3500 mah monster battery

Stay away from the Chinese monster battery, at first i had noticed phenomenal battery life, but after 2 months of having this thing, after around 8hrs my phone will just shut off, and the battery has plenty of juice. Im not sure if its something i did with my rom, but today i oden'd back to stock eb13 and updated via sprint o.t.a to ec05, and im running all stock again and my phone just shut off again. After turning it back on i noticed my battery was 76%. Im not sure if its anything with my phone, but tomorrow im swapping back to my stock battery to see if my epic still intermittently shuts off. i will post an update tomorrow. Till then i would advise others who have had the battery for more than 2 months to post their experience for everyone else.
[Epic 4G Accessories] muyoso:
Never had that happen. The only.thing I can think of is that maybe your battery is losing contact momentarily with the pins. The back is a little loose and there is a small amount of room for the extended battery to flop around. I just put two layers of duct tape on the inside of the back cover and its snug enough for the battery to have no movement. Also, try wiping off the contact points on the phone and the battery to make sure they are clean.
[Epic 4G Accessories] gregory15:
So... I was tickled to death with the battery too .... and late last week I switched back to stock because my phone just turned off several times per day. Even corrupted my mms and other things on th phone. Rebuild. So... I agree I think its a design issue causing loss of contact or a short somewhere. But... I am NOT happy with my purchase now.
[Epic 4G Accessories] nfamisnme:
Yup surprisingly enough I went back to my stock battery and I've had no issues, I sold 2 of them to some coworkerswho are running their epics stock and they haven't had a problem. I'm wondering if running custom roms may have played a critical part in corrupting my battery. I'm sure maybe a dev. Can elaborate more on this and possibilites of why the battery is faulting.
[Epic 4G Accessories] alextt58:
Check the voltage of the battery with a load on it after the 8 hour span. Its possible the voltage is dropping below the acceptable range of the DC-DC converter inside the phone.
[Epic 4G Accessories] KennyG123:
Did you ever drop it? I dropped mine and think there is a hair more room between the battery and case now so the extra back weight of the battery can cause it to pop out enough to lose contact. I added a small piece of cardboard (real thin) between the case and battery and have no shut downs anymore.
[Epic 4G Accessories] gregory15:
I totally get what u r saying. I heard of the dude who put a piece of electrical tape to tape out the slack. I am going to try and I will post back. I'm on vacation this week in Hilton Head and I'm hating the stock battery and half a day of life with gps rolling. Thx.
[Epic 4G Accessories] muyoso:
Yea, what I did was take the back cover and put 2 layers of duct tape on the part that actually touches the battery. 2 layers makes it snug without making the back hard to put on.

Here is a picture:
[Epic 4G Accessories] CardnalSyn:
Those ebay batteries are crap. I bought two regular batteries with the saame lable because i wanted to just swap batteries and still be able to use my norman case. Everything worked good for the first few months but then both of the batteries would last no longer than 4 hours. And to make it worse, i had misplaced my OEM battery. I had to trash em and buy another OEM one. This sprint rep was kind enough to sell it to me for $10,
[Epic 4G Accessories] muyoso:
So not only are you talking about different batteries than the one in question, but then you admit to getting a few good months use out of the batteries. . . . . . . And they are crap . . . . .
[Epic 4G Accessories] iviyth0s:
And stop spamming about an overpriced battery ;)

I bet the Seidio cost ya more than three of the cheap batteries too :rolleyes:

Seidio BETTER be a better battery at the extortion they call a price

I second this, batteryboss has called out Seidios cheap BS before, I want to see the Epic's version brought to justice.

Mugen is in the same boat as Seidio, ok batteries at prices far above what they should be at.

