"Gold Business Batteries" for the G2/Desire Z Review - G2 and Desire Z Accessories

My wife and I have both had t-mobile g2's for almost 2 years now. I had wanted to get addition batteries or replacement higher capacity batteries for a while. There were plenty of cheap batteries on ebay that claimed 1500 or 1600 mAh that would theoretically be an upgrade over a stock battery but it would be a relatively small upgrade and might not even really be an upgrade if they didn't actually live up to their advertised capacity so I had been procrastinating doing anything. Two things changed and I finally stopped procrastinating. First we decided we were going to keep our g2's for about another year. Second I noticed a number of Gold Business Batteries showing up on ebay at a relatively cheap price. They claimed a really high 2450mAh which I figured was not realistic but even if it fell well short of that it should still be a good upgrade. You can find them on ebay with a search for Desire Z gold battery. Can't post a link yet =)
Ordering and shipping was pretty much what you'd expect for cheap ebay purchases from china. The description was poor and communication with the seller was in broken English but I had no major issues. I just selected the cheapest seller at the time and I'm not even sure if that seller is still selling the batteries now. Shipping was predictably slow and packaging was minimal but everything arrived undamaged and is working fine.
The batteries seem to be a little tighter fit than the OEM batteries which seems to be a common complaint about these replacement batteries. I suspect that they would fit better if you removed the "gold" label as it seems to be somewhat stiff and thick for a label but I haven't tried that yet.
No surprise but the batteries don't seem to live up to their claimed capacity. I installed a battery monitor app and ran several full cycles on my battery and it came up with a measured capacity of ~1850mAh. I haven't tried to do the same on my wife's battery but it is enough of an improvement over our original OEM batteries that it is easily noticeable and she has commented on it and prefers the new battery. We got a charger with one of the batteries so she could easily swap batteries rather than charging the battery in the phone but she prefers to charge the gold battery and not swap back to the OEM battery unless she has to. My impression is the same. The new battery definitely lasts longer and was a nice improvement.
I no longer have the battery monitor installed (flashed to a CM9 Mod now) but after a couple months of use I subjectively haven't noticed a large drop in performance for the batteries.
Short review-
Good capacity cheap battery that doesn't require a replacement battery cover and I'd recommend them or by another in the future.

THX for your return man

I agree with OP's assessment. Definitely better than stock. I also notice that they get a lot less HOT than stock battery, which often felt like it would burn a hole in my pants. This battery produces no significant heat. Key word is "significant" since it is obviously impossible to produce NO heat. I suspect that the increased capacity compared to stock is due to much less energy lost as heat.

Just ordered a 2680mah one. Will report back when tested. With any luck it'll come before the weekend as my trip to London will be a good test.

Mugen 4500mAh Extended Battery for G2X

Look what I found on Mugen's international site. Of course it has a new back cover for the phone because the battery is so chubby. But 4500mAh, dang!
http://www.mugen-power-batteries.co...tery-for-lg-optimus-2x-p990-t-mobile-g2x.html
thanks for the link but NO WAY! $100+ is way to rich for my blood...
i just ordered 2 of these. i like the idea plus they are solar and charge all my gadgets on top of my phone. and shipping from china is 22 for dhl but they are worth it and are the size or smaller than our phone! holds almost twice the charge with multiple voltages including 3.7v which is ours.
Total was around $52 after shipping but just sell one or keep the other for twice as much! ill repost this link in thread.

Too expensive and UGLY
Wow, out if my budget.
I could buy 3 external batteries including shipping, for that.
Sent from my LG-P999 using XDA Premium App
look at the back cover on that thing and then the shape of the batter! what a waste of space!
I am sorry but I get plenty of juice out of my battery, i dont know what i would do with a battery twice the size let alone three times the size of my current one... that **** would last all week without needing a recharge!
honestly for the same price, little bigger and more juice i could just lug around a mini nuclear reactor... where is tony stark when you need him? im trying to hook my phone up with that mini arc reactor bro!
Yeah, that is way too bulky for the size. If they wanted to extend the back of it, why wouldnt they make the battery a sort of P shape that extends further up the back so it doesnt have to bulge as much?
I MIGHT buy a battery that only makes the back case flush with the camera. I already dont like that camera hump on the back, so a battery that only needed to extend that much or a tiny bit more would be perfect. Maybe like a 2500mAh?
Thread cleanup, back on topic please.
My question here is this: Is it completely safe to use this battery?
I'm thinking perhaps in the future I might want to buy one because I deplete my battery extremely fast with constant use. The only thing I'm worried about is if it will hurt my phone in any way.

you know I was thinking this too, but I did watch some reviews on youtube on their other 4500 mah extended batteries for other android phone models. It doesn't look that bad, infact it seems to make the phones look like a tiny miniature powerhouse PCs from the future.
Right now it says their sold out and will get new stock in June, I'm definitley gonna get one. If like the reviews say that some people don't have to charge this extended battery after 3 days of heavy use then I'll be in G2x heaven. Infact, I would bet as LG was in the design proces for the phone that they were shooting for a phone that could last for 3-5 days on one battery charge, but since marketing research thinks consumers will only buy a slim form factor cell phone, they opted to cut corners on performance for cosmetics, which absolutley sucks in my opinion.
just ordered it. Will post a review once I receive it.
I ordered the 4800 one for my atrix as well. I just received that one today. Will try it out when I get home!

