[T-Mobile LG G2x] Antigen:
Well, my 3500mA batt and cover arrived today.

My original cover broke where it said 8MPx. **** that.

Turns out this battery is awesome - from what I see within 6 hour use.

I got it charged and being trying to discharge it with heaviest load.

Running, browser over WiFi, playing music, benchmarking and etc.

Compared to my OEM 1500mA batt this 3500mA is a BEAST!

The cover also fitted fine, but it looks kinda cheap (but what would you expect for $10 delivered)

I would really recomend it to anybody!

I love it!

PS will post some pics tom, when I get back home.

Look for item # 270770593394 on ebay. $10 delivered!
[T-Mobile LG G2x] RZJZA80:
Well unlike most others here, I don't use my phone so heavily that I'm always worried about it dropping to zero. I make phone calls, text, and browse the web and Facebook here and there. I don't play any games or anything like that. My main battery drain seems to be widgets and texting at this point.

I guess it all depends, but the repeated recharging will loosen the plug gap and that's a very valid point. I will probably get the 3500 or 4500 or whatever it is and try it out either way.
[T-Mobile LG G2x] dkb218:
During a normal day, I wouldn't need something this big but for those times I want to hang on the beach all day, this is perfect! I had one for me G1 and that thing lasted all day with extremely heavy use.

Gonna order one.
[T-Mobile LG G2x] pbcal:
I will not take a chance on that. No temperature sensor, no over-charge protection, High amp charger may melt the better inside your phone. If that happens don't forget to post some photos (just kidding:D).
[T-Mobile LG G2x] corrupt05:
ya, guess thats a valid point.. no can do, I canceled my insurance on my phone a couple months ago..
[T-Mobile LG G2x] jboxer:
Anyone having GPS issues with this battery and rear cover setup? I just discovered today with this battery and cover my GPS cannot see any satellites. After putting back in the stock battery and cover the GPS worked again. I examined the stock back very carefully and it appears there may be very small and fine metal connections on the sides and the metal strip that says Google is the GPS antenna; not decorative as people thought. I had another phone with a metal battery cover and the entire cover was the GPS antenna.

Also, the phony temp sensor started to become a worry. The phone would get hot occasionally and the stupid battery temp sensor still said 25 degrees C. It never waivered from 24.8 to 25.0 C. When I put the real LG battery back the working temp sensor showed the phone was closer to 35 degrees C and never runs cooler than 30 degrees C.
[T-Mobile LG G2x] pbcal:
I just tried the ebay fat battery with rear cover and my GPS worked fine. No problem.

And yes, I always told people not to charge the battery over night, since it can melt your phone.

I really want to by the expensive $100 battery. But since no one could confirm if it has working temp sensor, I am holding on my purchase.
[T-Mobile LG G2x] sweepstakes:
Really? This is the first i've heard of that. I always charge my phone overnight...

[T-Mobile LG G2x] d12unk13astard:
Getting my 3500mah delivered today can't wait to see what kind of battery life i'm gonna get out of this monster. I've gotten great results with these 3500mah previously on my OG g1,and recently Mytouch 4g(roughly a whole days worth with constant use).

I got the mugen style back battery cover too, cuz that square looking one is corny as hell.
[T-Mobile LG G2x] KRAZYADROIDMASTER:
You should get a whole 12 hours of super heavy use. The most I got was 30+ hours.
[T-Mobile LG G2x] d12unk13astard:
I'll take it, that's double what I got before with heavy use. Besides that, really liking the extra weight and more comfortable holding G2x for long periods of time.
[T-Mobile LG G2x] KRAZYADROIDMASTER:
I use it when I be gone all day. Doing stuff when there are no way to charge it.
[T-Mobile LG G2x] C0dy:
Got my battery today, and I'm pleasantly surprised. It was a lot smaller than I thought it would be, and if feels nice in the hand. Can't comment on battery life yet, I'll be putting that to the test tomorrow.

Although it looks like I got a different design back cover than everybody else. My bad, read through the thread some more.

Sorry for the image quality, the only other camera I have is my 3DS.
[T-Mobile LG G2x] C0dy:
From the time of my last post and until now, I still have 9% with decent usage (games, videos, phone calls, and texting.) I may just use this an my normal battery since the grip is nice. And the battery life, of course.
[T-Mobile LG G2x] d12unk13astard:
+1 i don't mind the extra heft to the device and think it's a bit easier to hold now. People at my work were tripping out over how it looked but they said they'd rather have more battery life out of their g2x's as well. It was funny seeing them carry their charger to work lol
[T-Mobile LG G2x] whoisloon:
I just got the battery yesterday and I love it!

