[Q] Says 'not charging' but slowly charging - Galaxy Tab 2 Q&A, Help & Troubleshooting

My dad owns this old Samsung galaxy tab 2 10.1 and it died today day. It did not charge at all (i thought the cause must have been from the battery charge dropping too low and dying) and so i decide to do some DIY teardown.
Opened it successfully without damaging anything and saw the battery inside. I unplugged it and read a charge of 3.05 volts. This was really low but i knew due to some previous experiments, this was enough to make the tablet work. I put it all together and plugged in the charger and the charging logo magically popped up (maybe produced a small reset).
The main issue is that the tablet says it is not charging in battery settings even though it is (after 2 hours, went from 9% to 13% and later on from 16% to 19%. I think the battery is just damaged. Is there a way to fix it or should i just buy a new battery for it?

[Q] Charging and battery indicator

Hi everyone
My problem is.. my DS started to charge slowly.
Now it doesn't really charge slowly, If I check the voltage, I will get like 4220mv but as soon as it reaches that, the charging graph just goes flat.
If say I have charged it to 70% and it started going slow. i switch it off, place on the charger, and the lamp goes green. I turn it on, and it is showing 100%.
I have tried calibrations, diffirent kernels, wiping, factory resets e.t.c.
Another thing is that if I will run a v6 battery calibrator,it will show that actually I should have a 100% charge although a phone is showing only 70%.
So the summary: Phone charges normally when off (when recovery monitors charging), showing the correct voltage when on... But showing the wrong percentage if on charge.
Also sometimes if the battery is like 14% left. And I turn the phone off and then on again, it will show 22% bearing the same voltage as when it was 14%.
Question: Is there any way to tweak the battery indicator so it would show % values same as the v6 calibrator does it or is it a hardware fault, if yes, which part of it ?
This happens to me on my older (original) battery, but not my new one. I bought the second battery when this problem started happening. So, I think it's just a symptom of an old battery.
By the way, if you leave it on charge long enough, it will eventually jump up to 100%.
Other than this weird behaviour, it has no real impact on anything.

Thought so, mines been acting similarly lately, but strangely enough it seems to be getting better
I think I found out..
I actually purchased a new battery recently, because my old one was jumping like crazy and started discharging in a few hours..
This new battery I bought from a mobile repair shop.
It is a cheap chinese battery with no name, anyhow I just took it out to take a look at it...
And guess what, it sais 1200mah..
Can the phone be confused because of that ?

[Q] Battery temp too low and not charging

Hi All,
I have this problem of the tab not charging,
Was searching all week and had no luck. Seems like a common problem among phones especially on SGS and SGS2.
When it was on , it showed a message saying charging paused Battery temp too hot or cold.
Now the battery is drained, and when charged to the mains, it would show a yellow triangle, and a thermometer.
See picture attached..

Just wondering if anybody had any luck figuring out why this is happening and any work around?
Just to rule things out, Tab had not been in any wet places...
service manual
I was going through the service manual and it was saying,
"If the battery will no longer charge, completely you need to replace it with a new battery. Take you device to your local service centre.."
Thoughts?..

Well first if you still got factory warrenty...
get it fixed by samsung...
If you want to save a few dollars you could attempt to pry the screen out from the back cover and charge the battery externally then if thats a NO GO buy another battery online and then put it back together.
Ive read before with charging problems that if teh battery gets completely Flat it wont have enough charge in it to activate the charging circuits.eg when you plug in charger you get black secreen and no battery icon,you need to pop the screen out and remove the battery and charge it from a external source.then replace it.
Never seen anything about your particular problem though...
I will enquire to Samsung, not expecting much because, tab7.7 was never officially launched in Aust.
Ho do you go about charging, externally?

Try plug in wall charger for 30 mins then hold power button for 15 seconds.This is good for waking it out of deep sleep and getting it to trigger charge.
another thing is possible fix from factory reset in twrp?
i would try a few things like this and leave opening it up as a last resort.
for your info google how to open up galaxy tablet and you can find pics
how to prise the screen out of the back cover.ive bought tools for this but havent done it yet as worried about damadging screen or cracking it.
there are clips around it and you have to pop the clips out.
Australia samsung probly wont fix it as not australian model..
another thing to ry is charge using ipad 2ma charger...
Experienced exactly the same issue in May 2013. It was functioning well and charging without problem all along and suddenly turned out like this. Tried different method to have it charged but no luck. I have to bring it back to the service center for repair finally.

Did the Samsung guys tried to explain anything about this?
What did they replace? Did they just replace a battery?
Please let me know.

