Excessive battery drain

My Alpine has suddenly decided to drain its battery very quickly, for no obvious reason. It just went from 100% to totally flat overnight, and this is with GPRS, wi-fi and Bluetooth all switched off. Usually I can keep it at home in this state for several days with only a small drop in battery power.
I doubt the battery is at the end of its life - it's only a few months old, and it suddenly developed this problem, having been fine up until now.
Any suggestions anyone please?

hmmm....no idea about that...anyway you can check at http://www.batteryupgrade.com/ for more powerfull battery if you like it...

Has it only done it the once so far? Mine did it a couple of weeks ago for no reason, charged it back up and it has been fine ever since. Might just be a one off!

Mine has done this twice in the last 2 weeks
Happened since installing the Modded 162 / 1.04 rom from here?
Are others having the porblem using this ROM? if so may be worth a ROM change

I've now done a hard reset and this seems to have solved it. I'll let you know if it happens again. I doubt it's the ROM version, as I have the latest official O2 released ROM.

I've found the culprit!
... well, I have half an explanation anyway. Last week, I updated my ROM from the official O2 site - to Ext ROM 1.11.169. I have now hard reset and reverted back to 1.11.162 (with Radio 1.04), reinstalled my software, and it's all working as normal.
I run Tom Tom Navigator 5 - don't know whether this had anything to do with it, but the power drain characteristics were similar to if I'd left Tom Tom running (except I know it was definitely closed down). I even hard reset and uninstalled Tom Tom and the problem was still there - until I did the ROM downgrade to .162 again.
Anyway - it's fixed - I hope this is useful if someone else gets this problem.

Overheating and abnormal battery consumption!

Hello, I am new to this forum but it seems like the right place to post this.
I did some searching on this forum and I saw that I was not the only one with this problem, however I did not find any answers to the posts regarding this. I am hoping some suggestions will show up in this thread though
My Diamond has been acting very strange for about a week now. All of a sudden, my batterytime decreased from a (for me) normal time of about two days, to about 30 minutes. Also the bottom part of the phone gets really hot.
What's even more strange is that two days ago it somehow just went back to being fine?! Today it's back to it's weird hot/battery devouring state.
ROM-version: 1.37.413.3 SVE (Yes, I know I should update it...)
Radioversion: 1.00.25.03
PowerGuard says:
Battery Current: -324 mA
Battery Voltage: 3542 mV
Battery Temp: 38,9 C
I also have a few applications installed, like the answerkeys disabler app and G-alarm. But other than that it's pretty much stock.
Has anyone heard about this before? I don't really like the idea of sending it in for repair since it's about 10 days without my precious phone =)
Any suggestions greatly appreciated!

i have read on here before that it sometimes is fixed (or reduced) by updating the Radio.
i believe the BS14 radio is the best one for reducing heat and improving battery life.

I have had a similar experience....a day or better battery life has been norm for a month, until the other day when I noticed my phone was very warm/hot and had burned an abmormally high perentage of the battery life in two hours. I also had one occurrence where instead of the normal 7-8% overnight burn, it had used 70% of the battery life. I'm still trying to see if I can catch the culprit; some sort of latch up of the hardware or a program not behaving.
Let us know if your problem does go away with a different radio. I have a stock US GSM and am happy with the radio performance...(unless it's eating my battery when I'm not looking.

Ah, so I'm not alone then!
I have not yet had the time to try this as I have been working too much, but I will try updating the radioversion before I buy a new battery or something, that's for sure...
I'll post in this thread with results when I'm done!
By the way, if I upgrade my ROM, will that also update the radioversion?

battery/charging problem.

i'm using donut's android build and this battery/charging problem is driving me nuts. my battery lasts 4-5 hours max and the weird thing is it only takes 10 -15 mins to show my battery is fully charged. i tried flashing again, left the phone until it dies by itself and charge it, left it being charged over night but none of them helps. anyone having same issue? i know with android on our vogue the battery life sux but is it this bad??

might be time for a new battery. It should take 30 to 45 mins to charge. And it should last longer than that. How much time do you spend playing games ect. Gps also is a battery drainer. Also alot of data usage.

My battery can last all or most of the day with moderate use on Android.
If you are running off an SD card, try booting back into windows for a day or so to see if you have a similar battery problem there too. Actually, windows battery life was MUCH worse for me. The difference is that Android does not wake the screen for Calendar alerts or text messages like WinMo does... though in Android you do still get the vibrate or sound alert.

win mo is actually quite ROM dependent (NFSFAN's ROMs got awesome battery life). android is pretty kernel dependent. if you are charging overnight, and using latest zimage/kernel, and turing off syncing (background data), and that is the battery life you are getting, you need a new battery.

i use gps a lot as i work as a field technician but i don't have gps turned on all the time while im driving as the screen shuts off by itself in a minute or so. maybe gps is still working even with the screen shut off? and it's a nand install so trying with winmo is not possible. i had much better battery life with winmo for sure. if i turn off the syncing will i still be able to use gps?

