Hi everyone,
I recently purchased S20FE 4G in India. I also purchased a 25W charger from Samsung.
I'm very disappointed with the charging speeds.
I switched off and charged and these are my results:
25W took 1hr25min to charge 5to100%
15W took 1hr38min to charge 5to100%
I even formatted my device but no improvement.
Can you guys mention your charging speeds?
What can I do as service centers are closed due to lockdown.
Thank you.

Yes, I enabled after formatting.
I think it's a software bug as many users are complaining about the same on Samsung Members app.

I've heard people mention it on reddit too. weirdly the standard 15w charger hits around 3000mA if fast charging is enabled.

Mine 15W gives upto 1500-1600mAh max then drops to around 1000mAh.
25W fluctuates a lot. Gives around 1100-1200 only

It should hit close to 5000ma at times with 25 w brick in the 20-70% charge range.
In that range you should be seeing 2600-5000ma.
Fast charging will noticeably start ramping down at 70-75% and will completely slow charge after 90%. Best to stop charging at 70-80%.
If the start temperature is too low it will revert to slow charging for the entire cycle.
Best start temp is 85-90°F.
Cool it if it starts getting near 100F.
Use a known good Samsung OEM 25w brick/cable.
Try toggling to fast charging switch on/off 3 times.
Factory resets* will do nothing except waste time.
Clear system cache, try a hard reboot.
Watch for any signs of bulging on the front and especially back of the phone. Li's can fail at any point in their life. A failed Li will fast charge erratically and have reduced capacity. Any swelling means it needs replaced asap before it damages the display or worse.
*a major firmware update is the exception

I'm hoping for a software update to fix this bug. My 25W never goes beyond 4000mAh.
It takes 1hr25min to charge from 5to100% when the mobile is off.
Should I downgrade to March patch using odin?

4000 ma is acceptable.
Having the screen on will skew the charge cycle, don't.
It takes much longer to charge past 80%
Temperature parameters can greatly alter fast charging times.
Don't routinely discharge past 20%, 40% is a better cutoff.
Charging to 100% is slow and the most stressful thing you can do to an Li except for... doing a full charge cycle charge (5-100%)
If you're seeing roughly a 2%@min charge most of the time in the 40-70% range it's likely fast charging normally.

I see 1%/min charge. Around 40-70% it increases to 1.5%/min.
Overall charging is slow. I've seen more than 10 owners complain about their S20FE.
It's a software issue after April update in India.

Try reverting Device Care and Device Health Care to factory load.
My Rule #1 if your OS platform is running fast, stable and fulfilling its mission... let it be.
I'm still running my N10+ on Pie, zero issues.
Too many firmware updates skew the stew

Yeah I've learned that the hard way more then once! Firmware updates can (and do) cause permanent damage to the device with a reflash being your only recourse. This can get real messy too.
In reality even outdated Android OS's rarely get infected unless you do something really stupid.
Any OS that is Pie or above is immune to the worst rootkits that can cause "unremovable" infections.
As you can see even a factory reset caused by malware be less trouble than a buggy firmware update to fix.
Always backup your critical data at least 2X on 2 or more hdds that are physically and electronically isolated.
Crashes are rare but they happen.

When I got mine, it was enabled already.
Oh, if your fast charge your battery once, does it reduce your battery's lifespan in the long run, or does it need to be fast recharged several times for a notable difference?

As a general rule, the faster you charge the battery, the hotter it gets. The hotter it gets, the more quickly it will degrade. I still use my S3 charger to charge the Note 4 overnight.
Does it really make a noticeable difference? From what I've read, probably not. But I don't think there's been much objective testing. Just using fast charging once is highly unlikely to affect it in noticeable ways at all.
If you've charged the battery once using the fast-charging method, is that going to impact the lifespan of the battery? Or does it take multiple fast-charges for the battery to begin to loose its charge?
Nowadays I use the regular 2amp Samsung charger that came with my Wireless Charger.

