I have decided to move this post from the issues thread to a dedicated one to give it better visibility. If no one else is getting this problem then I will probably return the device.
I have the excellent "devstate" today plugin application installed which gives the battery charge level in 1% steps. When I say slow, it takes around 3 mins to increase by 1% which means it will take 4 hours for 80% charge (too long) when this is the case, the back doesn't heat up.
I have seen it charge much faster on one occasion i.e. around 1% a minute and the back was warming up (this is logical if more current is flowing) I was wondering the cause of the slow charge is that the device thinks it is connected to a pc and the charging current is limited. Also when you plug the cable sometimes the menu pops up asking whether you want to enter activesync/disk drive mode but doesn't on other occasions. There doesn't seem to be any pattern to it.
Another observation is that a soft reeboot occasionaly gives wildly varying battery levels for example before reboot the charge might be 100% and straight after the reboot 90%, or 83% before and 100% after. Interestingly before turning on the device for the first time I fully charged the battery, but up on boot up it was reporting 60%! (maybe it didn't charge at all when it was switched off and 60% was the initial amount of charge the battery came with) Have I got a duff battery or some issue with the device itself?
I seems like the battery charges fast up to 75% at around 1% a minute but then slows down to 1% every 3 to 4 minutes. Maybe this is the charging profile for this battery. Has anyone else noticed this?
Here are a couple of threads from the diamond section regarding the sort of issues I am experiencing but there doesn't seem to be a conclusive fix.

Could people please answer the following questions to help me decide whether I have a faulty device/battery or some ROM issue which all of us have. I have the stock UK touch pro ROM 1.90.405.1 WWE.
1) If you fully charged the battery before powering on for the first time, what was you battery charge level immediately after power on?
2) Have you noticed fluctuating charging rates?
3) Soft reboot gives different battery charge levels.
Just a quick Q, which charger are you using? Can you just post the amp / volt data printed onto it for us?
I am using the one that came with the touch pro, model no TC P300, its output rating is 5V at 1A. Input rating 100-240V
I have also tried the mda vario III charger and I get similar results i.e. fast charge up to 75% then slow afterwards.
As i stated in the other tread with the "Raphael issues" i have the same problem.
When i use the shiny new charger with the "usb-mini usb" cable i takes 7-8 hours to completely charge the device. (output is 5V-1A)
However, when i use my good old Hermes charger, or any other 5V-1A charger, it goes to 100% in about 3 hours.
Mine charges up to 90% from 10% in less than 3 hours after which it stays @ 90% (According to the built in battery meter of the device) forever. Is it a faulty battery or its supposed to be like that?

And do you get varying battery levels on soft reboot?
3 hours is probably what I would get i.e. "75% at 1% a minute = 75 mins" PLUS "25% at 1% every 4 mins = 100 mins" giving a total of 175 mins.
question is that is this behaviour normal for touch pro or only present on
some device/battery/chargers.
I also have another issue, this time regarding interference on speaker, see this thread:
http://forum.xda-developers.com/showthread.php?t=419761
If only my touch pro has these faults then I want to replace it asap, especially when having paid £500 for it.

Yes i do get varying levels on reboot, but i got that with my Hermes and Magician too. So i wouldn't worry about it. Usually when you softreset while it's charging you get a higher battery reading then you should have, but it wil drop after some time to it's real level.

This happens when its not charging. I don't get this with the vario III. Maybe it is ROM dependant. The other concern was after having charged the device fully when switched off, it reported 60% on power up. I might let the battery drain to a low level then charge when switched off to see whether it charges at all. Some diamond owners were also reporting this.
Hmm, got the same thing tonight with my Hermes charger, has been charging for 6 hours and still not fully charged, now at about 80%. Very strange. Are there more people experiencing this?

This didn't appear to happen to me on the first charge, but I turned it on immediately after putting the battery and SIM in place, and then I charged (I don't remember what the initial battery charge was). I've not noticed such wildly inaccurate readings after reboot either. I haven't specifically checked for inaccuracy in the battery meter, but I would (probably) have noticed such a big difference.
Have you tried to do a full discharge and charge cycle? This is necessary after around every 30th charge to recalibrate the gauge so that it is as accurate as possible. I know yours probably haven't gone through 30 charges yet, but it may be worth trying.

This is normal for lithium-ion batteries. The last 20% or so can take as long as the first 80% to charge.

When charging I usually leave mine overnight, so I think I've only charged it once during the day, and then I think this was through USB while connected to the PC so it may have been a bit longer than 'normal' (3-4 hours) for that reason. I'll keep an eye at it next time I do it during the day.
Six hours plus sounds far too long though, do you have a chance of trying the battery in another device, or another battery in your device?

