Another MT4GS battery thread

So today I was charging my phone after a little over 7 hours use and it simply jumped to 99% from 24%.

I just calibrated my battery like a week or so ago so I'm beginning to think that my battery(stock) is broken. Just ordered an Anker to replace it.
Could this be caused by charging from different chargers/sources(like standard htc charger then via usb and or another device's charger)?
Does the battery usage section report the battery usage acurately? Because I think mine doesn't, whether or not my device stays with screen of for a fair time of the time between charges/brightness at zero it still reports screen using the most power
Edit: On PyroICs 1.1.0

You can absolutely damage the battery by using blackberry chargeres, or ones that deviate too far from 5v-1a.

Not charged my phone with a blackberry charger. Just a Samsung galaxy mini's charger and a Huawei IDEOS charger. The only other power source I've used is USB power from my laptop when I'm on the go.

The OEM battery is known to have terrible life. You're better off with either a Mugen or the Anker two-pack.

I have both the 3600mAh Mugen and the 1800mAh Anker two-pack. Both are great. I recommend the Mugen if you can afford it.

Aye that's something to watch out for. Maybe go with the Anker and if your still not satisfied, look into a Muugen 18 or 36

No blue, I'm going to have to call you on this one. No damage that I can see. Been charging my old G2 with a BB charger for at least the past 4 months. No problems at all.

you'll see it sooner or later, you are wearing out the cells inside it - they weren't made to take that kind of stress.
When i'm not getting ready for work i'll dig up some info on why specifically.

Blue i would say your wrong aswell i used a BB charger form my old Mytouch 4g for about 11 months and my battery still functioned properly as was lasting its standered period of time like always.

What's unique about the BB charger anyway?
I noticed some time back on a previous device I had(ZTE Blade) it would disable the touch digitiser as soon as you plugged it in, though it would still charge the device.
Is it something to do with the way its earthed?

...and I think someone else posted in this thread about using a BB charger and it being fine over time.
I don't care about being wrong on a personal level, no ego or anything like that - i'd rather be corrected if i'm wrong so I don't spread misinformation. So far that's at least two people (quoted from this page, didn't dig further back into the thread - cumbersome to do on the device over lunch through the browser)
So that's some people providing information based on their direct observations, it's up to me or anyone else who has supporting info to provide it to show why trickle-charging at low amperage is bad for the cells in the battery.
Just 'cause it works and you get away with it without the appearance of issues doesn't mean it's good for it or not doing damage.
I once drove my Bronco a little over 300 miles round-trip to camping in the mountains at a remote site. It was carrying all of our gear and the people were riding in other vehicles, and the Bronco was overloaded (by a lot). I only had 2 cylinders out of 8 working, the sparks were shot in the other 6. 3 were down before the trip started, didn't have a chance to change them, and at one point early in the drive I came to a quick stop on the highway from fast to nothing and flooded the engine, causing 3 more spark plugs to stop working (shoulda seen them when I changed them after I got back - 2 were outright broken lol)
The Bronco still pulled it's weight and got us there, was able to keep up and was 4-wheeling off road and lots of fun. Obviously not good for the engine, tranny etc... but it did it, and without any issues.
I've got just over 1600 logged rounds through my Glock since the last time I cleaned it (intentionally - glock is supposed to be reliable and it's a torture test i'm putting it through to see how many rounds between cleaning before a misfire)
Obviously in both cases the manufacturers don't recommend doing what i'm doing. It should be pretty plain the objects spoke about were/are being abused. Yet they function/functioned just as well as if they were being cared for properly.
The abuse of the cells in the batteries is no different then the two situations I described above. They are not designed to be charged at that trickle rate, and doing so stressed the individual cells in the batteries.
I don't have links to cite technical specifics, and i'll have to go out of my way to track down the information to put here to explain why on the technical level. I don't know how soon that may be, but it's important for us to lay this to rest one way or another.
I'd love nothing more then for the information i've put together about lithium-ion batteries over the course of my electronics education to be proved wrong due to new developments in battery technology/tolerances and that you can in fact use something like a BB charger to charge them, but it flies in the face of all I know about proper care of the cells in the batteries themselves so...

