extended batteries

Speaking as someone who uses their phone pretty darn constantly, I'm in need of a battery that lasts a bit longer than the stock.
currently, Seidio is selling an extended battery (I would link, but as a noob I'm not able to..) 1750 mAh - no new door required, but only a gain of 450 mAh..
Verizon has stated there's a 2150 mAh extended battery coming, but that will almost certainly require a new back plate.
Anyone spotted any other compatible batteries yet?

I ordered the Seidio one and while it fits behind the stock cover it also adds a bit of weight, which is great considering how light this bad boy is.

Seidio is also going to release a 3500 mAh battery in the near future! According to their website, it adds 3-5 mm of width. But for the extra battery I think it will be worth it. The only problem is I am debating on purchasing this because I had one for my tilt and well it flat out sucked after a month of use.

what do you mean it flat out sucked after a month, the thickness or the capacity of the battery?

The battery itself would barley last a day if I was lucky. Seidio just said it needed to charge like 8 times before it was full. It didn't kick in. Is this rare?

Did you let it fully drain till the phone died, and keep turning the phone on until it wont turn on anymore. Then charge it fully, unplug when it is fully charged, let it get back down to 90-95%, then fully charge again, let die & repeat. Do that a few times and your battery life should be better. This is what I do whenever I get a new phone...

We use LiION Batteries, No special charging required
OK, to start, there is NO NEED to do any special charging conditions with Li Ion batteries, it does not matter how they are charged. A standard battery will have between 400 and 1200 charge cycles before it loses 50% of its capacity (1200 if you charge at 50%, 400 if you charge at 0-10%, like when the phone quits on you). Ni Cadmium on the other hand does require special charging situations but we don't use them in cell phones because of the mass. You can do take the advice of the previous post, but if you do that I would suggest sacrificing a virgin symbian phone or doing a handstand while plugging in your phone to charge. That might increase the battery life too.
Secondly, I spoke with Verizon, and their 2100 mA extended battery will be available soon and it is supposed to fit with the stock backing, probably the best way to go if you ask me, only $60 too. I am checking their site almost daily waiting for this to become available since like many, I need more battery life, I find that I can barely make it through the day without being conservative with the use, and that's on a work day when I'm not on it that much, on the weekends I have to charge it in the afternoon.
If you want to save on battery, turn down the screen brightness, chose a background with as few colors as possible, the more black the less battery you will use since its an AMOLED, blacks mean there is no power being used on the screen. Turn off your GEO locations services both on the phone settings and in programs that run a lot. This will easily save you 25-30% battery life.

I was at a Verizon store yesterday asking about it and they showed me their documentation. Their extended battery will come with a new back cover that is slightly raised to fit the larger battery.
I'm waiting for this too because it looks like it will be the most aesthetically pleasing option.
Too bad the guy had NO idea when the accessories were going to become available. Ugh.

Verizon doesn't trust their employees very much - to prevent leaks, they don't tell people about equipment/accessory release dates til within about two weeks of the actual release. The Incredible launch announcement had one of the longest announcement to release times I've seen the the last two years.

$14.99 + free shipping for a battery that lasts all day from moderate use? This sounds great and I'm ready to buy it now! ... But is it safe to use this battery with an Incredible?

I dont know, but my seideco 1750 def gets me 3 more hours a day on my Incredible. I have switched back and forth from stock and the extended...the extended wins EVERYTIME...so Im not sure about that report.

@ suzook
I read that my OEM TP2 rated as one of the best.
TP2 OEM standard issue Rated @ 1500mAh Tested @ 1414mAh
Most Likely our stock incredible battery has a lower mAh then it actually states it is.
@ Xxq TZ pxX
Yes it will work because its in my phone now working like a champ ;O)
I also told someone else here like myself who swapped from the tp2 ====> incredible and he seen it first hand as-well.

TP2 batteries work fine
Hey all,
The TP2 battery works fine. Same size and 200mAh more than stock... in fact I've seen them sold on Fommy.com as the thin extended battery for $44.95. Don't be fooled, and just go buy the TP2 batteries. They're cheaper if you don't need the therapy session of a rebranding.
Enjoy!
P.S. Got a workaround for Skype too...

I'm sure a number of HTC CDMA phones have interchangeable batteries.
I swapped out the 1500mAh battery from my Sprint Hero and put it into my Incredible. It's easily out lasting the stock incredible battery.

I ordered the 1500 HTC battery as well. Between those to staying charged I am not worried about it.
Also anyone know of a battery charger for these types of batteries?

