[Q] Slowing down battery deterioration - Galaxy S6 Edge Q&A, Help & Troubleshooting

Yes, I know that there is a battery life thread but this is question is not about SOT and what apps eat up battery. I'm just trying to figure out how to extend the battery's lifespan
Battery life on phones inevitably get worse over time. With the S6 being sealed so tight in one piece, it is not going to be easy to just pop in a fresh battery after a year or so when your battery starts lasting you just half a day.
I've read contradicting info on whether or not you should be using your battery right down to 0% to "break in" a new battery. One of my friends constantly drains his battery down to 0 before charging it, while I've read that this is bad for batteries from other places. Another thing I hear people doing is unplugging their phones from the charger soon as it reaches 100%, does this actually do anything? I just want some tips from people who would know how to get the most out of a battery over time.

Batteries are pretty smart these days, so they'll not over charge unless very defective. LI batteries do not need to be drained first... the old NiCad ones did IIRC. The life of a LI battery is going to be measured in full charging cycles, so partial charging makes no difference to the overall life of the battery vs draining completely before charging.
Coming from an HTC One, removable battery really want an issue for me. Although I'd certainly prefer it.

Like bjhill said, li-ion and li-polymer batteries these days should wash away any concern you have with the battery's lifespan.
Some people say occasionally you should drain your battery below 20% and charge it all the way to full without interruption (maybe once a month). Other than that there's jack all to do.
You don't need a new battery after a year, unless you did something stupid.

Just make sure that the phone doesnt overheat while charging. Thats the main reason for bloated batteries.

Conditioning new battery

Ya... I just got the gsii this morning and I'm very happy with it. Just curious as to do I need to charge the battery for 8h for 3 days or not. Thanks

Charge the battery, run it down to zero, charge to full, repeat for the first dozen ours so times, battery life has been improving in each cycle and I also recommend you do the same

But isn't flattening Lithium Ion batteries bad for them? If you search the internet it often says not to over discharge as well as under charging them also increasing their life span. The older NiMh and NiCd batteries benefited from full discharge and recharge.

If there's one way to send your battery to an early grave, this is it.
Modern batteries are limited by their number of discharge/recharge cycles. Letting the battery drop to 80% and then recharging is the same as letting it drop to 20%.
However, allowing the capacity to drop to zero is a stupid thing to do, since this permanently damages the battery. The battery has its own controller which goes some way towards protecting it, but it's a trade-off between shortening the lifetime and the actually runtime you can get from the battery.
So, to summarise: you're fine letting the battery drop to 10-20% before recharging. Do not allow it to fall below this too often, as you'll shorten the lifespan.

Yes it is 'bad' for Li-on batteries to be run down to zero. Ignore any posts you see saying otherwise.
Just charge it and use it. When possible, top up charge. Li-on batteries do not have memories and do not need to be 'conditioned'.

Hmm, my bad, my Apologies, seems there's some way to go yet for me, I assumed this was the case as I had horrid life out straight out of the box, these discharge cycles helped tremendously, though with that being said I tend to not leave it below 15% now before I charge.
Oh well, live and learn.
Never discharge the battery to less then 10-15% if possible.
Aww crap I discharged it to zero last night. I thought out make sense cause back when I used the nexus one, there was this method of conditioning battery by discharging the battery. Ah well thanks guys

Won't hurt that much. Contrary to what people say li-ion has limit on amount of recharge applied from whatever level it was applied. Also the phone cuts off before dangerous low levels are reached. However frequently doing this should be avoided.
The biggest danger is leaving phone in discharged state for long period of time as the background discharge (e.g. Power on off button, clock, etc.) will flatten the battery, without the protection circuits and completely ruin it; charging while hot (above 50 to 60 c) will also send battery to an early grave.

[Q] When should I charge my phone?

To get the best battery life, when should I charge my phone? When the phone almost runs out of juice, or whenever I can (below 80%) ? Please help!
Deep discharges are bad, but so is spending lots of time at maximum charge.
I'd consider charging around when you hit 80% if it's convenient, but if you're expecting to be on battery for a while soon, top off whenever you want.
Discharging to 5-15% is bad for your battery longterm.
So to get the best battery, I should charge when it is $80 right?

