Hi everyone,
I found a way to improve battery life of our phone. We just charge our phone with usb cable in usb mass-storage mode.
Let it full charge and enjoy strongly battery life. It worked for me and after that you didnt need to charge with cable again just do normal charge with adapter.
Just tested with my phone CM10 A2. Battery drain about 2%(6hrs didnt do anything).
Enjoy!
Try reboot your phone and see your battery drain or not

Lol, no difference at all, you probably just did enough cycles for it to adjust, battery life depends on your usage really.. and this is not a 'fix'.
@Ave666, rebooting will always take your battery down, it will slowly ramp to the correct value again after a few minutes.

Hello all,
There is a drop of true. According to battery's chemistry, it's better to charge with lower amperage. Usual USB port provides 500mAh, ordinary charger 750 to 1000mAh.
Of course, charging via usb takes longer, but battery packs a little more voltage. If you have some app, witch checks battery voltage, you can check it. Read more

Either way, won't 'magically' make a difference from the first charge, that is used to preserve the battery, and not make it magically last longer.. lol.

So you mean to say lower mA battery charger is good for battery health?? I have observed that 1A battery quickly charges battery but also rises temperature of phone as well as battery drian is little bit higher.
I don't think that it makes a real difference. Charging our battery (1650 mAh) with a normal charger at 1A current is fine as it's charing with 0.6C. The charger automatically stops charging when the voltage of your Li-Ion cells have reached the wanted voltage AND the current has gone low (about 5% or a bit less; depends on charger). Much more important is that you don't stress your battery too much, so that the capacity doesn't decease that fast.
Never deep discharge Li-Ion batteries. This kills your battery (Should not happen as phone automatically turns off, but then don't try to turn it on again)
Avoid full full charges. Sounds silly, but voltage related stress is lower which is good for your battery health.
(Thats the reason, why I store my Li-Po batteries for my RC helicopter at 40%-50% charge at the end of summer)
Remember: Bad battery health = low capacity = poor battery life = quickly discharged phone
Charge often to keep your battery at a medium charge level, which is best for your batteries.
Li-Ion batteries dont know the "memory effect". Partly charging and discharging is no harm.
Vishal, mainly, yes. I'm charging usually via USB.

Regards that "unnoticable": Are you saying that in general as you did for the fact before? I'm asking because charge currents greater than 0.85-1C with standard Li-Ion batteries cause a noticable effect.
I have tested some Li-Po batteries with different charge currents, as they where cheaper than the ones I am using for my helicopters. The one that I have charged with 0.75C behaved quite fine, while the one with 1.25 C didn't like that charge currents very much.

nice info thx.
Hello Guys!
I got today a new P3110 and I discacharged it to 2% and I plugged it now to load.
I have seen the charger pushes 2A @ 5V , this is pretty much for a battery of 4Ah, I know from my batteries ( AA AAA and others) that the charging current should be max. 1/3 of the capacity of battery.
So my question is: IS it better to charge it with the Samsung Galaxy S2 charger which provides only 0,[email protected],1V ?
It would last app. 6h to charge it till its full ( can be done over night, hopefully the charger wont melt)....
What do you think about that? Woul it harm to battery(li poly) to do it with small current?
cheers
If the charger seems much then tell me why Samsung made it.

You have got to be kidding me. ITS SO THE TAB CHARGES FASTER. IT WON'T KILL THE BATTERY!!!!
Its because the tab has a much bigger battery 4000mah vs 16xxmah.

Battery life span is a matter of charge cycles 0%-100%-0%. That is 1 cycle and surely batteries don't discharge to 0% not charge fully to 100%
-AFAIK- Even with lithium, Its the heat build up when "fast" charging that shortens any battery life - (same with fast discharging- I would never use those apps that do so) , so I agree with shOne. I have the same model & have noticed the battery does get quite hot when mains charging,( though have never thought to check charging AH).
I would imagine that the only damage you would do with using phone charger would be to the charger, by sucking out more than it can handle, not the battery ! -
-- But why not charge it via a pc usb port - this take a lot longer (so presume much lower AH) than the mains plug in charger - Most usb pc ports are nowadays - permanently live, even when pc off - same with the usb on a modern sky/virgin box. My battery does not get hot, charging this way. I dont know what the charge rate is charging this way ,because both the inbuilt notification & my battery app say "discharging" - (although actually charging)
(I agree that Samsung have provided a quick mains charger, and wouldnt be averse to selling replacement batteries earlier than would otherwise be neccessary, !! (I wouldnt use cheap replacement batteries in any I.T. stuff - I "blew up " a laptop once as a result!!)
I believe that the 2 amp charge is reasonable with the out put of most lithium batteries for this type of device. Since it is a lithium it will not be overcharging or over heating due to sensing, it would be a serious fire hazard... fyi I use a2 amp charger from Wal-Mart and I do not notice my device really heating up...