Blue is an interesting character, I must say lol...
Either way, I'll take your word for it. You probably know better than me regardless. I was just saying I saw no apparent damage. But then again this damage doesn't need to be apparent.

always nice to get what you love!
seems as if the important thing is not input current, but ensuring that the battery is not 'overcharged'.
Charge currents with Li-ion are less critical and can vary widely. Any charge will do, including energy from a renewable resource such as a solar panel or wind turbine. Charge absorption is very high and with a low and intermittent charge, charging simply takes a little longer without negatively affecting the battery. The absence of trickle charge further helps simplify the charger.

Blue is awesome! The stories are greatness.
I also have used my bb charger on my g2 and this phone with no problems. I did eventually have a probelm charger the g2 but it was something wrong where the charfger was actually connecting. You would have to hold the phone a seperate way.. had another g2 that was fine before that one though, until I fell on it. 280 pounds > g2

Super OT I know but,
Check out Chuck Taylor's super high round count Glock 17. A million or so rounds through it. Insane. I used to have a Glock Armorer's certification back when I was the Police. Glocks are extremely durable and reliable pistols. The caveat I'll pass on is shoot no unjacketed lead, only jacketed bullets. Too many rounds with Pb and no cleaning can have you eating bits of your chamber... It is hard to write kernel code without the use of your fingers and eyes.

S3 2300mAh Battery

I just wanted to share the deal I found on a spare battery with 200 extra mAh. I would imagine that this does not have the NFC chip, but I wasn't too concerned with that as of yet since I don't use any tags yet anyway. I spent a little over $3.00 with shipping for one battery. I figured even if it was garbage, I'm not out much money.
http://www.ahappydeal.com/product-86003.html
Update:
Received this battery today. It was at 68% when I put it in this morning. So far, so good. I haven't noticed anything out of the ordinary, like excessive heat.

is it safe to use I9300 battery on our device?

Even the real one that costs $44 does not have great reviews. Will also lose NFC capability that the $44 one has. Should be ok for backup if does not explode in phone.

Fishy.... very fishy... also curious to see how this pans out.

"$3.00 with shipping for one battery" = guaranteed junk

I was given one of these exact looking batteries (can't be sure of brand/manufacturer as they're un-branded but they certainly have the same sticker from the looks of the picture) and thought "what the hell... it's free" and started using it. Less than 3 days in and I noticed my phone getting warmer than usual. Didn't think anything of it, thought it might have been just from me using the phone more. About 5 days into using it the phone started getting REALLY hot when charging. Next thing I knew, while charging the phone, the edge of the battery cover "popped" and was pushed out so it unlatched from the phone. You guessed it, the battery was swollen and HOT to the touch. Hot enough where I couldn't hold it bare handed for very long. Unplugged it immediately, placed it in a heat/fire proof container to let it cool down, but it kept swelling for the next 5 mins to the point where it won't fit in the phone any longer. (Not that I tried, but from the looks of the deformation there is no way it would fit in the battery compartment.)
As they say, you get what you pay for. Why risk saving ~$30 when it can damage/ruin your ~$500 phone! Worst yet, why risk it for bodily harm to yourself or your loved ones?!! (Perhaps this can be a covert way to dispose of/harm your mortal enemies and blame it on faulty junk electronics... hmm...) I'm fairly certain that if I had kept charging the battery there would have been a very likely case of it starting a fire as it was on top of a paper book on my night stand while charging. I can't imagine how horrible I would feel if MY phone had started a fire that ended up hurting or killing someone in the process...
Moral of the story - yes, you might get a battery that works well for you and I'm sure many people have, but why risk it?? My suggestion - STAY AWAY! STAY FAR FAR AWAY!

I actually bought this
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=330768545772
supposedly 2900mah
comes with 3 batteries and a charger
Now my word of warning: I have used these china batteries before for my other smartphones. They never gave me an issue of overheating or anything like that, but dont believe the power ratings they have. it is NOT 2900mah. Its probably more like 1800mah
I keep them charged and use them in case my phone dies and I have to have a phone right away. I dont use them as my normal day to day battery.

