Hmmm you make a damn good point in comparison to the brand of batteries...I'd take Duracell over the same size flea market battery, so with that bieng said...I'm going to update this thread right now with some pictures I just took, and hold off on trying out the new 3500mAh battery that came out untill I've put this "good quality Yoobao" 2800 mAh battery through it's proper paces....just to be clear you ARE vouching for the quality of the Yoobao batteries right?
[Epic 4G Accessories] tony45x220:
Gonna take about a week to get results for consistant performance, I'm finna put it through the proper recalibration paces...check back in about that time frame.

And you can't just buy the cover...I think the maker of this 2800mAh battery mentions that to someone else who asked the same question about the cover a couple pages back...they are all sold as a battery and door pair.
[Epic 4G Accessories] playcs:
Based on other threads I've glanced over and the fact that it's generally more expensive than the generic, I think the Yaobao have better quality control over their batteries, hence you are more likely to get an acceptable one.

But as for me, I"ve decided to take a calculated gamble on the cheaper generic 18.99. I've read that many people have gotten good experience with them. If anything, I'll return or exchange it. It's more hassle, but I'm willing to deal with it.
[Epic 4G Accessories] tony45x220:
That sounds good Mr. playcs...and you know what this works out good because by the time you get your "generic" (as you labeled it) 3500mAh battery I will have had ample opportunity to test the supposed higher quality Yoobao 2800mAh battery and I'll make sure to post them in my thread and send you a personal message with the results.

I'm glad I got that bit of information as far as the quality of the brands...because I was seriously kicking myself a little bit as soon as you posted the link to the 3500mAh battery...but not so much now because of the credibility of the brand I have...even thought it's 700mAh smaller...we'll see how it goes...appreciate your contribution "playa"...hehe (put that just to piss off some of the other immature pple commenting earlier in this thread hehe)
[Epic 4G Accessories] KOYHOY:
Just wanted to say, "mAh" stands for milliamp-hours, not just milliamps. Not a big deal but in case you ever need to compare, the term means how many milliamps the battery can output in an hour before it "dies" so its misleading. Thanks for putting up the vid, I got a fairly good idea of the size of the pack and Idk if it's my style. Let us know how your batteries do in terms of discharge/quality.
[Epic 4G Accessories] ranchosteve:
Wow thanks for the head's up on the 18.99 ebay one. I like how the hump seem's to be only be were the battery sticks out.
[Epic 4G Accessories] tony45x220:
Oh yes I'm hip that it meant hours....just didn't know the clear cut definition of it, thank you for the explaination...no I won't be so hung up on the value of the number on the battery in mAh.

Thanks it was just to get a general view of the battery itself and I'll be posting another youtube video once I go through a few charge and discharge calibration cycles.
[Epic 4G Accessories] playcs:
I ordered the 3500 mah battery off ebay.

If you guys notice, the battery label says it's for the I9000. On top of that, shouldn't the 3500 mah be slightly bigger than the 2800 mah batter? If it turns out to be a 2800mah, it's still not bad for the price.

anybody seen a review for this type of battery anywhere?
[Epic 4G Accessories] tony45x220:
There are reviews all over youtube for every droid out inc. droid x, droid 2, incredible...etc, most all of the HTC phones inc. EVO, Nexus 1, G1, G2, HD2 etc, and most of the black berry and palm pre phones. I see people getting up to 3 and 4 days with light usage...and 2.5 days with regular usage...but with heavy usage any battery with 3500mAh should last at least 2 days with any usage over a stock battery <1500mAh
[Epic 4G Accessories] egzthunder1:
Alright, I just cleaned out 22 posts full of pointless bickering, fighting, name calling, and tons of foul language. None of these are compliant under Rule 2. Stop this, get back on topic or my next visit to this thread will not be as pleasant.
[Epic 4G Accessories] tony45x220:
Thank you Mr. egzthunder1...I couldn't agree with you more!
[Epic 4G Accessories] sniperwitagun:
can't wait to purchase one of these. should come in handy on long car rides but i doubt it will fit in my car mount. can you post the new dimensions with the battery in the main post?
[Epic 4G Accessories] tony45x220:
Didn't think of that...did you see the pictures and the youtube video I have a link to?