Agreed. The worst I got was a cheap replacement off a street without a packaging for a dollar. When I plugged it in for a few minutes the battery turned extremely hit and the battery expanded as if it was a puffer fish that took an electric shock

A lot of things I bought from Hong Kong off Ebay actually came from mainland China pfff.....
It's those low quality defects they send you. Mass market goods in china doesn't require quality passes unlike Hong Kong where it's illegal once they get pass customs.

OK, electronics 101, chargers DO NOT PUSH power to a a battery, 2 AMPS is the chargers MAXIMUM OUTPUT, the device plugged to the charger PULLS what it wants (up to a maximum of 2A of current) so it can charge in a reasonable amount of time, you may be able to charge your tablet with a lower output charger but all it would do is take longer to charge (if the charger even had the power output greater then the static draw of the device), which is why most tablets simply CANNOT be charged by the USB 2.0 port on a computer or other small .5 A output chargers. You may very well charge while generating less heat, because of the slower charge cycle using the .7A S2 charger, but at the same time if you try to use the tablet while it's charging on the smaller charger it may very well drop in battery percentage as the smaller charger may not be enough to maintain the current requirements to charge the battery and run the device.
So in short, would charging with the smaller charger harm the battery, NO, but if it is enough to actually charge the device it will take atleast DOUBLE the amount of time to recharge as it would with the regular 2A charger.
First of all . Every night when I go to bed, I like to plug my phone in and charge it while I sleep.
6-7 hrs or so.
Is there a way to stop this fast charge feature , or turn it off. It's a cool addition, however I feel I'm doing more harm leaving it plugged in all night??
Could I just use my old blackberry charger block instead?

Technically , yes you can use any charger you'd like. You don't have to stick with the fast charger. I will though , highlight that the fast charger is optimized for the S6 battery and the battery is optimized for it , so there is no harm in keeping the charger plugged in.
You can't damage the battery if you leave it on all night. All phones have special circuitry to stop charging once the battery is full.
Fast charge works by increasing the voltage, not the current. This is a much safer approach for increasing the power transfer from charger to phone. As it is primarily the amperage that increases thermal output etc.
Although the phone will get warm initially while charging, all phones will. But when the battery reaches full capacity, the battery circuit actually says "okie dokie. I've got what I need now. Let's just trickle charge to keep me full till my boss is ready" and hardly any power will flow through, and the temperature will drop.
Actually makes me wonder about setting up a temp/time monitor while charging to see exactly what happens and when now :3
But as others have said, both charger and battery are optimised for it, and it is plenty safe enough. It's what I do!
There is also nothing stopping you using any other (safe and preferably branded) 5v 1A charger. It will just charge slower. Much like what you are already used to. 3-4 hours instead of 1-1.5ish hours.

Forgive me, I dropped my electrical engineering major, but when we're dealing with direct current, doesn't increasing the voltage by definition increase the current if the resistance doesn't change?
I used the Ampere app to compare the regular charger, from which the phone pulled around a half of an amp, with the fast charger, from which the phone pulled a full amp.

I'm not really sure what you mean by " so should avoid charging the battery is more than power", but battery lifespan in lithium batteries is decreased by FULL discharges and recharges. The best possible routine for making lithium batteries last is to charge early and often. And as genetichazzard pointed out, there is circuitry included that stops the charging (or trickles it) once it reaches full charge.
"Rapid charging", in general, will cost you life in batteries, but that is usually in reference to 4A-6A rapid charging, where this new Samsung charger still does not exceed 2A. I trust their battery engineers. They've one of two things: they have either engineered the batteries and chargers to last in their first sealed body phone, or they are trying to screw us by making a battery/charging system that will force us to pay for a costly battery replacement. They won't stay in business much longer if they go the second route.

I have no idea of the complexities in the technology, or how the phone itself deals with the current from the charger. But I looked at the fast charger that came with my s6 last night, and it is rated like this;
9V 1.67A
5V 2A
The 9V output provides a 15W of power, whereas the the 5V output provides 10W of power.
And after a little bit of reading (can't site my source now as I forgot the website), it is the current that generates heat in the components (such as wires).
So by upping the voltage, the charger is able to transfer more energy to the phone safer than if manufacturers continued to just increase the current.
There will be a smart switching method of some sort within the charger to go from the 5V circuit to the 9V circuit, with a slightly higher resistance to drop the current.
And before I ramble on without making much sense, that is what I have learnt

You are right. Chargers and rechargeable batteries as a whole have been getting "more intelligent" over recent years.
No idea exactly how they do it, I know that a lot of batteries have chips in the that monitor things such as charge capacity and its "health". So I am assuming that they have some form of circuit switch to a higher resistance circuit when the battery is full, so that only a very tiny current can flow, keeping the battery full, without killing it.

