I know how mah works and I anticipated the higher battery to last longer. I have run into cheap mislabeled batteries in the past. I just downloaded the free Battery Monitor Widget app, but assume it will take me a few days with each battery to get the results to post. Maybe my 3500 mah battery is just defective. Maybe I didn't give my phone enough power cycles to get accurate readings.
[T-Mobile LG G2x] nitrogen618:
Hah, this explains why I need a new battery.

After 2 cycles, my 1500mAh stock battery was recorded around 1200-1230mAh.

Lost 20% of battery charge. O:
[T-Mobile LG G2x] I.R.Chevy:
Just cleared all stats and I'm trying out my stock battery to see what kinda measurement I get then ill go back to the 3500 and start fresh see what kinda comparison I get. Someone with the andida 1980mah should give it a shot too.... might get a real comparison between the cheapos :)

Pin it to Win it.
[T-Mobile LG G2x] I.R.Chevy:
I wish I could only use my phone that much :p I'm an addict lol what battery are you using?

[T-Mobile LG G2x] idbl_fanatic:
Yeah grant it, I was home sick all day yesterday.

That is the one I posted earlier in this post.
[T-Mobile LG G2x] I.R.Chevy:
What kinda battery you rocking?

Hope yer back up and at er. :)

Edit: Trying to measure the stock battery mah to compare it to my 3500mah so I gotta put it through a few cycles but it held up pretty good considering I was running 1.2ghz max and using it almost solid for 9hrs with some games.

.nice..but the case is too ****ed up
[T-Mobile LG G2x] deathskater:
I'm a very heavy user I am constantly using 4G internet browsing, pandora and gaming this 3500 mah on my first charge gave me about 6 hours of non stop use and had around 24% left when I got home. Not sure if this is right well I was using almost max brigtness and 4g all the time..Definetly an improvement to stock but I was expecting a bit tad better ..

Heck I payed 9 bucks including shipping I guess it ain't bad at all...

I tried switching the battery to the 1500mah and Phone wasn't responsive couldnt lock signal and something called process force closed and phone rebooted lol I'm guessing if I would want to switch back to 1500mah I would need to clear cache, Dalvik and wipe battery stats
[T-Mobile LG G2x] I.R.Chevy:
After alot of testing between batteries I found the cheap 3500mah battery was actually only coming in around 2000mah not 3500 so your speculation is correct. You are only actually getting around 33% more juice out of the bohemoth.... I stopped using it and went for multiple "stock" replacements. Swapping batteries > phone on the charger IMO

As for your errors try fixing permissions as well.

[T-Mobile LG G2x] deathskater:
Mine is reporting 3350 mah and im giving it a lot of use and it lasts me throughout all day when stock wouldt last me half a day. I always try to do full cycle charges letting it get to 15-20% before fully charging. Also found out its best to charge with phone off. Battery keeps charging for a while more and performs better through the day. Price vs performance I really cannot complain at all.
[T-Mobile LG G2x] I.R.Chevy:
You must have got a decent battery then. I had mine for 6 months or so until I retired it... not sure what the actual mah rating was when I first got it but now that I have 5 stock sized batteries the two best are sitting at 1730 and 1810 the rest scoring around 1500. I wont go back to the brick. I like my silicone case too much I had a nasty drop without it and now I have one big ugly mark on the corner...

I also use an external wall charger that instead of plugging the phone in and typically get home from work with +/- 40% battery left with moderate/heavy usage and swap it out right away. The smaller the charging/discharging cycles you run the slower the cells will deteriorate.

[T-Mobile LG G2x] Scott Kilau:
This is what I found as well.

I am not positive that we are truly at 3500 (or 3350), but I have no doubt from my trials and testing, that we are at least double the stock (1500) battery.

I am happy with the extended battery, and at the price we paid, definitely worth the money!
[T-Mobile LG G2x] deathskater:
Yeah id say do not pay attention to what battery monitor says or other apps judge it by the use you give it in comparison to stock. Also i was reading the stock battery on g2x was badly designed and it caused glitches on phone and faster battery depletion
[T-Mobile LG G2x] KRAZYADROIDMASTER:
Mine lasted 3x that of the stock battery???
[T-Mobile LG G2x] aaCotyaa:
How long does it normally take to "fully charge" this battery. I'm charging mine for the first time and its only at 75%..... after charging for 11 hours! ????

