I herd reports from person experiencing better battery life by using a non htc or factory charger. Some also say it takes much longer to charge but are now easily getting two days or longer life than with stock chargers. I want to narrow it down and compare the results.
I want to know what is the output mA. It is usually located on the charger it self where it states the voltage. The factory charger for the N1 is 980 mA and via usb is 480 mA. So those who are experiencing better battery life as a result of the switch, what is your mA on the charger? Also what brand is it?
I suspect this is right!
Whenever I use the stock charger, battery drops really fast, even if not using the phone much.
I'll be measuring this and put here the results.
Please do. I'm gonna try a bb charger tonight and see if it lasts longer.
I can't imagine this being the case. The battery holds a specific charge. I have a motorola charger, 500mA, and when you charge via computer USB you are getting less too. At no point have i had exceptional battery life.
I've used 2 different mains chargers, a car charger and charged from 2 seperate PC's using 2 seperate µUSB cables, battery life remains roughly the same, as you would expect.
I use my Nokia N97 charger rated 5v 1200 mA and it charges the phone from empty quite fast...sometimes from 20-30% i get to 100% in 2 hours flat...i get about 1-1.5 days and haven't tried the standard HTC charger yet cos I feel Nokia's are better quality...i even use the old Nokia usb cable but don't think usb cables make any difference.
Your Nokia adaptor will charge faster due to the extra 200mA available to the phone (assuming it's able to draw it, but given the faster charge you would assume so).
Electricity is electricity.
The only changes you'll see between sources is how fast it charges the battery.
There are no magic chargers that charge the battery a certain way to "last longer".
Higher current chargers get to the "mostly full" state quicker because they are dumping power into the battery faster. But, the protective electronics on Li-Ion batteries will cut to a "topping charge" state sooner because the charge speed is so high. The topping charge level is the same speed regardless of charger and so switching to it earlier means you spend longer in that state.
A lower current charger will take longer to get to the "mostly full" state, but it will get closer to true 100% before the electronics kick into the topping charge mode.
The other thing to consider is that the indicators on devices often indicate "charged" when the phone reaches the "mostly full" state and so the higher current chargers appear to "finish" faster. But, if you look at the charging status you will still see that it is still taking on a charge. If you wait until that stops then you will be at a true 100%.
So, if you need to get the phone to the "mostly full" state then a higher current charger is better for a quick boost. But, if you want to get the phone to a full charge then the current level of the charger may be mostly a wash due to the fact that it has to spend more time in the topping charge mode. If you are charging overnight then it really doesn't matter which you use.
Now, one thing that Li-Ion batteries do not like at all is heat. When you use a higher current charger then you heat the battery more and its eventual life (i.e. how many months/years it will last) will be impacted more than a lower current charger. So, for overnight charging I'd rather use a lower current charger. But, if you need to dump a lot of charge into the battery quickly then a higher current charger is faster if you aren't worried about getting it to the 100% full state. But, for small batteries like in phones, stay less than the rating of the batter (i.e. no higher than a 1400mA charger for a 1400mAH battery). Below that level there should be no appreciable harm to longevity, but even still - the lower the charge rate the better in the long run.

It is fuzzier than that.
A higher current charger will likely have the device report "I'm charged" with less power in the battery because what it really means is "I'm just doing a topping charge" and that topping charge can still be a good 10% or more of the battery life, especially higher with a stronger charger since the electronics have to be paranoid about over-charging and measuring the current changes that indicate the battery is truly full are harder when the charge rate is higher.
A lower current charger may not trigger the "I'm charged" indicators until it hits 95% full because it is pushing less on the trigger conditions.
If you have a habit of taking the phone off the charger when the indicator first goes green then you may see more battery life on the lower current charger, but it isn't magic - it's just the silly games that battery indicators play to impress the consumers.
Also, if you have a habit of taking it off the charger when it goes green then your battery may never get fully calibrated and so it may only be 70% full when it thinks it is full. But, a lower current charger may get you closer to full more often and thus cause you to reach a calibrated state easier and quicker.
For calibration you should always leave the phone on the charger until well after the light goes green, keeping it on even after the text indicator no longer indicates that any charge is happening (i.e. the lightning bolt is gone) and even then leave it on for a few hours past that anyway. Once calibrated then you have the maximum battery capacity available (modulo the "age" of the battery). It can take several hours to get a phone completely charged if it is poorly calibrated. And sometimes it may even get better with a couple of calibration cycles back to back (but only in extreme cases).

