[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.

...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.

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.

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.

Sieidio Battery 1750mAh Extended Battery Review

I purchased the Sieidio Battery 1750mAh on Amazon about a month ago. This battery is not worth the money at all. If you want an extra battery then I suggest buying an OEM battery.
I might be wrong but I think this battery actually goes down faster than the one that came with the phone. My biggest problem with this battery is that it does not fit properly in the phone. It can just be set down or place in my pocket and that is enough to make the phone.
DON'T wast you money on this battery

I don't even understand your review, but I guess I do understand you are being negative.
But this battery works way better than the stock battery that came with my EVO. It ****s on the stock battery. Diarrhea.
Maybe it's just because I bought it for $50 from Best Buy. What a bargain!

I got two 1800mAh batteries for about $30, and experienced the same thing. After awhile though, I realized that you have to do a few things to get better battery life.
1) Charge the battery to full while the phone is on.
2) Unplug and plug back in to verify that the phone is fully charged (green led)
3) Turn the phone off
4) Unplug, plug in, and wait for a green led
5) Repeat that 5-10 times
6) Then while still plugged in, reboot into Recovery and wipe the battery stats via the advanced menu.
7) Reboot, and use your phone as you normally would.
This may sound like alot, but it really only take about 5 mins. Even after wipe, it will still take about 5 full discharges to reap the better battery life. Hope this helps!

I think its just luck of the draw on aftermarket batteries (the cheap ones at least)
I have heard good and bad on ALL of them.
I got the Chichitec/htcexpress 1800 batteries with charger. Came in the other day and I couldn't be happier. 14 hours on initial charge, that's unheard of for me. On my stock battery I had to keep the phone plugged in most of the day at work just to still have juice by the time I got home. And supposedly these things start acting even better after a few charge cycles.
(Fits with stock battery door too)
But for every person that has a good experience with any of these companies, there's someone else with a horror story.

Could have told you that before you bought it, ratings by aftermarket reputable companies are close and never accurate...if they rate it at 1750, it's probably 1500-1650... The stock is 1500 so yes you wasted your money. Now on the other hand, the 3500 is the best investment anyone could ever make....

It's been proven long ago seidio over rates their batteries. The "1750" is actually just under 1500, so less capacity then the stock battery.
Sent from my PC36100 using XDA Premium App

just terribad in my opinion, gonna stick to my seidio 3500. rather have the size and life than a small size and a measly bump from the 1750mah battery

They rated it less than a 1500 stock battery.

Key with extended batteries is that you actually have to charge them longer than your phone indicates.
Example: I phone said it was fully charged at 3:26am in the morning. Yet it continue to charge until at least 6:45am before it was constant. Granted I am using an SBC kernel but even without, you need to let it charge the night. Don't let the green light fool you. It takes a few extra hours to charge even if the led light is green!
You should just about fully drain your battery and then let it charge overnight. If you aren't on an SBC kernel you may actually want to charge your phone while it's off so that the battery dictates the charge.
You should also wipe your battery stats once the phone is fully charged.
Try that and see if it works for you. I know that I was getting great battery life even on the stock battery. I play "Word With friends" (at least 15 matches running) a lot (at least 15 matches running concurrently) and this game actually drains battery. I still got through the day fine though I also carry a Touch Pro 2 and having the batteries that are the same size allows me to swap when needed.
I have the 2650mah one from sprint and my 3500mah seidio coming in the mail tomorrow. I'll probably write a review for it later. Note, On my 2650mah, it's already on its 12th hour and I was was playing WWF, surfing the web, made several calls and it's still at 77%. I will leave it off the charger tonight and see how it fairs tomorrow.
Good Luck!

I have tested these and if they do last longer then stock, it is only like maybe 20 mins. I have an external charger as well as running the SBC kernel to get a complete charge. I have the sprint 2600 battery as well and love it. Not many cases for it but I have modified a sedio rugged and ballistic to work with it. I let my wife use it for a few days in her evo and had to fight to get it back from her.

[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.

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.

...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.

[Q] Does this mean my S3 needs a new battery?

