best battery life???

what roms / radios will give me the best battery life. currently running ahens latest rom with radio 2.08.50.05. battery life is good, have used nrgs roms in the past and they seem to drain my batt within a day of hardly any use.

2.09 radio seems best, as does 1.72 base and 218*** WM builds. look for roms like those.
Laurentius's ultimate power has great battery life. But most are ok for HD2. There are very few stinkers, and most battery life issues are due to 16GB cards - avoid roms with the documents/e-reader tabs to be sure of better battery life.

does a 16gb effect it that much because i am using one of those!
thanks for the tip!

I would think that it might be an indexing service that are doing this powerdrain, if this is the case - Maybe killing indexing service on SD card would improve battery performance ?

that would mean that EVERY sd-card drains battery?! or is it ONLY 16gb?

Reading and writing data on the mem card will use energy... if it's idle though i don't think it will.
shouldn't the indexing be done on only the first boot if it is done anyway?

There are quite a few people complaining about battery dain caused by the memory cards.
The most simple test is proven to start the phone without a memory card. is it better then reformat the card in the phone. copy the files on it and try again. If that not works search for corrupt files on the card. especially music.
the indexing serviceisgion wild on some phones. shutting it down solves the problem.
use the search of the forum on these things and you will find quite a few threads about this subject

Mem cards are all power hungery especially if you have your apps installed to them. Internal memory is more efficient, faster and uses less power.

+1 ... this is the only difference for me till now

On Radio 2.09 using Ahenf series ROM took off charge this morning at 7:15 now 13:10 and its on 73% which is a big improvement over other ROMS I have tried Also the icon set on this ROM, Stability and performance is great. Only downside Marketplace doesn't work. Which I don't use anyway

Using the setup in my sig
charge overnight, took out from charger at 6:15, did moderate to high web-browsing and turned on wifi router for bout 15 mins. Battery now at 22:10 61%

good shout i am really enjoying Ahens ROMS what is the radio you are using the long version 2.09.51.05 or whatever it is?

I've searched the thread but few people seem to comment on battery for Artemis whereas it always gets praised on Ultimate Power. Anyone using it?

Used this before Ahens ROM and in my experiance battery drained quite quickly. Lasting longer and longer now after two charges.

Using ultimate power 4 and can get 3 days from rom with moderate calls

Using 2.09.51.03_2 still running over 25 hours now used for calls about 1 hour, 70ish texts, 20 mins of GT2 on FPSece over 1 hour music playback and about 45 mins of internet on 30% still

just remember that roms like energy's will run down more quickly because the backlight is set so high.
Once you reduce it to 40%/60% battery/external things DO even out. But even then 576MB rom will use more juice esp if you load the memory up.
The more you use the device, the less you will notice differences - because use is use no matter how good a rom is. It's in standby where the tweaks shine.
I personally found Artemis < Dutty's HG < Energy < Ultimate Power.
BUTBUTBUT - we're talking about a few extra percent overnight, or a little during the day. For instance from 2days of moderate use to 2days with a bit more left for the third, but not completely.

[q] battery life?

So i'm retiring my G1 today and picking up an HD2 tonight. I have done alot of reading about android on Hd2 and that the battery life performance isn't that hot yet. But nobody really specifies the range of battery life. i know it depends on use, but with moderate usage am i expecting to get 3 hours of like or like 12? i also know it will vary from rom to rom, but which one so far by user experience seems to be most stable? thanks for your help guys.

With heavy use I will make almost 3/4's of the day, and if with just light use i will get about a day and a half out of it. Im using darkstone froyo v3.1 w/sense
I cant really say if its the most stable because the only other one i have used is a MIUI which is pretty cool just doesnt havnt have facebook sync. the froyostone sense build I use is awesome, I get no black sod's or screen freezes, wifi, gps, 3g, music player, and youtube all work perfectly. I havnt had to boot back into winmo in 2 weeks now, and that was only because I had to inorder to upgrade froyostone from v2 to v3.1

I had incredible problems with battery life with the stock TMOUS HD2 SD card. After swapping to class 4 8gb sd, it's been very good, ranging from 3-7mA standby lasting about 24 hours or more on a charge. It's current 3:14 where I am, I took my phone off charge @ 7:00 this morning and I currently have 59% charge left. There's some sort of bug with android where I can only charge to 96% (maybe my battery isn't calibrated??). I digress.
Things to note with the HD2:
If you're getting a TMOUS I really heavily recommend replacing the SD card with a decent class 4 one, connect to an SD Card Reader on your computer (DO NOT DO IT THROUGH YOUR PHONE) and format it with 64kb allocation size on a FAT32 file system. That has finally given me a stable platform for Android with decent battery life after weeks of trying. Before this I got absolutely HORRIBLE battery life and stability. But yes, it's worth installing now as a permanent solution.