Almost always, the circuit is built into the charging device, not the battery. In the case of phone batteries, the phone is the charging device.

Thanks for the link/info. A while after I said all that, I started thinking that it can't be right.
The phone does the regulation, but I'm pretty they (the batteries) do have an integrated chip for health stuff.

Hey guys,
I was looking for some clarification on this topic.
So I heard on a youtube video (can't remember which, for the life of me, I just know it was an S8 video) that Wireless Charging has a better impact on battery in the long run.
They had stated that the battery would continue to hold a better charge over time, where as, if you used wired charging, the amount of charge the battery can hold over time would be much less to when you first got it.
Now I do know that battery gets worse over time, however, I have never heard anything about how wireless charging can increase the longitivtiy of the battery.
Maybe someone on here might have more information on this?
I will try to find that youtube video but if this is the case, then I will definitely need to get a wireless charger.
Regards
Unless this youtuber tested 2 phones for a year, charging one with a cable and another with wireless charging i wouldn't listen to what they're saying.

Yeah I agree. A believe a charge cycle is the same regardless of how it is being charged.
Would never think wired charging puts more stress on battery life.
I think though that with wireless charging once the phone is fully charged the pad cuts out so it won't over charge
With a wired connection when the phone is charged its still consistently trying to charge which can end up damage battering the long term

This is also what I have been wondering. If this is true then I may get a nice wireless pad for charging overnight (maybe the new official samsung "convertible" one but its damn expensive). I would have thought that the phone itself knows when a battery is charged and stops drawing the current from the cable though, so it would make no difference either way if that is true (but perhaps its not?).
But I did hear the exact opposite to op, that wireless charging was worse for the batteries, possibly due to the heat generated. But I don't know how true that is.
True
It's better for the battery because it charges it more slowly than a direct wired connection. There is no more heat buildup than using a wired charger, in fact likely less since the charging rate is lower.
As for the other comment that a wired charger doesn't shut off but keeps charging once the battery is full is patently false. The charging circuits whether wired or wireless are quite intelligent and gradually ramp down the charging current as the battery approaches capacity, ultimately delivering just enough current to keep the phone running. In a closed system the energy has to go somewhere and if the charger didn't do this you'd have 18W of power being dissipated as heat and a serious problem on your hands.

For wireless I believe the heat generated is more, it is about the method of delivering the power, not the speed. The induction used to transfer power wirelessly is obviously going to be far less efficient and will generate more heat to get even a slower transfer rate then getting the power straight down a cable (but if someone knows otherwise then feel free to correct me). But then I guess the slower charging rate might also put less stress on the battery which is probably good.
For the wired, what you are basically saying is that leaving a phone plugged in to a wired charger will not harm it since the current will have been reduced in the same way a car battery charger might reduce it to a "maintenance" mode once it is fully charged. So people are believing the old myths that you can overcharge a phone, which would seem to be impossible (although I do wonder why they keep slapping up notifications saying things like "FULLY CHARGED! UNPLUG CABLE!" as if leaving it plugged in would in some way damage it!).
Just saw this which explains the overcharging possibility (or lack of)

The coils themselves don't generate a significant amount of heat, it's the battery itself that causes the phone to get hot. Slower charging means less heat, which is better for your battery so wireless charging will increase your battery life. As the article notes it is also best to keep your phone above 40% charge, partly because fast chargers slow down significantly after 50% to save the battery. That initial burst from 0-50% is done to save you from a dying battery but it takes its toll.
Also note that the S8/S8+ have new battery technology that provides much improved battery life. They're saying 5% loss of capacity after two years compared to 20% for previous generations.
As a bonus not continuously plugging/unplugging a cable from your USB port will make that last longer too. I hardly ever plug my S7 Edge into a physical cable, and I know quite a few people who have killed their USB ports and can no longer charge and or transfer data from them.

