What is killing my battery life?

My 8125 is suddenly running out of batteries very fast. I suspect this is because of some activity running - if I turn the unit off, and leave it on my desk overnight, it is exhausted by morning (I, on the other hand, am exhausted by morning only if I am turned on. Sorry.)
I have checked for:
alarms and notifcations that are set to go off - there seem to be none
mail and other internet access items - there seem to be none
programs (like SPB Weather) updating themselves too frequently - there seem to be none
My energy settings are normal; sleep in one minute, backlight down, etc.
Is there anything I'm missing? Any suggestions?

wifi, bluetooth. make sure they are turned off.

That's exactly, WiFi and BT even when active in standby really drain the battery quickly.

thanks so much, but.... Wifi and Bluetooth are off - I never turn Wifi on, and I almost always keep Bluetooth off (though I wish there was a way to quickly - or even automatically - turn it on or off, ie, whenever I use it in phone mode, BT would turn on, and when I hang up, it turns off.)
any other thoughts?

Battery Gone Bad
Hey I think your battery is gone bad.
BT Off
Wifi Off
Backlight Down
Sounds to me battery is ready to go to the recycle bin lol
Also check your MSN Msnger Is not onn all the time.

maybe it is the battery. the unit is less than a month old, but I just bought a spare battery. I'll compare run-down times on both.
a related question: why would WiFi and Bluetooth consume battery power if the unit is asleep?
-thanks-

I started getting horrible life out of my battery as of last month, but then I upgraded the ROM on it and have been getting FANTASTIC battery life. Better than when I first got the device.

which Rom did you upgrade to?

Summter <sp?> 2.3 for Cingular

Did you solve your battery problme?

when i am out in the country, where i might rarely get a signal, my battery drains real fast, prob to do with the constant searching for a signal to connect to.

I came upon this thread after my 8125 began having problems with the battery life last week. I'm wondering what kind of battery life people are getting and which settings they have.
For instance, before last week, I was getting little battery drainage during a 9 hour shift at work. Then this week, I was getting close to 55% battery drainage over the same duration. Just a few moments ago, I checked my battery settings and I found out that for some reason, my phone wasn't shut off after 2 minutes of idle time as it was originally set at. Okay, I'll test my battery usage tomorrow at work, but I suspect that was the problem.
Then it got me wondering how long other people have for battery life. With Bluetooth on, wifi off, lowest brightness setting and my auto shut off set at 2 minutes, I was able to last an entire 9 hour shift on standby with only about 4 - 5% drop in battery life. Hopefully, that is what I'll have tomorrow when I test it again with the auto shut off setting in place. What are others getting for battery life (please specify your settings).

I've forgotten to charge my phone at night before, and have had no problems making it through the second day of usage, though I'll usually get a low battery warning.
I keep Bluetooth and data connection on constantly. Don't use Wi-Fi unless I need something really quickly. Backlight is at the lowest active setting. I would say I use it moderately throughout the day. I use it to take important notes and make reminders for myself, along with surfing the internet without worry.

hi
Please check out activesync which drains the max battery..
make sure that activesync is not running in backround. once after disconnecting your mini-usb cable connectivity from PC please check for the activesync status.. if running turn it off.

Fast Battery Drain over night

Hi guys,
I have a problem with my Jade. I've charged it last evening and I've barely used it. When I've went to bed it was 96% charged (ARIELbattery) and 10 minutes used.
This morning, when I've woke up, The battery was 33% and and the phone was 34 minutes usage time.
Something is wrong. Since there were no bluetooth, no wifi, no anything activated. And for sure, nobody played with the phone during the night.
This is not the first time when I see this behavior, but is the first time when the decrease is so big.
I suspect an app, but I do not know which of them. How can I see it?
Do you have other suggestions?
thanks!

There are some possible reasons:
Some SD-Cards seem to drain battery, so you can take it out for a test.
Some additional software is told to drain battery. Did you install something?
It is also helpful to switch to "flight-mode" over night. This normally reduces battery drain to nearly zero, if no additional consumers exist.

Hi,
Yes I've installed some software, like gAlarm, S2U2, icontact,ThumbCal, Skype, etc but last night none of them was started.
What can I do with the SD Card?! I need the SD-Card. Which card does not drain battery and which does?
I cannot turn off the phone over night.