Right on, can't wait for the review. Just wanted to ask though, I saw that they were out of stock and that they'd get more in stock and if I ordered on that certain day I looked on the site, I would get it on June 3rd. I looked at the site again and it said if I ordered that day I'd get it on the 10th, now I checked again today and it said if I ordered I'd get it on the 6th. What gives with all the different ship dates?
You also said you just got the 4800 for your Atrix.
When did you order that one and how long did it take for you to recieve it?
How was it shipped out to you, UPS or USPS?
How did you purchase, with credit card or paypal?
How professional are they and quality of the product?
Does the product come with a specific charger?
And how long did your Atrix last on standard battery and how long does the Mugen battery last?
Sorry for the questions, I'm just very interested in this battery and I'm so ready to purchase, just waiting till they get it in stock, before I ordered, although I'm so anxious just to put in the order now and wait for them to ship it out to me on the proposed date a couple weeks later. But is that wise?

Check the forums for an easy to build tester. I tested a few, and stock batteries for g2 and vibrant, none of the extended ones lived up to their claims. They had more capacity, but not what they claimed, and some caused instability. Stock oem tested within 5%. Extended varied wildly, best being about 25% shy of stated. Imo, that's false advertising at best.
I still have the tester set up. Ship me a battery and I'll test it for you if you like. I'll even pay to ship it back to you, but I will post about it here if you do. Personally, I'm not wasting any more money on them for myself.

I ordered it on 5/13 and received it on 5/20

Came via USPS

I used paypal. Had no issues
How professional are they and quality of the product?
The quality of the product is awesome. At least so far. This is my second Mugen battery. I had one for the nexus one as well. worked just fine. The one for the atrix ROCKS right now. On average usage (with stock battery) I would get about 1.5 days. With the Mugen, I hit 3 days with 1 full charge under the same usage pattern
Does the product come with a specific charger?
Nope. Just the battery and the back cover.
And how long did your Atrix last on standard battery and how long does the Mugen battery last?
1.5 days vs. 3 days

By the way, I had a Milestone as well, which also had an extended battery but from Seidio, and that battery i was NOT happy with. Did not add anything in addition to the stock.
The only way to test a battery is using an external load / voltmeter jig. Based on my past experience with Mugen, their 4500mAh battery will test out much lower, my bet is somewhere around 3400mAh. Just enough to make you feel like you got value for your money. Theres no way the average consumer can compare battery life using the phone itself.

Yup you're right. I do not have a voltmeter handy so I'm just relaying my observations.
So far, it's been good (I'm still talking about the Mugen Atrix battery since I haven't reeived the G2x one yet). Far better than the stock battery (not just by a couple of hours but by days) so I'm happy

I'll pay a hundred bucks to get at least 2-3 days on one charge. Anything to get rid of this miserable battery life that makes you feel anxiety when you're away from an outlet, especially if you use the G2x like I do which is on the internet constantly browsing and watching vids and playing vid games.
Although on another note, auto airplane mode does indeed make the phone somewhat viable and stops the drastic bleeding when the phone is not being used, and I also notice that under settings> accounts & sync> background data turned off also helps very much with the horrible battery drain when on standby.
Tmobile has sent me a replacement battery which I had to pay $10 shipping, so I might recieve it on the 3rd of June, I'll hold off on the Mugen 4500 mah and see how the replacement from tmobile goes and play around with the other settings I just mentioned. I just don't like the idea of switching out the batteries each time. Gonna put wear and tear on the battery cover and all, so even though I have an extra battery, I'm still considering the Mugen extended.

I know exactly what you mean! That is the reason I was willing to spend $100+ on a battery because I didn't want to bother carrying extra batteries all the time or swapping them out or worry about charging each one..
I have one, lasts me 3+ days and don't have to swap anything.
Might not be ideal for most people, might be heavy but hey... it's perfect for me
Without a doubt, there is value in having a battery that can last 2 or 3 days. I've purchased large capacity batteries from Mugen and Seidio, and happily used them.
But, for the price paid for these batteries, I also expected to get what was advertised in terms of mAh rating. It irritates me that these companies feel that they can just print whatever inflated rating they want on these batteries and there is no consequence for them.
Heres what I've determined: High quality OEM batteries I've used in the last 4 years all have been around 1500mAh, as that seems to be the sweet spot in terms of size vs capacity for a phone manufacturer. Mugen & Seidio use cheaper cells, typically 1200mAh for the same physical dimensions as the OEM cell. From there, its simple math, 2 cells equals 2400mAh (not the 3000mAh stamped on the sticker. My guess, without even looking at a picture, is that the Mugen 4500mAh battery is a 3 cell unit with a real capacity of 3600mAh.
3600mAh is not a bad setup, I'd throw $100 for it. But I'd still be irritated.
What would be really nice is the manufacturer giving us the option of buying another cell, the stock oem battery with a replacement back that had a charge balance circuit and anything else it would need to be reliable. Known good cells, just an extra one.