Nope, don't have a second Touch Pro around here, but this is really annoying, I need a fully charged battery in the morning. If this is hardware related i'd return it to get a replacement.
hmm, this is interesting.....so just to clarify we are seeing slower charging with the bundled adapter: which is essentially an AC to USB power transformer?? If the USB port on that (yes i know its power only) is capable of supplying only a standard ammount of juice then your battery may charge to 100% as slowly as from a pc or car charger..
..id like to perhaps see if i can meter the current and voltage coming from it but would need me to cobble together a breadboard with the relevent power points.
Is the hermes / kaiser charger charging it fully in less time?? (to clarify)

Yes I drained the battery till the phone switched off by itself but still have this problem. I suspect there is a problem either with the phone itself or the battery as supposed to a ROM issue. I thought all the clever charging circuit is in the battery these days and it's the battery which reports it's charge level to the device too. If this is true then probably the battery is faulty but I am not going to buy another one just to find out. I'll try to get a replacement for the touch pro tomorrow when the shops open.

It is, but even so the gauge (in the battery) needs recalibration once in a while, hence the full discharge/charge cycle every 30th charge or so (other than that it is recommended to charge li-ion batteries often, and not deplete them fully).
Your next port of call is probably to see if another battery makes a difference.

Today I charged my phone from empty to full while connected to the PC, which took around 3 hours 30 minutes (phone not used except to check charge levels towards the end).
the charging cycle on mine has been a little erratic too.
I put it on charge at 9pm last night, at 6.30 this morning it was at 88%. 9 hours and not fully charged!!...still, 3 hours later and it's on 87%. so I think its more a case of requiring a few charge/discharge cycels to settle the guage down a bit.
This night it fully charged in 5 hours. While yesterday it wasn't completely charged in over 8 hours. There doesn't seem to be a pattern in this.
Yesterday it was showing 48% battery level at one time, a soft reset later 28%, another soft reset and it was 24%. Today I have sent it back for a replacement. Can those people affected by this issue please state where they bought it from, in order to figure out whether it might be a faulty batch. I bought mine from clove technology in the UK.

Mine came from Expansys.be, please let us know your new unit has the same behaviour.
Will do if I get a replacement one, they have satisfy themselves that there is fault first. Will probably take around 3 days. I miss my touch pro already.....
Oh well back to the vario III for the time being, seems cumbersome already in comparison.
Hermes Charger

Whilst I don't have any exact figures to hand, my hermes charger took about 45 mins (Give or take a little.)
I've been using the standard Raphael charger today and charged from 50% and it's still going after 1 hour 20 mins and only at 90%
I know the final 80% takes a lot longer, but even so.....
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.

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.
I mistakenly posted this in the wrong forum at first, so here it goes again:
I bought this Galaxy Tab 2 10.1 (GT-5110) about a year ago, it runs the original firmware with the recent Samsung update to 4.2.2.
Lately the battery life has become very short. This was not a gradual change, but something that seemingly happened over night. I charge the device with a travel adapter that claims to output up to 1 A. The battery monitor shows that charging works as expected and the device charges to 100 % .
In use the battery shows 100 % for a while, but after about 20 to 30 mins jumps to 4 % , giving me the low batter warning. I am travelling and the only change I can think of is, that mains power here in Canada is 110 V instead of the 220 V back home in Europe, not that I expect that to be a problem.
I don't notice the device getting warmer than usual, so I don't believe, that the battery really charges to 100 %. Is there anything on the software side I can do to investigate this further?
Thanks for any advice!
EDIT: I just noticed, it's actually not the battery, that is dying. It is a error in the measurement. The battery life is normal, however the charge measurement shows nonsensical behavior: It goes to below 10 % in less than half an hour and then goes back to full, repeating this in cycles, like a sawtooth wave. So I suspect either a hardware fault in the measurement circuit or a software problem.
Here's a screenshot of what the battery info looks like, mind you the device has not been on the charger the entire time:

i think the problem is with the charger
drain the battery of your tab completely and then charge it fully upto 100 % with stock original charger and see if you notice any difference