I've read those before posting, but there was no answer to my problem. I have 67% drop of battery in 8 hours without touching the phone.

This is most likely that your device goes to screenoff or unattended power state instead of sleep. Your power settings might be corrupted. To change that go to your power settings advanced tab and change everything there (checkboxes and sliders), press ok and then change them back as they were, press ok. I'd suggest to keep the device turning off in one minute while on battery and none of the checkboxes for cord powered mode. There is a really freaky thing that even if you get your device to sleep with power button it will go back to screenoff mode after time specified by the turn off device slider while on battery IF you don't have that turn-off-while-on-battery checkbox checked there.

Thanks for the answer. But I do not really understand what you are saying here.
My power settings are: 30sec for Screen Light and 1 min for Device (on battery).
None of the check boxes is set for the case when the device is powered.

It could also be due to the battery defect. After some time the battery could lose its storage ability (because of the defect), despite the mAH stated.
As a comparison, my battery is nearly one year old. On full charge, overnight drawdown (on sleep mode) is about 2%-3% .

I have no own experiences with this programs but Skype for example needs permanent connection to internet when activated (be care of the background job!). This uses data connection and this drains battery. I can not quantify this in %. In addition Skype does not allow the system to switch to deep sleep because it needs permanent connection!

None of the app was started. I just have Skype installed, but it was not used.

Uninstall S2U2 !!!!!

I found some German threads that discuss a problem with this software and battery life. Some loose 10% over night others 50%. I think you should try to uninstall (and afterwards soft-reset!) for a night and see what happens.
Please keep us informed.

First of all, I've disabled the 3G. Now it only gsm with gprs. Since I've done this it seems the battery drop is ... super ok. If yesterday morning I've had 33%, this morning I've had 20%, so 13% drop in 24h, and the phone was used normally as before.
last night the S2U2 was not started.
I will wait until the battery level reaches 10% an I will do a full charge.
I will keep you informed. Thanks to all for advices!

Some clues here too ...
http://forum.xda-developers.com/showthread.php?t=471365&highlight=battery+3g&page=2

Hi,
So now, 2 weeks later... after setting my Jade to GSM only (no 3G) I get 7-8 days of normal usage. As I said, before I always had to charge it the third day.
Normally, i get -28mAh drain in standby. When the screen is on around -130mAh (for wake up) and then -70mAh. In a gsm call i get around -250mAh.
I did not switch the phone back to 3G yet, but I will and I will see again the battery drain.
PS: the values were provided by Mobadi.

i believe i have S2U2 installed... and my phones fine!
i have the overloaded rom... and battery life seems great only needs charging every 3 or so days and i do use it quite alot!

so...
after some time of testing and re-testing I still have, from time to time, the behavior that during night I see a massive drop in battery level and an increase of the usage time.
I do not know what is going on, but I suspect that some app is waking up the device to do some work (without turning on the screen), and the Jade cannot go to sleep anymore for a while.
I've notice the same behavior on a HTC Diamond 2.
Since none of the app I have installed on my Jade are installed on my friends Diamond2, I have no idea what app could do that.
If anybody has any idea, feel free .... I am idea-less!

I've made myself a little application to log the current values of the power data. So, I've saw that my phone wakes up each hour by himself, without turning on the screen, does some work (cca -70mA) and after 30sec goes back to sleep.
Any ideea about this?

Wlan when standby and battery when not using

Does enabling wifi when on standby drains battery, even if you're not connected?
I made some registry changes yesterday and I also enabled this with wifi, and I woke up with 20% less battery, normal for me is 7-10%.
I can't figure it out what I did wrong except if wifi is the problem?

yes if your wifi is on it will consume more battery. check if your mobile is constantly checking for new mails or updating the weather. disable them if you want your battery to last longer.

