Hi,
can anyone explain me please why Android is so much power consuming on HD2 comparing to other Android phones or even WM 6.5 on same phone?
I have DL_Desire Installed an I can hardly use my phone for 15hours with normal use.
Why WM 6.5 last for at least 20 hours?!?!
The only thing that is different (about configuration) comparing to WM is the live wallpaper.
A task manager is also installed in order to kill unnecessary apps.
Thanks in advance
Well, if you're running Android from your storage card, then just reading the card all the time is extra work being performed by the phone as compared to reading from NAND, plus the HD2 isn't made to run Android, I mean it's ported, not native, so not everything is perfect. Plus live wallpaper means a little more battery uesed, and task managers use as much battery as they save, so you're not really getting much improvement (if any) in battery life by having a task killer running.
Plus another big battery killer the HD2 has that alot of native Android phones don't have is the huge screen. It eats alot of battery.
But the overall answer: Android is a bit of a battery hog. Thats just the way it is and the price we pay for the best OS choice. My advice is abandon WinMo, boot Android from NAND, find a good combination of ROM, kernel, radio, setcpu settings, and autokiller memory settings that gives you your best balance of performance and battery life. You should get a full day out of that easy and have some battery left over when you plug your phone in at night to charge.
android is more interesting than wm6.5...which will make you use your phone more frequantly...so...it will surely have a shorter battery life
For me, it's 1% or less drain on standby. 2-5mA
It will last for more than 20 hrs on normal use

That's about what I get booting from NAND. 3-7mA stanby booting from sd, but my sd build drains faster when I'm using it than NAND does, but in sleep mode, not much difference between the two.

my uptime is now 1d23h and there is still 40% battery.
This is with lite use
I think the battery life is great
I think it's 1% for everyone with any build... it's just the time to loose the % which varies
Ok, I go out... once again a useful post...

Is it just me or is the battery life horrible, I can barely go half a day without it dieing?
I have gps off, the brightness down, and kill the task's in task manager all day.
I did update my radio but have not tried 2.0b2
My battery has been getting really warm with the 2.1 ROMs. I have switched back to a 1.5 one. Is that just me? So, yea, haven't had great battery life.
I have been using AOSP roms with no sense so switching to this battery has been alot worse. But when I think about it I do not believe it has been any worse then when I was using 1.5 with sense. Cant wait to get a fully functional 2.1 AOSP
I've been running Fresh 2.0b2 today, with 8hrs uptime and 1hr 30min awake time I have somewhere between 60% and 70% left. I did flash the radio.
definitely sucking the battery down. even after wiping, radio and flash. could have different results from phone to phone, I'm more of a heavy user.
really? i been getting realllllly good battery life. i was BT music for like an hr then i gps'ed for like 20 min and wifi connected to gmote for 2 whole movies. my battery is at 70% right now and its been unpluged all day....i love this rom
try active browsing for an hour straight... sucks my battery straight to hell.

No real battery issues thus far. Make sure gps is off the settings are different in 2.1 I thought mine was off it wasn't. Also shut off flash until you need it. I use dolphin for browsing, no blue tooth, no gps and heavy useage with good battery results.
I came from a Pre which has horrendous battery life so perhaps my expectations are low but I go the entire day with heavy useage.
How do I turn off Flash?

Go to the browser settings and uncheck load flash.
Honestly, my battery life has been better since i switched to Fresh 2.0b. It's really hard for me to gauge actual battery life because I spend most of my time at work where my phone roams constantly. BUT as far as my phone roaming and just regular use it seems that my battery life is way better.
Hard to say. I want to say the battery life is lower, but I also spent a lot more time playing with the phone and downloading/installing apps since 'upgrading' to 2.1.
That could be what you guys are seeing too. You're just using it more without realizing it.
My battery is actually pretty decent.. I have more widgets and programs running than I did on 1.1, but the battery is defiantly tolerable.
This is a BETA ROM and Flipz hasn't even had time to mess with the power management side of things, so just be thankful you have a 2.1 to mess around with, that is almost fully functional.
If you use the power control widget and turn off everything; wifi, BT, gps, AND especially SYNC, i get good battery life.
With sync disabled it doesnt pull gmail or weather but id rather have better battery life and sync gmail manually
13hrs up time,
2hr wake time
Unplugged for 5hrs (according to the Battery Use widget)

