[Battery] Epic Touch 4G Battery With The Fascinate

So after reading about vibrant users having success with using the epic touch 4g battery. I figured I'd order one up. Why? Well both of my batteries are a year old and I can tell they have degraded over time. And this one is 300mAh MOAR!!!! than the stock 1500mAh battery that came with this device.
http://www.mobilecityonline.com/wireless/store/productdetail.asp?productid=28506
The new battery is just about 1/64th of an inch thicker than the fascinate stock battery but it still works with the stock battery cover. Just into the first full charge and I can tell a difference already with screen on time at an hour with 84% left. Where normally after an hour of screen from a full charge I would be at 70%. The one thing I notice though is the battery does not charge in my spare charger that I got from vzw a year ago. It must have the same hardware check that the phone does. But since I'm running an mtd rom it charges fine in the device since the hardware check is not included within mtd kernel source.
***TOUCH WIZ USERS*** The fascinate has a hardware check that will only allow for the use of "vzw" specific batteries. So before you order one confirm that your current custom kernel has the hardware check disabled and that you can use/charge 3rd party batteries.
good day.

how do you check for the hardware disable. im running on the GeeWiz 2.0 Alpha EI20

Ask whoever compiled your kernel.

I've been using the Epic 1500 mah batteries for a long time now. I was getting them off eBay for $2 a piece including shipping brand new out of China. Just ordered 2 more this morning, although they've gone up to ~$4 each with shipping. I use two external aftermarket chargers as well, so I rarely ever charge them in the phone. That's why I've never understood the battery life worry, I just carry a spare battery. (Have 7 now, but we have two fascinates in the house)

errr right.... But the battery in the the op is from the sgsII line and not the original sgs variants. The fact that the epic sgsII came stock with 1800mAh is what I was interested in.
good day.

Yeah I realize that, my point was even though that battery is cheaper than the OEM battery for our phone, the battery I mentioned is still a fraction of each. At $3.70 a battery I can have a lot of 1500 mah batteries to one 1800 mah batteries. Although I may have to check eBay and see if I can find the new 1800 ones dirt cheap too.

Nice info chopper

Thanks for the great info. Just ordered one for my Fascinate running MIUI/Glitch. The additional 20% in battery capacity will definitely be welcome.

I too just ordered one, I need the extra battery, I eat it up at work and then dont have enuf left for the night time. I love my phone and I always seem to need to do something on it.

Very pleased so far. I wanted to give a couple charge cycles and time to settle in. But it almost feels like them good ole DJ05 days of yesteryear in the battery department with this thing. I had ALOT of downtime today at work and hammered the device (found a sweet disc golf game and logged about 1 1/2 just on that ) today and just watched the battery level trickle down. And even did some maps with gps today (who knew there are like 4 sheridan rd's on the north side of chicago that run e/w and n/s) cause we got lost.
Background of my current set up:
Pool Party 1.4.1 (mtd rom) which includes jt0912 kernel within rom.
I sync gmail and have fancy widgets update every hour. Twitter is done via a colorize widget that I have set to manually update when I feel like it. The rest of the screen time is reading emails and xda and rootz apps with some surfing in between gaming. My screen brightness setting is always at 45%. Oh yeah forgot, 25 minutes of talk as well.

would have been nice if this battery came stock a year ago.
good day.

Ohhh the dj05 days.. I miss those much. Used to listen to music all day at work, 8 hours of media server running and some web surfing and would get home and still have 80% battery left.. Wish someone knew why that service release sipped the juices so slowly..

I got the new Epic Touch 4G battery yesterday. I charged it to 100% with the phone off, rebooted into recovery and cleared Batt Stats. Today I'm going to let the phone run down to almost nothing before charging again. Any other suggestions for maximizing battery life?
Also, Chopper I noticed your Cell Standby is much lower than mine, I'm at 24% and my Display is at 14% with only 1h 25m time on. Any suggestions on improving/reducing Cell Standby battery usage?
I'm running MIUI 1.9.16, the last Glitch kernel, and the EC09 radio.
Thanks.

Move to a better signal area, haha.
You could try updating your PRL (*228 option 2).
Just ordered mine, should get to me late next week. I chose Economy shipping cause I am poor as all-get-out.
Also, Google Checkout is probably one of the best things evar. Don't need to register with ANOTHER site? Okay, thanks Google.

