but when i reboot it goes back to value 1

is it possible to do a custom rom based on this??
[Windows Phone 7 General] JamesAllen:
Reboot

When I do a soft reset these registry changes remain as I changed them. That is, I changed them to 0 and they remain that way.
[Windows Phone 7 General] Magpir:
now its working, i changed all the 3 values below to 0

and rebboted, now it stays at '0"
[Windows Phone 7 General] ahlMAR:
are the changes notable?
[Windows Phone 7 General] Magpir:
so far all is working fine

I found another entry : legacy power management with dword value.

Not sure what it does.can some expert explain
[Windows Phone 7 General] snickler:
This is an interesting development. I will test these changes out. Maybe I'll have Marvin_S update the DiagProvXML app with these keys.
[Windows Phone 7 General] Magpir:
Another is the sdcard blocks size of 128 . I changed all entries referencing this from 128 to 512 .

this two entries may edit every one with stock rom interop unlocked. After soft reset they are as I set, i'll make some tests. after two days we will see ;)

this key is not available for me on interop unlocked focus (stock rom) the other two are. Can i just these two and would it improve battery life?
[Windows Phone 7 General] Magpir:
according to logic it should...

because its part of how windows works
[Windows Phone 7 General] JamesAllen:
Focus

Strange, it's available on mine.
[Windows Phone 7 General] sensboston:
Don't play much with registry; it will not improve your battery life just mess system settings. The real reason why the Mango's power consumption is worse than NoDo, it's because of lot of new features added to Mango (new online background data services etc.) So do not waste your time... Real advise is to use extended battery or wait for the new OS release (if MS will improve battery life of course).

Hey, Magpir, I already gave you a perfect advise: install Martin's Battery Status app, and show us your battery life charts for a week (now you can easy access statistics file, see Battery Stat topic). And anybody can see results of your "improvements"...
[Windows Phone 7 General] Magpir:
well intrinsic rom in another thread, was stated to be using these power management tweak

Win phone OS is just like our PC windows, need to be tweaked
[Windows Phone 7 General] weijoon:
If I can thumb down, I sure will do this...

----------------------------------------------------------------------

I don't believe that only a few line of registry tweak can make such huge difference on battery consumption that user will aware...

Magpir,

Sorry to say this, perhaps it is time for you to move along from this battery issues / tweaks that you keep sharing to people, sharing is nice, but sharing without facts proof is bad for everyone...
[Windows Phone 7 General] Magpir:
not really, wp7 like all windows products beahves funny

interestingly my battery lasts longer when charged under 2G than in 3G

what i mean. before i put the phone to charge, i switich it to 2G let it charge overnight. then take off the charger , turn on the 3G again, it seems to last longer...

Just tried it last night,

under deepshining rom
[Windows Phone 7 General] majkeljj:
on WM 6.5 HTC Touch Pro few registry lines makes significant difference in battery life and this two lines I think are almost the same like in WM6.5 this was made by Advanced Config 3.3

some registry from WM:

and discussion:

http://xdaforums.com/showthread.php?p=1484120&highlight=disablepowermanagement=0#post1484120

my "Pictures" tile open a half of second to 1 sec. longer that's probably means that SD Card powering is cut down when we don't use SD Card, but for now I don't see any significant improvement (I use my phone very hard, maybe on standby will be difference)
[Windows Phone 7 General] XboxOmac:
If you don't use an SD card, does this make any change?
[Windows Phone 7 General] Magpir:
not sure, but these are most probably for wp7 devices like HTC using microsd HC as main storage device
[Windows Phone 7 General] majkeljj:
I added to registry new values:

HKLM\Drivers\SDCARD\ClientDrivers\Class\SDMemory_C lass\High_Capacity

DisablePowerManagement=0

HKLM\Drivers\SDCARD\ClientDrivers\Class\MMC_Class\ High_Capacity

DisablePowerManagement=0

HKLM\Drivers\SDCARD\ClientDrivers\Class\MMC_Class\EmbeddendHigh_Capacity

DisablePowerManagement=0

I will test it and we will see if it will change something.

with previous changes there was no significant improvement.
[Windows Phone 7 General] Magpir:
maybe the registry editor was not working .