I edited that in right after I posted, but I guess you beat me to it. As far as I can tell, it's a gradual process. Unless the phone seriously overheated during the one charge, it shouldn't have much effect at all.
Thanks, looks like I don't another one of the Fast Adaptive Chargers after all, haha.

Honestly I'm not sure if it diminishes battery.
I have to take it off because I'm using a Zerolemon battery and it doesn't charge all the way up unless the fast charging is off.
The adaptive charging is built in as long as you're using the included charger. It charges at a higher voltage so it's not as damaging as say, a 3 amp charger would be, but it takes many many fast charges to affect the battery's performance. Generally speaking though, the faster you charge the more capacity you lose over time, but the worst thing you can do is charge it &leave it plugged in for hours fully charged. I use an old Bluetooth charger that's 500mah when i charge overnight & the fast charger at work or in the living room.
Hi guys so the note 9 is becoming hot while charging it has started happening the last couple of days. When I first got the phone on release it would never get hot. Any ideas?
Sent from my SM-N960F using Tapatalk
Have you noticed any change in charging times? That heat = wasted electricity which has to come from somewhere. There is only two places that heat could be coming from (afaik) are the processor or battery and it's charging circuity. Could be that the phone is doing a bunch of updates when you plug in the charger, if you have auto updates on or perhaps you had fast charging turned off before.
No updates phone has all connectivity turned off back gets really hot and yesterday the charger stopped charging the phone so I got the charger brick replaced and charges fine but seems very slow to charge and fast battery discharge

Turn off fast charging. I believe, even normal slow charging is fast compared to iphone 8 plus fast charging.
charging any device while it's on will probably produce some heat.
just seems logical and I don't consider it an issue worth worrying about. it all depends of what your measure of hot is.
if your cable, port and charger are all mint, then all should be good.
if your cat bit the cable then look no further.
your alternative:
shut phone off and charge it.
it won't heat and probably charge in 20-30 mins to full charge from 0%
if it still got hot while charging at off then you may have hardware issue with equipment/phone

The heat is caused by the charging process, so the phone should heat up whether it's turned on or not. The voltage has to be dropped from the 5/9V input down to the ~4V that the phone battery charges to and that is not a 100% efficient process. The internal resistance of the battery itself also causes some heat.
Also there's no way you'd charge a Note 9 from 0 - 100% in 20-30 mins. Even factoring in no charging efficiency loss, you're looking at 51 minutes to charge a 15.4Wh battery with the 18W from the Samsung charger.

I dont need any convincing lol
but the heat we can actually perceive on the phone case while it's on versus it's off is 2 things. dont think we can feel it while it's off. if I crack the phone open and touch the battery then yes obviously.
now for the 0 to a 100 in 20 to 30 mins while phone is off, I'll time it. but I'm pretty sure I'm not off by that much. again I'm not the one needing convincing in this thread.

Your phone should be almost exactly as hot whether it's turned on and not being used or turned off. The tiny amount of energy it takes to run a phone while it's dozing is nothing compared to the amount of energy dumped into the phones body while it's charging.
I'll happily test it but unless the charger suddenly starts outputting more than twice the rated amount of power into the phone when it is turned off, it's just not physically possible. Not trying to convince you, just trying to correct misinformation.

Mine is becoming a little hot while in wireless charging pad, and after complete the charge (at 100%)
That is normal however it should cool down once your battery level is charged above the 50% mark.
Try installing a battery log app. I use this one and it records battery temp so you can look at that after it is done charging to see how hot it actually got.

My S21 Ultra is taking 1 hour & 30 minutesh to charge from 5-100% with the Samsung 25W super fast charger and the cable supplied with the S21 Ultra.
And I have fast charging and super fast charging enabled on my device.
All the user reviews & battery charging tests online show that the S21 Ultra takes roughly between 1 hour 9 minutes to 1 hour 15 minutes to do a full charge from 0-100% with the Samsung 25W Super fast charger.
Any idea what is going wrong here? Is it an issue with the phone, cable, or charger?

