[Q] Slow fast charge?

Is everyone really getting the 50% charge in 30 mins? It feels like I am getting about 1% per 1 min of charge time on average. Not sure if that is normal or I have a defect somewhere? Also, is fast charging safe to use for every charge session or is it meant to be used once in a while for emergencies? Thank you.

yes my phone will go from zero to 100% in an hour no problem when using charger that came with phone

Really? Did it charge like that from the very beginning or did it take a few charges to get to that speed? I think it takes me like 1.5-2 hrs from real low to full charge with fast charge enabled.

I used to get those insanely fast charge times; however, recently my phone has been charging slower (with fast charging on). Not only that, but, for some reason, the original wall adapter stopped working twice now. The first time it freaked me out because I thought my phone was messed up, but it turned out that everything was working except the adapter. Then later, I found out that if I reboot my phone with the adapter plugged into the wall, the charger will magically start working again! This worked for one or two charges. Today, I found that my phone was, again, charging extremely slow. Not only that, but my phone stopped charging after around 50% and the adapter is broken once more. I've tried the reboot thing three times and it didn't work again T: So now I'm kind of worried my phone might be defective?
Has this happened to anyone else with charging issues?

I haven't ran into anything like that yet. Who is your carrier? Maybe you can take in your charger and battery to get it replaced? Can you try charging with a different quick charging phone or something to narrow down if it's the phone or charger's fault?

Although I am fairly certain that my issue was the wall adapter portion of the charger, I just found it strange that the fast charging function failed to work properly around the same time when my wall adapter started to fail. Hopefully I am right and nothing else was wrong, but I thought that I would say something in-case I was wrong
As for getting it replaced... I bought my Verizon Note 4 at BestBuy off-contract and when I went there, they claimed to not have any in stock. They never really bothered to ask if I wanted to replace it even though I brought all my receipts and junk so I just took that as I wouldn't be getting a replacement haha :crying:
If anything I'll probably end up just buying another fast charger from samsung later, but for now slow charging is fine I guess. The fast charging did make both my device and charger hot, so maybe that was the problem?
edit:
I do not have any other quick charging devices (to my knowledge), but the wall adapter - combined with various other cables - continued to fail with my other phones as well.

I also say about a hour for a full change

Weird, I need like 1.5 hrs to get from 15% to full on fast charge and about 1.75 hrs for 15% to full on slow charge.

i timed my 1st charge. 57 min from 0 to 100. phone turned on and screen off.

Yep, to me that's the best feature. No more battery switching.
I even bought the Verizon vehicle charger with fast charge, and it works just as quick

Do you know if it's safe to use fast charge for every charge up? If it shortens battery life over time, I'd like to know this now and only use fast charge sparingly.

Yes. It shortens battery life. By using the only charger they give you, you essentially cut your battery life in half. It's a conspiracy by Samsung and the makers of the materials used the batteries

Pretty sure that was sarcasm. I'm less sure about your comment, though. ;P

I read it in American Android, first December issue. They did a study. Only way to avoid the battery dissipation was if you only used the fast charger at night, and Sundays after noon, but before 1pm PST. fascinating article. It's amazing what a group of students at Yale who love Android can actually accomplish.

I think I can work around that charging schedule. I am also going to subscribe to that magazine now.

Slow Charging Issues

For the past few days, I've noticed very slow charging on my Pixel even if it says "Charging Rapidly". However it would say it will take around 3 hours to fully charge. When fast charging works, usually clocks at 1 hour and 30 minutes.
I really don't know what can be causing the issue. It's the original charger, and cable. Normally removing the cable and putting it again would fix the issue but it's becoming a common thing for it to take 3 hours.
I remember a similar issue on my Nexus 9 and cleaning the cache would completely fix the issue, but the Pixel XL is missing the Wipe Cache option in the recovery.
Any similar experiences?

On the OEM included charger?

Yup.

Could try a factory reset.. probably the only software related solution. I can't remember, but Chainfire may have said that the cache.img was one of the things that got removed in 7.1 so I don't even know if you could wipe it if you wanted to. You could also hit up Google support... maybe they'll send you a new charger to try. Make sure you're using the OEM cable too, at least for now, until you figure it out.

I had this exact issue with mine, factory reset / charging in safe mode didn't work.
Turned out to be a faulty usb cable but Google insisted on replacing the entire package (handset etc) Replacement works fine

If it makes you feel any better, Google exchange process is amazing.
Raised the return on mine about 4pm and the replacement was on my desk 9am the next morning, they also give you 14 days to send your old one back so you're it without a phone.