I believe intrinsic rom has this already modified by default. No wonder it has some excellent battery life on my phone.
[Windows Phone 7 General] Leapo:
I'd like to see some proof that this actually does something... and if it does, are there any negative side effects?
[Windows Phone 7 General] Magpir:
I found it increases my battery life after a calibration .

No negatives effects so far .
[Windows Phone 7 General] majkeljj:
no negative effects so far.

I would like to get working Set AutoData, but on my mozart don't work, or maybe I don't know whre to enable this :P

[HKEY_LOCAL_MACHINE\System\AutoDataConfig]

"RunADC"=dword:1

"ConfigurationStatus"=dword:0

[Windows Phone 7 General] Magpir:
i believe u need to be interop unlocked to use this
[Windows Phone 7 General] majkeljj:
i'm interop unlocked :) without that there is no possibility to edit registry.

but id doesn't work or i don't know how to enable it or it is something differ then I thought;) I understand that this option swich off data connection after some idle period, am I right?
[Windows Phone 7 General] Magpir:
i do not think so...

battery saver in mango supposed to do that
[Windows Phone 7 General] majkeljj:
option = i mean registry entry

[Windows Phone 7 General] Magpir:
i beleive this registry entry is related to MMS and not 3G or data connection

I read somewhere in these forums
[Windows Phone 7 General] Magpir:
i beleive what u r looking for is here

HKEY_LOCAL_MACHINE\Comm\ConnMgr\Planner\Settings\

SuspendResume = ????

CacheTime = xxx (where xxx are seconds before auto disconnect)
[Windows Phone 7 General] sensboston:
This guy will never give you a proof, because there is no improvements at all. Battery Status app can show the real situation but Magpir will never show anybody his battery statistics :D Hi is "believer"...

And the negative effects are: you waste your time for useless "tweaks", and have a good chance to damage phone registry :D
[Windows Phone 7 General] majkeljj:
yes, your right :)

no access to this registry on interop unlock :(

I like tweak if I broke I will make hard reset, no problem for me.
[Windows Phone 7 General] sensboston:
I envy you. At the beginning of forties, you'll realize that time is a very precious thing...
[Windows Phone 7 General] weijoon:
I doubt that if you ever fully read and comprehend the whole thread.

First link talk about WinMo Rom with bad battery life in Zimage Android, it is easily to understand that because the OS is actually in SDCard, which makes it keep read write even when in sleep mode, tweak enabled make the sd card forced to suspend when in sleep, thus battery life improve, negative side, Android wake up from sleep slow plus sometimes corrupted file. (Don't question me about this, I had indeed try this before).

Of course, Zimage android normally is not optimized in every term, in your case, battery life.

2nd link you provided also only showed IMPROVED battery life (no actual fact provided) plus at the end it is the HTC home plugin that draws the juice and that's why I always off the HTC home when in WM6 days...

Still, I'm insist on my stand that only a few registry tweaks will not SIGNIFICANTLY improve your battery life...

But indeed I can confirm that 8107 update draws battery life more than 7740, with same apps count and setting, with my average daily use.

---------- Post added at 11:23 AM ---------- Previous post was at 11:21 AM ----------

I already realized that on my early twenty (present)...
[Windows Phone 7 General] majkeljj:
yes, thread is about android, but these are entries of WM.

yes, there is no official proof, but my HTC Touch Pro battery life is better with this settings.

