Battery life

Seriously?
Is it just me or have others seen their battery drop half after an hour of on and off browser user w 3g (auto brightness)

don't charge it via A/C adapter if you want better battery life.
and how many times have you cycled the battery?

How much is your screen awake time? if it is more than one hour+ 3G so yes it is normal.. This phone needs an extended battery fast

Just don't charge it at all. It's so stupid to charge your phone, nothing good comes from it! And if you need to charge, NEVER, use the A/C Adapter that came with your device like paOol said!
/Sarcasm off

Your USB cable isn't braided with 24-strand Unicorn hair. Therefore the power coming from the charger isn't pure enough for our Galaxy Nexus.

Stupid as it sounds, there is some truth to it (though OP probably didn't know, lol). Quick chargers wear out the battery a bit faster than a slow charger, so charging from the usb port on your computer is slightly better for the battery, but the charge takes a lot longer. This does not affect your battery capacity per charge, but affects how many cycles the battery lasts before it wears out.

This guy knows!
Lithium ion batteries actually like a slow charge and discharge rate . By that I mean to prolong the cells life and IRS storage capacity. Optimum rates vary a little but I found in testing that makita lithium batteries provided best service with .5C charge and discharge rates...
Not exactly the same as your phone battery, but the same chemical make-up inside the cells..
Anyway.. lol

hahahahah yes.
I heard that if you use a potato to charge your phone it doubles the battery capacity.

that seems about right to me. I browse a lot and routinely get about 3.5 hours screen time before my phone goes to the red zone. Which IIRC is around 15%?
I have my browser open and the brightness to 40% and my bluetooth off.
The battery life has been the sole black spot in owning this phone so far. I am sure the owners of the next generation phones will make all of us jealous. I bought a spare -regular- battery for just this reason.

if you want your phone to be ugly as **** and look like you have a tumor on your leg you can get this

i-Blason PowerGlider Battery Case in Stock

And quite a bit more expensive. The only real difference I see is the charge rate. IIRC I read somewhere the Mophie covered the power button and I use the IR blaster. Either way ill give this one a shot, if I dont like it ill check out the Mophie.

The output of 500mA convince me not to be a guinea pig for this case.
I'm convinced that's just not enough power to charge up the phone while in use. Also that rate of output I'm sure it will take hours to change a phone.

I dont need it to charge. I just need it to sustain power. If both the phone and case are full just turn the case on so it discharges first. Its perfect for me, itll keep my phone topped up while im at work and not using it much.

The phone should stay charged if you don't use it much even without the case. I'm not sure what's the purpose of having a case if you're not using the phone, it will stay charge while not in use.
I personally need the case to be able to charge my phone up or hold charge while it's propped up streaming a baseball game with the AtBat app.
But I know for a fact 500mA just won't be enough power for the phone to hold a charge while in use. You will actually get power drain while in use.
Either way guys let me know how it goes I'll keep an eye on this case.

No offense, but what's your problem with this? Batteries drain when in use, period. If you're using a battery case, then the batteries are still draining. If I wanted to actually charge my phone, I'd use an external backup battery or AC-- I'm ordering this case to extend runtime by slowing consumption rate.
It just seems like you'd be better suited with an external battery.

I don't think you used the mophie juice pack before because it actually charges up the phone while you using it. That's a feature I actually need because I will actually watch a baseball game or two while at work and don't want to be tied down to a power cord.
With the Mophie case I get 2 full charges and what ever time it took the case to fully charge the phone. Needless to say I'm cordless for a whole day with heavy heavy usage and constant screen on time.
I want this case for the simple fact it has a kickstand but besides that what's the point in having this case if all it does is charge the phone while not in use. And it does a poor job at that too because it takes up to six hours to get the battery fully charged if you don't use the phone.
Does this case actually extend usage by slowing consumption rate? By how much is the question. I don't think much with the .500mA out put.

Different users, different use-cases. "Not in use" means different things to different people, and my phone consumption is tweaked to be pretty low. As is I usually get through the day with about 30-50% left at the end; while I'm walking around at work, it's just playing music or I'm using a tablet to watch video instead (since I don't want to use my work machine for that...you can guess why ). Since my phone cycles down a lot of the time, 500mA is enough to trickle charge when I need it, and slow usage (by the USB charge rate, which is hardly shabby) when I am.
Since I don't need to use my battery aggressively, there is certainly a point for my use-case. And I really can never see a situation where I would want to charge my phone completely. If I really had to, I have external batteries for tha.t

Source for GOOD batteries?

