battery problem, please help - Galaxy Tab General

this morning when i unplugged my tab the phone was showing 81%. if i try to charge, the percentage doesn't move from 81%.
yesterday i installed an app called battery minder. tried to uninstall it but nothing.
could you please help me?
my galaxy tab is EUR with original JK5
thanks

When you say "tried to uninstall it but nothing", are you saying it would not uninstall or after you uninstalled it dod not change anything.
In the meantime ~ have you powered down the phone..... leave it for 60 seconds, plug it into the home mains charger and switch on.
After it completes it's recharge cycle, unplug and see if it has reset the battery indicator scale.

sorry for the misunderstanding. i meant "after uninstalling the app nothing changed".
thanks for the suggestion, but i hardresetted and now it seems the phone is charging again (i'm 87% now)
thanks

No problem......
Hard Reseting the device was a bit overkill. It was more than likely (happens often) that the battery sensor got into a 'muddle' and became confused.
Quite often doing the procedure I mentioned clears any error and resets the battery status back to it's normal use.

thanks. i'll keep that in mind

8525 - Battery: Unknown

Hi All,
I have a battery/charge/pda problem: if i look battery status i read "Battery Unknown".
If pda is plug to usb/ac it won't charge.
If phone is unplug, it show me a message that warns me the battery level is low.
I try another battery, soft reset, hard reset, change Radio Rom, change O.S. but the problem is the same.
Phone plug/unplug: always "battery unknown" in battery status.
Any idea?
Up! No solution? Any driver? Any tools? any... any???

This is a tricky one to solve.
Here is something to try, but you may need to try a few times and even then yiu may not succeed:
1.
Remove the battery from the phone for at least half an hour
2
Using the mains charger (NOT USB) connect to the phone and switch on the charger (battery still removed)
3
Now insert the battery. Give it a while (up to 5 mins) and hopefully the RED no charge LED will change to Orange and charging will start.
Repeat steps 2+3 if it does not work first time.
If all that fails there is one more fiddly suggestion where you charge the battery a little using a couple of AA type batteries. If necessary I can give a few more details on that.
Failing the above then you'll need to get another battery (preferrably pre-charged at least to some degree.

Hmm, I have a (mostly) similar problem to this:
My 8525 (WM6 flashed) wouldn't recognize my battery (when plugged in, status light still just flashes green) but the battery still seems to hold a charge (I've run it for a day with outlook sync enabled, which usually drains the battery completely). Battery status is Unknown.
I bought another battery and the same thing happens. Tried it on USB, tried it on AC power. The battery indicator always indicates "charging" which makes me think that my year+ of owning this phone has knocked one of the wire connections out of place. Any thoughts?
(edit: I should add that I tried Mike's suggestion above a few times and the result was always that immediately after inserting the battery, the red charging light went off)

Charging Issue

Has anyone ever had an issue where by their battery life is at say 59% and when i plug it in to charge rather than the blue charging icon appearing it just showing the battery being 100% and the LED doing successive double flashing as opposed to a static LED like i should be if it was charging?
I've not installed anything, flashed a new rom etc, was fine yesterday.
All i did was have a little play with CHTEditor.
somethings not right, it must be something to do with me messing about with CHTEditor
out of the blue my lock screen had gone, and it says i have a voice mail waiting when i dont. haha
Hard reset i think
update...
hard reset not worked...uhoh
Same problem here
I was in a phone call an al of a sudden everything just went black and rebooted. Turns out the phone stopped charging and flasing green and red. Battery ran out of power and the phone shut down. After the reboot the phone charged normally again
Another situation:
Phone started acting up again and endend in a reboot. Battery was empty and i made a phone call on the charger. during the phonecall the same problem happend again, but the battery was at 9%. I intended to unplug the charger and plug it back in, but after the unplug the battery jumped to 0% and shut down.
So, i think the battery is acting up. Having to charge the thing every damn day is finally taking it's toll.

yep, using the original battery, it seems to be ok now, charging as it should.
ahh well. cheers for the reply
one last this, how the hell to i get the lock screen back, i think im being dim.
edit
sorted
I have a program BsB Tweaks that has a setting for the lockscreen. Try that.
My phone is also charging fine when turned off, also it functions fine at the moment. i think it has something to do with overloading the device when the battery is low. Based on that its not possible to turn on any phone when the battery is in attached but the power is, i think everything is drained from the battery while charging it and that when overloading the battery just doesn't pull it anymore.
i don't have a alternative battery, mine is original.
What are the symtoms when the battery is at the end of it's life? does it do this, or is it supposed to give a warning or something?
edit: i am unable to find a manual page describing the different modes the LED could be blinking. I'm curious what is says about the red and green blinking mode. Does such a page exist?