[Q] Anybody bought Extended Slim Battery 1980 mAh

Hello Everybody
I am looking to buying the following battery
http://www.ebay.com/itm/LG-G2X-Opti...ccessories&hash=item2eb6f543db#ht_2178wt_1270
I don't want to sacrifice the sleek look of my mobile phone by buying 1350 mAh or 1450 mAh huge batteries.
Anybody bought these kind of batteries already ?
Do you find noticeable difference in run-time ?
That's the one I saw on ebay.
The thing I notice that the slim batteries that are larger in capacity than the stock batteries are more in price than the larger capacity and fatter batteries with a bigger back cover.
I wonder what is that???
I going to order next payday to try it out.
If you get it before I do. Let me know how it worked out for you.
Sent from my LG-P999 using XDA Premium App
I do not think this is going to be any better than stock battery. Better to go with the fat one. You will at least get 2000 to 2200 mAh out of those for $10.
I have had that Andida battery for a couple of months now. Never any problems with it, and I would say I probably get somewhere between 30 minutes-2 hours extra charge over the stock battery, depending on what kind of usage, obviously. It feels noticeably thicker/denser than the stock battery. It fits inside with the normal cover, but you can tell it's a tighter fit. I also charge it sometimes on the spare port of my desk dock, and it's a tighter fit there, as well. And a bit heavier.
I won't make any claims of whether it's actuallyt 1980 or not...but it's a good battery...at least mine has been good to me. Nothing "night and day" that you're gonna convert religions over, but if you're looking for a second battery anyway, it's definitely worth it.
Generally, it's seemed like people with the Andida 1980 mAh battery have gotten an extra hour or two more over the OEM.
Buy it from here instead, only $9.

Thanks for posting that obostore link...when I clicked the OP's ebay link, I was pretty sure I didn't pay anything near $29, but it's been a while and I"ve bought so many things, I couldn't remember...but it didn't feel right.
$9 from obostore sounds about right...I've bought about 6 cases and other stuff from them, so they are legit. It does take about 2-3 weeks to reach your door from the time you order, since it comes from Hong Kong.

GALAXY NOTE 4 BATTERY: Too good to pass up??

There aren't any reviews yet so i'm unsure of the quality and legitimacy of the product. What do you guys think?
http://www.amazon.com/dp/B00PJEQ290?psc=1
EDIT: If you look at the (color) section of the amazon page it shows different options. You can buy a single battery for $11.00 USD
or 3 batteries and a charger for $35.00 USD!
I've found a review about the batteries, although these are for the LG G3, I'm guessing they are similar.
http://www.extendedbatteryreview.co...y-combo-with-portable-usb-travel-wall-charger
It has a lifespan of 1 month.
You really should never ever cheap out on a battery. There are tons of garbage quality batteries out there that are totally useless. Buy an original battery or an extended one from a recognized brand. Also the very cheap batteries have a much higher likelihood of running very hot, leaking, or even catching fire in some cases.
I bought some 'cheap' batteries just for the charger. I got caught with a dead battery on my Vivid and had to wait for "the slow boat from China". (ran battery down due to ROM testing and couldn't recharge by phone}
Now this was some years ago and I don't remember company (overseas) or cost.
My SO got a Vivid & will not update and she uses the white batteries as often as the stock black one (she often forgets to plug in.) One stock battery dead.
So your mileage may very. I would not count on only 'after market from across the pond' as my only anything.