So far I've been getting worse battery life with the 2.1 ROM. I was previously using Fresh 1.1 and got like 36 hours with a single charge. With the Fresh 2.0 ROM I get maybe 16-18 hours. I'm thinking of switching back to Fresh 1.1 until the new ROM is tweaked as I'm sometimes more than 24 hrs without being able to charge at work and I need my phone while at work. Great ROM nevertheless.
Hello everyone.
The answer to my question can probably be found by scrolling trough hundreds of topics and posts, I guess this is a reasonable topic anyway since it’s a issue that will be the main reason for many users about when or if they can start using android on their hd2 as the main OS.
Thanks to everyone who contribute and good job!
I would very much like to start using android on daily base, but for me the battery has only lasted a couple of hours.
I’ve seen people claim to have up to 10 hours of battery with moderate calls and radio usage.
Please post your experience about power consume with your android build and radio rom.
I'm getting about 7 to 8 hours before it's dead. so wish i could get more
I went to sleep with 80% battery. 10hours later I awoke with 0%.
However, I did forget to turn off Background Data, so that could explain the huge drain.
Either use SET-CPU, or what I use, JuiceDefender, This app (combined with the UltimateJuice Add-on) Gives me 2.5 X longer batterylife... It has a widget which actually shows you how much longer your battery will lasts. It also has schedule Data activation or Disconnection. And much more options, i really love it!!!
It is basically the same as SetCPU only with far more options and not as complicated!
hope this helps
My device lasts for about 24 hours, with periods of 15-30min excessive use..
I'm getting surprisingly good battery on my HD2 running Froyo V1 by darkstone, my radio is: 2.12.50.02_2 and I'm running Energyrom
I get about 1 days worth of battery on average use (about 30-40 mins of calls, 2.5-3 hours of wifi, 1 hour of gaming)
Yesterday I had wifi on for 5.5 straight hours downloading games and then playing the, in these 5.5 hours my battery dropped 50%.
Today I'm trying an overclocking widget that I set to have the processor running at 200Mhz while screen is off, and running between 200Mhz and 1Ghz when screen is on, I'll see if that helps with the battery.

So I notice that an hour on wifi surfing the web took about 20% or more of thE battery...even playing game doesn't do that to the battery. Anyone experiencing similar thing? Anyone with 3g, is data looking the battery too?
Just keeping wifi turned on is also drains the battery for me.
Check your screen luminosity.it is the biggest battery killer
I'm running the Moto234_eVo_Carbon_V0.3 build and I've noticed that even with the screen off and the phone idle my battery drains at a pretty good rate when compared to WinMo. Any fixes for this?
for me 3g/h draw much power than wifi, almost 1.5x-2x of the wifi surfing..
Screen brightness is easily the biggest batter drain keep brightness as low as possible,
Data connection will hog more than WiFi if you are in an area of weak signal and your device is constantly searching for a signal, when your at home or work using WiFi just turn data off and switch to only 2g networks, set setcpu to screen off 245 245

Screen brightness definitely hits it hard, then wifi and bluetooth, keep em off whenever you are not using them and of course apps running in the background, grab a task killer, if its not needed, it shouldnt be running or else it will use power.

Get "current widget" from the market to see how much powers are being used. While screen off, my phone only drain about 4~7 mA...
I just came across this. Super detailed analysis of battery usage.

3g draws much more power than wifi. If wifi is available use it over 3g. But like others have said, the screen is by far the biggest battery hog.

I don't see how the screen is the biggest energy hog. When I leave my phone uncharged untouched over night and it it displays 7mah on current widget, I lose 40% battery in 7 hours.

That's unusual...i lose less than 10% over night...even with bad reception in my room, that didn't kill my battery. Maybe you can try this to test it out. Fully charge before you go to sleep. The next morning, check your battery in setting to see what is using the majority of the battery drain during that period...this might help you find the reason...
If noting else is running, Cell standby will eat the majority of the battery power.

You need to reinstall new build and do a task29 and format your SD your battery stats are all over at 7mA you should see 1% per hour

Yes thats true, exactly the same in my HD2: 3-7mA = 1% an hour or less
Wow, I installed Mdeejay_eVo_Sense_v_2.3Revolution to see if this build helped on battery life. I charged my phone over night and had a full battery at 11AM (according to the meter) but by 7:30PM, my phone was completely dead. During this time, I had two 5 minute phone conversations and used GPS for 9 minutes. Other than that, the screen was not active and I didn't have WiFi enabled. Is this typical? Doesn't make running Android very practical on the HD2. This is only the second build I've tried but it's not looking very promising.

