Disclaimer: I know there is already another thread on Mugen HD2 Extended Battery 2,600mAh, but I would like to state that this is an official review since Mugen has provided me with a review unit to debunk the many bad comments given concerning their battery quality. This you can read from http://forum.xda-developers.com/showthread.php?t=1294124.
[BACKGROUND]
I have contacted www.mugen-power-batteries.com directly after hearing many comments concerning their false claims. I was surprised that they actually responded by providing me a review unit of the 2,600mAh. It is now on the way.
My review unit will be coming in about 2 weeks time. I will try to conduct an extensive review to determine the actual worth of the battery and whether they work as advertised. I will be conducting a few tests specifically on the battery, as objectively as possible. This would cover video playing, 3G usage, full valuation of the battery charge (using battery widget pro) to name a few.
If you would like a particular test to be conducted on the battery, please state and give a few ideas below. I will be comparing them against the original 1,230mAh from HTC.
I think as faithful users of our HTC HD2, I would really want to get the best extended battery. If this provides even 90% of the advertised capacity, it is already worth the money. Anything less would be pointless.
Thank you.
Larger cell will indeed be good but 2600mAh will be higher than reality as Mugen have admitted this already in a round about way on responses to another testers results.
A new standard HTC cell & new standard size 1500mAh Mugen is the test that needs to be done.
Any chance of a sample 1500mAh review unit ?

I will try to get a 1,500mAh review unit after this one is done Oh, have Mugen admitted to that? Would be good if you can provide me with the link. Thanks!
Cant Wait for the review
Im Planning on getting one myself a 2,600mAh

This was response to Dougs battery testing.
Not in any way slating Mugen but the mAh ratings marked on their cells are higher than what would be achieved in any lab test.
1500mah is the one I would love to see tested side by side with genuine cell in device & technician mAh testing.
Mugen cells are ok quality but for the asking price we need total transparency on actual cell capacity ...
I have no idea how good that battery is, but I bought this one about 6 months ago and it's working very well, doesn't gain much heat and it doesn't discharge itself much. Average battery consumption in standby is 6mA. All I can do is recommend you guys this one. And cover is really strong. And it's "bit" cheaper than Mugens
[email protected]/MB434B/review_MB434B.html
looking forward to seeing your test results...i just got me a 2400mAh battery and it lasts me about 15hours under heavy use...
Hi guys,
Sorry for the silence... I just received the battery today! Give me some time to get it charged and conditioned for testing
Let me know what else you would like me to test it with.
Display use is interesting for me, such like browsing etc.
Open a browser with some ads or something and look how long the Battery live..
My Galaxy SII gets there 4,5h.
Start the Match
Idc really care about that battery. I know its fake, but is there any real battery that's better then the original stock? 1400, 1450, 1500?? Not the fat ones with the kickstand
Just an update, I am still conditioning the battery. The first charge/recharge was really pathetic, at 12 hours before it was flat (moderate-heavy use). The second charge/recharge is much improved, I am on 25 hours on (moderate use) with 25% left (taking pictures, listening to music, games, surfing, etc.). I will begin formal testing after 4 full runs to find the optimum condition.
One things I have to say is that the ROM does play a high factor. I was on Dorimanx 3.0 and somehow the governors for oc/uc is not working properly as I kept getting some high drainage. Once I reverted to 2.9, the drainage was gone and it seems to sip battery at a much, much lower rate.
So many factors!!!!
By the way, I really like the battery cover. It is not cheap like the other China made products (unlabelled). I have already 4 different covers, and while I would prefer a metal back cover, this is the 2nd best
Can You please also start the heavy display usage test?
And put some pics please
Greetings

I have a few questions which i hope you dont mind answering:-
1. How did you recondition the battery?
2. Does your kernel recognise the battery's full capacity or do you do a battery pull then it jumps back up significantly? Im facing this problem at the moment...
thank you in advance!
how long will the battery last for heavy use like playing 3d games?this is important as i use my phone for gaming most

