Ok, I've been trying to get to the bottom of this problem for a long time.
I've got unilimited HSDPA GPRS on my Tilt, so I tether to my laptop. Kaiser is connected through a 1Amp powered USB hub to a laptop. Tilt was just lying on the desk, and I noticed several interesting things:
1. If Kaiser is at 100% charge - the green light (power) will stay on for a long time, about 40-60 minutes.
2. If Kaiser is NOT at 100% charge, it will charge (orange light) but won't reach 100%. It will stop charging in about 20-30 minutes.
3. If I put Kaiser on a cup, so that there's nothing under it and air moves freely all the way around the Kaiser - I get around 40-60 minutes of charging even when battery is less than 100%. If it is 100%, I can get up to 1.5 hours or so.
4. Whenether it stops charging - I notice that the back of Kaiser gets pretty high.
5. Every 40-60 minutes the charging light comes on again and charges for about 10-20 minutes (gives couple % to battery), then comes off again.
6. BatteryStatus app shows:
6.1 When charge light is ON: + some MAh, don't remember exact number, but it's like 10 or 20.. very low charge
6.2 When charge light is OFF: full battery drain, -400 or somewhere around there (can't remember). It seems that power flow through USB port just stops, disconnects.
7. I see same results when using car charger and stock AC power adapter.
8. Traffic definitelly affects it. If I just have HSDPA on and not using it - it charges fine, it seems. When I start using up the traffic (download files, watch TV, etc) it starts to heat up and stops charging after some time.
It seems to me that the problem with Kaiser stopping to charge when using HSDPA is caused by heat. There must be something on the hardware that turns off charging if the processor/MB/hardware is overheating. I guess charging the battery generates more heat than using the battery, or why else would it turn off charging when overheating?
Just thought that this, perhaps, would be interesting to some developers or people who have the same problem. Maybe someone can put Kaiser in front of a good fan and see what kind of result does that give - maybe it will keep charging.
Assuming that this is true, I don't suppose a fix is possible. Except for, perhaps, switching to slower connection (not applicable in my case) or putting kaiser on a bag of ice.

What does the Batterystatus app read in all above situations?
Since I exchanged my Kaiser, I don't feel the unit getting hot anymore. The previous unit used to get v.hot using wi-fi and 3G/HSDPA - Possible fault?

Scary... I experienced this for the first time last night. Was streaming some vid from my tversity server whilst on the mains charger. All of a sudden my Kaiser got extremely hot. I immediately stopped streaming and let it cool.
I don't think it stopped charging though but I guess it makes sense that it would be protected against overheating.
The only thing I can suggest is try charging with .5 amp... not actually sure that it would charge too well at that though, especially if you're giving it a good workout at the same time.

Try without that 1Amp powered USB hub to a laptop....
1Amp is max i gues... so maby it's giving less, so it take a long time to get from 80% to 100% and yep lot off heat....

I don't use it anymore, but before, if I remember correctly, it showed around small charge (+) when light is on.. then, when phone stops charging it used to drop to full battery drain, around -400 MAh or something like that.
So you got a new Kaiser and it doesn't heat up when using HSDPA? Really?! Have you tried using HSDPA for a long time (actually using the traffic like tethering, MobiTV, etc..)

I see exact same problems when connected to a AC power supply that it came with. Same problem when using car charger.. and same problem when powering by USB without the AC adapter.
Here's my theory... Lithium ion batteries have on-board microprocessors to protect the battery and device from damage. If the battery gets hot the processor will shut down the charging to prevent damage. No matter what tweaks you do to the device or modifications to the charger this on board processor will override and shut down charging if it deemed it was necessary.

No, I said the replacement didn't get hot - read uncomfortably hot - It does get warm, but only in the same way it does when taking a long phone call. My first kaiser used to get extremely hot when charging which indicated a short somewhere. All is well now though.
I hope you can get this sorted though - are you able to get a replacement?

Ahh, I see.
Yeah I think I'd be able to... but mine doesn't get "extremely hot".. it's just.. warm to very warm. It seems normal for me, don't think it's heating anymore than it should.
Have anyone had this problem with 3G (not hsdpa)? Cuz if it happens in 3G as well - that means another reason to be pissed at HTC - they've design kaiser in such a way that you cannot charge and use HSDPA at the same time.
This problem can be easily recreated and a result from other user would tell if it some device or not.
HSPDA with streaming music while charging = warm
HSPDA with streaming video while charging device = Extremely hot
At this point the USB charging will shut off for whatever reason. I just wondering why the phone is putting out that much heat and can it cause problems since I am starting to stream video via HSPDA while charging a lot.

Maybe we finally figured out why they included the option to disable charging when connected to a PC..