Galaxy GT-N5110 Note 8.0 - Charging paused...battery temperature too low...
I purchased a Galaxy Note 8.0 (GT-N5110) last July. It's been working great until yesterday when a window popped up stating "Charging paused. Battery temperature too low."
I tried shutting the Note down and charge the battery whilst turned off. It seems to be charging just fine at the moment. Will check it in a few hours when the battery has been fully charged.
I installed an app called Battery Monitor Widget. It's reporting that the battery temp is around -2c to -4c while charging.
UPDATE: Battery is charged @ 100% and the Note is still on AC power. Battery Monitor is reporting that the battery is -3.7c then to -5.9c...
My next test is to completely drain the battery and see about charging then.... Will keep you posted...
Can't post screenshots for now...
Skol!

UPDATE: Now on battery, the battery temperature is reporting at -4.7c...
I some how fixed it by accident..
First I thought it was a faulty battery only to realise that replacing the battery did not work...
Next I followed one of the remedies I read where it said to connect the charger to the unit with the wall charger connected and connect the battery (there is a ribbon cable).
Some how it worked. Started charging etc.
I noticed that the battery had full charge as I had it plugged in for a whole night before when i was experiencing the TEMP too low symptoms.
It seemed as if it was charging all along but was showing that stupid error on the surface...
Hope this helps some people.

Have this issue with one of my S4's (fortunately I have a couple so can swap things about)
The phones had a life of luxury on my desk, except it suddenly started reporting 'battery temperature too low' issue and not charging
The same battery in another S4 is absolutely fine, so the battery itself is ruled out (and indeed 2 other batteries will not charge in the unit having problems, despite working fine in other S4's)
It seems that something has died in the S4 itself internally. and is likely going to require replacement/fix at a service centre.
How many other people have this? - it could be an issue with the device build.

[Q] slow charge, fast drain, hot batt, jb update

​ Hi guys
I have a galaxy s relay 4g
It took 2 hours of constant usage, to kill the battery from 50 to 0%
Figuring this was normal, I was configuring everytthing while downloading 50apps over wifi
Note phone was on airplane mode, but wifi was on.
Next day I updated from stock ics to stock jb
Turned it on, it was at 91% and after 5 min of usage the phone said it was too hot to charge the bat.
Phone went from 91% charge down to dead with one hour of moderate usage and 2 hour siting idle on airplane mode, wifi on..
It was 46c on batt temp whole time
Charged for 3 hours from pc usb and it gained 3%.
Charged another 3 on wall socket that came with nokia lumia, rated at 1400mA.
Charged 15%
The battery info showed that even though the phone was off, it woke up many times during the night -- IT WAS OFF as in the battery with the 4 white circles on the bottom were showing!
Turned off, removed sdcard, factory reset (left sd out, its still out) i
Came back ok, it syned to google and reinstalled all my apps, then died again
I've tried 2 batteries, and 3 different chargers,
I factory reset the phone too.
Wake lock says the android system used 18% of the battery... other than that I can't see anything obviously wrong
Stock on any device is also resource hungry.... What are the specs of the chargers you are using...certain chargers will not put out the needed amount of ma or volts...which also messes with a Samsung battery overcharge feature
Sent from my SPH-L710 using Tapatalk
Charger 1 is my pc usb port, which charged my other two phones (mytouch q by lg and sammy captivate glide) about 70% as fast as charger 2.
Charger 2 is what came with phone but doesn't appear oem. 5.7v at 600mA
Charger 3 is the oem charger which came with wifes lumia 925 which rates at 5v at 1400mA
Its "charging" in my car now, no sim card, wifi on and connected to a medium strength signal, 0% charged and I wached the voltage steadily decline as I hit refresh in the gsam battery monitor. Started at 3.3v and in a minute was at 3.18v. Still 0%
Car charger is a no name brand (which kept my captivate charged pretty well despite using gps at the end of my 6 hour drive the phone was still at 75%.)
The battery is samsung oem.
The first battery I tried is also samsung oem.
I also have a 5v 1amp charger that will fill both phones between 1 and 2 hours if memory serves, the 1.4 doesn't seem to go any faster as I guess the won draw much if any more than 1 amp.
Given all of the above I'm inclined to think its software or other hardware issue.... phone was sold as "seller refurbished" on ebay, but the description says its just an open box sale of a phone that came back within the first 7 days....and yes I bought a square trade warranty in case some BS like this happened.... but want to try and fix before going that route.
Is there no way to factory reset to the original ics firmware?
I see you also have a relay, once I get this all figured out id love to root and rom mine like you have yours!
I know the newer android roms have more features but are they more or less responsive in general?
Main reason I got a relay instead of another captivate glide is the relay has much more rom development.
And now the red charging led isn't even turning on..... I wonder if its defective.
Shame I can't return it now, the screen has light scratches (was in my pocket while I was working under my carL
And it was sold in like new condition
Grabbed a brand new USB cable plugged the phone into a 5th charger, oem HTC radar, 5v at 1amp
swapped the battery for the 1st one I had.
Appeared to charge fine. Pulled out the charge cord at 50%, plugged it right back in.... the battery charging screen went from about 50% down to 20% in 1 second.
Confused, I left it plugged in and went to bed.
Got up this morning and it was dead again.... while plugged in, while off, not even the charging led was on. switched to the 1.4A charger, still nothing... hit the home button a couple times and the thing woke up into the battery charging screen (it ignored the power button the whole time)
The gsam screen was even more interesting:
it doesn't show much but the line graph showed a rapid decline from 20% down to almost 0 from some short time before 3 am, then
3 hours from 3am to 6am, the charge went from near 0 to 50%, and then in half the time back down to near 0.
The temp graph wasn't a line, but fragments of one
does Gsam show the amperage of the draw or charge on yours? its only ever given my the voltage of the battery and shows 1mA on the bottom of the battery,
ebay seller says clean the charge port with alcohol.... not sure why someone should need to do that on a "like new" phone but I'll have to try and find something tiny to shove a paper towel in there with..... that would account for the not charging but not for the high drain.... could thins thing have a short someplace?
sounds to me like a defective device. the fact that you did a factory reset and it's still not charging even with it turned off is probably the biggest sign there. it can't be any apps you've installed because you wiped them all off. i think you've gone way above what should be normally expected of a customer in terms of troubleshooting your device. hairline scratches on the phone are fine. you should still be able to return/exchange it IMHO. especially with the squaretrade thing.
yes, it's possible to flash back to stock ICS but if it's not working with the factory rom (whether ics or jb) the phone obviously has issues.
i just bought mine a couple weeks ago too, though not over ebay. i found a local tmobile "authorized" store (advertising on craigslist) that was selling stuff with similar description - open item or customer purchased and returned within a week. i have used mine on all sorts of chargers without issue: a motorola dual-usb rated at 750ma in the car, a monoprice 2.1a charger built into the 10-outlet power strip at my desk, 2 different laptop usb ports, and a samsung wall charger rated at i think 1.8a which came with my wife's galaxy tab 2. i never ran stock rom for more than about a day or so, just to verify proper operation of the phone, and now i run cyanogenmod11. i can go all day on a charge with what i consider medium to semi-heavy usage, which i think is great.
for example, yesterday i unplugged at about 9am after an overnight charge (with the phone on - i almost never turn it off because i have to be able to receive on-call alert emails from work). i got the day started in the attic installing radiant barrier (so it was rather hot). i had the phone in my pocket streaming a shoutcast station over wifi for probably about 4 hours. later, i watched a 30 minute show on netflix (also wifi), played some wordfeud, surfed the net a bit, watched some youtube videos on fixing my weed eater, did a few emails for work, probably 20-30 texts and maybe 10 minutes worth of phone calls. by 11pm i was still around 30% charge remaining. at no time did i plug in my phone during the day.
i have an extended battery on its way from china, so i expect to be able to go 2 full days on a charge with similar usage. and the thicker back plate will make it easier to hold, since i have such long fingers.
tl;dr - you got a bad phone. exchange it.