-If you've done the "full charge in winmo first then in android" tip, it should charge at full. I notice though, when you reach 96% it gets vvveerrrrryyyyy slow but still it gets full charge.

I had that same issue with battery only charging to 92% but after rebooting to windows and charging it to 100% and then reboot back to android I was able to now charge my phone to 100% with android. (see my signature for my build). Hope this helps someone.
I was only getting around 5hrs max battery life with normal usage, calling, texting and internet use. I just installed Setcpu and will play with the settings to see if I could maximize my battery life.

Hey
I have noticed the same charging problem, in winmo it works without any problem but in Android its getting very slow!
Just another question, to maximize battery life I installed SetCPU and set some profiles, like if "Display off - 384 MHz ..."
Nonetheless over night I lost 16% of battery, I dont know why?
Any ideas??
Does SetCPu needs root rights? Are they already included in our builds? (I am not quite sure about that point since I am not able to move applications to SD Card)

How long did you sleep?
Yes, it does, but normally, in each build there is something like a Superuser approval for apps that requires root. But there are events it wont work.
And most of the builds are rooted anyway, I think.
The thing with the App2SD isn't possible on this builds, because Droid runs of the SD I think and your data.img is stored there anyway, so it is on the SD (correct me if I'm wrong)
How did you set the priorities of your profiles in SetCPU? The profile with screen off should have the highest prioritiy.

Disable mobile data, and you would loose about %7 overnight. Disabling 3g is also a good idea.
setcpu needs root rights but all new kernels and builds are already rooted. If setcpu doesnt complain, then it has root. If you are having problems, update your su binary inside superuser app settings.

With NexusHD 1.2 I can get 1% drain per hour, so theoretically, 4 days on standby.
I'd say thats pretty good

Yeah, okay, when its installed on the sd card, thats fine, but I had today the msg that their is not enough memory on the phone, so I thought maybe its nonetheless on the device ...
confusing, I turned off the mobile data connection, i changed just ports, and etc...
Nonetheless I will give APNDroid a go and test it!
I hope the battery will last longer, since I have changed the priority off the single tasks!
I will tell you

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 )

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.

Battery - Android using 50%+

I'm using Mdeejay rEVOlution 2.3 ROM. 'Android System' is using 58% of my battery, Chucky lite ROM with most of the WM settings off, and Hastarin Kernel (can't remember which number). Is this right?

No, usually Display takes most of the battery. Might be a bad build or something, you might want to format your SD card and load a new version of android on it.

Cheers for the reply! I guess I'll crack on with it. Good job it's a Sunday, hey?

i have installed android for the first time yesterday. this is all new to me (flashing roms and stuff) but it all went ok. i have though noticed that battery life is poor. Firstly, i have searched the forum and noted that many users are stating what the battery usage is in mA. how exactly is this measured? is there an app? secondly, it appears the battery can be effected by what rom, radio etc is installed. if i was to try a different rom or radio, would i have to install android again along with all my apps?
thanks

i kind of have this problem too but it hink thats just how these early builds are.
Use currentwidget to measure mA.
My mA idle get down t 5mA, but I am still having some issues getting battery life that i think is acceptable

thanks for that. just tried the widget. lowest i get is 7mA

5 to 9 mA is great battery consumption at idle, I'm having an issue staying there, I bottom out one day at 3mA but then today my phone doesn't drop below 50mA at idle. Windows Rom and radios are important for it to run smoothly but I don't think a lite rom makes a difference over a full rom, when haret launches , is gonna keep anything from running on windows(so I hear) I've tried many many roms, and the vbn rom, which is a super lite rom, didn't perform better than what I'm using right now which is energy cht. Radio will keep you from having issues with the phone waking up,(bsod) I've tried a bunch of radios and settled with the 2.15, a lot of people swear by it!

