[Q] Mugen Battery strangeness...

This is my first post on here,but I've been lurking for ages I just bought a Mugen 3200mAh battery from MugenBattery.com.I already know about not having to condition it(lithium ion),so I ignored the instructions about cycling it and plugged it in and used it right away,and at first it seemed okay for around an hour(I didnt use it at all up to this point,just left it there until I needed it).When I went to unlock my Vibrant from suspend(pushing on the power button),the phone shut off and seemed like it was rebooting...but it just had the first screen you see(the one with Samsung and Vibrant on it) blinking on and off,even when I plugged in the charger in this state,all that popped up was a battery that also blinked on and off.The only way to get it going again was to pull and replace the battery,and it went back on again...then did this all over again when it went into suspend and I tried to unlock it.All the while,the battery stated it had around 75% power,so I have no idea what could have caused this.I put my cheep chinese 2700mAh battery back in and all was well again,so I know its the battery,not the phone.Anyone else have or seen this problem before?This is the most expensive battrery I have ever purchased for a phone at $88.00US....I hate to think that a cheep($20.00US) chinese battery has better quality control than it....

i think you need to charge it for 12 hours first.

Thanks,you were right! An overnight charge of around 12 hours did it.This is the first phone battery I had to do that with to get them to just work at all.Seems to work just fine now Again,thank you!

Let us know how long the battery is lasting once you get a few cycles please!

Yeah, you should run the battery dry, recharge, run dry, recharge and after a few cycles your life should improve.

Will do,just need a few days to do it,its lasting a looooong time!

NO, NO, NO. PLEASE stop spreading bad information. This will HARM the battery, and will have 0 benefit. The only "benefit" you can get from this is that the battery meter on the phone's firmware will be calibrated to show a more correct remaining %. You can achieve the same by charging the phone 100% (overnight) going to clockwork recovery and selecting 'wipe battery stats'. Calibrated or not, the battery will last the same, regardless of what % left its showing.
Again for posterity, REPEATED DISCHARGING OF LI-ION BELOW 20% IS BAD FOR THE BATTERY, IT'S PHYSICALLY IMPOSSIBLE FOR IT TO GET BETTER.

I am having a similar issue with a battery that I ordered off of ebay. It's 3500mah.
When I plug it in it will turn off and get stuck in a boot loop on the vibrant screen, but if it is off then it won't turn on at all when plugged in. It has been plugged in for 9 hours so far and it doesn't even show the charging animation or anything.
Normal? Or is the battery defective?
Thanks.

Ok. After charging it overnight and still nothing, I'm going to assume its broken. Thanks.

Not to derail, but how much weight does it add, and how well does the back cover fit on that big Mugen?

it fits good...

...and it does get a bit bulky,weight goes up to about double the amount,but it is so worth it,and then some!!I went from 6 hours on the stock battery to over 18 with the Mugen,and thats with heavy use(full brightness/live wallpaper,etc.).If you dont have access to a charger outside your home,this is a great buy,and you know the quality is there,unlike the uncertainty of the cheep chinese ones.Highly recommended!

The OS needs to learn your new battery. Just takes time and usage.

just bought 3000 mah
just bought one from accessory geeks, it came 70% charged, and am updating battery stats after a full charge, during stat recalibration, power is iffy. will update, and am considering mugen. any suggestions?

I am not so sure about your information

I am not so sure about your information. This is what DHGate, a wholesale Chinese online store wrote about the 3000mah battery for Galaxy S [not MUGGEN!]
How to use a new battery:
1. First when you received the battery,. you need to release the power in the battery, just put it into your phone without charging.
2. After the battery power is out, please charge it about 12 hours in first three times.
3. So the battery will be actived. So you can just charge it about 5-7 hours when use in the further.

No controversies at all. Your info from the link is outright wrong.
Mannymal is correct on this one.

I also have this battery. By the time I got it, Team Whiskeys roms had gotten good enough to where I didn't need an extended battery for day to day use (stock battery usually has 30-40% when i go to bed), but I do use it when I travel, so I don't have to worry about using it like crazy. The battery lasts a long time, probably like 2 or 3 days if I actually tried to drain it, at least. And it's definitely adds bulk, but it's reasonably well made and feels sturdy.
My only complaint is that I sometimes cover the speaker with my finger when I want to silence it real quick, and it doesn't work with this because the cover's so far from the speaker. But that's just my weird thing.
Also, yeah, don't kill your battery. No es bueno.

What is this? How do I read?
What is this? How do I read?

