[Q] Display killing battery life - HD2 Android Q&A, Help & Troubleshooting and Genera

Hey all,
Quick question - for some reason I have really dodgy battery life in any of the most recent Android builds. This includes the Sense HD and the SuperRAM builds, with both recent MDJ & Hastarain Kernels.
If I leave the device in my pocket for a couple of hours, in standby, the "Battery Use" claims the Display is the primary cause for my battery use.
Just looking at it now, Android System and Android OS are both on 12% and the display is at 57%. That's after the display being mostly off......
I've tried three ROMS, including VBN's Android build, an official 1.66 HTC build and an official 3.14 HTC build. Furthermore, I've tried the 2.15.50.14 and 2.10.50.28_2 Radio's, both recommended for good battery life.
Any ideas?
Thanks
Jon

I am wondering the same thing. I am running darkstone hd2 froyo v3 with hastarins 8.5.1 oldcam kernel, everything runs great but it says display is killing my battery. If there is anything I can do about this I would really like to know.

Phew, it's not just me then! If I could be bothered I'd dig up an old sense build with and old kernel and see what happened. However I can't remember which one worked best as I change my ROM on what feels like a daily basis!

I have been using this as my daily build but I really wish there was something I could do about the battery drain. If it is something about the phone that I can't change or if a different kernel or something would help, I wish I knew. Any help would be appreciated.

it's not just you indeed, it's everyone there's at least two threads already about this.

Well, I dont really think its killing my battery life, however i did notice that its lower than when running winmo, I checked the settings and it says display is using 60% of power, I didnt really think anything of it as i guessed the display is easily the thing that requires the most power. So perhaps I have this problem too? I dont really know
Winmo I would get a day, perhaps a day and a half if i was lucky, android i get a day.

That's the thing you see, if the display is off for 2 hours, on for say 3-4 mins while I check my e-mail, it's still at a really high figure. Yes the display causes battery drain, but no where near that much.
I wonder if it's purely a kernel thing??

I only get 5% on my display battery drain.

I've noticed it depends what Android rom your using. The issue for me is either the Android System OS is using 60% & over or the display is using 60% and over. Either way the display or the system is the battery eater in my case lol.

What eating mine is cell standby and wifi, both 35-40% while android system is only 20% and display is 5%.
Sent from my HD2 Droid using XDA App

My display always takes up more than 60% of the power usage, but I have had builds where it's reported very low, I don't pay much attention to that anymore, they're probably not that accurate.
I did ran a quick test the other day of battery usage in winmo vs android. In standby both android and winmo were about 3-6ma. On the dimmest setting with no app running, winmo used 78ma, and android used 95ma, so it's a little higher, but not extreme.

I'm running at a crazy 67%...
For the heck of it, turned off all radio, left thephone @ 70%. Came back 1 hour later, tells me this percentage and the phone is at 63%...

Weather it's the Cell Standby, Display, Wifi or the Android OS, something is always taking power. If your phone drains completely in an hour or a day, the battery usage is just telling you what is drawing the most power percentage wise. 3mA or 300mA, it accounts for 100% of what's being used,screen off or not.

My android os only uses like 5% maximum, display is usually 60 though

Guys, you need to correctly interpret the percentage values...

Android on hd2 battery life

Hey guys. I'm a bit new to this, and I have a few questions. 1. Does having a faster microsdcard worsen the battery life of android running on an hd2? 2. With set CPU clocked back to 576 MHz Max 245 min, and all the settings toned back, I barely make it through a days use on my nexus one 2.2 build. Is this normal? Does battery vary greatly from build to build? Is there a build known for good battery life?
Sent from my Hd2 using XDA App
Android builds will always use much more power than WinMo, reverse engineering the drivers is not ideal nor efficient. Some builds use less power than others, best try a few with the current widget installed.
This is a thread on SD card power, I'm not sure it makes a huge difference. If you check the power usage app you will the OS is using 2 or 3 times the power that the screen is - this isn't good for battery life.
Hi lads, iam new to this myself I got my hd2 about 2 weeks ago and havnt had out of my hand since.. the only changes I have made was download hspl3 & flash radio 2.14 and I am currently running darkstones froyo 2.2 and I love it.. the only prob I had for my self was battery it was eating it.. when screen was off I was getting around 168ma and using phone was was up to about 600ma.. after about a week of searching I found out a few things and now I get a full day wit heavy usage. I downloaded setcpu,advanced task killer,green power free,changed a few settings on my phone and now I have a battery tats just as good as running WM.. ill get the exact settings up for u later if u want... hope it helps
after doing a task29, i loaded "vbn reloaded" (minimal winmo rom) ;
use EBL android loader and load mdeejay EvoSense 2.0 revolution ;
using "currentwidget" my battery usage is only 7mA idle with four email
accounts getting updated in the background.
Been using android as the (only) daily OS
z
ps just did a rm /data/system/batterystats.bin
need to see if it charges to "100%"
if only battery usage GOES DOWN WHILE ACTUALLY USING ANDROID,
that would be penultimate
(ultimate obviously is NAND boot )