Well, shoot. Was gonna post a big hullabaloo about finding this battery in the Vibrant forums, and I've been beaten to the punch. Oh well. Here's what I was gonna write. Er... copy and paste?
Hello there, Fascinate people! Visitor from the Vibrant forums here. We found and tested an 1800mah battery that, while intended for the Epic Touch 4G, fits and works perfectly in the Galaxy S and all it's variants. I've personally tested it in a Samsung Fascinate and a Samsung Vibrant. The Fascinate was a tighter fit than the Vibrant, but the battery door closed just fine.
I've personally tested the battery over the past week and it lasts significantly longer than the default 1500mah battery (I'm a relatively new Vibrant user, so my battery is only a couple months old). The math seems to match up with the 1800mah claim. To be clear, this isn't as surprising as it would be if this were a random Chinese ebay battery. This battery is made by Samsung for the Epic Touch 4G. It's noticeably thicker than the stock Galaxy S battery, but not so thick that the battery door on the Vibrant and Fascinate won't close completely.
The battery can be found here:
http://www.mobilecityonline.com/wireless/store/productdetail.asp?productid=28506
I spent quite a bit of time trying to find the best 3rd party battery for my phone, and lo and behold, the best one comes from Samsung itself.
If you'd like to read more than just my humble opinion, here is a link to the thread started in the Vibrant forum:
http://forum.xda-developers.com/showthread.php?t=1262035
Hope this information is helpful. Enjoy your Galaxy S!

this battery does indeed work very well. the battery is bigger and the door does fit tight, but the door does close completely. just started using it and am noticing significant gains after 12 hours of use. I will post back after a few charge discharge cycles with current setup and screenshots.

that would fit, correct?
it says it has a usb port but does it come with a usb cord as well that would fit in my fascinate? (mainly directed at the guy who buys the batteries off ebay)

I have two of those.chargers, never used the USB port though. Mine did not come with cables though, you can use.the stock one if you wanted. I've bought 8 batteries out of Hong Kong, all OEM Samsung batteries, never had an issue or problem. Just got 2 in the mail today actually. If you have an external charger and multiple batteries there really isn't much of a reason to plug your phone in on a regular basis anyways.

There is a break in the life because the phone shut off. Its been happening since I got a new htc battery
Pyroice mt4gs

If your on the stock battery then that is normal dude.

Get either a Mugen or an Anker.
Delivered via candygram for Mr. Mongo.

I figured bit I just wanted to ask some people who know what they talk about.
Pyroice mt4gs

i have the stock battery that came with it and have great battery life on 1.0.3. Where did you get your battery? Could you have gotten hornswaggled? Also have you tryed recalibrating your battery using the advanced option in clockwork or the Recalibration app https://market.android.com/details?id=com.nema.batterycalibration

I have used the battery calibration app. Should I try doing it in recovery?
Pyroice mt4gs

I'm pretty sure they do the same thing, recovery verses recal app. If you haven't already, i would drain it completely and then let it charge with the phone off overnight to ensure it's full. and then run recalibration. In the meantime Ill pay attention to what i get on a daily average and we can compare. You shouldn't be > 70% after 3 hours doing nothing.

I'm on pyro ice with the stock battery and have the same problem. I just stay near a charger!

How long does a full charge last?
A lot depends on signal quality as well.
If I dnt use the screen too much I can get around 18-23 hrs on good signal, but worse with bad.

I've had pretty good luck with the Anker. I'm using Juice defender too. Usually make through pretty long days.

If I actually let it die I could get 5-6 hours. If I don't use it at all I get more. I called htc the guy told me its normal to get this kind of life. I think that is unacceptable.
Pyroice mt4gs

I get a max of 13hours on mine. No matter what I do I cant make it any better. On stock battery though.
Is the Anker 1900mAh battery that much better than the stock? I've seen people report at least 20hrs on heavy usage.

signal quality, background apps, also im using only one connection type at once only and switch manually between 2G / 3G mobile net.
and yes, im on anker, ordered the two + charger package... but just be aware those who have it, the UK dealer is resending me a new charger, as they tell that anker warned them its dangerous to charge through the USB part of anker charger, at least with those that were traded out in december for me...