What makes you say that? I've been using that charger instead of the Samsung charger at home for a long while now.
For me it may be the hardware issue, because software doesn't consume battery in the background so rapidly.
#If you are not sure try this options
For Hardware issues:
*Make sure your charger is working properly (Completely drain your battery and then connect your charger and charge for few half n hour and then reboot your phone and check your battery status and use your tab normally for few minutes and keep an eye on the battery consumptions)
If your battery is gradually decreasing no fault to your charger.
If your charger doesn't charge then its the time to either change or repair your charger.
For Software issues:
"GO TO BATTERY SECTION IN SETTINGS AND CHECK WHICH APPLICATION REDUCES YOUR BATTERY OVERNIGHT RUNNING ITS SERVICES IN THE BACKGROUNG AND JUST DELETE IT"
*After using your tab normally go to SETTINGS>APLLICATION MANAGER> and then RUNNING SERVICES.
If you find unnecessary services running in background NY an app which is not required just uninstall those app.
*Try to check your Sync, WiFi, GPS etc. settings to ensure that any app is consuming continuous services and draining your battery.
*Remove recently installed app which are not necessary.
Hope they help.
Thanks so far, I just updated my original post to describe the problem more precisely.

I had this exact problem, down to the sawtooth battery status profile, tablet model and android version, and fixed it with the following procedure:
After a normal boot, press and hold the power button continuously.
The tablet will shutdown and reboot repeatedly.
Hold the button down for at least 4 complete shutdown/restart cycles, never releasing the button.
After that treatment the battery status shows a nice, normal discharge curve, starting from whatever random place the sawtooth pattern left you at. Run the tablet until it powers down by itself, and then recharge it.
The ugly sawtooth battery status first appeared on the tablet after running an intensely power-hungry application (the battery got hot after 20 or so minutes of running). After that, the discharge rate seemed to have a flipped sign, where if normal discharge rate per minute was positive, the altered, aberrant discharge rate was negative. CoPilot was the offending software; however, that may be a post hoc ergo propter hoc logic error on my part.
The messed-up discharge rate would prematurely terminate charging if the table was on, so the only way to get a full charge was to turn the tablet off and attach the charger.
Basically my Google pixel has been having these issues since January/Feb
But the phone refused to fully charge it would stop at 98% and the battery wouldn't last long at all I used to get 4h screen on time and have like 20% left now I get 2h 22m with the replacement device that Google gave me.
I have had the device replaced four times, yes four. And I have tried to charge the device with no data on it and no email. So it would be a fair test.
With this, the fourth device, it charges, then reaches 100% then depletes while in the charger and not being used and so it has 97% after.
The device lasts no where near as long as it should and when I take it out of the charger in the morning it drops from 97% to 92% with 5 mins of use.
Google are now telling to replace it again. I am using the official charger.
Someone please advise me!
This is happening to my Pixel too. Also when battery has like 25% left, the phone suddenly power off, and it won't turn on until i charge it. When it boots, the battery indicator shows 1%. Truly weird. Idk if it's a software issue, a battery issue or wth is it. Hope somebody has a solution
Both of these sound like bad batteries.
@Zikohh, you're probably being given refurbished phones as replacements, and they don't have a new battery. I recommend you suggest them to pay for a battery replacement, rather than change the device again.

Two things try to update (may security update) and if not any better and you haven't already - try a factory reset my camera app caused similar stuff and a factory reset fixed it. But if you tried once don't bother just try updating it.
Hello. I just noticed something weird on my TCL 10L phone. When the phone reaches 100%, it displays fully charged on my lockscreen. Though, unlocking the phone I see the phone is still charging. I see the battery bar being green with a charging bolt. It takes around 15-30 minutes until it says charged (and the bolt removed). Is this normal? I do not remember the phone doing this when I bought it around 5 months ago.
Changes in charging and especially sudden loss of capacity can indicate a battery failure.
Check for cover swelling/bulging, battery swelling is a failure, replace asap if so.
A failure this early is rare but Li's can fail at any time in their life.
Inspect jack and port for contamination. Use a known good charger and cable. Try cycling the battery until the phone shutdown then charge to 100%, repeat... to calibrate battery indicator.
Minimum start charging temp is 72F
Best start temperature is 82-90F
Never attempt to charge a Li below 40F
Keep battery temperature below about 101F when charging.
Do not use phone while charging as it will skew the charging curve.
Thanks for the reply. There is no battery loss. I can play games on this device, browse, and check apps and drain the battery in the same period I did since I got it. I actually charged it to 100% since went to sleep. 9 hours later the device was still at 100%. 1.5 hour of playing a game after that and the battery was down to 84%. The issue is really weird. I am thinking a battery calibration may help. I do not know.
P.S. I am currently using Android 10 and I do not want to switch to Android 11.
I wouldn't worry about it.
It's best not to charge to 100%.or below 30%.
Lu's like frequent midrange power cycling (40-65%).
As for 11, no way that crapware is getting on my phones....

Did you personally experience this on any device? This is the first time I saw something like this. According to some articles the phone may display wrong battery stats. So I was thinking calibration would be a solution to this issue.
