How about Mugen's 4700mAH built-in battery, huh? - JASJAR, XDA Exec, MDA Pro Accessories

First we have 3000mAH, then the 3800mAH and now the 4800mAH. Its getting better and better :lol:

I like how all the geeks in that thread are cracking up about it when you *know* they'll be the first in line with sweaty, crumpled bills in extended palms.... :lol:

I don't think so That was genuine ridicule. I wouldn't touch that battery with a 10ft pole nor would i recommend it to anyone.

My god! isn't the Universal big enough as it is?! ?

RE
Well, if you want power on-the-go then 4700mAH could be your answer otherwise bring your AC charger along

Personally I'd rather just buy an extra 3000mah battery and stick that somewhere in the car or my suitcase. Then if the battery runs out I'll just change...
No way I'm going to add another cm to my universal

If you want something ridiculous go for a windmill to charge your pda

Swapping batteries when using the phone and again swapping batteries when charging them is not a much better game, especially every time you forget to charge the second one. Here we have the extra centimeter but we also have three batteries in one!

Extra Batteries / Extended Batteries / Portable Chargers

The great question:
Is it better to 1) carry extra batteries with me and just trade them out as they die but maintain the light, sleek form factor of my EVO, 2) get an extended battery that will make my phone thicker and significantly heavier (resulting in fewer case choices or cradle fit issues) or 3) get an external travel battery that plugs into my phone via USB and recharges my battery with another battery?
Well each has it's pluses and minuses:
1) Extra Batteries: The problem is, of course, transporting them. You also need to buy an external charging dock to keep them juiced and the phone has to be taken apart to replace them. With some cases such as the Otter Defender, this can be a significant hassle. As far as transporting them, it is easy to buy an unobtrusive $10 leather zippered pouch and carry them that way.
2) Extended Batteries: Easily charged in your phone and not requiring replacement during a long day, these batteries are an attractive option. However, say goodbye to your sleek and slim EVO. These add significant heft to your device and make it twice as thick. Also, unless you pay top dollar for a name brand, you risk having a "fake" product of questionable build and even more questionable capacity. Watch a video of a "Lion" battery fire and you will realize you don't want to play with cheap knockoffs any more than you would buy knockoff medicine from a guy in China to save a few bucks. And oh yeah, good luck finding a case that fits your "pregnant" evo.
3) Portable Battery Chargers: Again, these can be an attractive solution. They can come in many sizes (up to 8000 mah) and can recharge your phone even as you use it. The issue is bulk. One 5400 mah device is about the size of your EVO. So, imagine carrying 2 EVO's with you (never mind the USB cord). Compare this to carrying a spare 1500 mah battery in a small leather pouch (which you would hardly notice is even there). Also, these charge your phone using USB cable. This means a maximum charging rate of 500 ma. If you are using your phone for power intensive tasks such as Google Navigation, your phone will still run out of power even if it is plugged in.
CONCLUSION:
Weighing all of the factors, I recommend getting a couple extra 1500 to 1750 mah OEM batteries along with a wall charger (don't be cheap - these things can go boom). Simply carry them in a small zippered leather pouch you can pick up anywhere they sell wallets. A fully charged battery in your phone and just one of these "stand-bys" should get you through even the most grueling day.
The only hassle here is physically switching them out; however, that is less of a hassle than dealing with a "double-thick EVO" extended battery or an "extra EVO in your pocket" external travel battery. You should only have to change the battery out once in a 24 hour period. With the other solutions, you have to deal with their negative aspects 24/7.
You keep your slim form factor, you not are limited by case choices and you extend your power - win.
** This conclusion assumes the user will eventually have access to AC power to recharge sometime in a 24 hour period. For camping, etc, where you will be away from wall/car juice for extended period, the external travel battery may be your best choice (and you can carry it in your backpack).
It looks dumb and feels kind of bulky, but there is no way I'm turning off my phone, taking off the case, and prying off that flimsy batter door all of the time. I hate that process and feel like something is breaking every time. Big pregnant evo for me.
I still have to laugh when people talk about the added "bulk" extended batteries like the Seidio adds to the phone . Most of the time people who see my phone and realize I have an extended battery usually respond with "Well thats not that much bigger" . Im not shooting down your opinion I just feel this obsession with have a super thin phone is a bit overboard . Hell I remember years ago when phones were on the trend of being super small , hell I remember seeing one model that when it folded up I swore the damn thing was just alittle bitter than a book of matches . Now the trend seems to be bigger phones or atleast leaning in that direction (examples : HTC EVO , DROID X , Epic 4G isnt small either) . Overall like the OP outlined it comes down to a choice , longevity using all the features of the phone (bigger batter) or slim phone with "enough" power to make it through the day if you micro manage all the features on the phone . Ive tried both worlds , Ive tried the stock battery which did make it through the day but just barely . I currently have the 3500mah battery installed and I can tell you this now I wouldnt go back to the stock battery . The added size now fits the size of the phone in my mind . The phone is already tall and wide , Hell the Droid X is even taller and wider (actutal casing of the phone not the screen) . In the end its your choice and its your phone , whatever makes you happy with it you go with it . Screw what everyone else might say about it LOL

