as the title says, my G2 is charging at barely 500mA. while earlier it used to do at 1600mA. Now the charging speed is painfully slow.
Using stock charger and cable, just like before.
D80220b-HKG. Total Stock. Unrooted.
any solution?

wao
really helpful forum.
anyway i found the cause. Gsam helped a lot.
It's because of hot weather these days.
Normally battery temperature is between 30-35 °C. When i plug in to charge, it starts fine at 1600mA, but battery temperature also begins to rise and as soon as battery hits 36°C, thermal throttle kicks in and charging rate drops to 500mA to keep the temperature down.
In winter didn't have this throttling.
Also if the phone is turned off then it doesn't care about temperature and charge at full speed all the way. But when it is ON, it intelligently negotiates charging rate depending on thermal conditions.

i think this thermal throttle came in after recent D80220b update.
really annoying though. i have lost quick recharge capability.
any way to bypass it? 500mA is way to slow

Hi, where? in battery info?
Hidden menu, charging
So no solution guys?
If i turn it off and then plug in the charger, it charges fast like before (1% in 1 minute).
But when turned ON, it negotiate really slow charging rate and phone feels just cold from back side. When it used to charge fast, then little heat could be felt on back cover.
Right now if i want to Keep it ON and charge at full rate, i have to keep battery temperature under 35°C which can only be done if i keep it in front of AC or in refrigerator.
Gsam is just guessing the rate based o charge before and charge after.
When it is charging slow go to settings and batter and check what it's detected as charging with will say AC or USB.

my gf lg g2 doesen't charge.. 8 hours for a full charge..
i'll check for thermal issue, but why only few phones have that problem? i asked in a forum and many people with lg g2 saw that's not normal..

Turn off thermal throttling in the 'hidden menu'.
There is also a throttle for when the phone gets too cold, FYI.
Does charging the phone via the Samsung official wireless stand (or any other wireless chargers) causes it to have "less overall capacity" on the battery compared to charging it via USB cable? E.g. Once charged to 100%, does wireless charging provide less capacity compared to charging it via USB cable?
Note that I'm not talking about charging speed or rate, I'm more interested to know about the battery's overall performance when charged using wireless vs cable.
Same

Sorry, misread your question the first time.
No, 100% is 100%, whether you charge wired or wireless, fast charge or slow. The battery tells the phone when it's full, and the phone tells the charger to stop charging.
I always seem to have better battery when I use the plug instead of wireless.

OP is not talking about charging speed of the 2 methods.

Mine is very very slow, sometimes only added 1% after an hour of fast charging.
Though when i turn off fast charging on the phone, it charges normally (faster than when fast charging is switched on).
I'm using the Samsung original fast charger (the new tilted model) by the way.
Anyone experiencing the same problem? looks like a firmware issue?
Most times you have to reposition the phone until it says that it's actually fast wireless charging. Kinda Irritating. Also make sure the fast wireless option is turned on in the settings.

No such problems here. Drop it on the fast charger as it lands and away it goes in fast charger mode. Are you sure you have it enabled in settings......

What charger are you using? Are you verifying each time that it's actually fast charging?
Sent from my SM-G935T using Tapatalk
I use a Samsung fast wireless charger. Now I also remember that if you don't have the Samsung one then go to your local store where they do have one and land your phone on it. I read that the fast charging wireless feature only starts working after you use a genuine Samsung fast wireless charger, but remains functional thereafter.
Yes it says fast charging and I can tell by the short time from empty to full charge (usually around 1.5 hours) approximately.

yes as mentioned i'm using the original samsung wireless fast charger, the latest model which it's at an angle so there won't be the problem of misplacement. and yes again fast charging is turned on, cables, adapter are all original stuff that came with the phone.......

S7 Edge (Exynos), using Samsung tilted wireless charger with phone original adapter / cable. Phone it's saying fast wireless charging, but is only fully charging in about 4.5 - 5 hours (starting from 10% or lower).
Tests from 45% took same, about 2.5-3 hours.
Charging by cable: about 1.5 to 2 hours. Also saying fast charging.
Samsung is waiting for me with phone and charger to test them in their shop.
Will keep you updated.
agreed, have noticed that it occasionally shows normal charging rate when in fact attached to a quick charge source... reboot/replug always seems to fix but I've learned to check each time I plug it in so that I don't come back in an hour to find it's barely moved

Fast charging by cable, normally takes ~100mins from 0-100% on S7 Edge. However, my S7E has the same problem as yours with mine charging at average 25% per hour with and without the wireless fast charge option checked.
I bought my wife the convertible charger and it says fast charging but for instance the phone is on 37% and it says 2 hours and 6 min to full charge. I plugged it into the wall at 37% and it says 1 hour 8 min. Any ideas? I will return if I can't fix it that is unacceptable

First of all turn on Fast Wireless Charging. By default it's not on. You have to tap on the notification you get when charging starts. You are jumped to the charging settings and there you can activate it.
Second thing, Wireless charging is, as just said here, not as fast as wire in Fast Charging. Wireless Fast Charging should be something better then normal cable Charging (no Fast Charging).
Ok thanks. I returned it. I guess if that's the case I don't like wireless charging. And 90 bucks for something that's not fast charging sucks balls. Luckily I was on the 10th day of my 14 day trial

i looked like crazy but when i start charging, wireless or wired , when i tap charge, i choos advanced there i can only choose fast charge using cable
any ideas?
My device is taking more time to get full charge. Is anyone experiencing the same.is there any way to improve the charging
My device is taking around 3 hrs to charge fully which is quite normal as given it has 5000 mAh battery and no fast charging. Only way to improve could be to switch off and then charge or not use phone while charging. Disabling cellular data and WiFi may also help.

In my first time charge, i leave it charging when i sleep, but when i wake up my phone just have 82% battery, it takes 7 hour charge when i sleep, i realize that my mistake was not plug in perfectly the usb cable to charger adaptor, shame on me LOL
When it plug perfectly the charging time may 2,8 - 3 hours to 100%

Does it show "Charging Rapidly" state on the lock screen?
On my Anker triple ports QC2.0 charger, 2 of the normal ports 5V2.4A are able to "induce" my M2 phone to go into "Charging Rapidly" state. It only happens after plugging in for a few mins; if plug into the QC2.0 5V2A port it doesn't display "Charging Rapidly", just shows the normal "charging". Another of my QC3.0 charger 5V3A is also able to do this while other chargers I tried from 1.8A-2A range can't get this "Charging Rapidly" state. Is it possible that the M2 only support "fast charging" on 2.1A and above chargers?

No... Actually the speed of charging also depends on the current... If you current is 2A, then it automatically shows charging rapidly...
If you use any other charger with a lower ampere rating, then the phone will automatically detect that the current is low and it is charging slower...

Its just a suggestion... Dont use the S5 charger even if it charges faster... It voltage is 5.3v ... Voltage should always be 5v ... It will destroy your battery in the long term...

Yes ... You can... But your phone will probably heat up a lot.... And long exposure to higher temperatures might slowly degrade your battery...

Why do you say it will heat up a lot? Phones nowadays should have protection circuit to limit current, right? For my M2 I don't see any difference in using 5V2A or 5V3A adapter.

I might be wrong... Of course they have protection circuits ... I have another phone Galaxy E5. It also should have a protection circuit or whatever...
Its charger is rated 5V 1.55A... But when I use a 5V 2A charger, the phone starts heating up...
Though it happens only while charge is less than 100...
Upon reaching 100% it cools down...
