[Q] battery drains - HD2 Windows Mobile 6.5 Q&A, Help & Troubleshooting

Hy guys,
for the last week or so I've noticed my battery drains a little faster, now to be honest - I'm kind of a pedantic freak when it comes to my hd2 (like everything else in my life..)
anyway.. off course i went trough every little change\installation that was made prior to this issue, those were the only changes:
*installed NFS shift - deleted it after playing it once since it drained 10% of my battery while playing for 3 minutes, so i still have a feeling that it had something to do with the battery issue.
*installed sims3 3d
*installed spore creatures
i cant think of any other changes made that may have caused the battery to drain a little faster.
i have a feeling that NFS was the one who caused the issue because the battery started draining faster right after i installed it and deleted it, could it have made changes to the proccesor's\mem\registry's internal settings perhaps?
the changes i'm feeling is that the battery will drain 10%-20% faster than before, if i had it on 90% from 8am to 1pm, now it will be on 80%\75%.
appreciate your help guys

anyone?....................

Batttery tends to drain quickly if you have Bluetooth on all the time,
Hope this helps

Battery Woes, extremely hot device!

Hi guys, I finally sorted my issues with the disappearing radio, but now it seems I have another issue.
Starting 2 days ago my battery just started draining like crazy, I'm lucky to get an hour or 2 of use out of the thing.
I noticed when I plug it in to charge it it takes forever and the device gets extremely hot. The battery is so hot you can almost burn yourself when you touch it. Maybe its just my imagination, but it seems to swell slightly when it gets very hot as well.
Obviously I have stopped using my device as I am worried about the battery catching fire after all the Lion battery issues lately.
Just wondering if anyone else had experienced this? Is the battery covered by any type of warranty?
I'm sure I need a new battery and I'm hoping that will fix the issue, hopefully its not some internal problem that is causing it to overheat.
Thanks in advance,
-Kai
Have you backed up your device and hard reset to rule out any software issues? I've run into this before, and there was something running on my device that cause the battery to drain VERY quickly. Never figured out what it was, but after a hard reset and reinstall, everything was fine.
I've had similar issues since putting black 3.01 on, draining anyway, not overheating as yet. I have stopped the battery draining by instaling Daniel Herrero's Bandswitch and setting it to gsm during the day, it seems to switch between gprs and hsdpa more frequently now with 3.01 which drains the battery enormously. Havent done a hard reset yet though.
you should feel my battery after tethering for hours, sigh....
Hmmm, mine spends half the day tethered at work, no heat issues thus far (apart from one time I left it under my pillow (too much Jack) and the heat woke me up (Not a great way to ease into a hangover)). I only ever have battery drain issues.
Yeah I dont think its a software issue as I have done several hard resets, and tried it with a couple of different Rom's and radio's, with no other software installed.
As for the 3g draining the battery, I have my phone set to only use Quadband, not UMTS or 3G.
I'm hoping to pick up a new battery tomorrow and maybe that will solve my problem.
I wonder if I might be able to get a new battery for free from HTC? I'm going to send them an email and see what they say.

same problem here
Hey invictive,
i have the same problem, and am also thinking about buying a new battery. plz let me know how the new battery work.
thx
I've just had the same problem. It was red hot in my belt clip & bat low warning.
Mines only 3 months old, been fine until now.
There were a lot of apps running incldung camera & wifi.
I'm going to charge again & close all apps, see if its ok.
had the same problem with my first tytn. called htc support (germany) and they told me that this behavior is not normal (obvious)
i recieved a free replacement, allthough i had to send in my tytn and not only the battery.
edit:
it was even worse with wifi turned on...

[Q]Ksmd and dhd_wakelock?

I've been seeing "ksmd" in better battery stats as eating up a bunch of my battery, and also lots of dhd_wake locks. I've googled both, work very little to show for it. Any ideas? It's weird, running neutrino 2.2 for weeks work great battery life, then this started happening and almost tripled my idle battery drain
Sent from my Supercharged Atrix
I cannot see what it is, but it IS our main source of drainage of battery.
I have read it has to due something about page file and kernel optimization for fetching memory thought. Lets try a Clem kernel and report back
Here, here. Bump on this I'm trying to get my phone into deep sleep mode, not a lot on the net about this process.
On random days i still get massive drain that I'm pretty sure is due to this 'dhd' process. its keeping my phone awake pretty much at all times.
yesterday i had great batt. life, and today, well, its like night and day...

