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 Samsung Galaxy S7 can charge. A higher rating indicates that it charges extremely fast.

charging speed is fine, but anyway after quick charging the phone has like 20-30% less battery life ...

I am saying that battery life is incredible ... but I noticed when I charge the phone using fast charging from like 10% to 100% then it is loosing capacity much faster ... that is it ... I am still satisfied

Interesting, thanks.

I disabled fast charging since on my S6 Active it used to make the phone insanely hot and actually started burning the cable at the point where it connected to the phone.
That being said, I'm actually really impressed how fast this phone charges with just a usb cable from a computer or car usb port. Very fast charging without 'fast charging' enabled.

Charging speed.
There is only a 10 minutes difference between fats charging on and off on my s7. Is that normal?

It charge 0-60% quick but after that it charge normal speed.

I've also noticed that.. I thought was something with me, or it was just a feeling from myself!
But now I've seen more people dealing with same "problem" (if we can put it that way)!
When I charge with Fast Charging ENABLE, the S7 seems to drain battery faster then when I charge with Fast Charging DISABLE!

Totally agree! I had SOT time till yesterday about 2-3h...and yesterday i had to charge my phone with regular 2A 5V charger at work...takes 30 minutes more time but SOT was allmost 7 hours

I'm not comfortable with how hot my phone gets while fast charging. Reading this, I'll try turning it off. I'm also uncomfortable with how hot wireless charging makes my phone. I doubt I'll use it much unless the micro USB port goes.

How much time do you keep your phone in charging?
Mine is charging in 1 hour and 45 minutes, but i keep it 2 hours. ( I disabled Fast Charging )

maybe to reduce heat, don't wait until phone is <66% battery level to charge it up ?

About 1h wifi charging

Using QC2.0 charger is really quick.

Charges pretty fast, I turned off quick charging because my phone gets very warm.
10% in about 10-20 minutes?

I use volt meter with fast charge on get arount 1.7a and with fast charge off around 1.3a. It's pretty fast even fast charge is off

What wireless charger are you guys using?! Specifically you guys with hot phones. The reason I ask is because my s6 use to get hot using the standard samsung fast wireless charging pad. Now with the newer Samsung fast wireless charging stand it is cooler to touch. I also noticed there is a fan runing being the pad.
Perhaps the fan is helping keeping the phone cooler then other pads?!

But, with fast charge it uses about 9 volts wich means a max of about 15 watt.
without fast charge it uses about 5 volts which means a max of about 6,5 watt
So less then half max power without fast charge..
I haven´t seen the phone getting more then 1,4 amps on 5 volt even with stock charger..

Just nowI tried and get this. No idea @@

Well I don't need sugar+caffeine, but regarding the phone it takes at least 100 minute to charge from 1% to 100% on a power socket. On a USB port - I have not tried yet, but it could take double the time I guess.

Pretty crappy. This thing pulls about 1.2mA from the socket and therefore takes a while to charge up. Say about 2 hours to full from 10-15%.

Max amp draw I get. Same with a 10w USB charger or the one plus stock.

5% to 100% i only need 1 hour 40 minutes something. So its fine with me.

1.5 hours. Pretty fast

Better than Galaxy S3 (my former phone)

120 Minutes (2 Hours) from 5% to 100% for me.

90minutes from 0 to 100℅ which seems pretty fast to me as compared to other phones with "fast charge" which can take take 2h45m for full charge(4000mah)

Hi folks,
Last night, my oneplus X took almost 4 to 5 hours from 0 to 97% (not really 100%!). I noticed this degradation of charging since a couple of months, but i can not figure it out if it came from the battery or from the charger. I tried with another charger, and it takes almost the same time...
And also my battery seems to be less efficient, so i have to consider to replace it or there is another solution ?
Thanks

Well, this is an unfortunate tell of events. Onyx has a very very inaccurate fuelguager and it doesn't seem to adjust with time so as the battery degrades, it gets dramatically worse. I too have the sane issue and no matter what I do to circumvent this in my kernel sources, it always pops back up.
Point being, there really isn't a solution though I do soon hope to take a closer look at the fuelguager and rewrite bits of it in my kernel to improve its accuracy

I had the same issue. At some point charging became very slow. But if it's decharging at a normal rate, then it's not the battery.
In my case, getting the charging port repaired at a local phone repair shop did the trick. Now charging from 0 to 100% doesn't take 4 hours anymore, but again 1.5 to 2 hours.

enable USB fast charging in Kernel aduitor that also helps.
Keep mobile data off when charging that also speeds up charging.

Not sure if the phone is old. It seems slower to charge. 2 to 2.5 hours with no usage during charging.
Anyone face this?
On lineage 15.1 june build and usb fast charge enabled. Using stock charger.

Check charging rate with "Ampere" .
Then, try to unactivate USB debugging and check again (after plug / unplug).

Managing / monitoring quick charge

Hi guys .
I was wondering if anyone has come across an app or a method of telling which QC charging profile our HTC 10s are using?
As an example, my HTC is currently at 50%, and due to the fact I will be going out after work, I decided to plug it in to top up. My desktop charger is a QC 2.0 charger from Tronsmart - and supports 5V/2A, 9V/2A and 12V/1.5A.
Once I plug in, the phone registers the charger as a quick charger, and booting up Ampere reads a charge speed of 2460 mA at 4.217 volts = 10.3 W. Even if I take the standby drain into account (measured by Ampere at -360mA) = 2820 mA x 4.217V = 11.9W.
This seems a little ways off from the 18W charging profiles.
So, is there a set of environmental criterium that has to exist for the 18W profiles to kick in? if so - what are they?
or, is Ampere possibly unable to measure the amperage or voltage accurately?
or, is this effectively 18W, and there are 6W worth of losses from resistance or heat? (1/3 in losses seems a little high for me?)
PS, the cable I am using with the tronsmart is a USB A to C cable from Belkin, very thick gauge too.