8107 update may have better battery then 7740 because on my mozart 7740 drain battery quicker then 7720 Mango so you can see theoretical improvement (for me close to 7720).

few years and I will be 40;) and even now I know taht time is very precius. I have installed only 7720 Mango with first HTC drivers, almost no apps, no music and video. So after hard reset I need just unlock my Mango phone via chevron token, install htc unlock xap and i'm back interop unlocked, sync windows live via wifi. How long will it take me? maybe 5-10minutes. This is my secret ;)
[Windows Phone 7 General] Magpir:
this is my battery life after applying the tweaks, rest on standyby
[Windows Phone 7 General] majkeljj:
great score, but it is not reliable, sorry to say:(

My shows:

Remaining batt: 71%

Estimated time: 2 days 20 hours

Timie since: 1 day 3 hours

and i'm sure that my battery will be dead to the end of day ;)
[Windows Phone 7 General] Magpir:
so far on standby i get good figures to show this tweak is working

yep battery saver figures is not an accurate indication of battery life a sa lot of other factrs on how u use the phone , 3G signal quality ect does matter .

only useful on standby for observing elapsed time

but people here ask me for batt stats

so i posted it. keeping mind i did not say this tweak will improve batt life definitely. its just a supposed battery life tweak that is the same one found in win mobile 6

so far the best rom i used which has good batt life is intrinsic rom, which was stated to be using this tweak
[Windows Phone 7 General] majkeljj:
yes I know.

I think that they talked about log from this app:

http://xdaforums.com/showthread.php?t=1328730

but I don't recomend install it, my mozart drain battery much quicker with this app, and I know that they write that it doesn't drain battery, but my experience are other.
[Windows Phone 7 General] Magpir:
battery status seems to drain my battery too,

u have no use for it if u use intrinsic or eburon which show coloured battery level ( yellow, blue, green red. Red is below 30%)
[Windows Phone 7 General] Magpir:
edit: i reinstalled intrinsic rom to double check , as expected. this tweak is found in the intrinsic rom 5.02 by default.
[Windows Phone 7 General] Ttblondey:
So does that mean Intrinsic rom consume battery alot?
[Windows Phone 7 General] Magpir:
No it will be the opposite.. intrinsic will consume less battery
[Windows Phone 7 General] sensboston:
Definitely no. It just means that Magpir continues to write complete BS and lie.

Hey, Magpir, stop posting your stupid screenshots! If you are really wanna proof your words, install Battery Status, and show us your statistics for a week or two.
[Windows Phone 7 General] Magpir:
this will not be accurate because , firstly my phone is on the move all the time, in areas, with weak and strong 3G signal, different usage , heavy, light , no usage at all ect...Battery status does not have standby and usage time as separate like android and IOS where u can use average to judge battery life

but what i can tell u is that compared to other roms, including stock rom, Intrinsic has better battery consumption in usage and standby , because i can feel the difference . it has solved one major problem i had both with stock and custom roms in the past - Battery rapidly draining to 80% after taking off the charger. Not sure why it stay at 80%, the other being erratic battery behaviour ( sometimes good, sometimes bad consumption).)

sensboston, judging from yr profile threads, u dont seem to be contributing useful threads in technical dept. my intention is not to tell lies.

I may be wrong, but at least i am trying to do some research here. there are "funny things" which happen with hTC phones , like that turn on/off charging trick 10 times ect.Most of these people who discovered this tricks found it by accident and thru observing, experimenting . so u may never know what u can find , like a box of chocolates. there are problems wit HTC phones yes, but at leaast they dont blow up in yr face like iphones

for those that see no difference after enabling this tweak it means registry editor is not writing the tweak or maybe u need to flash a custom rom with this tweak enabled in it from scratch like eg. Intrinsic or any others u know of
[Windows Phone 7 General] sensboston:
What I can tell you from your posts here: you are publish UNVERIFIED non-working "tweaks", advising people do things which can damage/mess their phones.

Battery Status statistics IS ACCURATE; actually it's THE ONLY ONE TOOL for WP7 what can tell you the truth. Battery saver estimation is incorrect and useless! And OF COURSE (sic!) the correct power consumption statistics SHOULD BE collected during regular usage: "light, havy usage, strong 3G signal, weak" etc...

