Hi got a problem with charging.
When I run VideoReg program (video recording program for use in car) and Igo Primo simultaniosly and connect to charger the phone charges for 10-20 min, then it starts recharging. According the batt stats from Android the cable is conected and charging is going all the time, but battery % are going up only first 10-20 minutes and then begin to go down till zero. Then the phone shuts down. The phone during the run of both programs becomes quite warm (not though really hot). The chargers I use are original car HTC (with 1A output) and other original wall charger from motorola (with 0,85A current output).
What it could be? Not powerfull enough chargers or some overheating security kicking on the phone?

I seem to get a longer battery life (first step down from 100%) if I charge my MDA C4 using the supplied charger as opposed to a charge from a PC using the USB lead.
If I charge using the charger, and just use 2G, I get approx 14 hours before the first drop in the batterymeter. From the PC it happens well before 11 hours.
Is this possible or am I just imagining things?

To get full capacity phone needs 5v 1000mA (= 1A) input, which is the charger outputs. If the PC USB output cannot pump that amount it might last shorter....
a PC's standard USB port only outputs 500mA (0.5A)
i think the supplied charger may be 2A (cant check atm), i know the official HTC Car Charger is 2A.

My original HTC charger (Model: TC P300) outputs 5v 1A
Interesting. I'll check the HTC charger when I get home.
However, Would this not mean that it would just take longer to charge the battery?
(Analagous to having to fill a bucket of water from a 1/2" bore pipe as opposed to a 1" bore pipe).

My original HTC charger is at 5V 2A.
What I did notice is that charging form USB takes much longer than charging off the wall.

It will do, should not effect the overall charge (as long as it is left long enough!)

Correct, actually water analogy is quite often used here
yes i thought that...
phone charge lasted longer with the mains charger than the usb on pc
and usb pc takes ages to charge full
So I guess we'll all be using our wall chargers now? As the charge is faster and some believe better!
Make no sense to me as to why the charge of the PCs USB cable is not as good as from the wall....
However the slow charge time bit of it makes sense
Car Charger
I have huge problem with my car charger. I use Noname USB car charger, that worked perfectly with my Trinity. Now, when i connect my Diamond it sometimes connects and disconnects the device to USB twice in two seconds and so if the battery is low message about battery fklashes in an out. SOmetimes it does not happen and the battery is charging normally. When i start IGO8 while battery is full and Diamond being charged, it sometimes LOOSES power and after couple of hours it gets out of power even when charged. Sometimes it doesnt happen and the device is charging properly, but very very slowly. When i turn device off, it charges normally. I tried two different chargers and get the same results. But none was HTC original.
It's irrelevent how the phone was charged. If the battery is full, then its full ,and it will last the same period of time irrespective of how it was charged.
Charging rates will vary depending on input current, but once the touch sensor light stays on, then the battery is full.
Is this normal? I don't remember my phone heating up while it was on the charger though I haven't had my phone for too long now.
I had the mini USB replaced when I accidentally stabbed my stylus into mini-USB port
it's possible that you left a data connection or gps going. Also it should warm up a little .
My tilt often has the same issue w/ heating up while charging. When it happens, the charge rate is very slow. It'll occur w/ or w/o the GPS or WiFi on. I don't remember it ever happening when charging on the stock AC charger, but if I charge with the auto charger (12V cigarette lighter) kit, or another AC charger with the same 5VDC output, but a higher current capacity, it'll happen often.
To clear the trouble, I unplug the charger, do a reset (don't jab your USB again!), and plug it back in after it's finished rebooting. Usually that clears my trouble.
Within the last few days I've notice that my phone is charging at unbelievable slow rate via the wall charge that was supplied. I usually get a full charge in maybe 1-2 hr depending on what percentage the battery is at. Once it is fully charge it hold the charge, but when it drains then it would take like 6 hrs to do a full charge. I've tried to soft reset it to see if the percentage goes up, but it stay the same. I turn off the phone to let it charge, but it still charge at a slow rate. I'm wondering is it time to purchase a new battery.
What do you think? And is there any other test I can do?
The slow charge could be one of a few things... One could be the battery as you suspect (and probally most likely).. Also, are you chargign the phone in a diffrent place? If the battery gets too warm from lack of circulation, it will not charge (or just charge much mroe slowly).. It also could be that your USB port is starting to go... IF you have a stand alogn abattery charger available for it (like one on a docking station) try to charge it on there and see if it still charges as slowly.. Another though could be if you are charging it in your car while using GPS or Wifi.. IF those are left on, they suck down the battery a lot faster and thus it uses the electricity as fast as it can pull it in.. I woudl suggest powering the phone down while charging.. that could also help...
i always charge it in the same spot since i got the phone. i dont have a dock charger. its weird last night i was at 49 and i turn off the phone completely and plug it in. woke up today the orange light indicating that it was charging still was on. turn on the phone and it was at 55 percent. WTF!!!!!!!!!!
I guess that touch pro 2 better come out soon.