This thread is awesome though, I have bought two different cheapo extended batts for my Hero and they work great. I even have two OEM extendeds I bought for cheap recently and they are a little better but not worth the price they used to cost ($13 now). But I'm glad when I switch to the Epic that there are nice extendeds available that wont bend me over like Seidio/Mugen batteries, hope Samsung makes an OEM ext also!
[Epic 4G Accessories] eigerzoom:
i was just posting a link for the EXTENDED BACK DOOR...not the actually mugen battery...
[Epic 4G Accessories] iviyth0s:
I know, I wasn't attackin' ya but just letting people know that because you mentioned the batteries at the end.
[Epic 4G Accessories] Art2Fly:
So for clarification, yay or nay on these sub $20 batteries?
[Epic 4G Accessories] muyoso:
Thats for you to decide. I've gotten 5 months of use out of mine so far and its still rocking. Under 20 bucks to double your battery life is a pretty good deal in my book.
[Epic 4G Accessories] iviyth0s:
Yeah if they're anything like the chinese batts I got for the Hero they are definitely worth it!

I just got my Epic this morning, gonna go rootNrom it now...I'll probably pick this up eventually my dad is giving me his two normal capacity chinese batteries since he's Mr. OEM so I'll ride with those for a while and get the extended later on!
[Epic 4G Accessories] CardnalSyn:
Did u read through ur own thread before replying? Or just skim through it? i got 2x 1200mAh batteries. U have 1x 3500mAh, which is really the 2 1200 wired together as someone indicated earlier in this thread. My batteries have the SAME LABEL as the one referred to in this thread, just a diff rating. So yeah, same batteries. And yeah, 2 batteries lasting only 3 months before i have to trash them is crap. Other ppl are having issues with theirs also.
[Epic 4G Accessories] iviyth0s:
Did you contact the seller?? They almost always refund your money and let you keep the battery, that is what they did for my when i showed them this:

http://batteryboss.org/

I had submitted my battery for testing, I believe it improved during my usage I think because it's well over twice the OEM battery.

I know this isn't related to the Epic specifically but just trying to help with your situation.

Just contact the seller and I'm sure he'll/she'll hook you up
[Epic 4G Accessories] muyoso:
I absolutely never had this issue, until that is you posted this. Actually it first started happening after I updated to ACS 1.1.1, which I thought was the source of the problem. For some reason, when I really push the phone, ie. playing pvz and streaming music, the phone will get unstable and just restart. As of right now, I am unsure if this is only happening with the extended battery, but I am thinking it is. I am on the verge of just buying another one since there are US sellers on ebay basically giving them away for 11 dollars shipped. 5 months of use for 11 bucks isn't terrible. Wish someone would do a full fledged review on the seidio one though, as I would actually consider laying down the ridiculous price for it if it ACTUALLY had near 3300mah capacity.

Edit: I highly doubt this will fix anything, but I just remembered that after updating to ACS 1.1.1 I never calibrated the battery, which I religiously do when updating roms. I really don't think it will make a difference, but I will try it out over the next couple of days and see what happens.

Edit 2: Also, I run OC'ed at 1.3ghz, which probably is majorly contributing to the problem and probably the root cause of the problem. I will see if I can reliably get the problem to occur and then test a few things out, such as maybe not running at 1.3ghz. . .

Edit 3: Also noticed that the contacts on the battery were a little scuffed/dirty. Cleaned them off professionally by mashing a toothpick against them until they no longer looked scuffed. Can't hurt I guess:p
[Epic 4G Accessories] iviyth0s:
Let us know, I'm still running the stock and a backup chinese normal size battery.
[Epic 4G Accessories] muyoso:
I gotta say, I've been trying my hardest to make it happen again and it just won't. Alszso it feels like its lasting longer as well. The ONLY thing I have done so far is clean the terminals of the battery crudely with a toothpick.

I also ordered another one last night that will be here next week. Couldn't pass it up for 10.59 shipped.
[Epic 4G Accessories] iviyth0s:
You gotta buy me one too Mr moneybags :D
[Epic 4G Accessories] muyoso:
So after cleaning the terminals it ran great for a full charge. Far away from claiming this is the cause, but so far so good. Also, can't hurt to clean them.
[Epic 4G Accessories] Jackalo:
I bought one of these batteries when I noticed this thread back in January. It's been working great for me. I use my phone quite a bit throughout the day with Exchange email, web browsing, and the occasional game on my lunch break. The stock battery would be almost dead or completely dead from 6am to 5pm (time off of the charger). This battery is generally at 60% or a little less by the time 5pm rolls around. Also, I've got big hands so the added thickness makes the phone more comfortable to use.

