6) Don't charge your phone when it's at 40%. Wait till is below 10% and then charge it continuously till it reaches 100%.

9) NEVER charge your phone overnight. Your phone takes only about 4 hours to charge. Overcharging reduces your battery life

Are you sure about these? Because I've read that phones only take how much ever charge that they need, so charging overnight isn't a problem. And i've also heard that letting the battery charge fall below 40% actually reduces the life over time.
[Galaxy Ace S5830 General] I r o n M a n:
Yes, I am sure and it is something I have verified.

Overcharging kills the battery.

I saw a video once of an evo 3d. The battery almost completely died after it was charged for 3 days

And you should always charge only when your battery is low.

This will ensure longer battery life
[Galaxy Ace S5830 General] smanq:
Normally, when the battery is fully charged, the chip that controls the charging process reduce the current exponentially to 0: this avoid the overcharging.

I think all smartphones have the charging chip control integrated (an USB cable is simply a power source, not a battery charger), so I hope we can leave the phones on charge all the night without any problem. I do that always and never had problems.

Clearing battery stats has no effect whatsoever on battery life ...
[Galaxy Ace S5830 General] I r o n M a n:
Well, if you see again, I never mentioned that clearing battery stats saves battery. It is for those people whose phone charges very quickly with big increments, which typically happens after changing ROM's.

Quoting Dianne Hacborn(Android Framework Engineer):

"Today's myth debunking:

"The battery indicator in the status/notification bar is a reflection of the batterystats.bin file in the data/system/directory."

No, it does not.

This file is used to maintain, across reboots, low-level data about the kinds of operations the device and your apps are doing between battery changes. That is, it is solely used to compute the blame for battery usage shown in the "Battery Use" UI in settings.

That is, it has deeply significant things like "app X held a wake lock for 2 minutes" and "the screen was on at 60% brightness for 10 minutes."

It has no impact on the current battery level shown to you.

It has no impact on your battery life.

Deleting it is not going to do anything to make your more device more fantastic and wonderful... well, unless you have some deep hatred for seeing anything shown in the battery usage UI. And anyway, it is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point), so this would be a much easier way to make it go away."

:)

Its just a myth mate..
[Galaxy Ace S5830 General] Ajayr64:
And also, it's a myth that you should let ur phone charge reach 10% or get fully discharged before charging. This actually leads to decrease in the battery life over time.
[Galaxy Ace S5830 General] I r o n M a n:
I am aware of what you are saying and I fully agree.

But I have never mentioned that clearing battery stats increases battery life!

Tips to increase battery life are in the 2nd post. I simply said that if you clear your battery stats, UI will show you battery which is more accurate to the actual battery level.

Why are you arguing over something I never said?

[Galaxy Ace S5830 General] I r o n M a n:
Think of your battery as a person working out and charging is like taking rest. If the person's ability is to do 100 reps yet he takes rest after only 60 reps and keeps doing that continuously, he won't be able to do 100 reps after a few weeks!

You misunderstood me :'D

Clearing battery stats does not:

Affect battery life

Affect the battery level displayed to you

The only thing it does is, it wipes the history of battery consumption by each app. I am talking about the battery consumption by each app shown to you in Settings>About phone. If you clear the battery stats.bin file, the only thing that geta erased is this :)
[Galaxy Ace S5830 General] QNBT:
This! Anything about wiping battery stats is not a myth anymore, so please stop misleading people,

Also "6) Don't charge your phone when it's at 40%. Wait till is below 10% and then charge it continuously till it reaches 100%."

Not true! Charging your battery around 50% is the most efficient way to keep lithium battery alive longer. A discharge once a month is also recommended.
[Galaxy Ace S5830 General] I r o n M a n:
In fact, what you are saying is not true.

We should always let it discharge till 10-15% before charging. This is something I have checked up on.

A whole day of battery on CM10.1? What is your usage?
[Galaxy Ace S5830 General] Bakuron:
Having purchased my Ace in Dec 2011 and joined these forums shortly after, I'm a veteran of battery life discussion. I've underclocked my processor, installed/removed various battery saving apps, run various performance scripts, experimented with cpu governers and different ROMs, NEVER used 3G or WiFi (no home internet), had lowest brightness setting and more. All of this was due to living in a very poor signal coverage/reception area.

Having now moved into a good coverage area I can say with some authority that mobile signal is the biggest factor, by far, in battery drain. With full phone functionality enabled I've gone from 4 to 10 hours battery life.