I use a seido innocell battery and it works great after a few over night charges. I get about 8 hours average of talk time. The battery is pretty small compared to the one accessory greeks sell. Even though the ah battery ia twenty five dollars, that is like the entry level name brand battery, it will lady you a while longer than the cheap ones on ebay, but I don't knower about the ones on ebay although I do know about the one ag sells skies down charging after about 45 percent charging. The seido is charging pretty fast for me and is half the price of a mugen, the next battery I'm going to buy will be the nugent, not because I need it, just
Cause I want to enjoy it.

Warning about fastboot on Evo

Just want to give everybody a heads up about fastboot on the Evo. First I'll give a little background of the things I have done with my phone.
Root & Nand Unlock
Running CM7 Nightly build #26
Custon Splash Screen and Bootloader
Nothing special about it but it was a work in progress..
Now onto the warning.
I had my phone in fastboot mode working on pushing a different Splash Screen to my phone when I realized that I was late for picking my girl up from work. Looking back now this was a dumb idea, but I decided to just leave and pick her up and I would finish when I came back. Meaning that I left my phone plugged into the computer in fastboot mode and I had the command prompt up as I was typing in the code to push the image. When I returned home my phone was off. I also realized that the charging light wasn't on. I tried turning on the screen and nothing. Tried booting into recovery and nothing again. So i decided to unplug it from the computer and plug it straight into the wall hoping that might help. I was wrong. 30 minutes later still no charging light at all. Not even blinking. Not exactly sure what caused the bricking of my Evo. If it was leaving it in the fastboot screen to long, having it plugged into my computer, having the command prompt up or maybe a combination of all of them.
So moral of the story is don't do this lol.

Wow, sorry to hear that. Have you tried removing the battery for a couple minutes? then put back in and plug in to charge?
My sisters phone was absolutely dead and wouldnt come on and no charge light. It took several attempts of pulling the battery, re-inserting it before the charge light came back on. (If im not mistaken the phone does not charge in fast boot, so maybe your battery is super dead like hers)

Yea, I would definitely try a known good battery before letting your Evo RIP. Sometimes li-po batteries get dead to the point that they wont take a charge.

Fantastic call!!!! My girl also has an Evo so I stole her battery and put it in my phone and presto it works just fine. So now I have my battery in her phone on the charger. It has been a little over 2 1/2 and still nothing. So I am thinking that the battery might just be permanently dead. If that's all that happened then I am satisfied. I can handle buying a new battery but I really didn't want to get a new phone. Thanks to both of you guys "elegantia" and "k2buckley". I appreciate your posts

Glad to help, and glad you got it going again! What a relief for you! Yea, these batteries don't like to die completely, despite what some people say. The fact is, lithium polymer/lithium ion batteries don't like to be drained to 0. But at least it's just a bad battery. Check on ebay, I've heard good results about some of the cheap ones on there. And best buy also has a 1750mah battery, that is the same physical size as stock, but has a little more juice (stock is 1500mah). Good luck.

You can pick up a brand new OEM battery off of Amazon for $13. I'd go that route before the 1750 mAh batteries off eBay. The tests I've seen show they actually have less capacity than the stocker.
Also, this may be kind of pseudosciency but try putting the battery in the freezer for a few minutes and then popping it right on a charger.

It's so wierd because my phone was fully charged when I left the house. So unless fastboot drains your battery like "super quick" I am shocked to say the least. I'm willing to try anything with the current battery I have so I might take the advice of "eventer289" and throw it in the freezer and then on the charger. Not sure what I will do yet if I have to purchase another battery but one thing is for sure, my girl is definitely not going to let me keep her battery so whatever I decide I am going to have to do it quick lol. Thanks again for all the advice

Let me know if it works. I've read about the freezer thing to revive lithium ion laptop batteries, so I figure what the hell, give it a shot.

Your battery got to low and that's why it won't charge it, I had the same thing happen to me last week. I just cleaned up my phone using my spare and took it in to sprint with the bad one back in it. They gave me a new one for free.

My girls phone isn't rooted. So I might just take hers in with the battery and do this. Not a bad idea at all. Thanks

Update- Have had battery plugged in for four hours now and nothing. So final conclusion is that the battery is shot!!! Sprint, here I come lmao!!

yes.. take it to sprint.. you have 1 yr warranty..
99% sure they will just give you a new battery. if they have one!

That's wha I'm hopin

The problem is, I think in certain modes - such as fastboot, the charging code isn't present. If you leave the device unattended, it drains and drains, even if plugged in (notice no charge light in recovery mode either, when plugged in). As stated, if the voltage falls too low, it won't accept a charge. There's probably some way of reviving the battery, but why bother. Hopefully the OP learned his lesson.

