Isn't Fast Charging Bad For The Battery?
That would depend on the battery's C rating. Charging at higher rates doesn't necessarily cause damage. There are plenty of articles on charging lithium ion/poly cells out there.
In my previous S7 Edge , the battery lost plenty of juice in just one year of usage ( i was using wireless charging only). Then i sent it to samsung warranty and they replace battery. Tried to find something about if could be the wireless charging that damaged the battery and found none that supported that theory.
Now, with the S8, i´m using the provided charger and cable only (Just to be safe).

Wireless is different due to the losses in the induction, creating heat, which does have some affect. But there are a lot of variables as to why your battery performance may have degraded.

Right... it seems every day someone thinks they know more than engineers in that field, battery is getting hot so it must be bad. Yet every year qualcomm and others improve quick charging for even faster charging, so unless someone actually knows something these threads should just stop.

Why would you assume its bad for the battery in the first place? Just because it gets hot? The cpu also gets hot when gaming so i should stop gaming? Recording 4k videos also heats up the phone so i should stop recording 4k video's? Constantly downloading will probably heat up the modem too so i should stop downloading? If something is built into the phone why would you assume its bad for the phone?

What gets hot? Who said anything about hot?
Hey, don't take it badly, he is just asking. I remember old batteries (for example ni-mh) if you charge it at a high current they use to live less than if you charged them at a slow one (i remember using rechargable batteries of this time for my wii control and i could test it with how long they lasted).
I think the new Li-ion (or better) batteries nowadays don't suffer from this, so you should be safe about them. They have a natural capacity loss thats isnt affected about the rest of the things. You should anyway check for faulty chargers or your battery life, remember all the test samsung makes are with their original hardware.
Regards!

This is someone not knowing what they're taking about trying to talk down on someone else.
Anyways heat has always been detrimental to battery health which is why samsung fast wireless chargers have fans built in to keep the heat low. Along with this the phone will prevent charging if it passes a certain heat threshold I believe 40c iirc and also the phone uses adaptive charging to prevent over heating of the phone with the included fast charger and charging circuit design. As long as the phone continues to regulate the charge coming into the phone fast charging shouldn't hurt. Of course with fast charging you go through battery cycles faster but this is just because you can charge it a lot more times than with regular charging.
My personal experience:
- 2 years of fast charging = battery drain between 100 and 90 very much noticable
- charging over night causes more damage than fast charging

Hello dear members
I'd like to ask if an everyday charge will harm my battery.
It's my first week with my phone, and I can't keep my hands off it
As a result, battery runs out every day!! So I charge it...
Will something happen to the battery?
thanks in advance
This phone has a litium ion battery. They don't have a memory effect but in the first time they need some time to become the full potential. So it doesn't matter if you charge the phone every day.
Sent from my GT-I9100 using XDA App
Thank you so much!!!!
It's a relief
To maintain better battery life it might be a good idea to make sure that u dont fully drain the battery
That shouldn't be a problem the most battery's should have electronic inside to prevent this but I can't guarantee it. You can read also the Wikipedia article about lithium ion batteries it's quite interesting.

It is better for you to charge daily and often when the battery still has charge and not leave it until the battery is totally flat.
Thanks so much everyone Point taken
I'll never let it fall under 10%.
Well, Battery is average. If it weren't for the 2.3.3 bug, it would rock! In order for it to be normal, I keep ****ting Services.(under Services menu) like Voice talk, SocialHub(which drains a lot of battery) etc
Anyways, thanks to everyone

Isn't it actually opposite, I mean somewhere I heard that if a Full charge is given after a Full drain then the battery gets conditioned (optimized I think), can't remember the source but I do remember the fact.

I'm glad this thread exists. I'm so used to running a battery down to the minimum before charging it that I probably would have been in that habit for my SGS2. I'd actually come here to ask the same question now I've been through my first four or five "full" -> "red" -> "charge to full while off" cycles.
Is it confirmed both from the SGS2 & LION technology point of view to now keep it charged up, even if using only half/quarter charges etc to do so?
My battery is giving me around 40 hours a time so not too bad but I'd like to keep it running as well as I can.......