Something is wrong with your build. Try his newer build. They got a new kernel. If that were my habits, my battery would drop by only about 25%. You should install "current widget" from the market. It help you keep track of battery usage. On standby, most people and I got about 3~7mA. If you get a higher mA, that mean something is eating your battery.
Please give Mdj's New Build "Froyo Sense Revolution 1.6" that comes with his new kernel which is suppose to make battery last longer. Hope this helps.

i hope this enlightens you and yes wifi kills battery but it is not the biggest battery killer and wifi is more harmful to your battery life if it is not connected which means it is constantly searching for a network which sucks the life out of your battery.
I think the wifi modules on the new kernels (Hastarin > 8 & MDJ) are consuming too much power.
I usually got 5 ~ 8 mA in sleeping mode with my wifi turning on on the previous kernels, but now I got 8~60 mA and the battery status is showing that wifi is taking about 30% of the battery. Maybe this is because the 802.1n is enabled by default!
Which gets better battery life on HD2- Android or WP7?
android nand can get 2ma on standby and uses less overall

do you know the standby battery consumption on the WP7? I would like to know the comparision.
I have not tried Android in months (in fact since DFT released WP7), however, prior to that i could not achieve good battery times with NAND Android + downscaling + task killer etc.
Has this improved the past few months? WP7 i get a full day so i never went back really.

5-7 with the camera hack. Sometimes the phone randomly gets hot and stays at about 70 in stanby. Also while in use the phone uses a lot more power.
I use my HTC HD2 a lot, so the battery drains quite quickly. I'm currently using android 2.3.5 on Hyperdroid CM7.
The battery life is decent, but I can sometimes barely get through one day with only texting and web browsing.
For those who have used both android and 7 mango, can you please compare the battery lives? I'm thinking of making the switch if it means that I can get more usage.

I guess it's NAND Android? For me, WM 6.5 had always the best battery life but with the camera trick I get slightly better battery life in WP7 mango than in Android...
Atm I'm on WP7 mango (yuki/xbmod bttf) and I can get easily through a day (texting, surfing over wifi and some gaming)...
WM 6.5 was the best, but WP7 with old radio (2.12 without T) is near the WM 6.5 autonomy.
Android in 2.2, 2.3.2, CM7, ... was everytime to drainy to have a daily use. Just good enough to play whan plugged to a charger.
What rom do you suggest I use for best battery life?
Hmm, I'm using the Back To The Future Rom updated to mango including the cleanup (that one made the battery life slightly better)
I have 5mAh drain (after battery trick) when in standby and with moderate use it lasts 2 days. With heavy usage easily one day...
I started out with a HTC Touch Pro. Batt. life was okay
Then I got a Milestone (1): Batterylife was ... okay (1 day)
Then I got a Milestone 2 : Batterylife was similar to MS1 (about 1 day)
THEN I got an HTC HD2 and went for MIUI directly. Battery Life was okay also about 1 day. Then I started using SetCPU wich extended my BattLife ENORMOUSLY. I go from about 6 in the morning until about 12 in the night by HEAVY useage (BT almost all the time, PushMail, FB Chat, WIFI running, listening to music via AD2P all the time).
Then I got bored and decided to mess up my life - so I installed WP7. Took me 3 days to install and get unlocked. Don't misunderstand me: I love the OS. I think WP7 is great in means of style and usability. But besides BT-problems, and Market quality, I went back to MIUI mainly because of one thing: THE BATTERY. With BT running and WiFi on, worst days only got me 5 hours of battery time. Totally unacceptable.
As soon as BatteryLife is improved, I will go back to WP7!
I installed CM7 2.3.5 and Mango 7720, Mango has better battery life than CM7.

i have usually gotten better battery life out of the miui NAND builds than mango but I'm sure if its because i'm usually playing games on mango than i am on android
I'm having such a different experience with battery life. Mango was an awful drain. Camera trick (if I did it correctly) didn't do anything for me and it seemed impossible to gain a full charge while WP7 was running. Had to boot into Magldr to get a full charge. Just wasn't worth it for 6-8 hours with very light use.
Enter CM7 Gingerbread 2.3.6 NAND. Good to decent battery life.
If I could get Mango to perform the way all of you are getting it to, I'd love to switch back. I'm really learning to like Android, as I understand more about how it works, but I'd enjoy more of the WP7 experience.
So that's what I'm doing: record one second video in the camera ("camera trick")
And remember to do it after every reboot of the phone...
To get a full charge, try to use the battery indicator level fix:

(You don't have to do this all the time... just once)
Try it, enjoy it
Found out that part of my battery drain issue was my SD card. Though my Kingston 8GB class 2 "seemed" to be working fine, I realized the strain it was putting on WP7 after I upgraded to a PNY 16GB class 4. It's much faster now and the drain is much lower. turning off wi-fi helps too.
The only solution that worked for me amongst all the options (based on my experience)
1. Tried the camera trick - NOT WORKED
2. Followed the steps below - NOT WORKED
* Boot the phone to MAGLDR
* Select "Reset" option from the menu
* Phone reboots normally
3. Hard reset the phone - NOT WORKED
4. Charge the phone in magldr USB storage option - NOT WORKED
5. Finally, flashed the 2.12 radio, did the camera trick (not sure if its relevant). The battery life has improved dramatically. It lasts more than 24 hours and still running (26% left) - WORKED.
Follow the thread below to download the 2.12 radio
