[Q] Ecell - GOLD 2430MAH BATTERY FOR SONY ERICSSON XPERIA PLAY

Has anyone tried this Ecell 2430MAH battery ?
http://www.amazon.co.uk/Ecell-2430M...5?s=electronics&ie=UTF8&qid=1326647685&sr=1-5
Still not even lasting a day with the stock battery. (GTmax one was better).
If this is junk think I will just get the 1800 Mugen Power one.
(I think the performance of the stock battery is horrendous - perhaps I was defrauded by shop I bought it from (One of the staff needed a new one so swapped theirs for mine etc. Never buy from Dial A Phone).

This was posted on my thread for the 2600mha battery. From what I make if it stay away from ecell. Here is the link. This is not from me but from another user on xda. I am simply pasting the link he provided.

I bought a case for my Xperia play from them and it's seriously the best £2.50 I've spent in a long time. I've tried 4 cases ranging from the obscenely expensive to the acceptably cheap and their case is by far the best. Easy clip on, easy take off (though it wont ever come off by accident) and it feels/looks very nice.
Cannot recommend it enough, especially after seeing all the negative reviews for every other case in existence for the play.
HOWEVER - this was my first experience buying from Ecell and all was well and good. Unfortunately, hundreds other people have had DREADFUL experiences with them, ranging from fake sd cards to tampered/used/busted phones being delivered and even negligence towards contemporary buyer/seller code and morals.
http://fotios.org/node/2173
I suggest you visit that link and consider carefully before purchasing the battery. I too was thinking of buying that battery but was turned off by the comments in that link.
If you do decide to buy it, let me know if it's worth it please!
EDIT: LOL jgregoryj1 beat me to it

E-Cell are a bit hit and miss, had some good and bad experiences with them, Looked at that exact battery for my play but just looks too good to be true in my opinion
Brought a case from them and it arrived in 2 days. Great case for the play too
But then again once brought a Motorola Milestone from them which took 3 weeks to arrive and came all in chinese. So like I said, the companies very hit and miss. So you take the chance with anything you buy with them
Saying that, Unlike some other people, I think the stock battery on the play is bloody marvellous. Really appreciate it after the crappy 1230mAH battery I had in my last phone - the HD7. You were lucky to get half a day out of that.

I agree. I love the battery on mine. I can get a full day using whatever I want on whatever brightness I want, using whatever connection utility i want and still have some left over by the time I get to bed. I use tunein radio on it when I go to sleep so it's plugged in all night anyway!

yeah i actually found this link "http://fotios.org/node/2173" whilst looking for other vendors selling that battery after i saw the posts about it in the battery thread. They seem fine with cheap items and bad with anything +100 dollars from what people are saying on that forum.
I ended up getting the mugen 3600 myself, but i thought id post up the link so people here could make their own informed decisions, if anyone does buy it, please post and let us know how it goes, i think alot of people would be keen for a bigger stock battery at that bargain price(if it works).
seems like a gold phone bomb atm to me though

and what do you mean....is there really an improvement of 830mha to the stock batterie?
I also got an gold ecell batterie for my "old" lg optimus speed.
I think i saw an improvement of the battery (1500 mhA Stock to 2430 mhA from Ecell)....
The improvement was ~15-20 % more power i think.

I just bought this 3600 mAh battery off of eBay (http://www.ebay.com/itm/400280170439?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649#ht_2866wt_1139). Does anyone think it's not a good battery?

Nice, and it has an extended cover. I heard I other threads that there wasn't a extended cover. Anyone here tried the e-cell 3600mAh and the cover? Also, is the mAh increase picked up by the phone automatically, or will I have to tweak a build prop?

I have a gt max (?) 3600mah battery and the phone seems to pick up the battery capacity with no problem. Of course, your experience may differ from mine due to differences in batteries.
Sent from my R800i using xda premium

i have also an 3600mha battery for my r800i and the duration icreased to about 50%.
The extended cover is really nice and fits perfectly. the only problem with the extended cover is, that it squeaks.
The extended cover also improve the gameplay with the xperia play because with the thicker back you can play really good with the gamepad.