I was just thinking that on some systems it might have interfered with craptive sync. I never guessed that it was because of direct charging issues.
Do you still have problems if you are plugged into the OEM charger, and not a USB port or hub?

Yep. I tried tethering through WiFi (successfully), and same result. Maybe even heats up more, since now there's one more module to power up.
Somebody told me some time ago that iPod charger fixes these problems... can anybody confirm that?

My Kaiser would get hot with a teathered WiFi data connection, but I don't think it ever stopped charging on me.

Hmm.. sorry, but, are you sure? Try tetheting through a powered USB and.. I dunno.. do a big download or something, play an online game.. do something traffic intensive.. it should stop charging.. if it won't - hell, please let me know!

i have an att tilt with the stock rom minus the bloatware.
when i installed battery status (basic version) i noticed that my charging became extremely slow. with the ac charger after the battery status install...it registered +350ma, then it fell to +110ma and wouldn't go any higher, no matter if i soft-reset or not...sometimes it was simply 0. i tried usb connection, ac connection, it didn't make a difference. the charging crawled along slower than i had ever seen it. 39%...40%..........41%. i had enough and i deleted battery status and softreset.
when i rebooted the phone, the battery immediately read 100% (from 41% before the reboot)!!!! and the charging was back to normal.
so my suggestion is to see if removing battery status...and see if that helps?

That's really bizzare.. I had BS for a long time and never seen any problems, actually.. I just reflashed and haven't installed BS on it (I have no need for it now). We'll see if it makes any difference.. I hope it does.

I never got teathering to work through USB. I'd either teather through WiFi or BT with the a/c charger plugged in. I'd imagine teathering through WiFi would be the worst. Most times I teather I'm just reading email, visiting various forums, and on rare occasions I'm downloading music. I'll have to try later and see what happens while I download music over a teathered WiFi connection...

My Kaiser was absolutely baking last night.
I have a stuck pixel so was using a video that I found somewhere that you play on a continuous loop. The phone wasn't completely flat when I started playing the video but within half an hour or so the low batt notification popped up so I stuck it on charge (supplied mains charger).
I was connected to wifi but wasn't actually doing anything with it (video being played from sd card), in fact I wasn't even using the phone, it was just sat on the side charging and playing the video.
About an hour later I came back to the phone to find it was extremely hot. So hot the heat had travelled right through the phone body and even the screen was hot to touch and the battery was still flat so had clearly stopped charging.
I immediately switched the phone off and removed the battery, even then it took an age to cool down.
I don't know whether to get on to Orange for a replacement... I don't think it's right that it should get that hot.
This has been discussed before but some nice new information is coming out in this thread that ties a few things together.
The Lithium battery does have an onboard charging management system that will stop charge if the battery overheats but also if this heat is combined with high current drain. This should be at a precise point but I have experimented with three types of battery and get very different results between the three AND also between batteries of the same type.
The best performing battery seems to be the latest Samsung (P/N 35H00086-00M) with the external 'X' shaped heat spreader on the back that connects to the four earthing points in the battery compartment. Ealier batteries and some 3rd party batteries have this earthing spreader covered with potting compound or even omitted.
One other item I have found, a 1A rated USB port does not give a continous 1A output. Most ports are only rated at 1A surge and will only give out approx 600mA continuous before IT'S own thermal management system cuts off and kills the USB completely, this is probably the cause of comms loss by some people.
Nice informative thread DarkDvr.
Hi,
I have a new and flawless Note, the USB connector is OK.
At night I connect the Note to the charger and I put some music on to fall asleep. Playback is configured to just play one album once.
Normally I put the phone in Flight Mode, in order to sleep without unnecessary radiation next to me.
On some few occations (it happend to me for like 5 times now), in the morning, the phone is not charged at all! But I am 100% sure that the battery status icon on the top bar signaled the charging mode.
This morning it happend again and I noticed that I left the Flight Mode off (because my wife is away and I want to stay in contact if needed).
Also, I noticed that I have been using a ZTE charger specked with 750mA, while the original Samsung Galaxy Note charger is rated 1000mA.
Can it be, that I was using the ZTE charger on its limit and that having apps running, or maintaining flight mode off, was enough to actually not being able to deliver that extra juice to charge the battery?
The other reason could perhaps be a software problem, like some app draining the battery as much as the charger is able to charge, so in the end the battery stays more or less the same.
I am positive that the USB port is not broken. I.E. I tested by unplugging and plugging the charger from the wall socket instead from the phone and all is recognized OK. Also, no issues when connecting to the PC.
What is odd: on previous occations I think I remember that I just plugged the phone back and it charged.
I swapped the chargers, but still I have this odd impression, fearing that the device might have an issue.
Anyone had similar problems?
Cheers,
vma
Yes, looks like a weak USB charge problem. You get similar behaviour if you try to charge the device from a PC - sometimes I have mine plugged in to my PC at work all day and it barely charges. Get home, put the official charger from Samsung in from a walk socket and it charges in an hour or two max.