---------- Post added at 10:49 AM ---------- Previous post was at 10:13 AM ----------

Never mind.... it's at 95% now.
[T-Mobile LG G2x] deathskater:
Its never taken that long to charge for me , though I use my phone to charge I never got a wall charger
[T-Mobile LG G2x] uncochu:
Hows the battery life after a few months? same? Thanks for the review
[T-Mobile LG G2x] rachit_rox:
Hey guys anyone from India have purchased this battery???

I am looking forward to taking the plunge but cannot decide from where to buy...plz help
[T-Mobile LG G2x] Bulletblitz27:
My results and I've had this battery since last November. May be time for a new one? I used it a lot today. Constantly.
[T-Mobile LG G2x] justjackyl:
Generic Battery

I have this same battery. I've had it since May 2012. It took me about 4-6 charge cycles to reach optimal capacity. And I always discharged to <=10%, than charged on a wall dock charger to 100% uninterrupted.

It is now October 2012, and the battery maybe lasts 4 hours longer than the stock LG battery. It used to last twice as long.

These batteries are GENERIC CRAP, but for the price I suppose they are worth it over paying higher prices for an OEM battery, and even than, you need to make sure it's not a fake rip-off with an LG OEM skin on it.

Just my two cents on these generic batteries.
[T-Mobile LG G2x] SpaceRanger69:
Bought my Anker 2800mAh battery back in April of 2012. When I first got the battery, it was pulling close to 44 hours of use before having to be recharged. I was floored with the amount of uptime. 6 Months later, I am now getting 24-32 hours of charge out of the battery. Still a FAR cry from the stock battery that I got, which if I got 12 hours of use it'd be a miracle. I'm VERY pleased with my purchase.
[T-Mobile LG G2x] FatalityBoyZahy:
The 3500mAh battery which I purchased last month isn't lasting as long as it used to. I can't really complain since I only paid $7.00 for it. I'm thinking about buying a new OEM battery, considering the only reason I bought the extended battery was because I had over 500 cycles on my stock battery.
[T-Mobile LG G2x] xBkKx:
I bought two of these just over two weeks ago and one doesn't hold a charge at all anymore and the other lasts 4 hours max. Think I got screwed lol, no word from the seller I bought them from on Ebay >:-<

Sent from my LG-P999
[T-Mobile LG G2x] Bulletblitz27:
EBay is... sketchy, to say the least. Got mine on Amazon.
[T-Mobile LG G2x] justjackyl:
I got mine off amazon and it does still work. I buy almost all my electronic accessories from the seller EforCity. They always take care of me. I have gotten stuff that did not work and they immediately sent a replacement free of charge and no returning of broken one. Also, once the input wire for my FM transmitter broke a month after i received it, and they replaced it as well. Great seller, I always give them 5 Star. Want links?

I've used this battery previously on my old draining wind rom, it lasted about 8 months now before it became worse than the stock lg battery. So many of these guys are selling the exact same one, and I ordered 2 a week ago for replacement. This was the best deal I could find for the 3500 http-www-ebay-ca/itm/320823765438 (its better than buying a bundle pack because you get 2 chargers, covers etc)

Also bought 3 of these www-ebay-ca/itm/120932518632 (cheapest 1350-1800 batt I could find) Sorry can't post links yet.
[T-Mobile LG G2x] Antigen:
I'm glad I found a real Supra fan :)

You also might consider the price of those 2 high capacity batts.

3500ma - $10

4500ma - $90

From what I see the 3500 chinabatt is pretty stable and strong!