As a business man who wears a suit every day, my biggest issue is that there is no way to carry my phone (other than a belt clip which is way too geeky for me) in my suit pocket or pants without looking like I have either breast implants or an erection.
Actually, you have your "pregnant" EVO "all the time". You only have to change your battery once Still, everyone has their preference and that's why I created the thread.
** Being a flash-a-holic, I have become quite accustomed to pulling my battery (boot loops and all) so I am probably less intimidated by the process than the average user. For me, changing a battery out takes maybe 10 seconds at the most. When compared to carrying around a thicker, heavier phone all day, the choice is clear (10 seconds of hassle vs 24/7 discomfort).
Again, no "right" answer here.
I use spare batteries. I have an extended but I hate the way it makes my phone look and feel. I keep a couple charged spares in the car at all times and another couple in my computer bag just in case. I would much rather do that then have an ugly block sticking out the back of my phone. My phone lasts well over a day on a charge so I never really end up swapping them out except for in the morning when I put a fresh one in. I usually still have about 50% left when I swap them out in the morning. I never charge my phone directly, I always just swap the battery with a fresh one and charge them with my wall charger. It only takes a minute to swap them and the daily reboot never hurts. I bought all my batteries on ebay (except for my seidio extended which NEVER gets used) and all eight of them cost me about $50 combined, which is cheaper than the one seidio.

+1 My reasoning exactly.
This is purely theory, but I have the feeling that younger users and those in manual labor type jobs will opt for the extended battery, whereas those of us where we have to wear a suit to work and sit at a desk or visit clients all day would prefer the swap-out just for appearance sake. A construction foreman is not going to want to swap out a battery with dirty hands in 30 degree cold but he(she) won't mind how the fatter phone looks.
In conclusion, those more concerned with the look and feel of the phone will opt for extra oem's, those who are looking for pure utility will opt for extended.
I've had my EVO for almost a full month, and yet its still caseless and exposed because of this dilemma. I'm leaning more towards keeping it slim and having a wide variety of cases to choose from. Obviously going to something like the 3500 would require a new battery door. So, what's the maximum battery size the EVO can hold before needing the new door? I've seen 1600, 1700, 1750, 1800, and 2000 mah batteries. Also, would these slightly stronger batteries make ANY difference? I've seen reports saying those batteries are tested and not actually as strong as they say.
Thanks in advance....

ROOT YOUR PHONE. solves all the troubles of extra batterys. I have 4 batterys i bought before rooting. Now they just sit in different areas around the house and car because i never use them. Easily 18hours of battery with decent amount of use.
Well, I super use my phone;all day pounding.....even the Sprint extended barely makes it about 18hrs.....so I prefer the constant functionality...!

So Ebay batteries?

