Have a Samsung Galaxy SII - T-Mobile phone... love my phone but the battery dies so quickly... do they have a longer lasting battery for this phone yet?
Root the phone. I used to get only 6-7 hours. I now easily get 14-16 hours.
Once rooted you can do a number of things to make the battery last.
If you don't want to root (which I would recommend) you could try 2xbattery app from market. It works wonders.
oh,
is the NFC antenna the only difference between the aftermarket batteries and the stock battery? I was looking at picking up a few higher capacity batteries for traveling on my bike. i would not be using NFC then, so I guess i would be ok getting some!
...
An alternative is to get an add-on battery that plugs into the USB/charger socket on the bottom of the phone. Then you won't have to worry about the physical dimensions of the battery or the NFC antenna.
- The batteries in the T-Mobile SGS2 and the AT&T SGS2 Skyrocket contain the antenna for NFC communications. Even if you find some htird-party battery that is physically the same dimensions, it probably won't have the antenna.
John Jason and Crystal,
Not to contradict you, but I just spoke with a Samsung representative over live chat a few minutes ago regarding this very issue and the answer that I received about my Galaxy S II Skyrocket is that the NFC chip is housed within the phone itself, not the battery. Why the battery says "Near Field Communication" on it if this is the case is beyond me, but, to me, the answer makes sense. Authentication would be a rather complicated feat for those who wish to make use of multiple batteries, as many are wont to do. If each battery housed a unique NFC chip, each battery would have to have a different unique ID associated with it, which would then have to interact with the phone.
Though I'm not 100% up-to-date on the technical workings of NFC, I do know that this is a possibility, as NFC chips require very little power to operate, but my doubts arise when I think about the chip's interaction with the phone if it is housed on the battery. I see no special contacts in the battery compartment of my phone that would indicate some sort of direct connection with the chip itself and I do not think that the relays that provide power from the battery to the phone would be an efficient data transfer medium.
So far as I know, all other NFC-enabled devices have opted to install the NFC chip itself within the device proper, not the battery, though Samsung is prone to wild flights of whimsy when it comes to design.
I will provide an excerpt of the transcript of my chat session with the Samsung rep. I should also note that, though the rep states clearly that the chip is inside the phone and no special battery is required to power it, he/she did not know whether a third-party battery would work with NFC functionality. My feeling is about 90% yes, seeing as no special power standard for NFC exists (as far as I know through my research), but you never know.
Transcript:
Visitor: My question is specifically about the location of the actual NFC chip. Is it housed within the phone or inside the phone's battery? If it is inside the phone, is a special battery required to power it?
Jamie: The NFC chip is housed with in the phone and there is no special battery required to power it. It works with the provided default battery only.
Jamie: Is there anything else I can assist you with?
Visitor: So as long as a third-party battery is designed to fit and work with my Galaxy S II Skyrocket, NFC features will work, once they are activated by Samsung/my wireless carrier?
Jamie: Yes, the NFC features will work with the default battery on the phone.
Jamie: Do you have any other questions?
Visitor: Yes, will NFC work with a third-party battery?
Jamie: I am sorry, as I may not able to provide you the exact information regarding that. However NFC works with the provided battery in the phone.
Visitor: Well, thank you for answering as much as you could.
Visitor: That's all the questions that I had for today.
Jamie: I am unsure if it works with the third party battery or not.
Jamie: You're welcome.
Visitor: I will continue to research, then.
Sorry to quote the entire long post, but there are several points that kimj2y failed to grasp and failed to ask the representative, and that the representative did not clearly mention:
1) Yes, the CHIP is inside the phone.
2) No, the NFC will not work with third-party batteries because the ANTENNA is inside the battery. Even if you find a third-party battery that is the same dimensions as the battery in the T-Mobile SGS2 and the AT&T Skyrocket, it is doubtful that they will contain the antenna.
If you want NFC to work, either buy a genuine Samsung battery for the T-Mobile SGS2 or the AT&T SGS2 Skyrocket, or take LunchBB's advice and buy an add-on battery.
And having said that, chips and antennas notwithstanding, NFC won't work at the moment anyway, because the software is not yet available.
Plus, I should add that Phandroid recently announced a new SD card that contains everything for NFC, which will make NFC possible on phones without an NFC chip or antenna.