Yeah I am torn at the moment between using cable and getting a wireless charger. I like my stuff charged asap but that's partly because i never leave it plugged in overnight and want it charged before bed (which I now know is not a problem anyway) and partly because i want to be able to unplug it to use it if i get a message or email, which isn't an issue with wireless as I can just pick it up and put it back on there after. I assume taking it off the charging pad and putting it back on will not have any detrimental effects to the battery. I am just trying to weigh up the pros and cons of each. All things considered I am leaning towards wireless, particularly if it isn't worse for the battery (although lets face it the difference in degradation between wireless and wired, is going to be so small it's probably not even noticeable after a couple of years by which time I would have a new phone anyway). I wonder if there is a better wireless charger which will be more future proof than the new convertible samsung one (in case I ditch samsung in future) and still give max speed, I would like one that is tilted so I can see the screen though.
My s5 is 3 years old and has only ever been charged by the massive double width "micro USB" cable which takes some force to get in and out of the socket. Still works perfectly though. Never had any usb port of any kind on any device fail, no idea what these other people are doing to kill them!

Having the dock by my bed is very convenient. Just place it on at night and pick it up during the morning. If I need to grab it for anything I can without getting tangled up in wires and it even sits at the right angle so that the always on display becomes my nightstand clock/alarm clock. Once you've gone wireless you won't go back.

I always turn my phone off at night anyway so I don't get disturbed by some spam message or something (I know I can probably set it up to be silent at certain times, but then why leave it on at all, using the battery for nothing). £70 for that Samsung charger though!! I know there are much cheaper ones but I am not sure they will charge at the same rate, the new samsung one charges faster than any previous wireless charger AFAIK and I would want one where the phone can sit up, and most are just flat. Hmmmm although the do have it for £50 on amazon sold by "fonejoy", still steep though.
This one looks good https://www.amazon.co.uk/CHOETECH-W...=UTF8&qid=1492192247&sr=1-9&keywords=choetech but not sure if itll charge at the same speed as the new samsung one and doesnt use a USB-C connector which probably rules it out. May as well just get the samsung one.
I use the US version of this and it works fine. https://www.amazon.co.uk/d/Mobile-P...d=1492192742&sr=1-5&keywords=rav+power+qc+2.0. The Fast Charging Dock comes with a cable so that should be all you need.

Thats a wall charger? I'm talking about the charging pad itself. I believe the new Samsung one outputs 15w so is faster than any previous ones which are all 10w I think.

There are only two types of charging dock, standard and fast-charge. None of them output 15W to the phone. The expensive Samsung is just a fancy fast-charge dock so it will charge at the same rate as the Seneo and others that support fast-charge. The Samsung fast-charge adapter only provides a maximum output power of 15W (9V @ 1.67A) so it would require 100% transfer efficiency to charge the phone at that power, and in reality it's only about 65% so at most you'll see 10W versus standard Qi charging at around 7W.
All of the Seneo chargers I have coupled with RavPower or Samsung Fast-Charge adapters charge at the same rate (10W to begin with tapering off to 7W above 50% charge).

Ahh ok, I will have to check out a few seneo pads.
If your using fast charging AKA Adaptive charging it shouldn't matter either way. The Fast charging port on the phone, and the wireless charging should go through the phone and the phone should automatically stop all charging going to the battery. This is the reason why if you were to leave your fast charger on all night whether it be Wireless or wired, you can pick your phone up at 99% or 98% instead of 100%. The phone stopped charging, then when it drops to a certain % it starts to charge up again.
As far as which is actually best for strain, it shouldnt matter because afaik to the battery its the all the same. Wireless charging just has some coils almost that send the charge wirelessly, but it still goes to the same place.
This is what I have read from google, so I am no expert on the subject, but it seemed pretty legit, and makes sense to me, a person with a Tech background. If anyone knows better please be my guest.
I'm going with wireless charging pads at home but a magnetic cable for in the car.
Not found a good car holder that has the wireless pad built in so I will stick with my ibolt for a bit longer

There is no correct answer to this question. Battery life is function of many things -
1. Every battery has specified charge cycle. One full charge from min to max is 1 cycle. Two full charge from mid to max is also 1 cycle. So the more you use your device, charge cycles will come to an end more quickly. For example if you use two similar spec phones; first one you use heavily requiring full cycle charge everyday vs second which you use less and requires full charge every alternate day (or to phrase in other way, first is almost completely discharged by evening, second is half discharged). So the theory goes that second phone battery will last double the time than first.
2. Every battery articles you read, you will find recommendation to charge battery in specified current or usually slow charging. Today's battery technology should be immune to this but I still turn fast charging off. It is likely that not all the batteries are immune.
3. Heat is bad for battery. Some wireless chargers heat up. The TYLT VU that I use get uncomfortably warm when I place phone vertically (possibly coils do not align and multiple of them gets activated). Heat build up is there during fast charging too. If you play CPU intensive games and charge at the same time, phone gets warm. All this heat is working negative to the life span of battery.
4. Lithium ion batteries have less chemical stress when they are not fully charged or fully discharged. If you research you will find articles telling one to keep battery between 40% to 90%. Hence I usually do not charge to 100% and if I do, I watch or play games to bring battery level down. Search for best charge level to store lithium ion batteries, I think it is from 45% to 50%. This I guess keeps batteries at the least chemical stress state. So do your maths if you are type who likes to keep battery at 100% charge at all the times.
As you can see there is no straight answer to this question. Battery life is function of all these factors.
Added: I didn't read full article but you can check this link which speaks about impact of heat and leaving battery to full charge state.

