Verdict? Seidio 3500 mah or Sprint 2600 mah?

So what's the verdict? I've read tons of threads on these two batteries, all good things but my question is, if the Seidio 3500mah has more power, why not get that one over the sprint's 2600mah? Just makes more sense to.
from my understanding:
1) They are the same size
Only drawback from getting the Seidio would be:
1) There are reports of the back cover not completely "fitting" properly on the EVO, is this still the problem or have they fixed their back cover for a more snugged fit?
2) Sprint's battery comes with two color backing, white and black
Your impressions? What would you get?

Well one clear benefit of the Seido battery is that they also make a case that fits it. I don't know what shape the back on the Sprint model is but unless it is like the Seido you wont find a case to fit.

I can see a potential advantage to the HTC 2600mAh battery:
It's pretty apparent that the Evo has some issues charging extended batteries. There seems to be some kind of charging limit which can stop the charge cycle prematurely when you charge them in-phone. Being as the 2600mAh extended battery is an OEM aftermarket part it stands to reason that HTC might be working on a fix for that, but there's no guarantee that the same fix will work for a battery with ~35% more capacity that the OEM extended battery.
One possible scenario is the battery may talk with the phone (handshaking) via the extra contacts on the battery. That's actually pretty common with cameras and camcorders. For example, my Panasonic camcorder automatically adjusts the "Time Remaining" display when I put a larger Panasonic battery pack on it but the display doesn't even work when I use a brand-X pack.
But the truth of the matter is there is no guarantee that HTC is even working on a fix for it's own extended battery and if that's the case, the extra 35% capacity and the fact that Seidio offers cases and other accessories which support their extended battery gives the advantage to the 3500mAh battery.
However: batteryboss.org reports that the 3500mAh Seidio battery actually has only 2821mAh of usable capacity which is only 81% of the published capacity. Unfortunately there is no like & kind data on the HTC battery to compare that to.

as far as the back cover goes on the Seidio, it fits VERY tight.... this suprises me because it came with one of the tabs broken. (i superglued it back on, who knows if it will stay?)
It lasts me all day long so far, I have been trying to run it down so I can get a full charge at night. I know that conditioning is not "required" with these types batteries, but I still like to do it anyway.
It does seem to drop to around 70% rather quickly, but the lower the battery gets, it seems the longer it takes to display a lower percentage.

I had both but stayed with the seidio only cause they had a case for it , I got the shell case just covers the back and sides , but as for battery life am only getting 2hrs more than the sprint of course with my type of usage which is heavy.. so there both good just depends if you want a case now or wait till sprint releases cases for theres...

I have the seidio battery, which has a back cover that fits pretty snug, despite coming with one broken clip.
The battery capacity is confusing. I charge it until the light turns green, with the phone on. It will drop 20-30% really fast, then decreases slowly.
If I charge it until the light turns green, then turn it off and plug it in, it will charge more until the light turns green again. As soon as I turn it on, it drops to 96% by the time the phone starts up.
I plan to keep doing this, as I had a simillar problem with an HTC Mogul, however that phone would just freeze at the 80% threshold, and each time I did it raised that threshold to a higher percentage before it would crash. I know this phone is not crashing, but I wonder if there is some OS level driver or setting that needs to be adjusted or hacked? If there is, I have NO clue how to do this.

[Q] Mugen Battery strangeness...

This is my first post on here,but I've been lurking for ages I just bought a Mugen 3200mAh battery from MugenBattery.com.I already know about not having to condition it(lithium ion),so I ignored the instructions about cycling it and plugged it in and used it right away,and at first it seemed okay for around an hour(I didnt use it at all up to this point,just left it there until I needed it).When I went to unlock my Vibrant from suspend(pushing on the power button),the phone shut off and seemed like it was rebooting...but it just had the first screen you see(the one with Samsung and Vibrant on it) blinking on and off,even when I plugged in the charger in this state,all that popped up was a battery that also blinked on and off.The only way to get it going again was to pull and replace the battery,and it went back on again...then did this all over again when it went into suspend and I tried to unlock it.All the while,the battery stated it had around 75% power,so I have no idea what could have caused this.I put my cheep chinese 2700mAh battery back in and all was well again,so I know its the battery,not the phone.Anyone else have or seen this problem before?This is the most expensive battrery I have ever purchased for a phone at $88.00US....I hate to think that a cheep($20.00US) chinese battery has better quality control than it....

i think you need to charge it for 12 hours first.