Thanks again for sharing the info with all of us, Muyoso. It certainly made a difference in my daily routine. :-)
[Epic 4G Accessories] muyoso:
No problem. Glad I could offer what little I can to XDA, because I certainly am not a developer.

On a separate note, gone fully through the second charge after cleaning the terminals on the battery and it still hasn't rebooted the phone a single time. Anyone else with the issue try this yet?
[Epic 4G Accessories] muyoso:
Just got the new 3500mah battery I ordered, and damn I am liking it. The back fits SO much better and is nearly impossible to get off once you snap it in. It will probably loosen with time, but damn there is an audible click when you snap it on. I took the sticker completely off of the battery and there are zero markings indicating the size of the cells. This is what I ordered and who i ordered it from:

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=150613073015&ssPageName=ADME:L:OU:US:1123

It took 5 days to get to my house and I ordered it on a Friday, so not bad at all. After a few charges with this new battery I will probably do some testing on it to compare it not only to the stock battery but also the older extended battery that began this thread.

Edit: First charge of the new battery has given four and a half hours of screen on time. Looking pretty good.
[Epic 4G Accessories] thegameksk:
Ive seen some threads that say the Seido case can hold the phone with an extended battery in it. Where can I get this case from? Ive only seen one case on the website and it doesnt say anything about fitting an extended battery
[Epic 4G Accessories] myerk2008:
i just bought this battery last night waiting for it to arrive then ill set up the true math for everyone and the one i order is the same as the posting of it but got it for 10$ plus 5$ for faster shipping so after i finish the math ill let everybody know
[Epic 4G Accessories] iviyth0s:
True math?? Do you have lithium ion battery testing equipment?

I hope he does. That would be amazing. I know the math I did in the OP was pretty rough.

[Epic 4G Accessories] Robbzilla:
Could you post a side-view pic of the battery, installed in your phone with the cover on? I'd like to get an idea of how thick it is.
[Epic 4G Accessories] iviyth0s:
So far so good, can't copy on the battery life yet but I really like the feel of the bulge and it still fits in the sleeve I carry it with and my pocket no problem.

I know it doesn't look like it but the case is actually a tiny bit smaller than a quarter's full diameter by maybe 2mm
[Epic 4G Accessories] iviyth0s:
This battery is amazing!! Probably a better performance increase than I saw when buying the cheap extended battery on my old phone!!

I will go buy another for $7 in my state and then never have to plug it in again :D

I have a question for you guys. So I just bought one of these 3500 mah batteries, and while I'm not expecting miracles...I installed a battery widget and it said the total available mah is only 1200 mah! Is that normal or did I get a dud? Anyone else tested these batteries this way? Thanks

From cellblock D
[Epic 4G Accessories] iviyth0s:
Did you charge the battery extensively prior to usage?? My real usage has proven it to be noticably better than the OEM 1500MaH. It may not have any high end internal circuitry to report its correct capacity may be all.
[Epic 4G Accessories] Zor Omega:
I let it charge for 10 hrs. I'm running on my first discharge now though, so I can't comment on real world usage yet. I'm sure it will take a few charges to break in. was just wondering if anyone else had noticed this.

[Epic 4G Accessories] unitmonster:
My experience so far...I bought the battery above (see post 222) about 2 weeks ago and am absolutely loving it. With moderate usage (autosyncing, mp3 player, websurfing, texting, some calls) it can easily go 30+ hours. With light usage I have pushed it over 48 hours. With excessive usage it can still go for a good while. I recently used the GPS for a 4-5 hour roadtrip while also using the phone as an mp3 player (plugged into aux input of car) and it lasted the entire trip with some battery left. My stock battery never would have done that for me. As an fyi, I am on SRF 1.2 rom.
[Epic 4G Accessories] iviyth0s:
Yup, I can't believe how good they are.

