[BATTERY] NEW 2800mah extended battery out!

Hey all!
I was looking for extended batteries for my Samsung Vibrant and I stumbled accross this awesome battery auction.
Now don't get TOO excited. This is just a $6 off of the final price of the battery. The battery itself is NOT out yet (will be VERY VERY soon) so he is just selling a $6 off of the price for $1. I talked with the seller and I got the specs for the battery.
Type: Lithiun-ion Polymer Battery, 3.7V
Size: 10mm thickness (1cm). Original battery is 6mm (0.6cm) thick so this is not TOO much fatter.
Capacity: 2800mah
Retail price (without coupon): $36
PRICE INCLUDES A BLACK BACK DOOR.
It is currently in production in manufacturing and should be out on the market very soon. If you're interested in the $6 coupon off the $36, click here.

Man I cannot wait. This is my only complaint with the vibrant as it stands!

I wonder if the new battery door will make the back flush by eliminating the small hump at the bottom of the phone? I love when Ebay is a source of new products. Who makes the beast?

Not sure on manufacturer yet but should be clear soon enough.

hmm... hard to put money down on an item that you don't even know how it looks like

they really need to post some pics of the item along with how the back sits

You guys just need to install juice defender. I can go 36 hours with moderate use without having to charge.

+1 on Juice Defender
Here's a screenshot of my battery life in the last 36 hours. I still have 9% remaining, so keep in mind that I can get 2+ hours.

what settings are you using to get that?

Man that app is really kinda confusing to figure out. I mean you can by tinkering, but wow.

Dang man, I installed juice defender and it EFFED my phone! It became so laggy that I couldn't really use it at all it took me a full 15 minutes just to get into the app manager to uninstall it...

Not sure what else you may have done to your phone but I have Juice Defender (Ultimate) on my Vibrant and my Wife's Slide and it works great. Since I get a lot of mail, text, and IM's I still can't go a full day but I am getting about double the battery life I had before I started using it.

Dont know if i would be comfortable with a thicker phone... an extra 5MM or so is rather thick. and i wouldnt be able to put it in my nice case that just came in the mail.
I got a car charger and USB cable for my desk at work and i just charge it as i need it. Mostly since im new to android and always playing with the damn thing is the reason i run low.

Another vote for Juice Defender/Ultimate Juice. On the weekends, my phone lasts over 30 hours with moderate use. During the week at work is somewhat of a different story. Running BT, music, and having to deal with poor service inside (phone constantly going in and out of service), I'm still able to get about 12-14 hours.
Overall a great app though.
As far as a thicker battery.....meh. Would definitely have to see the size difference first. And if it still fit in a case.

I think that battery is BS. It wouldnt fit in the phone.

Besides the weight you'll also have trouble finding a case to hold it.
I'm going the route of constructing a back-up battery using 4 AA rechargeable batteries NiMH (4x 1.2V = 5V, with 2800mAh AAs).
Got one of these with leads, on/off switch and cover. You can also get a squarish holder if you don't like the side-by-side layout.
I'll solder it to a mini USB cable, then use a mini to micro converter so that I can also charge mini USB phones. Parts ~$5 in parts.
If you want a fully assembled 4x AA one you can buy it here and here. They also have 1x AA and 2x AA versions, but I don't know how well those work.
Found this 2400mAh battery for the Vibrant here. Price is $59 and the picture doesn't look like the actual product.

I was thinking about gettin a bigger battery but then i found 2x BATTERY+dock CHARGER FOR SAMSUNG GALAXY S Vibrant # on ebay for 10$ and i thought i could just throw a spare battery in my pocket just in case my phone run out.
But..Are theses batteries as good and reliable as original one or the ones that phone store sell? Have you guys experienced any battery that sell for that low cost?

How about this 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...!