1) I conditioning it by charging it overnight for 6-8 hours and then depleting it until it powers off (Actually, this is based on the instructions they gave in the parcel). I need to do it 5 times. Once done, I will be able to charge and stop charging when the indicator hits 100%. I basically use Battery Widget Pro (they have a feature called 'calibration'). Apparently, the battery itself states that it is 2,300mAh, but I think this is not accurate (hence the testing). You will know that the battery is fully charge when the indicator goes down to 0 (zero) mA (shows that the battery is not receiving any more charge).
2) Most cheap batteries have wrong indicators (e.g. temperature detection is not working, no indication of battery capacity). And yes, they suffer the need to 'pull the battery out first' before an additional amount is given. I bought one a while back, apparently one that has 3,000mAh. My observation is that the indicators are really gone. In fact, it will slowly go down to 50%, after which if you pull, it will give you 70%, once it goes down to 15%, it will last for a long while (30 minutes of browsing over 3G) before going down to 14%. Using that battery, I have been able to last 31 hours of moderate use (1 hour of music, 1 hour of gaming - not 3D, a few hours of browsing and a lot of photo taking). It costs only USD12 (thereabouts), which to me is the best deal yet. Down side of that battery is the very poor back battery cover. Using Battery Widget Pro (you have to charge fully and discharge until it shuts down and charge up again continuously), I got an estimated charge capacity of 1900mAh. Not bad don't you think?
The Mugen 2,600mAh easily matches my fake 3,000mAh one. The question is by how much. Sorry for the delay but my HD2 is my daily phone. So, I cant conduct full test like Engadget and other websites. But I'll do my best

Try Andida batteries. I had the 1600mAh one and it was slightly better than the original (giving me about 1300mAh). I had that a while back.
After much charging and recharging, I can confirm that the battery has about 2,200+mAh. See the attached images to see the estimated calculation using Battery Widget Pro.
Charging takes about 2 hours plus using the wall charger. The last 2% takes the longest.
As per request I ran 2 emulation apps (sorry, no 3d games), fpse & n64oid. The former ran Strider 2 while the latter ran Legend of Zelda: Ocarina of Time. Do note that I have overclocked my phone to 1.6ghz. All in all, it ran for 4.5 hours with 15% battery left. I'm pretty sure it could have clocked 5hours easily. I think that it is a good performance for 2.2kmAh battery don't you think? See the images below for a read of what other apps I was running. I managed to deplete the whole charge after nearly 10 hours of extremely heavy usage!
What do you guys think? Okay?

[Not the Mugen 2,600mAh Battery]
As an aside, I took and strip out the cheap battery which I bought for USD10, which claimed a 3000mAh, which only was about 2000mAh (+/- 200mAh) and took some photos of it. I can understand these extended batteries better. I am not an electronics person, but this would explain why it takes a restart to 'recognise' the 'remaining' battery on our devices.
Notice that they are basically two lower capacity batteries which are slapped together with the thin connectors and wrapped together with scotch tape.
I am not sure whether Mugen's the same, since it does not suffer from the 'restart-phone-to-get-additional-battery-reflected' scenario. However, I wonder whether there are any manufacturers who would just manufacture a genuine 2000mAh without merely slapping two products together (like in this picture). In light of this, it is much better to carry an external battery charger (anything more than 6,000mAh around!).
Anyone with electronic expertise want to comment on the pictures, please do.
Opps, forgot to add the photos of the battery and the battery cover which I mentioned. I find that after the first fall (yes, I tend to have accidents with my HD2 ... ) there is a slight creeking sound with the battery cover (nothing is chipped though). It is a rubberised battery cover, unlike the original metal cover. Still, the feel of the cover is great to the touch.
I am no longer using this device, but my dad is! It still works and have survived loads of damage... mostly dropping the device with the battery cover!
As per thread title, looking for an extended life battery - but dont want to end up with one that comes nowhere near what its rated for....like the 5400 mh battery I bought off ebay last year. Its so poor, it doesnt even last half the length of the standard oem battery!
Does anyone have an extended life battery for the n7000 that actually lives up to the declared spec??
Hm not that i know off.
You might want to turn your screen brightness down, ive found that matter quite a bit.
As for batteries with more capacity... Well youve said it, tho its a bit weird if the batteries capacity really measures 5000mah(?) It should ofcourse last.

I've tried that - but in certain circumstances, its simply not practical - if out and about somewhere that its sunny. I've gone back to setting it to automatic in this respect - so it adjusts to conditions.

I guess they should. However, around the time I bought that battery, there was discussion on here re. the expensive mugen batteries - and that they were not coming anywhere close to the rated capacity. There were mixed reports re. other chinese batteries - some good, some bad. I took a punt on that battery - it was cheap - but it turned out to be rubbish.
Perhaps the way to go is one of these portable power packs rather than a replacement battery? However, again I'd imagine that some are better than others. Is someone of you already using one of these? Anyone care to make a recommendation?
Would this be worthwhile?

