Adaptive Fast Charging Causing Fast Drain - T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting

So this makes little sense to me, but I have found that using the charging block from my note 3 (not adaptive fast charging) gives me way better battery life than if using the note 4's block with fast charging enabled.
My phone lasts about 7 hours after charging to 100% with the N4 charger but well over 16 hours after charging to 100% with the n3 charger.
Anyone else getting this phenomena?

Wow! I don't have an old charger but will test non fast charge and see what I get.

do you get the same results when using the stock charger but disabling fast charging in settings?

Still testing. Only been awake a few hours and just recently unplugged

I use a mix of wireless, fast charging, car fast charging, and a Motorola wall charger. Have not noticed any difference. I change batteries to new ones at 6 months as well. Maybe a battery going bad?

Charging time and use

Hi,
How long does it usually take u guys to recharge ur note from dead or almost?
It took mine. Over 8 hours to charge from 12%.
Also if keep my note on charge but im usimg it for browsing or whatever, my note still dischares.
Is this normal for the note as my htc Desire didnt diacharge while using it while connected to the charger.
Thanks
Neil

Hmmm I've never really timed it but its gotta be around 4hrs for a full charge.
I have been playing Stardom even when charging and it gains battery.
That doesn't sound normal at all.
If u r charging from USB port den its possible. Charging from ac will be a different story
Sent from my GT-N7000 using XDA
Charging by USB is at around 12% per hour, so it does take 8 hours.
Charging by a/c is upwards of 35%/hr.
Some of the apps usage would demand battery usage at 20-25% per hour, so if your battery usage is more than your charging rate then you would be losing battery which is what might have happened when you are using USB charging etc.
If your stats are for a/c charging, then I suspect the charger.
Yeah i charged for 8 hours with ac and also got discharge while using the note and charging.

Depends on what you are using for, but it still doesn't sound right.
Mine charges from 5% to full in about 3 hours when it's just sitting
on the table and I'm just using it for a phone call every now and then.
charging shouldn't take more than 4 hours when done from an AC outlet. just check if you have original batteries and charger. if not, take it to the shop and get it replaced immediately. 8 hours is just too much.

Im using the stock charger.
Rocket rom / Abyss 4.2 kernel
And battery life was around 20% after around 14 hours then i put it on charge and used it for about an hour but it discharged to 12%.
I am using the device heavily at the moment as ive had it only a few day.

When you are using it heavily while charging it might be normal,
try leaving it alone while charging for one cycle, that'll give you
an indication.
If it's still substantially higher than 3 to 4 hours under these circumstances
you've got a problem, either battery or charger have an issue, or there's an
app sucking battery like hell.
as said, 3-4 hours is normal. Do you have a battery drain issue when in normal use? if yes, then u can use betterbatterystats to check which process is using the juice.
Also, its advisable (in the first cycle after flashing a rom) to charge the phone with switched off. After full charge, take out the battery, wait for 1 min , reinsert & restart. This will help to reset the battery & start afresh.
From 8% to 100% with the charger it took me less than 3 hours.
I only charge by USB on my PC and its never taken close to 8 hrs for a full charge..
The only time charging has taken a very long time for me is when I ran a ICS ROM.
So i did a charge with my usb cable and it tool half the time. Maybw theres a problemwith my ac charger.

How long does it take to fully charge your Z1

as the title says,
How long does it take to fully charge your Z1 from 0%?
mine takes 2.5 - 3 hours, I do think that this is quite a lot although it is faster than my old xperia S which took ~2 hours with almost half the battery size. But I was expecting more improvement from the promised 70% with quick charge 2.0. This is around ~40% improvement, or am I missing something?
From 5% left charge to full. Three hours

I don't think Quick Charge 2.0 adapters are out till early 2014. Even if they are, the one that came with my Z1 doesn't support it. Only Quick Charge 1. You can tell because the output is listed on the adapter (mine is 1500 mA).
Quick Charge 1 works on .7 to 2.5 A. Quick Charge 2 is 4+ A. (Standard USB 2.0 port will provide 500 mA while USB 3.0 will provide 900 mA).
So my 1.5 Amp Z1 charger isn't even at the top end of Quick Charge 1. With that said, I haven't tested a full charge. But if plugged into a USB 2.0 port, it barely charges while phone is on (few percent an hour maybe).