Ampere can't see past the phones own battery charging circuitry and know what it's being fed.
If you really want to see what the phone is being fed, get yourself a USB power meter.
This guy sells those "YZXstudio" meters http://www.ebay.com/usr/f-t-2000

And in before you ask, yes they're QC3.0 compatible because backwards compatibility.
@Haldi4803 has ordered/received a power meter as well, don't know which one he got but he reported this in the megatech thread.
3. My Powermeter is here <3 gonna open my own Thread soon. Sadly the Bluetooth App failed so I don't have the charging measurement from 30-100% from last night. But.....
At 30% it charges with 7V !
071010,022593
7.1V 2.2A = 15,6W
When at 100% Idle Voltage is about 6,3V
When connected to the Powerplug and on 100% Battery you can Benchmark as much as you want, the battery does NOT Drop. So you can use this to control if Trepn Profiler is correct in Powerdrain.

Judging by the "bluetooth app", did you get one of these YZX meters Haldi?

Bingo
Soldered the additional Bluetooth module on and it's awesome!

QuickCharge.... like every other charging technologie tries to safe the Battery from harm. Therefore only on the lowest battery level you will be charging with a low of Watts. On 50% ? Well.... i'll tell you the next time my Phone is empty Benchmarking in Progress.....

Battery

Can I set my mobile to stop charging after a certain percentage?

I don't think so, only scenario I have seen regarding this, is when rooting, max charge level of 80%, but I know of this when I used a note 8

Could I ask why ?

They say your battery life decreases when you charge it fully. I got this off a site: Your phone's battery loses capacity every time you keep it fully charged all night, every night. About 20% loss per year!

My Tab S6 has even a setting to restrict charging to 85%.

Don't think my Note 10+ has that function:crying:

I also have the Note 10+ and I can confirm that, unfortunately, it does not have the setting to restrict charging to a certain percent.
You could use Bixby Routines to get a remainder (sound or message notification) when charging gets to a certain percentage.

That's a negative unless rooted.
Accubattery let's set an alarm that sounds even with the screen off (which it should be when charging).
Heat and voltage potential kill Li's. The higher the charge and cell temperature, the more damage.
•Li's love short partial charges midrange between 40-70% ie from say 45 to 65%. Partial midrange charging causes almost no wear.
•Avoid charging to 100%; best to stay below 80%.
•Avoid discharging below 30% or if you do only do a partial charge of 20-30%.
As you get nearer to the 6% limit the battery needs to provide more current to meet the fixed mobo V+/milliamp requirements thus more battery stress and heat buildup. Voltage converters need to work harder as well to step up the voltage for the mobo which also produces slightly more heat.
•Avoid letting the battery charge hot (above 99F).
○Avoid charging batteries below 80F and never charge if below freezing without warning phone first as it can cause Li plating which permanently degrades the cell.
Keep phone out of the sun; don't bake it.
•Don't allow a misconfigured apk(s) to constantly run it warm. Excessive current draw increases Li battery wear. An idling 10+ should be relatively cool to the touch.
Find the current drain(s) and correct.
•Fast charging is fine if you remember to not allow deep discharges.
•After about 80-90% to charge rate goes from 2%@min to 1%@min. 62-70% is an ideal charge stopping point for maximum battery lifespan.
○Never store an Li with less than 6%; charge when possible. Li's self discharge at a 2-3 rate per month.
They auto shutdown at 6%; if the voltage falls too low their protection circuitry will permanently disconnect the cell rendering it useless. It takes about 2-8 weeks for this voltage drop to happen in a cell at 6%.

Question Charger loosing performance?

Hello guys!
I have the EU model with 66W charger.
It was strange for me that my phone 1-> 100% charge was about 5-6 min slower than the time mentioned in the GSMArena test.
To see what is going on I got a cable which displays the actual performance the phone is being charged.
It was strange that at first the performance was fluctuating between 57-59W.
Then at about 60% the performance dropped to about 35W.
Then as the battery charge increased the charger performance continued to drop.
For the last 3-5% the charger only operated at about 20W.
Is this normal behavior for a charger? As the charge of the battery increases the charger lowers performance?
Sorry for the stupid question, I just thought that it always operates at 60-66W.

Probably normal. Fast charging always ramps down in steps as the charge level nears 100% to prevent Li damage.
Temperature and battery condition also influences charge rate.
6 minutes isn't much. Your battery may simply have a slightly higher capacity then the test one did

It is your phone that starts to draw less power from the charger as it starts getting full. This is by design and is done to reduce heat and maximize battery life.

Fast charging will not engage if the battery start temperature is too low or high for that charge cycle. Optimum charge start temperature is 82-90°F.
Starting below 72F or above 102F is not recommended. Keep battery temperature below 102F will charging, use cooling if needed. Failure to do so can cause Li plating which will permanently degrade the Li and possibly cause a failure.
NEVER attempt to charge a Li that's below 40F
Battery charging is a electrochemical reaction that requires heat to function properly... within certain temperature parameters.

Spot on - lithium batteries cannot be charged at the max rate all the time. Once the battery reaches about 70%, the charging rate drops off as it's slowly brought to 100%.
