Mugen extended 4800mAh battery

I recently got mine and I will leave a review on it on this thread in a week or so. Apparently the battery gets better and better if you charge it right, after about a week. That and I have a couple programs I'm trying, to correctly recalibrate it. Battery Left widget, Battery Monitor, which measures it by mAv rather than regularly. And Battery Calibrator, which deletes the battery file in the phone, and remakes it. I have the most hope in that one. Can anyone else give a review on a good program to CORRECTLY calibrate this battery?

i purchased one of these myself a while ago and unless quality has improved, i was hugely disapointed for the cost
the 2 internal elements of the battery are 'stuck together' with a black tape style surround. This causes after some use of separate device charging ( charging in a charger and not the phone ) the battery to lose its shape causing the streak to think a battery is not present
the life of the battery itself is good, but the.g

but the general quality of the product is very poor
the back case, with plastic clips is also useless after some use
these clips break, simple as
even the ebay ones of a lesser power have backs with metal clips on
mugen, im afraid i cant recommend your product, simple as

The 4800mAh one doesn't have a clip. And the only thing I don't like about this battery is the fact that the cover is plastic. But I'm in love with the battery itself. I've done everything I can to make it die. Streak's overclocked to 1.2gHz. Backlight's up. Bluetooth is on. Wifi is on. Even been playing music a -lot-. It's been off a charger for 83 hours.

Update. The same thing I love with this battery, I also hate. The instructions said to charge to 100%, let it die, and repeat for about the first 5 charges. I haven't been able to do this, and I -have- to charge it tonight. I don't even know what percent it's at, which is driving me crazy... I'm literally trying to get the battery to die... This is a mere annoyance, for now, though... I'm sure I'll get used to it... I'll just charge it every 3 days, or something.

My battery JUST died! Lol....Atleast 60 hours of use, with atleast 10 hours of playing music...

wow 60 hrs is hectic.. i might get me one aswel

60 freakin hours? Crazy stuff! Tempted to also get one.

My first charge was over 86 hours.

I see that all the Mugen Extended battery posts are from August so I have to wonder if the battery issue has been fixed. When I got my battery it would give me 3-4-5 days .. then as soon as I upgraded from 1.6 to 2.1 or 2.2 I would get a low battery warning long before my battery was used up. I had to remove the battery and turn it back on for the warning message to go away. Besides that being a pain in the butt, you have to be VERY VERY careful to not break the plastic clips .. I could get by with one broken off but sometimes the phone would shut off .. so ... Are you all not getting the low battery warning ?? I contacted Mugen often and they couldn't figure out the problem. they said the problem was with Dell and Dell wouldn't tell them how to fix it.

Well, on my last charge, I got the low battery warning after 3 days...You have to delete the battery stats file then charge it to 100% and let it die. It calibrates it a bit better, atleast.

I have read other posts that state that these extended batteries use a pack that actually contains two batteries and that power cycling the phone when it gets to or near zero causes the battery meter to properly read it after it has switched to the second battery.

I bought mine when they first arrived at Mugen. I don't remember how long ago that was but I was posting daily my battery status. Probably a year ago. I think I got 4 days. Not heavy usage. I was on T-Mobile Edge. That was before I upgraded from 1.3 to 2.1 or whatever it was. IMMEDIATELY the Streak could no longer read the battery. It isn't really 2 batteries hooked together .. or maybe it is .. there is the part of the battery that fits in where the original battery goes and then the rest of the battery is the size of the cover .. but thin .. Any way .. It would tell me that I needed to re-charge, but all I had to do was remove the battery and replace it and get more life from the battery. Still .. it never felt as long having to remove and replace. If I remember correctly - resetting the Streak didn't do the job, the battery needed to come out. It was a pain because the cover isn't metal and the little clips are plastic .. BE VERY CAREFUL removing the cover. Mugen will replace the cover but it sucks having to treat it so gently.
Whatever ... in the end. NO PROBLEMS with the original 1.3 version .. THAT could read the life of the battery correctly. I thought by now one of the XDA people would have come up with a fix. I think I won't buy another until there is a fix. If you have to constantly take it out and put it back, may as well have 2 of the regular batteries. Then you don't have to worry about that CHEAP plastic back cover.

