Best Battery - Motorola Droid 4

What would be the best extended battery to get for the Droid 4 (minus the Mugen)? I have found the following on eBay and looking for what your experiences are with them or others. I want the biggest I can get from the OEM that still fits in the original casing.
http://www.ebay.com/itm/171884738678 (2850mah)
http://www.ebay.com/itm/191617997652 (2600mah)
http://www.ebay.com/itm/131646087397 (2100mah)
http://www.ebay.com/itm/262314085580 (1925mah)

i had the gold one (first link) and it worked great but you should know that its not whatever capacity theyre advertising it as so i would say its better to just get the gold since its cheaper and it still gives about an hour more of screen time.
unfortunately all these batteries come without the adhesive that holds the battery in place meaning if you drop your phone the battery shakes and the flex cable snaps.
at least theyre not expensive right?

I think best battery is this mod - http://forum.xda-developers.com/photon-q-4g-lte/general/real-2600mah-battery-mod-t3308399/
In droid 4 and photon q is the same battery.

The biggest from the OEM is 1745mAh (or roundabouts that, don't quote me on it...); that is to say, the one that came with your phone.
The ones you've listed are almost certainly fakes. Most of the time they're actually either
A: OEM batteries - easy to tell because the cell itself is marked with the real capacity and model # - that have had the original sticker removed and a new sticker put on them (the gold ones are pretty well known for this)...
or
B: Unmarked, potentially hazardous Chinese-made mystery batteries. Key thing here: unmarked. You can bet good money that if some manufacturer had managed to get 50% more capacity out of a Li-poly battery in the same footprint, they would be plastering their name all over it, not letting some small-fry eBay seller peddle it at minimal price. No markings from a well-known manufacturer = big, glowing-neon-red flag.
Progress in battery technology being stagnant as it has been for a while now, if you want a bigger battery, your choices are to get a huge "official" battery (Mugen's ridiculously-priced monstrosity), or try to trim the plastic around the battery cavity and squeeze a slightly bigger battery from another phone in, as shown in the post above.
We don't have all that much extra room around the battery in our phone, though, so be careful. Note where the cover hooks on and don't cut past there.
Alternatively, get a good power bank and plug it into that every now and then. Xiaomi's 5000mAh offering is small (roughly the same size as our phone, in fact), light, and cheap at ~$13 (Gearbest). Even comes with a short cable, so you can plug'em together and toss'em in your backpack for a bit.

Extended Battery Opinions Requested

I've been looking at the xv6800 extended battery options. Since I came from an 6700 with the monster extended battery, I'm kind of leaning towards one that is somewhere in the middle. The monster 3200 (or 33, 34... don't remember) was awesome, I don't think I need that much day to day.
I don't think the 1800 is an option, so I guess I have to choose from the ones that require a different battery door. I'm looking for the minimum increase to phone thickness.
Option 1: I can't find measurements, but this looks like the least additional thickness. 2400 Mah. I can't get a good indication on the thickness it adds.
Option 2: This is interesting due to the way it is designed, it looks like it might feel comfy in the hand... 2200 Mah
Option 3: This is pretty much the same, but squares off the back so it might lay on the desk, counter, dashboard, etc more evenly... Another 2400 mah. At that point, I might as well get the monster 3200 Mah
I'm leaning towards option 1 since it is close to double the capacity, but it looks realitively thin.
Thoughts? Opinions?
seidio makes the 3200 one but no case for it.

Yes, I was aware of that, thanks. I'm just wondering if anyone has opinions or reviews of Option 1?
option 1 adds about 1/4 inch
Option 1s picture could be deceiving since the picture makes it hard to tell how thick it is from the side. The monster battery is overkill for me. I would go with option 1 if it extends only half way out as much as the monster battery would. It would be nice if somehow I can get the option 1 battery with the option 2 battery cover.
Option 1 battery with option 2 cover.
I have the option 2 Battery with a slightly different cover...Sort of Slanted sides to a flat and the cover looks great...
But don't bother with 2200 or 2400...
Mine is 2200 and you really don't get a lot extra from it. Can't imagine an extra 200 is going to make a significant difference. You will wake up the next day with a usable unit but you won't make it through the day.
Go for the 3200 if you can get it.
That should let you skip a day on the charging if you have to...
It would be really nice to see these batteries + covers from many different angles. People willing to take some pictures and post them?
It's a battery and cover for a phone. I think if you're worried about "looks" rather than functionality, perhaps the priorities are a bit skewed.
Buy the biggest battery for your needs, the looks are going to be what they are regardless because the manufacturers decide what the thing looks like. If it's ugly, to you, return it.

