Hello Guys!
I got today a new P3110 and I discacharged it to 2% and I plugged it now to load.
I have seen the charger pushes 2A @ 5V , this is pretty much for a battery of 4Ah, I know from my batteries ( AA AAA and others) that the charging current should be max. 1/3 of the capacity of battery.
So my question is: IS it better to charge it with the Samsung Galaxy S2 charger which provides only 0,[email protected],1V ?
It would last app. 6h to charge it till its full ( can be done over night, hopefully the charger wont melt)....
What do you think about that? Woul it harm to battery(li poly) to do it with small current?
cheers
If the charger seems much then tell me why Samsung made it.

to destroy the battery faster, through much more currency than actually needed, so you have to buy a new one....

You have got to be kidding me. ITS SO THE TAB CHARGES FASTER. IT WON'T KILL THE BATTERY!!!!
Its because the tab has a much bigger battery 4000mah vs 16xxmah.
It charges it faster

Of couse it charges faster, but for long therm it will kill the battery faster. Its usual, like every battery. Every fast charger is not good for battery, I just wanted to know if somebody have a expieriance...

Battery life span is a matter of charge cycles 0%-100%-0%. That is 1 cycle and surely batteries don't discharge to 0% not charge fully to 100%
-AFAIK- Even with lithium, Its the heat build up when "fast" charging that shortens any battery life - (same with fast discharging- I would never use those apps that do so) , so I agree with shOne. I have the same model & have noticed the battery does get quite hot when mains charging,( though have never thought to check charging AH).
I would imagine that the only damage you would do with using phone charger would be to the charger, by sucking out more than it can handle, not the battery ! -
-- But why not charge it via a pc usb port - this take a lot longer (so presume much lower AH) than the mains plug in charger - Most usb pc ports are nowadays - permanently live, even when pc off - same with the usb on a modern sky/virgin box. My battery does not get hot, charging this way. I dont know what the charge rate is charging this way ,because both the inbuilt notification & my battery app say "discharging" - (although actually charging)
(I agree that Samsung have provided a quick mains charger, and wouldnt be averse to selling replacement batteries earlier than would otherwise be neccessary, !! (I wouldnt use cheap replacement batteries in any I.T. stuff - I "blew up " a laptop once as a result!!)
I believe that the 2 amp charge is reasonable with the out put of most lithium batteries for this type of device. Since it is a lithium it will not be overcharging or over heating due to sensing, it would be a serious fire hazard... fyi I use a2 amp charger from Wal-Mart and I do not notice my device really heating up...

Agreed. The worst I got was a cheap replacement off a street without a packaging for a dollar. When I plugged it in for a few minutes the battery turned extremely hit and the battery expanded as if it was a puffer fish that took an electric shock

LOL.........mine was a supposed "genuine" DELL replacement battery I got on EB from HK. On the first charge (in the bedroom) heard a strange hissing then a loud "pop". Some of the underside casing was actually melted and there was battery gunge all over the internals!

A lot of things I bought from Hong Kong off Ebay actually came from mainland China pfff.....
It's those low quality defects they send you. Mass market goods in china doesn't require quality passes unlike Hong Kong where it's illegal once they get pass customs.

OK, electronics 101, chargers DO NOT PUSH power to a a battery, 2 AMPS is the chargers MAXIMUM OUTPUT, the device plugged to the charger PULLS what it wants (up to a maximum of 2A of current) so it can charge in a reasonable amount of time, you may be able to charge your tablet with a lower output charger but all it would do is take longer to charge (if the charger even had the power output greater then the static draw of the device), which is why most tablets simply CANNOT be charged by the USB 2.0 port on a computer or other small .5 A output chargers. You may very well charge while generating less heat, because of the slower charge cycle using the .7A S2 charger, but at the same time if you try to use the tablet while it's charging on the smaller charger it may very well drop in battery percentage as the smaller charger may not be enough to maintain the current requirements to charge the battery and run the device.
So in short, would charging with the smaller charger harm the battery, NO, but if it is enough to actually charge the device it will take atleast DOUBLE the amount of time to recharge as it would with the regular 2A charger.
What temp does your guys phone charge at? I recently got a new cable and i was charging at around 37C-38C the phone felt pretty warm at that point too, and the estimated charge time was practically cut in half from when I used my old charger. I wanna say my old charging temp was maybe 34C.
I know hotter is worse, and the slower the charge is better, but how much worse would it be at that little temp difference?
That's like 104 f . Not too hot. Streaming Netflix outside I got it above 110 and it's fine. It has a shutoff function if it gets too hot. No worries.

