[Q] Should I charge SM-G900F 6 hours (first charge)? - Galaxy S 5 Q&A, Help & Troubleshooting

Hi all,
Today I have purchased Galaxy S5 SM-G900F. The shop sales rep mentioned that, when I'm charging this phone, I have to charge it 6 hours (online charge), even if it's fully charged. They mentioned that that method will improve the battery life. Is it true?
I read somewhere that modern battery doesn't have memory effect. So should I plug my SGS5 G900F 6 hours?

Use it and discharge it under 5% then plug it in to charge it to 100%, that's all. No need for 6 hours charge on S5.

No you shouldn't. Nevertheless most people will tell you to do so anyway. The advice is intended to assure that your battery reaches 100% charge and gives you a good first impression of battery life. It's also stressful to your battery.
Ideally you'd charge to 85%, which is probably 0 - 2 hours charging depending on how much charge your battery has out of the box. Then aim for shallow discharge cycles thereafter. Running to depletion and high temperatures are the worst things that you can do to a lithium ion battery. And charging to 100% is stressful too.
Of course if you want maximum run time and will not be near an charging source, then you will probably charge to 100% anyway. A tradeoff between utility and overall battery life.
There are lots of existing threads on this subject, replete with useful information for anyone that does a search e.g. this or this.

Charging Nexus 7 before using it for 1st time?

Should I charge it for like 10 hours, then play with it? or you think its ok to just start playing out of the box.
I've heard stories..where you should, and where it's not necessary.
Thanks

Hmm, I see.:cyclops:
With every electronic gadget using Lithium-ion batteries nowadays, it doesn't really matter how/when you charge it.
Some would argue to make sure to allow a full discharge from a full charge from a battery calibration point of view, so the battery meter is more accurate. It wouldn't affect the health of the battery itself either way.
Things like memory effect doesn't apply to lithium-ion. How often you charge it and how much you charge it (full or partial charge etc.) doesn't affect it much either. The only 2 things that can potential kill a lithium-ion is high temperature and letting it discharge far too low to the point that it cannot be charged up again. Note that all electronic devices will power off way before it even reaches this threshold.
What makaijin says is correct
I had mine a bit of a charge yesterday but it was no where near full.
Used it till it was flat this morning. It's currently on charge and I'm going to leave it till it's full only because I need to stop messing with it and do other things

I charged mine for 4 hours before use.
Although it is probably not necessary nowadays, I like to fully discharge the device, then charge it overnight (so it gets back up to 100% and tops off), then cycle it that way 2/3 times, so properly "condition" the battery, as I don't 100% trust the conditioning done before shipping.
Just as a side note, most of the battery conditioning lore is coming from way back in the bad ol' nicad days (probably 1990's), when you HAD to 100% discharge/recharge the battery, and make sure it didn't overcharge or undercharge, else it would not be "conditioned" properly, and it had a permanently reduced max charge. Nowadays, expecially with Lion, it is not necessary, and may even be harmful to fully discharge/recharge cycle EVERY time you use it. The first few times it's probably best to do it to fully condition the battery, but beyond that, it really does nothing.

"Conditioning" does not occur with li-on batteries, period. Charging/discharging does absolutely nothing for the life of your battery.
Ifixit shows that the battery inside the Nexus 7 is Lithium Polymer. Does that make a difference in terms of conditioning compared to Li-Ion batteries?

Oh, thanks. I thought that was my being paranoid .
Lithium Polymer batteries are actually worse than Lithium-Ion. Don't take my word for it, but at least with older RC Lipo batteries, fully discharging damages them even more the lithium-ion. I am sure the tablet cuts off way before the danger point, but still something to keep in mind.
Here's the deal- and this has been verified on multiple devices with larger batteries- Your tablet will need to self-calibrate the battery meter/charging to the battery. You can expect things like sketchy battery life and running down very low or completely overnight for the first couple days. Once everything "syncs up", you can take advantage of the full potential of the battery. This happened with my Razr Maxx and it happened on my Nexus 7's first overnight. And, talking to people who have had their Nexus 7's a few days, it's common and expected.
As said, it is NOT the battery conditioning, it is the device calibrating. The battery is pretty big and there's a period of time while the device learns.
I decided to drain the battery all the way and then charge it all the way up. It's charging right now actually, any idea how long it should take to get up to 100%?