Nope. Li-ion batteries these days prefer constant top-ups and full drain actually kills it faster. Totally opposite of what people have been taught over years of NiCD battery use that I've got friends who absolutely refuse to charge their iPhones unless it's at 10% or less. Their loss.

No that's only good to do once in a while. Full discharges daily put stress on the cells and wear out li ion batteries quicker.

Yes it's common for all lithium ion batteries to charge as often as possible. Its true for all phones on the market today and quite a lot of discussion on this is all around the web.
Also a replacement stock battery for any cell phone today is around 20 dollars, so really you can't do much wrong since its so cheap to buy a new OEM battery replacement.
Thanks for the replies. I think this will catch a few people out so hope the thread doesn't get missed amongst all the other battery ones!
Looks like I'd better change my charging habits!
i just got this phone a few days ago. i love it. nothing wrong with it.
super fast and everything. im on 2.3.6. no issues. my battery lasts 12 hours easy. and actually up to 26 hours so far.
i dont even feel the need for a custom rom. at least not for now.
but one thing that makes me mad is how slow the phone charges, anyone know why this is ? it's kinda frustrating lol
any way to change this ?
also....i kinda hate that there is no camera button on the actual phone. oh well.
*Edited*
well i dont like to charge unless my battery is on red. so that conflicts, its not always red when i go to sleep. but thanks i'll check it out.
and i dont want to unlock to camera. it's easier to take photos with a button is what im saying

If I remember correctly waiting till the battery is completely depleted is not a good thing for our batteries.
i never said completely depleted though.
and yea ive read so many reviews to not do that, and reviews that say you should... and reviews to charge it this much and that much and blah blah. may be a new phone, but none of this is new to me.
Charge current is hardware limited from what I've read. Or atleast for the time being. If your using the phone while charging it'll be significantly slower. Also using wallplug makes a difference. If you've got stuff running while charging try throttling down the CPU while charging.
Other than that I think our phone is limited to 650mah to charge. So 1650/650 is about 2.5 hours with perfect efficiency. Now take into account the power being drawn and how the chargers for li batteries work, that's about 3-4 hrs to be expected.
And don't run li batteries all the way down on a regular basis, its not good. I'm not positive on li ion batteries, but with lipo you generally want to use about %80 of rated capacity to prolong life and power of the cell.
400 mA on USB, 650 on a wall charger, CPU/screen usage counts against these limits - no way to change this
Forgot where I read it. Could be wrong too.
Slow charging for this phone was samsungs way of keeping our phones battery in shape. Hopefully prolonging the life of it. I noticed my 3GS lose about 20% of its full capacity in a couple years. Only time will tell?
Siyah has an option to upping the charging mA I believe.

i dont use it when it charges and yea it does take about 4 hours to charge.
coming from a crappy xperia x10 which took about 2 hours to charge from 0 to 100
but this phone is 10 times better even without a custom rom so i can deal.
thank you guys for ur knowledge.

He removed it because it turned out not to work. (If it's still there I'm surprised - it should be completely gone.)
It turns out the I9100 has the same limitation as the I777 - charging is handled not by the MAX8997, but by a MAX8922.

If you are on Entropy's DD kernel you should divide that number by 2.85
Battery charge current monitoring (CurrentWidget) support - only reports charge current and not discharge, and reports a value 2.85 times the actual current. Use CurrentWidget's "operation on value" to divide by 2.85.

My phone has 50% battery left. I plug the cable into my laptop to charge over USB. Then I play some games at the same time. The battery level comes up slowly.
So is it good to do that? Or we should do one at a time: charge or use phone.
I have always done it that way and ive had android ever since it first came out. Nothing should go wrong, at least not for me.

Wont harm anything
it doesn't matter if affects to the battery or not, you will trade your phone for another new one before the battery gets damaged
The only issue is that the phone will heat up like crazy so...
If you're overclocked or it's a very hot day, please avoid doing this, otherwise you may damage your phone.

