Hi.
i am using Touch HD with extended 2600mAH battery and lots of software but the battery barely last a day. i was hoping you could help me diagnose the problem.
configuration :
-duttys XT 3.0 using manila
-1 hour of talk time a day at the most
these are my main suspects :
-checking for mail on two accounts every half an hour
-S2U2 1.62
-phonealarm
-pocketbreeze new PB2
-touchresponse
i installed nueDynamicClock but i can't see any difference.
first of all, maybe this sounds normal to you ? maybe my device is defected ? i'm sure the battery is ok.
maybe someone knows a good battery diagnostic program...
any comments you have on any of my suspected software ?
thanks,
david
Try this, quoted from official HTC site:
My battery drains fast even without using Bluetooth, WiFi or GPS. Is there any way to check if it’s faulty or not?
1. Charge the battery to 100%. 2. Disable from running or uninstall any 3rd party applications. 3. Disable Bluetooth. 4. Disable WiFi. 5. Enable flight mode 6. Set backlight to maximum settings. 7. In the power management settings, uncheck any option that would set the backlight to turn off. 8. Let phone stay idle for 1 hour and check battery capacity. 9. If there is a loss of 40% or more, then this means that battery is faulty and needs to be replaced.

Thanks for that. I've been a little concerned with my battery life so i'll give that a try later.

well obviously this doesn't help me too much because, as stated, the battery last almost a day with full usage so this diagnostic will be a negative... but surely something is wrong. Thanks anyway.
didn't anyone have any problems with one of the above ?
Max battery life
Battery drain in almost a day is quite normal with most of the roms
exception, i flashed Black Pearls v2.4 rom and the battery is still 20 to 30% at the end of the day. myself satisfied with the performance of this rom...

flashing a rom just to check this seems like a overkill...
i was wondering about any diagnostic tools allowing me to see the consumption without waiting a whole day to compare, any on knows of any ?

Why dont you check the idle cpu usage when your phone is on but not doing anything. It should be 98-99% most of the time. If you get high cpu usage by shell or services then it is most probably phoneAlarm or other plugins on Today screen.
If you are using wifi, make sure you set it to off when standby. (Note: If you are using AE Button (mine is v2.63) and if you use it to turn ON wifi, the wifi will not go to sleep even in standby thus draining battery)
Hi friends
Is it me or everyone is facing similar hurdles like huge battery drain on roms tagged with the latest kernel 2.16.32.15?
I have tested many of the cooked roms and their battery drain is enormous!!
I get a reading of average 200mA and above! :-(
I use setCPU still no solution
Please help!

Do you get the average 200mA reading when the phone is in standby or when it is in normal usage?...In normal usage (browsing, gaming, reading, listening to music) is OK to have this kind of drain...if it's during standby, it really is enormous, but it has nothing to do with the latest kernel. I am using the latest Mdeejay Clean build and I have a normal stand-by drain of around 6mAh (3mAh when airplane mode is activated). I do not use SetCPU.
The huge drain could be because you are using an incompatible ROM/radio. Try to use the combo from hastarin's signature (this is what I am using) and have a look at his FAQs (the link is also in his signature).
On a dutch forum, some users warned me about a bluetooth problem with one of the new kernels. They used bluetooth and drained their phone in just a few hours. If you're using bluetooth, try a different kernel. If you're not using bluetooth, try rebooting a few times and check your drain with currentwidget (as mihaig11 said)
Hi, did you have a look here : http://forum.xda-developers.com/showpost.php?p=7949689&postcount=42
If you are using a build with hastarin's 8.4 kernel, then this could be the likely culprit. Upgrade to his 8.5 kernel or use mdeejay's 6.1 kernel. Seems mdeejays's kernel gives slightly better battery life but hastarin's kernel seems to have a slight performance advantage. Also use Exceller's auto boot app set to 3 seconds & auto boot and reset your phone. If you let WM/Sense fully boot you will experience higher than normal battery drain. Also, I've been experimenting with the Advanced Configuration Tool. Install it in WM and then enable all of the Power Management options from this tool and restart your Android. Seems to improve the battery life on all combos I've tried. I've used all the latest builds and I average around 3-9 mA in standby using these techniques. From my experiences, the single most important factor for better battery life is using Exceller's auto boot app to boot into Android immediately before WM/Sense starts. Hope this helps.
Been trolling the forums, for a while, and I am wondering.. what effects battery life the most.. type of windows rom? the radio? kernal? or Android build?...
thanks guys.

Operating system? Screen colors? Flashlight for movies or photos?
Battery - energy loss or charge? Age - recycles from deep discharge? Plugged for longer than needed? Air temperature or silicon cased? Temperature with heavy energy drain?
Not a simple question.

