To fastcharge or not to fastcharge - T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting

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.

fast charge is very useful, it saves a lot of time

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.

Phoneboy 6800mah extended battery

Hi guys,
Just wondering whether anyone else has bought this for there note 2?.
My arrived today, £9 99 from phoneboy.co.uk and not a good start! One of the clips on the new back casing had snapped off, so on the right hand top side the case doesnt sit flush with the phone, but no deal I can live with that, just cant be bothered returning it. Lol.
So I changed my phone up to 100% and started the new 6800mah battery first cycle, ive gotta say its lasting the same amount of time as the original samsung battery that comes with the phone. But I'm guessing I need to charge the battery a few good times first before I see any difference in its life. And I just hope there will be!??
Stay tuned, I will keep you all updated.

Update: 1st cycle
Put on charge at 14% due to going to bed. Mainly browsering Internet, listening to music, a few youtube videos. Browsing google play store. Played a few games.
Not really any difference from samsungs offical battery considering its double in power. Hoping thst will change though after a few cycles

If u do not charge it in external charger u will never see a difference. Phone stops charging ANY battery when it gets to a set voltage. Good luck.

I know for a fact they stop charging when the phone "thinks" it has reached capacity. So buy a 1000000 mah battery and charge it in the phone and see no difference.

take the extended life battery, and when first putting in phone, charge for 12 hrs on AC. then discharge down to critical (5%) and charge back up to 100% using minimum 8-10 hr cycles each charge up for first 4 cycles or so. phone will build battery stats and you should see badass life right away.
Mind running some battery benchmark tools?
I purchased an Onite extended battery here and it should be coming in friday. I posted some results of my standard size Onite battery in another thread and had some pleasing results, even though it's still a fresh battery. The 350ma (+-50ma) slow charger that came with my 2 Onite batteries takes about 10 hours to charge one of the batteries (assuming the 3500mah is true), then this means the 6500 mah extended battery will take about 18.5 hours to fully charge through that .35A charger. I don't mind the normal batteries taking long to charge, as it charges a littler longer than I sleep and the slower the better.

[Q] Does the One discharge faster than charge?

After seeing how slow the One charges in Anandtech's review especially because fast charge is disabled, I have to ask this question, does it charge (AC not USB) if you are for example, browsing the web on​ it?
Definitely yes. I've only found one moment where it's discharged while charging.
That was when I was playing music as well as playing Shadowgun Deadzone at the same time. It was still charging more though because when the game was at a menu (i.e. not as much game activity) it would charge as normal.

Well that's great news as web browsing is as heavy as I ever go on my device, never play games.
I've noticed that while charging in the car and using GPS it discharges slightly faster than it charges so possibly on a very long trip you may eventually run out of power especially if you don't start off with a full battery.
With my iPhone 5 the phone would always charge when using it as a GPS and would get to 100% very quickly.

The battery on mine does seem to go down pretty quickly, if you game youre looking at a few charges a day. At least that's how it's been for me.
Maybe my units a bit dodgy
Strange, on my evo shift (old phone if you've never heard of it), the battery will continue to charge even when running intensive activities such as playing 3D games and such
It also depends on the adapter...Battery Monitor Widget by 3c lets you see the input mAh

That's really bad. I haven't had that for years (since my HD2). In the car try a 2amp car charger. May solve that.

How's your battery life?

My battery life is decent, but the charging time is the slowest I've ever seen on any device I've ever owned. I'm not even kidding. Surely it's just a defect on mine right?
Negative. My charge time was ridiculously slow. To the point that while I was charging in my car, if I was doing things along side it, my battery would actually go down. Plugged into wall, it is slow but charges though. Maybe its just US or a small number?
Waiting to get mine still. Did anyone else notice that on Sprint's website it said the One has a 19 hour battery life?

It seemed a little better this afternoon, but I've basically had the device plugged in since this morning(10am)(got it at 55%, and albeit the majority of the time, it was plugged into the vehicle[which hasn't been very good anyways[[my GS3 also loses battery while on charge if doing anything concerning navigation or streaming]]]) and it literally hit 100% about 20 minutes ago. granted I've been using it like a pack mule. and I'm sure you have too.

i heard they packed a li-polymer battery which makes the battery hold its charge longer for the life of the battery when compared to a li-ion battery.. and i dont think htc enabled fast charge like most devices...maybe someone will mod that for us...we need fast charge!!!!!!! still waiting on my ONE

Actually I haven't used it at all. Got it at 2 PM, was at 60%. Dropped my mom off at the airport immediately after, came home and it was 50% at 3:20 PM (which is okay because LTE was on by default and it's super patchy here so I turned it off). Plugged it in and showered, 15 minute shower and I come out and it's 50% still (plugged directly into the wall). Went to work at 5, 55% when I got there. Plugged it in to the computer we have at the front desk and over the course of my 5 hour shift it eventually hit 95% before I had to leave at 10 PM. Un-****ing-acceptable.
yeah, I'd say mine is a little better than that. I left the screen off and didn't use it for like 2 hours and it went from 73% to 91.
I bought a 2.1 amp charger and it hoes from 0 to 100 in 4 hours
Sent from my HTCONE
I don't have my One yet so I can't confirm this personally, but I've read in a few different places that the charging rate is a little slow compared to other phones. My guess is that HTC is trying to maximize the lifespan of the battery since it's non-removable. Quicker charging would generate more heat and might cause it to wear it out faster.
Yes this is the case. Check anandtechs review.
Brian speculates just as you do that it is for longevity.

