[Q] battery going from 100% to 78% after unplugged???

I have a problem someone might be able to shed some light on.
I am on call so i need to leave my phone on over night, i plug it in as i go to bed so over noight it charges. In the morning it is at 100% until i unplug it, it will go down to 78 - 85% of battery
Does anyone know why this happens??????
Thanks.

Did you calibrate your battery after flashing Criskelo's ROM? Also, the phone stops charging after it reaches 100%, so its if you think that keeping it connected to the charger all night long it will be charging all the time you're wrong. The phone stops charging to prevent the battery from overheating - charging resumes after some time though

I believe I did a battery Calibration, I used "Battery Calibration" to do this but this might not be the best thing to do a CAL.
I leave it plugged in cos i'm asleep when it gets to 100% otherwise i would unplug it, when i here it get to 100% i unplug it cos i only lose about 2% battery over night.
It should at least hold the charge at around 99 -98%.

I think Battery Calibration does the job - or you can go in recovery and wipe the battery stats there. Anyway next time that happens you should go to Settings>applications>battery use and you should check which of the processes is draining your battery the most

Nothing is draining the battery, I just want to know why after being on the charger "reading 100%" battery it drops to approx 78% after i unplug the Charger.
Even if i have everything turned on and running it should stay at 97% or above once i unplug the charger.

LOL that's just the battery acting if you don't have anything draining it. Also, just for information - you apparently haven't had everything turned on and running on the phone - I can tell you that the charger is not fast enough and cannot counter the entire drain of the battery, so you end up losing battery even though you're charging the phone and the worse part is that soon the battery overheats and stops charging. LOL

For crying out loud, use your brains and do a search for battery problems, there are so many damn bits of info on battery calibration it's unreal, first rule of forum.. "search before you ask"! Nappy change anyone?!

I did a search but found nothing regarding this issue.

Sorry to bring up an old thread, but i have just recently gotten the same problem.
It started after i installed the 2000 Mah samsung battery. I have since calibrated the battery but the problem apperently still persist.
I have several chargers, and i'm beginning to suspect that the one in the bedroom doesn't work properly anymore. I used the charger in the living room to charge to 100% calibrate and it stayed at 100% when unplugged.
Any ideas or suggestions or is it simply still af matter of a bad calibration?

When unplugging, anything in the range of 95% to 100% should be ok.
As for calibrating, i usually drain my whole battery to 0, then recharge to get back 100%

That is exactly what I did as well.

Another way you could fix this is by turning off auto-sync while you charge.
I had this exact problem, but it is caused by your phone completely charging, when it gets to 100% it stops taking battery from the plug, so its using your phones battery. Auto sync is always been used and uses a lot of battery.
Try this and let me know

Strange battery loading behaviour?

Hey Guys,
in the last few days I noticed following strange battery issues:
When I go to bed in the evening I plug my phone to the charger,
in the Morning I have a green LED and battery is at 100%.
A few minutes later the Battery has a massive Drop from 100%
(From 100% to 58% or 100% to 38% or 100% to 61%)
After I noticed this, I installed Current Widget to log the battery
consumption.
Here is what the Log says:
2011/06/22 02:16:15,64mA,99%,4.205V
2011/06/22 02:18:20,56mA,99%,4.205V
2011/06/22 02:19:39,54mA,99%,4.205V
2011/06/22 02:22:00,50mA,100%,4.205V
2011/06/22 02:23:00,48mA,100%,4.205V
2011/06/22 02:26:04,-104mA,100%,4.175V
2011/06/22 02:28:12,-104mA,100%,4.175V
.

.
.
2011/06/22 08:24:33,-48mA,100%,3.874V
2011/06/22 08:25:34,-78mA,100%,3.874V
2011/06/22 08:26:34,-46mA,61%,3.869V
2011/06/22 08:27:34,-154mA,61%,3.869V
Two whole Logs can be seen here: http://pastebin.com/yfzBcJk3
So my question is:
Why is the battery depleting between 02:26:12 an 08:24:33
while still plugged in?
Is this a Bug?
How can i fix it?
At the moment im running my IncS on Android Revolution HD 1.0.2 ROM
(I have noticed this also with 1.0.1 and Unitiy Kernel...)