No way near my OEM one
[T-Mobile LG G2x] gpmartinson:
thanks

I ordered one this evening.
[T-Mobile LG G2x] jsapp:
As tempted as I was to get the 3500 battery, I can't stand the shape of those style back doors. I ended up breaking down and getting the 4500 because that back door isn't near as bad. Hope it holds up well.
[T-Mobile LG G2x] danz8509:
battery from the us

i found one that ships from the us! i ordered that one off amazon hoping it ships sooner ive had problems with receiving items overseas before, hopefully this 3500 mah is good! i cant justify paying 4 times that for a battery just cause the cover is nicer and its a lil more powerful if anyone is interested here is the link, i will do a review when i get it!

With 40-50 mins of call a day, several txts, moderate wifi usage, 2 hour music (while en route to work) - If I charge it overnight from 8am by 8-9pm I still have around 60-65%

[T-Mobile LG G2x] baka2x:
I just discovered games and they definitely drain the battery. I was originally going to get another oem battery from t-mobile since I've never used non oem batteries with any of my phones, but I don't want 2 limited batteries. Aside from mugen, do you guys have any recommendations?
[T-Mobile LG G2x] danz8509:
other than the name of this topic NO! 3500 and 4500 mAh are the only options
[T-Mobile LG G2x] vn00914361:
So how much is that in total?

Because I found this online

http://www.wirelessground.com/t-mobile-g2x-extended-high-capacity-battery.html

from Monaco, also 3500 mAh

Price is $59.95 (You Save: 40%)

FREE SHIPPING for orders $50+

so it's just $59.95 I guess.

Been hanging around to find a better battery for my dude, but I don't know which one is worth it...
[T-Mobile LG G2x] Hiryuu:
That actually looks just like the eBay & obostore 3500 mAh battery/cover haha. I think it's worth trying out the cheapos for ~$10.

nah, i think you should spring for the sixty dollar one. :cool:
[T-Mobile LG G2x] adevilfish:
doesn't look bad at all imo
[T-Mobile LG G2x] ttabbal:
I have one of these on order. I wanted the back cover to experiment with my own battery design. Willing to bet that real capacity is in the 2200 range.. I'll test it when it gets here, and disassemble it. All the china batteries I have gotten don't bother to remove the labels clearly showing them using 2 1100 cells or similar... Sigh..... And they never have working temp sensors... Pffftttt
[T-Mobile LG G2x] blackerwater:
I just bought mine as well. I hope its not to big. I still wanna keep it in my pocket =-O
[T-Mobile LG G2x] rubicstrue:

[T-Mobile LG G2x] Texan28:
Yea your right...i got an extended battery for my G1 before and it suuuuuuucked....total rip off...i wouldn't mind getting the 4500 for the price just so i KNOW it would work

This ****ing 10 buck bat is freaking awesome.

After several discharges I'm on 44th hour of light use and still have 59% of charge!
[T-Mobile LG G2x] jacob808:
I probably might just get me one if more reviews come back positive. I also have 2 mugen covers so I just might use those instead of the one that ships with this 3500 one.
[T-Mobile LG G2x] danz8509:
does a mugen cover work with the 3500 battery?
[T-Mobile LG G2x] ttabbal:
I grabbed one of these $10 specials on ebay... I bought it for the extended back so I can attempt to fit more cells in there. If it's going to be fat anyway, I might as well try to cram as much in there as I can. :p

I'll give it the same round of testing I gave the Andida... Cells don't show markings under the sticker, but I haven't completely disassembled it yet.

2927 mAh

If this one shows the same performance over time as the others I've tested, I expect another 100 mAh or so after a few cycles. Still... to "only" be over-rated by 500 mAh is a win with these china batteries. I have not tested to see if the temp sensor is intact. Someone running one, grab the battery monitor widget from the market (free) and put the widget on a desktop for a day or so. Tap on the graph to get to battery temp. Is it a straight line or does it change over time like it should? Time to drop this test unit back in the charger. :D

For 2x tested capacity, if it holds up, the $10 price is a steal. I'll know more when I've abused it some more. :D
[T-Mobile LG G2x] Antigen:
It dropped down to 42%, but I was playing fast 5 since my last post.