Thanks,you were right! An overnight charge of around 12 hours did it.This is the first phone battery I had to do that with to get them to just work at all.Seems to work just fine now Again,thank you!

Let us know how long the battery is lasting once you get a few cycles please!

Yeah, you should run the battery dry, recharge, run dry, recharge and after a few cycles your life should improve.

Will do,just need a few days to do it,its lasting a looooong time!

NO, NO, NO. PLEASE stop spreading bad information. This will HARM the battery, and will have 0 benefit. The only "benefit" you can get from this is that the battery meter on the phone's firmware will be calibrated to show a more correct remaining %. You can achieve the same by charging the phone 100% (overnight) going to clockwork recovery and selecting 'wipe battery stats'. Calibrated or not, the battery will last the same, regardless of what % left its showing.
Again for posterity, REPEATED DISCHARGING OF LI-ION BELOW 20% IS BAD FOR THE BATTERY, IT'S PHYSICALLY IMPOSSIBLE FOR IT TO GET BETTER.

I am having a similar issue with a battery that I ordered off of ebay. It's 3500mah.
When I plug it in it will turn off and get stuck in a boot loop on the vibrant screen, but if it is off then it won't turn on at all when plugged in. It has been plugged in for 9 hours so far and it doesn't even show the charging animation or anything.
Normal? Or is the battery defective?
Thanks.

Ok. After charging it overnight and still nothing, I'm going to assume its broken. Thanks.

...and it does get a bit bulky,weight goes up to about double the amount,but it is so worth it,and then some!!I went from 6 hours on the stock battery to over 18 with the Mugen,and thats with heavy use(full brightness/live wallpaper,etc.).If you dont have access to a charger outside your home,this is a great buy,and you know the quality is there,unlike the uncertainty of the cheep chinese ones.Highly recommended!

The OS needs to learn your new battery. Just takes time and usage.

just bought 3000 mah
just bought one from accessory geeks, it came 70% charged, and am updating battery stats after a full charge, during stat recalibration, power is iffy. will update, and am considering mugen. any suggestions?

I am not so sure about your information. This is what DHGate, a wholesale Chinese online store wrote about the 3000mah battery for Galaxy S [not MUGGEN!]
How to use a new battery:
1. First when you received the battery,. you need to release the power in the battery, just put it into your phone without charging.
2. After the battery power is out, please charge it about 12 hours in first three times.
3. So the battery will be actived. So you can just charge it about 5-7 hours when use in the further.

No controversies at all. Your info from the link is outright wrong.
Mannymal is correct on this one.

I also have this battery. By the time I got it, Team Whiskeys roms had gotten good enough to where I didn't need an extended battery for day to day use (stock battery usually has 30-40% when i go to bed), but I do use it when I travel, so I don't have to worry about using it like crazy. The battery lasts a long time, probably like 2 or 3 days if I actually tried to drain it, at least. And it's definitely adds bulk, but it's reasonably well made and feels sturdy.
My only complaint is that I sometimes cover the speaker with my finger when I want to silence it real quick, and it doesn't work with this because the cover's so far from the speaker. But that's just my weird thing.
Also, yeah, don't kill your battery. No es bueno.

What is this? How do I read?