It's not a good idea to leave the phone pluged to the charger. When its fully charged i always take the charger out.
There is several threads about that, e.g. this one.

same here m8
but i found, that cause is Current Widget. Uninstall it and everything gonna be ok. if not - install Power Tutor and find the way your power disappearing.
i have around 1% battery drop every 2 hours and 30-40% with Current Widget installed. (on stock and Android Revolution HD ROMs)

Erm ... when I am asleep I wont plug out my Phone, because, well I am sleeping

Well if you read through this section, you will see a couple of threads with this discussed.
The issue you are facing is common.
Once the phone is completely charged to 100%, the phone automatically stops drawing power from the charger.
So lets say you start charging your phone at 2:15, it may charge up fully by 3:15.
Though it is still connected to the charger, the phone stops charging once it reaches 100%.
Then the phone starts drawing power for its normal usage, standby, display, any apps running in the background etc.
So by the time you wake up at 8:15 (or wenever) the phone wen connected will still show 100%, but after unplugging in a couple of minutes, it will drop down to the actual battery percentage.
nothing wrong with the phone.
i noticed the same with my earlier x10 after the 2.1 update as well.

Nice explanation! Always wondered what was going on here. So key is not to charge it over night?

well, key is to charge it as long as required.
Once it reaches 100%, any additional charging is a waste of electricity

Good point! Do you know if the phone's alarm still works when the phone is off? This was the case for my old i8910 hd and was quite handy for saving battery at night
UPDATE: No it doesn't!

Battery won't charge to 100%

Hi
I'm new and this is my first thread.
After I rooted my phone I have an issue with charging my battery.
When I started the phone after the root I had a 100% battery, after I was playing and using it I plugged it in when I was going sleep.
After the whole night my phone charged from around 12% to only 60%, and then after I was using and draining the battery nearly to minimum(around 5-7%) it and left it for a couple o hours and it charged to 59%. Sometimes it charges a bit more but the whole process is really slow comparing it to the stock rom charging(it was taking lik 3-5 hours from 0-100%).
I rooted my phone with ivendor's rom from this thread:
http://forum.xda-developers.com/showthread.php?t=1825260
I was using CWM 6.0.1.2.
I would like to ask for any solutions for my problem, for now I want to drain it to 0 and then leave it again charging for a couple of hour maybe a whole night.

It's a bug. Sometimes is occures and sometimes not.
You could flash castagnaIT kernel and try again.

Just installed the kernel.
1st thing I noticed is a performance increase.
I'll gonna post what's the situation of battery tomorrow.

Ok, After a whole night of charging my phone only got to 68%, then when I was charging it when it was turned off It charged to 85% and when I turned it on it stopped to charge even with the AC plugged in and the icon is showing that it's charging.
Any solutions ? Please help.

I get a similar issue. When on stock I was always getting 100 %. Then I flashed CM9 and I randomly get 100 % after all night recharge.
If you are not afraid of switching ROMs, try a different one and let us know if it solved the problem because as mrjraider said
It's a bug.

Ok.
I was charging it turned off. It charged to 100%. I'll gonna test it today one more time with charging it when the phone is switched on.
If it fails I'll gonna get back to my stock rom and test it and try again with a battery charge to 100%.

Also remember that the phone wont charge completly due to safety of your battery..
Most of the time it recharged to 98 percent

Yes I know but the indicator in the phone 'has that in mind' so it shows 100% but its really 98 i know. When I was analyzing that battery graph I saw that the battery is charging really long. If I'm reading it right it takes the same amount of time to charge it as to drain it when using it.
Screen is attached. I was charging it through the wall charger.
It's polish language
Any opinions ?