I would like to disagree completely. I've already ran rigorous test just to prove if it does or not on MY HD2. And let me tell you that it does not. YMMV.
It eats just as much battery as if you're using it but without the display on. So in any case, it eats less because the backlight remains off.
Using DsE V6.5 ROM. I got my battery to drain 3% every 12-15 minutes leaving Weather to update every 30 minutes and Send/Recieve new Mail every 5 minutes, Have pandora playing in the background and leaving web browsers opened, google maps activate.
During my test, I recorded the time and the % drop. I started at 9AM @100% and Dropped to around 3:30PM to 7% battery left. Now remember, this is a constant run without turning the device off, never turning wifi off and without exiting any windows. Also, Ive set my device to dim the screen after 1 minute and let it blackout after 2 minutes. Just take note that every time I picked up my phone to change a pandora station or read a new email, I never push the "end" key to let the screen go blank instantly. I let it do its full 2 minutes thing and let it go blank automatically.
This is just so I remain very rigorous!
This has helped me understand a lot about my battery and how much I can pull it out during a full days or usage.
I noticed that My battery can last up to 6.5 hours of basically, NON-STOP usage. Just image if I turned off wifi and only needed it the moment I wanted to check if i had new mail, etc. My battery would last ALL DAY.
FYI, under normal use, my battery is around 55-65% by the end of the day under moderate use.

I have updates every 6 hours for weather, but I can see it connects to 3g when is the time. This is not the problem.
The problem started yesterday/today when I made some registry changes...I enabled 24bpp colors and I turned vsinc off.
I am not connected to wlan, it is turned off, I only enabled the option "enable when in standby" if I sometimes need it when phone goes in stand by.
I am asking...does enabling ENABLE WIFI IN STAND BY eats battery when NOT USING WLAN AT ALL?
Thanks

Screen stays on after battery gets fully charged

Got a weird problem with my AT&T stock non-rooted S4. About 4 or 5 times since I got it on release day when I charge my phone and I get the notification that it's fully charged the screen won't turn back off. I use a Belkin Conserve socket that is set to shut off after 3 hours and I've woken up after charging to find the phone dead. I've managed to catch this happen once and when the fully charged notification comes on the screen won't go to sleep, it just stays on and flickers a little bit. For all but one of these instances I had blocking mode on so I'm not disturbed by email or text notifications in the middle of the night. It did happen one time when I didn't have blocking mode on. I use a pin lock for my lockscreen and usually have BeyondPod playing overnight (only one hour long podcast while it's still charging) if that makes a difference. Is the function that enables the screen to stay on when you're looking at it malfunctioning? Any help? I've attached two screenshots of battery life when this happens.

So in settings under the Developer Options, there is a setting "Stay awake" if checked screen will never sleep while charging. Now I see that your Belkin shuts off the power but your phones still detects the usb plugged into a power source.
I think things happen in this order: you hookup your phone to charge and shut off your screen, phone charges to 100% and screen lights up saying fully charged, it stays on because of that setting, Belkin kills the power, it is still hooked up to USB so ... you get the rest.
I would find that setting and disable it.
if your next question is "I don't see developers option" it is hidden by default in android 4.2.2 so to make it available, go to Settings > About phone and tap tap tap Build number seven times. Return to the previous screen to find Developer options. Or Indiana Jones might pop up and give you the cup to get eternal life !!!

Thanks for the reply Commodore64 but I already checked that setting when it happened the first time and it's not checked.

No one else has had this problem?

I have this problem as well as my wife's S4. around 3am, I notice our room is bright with our two phones' screens on. It will stay on until the morning.
In the developer's section of the settings, the stay on when plugged in is NOT checked.
Also, on our phones, we notice the phones overheating because the screen is on for hours at a time at night.
I've just spent an hour looking through the internet, and while many report this, they are simply being dismissed by others as in having "checked" the setting in developer section.
Also, when the batttery does get fully charged, the "Battery if full, unplug the power" notification also rings the default notification ringtone. I've installed phoneweaver to set my phone to no sound overnight, but it only stops the sound, the screen still stays on and phone gets really hot.
This is turning out to be a huge problem for us.

Do you use a PIN (number) lock? I did but switched to the pattern unlock and it hasn't happened since. Also, I've been trying to charge only during the day or evening, not overnight. Maybe, since I charge during the day and I use it periodically while it charges it doesn't go into a "deep sleep" like it would if it charges while sleeping and the full charge notification would keep it awake. I don't know exactly why but it hasn't happened since. Hope this helps.