Be aware of the signal quality and adjust your settings accordingly. In a bad area? 2G only, no WiFi/GPS/BlueT (alternatively if you have a strong home wifi signal use that and turn off mobile data). Lower screen brightness. Appkillers are useless. Battery stats don't impact actual battery performance. The actual software for reading battery life is hugely inconsistent so don't pay too much attention to it. For root users CPU underclocking is useful but only with careful manipulation. Going to extremes doesn't pay off. Also use AdFree to kill background ads in some apps, because they will keep running regardless of whether the app is or not.

"Commercial chargers do not allow changing the charge voltage limit. Adding this feature would have advantages, especially for laptops as a means to prolong battery life. When running on extended AC mode, the user could select the “long life” mode and the battery would charge to 4.00V/cell for a standby capacity of about 70 percent. Before traveling, the user would apply the “full charge mode” to bring the charge to 100%. Some laptop manufacturers may offer this feature but often only computer geeks discover them."

http://lifehacker.com/5875162/how-often-should-i-charge-my-gadgets-battery-to-prolong-its-lifespan

"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."

http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries

"Battery manufacturers ship batteries with a 40 percent charge. The low charge state reduces aging-related stress while allowing some self-discharge during storage."

(kinda related, that's for storing)

http://arstechnica.com/gadgets/2011/02/ask-ars-what-is-the-best-way-to-use-an-li-ion-battery/

"One of the worst things you can do to a Li-ion battery is to run it out completely all the time. Full discharges put a lot of strain on the battery, and it's much better practice to do shallow discharges to no lower than 20 percent."

[Galaxy Ace S5830 General] I r o n M a n:
I am quoting from the sources you mentioned

" Overcharging Lithium-ion

Lithium-ion operates safely within the designated operating voltages; however, the battery becomes unstable if inadvertently charged to a higher than specified voltage. Prolonged charging above 4.30V forms plating of metallic lithium on the anode, while the cathode material becomes an oxidizing agent, loses stability and produces carbon dioxide (CO2). The cell pressure rises, and if charging is allowed to continue the current interrupt device (CID) responsible for cell safety disconnects the current at 1,380kPa (200psi).

Should the pressure rise further, a safety membrane bursts open at 3,450kPa (500psi) and the cell might eventually vent with flame. The thermal runaway moves lower when the battery is fully charged; for Li-cobalt this threshold is between 130–150C°C (266–302°F), nickel-manganese-cobalt (NMC) is 170–180°C (338–356°F), and manganese is 250°C (482°F). Li-phosphate enjoys similar and better temperature stabilities than manganese.

Lithium-ion is not the only battery that is a safety hazard if overcharged [B/]. Lead- and nickel-based batteries are also known to melt down and cause fire if improperly handled. Nickel-based batteries have also been recalled for safety concerns. Properly designed charging equipment is paramount for all battery systems."

And again

" 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."

All those quote that you mentioned does not disapprove any of my points, i don't know what you're trying to prove here. Also I did mention that you should discharge your battery once a month.

To make it clear.

First link: mistakenly quoted the wrong section. lol, not really that relevant to my point.

Second link: Focus on "so the 40%-80% rule you heard is a good guideline"

Third link: Storing battery around 40% - 50% is the most efficient way, I also added the parenthesis to explain that this might not be relevant but still something to take note of.

fourth link: focus point "discharges to no lower than 20 percent", if 20percent is the limit there is no way one would want to go down to 10 percent as you recommended.

The info posted is very controversial if you don't provide any kind of source, but about the battery stats, that's nothing to argue about since that has even been answered by google themselves.

For my surprise today my phone don't respond, I left charging with the travel adapter, no boot, no Samsung logo, no recovery no download mode, maybe Is a sudden death problem :'(

I put my battery in the my wife's S3, and the battery is fully charged.

This is my last configuration:

Wanamlite rom 6.0

Philz touch recovery 4.63

Stock kernel (rom's kernel)

Last bootloader with the red light I in the upper left corner.

[Galaxy S III General] delsus:
You should have been protected from Phil recovery perhaps that line of kernel code doesn't fix SDS after all.
[Galaxy S III General] Glebun:
no, philz recovery would only protect him while he was in the recovery
[Galaxy S III General] Crest+:
So? what went wrong Mr. delsus?
[Galaxy S III General] drakester09:
This is very concerning but let's not jump to conclusions too fast, shall we? People would freak out.

Maybe someone can look over the leaked kernel and search for the SDS string (Movi ops or something :P).
[Galaxy S III General] x3sed:
No source, no strings... They said. (I already asked)
[Galaxy S III General] delsus:
Makes sense, so the real need for the fix in recovery isn't really needed, the chances of SDS in recovery are almost none existent.
[Galaxy S III General] jimbo77:
Of course they are existent... What if you are running a Nandroid Backup or you're installing a new ROM...

Those two activities take more I/O Requests to the memory chip than the "Normal" usage of the phone, you are reading and writting to the memory like crazy...

