I'm noticing that my phone tends to drop from 100 to 90 pretty quickly, but after that sips battery. Anyone else notice this? I got to 12 hours yesterday and still had about 50% left.

I wonder if it is something that your phone is doing right after you unplug it (maybe you can see it in the battery status or in Better Battery Stats) or if it is a battery issue.
I have a noticed a similar behavior but it is only when I use a non Samsung battery.
I have three batteries other than the one that came with the phone. I have one that is labeled as a Samsung that I bought on Ebay (it is a fake) and I have two Hyperion (that I bought on Amazon).
With the Hyperion batteries I have noticed that the battery percentage displayed by the phone will drop off very quickly as soon as I unplug the phone. After that the will last all day and seem to last even longer than the original Samsung battery. I suspect that it may because the cells are slightly different than the ones in the Samsung pack. I notices that the Samsung (original) battery is marked as 3.8V 2100mAh while the Hyperion is 3.7V 2200mAh. I am not sure if the voltage difference is significant but they do behave differently.
The fake Samsung battery from Ebay is a piece of crap and I will not use it anymore.
I mean it's not dropping instantly, it just seems to get to 90 faster than it drops after that. I'm still getting good battery life, it's just OCD that makes me annoyed by that initial drop.

That is kind of what I am seeing with the Hyperion batteries. It will drop to 97% within a couple of minutes even if the screen is off and I am not using the phone. It will get to 90% within an hour or so. After that the battery performs well.
Mine will actually stay at 100 for a while, then go from 99 to 90 pretty quickly. I'm using the stock battery.

The overcharge prevention circuit in the battery stops accepting a charge at 100% and allows the charge to decrease to around 90% before accepting a new charge. Even tho it shows 100% its actually somewhere between 90 and 100 depending on how long it sat fully charged before being unplugged. This extends the life of the battery and prevents damage from overcharging. Samsung doesn't fully disable the charge but doesn't allow a full trickle either it allows a very small charge to pass thru to try and keep it as close to 100 without overcharging, but background processes can drain the battery faster than the trickle can replace it

SBC is a form of trickle charging that puts out a full trickle which can keep up with background processes draining the battery. However, if you charge overnight while you sleep it is overcharging the battery for about 4hrs if you sleep an avg of 8hrs which isn't good for the life of the battery over time. The overcharge circuit is to aid in mitigating cell damage inside the battery. Li-Ion + heat isn't a healthy mix. It's like smoking a pack of cigarettes everyday and expecting to live to be 100. There's a trade off involved. The best way to get a full charge is to unplug when u get up let it drop a percent or 2 then plug it in while you get ready and let it.go back to 100%. SBC won't kill your battery over night but after a year or so don't expect it to hold a charge as long as it did when it was new.

Obviously worse with the USB charging. Barely charging at all that way, in fact. But even with the wall charging, it is very very slow -- anyone else having this problem? Any known fixes?
Yes I agree it is slow... Very slow.

Samsung smartphones are generally slow charging. My Nexus S 4g takes 4 to 6 hours to charge. Head on over to Samsung Galaxy S2 forum and you will hear the same complaints. Previous models, and I think Epic Touch are too, built to limit charge rate to 650 ma max. It may limit the charge rate even further if the phone is being used while charging.
This was the info I was able to dig up while researching the cause of my slow charging Nexus S.
Photon charged about 5x faster than my epic... So gs2 should be slower than photon..

Isn't the charging rate partially a function of the kernel? I could swear that one of the devs at SDX tweaked a kernel for the Moment, and one of his tweaks was "Increased power draw from USB for quicker charging."