I don't agree with your comment completely. Yes, looks is a comparison option, and based on that alone, I wouldn't get the 3200, but I know that I will require x minimum amount of battery, so that is not the only consideration. Some of those with the slanted covers appear that they might feel more comfortable from a grip standpoint. The 3200 might be too big as it relates to holsters, pouches, etc. I am asking for opinions across the board, not just a beauty contest
Based on Asphyx reply, I might just go ahead and get a 3x00 variant... probably the prettiest one
I have the seidio battery and extended battery hard cover, it has a rubber"y" grippy feeling to it. Looks fine and all in black. My holster fits just fine.
Not sure what beauty part of a phone has to do with it, you could have a really beautiful dead phone, but well, it's just a really beautiful brick then.
Thanks,
Has anyone found a charging base that works with a phone (6800) that has the extended battery installed? I don't want to unplug the battery to charge it and I'm trying to get away for the cable bit, I liked the base that the 6700 had.
I've done EXTENSIVE looking for this exact thing, and so far have had to mod 2 normal cradles so I can use them with a super extended battery.
The cradles because they had to be modded didn't have anything to support the device standing up, finally gave up and just use the cable on the desktop.

Here are a couple of options for you.
http://www.seidioonline.com/index.asp?PageAction=VIEWPROD&ProdID=832
http://www.seidioonline.com/index.asp?PageAction=VIEWPROD&ProdID=833
The standard dock has a 3.5mm audio port that allows you to plug into external speakers, while the Jr. version is simple sync & charge. Both will work with extended batteries.

NEITHER one of these answers the original request. The only difference between these two cradles is that one lets you keep the rubberized case on the device while charging. That is NOT the same as charging while having the extended battery IN the device using a cradle. I too would like this option. I've asked for this months ago. I have a super extended battery with a rubberized case and want a cradle that accommodates that and a spare battery to charge from the cradle as well.
To date, nothing like this exists.

HTC Touch battery on deal extreme

can the one they are selling on dealextreme be used for our p6900's? i know that one is for p3450 or something.. but will the back cover fit? someone wrote there that the battery does work on our phones but the cover doesnt fit properly and he had to cut it to fit? anyone else on this board has tried this option yet or is everyone spending over $50 for battery?
I looked at the one on dealextreme along with about 20 other web sites. I finally decided on a 2400 mAh battery by mugen power. I paid 69 US for it and shipping was free at nakedcellphone.net
When it finally arrived I was absolutely impressed for the following reasons:
the capacity of the battery is more than twice as long as the OEM bat;
the back cover is thicker than the oem cover but does not have the hump;
although thicker, it actually fits in my hand more comfortably. I like the way the phone feels much better;
the chrome ring around the camera lens looks identical to the original, and as one would expect the diameter at the outside is larger to avoid an optic tunnel;
color matching is identical to the Sprint Vogue.
This phone rocks!
yea the only problem i had with the dealextreme one was the back cover.. the battery is amazing.. lasts me forever.. but the back cover is quite ugly and doesn't fit the vogue properly.. it leaves a lil gap at the bottom.. i think its designed for the GSM version .. but the battery itself is amazing.. just incase u wanna buy it just for the battery...