HTC not charging after empty battery

This morning my HD2(7) was totaly empty. The power button did not do anything and the phone won't start up. When I hooked it up to the charger, the red led did not come up and the phone was not charged at all.
I tried to do a soft reset, but nothing happend. Some posts on this forum suggested a hard reset, but I did not want to loose all content on my phone.
It seems that the real solution is very simple. Just connect the phone to a charger, remove the battery completly and then place the battery back in the phone. The HTC will now start up and begin to charge.
So, just a waring, do not hard reset when you phone stops charging...
Cheers, Rene
Funnily enough I put my phone on charge last night, forgetting that I'd also switched it off... Came to it this morning and remembered about the charging issue when switched off. Tried to switch the phone on and nothing... So I went to change the battery with the wife's HD2, but managed to mix up the batteries and found that my phone would switch on afterall and it was also fully charged. The wife had her's on charge overnight as well, so both batteries were showing as being full...
Charging issue has been fix up in the MAGLDR 1.13 version

There is no doubt that this is sensible advice, but there may be an overlap with another issue here.
I have noticed - and it could just be specific to my phone - that if the phone gets to the point where it shuts itself down to conserve power, it will often not restart from the power on button and only pulling the battery will wake it up. This seems to be a 'feature' of WP7 on HD2.
Interestingly, on several occasions where the battery has been fully charged (and still plugged in) the phone will not start from power on if I do a shut down - I tried it less than an hour ago after making a couple registry tweaks and only pulling the battery would persuade a fully charged phone to restart. It would be interesting to know if others are finding the same.
Where the battery is seriously discharged, it can take several cycles of pull battery - boot phone - phone decides it has insufficient battery and shuts down - pull battery - boot phone...before WP7 decides it has had enough juice trickled back into it to be able to charge - sounds crazy, but there you go.
MAGLDR v1.12 doesn't support charging, which doesn't help. I'm going to try v1.13 to see if agarp is correct - here's hoping.
Update: I don't think MAGLDR113 supports charging directly but I believe it has something built in to prevent a plugged in phone running down the battery. Not sure about exactly what, but it suggests something about booting the phone if plugged in and battery is at critical levels.

[Q] Samsung Tab 7.7 - Battery Life & Warnings

Hi there, I purchased my 7.7 Tab 3 weeks ago. Loved it as expected. I've got few concerns about the battery though. Hope someone can share solutions / experiences with me.
The battery life isn't so impressive as I heard about from reviews and all. It lasts hardly 48 hours after a full charging with no real use for more than 30 minutesx2 times within less than 48 hours. However, it was connected to WiFi all the time and was syncing as well (but on standby all the time). Now another bugging problem is that when I plug the charger after the battery having completely drained and the device is turned off by itself (before completing 48 hours), the screen shows a warning logo first instead of the charging icon. The warning logo has warning sign and the icon of a drained battery with a red color at the bottom of it. I do not know what does that mean. I just know that when that appears, the device is not charging at all. I have unplugged and plugged it back 3 times to get it charging again. So far, it happened two times and I am sure it will happen again but I just want to know whether this is the sign of an unhealthy battery or any other parts of the device? This happened to anyone else? Your feedback is welcome and well appreciated.
Install SetCPU. :good:

sometimes... the cable is the culprit... a damage cable will gave the same error... btw.. it is not advisable to really drain the battery dry before charge it... but that just my opinion... just try to check the cable... and if there is anyone around you that having the same cable... test to charge your device with their charger...

First of all, you may not want to have left the battery completely drained, as this might damage the battery. Secondly, since your battery is completely drained, some undercurrent protection mechanisms must be activated, and there should have enough input current before the battery could be charged again. The data cable should not have enough current to charge up the battery at this state, it is lucky for you that you got it charging again after three trials.
If you drained up the battery again, it's recommended to charge it up with the AC charger.

Strange issue with battery charge

I have had my Nexus 7 for a week. First two charges went well. On the first one I plugged it when it had 5% battery left, and on second charge I plugged it around 10%.
However, two days ago I was reading something in Google Currents when the message reminding me that only 15% battery was left appeared. I kept reading for a few minutes (2 or 3 at most) and suddenly the "Power off" window appeared and the tablet shut itself down and wouldn't turn on again.
Immediately I plugged the charger, and after a few seconds it let me turn it on again. It said the battery was at 14%. At that moment I unplugged the charger again to see what happened, and the "power off" message appeared as soon as I unplugged the charger. Looking at the battery graph, at the moment I unplugged the charger the graph jumps from 14% to 0% instantly.
This time I let it fully charge while turned off, and the next day I tried to reproduce the problem. As soon as it reached 15%, the "low battery" warning appeared, and in a half second, before I could reach for the charger, the "power off" message appeared over it and the damn thing turned itself off again. It seems to me more like a software problem than a real battery problem.
I've been reading about people who had similar issues on another thread, but there was no solution. Has someone found a way to solve the problem? or you just exchanged it for a new tablet?
Thanks in advance!
Are you running stock out of the box or rooted?
You need to run about three full cycles through it, that means connect the charger and do not disconnect it until its fully charged. I would then unplug it, play around for two minutes, then plug it in again for about 20 to 30 minutes. Only do this bump charging when you completely charge it the first time.
After that initial charge and connecting it to top it off (bump charging) just use the tablet as you normally do until it dies.
Then connect it to the charger when you can allow it to completely charge to full.
If you're stock, either before the above steps or afterwards, use wugs toolkit and reset the stock image. Connect the nexus to your computer, copy the sdcard folder to your computer so everything on the sdcard storage partition is backed up, then install the stock image again which will wipe and reset the tablet.
From the information you gave I think its real likely that's a software problem and resetting will fix it. You can even try a factory reset in settings before you reflash the software.
Let us know the outcome.

I'm using stock, unrooted. I have not done anything a "normal" user wouldn't do. These first days I've been using it actively around 5 hours/day (i'm on holidays ) and I didn't turn it off until this problem appeared. I've charged it 10 times by now, and always made sure it was full before unplugging it. I have not tried the "bump charging" tho... I'll try it and report back
Thanks!
After bump charging it I allowed it to go down to 10% without problems. I hope it keeps running well now!