Despite the big price tag, my N7000 has served me very well - its become an essential item. Although I have to carefully 'manage' it on a day to day basis (always having it charged to the max before I leave home - and having a back up battery with me), the greatest difficulty is when I leave home for an extended period. Ironically, this is also when I rely so much on the device also. With heavy usage, battery power just trickles away rapidly.
This its a question which I'm also interested in.
I found as I thought a good and not cheep battery on eBay but before purchasing I checked it in goggle and found android forum where people complain about this bataries. They looked under the sticker and the real battery power was something like 1500 mh instead of 5200.
So I deside not to risk with chip Chinese bataries.
If I had local store which sells bataries I would by. Thus I could change battery off it has fake marking.
Using standard browser with reversed colors can save battery life on amoled screen.
I used to this view and now some websites look even better.
I also tried some cpu tweaking tools.
Funny, today because of marketing companies put more unnecessary cores in the phones and than people install software to turn them off.
My experience with new batteries is not so great. Guess all companies make inflated claims. On the other hand I see significantly better battery performance on OMNIRom 4.4 atleast in standby mode. YMMV
I'm currently using an old LG Ally, and its age is getting to me. ARMv6 means developers are loathe to support it, 128mb of RAM is a tight fit, Froyo has its myriad limitations, there's no unofficial support for the phone anymore, etc. It was a good phone, for the price, but its heyday has passed, and I need more power for when I occasionally need entertainment whilst out and about.
So, after looking at the available choices (of which there are sadly few when a physical keyboard is a requirement), I'm thinking about grabbing a Droid 4 off a certain auction site, to replace my Ally. One major concern I have, though, is battery life; particularly while standing by. At the moment my Ally can easily standby with occasional usage nearly a week without needing a charge, with the following conditions true:
Gtalk and Checkin nonsense disabled
Auto-brightness customized to only provide needed brightness (e.g. not instantly blaring to 100% in normal lighting conditions)
Data connections off/voice only, GPS off most of the time
Minimal background apps
Of course, extended use of the screen or anything utilizing partial wakelocks tends to cut that time significantly, but time in-use compared to standing by, the phone spends far more time standing by.
So. Given the above usage and applicable settings, how long could I reasonably expect the Droid 4's battery to last? Would I actually be downgrading in terms of time between charges, like some of what I've read suggests?
Don't really know, over 24 hours, if running stock ROM or a modified stock with all unused apps disabled.
If I remember correct I got a several days, when I had forgotten it was on, but was not activated on a carrier.

Hmm. On the Ally, the primary power draw is the screen, with the awake cpu and wifi coming in second and third respectively. Are the main draws the same on the d4, or is the power inefficiency coming from somewhere else?
Just look at the specs
http://www.phonearena.com/phones/LG-Ally_id4498
http://www.phonearena.com/phones/Motorola-DROID-4_id6431
Specs Ally / Droid 4
Battery: 1500 mAh / 1785 mAh
Processor:Single core, 600 MHz, ARM11/Dual core, 1200 MHz, ARM Cortex-A9
Talk time: 7.50 hours / 12.50 hours
Stand-by time: 20.8 days / 8.5 days
---------- Post added at 10:55 PM ---------- Previous post was at 10:46 PM ----------
The power inefficiency is coming from the 4 times faster processor and only 15% more battery.
I wouldn't think it would make that profound of a difference, though; the CPU should be offline for the majority of the time when the device is idling with the screen off.
I'd also assume that the 4x faster processor wouldn't use 4x or more the power, even with two cores, considering it's both newer (advancements in general processing efficiency can be assumed) and on a smaller process (45nm vs 65nm).
It's looking more like a problem of how it's used, rather than the hardware itself (though the battery is, as you point out, piddly for the device specs it's running). I'm tempted to pick one up now just to see how long I can get it to last.
I'd noticed the official standby time that you quoted before I started the thread, though, and considering those times are generally greatly inflated...it's a little worrying.
First I would disable all know safe to remove bloatware see
Disabled app/bloatware list
There are 71 apps in the list, some may require rooting to remove/disable
or
try a modified stock rom like
[ROM]D4 stock De-Odexed JB 98.72.18
Wow, 71. That's an exceptional amount of garbage.
I probably would have gone and used CM 10/11 or a ROM based on them, is CM not stable enough to use over a stock derivative on this phone?
Cm does not get as good of battery life as stock jellybean
Sent from my DROIDX using Tapatalk
Ah, I see. Modified stock it is, then.
Guess I'll look into picking a d4 up to play with. Thank you for the information and your time.
if it helps you get a general idea (using the extended gold battery) i can probably get a day and a half of stand by time and i always have LTE enabled. this is using CM11. you can probably get 2 days or so if youre not using data but dont take my word for it. the screen has been the biggest battery hog for me and i keep my brightness at 10%~ most of the time. i highly recommend you look into an extended battery because the stock is pretty weak. the gold extended one is around 15 dollars while the mugen is 90~? dollars but mugens battery is way better with the only drawback being its massive size which can be a benefit to some people depending on how you plan to use the phone
I have everything "enabled". WiFi, Bluetooth, GPS, 4G. In short: My phone is running at maximum potential. With that being said... on Standby, it lasts about 24 hours. ~4 hours with the screen on and the phone actually being used.
You don't really notice it if you're like me and never use the damned thing, but I'd suggest grabbing an external battery, if you can. It's definitely an upgrade from the LG Ally. I used to have that phone, myself...
Thanks for the replies, guys. I've actually bought a D4 and am currently waiting while the seller takes their sweet time getting it into the mail. Pretty eager to get my hands on it, it's been a while since I've had some new (well, to me) tech to play with.

