Battery Problem! Doesn't last long...

My battery is really not lasting that long on this Diamond. Any thoughts/suggestions would greatly appreciated. Someone recommended a regedit in regards to auto internet disconnect. If someone can point me in the right direction, that would be great! Thanks!

Welcome to the club

I had the same issue with mine when i changed the ROM and RADIO, So Im using a cooked Rom(Energy 3.0) and a test RADIO from at&t and I have to say it improved considerably. I would change the radio and play a bit with the power management section in Advanced Configuration (awesome app). (plus the usual "lower your brightness, dont stay connected when youre not using it, turn off ur screen every now and then" protocol)
Dont look at your battery meter so much and youll be fine. Best of luck

Improving battery life

Hi @all!
At the moment android kernel development for X1 is stalling, partly because most important things are working, partly because it is getting warm outside The biggest show-stopper for replacing WiMo is battery life. Everything under a day is not very usefull. This thread is dedicated to improve that.
What we know?
The X1-battery has a capacity of 1500mAh. My current WiMo can live with that energy for nearly four days with active data connection for emails, but without phonecalls. That is good.
To use android for every day it should last at least for one day. That means, the system should not use more than 62,5mA during standby. Atm it uses around 200mA, so battery is empty in under eight hours
What to do?
At first we have to know, what part(s) of the system are eating up the battery. "Know your enemy!" Then we can try to improve it.
How to do it?
Well, that is the interesting part. There is no "right way" to get this done. We need creativity. One way may be to activate and deactivate parts of the system and see how the energy usage changes. Or change the system clock.
With drlucky's great battery-driver-port we can see the current used by the system. It is as accurate as the WiMo-readings because it reads out the same hardware-chip for battery-monitoring. This can be used to corner the culprit.
Sadly android battery info does not contain a current-value. So the only way is to read out the kernel-log with dmesg-command. Maybe someone can create an app for this?
To get started, read this post. And please use THIS kernel image for battery tests, as it shows correct miliamp-values. That way we can compare the results. I am out of ideas for now. Here are some keywords to think about:
-How does WiMo save energy?
-How to easy access the current value in android?
-What programs are good for battery monitoring in WiMo/Android?
-What is eating up battery in android?
-How does power management works in linux/android?
-wakelocks

Great to see you back,
i'm not a dev but i guess one of the problems could be given by the 'speaker fix', that causes the speaker to be always enabled?
Keep up the good work and thanks for everything you've made possible so far.

best drivers?cpu/hardware scaling?
i'm not a dev.... only a linux/ubuntu user...
but all the android devices have not a great capacity to save energy...

hope you can do something well =)

Great job
It's good to see people working on this project
i think the main reason for battery discharging is that the OS can not turn off the chipsets that it's not using...so they stay always on and consume energy
although i'm not sure about that but may be that's the case
All the best

i think, some drivers have a problems? it's impossible the phone/battery in few minutes are incredible hot... and this with: gps/off do not work, wi-fi/off.

An idea: We can look first and foremost in /proc/wakelocks to see if anything is holding locks to prevent the system going to idle.
If anything holds a wakelock, the phone will be running full bore all the time.
My phone is sick at the moment so maybe someone can check this out.

Thanks, i just learned something new
Here is some more info on wakelocks.

I'm sorry, I'm not a dev. But, does the battery last few days for other htc phones with Android ported?
If not, maybe it's the way Android works when it's running from Haret. Maybe a ROM will make some things work... Who knows?
I can't wait to see Android fully functional on my X1. I really like Android, and with looks of X1, it will be the best.
Cheers!

Windows Mobile saving batter everytime when can. Things what using batter in last build of kernel for X1 and drying batter in some hours is:
-SPEAKER IS TURNED ON 24/7
-PHONE "LISTEN" EVERY KEY ON PHONE (windows mobile just "listen" and refreshing POWER BUTTON and over that button WinMobile backing everything in life)
-PROCESOR CLOCK IS 24/7 ON MAXIMUM
-AND IF I SEE GOOD CAMERA RECIEVING POWER FROM BATTERY 24/7 BUT NOT WORK
So lets extreme developing start

In terms of speaker always on issue, the problem is that we are enabling it in the first place...
Code:
void enable_speaker(void) {
if(machine_is_htcblackstone()) {
gpio_set_value(57,1);
} else if(machine_is_htckovsky()) {
printk(KERN_INFO "DBG: enabling kovsky speaker...\n");
gpio_configure(0x41, GPIOF_DRIVE_OUTPUT | GPIOF_OUTPUT_HIGH);
gpio_set_value(0x41, 1);
// now wait for GPIO 0x41=1
} else if(machine_is_htcrhodium()) {
//Needs userland fix
if(force_rhod_speaker)
enable_speaker_rhod();
else
disable_speaker_rhod();
}
}
Looking through the rhod code it seems there is an option to force rhod's speaker enabling when switching snd device to speaker - Which is disabled by default because android always leaves it on...
Perhaps we should look at something similar?

