[Q] Can I use two batteries in rotation?

My old battery was dying after 10 hours of use. So I bought 2 more batteries. I was wondering how I would use the 2 batteries efficiently and deal with the battery stats.
Should I break in each battery?

Well you'd basically have to re-calibrate each time you switched ; charge to 100% > let it fully discharge > charge back to 100% again, to be truly efficient.

Well, they are identical batteries, so they should discharge at the same rate.
I'm going to try just breaking in both once and i'll post my results.
If anyone has already done two batteries before, please post.

2 identical batteries won't ever be identical. You could get 20 of them, and no 2 would actually be identical. To do it "properly" there is a file that records the battery stats, but I can't remember wtf it is right of the top of my head. What you do is calibrate the 1st battery, then rename the file to whatever.one. Then calibrate the 2nd battery. When you go back to the first battery, change the current file to whatever.two, then change whatever.one to the proper file name.
That said, even though the 2 batteries won't be identical, they will be close enough not to make it worth all that work.

After a month of using this method, I can say it's been GREAT! I can't remember the last time I plugged my phone in to get it charged. =)

not sure if its the best way, but what I do is I have my original battery which I charge within the phone and then I have a 3rd party cheap battery I got. Got a cheap charger for the extra battery and rotate them in use every so often. Seems to get me pretty good battery life, haven't messed with the battery states either.

New battery conditioning

What is the proper way to condition a new battery? I just purchased the Samsung 2100, and want to make sure I use it properly.

Just use it. Lithium batteries do not need to be conditioned or discharged completely or anything like that. Just use and enjoy.

I bought the Anker battery and it says to deplete the battery fully before recharging it back up to 100% without pulling the battery out of the phone...4 times. It may be a bit much but I wanted to make sure I got the most out of the battery. I believe in it because (i bought 2) one doesnt last nearly as long as the other...I properly conditioned one but not the other.

aftermarket batteries need to be condition like, fully drained and fully recharged.
on the other hand oem batteries don't.

Li-ion/Li-polymer batteries do not need to be conditioned. You are only wasting your time, it will make no difference whatsoever to the health of the battery. In fact letting these batteries run down completely can be harmful to them

You could never condition a Li-ion battery but simply calibrating how the OS logs the battery stats.
That's it.

1-You can't condition a li- on battery.
2- If you could, you wouldn't need to condition a manufacturer's battery.
3- fully depleting any battery harms (and could kill) it. That's one reason most devices won't really allow you to drain every bit out of it (cell phones are a prime example)
4- I've had batteries that I 'conditioned' end up weaker than they started out
5- I never stop at #4. 1,2,3,4,5. 1,2,3,4,5. It has to be done 3 or 4 times.... 5 3,4,5 3,4,5 (just kidding)

I agree but why do you think the stock samsung battery would not need this? I mean it does specifically state in the manual to not use until fully charged. I doubt they are just saying that not knowing what they are talking about.
In anycase like almost anyone who buys a nexus I am way to excited to wait for the dam battery to charge.

The charging cycle is only for the firmware to log the battery stats so it's reflected correctly; it has nothing to do with the battery itself. That's why people recommend it for new batteries - OS will be able to reflect the battery level more accurately.
Like it's been repeated gazillion times before, you could not condition a Li-ion battery. It starts to degrade as soon as it leaves the factory NO MATTER WHAT YOU DO and basically dies within 3 years from the manufacturing date.

I guess that's what I meant. Thank you guys for the responses. I charged it fully, then ran it to shutdown, then charged fully again. So far, so good.

bought cheap Chinese 4800mAh battery, works fine

I bought this exact battery on eBay:
http://www.ebay.com/itm/4800mAh-Ext...US_Rechargeable_Batteries&hash=item51a976ade9
It said it only worked with the i9300 Galaxy SIII in the ad, but when I got it, it fit fine into my SCH-I535. I am doing the initial charge on it now. Only problem is not having a pebble blue case but oh well
it seems to be charging much more slowly than the OEM battery but I guess that's to be expected with the higher capacity.

Ballsy. Def post some screen shots. Wanna see how this turns out.
At this point, my phone is just one big tweak.

Seems like a good price. Would love to see some screen shots of battery usage if at all possible.

I bought the one from gorilla gadgets.com that thing is the best $20 I've ever spent. Bought it in September and I still get over 6 hours screen time with almost every charge. You should check it out

here's one I took a few days ago. This battery seems to work better the harder you work it, kinda backwards of what you might think but hey oh well.

Agree. I'm also very impressed with my GG. I am on my 3rd complete cycle and had over 10hrs screen time, (in 2,5 days of use).

Thanks a lot OP for the heads up on this good deal. I just bought myself one as well.
Quick question to people reading, to cycle the battery properly when you get it, you simple charge it to full in your phone, and then discharge it to zero percent. That's once cycle correct? This article I found said that you do that 4-6 times. Is that the correct amount of times?