So the recovery fix is completely needed my friend...
[Galaxy S III General] delsus:
The majority of reports of SDS are whilst they are charging, also unless you flash more than 4 times a day you don't spend much time in recovery.

I haven't seen anything to say the amount of read/write requests affect SDS, its not the only thing that can make your NAND fail.
[Galaxy S III General] htcsnap93:
Must.... flash..... back..... to.... sds....safe....romm...

Oh wait, warranty ;).
[Galaxy S III General] t0n0n:
How old was your phone? Are you sure your memory wasn't damaged enough before the fixes got launched?

I can't figure out why Samsung shouldn't fix it for that 4.2.1 build. Maybe to screw leakers?
[Galaxy S III General] drakester09:
But Jimbo is correct - we don't know what causes the SDS but there is a very real possibility of a higher risk on more intensive IO operations.

This does not depend on time but rather on the wear of the EMMC, it has been theorized that the wear leveler is again at fault (like on S2 superbrick)

Recovery and restore are maybe the most intensive IO operations (besides installing AND the transcoding - which is seemingly done while charging, remember the Video Player CPU usage on that state... maybe that's the reason why it manifested... but I cannot tell for sure).
[Galaxy S III General] jinosong:

[Galaxy S III General] donalgodon:
Exactly. It is the correlation between charging and SDS which is quite apparent when analyzing the data thread that has led me to speculate that the factory charger may be responsible for this, or at the very least be exacerbating the situation. I've never used the stock charger, (mine is still in the box and I'm using the SII charger) but there are several reports of fried USB cables, etc. when using the stock charger, so I don't think it too far-fetched that they could be related somehow.
[Galaxy S III General] yahyoh:
stock charger has nothing to do with SDS its bug in the eMMC firmware :silly:
[Galaxy S III General] Glebun:
they would've issued a statement about it it though, because it would've saved a lot of phones
[Galaxy S III General] drakester09:
Yup, the thing is, apparently there is a TranscodeService for the Video Player that is triggered to start on charge, the operation should be IO intensive. That could be a valid co-relation. But the charger itself does not have any influence from what developers have gathered, it is a defect in the eMMC firmware.
[Galaxy S III General] Akshay (Aky):
This is really an great discussion

I wanted to know if I flash with any other kernel instead of stock, will there be even problem on leak
[Galaxy S III General] cgvelmax:
No exist another kernels, since Samsung has not released the sources.
[Galaxy S III General] t0n0n:
No custom kernel will work with the 4.2.1 leak. We need the kernel source code from Samsung to make the magic happen.

---------------------

And just after they release it(source), we will know about the SDS fix. And for the final release they will pack it on again.
[Galaxy S III General] ykkfive:
a TranscodeService for the Video Player that is triggered to start on charge?? oh really?
[Galaxy S III General] bulkmania:
i subscribe... i experienced 3 days ago same death of my S3. Worked 2 days on the 4.2.1 leak - now is gone. BTW, there is a solution to this problem other than service ?
[Galaxy S III General] Entropy512:
It should be possible to unpack the kernel image and check for the string VTU00M using "strings".

If you see MAG4FA in the kernel image using "strings" but not VTU00M, the kernel is missing the SDS fix.

If you don't see MAG4FA, you probably didn't unpack it right.

The only connection between SDS and charging is that charging holds a wakelock - which means lots of background I/O when you're not near your phone.
[Galaxy S III General] dogmatism:

I have been running the leak for 3 days now,no sds so far but if someone could confirm that the leak doesn't have the fix,I will downgrade to 4.1.2.Last thing I want is having to deal with samsung's service center.

Edit:already started downloading omega 4.1.2.I don't like the leak anyways.It stutters,no mods/themes/kernels for it yet and some features actually disappeared(ex: lock screen shortcuts) so it's not really worth risking to get into sds.I will wait for the final firmware.
[Galaxy S III General] Andrewtst:
Sometimes I have a feeling none of it actually solved it, it may prevent / drag it but not 100% cured.

[Galaxy S III General] Rob2222:
I have just extracted I9300XXUFMB3 kernel the same way like I have extracted the older kernels that I have checked.

I have found _both_ strings. VTU00M is included in I9300XXUFMB3. It also contains "movi operation".

This means we can assume / have a high probability that I9300XXUFMB3 includes the SDS fix already like all 4.1.2 kernel.

So the two(?) death cases seem not to be caused by a missing SD-fix cause the fix seem to be included. At least as far as we can check it.

Don't panik to much. Not every S3 failure is a SDS. It's normal that we have here or there a phone failure.

Absolut +1 that. IMHO thats the only relation between charging an SDS. More IO activity when device is on charger.