I got two Anker batteries for $15.00. I usually only need to resort to using one of them each week, but I always have a second if needed. I believe for a few more dollars you can get an external battery charger. That takes care of the charging problem.

How about two batteries and a charger from hyperion for $20. I believe this to be a fairly reputable brand. It can be found on Amazon if you search for hyperion. Sorry, it appears I am not cool enough to post links yet.

Haven't tested the Anker 2200 yet so I cant say for sure which battery is the best.

I might be looking into picking one up but am leaning towards an external one.

Thanks for the heads up.
I realize that this battery most likely is not a good battery. For $3 it would certainly be a good emergency backup.
It hasn't been delivered yet, but I'll give an update once I'm able to try it.

I use a seidio charge vault that was invaluable when I was on a work trip and started experiencing frequent hot boots on a previously fairly stable rom. Between trying to troubleshoot that and flashing to a backup I went through my battery pretty quick. It is also my go to travel charger.

this is interesting... is the s3 battery rated at 3.8v too? also, did you really see that 16% improvement in battery life?

Battery life is better yes. And most cell phone batteries are 3.8 volts, and report as "full" at around 4.2 volts, although the app I use for battery monitoring shows the relay is charging my battery to 4.3 volts.

The stock battery life on our phone is pretty decent. But I wonder what kind of extended slim battery options we have for our phone specifially....
Great mod Nard. The S3 battery is very common and I think all aftermarket extended slim batteries for the S3 should work as well. As long as you don't have a problem ghetto rigging it, we can get a lot more juice for out phones. And it retains NFC. Massive plus

Holy cow, an extra 28% battery life for under $5? Heck yes! Just ordered this.
Edit: Don't see NFC mentioned anywhere... I don't use NFC, but just in case I decide I want to start, I'll pick up one of these, and solder the guy on if I need to. Looks to be about the right size.

I have one S3 battery, though from KINPS with 3250mAh that I got last time, which is 5mm thick (1mm more than ours) and should be allegedly same size to the S3 stock one.
But I am not able to close the back cover when I want to use it according to your instruction. that 1mm is definitely too thick and does not let me close it.
would you please confirm that yours is 5mm also or is it less than that?
if the prior, how did you manage to close the back cover?
if the latter, i would go buy a S3 stock battery.

If it's really that tight, I would try and carefully remove the sticker and see if it fits.
Compare it to the stock battery. Shouldn't be much thicker than that

I got a 3 pack of those batteries. All the three of them are just lying at home, their actual capacity was 2100mAh. Besides it didn't charge over 87%, which is 1800mAh approx. Don't know what the problem was, guessing it was the maximum voltage the battery could be pushed to using the phone. :/

Just let them sit overnight, they'll charge more

Actually the big possibility behind this is samsung has a battery overcharge feature...which is why your battery may only get that high...also Another cause might be to check and make sure your charger is outputting 5v 800ma as thats what is required by phone...i use stock charger with my 5000mah extended battery and loving it...gets full charge with both stock and extended battery....also to note...because of this overcharge feature depending on bad flash or similar it may actually brick your batteries (yes its possible). A prime example is i thought my old relay was bricked...when i got new relay i tried charging the battery from old phone and got the bootloop of death like i did on my old relay..so it got me thinking...and i placed battery from new relay and it booted right up as if a brick never happenned..i started to really research this and found ways to prevent this from ever happenning again as well as finding out about the samsung overcharge "issues" .

Besides when i used the battery, it lost charge out quite quickly and when i did a little research on the batteries, i found out given the size the batteries are likely to be fake and that the best batteries are the stock ones. The big extended batteries are however a different story altogether though. Anyway, i'd charge them overnight once and see if anything happens.
Here's hoping to the phone not bursting and burning my house down!!:fingers-crossed:

a good example...i went from 6 am to now 8:30 pm on my extended and its now at 75% batterry....i only paid 30 with tax and stuff total for my extended and happy i got it...again though...a lower voltage and ma charger will cause issues with battery drain and charge as well...like lets say you used a charger from another android device that calls for 4.5 or 5 volts but only 750ma or 500ma.... in terms it doesnt charge the phone properly causing more workload and time for battery to charge properly

I bought the extended battery of mugenpower (2300mah) for Samsung Galaxy S3. I scratched To insert the battery. The time now is charging but the cover does not close. probably also'll scratch the cover.
Soon I will insert photos of the operation.