I looked at naked cellphone on ebay and was interested in the cradle they offer and possibly 2 extended batteries (i'd put the OEM away for a last ditch backup) but does the extended batter fit in a cradle properly with the larger battery installed? Any success here?
Thanks

MNN -
Sorry for the delayed response. No, the extended battery will not fit into the majority of cradles out there. But when I googled close to 50 different web sites selling accessories for the vogue, I stumbled across 1 or 2 who were advertising that they had cradles that would fit the thicker phones with ext bats. Sorry I don't have a site to give you but you should be able to find it if you haven't already.
Update to the Mugen Power 2400 extended battery:
It has awesome battery life, like a week or more on standby. I can get hours and hours of of GPS, phone use, mp3, web, etc. at least 8 hours or more. I love the phone.

Does the battery work well now?
Does anyone know dinodirect.com?
This site is also selling HTC replacement batteries. To guarantee your phone life span, I would recommend you to use original battery.
SKU: A0324000KD
This replacement can be applied to 6900.
I ordered HTC Touch battery from dealextreme, but i never received my order so far.. So i reordered it from Chinabuye, an online store from China. I received ontime with free ship cost. Through paypal, payment i made easily and find its safe with them. When it comes to quality, its good one and brand sytlish. Rates are quite cheaper and has discount features.
Chinabuye !
I think it will better to use online Shop from China Chinabuye rather than dealextreme !
Chinabuye has more payment options and free shipping option ! which make buyer attractive to buy ! and also it has great quality products !
The battery and cover I just purchased today are these:
http://www.batteries4less.com/htc/v...v6900-vogue-oem-bte6900-extended-battery.html
http://cgi.ebay.com/BLACK-BACK-DOOR...662959?pt=PDA_Accessories&hash=item45ebf8516f
Looks like a really good price on the battery and I'm crossing my fingers that they cover will fit - looks like it should.
Good luck on finding the battery. These Vogues are all coming up on end of life for the batteries it seems as they can only be charged so many times.

3500mAh for Defy

DealExtreme now have a 3500 mAh battery with cover Link
However I don't think it's 3500 mAh and the quality is probably low and it wont be water resitance because it miss the extra internal cover for the battery.
there is such topic already, and this battery is the same, that already more than month selling on ebay
It's thicker than stock. I have ordered one similar to that as well. Just waiting on it to arrive. There is another topic here that is already about extended batteries for the defy. Your link does include the rear battery cover. However, I would not try and dip that in water unless you put some kind of waterproofing on the replacement back cover. Getting better battery life for cheap does have its disadvantages as well. Unless some company makes one that retains water resistance with a large battery and replacement back cover.

Oh it exist a topic like that already. I missed the "Extended Battery Idea" topic ._.
Anyway Dealextreme is a more know seller then ebay sellers so I would go for Dealextreme insted of ebay.
agree, i might consider the larger battery
This is really interesting! I want one too but if any of you were to buy it, i would be cautious since dealxtreme is known for having cheap chinese made products, theres an american company i found online that sells this battery: http://www.wirelessground.com/motorola-defy-extended-high-capacity-battery.html just sayin
Another dealextreme 3500mAh
Now there's also this one:
dealextreme.com/p/3500mah-rechargeable-extended-battery-pack-cover-for-motorola-mb525-73564 - 3500mAh Rechargeable Extended Battery Pack + Cover for Motorola MB525
In addition to the previous
dealextreme.com/p/replacement-3-7v-3500mah-battery-pack-with-back-case-for-motorola-defy-me525-mb525-bf5x-90589 - Replacement 3.7V/3500mAh Battery Pack with Back Case for Motorola Defy ME525/MB525/BF5X
Both back cases have no waterproofing. As (remaining) capacity is probably more related to age of the battery than to price; I would pick the newer white one. Anyway, you only loose $11 instead of ~$30 for the ebay options.
I just got a D.Seven extended battery for US$13
Its more than double the thickness of a normal battery, comes with an extra cover which makes you lose the waterproofness....and my shell doesnt fit now, the phone is now damn bulky...
Dont think i'll be using it anytime soon, unless going camping or something
Iit would have created a smaller battery

Hi.
And what about the battery life ? Huge improvement ? Or insignificant ? Thx for the test.
It would be so uncomfortable to carry it after using this battery.
so....is it works?
at least should have double time usage with this battery....
... right?
I tested my D.Seven 3000ma battery....battery life increased by 20 - 30% only...