I know why you don't want to show your statistics: it's because your phone battery life (after all yours stupid "experiments") is MUCH SHORTER than average XDA member LOL
[Windows Phone 7 General] Magpir:
well, my phone is working fine . And battery life with Intrinsic is excellent.battery status shows u graphs and mv and such stuff which can be influenced by many factors like 3g signal ,radios on ECT

IF want an accurate reading u need battery stats like those found in IOS AND ANDROID.
[Windows Phone 7 General] sensboston:
I don't believe you, prove it!
[Windows Phone 7 General] Magpir:
well i can show u some stats but how do u know whats the stats like in usage, standby ect.

we simply dont have that kind of features in battery status app or the battery saver stats

or i can even cheat by turning off 3G and put it in 2g mode, of course this way i can prove falsely that i have battery life improvement

come on dude, the only way to judge is by observation yrself. I was so used to the poor battery life in stock roms or other customs that i can immediately notice the difference in intrinsic, this is not a placebo illusion

if it is real means its real, no doubt. u will be able to see it straightaway

i was on the intrinsic rom for 2 weeks and the result have been constant throughout before flashing to Deepshining to check out its features

but now i am back on intrinsic, and deepshining batery life isnt that good compared to intrinsic and also incidentally the power management tweak is not found in deepshining. Verified by seeing thru registry editor
[Windows Phone 7 General] sensboston:
No more cheating and BS, please! Just:

- install Battery Stat;

- add live title;

- set Update interval in settings to 10 minutes;

- collect data of your usual usage for a week;

- using desktop viewer, download data and post to the Martin's shared folder or attach to your reply.

Anybody will be able to see how real your "improvements" and good your phone's battery life. If you are really made some progress, you can generate and publish here a few impressive charts...
[Windows Phone 7 General] GoodDayToDie:
Oh please, you two are like children fighting on a playground.

@Magpir: Nobody cares much about personal anecdotes; the plural of anecdote is not data. Any time I see a sentence with "it feels" I assume it's wrong until demonstrated otherwise. Running the Battery Status app for a week each with logging enabled and your tweak first not applied, then applied (but otherwise the same level of usage) wouldn't be *that* hard. Note that the background agent on Battery Usage has a tendency to stop working after a few days on my phone, though.

@sensboston: Is there a reason you're being so critical of this particular tweak? There are lots of useless tweaks, and a few known-dangerous ones, posted all over this forum, but typically people don't get into a pissing contest over them. If you want to prove Magpir wrong so badly, why don't you take your own advice with the Battery Status logging? So far as I can see, you don't have any more actual evidence for your claims (of really bad battery life when these tweaks are used) than he does for his... and at least his arguably make some sense (turning off a "disablebatterymanagement" option could certianly improve battery life, though there's probably *some* reason for the default - but it might not be the one you'd expect at all).

Seriously people, let's have some maturity please. The closest I've seen to this was when Ansar duplicated DFRouter (by re-repackaging an HTC OEM tool), told everybody it would work in places where DFRouter didn't (false by every report including my own testing), and actually got called out on it... and even that didn't devolve to the level of this thread.
[Windows Phone 7 General] sensboston:
@GoodDayToDie, you are probably haven't followed the topic well (I mean all topics what Magpir already created). I'm explained my point of view many times; Magpir's "advises" sometime are really useless or terrible (kinda like put phone/battery to the freezer or do a complete reset of the handset or pull of your SIM card etc. etc.)

Why do I criticize him? Maybe I want to be helpful to XDA people and protect them from wrong advises problems. I don't have any commercial interests, believe me :)

Mango's power consumption problem can't be resolved by tweaks or "magical rituals"; I and Martin (singularity0821) are already working on some kind of resolution but it will take time of course.
[Windows Phone 7 General] Spookidoodles:
I'm gonna have to agree with Sensboston here (and not just because he has done me a favour!)

Look at the amount of people that post on this site - think about the sheer amount of people that don't - when it comes to WP7 and problems most Google searches actually bring you here. I'm not a complete noob and wouldn't do anything as stupid as certain things Magpir has suggested in his threads, (since when was putting anything that isn't meant to go in a freezer, in a freezer a good idea?!?) but there are a considerable amount of people with even less tech knowledge than myself (of which I have only a basic understanding of), that will literally do anything the internet tells them to do if it's stated that this stuff genuinely works.