First day I got 15 hours. That was the usual installing apps and watching YouTube videos and showing my phone off to everyone at work. Will probably be awesome once I don't have such heavy usage.

If I'm not mistaken, the phone has a smart battery or a circuit inside the battery that prevents it from drawing too much current. It is pretty much a standard among smartphones these days. Therefore, even though you use the 2 amp charger, you may not charge faster at all.

My Galaxy S3 definitely charges faster with a 2AMP charger than 500 mA charger.
Do not charge from a computers USB port, they are going to be slow as **** without fast charge.
Just use a 1+ amp charger. Pretty simple people.
Don't put excessive work load on the device while charging in the car either

I've found thats too much for most phones. It all depends on the charger(most car adapters are crappy), I'd assume. I've had the same with Evo, Optimus, GS2, and GS3. If anything is running alongside gps/navi, it destroys the battery

How to Fast Charge N7000

I'm using a newly bought battery and original charger still my phone take 4 hours to charge full I'm using pa rom even on stock it take 4 hours how to fix it?????
Sent from my Galaxy Note using XDA Free mobile app
Ain't that normal? What's the capacity of the battery?
Gesendet von meinem GT-N7000
There's no official fast charge ROM support available for Galaxy Note.
You can increase the charge speed my optimizing your battery performance. Most Samsung phones take 3-4 hrs for charging depending on the phone state.
Make sure you clear all apps before keeping your phone for charging as any running app can eat up the battery. Look up for any suspicious apps which may be eating up battery.
Use CPU spy to make sure that your phone is going imto deep sleep while charging, if not there's a malicious app which is keeping up the phone awake or there's problem with the ROM you're using.
Also check that your phone is not getting heat up while charging, as it could mean a great power loss which could highly affect the charge time.
If nothing works try changing ROM.
Or at the last case if you are a regular ROM chamger then try to clear up battery stats through some app available from play store which requires root.
One more issue which I once encountered was with my charger cable being faulty( although no signs of physical damage) and I changed it with a locally bought cheap cable and miraculously my phone stopped heating and charged faster.
The more you care for your device, the better it gets.
Hope I have helped you.

I checked my 2 Notes, max current it draws is limited by the charging circuit. Seems no kernel can change that value in the Note.
It charges max at 1 Amp, no matter if you attach it to a charger that can deliver like maybe 1000 Amps, the max current is 1 Amp.
That 1 Amp is also until it reaches about 90% ... since Li-Ion is very picky and actually dangerous when overcharging they slow it down.
It's a statement that I hear often in the wrong context : I bought a new battery and it takes very long to charge. Actually that is a sign that the battery has a big capacity. You can only take what you give.
Of course the charger and cable are very important. I would advice everyone to buy one of those usb charger doctors. http://forum.xda-developers.com/showthread.php?t=2451375

[Q] Charge Time

Okay. I apologize if this has been covered *blushface*.
I have recently rooted my note III. I love the functionality but hate the amount of time it now takes to charge. It is taking more than eight hours to get a full charge. I figured out how to manage the charge to avoid multiple charge times within a day. So plainly stated. How do I get a shorter charge time? I would like to wake up with a full charge!
2 to 3 hrs for mine to go from 10% to 100%.
Are you sure your using the supplied power supply? It has 2amp output.
Read the output stats to your charger please!

Then unfortunately u have a substantial problem my friend.
The supplied 2a charger charges at a rate of 2000mah (milliamps per hour).
The N3 battery's capacity is 3200mah.
If u drain 3000mah leaving only 200, it should only take 1 1/2 hours to reload 3000mah
(these are not "exact" numbers, but pretty close).
If it's taking you 8 hours to put 3000 mah into ur N3 batt, you have a problem with something -
8 hrs charge time should supply 16,000 mah (over 5 times the amount needed)
What do your battery stats say?
Does your device stay charged like it used to? Is it possible you set something up to do work while only plugged in and charging?
Tried another 2 amp charger?
Tried another wire?
What programs did you grant root to?
Have you ran a malware scan?
There are a lot of variables here to examine.

Thank you all for the advice. I looked into the battery stats and everything seemed normal.
The battery was performing almost as efficient as with the stock ROM. I wouldn't expect exact performance from a custom ROM OOBE from prior experience. I was not perfectly happy with the DK ROM that i flashed and suspected that the ROM may be the issue. I decided to try the Alliance ROM.
POST Alliance ROM: Battery is charging like normal again. Performance is pretty standard. Problem resolved.
Thanks to everyone for the support.
P.S. Genjo Enterprises Apps are pretty stellar. i live in a rural area with limited data coverage and the internet booster app makes a huge difference!
My note 3 is rooted running the dynamicKat rom and it never takes me more than 2hours at max to fully charge my battery.
Your reply, while making me a little jealous, has neither added anything of substance or value to the topic of resolving my issue. Please troll on another thread topic.
