Typing on a tablet is no excuse for bad grammar...
Found this using something called Google: http://forum.allaboutcircuits.com/showthread.php?t=71445
I'm not sure in your case since they are only different by .1V, plus we're dealing with rechargeable batteries here...

Might be worth asking in here http://forum.xda-developers.com/showthread.php?t=2239829

I'm sorry I went and just bought a brand new gs3 3.8v 2100mah battery for 16 bucks at a local store . its not worth 16 bucks to fry my phone . cheers .

5 days yeah, im assuming you mean 5 days on standby meaning you barely if ever used it in that time because it is practically impossible otherwise to get that amount of battery for 5 days.

Bang on man! think my worst case I have burned through a whole battery in a 4-5hours (chroot vnc gps etc) you know what though, it's not an iphone carry a spare!!! have a charger, have a battery pack charger, have a car charger!
the slightly more worrying factor for me is the power draw of some apps being greater than the draw on car charge.
I-on road for example probably the only truely useful AR app but V. battery intensive (gps and camera on full time go figure)
Lol - it doesnt matter how many days you got, i bet it was still only 3-4hrs screen on time like everyone else.

Battery question

This has probably been asked a million times but I have searched for an hour and cant seem to find exactly what I am looking for. I reset my battery stats because my battery life has been horrible the last week. My phone now says fully charged but the meter only shows 92. Should I let it die completely and recharge completely and then it will be fixed or will it just do the same thing? I am on ICS passion 10.6 if that makes a differnece. Ill be getting a slim 220o mah battery next week but this is still annoying me. I work 10+ hours a day and text my wife a lot and im only getting 13 hrs on the battery. About 100 texts, 30 min of web and I get auto updates via craigslist notification. GPS and wi-fi are off and my sync settings are for 1 time per day. Thanks all!
13 hours is pretty good. also, read this: https://plus.google.com/u/0/105051985738280261832/posts/FV3LVtdVxPT
I like to use an app called android booster u can go in and see exactly what app is draining the most battery that might help

Did you check out the stickied guide called "[How to] You Want Better Battery Life:::Read This" in the Vibrant Q&A section? There's some really good stuff in there. It won't help in solving your battery only charging to 92% issue, but it should help you get the most out of your battery.
Thanks all, my biggest issue I'd with the meter reading wrong, but I'll check out the better battery life thread, I can always use an improvement!

Try downloading "Battery Calibration" from the Market. When your battery reaches the max charge that you see possible, calibrate it, and reset your phone. Always works for me.

Battery works fine?
So no problems with this battery? I saw an 1800 but this might be better if it works and fits ok.
I should have it tomorrow or wed ill let you know about the fit
In the picture on the link you provided, that battery looks like it has four contacts, not like the Vibrant's three.
Some other pics I found on google images show that might be the case, too.
I am not holding out much hope that this battery will work for you. But if it does, please follow up and let us know.

My 3month old S3 died :(

Wow lastnight i left it on charge and today i wake up phone is total dead.. removed battery 30min nothing no led or anything, charger plugged in total dead.... :crying::crying: how can this happen i havent root or anything its been working perfect as of lastnight....
and my old 1.5 year desire still works rofl..... i should have bought htc.....:silly:
A minute of silence for your beloved S3...
Well, in case you really have a faulty one which is only 3 month old, you have warranty and it will be replaced. Products who are sold by millions are always some defective, electronics.... I had the same with my Sony cyber shot camera.... a few years back. Just go back to the store and get a new one.

I'm not sure about this because he said its the same with the charger plugged in, and it will run with the charger plugged in but no battery.
If you don't have a spare battery to try use a multimeter put the probes across the positive and negative terminals of the battery if there's an output on the screen its fine.
That's if you have a multimeter

Doesn't work, it needs the battery as well.
Maybe the charger is broken? Connect it with your pc
Sent from my GT-I9300 using xda app-developers app
take it back to the store you got it from, ask them to put a battery in it for you to check whether its faulty, they shouldnt have a problem with this. If its still dead then you dont need to worry about the fact you have probably flashed a cooked recovery / rom or rooted, it will be dead, they'll likely just swap it out. - albeit via samsung.

Tried and tested, AOSP is definitely faster on the GS3 and battery lasts longer than stock (depends on your usage) if your not a fan of AOSP and like the Touchwiz wait for the Jellybean update to come.. shouldnt take long now..

No it won't, but these batteries generally overrate their capacities and so the battery life may not be as good as you think.
Even if it is really that capacity it isn't going to harm your phone

The 3Ah battery is included in a phone cover. If is an internal battery is a FAKE!
No, this auxiliary battery do not harm but is not recognized correctly by the phone and need to modify the batt specification.

Battery life? + Roms

Does anyone know a Rom that has a lot of battery life with moderate usage? I've tried a lot, but I would like your inputs on it.
While I'm at it, might as well ask all of you what roms your using? I'm using Viper touch 2.1.4 right now.

I am using Dark Unicorn 2.5.
I was on CM7 for a few weeks, but the ROM was really slow and everything lagged. For instance, when I turned on the screen and unlocked, it took it roughly 5-10 seconds to respond before I could do anything. Other features didn't work, including the Market. I read over 100 posts about this Market issue, and couldn't resolve it. It led me to Dark Unicorn.
Dark Unicorn is insane amazing. Everything works (except720p recording). I have had no bootloops, no random shutoffs, nothing. I am trying to kill the battery as we speak and I cant! I just had the screen on full bright ON all the time, wireless, GPS, bluetooth, and music on for the last 2 hours and it only dropped 20%. I left it on all night with the screen off, 100% charge and it was still 100% in the morning. That includes the Data + Sync being on. On top of it all, I have it clocked at 1.2 right now.
I am thoroughly impressed with this ROM. I cannot gripe because I appreciate the developers work, however, if I had to have one complaint it's that there is no option to turn of haptic feedback for the screen off and on slide. I have disabled it all across the phone, but when unlocking it vibrates.
For anyone who cares, I am using the MDJ Kernel as well.
:good:
Nice I'll try that ROM again! Last time I had some CPU problems, but that was all my fault lol.

There are "oversized" batteries but you have to take off the rear metal plate and you can't use cases designed for the OE phone size specs. The largest I think I've seen was something like 3500 mAh (again, no rear metal plate to hold battery in but they come with an extra one that's extended and holds the larger battery in otherwise it would fall out), largest that actually fits inside the phone was like 1600 mAh. Perfect for playing Ingress but terrible for using as a daily driver.