Thanks for everyones input on this!
By the way, not sure if it has been mentioned, but this is a pretty cool read:
http://www.androidpolice.com/2017/0...ill-degrade-less-quickly-than-the-galaxy-s7s/
So looks like the S8 won't deteriorate as much over time!
I got the OEM samsung convertible fast charging pad but it doesn't come with a wall plug as I read somewhere (I guess thats just us in the UK getting screwed over yet again). The manual says "Use only Samsung-approved chargers that support fast charging (9v/1.67A, 9v/2A, 12v/2.1A).". So I need a wall plug that will be able to provide the fastest charging speeds from it (which I am guessing is one that does 12v/2.1A??). I dont think all the standard plugs with 2.4a sockets are going to do it right? The "30w" RAVpower one that craigdamey linked says it can do 12v/2A but only for QC3.0 (which I obviously wont get since its just being plugged straight into the charging pad), otherwise its 5v/2.4a. Not sure what one to get now. Theres an Anker 24w one but that says 2.4a per port (I know little about electrics and how these things work!).
So I got an adapter to use a wired headset with my phone, it's one of those that allows for both headphone use and charging, though you need to plug in both, but I notice after I tested them out, my estimated battery drain declined all the way down to 9 hours remaining from a charge of 89 percent.
It used to be anywhere from 23 hours to a whole day, did I just break my battery? I'm not in a position where i can replace it if it goes wrong, especially since I just got this a month ago.
Checked it and it doesn't show any apps sucking power, I also disabled various bloatwares to make sure it would run smoothly.
I only had this phone since December and I made sure to charge it when needed, keeping it at around 40-80% charge as much as I could.
Phone is a OnePlus 8 5G, battery drain before was about a whole day before I needed to charge unless I were watching videos, and even with that it still lasted a good while.
It's not a good idea to use and charge the phone as it disrupts the charging curve*. If the screen is off and the device power usage is minimal like listening to music on bt does not interfere with normal charging, at least on my 10+.
Give the phone it's quiet time to charge.
Limit charges to 80% preferable 70% and discharges to 30% preferably 40% to maximize battery life.
Avoid going under 20% or full charges to 100% as it needlessly stresses the battery.
Li's love short, frequent midrange usage like from 40-65%
Li's hate high heat (>100°F) and high cell voltages ie >90% charge.
Avoid charging below 72°F as it can cause Li plating which will permanently degrade it.
Never attempt to charge if below 32°F.
*if you're drawing power whilst charging the device you can not gauge its actual battery capacity. It will charge much slower or maybe not at all.
Stop that you!
Take a 10 or 15 minute break and let get it take a charge.

I don't use it when it's charging, it's a OnePlus with warp charging so I let it sit until it's either full or usually at around the 80 range.
It seemed fine until I tried using this headset adapter, I don't know if these can break the battery in any way so i don't know if just using this messed something up.

If you have fast charging just use the standard fast charging cable to charge it not the daul use one.
The latter may not be recognized by the phone for fast charging, if so it will default to slow charging.

Warp Charging works yeah, I'm returning the headset cable and replacing it, since i don't know if it messed my system up, and aside from that it's clunky to use.

It was this thing.
do you think my battery is just messed up at this point or is it fine? Battery estimates used to show 23 hours to a whole day, but now it's down to 9 hours so I don't know if that messed up my battery somehow.
I doubt it messed up the battery especially if it's been only a week or whatever.
More than likely it's a misbehaving apk(s) causing the drain.
If your battery's rated capacity is 1000 mAh and you're only getting 400 mAh out of it, then you have a battery issue. How long it can run doesn't reflect battery condition unless the load is the same as before. So you need to scrutinize it further before making the assumption the battery has deteriorated.
I use two overlay apks (Accubattery is one) that let me see total current draw in near real time. I'm running Pie and doubt these will run in Q.
At idle my draw is an average of 150 ma or so with lows going down to 79 ma. If I see it averaging 300 ma with spikes going to 800 ma at idle I go looking for the cause.
