Hey,

i also used your tips to improve battery life but i have a problem that i dont understand...

in standby my phone uses about 5-7ma thats fine... But i just get it if i press one of the hardware button on the phone while booting android (maybe you can add this as tipp aswell i can remind me on reading this somewhere in the forum... :confused: :D) if i dont do that i get about ~50ma in stand by... now the problem... if i call someone the standby usage raises to ~50ma and i dont have a clue why... i can use the phone how i want and nothing changes but if i call someone it goes up and i have to reboot to fix it...

Using: SD Build, AmeriCanAndroid on Stock WinMo 6.5

some ideas ?

PS: Hope everybody can undestand it my english is not that good :D

Standby Battery Drain

The problem with battery drain 60mA in standby is well recorded for Android: Search: Keyword(s): battery drain ; Forum: HD2 Android and child forums. This particular problem will not necessarily be fixed by Juice Defender, SetCPU etc. There are several approaches:

1) Change your Radio [A] What REALLY improves Android battery life on the HD2 e.g. 2.12.50.02_2

2) Change your ROM [GUIDE] How to make your battery last longer on Android

3) Change your kernel e.g. [Kernelpatch][25.03.2011] Bluetooth battery drain fix

4) Try one of many suggested fixes including

* Different Micros SD card [SOLUTION] Possible solution for heavy battery drainage

* Do not boot Android from WM, use app such as

... [APP] RunDroid-dual boot to (multi) Android [SD] or WM6 OR

... [APP] Exceller Multiple Build Loader for Android/Ubuntu

* WinMo registry tweaks Increase Battery Life [WinMo registry tweaks - Need confirmation]

* disable prog e.g. GPS My test & results regarding the 60mA standby high battery drain in Android -PLS READ

* before boot android, pull out and plug in TF card method for fix HD2 SD android standby battery drain 50+ma

* Dumping ;)

I have not yet used all of these and cannot take any responsibility if you try any of the above!

Your individual solution may depend on your hardware (e.g. maybe SD card), software (including Radio and ROM) and how you boot. SetCPU & Juice Defender will fix some problems but unfortunately probably not the 60 ma standby drain.

Cheers

Hello thanks for your support!

Did you see an improvement of your battery life with my tips? What was before / after?

Back to your questions...

You are running an SD build over WM6.5.

So here are some hints:

SD ROMs usually uses more battery than NAND ROMs in general

The button trick is maybe something real when you launch the Android from WM6.5, however, even if true, it is very specific to SD builds - so I won't mention it in my fiirst post (sorry but I want my tips to be usable by everybody!)

Information for you: there are some aps for WM6.5 that enable automatic launch of Android at phone start. Why this is needed? Because the sooner you launch Android, the better will be the battery life!!! So you should find one of these aps, very useful!

Finally, concerning your "problem" I don't know what to say: try the tracking methods I talked about in tip#10 including reading the thread I linked there.

Hope I could help!

Regards,

Looki75

in battery history some times i see android systeme eaiting a lot and some some times i dont see it and the battery drain

i'm lost ... realy i tried almost all version of radio rom ...but the same result ... i just did a clean installation of the typhoon rom and just installed root explorer and current widget and i will see what will happend
[HD2 Android Q&A, Help & Troubleshooting and Genera] martinsch89:
Hey :)

I used the tricks for auto brightness, cpu clock and internet options... very usefull while using the device... Maybe i should try the WinMo Tweak to fix my problem... The "Button Trick" is the only chance for me so lower standby drain, any other options like putting out SD or Bootmanger for Android dont work for me... (Tried all of them, no success...)

As i said, stand by drain is fine for me now (~5-10mA), drain after calling drives me crazy :D... but i think i can handle it with restarting the device... Maybe 3-4 Calls a week, 99% sms or Mail :D Just tought somebody had the same problem and a solution...

But thanks for you Thread, its very informative... keep on collecting...

rom rom radio ?

after doing a task29, nothing will happend to your radio..

For sure, without radio, you won't have any phone signal, any 2G, any 3G, any wifi, any Bluetooth, any type of connection! :eek:

And even, I'm not sure if the ROM will be able to boot at all...

Strange idea... why would you like to "not flash any radio"??? :confused:
[HD2 Android Q&A, Help & Troubleshooting and Genera] LaneyEFC:
good point but still the radio doesn't need to be touched... once a radio is installed it cant be removed via task29 can it ?

well yesterday i just did a clean install ( task29 ....) without flashing any rom radio just to see if the hight battery drain is caused by the radio rom ... and surprise i got signal and everything ( 2G, 3G, wifi ...) is working perfectly !!!!

i did a research and found that the task29 dont delete your spl and radio rom it only delete the rom and all data ...so you need to flash radio rom just once not everytime.