I use ampere to see what the charging rate is and I don't feel like the fast charge is that fast.... My 6p charged at a faster rate and my pixel charges at a faster rate using my Choetech smart charger. I'm going to have to drain the battery and see how long it takes to fully charge with the stock charger

When I checked mine it was charging at something like 2600-2800 but i only watched it for a few minutes, might have gone higher

Some phones ie lg v10 do not "fast charge" while screen is on (while youre looking at it) to avoid overheating. Ampere cant show max charging rate. I use a usb sleeve (usb doctor) that displays that info or turn on notification display
EDIT: Supposedly Pixel do not fast charge while in use either.

I think I can confirm this. Last night mine showed 27 minutes to charge from about 50% but after keeping the screen awake for about 30 seconds, it went up to 51 minutes.

I also find my Pixel charges very slow as well even though it says Charging Rapidly (OEM charger, cable). The GSM Arena review said they went from 0% to 46% in 30 minutes, I get more like half of that at most. I used Ampere and it said i was only charging at 710 mA.....

If you charge it from almost empty it charges very quick, but slows down once it gets nearer to full

Yes i started charging my phone when it was 4%, and when i looked at it about 20 minutes later it was only at 16%. I think it took about 3 hours to fully charge. The only modification I've made to the phone is unlock the Verizon bootloader and flash the P software (which was subsequently updated to V). I'm seriously wondering if the charger or cable is defective.

Charging stuck at 98%

Since I received the band, I can't get past 98% when charging. Tried charging from 30%, 60%, putting it on charger several times when at 98%, but I've never seen 100%. It doesn't have impact on battery life, just my slight OCD suffers I'm using 2A wall charger, so it should provide plenty of current. Any ideas except completely draining the band? I would like to avoid it as it damaged the steps counter when I completely drained the batter on Mi Band 2 (had to completely discharge it again to fix it).

Of no help whatsoever, but mine is also stuck at 98%. Fully discharging the battery does NOT cure the problem, so I have left feedback on the Mi FIT app. Everyone needs to do the same

Well, at least we know that trying the complete discharge doesn't help and that I'm not the only one with this problem. I sent the feedback, even though I doubt that it will be fixed. But maybe Xiaomi will surprise us..

No, if enough people have the same problem - and report it - something will be done. Most of the new features we have on the Mi Band 4, were added after they received feedback about the disastrous Mi Band 3

I just got one and have the same issue. Glad I'm not the only one! I'll submit a report to Xiaomi.

Funnily, I was able to charge to 100% two times recently. No idea what was different then, but my last charge was again only to 98%.. Go figure.

I have the same problem!!!
Hello friends!!! I'm from Brazil and recently my mi 4 band started giving the same problem. at first she only carried up to 99 and yesterday when I went to load noticed that she only went to 95 so this making me nervous, because it only makes 7 months I am using this smartband not want to believe that her life is already beginning to come to an end in less than one year. Today I sent a report on the issue by mi fit as you indicated. now only remains to know if the problem is software or hardware. the good thing is that even with this inconvenience, I can use it for 13 business days until the next charging. never let it discharge completely and always carry it when it arrives in their 13 battery.

Same problem but mine is stuck at 99%

Mine gets stuck at 99%

there was a firmware update in 22/2/2020 did it fix the problem for you ??

Mine is also stuck at 98%. I was able to charge it up the first time to 100% but then it started to go only to 98... Well I guess it's better than to charge only to 50% :silly:

I notice the same thing when I use my external charger. If I connect it to my laptop or directly via wall plug, it gets a full 100 charge. Might want to check that!

Good evening!!! I connected my Mi Band 4 to the USB 3.0 port on my PC. She had 12% battery power and I left it there charging for almost 3 hours and when I went to see it it had only charged up to 98%. Can you only charge it on USB 2.0 ports? How many hours do you leave your smartband charging on your notebook's USB port?

No difference in my case, I tried several chargers (500mA, 1A, 2A) or USB ports (v2, v3). It stayed stuck at 98%. Every now and then it charges to 100%, but it's totally random, most of the times I can't get past 98%.

Solved issue with 99% charge and drop to 84-5% after couple minutes with your guide. Thanks.
Formated Redmi Band 4, put for charging with original USB cable charger and original Xiaomi charger, 5V-2A, 10W for Redmi 4X mobil phone. Worked, charged to 100% and vibrated when reached 100%. I had this issue from 2020 and came with last update.

Slow Charging Speed | Super fast charging not working

My S20+ exynos is charging slowly. Its taking around 1 hr 40 min - 2 hr to charge from 5 to 100. Super fast charging is turned on and when i plug in it states 1 hr 10 min to charge. This seems to be happening from last 4-5 charge cycles. Phone is on latest software(ATCT). Any ideas what to do.

For me it takes 1h5m mostly (15%-100%)
Maybe do you have bad USB cable?

If you are using a cable other than what came with the phone, that is usually the culprit.