Btw, temperature sensor on battery is not working/absent
[T-Mobile LG G2x] Xargon321:
also remember that you will not drain 3500 mah out of the battery without killing it it will shut off with a bout 20% capacity left or around 500-700 mah left you cant drain Lithium ions battery to 0v or you will kill them 3v is the lowest they can go without getting damaged and i think the phone stops at about 3.4. i have seen a lot of company's rate their battery's with usable capacity or with actual capacity it gets confusing very fast.
[T-Mobile LG G2x] ttabbal:
BS excuses from over-rating battery sellers. The stock battery tests out to slightly OVER it's rating on g2x and vibrant. As do cells purchased raw. Hell, I've opened batteries that say 3500 and found a pair of cells marked 1100 in there. It tested to 2200 as I would expect. I've worked with a LOT of lithium batteries. And I don't drain them to 0v. That would be stupid. I drop them to 2.9v which is the point most manufacturer datasheets recommend. Unlike the rip-off artists, my tester design is fully documented and my source code posted. See the Vibrant Accessories forum.

If you don't like what I post regarding battery ratings, you either got ripped off and don't want to accept it, or you sell over-rated batteries. lol

The R/C guys don't tolerate this crap, and neither should we.
[T-Mobile LG G2x] danz8509:
so are you talking about the 3500 mah battery? cause in a post before you said it read at 2927 mah?
[T-Mobile LG G2x] Xargon321:
How is this a BS excuse i am a r/c guy and i know about this crap having seen it. im just warning people that china usually rates their batteries for the batteries whole capacity meaning you'll never get 3500 mah out of it without hurting your battery. Most r/c people will tell you not to drain a battery past 20% and that's 3.6-3.7v for LIIon and Lipoly batteries. I know there are people out there out there that are trying to sell you batteries that dont have the capacity that's on the sticker ran into that as well. but dont lump me in with them because i said something you dont like.

Mabey i was not clear and you misunderstood what i said.

Company A produces a 1500 mah battery they label it as one even if it dont put out that much.

Company B Produces a 1500 mah battery they make it a bit bigger so there is 1500 usable capacity.
[T-Mobile LG G2x] ttabbal:
I'm talking about companies vastly over-rating the capacity. Being from china is no excuse as all the manufacturers clearly state real usable capacity, anything over that destroys the battery and they tell you that in the datasheets. Even the ones in china.

I wasn't calling you out, just *****ing about the trend. R/c users have nice computerized chargers that tell you the real capacity. Cell phones generally can't tell you the capacity. So we get more fraud. Imo, useable capacity less then 90% of stated is, imo, fraudulant. For a cell phone battery, room temp at .5C discharge or less is a reasonable test.

As for the particular battery in this thread, looking at the pic in the op, I might have a different one. My label is b/w, the op is in color... I'll post the ebay seller link when I get to a computer. And yes, for $10, ~ 3000 is good capacity, but they should mark it that way. I'm irritated about the temp sensor not working though, it's a good safety feature and it's cheap as hell. There is no good reason not to include it.
[T-Mobile LG G2x] Xargon321:
ok ya we are on the same page i dont like that practice anymore then you do just have to deal with it as best we can. Can you're test rig go above .5c? i would be interested in seeing what the stock battery droops to under load at 1a or above as the g2x can draw that at times and i think some reboots might be attributed to that.
[T-Mobile LG G2x] ttabbal:
That's a good point. I can adjust the resistance, so I will look into trying that. I just have a few 1% power resistors I put in there, then just adjust the code to take that into account. I'm currently draining at about 700mA for a full battery. The idea was to keep close to what the phone pulls, but I have seen it hit about 1A as you mentioned... I'll see about running a test at about 1.2A, that should cover spikes.. Should be about 3.25 ohm... Need to see what size resistors I have on hand. What would be really cool is switching in/out resistors during a test, simulate steady draw + current spikes..... Shouldn't be too hard, an extra resistor+transistor and another output pin on the micro..... lol

I've wondered about the phone drawing more power causing a voltage sag from the battery... It's logging the data to a terminal screen now, I could probably capture the data and run it through gnuplot or similar to see voltage over time...