Over discharging a Lithium Ion battery can ruin it in a single cycle. Of course any consumer device should shut off before that happens but deep discharges to the shut off point still permanently reduce battery capacity significantly more than shallower discharge cycles.
In simple terms, you'll get significantly more hours of battery use during its lifetime if you only discharge to 50% than 10% or less.
Lithium Ion batteries never need to be "fully discharged" to the device shut off point and as stated above, it isn't "good" for them.
That said, a discharge from fully charged to at or near shutoff let's the device software measure the battery capacity more accurately so you'll get a more accurate battery reading.
Lithium Ion batteries should not be charged at elevated temperatures. If you just watched a two hour movie, let it cool down before charging. A tablet is a nasty place for a battery with the CPU heating it up. Most manufacturers advise not charging at > 85 deg F and 70 deg F is better. A really good charger will measure battery temperature and reduce the max charging rate at elevated temperatures.
Lithium Ion batteries should be stored at 50-70% capacity and not fully charged. That's ~3.7 V per cell. Those of us who use the device a lot on external power would see a lot longer battery life if there was a mode which allowed keeping the battery below 100% while on external power. It seems every manufacturer thinks consumers are too dumb to understand the value of providing it and switching to full charge mode before we run off on battery power.

I would rather always have my battery near max charge when I take it off the charger than have a battery last 7 years instead of 3 or 4 in a device I will realistically only use extensively for 2. Even more so with a phone where they battery can replaced for $20. I'll take a full charge every time over the battery lasting for years longer than I need it to.
I have a first gen iPod Touch I bought when they were released (2007 I think?). I have left it on a charger for MONTHS. Still holds a decent charge.
Is there benefit to using a battery calibration app like this if you're rooted?

You don't have to but I like to. Mine was like 40% charged when I unboxed

Calibration occurs every time the battery is charged to 100%. It isn't a "first few days" type of thing, it is every single time the battery meter reaches 100%.
I had no choice but to completely charge my N7 (purchased from Office Depot 7/14). When I went to turn it on the first time, I was greeted with small text in the upper left side of the screen that said "show low battery logo" on a completely black screen. No logo...no nothing. Completely blank. Plugged it in, the battery charging logo popped up, fully charged it and it's been working great since.
However, I found it a bit odd as I thought most of these types of devices ship with about a 40% battery charge.
Thoughts?

I hope you dont do that for all your phones as it will destroy your battery way sooner. Charge it when it reaches 50% and you can do 3 to 5 years with the battery at 24/7 use. (Instead of the 1 to 2 years when draining the battery).
Yes, it is recommended to charge the battery when it below 40% and disconnect the charger when it reach 99%. Do not overchange.
There was a big test I did read and the best was to keep it between 40 and 80 percent.

charge it when it prompts you to charge. at 19% you start getting the first recommendation in lockscreen, then at 15% you even get an annoying prompt.

Are you guys seriously sitting and watching until the battery goes down to certain percentage? And for what? Battery is easy to replace and not that expensive, it has a circuit to protect it from over and under charging, to avoid the damage and you get many more shallow charge/discharge cycles than deep ones as already mentioned. I charge my phone daily in the evening at my convenience, usually before I go sleep regardless of what's left (unless I use it so much it can't last until evening), so by the time I go sleep it's 100% and by morning it will be around 97% and normally last me whole day. I've been doing this for yrs and for example my 4yr old Nokia I gave to my friend, still lasts him couple days of light use on original battery. I wouldn't worry about it at all. Every few months you may want to fully discharge it to lets say 3-5% to have the meter calibrated and maybe clean the contacts with alcohol every six months or so, but that's all the maintenance my battery will get or need. If it fails before the phone, it probably had some factory defect or something, but no big deal as long as there is replacement easy to buy and with so many millions of notes sold, there should be.

Couldn't agree more, I charge mine on a evening regardless and phone gets me easily through a day. If I notice a massive drop in the battery not holding a charge then I will buy a new one. More important things to worry about in life than watching my percentage for the battery.

That is good as a principle but the numbers are still rather big and depend even more on the charging current - if you charge (even) from 50% with 2000 mAh it will never last 1500 recharges - that is why Samsung has slightly improved the Note 3 recharging algorithm so as to use (variable) lower currents (even if the charger is 2000 mAh), and also why it is still far, far better to recharge from a very good USB at under 500 mAh (actually 450) - and indeed preferably from over 40%.

