[Q] Help (about charging)

hi
I m just curious. This Is my first time charging the tab but maaannn its taking forever. I mean forever like 1% every 10mns. That's the slowest charging I ve seen on any device.
So is it supposed to be like that? Always? Just the first time? Or something is wrong with mine?i
EDIT worst case scenario... its stuck at 5% . What to do now?
Are you using the original charger or a PC USB port?
Charging time with the original charger is about 5hrs. More if you are using the device.
If you are charging from a PC USB port then it charges very slow. If you are using the device at the same time then it isn't charging at all.

[Q] Charging Patterns? Is slow charging advantageous?

Hey all,
So, was over at the other half's house today. Before I left I asked her to stick my x10 into charge for a few mins. When I grabbed it on my way out I was surprised to see it was mostly charged, then I remembered she uses the wall charger while I normally USB. I understand the limitations of USB ports in charging, but it got me thinking.
Can charging the pack so quickly be good for the battery. I'm more up on my Ni-Mh cells than Li-ion but I would have thought that ~1hr charge cant be good in the long run? Where possible would it be better to slow charge via USB like I have been doing?
TIA,
Scratch.
personally, I have charged my phone overnight using the wall charger every night for almost 2 years and my battery appears to be fine. No temp spikes, no sudden drain

battery drains
I nearly always charge mo phone overnight in a power socket aswell, only on a rare occasion i find the battery drains mega fast for no apparent reason. I just reboot, recharge and turn it on again... it is weird but that does the trick for me sometimes. no clue what causes the drainage, even tho its idle. got an app killer on aggressive so that should help, but i'm not sure its just the apps that drain battery.

[Q] Charging on the Samsung Galaxy S3

Well I bought the Galaxy S3 on the first day of the UK launch and depleted the battery to 0% then charged with the original 1 Amp charger from 0%. I had noticed that this takes a very very long time, around 8 hours. The battery life after charging however is substantial and very adequate.
On the second charge after depletion once again, I decided to use a Griffin 2.1 Amp charger which I had used to charge the hefty Galaxy note with. The Galaxy S3 charges at a much rapid rate and takes around 2-3 hours to reach 100% from 0%. However I have noticed that the battery life depletes a bit faster, Is this due to my imagination or is a 2.1 Amp charger not suitable for this phone as it was with the tablet-like Galaxy note.
Also note that I tried to charge my HTC one X with the 2.1 Amp charger and it charge very slowly, while the original HTC charger has a much lower ampage than 1 Amp
Hmm I have been using my galaxy s charger 0.5amp and it has been charging pretty slowly but seems to deplete faster.
I have been actively using for 50min on wifi now and 85% left. Which seems a bit quick for me. I will try charging with the standard 1amp tonight and see.
Now fast are you depleting at?
I measure my battery life by checking the screen on time just before the death of the charge which was 5 hours on the original charger, with the quick charger its 4 hours. My Galaxy note has no change in battery life weather you any ampere chargers. Also the general battery percentage seems to run low faster anyway on the galaxy s3 using the fast charger.

I shall try the standard 1 amp charger the next time my phone depletes

Just wondering, since the S2 had a limit of 650mA for charging, does this apply to the S3? You guys make it sound like it charges slow as well...
Galaxy s2 does charge very slow for me aswell. Compared to htc phones the Galaxy s 2 charges painfully slowly. Now I regularly use the 2 amp charger on my galaxy s3 and have seen a huge improvement in charging speeds. It charges at around 2% per minute and still lasts around 4 hours of screen time for a full charge.

I noticed that I can only charge fast using original charger. While charger with shorted usb data + & - (ie. htc 1A charger) will not activate fast charging.
You can verify by going into *#*#4636#*#*, Battery, using ori charger will show AC while HTC charger will show USB
I think samsung made some changes to the microUSB pinout

Thanx for the "shortcode". Where does one find those?
Also from reading about the MHL to HDMI cable from older devices not wotking, it does in fact seem that Samsung have changed the microUSB pinouts (although my Nokia 1.2A charger shows AC in that battery "menu").
Mine charges from about 10% to full in about two and a half hours, using the charger provided in the box.
My s2 came with a 0.7amp charger and took about 2.5 hours. My s3 came with a 1amp charger and takes about the same. Charges to 80% in no time and then slows down for the later part of the charge

