I told a friend of mine in china to get me 2 batteries direct from Yoobao. I recycled the battery for a few days before give the battery a good and fair test, last Saturday I went to NYC and the battery lasted 12 hours. 3-5 phone calls 3 hours of navigation and I took and uploaded around 10-15 pics to Facebook. I'm still debating if it's worth it the extra super duper bulkiness..
[Epic 4G Accessories] tony45x220:
Are you talking about the 2800mAh or a smaller one....obviously a stupid question but 12 hours is crazy for this battery you must've really had to be going ham in with what you were doing...I've gotten 18 hours after turning on backround data, GPS, wireless location, and Wi-Fi...FROM 70%...are you running DK28 Froyo?
[Epic 4G Accessories] eddieyee:
I ended up buying the one for $12.98 on ebay (auction ID 130465404050). Received it today (wow fast shipping... I'm in Dallas and it shipped from outside of Austin). I also ordered the $18 shipped 3500 mah from ebay (auction ID 120654668364) about a week and a half ago... They both arrived at the same time (strange lol).

First thing I need to say: THE BATTERY DOORS ARE THE EXACT SAME. The 3500mah and the 2800 moretalktime sells are identical. Injection molding even has the same number printed on the inside.

That being said, BOTH had an issue... The area by the power button has a gap and doesn't snap close fully. See photos below.

Not sure how good both batteries are yet in terms of life. But see photos below of new battery door.

One thing I should mention that I really like--- The battery door acts like a kick-stand. Angles the phone back about 5-10 degrees if you lay it on the side.

Other than the battery door gap, build quality seems pretty good on both.

[Epic 4G Accessories] muyoso:
Yea, they are both probably the exact same battery, so buy whatever is cheapest.
[Epic 4G Accessories] J31Rob:
My partial review:​

First glance: comes packaged well, battery brand new out of plastic, case well protected.

Instructions were if the battery had a charge upon arrival, kill it to 0%, recharge for 12 hours.. repeat 3x. Came with a 73% charge, took ~22 hours to kill w/brightness on high.. don't have a screenshot nor do I remember many variables, sorry. I was power using for many hours though.

After first 12 hour charge using dock charger, I'm getting these results:

Not bad.. nearly 3x the normal time it takes to kill stock 1500mah. Very impressed, that alone is worth $40 to me.

[EDIT (11:26PM, 12/24/10)]:

End of the line for the first round:

SPACE RESERVED FOR FUTURE RESULTS

The feel of the cover is nice. Nice quality, just like stock. One corner gives me trouble though, never stays in place.. not a huge deal breaker but annoying none the less. It's even more comfortable at times than stock cover as it gives you a bit more shape to grasp while surfing or holding the phone in landscape in general.

Here are some peeeekchurs (click the thumbnails).

The pesky corner:

Attempt at a size comparison:

Trying to show how much more the battery pokes out than stock:

[/nsfw]

edit: pictures were huge, will resize in a bit. G2G for now

I'll update this w/more screenshots & variables when possible. I'll keep track of it but no telling when I'll have time to post due to the holidays. :rolleyes:

I cant click on the thumbnails.
[Epic 4G Accessories] tony45x220:
There not the same battery because I did the research. The 2800mAh Yoobao is an official japanise brand of battery...I updated this thread with the link to the website so you can check it out...I'm not sure who makes the Generic version of the 3500mAh battery that everybody says is the same size as the 2800mAh...that should tell you something right there.
[Epic 4G Accessories] J31Rob:
Fixing this now. I thought they were clickable but they're just small. :mad:

edit: Pictures are just gonna have to be huge. This is the only forum I've ever seen that has no autoresize.
[Epic 4G Accessories] myselfalex:
So much discussion to read in this, but all good info so far, thanks.

On a non-battery direct note, could someone post a picture of this "door" that the extended case comes with in action?
[Epic 4G Accessories] maxamis:
So does anybody that bought this battery know of a car mount that works well with it ? I'm super happy with the battery but now want to find a car mount that pick up that works with this...
[Epic 4G Accessories] Pvt WhoOkid:
When you find one, post a thread about it. Lol
[Epic 4G Accessories] zulubushi:
Though I appreciate your efforts to introduce the scientific method to this battery testing, I've been reading thru this thread and the air of snobbery emanating from your posts is palpable. This is the interwebz... get over yourself. And just like there's no "trailer trashbonics" there is no such thing as "ebonics." The notion of such a thing only supports the fact that this country hasn't come as far as we'd like to think.

/rant

Thanks for all the info you've posted Tony. I'm def a power user and use my Epic to the fullest so I'll be picking one of these up for when I go to conventions and other events which require long days and long stints away from a charger.

