My battery saving tips (40-50h) - HD2 Android Q&A, Help & Troubleshooting and Genera

After many attempts, i have found the best combination of rom, radio, android, and phone settings so my hd2 t-mobile now can last 40-50 hours from single charge.
1. Energy rom without addons on home screen
http://forum.xda-developers.com/showpost.php?p=8640264&postcount=3
2. Mccm se V3.4 version for Android (with r8.5.1_eb kernel)
http://forum.xda-developers.com/showpost.php?
p=9241013&postcount=2
http://forum.xda-developers.com/showthread.php?t=787588
3. Radio 2.12.50.02_2
4. Exceller Multiple Build Loader
http://forum.xda-developers.com/showthread.php?t=737001
5. Set wm in airplane mode, and turn off auto sync, background data and location in android, brightness to minimum
6. Use wifi, gps, mobile data or bluetooth only when needed
7. Install SetCPU and use settings from tihs page
http://forum.xda-developers.com/showthread.php?t=734886
8. Use widget taskkiller every time before locking the phone.
With this settings my phone can last around 50 hours with single charge, and i use it for sending messages, calling, browsing over wifi and occasionally playing angry birds.
This represents moderate use for me, and it is enough for my daily use, but if you want something more buy spare battery
Warning: I own hd2 t-mobile version, so this combination maybe doesn't work on your phone, or maybe it's not compatible with your hd2!
Please check radio and rom compatibility before flashing!

i believe you that your phone lasts more than 40 hours, but not everyone wants to disable auto sync, location and look onto such a beatiful huge screen which is almost dark
i prefer daily charge (lasts about 24h) with all the benefits which a smartphone has!
thx anyway for sharing your setup. it might help a lot of people.

Yes, but maybe someday you will find yourself on a desert island alone with your hd2, and my tips will surely be helpful to you

Looks like Battery Indicator, free version available on the Market.
PS: Do you have an extended battery? (since 8.5.1_eb is for extended batteries)

No, I use 1200mah battery, hd2 stock battery.
And yes, it's battery indicator app, but it came preinstalled in my version of android.

all things that make it a smartphone, are off.

Well guys use your phone as you want, no need to be sarcastic, maybe this will help to someone!
Maybe i would use data plan as well but it is just too expensive on my network, so i use my phone diferently than you

so... sorry to possibly hijack Your thread a bit my dear OP, but can You tell me my friends, how long can Your leo survive constant net usage? my standby drain is great, however when browsing with wifi or 3g, hd2 will live for about 4 - 5 hrs at most (well... let's call it a total net usage, as I've never had time to discharge it in one go... ).
is it more or less what You get? am I overreacting a bit??

My ROM and Android Version is not the newest and I did not look of the combination I installed, so I might have a rubbish setup. But atm. I can't get over the day with browsing, lessening music, data connection and a few calls and mails. Normally I run WM at daytime and after work I switch to Android.
Do you guys get over the day with a normal usage (like 16h), or do I expect to much??

I will try and let you know ;-)

well... if I use it lightly (some web browsing, quite a few calls and txts, some email, etc.) then it will even last two days (less than 1% batt usage per hour in standby), however if I'll use net heavily, gps, gaming then combined use will be only about 4 - 6 hours.
I am changing radio from 2.14 to 2.15 in about an hour to check if it's going to be any difference.
my setup is: stock wwe 1.66 rom, android rom is froyostone 3.2 sense with hastarin kernel 8.5.1 and letama's patches.
[EDIT]
to stay on topic - I have setup as above, auto brightness, data connections enabled manually when needed. with "dumb phone" usage (texting, calling, some notes, calculations, calendar use, etc.) plus some light browsing I had 50% of batt left after all day yesterday. (unplugged @7am, 50% @9pm)

i get on average 48-55 hours with out diableing background, wifi and gps on alll the time. syncs 8 diferent email accounts every hour + the gmail is pushed .
ie: i use it as a smart phone.
worst i got was about 35 hours, kids were playing angry birds non stop...

