WiFi

- most stuff off, same as previous tests

- music channel was accujazz

- music through the speaker, half volume

- WiFi on

- Airplane mode on

- Screen on (forgot the timeout off)

Battery went from 92% to 88% in 15 minutes (4%)

* second run with 3G

- same as above

- no airplane mode

- 3G in place of WiFi

Battery went from 68% to 62% in 15 minutes (6%)

I've repeated the test and still it seemed that 3G consumed a bit more battery than WiFi (5% vs 4%), but this might be also due to the fact that the first test had no mobile connection on.

They were suggesting it in cyanogen, if it was possible to do something similar to the render colours, which however I think it's very different.

However, I'd really really really - really - would like to know if there is a way. And drop tapatalk and about every google tool that has a mobile version

[Desire General] bemymonkey:
I've entered a bug report on the Android issues tracker, concerning the borked statistics on the Desire and my concerns that other Android devices could be showing faulty battery use statistics as well.

If you have suggestions, please feel free to add them in the comments - if not, I'd love to ask you to show your support by "starring" the issue.

http://code.google.com/p/android/issues/detail?id=10537

I will be sending HTC tech support a similar bug report later today.
[Desire General] andycted:
That's another bug from AOSP builds hehe. That and others irked me so much, I've switched again back to HTC roms, as I also can't bear missing some core functionalities in the camera, gallery and such.

Anyway, regarding battery usage, what I've noticed -but probably needs to be measured- is that on OD and CyanogenMod the kernel showed on SetCPU scaled down a tad more than with HTC roms. Additionally on HTC roms it had a tendency to go from 245 to 998 without middle steps, like an on/off feature. But ! Then I opened System Panel by chance, and noticed that there the Mhz was reported more granular (on HTC rom) and that probably SetCPU had some trouble interpreting some values.

I can still think that AOSP kernels are tweaked a bit to scaled down more aggressively, but not so much as to show a significant battery saving, or to show on tests. This is purely from every day usage experience, because I'm about lost on how to test it reliably

EDIT: I've tested the battery calibration method that appeared few days ago in Developement (they should split Development in 'Real Dev' and 'Wrong Posts'). I also tried to jump around the phone waving with a big stick and mumbling voodoo, but apparently it works. It seems to circumvent an aggressive cap on maximum charge capacity, even though if I remember correctly, you are not advised to reach 100% (or 0%, which is worse) all the time, on li-ion batteries.

how did you manage to get only 3 processes

Uploaded with ImageShack.us

is it normal that you have 70% ?
[Desire General] andycted:
At the risk of saying the obvious, did you notice that display stats on power tutor don't vary with dark vs light backgrounds, as in the widget?

One more thing:

400mA for the extra white display...

400mA x. 3.7V = 1440mW

What am I doing wrong? Isn't that too high?
[Desire General] bemymonkey:
That's actually one of the reasons I've been relatively untrusting of Power Tutor - it doesn't really seem to do much other than generate theoretical stats based on the time components were on.

Why too high? Sounds right on the money, IMO... th3 got 450+mA.
[Desire General] andycted:
Because Power Tutor has max 900mW ... which could be an average estimate of that level of brightness with a mid-light display.

Yeah, I've been using power tutor for a while, I understand it's a work in progress and appreciate the effort from the developer, but I wish he would mention where he gets accurate values more directly (as probably in the cpu), where it's a bit of an estimate (wifi and 3G) and where it's total guesswork (display).

On the subject of the mV difference when 'calibrating' the battery, it occurred to me that the value read in spare parts is usually affected by the battery state. I unplugged the phone when it was a decent value, then after a couple of minutes it was higher. Magical phone ! Recharges through wifi (which, you know, could actually happen in the near future)
[Desire General] bemymonkey:
When the load on the battery is reduced dramatically, the voltage can rise again. It's not magic :p

That's the problem with using the voltage to tell you how much is left in the battery... but it works okay (hence why that's the way every manufacture does it)... :)
[Desire General] andycted:
I insist my phone is better than yours, it's special, as it includes this:

http://gizmodo.com/5444850/rca-airnergy-charges-gadgets-with-nothing-but-wifi-signals

It also prints money, creates an island and transforms into a jet to fly you there, grants three wishes and it's indestructable. Oh wait ! That was the Evo. (if you've seen the video)

The only good use I'm getting out of power tutor is to monitor which application drains more juice while 'doing nothing' and it's quite useful at that. For real battery drain of - for example - wifi vs 3G, or display, I guess it really can't be trusted (yet ?).

In that regard i find the Gallery3D and Flikie Wallpapers to activate themselves randomly to either rebuild the cache or open a network connection and use incredible amounts of CPU. I hate Gallery3D and that alone could make me steer away from AOSP roms. Now I will also uninstall Flikie

EDIT: (oh, by the way, that's a semi-scam, if you haven't made your math already)
[Desire General] th3:
Kmetek: By doing nothing with it :P

Andycted: The DVFS on Snapdragon is extremely efficient and fluctuates MHz based on load very dynamically, rather than to a few fixed P-states. So the System Panel values would be more correct of the actual frequency. OSMonitor is another app that can't log granular and intermediate frequencies.

PT doesn't yet support the Desire display readings - that's why I suggested waiting for the update earlier :)

The updated version does and the values should differ based on the displayed image as expected. It should be rolling out sometime next week. So ignore the display power value for now.

Have you seen PTs CPU/WiFi/3G/Display power use per app section?

(Gallery and Camera is also a huge dislike of mine on the Google ROMs)

The actual calcs done for the power usage of components by Androids built-in monitor are very simplistic and wrong for an OLED (they don't take into account displayed image. at all). Here they are: http://www.netmite.com/android/mydr...oid/settings/fuelgauge/PowerUsageSummary.java

That's the Android source code for the battery usage section. The relevant screen power consumed section is down by the function addScreenUsage.

Thanks to the PT dev for sharing.

Alright, so I guess it can be trusted, but all the same sometimes it looks a bit off for 3g and wifi.

Do you actually think setcpu is useful in reducing battery usage with "screen off", low mhz, profile ?