I just bought another today so I can have one on the charger and never have to switch back to my stock batt anymore

In battery monitor widget you have to calibrate the battery (actually the phone) when your on the main screen of the app, likw after you tap the wiget and see the graph(s) hit menu key and go to menu>settings> and scroll down to "battery capsity" and enter your capsity in mah, for stock it would be 1500, for yours it would be 3500... hope that helps

I just hit thanks for your review. I bought one and at first I thought it was strange and big but I did get used to it quick. The battery lasts really long, at 79% left and its been 8 hours. Not bad for $7.99!!! Now only time will tell how much the life will degrade over the months to come.
[Epic 4G Accessories] Zeinzu:
People do realize that the "battery calibration" argument was indeed settled right? There's no such thing as calibrating a lithuim ion battery. This came straight from a long standing google engineer. Any difference you "think" you see is varying differences of usage, polling, pushing, connection strength, wakes, and pretty much a million other factors that will "always" change your day to day battery life.
[Epic 4G Accessories] XxLostSoulxX:
Ehhh it goes 50-50 mixed reviews i can tell you personally i've ran my phone one day and repeat same process nothing different once with not calibrating and it once with and when it was so called calibrated it lasted a bit longer I.E. i got 4+ hours.

Today i just used GPS for 2 Hours, Screen on time for 1.5 Hours, and Screen Brightness Full, and not calibrated completely and got about 8 Hours.

I know on other battery same mAh rating. if i used 2 Hours for GPS i could go from 80% to 30% if not calibrated if i was calibrated ii would go from 80% to 45%.

It just all boils down to what you think if its truly improving if you do it right is all. but that's just My Opinion.
[Epic 4G Accessories] Zeinzu:
Everything you just said is mute so I hardly read it. I'm going to go ahead and just say it. A long standing google engineer knows a whole lot better than you "and" I, so your "opinion" of what you "think" it does or doesn't change is absolutely meaningless.

FYI what do you believe deleting batterystats does? I'll tell you... it deletes the battery statistics that are saved for your viewing pleasure under settings/applications/battery usage. The same thing happens each time you reach full charge. Aka your "calibration" is simply deleting a text file that shows you the info on what used up your battery on your last/current charge. I'd love for you to explain the science of how deleting that file can alter your battery life, cause obviously you know something technical engineers don't.
[Epic 4G Accessories] DaggettBeaver:
Yeah, I just got mine for about $7. Only had it two weeks, but it's working great for me. If it performs this way for at least 4 months, I'll be thrilled.

It doesn't matter but then why is it even on the extended batteries they all say Fully discharge and fully charge it up 4 to 5 times. i bought the hyperion just a bit ago and the 1st cycle was ok, 2nd last longer and 3rd was much better. And i dont care if an engineer says it doesn't affect it. Because when I "calibrate" it it lasts longer no matter what you say it lasts longer i do it every so often and get better results. Do what you want but when i can do a day plus and have some decent moderate to heavy usage. so get over it. im not trying to be rude im just giving MY opinion. i appreciate your opinions so theres no reason to get like this.

Ill have to check tomorrow i mean i used GPS today so i started out with 100 but dropped because im on NO UV, NO OC @ 1000MHz Lagfree so its constantly running @ 1GHz so its not bad to get these results. last night i managed 18 hours.
[Epic 4G Accessories] Zeinzu:
Cycling the battery is different. Your working in the cells, like how you would excersise a muscle. If you completely dispense the charge and fully charge of course your going to see better results, but your also going to shorten your batteries overall lifespan, this isn't "calibrating" a battery though. I'm going to say this again, explain to me the technical science behind deleting a text file that's only purpose is to record battery info on what's been using your battery so it can display it for you under settings affecting your battery. And please stop with the "I don't care what a google technical engineer says" crap, please. Your basically trying to claim that "you" know better than someone who went to school for, has worked in the business of, and directly works with the engineering of the os and devices you hold in your hand. You do "not" know better than said person, regardless of the meaningless "opinion" you carry. Your like the guy who has someone lay out infront of you proof that the world is round and your like "**** you it's flat cause I said so" rofl.

[Epic 4G Accessories] Zeinzu:
You absolutely can "condition" a lithium ion battery. Take notice to when a battery is used far past it's life the battery (internal cells) expand and the battery fattens. Most people however will replace their battery long before that, and mind you the more you "condition" it the more your shortening it's lifespan (cycles). It's only necessary to cycle (condition) a "brand new" battery for this reason. 4-5 full cycles to ensure it's holding it's max capacity on a full charge. Any further cycling (conditioning) for the that purpose is only shortening the total lifespan of the battery.