Hell, I have to go and reinstall Windows on my mums PC once a month because of the sheer amount of goddamn adware she manages to infest it with - all Sensboston is trying to do is make sure that one stupid person doesn't ruin 100 people that aren't tech savvy's devices.
[Windows Phone 7 General] GoodDayToDie:
Fair enough, but if you know of a problem with a suggestion online and the author doesn't want to remove or edit it, the correct approach is to bring the moderators into it (Report Post button), not start a fight over it.

Also, for the record, putting "[things] that isn't meant to go in a freezer, in a freezer" is occasionally a good idea. For example, you can sometimes restore a dead hard disk (head misalignment/scratches) for long enough to pull a little data off of it by putting it in a freezer and letting the metal contract a bit... but it's a weird suggestion for batteries, as generally a battery works better when moderately warm (depends on the battery chemistry, but there's an optimal temp for all batteries and it's usually above freezing).
[Windows Phone 7 General] majkeljj:
Ok people. Please remember that these entries was alsu put here by nown developer see post 2. You also can find these tweaks in hd2 section regarding wp7. I tested them personally and don't break my phone. There is alsi no significant improvement on my mozart but worth to test it a little longer. Battery status is not good because ex. On my mozart drain battery a lot so may eat everything what we earn.
[Windows Phone 7 General] weijoon:
Extra side note, i normally use battery status app in a 30 min interval, still get battery stat quite accurately and can keep track the caused of my battery drain.
[Windows Phone 7 General] sure haven't:
This Magpir person is making **** up. Do NOT follow any of his advice. His "instructions" are completely and utterly nonsensical.
[Windows Phone 7 General] drupad2drupad:
I think everyone is lying.

If this works or not can only be proved by battery stats graphs.

People for or against this tweak have NOT attached a single battery stats graph.

So this idea is as good as it is bad.

If you think it works - show me the graph!

If you think it DOESN'T work - show me the graph!

Else, each post starts with .. "Here is my BS..."

PS: I would do it in the name of research, but my phone isn't interop unlocked and cannot be done so yet.
[Windows Phone 7 General] Magpir:
well i said already . Intrinsic has this tweak enabled by default. Intrinsic rom is working fine onusers phone..

If u installed custom roms, more or less they contain these sorts of tweaks ( deoending on the skill of the rom builder)
[Windows Phone 7 General] weijoon:
Agree and Agree!

No Interop Unlock, can't test and show the result!
[Windows Phone 7 General] Loco5150:
Can someone post the original values for this "battery tweak"? I have a feeling that my battery would not lst as long after. OK Im not sure, but that does not matter, I want to test with the old values. Thanks.
[Windows Phone 7 General] SuperSport:
Just put all three values back to one (1).
[Windows Phone 7 General] Loco5150:
If I remember correctly one of the values was not 1. I could be wrong but I will try setting them all to 1. Thanks.
[Windows Phone 7 General] Magpir:
the default is 1

the tweak is 0

cant recall any default value as 0. all of them were 1.

well its always best to flash a custom rom that has this tweak. Something tells me just editing the registry will not work . but dlashing a custom rom with the tweaks in place ensure that they work. but if the tweakis working , that is u set them correctly and is registered

i am not sure, but intrinsic may have other tweaks that work alongside this as well.. i notice an entry called registry persist in the intrinsic rom. maybe this is needed for the tweak to work . I am not sure though but finding something there not originally in the first place means it does something,
[Windows Phone 7 General] nickislauw:
just tried this on my trophy.

and can confirm all the values are by default "1"

will see if my battery lasts longer:)
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] PurpleMelbourne:
OK this isn't a guide yet. Its actually a question.

What are your tips for checking and fixing battery drain and overheat problems?

If there is interest then I'll make one up in the General forum from information posted here. Or maybe someone else will do it and save me the trouble. Either way, many Note users need help with a comprehensive process to track down the cause of overheat and battery drain.

Just setting a high temp profile is not enough! Your phone should never overheat in a normal safe working environment.