One question though.. does this battery run cooler than the stock? Seems like it doesn't get as hot..
[T-Mobile LG G2x] jboxer:
It has a phony battery temperature sensor. It will only show values between 24.8 and 25.2 degrees Celsius or Fahrenheit equivalent. That is my only criticism of these batteries as the device has no way to know if the battery is overheating during charging, which could lead to disastrous results if your battery overheats. Since the battery has more surface area it can dissipate heat a little better, so maybe it runs cooler, but you cannot go by any battery temperature readings on your phone.
[T-Mobile LG G2x] whoisloon:
Oh ok! Thanks JB~!!!
[T-Mobile LG G2x] KRAZYADROIDMASTER:
I wish the temp sensor worked.
[T-Mobile LG G2x] jboxer:
So does everyone who owns this thing. I stopped using mine because when I use it my GPS doesn't work. With stock battery GPS works. Anyone in Thailand want to buy mine? Like new.
[T-Mobile LG G2x] lotherius:
Very odd that the GPS would quit.... interference? I have one on the way from Hong Kong myself, should be here in a week or so.
[T-Mobile LG G2x] davjan:
I have no problem with this battery, gps works fine
[T-Mobile LG G2x] J-C.Martin:
Cradle?

OK, Just bought one....

So bad I decided to do that AFTER I just received a desktop cradle for my G2x.

Does anyone know of a desk cradle that can hold the phone with this battery?
[T-Mobile LG G2x] Zenroy:
I do not know of any desk cradles that will fit this extended battery :-(

Regardless, how is the battery life with it?! I'm interested in buying one of my own.
[T-Mobile LG G2x] SpaceRanger69:
To those who have bought these extended batteries, what case do you use or are you sacrificing the case for extended battery life?
[T-Mobile LG G2x] lotherius:
Case? Case? We don't need no steenkin' case!

(ref: http://en.wikipedia.org/wiki/Stinking_badges)
[T-Mobile LG G2x] SpaceRanger69:
Ok.. that made me giggle.. :) Pretty much what I expected though. Looking at the cases around, they are all for the stock battery.
[T-Mobile LG G2x] audiokaos:
I'm using a case from an Optimus One. You need to stretch it a bit, but it fits, albeit tightly.
[T-Mobile LG G2x] SpaceRanger69:
Thanks.. I'll look into it!
[T-Mobile LG G2x] lotherius:
Seriously, though, I kept the Momax case I'd gotten with the Momax extended battery for my Vibrant, thinking I could use it. Won't fit. This thing's a beast compared to the Momax. It However due to the soft-touch it honestly feels better than the cheap plastic back the Momax batteries had.
[T-Mobile LG G2x] chinh_tran:
Is a hard case or a soft gel case? Did you have to make any mod to the case for the holes?
[T-Mobile LG G2x] KRAZYADROIDMASTER:
Can we get a picture to see how it looks on the phone.

Thanks in advance.
[T-Mobile LG G2x] C0dy:
I have an issue with my extended battery. When I leave it to charge, it says it's at 100 percent, but when I unplug it, it does the shutting down process. Tested on CM7 and Weapon just to confirm, same thing happens. Any suggestions?
[T-Mobile LG G2x] lotherius:
Sounds like a bum battery.
[T-Mobile LG G2x] C0dy:
Oh, damn. I'll just get a new one, they're only about $10.
[T-Mobile LG G2x] lotherius:
When I used to be a PDA tech agent at TMO, you'd be surprised how often a bad battery would cause freeze/shutdown issues. 99% of the time the customer would insist on a replacement phone, and would state "yeah I tried my wife's battery" just because they were *certain* it wasn't the battery. Then they would call back later still having the same problem and we'd replace the battery, which would fix it. Except then they'd have a refurb phone that they wouldn't have it they'd just tried a new battery in the first place.
[T-Mobile LG G2x] Liqourish:
So who has have used this battery the longest?. Im too skeptical about price and the heart of my phone frying over time hah.
[T-Mobile LG G2x] Spitfire:
I haven't used it for long but it works pretty well for when I did. It makes the phone too fat for my liking and I don't use it enough to require that much juice on most days. I will keep it for when I travel though, or if I know I'm going to need a lot of battery. Certainly worth 10 bucks!
[T-Mobile LG G2x] chinh_tran:
Definitely worth it. I can go a whole day on it. Doing mainly browsing, playing some games and text and talk. Just wish there is a good case for it. I don't mind the extra heft.
[T-Mobile LG G2x] C0dy:
Hmmm....my extended battery works just fine now ever since I've flashed Tsugi. Really odd.
[T-Mobile LG G2x] lotherius:
I've been at the coffee shop listening to podcasts and surfing wifi for 3 hours and have only dropped to 83‰ battery. Definitely was worth the 10 bux if anyone else thinking about it. Pull the trigger and get the battery.
[T-Mobile LG G2x] BlazinHitman:
Really? A tv remote and a police scanner? I never knew you could do that with this phone. What apps do you got for that?
[T-Mobile LG G2x] SpaceRanger69:
This is the Police Scanner I use:

