[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.
You can find the URL here:

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.

HTC battery trick for HD7 and possible others

while on charger when the battery is reaching 97% , turn on/off/ the phone
multiple times , each time taking a 2 mins break u will notice the charging takes longer and the percentage is always stuck at 97% - 99%...
another form of bump charging for wp7..basically the phone will take longer to cut off charging at 100%
post yr results here if u saw improved battery life

you will find this quickly damages the long term battery life of your battery

Well that isn't so bad as batteries aren't expensive anymore. Just 12€ or so.

this would probably work for any phone not just HTC but you are basically tricking the phone into over charging the battery which weakens the lifespan of the battery, all for a few extra minutes of battery life, not worth it.

Yea, this is terrible, destructive, downright negligent advice.

Yes, not good. I work with battery chargers and Li battery characteristics and you will actually age and get less capability very shorty doing this so you won't get those extra charge lengths for long (you do this maybe 20 times and you will in worse shape after that than someone just doing normal charge).

Hah, this coming from the guy that advocated doing that.

u understand yr cause of concern....this will not wear out the battery faster...unless batteries that u use do not have rapid discharge capabilities eg. Iphone poly battery.
In this case it will wear out the battery faster
basically the battery wears out the same rate as all other batteries...
the cells degradation occurs each time u charge...
and modern batteries do not overcharge...some like HTC batteries will discharge rapidly to 80%
basically u are just charging the remainder of the cells

Quote me where I advocated doing that.
Please do a post search on me and you'll see that we've had this discussion in the Vibrant forums already, where I stated it was dangrous.
What I do advocate is keeping your phone on a charger whenever possible (bump charging).
I do not advocate tricking the phone into overcharging. No one wants a battery to blow up in their face, you know...
Or maybe you're confusing a confirmation of that working with an advocation that it's okay to do it? In that case, your school district obviously failed. It has nothing to do with what I stated on these forums or otherwise.

The issue doesn't come from fear of wearing the battery down. It comes from fear of a device blowing up or catching fire on someone who is overcharging it. There is enough evidence even on youtube of batteries going haywire. This is a risky tactic to achieve basically no noticeable increase in battery life.
The HD7 in a high 3G coverage are (full bars, 3+ Mbps download speeds) gets ~4 hours of battery life under heavy use (mostly browsing, reading Pulse Reader Articles, and checking Social Networks now and then - no Music or video - so really it's only heavy in the fact that the phone didn't sleep a lot, should be called more moderate if anything... Phone shows 67% battery left with 2 hours projected uptime). Overcharging your battery won't change that terrible battery life into good battery life. It'll only make it 5 minutes less terrible.

they can only blow up by removing their circuit protection

If you say so
Batteries still overheat, catch fire, and in rare cases blow up. Overcharging them is risky. Yes, it's rare, but would you want to be that 1 in 10,000 case where it does do that, in your pocket or something?

1.) This will wear out battery faster, why? You are fooling the sensor to charge the battery more.
2.) You can overcharge batteries, don´t know where you found out you can´t. The only good thing is, that the modern phones cut out charing when battery is full and is running on charger (to keed battery charged).
3.) My battery is not rapidly discharged to 80%, I charge it up 100%, and it stays there, when your battery quickly discharges to 80%, that´s your problem from experimenting with charging.
Again - STOP TELLING PEOPLE TO KILL THEIR BATTERIES, I told you numerous times, you always act like you invented something, you didn´t, modern batteries use more advanced techniques to help them prevent from being damaged, overcharged, deeply discharged, etc. So stop telling people how to fool these sensor and stress the battery.
Thank you

Hey guys,
I wouldn't recommend this advice as well.
As for me, I bought a second battery 1600mAh.
I use this battery as my primary battery, now I get 30-40% more time on my HTC HD7, and actually can go a whole day with 2G only. While before the phone dies before the end of the day.
While my original battery I keep fully charged sleeping in my wallet, so if the 1600mAh is fully depleted and I'm away from a charging station, I quickly replace and resume working on my phone. This method gets me through a whole day of work+games+social.
I don't remember the price of the 1600 battery but it costed me 10-15 Euros I think.
I believe this is most practical than carrying an attached battery to your phone which results in a gigantic phone in your hands. Or overcharging the OEM battery and probability of having it blow up.
What do you think guys?

New to wireless charging

Hey people,
New to wireless charging here, my girlfriend just bought a wireless charger for my birthday. Just one question, when you are charging and you need to use the phone, should I pick it up or leave it there and try to use? I mean, if I keep picking it up to use, wouldn't the constant charging/stopping damage the battery? Please help me out!
Thank you!

No, it's fine. Pick it up as many times as you want. I have different wireless pads scattered throughout my house, office and car, that it will not "hurt" it.

It's probably fine. But if by constant you mean literally every 5 seconds then maybe not.
Also there's a xposed mod to disable the sound every time you put it on the pad if they annoy you too constantly.
BTW it'd be great if I had a techy girlfriend

thanks for the comments guys

AFAIK li-ion batteries does not suffer from any memory effect and they even last longer when kept charged. Battery charge cycles are still there as an indicator of the goodness of the battery from the manufacturer but they are related to a full cycle (eg how much current passes through the battery) but smaller charging cycles shouldn't be counted as full.

Just use the pads no need to "worry" about the battery. In some instances batteries will need replacement, but many replace their devices well before you see an issue.
I don't want to go to e-war about batteries. I am just going by personal experience. I have my N4 still, which my wife uses and still uses charging pad still no issues there either.

Could you provide some references for our edification? I admit I'm not the most knowledgeable on the subject but my understanding is that charge cycling is bad at or near full charge. I don't know that this a problem at lower charge levels (let's say <90%).

