I put my phone to charge around 8 or 9 pm. Just unplugged around 3am and its at 97%.I used oem charger. That should be more than enough time to fully charge. What could cause this? Oem battery as well.
???
I've noticed that it backs off it's charging speed for the last 5% or so. I have a hardware dongle that measures current passing through USB cable ( powerpractical.com ) which confirms that it's drawing much less current when in the 90+% range. I suspect this is being done intentionally to reduce wear on the battery.

The first time I got the phone, I used up the battery. Then I recharged it for only 2 and a half hour to get from 1% to 100%. There might be some problem with your phone. Did you notice any apps used during that time? Probably because something kept the screen on during charging.....
Hm, yeah, my phone charged fully within ~3 hrs from 40% today (though the charging rate does slow dramatically at the end, falling from 5W (according to hardware meter) with 1400 ma charge rate reported in software, to 3W and 900ma at 90% and 2W and 450ma after 95%
I remember seeing the last few percent take a lot longer than that in the past, and coming back after many hours of charging to see it at 98%, rather than 100%. Strange.

Hello everyone. I have this phone for a week right now and I'm really impressed how brilliant it is! I love it. But there are some questions I want to ask you and one of it is:
What is your average charging time from ~0% to absolutely full 100%? In my case it's about 3 or even 4 hours of constant charging. Even when on 100%, my widget (Battery life by Curve fish) doesn't show it's fully charged - still I have to leave my phone connected and after 30/40 minutes it says "full" and I can disconnect it. It's pretty strange because the charger is meant to have 1,5A output which is VERY BIG current in comparison with Xperia PLAY's charger (850mA). And many reviews of this phone say that the full charging cycle takes about 1h 30min from 0 to 100... What do you think?

Are you using it while charging 3-4 hours, if you are using it, it's charged and discharged at the same time?
But from what I know - thermal throttling is the cause again. Especially if you're using it.
Maybe it charges 1,5Ah for the first 15 - 30 minutes, but then the current goes down, because of the temperature.
Somewhere between 80-100% it is normal, that it takes longer. The charging current is as low as high is the battery charging state.
I was under the impression the charging capabilities of this phone were insane? My note 4 is charging very slow even with the phone off. Ive toggled the Fast Charge on and off (battery page in settings) and regardless of what i chose its very slow. I think my Note 3 charged faster than this. Is something wrong with my charger or my phone? Should i echange it for another?
Exchange it. With the included charger mine charges in about an hour.

The way fast charge works is with wall adapter and cable that came with phone and screen off. Another way is phone off. Takes a bit over an hour when phone dead
NOTE 4
Looks like I'll exhange it then, cause with the phone off, it took about an hour to go from 25% to 38%. Its strange cause my note 3 was usable while using GPS, and phone connected to car charger, not even a 2.1amp one and it would charge quickly. Note 4, actually went from 38% to 52% in about 3 and a half hours the same way
Mine is the opposite, charges fast and and drains fast. When I unplug it will go from 100% to 95% in 5 minutes with no use and screen off. I tried several battery app with no success to fix the problem.

Fast charge will only work screen off. If u using GPS then phone is awake and u get slow charge
Also make sure fast charge is clicked on.
NOTE 4
Did you take off the plastic stickers from the charger? Mine started fast charging after I did that. I think it was covering part of the connection somewhere.
I hope u connected to ac and not USB check battery in settings make sure it says charging ad and not charging usb
Yes mine says it is charging via AC. I havent removed the plastic from the charger, ill try it. The weird part is, last night i had 5 percent battery. At around 2:30 i turned off the phone and connected to the charger. I wake up around 9:30, a whole 7 hours later, and the phone only charged up to 89%. It takes 7 hours to not even charge full percent? Is that normal? Granted, if i turned off the phone or even had it on, my Note 3 charged within 2 hours or less even from dead. So i should just exhange the phone right?