Using the latest DarkStone and Hastarin 8.5.1oldcam, having auto killing tasks that I don't use, and setCPU at 1.07 Ghz I can last all day.
My first run on Android with my HD2 battery was terrible. but the new Kernel, and using the EB autoboot made battery totally improve, but still worse than my Nexus One. I have sync, and GPS disabled, Email updates only every hour, Twitter every 2 hours. and mine usually has around 60% left after work at 6PM, and It's fully charged and gets unplugged at 9:30 every morning.. so 8 hours and it's almost halfway gone, but when I'm not at work it lasts longer, cuz at work I constantly loose 3G, and get it back and it's constantly switching. I try to set to 2G while at work if I don't need 3G.
I change it on the way home, and use it the rest of the night.. no worries for me.

How much data usage!!??

So, I use netcounter to keep track of my data usage, as I'm sure many others do. My Vodafone contract, that I started a year ago with my HTC Magic, gives me 500MB a month. This has always been plenty - sometimes getting a bit close if I decide to download a couple of custom roms while out the house.
The last week or so though, my usage has SKYROCKETED for no apparent reason.
Netcounter says I've used 302.95MB of non-wifi data TODAY, and it's 9:30am!! I've just woken up! PLUS I've had wifi turned on throughout the night!
What seems suspicious to me is that of that 300+MB only 8.23MB was recieved - 294.71MB was SENT from my phone, between midnight and now, over 3g, when it was connected to the wifi the whole time.
I've apparently used over 1GB in the last 7 days. 90% of which was sent from the phone. I have absolutely no clue what is causing this, and to be honest I'm somewhat praying that it's a glitch with netcounter... otherwise my phone bill is not going to be pretty...
Anyone know of any apps I may have installed that could be causing this? Or any other processes that could have the same effect? As it was so much data sent I thought maybe it was different apps sending anonymous usage data, but switching off all of those that I could find doesn't seem to have solved it D:
I used about 700MB last month...
My bill says 3,7 Gigas...
I tend to use & abuse tethering...
12€ unlimited data plan. Isn´t it at Voda UK?
Check what apps/services are running, could be something going a-miss somewhere.
Seems a bit wierd you had a load of xfer over 3g even with wifi enabled though - maybe try and force 2G only and see what the logging program says then?

Sadly unlimited isn't actually unlimited. 500MB "fair usage" and I think you get charged when you go over that...
As Highland3r says: just use wifi and force 2g only. I use netcounter too, and it says I've only used 3.6mb 3g and 130.73mb over wifi in the last 7 days (only had phone for 5 days actually).
If you think it's a glitch try reinstalling netcounter or something.

40MB used in the last 5 days, ( i havent downloaded any ROMs for a while though lol)
Maybe u shud try using 3G watchdog at the same time as the app your using at the minute
it will show you if the app is messing up or just confirm that you are somehow sending alot of data to someone through 3G
Same thing happening to me!
Although here in Argentina is much more limited, but I try not to use EDGE, and it consumed 1mb download and 26mb upload.
I don't know what does it upload...

If you are using the news and weather widget to display news stories, you'll notice that every single time it cycles to a new story it uses a tiny bit of data. If you've set it to also download pictures for stories, I could see how overnight it could use a ridiculous amount of data.

You wouldnt expect that to upload data though?
Did you try another app to measure and/or killing 3G and seeing if that makes a difference?
It's probably a wild guess, but do you use the Voice Recognition a lot? It send the audio to Google and returns text, so it uploads much more than it downloads.
But I don't think it would be that much.
Well even with wifi turned on, andriod by default puts the wifi to sleep when your phone(display) does to sleep too. So if you had some culprit program running the background, even with wifi turned on it'll still use the cell network by default as long as your phone as asleep.
So... I've been monitoring the usage throughout the day...
Reached about 20MB of data over wifi today, which is reasonable for the amount of browsing I've done on it. At last check (about 2-3 hours ago) cell data was at 0B, as it should be with wifi on.
Pulled it out of my pocket just now - 3G icon was in the notifications bar... thought that was probably a bad sign... 65.42MB 3G data used... 95% sent, 5% received...
ARRRGGGHHHH D:
I never use voice recognition. What the hell is uploading all this data? And WHAT data is it uploading? /:

Sensorly turns itself on if you do any of the following:
Turn on or off GPS
Turn on or off WiFi
Turn on the phone
In addition, when the app starts, it will turn on wifi.
It's a cool app, but if you have GPS on, and it kicks in and you forget to kill it, your battery is down 50% in an hour. It's extremely frustrating that something so useful is so damn annoying. It's almost malware. I uninstalled it from my phone.
I uninstalled sensorly last night... so it's not that.
Might try uninstalling WaveSecure. Pretty sure it's not auto-backing-up anything as on the site I only have the sms and call data from when I purposely told it to back up... but worth a try...
the only other apps I've added recently are...
Gmail Notifier
Gesture Search
Dialer One
that's about it... ):
I had the same issue a couple of weeks back, I was at the point of only setting my APN to the correct value only when I wanted data enabled, usually just for an hour a day over lunch due to it going crazy downloading something. After a week of doing this the issue appears to have gone away and I am back to leaving data enabled 24/7 with an average of 10-15MB per day inc normal useage. From my orginaly post on this forum I was given the following advice to try and track down the issue...
http://forum.xda-developers.com/showthread.php?t=633169

change the first drop down to "network usage" and see which apps are using the most.

How I more than Doubled my Battery life with a simple toggle.

Greetings,
Guys, first of all, I'm no pro, this worked for me, it may not work for you, and its not the 'solution' for people who wish to be connected to internet 24/7.
- I have no Dataplan, Vibrant would connect and eat through my balance on EDGE/GPRS.
- I downloaded an app from Google Market, "Quick Settings" (search for it)
- Run Quick Settings and Turn off Mobile Data. It should show "Disconnected"
Basically, I did this with intention to save my precious hard earned money but the side effect appears to be that my Battery life suddenly has gone insane.
Before when I did have GPRS on, I would regularly check Advanced Task killer and kill apps in attempt to stop apps from connecting.
My use has been more or less same, I'm not a Power user, just take it to office, use now and then, and the battery would finish up in ~9 hours, 10 tops.
Anyway, here is the result

You can do this by just holding power then pressing Data Network.. or simply going into WiFi settings and disabling the phone from being connected from the internet.
Of course if you're using the phone without it being connected to the internet, a lot of power isn't going to be consumed. It's a smartphone, supposed to use the internet on it.
A tip I would recommend is to use SuperPower and it can do a bunch of tweaks to improve your battery (screen off; disables data.. things like that).
i dont have a dataplan either, but i DO text, if i do that, will it just turn off all communications like text and phone calls? I only use web when im at home with my WIFI.
I'm just wondering, why did you get a smartphone with no data? I see that you're not even using wifi. Why not just get a Windows 6.1 phone or a Blackberry or something?

I do have access to WiFi, tho I use it more at home and other places, less during work.
I dont have a data plan because there is only EDGE/GPRS available on it, no 3G *yet*.
So when I do want to check on something, I simply turn it on for a minute or two, check on my mails or anything else etc and be done. Otherwise, what was happening was, I'd get connected even tho when I did not wanted it to connect. It was costing me for nothing. I can do other syncs etc at home or 100 other places that have wifi.
I did not get Windows 6.1 phone or Blackberry is because Android > them both. I assume you know that already. + Awesome screen is awesome.
As I said very clearly earlier and I shall repeat it for you, this may be useful for people who have same profile of usage patterns as myself.
Please tell me that 19 hours isn't the best you got.