Galaxy S4 batteries having issues like swelling and reduced charge holding capacity
It’s been only six months since the Galaxy S4 was launched, but it looks like many users are already having issues with the device’s battery. German site MobiFlip cites a trusted source working at an operator as saying that they are currently getting a lot of support requests for the battery. Apparently, as many 30 percent of Galaxy S4′s that were sold are experiencing issues with the battery, such as swelling and inability to hold a charge for long.
Batteries showing reduced performance is a normal occurrence, but that usually happens after a device has been used for more than a year or so. Thanks to the removable back plate, users can easily exchange the faulty battery for a new one, but they shouldn’t need to be doing this just six months after buying a brand new phone. The issue seems to be limited to only one country for now, so it’s possibly a case of poor quality assurance on a particular batch of batteries, but it’s something Samsung nonetheless needs to look into.
Any of you having the same issues with the battery on the Galaxy S4?

Samsung Galaxy S4 batteries are starting to kick the bucket, failure rate as high as 30%
Announced in March, and then put on the market in April, Samsung’s flagship smartphone, the Galaxy S4, has been out for a solid six months. According to the German publication MobiFlip, one of their “trusted sources” who works at an operator says that they’re experiencing a flood of support requests for the device’s battery. Apparently as many as 30% of Galaxy S4 units that were sold are either experiencing batteries that are dramatically losing their capacity to hold a charge, or even worse, the batteries are swelling.
There are two obvious statements to make here. First, Samsung couldn’t have predicted this with the type of testing they do since the problem seemed to only manifest itself after half a year. Second, if Samsung wants to prove themselves as being a company that cares, they should immediately put up a website where anyone, anywhere, can simply type in their address and have a battery sent to them free of charge. Yes, some people will abuse the system, but the good PR will outweigh the costs associated with pumping out a few extra batteries at the factory.
Is this embarrassing? Well, for now this appears to be a problem limited to one country, which makes me think that Samsung simply shipped a bad batch of batteries. This has happened to nearly every tech company, including Sony, Dell, and even Apple, though admittedly those defective batteries were in laptops, not smartphones.
Anyway, this will be fun to watch.

You're right, mine is also starting with BD

How do you check the batch

Seems that a lot of S4 are involved in that problem. Both Versions are hit, (I9500 and I9505) didn't know if the carrier models have the same battery.
Hopefully this is only a battery fault.
Here in Germany (9505) a lot of people have this issue.
30% I read also about.
Symptoms:
- Phone just powered off.
- Can't boot completely without charger connected.
- Battery level jumps
- Connection losts (consuming higher energy, faulty battery can't supply)
Call Samsung or Carrier to obtain replacement battery, in Germany Samsung Support is aware of this issue
Defected battery can catch fire while discharging, so cover contacts of the faulty battery with some kind of tape.
In Germany Samsung Support charge you to send back the defective battery, DHL (one of the biggest logistics here) did not allow sending defective lithium ion battery on the postal way. So I bring it to a big electronic discounter for a proper disposal.

Same here. Bd battery got swollen and started behaving as thread creators battery.

It is quite outrageous to release a phone with about 6 months of battery life.
I've read on some comments on the SamMobile post about the issue, that some countries refuse to change the battery claiming it is user-related damage.
I believe it will take a while until Samsung will officially and globally admit the problem before they will start replacing batteries for every costumer complaining about battery life or performance. Remember it took a while with the damaged eMMC chip on their former flagship.

I've the same problem in my battery, and yeah I checked it's S/N and found it starting with BD. My brother has the same phone but his battery is working fine and it's S/N starts with AA. So yes, I guess the problem is in the batteries which start with BD.

My battery S/N is also AA. Zero problems. It didn't swell and it performances great. I have the i9505 with stock 4.2.2 firmware (XXUDMHB). No root.