Review - Mugen Power 4500mAh Extended Battery (for HTC Thunderbolt)

I was recently given the opportunity to trial the Mugen Power 4500mAh battery. Ironically, the opportunity came up just was I was planning on flying cross country with my family, so I thought it would be an ideal time to test it out.
First things first, yes, it is big. Large. Huge. Yes, it is not “pretty” by any means and it takes away from the sleekness of the Thunderbolt. That is the only negative thing I can say.
The first day I turned it on at 2:00 AM Pacific time and it was NEVER turned off until 7:04 PM Pacific time. When I shut the phone off, it still had 50% of power left. Yes, you read that right, 50%. If you doubt my usage for the day, it was as follows:
I have four email accounts (one corporate account that uses Touchdown and three personal email addresses) that I monitor constantly. I am a heavy Facebook user as well. I also used Google Navigation to get to the airport (over an hour away from my house) and the same program to get to our destination on the east coast (one hour and 45 minutes away from the airport.). While on the plane I had it in airplane mode. It was used heavily by my children and I for games, etc. throughout the 5 hour flight. I was frankly amazed that it had that much power left after that full day. I NEVER plugged it in once during the trip.
I then switched over to the standard battery during our week on the east coast. I went through TWO standard batteries a day (EASILY) while using navigation, etc. I was lucky to make it through the entire day with those two batteries. There was a part of me that was longing for my “monster” to be put back on!
I used the Mugen battery again for the trip home. Reverse all of the previous information (Navigation, Airplane Mode for 5 ½ hours, MORE games and customization while in flight, etc.) and this time you can add in Mobile Hotspot and WiFi use once I was home. From 3:00 AM Pacific to 9 PM Pacific, I had 44% of the battery left. Again, I never plugged it in once.
Look, it is not pretty. It is big. It is beautiful though if you are on the road, on an airplane, on a long trip and/or are a power user and you don’t want to worry about plugging in, changing batteries, etc. This battery is now going to be readily available whenever I need that extra time or push from my Thunderbolt. Simply put, call it Beauty and the Beast. Check out Mugen Power Batteries on the web for more.

Nice review

post some pics and if its not bigger than the htc extended im down
Found this video
Its Fugly lol

That thing is freaking huge.

that's what she said

Why couldn't they just make the case like the 3500 it just looks stupid that way. That's pretty much the only reason I don't wanna buy it and the $100 price tag. They sell two 3500 and to covers along with a wall charger on eBay. For like $35 that sounds like a lot better deal.

That thing's $100? For $80, you can get a 16Ah (16000mAh) external battery on Amazon. It doesn't decrease the sleekness of the phone and will fit in a cargo pocket (and maybe even a fairly large hip pocket). That way, it still works when you switch phones. It has 5 USB ports, so you can charge lots of stuff. (No, not advertising, just demonstrating realistic specs. I know there are comparable models, this one is just the biggest one I found).

i currently have the HTC 2750mAh extended battery and got a silicone case for it.
if i get that 4500mAh battery, will i be able to use the same silicone case or have to wait yet again for new cases to become available?

That thing would definitely give you the juice you need but, dang! That is just about ugly lol. I mean if you need that much battery it would be perfect though. If you don't want that much bulk there are several other options you could go with. I saw on Amazon where you can get 2 1400 mah batteries and a wall charger for the batteries for $20! All the reviews seemed positive too. Just another option I guess.

are you the seller of that 2 slim combo or something?... i keep seeing people posting that package all over this forum.
if you even click on this thread thats a good indication that a high mAh battery is what you want and need.
hell, i have 4 1500mAh & 1 1600mAh battery that didnt cut it for me. before i knew it, a battery was dying and had to go through the bother of powering down, opening up, replacing, powering back up.... and in no time repeat.
im using an extended right now and plan to never use the slims again. hell, i should sell all of mine.

i doubt there will be a case for this unless Mugen themselves make it. there r cases for the regular extended battery cuz the battery is common n a lot of people have it. i doubt many people would have this huge thing so probably no cases will ever be released unless its by Mugen or a Mugen partner

One thing I always mention when defending my extended battery is the thickness-battery life trade-off and how, at the size of the HTC extended battery, it is worth the bulk for the change in battery life. I don't think i would be able to say the same for this. If I ever had to slap something that big on my Bolt it would have to last a week

Great review, thanks for it. The battery is quite big, but a must-have accessory when it comes to traveling.

Mophie pack or universal extended battery pack?