I use a seido innocell battery and it works great after a few over night charges. I get about 8 hours average of talk time. The battery is pretty small compared to the one accessory greeks sell. Even though the ah battery ia twenty five dollars, that is like the entry level name brand battery, it will lady you a while longer than the cheap ones on ebay, but I don't knower about the ones on ebay although I do know about the one ag sells skies down charging after about 45 percent charging. The seido is charging pretty fast for me and is half the price of a mugen, the next battery I'm going to buy will be the nugent, not because I need it, just
Cause I want to enjoy it.

samsung sII battery case

Just got it in the mail - had pre-ordered it from Mobile Fun about two weeks ago.
Someone else posted pics already, but couldn't find the thread - here are my own.
Note, the case acts as a battery charger, and starts delivery electricity as soon as you put the phone in. There is no switch on it. I'll have to see in the coming days, but it looks like it's necessary to only put the pack on when you need it.
Things I fear but may be unfounded:
it won't be practical to leave the case on at all times
need an extra charger to charge them seperatly and efficiently
I hope I'm wrong, and hope I can just keep it on at all times, and charge both the battery and phone at the same time using one charger.
Thanks to Eiraku posting in this thread, I was able to find the original thread for this battery pack:
http://forum.xda-developers.com/showthread.php?t=1110441
Mods please feel free to merge subjects.

Here are more pics

Isnt it a bit harmful to always have the battery at 100% charge level and even have trickle charge, they should have implemented a switch or at least some control mechanism to have it start charging only at around 50-80%

I think you're right, and indeed, the case start charging the phone even if the phone's battery is full.
From the manual:
"When not in use, remove your phone from the power pack."
Kinda of a let down. But I'm still happy to have it for my asian trip at the end of the week - electricity will sometimes be a luxury.

The purpose of this case is kinda moot if it does not have a switch and cant be kept in use.

Thanxs for the pics...I ordered this case from expansys a month ago and am still waiting on it to ship. Looks great.

So what is the purpose of this button

There IS no such button. Only the battery tester button (which is useless).
Cost cutting, Samsung? You delayed the battery pack to remove that freaking power toggle?
Personally I can't wait for PowerSkin to come up with something better (OR that urban legend official 2000mah internal extended battery with new cover to come out). But as of rite now, I'll take what I can get.
To OP: thanks for the nice pics. They're much better than mine anyway. And welcome to the club!

There is indeed a button as indicated on the pic you have there, but on mine, it doesn't quite look like that. There is no marking on it or next to it - it's a simple push button which function is to indicate battery level. When you push it, the battery indicator will light up green, blue or red according to its energy level.
The pic you have may be a prototype or maybe a different version other people are going to get?

Without power toggle
I will cancel the order

Guys,
Surely just because there is more power available behind the standard battery, doesn't mean the phone will suddenly start drawing more power from it?. A car doesn't consume more petrol when the tank is full... how would this be any different to putting a ...say 2000 mAH battery (if it becomes available) instead of the original OEM battery??..
More mAH added by the sleeve should give extra run time...
Riz

I'm no electrician, but I like the full tank analogy.
Imagine the tank is full, but let's say I keep pouring fuel in the tank while the engine is running ... kinda of a waste as the extra fuel will spill - not to mention the danger.
So the question here, if the energy or extra energy delivered by the battery isn't being consumed, is it wasted? Is there danger if there is "spillage" in the form of heat? This phone can already get incredibly hot it you use it as a GPS for an extended period of time.
I'm still concerned about what the manual says about removing the pack when unused.

Actually, I have all confidence that this is a "smart" charger, in the sense that it will only top up the internal battery as necessary.
Using it as an "extender", I have no issues getting 3-4h extra on really heavy, constant screen on 3g surfing. It didn't even get hot at all, so power was NOT needlessly drained.
As a "charger", I got from 6% to about 42% from a fully charged extpack. In this config, the case did get quite warm, which indicated that it was quickly expending its reserves to charge the SGS2.
For a 1300-ish mah pack, this is more then consistant performance in my book, from my experinces from owning multiple iPhone 4 batt cases.
Only issue is with the lack of power toggle, there's much less flexibility allowed. You can't choose to keep the extpack as an emergency reserve UNLESS you take it out.
Also, it only takes in 700ma (the Samsung charger is rated at 750) and gives out 650ma, which means that in the event that you are charging a fully depleted extpack and say a 50% power left SGS2, the charging of the extpack will take FOREVER (phone first, then case).
But charging the SGS2 takes forever to begin with, so...