For those of you that want a red 1500mah battery I found this but im not sure if its oem or not it just says its an htc extra capacity battery hxxp://shop.htcpedia.com/index.php?dispatch=products.view&product_id=825

[Q] 2430mAh Battery

Has anyone tried this GOLD 2430MAH BUSINESS BATTERY FOR DELL STREAK MINI 5 battery here? (Just check it out on ebay, i can't link it because i'm a new user)
Wondering if its worth getting it or if I should just get a cheaper pack with a charger and 3x 1800mAh batteries? Mainly looking for an extra battery to take with me on long car trips so I can use the phone more like a tablet, but I wouldn't hate having a longer lasting battery for daily use either and then using the stock battery as my extra.

this looks interesting..one thing good about it , is that is the same size as the original dell battery.

I think its a fake capacity, the largest capacity that fits as standard size offered by a decent battery manufacturer, Mugen Power is 1800mah, and if you read the threads here, there is a 2400mah extended battery that has to use a custom battery cover because the battery is twice the depth of the standard battery.
So, i think you will find its not really a 2430mah battery, but a 1800mah battery at best.

if it seems too good to be true...
The best bet is to get one of those external battery packs with 3000-6000mah and a spare cable.
Also be agressive in your control of screen brightness and data use

If you read the feedbacks of that seller on eBay. There are heaps of negative feedbacks from buyers calling him a CON.

I bought off amazon since it had to be shipped to India... think there was only 1 seller in Amazon and he seems genuine.

There's a point with batteries where to make them any more powerful you must make them bigger. If fitting 2430ma into an 1800ma package was possible Mugen would have done it, so yes the rating is a lie.

REF: Gold Battery 2430mAh on eBay...
Total fake and ripoff!! ...so dont be wasting your money...

Sorry. Thought you asked for the regular 2400mah.

hi, i bought this battery 2 mounth ago and my phone authonomy is double now. so dont coment if you dodnt try!

Do dell sell them?

Probably a con, but what the heck… I just purchased it. If it’s not 'as stated', I’ll report the bugger.

could keep us posted about this, i looked at the seller's feedback and seems it is fake but wondering if that is true.

The Americans have a saying "You can't put a quart in a pint pot" and that applies to battery power as well. Don't waste your money.

Irritatingly, battery capacity is only shown on the battery itself and not in the device’s battery info. So, is it really 2430mah? Don’t know. But there IS a difference. The 1530mah stock battery ran out of juice alarmingly quickly – like falling off a cliff - when at 30-40%, yet ‘Business Battery’ allows heavy use (downloads, browsing, video… etc) right down to single digits. So now I can use Streak much more (I’d say several hours more of constant use) when battery level is below 50% without worrying if it’s going to suddenly die on me. No gain between 100-50%, though.
I was prepared to slag this off, but from my experience it’s genuinely longer-lasting, especially at low battery levels. How long the battery itself will last only time will tell.
I’m not prepared to test it against Mugen’s 1800mah and spend near 30 quid (plus £18 p&p) in the process.

I've read elsewhere that the cheap Chinese batteries often don't report the available power in as many steps as a 'proper' one does, so they appear to fall slower.
I don't know how old your Dell battery is but it might not be as good as it used to be when new.

Yep, I had to replace the Dell battery (after about 10 months use) because over the past week it became completely unstable – dropping to 70% after 30min use, suddenly back up to 95%, and plummeting from then on. But the stock battery right from the start was always weakest when two-thirds empty, and it drained juice even on standby. Last night it was 100% or ‘fully charged’ for over 3 hours (mostly on standby and some light doc editing)… that had never happened before.
The thing is actually stamped ‘made in Japan’… aren’t Japanese products supposed to be expensive? Looks suspect, but whatever. If it becomes unstable after a month or two then sure, I’ll invest in a nice new Mugen or Dell replacement. But as of now I’m fairly content with a £13 Ecell batt.

Got one of these last week, & have put it through a few recharge cycles etc, unfortunately, it's no better than the stock battery
Oh well, it was worth a try..

As with all cheap batteries it has a short life - no more than 2 or 3 months before it starts to rapidly drain. As a temporary and inexpensive solution it's fine, but don’t expect long-lasting quality.

[Q]Extended Battery the size if OEM battery?

