I have a problem with battery on my hd2, i have used an android darkstone V3.1. My mistake was that I let my battery to drain completely while the phone was on android as I mentioned. I`ve turned on the phone, the phone went to native windows and I tried to charge it, but instead of charging I got a massage: battery failure!!!! ((( I pulled the battery off and return it and after that the phone starts charging like usual. After that I didn`t use an android, but, yesterday I let the battery to drain completely (this time on purpose) and I couldn`t turn on the phone or charge it!!!! (( The only solution was to pull the battery of and return it, and time and date was also messed up so I had to change it!
Any clue???
Thanks in advance.
I bought this Hero off eBay, and it was dodgy since the begining.
The phone had cyanogen, and was restarting itself occasionally.
So i wiped it, installed 2.1 and it got fixed, but now i have a problem with battery drainage.
Its insance, 10minutes-10% im pretty sure its not supposed to be like that. with or without wifi/3d turned on, its just riddiculous.
I borrowed battery from a friend, and that didint make any change, i installed latest update from the autoupdate in the phone and still its bad. I read somewhere here that its faulty email app that keeps on trying to sync and drains battery, how do i fix that ?
I did a full wipe, cleared cache and everything back to factory settings, with no apps installed it goes from 100% to 0% in an hour.
I downloaded 2.1 from some android forum, as i was unable to find one here (there are only links to 1.5 on the xda.wiki WHY?)
If you can point me to a proper 2.1 (or higher?) software to download that doesnt do this crazy **** i'll be happy as infant on crack.
Please help, here is my software information:
Firmware: 2.1-update1
Baseband version: 63.18.55.06JU_6.35.09.26
Kernel version: 2.6.29-063c4d24
Build number: 3.32.405.2 CL191507release-keys
Software number: 3.32.405
Browser version: WebKit 3.1
Try calibrating your battery it gave me a huge boost on my hero... went from getting 16hours day.. to about 30hours on a single charge!!
Every time you flash a new ROM you need to calibrate your battery. The battery meter in the OS (Android in this case) is generated based on the battery stats file.
Battery stats is erased when you flash a new ROM.
Easiest method of battery calibration when you're intending on flashing a ROM:
Ensure battery is fully charged according to the OS. Switch phone off, unplug charger and plug back in. Once light is green, leave charging for another 30 minutes (light goes green at approx 95% charge).
Switch on, flash ROM. Allow first boot to complete.
Shut phone off. Disconnect charger. Remove battery. Replace battery. Place on charge, light green, leave charging another 30 minutes, yadda yadda. Switch phone on, boot immediately to recovery. Wipe battery stats.
Boot phone up. Now would be a good time to install JuicePlotter. Use as normal. Do not charge, let the battery run down completely. When the phone shuts itself off, power it back on. Repeat process until it won't switch on anymore.
Remove the battery. Put the battery back. Turn the phone on. Repeat until it won't turn on anymore.
Now charge the battery on the mains to 100% while the phone is off, keep charging for 30 minutes after light goes green. Power on. Voila, fully calibrated battery.
The last part, run until completely dead and charge only needs to be done once in a while (this is calibrating the battery innards, not the battery stats)

hah, yea thats what i accidentally figured. phone was switching off, but when i powered it back on it had 30%.. and it was like that 3 or 4 times.
I ran it down completely and now am charging it till max, we'll see what happens. at worst i'lkl start your process from the beginning thx !
I diidnt know you had to do that. i've been playing with my G1 and not even once i had to calibrate that.. maybe i should
How'd it go? Any improvement on battery life?
it diidnt help I did what you quoted step by step and its still running down the battery like crazy :/ what else can i do ? im thinking of switching to 1.5 but thats just not progressive and my friends phone is running fine on 2.1, with the same battery even.
Edit: i've installed task killer and killed all the mail checking apps.. hope that is the problem
Edit2: it didint help at all, in 5 minutes i lost 15% fcuking hell !
I just switched to 1.5 and its still happening ! I using a different battery and its just as bad... why is this happening to me
ill try second to latest radio from xda wiki.. im running out of ideas,what else can i do ?
That really wierd... its not the battery if you have tried using different ones. Its not the ROM if u have changed it.
Have you tried disabling auto-updates? and auto-checks for emails. Which email client do you have? you should find the option to "sync-never" in the app settings.
Buying it from ebay is kinda ominous though.. was it described as faulty? perhaps you could contact the seller and request a refund is all else fails?
you can try using setcpu to underclock the cpu.
i have similar situation as you. before going to bed around 11pm, it showed 50% left, turned on airplane mode, then in the morning around 6am, phone was powered off.
now it has been 2 days, still have 20% left.