@Kevin You mentioned that you have to charge in the phone. Being new to Android, is that bcuz of how the OS calibrates system use/life with each charge/discharge cycle? I'm wondering bcuz I can't keep my phone of for 10 hours and I have the Samsung stand alone charger so I was going to discarge the battery, then charge in the stand alone which I know should properly condition the battery itself, but will that decrease efficiency during real use in the phone once I've completed the three cycles?
[Epic 4G Accessories] johnsongrantr:
you should try the CM6 beta, I have a seidio 3000mah battery my "time till last plugged in" is 2 days 6 hours ago and my actual battery percentage is currently 67%

note I have

went though several complete normal charge cycles

gps disabled

no data roaming

no wifi

no bluetooth

rendering effect set to "nexus 1 low red"

screen timeout set to 1 min

automatic brightness

i don't have any crazy apps installed like juice defender and I don't turn off my radio at night. I have facebook and twitter refreshing every hour. I've played emulators and angry birds for a couple hours also. This isn't all the battery's doing, I think most of it's mainly cm6, highly recommended you check your battery out with that rom.

I was previously getting about 24 hours on the 3000mah battery with normal stock based roms
[Epic 4G Accessories] eddieyee:
Tony45x220-- Can you fix your first thread... Yoobao is Chinese. Battery has a big thing printed on it> Made in China.

Just so people don't get the wrong idea.

Thanks :)
[Epic 4G Accessories] watermoore:
Just ordered mine tonight. I am excited about being able to use my phone as much as I want all day long. Thanks for making the video and sharing your find with us. I know I appreciate this kind of thing.
[Epic 4G Accessories] churro7:
cant find this on ebay link?
[Epic 4G Accessories] tony45x220:
Small detail I didn't even think about...thanks for pointing that out for me I'll update it now mane :-)
[Epic 4G Accessories] tony45x220:
you should be able to find it it's the 33 dollar battery that comes up with the rest if you just search "Samsung Epic 4G Extended Battery"....but if anything I have links on a couple of my Youtube videos...the links to those are at the start of this thread.
[Epic 4G Accessories] tony45x220:
Not a problem watermoore...glad I could be some kind of help :-)
[Epic 4G Accessories] tony45x220:
What exactly is cm6 BETA...is that a ROM or something to do with the filesystem like this whole EXT4 thing people are suddenly drooling over...personally I don't see the big deal...I get some of the same quadrant, linpack, and RL Benchmarks people are getting with the VIPERspeed fix on VIPERrom 4.

But I got the 85 hours on the VIPERrom 3....and I usually stick with what I'm comfortable with...and especially because of the speed I'm getting along with great battery life.
[Epic 4G Accessories] tony45x220:
Lol...I don't wanna start no ish on this thread but it got real ugly btwn me and mr James in the early stages of this thread to the point where one of the mediators had to come in and wipe about 20+ posts of ish talking out and give a warning...lol, but anyway not a problem...I'm a very meticulous person...if an average user like myself can get 3+ days out of this battery then even an abuser like yourself running business on your phone all day will go at least 24 hours doing whatever you want to do with the phone how you want to do it....hope it works out good for you like it did for myself...if there is anythang I can add here or to the information I covered on youtube let me know mane.
[Epic 4G Accessories] boominz28:
im pretty picky when it comes to batterys I want the one that wil last the longest on a stock rom no mods or anything. so to be clear from what i am seeing the truly 3500 mah is not actually a 3500 its a 2800 disguised?
[Epic 4G Accessories] muyoso:
I can't say for sure what the 3500mah battery is. Until someone tests both under exactly the same circumstances, there is no valid way to compare them. I was just doing a test with my 3500 mah battery when i dropped my phone and it broke, and I was able to go 22 hours with 82% left.
[Epic 4G Accessories] tony45x220:
I'd agree...I'll admit I havn't seen the 3500mAh battery up close but everyone says they are the exact same size...which to me is self explainatory...they have the same exact amount of cells inside...the 2800mAh is just telling the truth about it by saying 2800 instead of 3500
[Epic 4G Accessories] TWO515TY:
This may or may not be true actually, the size doesn't always indicate the maximum number of cells a battery can hold. Back in the good ole Treo days, the stock battery was 1800 mAh (if only our Epics came with 1800 mAh batteries). Seidio used to make an extended battery that was the same size as the stock battery, but was 2400 mAh - they fit an extra 600 mAh in the same size battery.