Not sure which to pick up for my One. Even with power saving and minimal "optional" usage (only doing GPS navigation I actually need, checking sites I need to, etc), I can barely get through a day. Maybe I was just spoiled by my previous Note 2.
Anyway, the Mophie case seems like my optimal option, and I honestly don't mind the added bulk or weight, but at $100, it's a little expensive obviously. And waiting for a price drop isn't really an option, since I'll probably be picking up the Note 3 later this year, or at the very least some other phone. I don't have any other devices (like a tablet) so having it be specific to the One isn't exactly a bad thing.
An external battery pack would be a lot cheaper per mAh, but not as convenient - unlike the Mophie, I'd have to remember to bring it with, possibly even bringing a bag if I wouldn't otherwise (I like to travel light and keep my pockets limited to keys, wallet, and phone). I'd probably be looking at the Anker Astro3E 10000mAh for $40 or Anker SlimTalk 3200mAh for $24.
To be honest, most of the time I'll need extra battery life, I'll probably know in advance and come prepared (and therefore be able to pack the external battery), but sometimes I'll run into a situation where I'll forget to charge the phone at work after extensive use, and get last minute plans for stuff out of the house and away from a charger, where I likely won't have a bag with me.
Thoughts? Maybe opinions on Mophie users, especially ones who also have external battery packs?

I'm in the same boat! But yeah I've ordered the Anker Astro Slim2 and the Motorola P4000, both are the same size of a phone and have a built in cable.

I have the Astro 3E 10,000 mah and I love it to death. It's seriously a life saver

Always go for the universal battery chargers (the good ones of course) if you change phones like me (every 6 months or so) your resale value isn't as good with phone battery packs

Get the battery and leave the case alone. It will serve you much better with faster charges and some will charge you phone up to 4 times. The iblason is trash and mophie is trash as well.

My Zero Lemon S7A battery case review

jlczl already has a youtube review up but here's my take on it. With no pictures. Lol
There is no getting around the size and weight of the case but make no mistake, this phone should last you at least 2-3 days of HEAVY usage. This is not a case for most to carry in their pants/jeans pockets. I'm usually carrying two phones with me in the same pocket (one from work, one personal) and even then, it's still thinner than this case with the phone on it. It also weighs less. While some people like my brother actually carries and uses ZeroLemon battery cases on a daily basis, most of us would only use it for specific scenarios, probably mostly during travel. Some would say, "well you can do the same with a battery pack". Of course you can but it's definitely not as convenient and you'll have to contend with a wire between the phone and battery. Speaking of battery packs, this case has a USB output so you can actually use it as a battery pack to charge other devices.
A few things that I don't like about the case is that when you're charging devices, the LED lights are lit up the entire time it's charging which, depending on the situation can be distracting. Not sure if it's just the one I have but that's my main gripe about this case. The specs list QC 2.0 for charging the S7A but I didn't notice it charging any faster than usual. Regardless of that, it would've been nice if the USB output for other devices was at QC 2.0 as well. Last but not least and should go without saying, you lose the waterproofing for the phone. Well, technically the phone is still waterproof but the case obviously is not. You still wouldn't want water to get between any charging devices whether they're waterproof or not.
All in all, ZeroLemon battery cases may not appeal to most but they definitely serve a niche group of consumers like my brother. Lol
One final thing that will probably please original Gameboy fans. The heft and size of it reminds me of the original Gameboy. It's almost as if I'm using a modern version of the Gameboy. If you've never played hours upon hours of the original Gameboy, you won't know I'm saying but if you did then you'll instantly be reminded of it. Lol
Another thing is I haven't seen a holster for this version. My bro's S4 or S5 (forgot which Galaxy he has) battery case came with a holster.

no pics! all good mate, nice review.
how much was the case?
would be good if you could test capacity more accurately, maybe turn on airplane mode, then turn on wifi and have youtube play continuous hd documentaries (auto play enabled) with screen brightness 100% and see how many hours it last?... no pressure, just curious

No time for that but it's fine to charge almost 2x from a dead battery. The efficiency rating isn't the best but it's not advertised as such either. I'd say,
anecdotally, it's about 70-75% efficiency which is about average.