As far as software goes, the biggest killers of battery I've noticed have been push notifications and wifi. Turning both of them off almost doubled my battery life. I now have my emails synched every 10 or 15 minutes instead.
In addition to wifi and push, a big one maybe the biggest, which is often overlooked, is screen brightness. These big giant screens burn a lot of battery. Keeping it as dim as you can stand it will actually save quite a fair share of battery

I feel silly for not mentioning that one myself now
heres a funny thing i found, i replaced my Apacer 8GB Class 4 card with a Sony 8GB class 4 card. the phone use to hang with the apacer card.
the thing is, ever since i´ve made the change, the phone sucks up twice as much power.
Theres great ways to make your battery last here too:

Calibrating Android's battery read will allow Android to fully charge your battery, and if you have battery profiles in setcpu, then the app will scale your processor speed by a more accurate reading, giving you longer battery life. I did it on the couple of builds I use most, and it really does make a difference
And dont feel silly john, I sometimes take my enormous screen for granted too
Edit: hmmm maybe my class 2 is why i get good battery life, maybe a slower r/w speed sucks less juice?
well, i know all of the normal tricks.. like screen brightness, wifi off, email push...
i am just looking for a windows rom, a radio, and an android rom, to get the best battery life...
thanks again guys.
Have a look at my signature.
Data enabled, push every hour only 5mA in standby.
If it is in airplane mode it only uses 2mA most of the time. That's quiet good
From what I can tell, the single most important factor for better battery life is using an auto boot app, such as Exceller's, to boot into Android soon as possible. I set mine to auto boot in 3sec. If you let WM/Sense boot fully, you will experience higher than normal battery drain; around 60-70 mA drain in standby. Also, try installing Advanced Configuration Tool in WM and enable all options under Power Management. Have tried these techniques with pretty much every WM Rom and Android combo and average around 3-9 mA draw in standby with wifi, sync, gps and data all enabled. This translates to about a day and a half of moderate use for me. Also, remember that Sense builds tend to use slightly more battery than non-sense builds.
This method really works! The simplest way!

I have trying different things for some times as why my HD2 was always 60mA+ power drain but some others reported as low as 5mA in standby mode. I tried different builds and different settings but none worked. I almost want to flash to change my stock rom or give up the idea of using Android.
Thanks to you! Follow your way, I now only 9mA with my stock rom. A considerable improvement in battery standby.
Thank you very much.

my phone tells me power in mV how does this equate to mA?

It doesn't really, mV is a measure of state (what condition your battery is in), mA is a measure of change (how much power is currently leaving/entering your battery).
Download current widget, free from market, to track the current (= in mA)

Current Widget. Set it to update every 60 secs, and then leave your screen off for more than 60 secs, turn the screen back on, and check the widget.
Battery drain with screen off should be somewhere between 5-9 mA
Nice tips here guys...
My battery meter in the status bar looks about 60-70% full, but battery widgets say i have about 50%.
Does this mean that I need to calibrate?
I tried to delete the battery stats with Droid Explorer but it seems to be in read only? (It doesnt do anything when i click delete).
I guess I'll set up ADB and delete that way.
Also I seem to get better battery without LED me know, (why do i need this?)
Runnig MDJ revolution, 2.08.50 radio, stock WM ROM.

Just run terminal emulator on your phone and type:
su
rm /data/system/batterystats.bin
oh, you can do this on the phone.
Thanks bro!
I hope to see improvements as my theory that the status bar battery reading vs widget battery reading being so different = it needs calibration.
Edit
I am now using Exceller's auto boot, and the my draw peaks are waaay lower, but the idle has gone up! (60-80 now...)
Hi guys i have some serious battery drain on my new touch hd, last night the phone had 40% and this morning it was dead, this is with a brand new high capacity 2400mah battery, i have data turned off as well as the screen.
I am running stonehenge 6.5 rom with cookie home tabs.
anyone got any ideas?
cheers, thedexter
change rom
turning off the display and wireless connections is one way to save power, but still the battery usage can be easily estimated by having a look at the cpu and ram usage. i for one use the stock rom, and when there are no apps running in background, my ram usage is at 35%, given that you are using wm6.5 and cht, i guess it would revolve around 60-70%, so indeed, to save power, a rom change might be helpful.
thanks for the suggestions guys
flashed a new rom version and downgraded radio to 1.14 and battery life was about the same, then i followed the battery calibration wiki and charged the phone whilst it was switched off and my battery life is looking much better.
cheers, thedexter
Hi experts,
I have a HD2, running HyperDroid CM7 v3.0.1 (based on Android 2.3.5). I MUST have 3G/2G always on, as I receive push notifications from WhatsApp, CNN, WordsWithFriends, etc. Also, I have disabled all background automatic syncing for all my apps (confirmed by 3G Watchdog Pro). I am a medium-heavy HD2 user.
Currently, my standby battery drain is 11-15 mA (measured by Battery Monitor Widget). The original battery does'nt last me a day.
I had installed JuiceDefender for a week ... but, it showed no improvement in battery life (with customised settings, to take into account my above requirements). I uninstalled it yesterday.
Can I improve my battery life under these circumstances ? I need my battery to last about 3-4 hours more ... so, that I can charge it just once a day every evening. I don't want the extended battery with the ugly hump.
I had searched the forum ... but, could'nt find an answer for my situation.
Thanx in advance.
cheers,

Try a different kernel and/or reduce your cpu speed and governor (conservative) in cm7 settings.
My experience with the rom you use is that the (modified) kernel which is included drains a lot of battery..
Good luck.
11-15 mA is pretty high. Have you tried setting your phone to connect only on 2G? A big factor in battery life is also your signal strength. Do you get good signal everywhere you go?
If battery doesn't improve by setting it to 2G only mode and you do have good signal try another ROM. I recommend NexusHD2-Gingerbread V3.0

I need 3G for faster loads while working on my HD2. Signal strength is excellent ... alll bars.
Looks like, HyperDroid 3.1.0 is around the corner with the original kernel (as mentioned in one of the posts by a HyperDroid member). I will wait for a few days for the new version .... otherwise, I will check out NexusHD2.