Any chance of getting a picture of the phone in the case? Any modifications needed to accommodate all the "holes" on the GX2?
[T-Mobile LG G2x] monkeyboywa:
you have a few options..but if your running a htpc you can use myRemote. winmo has the ability to hook up xbox live with metro (which is now being pushed to xbox's around the world) so that'll be another way.

I use mine alot and works pretty good. I'll lose wifi sync sometimes so it freezes up the app..but it's only a minor inconvenience. I highly recommend it (no..i'm not paid or affiliated with that app..just really like it)
[T-Mobile LG G2x] BlazinHitman:
sorry for noob question but im not sure if my phone is 'htpc' or not or how to even find out...lol, does this enable the infrared function in the phone or something????
[T-Mobile LG G2x] Jeasme:
I think it looks so bad :/
[T-Mobile LG G2x] panowolf:
Welp, ordered one of these last night. Got one that is x2 batteries, x2 covers and the wall charger. Expected to be here around Thursday, Will post a few days after that with performance results.

Here lately I have been using my phone at work and we are very slow. So I end up getting maybe 4-5 hours out of my stock battery before I have to recharge it. And this isn't with super heavy use, but inside the building I have very low signal and it causes my phone to struggle to keep signal.

I look forward to seeing the difference between the two.

To anyone reading this thread:

If you are to worried about the size of these extended batteries and prefer to keep your sleek and stylish design then leave this thread.

If you are tired of having to carry your charger with you everyday because you text and few times and the next time you look at your phone its dead.... Buy these.

Well, now we wait for this "BEAST" as others have called it and put it to the test! talk to you soon :D
[T-Mobile LG G2x] ttabbal:
While it worked, I liked the battery. However, mine died on me. Full charge, the phone shut itself off completely and wouldn't come back on. It also doesn't read as charged in a charger. I suspect the little circuit board fried. The cells look ok. If I get time, I'll try swapping the board out with one from another battery, they look to all use the same one.

I was lucky, I kept the stock battery and cover in my laptop bag and had it with me when it happened. So I didn't lose my phone for a day.
[T-Mobile LG G2x] Spitfire:
How long did you have it when that happened? I used mine for less than a week and put the stock back in for looks, but I plan on using the extended one for travel. Maybe I'll keep the stock one handy when I travel just in case.
[T-Mobile LG G2x] d12unk13astard:
I've had my 3500 mah battery for about 2 months now and I always get at least double the juice my stock OEM battery gave me( roughly 4-6 hrs) that's with extremely heavy use,calling texting,gaming,browsing,I'm always on my phone its like become a part of my left or right hand lol. So ya about 8-12 hrs on my extended battery, but if I wasn't such an app junkie I'm sure I could get 24-30hrs b4 a charge was needed.
[T-Mobile LG G2x] panowolf:
Received my 3500mah Batteries today!

In the process of draining one of them to set calibration on my phone.

So far I am quite impressed. I have been stress Testing the CPU/GPU for about 1 hour now and it has only dropped 5%. I look forward to seeing some results in the next couple of days.