Two chargers used - one is a mains -> usb charger. (i.e allows USB lead to be used via a mains plug)
Output is 5v @ 1A
Other is a plantronics charger.
Output is [email protected] 350mA.
"Mains" based charger gives around a day's worth of charge with standard use.
The Plantronics gives me 2 days worth at standard use.
There is a fairly clear "boost" in battery life from switching between the two chargers.

Well I just finish charing my N1 battery with a universal charger rated @ 200mA. It took over 4hours, I let it stay for 5. With my OEM charger I would get barely a day. So lets see how my battery lasts today.

Great points indeed. I've learning alot and thanks for the links.
Any one actually time how fast their note 4 charges for them? Mine didnt seem to charge any faster than my GS4 the last few days so I finally set a timer, and it charged 50% in just over an hour and a half. Way off what samsung claimed, considering this was supposed to take only 30 minutes...and yes I have fast charging enabled and am using the fast charging adapter.
In 20 minutes charged about 33%. I am happy, cause fast charging working very well. From 25% to 95 % in 60 minutes.

I've done measurements this morning after getting my Note 4 last night.
I agree. I've found little difference between fast charging, and normal at the levels i was measuring.
Perhaps it works faster between 0 and 50%, which seems to be the stats Samsung always quoted. If there is any kind of intelligence circutry going on, it must be varying the amount of ampage being drawn from the charger.
I've found the amps drawn to be VERY low as compared with the S5. Obviously the voltage is the main thing changing with Samsung's "fast Charging" plug.
For example changing from 90% to 100% I found:
USB 2 lead supplied with phone + normal plug = 23mins 31 seconds
USB 2 lead supplied with phone + fast charging plug supplied by Samsung = 23 mins dead.
31 seconds difference is hardly stallar!
Yes you can say it depends on what apps were consuming resource in the background, but it was just standard apps synching etc.
Screen was off the entire time, and nothing processor intensive was actively running.
But I did notice something interesting:
If watts = amps x volts it might explain why the phone isn't charging that fast at the 90% level.
Note 4:
With anker 40w 5-port charge (capable of outpitting 2.4 amps per port, the typical draw was between 300 and 450 ma
With Samsung fast charger it was drawing between 250 and 350ma.
Obviously I'm not counting voltage, which will definitely play a part in the overall wattage. But there has to be some kind of intelligence here controlling it as it's not steady.
S5:
Anker 5-port: 1200ma steady
Fast charger (not compatable of course): 1200ma Steady
Which is also intereting seeing as the max output is 1800ma, so the phone still isnt drawing the max it could do.
Might try draining the Note 4 down even more, and seeing if it does up the draw when the battery is nearing empty
I was very impressed with the charging.
The ultimate test for me was when I was playing a fairly graphics hungry game whilst being connected to the fast charger. It continued to charge the phone up to 100% from 30% in around 40 minutes whilst playing.
I believe the best way to ensure the results are comparable is to make sure the phone is completely powered down and the battery has had a handful of recharge cycles first.
Anyhow, I am impressed with the charging and the battery consumption of my Note 4 to date
.
Impressive. Considering you were using a lot of screen and processing power. Sounds like a wait and see is in order, see how it pans out.
Battery life doesn't seem bad for what I have used, not but much better than I had on the S5. In time I expect things to improve though.
With me fast charging work very well
30 mins then 50% when playing some small game and surfing web
Sent from my SM-N910L using XDA Free mobile app
I went from 21% to 75% in about 40 minutes the other day (was monitoring), but my device was on and I had used it a few times in between that time... fast charging is really meant to be used when your device is OFF - that's where you'll get the most benefit.
Mine works fine. Remember it works while screen is off or phone powered down. Also from 0-50 only. Beyond that and it will use 5v to charge instead of the 9v. That's why Fast Charging will only work with the charger it came with.