Need a trusted source for Genuine original battery

As per title, banggood used to sell them and I have heard gearbest can be dodgy for counterfeit stuff, Are there any trusted sellers where we can get a real original battery?
You are right, it is pretty hard to be sure you are receiving an actual Xiaomi original battery based on just a web page description. Even given multiple batteries that look identical, and then opting for the one with a higher price on the assumption that it really is original, well, that is absolutely not definitive (at least not in my experience--I have been burned a bunch of times like this...). I think the only way is maybe to buy it directly from Xiaomi because I think even bigger China-based retailers (Banggood, DX, Gearbest, etc.) buy merchandise to resell thinking it is actually authentic only to find out it is just a good fake job. I'm not sure how to get around this. Because this is the case, nowadays, I usually just look on Aliexpress, find a vendor with a good rating and a high number of orders, and go with it. This is based on the assumption that actual experiences and word of mouth have led to a high rating and high number of orders, but neither is this a guarantee.
I did recently purchase a second battery for my RN2 on Aliexpress, and it cost a bit less than US$6 including shipping. It seems to perform as well as the original battery. Although you might see BM45 replacement batteries which offer up to 4000 mAh of capacity, the only way to be really sure about this is to use a USB voltage/amperage tracker during charging that also tallies mAh, and then account for nominal USB vs Li-ion voltage, i.e. 5V vs. 3.7V, and an efficiency factor.
Anyway, in the long run, I have probably not answered your question about a source for an original Xioami battery. But I can say my <US$6 one bought on Aliexpress seems to work as well as the original. Good luck with the search!
It's difficult to find a genuine battery and I beware who claim his battery have more mAh than the original one.
So I bought a Nohon battery from AliExpress and I'd say it's a good replacement.
+1 for Nohon battery. Good, after-market battery

LOL. Yeah my ORIGINAL battery looks like a balloon and it's now hard to close the back cover so I did order the Nohon battery. :silly:
I don't think that you can find the real original battery any more. In general, Dragon TT is a good source for parts, but they haven't had them in stock for a while. I ended up getting a Nohon battery (from what's supposed to be their factory store on Ali) and it seems pretty good. The capacity seems to be on par with the original, back when it was new, and it doesn't drop from 100 to 90% as soon as you start using the phone, like the original did. I've only had it for a couple of weeks, though.
Nohon batteries bad design
Hi,
I write just to warn about Nohon battery and their supposed 6 month warranty.
I had a bad experience asking support about a new battery bought through Aliexpress on 2018/09/09. The battery was a BM35 model designed for Mi 4C phone and has a loosen connector as shown in the photo attached. I had some experience with different brand spare batteries, because as we all know it is almost impossible to find original xiaomi batteries and rarely the replaced battery has a capacity similar to the original so it wears out faster, but this is the first time I see such a poor designed connector. I had the original one and other two third-brand BM35 batteries and usually the ribbon connector is a whole part fixed under the battery shoulder, instead the Nohon ribbon wire seems to be a different kind of plastic less flexible and more easy to cut, or simply not well fixed under the battery shoulder and easy to detach. I think this could lead to a potentially dangerous short-circuit of the battery itself and damage the phone too.
Obviously I reported this issue through Aliexpress dispute system directly to Nohon store and even if my battery should have been replaced inside the 6 month warranty, I received a joking reply telling me they would have let me know in a hypothetical future and they never replied anymore to the next message.

Does the quick charge work with this Nohon battery?
It does, the battery charges as quickly as the original one did, at around 2A.

Any suggestions from personal experience on which is the best battery replacement

I just replaced my original battery with a Max Baer high capacity battery at 3600mAh and it's just as bad as my old original battery. It's draining just as fast. I need to purchase another battery so anyone with experience with purchasing any batteries. If you can give me some advice on which one you bought and how well it did would be great cuz I would hate to buy another one after I buy this one, so any advice would be grateful. And theven MaxBeat high capacity battery was even rated higher than at 3600mAh and the original battery was 3200mAh or close to that number. so I would have thought that this max Baer battery would have done pretty good but it's as a right now not holding up to my standards I have to charge it like twice a day. Once again any suggestions would be greatly appreciate it thank you
Never heard of MaxBaer/MaxBeat or whatever it is - is it the same physical size as the original battery? If so, there is no way it can be 3600mAh. I wouldn't touch anything other than RavPower - as far as I'm aware there are no genuine Samsung ones left and Anker has stopped making them. RavPower: https://www.amazon.co.uk/dp/B072N5G4RB
I'm a ZeroLemon fan. Granted it makes the phone larger and people always comment on how large my phone is, though I have used phones as large as Red Bricks for work (Intermec) so it's small by comparison. I don't use the belt clip with it since I have cargo pockets.
Based on my personal experience, StalionĀ® Strength Note 4 Replacement Battery gives a great performance compared to the original for a normal (not extended battery) and sells at a very good price too. Also 4500mah Golden Battery though its performance is the same as a 3220mah Stalion but comes at a cheaper price.
I have got them from eBay.
I have tried Maxbear and powerbear, neither of which are any good in my experience. I also have two from anker and those were good but they're old now. I just this week bought an extended shenMZ 7500 mAh battery but that is not even lasting an entire day so I think it may have been sitting for a while. I think part of the problem may be that some of these batteries have been sitting in a warehouse for a long time unused. Somebody in this thread said that the RavPower batteries are still good. I also hear from another thread that the TQTHL extended 11800mah batteries are good as well. Has anybody bought a battery in the past few months that doesn't suck?