As for disabling the internet, i just check the box in settings to not use data. under wireless settings or something. I don't pay for data because no 3g in my area also.
Why not just put the Power Control widget on your home screen somewhere? The button between GPS and Brightness toggles whether you allow apps to sync on the 'Net or not.
IOW if you turn that toggle off you won't get email unless you launch your email reader, you won't get anything from the 'Net unless you initiate it.
Me? I just installed Onyx from Team Whiskey and I can go 3 days without worrying about my battery life if I'm just doing limited usage of the phone.

Solution to battery life issues (works 100%, guaranteed)

I love this phone and have posted this on several forums already. I want everyone to enjoy it as much as I do.
I switched from an IPhone 4 to the Atrix and I am really impressed by the device. HOWEVER, I was very close to return the phone due to poor battery life (in comparison the IPhone 4). The max I got out of the device was 14-16 hrs and the strange thing was that it did not make ANY difference whether I hardly used the phone at all or played around most of the time. Over the weekend I checked and after unplugging the phone from the charger and leaving it on the desk the battery was down to 70%.
By the end of the day on my IPhone I used to have about 30% battery left with all radios (3g, bluetooth, wifi, GPS) on and moderate use. With similar use and GPS off the Atrix hardly made it through the day. I read several suggestions and wanted to share how I increased battery life by almost 100%!! Like mentioned earlier I was puzzled that even in idle status there was a 10-15% drain. The only logic explanation was that there are services that continue in the background and drain the battery.
1. I think the absolute biggest battery drain is to enable wifi triangulation for location services. The fact that the pop-up window states "...Collection will occur even when no applications are running." should have made my suspicious. I have noticed that enabling the GPS does not have any significant effect on battery life as long as you do not have any applications open that use that radio (like maps). Obviously I disable the wifi option in location services.
2. Root your phone and download Titanium Backup PRO. Disable all Motoblur services. I do not use any Motoblur widget/services (no facebook, twitter and so on) and am happy with the native gmail client. I literally froze allmost all of the motoblur services as well as other services that may use data services in the background (news, weather services).
Following link gives a good overviw which services can be disabled without any problems:
Death-Force • Thema anzeigen - [TIP][Tutorial] Freeze Motoblur for more Performance and RAM
3. I haven't really found it helpful to use setcpu. Whats the point of having a ferrari and driving it at 30 mph?
Since making those changes I have seen a significant increase in battery life. Using the gmail client, bluetooth+GPS+wifi+3g on, screen set to auto-brightness and mdoerate use throughout the day I make it easily throughout the day with the battery indicator showing in general 30-40%. I think step 1 made the biggest difference. Again, this phone is just amazing and I do not miss my IPhone at all!
No way!?!?

Because you don't want your Ferrari to use up gas while you're not driving it?
With SetCPU, you can set a profile for it to throttle down several hundred mhz whenever the display turns off. I find that even background services like Pandora can run perfectly fine even when that dualcore "ferrari" of a machine has the display off at half the ghz.
Using setCPU alone, I feel like me battery life doubled. I recently froze motoblur in its tracks and only provided minimal increase compared to just underclocking it.

my trolling = quotes and screen shots of Dumb and Dumber.
its amazing how experiences vary from user to user. i had installed setcpu the 2nd day that i had the atrix and didnt really notice a big improvement (with it properly set up to save battery). i froze the blur settings and the weather widgets and can easily get through a heavy days usage. i find the atrix is at least as good, if not better when it comes to battery life.
i leave the wifi and cellular location option on and my battery life is great. i dont have widgets or apps running in the background that need my location and i even say no when google asks for permission to use my location for better search results. disabling this feature would make a big difference for people that use location aware apps often but i find it takes far too long to get a good gps lock when using maps if this feature is off.
as long as you are happy with your battery life, thats all that matters
Never used setCpu on my phone. battery lasts for awhileeeeeeeeeeeeeee!
setcpu is not necessary the cpu automatically throttles down when not in use, the phone doesnt run at 1ghz all time...
ive noticed with the atrix you need to turn off gps when you are not using it or it will still be on even when no apps are using it. my captivate used to turn off gps when i exited an app that was using it. im not sure if this is the case with wifi too.
After playing a long time with phone I found synchronized apps like talk, gmail, take up most of the battery.

battary problem?