Lithium chargers have a built in safety that will check for minimum voltage before attempting to charge the battery. The EVO has this safety mechanism built in. The method to bring the battery back is to charge it in a dumb charger until the voltage reaches high enough for the EVO to recognize it as a proper battery and then charge it. I've never had to do this on a mobile battery but have done it a few times on Lithium Polymer packs for R/C planes. Some cheap Chinese chargers don't check voltage before charging. You could try jumping the terminals from a good pack to the dead pack for a few minutes being careful to jump the exact same terminal on both batteries. It's worth a shot. Excessive discharge can ruin the battery life going forward but you won't really know until you try. I would monitor both packs for excessive heat just in case but in all likelihood you'll be fine connecting them for a few minutes to boost the voltage on the dead pack. You can always get a two pack of batteries and an external charger on eBay for around $20.

^^^^ good info.. on why it is not taking a charge

Probably should change the topic now since this has nothing to do with fastboot. Simply having cmd open with stuff typed in it won't do anything to your phone.

[Q] Battery - should I charge straight away, or let it run down first?

I'm not up-to-date on battery etiquette, so thought I would check with you chaps. I should be picking my One X up from Carphone Warehouse tomorrow or Wed, but wanted to know whether it was considered better to charge immediately, or to use the battery until the phone dies, then charge fully, or some other third option. Want to make sure I get the best out of the battery, obviously.
Thanks!

What you really want to do is condition your battery. You don't need to do it immediately but in the first week or so of having the phone. By conditioning, I mean... Charging it until it's full, then using it until its fully discharged, then charging it again. Repeat this cycle ("fully discharged when charging") for 3 to 4 times... after that, you'll notice that your battery lasts longer than usual. It's what I've done with all my phones, seemed to work pretty good.

But were you using Lithium-Ion batteries? From what I have heard, completely depleting the power of the battery actually damages its health.

A lot of the time android will shut down just before your battery is 100% empty, you will find if you try to turn your phone on after its shut down it will still boot and run for 15 - 30 mins, depending on battery age and condition ofcorse. And if you keep on turning on the phone when its battery is very low/empty you will then start to damage it.

How to Prime Batteries
...Rechargeable batteries may not deliver their full rated capacity when new and will require formatting. While this applies to most battery systems, manufacturers of lithium-ion batteries disagree. They say that Li-ion is ready at birth and does not need priming. Although this may be true, users have reported some capacity gains by cycling these batteries after long storage....

Conditioning the battery was needed with old style batteries.. new Li-xxx batteries don't need one.. and what does an extra 30mins actually mean to you ...
now you can buy original replacement batteries for 20-30$, so if it loses it's capacity after some time you can easily buy new one...

I'd use the battery as soon as you get it until completely drained.
Then perform a full battery charge without use, its best to do this to ensure a full 0%-100% charge.

And quite a bit more expensive. The only real difference I see is the charge rate. IIRC I read somewhere the Mophie covered the power button and I use the IR blaster. Either way ill give this one a shot, if I dont like it ill check out the Mophie.

The output of 500mA convince me not to be a guinea pig for this case.
I'm convinced that's just not enough power to charge up the phone while in use. Also that rate of output I'm sure it will take hours to change a phone.

I dont need it to charge. I just need it to sustain power. If both the phone and case are full just turn the case on so it discharges first. Its perfect for me, itll keep my phone topped up while im at work and not using it much.

The phone should stay charged if you don't use it much even without the case. I'm not sure what's the purpose of having a case if you're not using the phone, it will stay charge while not in use.
I personally need the case to be able to charge my phone up or hold charge while it's propped up streaming a baseball game with the AtBat app.
But I know for a fact 500mA just won't be enough power for the phone to hold a charge while in use. You will actually get power drain while in use.
Either way guys let me know how it goes I'll keep an eye on this case.

No offense, but what's your problem with this? Batteries drain when in use, period. If you're using a battery case, then the batteries are still draining. If I wanted to actually charge my phone, I'd use an external backup battery or AC-- I'm ordering this case to extend runtime by slowing consumption rate.
It just seems like you'd be better suited with an external battery.

I don't think you used the mophie juice pack before because it actually charges up the phone while you using it. That's a feature I actually need because I will actually watch a baseball game or two while at work and don't want to be tied down to a power cord.
With the Mophie case I get 2 full charges and what ever time it took the case to fully charge the phone. Needless to say I'm cordless for a whole day with heavy heavy usage and constant screen on time.
I want this case for the simple fact it has a kickstand but besides that what's the point in having this case if all it does is charge the phone while not in use. And it does a poor job at that too because it takes up to six hours to get the battery fully charged if you don't use the phone.
Does this case actually extend usage by slowing consumption rate? By how much is the question. I don't think much with the .500mA out put.