What ROM do you use?
The lack of screen-on time really doesn't surprise me...the whole TFT display/fairly quick processor/small battery combination and all, and the assorted radios take a fair chunk. Still, it doesn't bother me all that much, as I'm already used to the Ally's fairly mediocre screen-on life. Quite the contrary, really; if I can get the same life out of it at much greater performance levels, I'll be pretty satisfied.

Hmm, not terrible, but not especially good either considering the below. I have a few ideas to try for stretching the battery out, and am planning on trying both modified stock and various CM flavors, so we'll see.
Are you talking about this battery?
I was under the impression that any battery larger than stock would need a different backplate to fit (though to be quite honest, without handling the phone I haven't gotten much of an impression as to the various dimensions of it)...if that's not the case, I'll definitely look into grabbing the gold battery.
Just how much room is left with it installed? Is there still enough room to, say, slip an inductive charging receiver in there?

...how?
Maybe I'm just having one of those moments here, but the last I was aware of, there was a fairly consistent relationship between capacity and size/weight when it comes to li-ion batteries. I don't see how they could possibly be getting 50%+ more capacity out of the same footprint without utilizing recent advances in anode construction (unlikely) or using li-po and utilizing wasted space in the casing (not advertised as such, and a third or so of the casing being empty seems unlikely). nevermind, I thought the D4 was using a traditional plastic-encased li-ion.
I hate to call BS on something another member is apparently having some success with, but it doesn't seem possible :\
as stated by sd_shadow its the same size as the stock battery but keep in mind that the gold battery does not come with the sticky glue that holds it against the phone and in my case the backplate is fairly easy to come off and i dont think its very good for the battery to be hanging from the flex cable thats screwed into the phone.
the 99 dollar one by mugen power is way bigger and they provide the modified backplate with the battery so you dont have to worry about that unless you plan on getting clothes for your phone
if you get the official wireless charging backplate then you will not be able to use any clothes on your phone because its thicker than the stock one.
Ehh, problem being that I'm not really interested in spending another $100 for a battery on a phone that can be had for around $30-$40 used.
I'm hoping to work out some way to quickly swap batteries, so I can just carry a spare with me. I like to think I'm decently crafty, and I have way too much time on my hands these days, so...we'll see once I eventually get my hands on it.