NOTE 4
Hey guys,
I haven't used my Galaxy Tab S2 in a while now. When I plugged it in it was at 0%. I used "a" (possibly not original that came with box) OEM 2.0A Samsung Charger + Note 5/Samsung Official Cable to charge my tablet. It has only gone up by 5% in the past 30 minutes.
Also when it was at 0% it said it'd take 7hr 12min to fully charge.
Is this normal when the tablet has not been used in a long time, or am I possibly looking at a bad charger/cable as the charger and cable charge my Note 5 just fine at the normal (non-fast charge) speed where it charges my phone fully in just over 1hr 30 min.
If someone could help me out to resolve this I'd be grateful.
Thanks! :laugh:
Don't think the charger and cable are faulty as they work on your mobile. Generally whenever I charge my Samsung galaxy tab s2 using a different charger it shows a notification if the charger plugged in is slow. If it didn't show this I don't see why it would take so long other than the charger your using has a lower output causing it to take a lot longer than usual to charge.
Every android device I have will sometimes not charge fast enough - it doesn't matter what charger I'm using. If I catch that the charge is slow I just unplug it and replug it a it'll be normal again. I think the "smart charge" goes crazy sometimes.
I had the same problem on the tab s2 8''. It was because the motherboard broke. They fixed it under warranty.
When I had this problem I couldn't attach any external device (usb, playstation controller) through USB. Try if you can
I don't have the original charger anymore to compare on my 9.7. I use anker potable batteries to be free of wall sockets. It isn't 2.0. In battery monitor widget, really good app, shows charge anywhere from 1200-1600mA 20% per hour while in use during charging. 5 hours total. I think with screen off I get 30%. I get 10 hours of screen on time zero loss with it off over night. Using 5.1
It could be the motherboard. I know with laptops charging starts to mess up a few weeks before it no longer works at. The connection between the USB and board weakens over time/use.

Sounds normal. The big Lion batteries in these devices are just weird at time. Running one down to 0 is a good way to kill the battery permanently. Let it charge slowly and then keep it above 20-30% from now on. Should improve over time.
I think its a myth you shouldn't let the battery get low. As long as the battery itself says I'm at zero at the correct voltage then zero is perfectly fine. I'm not an expert here but at 5% battery I'm at 3.6v and will turn off in a few minutes after that. I think batteries are manufactured to safely go down to 3.2 before saying no more. Need to charge.
Is it normal behavior that supercharge "slows down" as it gets closer to full charge?
I am asking because i have noticed that my 1 month old P20 Pro charges slower even though it displays "supercharging" on the display? Maybe i am imagining things, because the battery was at 89% when i plugged it in.
I have used Ampere to monitor the charging current ant it stayed around 750mA during most of the charge and dropped to 450mA at the end.

As far as I know, the low battery power of mobile phones is usually due to the fast charging speed. When the charging rate reaches more than 80%, the battery power is close to the full. In order to ensure the safety of use and extend the battery life, when the battery is rapidly charged, the charging current output by the charger will gradually decrease and the charging speed will slow down until it is fully charged. This feeling is normal for you. How long does it take you to charge from 0% to 100%?
Yes - This is generally a safety measure for the battery.
How long does it take from 0% to 50% and as far as I am aware it slows down from 60%
Thanks for your replies bobo and mulkman.
It is reassuring that my device is ok and (hopefully) I am only imagining things
I haven't had the chance to charge from <50% to 100% but I will leave the phone to go below 50% over the next few days and charge it up to 100% and post the result.
Finally my phone discharged enough so i could do some charging.
Started at 44%
Total charge time 66 minutes to 100%.
Supercharge indicated 100% of time.
Meassured approx. every 10 mins (6 time points)

Hi!
Check whether the phone and the power adapter are connected properly. And you should use box accessories (original) charger.

Connection is as good as it gets and I use the charger and cable supplied in the box with phone.
Is ~40% - 100% in ~1 hour normal charge speed? (Phone is on, screen off)

Hi! Was your mobile data on while charging? Because it takes more time when mobile data is on or mobile is heated up.

Everything was on, but the phone was on WiFi. Temperature of the battery did increase to 32 degrees centigrade (checked in Ampere). The phone is in a original Huawei smart case, which may increase the temperature.
It's probably about right. It slows down at the top. Attaching a couple of charging sessions for comparison. You can see that the percentage per minute decreases when the battery reaches the higher levels of charge. At the rate of the first picture/occasion it would charge the battery in half an hour. But that's not the case since it slows down a lot.

It seems that my phone is behaving normally :fingers-crossed:
BTW I did test it with a new charger/cable and got the same results.

Good to hear.
Is your phone in one of those TPU case and if so remove it before charging your device.
The charging speed is dependent on the current battery temp so it may throttle if your device gets too hot

My phone is in an original Huawei flip-case. It is made of PU-like plastic/rubber material and must insulate quite a bit.