So I know there are a couple of posts on here but I have found them a little hard to follow. I just got my captivate last sunday and on the stock 2.1 rogers rom I noticed that the battery life was very poor. Since then I am now running cog 3.01 i think and my battery life is now alot longer than before.
For the way I would like to use my phone It is still not enough for what would make me happy. my phone is unplugged at 6:00 am and when i get home by 5 it used to be dead but after "breaking in the battery" and the new rom i get home with about %15 percent battery.
I just bought a triple battery pack off of ebay for $10. these batteries are rated at 1500 mAh, the same as the battery that came with my phone. I am just wondering what I can expect from these batteries.
My plan is to drain two of them completely then leave them in my desk drawer(from what I have read if you plan on storing batteries they should be completely drained first) and use one of them plus my oem battery daily(until they start to lose performance). Again does anyone have any experience with a battery of the sort or any similar third party battery?
they are no where as good as samsung oem battery. even though it says 1500mah it is not or will drop drastically after a month or so of use...i've bought a lot of those batteries from ebay and they always like that even some other well known companies like Seidio do not compare with manufacture's batteries. the difference is usable capacity, oem batteries are around 95% compared to cheap chinese ones that are anywhere from 60-80%.
haha thanks that makes sense why they are so cheap, well i will probs by three new ones every months or so.
I have those ebay batteries. I bought the kit that comes with two batteries and an external charger for about $10.
The ebay battery is has about 60-70% of the power of the OEM battery. I have no real hard evidence just from using it for the past 2 months or so.
I am ok that it is does not last as long as OEM because it was only $10 and it came with the external charger. I love the external charger because it allows me to charge a spare battery while I keep one in my phone.

I bought the same ensemble, with essentially the same results excepting perhaps that one of my replacement batteries seems to underperform with about 40% of OEM battery life.
That said, for $10... they're very handy as backups. They'll easily give you a few more hours in a pinch, which is essentially just what I was looking for. I really have no complaints in that respect.
The best strategy for battery life I've found is to buy a handful of wall adapters and position them in places you spend a lot of time at, and to develop a habit of plugging in when you're not moving around.
Sad but true, but mediocre battery life is just kind of a way of life for these (and really all) high-performance Android devices. Excepting getting an outsized and expensive battery replacement like the Seidio 3500 mAh that all but prevents use with many accessories and cases, a couple wall chargers and a car charger are effective if mildly annoying means of managing it.
These generic Hong Kong replacements are entirely effective as emergency supplements, but you'll find yourself preferring the OEM cell still.
Yep I mean for $20 I have two charges and 4 batteries so if I need to go without power , even if not a 100% match for the oem power, it is still damn cheap.
I also got one of these from ebay.
I got the 2x 1500mah batteries + Battery Charger combo.
I must say I am impressed. They are the same quality as my OEM battery. Its so convenient. I never have to run to a charger anymore. Just keep the spare battery in my car or wherever and just pop it in and carry on with my daily business.
When I get home, I just re-charge all the batteries. The Battery Charger even has an LED Light that tells you when its finished. "RED: while charging" and "BLUE: when finished". Charging takes about roughly 3 hours, (just like OEM).
Edit: Been using this for about a month so far. With no problems.. Its the best feeling. My phone is never plugged in anymore. And, I don't have to "pinch the settings" to make my phone last.
IE. lowering brightness to 10%, turning sync off, turning wireless networks off, etc.
HIGHLY RECOMMEND!
only crappy thing is??? I plan to sell this phone soon, when the Galaxy S 2 comes out, if the specs are good enough.

Would you mind posting the link or giving us the name of the exact vendor you ordered from?... I'm about to order the 2xbatteries and charger combo, but just want to make sure I get batteries that are half way decent. When I search on eBay I get about 20 vendors selling similar combos and given that in HK they're celebrating Chinese New Year... most won't fulfill orders until next week.
i wouldnt waste your money unless you just want an extra.

1700mAh or 1650mAh batteries - Has anyone tried them?