I had this problem about month and a half ago. Suddenly battery went flat. Would not boot up unless plugged into a charger, wouldn't charge, kept rebooting and shutting off when using simple things like YouTube. Sent it in for repair but o2 didn't state what was repaired. Anyways perhaps they put in a new battery but no issues since. Using the Anker battery and that's been great for me.

Omg, that's horrible.. for one moment I thought my screen might get curved too but I told myself "NO WAY", now I see yours curved :s
Did you let the swollen battery inside your phone for a long time?

Exactly as described - phone shuts down around 30%, cannot be turned on back without charger plugged in, front screen is slightly bent (pushed up) by swollen battery. So far, when I'll remove the battery, it returns to the original shape, but... but I wrote to Samsung - let's see if they will send me the replacement battery before I'll claim the screen damage caused by faulty equipment.
for any SAMSUNG manager/employee:
It is common term that your most recent phone (SGS3, now SGS4) is called flagship. Having in mind common issues like emmc, motherboard, battery, I have a tiny suggestion for you: Maybe, the Samsung company would promote use of the word: TITANIC, instead of FLAGSHIP? sounds far more appropriate, considering the quality of your last products.
30% of the faulty batteries? Really?

That's exactly what happened to my screen, when I removed the swollen battery it became normal again, but I dunno if it's 100% normal and no internal damage. So, I just wanna be sure that everything is normal inside and the screen is back flat again, because if the screen is 1% bent, i'll claim for another device as I still have my warranty.

Yes, for the reason Samsung care told me that until my phone does not have symptoms I can't take it back for warranty.

Wow with this I think most of our Z1Cs can be heavy utilized and still last three days easily...

I went and ordered one. I'm wondering (if I don't mind the extra bulk) if I can just leave it in the case and keep the case charged up via USB. Has anyone else used this type of battery /case before?

I think that could be doable, if the case have an "off" switch so that it does not charge the phone all the time.
I think its inadvisable to charge the phone from the case while the case itself is charging, at least that was the case (no pun intended) with the external battery case I had for my old galaxy s2.
please make a quick review when you get the case!
(the one i got for the s2 was advertised as 2200mAh, but in use it was not even 1000mAh, it only charged the phone about 40-50% even if the phone itself was turned off while charging from the case. I kept it anyway since it was quite convenient to charge the phone "in the pocket" so to speak)
//Gunnar

From the brando link:
" Please Charge the Battery Case and Sony Xperia Z1 compact / Z1f Separately. (Do Not Charge the Battery Case and Sony Xperia Z1 compact / Z1f At the Same Time)"
Looking forward to a tiny review aswell
Regards,
Yoko

I wasn't exactly sure how to interpret that, since it would actually be possible to connect USB cables to both parts simultaneously.

Not to be a "mister know it all", but I think the micro usb port on the phone is covered by the case. it looks like it in the pictures anyway.
//Gunnar

Very observant, you are correct, sir. I guess that answers my question.
This phone already has great battery life- I still had 80% left when I got home from work yesterday, so I guess the extra battery might come in handy for camping trips and stuff like that, but I wouldn't want to have to take it out of the case every time I was charging it. Daily use might not be practical.
I'll post my first impressions of it as soon as it gets here and I've had a day or so to play with it.
dave

No worries, the instruction manual explicitly mentioned that you can certainly charge the phone while it's attached to the case, and it will charge the phone first before charging the battery. :good:

Unfortunately for me, it arrived with a broken packaging case... I reluctantly threw it away due to the sharp broken edges. The case itself is fine.
You can see that the case is drawing about 1 A input to charge the phone first (charging the battery does reduce that to its specified 800 mA rating)
The connector, overall I will say the case is well-constructed. The clips latch on the the phone easily and yet firmly, so you don't have to worry about them separating accidentally or scratching the phone's metallic frame. The dimensions are spot-on and it feels good in the hand.
The positioning of the microUSB port meant that it can even prop the case up vertically.
Here, you can see the tapered side profile and unobstructed microSD card slot. This is one advantage over the equivalent version for the Z1.
The cut-out for the camera is just nice, and you should also be able to see the glossy white surface. I had the impression it was going to matt from the Brando website's photos though, not a big issue...
The kickstand in action. Unfortunately, this is where I have to deduct some points off the case... the kickstand is a little short and requires an absolutely flat surface to be stable. It is quite easy to push the phone over otherwise. In other words, it gets the job done, but just barely.

