Hi korban,
What you can do is once you are out of an app and don't need it any more, go into your recent apps and remove them. Then go into your usage and "end" them if you can. If WiFi-needy applications are running in the background, they are most likely constantly eating up your battery by constantly syncing with the WiFi and internet. Also, DO NOT remove them from your recent apps if you still need that application and don't want it to reset. Such as, playing a flight simulator, and then pausing it. Then going back home. If you remove that from your recent apps, then the flight will start over again and most likely not saved. If you need any more help, I'm right here. Hope the problem is solved!
Also, try to wait until your battery is completely dead before charging it, or near dead, such as 1-10 percent, and then charge it undisturbed until 100 percent. This will increase your probability of your battery not getting damaged by the interrupted charges.

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.
Some clues here in this forum

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.

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 ...

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

battery drained out.....any idea

for some odd reason my battery was drained out very fast, i mean fast....
i thought it was my battery but i guess its my phone....cuz i bought a new battery n it was at 60% n less than 3 min it was down to 6%....
is there a way to fix this or is my phone broken...
any help would be good....
thank you!!!
Enter *#*#4636#*#* in the dialpad, that brings you to a service menu. There, go to Battery History and select Partial wake usage. That shows you if you have some app installed that prevents the phone from sleeping.
Also, the battery needs to go through a couple of full charge-discharge cycles before it reaches it full capacity.
Hope that helps!
Was it hot?
Hi,
To dissipate that amount of energy in that time would make the unit very hot indeed.
Is the unit getting hot?
If not, then the energy wasn’t really there and it’s likely your battery is damaged/faulty and needs replacement.
Regards,
Paul.
The best advice i can give you is to find a widget that disables your data connection.
I used to have major battery drain. ie: Right after a charge, i only got 97%. By 10am, with almost no usage, im on around 68%.
Now, with data disabled (when not in use), i am still on 95% since i took it off charge at about 12am in the morning!

Can I ask you what widget you use for that? I'm facing the same problem: 94% right after recharge and rapid discharge after that.
Try "Data on demand", worked for me.
P.
data on demand is brilliant.. but I don't think that is the problem that the OP has experienced - no amount of data use would cause the battery to drain that quickly.. it's likely to be 1 of 2 things..
1. Faulty battery.
2. faulty app which is battering the processor and using 3g/wifi at the same time..
no the battery is not hot....my phone was working fine this 3 day ago....n now with the new battery is still the same.......
i also turn of everything on my phone n restart everything...with 0% this morning ....with my phone n now im back home im still at 23%.......is it virus?...but i scan my phone with this app from the market n its fine........
Timescape and Mediascape might be the cause
Hi, I had the same problem. I had to charge my phone three or four times a day. I read in a thread here that some people removed Timescape and got amazing improvements. I removed Timescape, Mediascape and other applications I don't need. Your phone must be rooted for removing these applications.
This night my battery dropped 3% in six hours. I now charge once a day and is happy with that.
Helps to mention to them any side effects of removing timescape n so forth..
Sent from my rooted 026 X10i using swype via XDA!!
Yeah, removing timescape and mediascape is a good idea, i also removed the phone dialer, and the browser because it was draining lots of battery, and also removed parts of the Android UI but figured it was still using some battery, so i now use the shell on minimum screen luminosity and always on plane mode !
Yes, you can mock about it, but both Timescape and Mediascape got replacment apps which are actually way more usable and gives me more than just a fancy user interface.
That is one of the good things about Android. I am not locked to any application.
Sorry to take over here but whats a good replacement for timescape? I've tried many phonebook apps and they all look horrible.
I would really like the HTC sense phoonebook any way i can get that?

I don't know about that but theres apps such as acontacts, takephone (something like that) n quickcall!
Sent from my rooted 026 X10i using swype via XDA!!
It happens to me once, from 92% to 36% in just under 6 minutes. Then draining very fast after that. I removed one application I installed (can't remember the exact name) and rebooted and it never happen again...
phone is dead now..........
wont charge!!!!
this suckx!!!!
wast of money!!!!!!
You need to take it back buddy - it's obviously faulty.
Dear all members,
I plug in the phone yesterday for charging and probably due to the charger was not plugged into the socket probably, it is not charging.
To my surprise, when I wake up in the morning, the battery was drained and shut off.
I try to charge the battery up but the charging seems a little slow now, is the battery faulty?
I can feel the back of the phone was hot though.
Definitely something wrong with my battery, I have been charging from morning till now and the battery never charges up to 22%, when it reaches 22%, it will drain out slowly even the socket is still connected.
I will have to bring my phone down for them to check.

[Q] Strange Battery/Phone Issue...anyone have similar experience?