Even if it doesn't, small price for a spare battery
Try browsing through the ebay feedback for that seller.

I bought this one and it definitely has extended the battery life for me, I can go a whole day of whatsapping and calling my gf without having to charge it at work....

i bought a "2430 mAh" battery from a hong kongese ebay seller and it definitely is not better than the original 1600 mAh, but it only cost 8 euro so whatever...

I bought this one months ago and love it, it is big but it lasts for 2 days.

I had a 1950mha battery in the same size as the stock battery... nothing but bad luck. Phone was on crack. Glitchey and lagging. Then I read that you can cram a higher mha battery inside a stock battery for a phone per se. But then what happens is the battery gets hotter (which that one did) and with the additional heat comes a faster discharge rate, and a overall shorter life span of the battery as it cant stay cool. And with the higher heat will also make your phone hotter

Anyone tried the 2300mAh ebay battery, yet? At $11, I almost want to risk it, but I'd really like to know if anyone else has had experience with it, first. The one I'm currently looking at is eBay item 300832163583 (I'm too new to be able to post links).

Umm... Maybe. It doesn't say "Gold Battery," but it says "Golden Standby Battery."
Apparently, it's made by a Hong Kong company called Kinps. It's very prominently branded, at least in the picture.

Alright, well that makes me feel not quite as uneasy about trying it out. I looked at the ebay feedback, and I only saw a few negatives for the battery as opposed to ten or so positives, so it might be okay.
This one doesn't look gold-colored though; it's white, purple, and orange.

I bought these yellow/red-on-white ones and they are very stable and give some juice to my Play (they're rated @ 3600mAh). For me in a cROM like KXP for XPlay with Turbo Kernel JB/ICS r12 lasts around 2 days at normal use, I really pushed these batteries to the limit (and my Play too btw) by overclocking @ 2GHz playing NFS: Most Wanted (this game is very hard on resources and CPU) and they didn't explode lol
I have them since June 2012 and they're in good shape right now.
You can try them if you like. :good:

Oh, no, I really, really don't want the deeper battery cover. First, I'd lose my beautiful, blue AT&T rear cover, and second, I wouldn't be able to use my dock! Well, not without switching back to the stock battery, anyway. And that kind of defeats the purpose of using the dock as my charger.

Eh, I'm starting to reconsider the extended back thing. Yesterday, I managed to pull off a full 24 hours on the stock battery. Today, I've only managed about 12. The difference? Today I had about a two hour session of Chip's Challenge on aLynx, haha. So, I'm pretty much draining half or more of my battery capacity just from a couple hours of Lynx emulation. Even if the battery I'm considering does have a capacity of 2300mah, I'm thinking I'd probably want over 3000mah if I keep up this kind of gaming habit. So, I guess I'm considering the 3500mah battery with extended cover from California, now.
I'll only miss having the back in a matching color a bit, but I really wish I could still use it with my dock. Do you guys think the phone would fit well on the dock with the battery installed if I removed the battery cover first?
EDIT: No, I don't think it would fit on the dock at all. I just tried with my stock battery cover off to see where the battery lines up, and it still comes below the lip on the dock. This is a really tough choice.

[q] gold 2430mah battery for samsung i9000 galaxy s

Has anyone come across this before? Any reviews? Is this the Slim one?

I have never heard of this, but it looks amazing! Thank you. I'm gonna ask the seller. Seeming that the description claims it to be a Lithium Polymer battery it is very likely that it is normal sized. In the past I searched around and never found a lithium polymer battery for the Galaxy phones. It would be really nice if all phones had high capacity lithium polymer batteries.
My question is that something for the 19000 battery wise is the same size as all other Galaxy 1 variants correct?

Yes, you are right. After some more research @Wikipedia, LiPoly Batteries can have high capacity and can be used safely provided that you use the original chargers and not the cheap Chinese crap. BLE is not needed for them . I might buy one soon, If i do, will update this thread. Wish me luck.

Well ebay says he's got positive feedback so just keeping my fingers crossed.