Yes you need to update your ROM, it's quite outdated now but I don't think that's the issue. What about your battery drain in Airplane mode? Use Current Widget and see how much ma battery drain it is, mine is 2ma on airplane mode, 4ma with data and phone on, and 5-7ma with Wifi on.
Also your battery may be at the end of it life - they don't last for ever
Do you leave BT, Wifi and internet always on? that will produce the effects you are reporting on a battery past its best - or a cheap poor quality replacement (he says from bitter experience)
not about the battery..i have a new one, does the same thing
ill download the app you told me about and see how and what thanks

- with internet(3G)
-without internet (airplane)
as you can see, in that one minute of ONLY being on my home screen...batt went from 100 to 98...which as you can think (like..1minute) is quite fast and this is by not doing anything...no browsing etc...just downloaded the app and put it on my homescreen :/

No, you need to lock the phone then give the reading when the phone has just been unlocked. This will show your battery drain on standby. With screen on the drain you have is very good actually. I think your issue may be battery calibration, search on the forums for how to do this.
i downloaded that app batterycalibration and i put my batt too 100%, pressed calibrate and pulled the loader out, its taking ages cus im not using my phone, currently its on 65% but i hope this will solve my problem!
ok it has been drained too 0% and went off....now what? i justr started it up again..shall i delete the app or what..?
Do you have any apps that are doing a frequent sync cycle that you may not be aware of? Facebook and Twitter come to mind. Have you also tried to go to the hidden phone feature screen and select GSM Auto PRL for your phone? Using the default WCDMA Preferred uses more battery in standby. Go to your phone screen and type *#*#4636#*#* and then a Testing Page will come up. Go to Phone information and look under Set preferred network type: and select GSM auto (PRL). I am using a two year old battery, Tytung's NexusHD2 v3.2 kernel r13 ROM with WiFi on, Bluetooth off, GPS off using the GSM auto PRL setting and just got 6% battery drain over 9 hours on standby for comparison.
Please have a look....
Hi,
I am using same Nexus ROM
But getting good standby battery life....
Maximum Standby Battery life I got was 19 hrs.
Please install SetCPU and Juice Defender.
Please find this thread to have a clear idea.

It shouldn't. By 'internet' could you please specify? Do you mean that WiFi isn't working, Mobile Data isn't working or the actual Browser app isn't working? Also, I assume you've tried checking in the settings that you didn't accidentally disable data?

[Q] About WP7.5

Hi guys, just a quick question.
Which Windows phone 7.5 mango rom is best on battery life?
I'm currently using Pdaimatejams V8 VERSION of his wp7.5 rom, and the battery life on that is terrible. 8:30am to 1pm and battery is dead .
Advice on this would be nice as these roms are huge and take ages to download, so manually checking one by one would take years.
Regards,
Not as simple as that mate, they are all more or less the same ROM.
you have the defunct BTTF line which was complicated but by far the best overall ROM with the least problems
then you have Ultrafruit Clones
the really killer on battery life comes from the radio your using and any live tiles, also BT and Wifi can kill it pretty quick too.
in short try the 2.12 hardware radio ROM and the 51t software radio, the hardware radio can be flashed whenever but the software must be installed when you flash the initial ROM.
With those you can also try the camera trick, which is tap the camera button, put it in to video mode, let it auto focus then tap the home button.
its thought that for some reason the camera doesn't stop focusing or something like that unless you do the above, loading up the camera again will mean you need to reapply the fix
anyhow, so make sure you have no background tiles killing you, your running those radios, and you have done the camera trick, all with BT and wifi off as much as possible, and it will last a day with heavy use.