[HD2 Android Q&A, Help & Troubleshooting and Genera] :
There is no way to not have radio... you can have wrong radio (which can have bad effects) but when you flash radio once you dont have to reflash. Task29 doesn't touch radio... only directly flashing it or Win6.5 with sd method can affect radio.

Do I have to use the Ultimate version of Juice Defender? There's a free version too...
[HD2 Android Q&A, Help & Troubleshooting and Genera] Galactus:
out of curiosity, what is the average SCREEN ON TIME most people are experiencing before & after. I managed 6 hours SCREEN ON time and 4 hours in standby which I thought was excellent. Was playing lots of games.
[HD2 Android Q&A, Help & Troubleshooting and Genera] Looki75:
Ultimate offers many more options.

Free just offers basic functions which will improve the battery life a little bit, but not as much as ultimate.

Maybe you should use the free version for a time and report back the results in this thread?

For me, I preferred the ultimate version - best improvement :D
[HD2 Android Q&A, Help & Troubleshooting and Genera] Looki75:

Well I'm using Juice Defender free, and I'm running 7ma now, when the screen's off. 173ish with it on. But it disables data with the screen off, not sure how I feel about that.
[HD2 Android Q&A, Help & Troubleshooting and Genera] Looki75:
Well those figures seem ok. However, you need to use the phone 2-3 cycles and check what is the battery live from 100% to 0%. And see how much is the improvement compared to before. This is the real test, I mean: mA is nice, but the real goal is to increase battery life, right?

Moreover, as I warned already, mA is just informative and can be very misleading: the system does not continuously monitor the value. So the value is just 1 snapshot. It

does not mean

that most of the time you have 7mA - it

does mean

that last time it checked it was 7mA. Could be a big difference, right?

Yeah... what is your concern exactly?

If you are afraid e-mails will not flow... then read the following.

My JD also disables data when screen off... but: there are the apps rules (i guess this is a function in ultimate in "Triggers Tab / Apps") and I defined my e-mail apps as "enable screen off". This means that when one of my e-mail app is requesting access to the network, even if the screen is off, JD ultimate will open the network, let the e-mail app check e-mails and when it's done, close again the network access!

Result:

your e-mails are flowing as they should, even screen off

sorry about that. this is after using your tweaks.

SD version with low battery

May I reccomend:

Tytung Android Build: NexusHD2-Gingerbread V2.8 SD (Android 2.3.4) | Kernel: tytung_r10

This uses less than 10 ma in standby, is 2.3.4 and supports BT and radio.

Other SD implementations of the same Tytung NexusHD2-GB either have the 60ma high battery drain or do not support BT. I reccomend Tytung "official" version:

On my beloved HD2 (now treasured by my daughter) removing stock email apk helper reduce the drain.

My question... Juice Defender's location training sticks at between 50% and 65% (two tests). Using Beta / Ultimate. Any thoughts?

Would this help battery life?

I'm wondering if running these SD versions of Android roms on their own partition would help with battery life as all my WinMo data is on the same partition as my SD Android rom (at the mo' it's Jaguaralani Gamer's Edition v2).

Does Android waste processing power and time searching through all of this data?

Just a thought hope someone can shed some light, I may even try it when I get some time.

Regards,

Gunner22.
[HD2 Android Q&A, Help & Troubleshooting and Genera] Looki75:
Good point!

Don't worry, training in JD is taking a long time... you should just not care about it. It can take several days...

Important thing is to make sure wifi is ON in your locations (home, work,...). If JD switched OFF wifi while it should not, just switch it ON manually; JD is learning little by little but when learning is still at 70%, it's working pretty well.

In the "triggers" tab (bottom) you could also see several times the same wifi network... don't worry here again; JD is managing all that extremely well!
[HD2 Android Q&A, Help & Troubleshooting and Genera] Looki75:
Maybe, but it is difficult to sort-out and to prove I think...

However, I'm not sure the phone is able to deal with several partitions on 1 sd card...
[HD2 Android Q&A, Help & Troubleshooting and Genera] Looki75:
Yes, Dorimanx ROM is probably the cutting edge of performance!

So let's assume your 60mA drain is confirmed (I mean not just values you see in current widget, but confirmed constant steady 60mA drain).

This drain is either the email.apk app (which can create such a drain) - this app is by default in all Android builds. You should delete it and see if you still have the 60mA drain... if you need e-mail you can use k9 which is ideal.

Or the drain can be from an hardware problem as you suggested... :(

as i said in an older post when i turn on the phone and let it alone the drain in 7 ma and cpu spy shows that the phone was in deep sleep ...but once i unlock the screen the drain jump to 60 ma and the deep sleep state is never used again.