For those of us who don't want a fat new battery door on our phones, but want to improve on the stock battery, it seems there aren't many choices. Currently there is the overpriced and underhyped "1600"mAh from Seidio which I don't think I'm willing to pay for considering the reviews I've seen.
There's a 1650mAh from Mugen Power which I know very little about. I considered it, but for $45 and without any knowledge of its performance, this is a tough purchase for me. Anybody tried this one?
There's another one at HTC Express that's claiming 1700mAh, and I haven't really found a whole lot of reviews on it aside from a forum post or two in other places. Has anybody given this battery a shot? They're pretty cheap, (2 batteries and a wall charger for $35) so I think I might try it just for kicks.
I got the HTC Express set - two "1700mAH" batteries and a wall charger. Paid about $20 shipped on ebay from chichitec.
In short, the wall charger is crap. Half the time, the indicator light doesn't light, so I'm not sure if it's charging or not. It feels like cheap plastic.
Let me get straight to the point about the batteries - they're the same rating as the stock, the only thing 1700mAH about these is the writing on the labels. They're 1350mAH batteries like the one that came with it. They don't last any longer than the stock, maybe a bit less, but not enough to tell a difference.
That said, $20 for two backup batteries isn't too bad. I just don't know how long they will last - cheap batteries tend to die more quickly.
I got the same package for about $25 on amazon (via chickitek). Anyway, the charger works well for me and I haven't had the same issues as the previous poster. The batteries definitely are lasting as long if not longer than the stock. I'm rooted w/ Bamf 1.6.3 and undervolted a bit and I'm still at about 50-65% after about 12-16 hours. With that being said, I mainly am on Wifi so very little 4G.
I tried the Seidio battery that claims 1600/1700 and it basically wouldn't allow my GPS to work. Haven't had the same issues with these and on top of that, these are MUCH cheaper.
they probably won't last forever as the last poster mentioned, but they're doing great for now...just rotating the three batteries I now have.
Ditto the above posters. No regular-sized battery available will be larger in capacity than stock. These "1700mah" batteries are some of the better replacement batteries around, but don't think for a moment that they're better than stock. For better battery life without a pregnant phone, battery stat calibration and system management (governor, undervolting, data sync scheduling, etc.) are your only options.

Agreed 100%.
They batteries are no better than stock and the indicator lights on my charger started going in and out after 1 day of use. It does still work though.
i have the 1600mAh Seido one and theres practically no difference between that and the stock.
i still have the stock 1500mAh and 2 MyTouch 4G 1500mAh batteries as well.
pretty much i keep them all charged and when one craps out i switch to another.
[EDIT]: oh and yeah, you can use MyTouch 4G aka HTC Merge aka 42100 batteries in the Thunderbolt