You may want to re-read the article you linked to. From the link.
Rather, to condition a new Li-ion battery, fully charge it; it should be allowed to charge for 7-8 hours on the first, initial charge. In other words, when you get your new cell phone – and it has a Li-ion battery – allow it to charge for 7-8 hours even if the cell phone claims to be fully charged. (It is preferable to use outlet charger vs car charger or USB charging via computer because of the voltage difference.) After that, there is no reconditioning necessary for Li-ion batteries since they don’t suffer from the “memory effect”. However, be sure to avoid fully draining/discharging the Li-ion battery as much as possible; every time a Li-ion battery is fully discharged, it loses battery power and life

Do you find that the battery drops very quickly from 100% to 90%? And then hovers at 90 for a much longer time?

Thanks for the heads up on that. For some reason, I didn't even see the Li-Ion section, and the parts that I mentioned came from the Nickel-Cadmium section

No I don't think the NFC works, what do you expect for $9.86 shipped from China?
(buy it now price with free shipping: http://www.ebay.com/itm/4800mAh-Ext...214&pid=100011&prg=1005&rk=2&sd=350739453463&)

Any more Screenshots please? I'm mostly interested in Screen on time.
Have other people also bought this battery and can share their impression?

It'll work good for a while, but eventually the battery will last less and less longer, that's been my experience with cheap batteries, but even when the battery does "settle in" and not perform as well as it did in the beginning, it still performs better than stock (In times of battery life, couldn't comment on how safe it is and if it's efficient)

I can see that. After all every battery has a certain amount of battery cycles it can go through. But for me personally that wouldn't be a problem, because if You always cycle through several batteries, then even those very cheap batteries will last the lifetime of the phne.

[Q] Buy a new battery

Hi all!
I use the gadget about 2 years or more. My Battery is very bad... 1.5 hours of screen!
Can you tell me, where i can buy new REALY original battery for this phone. (in US).
Thank you!

I've seen good things about one on Amazon. Which ROM are you using? Also, which kernel?

My guess is a battery issue...not a bad battery tho.
Why not get gsam and post some screenshots after a good long drain?
Your setup, usage and apps have surely changed over time. Something is likely draining your battery.
Read the first 3 posts in the battery thread in my signature.... Its for the N5...but most info is universal.

Ok. I've seen some good things about Anker batteries (like this one:http://www.amazon.com/Replacement-T...H-I515/dp/B0078WL4YO/ref=cm_cr_pr_product_top)
With a new battery, do a full charge, full discharge (until phone dies and will not turn back on), and another full charge.

+1 for the anker 2200mah replacement. It's cheaper than the oem battery. It lacks nfc though. And as for the whole "battery memory" thing, don't worry about it. Just pop the new battery in and use it however. I just bought the anker to replace the original battery in my wife's s2, her battery life has doubled.

I just bought the Anker 2200 mAh battery and its great. My phone does last a little longer on standby, but my screen-on time hasn't increased by very much (I typically get about 3-4 hrs screen time).
I'm running CarbonROM + Wildkernel and other various tweaks for battery life. My phone spends most of its time in deep sleep.
When you open your battery stats, what things are taking the most out of your battery? I've found the app Wakelock Detector to help a lot in tracking down battery drains.
play.google.com/store/apps/details?id=com.uzumapps.wakelockdetector&hl=en

GSAM gives a much easier to understand picture of battery usage. If you're rooted, get Gsam root companion as well to see held awake stats. ?

Fry battery 4000mAh not worth it

[I posted this in the general G3 accessories section too, but in case you didn't see it]
This one:
http://pages.ebay.com/link/?nav=item.view&id=171470554241&alt=web
I get it, it was a long shot, but for ten dollars I figured I'd try. Like I'm sure everyone would assume, this battery does not last as long as stock. I know SOT varies by user, but with the stock LG battery, I consistently got 35 minutes SOT per 10% battery used. With the new battery, it was 26 minutes SOT per 10%battery used.
I followed the instructions of fully discharging until the phone shuts off and then charge to 100% 3 times and still no change.
It's not a bad backup, but it's also not performing like an extra 1000mAh should.

Crap I ordered a similar 3850mah that will probably be the same. Obviously LG thought hard enough about battery size prior to release. Perhaps it could've been 3500 and still stable though.

Someone on Google+ in the G3 community ordered a 3800mAh battery from Hong Kong and he reports he's getting 25% more battery life over stock. So you might be OK. I was going to order the one he did, but got power greedy and found this "4000mAh" one. Sad thing is, they were both about the same price, so there's no easy way to tell if it'll work better or not.

Get the right kernel and mods and your stock battery will last you all day.

I've tried. But without losing out on actual features like Google now always listening, location services and what not, it's not that easy. I didn't buy this phone to not use features, so I was just looking for a larger mAh solution so I don't have to turn off useful features for the sake of battery life.

I bought the TrendOn brand batteries. It was two 3000 mAh batteries and a charger. They perform as well or better than the OEM battery.