I thought that the 3D had a 1730 mAh battery?
Not that its a huge difference, of course...
Wouldn't charging it slower allow the battery to last longer? I don't mean like longer as in on one charge, I mean like as in years. Batteries have a tendency to go bad after a few years of use and can't be charged the same way after a while. But afaik with smaller Ma being used, its supposed to delay the aging effect of the batteries.
My Epic 4G and now the Touch always have charged slowly. To combat this, I use my old Palm Pre charger dongle (the part the plugs into the wall) and connect the Epic's USB cord to it and things speed up a bunch. I'm not sure if I'm damaging my batteries, but I have done that for a year on my OG Epic and haven't noticed any battery deterioration. I also purchased a fast charger for the car and it does the same thing--very speedy. So I don't think that it's the phone or the cable or the OS, but rather the actual plug. So you might go and look for a replacement plug from another phone or a a generic one and use that to charge. It has worked well for me.
That's rediculous it shouldn't take more than 3 hours for a complete charge and 6 hours for a partial charge makes the device useless this isn't the 70'a
If you let the battery drain all the way, I'll get a full charge in about 2.5 hours. If you keep plugging in during the day, charging will then be very very slow.
My experience anyway.
First let me be clear that I am in no way connected to nor will I benefit from the product. If you are looking for an external battery you may want to check out the POP battery project at kickstarter
http://www.kickstarter.com/projects/siminoff/pop-the-intersection-of-charging-and-design.
It is a 26,000 mah charging device with 4 built in retractable ipad/mini usb cables and 2 more standard usb ports. I have pre ordered 2. I think they will probably be the last external batteries I will ever need to get because 1) they have standard usb ports and 2) the battery is so big, that unless we have a serious power outage I can never see my self draining it.
My next move is to put together a solar charging set up so that I could be off grid indefinitely
I've always wondered how effective these really are, looks cool though
I have 2 isound 16000's . I am going to take one to the airport with me to wait on my wife. It will run my flyer all night if need be. I have 9 callpod duo's they are good for one charge on my Evo
Thats a super cool battery backup.
I will keep a eye on this.
Sent from my LG-P999 using xda premium
Your battery looks interesting but as I check the specs... Your battery is 1700mah. A callpod duo is 3400 mah. The isound is 16,000 mah. The POP is 26,000 mah. If your phone will go two days on your battery it will last the better part of a month on a POP

For a little bit better comparison, awhile back I sat with my flyer, with WiFi on ,running Greader from about 9am on a sunday morning, The flyer was connected to the isound 16000. At 10pm that night the isound was mostly dead but the flyer was full. I wasn't straight using the flyer all day but the screen was on and the WiFi was on.
The Pop should yield similar results charging both the flyer and the EVO 3d with one acting as hot spot and the other tethered

Can anyone shed some light yet on the battery life for the Note 2 ? no matter where i look i cant seem to pin down any solid info on the battery life...
I know its a big battery at 3100 Mah but its powering alot of hardware so i would love a decent idea of exactly how long it will last under general use...
From the Phone Arena review:
http://www.phonearena.com/reviews/Samsung-Galaxy-Note-II-Review_id3134/page/4
Battery:
Armed with a beefy 3,100mAh battery, the Galaxy Note II makes way only to the 3, 300mAh one in the MAXX and MAXX HD phones of Motorola, but here the unit is easily removable and replaceable.
There are no official talk times yet from Samsung, but we made one very unscientific test to check how the Note II stacks up against the Note and the Galaxy S III during the HD Super AMOLED’s most frugal consumption times - video playback. We charged all three phones to 100%, put them in airplane mode, pumped up the brightness to the max, and ran the same HD video for an hour. At the end the Note showed 83%, the Galaxy S III showed 87%, while the Note II’s monster battery discharged only 8%, bringing it down to 92%. If we can extrapolate from that, the Note II might very well reach the RAZR MAXX’s 14-hour video playback at half brightness with this battery.
Looks like ZeroLemon also have a slim battery for Galaxy S3 at rated 2300mAh. Given my experience with their 6300mAh capacity battery being more than they claim, these 2300mAh maybe more than 2300mAh :fingers-crossed: Anyone tried this yet? I'm going to jump on this for daily use and have the extended battery for weekend use if this turns out good:good:

I have the 4500mAh battery and am VERY happy with it. I am not impressed by advertising that says "Highest capacity slim profile battery". That may be so, but you can only get so much power from a slim line battery. I thought I would never go to a battery that would require changing the size of my phone by putting on a different battery cover, BUT I'm glad I did.
The 4500mHh battery has been well worth it, IMHO. Got it from Gorilla gadgets, BTW.
Looks like it doesn't support NFC. I know that's a deal breaker for some.
I wouldn't trust anyone but Samsung to build a battery that fits under our stock battery cover that provides anything more than we already get.