I found this post of mine from BEFORE I UPGRADED to 2.2 ..
http://forum.xda-developers.com/showthread.php?t=831282
at 10th November 2010
"Today has been 72 hours since I unplugged it from the charger and I am at 58% .. I am not going to put it on the charger until it won't start !!"
I don't know where I posted after that ... but I know I got at least another day.

Well, they tell you on the site that it won't read the battery correctly.

Mugen didn't know that it wouldn't read the battery until people started complaining after the 2.2 upgrade. I know this because I was one of the first to buy the battery and the first to get upset after I upgraded.

Well...If you've ever used Battery Dr., they calculate how long you can use music, video, 3g, wifi, etc. And since this is approximately 3x as powerful as the regular battery (Mugen says 3.14x) I just extended the times to calculate, by 3x.

Cool to see people having success with this.....I think I'm going to spring for the 1800 mAh battery from Mugen and see how it works. Not really into having a flimsy extended case for my phone. Even though multiple day charges would be nice, I'm just looking to make it through 10-12 hours.

New battery = amazing new life for my Nexus 5!

(cross posted to Nexus 5 subreddit)
So I've had my N5 since it was first available (ordered it the first day it was on Google Play). Over the last 6 months or so, I've had absolutely atrocious battery life, which I attributed to the upgrade to Android 5. Most recently, the battery life has been so bad that I could be at 98% and after 10 or 15 minutes of playing a game with GPU usage, the phone just shut down. After a reboot, the phone said my battery was at 1%. Then I'd keep the phone off, leave it for 20 or 30 minutes and when I turned it on again, it told me the battery was at 40%. Super strange.
Long story short, I decided that my battery had some real problems. So I took a chance and ordered what looked like an ok battery replacement off of Amazon (link below) as well as some tools from iFixit.com (link below) and decided I was going to try to install a new battery.
Well, it's been about a week since I did the battery replacement (link below to the YouTube video that was helpful) and my phone feels like a brand new device. I get a real, full-day use of the phone now, which for me is having it on and using maps, Gmail, texting, Chrome, Facebook, Play Music, and a few other key apps. Some games here and there. I also obviously have the phone off during the day when I don't need it. Before the battery replacement, my phone could easily be dead with a mix of screen on and off time in 2 hours or less. Now I'm getting 13-14 hours easily. Really amazing.
So I thought this was important enough to share with everyone. If you're in the same boat that I was, you might give this a shot too. Here's everything you need to do what I did:
BATTERY (ships from Chicago, NOT China! this was key!): http://www.amazon.com/gp/product/B00LD7S6YQ

YOUTUBE TUTORIAL: https://www.youtube.com/watch?v=UlmKLfgUtBQ
Here's some additional info about my setup that may be helpful: ROM: Cataclysm latest stable build (built off 5.1) KERNEL: Elemental X 2.11. Also using Greenify to hibernate unnecessary background apps
Feel free to ask any other questions. I'm really pleased with how things have gone with this new battery (at least for this first week, which I know is not tons of time). For the moment, it feels like I have a brand new phone!

I was just starting to look for a replacement for my N5. This one doesn't get the greatest of reviews. I've wasted $13.50 on worse though. You still recommend it?

I do! Granted, I've had this for just about a week so it's not the best assessment of long term performance but the difference between the dead stock battery I had and this new one is night and day. I can go all day with this new one. I could barely go an hour with the old one before it shut off. Worth a shot -- and to your point it's only $13.50.

Great thread!
But I think my battery still no dead, can get 3.5 hours of SOT with like near to 2 hours gaming, and it can still standby for at most whole days with such usage
Now in stock 5.1 with elementalX kernel

ONLY fresh year battery to buy
I hope for a long battery manufacturing. Unfortunately, the design of batteries is that they are prone to aging. Even if they are in a store, they begin to lose capacitance over time. It is necessary to carefully examine what year battery you want to buy

Hmm, also considering replacing my battery...
One day my phone was going haywire and I took it apart (easier than I thought) replugged the battery cord and worked fine after that.
Probably anal but right when I unplugged my phone from the charger just now it went from 100% -> 99% instantly.. dun dun dun! lol I've had my phone since December 2013 so yeah you can tell how long I've had my phone for! haha

I ordered one from etradesupply that will arrive tomorrow. I hope it has a fairly recent manufacturing date and isn't some extra stock from 2013. I know I am paying more due to shipping but buying batteries on ebay makes me so nervous about fakes and the quality. At least it looks super easy to swap out.