Like title says.. I've been trying to find a extended battery which has higher capacity yet the size of the original battery but no luck
Does anyone know if there is one and where to fine one
Thanks
Sent from my Nexus S using XDA App

are you sure that's even possible ? unless the battery was made of some other kind of materials, I have tyrouble seeing how you could store more power in the same battery size.
If you don't want a bigger phone, Your best bet would probably be to buy a second standard battery but it's a hassle to swap the battery when it's empty

If the battery is the same size it could in theory have more juice but it would be negligible. Seriously though, I picked up a charging cradle with battery charging slot and 2 spare batteries for $20. I also have a car charger and 3 chargers in my house. Unless you get a battery that is about double the size, you won't see a big difference and even then many batteries don't live up to their specs. Chargers and spare batteries are cheap. We're not dealing with smartphones of a decade ago where everything was proprietary and would cost at least $30 a pop.

I remember reading something about this... I think it might have even been on this forum but it was something along the lines of "Don't you think, if it were possible to fit more juice into the same size battery, that samsung wouldn't do that with their OEM batteries?"
Samsung, and I'm sure many other major device manufacturers don't just buy a battery off ebay and throw it in their phones. they spend time and money researching better battery technologies to get the best power/life they can.

It's my second day with an Andida 1850mAh battery, no big changes yet compared to my 8 month old 1500mAh OEM battery, i'll post back after a few complete drain and charge cycles.

After 3 complete charge cycle its a little bit better than OEM but no big improvement. I'll see in a few more days.

I finally get about 15% better battery life. For the 20$ it cost me, I'm happy.

How long have you had the battery? I'm looking for a new one as well but not if I am going to get scammed. Thanks!

Not Nexus related, but I have a vibrant that I got the Galaxy S 2 Epic 4G Touch battery for recently. Battery life went from about 6 hours to dead (month old 1500 mAh replacement battery bought at a phone hut) to 34 hours to dead (new samsung 1800mAh battery.) Nothing else changed.
My point is this:
1. If the above statements about samsung packing in as much as possible are true, why didn't the vibrant have a 1800mAh battery from the start? (hint, it is always about money.)
2. Take a crap 1500 mAh battery, slap a 1800 mAh sticker on it. People that buy these batteries will see an improvement because most generally they are replacing a worn out battery with a new one. Of course you will see an improvement, your worn out stock battery has only (arbitrary number) 600 mAh worth of usefulness left. The replacement is new and is not worn yet. (All arbitrary numbers follow) So, you will still see an improvement if you take a rated 1500mAh battery, that is labeled 1800mAh, but is in actuality only 1000mAh.
So asking if there is another, bigger, better battery for the Nexus made by Samsung, is a very valid question. So:

Because it is a device from 2 years ago (2010) and the S2 is from q3 2011. Maybe two years allowed them to cram more juice into the battery.
Maybe it wasn't viable then, to stick such a large battery, considering the power consumption of the vibrant compared to the S2. Maybe if they did the price would have gone up.
I highly doubt that Samsung would just stick different stickers on the same capacity batteries. maybe you had a defective or a non-original one. There are people that measure this kind of stuff. How much damage would Samsung's image suffer if someone found out that they sell a 1000 mAh battery with different labels and price tags?

"Take a crap 1500 mAh battery" In this case "crap"="non oem"
I figured that would be obvious with my prior "phone hut" comment. I guess not.

I am a big fan of the OEM batteries. I have not tested a non-oem battery that will perform anywhere close to the stated specifications so far.
If you guys find some good battery reviews, tests, etc. please post up.
Keep in mind that comparing a brand new "Craptastic Brand™" battery to your old worn out OEM battery is kind of pointless for getting a feel of the comparative quality/capacity of a battery.

Mugen Power Batteries

I though I share this site with those who don't know.
Mugen Power is a reputable aftermarket battery manufacturer, and you will find many good feedback, reviews and recommendations about Mugen batteries on XDA.
The main site is here: http://www.mugen-power-batteries.com/
I am myself a Mugen product user and I would like to share once again how amazed I am by their customer support and social network persence, like for example if you follow up Mugen Power on facebook http://www.facebook.com/MugenPowerBatteries, they give 7% discount on their stuff. Many fans on facebook represents brand loyalty to clients, and you can see many fan comments and simple questions which are answered accordingly. If you have problems with you battery, it drains quickly, it charges slowly they exchange without questioning. Worldwide shipping is free of charge. Overall it is worth noticing.
Concerning Verizon Moto Droid Bionic Mugen has 2 products:
Its a 2000mAh Extended Battery, it fits the original cover. Slightly more powerful than original just enough to resolve the issues that might accure with factory battery.
And for extra power there is 4000mAh Extended Battery which enlarges the phone with an extra replacement backdoor, but improves the battery life at least 2.5 times.
I hope this little review will help you in your quests for battery replacements.
For questions, ask their facebook or write directly on their site, I always got my responces there so far.
I have ordered myself the 4000mAh battery for testing, and hope to post user experience results as soon as the battery arrives.