A battery isn't like a fuel tank which you simply fill up through the hose until it's full.
Due to physical and chemical reasons, a nearly-full battery takes a lot longer to fill by a certain percent since it simply can't store the energy quickly enough.
Additionally, deep-discharged batteries often start with a slower charging speed (and then cranked up) to keep the battery from dying too soon and/or not being able to reach full capacity.
is the Nokia 1.2A charger ok to use with the samsung G3 as i got one of these spare and would prefer use it if so as the usb is way to short to reach from my desk up and around the back.
but the Nokia 1.2A charger lead is more than long enough
Just to check with all of you, i've been told that it is best not to charge your phone or any other handheld device IF the battery is not at a really low rate, at least not till your device actually prompts you to charge. They were saying that this would cause the battery life to be shortened. But at times, I need to make sure that i have enough battery to last me for a few more hours before i knock off from work, i would just charge the phone (battery at 25-30%) even before it prompts me to. Is it alright to do that often?
2ndly, at times when i stream videos on my phone for many hours, the battery would definitely drain fast and i would need to charge my phone at least 2-3 times a day. Is it alright for me to do that or am i "abusing" it? =X
Appreciate all your advises...Thanks in advance~
so any update on if using the nokia charger is ok with it being 200mah more than the standard 1A charger since it has longer lead.
or there is the 700mah samsung charger from my old S2

I don't know why this misconception still lives on; lithium ion batteries require no priming on first use. The WORST thing you can do with a li-ion battery is to fully deplete it before recharging. It is much better to top it off whenever possible; having said that leaving it turned on, on the charger once it is full is also not the best thing (though nowhere near as bad as depleting it fully).
I believe since this phone has a removable battery with external charger the best thing you can do is always charge your battery in the external charger and just switch out the battery when it gets to around 10%.
Nek0onna you should charge your phone whenever it's not full and you have a handy charger.

what about using different chargers though as i have said yet not answered yet,
i got a samsung s2 700mah charger and a nokia 1200mah charger which will work the best for the battery etc
the 1A included one the usb lead is to short for use behind a desk

Can anybody check what the max charge rate is on this device with a battery monitor app? I have handfuls of 1A and a couple 2.1A chargers. I'd really like to charge at twice the rate if possible but not all devices support such rapid charging (kernel limits and such). Just curious before I buy one Thanks!
Even if Samsung slipped up and allowed a 2A charge i'd never want to try it, because tablet and laptop batteries are rated and manufactured for a higher current charge/discharge and most phone batteries would heat and swell up and possibly explode.
my HP touchpad charges with a 1A charger and it would be nice to use that with my sgs3.
Can anybody please check what the max charge rate is on this device

Charging Question

does anyone know if its possible to find out if the s3 is really charging or not? ive been plugged in and it's still discharging. I need to know if its hardware or software related. when plugged in it has a lightning on the battery and it has red led when display is off but its really slow on charging

The battery does not charge to 100 %, this is not a defect in the phone but rather a sort of internal protection so as to not damage the battery. Indeed, it happens many times to leave the phone connected to the charger much more time necezzario.
The battery by doing so you may receive a surplus of energy than necessary, and in the long run, deteriorate more quickly. Samsung has inserted inside the Galaxy S3 a limiter that operates in the following way: while the phone is charging, you download slightly of 2-3% for then recharge automatically up to 100 %. This process is repeated automatically from your phone until it is removed from the charger.

While plugged in go to settings/battery and see if it is ac charging or usb charging....I've had this problem with the new cable and plug, it only charges at usb rate, use my old S1 charger now, BlackBerry one worked for me as well

Hmm, im not talking about when it charges at 100 % im talking about when it charges in mid ranges like 50 or 80. It shows charging but an hour passed but it didnt even increase to 2 percent
Are you on an original rom or a custom / leaked one?
Have you tried another charger or computer?
It may take some time to charge on slower chargers (the ones only outputting 0.5Amp) but it definitively should not be discharging when connected to a charger with the screen off.
Im on stock firmware. Using the wall outlet ti charge the phone

Phone Charging

Okay.. well my battery was never the greatest. I mean it lasted a good amount of time when I was not doing anything on it. While using it, it didn't die too too quickly. It charged just fine. Didn't take too long to charge up....
Well now.. when I plug the charger in, the symbol comes up to show it is charging. But it takes forever now to charge. If it's at like 75% it takes hours for it to charge to 100%. Never used to do that. & when I have it charging and I'm doing stuff on my phone... the battery percentage goes down... very slowly.. but it goes down.
So I dunno if it's the battery or the charger. Cuz the charger does work just extremely slow now and doesn't seem to charge up while plugged in & being used. If I keep it plugged in and do nothing on it. It charges... just extremely slow now.
Anyone else have an issue like this?? What Do You Guys Think It May be??
Please help.. thank u

stock charger and cable?
Are you using the stock charger and cable? Have you had to replace either recently? The stock charger will do 1900 mAh with the stock cable. Any other combo I've personally only gotten about 1200 mAh at any given time. Get the app Galaxy Charging Current *lite* and see what you are actually charging at. Could give you an indicator of what is wrong.