Coincidentally, I came to the same conclusion yesterday and ordered a new battery. It appears to be something of a minefield and you can pay between £8 and £30 for what seems to be the same battery!
In the end, I went with a mid-price battery from a reputable seller and hopefully all will be well...quite excited for it to arrive

My new battery just arrived today! I'll get it fitted and update with how it is. I've got some screens of battery life at the moment. Hopefully it improves

My etradesupply battery arrived yesterday. It looks exactly like the stock battery and shipped from Texas. Manufacture date is September of 2014... Can't remember the exact date but it for sure september of 2014 which is older than I'd like but we'll see. It was at 47% charge which is about what it should be for storage.
I haven't had a chance to do a full cycle yet. I just charged it to 100% once so far. My screen on time is 2 hours 15 minutes with 34% battery left. I don't do anything special to conserve battery and use automatic brightness set to 50% or whatever stock is. That's a mix of games and browsing.
I am not sure if a new battery has to go through a full cycle to get calibrated or anything like that. I've read laptops should be drained completely once in awhile (not often) to recalibrate something with how the battery life is measured. I feel battery life is better than the battery it replaced so far which is what matters to me. If I can get 3+ hours SOT consistently I'll be happy. I was getting down to around 2 hours SOT on my old battery.

I've been contemplating getting a new battery for a while. I have a launch week device so my battery is sitting around 18 months old. I'm not getting terrible battery life but it's not as good as it was either. My usage patterns have changed since then and I also keep a lot of apps installed and have everything turned on as opposed to when I first had the device I had a script remove most everything from the phone and kept most things turned off. I'd say an average work day I'll see 2-2 1/2 hours screen on time with about 1 1/2-2hours bluetooth music playback. I'm looking for a charger around 6pm when I get home.

i see you're in the US so not sure if I'll be of much help. I ordered off ebay, just checked to make sure there was plenty of feedback for the battery. Just using up the battery of my current one so will change tonight and hopefully update tomorrow!

Good to hear OP! I always look forma back up bstteryied con amsozn

Just my luck. I get the one battery that doesn't charge ? have to wait on a replacement now

Every one knows batteries need to empty and fill a good few times to reach peak holding. I replaced mine with a genuine OEM, from Amazon, and it took a good few days then it made a huge difference longevity. Never buy cheap batteries. They are fake and can't be told from the real thing until you use it AND findout. Go by the reviews and who is selling

Battery Replacement in India
Where can I get the battery in India. My battery too draining like hell..
Can anyone suggest where I can get battery in India.. Online website is fine

I have my old battery replace at the official LG service center here in Manila and all i can say is that my 5's battery life is just like brand new. After a year with the old battery, sot max is just 1.5 hours, after the replacement, 4.5 hours.

[Not a post about battery life] What keeps killing my ACTUAL PHYSICAL battery?

So about 6 months ago I swapped the midframe and back on my N6 for the Moto X Pro ones. While I had the phone apart I replaced the battery. My original battery was still functioning fine but I figured since the phone's already torn down, why not replace it? My plan is to keep this phone until the 2016 Nexus is available. So I wanted to be sure that the phone would be problem-free until then.
I got the new battery off eBay from one of the many Chinese electronics retailers for around $15. It was sold as a Motorola OEM battery. When it arrived it looked identical to the original one out of my phone. Installed it, charged it up and went about my business. About 2 weeks later the phone e starts ****ting down suddenly. At first it would do it somewhere between 20%-30% on the battery meter. Then it progressed to shutting down at 50%-60%. Finally it would last only 10 minutes after taking it off the charger (at 100%) before shutting down suddenly. When it would do this, there wasn't the "shutting down" animation you would normally get from running out of juice. It would just go black.
So I deduced it was a junk battery and ordered another one. This time, I ordered one from a place here in the U.S. It was more expensive but not by much (around $30 I think). It arrives, I install it, works great for a month, then starts shutting down suddenly just like the eBay battery. It's at the "only lasts for 10 minutes off the charger" stage right now. So that's battery #2 that's suffered the same fate.
I have battery #3 on the way and it should arrive on Monday. Ordered from another U.S. retailer. Spoke to them on the phone and was assured that it's a brand new, OEM Motorola EZ30 battery. So we'll see how this one works.
At first I was sure I had just received a bum battery. But after the 2nd one had the exact same problem in such a short amount of time.e I can't help but wonder if it's something else causing the failure. 90% of the time I charge the phone via USB and the wall charger that came with the phone. The other 10% of the time it's charged via USB and my old GS4 wall charger. Would using a different charger cause battery failures? I had used the GS4 charger with the original battery that came with the phone and had no problems. Also, for a couple months, I had used a Cheotech 3-coil wireless charger. But I didn't like how long it took to charge so I quit using it. I used it for about 2 months on the original battery and the 2 weeks of the first replacement battery's short life. I haven't used it on the 2nd replacement battery at all as I was trying to see if that may have been the cause of the 1st failure. Can using a different charger damage the battery in such a short period of time?
Is there anything else I can look for before putting in battery #3? Like I said I'm hoping to keep checking this thing alive and kicking until this fall when the new Nexus is released.
Thanks.