Did you ever take into consideration that some part of the hardware might be damaged?
Devices that got water damaged, sometimes show weird symptoms as well:
- They still boot up and seem to work well from the first sight
- The battery drains very quickly
- Some of the peripherals are not working stable or not starting up anymore (e.g. wifi, bt, gps)
- Other crazy things might happen as well (e.g. random reboots, backlight flicker, etc.)
So you might have a look at the mainboard. Red stickers indicate water damage!

Yea but if it were damaged would it show 50% battery after restarting thinking it had reached 5% ? i dont have the tools or will to unscrew it.
i paid 100 pounds fo it, the normal price of a used hero, but the auction said "phone restarts for no reason" and they do not accept returns, so im propably screwed :I
I had an old blackberry 8300 curve, i had it in the bathroom while i was showering, got too moist, turned the detection pads red but phone seemed to work fine after i dried it out. But the battery went to crap progressively in the manner. I would charge to 100%, take it off the charger and maybe an hour it would say less than 10%, do a battery pull and it would go back up to maybe 80% and last maybr another hour and keep doing that till it would normally drain on top od the numerous reboots i would be doing until eventually it would just drain and die.
Sent from my HTC Desire using XDA App
Can dead pixels cause this ? i have like three.. but then again why would it show 50% after restarting from 5%..
the thing is its not draining the battery, just registering it wrong
Any updates on this? Any resolution?

sorry mate i have tried everything unsuccessfully and returned the phone to the seller.. dont tell me you bought it ? (london)
No, but i have a samsung galaxy tab and experience similar symtoms. It does not bother me too much, the battery life is still great. Just the percentage is off and i need to restart from time to time.
I read similar complaint from droid x forum too.
This method is suitable for hd2 SD Android, not test on NAND mode. If you encounter problems as the standby battery consumption(50+ma), you can try this method to solve:
If you reboot android and monitor the standby battery drain is 3~5ma,do not happy too early and think that you get a good android rom, because after reboot,it will likely become 50+ma;
If you reboot android and monitor the standby battery drain is more than 50ma, do not despair, don't think that this version is so bad and you need to replace another immediately, because you can use this method below to fix:
Steps:
1, reboot WM, don't hurry, wait 1 minute, let's WM fully reboot, especially some softwares installed on SD but need to run when reboot. press the power button to turn off screen(not shutdown mobile), open the back cover, remove the TF card, the screen will light up, tap the power button again to turn off the screen (not shutdown), wait 10 seconds, insert the tf card, the screen lights up again, now boot android and monitor standby battery consumption, 90% under 10ma ----- In short, that is, before boot android, pull out and plug in TF card;
2, if fail, you need pull out and plug in battery before reboot WM, then repeat the above steps;
If works, please say thanks
Don't charger when monitor standby battery drain, please use currentwidget monitor and use its log function to record. What is "the standby power consumption" pls consult Mr. Google.
Other users reported that changing the sd to another one solved the high drain in standby for them, so you basically are saying the same.
I use the original 2GB card the few times I decide to test android, because first time I tested superram build, my 16GB card got wiped for some unknown reason; I may as well see if your method changes anything.
Worked for me! Tnx!
Had 50+mA wen using android sd, very annoying because in the beginning I had no problems.
Now it's back on 8mA! Tnx!
Thanks
Thanks for the solution, seems to work every now and then when i get high drain on standby ^^ thanks
At first try, this seems to work well. I was getting 60+ ma usage in standby with Darkstone's SuperRAM build, even with a fresh install. Going through this little bit of voodoo got my standby usage down to the 5-8ma range. Thanks for finding this, though I don't like thinking about how much trial and error it took to discover.
I just hope I don't have to do this every time I reboot.
Thanks...
Was getting low power usage through this morning, when I unplugged the phone from the charger. I had left Android running on the phone overnight. I discovered that the HD2 was back to using 60ma when I got back to work. Repeated the magic spell, and I was back down to 8ma in standby. Really strange. Does anyone have any kind of explanation for this behavior?
Wow thx work like a charm.
imrazor - My theory is by pulling the SD card out in WM you stop all applications that use the SD and when you boot android the SD card is only used by android. Well thats what I think ^^
The point is it works and we now have better MA in standby.
Sort of works
The SD fix does take the standby drain to around 7mA, however I can only wake the phone once. The next time I try to power up, my phone never cuts on, and I have to pull the battery.
This is exactly what I am looking for. I will try it. Is it possible to write a program in WM to do this instead of pulling out SD Card?