I don't think you used the mophie juice pack before because it actually charges up the phone while you using it. That's a feature I actually need because I will actually watch a baseball game or two while at work and don't want to be tied down to a power cord.
With the Mophie case I get 2 full charges and what ever time it took the case to fully charge the phone. Needless to say I'm cordless for a whole day with heavy heavy usage and constant screen on time.
I want this case for the simple fact it has a kickstand but besides that what's the point in having this case if all it does is charge the phone while not in use. And it does a poor job at that too because it takes up to six hours to get the battery fully charged if you don't use the phone.
Does this case actually extend usage by slowing consumption rate? By how much is the question. I don't think much with the .500mA out put.

Different users, different use-cases. "Not in use" means different things to different people, and my phone consumption is tweaked to be pretty low. As is I usually get through the day with about 30-50% left at the end; while I'm walking around at work, it's just playing music or I'm using a tablet to watch video instead (since I don't want to use my work machine for that...you can guess why ). Since my phone cycles down a lot of the time, 500mA is enough to trickle charge when I need it, and slow usage (by the USB charge rate, which is hardly shabby) when I am.
Since I don't need to use my battery aggressively, there is certainly a point for my use-case. And I really can never see a situation where I would want to charge my phone completely. If I really had to, I have external batteries for tha.t

Source for GOOD batteries?

I'm getting pissed with all the POS oem batteries for the S3 these days. Is going to Samsung direct my only option to get a GENUINE one? I don't see where they sell them and I don't trust eBay based on experience.

I know you can get them at Office Depot. Or you could at least, several months ago.

Pick up some Anker 2200s on Amazon or similar store.
Who cares if battery is OEM? Just get one from a reputable company.

I care. My experience with oem batteries has been miserable like many others.

Then don't buy an OEM battery. Buy Anker instead.

Zero Lemon is another good brand. Try this Amazon Link.

Tried them. They suck just like the others. The contacts on Ankers wear out more quickly too.

Great I'll look into it.

Are you certain your issues are the batteries and not your setup and use of your device?
There are lots of things that can lead to miserable battery life even on the most solid of batteries.

Yes I'm certain. The genuine Samsung battery lasts much longer than the poor ones.

I don't think that was Doc's question. I think he wanted to know if you are experiencing poor battery life due to the batteries or some issue with android setup that's causing immense drain ?

I guess I'm confused. If the same phone is used in a manner consistent with whatever battery is used, what else could the explanation be?

Basically, you started down this path due to a drain on the Stock Battery right ? Would you be able to shed some light on that ?

Sure. Brand new phone just purchased. Very few programs installed. Battery used was purchased off eBay. When indicator light showed fully charged I unplugged. Battery remaining went immediately from 100% to 88%. After 6 hours of light use, battery was already down to 40%. Within 20 minutes it fell off the cliff and phone turned off ... basically fully discharged.
Next, stock battery installed. 1 day 12 hours later battery still shows 55% remaining.

In that case I'd recommend Monster ZeroLemon 7000 MAh again.People here on XDA have really tried to suck every drop of juice out of it. It had stood all that abuse very well. Buy it from Amazon so you have solid Return Policy in case of trouble.

Thanks, I'll seriously consider it though the added thickness is a concern. If I could get 2 extra batteries close to the performance of the stock battery and at a combined price close to the ZeroLemon I would be satisfied.
How long does it typically take to charge one of those monsters?

I don't think their form factor would have issues with the SIII's casing.
I do believe they take roughly 4 hours or so with Samsung's original Charger. I don't have one myself so I have second hand information. It is true that if you have a Fast Charge Kernel, this is further reduced. I am guessing, if you charge off of a PC, of course it will practically take forever to finish :laugh:
My 1 year old stock battery goes me 3 days if on Standby all the time.It will last 1 & 1/2 to 2 days if I use conservatively.

Just fyi, fast charge kernels only make a difference when plugged into a PC and maybe a DC (car) outlet. And correct that the batteries should be the same size and ought to work fine. Only real thing to make note of is if you use any NFC features make sure the battery you get has this capability.

Bit OT here, but my regular Kernel KT747, now (in recent version) has special code for the 11th pin of the MHT port. So I am given to understand the Fast Charge thus implemented actually affects the way it charges off wall. I am testing since yesterday.

The theory behind fast charge kernels is that when you plug into a PC it detects the data connection and limits charging to 500ma or so. Fast charge kernels allow you to disable the data connection, thereby fooling it into thinking it's plugged into a normal charger and bypassing that limit.
The extra pins don't have anything to do with charging. Only 4 of them do. Before fast charge kernels were introduced people would sometimes short two of the wires in the connector (usually with solder) to accomplish the same thing.
As I understand it the 11 pins are just used with the MHL adapter for HD output. They don't have anything to do with charging. Otherwise a basic USB cable probably wouldn't even work.
I believe there are a few in depth write-ups about fast charge kernels here on xda if you want to search for more info on it.