Using while charging overheats the battery and the mobile itself.
Heat is the biggest enemy of batteries (wrt. longetivity), so yes it does reduce battery life. Having said that, most of us upgrade phones in less than 2 years, so it wouldn't be as much of a problem.
But overheating is not good for rest of the phone hardware.

I really doubt that. If the phone or battery were overheating, you wouldn't be able to touch it.
Maybe it reduces battery life, but that can't be much, since the battery gets hot whether it's being charged or not.

Using it while charging is fine. Mine charges at about 30-35*C, gaming on top its up to max 41/42. Thats well within limits and its going to have negligible effects on the battery pack.

This phone with and with original charger, and AFTER teh update from Gingerbread to ICS/JB is charging as per specs. On Gingerbread there was a flaw that permitted to charge it upto 900-1000 mA but the phone was rather hot, I recall charging mine in an hour and a half or 15-20 minutes more, from 2-3% to 100% back when phone had GingerBread.

You can use 2.1A output chargers too, it is simply not going to draw all that but you might get the better on the go recharging while you're using the phone with heavy apps. Just think of the dual car chargers - they have both 1A (phone) and 2.1A (tablet) output. SatNav on 1A is zeroing or still draining your phone battery, while 2A can slowly charge it on the go.
You just give it a needed juice and if the discharge is so greater then recharge, there's not much you can do about it.
Call it a flaw, but Samsung did it cause of longevity of their batteries and li-ion technology.
That is why I indicated iCrap and BB - their fast charge is provoking rather fast discharge too cause the battery will not hold it. I have colleagues with BB who're charging in an hour but get their phones depleted in 3 hours of usage... I wouldn't want that from my S2 for sure. :good:

It doesn't matter what the output current of the charger is... the phone will only draw 650mA.
The charger I got with my S2 delivers 1A but my phone only draws 650mA. Actually the hardware doesn't support it.
IMO, 3hrs is pretty fast for a full charge.
Edit: Just noticed that Fevves already mentioned all that...

Some kernels have the Option to change the charge rate but even at 650mA the phone will get very hot if you are doing something on it while charging

Hi,
So I've been using an app called Battery Charge Limit from the Play Store (https://play.google.com/store/apps/details?id=com.slash.batterychargelimit) to limit my battery charging upto 80% using root access. This was to increase the longevity of the battery.
Worked fine on Oreo, but now for some reason it doesn't seem to stop the battery charging at 80% on Pie. I was wondering if anyone else has encountered this issue and has found a fix/workaround?
I know its probably better just to ask the app developers, but I was just wondering if anyone else is having this issue as I also have access to an S7 Edge on OneUI Pie and it doesn't seem to have any issues.
Thanks

I do not see any sense in such charging settings, the V30 with 100% notification is still charging for 30 minutes with low current and then only reaches a physical 100% battery which is to save the battery. As the program disconnects charging at 80% it will be physical about 70% = 2/3 for battery use. You probably don't discharge the battery less than 30% because you will "damage it". Then use 1/3 charging it 3 times at the same time as I do ... So think about whether after these 4 years you won't have a more dead battery than I, kids, I charge 15> 100%.
Yes, the answer is simple, charge up to 100% and disconnect immediately, just like LG limits charging to physical 95% so that the battery does not lose capacity.

I do not see any sense in such charging settings, the V30 with 100% notification is still charging for 30 minutes with low current and then only reaches a physical 100% battery which is to save the battery. As the program disconnects charging at 80% it will be physical about 70% = 2/3 for battery use. You probably don't discharge the battery less than 30% because you will "damage it". Then use 1/3 charging it 3 times at the same time as I do ... So think about whether after these 4 years you won't have a more dead battery than I, kids, I charge 15> 100%.