If you still want the dimentions I have no prollem posting them.
[Epic 4G Accessories] FokisMoney:
Thanks for all you work man, i commented on the youtube video but wanted to send props on here as well. You sold me, i'm picking up my epic (finally) tomorrow and will be sending for the battery right after since the palm pre i'm coming from has always had battery life issues and i dont want to deal with that anymore. Again thanks for the thread
[Epic 4G Accessories] tony45x220:
Oh yea sho-nuff my dude appreciate it...im givin this particular battery so much love cause the name (Yoobao) is known for quality and the consistent results I've gotten...you won't be mad at cha purchase.
[Epic 4G Accessories] mapcom1:
Umm how are you guys carrying this thang? a new holster?

does anyone know whats the largest battery that will fit in its current size?
[Epic 4G Accessories] tony45x220:
Nahh I don't think there are any cases out for it yet...you might wanna check the Siedio sight...they finally have the picture up for their extended battery and they always make cases for their phones, but the biggest battery out for the epic now is 3500mAh...of the Generic veriety...I'm on the 2800mAh Yoobao.
[Epic 4G Accessories] Pvt WhoOkid:
Do you have a link to this siedio you speak of? I'm too lazy to google.

Thanks.

- Its just going to be Epic!
[Epic 4G Accessories] Vertig0:
I think what he's trying to figure out is which is the biggest battery that will fit in the phone using the original back cover.
[Epic 4G Accessories] tony45x220:
OHHH ight..yea Siedio has that FIFTY DOLLAR 1600mAh battery that will still fit under the stock cover...can't imagine anyone spending $50 for an extra 100mAh when you can spend under $20 for an extra 2000mAh...but if style is your #1 priority then hey...

but yea the 1600mAh siedio will fit the stock cover
[Epic 4G Accessories] tony45x220:
Oh wow...that's the lazy statement of the day...lol, jk but here you go mane:

Yoo can I ask how you make the timeline of your phones and all that other information automatically appear under all your posts?
[Epic 4G Accessories] m5james:
How are people testing their battery life though? Things can vary widely between users, from what people consider normal usage, screen brightness settings, SetCPU, time on WiFi vs 3G/4G, apps installed and running, etc...I remember on the Moment forums w/ people mentioning using Noobnl ROM's and getting a full day of use, but I'd never get past 3-4hrs. A consistant way of testing is required instead of just spitting out random numbers for bragging rights.

I'm going to be doing my tests again...fully charged overnight, running Pandora, Slacker, TuneWiki, Skype and running a movie all at the same time to drain the battery as quickly as possible, then recharging and doing each step over again, timing it all. I was able to get roughly 3-3.5hrs of both usage and charging times w/ my current ROM and stock battery, so we'll see what the 3000mah battery does. I'm not expecting 2x the life since it doesn't work like that, but I do hope to get another 1.5-2hrs out of it.

EDIT - I stand corrected on my own guesses in regards to battery life, I got almost double the life after all! Here is what I have so far, a few more testing cycles to go:

STOCK 1500MAH BATTERY

Phone off from 1:19pm - 4:29pm = 3hrs 10min to charge

Phone on from 4:32pm - 7:07pm = 2hrs 35min to die

Phone off from 7:10pm - 10:15pm = 3hrs 5min to charge

AFTERMARKET 3000MAH BATTERY

Phone on from 12:05pm - 5:04pm = 4hrs 59min to die

Phone off from 5:18pm -
[Epic 4G Accessories] idontwanttostudy:
5 hours still isnt much time though considering you have to pay and lose some cosmetics which in my opinion isnt a big deal. What I am not sure about is the buldge, I am a constant texter, is there a substantial difference in the feel and comfortability when texting?

Also, have you tried it with games and emulators? I use the psx4droid quite often and am curious to know how it holds up under that condition.

In the end I will probably just keep a charger at home, one in my backpack, and my car charger so no matter where im at i can charge it lol
[Epic 4G Accessories] m5james:
I'd consider almost 2x the battery life during my testing cycle pretty good, especially since this cost me $ shipped. Looking on eBay now, they're around $12 shipped for buy it now ads. I'm a huge texter as well, and it doesn't give me any issues.

It's a little harder to play games for 5hrs to see if it lasts the same time vs testing it via letting it sit there on my desk while I'm working, so I couldn't really tell you how it last gaming as of yet. I know about 2 weeks ago I was on the stock battery, using GPS and playing some Gameloft games and playing around w/ Google Earth and only got a little over an hour...but it was also having ROMbKernel issues that I noted in my signature.