This is strange. I know everyone is probably sick of these battery discussion threads but something weird has been happening.
I have ATK and UltimateJuice and with the two I can go 8 hours at night and lose MAYBE 1% battery. If I then use the phone normally it will last about 2-3 days with around 1% loss per hour (more or less, depending). Well, I find after opening numerous apps the phone begins to lose more battery per hour, sometimes upwards of 3-5%. I check ATK and nothing has changed that I can see. After restarting the phone the charge lasts longer and depletes at a much slower rate. So, this begs me to ask:
What is causing this and why?
and, How can I stop it?
All insight is appreciated! Thanks.
Notes: - same location for both cases
- WiFi enabled in both cases
- GTalk and syncing the same
Anyone at all?
i have an average of 8-9% battery loss overnight with only Google account on an active sync. over the day it'll drain randomly too. sadly.
no idea why but i'm living with it.
People well tell you not to but get ATK. I ignore all apps for syncing and important stuff and have it kill stuff like gallery, etc. I found it helped a lot with saving battery. UltimateJuice helps a lot with battery as well. I'm at 70% and it has been over a day an a half now.
the think i learned about all those auto *whatever* programs, they always end up causing more problem than what they solve
i only use them to manually end task apps that i don't want to have in memory anymore
otherwise i just leave them running
no effects on battery life
the battery life is more related to the WiFi usage & GPS usage
if you are not using any of those 2 just manually slide down the tab and click them off
you can go a whole 24+ hr if you keep GPS and WiFi off, and only use 3G/voice in moderation

[Battery Stats] I didn't bring my phone to work today

I had everything turned off. No email, no sync, no wifi, no gps, nothing. I fully charged the battery and unplugged it before I left. Display was never turned on. I wanted to see a completely isolated battery test. The only applications I had active according to my task manager was Launcher Pro.
Time on 10 hours 20 minutes
Battery life left 60%
Battery used 40%
Cell Standby - 40%
Phone Idle - 30%
Android System 20%
Calls (1 missed call) 5%
Display 3%
Maps 2% (Why does maps show up?)
Again this is with absolutely 0 use or syncing going on. Left phone at home, turned on and immediately checked stats when I got back from work.
According to this small test I can't even last a day on a full charge even if I left it completely alone.
Thoughts?
Running stock JI6

In 1.5 day of standby with every radio off and no sim, my phone only lost about 5% with stock JI6.
I think it is a cool idea. I find that 5% usage for one missed call is very bad. I have really suspected that voice calls kill this battery and that seems to add evidence. 5% for a missed call? That is messed up.
I think this is the aspect of battery life that doesn't get addressed enough: drain during standby. Of course everyone expects to lose some power while the display is on and syncing/other processes are running--but what about when the phone is left untouched? Here are 3 ideas:
3g is a notorious battery drain even when the phone is not being used--use 2g instead.
Freeze or uninstall media hub and other running processes that attempt to run/connect to servers in the background. I removed dmservice, media hub, and all drm processes and this seemed to be helpful.
Use a custom rom--these appear to hold power in standby better than stock roms do.

Cell Standby indicates that there is an activity that polls something from the network.
if you are so concerned about what it might be, you can see when and how much data is being used by going to your TMO account online and check for the data usage - one of the good features TMO put in place is actually tell you when your phone connected to get what amount of data over the data connection, does not tell you what it was doing though.
Yeah, something is going very wrong in your phone. When my phone is on standby with just 2G on it drains less than 1% per hour. I would definitely recommend getting rid of the drm service and media hub (and Daily Briefing). I also use Autostarts to keep all kinds of random programs from starting at inappropriate times (Really Slacker, does your app need to launch every time the time zone changes?)

According to Samsung the phone should last 450 hours in standby mode...

I wonder if Samsung's definition of "standby mode" is what the rest of us call "off".
I've never had any kind of batt life with this phone...charge everday overnight...start work at 8, use here and there for navi (around 10 mins max, maybe 2x a day) about 30 min avg talk...and mp3 player...get home by 4 and always at 30% or (most often ) less...have had stock/ bionix roms, never changed, no matter what build....it's pathetic..called tmo, they said there are no known issues with batt on this phone...wow...do a google search on it..anyways, they are sending out a new batt..I hope I just got a bad one...seems very random tho, some ppl have all radios on ,screen all the way up and get 10+ hrs...if i left my screen on (say navi on) for more then an hour straight I'd be out of battery..very weird..praying new batt is better...

Does it seem like youre just not getting the battery life you should from your phone? Do all your other friends keep going while you slowly putter into a shutdown? Well pout no more! Simply follow these steps to clear your batter information from the phone and your phone will act better then new! :)
1. Charge phone completely, leave plugged into power
2. Boot into recovery
3. Wipe battery stats
4. Reboot to normal
5. Remove power cable
6. Drain that sucker all the way
7. Recharge fully
8. Rejoice!"
I turned my phone off today. Then I left the house. When I got back the battery was glad to see me. Seriously, I've read just about everyone and almost started my own battery disturbance thread. I've come up with a new thought at least for me. I don't care any more. I have electricity. I have a spare battery and a charger. If my phone wants to last a whole day. Yay! If I use it more because of some game with angry birds or cards or dice, great. I've reached that Mark Twain moment somewhat tweaked when he said,
“Age is an issue of mind over matter. If you don't mind, it doesn't matter.”
I'll tweak it with the last 27% of battery left in my feeble vibrant to:
"battery is an issue of mind over matter. If you don't mind, it won't matter".
Enough already I say! Lets spare the air. Batteries are meant to be used
Back to the regular reading of all the battery threads now.
I think I had the same issue as you. Cell standby was the biggest drain. When you tap on that, do you see 50% time without signal? If that's the case, this seems to be a bug in Android which was somehow introduced in JI6. The best solution I've found so far is after every boot to put your phone in flight mode for a few seconds and back. This fixes the radio glitch, your time without signal should go down way under 50%, and battery drain should stop. Hope that helps.
You should recondition your battery:
Fully charge
Reboot into recovery wipe battery information
Reboot into OS
Unplug power cable
Let battery FULLY drain (do not plug in until fully dead)
FULLY charge battery (do not unplug until fully charged)
This reconditioning should be done after every ROM flash.