Extended batteries (3500mah in this case)

Well... so far I've ordered a 3500mah extended battery from Hong Kong.. but as I believe this will take rather a long time to get here... I've ordered another one from the UK as well from ECELL, which apparently has a silver extended cover.
I'm well aware that these are likely cack batteries and I have a plan for that
Basically I'm hoping that whichever one I consider to be the worst will either die on me... or I will simply end it's life prematurely. I am going to cut open the battery (Carefully!) and try to replace the cell's with two Genuine OEM 1500 mah batteries, for a true 3000mah. I bit elaborate but I think it should be possible as long as I cut in the right places.
EDIT: I found genuine LG batteries for about £8.50 each plus about £5 postage, so will order 2 batteries for around £22. They are special order though, so will take 14-28 days. (I am also getting them to confirm the capacity is defo 1500mah, as no point buying them otherwise.)
Update: Images in post #29 : http://forum.xda-developers.com/showpost.php?p=23120430&postcount=29
Well.. I was getting a little impatient... so when I was really tired (and may just a little to drink), I ordered one from ECELL on ebay. It had a silver cover and a 3600mah battery (We all know it isn't that much), and was listed for the 2x P990. Turns up.. it's for the LG Optimus S :-( Bummer. Just trying to get a return/refund.
So... experiment is delayed somewhat.
Update: Two LG OEM batteries have been ordered ; The incorrect extended battery sent back ; Still awaiting the HK Extended battery. Bizarrely I thought I actually ordered a 2nd UK based battery.. but I was so tired I think I forgot to do it lol. Can't wait to have a play with these
Refund form ECELL given without issue Have now received the 3500mah battery, and just running that to see how thing's are with it. I am waiting on the two OEM batteries to turn up from LG before I can start modding this extended battery.
Since I also have a bigger case now, I am going to look to see if I can play around with an external antenna as well.. and maybe fit a bigger antenna inside the expanded case. With that in mind I have ordered two antenna's of different types to see which one fits (expensive.. but then at least we all know )
Sounds really interesting.. keep us updated please!

i got the 2400Mah battery(2 days of usage) i'm looking forward for you're results
specially the modded one pictures will also be great if u can.
thanks!
Apparently the LG batteries have been dispatched now, so should get them within a few days. Only annoying thing is that even LG were unable to confirm whether these batteries I'm getting are 1500mah. I will be gutted if they are not lol.
btw.. you should see my desk at present at home. I have about 5 phones, four of them in bits awaiting tinkering, LED bike lights (all modified), circuit boards from laptops everywhere, reparing a 4x 18650 battery pack + routers etc lol. And I just realised that I actually don't know where my soldering iron is ROFL. Must dig one out.
Anyway... I'm looking forward to it and if I can get it working, I'll put up pics etc. I'm very interested in trying to get the temp sensor working (although I realise it may only work for one of the batteries.).
P.s. as for extended cases and covers I bought this w w w.ebay.co.uk/itm/Clear-Black-Trim-Rubber-Case-Cover-LCD-Film-Pro-LG-Optimus-2X-G2X-/180782656771?pt=UK_MobilePhones_MobilePhonesCasesP ouches&hash=item2a177c6d03 and then cut out the back clear part. It's not a perfect fit, but it will work for the moment (Buy at your own risk.. I actually stretched mine too much when getting the clear part out).
Genuine LG batteries have just arrived about 30 seconds ago. They are 1500mah
So with the delivery charge added in they were £11.04 each (£8.49 each without delivery charge). So if you ordered more it would be less due to the one time delivery charge of £5.10. Not bad for a 1500mah genuine battery! Batteries dated 10/09/2011.