I don't generally put anything on my phones anyway, aside from the mandatory Skinomi screen film. Regardless, what I had in mind was doing this, possibly reworked to add poppable connectors instead of hard-soldered connections.
Not really interested in overpaying for Motorola's monstrosity of a solution when there's a much more elegant option available.
there isnt really an easy way to have a backup battery on the droid 4 thats easy to swap unlike say droid 3 where you can easily pop the cover off and swap batteries. the battery on droid 4 is screwed in by 2 small screws and if you lose em your phone probably wont work until you get replacement screws
i had to make a battery change this weekend because i carry my stock battery along with the screw with me just in case and its honestly a pain unless youre in a well lit room with a table
your best bet might be to get a portable usb charger that would be usable for other devices as well. i have no experience with them but it seems a lot more comfortable than asking someone to hold a flashlight while you change the screws.
but keep in mind that if youre just listening to music you can expect the device to last about a day so needing another battery might not be for you

Wondering about that, actually. From what I've seen, all the screws do is press the ribbon cable down onto the ubiquitous springy interface pins, right? Plastic-encased batteries (like, for instance, my Ally's) provide the pressure with their weight and rigidity, rather than baffling design decisions like...well, a separate ribbon cable.
Though we don't have a particularly rigid battery to work with, it shouldn't be too hard to figure out a way to provide pressure to the pins without using screws. How solid is the battery door when it's locked in place?
I don't anticipate actually needing to be able to swap batteries on the go; after all, I thought I'd need to with the Ally but eventually tweaked it to standby properly - but figuring out if and how it can be done sounds like a fun exercise.
on a previous post i said that my back cover is fairly quick to slide off but i cant speak for others as my phone is from ebay. its supposed to be refurbished and the back cover was new but its still pretty bendable
the battery is held inside mainly by the glue and the screws. there is room for the battery to wiggle around if it doesnt have the glue which is what happens with the gold battery. if you remove the backplate and make the battery face the ground then its only gonna be held by the flex cable that doesnt stretch so its not something i advice. when i use the gold battery im very careful to never let this happen
the contact pins are held down by 2 screws and theyre covered by a small plastic piece thats pretty easy to remove by hand
if you think you can work something out than congrats but this is the biggest design flaw droid 4 has in my opinion

Yea, I saw that. I was referring more to its front-back/vertical strength, whether it could handle holding something against the battery pins.
Bendiness would be a problem, though.
Fortunately, what I have in mind shouldn't involve the back cover at all.

Reason I ask is, I've been looking into batteries for similarly-sized phones. The Optimus F5's battery dimensions look promising, and it's apparently either a 2150mAh or 2460mAh part (this comparison page says 2150 for OEM, but I can't seem to find such on ebay).
Both sets of dimensions are from "gold" battery listings, for consistency:
Droid 4: (7 x 4.8 x 0.4)cm / (2.76 x 1.89 x 0.16)" (L x W x H)
Optimus F5: (6.5 x 4.4 x 0.5)cm / (2.56 x 1.73 x 0.2)"
Slightly smaller, but 0.1cm/0.04" thicker. Is there enough room?
Playing Candy Crush for 22 hours straight can take its toll on your battery (and your marriage). Rate this thread to express how the LG V20's battery performs under heavy use. A higher rating indicates that it lasts a long time even when playing games, streaming video and audio, and doing other CPU-intensive activities.
Then, drop a comment if you have anything to add!
3 hours and 8-12 minutes of 1440p video at full brightness, loud speaker, wifi on, and screen recorder running (although the file messed up so i cant post it).
bad
Battle Bay: Less than 2 hours!
I can honestly say that it really depends on what I am doing. For example if I am digging around on the WOW companion Application or Yahoo's Fantasy Sports Application, the whole phone will get heated up and the battery starts taking a nosedive. If I'm not doing anything with my phone it can go 15 hours straight without losing a single percent. If I am just watching YouTube or something along those lines at 1080 or lower it seems to still go down, but not nearly as quickly as the (possibly poorly - from a power consumption view - designed) apps mentioned before.
As far as I'm concerned the removable battery negates any battery performance complaints. Out of power? Pop in a new battery, and you're 100% in a few minutes, back to endure more "heavy use"... How can any other modern flagship begin to compare?! (not to mention a year down the line, when I can just buy a fresh battery to mitigate deteriorating capacity, while the crowd has to buy a brand new iphone/s9/m10)
I've been playing Sky Force Reloaded a lot the past week. I had to be next to the power charger. I haven't bought a spare/secondary battery yet. I carry around a usb battery and a short cable when I need too...
Installed some more apps and games, and talk about nosedive. From the time I leave the house at 7AM to about 12 noon, the battery drops down to 15%(battery warning). I have to charge it then. I have to charge it again when I leave the office, which is around 5PM. Battery level varies at that time. Then charge again before bed. I still haven't rooted my phone. Phone temperature remains about 80F to about 108F(heavy use while charging) at times. LinkedIn, xfinity, Groupon, Weather, Waze, etc. Battery drainers! I've about almost had it. I miss root, and miss the ability to freeze apps. I will have to root this LG V20 sooner or later...