I can't really comment on the HTC charger since I've never used it but I use an old Samsung 500mah charger and it charges around 25-28c
Hello.
Can someone explain me how on earth does fart charging works on this device?
I've tried the included cable and charger, third party chargers and i don't see any fast charging going on?!? or any indication on screen that it's happening.
I've read somewhere that you need a special cable to use with the included charger (?!?!) is this true? where do you get this cable?
Phone is amazing but the charging part is really is really weird if you ask me.
Thanks.

do you get any message saying fast charging?
it doesnt show any fast charging message, so i wouldnt rely on such a message to make sure its working. just use the included cable and charger and ull be fine it takes about 2.5 hours to charge from 0-100% via fastcharge

Yeah ...That's why I asked. I plugged a meter to the charger and never saw it go more than 5v 2a.
I think it needs a special cable for the 9v but I can't find any info.
2.5h is not fast charge. My old s6 edge plus used to take around 70-80 m from 5-100% if if you put the remaining 1000mah shouldn't take that long lol
Mean in 30 min 40% recharge . My phone 0 -100% charged in 2:00
trust me, it is fast charge
calculate for yourself: original huawei charger is rated at 9V 2A, thats 18W total. 2A is 2000 mA. mate 8 battery is 4000 mAh.
best case scenario: 4000 mAh / 2000 mA = 2h
now add to that the extra time it needs to charge from 85-100%, because at 85% it automatically slows down charging to prolong the health of the battery and youre at the 2.5h FAST CHARGING time
also, i dont believe for a SECOND that the S6 edge+ charged that fast in your case. check this review: http://www.trustedreviews.com/samsung-galaxy-s6-edge-plus-review-battery-life-and-verdict-page-6
"Fast charging comes as standard with the S6 Edge+ and it works. It charged from 0 to 100% in just 1 hour 45 minutes. Samsung claims wireless charging has also been improved – it’s 27% faster on the Edge+ compared to the normal S6 and S6 Edge."
so thats 105 minutes for 3000 mAh. add to that 33.3% to get to 4000 mAh and u get a total charging time of..... 140 minutes. which is 2 hours and 20 minutes

I will make a full test from 0 to 100. I only charged from 40 to 100 and it took way more than 2 hours... that's why i asked if any special cable was needed. And as i told i mesured the charging rate coming out of the charger and never passed the 5V.
As for non Believing. It's REALLY pisses me off when people write that crap. Why would I lie? what would i gain from it? I sold the phone because i wasn't happy with it.... On the contrary and in case you don't know most sites like the ones you post are PAID to give positive reviews.
I checked with including charger and cable and the app Ampére and it charged with 2800mah. So, in ideaal situation it means a charging time of a proximity 1h and 26min. That means "fast charging". At least in my opinion. ?

that doesnt make sense what ure saying because in this case the site actually stated a HIGHER amount of minutes that it would take the s6 edge plus to fully charge from 0-100% so what now, theyre getting paid to write negative reviews as well?
also, no, ure not "gaining" anything from that, but people tend to exaggerate a lot, do a quick "drive by" in a thread and post random statements based on non-correctly remembered experiences and this is exactly how false statements are converted into "truths / facts". read my post and tell me where exactly i listed anything wrong. check various reviews on the mate 8, they all stare the same thing: about 2.5h for a full charge, give or take 10-20 min. it also compares perfectly with the charging time of the s6 edge+ in terms of mAh/min, and in fact these two phones are indeed VERY close, mate 8 being at 49mAh/min and the s6 series at around 50-52, so just marginally faster... which, again, is also represented by the numbers i listed in my post before
and again: there is NO extra message or notification stating ure in fast charge mode on the mate 8, it just does its job, thats it!
if ure getting slower charging rates / voltages, make sure to use the original charger and original cable and both with a proper high voltage power outlet.