Fair enough. I simply limit it to 80% as from what I understand the majority of battery wear happens between 80-100%, even if it is charging at a much lower voltage and current.
Even if the phone doesn't show the true values of physical charge, a physical 70% charge is enough to get me through the day and I don't worry too much about how much battery I drain so only put the phone back to charge when it's at ~5%. So only charge the phone once a day.
Even if it may/may not make a difference to longevity it's worth a shot. At best it'll improve the lifespan of the battery, at worst it'll do nothing with normal degradation.
Maybe in a year or so when 80% charge can't get me through the day I might drop the limit. For now it seems worth a try.

Just for your information, deep discharges are also not very good for Lion batteries. Discharging to 5% regularly is as bad, if not worse, than charging to 100%. The optimal is to always keep the battery level between 40%-80%.
I am not so sure if that will make any visible real world difference since most people don't tend to keep their phones for too long. And since that limits the effective battery capacity too much, I would suggest that you don't worry too much about charging/discharging too much.

Hi,
So I've been using an app called Battery Charge Limit from the Play Store (https://play.google.com/store/apps/details?id=com.slash.batterychargelimit) to limit my battery charging upto 80% using root access. This was to increase the longevity of the battery.
Worked fine on Oreo, but now for some reason it doesn't seem to stop the battery charging at 80% on Pie. I was wondering if anyone else has encountered this issue and has found a fix/workaround?
I know its probably better just to ask the app developers, but I was just wondering if anyone else is having this issue as I also have access to an S7 Edge on OneUI Pie and it doesn't seem to have any issues.
Thanks

To answer your original question, the same feature works as intended on a different app (AccuBattery) on my phone, stock unrooted open EU H93030b. So it looks like your problem is not the OS but the app.

Yeah I am aware that discharging to 5% can be just as bad for the battery. But even if I charged to 100% I would still use the phone till there was only 5% left. So I just thought might as well try to limit the charging and see if it makes a difference on the long run, since 80% gets me through a the day anyway.

Thanks for your help! I did try out Accubattery and yes it detects when the battery is at 80%. Just wish it could set limits with root access as well.
In any case, I seem to have found a solution now. There's a Magisk module called Advanced Charging Control (ACC). This seems to work well and limits charging to 80%. It also has a companion app that you can use to set your own preferences and limits.
I've linked the relevant thread below, might be useful to others.

Your doing more worse then good letting the phone go to 5%. That app will not do ANYTHING for you.
Sent from my LG-H932 using XDA Labs
I find ACC works well at stopping the chargeing at a certain % level.
Hoiwever then while still connected to usb it draws power from the battery - not good.
Battery charge Limit on Oreo stoped charging and used then power from usbb onwards while still connected.
I wonder how ACC stops the charging on Pie, i.e. with what control file. Has anyone got an idea?
I foudn out that the switch is /sys/devices/platform/lge-unified-nodes/charging_enabled. This starts/stops the chargi8ng.
Unfortunately, on Pie, when this is set to disabled from then on power ist not drawn from the charger but from the battery.
Is there any other switch / wax to prevent this?
Ich want charging to be stopped and from then on power to be taken from the charger while connected to it.
Here are the paths to the CTRL files that I've found to work with the two ROMs that I've used recently:
Havoc-OS wired and wireless: /sys/devices/platform/lge-unified-nodes/charging_enable (no 'd' on the end, unlike what bladecgn gave)
Lineage OS wired: /sys/class/power_supply/battery/charging_enabled
Lineage OS wireless: /sys/class/power_supply/dc-wireless/charging_enabled
One quirk that I've noticed is that, on wireless, the app ignores the "Recharge below" setting and starts recharging as soon as the percentage drops just 1% below the max (ex. if the max is 80% and the charge drops to 79%, it'll immediately recharge back to 80%, even if "Recharge below" is set at 76%).
For the record, the ROM that I'm using is LineageOS 17.1, so the app definitely still works on Android 10.

Were you able to figure out how to use only power from the charger instead of the battery, @bladecgn?

Stock Pie doesn't have the /sys/class/power_supply/battery/charging_enabled file, but it does have /sys/class/power_supply/battery/battery_charging_enabled. Would that work?

I don't know. You'll just have to try. It's a process of trial and error to find which path works with which ROMs.