Galaxy S6 O2 Charging issue

Hi All
The battery died on my S6 tonight with the indicator showing 13% (unlucky I know!). I plugged the phone into my wall fast charger and went for a bath. When I came back down 30 mins later I picked up the phone and it was showing 0% but in the notification area it had recognised the fast charger and said 1 hour 20 mins to full.
I changed the USB lead from the charger to the phone and initially it charged up to 30% in around 15 mins and then immediately dropped back down to 0%.
I have again changed the USB lead and it seems to be charging again it has made it up to 42% this time without dropping so I'm hoping it fully charges.
Does anyone have any advice or has anyone had a similar issue?
After this I will NEVER buy Samsung again I've had nothing but trouble with this model I really don't think its fit for purpose.
It is sold as a multi media device but if you try to use it as one you need to carry external battery packs. When I took it back to Samsung they said its a "screen on issue" and the screen on time is no more than 3 hours.
***************************************************UPDATE*************************************
It now appears to be stuck on 42 %

I've had similar issues like this but I am rooted. It involved me doing a clean install of my preferred rom. If you are stock then try the following 1. Factory reset 2. Flash a firmware via odin. If you still have issues then try a new usb cable and charger. This issue has only ever happened to me once since I've had this phone last September.

note edge battery problem

I recently realized that something is so wrong with my note edge. It suddenly shuts off by itself at 15 - 20%.
I have an old extra battery and do the same thing at 5%.
I have perform factory reset and charge the phone while turn off, nothing can do.
I bought an extra battery (not really sure if it is original) in ebay but did something weird. It wont charge full, it only charge at only 90% or arround. Even overnight charging and it still can not charge to 100% unless I take off the battery and place it again.
Is it cuased by marshmallow update? or Is it hardware issue?