Yes most definitely.
Have you ever noticed that the phone gets warm during the first 0-70% of its charging cycle.
Towards the end the phone enters trickle charge mode to protect the battery

I haven't noticed before. I usually have my phone on the table while charging and i dont pick it up. But when monitoring with Ampere I noticed that the temperature went up.
How long it is supposed to take to fully charge it with 25W charger?
Are the first times you charge it slower to reach full charge?
The time will vary. Battery capacity, discharge state at start of charge and the battery temperature throughout the charge cycle.
Charging from 0-100% stresses the battery (especially with fast charging) and shouldn't be commonly practiced.
Battery start charge temperature should be at least 72F, 82F is ideal. Cool it if it exceeds 99F while charging. Charging is a electrochemical reaction and some heat is needed to avoid Li plating.
Never attempt to charge an Li near freezing temperatures
Li's thrive on frequent partial charge cycling. 40-80% is a good range.
Avoid going below 20% or over 90% except occasionally for best lifespan.
High temperatures and high cell voltage are Li's biggest lifespan risks. Avoid running the phone when the battery is hot (>102F) or provide cooling. Keep it out of direct sunlight especially when charging.
Store Li's in a cool, dry place with a 50-70%charge, not 100%!
GSMArena:
" We tested the Galaxy A33 with the said 25W USB-C Samsung charger, and it replenished 50% of the battery in half an hour.
A full charge took 1 hour and 15 minutes, and in fact, that was the cited expected time to full charge by the software as well. "
Fast charging will yield roughly 2%@minute from 0-80% if battery doesn't go into over temperature ramp down. Time it to get the nominal rate for that device ie how many seconds per 1% when fast charging in the 40-70% range, probably 30-40 seconds per minute when new. As it's capacity from degradation drops so will this rate.
Charge rate will ramp down at around 80%, then again at about 90% to protect the battery.
Temperature is the biggest variable.
If the battery is below about 60F fast charging will not engage for that charge cycle in order to protect the battery.
Fast charging rate not clear cut as the power controller optimizes charge rate per conditions and will reduce charge rate if they're not in the optimum range.
Constant erratic fast charging cycles with a known good brick/cable indicates a battery failure.
Any battery swelling is a failure, stop charge and replace it asap. It can damage or destroy the phone
Replace the battery when it reaches 80% of its initial capacity, the end of its useful service life. At that point it's considered degraded, degraded Li's are far more likely to fail. An Li can fail at any time... it can happen fast. Cataclysmic failures however are rare.
My new A33 came a couple of days ago with about 30% charge. I used it a bit lightly with the intention of depleting it(so I can have it full when I root it), I haven't yet installed the SIM, and when it was about 15% I got tired so I downloaded an app "Generic Battery Drainer" to deplet it quicker until it reached 0% and turned off, then I charged it to 100% with the charger I purchased which came today(an OEM one)
I didn't know that you should never deplete the battery to 0% and also did not know that the battery should not be charged to 100%
I obviously also didn't know the dangers of high temperatures, because the drainer app took the cell phone to about 104ºF
What prompted me to post my question actually was that from 0% to 100% charge it took about 3 hours. So I'm wondering if maybe I should check if the OEM 25W charger that I got does not charge fast as advertised?

You should fully charge a new battery before using. Are you using the cable that came with the brick? Is the wall socket wired correctly?
3 hours is far too long for fast charging.
Observe while charging to see if it's fast charging be % per minute.
The display must be off or it will skew the charge rate badly. Start and maintain it in temperature parameters described when charging.
If it drops out of fast charging because of temperature it will likely not reengage unless the cycle is manually started again ie unplug/ plug back in. Don't try to fast charge a hot (>98F) battery, it won't work. Cool the battery down and use cooling while charging. A damp microfiber cloth and/or fan work well.
Briefly turning on the display will not break the fast charging, it will resume once you turn off the display. Low current drain apps like Poweramp/bt can be used while fast charging but not high current drain ones.

Should be good to go.
When you get to 40%, try again... it's probably ok.
Try using a wall socket on a different breaker. Line voltage fluctuations won't effect this brick however neutral/ground fault might. Avoid using on a circuit with large induction motors on it ie microwave ovens, friges and A/C