I always keep a charger near by...in every car and even wired in a cigarette lighter port onto the bike. I found car chargers for around $1.50 ea shipped. They're not Epic specific, but they use MicroUSB plugs and work great. Ever since my Moment, keeping a charger near by is the nature of the beast w/ these phones, but getting this battery should help for when I'm not around one.
[Epic 4G Accessories] tony45x220:
Are you serious it took you 5 hours to kill a 300mAh battery!?....was it charged to 100% or was that out of the box...after my first charge of the 2800mAh Yoobao...It took me 13 hours of serious abuse even leaving the LED flash running for a few hours to finally make it die. And as far as people coming up with different results...I got this 60+ hours using the phone on a day to day basis...and you'll see my usage details in my youtube video...people don't live their lives the same so a consistant way of testing probably wouldn't be realistic...some people are business associates and others are sports junkies watching highlights all day, others are on AIM and Facebook all day...but 60 hours with plenty of calling and 300+ text messages is basic real life usage...so I'd say 50 hours give or take a few could be stamped on this Yoobao 2800mAh battery.
[Epic 4G Accessories] m5james:
No, I said it was a 3000mah battery, not a 300mah. The 5hrs was streaming, various apps running and watching a video.

Did you even read my post? I said the same thing...that people run all kinds of different apps, roms, etc, which is why I'm doing my testing by doing something consistant vs variable amounts of texts, phone calls, etc like you are trying. My method would be more consistant that your because mine is easily repeatable time and time again. What about the LED flashing? You do realize how little energy that red light uses, so I don't see why you're even bringin that up. Now if it was halogen, then you could use that as an example. Streaming constantly for hours on end kills a battery far faster than making calls and/or texting...I learned this years ago since I've been streaming music and draining batteries in no time flat using my Treo 755p. Now that I only use my Treo for texting and calls, I could probably get 3 days out of the 130mah battery it uses.

Your arbitrary hours number, by your own admission, is my no means consistant of how it will work for someone else based on th fact, once again that you admitted, that not one person uses ther phone the exact same way another person will. Just as I said in my own posts, there were people on Moment forums getting the 2 days of life while others (myself included) got no where near that, so maybe you're not the "power user" you're claiming to be if you're getting 2.5 days of use.