So my HTC One does something really weird sometimes and im afraid if this keeps going on something bad will happen to it.
since i got 5 months ago this has happened like 4-5 times. and i charge it every night. so, sometimes when I charge it and go to bed I wake up and check the phone and even though it was charging when I left it it has only charged for like 20% and even though its connnected to the charger the charging icon wont show. plus the phone is too hot. and i dont mean warm or hot on the back. I mean too hot to touch everywhere, not only the back. Everywhere it has aluminium its too hot. this has only happened 4-5 times and I immediately take it off the charger wait a bit to cool off and then start charging it again and everything is fine. While its hot no warnings pop up and the phone works just fine, but its extremely hot and even though its connected to the charger it doesnt charge. why is that?

Hey,
This might be a problem with the charger.
Try using the original charging set provided with the phone.
Is there anything you do with the phone that may be considered out of the normal when you charge it?
Worst-case scenario, this might be a hardware fault. In that case you should be able to claim it under warranty.
Good Luck
Something similar happens to me on occasion. It'll be plugged in but when viewing in/out mah, it actually shows it's draining. Less than when it was unplugged, but still draining although it says ac plugged in. (using battery monitor to view btw). When it does that, and it's left plugged in (like overnight), it's abnormally hot when I check it. I have to unplug it and then plug it back in (sometimes a few times) before charging levels go back to norm.

It happened on me for 1 or 2 times as well, the only different is mine is not really hot. After i flashed custom rom, it seems everything is fine. I guess maybe there are some bugs in the original rom. Now i am using the rom based on google edition. Good luck
I am using the original charger and it does this but it also have done this with a samsung charger i have used some times. something else that I noticed is that when I'm charging and using the phone sometimes the battery percentage drops.
Hello. My Note 5 started to show this weird issue while charging thru cable (please see linked video), sometimes it stop acting up and "cable charging" shows but charges super slow (like 5 hours or so to full charge) "fast charging" doesn't kick in either. Charger adapter and cable are good because I tried using it with my mom's S7 and it works great, fast charging and everything so it might not be the adapter nor the cable. Also, sometimes the battery says (for example) like 20% and suddenly drops to 15% and if i reboot, it boots with a different percentage (sometimes more, sometimes less) also, I should add that it charges fine thru wireless charging. anyone experienced this issue or something similar? Any help will be appreciated!
This is the video showing the issue, the video is not mine but it shows the issue I am having, mine is not as bad as the one on the video, but nonetheless is the same issue
I should add that I already tried formating the device and also tried Odin with the latest PH2 update and still does the acting ?
Hi,
My wife's S5 mini seems to have developed a nasty habit of not even fully charging overnight.
When using a USB powermeter, I see the current fluctuating between (roughly) 200 and 800mA. Other devices on the same multiport USB charger have no such issues, so it is not the charger.
When using the OEM charger and lead it will also charge very slow, to the point where it may not even be full the next morning.
I downloaded the Galaxy charging app (very informative on my S4), but it always shows 1mA chargingcurrent, so I assume it does not work on the S5 mini.
I cleaned the USB-port on the phone and removed some lint, but no difference.
Wiggling the micro-USB-plug makes no difference, nor do different charging cables.
We switched the phone OFF and removed and reseated the battery: the problem persists.
What I did NOT yet do is swap the battery (we have two same-age S5 mini's in the house and only one has the issue). If I can pry the second one from my daughters hands, I will try this and report back. Obviously if the problem moves with the battery, it is the battery. If not, it's the phone. Or if the problem is gone, then it is just those darn Gremlins again.
What I also did not do is boot into safe mode (or whatever is sometimes adviced) as the phone does not go through its battery fasst, it just charges very slow. An inefficient app would also not explain the fluctuating currentdraw (certainly not it dropping below 500mA when battery is 80% empty), so atm I don't consider an app to be a likely culprit.
Any ideas are welcomed.
Ideas:
1. Install and use the free app Ampere to check both cable and charger;
2. Turn phone off and plug in charger, even off it shows the percent charged, so you can check if it's system software problem or not.
Check if the micro usb port is dirty. You can't imagine how much dirt can get there, specially fibers from clothes. Normally I use a needle to clean it, maybe there is something more appropiate.
Got the same problem after 3months use.
To avoid this problem:
1- Plug the charger
2- After 5 seconds connect micro-usb into the phone
If you connect first the phone to the charger it will not charge properly