As long as the charging current is lower then 1C (1 full charge for the note3 its 3200mAh) its not a problem and wont shorten lifetime.
But yeah charging at lower currents is better, but more due to less heat and induction.
Anyway its just sad that other people with little to no knowledge about lithium batterys are giving advice, and WRONG advice at that.
Just read the link i posted in previous post (page1) there are the facts. Dont believe just anybody, people are stupid. (yeah im people too )
The chemical reaction will be less when battery is drained and is hard to recover.
But if the battery seems dead, put it in the freezer for 2 or 3 hours and it will be recoverable.
Theres more to these batterys than people think.

[Q] How to Charge Batteries .....

I know there is already information on this topic ..... I have read conflicting advice on how to charge cell phone batteries, but I want to make sure and get the maximum use and life from the ZeroLemon 10000 Extended Battery for my Note 3 .....
The directions from the company simply state to give six full charges, but there is no explanation exactly what that means. I have sent the company a question regarding this issue, but still have not yet received an answer .....
I just finished the third full charge. When I received the battery, I charged it for 12 hours before unplugging from the charger. Then allowed my Note 3 to go completely dead (to Zero %). Then charged again for 12 hours. Did this three times so far.
I'm only getting around 37 hours of medium to heavy use, or about 1 1/2 days, and around 18-20 hours of Screen On Time, which seems somewhat impressive!
After I go through six charging cycles, should I always charge for 12 hours, or is this no longer necessary?
-- Jim
Based on what I read in charging lithium ion batteries ( which I also practice ), you don't wait until battery discharges to 0 before charging it since it shortens the life span of the battery by damaging the negative electrode. The recommendation is to charge it once it reaches 10% and don't have to fully charge battery to 100%, just around 90 - 95%. Since lithium ion batteries don't have memory effect, partial charges and discharges don't have negative effect on the overall battery life.
Didn't made this up, just quoting from memory.
Never let my stock note 3 battery go below 5 percent. I am getting great battery life. The same with my old i9100.

For the 1st Time or after You Flashed any ROM/Firmware You Should Complete 3 Complete Cycles of Battery To Get The Best Results...
Charge 100% To Discharge 5% (Do Complete 3 Cycles )
Regarding Charging You will Not be need to Put Note 4 All Night Charging or Stuff like More Charging Then 1:30hours,Because it Have Adaptive Fast Charging Battery Will Charge in 1:30Hours & Give you 5:30hours SOT (it Depends on your usage also)...
Now Mostly Smartphones Have Built-in Feature To Stop Charging When It's Fully Charged...So No Need To Worry...But Every Battery Have Some Cycles when You reach that then battery will drain Fast or we can say You'll be in Condition to replace the Battery...But Will Easily Last for 2 or 3 Years To be Weak on...
Hope will Solve your issue
Okay thanks so much so basically I'll charge it to 100% without using it I'm guessing it's a quick charge so it wouldn't be an issue for me then use it to 5% 3 times sorry I'm a.d.d. So had to make sure I read what you said correctly and I'm not sure if I'm gonna root it when I get it phones no days are actually beginning to meet my standards speed wise lol thanks for the info
I've found no noticeable difference in following different guides on charging. Turn off fast charging when not required as that'll duff up your battery in 6 months.. Normal charging provides a nice slow rate and ensures they don't get hot which degrades them. A new battery will take a few full charges to get to full strength.
A new battery is like £!2. Don't worry about doing rain dances and such like!
Batteries used to hold a memory effect which made it look full before it actually was - this isn't the case anymore.
Fast charging gives me an hour less per day over constant charging normally. Note sure what others have found. I charge overnight hence turning off fast charge, and have a couple of spares ready to go should I need it.
i charge 14 hours and then use it normally. no need for anything more than that.