i have the same problem. Its either your USB port or the charger, so simply go buy a new charger and if it still does it the port is bad....if not, problem solved
or put it in your computer to charge, that avoids buying a new charger.
usb charging is always slower then wallplug charging as usb can only provide
5v * 0.5Amps == 2.5Watt
where
wall charger can provide as much watt
as the charger is made to
but of cause the pda will only draw as much
amps as it was made to support
Is there any difference between (USB) charging from computer (Laptop) and charging directly from AC adapter (Samsung provided)?
Because, I was using my phone more than two month with SetCPU for more batter life, and I was able to use 3 or 4 days. But just yesterday I charged from my laptop and was full 100%. But after 21 hours I got 15% battery renaming. It’s seems like drain battery after i charged from Laptop. Anyway I will try to charge today from AC adapter which is Samsung provided with phone.
May I know if any one experienced this.

The only visible difference should be in charging time - AC adapter should do it much faster providing the current of up to 1A (1000mA), much less then that to be expected from PC USB port.
I'd rather search for some rogue app draining the battery, maybe betterbatterystats would be a good place to start.
there wont be any dfference, the battery will get a charge from either but usb as mentioned wil ltake longer to charge
if i got 21hrs from my battery i would not be asking ANY questions!!..

USB ports are low power
your wall plug has a higher output than your computer USB port
PC USB = 5v 0.5amps
wall plug = 5v 1amp
so a wall plug will charger faster.
use SetCPU governor, I am sure you will get 3 to 4 days (moderate usage). same as mine.
My final finding; If we charge through PC-USB, it will take time to charge and same time, will discharge rapidly. because I charge my phone yesterday with AC-adapter and now my batter level is 13 hours with 95%. While I charge from PC-USB it was 20 hours with 15%. (all time are in moderated usage, and no any apps are not installed during this period)
I don't know how this, but this is my experiences.
I get the same results that's why I don't charge it through my usb port.
I agree with your conclusion that low-power charging just doesn't last on the Note. I was travelling and mistakenly took the wall adapter for my Plantronics BT headset instead of the Sammy adapter. It charges basically at the same rate as the computer usb. It took forever to charge, which was expected, but drained EXTREMELY quickly (10% / hour with almost no usage). By the end of the trip I was keeping it plugged into the charger whenever possible.
Back home on my original charger the phone is behaving like normal again. (84% after 8 hours with BT on and about 20 minutes of talk time / display on)
Hey guys,
I haven't used my Galaxy Tab S2 in a while now. When I plugged it in it was at 0%. I used "a" (possibly not original that came with box) OEM 2.0A Samsung Charger + Note 5/Samsung Official Cable to charge my tablet. It has only gone up by 5% in the past 30 minutes.
Also when it was at 0% it said it'd take 7hr 12min to fully charge.
Is this normal when the tablet has not been used in a long time, or am I possibly looking at a bad charger/cable as the charger and cable charge my Note 5 just fine at the normal (non-fast charge) speed where it charges my phone fully in just over 1hr 30 min.
If someone could help me out to resolve this I'd be grateful.
Thanks! :laugh:
Don't think the charger and cable are faulty as they work on your mobile. Generally whenever I charge my Samsung galaxy tab s2 using a different charger it shows a notification if the charger plugged in is slow. If it didn't show this I don't see why it would take so long other than the charger your using has a lower output causing it to take a lot longer than usual to charge.
Every android device I have will sometimes not charge fast enough - it doesn't matter what charger I'm using. If I catch that the charge is slow I just unplug it and replug it a it'll be normal again. I think the "smart charge" goes crazy sometimes.
I had the same problem on the tab s2 8''. It was because the motherboard broke. They fixed it under warranty.
When I had this problem I couldn't attach any external device (usb, playstation controller) through USB. Try if you can
I don't have the original charger anymore to compare on my 9.7. I use anker potable batteries to be free of wall sockets. It isn't 2.0. In battery monitor widget, really good app, shows charge anywhere from 1200-1600mA 20% per hour while in use during charging. 5 hours total. I think with screen off I get 30%. I get 10 hours of screen on time zero loss with it off over night. Using 5.1
It could be the motherboard. I know with laptops charging starts to mess up a few weeks before it no longer works at. The connection between the USB and board weakens over time/use.

Sounds normal. The big Lion batteries in these devices are just weird at time. Running one down to 0 is a good way to kill the battery permanently. Let it charge slowly and then keep it above 20-30% from now on. Should improve over time.
I think its a myth you shouldn't let the battery get low. As long as the battery itself says I'm at zero at the correct voltage then zero is perfectly fine. I'm not an expert here but at 5% battery I'm at 3.6v and will turn off in a few minutes after that. I think batteries are manufactured to safely go down to 3.2 before saying no more. Need to charge.