Which NBH are you using? The newest ones are way better than the older ones. If your using a current one check out tatnai's FAQ... http://forum.xda-developers.com/showpost.php?p=5599516&postcount=33

It's the kernel. you know the file you rename RUU_signed and you flash.

I am definitely having this problem as well, and the charge does not last very long it seems either. Was much, MUCH better in the Windows Mobile builds I was using previously.
I am on Bell using the basic HTC Touch

Same problem here. Brand new battery on bell.

Yeah, although battery life is positively improved and pretty decent now, there is definitely still something funky going on with charging. I still don't rely on / believe when the phone says it is fully charged. It happens too quickly to be possibly true.

I have the exact same issue and it is absolutely a problem with charging within Android. I have two identical batteries. One was fully charged in winmo before I flashed - I took it out and swapped for the other one. Flashed it with that battery in and charged it overnight. It only lasted about a half-day. Came home and swapped out for my other fully-charged (in winmo) battery, and it lasted for more than a day. Same settings, same use. After it discharged, I recharged overnight from Android and it behaved the same as the first - discharging in about a half-day.
What gives?
I'm curious what builds people are using? I'm totally new to this but I'm using warm donut with voguimg-240x320-06-04-10.nbh. It seems that nbh isn't posted on the sourceforge site yet - maybe I should switch back to an older one?

Maybe kernel problem.
I'm experiencing the same problem as everyone.
Lately my battery suddenly drops from 100% to 4%.
When I put to charge, it reaches 100% very fast. Should reach only 5%
I think it can be a problem in the kernel.
Now, i'm trying to solve it. If I find something I'll share with you
I can not determine which kernel brought the problem...
23/04 - 16:16 (GMT-3 - Rio de Janeiro) - Trying an old kernel
23/04 - 17:00 - Nothing. But came to the conclusion that the problem is with the battery.
Battery really "thinks" its 100% charged, since it accepts flash a nbh without the need of the phone is charging. And this only happens when the battery is at least 50% charged...

[Q] Suddenly Nexus battery drains quickly

Hello all.
I bought a Nexus One in at the beginning of the year. It's not rooted and I've had no problems from it till this month. I can not say the timing is exactly this, but it seems the battery issues started just after the FRG83D upgrade. I am accustomed to using my phone for most of the day before it needs to be charged. 12 hours or more with moderate use. Since around the FRG83D update my battery is about dead in around 4 or 5 hours. I haven't changed any settings or gotten any new apps or anything for quite some time.
For example, Friday night I charged my phone to 100% and then unplugged it (to plug in my girlfriends phone) and went to bed (about midnight). At 5:15am my alarm went off, i glanced at my phone and found the batter was at 10%!! the phone had been sitting there doing nothing all night with the screen off. I checked the battery use screen and it showed cell standby and AKMD taking up all the battery (55% and 35% respectively). I should mention that I have full signal where I am and have never had an issue. I cut off the screen rotate in the settings just in case that was part of it (AKMD being the gsensor i believe).
At next full charge that day i noticed the same problem, after being at 100% my battery was down to 10% after about 5 hours, almost the entire time I didn't use the phone. This time "display" was the largest percent by far (followed by cell standby), but clicking it showed only 15 minutes of use time for the display as I had purposefully not messed with the phone much.
Last night I had to be out and a bout so I decided to test things again. Charged full and cut airplane mode on. about 4 hours later my phone was down to 20ish percent, the only use of the phone being me looking at the charge level a couple times through the night.
I installed "spare parts" app and it shows my battery as being in good health and such but who knows how reliable that is.
Anyone else having similar issues? Any suggested remediation measures? I'm considering flashing the phone and reinstalling apps and such but would rather avoid that having never done that before and not having a desire to deal with setting everything back the way I have it.
Don't know if it matters but I run LauncherPRO and I do use the friends widget but it's never seemed to really cause battery issues before. I also run the news/weather widget, but again, no previous problems.
Any help would be great
Thanks!

In the spare parts app check partial wake usage. See if any apps are not letting your phone sleep.

nothing stands out other than UID 10073 which is handcent. currently my phone is charging but I'll pop it off the charger soon and watch the battery drop time again. I should note that inbetween all the tests so far i've rebooted the device so hanging apps of any kind should be killed off...

What ROM are you using?

Are you using Extended Controls? There is an issue with that and FRG83D. Uninstall it until the dev sorts it out.

yeah i am using extended controls. i'll take it off and see what happens.

Me too
I Have exactly the same issue, also have extended controls. Uninstalled and waiting to see if that works.
Cheers for the suggestion.

That did the trick! Loss like extended controls was the problem. A shame as i really like that app. Will hope they update and fix soon. Thanks!

Extended controls updated!

Yup, uninstalling fixed it for me too. Haven't seen the update though. I remember seeing an update yesterday, but I had this issue with that update so that did not fix it for me. Hope they update it again soon

I think it was updated again today. Now v5.03, and it seems to work properly.

So nobody saw Extended Controls showing up in Spare Parts, System Panel or other such programs?