Make sure you use official 25w pps wall adapter. I'm using electjet 65w 3 port adapter as it fit the best replacement for my needs. Its also a good value on amazon with fast shipping. Official samsung should work too but so far I get around 1 hr to full charge from 3% if i leave it alone.

But that isn't the issue, is it? There is some fault here because of which my phone isn't charging as fast as other people's phones.
Regardless of the damage to my battery life, I should be getting the charging speeds that everybody else is getting with the S21 Ultra. Everyone who charges the phone from 0-100% gets a full charge in 1 hour 10 minutes. I'm trying to find out why that isn't happening with my unit.

What's the start temp at charging?
Is it exceeding 100°F when charging?
Have you tried another OEM 25w brick/cable?
Make sure plug is fully inserted into brick.
You tried clearing system cache, hard reboot and toggling the fast charging switch on/off 3 times?
Is there any case bulging?
If you're within your return window, get another one instead of going down with the ship.

One factor that all of those YouTubers fail to mention is the temperature of the room that the device is in. Sure they take the temperature of the phone itself, but none of them take into account the room's temps. They don't seem to care about a more scientific approach, just AdSense payout.

At 98F unless you cool it if fast charging* engages it will quickly reach 101F or so and then either ramp the charging rate down or stop charging altogether.
It's possible the battery is damage or the C port PCB is defective. Both will cause erratic fast charging.

Once the battery temp is at 98F you need to cool it. A damp microfiber cloth and a fan work well in dry climate.
You want the battery temperature between 85-95F for best fast charging rates. That's what I've observed. You'll get best results doing midrange partial charges to below 72% ie 40-70%

Look they don't always fast charge at the same rate even when working correctly.
My latest charge log... this is at near ideal temperatures too.
You can see when charging in the midrange that averages about 2%@minute until 70-80% where it frequently starts to ramp down.

Yeah I know... that's for the next phone.
I did the same thing you're doing until I realized I could use the SD card as a data drive. No more 6+ hour reloads.
I doubt a factory reset will help but give it a shot before taking it in for service.
Just keep an eye open for any signs of battery swelling. If the charger and cable are good it's probably the C port pcb.
Noticed on battery health monitor battery seems to be getting rekt quickly
Should I charge slower or something ?
At this rate the battery is degrading 6%+ a month!
Pretty sure that's not accurate. I stopped using Accubattery a long time ago, I just use my phone like I normally would and I try not to worry about the battery degrading.

When I test it on my old Huawei mate 20 X it says the battery is only 74% effective and it was 101% when new
I am not sure accubattery is legit or not but I never take their recommendation to only charge between 30-80% because I need to use the phone capacity from 100% to whatever and I don't plug it in until 1% or sometimes dead which is supposedly the worst thing you can do lol
I guess New batteries will be cheap by the time I need one , haven't seen a tear down yet of this device to know if it's easy to replace it yet or not....
This application give me 5115 after 2 weeks.
Dont' know if accurate or not.
I don't think they know that battery in MI11 Ultra is made with new material "silicon-oxygen anode battery" as app probably thinks you have normal "li-pol battery" so when you charge it with high power, app think you killing your li-pol battery?..

Noticed on battery health monitor battery seems to be getting rekt quickly
Should I charge slower or something ?
At this rate the battery is degrading 6%+ a month!

I just tested what it looks like for me after about 2 weeks.
I have almost the same result as you.
I really hope that's not correct, otherwise I'd be worse off now than with my Galaxy S20 Ultra (SD version) after a year.