Battery life WP7 vs. WM 6.5?

Hey guys,
I am considering switching to WP 7.5 from WM (default ROM) and was wondering, will I see any battery improvements or it will actually drain it faster?
Also, anyone tried Android 4.0? All I care at this moment is battery life and don't mind whether it's WM, Android or WP.

Hi!
Best batterylife you will get on this device is with WM. Find the right release (some of them have improved power management) and stick to it! You will NOT be able to find better battery-life with Android or WP...
/Anders

That's right. As far as I know, best battery life is with WM6.5. However, I'm really happy about battery life in WP7 (DFT Ultrafruit changing radios and other things). I make more than a day, maybe 2, but being careful about what I do, of course.

Maybe wm6.5 is better.
But I feel wp7 takes better pics.....weird...after taking 240 pictures of a book..the battery from 100 to 13...is this normal or power consuming?BtW,it's standby life can be as long as two days with some general use

Battery life w.r.t various ROMs are as follow
WM 6.5 (Best battery life) >> Android >> WP7 (Worst battery life)
WP7 runs constantly at 998 Mhz (One of the reason for high battery consumption) where as 6.5 and Android can dynamically vary from low CPU consumption to High as required.
Also in WP7 battery life depends on soft radio + hard radio combination.. For good performance with good battery life use 2.15.50.14 Hard radio + 5.50 soft radio.. For best battery life use 2.12 hard radio + 5.50 soft radio..
Trust this clarifies..

Very Low Battery Life...Please help...
Hello friends...
Recently I have installed WM7 to my htc HD2. I found that the battery life is very less.
I have read here that if we use the combination of 2.12 hard radio + 5.50 soft radio.
Please someone tell how to do so....?

Search the forum my friend, hardware radio is updated via the custom RUU, it does not delete anything.
Software radio needs to be built in to the WP7 ROM before you install it, changing this will mean a loss of everything
Now, whilst battery life is deffinitely less than WM, one thing i can confirm is that its not worse than android, the problem is that it doesnt always charge completely, so for example, it may say its 100% full, but its only half full, so it appears to drain twice as quick, or it might say its empty and its still half full.
It could say anything, for best battery life use an external charger. reboots during the day will help keep it reporting correctly. Tho even then ive noticed that it doesnt always work, some times you need to plug a USB cable in for a moment for it to refresh it.
In short, battery charging and reporting is all over the place, but once you get a full charge it actually lasts quite a long time with very heavy usage.

Personally, now that I've found a WP7 ROM that doesn't drain my battery in 5 hours, I don't notice a difference. (I'm now using pdaimatejam, BT on with -3 to -7ma drain in standby, Yay!).
Sure, WM will last longer. Sure Android will last SLIGHTLY longer b/c it doesn't run the CPU full speed when the display is on. And that is a clarifying statement to the above. WP7 does NOT run the CPU full speed all the time, only when not in standby.
Having said that, I get a full, usable day in WP7 with moderate use. I got just over a full, usable day in WM6.5, but I had to charge every night regardless.

Testing 2.12 now, thanks,
Now sure if estimated battery life is correct, before installing it said 5h, now 2h

also dont forget to try camera trick with combination 2.15/5.51

Is 2.15 better than 2.12 in battery life?

10h standby (mail sync on) with all the tricks on HD2 2.12, bad

you can dream.... but none updates for WP7 cant be increase battery life... only can be worse
seems your battery in bad shape or something do wrong... also if you play music few hours, play games, nothing strange if battery not least long...
with radio combination 2.15/5.51 + camera trick, with WiFi on 24 hours at day, my battery working around 30 hours with normal use

Hm, well, it said 2h remaining but still holds, another 6 and has battery left... No idea.
I will play with soft/hard roms after Tango is released, as now floashing and losing data for a month or two is pointless
Thanks!

I have actually had better battery life using Pdaimatejam ROM with radio 5.51T/2.15 combo than I had with Android or WM 6.5. Not exactly sure how but it is definitely the case if any of you want to try that

2.worse battery life,excellent speed=windows phone
3.good battery life and reasonable speed with freedom to do things that you cant in wp and wm=android
i prefer wp7 and sd android and i have to charge 2 times a day (ok i have 2 batteries and external charger so i change the old one and i am ready to gο) but i have a phone that i enjoy to use