That's an amazing solution.
If someone can tell me what to kill, I can try do create this nice prog...
Any idea why it works?
Didn work for me... Dont know did I do it right? I normaly shutdown my phone, do those things with the sd card (plug in plug out) and when I start android continuesly 50-70mA on stanby.. I did the battery thing and still the same...
Have MIUI SD ROM.
Current changed from time to time from 5-8mA to 50-70mA and back.
Killing all applications sometime give effect to decrease current.
Switching off autolight sensor sometime give effect to decrease current.
Sometime call in/call out give increase current.
Switching off in-pocket and near-ear sensors (call settings) give good effect to decrease current.
...
continue testiing
my head is overheat
switching on near-ear sensor after call return power consumption to 60-70mA.
switching off near-ear sensor not give decrease current.
call in/out not give effect.
sw on/off auto backlight not give effect.
sometime callout decrease current to 6-8mA,
but best result give system restart
Turn off HTC Sense

HD2 SD android standby battery drain 50+ma comes from 3 places:
1) What was running in Windows Mobile when you boot Android
2) The Android ROM you use
3) What is running in Android
1) The answer is turn off HTC Sense
When I turn off HTC Sense in Windows Mobile I get much better battery drain in Android. If I do not turn off HTC Sense then I usually get standby battery drain 50+ma. So flap can you create a nice prog to turn off HTC Sense etc. and then boot Android?
HTC Sense is not the only program. In addition to turning off Sense first, running a RAM cleaner (e.g. cleanRAM) in Windows Mobile will also help or - even better - reboot Windows Mobile without HTC Sense before launching Android.
2) use Portadroid to easily try different SD Android ROMs
3) see BetterBatteryStats

I started having this problem one day randomly (after i installed some new apps). However, even after i installed all the new updates and apps the problem persisted. I tried this method you mentioned and now my battery standby drainage is back to 7mA (instead of 30-60mA). Don't know how it works, but it solved my problem. I have since reinstalled the apps that I wanted and it has been working fine for 24hours...
thanks man
hi i just ask you what mean Tf Crad? SD card or SIM card
Hello, it doesn't work for my HTC Leo. I have battery drain 230-800 ma on the latest MIUI SD ROM. Any idea what should I do next? Maybe I must change the program, that measure the battery current? Now I'm using CurrentWidget.
Thank you, I will test it.
hi i am currently running the latest version of android on my sd card-(americanandroid 4-2-11)...i noticed i only get about 3-4 hours of battery life on my phone with wifi, bluetooth off and screen timeout after 30 seconds..i have no active widgets on homescreen and the battery is brand new...what do you think is the problem???
ps.-- i am running a stock tmobile rom with radio 2.08...
SD Builds have bad battery usage, that's a fact. You can always try to flash a newer radio onto your device to improve battery usage, but I don't know if this is possible without problems because of your sim-locked phone. Solution to your simlock:

I also think the battery of your phone is getting "lazy". So you might want to switch to NAND roms (go for gingerbread as it has the best battery life) and maybe get a new battery for your phone.

I ran the AmericanAndroid[3/20/11] and had over 26 hours of battery life among which 18 was of heavy use. I had brightness on minimum(NO AUTO), Screen Time-out was 1 minute, WIFI always on since I don't use my HD2 with a data plan, Auto-Sync, 2G active on mobile network instead of 3G/H.
The reason how I achieved this was because of proper battery calibration. There are a few factors that affect it. The most important ones being the percentage your battery level was at when you first booted into Android how you charge your phone.
Here is what I did to "calibrate" :
1.Charged my phone to 100% for 6 hours straights while it was turned ON.
2. Power off the phone while it is still plugged in and left it to charge for another 15 minutes.
3. Unplugged, removed battery, pressed and held the power button on phone for 5 seconds.
4. Turned the phone back on and once I saw the Boot screen(Android), I plugged it in.
5. Deleted the battery stats file using the following in Terminal Emulator :
Code:
su
(Hit enter)
rm data/system/batterystats.bin
(Hit enter)
Once that's done, use your phone as much as you can. to drain the battery. Let your phone die by itself. Once it dies, keep turning it on until it doesn't turn on anymore. then plug it in and boot into Android as fast as you can. If you repeat this one more time, you should see significant improvement in your battery life.
This "tutorial" isn't mine. I read some of around here itself and found some of it on other forums dealing with battery care. All credit goes to those OPs of those TUTs
same problem here
i would appreciate if someone could explain to me why my battery drops off like this and my signal is so intermitent

Booted into windows for a while?
I Have a HD2 on MIUI rom and whenever i lock the phone it turns off the phone.
Any ideas??
try another rom i think its a bug in your rom.
Hi
Ive tried many roms and im stuck
On my normal battery that came with my phone it seems to turn the phone off when its locked, however i brought a chinese extended battery (thinking it was the battery that was at fault) and with the extended battery when the power gets to about 60/70 it starts turning it off when its locked, but when the power is at above that its all fine but sometimes i get SoD
hmm.. try to put original battery in your device and reflash your rom.
otherwise i´ve senn that there are some roms which support your extended battery.
i think you can get the fix in the nand dev section.
sorry but i only have the original battery so i can´t help you anymore.
hope you get fixed it.
Ive tried flasing roms with my normal battery and it still doesnt work all i really want is for my normal battery to work with my phone properly and dont really mind fixing the sod on my extended battery.
Do you think my battery could be faulty? Also the bottom half of my phone heats up A LOT!