Your batteries (#1 and #2) were not damaged by your usage pattern. They were bad quality period. And now you are paranoid about that. Those two batteries being bad does not surprise me at all because the inherent longevity of a battery is closely related to how well controlled the manufacturing process is, and we know how well that process is controlled for Chinese cheap batteries.
Modern batteries and chargers are built in a way that make them relatively immune to user abuse. Your battery lives for a certain number of charges and discharges. For a good battery from a reputable manufacturer that is around 500 to 1500 times. There is also a second order effect that if you recharge the battery before it completely dies it lives marginally longer. That is about it. The stuff you mentioned didn't cause your batteries to die. The poor manufacturing condition in a sweat shop in China did.

I think you also shouldn't use turbo charger with these batteries.

The battery's microprocessor regulates the charge and is designed to prevent damage to the battery. Thus this statement is ridiculous. Especially since all turbo charge does is allow more energy to be transferred to the battery in a given unit of time than with a standard charge.

okay. Its my bad then. But i always notice that my phone heats up more when i use turbo charger. And heat is never good for these batteries.

The amount of heat generated on charging does not significantly impact battery life when compared to something like doing a deep discharge. I wouldn't worry too much about the heat. The battery can handle it.

I see thanks for clearing things up. I saw those videos and images of nexus 6 with all those popped batteries and back covers. I have been afraid of its heating up since then. So i can use it without worrying about its battery and back cover?

I've had my Nexus 6 since the beginning of the year and have had no problems with it whatsoever. While there is no guarantee you won't encounter a problem, if your Nexus is relatively recent like mine you shouldn't have any issues.

New battery, original or fake?

Hi,
Yesterday i buy new battery for my old lg g2, but i'm not sure is it original.
My New battery is non stepped like this http://tanstartrade.ca/images/LG%20BL-T7.jpg
Do you think that it could be authentic?
Thanks in advance for your help.

I just got replaced battery in service - they told me that they use original LG parts. When I checked it under the cover, it shows manufactured date 6th of January 2016. It is not allowed by antena strips and curved back cover to have thicker battery and thinner would have less capacity. You could probably try but I don't see any benefits in that.
EDIT: After few days of usage I had to get my battery replaced by the old one. May be bad luck with not properly working battery but more probably faik one (runs for 0-10 mins, weird force charging in no OS mode). When they showed me the "new" battery in service it is thinner than the original, does not have the stepped back and thus makes gap between back cover and battery itself - 2mm of medium hard press. So it was like yours - flat design - no additional stepped part. The service was not authorised service but looked legit and had plenty of good reviews. So it's my experience of flat lg battery replacement stated as original.

Be noticed that all of below information are not yet confirmed.
I discovered the difference between original and fake since searching trough forums and own experience. :victory:
Design od LG BL-T7 battery has not changed ever since. Still the only one with the stepped back side. Should look like the battery on right side of these pictures, otherwise it is nor factory replacement (aka fake):
http://i.imgur.com/2Yt8cvDh.jpg
http://i.imgur.com/hkVpceYh.jpg
http://i.imgur.com/XtEH5AQh.jpg
The main difference is in litle bulk under printing "BL-T7", arrows under the NOM icon and next right is noticeable differnce in T in that symbol, fonts differ and last letter of chineese behind the manufactured day,...
There is a believe that non-original batteries are not that bad at all, only they have poor wiring and connection port which often makes them behave unexpectedly.

