!!!!Battery Saver Fix?

I'm running Beta 3 Rom rooted ROM. I accidentally hit fix permissions in ROM Manager app and now my battery is seriously lasting about 7 hours longer with the same usage and no tinkering. Also I'm getting less forced closes overall. Not sure why ... and I'm not sure if doing this is very dangerous and leaves me vulnerable going forward. Anyone know if this makes any sense? What does fix permissions do in Rom Manager? Is this a fluke? Try at your own risk ... I'm just not sure. If anyone knows of a possible explanation or is brave enough to try it ****AT POTENTIALLY GREAT RISK *** post your results here. BE CAREFUL ... BE CAREFUL ... BE CAREFUL.

Im trying it .. we see what happens.

How much total battery life were you getting before and after the fix?
I'm running attn1's rom and I get excellent battery life, like literally 1.5-2 full days of average use before it goes down to 0.

I tried it too... there were tons of permissions to fix! Will report back in a couple days

Can you reverse this if you wanted to?

i dont think you can reverse it.
i would reccomend a nandroid backup before you do this.

Quick question, if I needed to wipe to restore settings from a nandroid backup. Would I get everything as it previously was, latest rom installed, with all my apps?

I believe nandroid is a full backup, almost like an image. So if you needed to recover it it should restore your phone to how it was when you ran nandroid.

When you restore a nandroid backup everything returns to exactly how it was when you did the backup, I.e.homescreen, unread texts, notifications, settings apps and all.

Which Rom manager did you use? I got one from the market and installed it. When I attempted to fix permissions, it did nothing. BTW my Aria is rooted and has sideload capabilities. Thanks.

assuming this does work anyone have a theory on why?

Quick question guys. How long does your phone take to fully charge? I've had my phone today from 8am to 7pm
Plugged it in and after being plugged in for about an hour and fourty min. It says it is at 100% but the light is still red. I did repair permissions and rebooted I'll see if it helps tomorrow.

How do you guys do the fix permissions thing? I have the liberated Rom and my battery only last like 7 hours
Sent from my HTC Liberty using XDA App

you have to use Rom Manager, download it from the market. you have to have clockwork recovery installed also. Now 7 hours for battery life, is that under heavy, moderate or light use? if thats under heavy use thats not bad at all. also depends on what widgets your using and how your phone syncs, updates weather etc. theres alot you can do to optimize battery life without the permission fix, if it even works?.

it depends on if im using my phone while its charging, it can take anywhere from 1-3 hours, or more if it gets hot and stops charging. and what percent did you start charging your phone at? from like 15% to a full charge without using my phone, itll take approximately about an hour and a half

It was 15% and it took ~2 hours to reach 100% and turn the led green. so i basically got 11 hours with medium heavy use which is pretty good.

General Battery tips.
Remember you are running a lithium ion battery, that means it is important to get a full charge on the first charge, and also charge it as often as possible. Letting it often get to the critical state can have long term negative effects on battery life. Such is the limit of our battery tech.
Optimize how many apps you have running, use advanced task killer etc. I also heavily recommend that you change how often your phone looks for updates, facebook notifications etc.
Turn gps on only when you need it.
Ditto for wireless.
I let my phone auto the brightness of the screen.
I generally get 2-3 days battery life, I talk for approx 1 hr a day. I watch videos/ play emulators for 1hr a day and I frequently text, update calendar information, and setup checklists.
As far as permissions go, chances are if you declined on many of them, some of your apps can no longer check for updates etc. So you are suddenly getting the battery life I get by making sure my apps are always dead unless I need them.
Also remember, many apps turn on automatically when you restart your phone, so run the app killer when you boot.
Good luck.

Best rom for battery life?

I have been bouncing around from rom to rom trying to figure out which has the best battery life, its too hard to tell. I know that htc sense roms killed my battery off faster, but no matter what it tends to die off much quicker than it did before I put android on it in the first place. Anybody have any suggestions? Thanks

Iamgpc gingerbread is great as long as Bt is turned off when not in use.