Stock 20L: 3G disconnects then HUGE battery drain

Hello all,
I have confirmed the following issue on my Optimus 2x with stock 20L. Nothing else, nothing special.
When I leave the phone standby for several hours (eg. during the night), when I get back to it and turn on the screen, the network signal/3G indicators are white - meaning no internet connection.
After around 10 seconds, 3G reconnects itself.
While this is annoying, since you don't get any notifications from programs using the internet (WhatsApp, Facebook etc), it gets worse.
After 3G reconnects itself, the battery drains really fast: about 30 seconds for 1%. So in a few minutes your battery will be completely drained.
This even continues while rebooting.
For example: I come back to my phone and it has 46% left. Then I notice the 3G disconneced and reconnecting and then power starts dropping really fast. I reboot at 43% power left. After the reboot, there's only 18% left but the draining has stopped.
I at least had this happen twice in four days.
Is anyone else noticing this, or does any of the developers out here perhaps has a fix or a custom rom in which it is fixed?
I really like 20L for some new features, but I'm also experiencing issues with GPS and now also this... I'm really thinking of going back to 10D.
Thanks for any help or insights you can give me.

I also have huge battery drain, but in my case the main culprit is OnScreen Phone. Left my phone with 100% in the evening and in the morning, after exactly 8h, the battery was at 70%. Of that, 50% was used by OSP, and 25% each Idle and Cell standby. With the phone on wireless, froyo used at most 10% instead of the 30% used by GB now.

Yes you should remove all background running apps, especially the sh..y LG one Phone on Screen, but also checking for others, like media share programs and so on.
One time with my present ROM I had a storm in my battery with tremendous drain.. I had to do a fresh reinstall, and since then no problem.

Thanks for your replies, but this is different.
The battery only starts draining when 3G reconnects and you can literally see it happen.

Same happening here. I'm running on topogigi 2.0 SP3.
With Baseband 725 I'm having this issue. Now I'm on 622 will see tomorrow what happens
Edit: I'm noticing, that even if I have full signal with an "H" the phone starts switching from H to 3G and back when I turn the screen on

I think I can confirm that huge battery drain on GB is because of the radio. The reporting of huge consumption by OnScreen Phone or Gallery may be wrong.
I left last evening my phone fully charged on Flight Mode and after 8:30 it consumed a mere 1-2%. With Flight mode off GB uses like 30% and Froyo used 10%. So I suppose the radio is the main culprit. As you can see in my screenshots, the Gallery process is said to have used the most energy, but it wasn't even started. And some days ago OSP was in place of Gallery. In the third screenshot you can notice how the drain started when I turned off the Flight mode and browsed for 45 min or so.
Could it be that we're experiencing this huge radio drain because of the incorrect baseband? I suppose we all have the generic Euro Open/Italian v20L ROM, and maybe our networks need a correct baseband for our specific operator?

The first time i experienced the battery drain problem i had no rooted phone with official Gingerbread update from LG. That was last week. The Baseband was exactly the same as from Froyo 10D (725).
With Froyo I had no battery drain at all. So LG must have messed something up - that was my thought...
since then i rooted my phone and installed topogigis rom on fr, 4th nov. At the weekend i was in areas where the signal strength was very good (H in status bar).
On monday no battery drain on my place of work where signal is very bad (G in status bar).
Since tuesday battery drain is back. I get reconnects after reconnects when the signal is weak. Even when the signal is very good my phone jumps from H to 3G and back. What the hell is that?

You need to flash the GB baseband released with the rom, the 0725 basebands are not the same. Flash the 0725 baseband in the v20l thread of Hell_97 and try again. Without it there are many issues.
Sent from my LG-P990 using XDA App

Maybe I was a little uncertain:
- Last Wednesday (2nd nov) I had an unrooted phone with froyo. In the morning I checked for an update with LG Software and boom I had Gingerbread.
- Until friday I had heavy battery drain (9h and battery was at 5%). I was so angry and thought f*** you LG-Guys I'm flahing topogigi's rom. I flashed the Baseband 725 from his thread. On Saturday to Monday evening no problems at all.
- On Tuesday my phone again had very bad signal an it was often active (in the Battery-Usage Menu were much of those blue bars.
- Yesterday I flashed 625 Baseband -> problem not solved
- today I flashed 502 (from LG U660 10S update). I will look how it works.
What I noticed on all Gingerbread roms is, that the phone often Disconnects an Reconnects. I think that's making the heavy battery-darin.
But I have no idea how to fix that...

If you have updated through LG update tool, your Baseband had been updated to last (=the one recommended for Hell ROM), and above all the one recommended by LG for your area...
I think you should put back this one...

I've read many threads about this issue, but couldn't find a solution for Optimus 2X because on our phone, the PDP Settings in the HiddenMenu aren't implemented yet, so we can't disable Fast Dormancy.
I've found a workaround when you're at home: you can change the WiFi policy to never sleep, so during the night, the phone will use WiFi only instead of 3G while it's sleeping. But still, this doesn't hep you at all when you have no WiFi available.
I called LG this morning and they sad I'm the first reporting this problem (huge 3G battery drain on newly released Gingerbread)
Has anybody found another solution?