A (new) way to increase battery life on the S7/Edge

Hello,
I am doing an experiment since few days ago. I noticed that if you disable the Fast Charging, and (most importantly) use a proper, thick 2A USB cable (I use a Kindle Fire original cable) then the battery lasts around 15-20% longer.
How to recognize that you got a proper USB charging cable ? With fast charging disabled and the battery empty, the phone should tell you that there are around 2 hours until full (instead of the usual 7 hours or so with fast charging disabled). That's when you know that you are using the proper cable. I bought a original Kindle Fire cable from Amazon and that is very solid, much thicker than the standard cable. See attached screenshot. With the standard cable this seems to be a hit and miss, you sometimes get the 2 hours message and sometimes the 7 hours message.
I repeated the experiment 3 times and each time I got significantly better battery life than before.
You may want to try it to see if it works for you.
PS: Attached is my latest battery life screenshot (APC8 firmware), which is the third charge since the experiment. 2 days 6 hours of stand-by with 5h SOT on a mix of 80% Wi-Fi, 20% 4G with nothing disabled (even Bluetooth is permanently connected to the LG smartwatch). Almost no videos played, only web page browsing which is quite demanding on battery.
Look if new software update is possible.
Yeah, I noticed that my battery life was worse when I used a ****ty 1 Ah Sony charger when I displaced the original Samsung charger. It took about 3 hours to charge it up to 100%, but then I noticed that the battery life would be worse than before. I found the original charger again, and battery life is back to being good again. I never use fast charging, unless it's in the middle of the day and I'm heading out or something.
None of the things mentioned above should (technically) have any impact on battery life once unplugged? I mean, stored electricity is stored electricity, so if someone QUALIFIED could give an explanation here, it would be cool.
Nothing new, I've always noticed that if I charge the phone with the original charger and fast charging disabled it will last much longer.

This cable? Which AC adapter do you use?
None of this solutions should impact battery life Oo. Energy is energy, no matter where it comes from?!
Would be nice, if someone qualified could tell us more..
Do you have the newest android version installed?
By the way, I only charge with original charger and cable, fast charge disabled (battery life is longer?!)
Battery life depends on how well you follow charging & discharging cycle. I usually fully discharge my battery (so that phone will shut down by itself after dropping below 1% charging), then charge it fully keeping it switched off & then use it.
I always had far better battery life than most people complain about.
BTW, I also tried charging battery keeping phone switched on at 10-15% charge remaining, battery definitely performed weaker for my use.
So that confirmed my theory based on my usage over last 7 years..

I wonder if Qnovo is qualified enough ? Their technology is employed in many charging solutions. Here is what they say:
"Add fast charging - it gets noticeably worse. It turns out that the simple way batteries are charged today causes most of the damage that leads to shorter daily battery life and reduced lifespan."

So you're saying that Kindle Fire cable extends battery life? Isn't 100% battery life from one cable the same as 100% battery life from another cable? Energy is energy.

In no way I am saying this. I am just saying that you need a cable that reliably supports 2A charging, so the charger shows 2 hours to full instead of 7 hours to full, even with fast charging off.

Ah okay. I went ahead and bought one!
It ' also the logical thing. With fast charging , the battery holds less charge than the "normal . " He just spoke in various forums of this.
Anyway , great idea.
How to maintain max battery life span (reliable source):
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. When possible, keep it in that range to prolong its life as long as you can. And, 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. If you need to charge it overnight, use something like the Belkin Conserve Socket to stop it from charging after it's full.
·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", which means that they can tell you how long you have until your battery dies (e.g. "2 hours, 15 minutes remaining"). 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.

In no way I am saying this. I am just saying that you need a cable that reliably supports 2A charging, so the charger shows 2 hours to full instead of 7 hours to full, even with fast charging off.

But you stated that it increases battery life.

So you're saying that Kindle Fire cable extends battery life? Isn't 100% battery life from one cable the same as 100% battery life from another cable? Energy is energy.

What he's saying is that a slower charge equals a longer lasting battery between charges.
But maybe that doesn't apply to Li-ion batteries, according to this link here.

You can try it for yourself (if you have an S7/Edge) and report the results here. I posted my results, I'm not an expert, I just tried this. I also tried the 7-hour slow charge (with a different charger) and it didn't work as well as the 2-hour charge. The 2 hour charge seems to work best.
Yeah, If you use fast charging the battery dies a little bit quicker. I recommend fast charging if you are in hurry.
I only use fast charge when I'm in hurry.. Nice feature! I try to charge my phone between 25-80%...

Battery life depends on how well you follow charging & discharging cycle. I usually fully discharge my battery (so that phone will shut down by itself after dropping below 1% charging), then charge it fully keeping it switched off & then use it..

Worst thing you can do for the lifespan of an Li battery.

I disagree, even though it switches off itself, it still has charge, don't go by it says 1%.. so it's not fully discharged... besides my method served a good battery life to me over the years with earlier phone models