what you said does really make sense because quick charge 1.0 promise ~40% faster charge which I reported in my first post (+1 for that). Now is there any way to check whether the Z1 support quick charge 2.0? I know the chip S800 does, but what about the battery software or other internals (I am not really expert in this area). if it does then when new adapters are released with output more than 1500mA we will get faster charge time. I have my nexus 7 charger which says 2000mA, would this make difference and would it hurt the Z1 battery if I used it?
One last thing, if the output is 3000mA does that mean half the charging time? or there are other things to take into account?

All Snapdragon 800 chips have the QC2.0 circuit so we're good. Just have to wait for chargers.
I'm not an electrical engineer (studied mechanical) so I can't comment on things like losses within the charging process and all that technical stuff. However you have the concept right and in general that should be true. 3A charging a phone should charge it twice as fast as 1.5A

I've just made one test from 6% to 100% it take more than 2 hours i don't know if it was with qcharge 2 i've used the dk31 with a old AC to usb.
Other charge are made from 30-40% to 100%.
Mine takes an average of 2/3 hours to charge from 5% to 100%, I do however only use 1 Amp charges which are old phone chargers. I think I shall get my Note 2 plug out which is a 2 Amp charger and see how that gets on, I totally forgot I had it and I kinda annoyed me with its hissing noise...Even though I found out later it's normal!

The iPhone 5 has a battery half the size of this... I personally take about 2 -3 hours to fully charge the phone using the Sony provided charger!
Started Charging at 1:06 am - Battery was fully discharged.
1:23am Put Phone on - Battery at 11%
2:31am Put screen on - Battery at 52%
3:06am : Put screen on - battery at 73%
4:19am Put screen on - battery at 99%
4:26am Put screen on - Battery fully Charged .
I think the problem with the provided charger where the output is only 1500mA. the SGS4 with sd600 (does not support quick charge 2.0) comes with charger with output 2000mA which I tried with my Z1 and slightly improved the charging time. what we discussed earlier about early 2014 release of the quick charge 2.0 compatible chargers is the solution, I found couple of sources that confirm this. so we hope that better chargers to be released soon with 3000mA + ouput which would reduce the charging to to less than half.
it took 1 hour 40 min to go from 20% to 100%, I'm using the charging dock that came with the phone.

mine is taking too long: after 3h went from 20% to 50% with original wall charger

Charging time will depend on the activities of your phone like running apps, wifi, gps, data - 2G/3G/4G, Screen brightness, etc.

Mine takes an AGE! Sometimes, while plugged in, I get a message that it's draining faster than its charging...
Why is this happening?
My first reaction is that it is a side effect of the larger batteries, but many laptops have larger batteries and this doesn't seem to be an issue...

Ok it seems after a reboot charging time went back to normal with origila wall charger.
What about charging via usb? Is it a looooot slower? Like 20% in 2h

Slow USB charging?

Anyone notice this? It actually loses charge, faster than it can charge. Using same computer ports as when I had my note 3.
Use the wall plug. A computer does not put out enough
NOTE 4
Using any 2 amp charger I find it charges surprisingly fast. Computer ports usually give you only .5 amps. If you were using a USB 3.0 port and cable with the Note 3 you might have been getting much more juice out of the same port.
Yeah, my computer has USB 2.0 and 3.0. Like I mentioned earlier, my note 3 didn't have any issue. Strange.

Gps and navigation software use a lot processing power and the screen stays on all the time, so shouldn't be a surprise that battery goes down fast. In order to keep up with discharging rate you need 2A or more battery charger usb port is not sufficient.

Thanks for the info. I was surprised by this because it never was an issue on my Win mobile phones or iphones. I bought a Qi wireless charger that uses the lighter for power and it seems to be able to keep the phone charged while in use.

Charging time?

Is it just my device or does this thing charge super slow? I can't even get a full charge in a hour and a half and the battery is only 410mah.
Do you use original AC Adapter? I use another one now and I can get it charged in 45 minutes, which is ok to me.

