Anker External Charger question - AT&T Samsung Galaxy S II SGH-I777

I am not familiar with batteries for our phones, I used to have an HTC Inspire and I purchased a Anker External Charger with 2 batteries. like shown here. I would like to purchase another OEM battery for my SGS: II, can I use just the external charger that came with the Inspire Anker Batteries for my SGS II batteries? That way I can always have a full battery instead of worrying about my phone dying. Not sure if it's possible or even recommended and figure I'd ask.

I'm not sure about what's recommended but I'm currently using an external charger identical to the one pictured in your link to charge my 3500 mah extended batteries. It says anker battery expert on it and everything. I can also confirm that it works on the stock battery although I only used it once on the stock battery before discharging it to 40% and sticking it in the fridge.

For Li-ion batteries, a 40% charge is around the best capacity at which to store them for longer periods of time. By the nature of the battery technology, this type of battery also able to hold less of a charge over time...whether you use them or not, it's capacity will decrease. Keeping them cold (close to 0°C/32°F) and charged to about 40% will keep the battery from losing much of its full charging capacity--important for when you decide to use it later.

[Q] A Quick Question About Batteries

I was planning on getting the chichitec ones since those are the ones that have been getting the best word. But those batteries are rated at 3.7v while the OEM one is at 3.8v. Would switching between the two types of battery cause any damage to the phone?
Also are 3rd party batteries safe overall?
Sorry for the newb questions its my first android phone and I'm using the hell out of it and my battery can't keep up
In regards to whether switching mAh amounts will cause damage, no. Might just cause slightly inaccurate battery percentage reading.

the voltage diff is minor.... at 100% charge the Li-ion battery is actually all the way up to 4.2v, when its nearly drained the protection circuit protect the battery around 3v and cut off the power, a fully discharged Li-ion battery would be irreversibly damaged
btw i think you meant 3.8v vs 3.7v

Whoops, yeah I meant 3.x posted it this morning before breakfast xD
Anyway, since the voltage wont cause any issues with the phone, would the actual battery? In other words, are 3rd party batteries safe on average?

"Quick" charger?

Can anyone recommend a faster charger? The wall charger still takes upwards of 3-4 hours to charge, was hoping there was something that puts out some more power.
How many amps does the stock charger put out/how much can the phone 'handle'? (Sorry, I've never messed around with circuits and electronics like that, I'm not sure what the correct terms are)...
For example, http://www.amazon.com/Scosche-reVIVE-Dual-Charger-iPad/dp/B003N7NO4Q that car charger has a 2.1a socket, meant to charge the ipad, would that, in theory, charge the sgs2 quicker than a standard car charger, putting out ~1amp?
edit: realized this is better suited for the accessories forum, feel free to move.
I believe the wall charger is the fastest charger that we have available. I could be wrong, but I haven't found anything faster.
If you turn off your phone and throw it on the wall charger, it will charge faster as the phone is not on to use any battery... but thats probably not what you're looking for.
Your best bet would be to buy an extra battery and external charger and just swap the batteries when they are low. Thats what I do, and its much better than keeping your phone plugged in most of the day.
Our phone has an internally set 650 mA charge current limit - adding a beefier charger won't do anything.
It doesn't help that Samsung put in a crippled charger chip in our device with nonadjustable current, instead of using the more capable one already present in the MAX8997...
and even if the phone lets it charge faster, you really dont want a charger that charges too fast. I'm pretty sure that will murder the battery.
Thanks for the answers, all.

This is fine for "emergencies," but swapping batteries will throw off your battery stats.

How would swapping batteries thow off battery stats? It seems like everything resets once you boot up with the new battery, and isn't battery charge read off the raw voltage?
Lithium Ion batteries require a very particular two-step charging procedure. The battery has to be charged at constant current until the voltage rises to 4.2V, and then it needs to be charged at constant voltage (4.2V) until the charge current drops to about 10% of its starting value.
The amount of current allowed in the CC phase is a function of the battery's chemistry and capacity. It's expressed as some multiple or fraction of "C", the capacity of the battery. A 1C charge rate on a 1000mAh battery is 1A. The large LiPo batteries I use for my RC Heli and Airplane fleet will charge at 5C, for some of them this is better than 10A. But Li-Ion batteries usually can't tolerate more than 1C (and they usually charge at half that rate since this makes them last longer).
The harder you push the charge rate, the faster you wear out the battery and the more likely it is to fail. If you exceed the maximum charge rate, the battery is very likely to fail catastrophically (failure = fire). I charge my big LiPo batteries in a fireproof box for this reason.
My advice is, leave the phone's charging circuit alone unless you know what you're doing.

Sure, it reads raw voltage. But the top end and bottom end worsen as the battery ages, and batterystats.bin doesn't know where those values are for a given battery until it's seen them. The system wasn't really designed to take into account the user swapping in multiple batteries.

Huh... I'll let you know in a year how this battery swapping thing goes then. But wouldn't wear be the same on both batteries if I just swap them daily?

I did this with my captivate where I would swap batteries everyday. Much better than charging if you ask me.

