[Q] Charging on the Samsung Galaxy S3 - General Questions and Answers

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

Well, the first charge always takes longer. 2nd charge will be faster.
Btw, you shouldn't use other chargers.

Stock charger for extended battery???

Hello, I recently got my 6500mAh extended battery for my N7100 and I found that charging was pretty slow with the charger that comes with it (about eight hours for a full charge) compared with the stock charger that can charge the stock battery within one hour and half. Therefore, after reading the spec of the charger, I discovered that the slow charge was come from the fact that the output amperage of the charger was 800mA (800mAh). Therefore, by some calculation, 6500mAh/800mAh which was equal to eight hours. So, I then looked at the spec of the stock charger and I noticed that the output amperage is a bit higher, 2A (2000mAh). By the same calculation, I can predict that with the stock charger, I only need about three hours to completely charge my extended battery. Does anyone attempted to use a stock charger to charge an extended battery?

[Q] charger problem on galaxy tab s 8.4 (T 705)

recently I've bought a galaxy tab s 8.4 , but take too mach time (about 6 hours) to charging with it's stock charger (5.3 v , 2.0 A) , when i charged with note 4 charger (5 v , 2.0 A) , it charged normal (about 2.5 hours)
now i have two questions :
1. the note 4 charger is suitable for my device ? isn't bad for battery life ?
2.is it possible that the stock charger was fake !!!???
I only have the 10.5 and i dont really know the full charge time as i only ever charge to 80% so as to reduce the cumlative damage to the battery that is cause when you charge to 100%.
A slow charge is better as it produces less heat than a fast charge does, heat is the enemy of battery health.
Your tab s 8.4 has an 4900mah battery, your note 4 has only an 3220mah battery, I dont really know why one charger charges faster than the other.

You should get yourself a "usb power meter" lots on ebay i have a couple that only cost me £3 each delivered they allow you to see how much power your usb devices are charging at in real time, they show my 10.5 charging at approx 2amp with the supplied 5.3v 2amp charger that came with my 10.5
John.
Try exchanging the cables. Sometimes broken cable can be the culprit.
It is the same MHL3 compatible charger, 2 Amps specified, at 5,2V which is approx 10 Watts.
Should take around 2 hours to charge the 18,6 Wh battery.

1) The Note 4 charger is fine. You cannot overcharge because the kernel limits the charging speed.
2) Who knows, but my T705 arrived with a European charger with US adapter and it charges slower than I expected. Definitely slower than my Note 4 charges. I'll try charging the T705 with my Note 4. Never considered doing that.
I used the Tab S charger to charge my Note 4 today.
Using the Galaxy Charging app, I was seeing charge averages upwards of 1500MaH. So it's at least that fast, maybe faster.
The phone charged in about the time I expected it to, compared against the stock Note 4 charger.

I have the same problem...needs about 7 hours to charge..
I know people are in a hurry, but slow charging is better for the battery, as when you charge the battery fast it gets hot and heat is bad for the battery, also try not to charge your battery when it is hot, left it cool down a bit first.
Try to charge overnight when you are sleeping, set an alarm to remind you to plug it in before you go to bed.
Have a read of the link below, it will give you some advice on how to make your battery live as long as possible, If you have lots of money don`t worry about it.

Thanks my friend for the info...

Find a fast charger, any recommended?

Stock from HTC direct (Digital River) works well.
I own the Aukey Quick Charger, which also works pretty well with the M9:

I use the samsung fast charger from the note 4 or s6 and use the motorola brick from the nexus 6. I recommend the nexus 6 brick.
I will receive my techmatte quick car charger and keedox quick wall charger tonight, will let you know

That's the same one I use in my office. Works well.
I use the charger from my old Droid Turbo at home.

I just got one of those too, and it's great. Wish it wasn't so big, but it does the job.
I just picked up a couple of Anker dual-USB wall chargers. They have higher amperage (2.4A) than most standard chargers and on both USB ports simultaneously (many dual-USB chargers lower the output when both ports are in use). Between the better charging times, the dual ports and the build quality, I'm very satisfied.
The Anker charger with Qualcomm Quick Charge tech looks even better, but I don't have any experience with it personally.
Show me the link and experience, thanks!

i have the htc rapid charger 2.0 and the aukey rapid charger (+the 10000mah external battery quick charge)
both work really well. if i knew about the aukey. i woulda originally gone for that first
Quick review of the Keedox Quick charger 2.0:
Well it has the official logo of Qualcomm Quick charger 2.0 printed on it but I kinda find it as slow as the stock charger from hTC :crying:
Tested from 45% to 100%
Till 80% it's amazingly fast with 20% every 10min but once over 80% it's slowing down, from 90% to 100% it's extremely slow like 1% every 5 mins
It took 75 mins to charge these 65% while it's supposed to charge from 10% to 100% in an hour (80%)
So we are pretty far from the advertised +70% faster charger.
Take in consideration that I am using Viperom 2.2 for the time being based on 1.40, these Roms are known to have bugs with charging time, so I am waiting for the upcoming Leedroid based on OTA 1.40 Rom to be sure this charger is crap and give a negative review on Amazon.
I am still waiting for my TechMatte car quick charger, my sis still didn't finish to empty her 2 suitcases, girls...
I don't think it's a matter of cable, I am using the same USB 2.0 cable that I used back with the Quick charger of the S6 on the S6, it was charging the S6 from 20 to 100% in 50 mins.