I noticed the fast charging only really kicks in if you leave your phone alone. But if you keep using it while it's charging, it just charges at regular speed. But the moment I put the phone down and screen of for 5 minutes, it quick charges like crazy

I hadn't tested this. After i turn off my phone, a few minutes later it jumps to 9V 2A on my meter. If you turn it back on it goes down to 5V 1A. Must be a phone security thing, which is kinda cool in a way if you ask me.
Btw Apparently quick charge works with non original chargers too. I have a Cheotech 60W 6 port usb with 2 Quick charge ports (which supports 9V 2A/ 12V 1.5A) and it works Using the original cable though.
Don't use fast charging unless you really need it.
Always fast charging overnite (when you're not actually using the phone for many hours) can only shorten your battery longevity more quickly then with normal charging.

When I'm going to recharge for many hours overnite I use a 1A travel charger.
i guess thats the best way to restrict charging amperage although it shouldnt hurt the battery so much, considering that the amperage drops off sharply once level reaches 85% and above...
Sent from my Huawei Mate 8 NXT-AL10 using Tapatalk
Charging a phone with a lower rated current, will cause the charger to "try and match" the current requested.
Amps work in that manner, the device determines the draw. For example, using a 5v 5a (theoretical device) on a 5v 1a device will likely melt your adapter / screw up your phone from improper voltages.
In that case, an adapter may heat up, or if its smart enough (unlikely), it will turn off periodically. Most of the time, it will have an unstable voltage (undervolting) which is how some phones are able to detect an improper charger is used. This is bad for your battery.
I do not recommend charging with a charger that isn't rated for it. This is widely documented.
Is anyone else finding that the charging on the gear s3 takes forever? The moto 360 you could easily top off in an hour or so, but the gear s3 seems to take 2 and a half hours to charge fully! I mean phones with 3000 mah batteries charge faster than that.
Mine charges a bit faster than 2.5 hours (although I never drain it to 0%), however the slow charging time can be related to wireless charging.
Take a phone with a 3000mAh battery, and try charging it wirelessly and you'll see what I mean.

I have done that. I still think the phone takes maybe 4 hours... But the battery in my phone is nearly 10x as big so it should take longer. I just wonder if it is something off about the charging solution Samsung is using because they seem to not be using the standard qi wireless charging.
I suspect Samsung has slowed charging time down and is being over cautious after the Note 7 issues.
yea the charging time is slow on mines too. this is my first smartwatch so cant really compare it to others
It's because the charger is only a 700ma
Try putting the watch on airplane mode while charging. You're not wearing it anyways so give that a try. Especially if you have the watch set to connect automatically to WiFi or LTE when it disconnects from Bluetooth and you walk away out of range.
Hello everyone, i just bought a new wireless charger form Baseus and charge my s21+ with fast wireless charging on, and while charging i notice that the phone battery get as hot as 40 degree Celsius. SO i try turn off the fast wireless charging option and let the phone cool off to ambient temp (around 32-34 degree) and charge again, but it still reaches 40 degree.
I want to ask is this normal, and please share your temperature while using wireless charging and the brand of charger you use.

Well, phones getting hot while charging is usually normal.
Sometimes it happens when the phone charges for too long and at a higher voltage and amps.

Yeah, fast charging is faster, and wireless charging sometimes in some phones is hitter than cable. Depends on the manufacturer of the phone and the model and the wireless charger itself.

Hmm maybe it would be online, I don't have the particular phone and a thermal imager so i wouldn't know exactly.
Hi guys, hope it's ok I ask a similar question here.
I do to have S21 5G (exynos) and samsung 15w wireless charger with 25w brick.
The issues I'm having is with charging speeds. If I use fast charging, the current is around 2700mA. But as soon as the temperature hits around 35-36 degrees charging current starts oscillating between 300-600-900 mA. It takes around 5 hours to fully charge the phone. It's faster if I turn off fast charging. It takes around 3 hours.
Room temp is around 26 c.
I don't remember having similar issues with S20.

Fast charging increases the wattage of the charge so your phone overheats.
If it overheats too much the phone limites the charge rate to protect the components.
It seems like a flaw in the fast charging or smth like that
keep fast charging off if it overheats your phone, and maybe try keeping it in a cooler environment
