Throughout a day I charge my Tilt from a variety of sources: the stock charger, my old Apache's charger, my PC, car charger, my Moto headset charger ...
Looking at them all the only difference I see listed is the amperage.
The Stock charger is 1Amp, so is the Apache's
The Moto charger is 550mA
iGo Charger is 1.5Amp
no idea what the PC or the car charger output is.
I am assuming that the differences in amperage would simply effect how quickly the battery charges to full. Is that correct?
Maybe also that a fully depleted battery would need a full 1Amp charger to begin charging ... the 550mAmp might not cut it for a fully depleted battery.
Would charging with a lower amp charger (550mA) or a higher amp charger (1.5A) have any long term negative impact on the charging or overall battery life?
Just curious ...

The amp rating is the normal maximum current that can flow from the particular charger. They all are spec'd to put out a regulated 5V but the current comes into play if you are using the phone at the same time as charging. If the phone draws more than the charger can supply then it's going to take longer to charge or may not fully charge. Normal charger is 1A and with that the phone can be used most likely at the same time. With a 550ma charger I'd turn the phone off (standby) to ensure a full charge in a reasonable time.
None should affect battery life, just time to reach full. The charge lite on the phone is your guide, when it's amber, it's charging, green it's full, simple as that.
The only thing that will harm the lithium is to take the phone to dead for long periods, that's the hardest thing on a lithium.

Voltage on a tablet power supply is more (2Amp from what I remember)
Can you recharge an SGS with it, can it cause damage?
I think you can charge it because its the micro-usb and the voltage can be high but still i dnt think it will cause a damage but on the safe side you should use the one for the phone
!!!
U can charge it. Compare the voltages on tablet adapter and the original one, if the differense is near 20-30% it OKAY.
Hi, I've been using a note for about a month and a half now, and all has been well.
Until about two weeks ago, when my phone started charging very slowly via USB. Using a 2.1amp charger, it takes about 4-6 hours to charge, and about 7-8 hours using a 1.1amp USB charger. The less said about 0.5 amp chargers the better!
However, when I'm charging using a 1.1amp charger (Standard USB output), often when at 15 or less percent of the battery, if I still use the phone while plugged in, it actually drains power faster than the USB port can provide it! It will often shut itself down and give me a "extreme low battery" screen, meaning I can't turn it back on until it has some charge in it... which can take up to 20 minutes via the same USB port/wall adaptor
Running stock 2.3.6, unrooted.
You could have a faulty or dirty micro-usb port or a faulty battery.

I have the same problem. My Note is new and I don't think the battery is faulty
With stock ICS in comparison to GB, it consumes more juice thus takes longer time recharging.
This is normal, but sad.

Same here
I have the exactly same problem and ended up here, while searching on google if there are othere with similar observations. I can as well comfirm that during playing certain games the phone looses charger faster than it can be recharged.
Beside that my phone overally looses battery much faster than it used to be.
I found out that you can recharge the phone considerably faster when it is completely turned off.
[edit:] The problem started after the update to Android 4.0.
Now I have no way out but to root my SGN running stock ICS that allows me to do more customization.
I am using SetCPU to limit CPU clock at 1200 MHz (from 1400 max). Only certain apps really requiring CPU power, I specifically allow them to run at max MHz.
This helps reducing recharging time a lot...a lot (even much faster than charging when on GB) and allows more time in outdoor uses. And there is no lag.

I've found the total opposite, I find charging in ICS (Stock not a custom as I've not tried one) to be loads faster at charging than in Gingerbread.
What programs do you have constantly running? The more that's running, the more juice it's gonna use and therefore the slower the charging will be.
How long does it take to charge with the phone off?

Same problem with charging as well.I an using ics 4.0.3 cpw version and it draws more than it gets from the usb charger.
I also experienced slow charging before.
What I do is to close all the applications and see if that works.
Same thing happened wid me... Its Kernel fault.. Try changing kernel.. It will help
Noted by the BEAST!!
Look for runaway tasks consuming high CPU and maxing out the CPU clock rate. You can use a CPU monitor like System Panel Lite, and also simply feel the phone at the rear near the camera. If it is hot you have a problem of some process going nuts.
This is a classic problem I've faced on ICS and I've given up with it and gone back to GB. No problems since.

Just to clarify, a standard USB port on a pc/laptop can only provide 500mA not 1.1amp. Not sure where you got this value from. Therefore it will not provide anywhere near the required current, especially if you are actively using the phone. Most cheapo car chargers are also innadequate at 500mA. The standard sumsung wall charger only provides 1000mA.
What 2.1Amp charger are you using? Its not recommended to use more than the standard samsung charger outputs !
You need 1000 mA (1 A) charger for proper recharge even on GB.

1A is the standard Samsung charger.
So is it okay to force the note to use the 1 A ? standard it is set on 700mA
You can adjust the charging control with Voltage Control
I too started having this problem yesterday after updating to a recent version of Visual Voicemail Plus. Even charging from the wall outlet could barely keep up. Turns out the problem was VVMP continually polling NON-STOP for voicemail. Reverted back to older version and problem ceased immediately.
My point....your problem might be software and not hardware. I'm still on rooted and overclocked GB with franco.kernel.

data cable will charge slower via usb port.
I'm using non-data cable to charge via usb port, it's way faster. Only cons is that u won't be able to transfer any data.

I have been using HTC & Samsung wall chargers, Belkin 1A in car. All chargers provide fast recharge. However, the quality & length of USB cables are crucial.

Just to clarify things, the 2.1amp charger is a USB battery pack, and the 1.1 amp charger is a USB wall adaptor. I'm running 2.3.6 GINGERBREAD, unrooted.
There are two charging rates, slow via the USB data cable, and faster via the charger (where the D- and D+ pins of the USB are shorted). If it thinks that you are using a computer USB when you are in fact using a charger, your charging will be at the lower rate.
I had this problem of slow charging and the cause was a dirty connector, get some electronic connection cleaner from an electronics store and spray the USB connection and cables - that fixed my slow charging problem.

I'll give that a try, thanks
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.
I just bought a Nexus 6, and one thing is strange to me.
When charging with the turbo charger and the cable come with phone, phone shows charging and back to not charging state, repeatedly about 3 minutes, finally stop the repeat and keep showing charging state like regular charging.
I never use turbo charge before, so I don't know it's normal or not.
Since Qualcomm's Quick Charge 2.0 (your 'turbo charge') has the ability to charge devices at higher voltages and amperages ([email protected], [email protected], and [email protected]) than normal USB allows, it is probably negotiating between the device and the Quick Charge charger at what voltage/amperage it should start charging at - once it settles on that, it starts normal charging. As the battery gets charged, the charger reduces voltage and amperage. As a side note, the Nexus charger can also be used as a normal USB charger - it only shifts to the higher values when a proper successful negotiation happens between the device and the Quick Charge charger.
