Battery have strange issue

Hi guys, from about five days my battery seem to work normally, it reaches 100 % when I charge it but when it arrive at 7 / 10 % the phone shut down with no battery. Is it my battery problem or may be I don't know a kernel / rom problem?
Thanks

its a kernal issue ..stop tripping my friend all builds have there issues , most are learning to live with it..but i have found a number of way to improve battery life ...like removing apps that run in the background that i dont use ..but this has been posted a thousand times , dont be surprised if this get closed quickly

So the battery level show in android isn't the real battery state..

yes some people have reported other issues..but i would suggest explorering the threads a little more

Update!
This morning windows and android show me the same battery status: 20% left.
I shut down the phone pull out the battery then I start- up the phone and now windows and android show me only 8% left.
again... This can be a battery problem or something others?

Sport, as already stated by Thatruth, its an issue with the builds right now, battery isnt fully finished yet and levels will probably be read differently in winmo and android. My own battery will only charge to 97% in Android (Mattc 1.5b) and charges perfectly in winmo (VBN Black RC6.2).
Calm down......

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?

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 )

it has a lot to do with radi youre using, i found this one really good, have good bttery life, 3g, hdspa, wifi, gps, mms and all working really good...

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??

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.

[Q] Why the battery consumption is high in Android ROM

I have HD2 with
1- windows mobile 6.5
2- ROM Prestige X
3- Radio 2.15.50.14
4- Android ROM Moto234_Incredible_Remix_V2.0
and I have turned of (Wifi , Bluteooth, GPS)
and I noticed the battery consumption is high in Android ROM, but in Windows Mobile very good , so what do you think the problem, and what about the solution

Some of this is due to the fact that android is still booting from the SD card

most of it is due to that the device can never 'sleep' or enter an idle mode. which is very low power. So the phone is always consuming power.
However with both of the android roms i am using i can go a full day with out charging with high usage.

Could be several reasons:
1. Your WinMo ROM may not be Android friendly.
2. You may need to boot into Android as quickly as possible using Exceller's Boot Loader (set for 3 seconds) and ensuring that the key lights are on when Haret is loading.
3. You may need to boot up Android a couple of times in Normal mode and not Hot Boot mode. This seems to be the cause for many people.
My TMOUS phone using VBNDroid RC3 ROM, 2.15.50.14 radio, Mdeejay Froyo Sense Clean 2.3 build and Hastarin's 8.5.1 kernel with stock Sandisk card can run for a couple of days with light use. I also have SetCPU and NoBars to help reduce the battery drain even more. I am seeing 3-5mA drain on standby with 150-300mA with WiFi and app use. How much battery drain are you seeing?

why did you post this here........ this goes in general or q&a
i mean... seriously..... read the forum rules and follow them......

I swear a huge percent of the threads being started in the past day were questions regarding my builds, which I don't understand because I am answering EVERY question possible in my thread as much as I can.
P.S. I replaced the Incredible build with the Evo build for a reason. One of them being, it's better on battery. Please from now on, ask any questions regarding any build in that builds thread, that's why we have them. If I can help you with anything please let me know.

Motoman234,
You most definitely do quick replies and great work. Checked your build thread and noticed you already answered this person's question. So I do not know why they posted the same question here and in your build thread, was there first in fact before this thread, so don't know why people do these double posts. Maybe the moderator could either move this thread to your build thread or delete it altogether.

I am having similar battery issues with my device. I currently have a tmo Hd2 w/ Energy rom winmo build using 2.15 radio and the latest mdj build on a class 6 8gb. With typical usage i.e. 30 mins in calls, 75 text, 30 min pandora, gmaps for traffic, 30 web pages like newegg or cyclegear, 15 actually read emails, and maybe 5 pictures. With this usage I am getting 6-7 hrs battery life if I leave the data and cellular line active. If I throttle the radios via airplane mode (its my second line) and use wifi for all connections I can get almost 2 days out of the device. I use setcpu but dont see a big difference in either case. Well just thought I could contribute some input. Thanks for everyones hard work.

first off your sd card (class 6) draws more power. and the kernel has a lot to do with it. these are all based off a new kernel. very different. get the extended battery its worth it
you could also try just turning off data connection, that way you still get calls and regular text, then you can turn on wifi to get everything you lost with data when you need it.

You guys can also check out an app called "SuperPower XDA-BETA" which is on XDA and also on the Android market. It has a ton of power saving features including turning off data when the screen is off automatically (much more than just this) just an example.
Here is the link to the development thread-> http://forum.xda-developers.com/showthread.php?t=807989

Did you try to use the super power app? For me it has made my wireless connection stop working. WiFi still does but mobile data hasn't worked at all.

Some ppl are not having battery issues which clear from following the relevant threads. Please try adjusting your WinMo ROM/Radio/Android Kernel/SD Card and you'll be pleasantly surprised. This thread should be closed or moved.

It worked fine for me but I didn't use it for long since I get plenty of hours out of my battery with heavy usage. It seems like the kind of app that works great for most but for some it doesn't.

296mA isn't bad when running using the phone. I have seen WAY over that in some builds.

I think standby powerdrain is now acceptable with latest build's/kernels..It mostly 3-8Mah...I don't think its much lower than that even in WinMo..because rated standby time for HD2 in ideal scenario (on which rating is done) is 480Hrs on a 1230mAh battery which gives ~ 3mAh standby drain..
Even During the call the drain is acceptable its mostly 220-250mAh with screen off...so a 1230mAh battery is going to give you approx 5.5 hour talktime which is again close to rated 6hr talktime of HD2 with WinMo...
The main problem is display and Android Apps...they draw huge power, and I think even Native android phones from Motorola, HTC etc are suffering from same too. I've seen Evo, tmobile touch 4g, droid x owners complain how their phone barely last 1 day with moderate usage and such...There's only one exception though i.e. Galaxy S which many people claim has good battery, other than than that i've not seen a single android phone of > 3.7'' display being praised for battery....

[Q] Display killing battery life

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

Consumption of SD and NAND Android

Right now, I'm using SD Android on my HTC HD2..
But it consumes more than 30% of battery power in standby mode for 5-6 hours...
and drains a lot when the screen is on..
1. I'm wondering that how much battery saving will do if I change it into NAND Android?
2. Should it consumes less power and stable like original Windows Mobile 6.5?
thank you

You won't get battery drain which will match WinMo if you use Android, but you certainly shouldn't get such high drain either. Turn off all connections, use JuiceDefender and SetCPU to minimise drain and install current widget to get a better reading. It should be around 7-8ma for an SD build. For me, that amounts to 1% an hour. Also, NAND has better battery life and performance, but bear in mind you won't have WinMo (although in all honesty I doubt this would make a difference )

No that's far too high. Which ROM are you using? Have you used SetCPU and JuiceDefender as I suggested? Also try killing all apps before turning your screen off.