[DIY] An OEM quality 3500mAh battery

I was asked for more information after mentioning this in another thread. I felt like it might generate some questions, so it should have it's own thread.
I wanted more power, but the cheap extended batteries are, well, cheap.
They are OK for the price I suppose, but they lose power quickly and in many cases aren't any better than the stock battery. I wanted a real increase as well, the 2000 from Samsung wasn't going to cut it. So, what to do? Connect 2 OEM standard batteries together!
Materials:
An extended battery back cover from a cheap ebay battery or a friend, etc. The stock Samsung "extended" back cover from the 2000 won't work. I used the one from a Hyperion "3500".
2 OEM 1750mAh batteries (shimshop on ebay has the real deal, about $30/per)
Soldering skill and equipment.
Directions:
Remove the sticker covering the battery. It peels off without too much hassle. You will be left with a bare battery with the NFC antenna on one side. I've attached some images so you can see what they look like taken apart.
Remove the plastic cover on the side with the holes for the battery to connect to the phone.
Now you have a circuit board that is kind of a pain to work with. Both ends you can get to are (+) terminals, as is the metal case of the battery. The (-) terminal is in the center of the battery, see the little hole in the center of the PCB, that's your other terminal. How to connect? Well... There are a couple options. Here's what I did.
Peel up the NFC antenna and let it hang there.
Use a Dremel with a cut-off wheel to cut through the metal connections from the battery to the PCB on the small ends of the PCB.
GENTLY lift the PCB up a little so you can get under there.
On one battery, remove the PCB entirely. Just wiggle it back and forth a bit or use wire cutters to disconnect the (-) terminal. The metal tabs break off EASY. Peel up the NFC sticker as well and just put that bit aside.
Put the second battery over the first. Secure with a bit of tape or something to make soldering easier.
Solder a piece of wire between the two (-) terminals. It doesn't have to be huge. 18ga should be plenty. It's short and likely won't ever see more than about 1A. NOTE: As I mentioned the ENTIRE METAL CASE of the battery is (+). If you short this wire to the metal case, it will get VERY HOT, VERY QUICKLY. DON'T DO THAT. It's bad for the battery, and for you.
Hopefully, you didn't break the (-) terminal off the second battery on the previous step.
Now gently press the PCB back into place on the lower battery. You might have to use a knife to cut some of the plastic between the PCB and the battery to make room for the little wire.
Line it up carefully, as close as you can with both sides and tape it down. Now solder a short wire between both (+) terminals on the battery. You can use the wire and solder to bridge the gap to the PCB from cutting it off before.
Now you have this NFC antenna in the way. Use a small piece of the sticker as insulation under the top 1/2" or so of the antenna on the back. Just to make certain that nothing will short to it. (I don't think it will, but it's cheap insurance) And set the NFC antenna on the new back of the battery. It won't fit quite right, and will overhang a bit. That's what the sticker is for. You could try to extend the connection, but it's more trouble than it's worth.
Remove your earlier tape holding things together.
Use the two stickers you removed from the batteries to cover them back up, sticking the NFC antenna down in the process. Well, most of it anyway.
Now you can try to cut down the tabs on the top plastic to fit properly so you can put it back on.. but I didn't bother. Once I made enough space, it got really flimsy and broke easily.
Now test the connections on the PCB with a voltmeter. Make sure you don't have polarity wrong or anything. Pretty hard to do, but you're going to put it in a $500 phone, so watch it.
If it looks good, put it in the phone and power up. It should work fine. Put the back cover on, and maybe get a case. I'm using the cheap bumper case from ebay. It leaves the back exposed, so just about any battery will fit. It looks a little ghetto before the cover, but it works fine. And it's made from OEM cells, they even have "Samsung" and part numbers laser etched into the metal body. So it will perform to spec, tested with a meter, last as long as a stock battery, which should be a couple years, and if you aren't completely stupid with a soldering iron, be as safe as a stock battery.
Nice hack. I just wanted to point out though that this can be very dangerous. Potentially causing a fire.
Scroll down to the "Cell phone and Camcorder batteries" section:
http://www.ladyada.net/learn/lipoly/
I also found this:
"When using multiple LiPo cells (parallel or series), they have to be charged with a special charger just for them that has been calibrated and is accurate. Then they need to be balanced out with a balancer (some chargers are able to balance themselves or support balancer attachements). So LiPo packs often have a special balancing plug that allows access to all individual cells inside a pack that is only used during charging. The charging is done through the primary terminals, and then the balancer plug is used to top off all the cells to the same voltage. As long as you use a balancer on all the cells somewhere along the line (preferably simulatenously).
It's best to balance all the cells as close to simultaneous as possible. Not a problem if all cells are in the same pack since the charger and balancer do them all simulatenously (duh!). If you use two packs you could charge them separately (I suppose you could charge them simulateously by connecting them in parallel also... as long as they don't get overcharged), and then top of them off separately. But it's probably best to connect all the cells in both packs to the balancer simulateously via the balancer plugs so the balancer monitors and tops off all the individual cells in both packs simutaneously. Depends on what the charger can do.
Still...I'd stick a diode on each pack to prevent one from charging into the other and read up more about it (you never do seem to see Lipo packs where cells are in parallel to increase capacity. They just use bigger cells. There may be a technical reason why they are never seen in parallel within a pack. Possibly due to cells charging other cells. I'd google more about it from RC truck and plane websites."
I don't want anyone getting hurt so make sure it's safe.
*paging Fire Marshall Bill*
On a serious note, it seems cheaper though to just buy a Siedo or Mugen extended battery, when you add up the cost of the battery cover, and the two OEM batteries and the materials. Nonetheless, I hope it works out for you as you put so much effort in to it.