The battery I purchased is this item on ebay: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=270771439587&ssPageName=STRK:MEWNX:IT

Took 2 weeks to get here, but I expected it to take a while..
[T-Mobile LG G2x] Xargon321:
ya that's the same battery that the obostore has for the same price even. is the battery 2 cells in parallel or just one big cell? its there a way to test what the LVC Chip on the battery is set at?
[T-Mobile LG G2x] jacob808:
It's great to hear opinions from the R/C guys on lithium batteries. I myself did alot of reading up on lithium batteries since I had an electric bike kit, but what I'd like to know is if this 3500mah battery does indeed have a BMS (battery management system) microchip on it, as this is what I read on ebay.

Also, would the Mugen 4500 mAh have a BMS chip as well?
[T-Mobile LG G2x] Xargon321:
i dont think there is a phone battery anymore that dont have a chip in it. it just a fancy circut breaker if you try and over discharge it it cut off the battery if you try and over charge it it cuts off the battery
[T-Mobile LG G2x] blackerwater:
Just got mine today. Took awhile but its not as big as I thought plus it fits in my hand better. So far looks good on my phone.
[T-Mobile LG G2x] jacob808:
I think the bottom part is just as thick as the mugen cover. It's just that mugen chose a better more smooth design for the cover than this monstrosity.
[T-Mobile LG G2x] ttabbal:
It's 2 cells in parallel. I haven't pulled the pcb, nor have I dropped it below 2.9v. The phone kernel won't let you go lower either. To test for the cutoff, we would have to just short a resistor across it and see what it does... It's probably not much lower.
[T-Mobile LG G2x] ttabbal:
looking at pics, the mugen isn't any better or worse looks wise to me. I also doubt their claim of 4500 mah, but I don't have $100 to use checking on them.

If anyone wants to know bad enough, send me one with your address and I'll test then ship it back to you at my expense. Or build/buy a tester, then report here for everyone. :)
[T-Mobile LG G2x] Joe333x:
From the pics i have seen the mugan cover is bigger. Also from my experience with extended battery covers even though the more expensive ones that look better have more hollow space which makes the cover break easier
[T-Mobile LG G2x] gheymann:
Inexpensive extended aftermarket battery provides surprising performance

After hearing and reading about various aftermarket battery horror stories, I’ve generally steered clear of these bargain basement offerings. I ran across this battery thread regarding the extended 3500 mAh aftermarket battery for the Optimus 2X / T-Mobile G2X.

I've followed this thread with interest for several weeks and after receiving generally positive reviews from users, I relented and ordered one.

I’ve been using the extended battery for a few days now and have been very pleased with its performance in comparison with the OEM 1500 mAh battery. My device usage varies but on most days with the OEM battery I’m scrambling for the charger by 5PM. I haven’t changed my usage pattern with the extended battery and my phone has managed to stay between 65-75% charge at the end of the work day.

Are you willing to give up the relatively svelte lines of the Optimus 2X/G2X for the increased performance of the extended battery? Although the cover fits well, its boxy design detracts from the look of the device. The extended battery and cover almost doubles the thickness of the device where the back juts out to accommodate the size of the extended battery. A bonus to the oversize battery cover is that it will now sit up without the need for a stand when placed on its side on a level surface.

I don’t mind the extra size and weight of the phone with the extended battery installed as much as I though I would. There may be times were I know I won’t be away from a charger and choose to use the OEM battery and cover. However, for everyday use I will continue to use the extended battery and cover. The trade-off of size vs. performance is definitely worth it for me.

Kinda wish I'd found this thread last week. I got the Mugen 4500mah battery a few days ago but this would've been a little easier on my wallet.

Oh well. So far I've been very impressed with the Mugen. I just had a run of 64 hours off the charger and there was still 10% left when I plugged it in. I unplugged my phone Sunday morning at 6am and didn't plug it back in until last night (Tuesday) at 10pm. And that was with my normal moderate to heavy usage. Despite the look of the cases, these super life batteries are sweet!!!
[T-Mobile LG G2x] RZJZA80:
Got mine in today. It was at 50% and took two hours or so to charge. After a few hours and a couple texts and brief facebook message, it went down to 88%. Not exactly what I hoped for. Maybe draining it and recharging it will make a difference. Btw I bought mine off Amazon for $18 so returning it wont be an issue.