I think when I get paid I'm going for the 2 anker batteries and charger.

I do just about the same. Flashed with the ExtremeUV kernel, though. Given our horrible network and no 4G, i usually just stick to 2G because 3G causes my phone to heat up. When am at home I switch to wi-fi. All my setcpu profiles are on powersave mode except on call.
i went through the battery recalibration process too, set my brightness setting to manual 20% during the day and 0% in teh evening.
I can't possibly think of anything else to increase those hours.
I will be ordering one of those ankers. I guess the stock battery will make a good secondary battery.

Every time you let this type of battery completely die, part of it will never work again and dies forever.
Much better to stop at 2-5% then go to full empty, you hurt your battery for no good reason.
To properly break in a new battery, you need to bring it to full, then to that 2-5% mark 4 or 5 times in a row, it exercises the cells and gets them ready to work.
This may be helpful:
Everything you wanted to know about Li-Ion batteries but were afraid to ask!
Edit:
And this:
Battery:
- Spare batteries for the MT4GS? Anker for the win!!
- Mugen Power batteries (1800mAh and 3600mAh) for MyTouch 4G Slide?
- Anker or Mugen???
- Generic 1800mah batteries from Ebay?
- Can we use Sensation Seidio batteries?
- external battery pack! Awesome!
(happened to be putting battery links together in my reference, so figured i'd toss that part in here too)

Battery Not Charging Overnight

Maybe you all can help me out. 2 weeks ago I flashed Virtuous Affinity 2.05. Coming from Unity 2.39, I did the typical wipe cache/dalvik and had no issues. But for the past week, whenever I leave my phone plugged in over night it doesn't fully charge.
I'm leaving it plugged in for at least 6 hours, even up to 8 hours at times but it only charges up to 50-70%. I have checked to make sure the "Keep Display On While Charging" is not checked, yet when I check to see what's been hogging up the battery while charging - I find that Display is issue. Though the display is off during the charge, I don't know how it could be causing it.
Below are some screen shots.

I noticed this issue when I was trying to calibrate the battery. I was successful the first time (and other issues have caused some problems with the battery (long story short: had to reflash Affinity)).
Any ideas? Thanks in advance.

How old is the battery and is the cable frayed or anything? Try using a different cable and plugging it in to your computer one night. Otherwise, its probably the battery. I would buy the battery+external charger combo in case its an issue with your usb port

The battery is the same as when I bought the phone, so 2 years old. The cable isn't frayed and I have tried using another wall charger and cable with no luck. I eventually reflashed the ROM and it seemed to fix the long charge time. But now I've noticed that the battery drains much faster now with minimal use. I do agree with you that it must be an old battery though.

Have you dropped the phone recently? I was having charging problems and quick battery drain issues that seemed to be directly related to the display brightness, and I thought it was the battery as well. I replaced it, reflashed my Rom, tried different batteries, and different chargers - no help. The only thing left is physical damage, which I looked into and found that the cost wasn't worth it.
Hopefully it's just your battery.
If you don't mind though, if it turns out to be something else, and you can figure it out, can you report back here so I may have some idea whether I can fix the issue myself or whether to start looking for a new phone? I'd really appreciate it.

I've dropped my phone a few times, none that I ever saw affect its performance. I'm not 100% sure but I know the problem is the battery. When I pulled the battery, there is a slight bulge in the towards the middle of it. So I know it is time to replace it.
Due to the timing of this nature, I was already starting to look for a new phone and ended up getting one yesterday, HTC One S. I still plan on getting a new battery for the MT4G and using it as a test phone. I don't know if you have T-Mobile but they are doing a deal that actually lowered my payment plan for unlimited everything, just have to get a new phone. In either case, good luck to you as well!

Actually, my battery had a bulge as well. Either way, it's most likely the battery anyway.
I looked at the one s myself, but didn't like the non removable battery, so I'm going to replace with the Amaze. Works well for me anyway as I'm with Wind (Canada) right now, but I'm thinking of moving in the next year or so to an area that isn't covered by Wind, and the Amaze will work with the companies that do. Yeah, I don't switch phones often - just roms...