Code:
void enable_speaker(void) {
if(machine_is_htcblackstone()) {
gpio_set_value(57,1);
} else if(machine_is_htckovsky()) {
if(force_kovsk_speaker){
printk(KERN_INFO "DBG: enabling kovsky speaker...\n");
gpio_configure(65, GPIOF_DRIVE_OUTPUT |GPIOF_OUTPUT_HIGH);
gpio_set_value(65, 1);
// now wait for GPIO 65=1
}
else{
printk(KERN_INFO "DBG: disabling kovsky speaker...\n");
gpio_configure(65, GPIOF_DRIVE_OUTPUT |GPIOF_OUTPUT_LOW);
gpio_set_value(65, 1);
// now wait for GPIO 65=1 switched to decimal, ok?
}
} else if(machine_is_htcrhodium()) {
//Needs userland fix
if(force_rhod_speaker)
enable_speaker_rhod();
else
disable_speaker_rhod();
}
}
or is this not possible like this?
with force_kovs_speaker made

@Reversedhex
^Yes, exactly.
I am working next 5 days...let us know if you have any luck...
BTW; The code is from external.c

Great
Next thing !!!
-SPEAKER SOUND IS ON 40% ON MAXIMUM and NO CHANGES TO 100% IN LOUDNES, SO SOFTWARE PUSHING TO MUCH ENERGY TO SPEAKER
-OR SECOUND THEORY IS: SPEAKER IS ON 100% 24/7 and cant CONTROL AMOUNT OF ENERGY...
(this can't help a lot but everything is good )

Do you have it enabled in the kernel? You need CONFIG_WAKELOCK_STAT enabled to see it in /proc/wakelocks

Thanks! This option is not set in .config, i will try that!

[Q] 4 random questions...

I'm looking for a new phone, so if someone could answer these questions I would really appreciate it.
1. Is it possible to change the font size of the text on this phone for menus, sms, web browsing, apps etc.. everything in general?
2. Just something I heard not sure if it's true but, does the super AMOLED really use 2x the power for white color backgrounds than for ANY other color? That would be really bad for web browsing which I intend to use quite a lot.
3. How much does the battery last with only web browsing over wifi and music player in the background?
4. Any tips about Galaxy S or things you don't like about it? (whatever comes to your mind really)
thanks

Well , at least i got no problems with the baterry life at all , i can use it all day with music on and playibg games browsing etc... Also the super amoled is simply amazing. Overall i really like the phone at all points , the only disadvantages of it are the lag problem wich can easily be fixed and hopefully by samsung in the nearby future. Also its knowb that the gps is not working well but i didnt try this yet

be more specific.
the GPS works
the problem people are complaining about is that the GPS is not accurate enough for some people

Do you mean 'How long does it last with just some regular web browsing and music playing ?' or do you mean 'How long can I browse the net for before I kill the battery ?'
The first one: the battery will last you just fine to look up a few things here and there and generally be a daily driver.
The second one: A lot less than you think. You will get maybe 3ish hours with the screen lit between charges. The level of brightness and other things on the phone can change this, but seriously, don't be thinking about spending a great deal of time with the screen active unless you have some source of power.
Either way, this is not a problem with the SGS, ALL phones with big screens regardless of os or manufacturer have problems with battery life, at least in the sense that they never last as much as you'd want to.
As for any other tips and tricks:
Check your GPS when you get it out of the box, then apply one of the fixes if need-be. Some people find that out of the box, they either can't get a lock, or there is a lack of accuracy. I got the first problem, but the fix works fine and now I can satnav with the best of them. The accuracy isn't perfect, but good enough. Before I have been shown as driving 10 yards off the road in a field but it corrected within 30 seconds and its not like it became unusable. I have never had a problem with using the navigation. It has ALWAYS got me where I want to be.
Secondly, for gods sake use a lagfix, even if you don't get lag. As you put more apps on and fill the memory up more, you'll eventually get some slow down, so you may as well nip it in the bud.
If you are going to buy a droid device in the near future, the galaxy is the phone to buy. Get one, you will NOT be disappointed.

Totally agree , even though still hoping that samsung will bring us a bugless froyo very soon.

Could someone answer the first question please?
Here I thought of another one... Does the alarm clock work with the phone closed?

Fonts can be changed depending if app supports it. I use lcd density changer. And of cause alarm works but do you mean when phone is totaly powered off? No idea

Not sure how to interpret "phone closed". Screen off, yes it works. Phone in a case, yes it works. Phone off, no it doesnt work. If I've missed what you've meant please clarify.

My bad, I meant with phone OFF.
Well.. that's actually quite sad. Is it possible to make it work with an app or by rooting the phone?

Touch Diamond Battery Epic Fail

Hello all =D
I'm despaired by seeing people running nice Android on there Touch Diamond...
I'm explaining to you :
I tryed a lot of android rom (2.x) from XDA, CONNECT-UTB & NeoPeek...
The result is always the same : BATTERY DRAIN --'
I tryed many kernel, modules etc,etc on glemsom.users.anapnea.net/android2/htc-msm-linux/
I don't know what to do ... WM makes me beeing crazy, like all of Microsoft products...
I really need your help...