I don't have an EE degree but from what I understand newer batteries cycles are a full charge from 0-100. I read something on apples' website explaining this. So charging it twice from 50-100 would be one cycle.

You might be right about the charge cycles, as most things seem to relate to amount of power transferred through the battery, and not 'depth of discharge" but honestly many people I've met who plug their phones in all the time to top up, end up having to get the battery replaced after a year. Apple product, ok no problem they do it free for like 2 years; but I've done nothing but run my batteries all the way down every time and slowcharge every night on USB-500mA (gentler current, kinder to battery, cooler temps, and even a slightly more thorough charge) (just 5% POSSIBLY 10% it's hard to say...probably 5%...I guess I should test this)

EE to charge? No, I'm just saying you might want to think twice before picking up 20 times a day from the pad. Better to get MightyText for when you're at your PC/work to text with.
the google charging pad IS better I would have less issues charging on one of those. However, I'm a cheapie, and use $10 chargers, which heat my phone usually to 40C for a full 0%-100% charge. Not best, but I have resigned myself to the reality of potentially replacing the battery in 18 months if I want the convenience of charging pads everywhere. You might wish to think this way as well. Also, after 18 months, maybe you could just charge it at every opportunity (at that point, who cares, you only need it for another 18 months probably) and that would be enough.

All I know is since 1998 I charge my phones to 100% as often as I can find a charging device. I am the only one on my family plan of 5(the others run battery down daily to~30% or more) that doesn't replace their battery before their next upgrade. So my motto is *Top up every chance you get*.

Also, after 18 months, maybe you could just charge it at every opportunity (at that point, who cares, you only need it for another 18 months probably) and that would be enough.

Not sure if it makes a difference but nexus 5 uses newer li-po batteries not li-ion.

Worried about unremovable battery

This will be my first phone with a battery I cant replace. Batteries lose a lot of capacity and will be down to something like 75% after 12-14 months. Has anyone got a battery replaced on previous models? How much did it cost? What is the battery capacity loss like in general on HTC phones? Thanks

The battery on my m9 has kept itself together well considering it's a year old. I have flashed the sense 8 launcher and now the battery is as good as when I first got it. I wouldn't be worried bout that mate

I haven't had a removable battery since the a Nexus 5. My Nexus 5 turned into a media player and it holds a charge for about 3 days easy. 5 days when I rarely touch it. It's almost going on 3 years old. I don't miss a removable battery all that much as I thought I would.

You also have QC 3.0 and the HTC charger has some cooling tech, so the battery should have a better lifespan than previous iterations anyway.

the point of having replacing battery is to carry one with you at all times to replace it, right?
I think, if you're gonna carry something i would rather have a power bank, less dangerous to have around and takes way more battery and you don't have to remove the battery to use, yes it has to be connect to the phone, but hey, everything has pros and cons.
I prefer the power bank and i also never had to change a battery because it lost quality, but that's me

No, I replace my battery every 6 months as batteries lose capacity, after replacing it, I always get a big increase in battery life, after 1-2 years, it may only holding 60-70% of original charge

have you tried calibrating your battery before replacing it with a new one?

You must be doing a lot of charge and discharge cycles a day to wear it out that quick...

So I've had my M7 since I pre-ordered it April of 2013. Still the original battery. If I unplug the phone at 8am and use it normally throughout the day (occasionally browsing reddit/YouTube, texts/messenger/emails during downtime), it probably lasts 8 ish hours without charging it at all.
Not sure if that helps. Can definitely tell it's degraded a bit since I first got it.

Your phone doesn't get to 100% in 5 seconds with a power bank, a replaceable battery does. A replaceable battery is a lot lighter and smaller than a power bank. And who wants to use a phone with something tethered to it?

if you're using the phone you're most likely not moving a lot either, which means you can easy stay still and connected to the power bank, there are small power banks and some even give you quick charge option, but like i said or meant to say, use whatever you want and think it's better for you

My M8 was purchased on day one and after two years of use it's still going very strong. I don't notice any significant differences from my initial impressions.

How do you calibrate battery?

M7 three years old. Always get 4 hours plus sot. Even got seven when reading heavy. I wouldn't worry, just don't charge all night, buy a timer.

Attached the wrong one, even though it was good too.

Batteries are odd things, especially Li-polymer batteries.
Like above, my M7 is 3 years old.
I get 14-20 hours average out of my phone with a LOT of web/email and poor coverage (mentioned because it sucks more juice in thinner coverage). Currently I'm on 13+ hours and have 17% left.
The real damage to these batteries is # of charging cycles and heat. Heat prematurely wears out the chemicals and each time you plug into charge you're killing one of a limited amount of charge cycles.
You should not see a true decrease in capacity as these don't have memory effect.
I'm a horrible user in that I often plug into charge when in the car and tend to run my battery way down before recharging, both of which are hard on a battery.

When you get a new phone there is not need to worry about this at the beginning, but after 2-3 months you should think about doing a full discharge, from 100% until it turns off, even after it turns off i don't plug it right in, i try to boot it 2 or 3 times and let it turn off by it self again, then just charge it 100% again, this should help is some cases (do this procedure only once a month maybe, there is no need to do it all the time because it will put strain in the battery and if you do it a lot you will also lose battery life).
Another thing to keep in mind is that tests have shown that if you can, you should charge your phone at +-50% (instead of 20% or less) until 90-98%~, of course not everyone has the time for this but it's something that helps maintain battery life.
Battery's also need exercise and keeping the battery plugged in a lot won't help, if you can avoiding stressing the battery with high temperatures as this also reduces the battery life.
There might be a few more tips for battery's but this is all I remember/know for now, hope it helps :good:

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.

Wow thanks for all the information. What does bump charge mean exactly? Now my battery won't charge passed 90% either. A different one is on the way.

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!
