hi all,
I've just bought a 2nd-hand XDA iis and is battery is not so good.
So I intend to buy a new one.
But I'm wondering which bat is the best now.
I've gone to ebay and see that they have some types: original 1500 mAh, 2400mAh, "slim" 3200 mAh and "fat" 3600mAh.
I think the 3600mAh is the most suited for my xda.
Is there any better choice? Where could I buy it?
With the 3600mAh, how long would the xda would last if I use wifi IE with the lowest backlight?
Do any of you have any problems with it?
Could I use my old charger or Do I have to buy a bigger one?
Could I still use my usb-cable (not cradle) for charging my xda?
And is there any conflict with WM5? (I've just read in our forum that someone have problems with WM6).
Thank all of you so much.

I would say that primarly it would depend on if a 'fatter' and heavier phone bothers you.
Keep in mind that just about all the cases and various accessories that hold or clip on to the phone are designed for a phone that has the original battery, so a thicker battery may well make them unusable (cases are the primary example I would give).
How long it would last is impossible to say, as it depends on how you use the phone, what apps are on the phone, and so on. Also, 3rd party battery quality does vary. Which manufacture is the best, I can't say as I've never seen any place that reviews battery life.
I've never heard of any incompatibilities when talking about a particular version of win mobile and a certain capacity battery, and can't imagine that it's even possible.
Pick one and see what you get, then post the results here so the every one else can benefit from your experience.

At last, I've bought a fat 3600 battery and I think it's a good decision.
Now, I can use my fone for browse Internet in near 6 hour with wifi; or I could use it with 5 day stanby (how amazing).
some small problems are:
- the fone is thicker and heavier (no problem with me).
- My third party charger is a bit hotter.
- And the charging time is longer (ofcourse).
do not by batteries by ACME power. I have bought 2400mAh and feel no difference compare to standard old battery. Besides, I have troubles with bt. it turns off by its self with only this battery.
I bought a battery for my Htc Harrier about 4-5 months ago. Sorry i dont know the brand of it but its says its 3200mah and "replacement for XDAIII". The inside of the battery is kind of bloated out from the heat and looks a little dodgy but still works. Ive had a few problems with it where it powers off for no reason. When i turn it on again the battery charge looks fine.
Just a couple of days ago for the first time my phone just completely hard resetted and lost all my data. I again turned it on and the battery charge was fine. im blaming that on my battery.
I use my phone mainly for listening to music on my bluetooth headphones while im driving to school and for typing things out on my bluetooth keyboard at school. The standared battery that comes with the phone simply has not enough charge time to do all this.
With all its annoying problems i still use my battery. I just make sure i back up my most important things on my storage card. And charge it every night.
Soon im going to buy a HTC Blue Angel due to my countrys crappy plans that the Harrier comes with. Maybe i might buy the 3600mah while im at it.
So my advice is if you dont need the charge of a extended battery then stay away. Unless you are like me and need the extra battery power then beware of some stress ahead that it might give you.
I'm hoping for feedback or observations on the nooks battery compartment. In particular, what are the possibilities of installing a larger capacity battery? The teardown pics have provided good info, but I was wondering if anyone who has opened their baby up has noted any....extra space. The current battery is okay but you can never have to much power! : )

As with any device of this type, you'd definitely have some hefty constraints to work within.. Most notably, the thinness of the battery. It wouldn't be impossible to rig up a different battery, but you'd most likely not be able to fit one that lets you put the case back together properly.
In my opinion, it's probably not worth the effort. If you want some more battery life, get one of those rechargeable Duracell battery packs with micro-USB connector. They're like $35 at Wal Mart. I got one to use with my Atrix if I'm away from a charger for an extended period of time.
you could always try a solar powered recharger

Seriously?? The NC gets 12 hours of runtime in full active use, and in standby it'll run almost forever (unless you have some widgets trying to stuff all the time even though wifi is off, HELLO WEATHERBUG)...
Do you really need more? More runtime, more WEIGHT?
When I got my 1st pc it had 512k of ram and a 10 Megabyte hardrive, freinds exclaimed: "damn you'll never use that much memory!" Well I did use all that memory and soon wished I had more. Hell yeah I'm serious about more power! What with running slingplayer, some serious web surfing, and a few rounds of heavy flash gaming, the Nooks current battery is..wanting. Sure the battery is fine for an email or two and maybe a few wikapedia searches, its more than most grandmas could ever want or dream of; but with current rom development running rampant the nooks abilities and uses are expanding. I'm not sure what is possible, I'm looking for observations pertaining to the interior dimensions of the nook. I remember seeing a reference (I don't think it was xda, it might of been along with one of the early tear down pick articles) where someone mentioned that there seemed to be enough interior space for some type of battery mod but there were no details. l will eventually pop it open and dig around myself but was hoping someone might have info to share.

Thanks for your reply. I 'm sure you will turn out to be right about the interior space constraints, its what my own gut feel contends. I did do some research on larger battery packs using tear down info and was surprised to find a wide range of battery capacities and volumetric formats for very modest prices. Given the nooks intended design, B&N would have sound economic reason not to pack the case with more battery than needed. We have a phone processor and larger screen, it is possible that the cases design is sized more for "look and feel" than mimimum volume. By the way how do you like the Atrix, dual core is very sexy, is it meeting your expectations?

I believe the only thing thay kept them from adding more battery was weight. I think its current weight is at the heaviest it should be for an ereader. Im currently very pleased with my battery life. Combined standby/use time is well over 8 hours.

I guess it is "possible", but it will mean cutting out the metal backframe to add room for the battery. I don't mind modding things, but that might be a bit much should you ever want to hope for service...
please correct me if I'm wrong, but isn't the nook color put together in such a fasion that once it's taken apart there is no way of putting it back together. I seem to remember there being people who's bezel came lose, and were required to do a return.

Since they went out of their way to use a special uUSB connector for charging I wonder if an external battery pack would be able to supply enough power while the NC is on to, at least, supply the normal usage. Anyone know what the current draw is when the NC is on?

My NC ranges between 8% and 10%/hr usage, so that's 320mAh to 400mAh on low brightness, wifi on and semi-active, and reasonable stuff going on (not heavy gaming).

If the power source had a standard USB outlet, you could use the OE B&N cable. Most likely an external power source wouldn't have the 500 mA restriction on it's USB ports; one would have to verify of course.

Looking at the picks do you think the battery pack could be doubled up? I wouldn't rule out a some dremel work to get 2x the battery life, if the external case could remain sound. From the picks it seems there might be space where the back case curves out. It's difficult to tell the depth of the curve relative to internal components, or if any real usable space is there. I'm kinda hoping to hear from someone who has popped the case.

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 ?

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!
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

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?

Just how much room is left with it installed? Is there still enough room to, say, slip an inductive charging receiver in there?

That battery is same physical size as stock, just rated higher.

...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.

How much vertical wiggle space are we talking about here?
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?
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):

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.
How to calibrate battery after replacement or when needed here.
I replaced my battery recently, they told me that it's not the original one, its a Chinese made but works well. So far, no issue.
Where did you get that one?

From Ebay. Bought it from a trusted seller.
Sorry for the late reply, i wasn't around for long.
Thanks. When possible, please pm me the sellers info.
Gonna buy one asap

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.

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
https://m.aliexpress.com/s/item/32572840069.html#autostay
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.