Hi !
Any feedback about this battery ?
Did you received it in time ?
Is it really better than the 1500 or 1800mAh ?
Thank you

To good to be true I think
I'd also love a battery which claims what this one does at this price, but It seems to good to be true. A bit of Googling shows a review for this battery with 2/2 "average" reviews which show it did not perform as promised (but it did work). There are also some other review sites which say pretty much the same thing. (I'd love to post the URL but can't because I'm a noob. A search for B005O8S4V0 on amazon.co.uk will find this.
Also, I think that if this technology was legit Samsung would have shipped it with the unit itself !!
Pity, I was really hoping it would work. I hate it that all the aftermarket batteries I have purchased sucked compared to the original.
DG

Yep i've finally bought a 1800mAh PolaCell battery. It seemed more secured to me.
Maybe i'm wrong (I hope for those who bought it) but as you said the 2430mha chinese one is too cheap to be true.

Lithium Ion is different to Lithium Polymer, the one on the link is a Lithium Polymer
More Details here
Code:
http://jartiuch.wordpress.com/2007/11/01/nimh-or-li-ion-or-li-polymer-what-to-consider%E2%80%A6/
Basically, Lithium Polymer batteries can have the same size but higher capacity, so there is a good chance that the battery is real.
But again I haven't still bought it cause I am running on a tight budget, but I am planning to buy one when I am selling my phone so that I can buy an Galaxy S3.

That doesn't look like it could be a Li-Ion Polymer cell due to the rounded edge. Only a square edge or foil pack would mean it's a true prismatic cell which is the casing for Li-Ion Poly cells.
The 3.7V vs 3.6V already shows that most of these are using a technology better than just standard Li-Ion, so it wouldn't really be much of an improvement.
Different manufacturer use different materials for anode, cathode, and electrolyte and these Chinese companies use the cheapest ones. So you're either getting what you pay for or getting ripped off depending on how you look at the false advertising.

I heard this battery(same label/producer on other handsets) is very bad.

I think I grabbed the wrong one:
http://www.ebay.com/itm/28086765575...X:IT&_trksid=p3984.m1497.l2649#ht_3124wt_1163
It does look the same, but 2450. Interestingly it is made in Japan, not China. Here's the weight, plus the OEMs that I have for comparison:
32.3g OEM Captivate 1500mAh
34.3g Japan "Gold" 2450mAh
36.65g OEM Epic 1800mAh
So I was expecting it to come out around 1650mAh, but it gave me 1910 the first time. I'll use it for a few weeks and run another test. Not really sure what to expect though.
Edit: This battery is crap. 2nd run at 200mAh it failed at 4 hours, about 850mAh drained. Now it's hovering just over 3.5v, right over where the phone would shut down. Trying to get the rest out so I can cycle it again, but I think it will be getting a funeral tomorrow.

Been running the "2430mAh battery" for about a week now with Battery Monitor Widget. Estimated rating is ~1300 mAh. Not great, but still gets me through the day with light-moderate usage.
For $10 it was worth a shot. At least the battery isn't COMPLETE garbage. :S

I already have an 1800mah anker and it is working fine for around $10....I am getting an oem epic battery tomorrow hopefully and I just ordered this

Don't buy from that seller, seller1on1 did not ship a real mugen battery instead he shipped a cheap ass 3500mah chinese battery and door you can get on ebay for $8.

This has been the strangest battery. After the second cycle I got 2300mAh out of it, but the phone was randomly shutting off. It started behaving after that though.
From what I understand some of these no name batteries come from good manufacturers' fail bins. They sell them off cheap instead of dumping them in landfill. So if that is the case, it's kind of a gamble.

They give 2 years warranty and the battery is made on japan. :victory:

I just got the gold battery from eBay. 2430MAH along with the battery charger for charging the battery externally. It was about $8.50 and comes within a week. Just search i9000 gold battery. I'm pretty sure I've got it calibrated. With light use I get up to 13 hours so far and up to 10 hours approximately with heavier use. Amazing buy so far

Galaxy Nexus After Market / Third Party Batteries with NFC

Has anyone found any on Ebay or else where that have maintained true NFC functionality?
I've seen a few on Ebay but the labeling is so "China town," I don't know if I trust them.

