Defective battery from Samsung - Epic 4G Q&A, Help & Troubleshooting

Hi,
I've had my Epic for a few months now and it appears the battery has started to go bad, it cuts off charging at 4.1v or 4.08v. I took it to a sprint repair center and the rep said that it was operating at only 90% capacity, so he said he reset its internal chip to 100%. Now, a few weeks later, it's back to doing it again. Samsung's website says that the battery is not defective and eligible for warranty replacement until its at 80% capacity.
Does anyone know what voltage 80% is? I'm having trouble calculating it and I don't want to be wrong.
Thank you!

Samsung Captivate for AT&T
When I first received my Captivate they accidentally had the wrong volt battery in my phone - WTF?....Samsung/ ATT support quickly sent a brand new replacement...make sure battery replacements are not refurbished and are in fact new. Sealed in package.

hmmmmmmmmm The amount of hassle to mess with the carrier or Samsung over just getting a new battery for 12 bucks, doesn't seem worth it to me....
I would just buy a new battery
BTW you can go into recovery and reset the battery stats yourself go into recovery>then advanced> then reset battery stats.
Also there a some apps that allow the battery to drain further down lowering the low set voltage down appox, .2 volts

[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.
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.

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!

New battery won't charge past 84%

Okay so the other day I bought a brand new battery for my tab s. The old one had been overheating. And I went to charge it, but the charging stops at 84 percent and refuses to go any further.
It's not the cable that's fine. No particles in the port. I've tried wiping the cache, and a few other ways.
But nothing I do works. Does anyone know why my tab won't charge past 84%? Is there some way to fix this that I haven't tried?
Oh and please don't tell me the battery may be bad, it took so long for it to arrive because of delays. I can't sit through that again if it turns out to be bad.
How did you fit the new battery? I presume you had it done through a service centre as the Tab S battery is an internal battery!
Sent from my SM-N9500 using Tapatalk
No, I did it myself. It's pretty easy actually.
I don't like bringing my tab to a repair shop as not only do they make you leave it there for days and charge way to much. But I did so with my last tablet and I don't know what they did, but a week later it stopped working all together.
A fully charged battery is approx 4.35v you can download a battery app and it will show you the voltage, So 100% should equal approx 4.35v
Try re-calibrating the battery check the guide and the link to app below.

I replaced my battery back in May that I purchased off ebay. The battery is dated 2017. My battery charges 100%. Maybe you got a older battery that was on the shelf too long, or is just defective. Also I received my battery in like 3 days. I would try buying another one from a different seller because there are good batteries out there. Ask the seller what is the manufactured date.

HTC 10 - Replacement Battery - Have you done it?