All I know is, at the end of the day, I spent $6 and doubled my battery life based on concrete and repeatable testing, not random uses via texts, calls and whatever you may have done.
[Epic 4G Accessories] tony45x220:
Your right...but I know I mentioned the fact that people do use their phones differently (the example when I mentioned business people, to sports fans, to social networking addicts) I think this is the part we can agree on...and my B I meant the camera flash...I left the light on the back of the phone (which I think is an LED flash not "notification LED") for the last 3 or 4 hours to kill the battery because I don't have anything to stream with or qik with...but yea I know what chu mean, that's why I also included an adjusted average usage of 2 days among different people...and I'm confident results will be at least half of what I got around 30-40 hours unless your really going extra hard constantly and intentionally trying to drain the battery...I left this phone in airplane mode overnight and while sleeping for 9 hours and DIDN'T LOOSE 1% OF CHARGE...and I BS you not. I'm making these claims and my opinions not based on peoples different setups and settings and usage patterns but based on the quality of this battery and how well it holds the charge which is a constant anybody can agree on.
[Epic 4G Accessories] thomasskull666:
I love to see that you are or were running Emotionless Beast in those screenshots lol. And my old battery mod too lol
[Epic 4G Accessories] tony45x220:
Oh yes I like the regular Baked Snack theme but the Final Emotionless Beast has a lil more swagg to it lol, battery mod is very handy as well.
[Epic 4G Accessories] Pvt WhoOkid:
After reading so much cons and pros about so many batteries I just dont know which to go for. This one that you've got or this other one http://www.seidioonline.com/product-p/bacy30ssepc-bk.htm I'm at a freaking lost now haha.
[Epic 4G Accessories] muyoso:
70 dollars? Get the 3500 mah one off ebay. It will have the same amount of real world battery life as the 3000 mah Seido, and it saves you 50 dollars.
[Epic 4G Accessories] Pvt WhoOkid:
Everyone keeps sayin its "generic" i just don't know anymore lol
[Epic 4G Accessories] heathmcabee:
Damn, I kinda wish I wouldn't have a bought 4 xtra 1500 batteries just after release. If it weren't for that, I would grab one of these up, but I dont think it would fit in my leather case correctly with the extended battery. I can go all through work with 2.2 release now and about 20% left (8 hour day somtimes 9) and be just fine before switching and using one of my backups. If I really use my phone, I pop another one in and always have them in rotation. When these get rather cost reasonable, I think i would much rather switch to maybe 2 or 3 of these extended batteries for less of a hassle of on my time with having to charge the batteries in my dock.
[Epic 4G Accessories] tony45x220:
Yea $70 is ridiculous...especially for only a 300mAh battery, and there even charging $50 for the 1600mAh...really...smh, trust me this 2800mAh is giving me CONSISTANTLY 2 days between charges...its a quality brand and its reliable...airplane mode ovrnight I loose no more than 2% charge...have u seen my youtube video?
[Epic 4G Accessories] tony45x220:
Its generic because its no name brand unlike the Yoobao brand of my 2800mAh bateptery that seems to have a general credibility even among other extended batteries...that 3000mAh battery is just like a big ass flea-market battery...ironic thing is that its $30 more than the name brand...u got the review and the credibiliy...save yaself a few $'s and give the Yoobao a shot
[Epic 4G Accessories] tony45x220:
That sounds like a LOT of fun having to be on top of your phone like that every day...quick thought, while conditioning this 2800mAh it took me 13 hours of rude abuse to finally kill it from the 1st full charge...the charge just doesn't move when your not using it (with all data off sync, gps, bluetooth, etc.)...id say at least 24 hours of real world heavy usage with this battery...at the minimum.
[Epic 4G Accessories] durhamite:
I received the 2800mah battery last night. Lets see if I can get 60 hours out of it. The ebay transaction went well (which I am always skeptical of since I have been burned in the past) Will report back later my findings. Thanks for the post OP!
[Epic 4G Accessories] Pvt WhoOkid:
I might just listen to you and get this one. I just need something that can hold a charge for awhile. I'm a heavy user and I'm always on my phone, I get tired of keeping my phone plugged in the charger all the time while at work.

I have 2 "generic" batteries I bought from ebay, you know the $9.99 ones that come with the charger dock 1500 mAhs and I can say they work just like the stock ones, which sucks! But hey as long as it lasted as long as the stock I didn't care.

Now I'm at the point where I get tired of switching between batteries so, I might just dive into this one.

- Its just going to be Epic!
[Epic 4G Accessories] konaman:
Hey tony, thanks for this EXCELLENT review! I'm gonna order one of these now!
[Epic 4G Accessories] playcs:
I just received my 18.99 3500mah battery yesterday. I'll post some results later.
[Epic 4G Accessories] tony45x220:
Lol no doubt it will be and epic jump in convenience for ya busy work day, and like I told the other guy switchin batteries constantly...u can abuse this battery all u want...from a full 100% charge id put a MINIMUM 24 hours betwn charges (it does need to be conditioned just like any other battery thoe)...I consistantly get 48 give or take on medium-ish usage to put it realistically for the masses
[Epic 4G Accessories] tony45x220:
Not a prollem Mr. konaman! I tried to cover errything the average hacker would inquire bout, post up some #'s up here once its broken in
[Epic 4G Accessories] tony45x220:
Ohh yea do that id like to get a good comparison going btwn the 2 main batteries pple are talkin bout.
[Epic 4G Accessories] m5james:
I know I've got plenty setting changed and little apps running in the background that contribute to my battery death...video live wallpapers, full screen brightness, countless texts, email servers, etc. The camera flash is still an LED, and as bright as it is, it's still not a power consumer as the equivelant halogen bulb would be...plus I would never leave it on that long as I've heard of people having issues w/ burning diode from being on too long, like as a flashlight. Airplane mode is the same thing as having the phone off if it's just sitting there doing nothing. Now if you were in airplane mode playing games, that'd be a different story. Just lastnight my phone was on the charger until I went to bed at 3, but I figured instead of plugging it in, I'd leave it off for the the hell of it. Even w/ emails still coming in, watching a quick 30 min video and w/ whatever little apps that stay running even when the screen is off, I was at 98% percent this morning at 9.