Did you try Amazon? I think Seidio makes some.

If you want extended look for Hyperion brand. Got it on eBay for $20 and the nfc works great. Battery life more than doubled too. Well worth it.

The most reliable battery makers are

Mugen
Both have 3800 - 4000mAH batteries available with NFC support. Will cost ~$90 though.

Seidio or Mugen don't use any better of a battery than most of the cheap ones. You are just paying for a name and false security.

Those battery are also made in China. You just pay more for their brand.
And those two brand don't even have their own factory.

Hyperion review
Just got this that arrived yesterday morning:
http://www.amazon.com/Hyperion-Exte...APABILITIES/dp/B007C8XRJY/ref=pd_rhf_gw_p_t_1
I guess I'm one of the lucky ones, after reading reviews, because the cover that came with my snapped right on, with no problem whatsoever. I started fitting it at the bottom and worked my way around snapping the clips in and wala - perfect fit.
I also bought this cover:
http://www.amazon.com/Hyperion-Exte...ompatible/dp/B0083HHU5A/ref=pd_rhf_gw_p_img_2
It's black/honeycombed and fits perfectly over the new back, giving the whole phone a factory made look. The only "negative" to it, is the volume buttons and the on/off buttons are now alot more sensitive - the cover goes over them and it doesn't take much now to depress one of the buttons - I'm actually liking it more, as I get used to it, but I imagine you could carve the rubber off at the buttons with a knife if it bothered anyone.
Anyway, after reading the little card that comes with it and the "charge it for 12 hours, kill it 4 or 5 times cycling" - I plugged it in and after about 2 hrs, it was saying fully charged. I needed to use my phone, so I turned it on - made a couple phone calls with it and decided just to use it. I read cycling doesn't matter with a Li battery anyway, and I was just excited to see if this thing was for real.
It's 10:43 the next morning - my battery has 19% left on it and it has been on the battery for 18hrs, 8mins when I unplugged it yesterday!!! I am a heavy user too - all throughout yesterday, played a few games, many visits to facebook, web surfing texting, 10 or so short phone calls - then again this morning, surfing the web for a good 1.5-2hrs gathering news.
All I can say, is this is unheard of - I've NEVER been able to do this on the stock battery. I'm going to run this all the way down today, so I'll post back when it actually shuts down, but it's for real folks - order it! I'm thinking about ordering another one for backup - I'll only have to charge once a week!

In this case, quality matters. I've already researched the differences. You won't be getting as good battery life as the one's from Seidio or Mugen. Please do the research before saying such things, as you're misleading others.
It's already been confirmed that the cheap Ebay batteries are of low quality.
Just because it's Made in China, doesn't reflect the quality of the build. Seriously? Everything is made in China...
Look through the posts on this forum about the ebay batteries. Almost everyone says they found barely a difference with extended battery.
Please check out this thread: People that bought the cheapo ebay batteries say the quality was terrible.

Poor results

In this case, quality matters. I've already researched the differences. You won't be getting as good battery life as the one's from Seidio or Mugen. Please do the research before saying such things, as you're misleading others.
It's already been confirmed that the cheap Ebay batteries are of low quality.
Just because it's Made in China, doesn't reflect the quality of the build. Seriously? Everything is made in China...
Look through the posts on this forum about the ebay batteries. Almost everyone says they found barely a difference with extended battery.
Please check out this thread: People that bought the cheapo ebay batteries say the quality was terrible.

If you read correctly I said most of the Chinese batteries. My statement still stands. You are paying for a name and false sense of security.

Your statement doesn't stand. You're insinuating that the cheap-o Ebay batteries are just as good as the Branded Seidio / Mugen batteries, when that is clearly not the case.
Shifting the goal posts aren't ya. Seriously, stop spreading misinformation. I gave you at least 3 sources from various forum members that concurred the battery life discrepancy is vastly different between the generic and branded ones. (Mugen/Seidio)
Did you provide a source showing that the generic ones off of eBay have as good or better quality than the branded ones? Looks like no.
I have sources to back my claim up, you have, well, none.
example of a bad battery (trexcell)

and FYI, Seidio uses battery cells made from Japan.