Mine came in last night, and the box it came in was also cracked in one corner. Your review is spot on. I got the black one, which does have a matte finish. The only thing I would add is that they could have rounded the hard corners a little bit more to make it a little more comfortable in the hand. It does double the thickness of the phone. I always carry mine in a holster, so that doesn't bother me a bit, but it might be an issue if you normally carry it in your jeans pocket. It will take a few days to see how well it works, but overall I'm pretty happy with it.

I am very interested in hearing back about the battery capacity, about how long the phone can keep going when both batteries are charged.
Sent from my Nexus 7 using Tapatalk

Sorry to burst the bubble of anyone monitoring this thread, but after weeks of usage, I realized the battery capacity does not live up to the claims on the website. My observations:
The battery is fully depleted in about two hours, and can only recharge no more than 70% of the Z1 Compact's internal battery. This puts the actual capacity at around 1600 to 1800 mAh.
The battery indicator is not well-calibrated. According to it, the first 25% of the battery is depleted in about 10 minutes, and the next 50% is depleted in almost 2 hours, meaning about 25% in less than hour. The last 25% is also depleted quickly. The discharge rate is inconsistent with the constant charging rate I see for the Z1 Compact's internal battery.
My testing was done while the phone is idling, and I wasn't using the phone at all while it was being charged by the Power Jacket. Wi-Fi is enabled. I have feedback this to Brando Workshop, let's see what they have to say... maybe I got a defective unit.

You must have gotten a defective unit. I haven't done any kind of exhaustive tests, but mine charges the phone from around 70% back up to 100% more quickly than the wall charger does, and I've hardly put a dent in the external battery charge. I'm pretty confident I can use the phone pretty heavily for a couple of days between charges.
Mugen Power is now making an external battery case for the z1c, but I haven't seen any pics of it yet.
dave

Have you tried to fully deplete the Power Jacket? E.g. run the Z1 Compact down to say 10% battery life and then see if there's still some power left after charging the phone fully.
I suspect your wall charger is charging slower than 1A, because my wall charger can deliver 1.2+ A to the phone easily through the magnetic charging contacts or micro-USB.
Maybe it wasn't mentioned clearly in my original post, but the Power Jacket does seem to charge my phone in the region of 1 A, I'm just dismayed that the capacity on mine is so weak.

I'll have to give that a try and get back to you. I was a little curious why the Mugen costs so much more than the Bando (it's around $90).

I ran my phone's battery down to 10% yesterday, then charged it with the battery case, which was fully charged, and I got similar results to yours. I'm not sure that this means a discrepancy from the claimed capacity of the battery case, though. I'm not an electrical engineer, but theorizing that when the amount of charge in the case matches the amount in the phone, there is no longer a voltage differential to move a charge from one to the other.
In other words, if you were charging a dead phone with a fully charged case, only about half of the capacity of the case would move to the phone, which would be about 1600mah, which would only provide about a 70% charge. That matches the numbers you came up with. As long as the case has more charge than the phone, you'll still get a charge from it.

That's not quite how a battery charging works, but if it does, then you should be able to charge the phone again when its battery level goes down.
I seriously doubt that's possible though.
//Gunnar

Battery voltage drops as it loses its charge. An external charger connected to a power source will maintain sufficient voltage to fully charge a battery, but with the battery case you're basically just connecting 2 lithium batteries in parallel, so the current will only move as long as there is a voltage difference between them.
It's possible that the more expensive Mugen case has additional circuitry to maintain the higher voltage to fully charge the phone's battery.

Hello Guys
I would like to buy the brando battery case but I have a question, why is not possible to charge phone and buttery at the same time?
I understand that the battery case will cover the micro usb port, but what if I cut it to uncover the port?
thanks

It's not necessary to remove the phone from the case while charging. If you have the case turned on, the phone will fully charge first. The case will then shut off from the phone and charge on it's own.