Are you still having the same issue?
Im charging my phone for the first time and i dont find the fast charging works well with me. Its been an hour already and my battery is still at 30%. I also turn off my phone to make sure i get the 30mins 50% but no luck. Should fast charging kicks in after several recharge cycle?
Remember, it's called adaptive fast charging so it's charging rate varies depending on variables such as temperature, etc.
I went from 20% to 96% in about 60-90 minutes today. Not too bad.
I don't plan on using fast charging much to test, but it's my first few days with the phone and I've been stress testing it to see how battery life is.
90mins for me from 1% to 100%.
no problem at all. been charging from 0 to 100% at exactly 60mins
Impressed with mine used to have a spare battery but not anymore as the beast can really fast.
Must use included charger and CABLE
I found that for fast charging to work you must use the cable and charger that shipped with the Note 4.
hey and im sorry to dig this thread out again, but wondering if another tried fast charging with third party battery, I bought a ravpower note 4 battery off amazon and charged it with my note 4 adapter and I went from 10% to 50% in about 50 minutes, im sure its not fast enough.
note 4 adaptive fast charging
The phone has a chip and the charger has a chip it is this that allows the phone to charge at 9v only between 0 to 50. It's easy for people to be unimpressed because Samsung typically charge quickly. I tried a LG g3 for a few days and it charged ridiculously slow compared to a Samsung if it is taking an hr and a half to charge your phone halfway I would consider using your warranty for a new device or battery

is this correct?
It will only do fast charging below 50%?
What if it starts at 45% - will it stop when it gets to 50%?
I'm finding that Adaptive Fast Charging (AFC) only works (phone reads "fast charging") when the charge cycle is started while the phone's battery is almost dead. Now, "almost dead" means different things to different people, but my GS6 won't use AFC unless it's really low - I know it won't kick on/in circa 35%, but I don't know the precise level.
Here's some an interesting comment made on the awesome article at the link below:
"You should note though, that CABLES DO MATTER. Every el-cheapo ebay cable isn't supported for quick charging. They usually allow about 700mA to pass through. You need high quality cables that probably came with your smartphone in order for quick charging to work. I have done several tests with my Note 4 with several cables and an adapter that meters the output Amperage."
http://www.androidpolice.com/2015/0...-need-to-know-about-charging-your-smartphone/
Works great for me take about an hour and 40 mins from 4-fully charged.
I lost my charger so i cant help here
Been looking all over eBay & Amazon, but nothing...*sigh*
To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Xiaomi Mi Mix 3 can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!
I have done some testing.
With QC 2.0 (my old Motorola Turbo charge 15) I charge phone from 20% to 90% with rate 65%/hour (1 hour and 10 minutes time)
With QC 3.0 (charger and cable from original Chinese packaging) I charge phone form 30% to 87% with rate 95%/hour (40 minutes)
I think this scenario is common for most users when they need to charge phone in hurry.
Later I will add also charging rate for quick wireless charger included in box and maybe also some QC 4.0+ if I get my hands on some.
In my case, I bought a PD3.0 charger from Aukey and my Mi Mix 3 is charging from 0% to 100% in 1h08 !
In fact after a few research I found that Power Delivery Technology is compatible with Qualcomm Quick Charge because Quick charge is working with Power Delivery and add a few security technology, but power delivery already have some.
Nevermind, I tested it and indeed My PD3.0 charger (max 15V and 3A) with a anker cable wich support up to 5A is working faster than the QC3 charger !
I suppose a QC4.0 should be better, but for now I think PD3.0 is the best solution !
I second @romain1672...I've converted all my chargers to USB-PD since I've divested from non-USB-C devices and my Mi Mix 3 flies with them.
I believe the wireless charging is relatively slow, think one review said three hours for full charge? But that's expected to be honest.
I've heard it said that slow charging is better for battery life, so in effect, wouldn't the wireless charger be better than cabled, if you're not pressed for time?
It took me exactly 1h45 to charge from 17% to 100% with the wireless charger. It's pretty fast for a wireless charger, but the only issue is that it heats lot of more than wired, and i read somewhere that heat isn't good for battery health.
Hi guys, I just bought the Razer Phone charger (it's the only one I could get quickly with Quick Charge 4.0+ in the UK). Not the most scientific of tests, but it went from 30% to 87% in 30 mins. I tested from 30% again today with a Quick Charge 3 charger and in 30 minutes it made it to 80%.
Sorry I didn't run from 0-100%, I can probably test that more easily this weekend if people are interested?
Fast enough that for the first time since owning a smart phone I never have to think about looking for a charge, even when travelling.
Does anyone know of any wireless chargers/charging stands that charge the mix 3 as fast as the included one? I've tried a couple I had with previous phones and they just charge so much slower
This charger is becoming annoying.
I place my phone on the puck by my bed. Sometimes, before falling asleep, I hear the sound indicating charge stopping.
Then, in the morning I find my phone has moved off the puck. And it is not me! The phone slips away if not perfectly aligned centrally on the puck. It is not surprising as the induction forces between the puck and phone will be opposing but the manufacturer should have spotted this and made the puck/phone with more friction between them.