I have both the seidio and the hyperion NFC batteries and they both work well for me. Can't complain about either of them. 5 hours plus screen on time usually. Yeah yeah, mod this kernel and underclock/volt that kernal and "I can get that on stock"...well I can't. I like the bigger battery as well.

I'm going to run this all the way down today, so I'll post back when it actually shuts down, but it's for real folks - order it! I'm thinking about ordering another one for backup - I'll only have to charge once a week!

Went 24.5 hrs before it gave up and shut down - recharged to 100% in about 2 hrs and I'm at 14 hrs running with 66% left - I'm loving this! And as mentioned, I'm preferring the bigger battery/weight feel in my hand, then before. Maybe Samsung should make their phones with bigger batteries and heavier!..lol.

Wondering about this as well

So, is there any NFC-battery somewhere around 2-3k mAh? I'd love to get some more hours in between every recharge (i can barely get home from work before the phone wants to die), but the ~3,8k batteries just makes the phone too bulky for my taste..

Mugen has a 2000 mah one.. I've had it for 5 months and it works great. Definitely gives you the extra juice while it still fits with the standard battery door.

How much do the good Chinese batteries cost?
How does one identify the good ones in advance?

I have the Hyperion 3580mah battery and love it, NFC works, and I get about two days of battery life with a single charge

i bought 2 for the price of one plus came with a battery dock charger all for $20 delivered i thought i might aswell give it a go as cheap ass.But a day before receiving it i realised we had NFC in our battery which i didnt know and the batteries that i bought dont have NFC.

How about you start by telling us where you go these batteries? As for NFC, it stands for Near Field Communications. It can be used in a way to pay for items, or bumping phones together to share information, such as pictures, contacts, etc. I am not a fan of it, I always have it turned off in my phone settings.

yeah i wish to know as well, seen these tonight on ebay and i will buy them but just wanted to see if anyone else has first. was gonna get the £6.99 single one first as a test. It does say on the sticker under the battery 2100mah so just wondering if running a 3200mah would be detrimental? or is it one of those things manufacturers do and have very large tolerances just to be on the safe side so as not have flaming s3 videos on youtube.

don't these cheap batteries pose a risk of leaking in the phone or something? Like what if the damage the phone!?

What, where did you hear that? The only thing I have seen people have to worry about with cheap batteries is how much of a charge they hold and how well they actually work. I have seen batteries malfunction due to ****ty car chargers before though but never just a battery fail while in a phone minus ghost stories from trolls on the internet.

mAh has nothing to do with the amount of current or voltage so I don't know what you mean by manufacturers having large tolerances?? And it wouldn't be detrimental, it would add to your battery life. (as long as the mAh claims are accurate)

Bought this.
http://www.ebay.com/itm/170920078533?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

these are surely too good to be true? 3200mah in a standard size?

yeah no need for a new back cover

Can anybody say something about how long does the phone works with this battery?

definitely need to get me one of these.

too good to be true
hey i just made some fast research on the seller of the item
i cant link the url apparently because i jus made the account but go ahead and check the ebay sellers' (utigertech) feedback. They are not good.
in short, this battery is fake and some user feedback states that it does not last even longer than the stock 2100mah samsung oem battery
so dont be fooled. If its too good to be true then its probably too good to be true
cheers boys

Testing of MPJ 3200mah Battery for S3
I have purchased one of the MPJ 3200 mah batteries for the Galaxy S3. I have bench tested the battery over 7 days with multiple charges and discharges.
The results are that the battery is approximately 2000 mah it does not even come close to 3200 mah. The sellor is being misleading on the mah and you are better off buying a standard battery as it has 2100 mah and NFC.
I will try and test a few more batteries in the next couple of weeks..

Thanks for running the tests. Aftermarket battery sellers are notorious for jacking up the mAh rating.

I'm amazed that so many people get sucked in by these fake batteries. There is no battery technology out there that lets you increase the capacity without increasing the size.