Maybe it's only recent or in certain regions? Either way it's clear it has some issues. I've noticed charging issues on ATCT myself

Funny... I've been thinking about *not* using the Samsung 25W charger that came with the phone and use an older sub-10W charger based on the idea that pumping huge current into the battery quickly prematurely shortens its life.
Plenty of articles talk about this.
The cynic in me thinks that manufacturers are pushing the convenience of warp/super/ultra/whatever fast charging knowing full well that users will F**K up their batteries at ever faster rates than before, thus creating a growing captive market for their latest mega-fast charging phones.
All my previous devices had replaceable batteries so I was less concerned with longevity, but having shelled out a not modest sum for the S20 (all my previous phones were superseded eBay items) I really want to get the longest life possible out of it.
I've got it plugged into an HP 1.5A USB charger and Accubattery thinks it should get from 35% to my target 80% in 1h16min, which I think is acceptable. I bought the fast travel charger and fast car charger at the same time, so I'll reserve these for "emergency" recharging and not use them by default.
Anyone else with similar thoughts?

It could be the April update. Mine says "Super fast charging" while I'm plugged into my 25W brick, BUT it only says "Cable charging" if I charge it through my laptop (USB-C) while previously it said "Fast charging". Has anybody experienced the same?

Bro I just found a solution. Not the best but it works. My phone heated like hell even when idle and of course while charging too which resulted in slow charging speed, so what I did is wrap a cold cotton cloth around it while charging to keep it cool, and boom 50% charged in 30 mins. Earlier it took 1 hour for 50% charge.
For the cold cloth, I wet a handkerchief and squeezed the water out, thus ensuring there is no water to deal any damage (although the phone is ip68 rated).
Of course this is not a permanent solution but it works.
Hope it helps :good:

I have the same problem and as pointed out by vanditsadaphale it is related with the temperature of the phone. Mine charges 30% in 30 minutes instead of 50% as advertised and always is > 35.0 degrees Celsius. Also a **** of battery life with screen on time at 5hrs after almost a day of use with 60 hz...

I have the same problem with my S20 snapdragon version ....
Before update:
Super charge and fast charge were fine with same cable and same charger (aftermarket one support 22watt charging)
After update:
With everything in BATTERY SETTING got ticked. It only charges at slowest speed.
Plugged into supercharging port - no response, no charging
Plugged into QC3.0 port - slow charging

Question Problem with charging when completely discharged.

Hello from Ukraine guys!
Last times I have one problem with my phone.
When my phone completely discharged and power off after that I cann't charge it.
I tried different cables and power units without any success.
My phone doesn't charge after 5 or 10 or 30 minutes.
But when I go to recovery mode with battery icon on top right corner my phone charging well and I can see percentages of charge and after 5 minutes with 5% I can power on my phone without any issues. After that my phone charging very well, but if I will forget charge it before it completely discharged I have to go to recovery mode to charge it.
Anyone can help me with this strange problem?
I am using last global OxygenOS 12 C.48 with magisk (root).
Thanks.

If you already tried the MSM tool and clean flashed your device, and the issue is still happening, it seems like there is a weird "HW" issue. So, return the device if you still got a warranty on it.

Sadly i have the same issue. May i ask if you are rooted? Bootloader unlocked?
Since i am on c.48 my phone doesn't turn off when battery is too low (below 1%)
It can go at least 30 minutes in 1 % and this is not the intended functionality.
Battery needs to keep a reservoir to start charging. If it completely drains it damages itself quickly.
Another problem in my end is that c48 doesn't have offline charging (probably because of magisk).
Offline charging is a mode where the phone charges while is off and shows a battery icon.
So in my current state if my phone goes below 1% and i don't manually turn it off, it will forcefully shut down and after i plug it in it will try to turn on and shut down again unable to start the charge.
Only fix is boot fastboot mode (which uses really low power) and plug in for hours until the battery picks up some more voltage and then turn the phone on to charge normally.
Not hardware related. I have this for a while and i still get 4:30 to 5 hours SOT 100 to 1% and fast charge works ok.
Just don't let it go below 2% and shut it off until a fix comes up

Just fyi. This is a really bad practice to do regularly. Battery should not go below 15% often or it will ruin the battery life. See screeshot.
Since you have fast charge, it should be easy to charge it before going to sleep.

@Sergykm since there is no offline charging, try to never let it drain completely

If you already tried the MSM tool and clean flashed your device, and the issue is still happening, it seems like there is a weird "HW" issue. So, return the device if you still got a warranty on it.

I don't want do it and clean all devices's data, because all working fine except charging in "offline mode".

Sadly i have the same issue. May i ask if you are rooted? Bootloader unlocked?
Since i am on c.48 my phone doesn't turn off when battery is too low (below 1%)
It can go at least 30 minutes in 1 % and this is not the intended functionality.

Yes, mate I have unlocked bootloader and magisk and c48. My problem is absolutely the same.
It is not a big problem, but sometimes I forget to charge it before it goes offline.
I'm glad to know this is not only my problem. Hope the problem will be fix in future.