I agree!
Other testing of sedio and mugen didn't impress me for the premium price. Every extended battery for cell phones I've ever seen used this same arrangement. Radio control people do it all the time as well. The RC guys have shown that parallel cells are perfectly safe for years.
Series packs need balance taps and such, but cells in parallel balance themselves. You can't really use a balance tap on parallel cells anyway. The voltage sense would be the combined voltage. The internal resistance of the cells limits the cross cell current as well. RC users do this with 6 cell series packs that have much higher capacity. The only difference is longer wires.
Wish you had pics for each step but nice write up. 2 2100 extended batteries would be even better!

do you have a pic of the battery in the phone?
there are lots of people here that seem to think the mugen and siedo batteries are as good as oem. probably because they write premium a lot on their website and charge double the price of oem. im sure your power pack will last longer than any other extended battery in the 3000mah range.
I'll take a pic once I get to a camera.
Battery ordered and will be in touch with a bench tech in my HQ that is a master at soldering, I'll explain what I need done and hope for the best. I'm also contacting seidio about ordering an extended battery cover by itself.

Here's a pic of the battery installed in the phone. If you want to see with the cover on, really, look at any extended battery thread. They all look about the same, and yours will depend on what cover you get to put on the phone. You can see the NFC antenna peeking out on the top. It doesn't seem to cause any issues so I didn't bother to try extending the leads or anything. And doing that might cause tuning issues, though I'm not sure what frequency is used so it's hard to say.

looks good, is it the battery the same thickness as those 3500mah extended batteries?
have you thought about putting a bunch of those cheap 5 dollar oem batteries from amazon together to make a big external power pack? maybe have them in a 2.5in external hard drive case or something. do you know if you would need a board for this?
the whole point of this was because those cheap chinese batteries suck. With this you know you are getting twice the capacity as your stock battery. This is the one thing I miss from my thunderbolt, my 2750mah extended battery was oem so I knew what i was getting.

looks good, is it the battery the same thickness as those 3500mah extended batteries?

Just about yes. I chose not to use the oem 2000 batteries as i didn't think the extra thickness would fit under the cover i have.
And no, i wouldn't use the cheap batteries for an external. If i wanted to do an external, I'd use an RC pack in a case like the hdd case mentioned.
i was talking about oem batteries for older phones like the captivate and droid X. you can get them for around $5 now or you think those are fake?

Quite possibly. I doubt real OEM batteries are available for that little, even for phones a few years old.

zero lemon is the best as it holds 3 times as much charge as the original battery.
mugen has the convenience of worldwide shipping and the best battery cover design, but is very expensive for a battery that only offers 2 times as much as the original battery.
most external batteries are inconvenient because you'd be carrying a 2nd device and a cable with you at all times, but they can be used for other devices too(tablet, camera)
there are also battery cases which attach directly to your phone, but they don't work for other devices and are bulkier than extended batteries.
my advice is to get a zero lemon, see if you can get an nfc antenna if you want to use nfc, and get a large external battery for vacations and if you have multiple devices that charge through a USB cable.

Tks for sharing/suggestion.......................really appreciate . Atleast someone cared to post
I am also planning to buy 0lemon but i am curious (kindof scared) how much weight will it add to n2
i dont carry my ipad to vocations. and its very often that i go on vocation :silly: But again the weight which will b added to n2 by 0lemon is wat i wish to know.
And yes i agree that carrying xternal batteries will be pain in the @ss
zero lemon doesn't ship here so i never got a chance to try it, but the mugen battery adds quite a bit of weight so i imagine you'd notice the zero lemon's extra weight even more.