You should go on ebay and buy a new battery
pretty cheap

For me, its seems coming from android drivers, because WM runs for 3days without plugging AC Power ...

Oh haha, I have the same problem, your not the only one. But in the android porting of the DIAM, this has been known as a issue, and this point everything is being done. The battery is just PART of a list of bugs and issues.
What you can do to limit battery drain
1] Lower settings on android -Screen brightness, -Use Data when needed otherwise keep it off, also with internet.
2]I have gone through many kernels and it all of them vary, but ill let you know what kernel i have [because its ok with the battery]
3]Be patient because this is a project in the making so fixes will come as they are found [camera, video etc]
ALL this is mentioned through the massive thread [I would hate to read it all]
http://forum.xda-developers.com/showthread.php?t=711692
stay tune

Adjust your backlight (for me, the maximum brightness is too strong - I'm photophobic- so I use the backlight on its 30~40%), or turn off connections like GPS, BT or Wi-Fi, just turn on when it's necessary...
It'll save some batt...
If the problem continues, grab a new batt on ebay...

I did it, it seems to be better, after 12h with a low utilization, the battery is at 60%.
But it's long to wait for a good release x)

[Q] Questions about ICS (B4 at now)

General questions about ICS working on our Streaks.
My first: i cant go to the fly mode whithout a crash rebooting. How we can solve it?
--------------------------------------------------------------------------------
Quick review:
1. Fly mode brings into crash -> Dont worry! Simply restart and dont power off this mode, it saves your battery a little
2. No 2g/3g radios -> We are sorry
3. I dont need useless SMS/MMS stuff -> You can uninstall it, but dont uninstall the phone.apk and telephony.apk
4. I have flickering screen at low brightness value -> [Only one way is to change it to a different level] UPDATE: use ScreenDim
5. Floating charge of battery -> ?
6. Games dont work! -> tegra2 drivers not exists

Don't do it.

Yeah, all works fine! , better than HC ... more battery life 300%, free ram, CM9 !! ... iu can install DSP manager ...
Dont work:
... only cam, video cam, phone app, 3g and 4g,no sim detect,fly mode crash, dock station ramdoly crash.

No radios besides wifi/bluetooth work.
And voice calls are still in deep discussion if its possible.

If you restart after (crashed) turning on fly mode, you should stay in it. And you can save some battery power (~7 - 10%, GO power master said, because some telephone modules and mobile internet works in background, inspite of the fact that you dont have sim card). So you can use wifi and bluetooth too (in fly mode).
Also, my Streak charged in one hour and 30 minutes from absolute zero to 100%. Is it normal? Why it is so fast?
Discharging is rather long - about 32.5 hours!
One more question: can i uninstall some system apps such as sms/mms, calls and other useless?

Go ahead and uninstall the SMS/MMS stuff, but for now don't uninstall the phone.apk and telephony.apk, I've actually had worse device performance and more crashes because of it.

New question! How can i get rid from flickering screen at 20-40 brightness value? AnTuTu CPU Master cant use GPU control because it doesnt supported for our device at now. Can we change a kernel to more tweakable maybe?

Because we do not have a 2.6.39 kernel nor a 3.0.x kernel from Dell, we have done the best we can in tweaking the 2.6.36 kernel to work with ICS.
How about not having it at the brightness level? Change it to a different level.

Not long ago i installed BatteryMix program and discover, that my battery have floating charge - sometimes when i power off the screen (cpu frequency and battery temperature is falling), the charge is raising for 2 - 3%! Is it safe?

Guys, i cant play games on B4 at all! I installed many popular games, but they dont run. Even TrialX2, that i played on stock and HS 3.2, doesnt work! I tried Chainfire, but it doesnt help. What is the reason?

Games dont work because of tegra2 drivers, that this rom doesnt have. I returned to HC for this time

I am pretty sure that posting questions that had already been asked fell under this... but then again n00bs never use the search bar

Nocturnal_50, this thread is a public talk with Giveen for me, mostly. I think its a good way to posting my questions in one thread. So, give me the links or describe the answer, if you can. Nobody needs your useless comments about nothing

Look over this, people continually ask about it, giveen has told me he will no longer be creating ROMs for the Streak 7 and that DJ_steve is the only hope for ICS_b5 unless someone new steps into the game.

Ok, maybe. So where is some faq about it? We always should read 32 pages of text?

if you are taking the TLDR approach then try from about page 26 onward

There is one thread for all versions, not only for b4, maybe - i dont know, which problem exactly described for b4 (maybe for b2 or b1 or b0.0001). Second reason - this thread is very dirty (its my opinion). Helps him dell or not, have they problems in code or not have, do they need money or bear - i dont care (as usual user). I dont want to read all of this! We need different threads for dev and for users with their questions and faq - it is normal practice for many device branches on xda. But we havent normal thread for rom, normal faq, normal question thread - and you say that i should read all garbaged (for me in this situation) text.