I'm no electrician myself...
But... about the car engine.... there are fuel governor controllers which only allow enough fuel as is needed to enter the combustion chamber...
but.... we talk of batteries... the way electrons work.... my understanding is...
flow of electrons is decided by the potential differnece available for them to travel across.. the higher the potential difference... the more electrons would flow...
So, lets say... the SGS2 has a power consumption of 100 milli-amps (based on whatver the volgtae rating is).... a 100 mah battery would run it for 1 hour... a 500 mah battery would run it for 5 and so on....
Adding a battery in parallel.... would not increase the power consumption from the original spec'd power requirement of 100 milli-amps... it'll just increase the total amperes available to run the device... so.... more ampere-hours available... hence longer hours available to run the phone
Quite simply, it is similar to leaving your phone connected to the charger... I'm sure most of do this every night for the duration of the night....
leave the phone connected to the charger... i.e.

Ars Technica has a good article on batteries. It basically says this thing should have a power button!
http://arstechnica.com/gadgets/news...-is-the-best-way-to-use-an-li-ion-battery.ars
"On the other end of the spectrum, keeping a Li-ion battery fully charged is not good for it either. This isn't because Li-ion batteries can get "overcharged" (something that people used to worry about in The Olden Days of portable computers), but a Li-ion battery that doesn't get used will suffer from capacity loss, meaning that it won't be able to hold as much charge and power your gadgets for as long. Extremely shallow discharges of only a couple percent are also not enough to keep a Li-ion battery in practice, so if you're going to pull the plug, let the battery run down for a little bit. "

I believe that the phone, like the iphone, and most laptops, don't fully throttle their devices on battery. So maybe when it's plugged in it would use more power thinking that it's tethered into the wall. I had that issue with my iPhone 4. I had a battery case for it. The phone itself could last me say, 6 hours on its 1400 mah battery. When I put the 2000 mah battery back on it, before the battery pack died, was only 5 hours. So my phone consumed 2000 mah in 5 hours, while on the internal (smaller battery) it consumed it within 6 hours. Hmm... That's not right. So, then I investigated it and while plugged in the phone went into "performance mode"
Is that at all possible on THIS phone as well? hehe.
I'm not big on the whole battery switch, so, I'm skipping this case. I wrote power skin and let's see if they release one for the SGSII. I'd love it if they did

There's also the fact that a battery directly wired to the device will always perform better per mah vs an externally mounted battery. Heat loss through the external connector, yada yada.
If you're afraid of "performance mode" (which I also think some phones have), just use SetCPU to override it, like I do.
I'm hoping PowerSkin comes up with something soon too - as a case, the ExtPack has really crappy all round protection, especially on the front (getting the SGP Glas protector because of this).

i'd go for the case only without the battery.... it looks quite dangerous...

Battery Death!

Hello XDA,
I got a nice new gnex at I/O. I've kept it stock, rooted it, etc. Battery life has had a steady decline. Here are some stats:
Jun. 28: I/O
First complete day after using device. I looked at an old screenshot. 2 hours, 46 minutes of SCREEN ON time, and a 14 hour charge-day, left me at 1%. Complete rundown. Died right after.
November 9th: Recent
Another complete rundown. 1 hour, 58 minutes of SCREEN ON time, 9 HOUR charge-day. Died.
You'll notice I've only had this device for a few months.
Thoughts? I'm interested if this happens to anyone else. I've been charging it with a low-current ADK 2.0 adapter for the past couple months to charge it. Is that a problem? I assume the device has a nice power-regulator for charging. The original samsung adapter that came with my nexus remains unopened.
Will buying a cheap battery on ebay fix it? Do samsung phones (this is my first) have that same "battery stats" stuff like other devices?
I appreciate any help. Happy Thanksgiving!
jcarrz1

you may want to think about getting yourself the 2000 mAh battery instead of cheap china pack.

wow that is really good! does that one require the back cover that's a bit thicker though?
anyone have ideas why mine died (lost longevity) so quickly?