I have to charge it again when I leave the office, which is around 5PM. Battery level varies at that time. Then charge again before bed. I still haven't rooted my phone. Phone temperature remains about 80F to about 108F(heavy use while charging) at times. LinkedIn, xfinity, Groupon, Weather, Waze, etc. Battery drainers! I've about almost had it. I miss root, and miss the ability to freeze apps. I will have to root this LG V20 sooner or later...

Yes my does that too.. Battery lasts just a bit over half day. I purchased 2nd battery but it's getting very annoying to change and charge them when ur between places.
Hope he gets better

I usually can keep my phone charges, in the car, desk, night stand. Today we where doing Hurricane prep listening to Spotify while working, watching YouTube while in the car driving from place to place. Had to set the screen to auto brightness to deal with the BRIGHT sunlight outdoors. After about 3.5 to 4 hours of use and 1 hour and 30 minuts of screen on time I was down to about 38% battery. I had to drive home and grab my power bank. I've only had my V20 for 2 months.
Not impressed!

Stock AT&T H910.
Just got my new Note 8 and yesterday I had 7 hours and 44 minutes of on time and 3 hours and 10 minutes of screen on time and was at 50% battery. That far better than my 2 to 3 month old V20.

Can I ask if you are ok with where the fingerprint sensor is located seriously thinking about getting note 8 as well v20 screen on time is getting worse and worse everyday

It is a bit of a nuisance especially at first. I've learned to adjust my grip so I grab the phone a little higher up than I used to and this makes the fingerprint scanner easier to reach. Since the Note 8 as narrower than traditional phones due to the new display format going it higher is easier while still being able to hold the device securely.
Still not ideal but manageable and definitely not something that would keep me from buying the Note 8.
I'm also using the facial recognition feature in conjunction with the fingerprint scanner. It's not something I thought I'd be into, but it works really well even in conditions I assumed it would not, like low light and slightly of angle.. So if I don't feel like doing for the fingerprint scanner I can just got the power button while holding the Note 8 and it will unlock.
Note I do have slightly bigger hands than most.

As far as I'm concerned the removable battery negates any battery performance complaints. Out of power? Pop in a new battery, and you're 100% in a few minutes, back to endure more "heavy use"... How can any other modern flagship begin to compare?! (not to mention a year down the line, when I can just buy a fresh battery to mitigate deteriorating capacity, while the crowd has to buy a brand new iphone/s9/m10)

I disagree. If I have to change the battery every four hours of heavy (not even that heavy), somethings terribly wrong. If it was just one battery swap, maybe I could agree but I'd need at least 3 or 4. Luckily I'm usually able to keep my batter topped off most regular days. Removable batteries is no excuse to have horrid battery life.

Neat thing about a removable battery: it lets you swap out for a bigger unit.
I have a 6700 mAh battery in my H918, and haven't plugged in before bedtime in months. I can stream hours of video with full brightness and no thought for power. And that's the small option, the ZeroLemon unit is 10000 mAh, I just don't need that much.
In the end, the phone is only as smart as the user. I guess we can lead a horse to water.... but we can't keep removable batteries on the market if the people are too limited to use them :crying:

6700mAh battery, no thanks. I'm content with a normal size battery that can get me normal size battery life like other devices. Then a spare on those rear occasions I need it. The V20 should be commended for having a removable batter (probably the last higher end smart phone to offer one), but not it's battery performance.
I'm smart enough to want normal battery life out of a normal size battery, removable or not. :crying:
I voted "bad" because real world battery life is actually inferior to the 2012 Samsung Galaxy Note II it replaces. Naturally in lab tests the V20 massively outlasts the 2012 vintage Note II but I don't live in a lab. It's the only aspect of the phone that isn't a considerable improvement. I knew that if I listen to streams using the high quality audio with decent earphones the V20 isn't going to last like a modern Samsung or iPhone, or even Xiaomi, but I am a little surprised how it's not better. The replaceable battery is a necessity, not a luxury. Anyway it is mitigated by Quick Charge and the fact that the device seems to me to be just about beyond criticism in every other meaningful way.