Here's the thread:

I did the same as you, rom hopping...
But everytime i came back to where i am now:
AF403 Desire HD
This is a great rom for your battery.
But as in any rom you should think about what you wanna sync and when.
I use LauncherPro instead of Sense, and I think it better then Sense.

Thanks, so basically 2.2 rom's without sense? And does apps2sd or ext4 have any effect on battery life?

One suggestion for people that are concerned with battery life...
I recently did an experiment of sorts and turned off 3G on my phone. I found that I went from 1 day per full charge to 3 days per charge. I obviously didn't have updates from the email app, twitter, facebook etc., but I just turned 3G on every now and then and updated everything manually. I've since started leaving 3G off whenever I don't need it and generally get 2 days use out of a full charge.
Obviously this won't suit everyone, but if turning off 3G when you don't need it is an option for you then you will definitely experience a much better battery life!

For best battery, don't use Sense.
For best internal memory use ext4, this is better then apps2sd.
This does not realy effect your battey

I really love this build "DL DesireZ v3.3 final][DL Data2SD/Ext4 v2.3][Nand/SD/MAGLAR]"
can be found here http://forum.xda-developers.com/showthread.php?t=913597
It's a NAND version but there is SD version as well.. (nand v. download link can be found on page 192 because the author didn't update the post yet)
For me it's perfect. The battery life lasts for a complete day. I listen to music about 2-2.5 hours, use internet for about 20-30 min a day and make a few calls. But I always turn internet off when I don't use it it really saves battery (i think it works for any build). Also 1 day I listened to music for 6 hours, used internet for +-30 mins and there was still 37%. I was really impressed!

Decent battery life
Currently I'm using- MDJ's CyanogenMod 7 v. 2.6 and my way is to switch off data. I'm switching on whenever I need. With regular use of data( switch on/off) my battery last for almost three days.

Are you serious? I mean I haven't tried CyanogenMod 7 ROM but what I remember back to stock WM6.5 it was easily last for 1 day for me with normal use.. And now I have the same results on Android (desirez v3.3 rom), I'm very satisfied with that. However 3 days it's kind of hard to believe or I'm wrong? Anyway, how much do you use your phone during the day?

[Q] Reverting to Windows Mobile 6.5

I flashed Android to my HD2 using NAND and now I want to go back to WinMo 6.5. Can anyone tell me how to do this.

Get the WM ROM you want to install and enter the bootloader - turn off the phone and then hold down the volume down button and briefly press the power button. Keep holding the volume down button till you get the tri-colour screen. Connect to PC via USB and run the WM ROM installer.

Download the original ROM or custom ROM.
Put your HD2 in Tricolor Bootloader mode by holding the VOL-down button when powering on.
Flash your ROM.

Where can I get the WM ROM?

Why would you want to do that? Andriod is awesome and better suited to the HD2 than the WM it came with...
But each to their own.. Try the following link...

I'm with Oscar, i am going back too. I have downloaded setCPU and tried all the other suggestions but I am still burning through my battery at a ridiculous rate. I like the Android OS but I need a phone that will stay charged for longer than 12 to 14 hours while in standby!

Android kills the battery. Less than 4 hours a day, that sucks!!!!

I've not had the battery issues you've mentioned. You don't happen to be leaving bluetooth running do you? This has a known issue with battery drain.
I don't use bluetooth and I get extremely nice battery life with the gingerbread android builds.

I get 48 hours without any tweaks at all on almost every Android I'v installed. Currently I'm using CoreDroid and my standby battery drain is average 2-4 ma with Current Widget. You guys are CRAZY for going back to winmo but I guess some people just can't stand a way better OS

Its because you are either using an old/crap rom or you havent done enough research.
I have tried MANY roms and most of them now have excellent battery consumption. Between 1-5mA on standby.
Make sure you try things like remembering to turn off bluetooth/wifi when not using them aswell as have a upto date kernel/rom, also make sure that your radio is a uptodate version.
There is loads you can do, you simply cant be bothered, that is your problem. Battery consumption used to be a big problem, that simply is not true anymore.

[Q] longest battery life?