Does anyone have any direct experience (not hearsay) or a link to anyone who has actually done actual testing on any replacement batteries.
Ideally, something like what Richard Lloyd has done on youtube to test 18650 batteries.
*** As we can use the google machine, please refrain from links saying "this battery sucks" or "this is the best ever!". Reviews on amazon, ebay, aliexpress and others can be bought for pennies.
It would be great to see someone doing math and using electrical measurements, not what an app reports. ***
----------------------------------
So, two-ish years later and my unlocked HTC 10's battery is starting to go.
I'm using the latest build of Leedroid's rom and no, it is not the rom.
I have replaced batteries in the past and feel like I should give it a shot even though HTC made it a b*tch to change.
Why I'm asking: I changed the battery on a past phone and it worked pretty well for 6-ish months. Then, it exploded and cracked the lcd and g glass screen.
So, trying to avoid that.
-----------------------------------------------
Facts (as I understand them):
We cannot get a real / genuine HTC 10 battery.
HTC does not sell them.
Anything labeled as such is most likely a Chinese fraud or an actual HTC 10 battery that failed their internal inspection process.
-----------------------------------------------
Does anyone have any experience with the replacement batteries that are for sale on Aliexpress?
Part number: B2PS6100
Brands (stickers?):
Cameron Sino 3000mAh
HSABAT 4300mAh
Ciszean 3000mAh
LOSONCOER 4300mAh
XINBONG 4000mAh
Dxqioo 3000mah
etc....
What buyer did you get your best / working battery from? Details please!
Has anyone ever gotten a reading of more than 3000mah that lasts?
I've read on oneplus forums that many replacement batteries often only provide ~80% of the real battery when new and fully charged (mAh).
Many have concluded that batteries that fail their inspection process are not properly recycled and are being re-branded and sold under new names / stickers.
Comments welcome, hopefully my caveats at the beginning didn't scare off everyone.
Thanks in advance!
Mine is also 18 months old and looking for some alternatives . Hope somebody gonna help us.
I've done mine got it from repairbase.co.uk but haven't done any tests on it other than what an app called acubattery which estimates it's capacity as 2868. I've never fully charged it got it set to only go to 75% in the hope that it'll last longer than the original.
Ref the actual swap it wasn't that bad,
I heated the screen on a microwaved wheat bag
used some suction cup pliers to lift the screen
Cut the glue with a guitar pick
Made a simple diagram on a bit of cardboard to stick the screws in.
I took all the tape off completely stored on a bit of greaseproof paper and was really careful with the screen ribbon.
I replaced my own battery.
I replaced my own battery. I bought it off of ebay from a seller in the US. My phone used to have random boot loops now that no longer happens.
It was difficult. Heating the display and pulling off is a problem. I actually broke my display and severed my ribbon cable for the sim. I replaced those parts and battery change was successful. Now the only issue is the adhesive is not sticking that great. Nothing that affects anything. I just see how the screen slightly gives just a little bit. I do not recommend the double stick tape. Get the special glue!!! Something with a 7000 in the name.
I will be reheating a gluing it in the future. I dread working on this phone. Although I am not a professional I think I did a pretty good job. Other phones are much easier to repair.
I DID NOT notice a super improvement in battery life. My new battery was now back to "Ok" battery life instead of terrible no more bootloops at 20% or when camera is open. There is a problem with the HTC 10 with the cpu using to much, along with wakelocks and wifi. I really wish HTC would address these issues.
I installed LEEDROID have not switched kernal yet. I have getting over 4hours and 30 minutes of on screen time. If I change the kernel and throttle the cpu I may be able to get a little more. The goal is 5 hours.
I am NOT an EXPERT. I am a smart individual through trial and error that can figure many things out. I like to get the most out of my technology I'm not ready to get a new phone. My phone is primarily used for Audiobooks, Youtube, web browsing, texting.
i wanted to replace my battery... but after watching this video i've lost all my motivation ^^
as soon as my battery starts to crash at low percentage i'll take another look at it ^^

Oh.... and i always tought these batteries are from the same manufacturer as the original one but somehow stolen/bought directly at the manufacturing site and sold by private persons.
It is really hard to distinguish a real battery from a fake...
But to know if your battery is full/new or not the only way is an external discharge test.
I've tought about buying one of these https://www.ebay.ch/itm/ZB2L3-Batte...560532?hash=item25e6002a94:g:ag4AAOSwmnFZ4hxs
But it says 3A ... which is a bit much for this poor phone battery.
Having a functioning temperature sensor is critical to the stability and safety of the battery. If you've replaced your battery, use an app like Accubattery to verify the following: an existing thermistor will read a fluctuation in temps anywhere from 20-50C based on usage and ambient heat. Most (all?) of the batteries sold online have only a resistor which will send various inaccurate readings to the phone, typically 25C while charging, and a jump to 35-38C while unplugged (if the plugging/unplugging makes no sudden difference, try putting your phone in the freezer, or going between idle and heavy use to test).
If your replacement battery has an accurate temp sensor, please add to the discussion by telling us where you purchased it.
i bought HSABAT 4300mAh from aliexpress,i replaced the battery .will share with you guys here the results
Shame it's so much effort to change battery my wifes phone always turns off at around 21% now and she doesn't like any of the newer phones most are too big this htc 10 was the max she would go to.
My guess is that a lot of people are going to try in the coming 2-6 months as their battery starts to weaken.
Phone is great. Processor is fast enough and camera is great.
My hope is that we can gather real info and start to get good intel on these battery brands (?).
I don't think changing the battery is particularly easy, but it can be done. (See YouTube)
That being said, I don't want to have to do it more than once.
I hope more people chime in, because I guess many have already and many more will be doing it.