I would advise against doing this. You will shorten the battery life due to the extra heat produced. Always use a lower amp charger unless you are in a rush!

Can someone tell me how long the actual charging time exactly takes ?
I use the original charger that comes with the device and it takes about 3 to 4 hours to fully charge the watch.
I find that quite long as I read the comments here.
The first tames it takes only 1,5 hours to charge it but all the other times it goes real slow.
A factory reset didn't help to resolve this issue.
Thanks.
As far as i remember battery have a capacity 410mAh, original charger have power output 700mAh, so charging time should be about 40-45 minutes max.
Change usb cable, if it doesn't help change charger (but it should have power output >700mAh)
PS. AFAIK using charger with power output >700mAh is harmless because watch limits charging current by itself.
Measuring charging time is best indicator.
Charging with 2.0A adapter will not increase the charging speed - the watchregulates the charging current, it will not just blindy "connect" the charger to the battery (in fact, I can't think of any piece of electronics that would have the charging logic in the adapter nowadays).
I had no problems with any chargers, not even with USB charging - the battery is very small, so unless you have a charger that can't put even 500mA you should have no problem.
I've seen an issue where the watch was "charging" constantly and ended with 85% and wouldn't charge anymore - reboot fixed that and it showed 100%.
I was thinking that your charge takes so long because you could have some process draining your battery in the meanwhile (that starts when you connect your phone, like a tasker thing or smt). Newbie thoughts so correct me if this is impossible
I could try to do a factory reset and see after that if it charges much faster then now.
For the moment i have a few apps on the watch, i do not know if it matters or not for to influence the charging time.
It's weird that we do not have the ability to load the watch while it is off.
From the moment that i put it on the charger it turns on automatically !
hello my friends.
the charging dock is limited to 0.85 A (850mA)
It makes not more sense to use a Adapter with 2.0 A Output. It won't charge faster.
Look if every pin on your dock is ok.
also the connection pin on your watch.
Try to clean a little bit with high percentage alcohol.
best regards
Problem solved by using another USB cable.
Now fully charged in 1,5 till 2 hours.
I haven't measured the charging time of my watch but it looks to me pretty fast. I guess with original charger 30 mins - 45 max, not a min more.
Don't sweat the amps

Hi,
that statement isn't particularly correct. The charging system in the watch (as with any LiIon battery) will draw as much current as is "good for it" and no more.
Just because a charger offers 2A doesn't mean that this is the amount of current flowing through the charger / battery!

To fastcharge or not to fastcharge

Hi!
What is the consensus for fastcharging, is it harmless or is it better to disable for battery health/life in a long run?
Sent from my SM-N910T3 using XDA Free mobile app
Personally I leave fast charge off unless I need to use it. I charge my phone at night while sleeping, so I don't care how long it takes to charge. I don't know for certain, but as I understand it fast charging in general is detrimental to the life of the battery over all, due to higher heat.
Thanks, thats what I am thinhking as well, charge regular if you can afford it (like overnight)

This is purely anecdotal but my S6 battery definitely does not last as long as it did when new, and my usage habits have not changed. I no longer quick charge it unless I really need to. I don't quickcharge my Note 4 either. In fact, I never plug my Note 4 into the wall -- I just rotate 3 batteries.
I leave the fast charging mode checked but i use a regular 2.0amp samsung charger on it and have seen no issues with degrading battery life. The Adaptive Fast Charger (AFC) i use only if I'm out all day (work 12 hour days 2-3 days a week) and i want to top it off. So i only use the AFC a couple times a week. I still get teh same battery life i did when i first got the phone.

Same here.
Adaptive fast charging isn't good for the battery when done in excess, but cells are relatively "cheap" and can be easily replaced (at the same intervals that one would change the internal battery for a normal phone).
Use mine all the time. I never keep a phone long enough to worry about a bad battery. Even if I did, with the removable battery it's no big deal.

I user fast charge all the time. I haven't noticed any battery degradation yet. That being said, if it does start to degrade I can buy a new battery for cheap. I have had this phone since November of 2014.