If you could, let us know if that battery will fit under the OEM extended cover. If so it would make a nice upgrade.

that is exactly what i was going to ask. let us know please

I purchased the 2000mah mugen and it does fit under the OEM door.
Battery life with it though was actually less than the stock for me.
At times it would get really hot and just drain out when in use.
I keep it charged and use it as a spare in case I need it when taking long trips.
This is just my experience with it. Yours might be different, but as of now, I don't recommend the mugen 2000mah one.
Haven't tried the 4000.

That should not be normal. I had same sort of negative experience with my other phone (galaxy nexus); i have written Mugen about it and got my apology and warranty replacement without questioning that is why i have mentioned my total respect to their customer support earlier.
If your warranty is still valid you should definitely write them a note about your problem, maybe they will help you with how to root it or something, try this one:

@mercdoc and @Noob_In_Recovery
the 2000mAh version fits in original backdoor as @dellenrules says
and the 4000mAh is a big one, it shall arrive with extra backdoor to fit in the phone, i cannot wait mine to arrive!!

The mugen 2000mah battery in actually should last longer.
Because of how it's designed, it gets hotter quickly. As a result, it kills the battery a lot quicker.
When ever I get a phone, replace the battery with a mugen.
When I'm working in the office, it's pretty much "death by AC." My phone can last me all day with no problems.
When I'm on the road, at the gym, or any place where it isn't cool, the battery dies quickly.
No it isn't just a bad battery. I purchased 2 and they both behave the same way.
The stock battery is better for me since I'm not always in the office. I use the mugen as a backup and keep it charged and ready to go when I have to take those long trips.
I already get about 15 hours our of my stock battery on a single charge.
Not too worried about battery live at the moment.
Thanks for your concern.

Mugen Power 3600mAh Extended Battery for Samsung Droid Charge / US Cellular Samsung G
Comments of Mugen Power Battery from Facebook user Anlyn Bankos:
HLI-i510XL 3.7V for Samsung Charge: This battery was a complete waste of money. It was a gift and my dad seriously over paid for a battery that won't hold a charge. It's to the point where every day now I have to plug my phone in during the day b/c my phone says "battery low", I plug it in and "wow look at that - I'm charged to 100%". Imagine this happening 5+ times a day. I can't be without a charger because if I can't plug the phone in immediately, it dies. If I do plug it in, the battery miraculously recharges to 100% in mere seconds, only to go through the whole charade again 10 mins after I unplug the phone. I have dug out the original battery and am going back to that. Crappy product.

Thanks for the site information, good news for the facebook discount too, i did not know that.

I bought a Mugen 2000 mAh battery about six months ago. During that time it worked great, average time 16 - 18 hours according to Badass Battery Monitor. (For comparison, my standard 1735 mAh battery lasts about 12 hours. I mainly use WiFi and 3G, turning on 4G only when needed.) Then last week, the Mugen started falling off a cliff. It would go from 80% to 40% instantly and then drain to 0% in just a few minutes. This happened again and again. Finally I asked my wife to test it in her Bionic, just to rule out problems with my phone, and sure enough it behaved the same way with hers. So for $50 I got a decent increase in battery life but it only lasted 6 months. YMMV of course. Now I'm using the stock battery again and getting the standard 12 hours. I ended up ordering the 2670 mAh extended battery from VZW, which is currently on half-price sale for $25. It should be here tomorrow. Probably won't order from Mugen again in the future.

I love my 2750 extended battery.

7600 mAh battery?

I've currently got a Verizon Galaxy S3 with the Qcell extended battery. I've got the Note 2 on preorder and have already begun looking at extended batteries for it. Of course, the Qcell 6200 mah is going to be good: http://www.amazon.com/Extended-Comp...52674262&sr=1-2&keywords=galaxy++note+2+qcell
But, I was browsing ebay and noticed that there is a 7600 mah available. Has anyone tried this? Thanks.

There's a decent chance it's actually a 760 mAh battery lol. I'd go with a reputable brand (who still often advertise more mAh than they actually use)

Holy crap those batteries are huge!!! O.O
You must be on your phone 24/7 if you need a battery like that. The Note 2 can easily get through a whole day with the stock battery.

Well I'm a student and plan to use the phone a lot for a whole day, including reading pdf's and stuff on it. It will basicaly be a dual use phone and tablet. Therefore, I really need the battery.
I had the original Note before returning it because its battery life was so short. I could literally see the battery % draining while using it.

I am gussing those back cover replacement have no NFC, so be warned.