Yes the battery life sucks stock but they do make a 4200mah now that fits in stock place no issues. I bought it and I get 6hours 44 minutes screen on. Much much better then the stock 3200 with no added size as it fits in stock compartment and cover.
Recommend to any V20 user.
I found myself seeking threads in these forums about different ROM's and SOT obtained. The results were way different between different users, some claim to get 2.5h SOT some 5h SOT under normal circumstances.
Under normal circumstances I never get more than 3h and I suspected that my worn battery (598 charge cycles according to "Charge Cycle Battery Stats" app) was far from the original 3000mAh.(Thats a manufacturer stat obtained in perfect conditions, real world must be around 2800mAh)
I needed to measure the capacity left in mAh,so I bought a USB ammeter power meter (Keweisi white digits, but you don't need it, I'll explain later).
Using the Power meter, to measure properly you need to avoid thermal loss and power loss when charging:
- Note 5 completely discharged at 1 or 2% battery left.
- Disconnect the Fast charge option in Android.
- From start to finish keep the note 5 Switched off.
- Use an USB low power charger, mine was charging at 0.8A
Results: 1800mah that's far from the 2800mAh(3000mAh) when new.
(Same test I'm getting 2200mAh out of the original 2800mAh on my old Galasy S5 Neo.)
You don't need USB ammeter, Android has a builtin ammeter calculator(estimation).
Today I depleted the battery (2% left) of my note 5 again (Rom based on Android 7.0) and under battery usage I added all the "Computed Power Usage" in mAh giving the next results:
mAh
557 Cell standby (I worked underground today)
333 Screen 2h53m (30% brightness and auto brightness on)
271 Device Idle
221 chrome
203 Android OS
43 Google Play Serv.
39 Androyd System
27 Youtube
20 Yahoo Mail
20 Wi fi
17 com.android.systemui
Total: 1751mAh
This result shows that the phone itself makes a good estimation of mAh juice available in you battery.
As an anecdote I run the same test that Jerryrigeverything in YT with his Note 5(6 month of use): Playing a 2k video in 100% brightness( auto brightness off) with sound and in Flight Mode(not even wifi). He gets 6h20m, I surprisingly get 6h. But those test are only worth to compare Note 5's
Conclusions(my own and humble): Surprising degradation of my battery, specially compared with the results obtained in my S5 Neo. According to "battery university" (a good scientific source of information about Lithium-Ion) I might have shorten the life of my battery abusing of the fast charge mode.

Same here, the problem is that is quiet impossible to find a genuine battery for replacement. All those on amazon and ebay are crap.

That's the next step, find a good provider and compare capacities.
What I know so far is that there's 2 different battery models:
EB-BN920ABE The most common, but most reviews complain about being 4 or 5 mm shorter, ...less volume less capacity.
EB-BN920ABA Difficult to find, It seems the original replacement according to this picture:
https://ae01.alicdn.com/kf/UTB8YQ_yanzIXKJkSafVq6yWgXXa0.jpg The original is the right side one.
I found a Canadian provider who seems serious (free of fantasy marketing) who also ships worldwide, it looks like the original, (or a extremely good copy) I'm going to take the risk and try it:
https://www.ebay.co.uk/itm/OEM-EB-BN920ABA-3000mAh-Replacement-Battery-for-Samsung-Galaxy-Note-5-N920-N920A/401346669803?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649
I'll post results in about 6 weeks....

How did it go? Those eBay batteries tend to be pretty bad in my experience.
Finally someone else is concerned about note 5 battery capacity, i replaced mine with an original one in feb 2018 from a nearby samsung service center for $40, i used Accubattery app to measure and compare the battery capacity of the old vs the new battery.
After two years of usage and fast charging enabled in all of charge sessions, the old battery was giving me 76% (2291 mAh) of the original capacity, while the new one is giving me 89% (2675 mAh) right now, the weird thing is that it was giving me 90% right when i purchased it, i dont know if this is normal or not.
As for SOT, the old battery was giving me 2.5 hours on average, with an average of 17 hours of total usage, the new one gives me 3.5 to 4 hours with an average of 20 hours of total usage (disconnect at 100% from charger and drained to 1% or 2%)
Hope you find this post helpful

I'm in the same boat as you. My battery life blows and I am looking for a decent replacement so I don't have to buy a new phone. How did that one work out for you?