Hey guys! I'm going to a trip to Poland to see Auschwitz and all that stuff about the holocaust with my class on the nesxt monday, and now i'm wondering which rom for our device that got the longest battery life?
I'll just be able to load the battery on every second day and i want to upload 2-4 photos everyday to facebook and i want to be able to take photos without the batterys going to 1%
Right now I'm using SwiftDroid but the battery isn't that good, so.. which rom do you think i shall use?

2.1 custom roms are good.
Sent from my GT540 using XDA App

sanmit: Which of them do you think is the best? And do them got Swedish/Svenska as language?

Stay on SwiftDroid, but reduce the clock of the CPU to stock 600MHz (or lower) max and 122MHz min. Try to turn off any fancy animations of menus etc. Use static wallpaper instead of live one. Turn off screen rotation, wifi, BT, GPS. And AVOID USING THE PHONE until You need it actually (reviewing pics etc).
That should maximize Your battery charge.
Have a safe trip and have fun!
P.S. Oh, and I forgot to mention to turn off (remove temporarily) any widgets like clock, weather...
Try to find a compromise in all this stuff and stick to it.

MomirPeh: I'm already using my phone like that and still the battery is kind of crappy

I think the Quarx 2.1 rom w/ his custom kernel is very good with battery. If you want to try it, download it from my Dropbox In this .zip is the system.img, boot.img and an update.zip file. The update.zip file contains a fix for the device rebooting when Wifi is turned on. You HAVE to flash this .zip with Clockworkmod 2.0 (2.5.1.8 recommended)
Hope it helps,
Jack

Swedish language support...not sure.
But i can say 2.1 mmxtreme advanced gives me 3 day usage with moderate audio-video and wifi.
Sent from my GT540 using XDA App

Just use the Open Europe v20B stock ROM. No custom ROM gives a battery life better than a stock one. And one small tip. Do not use 3G. It drains that battery much faster. If you gotta use data, use 2G.

Definitely 2.1 mmxtreme Advanced Lite rom! I use my phone quite often, and no rom gave me more battery than that one! Turn of background data, 3g, mobile data, and other stuff like that. Use an advanced Power Widget or ZDBox to have them all "use-ready" all the time

DHD become faulty??

Hi,
Over the last few weeks I've noticed that my DHD battery is not lasting as long.
It has got seriously worse over the last 10 days. Phone gets switched on about 7.30am and by 4pm is nearly out of juice.
Not really doing anything with the phone - just sitting there on the mobile network with good cell signal. BT is off. Power saving is at maximum levels (no animations etc). It used to last until around 10pm and still have a good 6 or so battery segments left, but now it'll be dead by 6pm.
Nothing recently installed.
Any ideas on what may have changed?

Install currentwidget from the market and set it to log current usage. You will probably find your phone isn't going into deep sleep which is caused by a certain app.
Also see which app is using most battery. This could be an issue. On average 4-10ma on standby is seen.

I feel your pain buddy, my Dhd used to only last about that amount of time before I rooted, but then again I used to be at it all the time so not exactly the same set of circumstances. Must say I've been pretty happy about my battery life since flashing a new ROM but there's still no way i'm gonna get a full day from it

BTW - forgot to say that when checking whats been using the battery, it says display is the component that be using it the most.
I always hit the sleep / power button when finished with it so it doesn't drain the battery.

I've considered rooting it (It's an Orange UK supplied device btw) but I'm scared of breaking it.
I put a ROM on my previous phone so I do have some experiance of installing ROMs so I think it'll be ok if I did it.
Could I put the latest stock HTC DHD ROM out it without any issues and what benifits would I gain?

I've been very pleased with the virtuous unity ROM, it's got sense 3.0 and is super smooth, much faster than stock and better battery life. I couldn't see what benefit you would get from flashing stock room again though but i'm sure you could check it out on the forums if you're unsure.
I used http://forum.xda-developers.com/showthread.php?t=1259821
And had no problems rooting whatsoever, just be sensible and backup your data and stuff and you should be fine I'd say. Dead easy process too, it's much less hassle than going through all the different steps that you had to before, just make sure you read through the details and you'll be fine