The Aukey quick charger I have does the same type of throttling thing once it gets around that 85% mark. I haven't paid enough attention to my Droid Turbo charger to see if it does the same thing. I figured it was just a safety feature of the Aukey charger.

So these are quick charger only from 0 to 85% !! The S6 stock charger on S6 was also slowing down at 85% but it wasn't that slow, the results were certainly faster.
Again I can't give a definitive conclusion about the Keedox before I try a stable rom based on the official latest OTA

The slowdown at ~80% full is the expected behavior to be easy on the battery. I find the quick charge most valuable when I am about to leave home and I can use the last remaining minutes to cram some juice into the battery. Main charging happens overnight for me without any need to hurry.
The slowdown >90% is behavior I have seen on every phone I have ever owned. It is a safety feature to avoid overcharging the battery. Overcharged li-ion batteries have been known to explode and catch fire, after all.
It may simply be that HTC is more conservative with its batteries than Samsung is.

Hmm ...
Now this makes sense ... Now I get why my charger works lil slower above 85% ...
Updated Viper Rom to 2.3, the Keedox charged my M9 from 34% to 94% in a matter of 35 mins
Thanks!
It looks like the htc m9 is slow with quick charger 2.0 anyway, gsmarena posted a 2h charging time for 0 to 100%.
So my Keedox is not bad after all

Battery lasts longer after normal recharging than turbo charging

Hi,
I noticed that when I recharge it with a charger that is only 650ma the battery last much longer than with turbo charger that came with the phone.
Even in standby after recharged it takes one hour to consume only 1% but after turbo recharging it takes about 10 min to drop 1%.
Is there anyone experiencing something like that?
Funny it is.... The case is opposite for me... Although I use Transomart QC 2.0 charger. My battery lasts longer when I charge it with quick charger compared to standard 1 Amp chargers.
That´s so weird.
I am preparing a comparison to figure out what's happening.
It happens the same here. I've a Aukey turbo charger and the battery drains faster

There's no way to actually know the charge (in mAh) of a battery without draining the battery. The way that phones estimate the charge is by measuring the voltage of the battery. Quick Charge 2.0 (supported by the Moto X 2014) uses a higher voltage to charge the battery faster. This can make the battery hit max voltage before it is actually fully charged. That is why Quick Charge always advertises how quickly it gets to 80%. To get to full charge (not just when it shows 100%, but when it is actually fully charged) will take about the same time as a standard charger.
Heat and Turbo charge destroys your battery.
if i turbo charge , my phone will suddenly die when it's between 10-20%. W/ regular charging I get sudden death at 6-8%
i use a moto razr 850mah charger and solved the 8% sud power off, took 2 charge cycles from death to 100% leaving it overnight. Now battery works as it should
.
As I've been reading around (can't recall specific scientific data), the faster you charge the battery, the less capacity it can hold. So it makes sense that it lasts longer if you charge it slowly. I don't know how much would be the difference tho.
It is normal in my opinion. Slower charging is also healthier for the battery and usually will last longer
Has anyone ever used a wireless charging pad with the phone. I bought a stick-on one from amazon and it charges fine,,,slower but fine. However, I noticed that it tends to get suck at certain levels and if I take off the wireless charger at say 89 percent,,,it takes less than a min to go to 100 percent charged?
Recomendeed is charge with Motorola original charger of this device, i mean 1150mAh dual port charger
Anyone here with experience of using Motorola's Turbopower 15 wall charger? I'm thinking to buy one, because waiting for 1 hr to charge to 100% is quite annoying.

If I charge my phone with a faster charger will it deplete faster

Hi guys
I bought moto g 3rd gen (2015) and it came with very slow charger (550 ma) it charges my phone in about 4 : 5 hours which is very slow ...
My question is if I charge my phone with a faster charger like my 1.5a Sony charger will that make it deplete faster ?
I watched a reviewer on YouTube say that , he said charging moto g3 with a faster charger made it deplete faster ( down to 3 Hours screen on time from the average 5 hours he was getting)
I just want to know if that is true or not , thanks in advance
I don't think it's true, the maximum drain on my Moto g is 1.1 A that is only when reboots other than that it discharges around 450 to 700 mA and the charger given with device can charge upto 1300 mA which takes around 3 hrs to fully charged.
Using a higher capacity charger is not an issue... the stock charger is garbage, I use a Blackberry Playbook charger rated at 1.8A and it works just fine, it will go from <10% to full in around 2 hours and battery life is not compromised in any way. Many things can vary SOT, but for the most part your charger isn't one of them especially since this device does not support Quick Charge (which can and will kill a battery)