There's no hard fast rule about 'exactly' when you should recharge it. Simply try and keep the phone from running < 20% a lot and never keep it always charged at 100%. If you get in the habit of charging in the 30-80% range, that would be best.
Basically throw out the old mentality of always using it as much as possible before recharging as lithium batteries simply don't work like the old nicad batteries from years past.
This phone uses a Li-Ion battery, and these batteries do NOT have any kind of "memory." Charge it whenever you want to. However, it's not really good to always keep it "topped off." (Deep discharges are also not good.)
If you are going to store the battery, drop it to 75%-50% charged first.
There are some things to consider, however:
If the phone's power circuit bypasses the battery when the battery is fully charge (instead of constantly pulling power from the battery while the battery is recharging), then leaving the phone plugged in is better than constant charge/discharge cycles. Based on the fact that this phone will work properly with NO battery attached when plugged in, this is probably a true statement (but I can't know for sure.)
Second, the phone itself might like to see the battery charged/discharged once in a while to calibrate the battery monitoring circuitry. (You never calibrate a li-ion battery - only the circuitry that monitors the battery.)
Here's a link with some interesting information:
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
Take care
Gary
Got it. Thanks for all your information
A small note to add why you shouldn't 'keep' it above 80% (constant top offs and being left on the charger). In general when above 80% it's been found that lithium ion batteries have a 'higher state of activity'.
What that does to the battery is what it sounds like. Higher state of activity means higher wear and overall shorter lifespan.
That wear is easily seen in laptops. Many people have the habit of leaving them always plugged in while using and through the night, so they're always 'ready to go'. People who consistently do this to their laptops usually find after 1 year the battery life is noticeably shorter, 1 1/2 years 50% or so of 'new' capacity, and after 2 years looking at replacing the battery.
And I usually find a cheap deal on eBay for them, plus $50-75 for me. At least phone batteries are a bit cheaper.

[Q] Wiping Battery Stats

This was common on my droid x for so long while flashing but is it a good form of practice on the Rezound? The reason I am asking is I flashed Bamfs Cubed rom and my charging led goes from orange to green at 98%, never making it to 100. Would it be wise to go ahead and wipe battery stats and see if it fixes it? I presume there would be no harm to the system or battery in doing this.
Thanks!

There's really no harm in doing it but Google has come out and said that wiping battery stats doesn't do anything.

I always got a good laugh when people would post how "bump charging" & then deleting this file gave them an immediate dramatic increase in battery life.

Don't agree. Just like I don't agree with people saying task killers are bad. I guess with the way I use my phone I get different results. I have always noticed better battery life wiping battery stats. Now it could be that the OS will fix battery stats itself over time, but when you ate bouncing around a different rom every two days then the OS doesn't really get a better feel for the battery.
Plus...I came from the evo 4G where we uses trickle charge kernels and I want those back. Never had better battery life than when I had those. Was doing 35+ hours a charge on the stock battery.

Haven't bothered since I never could get the thunderbolt devs to try it. There was "reported" cases with no proof that it caused some batteries to go bad. Even then they were cheap Chinese batteries that 2 people total I think it was claimed went bad.
It was always nice to pull your phone off the charger in the morning at 100% instead of it showing 100% and you pulling it off the charger to say 92%.

Well there is the fact that Li-Ion batteries can not be trickle charged after reaching full charge...
Well they can, but it will hurt the battery. And that isn't me talking from a few bad battery posts... but from knowing how Li-ion batteries work and charge... and reading engineering papers about Li-Ion batteries.
Luckily trickle charging is slow and most people only leave the battery on the charger over night at most. Plus they charge while the device is running and using power. Should someone leave the charger going for 24 hours, with the device off, we would probably be hearing about a fire.
What is probably happening with these trickle charge kernels is:
The phone is going to use some power at all times, the trickle charge is probably just enough to keep the phone running and preventing the battery from draining slowly.
This works because there are two ways to handle full charge status while the charger is still connected.
1) When the battery reaches full charge, the battery is isolated from the device preventing the device from draining the battery. The device then runs solely off the power coming in from the charger. (this method would not benefit from trickle charging, and forcing the battery to continue charging will at best slowly hurt the battery over time, and at worst cause a fire/explosion)
2) When the battery reaches full charge, the charger is isolated from the device. The device runs off the battery until the charge drops to a certain level (usually around 90% or so) before charging starts again.
The second way is how the Rezound does it, and most other devices as well.
The first way requires the ability to switch instantly to the battery from external power without any drop in voltage. This is difficult to do, as a drop in voltage could cause the device to crash/freeze, so many devices do not use this method.

Well if the device was off then the kernel wouldn't be running and trickle charging the battery but when turned on and the battery fully charged they would very slowly charge the battery as it dies. So there should be no risk of the battery catching fire. And anyway, the way the evo trickle charges worked is they would charge your battery to a certain voltage. Once it hit that voltage it would stop charging until it dropped. So it wouldn't be hard to protect the battery.
Did this for 6 months on the evo with no issues.

[Q] Charging the battery all the way to 100% is bad?