Theoretically the same thing could be happening with the 3500 vs 2800, although there's really no way to be sure unless someone does a very scientific, methodical test (i.e. exact same usage between two devices running the same battery) comparing the two. Not likely to happen here on XDA lol.
[Epic 4G Accessories] Pvt WhoOkid:
My problem is the replacement back cover. I really like the one that seidio comes with this one seems eh crappy to me. I haven't purchased any because I want to make sure I get the back cover I want with it. If only they sold the back covers alone. Id buy this battery and the seidio back cover :-(.
[Epic 4G Accessories] IcOpRo:

[Epic 4G Accessories] tony45x220:
I've gotta say that's not exactly impressive compared to what other poeple have gotten on this 2800mah battery, what are the hours you used to get on the stock battery if I may ask lol?
[Epic 4G Accessories] IcOpRo:
Ok thanks I might give that ROM a try then d u also have a screen off profile set?

Thanks for ur quick replay btw
[Epic 4G Accessories] tony45x220:
You make a good point...with that being said id take the credibility of a battery claiming 2800mah....if its the same size as another battery of the same dimensions claiming 700mah more @ 3500mah...

Regardless of the logistics from the results I've heard the 2800mah Yoobao outperforms the 3500mah in consistancy and overall performance.

But isn't there talk about the late 003 hardware having bad blocks and difficulty in loading custom roms besides sprint lovers and stock? My gf just got an 004 hw white EVO and I'm guessing that people have had more success with the 004 hw? I've just been reading into these hboot 2.02 s-off developments before I start rooting hers. I have an 002 nova from the early days that was rooted using toast's methods so haven't had the need to stay updated on 003 and 004 root methods until recently. Studying up on the current guides before I get a chance to sit down and work on her phone, probably this weekend when I have more time to dedicate. Good luck to OP.

eugene's a11/a12 kernel {link located further down in posting}

1. Odin with eugene's 2.2 froyo package

2. Boot back into recovery

3. Flash axura 2.0.1 rom (reboot)

4. Boot into recovery

5. Flash eugene's a12 "or" a11 kernel(reboot)

6.boot into recovery

7. set up lag fix, tweaks,etc to your desired settings..

8. reboot, it will go to a menu, i suggest using the first option to backup and restore!!

11.DONE!! Enjoy....

***UPDATE***

Ok, so i paired Axura 2.0.3 with #805 kernel and it runs flawlessly!!!

same method as before just a different kernal.. so for future reference when Axura 2.0.3 becomes available to everyone look back for this post{BOOKMARK ME!!]

UPDATE!!!

Axura 2.0.1 rom is the less glitchy..{just released 2.0.4 "early" with the fixes applied, flashing now}

the best kernel available as of now is Eugene's a12/a11 oc/uv!!! has all available lag fixes, tweaks, and misc stuff built into the recovery, and the voltage app allows adjustment in individual speeds!!

100mhz

200mhz

400mhz

It would be awesome to get Eugene's latest kernel (#106) working on Axura. Eugene stated that it should work on other roms as long as you include the zImage (duh) and the /system/init.rc. Tried doing it with a flashable zip as well as flashing just the kernel and then using adb to push the init.rc but still couldn't get it to boot. Maybe a much more talented individual could get this set up working.
[Vibrant Android Development] jcc332006:
Is it possible to flash axura 2.03 and flash the kernel by using CW? I believe kernels can be induvidually flashed right without odin correct? Thanks.
[Vibrant Android Development] joe.kerwin:
So I'm already on Axura, so I can just jump right to the flashing of eugenes kernel through cw recovery, correct? Don't get why I'd have to odin eugenes froyo package. I hate odin if you haven't guessed by now lol.

Also, which one is supposed to be better? 802 vs. 805
[Vibrant Android Development] jcc332006:
Yeh I hate odin also. I believe we should be able to flash in cw. I dont see why one would have to flash eugenes rom also. Im curious. Anyone care to expound. Thanks!
[Vibrant Android Development] htcfresh:
Correct...if your already on Axura your fine, except if you have any voodoo lag fix our oclf lag fix..you would have to remove them first...I personally like #802..but to each his own
[Vibrant Android Development] htcfresh:
Yes as long as it is a flashable .zip

Kernel and not made for odin..but thus far out of all the kernels eugene's #80x kernels are the only ones that work and are cwm flashable..

After I install the ext2 files, it says I already have a lagfix installed. I followed your procedure correctly but with Axura 2.0.3 and kernel #802.

did you restore boot image!?! if so i dont have an answer, other then odin and reinstall axura rom and this time use the newest working kernel, build a5 #120..links in the first post now..

Im getting reboot issues with the a5#120 kernel anyone else?
[Vibrant Android Development] htcfresh:
What kind of reboot issues? Were you running a rom other then axura when you flashed 2.0.3? Best bet is to odin and do it all fresh and only flash one at so time with reboots between flashes...and disable any lag fixes!!