Yes. I've now ordered a second "3500" mah battery so I have a spare cover and shell in case I **** anything up. I am just trying to gauge the capacity of the 3500 battery. On my first run it lastest almost 2 days on stock rom, with a fair amount of use. I would prob say only around 2000mah at a guess though.
I'm just trying to get it to run down again for a 2nd charge now.
Once all that's done, I'll open it up and start tinkering I will have to get both the LG batteries to the same state of charge as well (same voltage level) before hooking them up.)
Bear in mind I've spent £22 on original batteries that I am about to hack open for the cells inside, so there is no going back lol. Pretty expensive mistake if I **** it up relatively speaking.

no doubt it could be an expensive mistake, but if u succeed which i think you will the results will be probably a 4 day battery. so i think its worth it
i got the 2450Mah battery and it holds about 2 days with medium usage, so im really thrilled about ure test as i dont care about the size of the phone,
if you can share pictures it will be great you can also p.m if u want!!
thanks.
Shpapy.
No problem, will do
I charged the battery again last night, and rapid drained it running bluetooth (nothing connected), some GPS usage and wifi with smartshare running a video across from my NAS drive. In the morning it was down to about 25 percent so tried GPS on cycle to work and then drained it with music and GPS until 1%. Charged it without using it, and it's reporting about 1900mah estimated for the battery. I don't rate the estimator as highly accurate btw, but it's a guide .
I will try to take the battery apart tonight if I can. Not sure on best way to open it though, as I will need to reuse the carcass.
Damn.. was taking it apart and fried the circuit it came with. Unfortunately the metal legs that bring power from either side slipped off and touch the outer shell of the battery, was enough for a small yellow spark :-( oh well. (EDIT: Hmm.. circuit may still be alive actually...)
It's two batteries pressed together with several layers of thin plastic between them, either for insulation, spacing or both. I'm actually pretty surprised the cells weren't isolated better from each other.
Update 1: Well, for the first time.. I just managed to burn myself with electricity opps. These packs are really badly isolated. Shorted it on the tip of my finger... beginning to hurt lol. There are NO ratings on these batteries whatsoever. However, one thing they are is... amazingly well balanced. Just measured them and they are both exactly 3.78V's.
Update 2: The circuit and LG Battery will NOT fit directly into the old casing. There will need to either a mod to the extended casing, or we'll just have to 'go without', and make a casing up. It's looking like it's best to do without using the old battery at all actually, and just wire the two batteries together using the LG circuitry. (Well only one of the circuits).
Update 3: Will dig out the soldering iron tonight and get this double battery running
Update 4: Have VERY BADLY soldered the batteries together and combined battery is now charging in the phone. Due to the excess solder on the sides the battery is not quite proper fit, so I will have to redo it at some point. Really very dissappointed with how awful the soldering is, I will simply HAVE to redo it once this experiment is tested. Any tips on a soldering iron chaps? On the plus side, the one thing I do get is a temperature reading :-D
Tip number 1: Quickly snip the circuit off first and DO NOT let it touch the side of the battery casing, it will short out.
TIp number 2: h t t p://www.technfun.com/pages/article.php?id=22 Excellent guide. Take note of the safety tip!!!!
Points of interest
A) The extended battery is EXACTLY double the width of an LG battery.
B) LG OEM Batteries are made by Sanyo
C) Don't use a conventional soldering iron... it is almost impossible to solder the negative side and you will end up overheating the battery if you are not careful. (Any tips here guys?)
Charge battery up last night, and stayed up wayy too late trying to drain it.
Technique... used the 'flashlight' app to keep the LED on, turned on bluetooth, turned on wifi, and use smartshare to stream a movie (at full screen brightness) to the phone. Played Dungeon Defenders for a while as well at full brighness so hopefully the graphics core would take more power. Battery Temp got as high as 40C under 1400mah draw. Odd thing was that battery widget pro at times reported +25000 Mah(ish), yes PLUS '+', and 25000mah, that's just insane..not sure where it was getting the figures from :-(
7% battery left when I put it down, voltage was 3.550 or very close. This morning, voltage it still had 7% left and voltage had increased to 3.7 ish. Guessing it's because the battery was warm last night when under heavy strain, and now it's relaxed and cooled it's feeling better lol. (Or maybe something else?)
Running gps client down now in attempt to drain the rest before recharging. Ideally want to get it down to 1% before a full charge.