Hey @alicine. I'm really curious about the battery and want to buy it. I have some questions and would really appreciate if you could answer them.
1) Has it exploded yet?
2) Is it the advertised 4300 mAh capasity?
3) How did you make it fit inside the shell? Is it the same dimensions as the 3000 mAh ones?
4) How long does it take to charge & does it still support fast charging?
5) How many hours of SoT are you getting now? (which ROM you're in that would help too)
Thanks in advance.
Tips from experience on M7
One thing about lithion batteries . . . they lose a bit of capacity just sitting on the shelf as matter of simple, natural deterioration. So to a certain extent, the newer the better.
When I replaced the battery on my HTC One M7 it was a similar challenge. My approach to buying a battery was to look closely at the photos and see what the date was on the battery for sale as it should be printed on it. (Some of the sellers don't even know that.) I tried to get the most plausibly recently made battery, within reason. By that I mean, I was concerned that for an older phone there might not be any batteries recently manufactured for it, so a very recently dated battery might be fraudulently remarked/re-dated. If I wasn't sure I queried the seller to find out if they knew what the battery's date was.
I'm not sure my theory is correct about which date battery to shoot for, but I'm still going with that line of thinking
Hi, what about the battery performance with daily use?
@numpaque
I'm not sure what the question is there - batteries lose charge as you use them, then need recharging.
What do you want to know again ?

1-No its not exploded yet, its working very well
2-I guess no , because im having same SoT as i get it when i first buy the phone
3-I removed the screen first,then one by one other compenents.Dimensions are the same
4-Its takin 50-60 mins to charge from %5 to full
6-Stock rom 4-4.5 hours depend on the use
I sent my HTC-10 in for battery replacement through the official service in Germany. This was approx. 6 weeks before my warranty ran out.
Battery performance was really bad with SOT of around 2 hrs, and random shut downs at 20-40% battery capacity.
After 2-3 weeks it came back, and according the delivery paper the battery has been replaced.
But regrettably no improvement could be notified.
So I sent it back again and got it back within approx. 1 week. This time they had replaced the side keys on the Phone, but even this time I could not find any improvement of the battery performance.
So I claimed it a third time, and sent it to the official service again. But now my 24 months warranty was gone….However they still accepted this as a Warranty claim and when I got my phone back after approx. 2-3 weeks it had a new battery, and a new screen.
Since then, the battery performance is good and my phone works more or less like a new one.
I get SOT between 4-5 hrs and no more shut downs and boot loops using stock Oreo.

frined buy it from the same shop 1 week after me and he still got 4h+ sot.so i guess some devices sold with deflected battery?

Got a battery replacement to extend my phone's life but I see almost no difference.

I have a OnePlus 3 which I bought in June 2016. Fair to say the battery was starting to deteriorate. I had always planned on keeping this phone for at least 4 years. So to extend its battery life, I went ahead and got the battery replaced at the authorized OnePlus Service Center (for $25).
I see almost no difference though. Also, the battery capacity comes up less than 3000 mAh in the advanced battery options in my phone's ROM (2688 mAh). My older battery showed up as 2250 mAh.
I checked up on battery calibration but seems like it is not required at all.
Is it possible the OEM's provide poor replacement batteries so people aren't able to extend their phone's life which is otherwise in great condition? Or is the advances battery info erroneous?
They gave me a one month warranty. Would anyone recommend that I go back to them and ask for a replacement?
If it helps, I am on the latest HavocOS build and have root enabled.
I sent my phone directly to OnePlus 1 month ago, but I did not notice any improvements, I'm not sure they actually changed the battery even if they say so... Also cause I had a dbrand skin on and they haven't removed it.

Have you calibrated the battery? It is advised to with a new battery. Normally 2x Discharge to 10% then full charge

They actually gave back my original battery. And the number of charge cycles can be found using a bunch of apps. Not sure if that can be reset. So you can try using one of those to see if your battery really is new.

May be the 'new' battery was manufactured in 2016. Remember that the production of OP3 was stopped after the launch of the 3T. So this battery might have been sitting on the shelf all this time.

to confirm your capacity Check your battery in AIDA64 from play store.

Wow thanks for that info. Btw I switched back to OxygenOS (One3OS) and the battery life has drastically improved for me.