Bro, I use my brothers Samsung Wireless Charger "EP-NG930" from his S8. Google it to see it. I can't post a pic of it since I leave it in the office but underneath it is rated at 9V 1.67A (15W)
I must say it charges pretty much the same, if not, faster than the included one since it has a built-in noiseless fan behind the coils
Since most of us got this phone in last month or so, we obviously want to take most care of it.I was reading online whats the best way to charge the phone, was it to 80% or just go to 100%, so i was wondering how do you guys charge your 6T?
I've always take my battery down pretty low, and then fully charge it with a slow charger. I generally charge my phone at 0.35-0.5 amp. I've always found slow charging my devices I get run time on each charger than I do if I fast charge it. My last two OP devices the Dash charger hasn't even left the box.
I know they say Lithium Ion batteries don't have a memory, but in my experience, they just seem to have less of one than the NiMH batteries did back in the day. To me all batteries work better slow charging them. Even charging my OP6T at 0.5 amp it charges plenty fast enough. It can be charged by the time I leave work, or by the time I get up in the morning.

I was thinking about getting some slow charger but i guess that included Dash charger, which doesnt heat up my 6T nearly at all, wont kill the battery that fast.I'm no expert in this field but i guess heat kills batteries way faster than high current.And since 6T is such an amazing phone, i'm just hoping the battery will last at least 2.5-3 years.
So I know this is old news, but I still encountered a large enough group of people saying that the 45w charger is useful for quick charges at under 60%, and that it could get you an extra 10% on a 15min charge, so I decided to get one for myself. Keep in mind I never discharge my phone under 20% and only charge to 75%. I have my phone record charging wattage, battery temp, and percentage of charge and log it to a file. I made sure my acc magisk module had a temp cutoff of 40C and the cooldown ratio was null.
The highest wattage this charger has ever delivered is 32W. It very rarely exceeds 25W and almost never achieves wattages over 30. My tests were done in a cool room and the battery temperature never exceeded 36C.
I believe the highest charging wattage I have achieved with the stock charger is 23. That makes charging with this enormous 45W charger and its thicker cable a bit of a joke. Seriously this thing is huge, and a waste of money. I paid $30 and Im not happy.
Unless I'm mistaken, the Note 10 only supports 25w fast charging. Note 10+ supports 45w.
If you have the regular Note 10 then frankly I would not risk damaging it with an unsupported charger for such minor gains. I would try to sell it and recoup some of that money.