Yes the instructions say charge for 12 hours before use and they have a break in of 5-6 charges for full battery life. Also they have NFC enabled crossed of in black sharpie on them the charger feels a little cheap too and flickers when you have your phone on the USB port while charging one oft the batteries. How they expect us to charge them both for 12 hours is odd the one I put in my phone charged much quicker than that and leaving it on longer is pointless as when they hit full safe chargers stop charging the batteries.
Battery 1 finished in 10 hours on the charger battery 2 finished in 2 hours in phone on stock charger stock battery is in charger now.
Charger had the following colors for led
Blue- no battery powered
Pink-battery charging
Purple- battery done
Also while charging and using the USB port is possible the charger led flickers when doing so. I don't believe it has enough amps to power both unfortunately. None of the batteries got warm at all while charging.
As for NFC Samsung should have never put it in the battery to begin with I'm thinking about getting a galaxy note 2 back pulling the NFC ant out of it and putting it in my s3 as they put the contacts for wireless charging and NFC external ant in our phones.

you can see the size difference in the battery size is major but the battery for the nexus does last pretty damn good for some reason. on the nexus battery on the side where the metal connections are i shaved off the tabs on that side look at pics lol

It might run okay for now, but in the end you'll blow up the battery and make the phone unstable. The GN3 battery is 3.8V while the GNex battery is 3.7V. Yes, that 0.1V makes a difference - the phone will charge the GNex battery with a too high voltage which can cause it to overheat and swell. The phone running off 3.7V will be underpowered and might or might not randomly crash.

It's not that big of a deal. Lithium batteries have an upper limit of 4.2 Volts which is why if you use a general purpose charger such as those used for charging RC packs you can charge Li-Ion and Li-Po batteries both on the same setting. Either way it charges them up to 4.2V and then cuts off. Once a load is applied, the battery drops to its nominal voltage - 3.7 or 3.8V and remains at that level for most of its life before rapidly dropping off when it gets low. When this happens cut-off circuitry kicks in around 3.2V or so to prevent the battery from discharging too much which will permanently damage it. Since the battery can't be safely charged above 4.2 or let drop below 3.2 or so, all the charging and discharging is managed by a chip designed for that purpose. Also, it means that you can't overcharge your battery by leaving your phone plugged in 24/7 as the charging chip will stop charging when it reaches that upper limit.

Lithium ion batteries with a nominal 3.7 voltage should be charged to 4.20 V or so.
Lithium ion batteries with a nominal 3.8 voltage are typically charged to 4.30 or 4.35 V. It's a new type of lithium ion battery with different chemistry, and hence the different voltages. If you take a battery meant to be charged to 4.20 V and repeatedly charge it to 4.35 V, its cycle life will be significantly reduced. 0.1 V difference will reduce the cycle life by something on the order of 50%. Here is a reference: http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
Apple, Samsung, and Motorola seem to be using this new type of battery, and the phones are charging them to 4.30 or 4.35 V. I'm not sure how widespread the technology is or if it has trickled into aftermarket battery offerings.

But with this new 'smart battery' and 'smart charger' system it seems very likely that the battery's capabilities are read by the charger so that the charger will not cause damage. It might be that the charger will adjust the charging protocol if it can support the battery's needs, or perhaps refuse to charge an unsupported battery. I think if he measures the charging voltage he might find that it is different for the two batteries.

Thanks to this, I will have more battery life. Cheers! Just kidding!