7% battery left when I put it down, voltage was 3.550 or very close. This morning, voltage it still had 7% left and voltage had increased to 3.7 ish. Guessing it's because the battery was warm last night when under heavy strain, and now it's relaxed and cooled it's feeling better lol. (Or maybe something else?)
Running gps client down now in attempt to drain the rest before recharging. Ideally want to get it down to 1% before a full charge.

cool progress , can we get some pictures of the new battery?
how were u able to fit it in? i get u got a bigger case but still....
share with us ure images / knowledge its sounds really cool doing.
I basically copied what they had done on the 3500mah battery, and merely connected up the positive to positive and negative to negative terminals of the batteries using thin strips of metal, and only used one circuit from the LG battery. Basically I parallel the batteries to increase capacity.
I used a small spacer to keep the batteries seperated, but thinking about it, I could have use the bodies themselves as the 'negative' but it wouldn't have been a good connection). I then just taped the battery up and use the 3500mah battery sticker to hold it all together.
This really is just a 'prove it works' / prototype, and I will remake it neater, although I may have to buy a better soldering iron.
Pics later.
Note: After charging back up from 1% this morning to 100%, the 'estimated' mah by Battery Widget Pro is 1551mah. This would indicate to me that one battery is not connected properly unfortunately. I'm gonna run the battery and see how long it lasts under general usage. If it lasts only a day and a half, then I suspect I will have to resolder.
I bought a 3500mah half a year back and it wasn't any good. Twice the width but lasts the same as the original one. It'll be good if you could show us some pictures? I may consider making one too!
To be fair the estimated capacity of the 3500mah was around 1800 to 2000 mah. Pretty good considering it came with an extended back cover for under £5. It does seem entirely random though, and I was never comfortable without a temperature sensor.
The work I have done so far is rubbish to be honest. I thought I'd make a better job of soldering. I will have to redo it, as the fit is terrible due to the solder being too big/messy, and the connections are not very or or not working/broken.
Can't wait to see the results.

For some reason, battery widget pro was recording very high mah draw/drain. I do not believe I soldered the negative terminals well enough. I took it apart and tried to prise a little flap of metal up for soldering, and managed to rip the terminal off the pack. I will do my best to remedy this of course and let you chaps know the result.
I also have the 3500 mAH and I was wondering if it was really giving 3500 mAH. I'm getting about 1.5 days on this battery with moderate usage. Heavy usage I get about a day. I wonder what I'm doing wrong. I think it's supposed to last longer.

[Q] When is Zerolemon extended battery for Samsung Galaxy S 4 Active coming out?

I would like to know When is Zerolemon extended battery for Samsung Galaxy S 4 Active coming out?
Never. That would require a new battery cover which is very accurately designed with it's o-ring to seal out water from Samsung. Do you want to trust a $600 device to a cheap 3rd party cover designed by some wanna-be engineer that it's going to hold 30 minutes at 1 meter?

Probably never. This isn't a dumb question like the guy above made it seem. They would just release a battery with a case that would devoid the protection that the device receives from the back cover. Which still wouldn't be too bad, considering you'd still have the shock proof, dust proof, and "water resistant" front (I say that, because now the back isn't). It also probably won't ever come out, because very seldom few people like you and I would like a huge battery for the Active, as the only way to do that would really be to lose water proof capabilities. Which is the main reason why people got the phone. So, it's just not a money maker if they did. They might sell ten or maybe even 100, but not enough to spend the money to develop it and produce it.
One of the other advantages of the S4Active is that it has a removable battery. What I do is, I have a second battery which I bought along with a charging pack that charges the battery independent of the phone. It was the best investment I've made in regards to phone accessories so far.
This way, I always have a second battery that I can carry around with me (in a secure little case) without sacrificing the size/aesthetic of the phone (since I can put that spare in another pocket, leave it in the car, etc) and I don't have to worry about the water proof seal. In addition to this, I'll use the MHL port a LOT less, which means I'm far less likely to damage it (or it's flimsy water-proof cover).

I think I'll follow the suggestion of having a separate battery charge and an extra battery pack.