Note that if you face any issue regarding charging since these batteries are years old, then feel free to contact the seller and you will get a replacement.

I bought that same battery. It had no glue residue and the year was rubbed off.
It looks genuine but I won't be able to tell until my replacement screen arrives and I can install them both at the same time.

I bought a 3950mah high capacity battery from aliexpress (so clearly not geniune but for the money I decided to give it a shot). it works fine, got my Screen on time from 2-3h to 5h or more. However, when charging, it will charge up to 95-99% and then, while still plugged in, go down to 83% and stay there. Then when I unplug it and start using it, it first goes back up to 90-95% before going back down like normal. Has anyone experienced something like this and/or know a way to fix it? I tried some battery calibration methods but no luck. Also, since the phone rarely reaches 100% (indicated) it doesnt always reset the screen on timer properly... this makes it difficult to keep accurate track of its performance. when it does work 5h seems to be the usual value.

That one sounds weird.
Definitely not normal.
Only solution is to buy another and test it or return the one you haveDefinitely and try another one

I have contacted the seller but so far they are not replying... I tried the Ampere and 3C Battery monitor the check the voltages and currents while charging. At first, I thought the phone showed the wrong percentage as it was not calibrated for the high capacity (so 80% was actually 120% relative to the standard battery capacity) but it showed that the phone was actually discharging once it reached full charge. Also, my assumption of it being 120% was wrong since the percentage probably comes from the cell voltage. So, next I checked the cell voltage using both ampere and 3C but the values were all over the place, jumping from 4.36 to 4.2 and back. this made no sense. The battery has a top voltage of 4.37 when fully charged so maybe the battery monitoring software of the phone is confused by this?
In any case I will wait for the seller to get back to me and if the problem becomes worse I will get a new battery to test out.

Thanks for the update.
Keep us posted on how it goes.

So, next I checked the cell voltage using both ampere and 3C but the values were all over the place, jumping from 4.36 to 4.2 and back. this made no sense. The battery has a top voltage of 4.37 when fully charged so maybe the battery monitoring software of the phone is confused by this?
In any case I will wait for the seller to get back to me and if the problem becomes worse I will get a new battery to test out.

Hello guys, I am looking to buy new battery for my 2 and half years old g2. So here are my options:
1) Pollarcell - they says it's great battery, but still kinda expensive for a non-oem battery. It would cost me about 25e.
2) OEM LG battery - in LG official service, I have to check it they still got them, price was about 30e if I recall correctly.
3) Some random battery - I guess this is lottery.I can get good or I can get bad battery. There are many brands, and their price is from 8-9 to 15e.
OEM is best choice for sure, but I don't feel like investing 1/3 of phone price in battery, especially cause I don't know how long I will keep that phone. Dunno what to do
Edit: Did anyone tried this battery? It has quite high rating

Beware of Pollarcell batteries I have read cases of burning

Bought my new battery at PhonTrading24 ,
Battery is class and from new production 12/2016 .

fake or original?
I also changed my battery after 3 years at LG service however I have some questions in my mind whether battery is fake or original one. Although new battery has same capacity like old one but it doesn not last like new one ( it lasts almost a day ) Pictures are attached new and old one. What do you think guys?

It looks like the original one and it might well be. But that also means it is not new, as the production of original batteries have stopped several years back. So what you have is probably an unused but ageing battery.
Batteries start degrading the moment they are produced, just that it degrades at a slower rate being unused (depending on temperature it's stored etc), compared to it being actively used everyday.

thanks a lot for the comment. I have been using this battery for a month now and the battery ends after completing one day. As and old production not bad as you said.

Dimensions of original battery BL-T7, taken off from LG G2 : 55.4mm x 66.4 mm x 5.6 mm (thickness in the middle), Weight: 45 G.

Upgrading the internal battery

I'm curious if anyone on here has tried opening their phone up to swap the battery with an upgraded mAh cell? There are 4,220mAh upgrade batteries all over eBay and I'm really about to pull the trigger on one of them. If it fits and works properly, that is a pretty substantial upgrade in screen on time daily and the difference between me having to charge one to two times in the middle of the day versus being able to go the whole day on the initial charge.