Info required about Atrix Anker batteries

How are anker batteries in terms of reliability and can they show correct charge and mah on the phone.Which one from these two anker batteries i should buy.
http://www.amazon.com/Anker-2800mAh-Extended-Battery-Motorola/dp/B005NEHN62/ref=pd_sim_sbs_cps_9
http://www.amazon.com/Anker-1800mAh...G8/ref=sr_1_18?ie=UTF8&qid=1332675613&sr=8-18
The reason i planning to buy a battery is that the Motorola battery is being recognized as only 500mah and doesn't show the charge correctly on the battery indicator and stays on 1% all the time.
Its okay. The battery is good but the cover started to break on me in about a month. Sucked.
Tapatalk makes me wet.....

Thanks for the replay
Can u post some pics of the cover i want to see how it looks on atrix and check the charge-full-design in sys/class/power-supply/battery/charge-full-design
I would recommend this little package Comes with two 1800's and a nice charger... Just make sure you dont abuse the batteries (i had two in my wallet which i would sit on and such and they got messed up). They are good batteries though... I also recommend letting the batteries run dead then popping the other in, then you can charge the dead battery by putting it in the anker charger. You shouldn't ever have to plug your phone in theoretically.

[Q] How to use 2 batteries alternating

I want to use 2 batteries for travelling where I need a lot of juice for GPS.
One battery will be recharged with the S2. The other battery with an Anker wall charger. That's just a plan right now
I would like to know something concerning the best recharging strategy & battery "calibration" if you are using more than one battery:
If you are using only one battery it's quite simple how to calibrate the system.
But if you are using 2 batteries alternating then you can run into trouble, because the system is "calibrated" to the first battery.
That means if you are using battery1 until 0%. The system knows battery empty. I you are putting the 2nd - already recharged with a external wall charger - into the S2 then I wouldthink that the system is confused, because you didn't recharged it internal.
I want to use 2 batteries for travelling where I need a lot of juice for GPS.
So I would use the first battery until 0% and then change to the 2nd which is already recharged and then draining it until 0% and then again recharging.
The other strategy would be drain the first battery until 0%, then using the 2nd until the evening and then recharging both during the night. But I think this strategy will confuse the system.
Hope you understand the problem and I hope someone knows the best solution!
Thank you for your help!

You don't need to calibrate the battery on the s2. The device should fix the percentage by itself. I would not recommend that you drain the battery fully to 0% as i have heard that it could damage the battery and use multiple cycles for the one you drain it. If you're running SiyahKernel you can try to reset the fuel chip in extweaks. Some say that it's a placebo but I seem to think that it works.
Hope that helps you out

You are over complicating this, just change the battery when it's flat and everything is ok.. I have 4 batteries, two Samsung and 2 off ebay, I always have one in the phone (obviously!), one charged in my pocket and one in the desktop charger.. Never have to worry about battery life
Sent from my GT-I9100 using XDA
The batteries should be charged just right if you use the wall charger, however sometimes when you charge in the phone, it might stop at 96% or somewhere around there, sometimes I off the phone and charge, gets it to 100%
You shouldn't worry about calibrating or whatever, new batteries with li-ion battery should be okay without calibration

sounds inconvenient. better get a big battery replacement along with the new back cover
Sorry for upping this thread, but so (as traslate meaning) can you alternate a 1650 mAh stock battery and a 2000 mAh original Samsung battery without the needing of a wipe/recalibration?
Yes.

i've heard that calibrating is just a myth or something.. i have to batteries and i just change them whenever. (idk if that's bad or not), i don't wanna complicate it or something lol
Calibrating is a myth. Charge to 100% and enjoy.
Yes, no problem if you are using the same batteries like original 1650mah, just change the battery when empty and recharge

Again, sorry to bring this thread back to life.. However I was wondering if anyone has had issues with using two batteries and having the "fuel gauge" chip fault on them. On my previous Galaxy S3 the chip that is dedicated to measuring battery stats, as found on many other phones, developed issues. This lead to the phone registering increases in battery percentage while off charger - basically the battery history graph at any given time had a 60% chance of going down and 40% of going up.
Could the use of two batteries caused the "fuel gauge" chip to malfunction?
Maybe temporarily. But charging it to full and/or resetting the fuel gauge running a kernel that supports same fixes that issue easily.

[Q] Maximum charges of batteries bh6x and bh5x

Hello guys
Do you know what is the máximum charge for the bh6x and the bh5x
I wonder if for the bh6x is 4200mV, i'm having a several battery drain and i want to make sure that the battery is in good shape
bh5x is the one that came with my phone and i'm not sure of it's maximum capacity too.
I recently replaced my battery with the same one that came with the phone. Found a relatively cheap OEM on eBay, and I charge it every day (sometimes twice on days with really heavy usage).
IDK the maximum charges, but you can kinda tell when a battery isn't as strong as it once was when it came with the phone.
Then again this is EXACTLY why I want removable batteries on my cell phones and absolutely HATE integrated battery cell phones... (IDC how "cool" the phone looks)
Sent from my GT-I9100 using xda premium
I have both of those and the maximum charge i get on the bh6x is 4200 and the bh5x is 4174
Hope that helps

Thanks. i found out that both charges uo to 4200 but everything depends on the power per hour they can deliver