Now I just wish I had a Sedio style battery cover vs the one I got I don't like how it slides in and out of a jean pocket, even w/ the nice angled edge it has.
[Epic 4G Accessories] Pvt WhoOkid:
Post pic and video of your extended battery.

- Its just going to be Epic!
[Epic 4G Accessories] m5james:
Nothing to see, it's just a battery and cover like Tony's...difference is mine is 3000mah and I got it for $6 shipped. Nowadays they've just up to $12, which is still a good deal considering what it does for the life of this phone.
[Epic 4G Accessories] m5james:
Custom ROM'ed or not, you still need to cycle the battery through a few complete charges and discharges...I did mine 3x before posting a result. I've still yet to update my post, but you guys get the jist of it...I've doubled my battery life, if not more, depending on usage.
[Epic 4G Accessories] playcs:
hm, i'm not convinced cycling works with lithium based batteries like they do on nickel cadmium based ones. But I do plan to calibrate it correctly.

according to seidio's version of the epic 4g extended battery, it suggest you leave it charged when it hits 100%. I find that the phone stops charging when the blue light goes on, but a way around it is to leave it plugged in and in use, e.g. talking on the phone or tethering.
[Epic 4G Accessories] ultra78721:
Thanks for the review tony...I ordered me one last night:rolleyes: Since the guy is from texas like I am..I assume he shipped today and should receive it by thursday max;)

If i take it off the charger at 9am and make it through the day from reg to med usage. And make it home till 9 pm With out charging it ,I would be happy with that;)
[Epic 4G Accessories] tony45x220:
And you said this was after you did the 3 calibration runs right?

I agree with it not burning as much juice as a halogen bulb...but for the purpose of what I was trying to do...we're all Samsung Epic 4G users and there is only one kind of camera flash which did help to kill my battery...as far as the burning diode from bieng on for too long...I didn't know that...(I'll make sure to find a different way to kill my battery...I think I'll leave the LED camera flash method alone...lol), I will admit that when I went to sleep I killed everything unnecessary with a handy dandy app called "fast reboot" and then put it in airplane mode sleeping from 12am to 7am for both nights when I got the 60+ hours....but other than that I wasn't shy texting all day and making all my necessary calls as you saw in the review...waiting for those updated #'s
[Epic 4G Accessories] tony45x220:
Oh yea no doubt the shipping was a lot more convenient than I expected especially me bieng in upstate NY recieving a package from Texas...but yea if you take it off the charger at 9am...(you do need to calibrate or "break in"nthis battery just like any other new battery) TRUST you won't even think of touching the charger till I'd confidently say AT THE VERY LEAST a day and a half ( in your case 9am to 9pm the day after) and that's only if your constantly goin in all day on your phone...but this battery gives me a steady average of 48 give or take a couple hours per charge, and this is with regular calling and messaging, checking E-mails and facebook...very good look this Yoobao battery is.
[Epic 4G Accessories] ultra78721:
I got this battery because in my opinion its like choosing a rayovac battery vs a duracell/energizer.

Rayovac will have the ((same power)) but will not last as long.

In this case wont last as long and wont have as many charges before it dies,

In my experiences those cheapo battery's will stop holding charge after a while and some of them,u will get less power after so many charges:(..you do get what you pay for;) I have avoided this by getting seido battery's but i'm gonna give this a try:D
[Epic 4G Accessories] Pvt WhoOkid:
And its at that point that I will get the seido, till then this one will do. I don't know but 70 bucks for a battery? Geez it better last me 4 days without charge at heavy usage. I'm on my phone normally for 8hrs straight at a time.

- Its just going to be Epic!
[Epic 4G Accessories] durhamite:
After one day with the 2800mah battery here is what I am seeing

from 100% to 22% in 23h 23m 55s with medium use. I am running the nebula dk28 rom. If I get this type of results consistently I will be happy
[Epic 4G Accessories] playcs:
I'm currently using the 3500MAH battery bought from ebay for 18.99.

I can verify that I'm getting at least double from the original oem battery. your experience will vary from mines. Just think of what you're getting right now and multiply that by 2. Don't expect the battery life to last for several days over without a charge., that's just not realistic.

Those 12 dollar extended batteries as well as this 18 dollar one should be more than enough for your daily use.

there's one bad thing about my 3500mah battery. the battery cover is so snug it causes the down audio button to get stuck when you press it.