Just cause the listing and label on the battery says a capacity doesn't mean that's true. I wouldn't risk putting in a 3rd party battery that costs $20 (for example) into a $600+ phone

Well I mean that's a given with anything you buy on the internet without seeing it first. As for the price of it, a genuine OEM Pixel 4 battery is $25-$30 so I'm not put off by the $10 difference in price. I also am not going to be relying on the battery if I try it, as in if it turns out to be a dud I would just immediately swap back in the OEM battery and take the little $20 hit but I think its Worth trying with the current risk to benefit comparison and if it ends up being truthful, even if it's not 4220mAh but more than the OEM 3700mAh it would be a win in my book for the price. I have an inline USB meter I can throw between the charger and phone to measure how many milliamp hours the battery actually took.

If you need to upgrade battery to get more screen time each day then you're using your phone too much lol

After my experiences with purchasing piss poor quality aftermarket batteries off Ebay and elsewhere (N6P), I would not recommend it. For the same price you can buy a PD power bank that will fast charge your device anywhere you don't have a charger handy. That and you won't break the back glass. Of course, it would be a totally different story if your battery has somehow degraded tremendously and is now defective. I'd be curious to know what your current battery capacity is using Accubattery. When I bought my P4XL, it was 103%. 6 months later it was 98%. If your battery capacity is still 90-95% I would look at a decent PD power bank and not crack the case open. Even if you pay someone to do the work and get a warranty, your phone will never be the same. Best of luck. :good:

I would think that a battery that's 500mah bigger might not be able to fit in the phone... Chances are that the battery will just be a low quality replacement.

According to accubattery I currently have 12 hours and 25 minutes of screen on time. I dont know about anyone else but that is really good in my book and more than enough. My battery is reading 103% capacity.
I never fast charge my phone unless I forget to charge it overnight and I am leaving the house soon then I throw it on the original charger. And I almost never charge past 80%. I actually use a device called chargie that slow charges my phone overnight. It completely shuts down the charger at 80 allows the phone to discharge to 76 and kicks back on and goes back to 80. My battery only goes up about 10 degrees F while charging. And I have it set to shut off the charger if my battery reaches 110 degrees F. I really plan on keeping this phone for at least 3 years (since I have a family and I have to be a big boy and put food on the table now) No more getting the newest phone for me every year.

Well, considering my phone is used for all traditional purposes (YouTube, social media, email, web browsing) along with the fact that I run my business from my phone, you wouldn't be wrong, but it is essential and serves it's purpose. Any extra sot I can get is a huge plus for me.

Yeah I feel what you're saying, the one reason I haven't already dove right in and tried is the splitting the case open. I have don't it once before on a P4, my last one had some issues and I was able to open it up before sending it back to Google to be RMA'd.
I do in fact have a 10,000mAh PD power bank, I bought it within the first week of upgrading from my P2 to my P4. It works fine and is a great solution but obviously being able to fix the root problem would be better if possible. The power bank is along the lines of a bandaid for the problem but seems to be my only logical choice for now.

12 hours screen on time? What alternate plane of existence do you get that kind of SOT with a P4XL??

I just opened up mine the other day to replace the rear glass ( had a crack in the corner). Was pretty easy with the guitar pick looking spudger. I did not need any heat to open it. Figured while I was in there might as well replace the battery with a fresh one. Both were purchased from ifixit. The swap out went fairly quick, I just took my time to scrape all the sealant from the edges of the phone for the back glass to have a good seal. Haven't dunked it yet to test if its still waterproof.

No I actually never ended up pulling the trigger on it. To be honest, I'm still really interested in the idea. The only slight bit of anxiety it gives me is with breaking the factory adhesive on the rear panel. Still, I will try it soon. I hate having to dedicate a pocket to my power bank anytime I'm out for more than a couple of hours.

What adhesive did you replace the factory stuff with and where did you get it?

The 3 pull strips for the battery didn't fully come off so there was still some that I could reuse to secure the battery. The rear glass that comes from ifixit has everything (nfc,qi, camera lens gasket etc) already attached to it including the adhesive. They also sell just the adhesive strip by itself if you're just opening it up.