I'm getting pissed with all the POS oem batteries for the S3 these days. Is going to Samsung direct my only option to get a GENUINE one? I don't see where they sell them and I don't trust eBay based on experience.

I know you can get them at Office Depot. Or you could at least, several months ago.

Sure. Brand new phone just purchased. Very few programs installed. Battery used was purchased off eBay. When indicator light showed fully charged I unplugged. Battery remaining went immediately from 100% to 88%. After 6 hours of light use, battery was already down to 40%. Within 20 minutes it fell off the cliff and phone turned off ... basically fully discharged.
Next, stock battery installed. 1 day 12 hours later battery still shows 55% remaining.

In that case I'd recommend Monster ZeroLemon 7000 MAh again.People here on XDA have really tried to suck every drop of juice out of it. It had stood all that abuse very well. Buy it from Amazon so you have solid Return Policy in case of trouble.

Thanks, I'll seriously consider it though the added thickness is a concern. If I could get 2 extra batteries close to the performance of the stock battery and at a combined price close to the ZeroLemon I would be satisfied.
How long does it typically take to charge one of those monsters?

I don't think their form factor would have issues with the SIII's casing.
I do believe they take roughly 4 hours or so with Samsung's original Charger. I don't have one myself so I have second hand information. It is true that if you have a Fast Charge Kernel, this is further reduced. I am guessing, if you charge off of a PC, of course it will practically take forever to finish :laugh:
My 1 year old stock battery goes me 3 days if on Standby all the time.It will last 1 & 1/2 to 2 days if I use conservatively.

Just fyi, fast charge kernels only make a difference when plugged into a PC and maybe a DC (car) outlet. And correct that the batteries should be the same size and ought to work fine. Only real thing to make note of is if you use any NFC features make sure the battery you get has this capability.

Bit OT here, but my regular Kernel KT747, now (in recent version) has special code for the 11th pin of the MHT port. So I am given to understand the Fast Charge thus implemented actually affects the way it charges off wall. I am testing since yesterday.

The theory behind fast charge kernels is that when you plug into a PC it detects the data connection and limits charging to 500ma or so. Fast charge kernels allow you to disable the data connection, thereby fooling it into thinking it's plugged into a normal charger and bypassing that limit.
The extra pins don't have anything to do with charging. Only 4 of them do. Before fast charge kernels were introduced people would sometimes short two of the wires in the connector (usually with solder) to accomplish the same thing.
As I understand it the 11 pins are just used with the MHL adapter for HD output. They don't have anything to do with charging. Otherwise a basic USB cable probably wouldn't even work.
I believe there are a few in depth write-ups about fast charge kernels here on xda if you want to search for more info on it.

New to wireless charging

Hey people,
New to wireless charging here, my girlfriend just bought a wireless charger for my birthday. Just one question, when you are charging and you need to use the phone, should I pick it up or leave it there and try to use? I mean, if I keep picking it up to use, wouldn't the constant charging/stopping damage the battery? Please help me out!
Thank you!

No, it's fine. Pick it up as many times as you want. I have different wireless pads scattered throughout my house, office and car, that it will not "hurt" it.

It's probably fine. But if by constant you mean literally every 5 seconds then maybe not.
Also there's a xposed mod to disable the sound every time you put it on the pad if they annoy you too constantly.
BTW it'd be great if I had a techy girlfriend

thanks for the comments guys

AFAIK li-ion batteries does not suffer from any memory effect and they even last longer when kept charged. Battery charge cycles are still there as an indicator of the goodness of the battery from the manufacturer but they are related to a full cycle (eg how much current passes through the battery) but smaller charging cycles shouldn't be counted as full.

Could you provide some references for our edification? I admit I'm not the most knowledgeable on the subject but my understanding is that charge cycling is bad at or near full charge. I don't know that this a problem at lower charge levels (let's say <90%).

