Battery plus symbol question - ZenFone 2 General

While phone is off and charging , a charging battery appears on screen. If I hold power button for a while, + symbol disappears. It's that does plus symbol indicates fast charge? Does it take longer to charge without plus symbol and battery lasts longer?

Yes, plus means fast charge, our phone fast charge 70% after that % it switch to normal charge

Are there any advantages of turning off fast charging mode below 70%?

No and the only way to do that is with a normal charger one that is not Qualcomm quick charge.
The only difference is the heat output when the phone is fast charging but phone has being designed to work normally with this charging temperatures so no no worries about that

Don't worry, Intel processors have always been known for dealing very well with high temperatures, usually better than other manufacturers. And I can assure you this phone heats way less than many other similarly powered smartphones

does custom recovery/ root disable fast charge?
coz i think, fast charge is somehow disabled in my phone after TWRP/Root...
its not fast charging with the same charger with the same cable, which as doing its job pretty good just a day ago, and now its taking so much time to charge the phone...normally it gets charged with one and half hour and now its taking very long time...

Better battery life when phone is charged ON and watching movies etc?

I've been experience that my battery life has improved ALOT when I charge it while it's on, also when I watch a movie or two and then charge it at the same time, when it reaches 100% I easly get more days out of it.
What's your experience?
This makes sense because the Wall charger has plenty of power to quickly charge the unit, while a USB connection is standard at 5 volts.
So the slower the charge, the longer it takes, the better it hold the charge longer.
In your situtation, you are watching movies while charging... which eats most of the power as it comes in, and supplies the battery with a slower charge; thus increasing the battery life until it drains again.
I do this with my Motorola cheap-o phone. If I power it via USB it'll last like 7 days... but if I charge it via a Wall Charger it'll be dead in 2.
Never really gave that any thought. You think the slower cycles going in, then the harder it is to go out? I'll keep mine playing movies while I'm sleeping then to get a better charge if that's true!
I thought that was very bad for the Batery, actually my laptop's batery is already dead (it drains full batery in less than 3 minutes) and I was using your method during all its live, around 1.5 years.
I noticed that if you use the Diamond during charge it warms up very much, compared to when not using it.
I must say that I noticed that some of the cicles where longer than others with similar or less use, I will test in the nexts days and post back.

ALL Devices like phones charge at a nominal 5v. It's the current that is different.
Wen you charge while the the phone is some way in use it works the battery to max efficiency and this results in a more efficient charge pattern.
Charge your phone whenever you can, never turn it off when charging and top up as often as possible. That will maximise battery life and max the potential capacity.
Don't discharge too low either.

Slower Charging Good?

I wanted your input on the better charging habits for our phone, considering the battery can't be easily replaced.
The general consensus is you should keep the phone between 40 and 80% all the time, right?
One thing I've been doing is using a slow charger (350 mAh) to charge my phone overnight. Although this takes much longer (probably 5-6hrs), the battery still gets charged over night but stays between 40-80% for longer. A standard charger takes about 1-2hrs to charge depending on capacity (most are 1 or 2 amp)
What do you think? Am I wasting my time, or is this a good idea?
Yes, you're wasting your time with everything under 1A. It can even wear your battery more than a charger with higher current, especially if the phone isn't switched off, so you're achieving the precise opposite.
The best thing you can do is not charging to 100%, but just to 80%-90%. This could minimize the wear level of tithium batteries. But then again, I wouldn't be too worried about it.
And don't use cheap/no-name chargers, as they can kill you.

How well does adaptive fast charging for you?

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*

Charging speed

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the LG V60 ThinQ can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!
Not the absolute fastest around, but damn sure not the slowest... especially when you consider how much further every 1% of battery will take you on this phone compared to other phones in its class. Fast charging kills batteries anyways, so I charge slowly most of the time since I'm always around a plug these days. I really wish I had this phone back in 2011 when I lived on a bicycle and was always on the road away from home and/or power. My only other gripe is that I wish there was a software switch to turn off fast charging like Samsung offered. Sometimes I only have a fast-charge enabled charger around, but would prefer a slow charge.

I don't slow charge in the traditional sense, but I use a QC 3.0 charger for the same reason. It maxes out at 3A to the battery, or 0.6C charge rate. It's still plenty fast, but slow enough relative to battery capacity that it doesn't stress the battery much and no need to worry about turning a setting off in the phone.
Im using 25w adapter PD to charge V60, charging speed is too slow, need above 3hours from 10-100.
Checking battery in hidden menu, saw charong current max is 1,7A, usually lower.
Normal adapter give me same speed (like a cheap samsung fast charge adapter).

I am having the exact same issue. Have you found any solutions yet? I am about to either return the device or change the battery and charge port. Although, I am not sure if it will help because it has 10 watt wireless charging and still maxes out at 6 watts on wireless.

iam using Xiaomi 33w adapter with a Baseus cable, dont use Xiaomi cable (with red color inside usb port, this cable hold 5V only) .
This combo charing my V60 fast (about 1h30 -2h). Its acceptable for me.
Now i dont mind about charing speed anymore.
Hey bro i hqve a 36 watt fast charger. I noticed that my phone charges in 1 hour 40 min before. Now it still ahows me 1 hour 40 min but it takes hours to charge..... It is still showing fast charging. It never happened before

How do you charge?

There are so many options.
Superfast charging I find amazing. Quick plugin and the phone is back up to about 80% battery in no time at all.
Fast is ok. Just a little slower.
Standard is slow, it just ticks over.
I also notice that it appears to stop charging when the battery is full. Although I've stopped leaving my phone plugged in overnight.
But, I read that superfast might damage the battery and that's why it defaults to off. It's not a quick switch to enable/disable, so it's a decision to have fast or superfast on.
Or is life too short to worry?

Even if super charging would make the battery loose efficiency over time, I don't think it will be a noticeable problem during first owners time with the phone. I will upgrade in less than 18 months and I think most ppl upgrade within 2 years.

Fast wireless charger most of the time, but I did buy a couple super fast wired chargers to scatter around when I'm in a time crunch

Super Fast wireless charging all day everyday. I haven't plugged a cable into a phone since 2018. Battery life is solid so I'm never in a rush to charge a phone. Wireless is quick enough. I love the convenience of just throwing it in the stand without having to find the cable and stick it into the port. Especially in a dark room.
I've not really used wireless charging. So you have 15w wireless pads around the house?
Super fast charge too.
With PPS and the PD standard, it changes its power according to of the actual battery level and temp (and certainly more parameters) to avoid harming it.
I plug in every night, overnight next to my bed. Not fast charging, just regular charge, because it's not needed.
If you don't need to fast charge every day, turn it off. Doing it regularly will degrade long term battery life by a small amount. Both by the method of charging, and by the heat created by fast charging, as heat is bad for the life of a battery.
But all in all, it's not terrible. Just charge it howver you want. It's not going to cause any terminal issues. Just charge it when and however you want to.
I have switched off both Superfast as well as fast charging. Not sure if that will have any impact positive or negative as my opinion is that Samsung didnt go with 40W, 60W so on and so forth charging not because it cant do it (If Oppo,Vivo, Xiaomi can then Samsung definitely can) but as a bigger company they probably wanted to act more responsibly so they must have ensured that their 25W charging has negligible effect on battery and thats why they went with it. Just my 2 cents.