[Q] Vibrant - Gummy - Battery Life

Hi,
I installed Gummy 1.2.0 on my vibrant. The first day or two I was getting amazing battery life. For instance with light-medium use, 30% of the battery was gone in 12+ hours, I was amazed. When I was getting this type of battery life Android system was using about 6-7%.
I noticed that as time passed, the battery life started getting worse and worse. I noticed that the Android System was eating up more and more battery even when it was supposed to be in deep sleep. Now Android System is using almost 40%
Has anyone else had the same experience? Great battery life changing to mediocre battery life in a couple of days.
Please advise.
Thanks!!!
I suggest you get Betterbatterystats and that way you can see exactly what is causing the problem. It is available in the market, but there is a free version here in post 2. IIRC the AOS taking so much of your battery life is bc of some errant process that is constantly drawing/polling on the system and causing the dismally high % of use. Find the app, fix it and your problem will be solved.

[Q] HTC One X+ Overheating and Affecting Battery

Hi All
I have had my HTC One X+ for roughly 3 weeks now and just recently I noticed the phone reaching a very hot temperature, I have not measured exactly but it is significantly hotter than I have ever noticed since owning the handset. I don't use it that heavily i.e. for games etc and only charge it when the battery is less than 20%, I have not needed to have the power saving setting turned on because the battery life suited me without the settings. However when I noticed the overheating it seems the battery is draining much quicker, A full charge went down to 8% within roughly 4 - 5 hours without any heavy use.
Can anyone assist me on this
Thanks

The damn things using more power than what the charger gives out.

Did you update?, i just played a game with the charger plugged in with full battery, after 10 mins of game play my battery was at 95% and that with the charger plugged in, my battery life wasnt as good as yours before the update but it was def alot better than it is now, theres quite a few more bugs since 1.16.401 and up, touch screen is dodgy as hell, that could be one reason for the battery drain, im seriouslt thinking of selling it and getting out my onex.
No I havent done any software updates, currently have the latest version available which 1.14.161.18. The problem only started yesterday out of nowhere, I can't understand what is causing it!! My usage has not changed at all :S
I was having the same issues the second I turned my HOX+ on. I have fixed it by not using LTE all the time. I found that when LTE was on, it over-heated my phone and killed my battery life especially when restoring my gmail on initial setup with settings and apps coming down from the cloud.

Vbus_wake_lock wakelock keeping the phone awake

Hello everyone,
I've been following these forums every now and then and was very helpful when I encounter some minor problems so far.
But lately I start having a very strange problem on my mom's phone which is a Samsung Galaxy Win (i8552- stock rom- android 4.1.2) and couldn't really find a decent solution or a good explanation so far. So I decided to ask you guys.
The problem is phone is having a bit poor bettery life overall, especially while in idle. I found out most of the times it is losing 2-3% battery per hour while idling (i.e overnight). Sometimes it's slightly more 1% per hour and sometimes between 0.5-1% (which sounds more normal).
While in idle usually Androis OS seems eating up the battery around 50-60%. I disabled most of the notifications, most of the sync options (especially google ones), all kinds of screen sounds, facebook update intervals, uninstalled Avast and also disabled the location access. But these changes didn't really give a noticable difference. Battery drain inconsistency was still there.
After I noticed this strange battery drain I decided to digging it up a bit more and installed GSM Battery and wakelock detector.
Firs that I noticed in GSM battery is that the phone is awake for like 1.5 hours out of 7-8 hours of overnight idling. And Android OS kernel seemed responsible for this. But couldn't really get more clues.
Then I found more clues on the culprit in Wakelock Detector under "kernel wakelocks" tab. Which is vbus_wake_lock wakelock.
WD shows vbus_wake_lock is awake for almost an hour after the last charge, which was 7 hours ago.
After I found this I googled around a bit but couldn't really found a useful explanation except it might be caused by an apple charger. But I know that mom's using the original samsung charger.
I tried rebooting to see if it helps. It's been almost 4 hours now, phone lost around 2% battery which seems ok-ish but the vbus_wake_lock is still there with 25 minutes of awake.
So any idea. What should I do to hunt this wakelock down?
I don't really want to make her worried about her phone though, she seems happy with it, since she is playing some games and charging it every day so not really having a battery issues. But I know that there's something wrong here and I want to fix it.
So I desperately need your helps guys.
Thanks a lot.
Sorry for my English btw, as it's not my native.
Best,
