Noticed something strange with battery level

Hi
I have noticed something strange happening with my phone. I have started charging it every night now so that it will be fully charged the next day.
When it is fully charged, I turn it off completely to save the battery, and to stop noisy email alerts. In the morning I turn the phone back on and it says 73% battery level, despite being turned off overnight, so nothing should be draining the battery.
If I leave the phone on Standby overnight the battery level is always 90%+ the next morning.
What the hell is going on? Does anyone else notice this quirk?

You can try another battery and oberve if the problem would still occur..

It could have something to do with the difference in temperature? In the morning it's coooled off and maybe that does something with the measurement?

Did you put ur fone into flight mode.

Huh, I've never heard of that before, but then I never turn mine off. When you say "turn it off" I am assuming it is when you hold down the off button for a few seconds and answer yes to "really" turn it off. I think its very strange that it uses more power off than in standby. Maybe you have come across a nasty hardware bug. Keep us posted.

Yes I do mean holding down until it tells you data may be lost are you sure.
And it is still doing it. If I fully charge my phone at night and then leave it on standby the next morning the battery gauge will say something like 96%.
If I turn it off, it is always under 80% the next morning, this makes no sense. I leave the phone in standby now with the volume off, and the backlight and power set to switch off.
I keep it in a cradle now, this is a stock photo, not my phone in the cradle.

Charge your battery to FULL, then take it out of the phone when going to sleep, when you WAKE up, put the battery in, if it's at 100% or 99% then it's your PHONE. If it's at 96% like you said before then it's your BATTERY.

Memory card draining power
This was a ROM bug on i-mate JAMin on the first ROM versions that was available. A memory card inserted will drain power from the device. What brand do you have and do you have a memory card inserted ?

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.

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!

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?

After charging full, dies out.

So it happened again. Fully charge the TF for a trip. When I get to my distination (8hrs later) turn on the TF and its dead. No power and no chargers. This thing is pissing me off!
Anyone know why or how I can fix? I do have the wifi off when screen is off.

How is that possible?
Did you not shut down your TF?

It looks like you are having the reboot during deep sleep issue that started with the upgrade to ICS. The reboots can be stuck with the screen enabled and the processor actively trying to complete the boot, which drains your battery.
Short term, I would avoid leaving the TF powered up unattended for long periods.
That will prevent the total battery drain. For a longer term work around, you can try an app called Wake Lock, which you can set to prevent the TF from going into deep sleep, and eliminate the deep sleep reboots, which has helped some users, including me.
The app should be set to restart on Reboot, and select the Partial Lock, then select the Acquire Lock setting, on the red bar, which will switch to green, and indicate that it has acquired. You can also set it to show its icon in the Notification are, so that you have a visual assurance that it is working. Then just exit the app, and it will work in the background.
You can monitor that it is preventing Deep Sleep, using the CPUspy app.
I would then watch carefully to see that you aren't experiencing any more reboots during Deep Sleep.
Long term, ASUS is researching instability with ICS, and we hope to get a true fix. Until then, use of Wake Lock may help you.
Others may have other opinions and explanations, and they may be right, but this has cured my problem for the last 11days. Good luck.

No shut down. I would charge the TF to 100%. turn the screen on to see if its 100% charged and that's it. Then 8hrs or so later when I want to go use the TF, its dead. Can't even turn on.
Can this be the reboot issue or an application that is running and not letting my TF go to deep sleep? Help!

Your response makes no sense. You say TF was shut down then you say TF might not be going into deep sleep. If you power the TF down it will go off and use NO battery. you will get some battery internal discharge but TF will not come on an use battery. Try the same test shutting it off.

Ok...try again. I would charge the TF. Then check by pressing the power button. The screen goes on and shows 100%. Then press the power button to turn the screen off ( not turning it completely off).
When I want to use the TF, it won't turn on, as if its completely dead.
Suggestion?

its either a) you get a RR and get stuck in a bootloop, b) you got some app running that drains the battery, such as Winamp or c) your device is broken (not likely).

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.

Turning on phone while charging

Hello all,
Recently i've been noticing that my GS4 battery is draining too fast, i think that it's time to recalibrate it. Since my phone is not rooted, i have searched for guides on how to recalibrate the battery.. and i found this one:
To calibrate your Android phone battery correctly:
1-First drain your battery down. Let the device switch itself off naturally. You will know if it is completely dead because it won’t switch on again.
2-Place the phone ion charge while it is turned off. Allow it to charge for at the very least 2 hours, if not 4, until the battery meter reads 100%
3-Switch on the phone while the charge is still connected to it. When your phone is on the home screen, leave the charger connected for a further 2 minutes before removing it.
4-Repeat the above steps twice more, always allowing the phone to completely discharge first.
The reason for leaving your charger connected is to allow the configuration files to update with the new, correct charge values. Some of the best ways to avoid battery usage is to make sure all connections are turned off when they are not in use – Wi-Fi, Bluetooth, GPS etc. Make sure your screen locks down in under a minute when not in use and that your screen is not set too bright
My question is.. is it safe to turn on the phone while it is charging? is it safe to turn on the phone when it is plugged to a charger while it is off?
Thank you in advance.

Hi
Yes and yes
BTW I do not believe to much in those battery calibration methods , as far as i know a new file is generated each time you switch off and back on

You can charge your phone in any status, on, off, flight mode, playing games etc.It will only affect your charging speed.
As for calibration - I have heard about such thing and try to discharge my battery till some 1-3% and full charge at least once a month. Don't know if this helps. I think also important is the environment temperature and how you discharge the last percent.My suggestion is that last percent must be discharged as slow as possible - with screen locked let it die natural way, with normal usage, very slowly. I and other usually switch all possible things to drain battery faster at this stage. That seems wrong on my personal opinion.

NO NO NO
Draining your battery is BAD!!! Draining it below 0 is the dumbest thing you can do. That damages your battery. Whoever made that "guide" has absolutely no understanding about his battery.
Calibrating is easy.
Charge to 100%. Pull your battery. Put battery back in. Charge again until full when powered off. Volia calibrated.
Though it will probably not help. My guess is that you just need a new battery (if it's no software problem).