S3 2300mAh Battery

I just wanted to share the deal I found on a spare battery with 200 extra mAh. I would imagine that this does not have the NFC chip, but I wasn't too concerned with that as of yet since I don't use any tags yet anyway. I spent a little over $3.00 with shipping for one battery. I figured even if it was garbage, I'm not out much money.

Update:
Received this battery today. It was at 68% when I put it in this morning. So far, so good. I haven't noticed anything out of the ordinary, like excessive heat.

is it safe to use I9300 battery on our device?

Even the real one that costs $44 does not have great reviews. Will also lose NFC capability that the $44 one has. Should be ok for backup if does not explode in phone.

Fishy.... very fishy... also curious to see how this pans out.

"$3.00 with shipping for one battery" = guaranteed junk

I was given one of these exact looking batteries (can't be sure of brand/manufacturer as they're un-branded but they certainly have the same sticker from the looks of the picture) and thought "what the hell... it's free" and started using it. Less than 3 days in and I noticed my phone getting warmer than usual. Didn't think anything of it, thought it might have been just from me using the phone more. About 5 days into using it the phone started getting REALLY hot when charging. Next thing I knew, while charging the phone, the edge of the battery cover "popped" and was pushed out so it unlatched from the phone. You guessed it, the battery was swollen and HOT to the touch. Hot enough where I couldn't hold it bare handed for very long. Unplugged it immediately, placed it in a heat/fire proof container to let it cool down, but it kept swelling for the next 5 mins to the point where it won't fit in the phone any longer. (Not that I tried, but from the looks of the deformation there is no way it would fit in the battery compartment.)
As they say, you get what you pay for. Why risk saving ~$30 when it can damage/ruin your ~$500 phone! Worst yet, why risk it for bodily harm to yourself or your loved ones?!! (Perhaps this can be a covert way to dispose of/harm your mortal enemies and blame it on faulty junk electronics... hmm...) I'm fairly certain that if I had kept charging the battery there would have been a very likely case of it starting a fire as it was on top of a paper book on my night stand while charging. I can't imagine how horrible I would feel if MY phone had started a fire that ended up hurting or killing someone in the process...
Moral of the story - yes, you might get a battery that works well for you and I'm sure many people have, but why risk it?? My suggestion - STAY AWAY! STAY FAR FAR AWAY!

I actually bought this
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=330768545772
supposedly 2900mah
comes with 3 batteries and a charger
Now my word of warning: I have used these china batteries before for my other smartphones. They never gave me an issue of overheating or anything like that, but dont believe the power ratings they have. it is NOT 2900mah. Its probably more like 1800mah
I keep them charged and use them in case my phone dies and I have to have a phone right away. I dont use them as my normal day to day battery.

I got two Anker batteries for $15.00. I usually only need to resort to using one of them each week, but I always have a second if needed. I believe for a few more dollars you can get an external battery charger. That takes care of the charging problem.

How about two batteries and a charger from hyperion for $20. I believe this to be a fairly reputable brand. It can be found on Amazon if you search for hyperion. Sorry, it appears I am not cool enough to post links yet.

I can vouch for them. Tested several batteries and it does have longer battery life than OEM

Haven't tested the Anker 2200 yet so I cant say for sure which battery is the best.

I might be looking into picking one up but am leaning towards an external one.

I realize that this battery most likely is not a good battery. For $3 it would certainly be a good emergency backup.

I use a seidio charge vault that was invaluable when I was on a work trip and started experiencing frequent hot boots on a previously fairly stable rom. Between trying to troubleshoot that and flashing to a backup I went through my battery pretty quick. It is also my go to travel charger.

Received this battery today. It was at 68% when I put it in this morning. So far, so good. I haven't noticed anything out of the ordinary, like excessive heat.

Extended battery thoughts

Anyone here invest in an extended battery with case and have any input on their experience with it? I have heard hyperion is good but it has very mixed reviews online and there are issues with getting a decent back plate. Comments and suggestions are welcome.

I've been wondering the same thing but if you hit up the accessories subsection you'll see a bunch of posts discussing it.