Yes, rather shocking results for a month , i don't mind changing battery every 6-8 months because I'm a heavy user ( but hopefully spare batteries are available? )
Once they get down to about 82% I usually order a new one and change it and it makes a big difference in the longevity of the devices
i have the phone since it launched ( received about 1 week or so after ) and in the app i have 98%.
I do believe the app is not accurate enough tough.
My mi9, after 2 years of intense usage still is at 90%

Removed Dbl post
I did a factory reset since last time, and i have same result.
But i don't think it's accurate, in my case i have too high result to be true.
Android doesn't directly monitor current draw I don't think so no app will be accurate.
Regardless Li's like frequent midrange power cycling 40-65% is ideal.
Avoid charging past 80% or discharging under 30% when possible to reduce battery stress.
Do not start charging a battery under 72°F, NEVER charge one near freezing.
An 85F start temperature is best.
Keep the temperature below 100F during the charge cycle.
Low temperature charging can cause Li plating which permanently degrades the cell.
Most fast charging controllers will not let fast charging engage if the start temperature is too low or high.
37-38 C temperature during charging is somehow difficult to keep with the 65-67w charging speed without any external help ( a fan for example )
But in theory you are right

I use a damp microfiber cloth and/or a fan.
If it gets much above 101F charging will likely terminate. That max will vary by device however it's counterproductive to charge at this high temperature.
I usually use my blackshark fan with great success. That little device really works

You got the idea
If i use the official fast charger .....charge up to 100% the next day I barely get 16 hrs and 3 hrs screen time..wireless charge slowly and I get 30 percent more .
Anyone else see a difference??
Uk unlocked s21u for reference.
You sure there are no other factors involved?: types of apps you ran, heat, etc.

That sounds interesting! Would love to look into this a little deeper.
Could you describe this in a little more detail please? Like when do you start charging, how long it takes with each method, what your usage pattern is like, and what you mean by 30% more (SOT, Standgy, or literal battery percentage remaining)? And any relevant screeenshots would be much appreciated.
Fast charging will not engage if the temperature is too low. It will remain disengaged for that charge cycle.
Charging is an electrochemical reaction that needs a certain temperature range to function properly.
Minimum start temp is 72°F but 82-90F is optimal.
Anything below 72F brings the risk of Li plating which will permanently degrade the cell.
Charging will also shutdown if the battery temperature goes too high.

I don't think OP is talking about speed of charging. We're trying to discuss battery life with different speeds of charging.

It should be near identical.
Android battery capacity sensing always left something to be desired.
Battery temperatures should be made the same when comparing.
Try comparing battery voltages rather than indicated %

Depending on how fast the battery is charging it may shutdown at a lower charge level to avoid overshooting the correct shutdown voltage.
Samsung is said to be very conservative with their charge curves... I wonder why
Samsung should be using graphene batteries by now. Instead of throwing all their resources at the Folds, which never have sold well, they neglect their bread winners. I just reamed them out over that today

Said they should be using them already, among other things. Before the 10+ was released there was speculation that it might have a Graphene cell, lol.
I was barely aware of this technology until a few days ago... it be cool and it's in use.

Xiaomi tells us about graphene batteries and the great challenge posed by the Mi 10 Ultra

30% more seems to be a huge claim .
5%-10% could have been a margin or error.
I'll have to do some tracking and get some screen shots . I normally wireless charge overnight and it says 100 % every morning and I use 70 % battery on average . But 1 day a week I have to charge using the lead . I only have the "super fast" charger and lead and the next day the battery is always worse by quite a way . Dead by 19:00 hrs. Similar usage most days . Its as if on fast charge it says 100 % but is way down.
As said I'll do some more investigation.

You know that you can toggle OFF fast-charging and super-fast-charging in the battery settings right?
Try that.

Samsung better listen then.
These batteries should last us 4 years easily. Anything less than that is a rip off.

With heavy usage the Li's are good for 1-2 years. Maybe better in a temp controlled environment.
I stream a lot and that's hard on the battery which is why I now say... live and let die
It's typical for batteries to last longer the slower they're charged. If you're using fast charging when plugged in, you'll see a decrease in the amount of charge that is held throughout the day, compared to wireless charging which is quite a bit slower.

Are you sure there aren't any other elements at play? Examples include the applications you used, the temperature, and so on.

So you're saying if one battery is slow, one is fast charged, both to 3.2 volts, the slow charged one will yield mAhs.
Unless the battery is degraded I have my doubts that it be a significant difference.