...
Perform shallow discharges.
Instead of discharging to 0% all the time, lithium-ion batteries do best when you discharge them for a little bit, then charge them for a little bit. The table below, from Battery University, shows that discharges to 50% are better for your battery's long-term life than, say, small discharges to 90% or large discharges to 0% (since the 50% discharges provide the best number of cycles-to-usage ratio).
Don't leave it fully charged.
Similarly, lithium-ion batteries don't need to be charged all the way to 100%. In fact, they'd prefer not to be—so the 40%-80% rule you heard is a good guideline. If you do charge it to 100%, don't leave it plugged in. This is something most of us do, but it's another thing that will degrade your battery's health.
Fully discharge it once a month.
This may seem contradictory, but hear us out. While lithium-ion batteries shouldn't be discharged regularly, most modern batteries are what's known as "smart batteries". This feature can get miscalibrated after a lot of shallow discharges. So, manufacturers recommend fully discharging your battery once a month to make sure this stays accurate.

The only big no no is to constantly discharge to below 5% and recharge . That according to the experts leads to a much shorter battery life .
Yes leaving on charge is a waste .
Wiping Battery stats does not improve battery life .

there is a built in feature that stops charging once battery level reaches 100%. so there will be no harm to your battery. I have doing the same since gs1
My old Nokia 3510 needed a battery replacement after 4-5 years since it only held 3 days worth of charge instead of the usual 7-8.
I constantly let it discharge from 100% (overnight charging) to empty, the replacement battery cost me 5 bucks.
My Galaxy S1's battery has, after 2 years, no observable loss in capacity with overnight charging to 100% and dropping to 10-15% over 1-2 days.
A replacement battery would cost roughly 15 bucks.
I could go on the same about my Laptop, Netbook, Tablet and other devices with rechargeable Li-Ion batteries.
The point is; don't try to forcefully extend your battery life, enjoy your phone. Most people replace the phone every 1-2 years and the batteries are designed to live that long with high usage and deep-discharging. If yours should not or you plan to keep the phone longer, a replacement battery is cheap.

All Lithium batteries have it (and need it) since there is a risk of damage, fire or even explosion when it is overcharged. That's why not the phone but the battery itself has the corresponding controller. Since the controller cannot measure the exact capacity of the battery (only an estimate), it is recomended to deep-discharge and fully charge (charge-cycle) the battery once in a while to reset the controller's counter.
Battery replacement is cheap and easy as abc. That's the benefit of having removable battery. Just enjoy your phone.

[App suggestion] Battery Charge Limit

This is app is a must have and thought I'd share. Like everywhere I have read, they say battery should not be charged to 100%, it will hurt the battery somehow. This app "Battery Charge Limit" automatically (with root) stops charging the phone at whatever percent you want and starts charging back up at whatever percent you want. So you can always stop before it hits 100. It can be used without root but it only notifies you and you have to manually unplug the phone to stop charging. Better with root since its automatic.

Keep it turned off for a better batter longevity ??
Damn thos people are more preocupied of how to prevent the battery wear than actually enjoying this amazing phone
Well coming from an HTC device where after like what 6 months, my battery starts dying much quicker and hopefully this app and the nature of Samsung makes my phone battery last longer. Never owned a Samsung, so I don't know how the battery lasts over time.
This is a myth, modern phones already prevent damage from overcharging with the charge controller in the phone. Fast charging and slow charging also does not make a difference in battery longevity.
Just use your phone like a phone.
Yeah no
@nukeclears you need to bone up a bit more on battery chemistry before making statements like this. Overcharging is very different from charging to 80%. That's why Apple just implemented a charge limit in ios13 and Tesla strongly recommend charging to 80/90% max for daily use. Samsung just don't want to do this because they haven't felt enough pressure. I'll bet they implement it on the S11 and then for all phones by the end of the year.
Tab S4 has a setting to stop charging at 80%
You guys do need to go through all this? For what?
I have a Note 3 with battery since 2014 or 15, it still gives me the same power, sometimes it's better than it first was.
Charging fast/slow doesn't affect anything, I'm doing so for years.
I really don't think batteries die, if you felt it's weakening, just change OS, not the battery.
Samsung themselves, on the s10 series, suggest to charge from 30% to 80% everytime you need a charge.
In my daily usage, stopping charge to 90% is enough and I have all the juice i need till the next day.
If you are rooted, Battery Charge Limit app can be very useful to optimize the life of your battery (remember: battery is the first hardware component that ages your phone). On my 2015's Sony phone, they wanted me to pay 75 euros for battery replacement...
This thread is full of people who know nothing of batteries.
I bet your phone battery does "feel" the same after years when your os pushed that update that permanently limited your frequencys lmao.