Hello to all, iam using the android shubcraft version on my hd2 and i cant charge my device 100%. It stops on 85%. Did you guys have an idea??
Sent from my HTC HD2 using XDA App
I've been testing 2 different batteries fully charged with phone off. Using current widget they get the same readings about 7ma with screen off and average 200 on. One battery drains at about twice the rate of the other. Im pretty sure one is defective. I've cycled both to make sure. Also running on wm I get the same experience. If your lucky enough to catch a battery problem in the first 3 months of purchase from t-mobile they may send you another like they did for me.

heres a good thread on conditioning the battery
http://forum.xda-developers.com/showthread.php?t=827355
as far as sd card speed, a faster card will use less system rescources due to faster read/write speeds, ie: the cpu is under less load for a shorter period of time.
faster io performance = better battery life.
side note, underclocking to far will hurt battery life. this is due to it takeing longer to complete tasks. so if your like me and do a lot of turn the screen on, check some thing , turn it off, then the longer the screen's on the more your draining it.

Batter Life!!!!!!!!!!

Okay I am now running an Energy Rom, still every build that I have tried, the battery drains so fast!! It is almost unbelievable. I can not get a days worth out of this thing, I have turned off background data, and everything, and it still the battery drains like crazy! What is the point in having Android on this nice phone, when the batter drains too fast, you can barely use the phone? I have tried builds that include Kernel 8.5.1, still battery drains.
Download current widget to see your mA, I thinks that is battery voltage...what radio are you using and WM rom?
With chucky lite, radio 2.12 and froyohd2, if I don't play angry birds my battery still last about all day... And around 7mA in stand by.
I like the Energy Rom, can you give me a link to the FroyoHD2? Also I heard there was a Froyo with no sense ui, but I can not find it. My Radio is working just fine, I have 2.12.50
The answer to this question is all over these forums. 90% chances are the issues are between the 4.2" Screen and You.
With the right settings/configurations, you can get pretty damn good batt life.

[Q] Battery drain

I recently monitor my battery drain on MDJ Revolution HD 2.2 and want to check with you guys if they seems ok to you?
When phone has no applications running in background, freshly after boot it uses 3-5mA with peaks from time to time up to 150mA, this means that it consumes around 1% of battery per hour.
When phone has few applications running in background (more real scenario) it uses 5-7mA with peaks up to 250mA, this means it starts to consume around 2% of battery per hour.
I have never measured those values under WM but I can recall that phone used 5% over night (7hrs), it is less then NAND build I’m currently using.
Is this normal for Android to consume more power then WM?
Will battery format and delete of batterstat.bin help? If yes, can some help me with finding it? I am using Astro File Manager but if I go to folder /data/ it says it is empty, do I need to delete the file using terminal?
Thanks
I can agree with your findings: my drainage also seems to be like yours. But there's one strange thing I can't follow. After receiving a call or calling, my drainage increases from 3-5mA up to ~60mA in standby?! Does anyone know a solution therefor? I've already compared the processes running before and after calling and couldn't find any irregularities...

core droid evo v0.8
i have this problem on MDJ's CyanogenMod 7 v. 1.8, too.
on older builds i had it, too.
tested a few things, but nothing worked for me.
as said above the drainage after calls is fixed in every new nand build. so end of thread i would say
I was on MDJ Revolution HD and haven’t got any issues with battery drain after calls.
Now moved to MDJ Super Light 1.0 which has lower battery drain then HD, around 3mA in standby almost all the time, regardless any applications running in background.
That is not bad but still higher than WM roms
As i said in my post. I have this problem with newest mdj build, too. So, for me this thread could be usefull

ive read that Android as an OS aint as power friendly as others. My friends Desire HD only just about lasts him a day on average use. My battery lasts just as long as his does and his is a native Android phone so im pretty, happy although it did last longer in Winmo.