Will keep posted. ;)
[T-Mobile LG G2x] KRAZYADROIDMASTER:
Glad to see everyone is having, Good luck with these batteries.
[T-Mobile LG G2x] lotherius:
It's awesome. The only thing is charging takes FOREVER.... wish I had an external charger at this point.
[T-Mobile LG G2x] KRAZYADROIDMASTER:
It does take forever. You need a external charger.
[T-Mobile LG G2x] panowolf:
That and I wish i could find a Soft rubber case that would fit it. I don't like the phone itself being exposed.

Update: I received my Batteries+Backing plates+WallCharger @ about 10:30am yesterday. I put one battery in the phone and the other on the wall charger. Both batteries were around 40% out-of-the-box, and the wall charger charging the battery @ 350mA finished first *Took 7 hours to charge Both.

I unplugged the phone and removed the battery from the wall charger, Re-calibrated my batt-stats and used the phone for about 2 hours *HEAVY use* And the battery was only down to 91%. I left the phone off the charger all night, checked this morning and it had only dropped 2% which left me with 89% After 2 hours of use and 11 hours of Idle time.

Will run the test once more on the 3500mah Battery and then stick the stock 1500mah Back in and run the same test.

[T-Mobile LG G2x] santizinho:
Appreciate the tests this will definitely help. I've been waiting for mine for the past couple of weeks. Can't wait to get it!
[T-Mobile LG G2x] petteyg359:
Is there a cover that fits these extended batteries but also has a cover for the camera lens? More power is great, but I don't want to have to trade a scratched lens for it...
[T-Mobile LG G2x] erupe:
sick

phone looks so much sicker with 100% brightness. Currently getting about 6 hours with a new miui ROM and I'm definitely switching over to a bigger battery. Thanks for posting these results.
[T-Mobile LG G2x] Shaddy-Z.:
Will update with my results, ordered the combo pack deal last night.
[T-Mobile LG G2x] AlicetheBrit:
I just received my combo pack yesterday when I got back from vacation

I got this one "eBay item:2x NEW LG P990 OPTIMUS 2X G2X 3500mAh Extended Battery + Charger + 2x back doors (#320797336748)"

Put one in the charger and one into my phone - changed the mAh on the battery widget to 3500 .. it ws 15 21% - an hour and 45 mins later - it is still at 21% ...

I must admit it feels nice in my hand (nice smooth back) but it feels naked without the protective rubberized case (I had the Trident Aegis Red case) - I am now deperately googling to see if there is a rubberized case out there to put over this to protect the FRONT/LCD should it accidentally fall!

Alice the Brit,

in sunny but chilly today Florida :)

who wishes there was someone near here in Palm Beach County that was a pro at rooting G2x's because I am a newbie/rookie and too afraid to jump into those waters alone !!!!
[T-Mobile LG G2x] Evofusion:
How long does shipping take? Me and my friend are going half and half to get the combo pack but im dying to get one of these since i game a lot on my phone!

Thanks
[T-Mobile LG G2x] lawdawg45238:
FWIW .... there is a thread titled " new G2X case" that discusses a new case with a belt clip. I already had that case and then ordered these batteries. I found that with the extended battery and new case back, the other case won't work, but the belt clip will hold the phone. So you won't have a case around the phone .. but if you are looking for a belt clip, that may be a viable option. That case / belt clip set also comes with a nice screen protector.

Like I said... FWIW...
[T-Mobile LG G2x] Shaddy-Z.:
So got my battery yesterday got here in about 3 days. Battery drained a little faster than expected, I'm at about 9.5 hours and 55%. Didn't use the phone much at all. But I just flashed this ROM today on my brand new replacement G2x so everything is on day one right now. The battery probably isn't fully conditioned, so I will report back. The phone feels great in hand though and the extra heft isn't really all that much. I actually like the phone more now. Its about the same size as my girlfriends iphone in a commuter otterbox.
[T-Mobile LG G2x] petteyg359:
I bought the battery/cover/charger set on eBay (#320797336748), and it works great (after full charge, lasted just over 24 hours sitting on my desk with wifi on, and some light usage). One thing I'm not sure about is what voltage it should be. It gets to ~4.2V on full charge, but as it drains, the phone doesn't show 0% until the battery is down to 3.5V and under. I thought Li-Ion batteries were supposed to stop discharging right at 3.7V...

(Voltages reported by "Darshan Computing" Battery Indicator)
[T-Mobile LG G2x] jeremyritzmann:
Just ordered the 2x 3500 set from ebay. Excited to see how these hold up.
[T-Mobile LG G2x] lotherius:
If anyone is hesitating in pulling the trigger on this battery, let me instruct you:

Do it.