Yeah it has a new battery door that makes it slightly thicker. You can still use most cases, worst case scenario you can use a case w/o the door, that is what I am doing with my Commuter.

Sprint was giving away the official Samsung extended 2100Mah battery for free, it came with the rear batt door also. The bulk it added was sooo minimal, it actually made the phone seem to fit into the case better. I got the battery a few days after I got the phone so I have no idea of how much more time I got versus the stock one.
I also have a Scosche USB charger that has two USB ports on it one that is 1 amp and another that is 2.1 amps.The higher amperage port is made to charge the iPad since it has a huge battery and 1 amp will take forever to charge the thing. if I charge my phone in the 2.1 amp port it will fully charge my Gnex in half the time, will it burn up my battery maybe. But I only use it if I have to go somewhere and I need my batt to charge in a hurry. Normally I use the 1 amp port. I believe the phone regulates the charge and will cut it off when it senses the battery is full.

Review of Intocircuit® Power Castle 12000mAh Portable Dual-Port External Battery Pack

This is an amazing battery with a great build quality and performance that is just out of the park!
In the box, you get the battery itself, a micro USB cable, a really nice carrying pouch, a HISCARD warranty card, and an instruction manual.
First Impressions: This is so nice! It feels so smooth and premium in your hands. The orange parts of the battery finish it off very nicely. Pressing the button to illuminate the battery percentage blew me away. It is a really bright blue LED indicator that grows on you immediately. Using it was a breeze. I simply used the supplied cable and plugged it into the battery. I then plugged that into my phone, and it was charging. I didn’t even have to press the button, it detected that the device was connected automatically.
After using this for a while, I can safely say that this is downright a great battery! It does exactly as it promises and this is a product you have to have in this day and age if you don’t already. I was able to charge up my Samsung Galaxy S3 in no time with the 2.1A port. If you ever find yourself with no place to plug in your phone and/or if your phone dies, this will be your savior. This battery is just that good, I don’t know what else to say. Intocircuit got the design, build, performance, and feeling just right! It’s a perfect battery, and I haven’t experienced any conflicts with it.
I would recommend this to anybody who is in the market for a well-priced battery that has a great build quality, feels good, and works well.
Overall, this is a great product and I highly recommend it. One of my favorite things about this battery isn’t just the metal build, but also the carrying pouch. It is a great accessory that makes this product perfect!
I was provided a unit for testing purposes and I promised to provide a completely honest and fair review.
Unfortunately, I cannot post the link to this product on Amazon because posting commercial links is forbidden, but you can find it on Amazon by searching for the product's name that is in the title of this thread. Thanks!

Just ordered one of these and am waiting for it to arrive. It's looks great and seems a bit slimmer than last year's model while having a larger capacity.

Yes, last year model (11,200 mAh) was not good. Very poor efficiency where you loose over 40% of capacity after conversion and also a poor standby time where I suspect LED display was draining the battery at high rate.
@Mon431, charge it up to 100% and set it aside for a week, and come back with a reading of remaining battery without using it to charger anything. See if it drains in standby. Also, you can try how many times you can charge a phone or a tablet with a known battery capacity off this 12000 mAh battery to see the actual capacity.

I decided to do your experiment for an extra week, just to see how it would hold up. After two weeks of not using the battery after fully charging it, the battery is still at 100%! This battery definitely has a great standby time.