Oke, ill take it back , most new build have fixed the problem. Try the Rom I'm using, it has this problem fixed. And the Rom is 90% stock desire. I highly recommend it. Also, maybe you don't have the correct radio? But then again I'm not a pro just a guy who likes to read forums :3

With Clean Desire v.0.3.1 I have horrible battery life. It's like stuck at the 60mA, think it's that call bug or something similar. If you study usage history, cell standy is consuming like 33% of the battery, and phone inactive 32%, the display is at 2%
There is something rotten in the kernel. Turning of GPS, Wifi hell, what ever, does nothing to improve it.

That is why I stuck to the v0,2 most stable for me 3-5 ma with data on. And no problems as far worth noticing. Do make sure you have the best radio, I have 2.15.50, and seems to be best for all nands I've tried.

Can you confirm that there's no notification bug on v0.2? I switched from DFT because PRJ supposedly had it fixed but I'm using v0.3.1 and I still have the same thing, if a notification remains Unread it drains 60mA until it's Read --- is this not the case for v0.2?

i only know that the spike of 60ma after calls had been fixed. i didnt noticed the unread notification spike (cauze I have my phone on me 24/7) so i will read the notification within 3mins orso. so i have no issue with that.
but the battery drain is really good it this build. for me personal, no errors at all. only the unlockscreen sometimes freezes but then u wait 3 secs and its good again. but every hd2 is slightly different from eachother so you might have an other experience.
:3 but ill still recommend the prj clean rom

It's a great rom, it's DFT without the bloatware and I think purely Stock Roms are the best, unfortunately...I get the 60mA bug and it drives me crazy lol. I'm a extremely heavy user and the extended battery drain makes my days that much shorter =P

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

[Q] Battery life very bad on CM7

Hi everyone,
I have a big problem of battey usage on Android...
I flashed the NexusHD2 rom in a first time and i realised the battery life was very bad ! (I lost 3% for 5 minute of use !)
I flashed the famous Typhoon CM7 rom and it's the same...
My Radio is 2.15.50.14 and i use CLK.
Thanks for your help
Try a different kernel. That helped in ICS, so after some trial-error you should find a good one.
Sent from my HTC HD2 using XDA
What kernel is the best for it ?
I use Hyperdroid w/ seader r9 kernel. I get pretty decent battery life with it. But you also have to remember that the HD2 is a bit older so it has a smaller battery and less power-efficient parts.

Agreed, i flashed STOCK Windows Mobile 6.5 from T-Mobile and the battery lasted exactly the same time as with Android on it. I found that the ROM/Kernel combinations only matter a little. The phone alone has horrible battery capacity.

A bit?! Lol that would obviously help a lot. I'm not quite sure how accurate CurrentWidget is, but in terms of standby battery drain I get 5ma drain with wifi on on my phone. On the same settings on my Mum's Desire S she gets 26ma. However she gets great battery life, which I would only guess is due to the larger battery (and the fact that she barely knows how to use the phone, so the screen isn't on very much at all).

I use batterymonitorwidget pro. And i get around 5ma with wifi and cellular on.
Try using an app called JuiceDefender - it works really well at extending battery life. It basically lets you tweak loads of options to do with data and syncing, so you can have it set that data doesnt run when certain apps are open, or data is off when the screen is off, etc.
There's an ultimate version available, but it is £4.99 from the play store. But I guess that'd be cheaper than a new battery?
The same problem occured to me a few weeks ago. I have been using HyperDroid-CM7 which worked quite decent for 5 or 6 months and had very good battery life. ABut a few weeks ago suddenly the battery life became to awfuly decay, wasting 20% of the energy for idle hour instead of the normal 1-2. I changed the rom to the NexusHD2 ICS port and the battery life slightly improved but rhe problem stays the same. Could it be because the battery itself is broken or some software calibrations are needed (I haben't done any for an year since I bought the device)