I recently purchased the Hyperion with Case and cover I have to say I'm impressed with the battery life so far. Still testing. Here are my results from first use

16% screen time? Well I can last longer on stock battery

I bought an extended battery 4500mah on ebay for $8 a couple weeks ago from ebay. It makes the phone twice as thick, but the battery lasts all day with moderate use. I haven't put my phone on the charger mid-day since I bought it. Being that its a cheap generic battery, there is no brand name and I can't verify the capacity is accurate, but it is getting the job done. I'm at work and can't really give any more specifics, but heres a quick comparison
Pros: 1 overnight charge lasts all day, phone not much heavier, GSAM app seems to accurately adapt, Thicker case seems to protect rear camera and light better without obstructing them. Makes you more attractive to opposite gender (this may be a false claim)
Cons: Phone thicker, loss of NFC chip, longer charge time, must charge from lower capacity to avoid confusing battery estimation mechanisms (under 40ish%) Harder to find protective cases, and old ones will not fit.

the gs3 is the first phone i haven't thought of buying a bigger battery for. i get great life with the stock one, much better than my razr maxx had.

I was about to buy one of these extend bateries,but making the phone twice as thick is a turn off....

Thanks for all the responses so far. What I did was buy another oem nfc enabled battery, and a phone mount charger with battery charger. I am actually getting all day charge with heavy use and switching in a fresh one before sleep. The only reason I was curious about extended was because I enjoy hiking and photography. But unless you get 2 days use it doesn't appear to be much better than buying multiple stock batteries.

i ended up getting the extended battery from hyperion on amazon.
i live in miami, and lost power for like 2 days over a month back and instantly i realized i needed this fat battery.
it actually feels better when i grip it. and i love that i forget at times to charge and its all good.
i got it for my wife since she is always killing her phone. it goes all day sometimes 1 day and half.
it's funny though because the size may turn you off but size wize it matches other friends of mine who also have the s3 and they over do it with the thick cases and stock battery.

Does anyone know how to reset the phone to give an accurate read out of the bigger battery?
Is there such a need to do so?
With these batteries the specs for a OEM battery is like days in standby. Would not one think that an extended battery would last weeks, and not drain in a day of hanging out in your pocket with little WiFi, calls, and text messages?
I know the ones they sell on e bay and Amazon are old new batteries as they have been sitting in storage and shelf live has caught up to them.
This is the only explanation for such a short time before having to recharge them.
I have never had a brand new hot off the press battery, as I get my phones at the pawn shop discounted. Hence they are already discontinued by the service providers.
I wouldn't even trust buying a new OEM battery from them as there is no telling how long they have had there batteries in stock just sitting there getting old depreciating.

I agree - stock battery is good but I bought an extended anyway for longer gaming sessions.
I use the stock battery when at work so I can use my otterbox, but in my leisure time the hyperion battery rocks. No complaints on the stock battery, liking the hyperion as well.
My complaint is losing data service under 50% battery - hyperion staves that off longer.

But does hyperion really offer more than a day these responses seem to confirm my worries of it not being double as advertised but maybe in the 1.25 to 1.75 range? And if all the stock batteries have been sitting on the shelf how would the hyperion battery be any different? I am really considering investing in a hyperion still because 3 batteries would be ownage and I generally go on hikes for 2 to 3 days and my 2 stocks might not make it. Climbing a peak and taking a panoramic is truly special. But at this point investing in a new case with a hyperion might be more hassle than buying some more oems on the cheap.
Anyways thanks for the responses everyone. And PROTIP storing your battery at 50% in a dry cool place is what is recommended for long term storage. Also I learned recently that letting your battery go through a full discharge and then recharging actually leads to a longer battery life span, by a huge factor!
PS sorry admins and others I just joined this forum and realize this whole thread should have been placed in the accessories section I hope my gaff does not make you think less of me.

Well first remember 16% becomes a larger number when you have more capacity also there were several other items being used. Also this was the first tinting charge of a cycle. The phone talk time ended up over 4 hours or so as well also I need several restarts. I am happy with it

This is with the Hyperion extended. I would recommend it.

Hyperion extended battery after a few cycles

How is everyone getting 24+ hrs with the Hyperion?? I seem to be only achieving 12+ hrs with almost 6 hrs of screen on time (wifi on, brightness 30%, sync on)!