I don't have an EE degree but from what I understand newer batteries cycles are a full charge from 0-100. I read something on apples' website explaining this. So charging it twice from 50-100 would be one cycle.

You might be right about the charge cycles, as most things seem to relate to amount of power transferred through the battery, and not 'depth of discharge" but honestly many people I've met who plug their phones in all the time to top up, end up having to get the battery replaced after a year. Apple product, ok no problem they do it free for like 2 years; but I've done nothing but run my batteries all the way down every time and slowcharge every night on USB-500mA (gentler current, kinder to battery, cooler temps, and even a slightly more thorough charge) (just 5% POSSIBLY 10% it's hard to say...probably 5%...I guess I should test this)

Not best, but I have resigned myself to the reality of potentially replacing the battery in 18 months if I want the convenience of charging pads everywhere. You might wish to think this way as well. Also, after 18 months, maybe you could just charge it at every opportunity (at that point, who cares, you only need it for another 18 months probably) and that would be enough.

All I know is since 1998 I charge my phones to 100% as often as I can find a charging device. I am the only one on my family plan of 5(the others run battery down daily to~30% or more) that doesn't replace their battery before their next upgrade. So my motto is *Top up every chance you get*.

Not sure if it makes a difference but nexus 5 uses newer li-po batteries not li-ion.

Phone abruptly dies under 20% battery

Phone totally goes black/dies when battery is 21% down to 10%. does this just mean the battery I have is bad? What replacement battery is best? I've read Anker makes a good set with charger. Thanks.

Samsung SDI batteries are the only batteries I've known to do this. When screen goes black, that should be a shutdown. Do you plug in your charger at that time? Mine actually actually showed 0%.
It's inconvenient for a battery to shutdown unexpectedly, while showing capacity remaining. I always replace Samsung OEM batteries with another brand. I found one that I liked so l went to Amazon and bought a second plus external charger from same brand. If looking at another alternative, just search MPJ and read the reviews. The battery and wall charger were on sale last week, maybe still.
If you're considering upgrading to sealed battery in unibody phone, you should consider the care required for such a phone to get battery to last. Sealed batteries are actually very similar in capability and ratings; no leap in tech but apparent shortcoming evident in Note7 embarrassment. Fast charging produces heat and steals life from battery's endurance down the road. Studies have shown since lithium batteries have no memory that you're actually prolonging the battery by slow charging without load or minimum load and bump charging rather than cycling battery to near 0% then back to 100%. Manufacturers don't tell you that because they prefer you wear your battery down in less than a year's time and consider another phone purchase.
Maybe Samsung would be better off today if consumers were more aware of how to prolong lithium batteries?
If you want your battery to last two years, bump charge it after 25% used as much as possible; it shouldn't even matter if you bump charge it 3x per day. Avoid fast charging and heat cycles. IOW, try not to use it while charging; the cycles should be short anyway.
Or, if you prefer to abuse a removable battery like the Note 4 and care less, pay about $15 and just replace the battery every year. 500 full cycles is all these batteries are currently rated for due to increased degradation with abuse. Mini cycles allows more of those cycles without degradation but you'll still have capacity when you need it to last a long day without charging.

Wow thanks for all the information. What does bump charge mean exactly? Now my battery won't charge passed 90% either. A different one is on the way.

Try this, if you are rooted and have recovery wipe dalvik cache and cache. Power off phone and pull battery for like 5-10min. Hold the power button (with battery out) for like 1-2min. After letting battery sit out for 5-10min reboot and see what happens. If same instances occur. Your battery is dead just purchase a new one! Anker recommended!

You're welcome.
Bump charging is partially charging before battery gets low. An example would be running the battery down 25% and charging without overcharging it.

Had the same issue, bought a new Anker and issues resolved, the stock Samsung sucks!

I'm just glad there's a way to replace it that'll mean this phone can last a long time if I'm careful with it.

Yeah it must be these batteries. My mom has the Note 4 as well and hers does the same thing. As does mine

Yes the stock Samsung batteries are horrible. They don't last very long then they start misrepresenting the battery statistics to the OS so you get the shutdowns at 20 or so %. I switched to a twenty$ Anker I found on Amazon over 6 months ago and never had the issue occur again. Even thy sprint techs will tell you if you ask them outright!