Right thanks for the tips! I had 4 live tiles, moved them.
Although i'm not quite sure what you meant by the camera trick?
Say i've done a fresh boot of the phone and not opened the camera app since, will that affect the battery life?
What's the camera trick meant to do exactly and how does it increase battery life?
Thanks for your response though!

well you need to remember that this phone was only a test phone for WP7, it never had proper drivers made for it, hence some of the issues.
if you have the 51T soft radio then you can do the "camera trick"
I don't think there is any real answer (feel free to correct me folks!) to this other than guessing but I think it goes along the lines of, the camera even when off or not even ran that session can continue to focus, which eats up the battery, its like leaving the camera on. by opening the camera, then turning to video mode, then let it focus and finally tapping the home button, it seems to dramatically reduce the discharge rate, in some cases to as low as 2-5mA
Now to be honest that sounds very low, but I guess if you turn everything off and live in a good signal strength area you may get that., ive not had it lower than 10mA, before the trick it could use anything from 30mA - 80mA for some reason it can jump up to 300mA, this is all in standby mode, putting the screen on with it set to high will zap your battery, the backlight settings are next to useless as well so its worth turning off the backlight if you can. I think the choices are, Burn your eyeballs out, wheres my sunglasses and finally Off, auto doesn't work.

battery life is subjective...it depends on the types of apps you have installed, their use of wireless services, your personal usage habits, etc.
Yea we already established that, but what is not clear is why it can go on a melt down and drain the battery very quickly for no apparent reason one day to the next. My theory on that is that ita not fully charged. IE. its half full but reporting full, thus it may appear to drain twice as fast

what day to day melt down? he only described one day's battery life of 6 hrs of use. 6hrs is not a meltdown.
it's an issue with the rom. if you READ the v8 rom thread, the v8 rom has lots of power issues. i've read many posts complaining about the poor battery life.

I've only described one days, although for this entire week it has been pretty much the same. Only lasting around 6 hours.. and are you suggesting it is Pdaimatejam v8 that's causing the immense drain? Perhaps I should try this rom: http://forum.xda-developers.com/showthread.php?t=953078?

i'm not suggesting anything. just conveying what other users have posted. you've posted to the v8 thread and you've seen all the posts about battery life issues since v8 was released. if you like pdaim's rom...why don't you just flash v7.9?

I see you've not change in the months since our last encounter.
Im running the V8 as I have been running just about all his updates and there are many, as well as HD2s, xbmods and even the Ultrafruit original that this comes from, the issues are the same on all of them. But If you care to read and follow all the information available in here you will see that its quite common for the HD2 running WP to draw ~300mA in standby, that its a huge amount of power to draw when its off and would empty the battery in 4 hours, without even using it.
when it comes to battery life, nothing is clear, however we do know that it doesn't always charge the battery fully, we do know that it can incorrectly report the available charge, we do know what despite devices using identical ROMs some folk can get <7mA in standby, others get >300mA in standby.
In short its a mess.
If you have an external charger and spare battery use it, it will help with half the problem, high current usage can be down to several things and probably many more that we do not know about, all things being well, if you use your phone a lot, use an external charger, make sure you have good radios for your area installed including the 51T soft radio an then do the camera trick, you may get a working day out of it without issue.
Thats with a lot of usage, making calls, BT, excel, music, 2 email accounts set to push etc

This is a meltdown. Overnight, no wifi, just sleeping. Tried camera trick. Nice rom and my first try at WP7.
I call this a fail.
Back in ICS now.
Sent from my HD2 using the power of ICS
just reminding, there are some problem with HD2 wp7 battery indicator which always shows wrong battery percentage...
altough it shows 0%, you still can use it for several hours....
try to change the radio SW and HW, and do camera trick...

ok, there maybe some problems with the battery indicator, but for sure it was deader then a dead thing. after pluggin in and restarting in android it was on 1%
i had what seemed to be the best radios and tried the camera trick.
but... apart from that, the phone was asleep (or pretending to be) with wifi and bt off.