Attached is my current battery stat using this 3500mah extended battery, MIUI and Trinity "ELPMax Battery Safer" kernel.

You'll see I'm still at 70% battery, but I haven't been plugged in for over 15 hours.

As you can see from the app stats, I'm doing nothing super-special to get decent battery life. I made several calls, I have a lot of apps loaded, etc.
[T-Mobile LG G2x] Core Memory:
Lotherius,

Where did you buy the battery from and what battery monitor app are you using?
[T-Mobile LG G2x] NekoNyapii:
Well miui with elp kernal itself already saves a lot of battery I don't think it has to do much with the battery.
[T-Mobile LG G2x] lotherius:
That's the built-in battery monitor from MIUI. I have a couple of others but on MIUI you get great battery info. You have to enable it in the battery settings to get full info.

My battery is the same as most on this thread, http://www.ebay.com/itm/250912593906

I get good battery life with the stock battery as well using this combination, but not rated in the terms of DAYS of use.
[T-Mobile LG G2x] Scott Kilau:
I also bought the 2x 3500 batteries from the Chicago seller this week:

2x NEW LG P990 OPTIMUS 2X G2X 3500mAh Extended Battery + Charger + 2x back doors

(Item number:	320797336748)

I go on long hiking trails and really like to map out the whole path using GPS and a exercise application.

With GPS on and being polled every 10 seconds, the stock battery would be completely drained in about 4-5 hours.

This was just unacceptable to me, so I wanted to get bigger batteries to be able to map out my hikes a lot longer.

Although I have not been able to test out these new batteries too long yet on my hiking, there is no question they are far better/more capacity than our stock ones.

Judging by my initial tests, it looks like these are going to last at LEAST twice as long.

(Which shouldn't be unexpected, considering 1500 -> 3500)

Also, for general day to day use (no GPS), my first set of tests proved I am getting 2.5 days without charging, versus about a day with the stock battery.

But, like most everyone else here, I was hesitant on buying these, especially off of eBay, considering all the bad things you hear about, where the batteries are bogus, or given incorrect values.

As far as I can tell so far, these batteries are "for real" and offer the expected boost in battery time, and are going to give me the extra juice/time I need.

PS: I still am not sold on the extra depth of the new back of the phone to handle the bigger battery, but I think in time, I will end up getting used to it.
[T-Mobile LG G2x] Core Memory:
I ordered the same batteries, etc., as you this afternoon on ebay from the dealer in Chicago.
[T-Mobile LG G2x] lotherius:
The only thing to keep in mind with these extended batteries is this:

They DO NOT have a temperature sensor!

What this means is, if you're heavily overclocking your phone, then it is possible it could overheat and lock up without any warning if it gets too hot. The temperature reading in Android when using these batteries does not reflect the TRUE temperature.

That said, I have not noticed that they get any HOTTER than normal - in fact mine seems to run cooler than stock by feel. Just you will not get any overheat warnings.
[T-Mobile LG G2x] jeremyritzmann:
Apparently the Chicago seller is a quick shipper. I ordered on Friday and tracking shows delivery today. Not bad.
[T-Mobile LG G2x] jeremyritzmann:
Has anyone "prettied" up this hideous backs yet? I'm planning on trying something when I get them today, seeing as I have two :-), but don't to reinvent the wheel if someone's got a tried and true plan.
[T-Mobile LG G2x] steven1193:
Yeah an extended battery is needed for me with my ridiculous battery life. The phone is on 5% and this is from a full charge.
[T-Mobile LG G2x] steven1193:
Woops i forgot to attach the screen shot.
[T-Mobile LG G2x] lotherius:
Where you playing shadowgun or something???

Unless you're doing something to keep both the screen and the processor constantly active, you should be getting MUCH better battery life than that...

If you weren't actively using the phone, then you've got a rogue app using up resources. I highly suggest you get Watchdog or System Panel and start tracking app CPU time to see what's using up all your power.
[T-Mobile LG G2x] jeremyritzmann:
.....or his battery is fried.
[T-Mobile LG G2x] khanggle:
I'm looking to pick up this extended battery off amazon.ca it appears to be the same one as the ebay with a different cover, can anyone confirm?