Make your battery empty 0% !
Try to turn on the phone after empty battery !
and make sure that the battery is empty ....

I think that the solution was USB debugging. When I turned it off the phone is normally charging full and works perfectly.

Hey everyone! we are all using a li-ion battery » when we unplug our device from cable it will turn automatocally to 99%... I'm sorry folks, i don't like this feeling neither never havimg 100%...

Try another rom. It was the solution in my case.

Ahh.... just turn it off. Charge it fully( 3hrs at max). Got to recovery and wipe battery stats. Then drain it completely, and then recharge it fully.again. Then it will most probably go till 100%

Xperia Z battery behaving crazy, tough to charge it.

Hi everyone,
Since few days my Xperia Z battery is behaving crazily. It goes up and down. Sometimes when I disconnect the charger, like say at 60 percent, it suddenly goes up or goes down and when I again reconnect the charger it again goes back to 60 percent. Sometimes it doesn't charge only. Sometimes it starts charging, then all of a sudden it stops charging then starts by itself. :/
What's wrong with my device, I don't know. Need help.

Maybe you should try to charge it fully while it's off? Might not do anything but it might help You might just have a damaged/faulty battery.

Well, sometimes batteries just give out and start acting weird. How long have you had the phone? Sometimes as your battery ages, it just starts doing weird thing's. Wouldn't be a problem if we could change the battery

Give out within 7 months? Yeah, wouldn't have been a problem if we could change batteries. But that's the sad part of the story.
I am thinking of switching to Note 3 now. Charges fast, has a bigger battery, stays long. That's exactly what I need.

faster charging kills battery faster

Hi There, this may sound stupid but have you checked the lead/charger, is it an aftermarket one? I have also had similar probs but it was the conections. also try a system wipe and a full charge. and wait for the phone battery to fully flatten then repeat. always charge past 100 percent if you have installed a fresh rom or done a system wipe.

fast charging plus over charging or charging while using the phone= super kill battery

This is true, however sometimes the battery can indicate it is fully charged when it isn't, ( battery stats can be wrong ). I always leave my phone on charge when I sleep and have never had any probs my xperia t is now about 18 months old.

Thanks everyone. I guess I have somehow damaged the battery way too early. I used to use it while charging also. May be the reason of it's present Behaviour.
Right now I am not letting the battery go below 50% and have found out that it stays good, charges, no hiccups
But as soon as the battery goes below fifty it starts behaving too badly, takes time to start charging.

I'm so paranoid about using my phone while it's charging I avoid it as much as possible.
Since you've only had it for 7 month's or so, you should still have the manufactures warranty. You should send it in for service. I had a problem with my old ZL last year, and I ended up getting a new phone.

[Q] Phone is using too much energy to charge?

Morning,
since a few months i occasionally have this problem. My phone is charging slooooooooow and i get a message somewhat like: your phone is using too much energy to charge, try closing apps blabla.. (freely translated from Dutch, sorry). Sometimes this happens when im going to sleep. I dont notice its not charging normally, i go to sleep but when i wake up the phone is turned off and charging while turned off. This way, the alarm won't go off either and this may lead to some problems sometime in the future I didn't happen yet when i had an appointment or something fortunately.
First i thought it was a rom problem but whatever rom i'm on, the problem keeps occuring every now and then. Just last night my phone was at 2% and it said that it needed 1 day and 13 hours more to charge This morning i just let the phone die and now it's charging while its turned off. It seems to charge somewhat faster now.
I read different topics on this subject but there wasnt really an answer to this problem, most of them just updated or changed rom and the problem was fixed. I'm wondering, is this a battery problem maybe? Or maybe my charger is malfunctioning? I hope someone experienced this before and found a solution.
Thanks in advance!

So after 2 hours of charging it was on 47%. I thought lets try to connect it to my computer: suddenly its on 69% Then i got a message to connect to original charger cause this will take longer to charge etc.. so i plugged it back in the wallcharger and its on 67%.. Wtf is happening
edit: Its charging to 66% now LOL