Ever since last week, my battery has been misrepresenting the % of battery. For example, last week, I had fully charged my phone in the morning and it said 100%. Right after I pulled out the charger, it said it was at 60% battery. When I used my phone, it dropped 1-2% every minute. I thought it was an app or something that was doing this, so I installed Battery Doctor. It didn't really make a difference.
I'm posting this, because right now it's worse than ever. It said that I had 100% battery and then right after I pulled out the charger, it said it was at 56% battery. After I closed the screen, it said 100% battery again. Then it started to drop %'s every few seconds.
Some information that might be handy:
- I've had the S3 for 1 1/2 years now
- Was rooted, after update, root was removed and I haven't bothered
-Attached to the pictures are two pictures of my battery today. I haven't done anything but screenshot twice.
Also if it is a battery problem, what type of battery should I get? I'm thinking of buying an Anker 4400 mAh Extended battery (http://www.amazon.ca/Extended-GT-I9300-T-Mobile-Cellular-EB-L1G6LLU/dp/B009GVG8FA).

Chances are that your battery is dying. I don't really know which one is best to get as replacement though.
You should also take a look at what is using your battery, there might be more than a dying battery (app, system). Can also get OS Monitor to see if something is over-using your ram/cpu.
N.B.: Extended battery makes your back cover much larger, you'll also need a different case (if you're using one).

Nothing's using up my battery because I checked through a multitude of apps and the processes running were all the same as before my battery was really dying. I do have a case so I guess I'll just try to find a smaller battery. Thanks for confirming my suspicion about my battery!

I have the ZeroLemon battery. 2300 ma. Same size as stock battery. It was a good deal. They give you 2 batteries and wall charger. Only downside is it does not have NFC. I don't use it so didn't bother me.
Sent from my SM-T310 using Tapatalk

I got the zero lemon 2300 and I went from 1.5 hrs of screen on time to a little over 4 hrs of screen on time. Once while doing nothing but watching videos I got 5.5 hrs. My phone is the same age as yours. Seems that is about the lifespan of smart phone batteries.
edited to add that my phone would lose 2.5 % an hr while idle, but now it's only 0.4%.

Phone abruptly dies under 20% battery

Phone totally goes black/dies when battery is 21% down to 10%. does this just mean the battery I have is bad? What replacement battery is best? I've read Anker makes a good set with charger. Thanks.

Samsung SDI batteries are the only batteries I've known to do this. When screen goes black, that should be a shutdown. Do you plug in your charger at that time? Mine actually actually showed 0%.
It's inconvenient for a battery to shutdown unexpectedly, while showing capacity remaining. I always replace Samsung OEM batteries with another brand. I found one that I liked so l went to Amazon and bought a second plus external charger from same brand. If looking at another alternative, just search MPJ and read the reviews. The battery and wall charger were on sale last week, maybe still.
If you're considering upgrading to sealed battery in unibody phone, you should consider the care required for such a phone to get battery to last. Sealed batteries are actually very similar in capability and ratings; no leap in tech but apparent shortcoming evident in Note7 embarrassment. Fast charging produces heat and steals life from battery's endurance down the road. Studies have shown since lithium batteries have no memory that you're actually prolonging the battery by slow charging without load or minimum load and bump charging rather than cycling battery to near 0% then back to 100%. Manufacturers don't tell you that because they prefer you wear your battery down in less than a year's time and consider another phone purchase.
Maybe Samsung would be better off today if consumers were more aware of how to prolong lithium batteries?
If you want your battery to last two years, bump charge it after 25% used as much as possible; it shouldn't even matter if you bump charge it 3x per day. Avoid fast charging and heat cycles. IOW, try not to use it while charging; the cycles should be short anyway.
Or, if you prefer to abuse a removable battery like the Note 4 and care less, pay about $15 and just replace the battery every year. 500 full cycles is all these batteries are currently rated for due to increased degradation with abuse. Mini cycles allows more of those cycles without degradation but you'll still have capacity when you need it to last a long day without charging.

Try this, if you are rooted and have recovery wipe dalvik cache and cache. Power off phone and pull battery for like 5-10min. Hold the power button (with battery out) for like 1-2min. After letting battery sit out for 5-10min reboot and see what happens. If same instances occur. Your battery is dead just purchase a new one! Anker recommended!

You're welcome.
Bump charging is partially charging before battery gets low. An example would be running the battery down 25% and charging without overcharging it.

Had the same issue, bought a new Anker and issues resolved, the stock Samsung sucks!

I'm just glad there's a way to replace it that'll mean this phone can last a long time if I'm careful with it.

Yeah it must be these batteries. My mom has the Note 4 as well and hers does the same thing. As does mine

Yes the stock Samsung batteries are horrible. They don't last very long then they start misrepresenting the battery statistics to the OS so you get the shutdowns at 20 or so %. I switched to a twenty$ Anker I found on Amazon over 6 months ago and never had the issue occur again. Even thy sprint techs will tell you if you ask them outright!
