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:

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...

Hi all,
my first original htc s620 battery gone, some time ago i buyed chinese battery (now gone). This is ONLY A TEST TO TRY RETRIEVE A CRAZY LI-ON BATTERY
(i mean a battery that not hold a charge).
The lithium polymer batteries suffers high temperatures. Reading around i discover exist a way to TRY in retrieve a Li-on Battery. I'm testing it and soon we will if it work or not.
I do not assume liability for damage caused by this method. This method can be easily found online. Remember that it can be very dangerous to experiment with lithium batteries.
Ok, im testing it so:
1/ Wait until your device turns off (due to ended battery);
2/ put the battery in an airtight container and place it in a freezer for 2 hours (more or less);
3/ remove the battery from the freezer and wait for it to come back naturally itself at room temperature (so keep it away from heat sources) , it can takes about 1 hour
4/ put battery on your device and recharge it for twice the normal time ( more or less 4 hours). Recharge the battery while holding the device OFF
5/ after a long charge, the battery will become usually a little hot . So remove from device , wait until it returns itself to normal temperature and then put it back in the freezer for another 2 hours.
6/ remove again from freezer, wait it back itself at normal temperature (about 1 hour) . Then put it in the device and test how long it works this time
It might recover some charge because seems low temperature (around and not too much under 0°) stabilizes cells.
ALWAYS REMEMBER TO WAIT FOR THE BATTERY RETURNS ITSELF AT NORMAL TEMPERATURE . BE SURE THE BATTERY IS NOT SUFFERING FOR FAST CHANGES IN TEMPERATURE ( IT CAN BE DANGEROUS) .THIS TEST CAN BE DONE ONLY USING A LI-ON BATTERY (ABSOLUTELY NOT ON A NICKEL BATTERY)
I'm testing it . I'm curious to know if this method can be useful.
In the next days i will put the result.
If you look for a method to measure the capacity accurately, look at my signature. Looking forward to read if there is any success (I doubt it).

ok this is the result. I've found some changes.
After freezer treatment, seems all my two battery maintain better ( little more time) their charge segments. But the batteries did not lose the effect of "virtual memory " . This means they continue to not be fully charged, infact the device goes off several times before the it can no longer switched on. BUT as i said before, the segments charging now last longer than before.
So this method lies partially. You absolutely cannot fully recover a worn battery but...surely the ice temperature make some little changes in your battery.
i'm buying a new "extra long" chinese battery of 2200mA
@tobbie : do you think a new battery must be charged immediately ( when it will arrives) or it's better if i use the partial charge i will found on it ( before recharge)?
My experience with Chinese batteries is very bad. You will get a labeled block of bull**** not worth the postage. I have tested several in my efforts to find the best one and they ALL (no exception) perform worse than the original ones. They never keep the promise they make on the capacity.
If ever possible go for the original batteries, next best is quality replacement parts (whatever that is...) or try your luck with cheap Chinese ones if you don't care about the few bucks.
Good thing is that you have a reference method for comparison, so I would be glad to get your battery rundown to judge upon it.
Li-Ion batteries have no training phase and also no wear depending on charge cycles (unless deep discharged). Look up my thread on battery capacity measurement, some interesting links there.

Repair battery.
I have the original batteries in both my S620's, try this, when the phone starts switching off after a shorter period, ie less than a day, when it switches off switch the phone back on until it again switches off, repeat this until it won't switch on. Recharge and repeat the process, you should find the battery works like new, mine did.

...another miracle in batteries life
I only trust measured proof. Can you supply this, e.g. a tracked run-down like suggested in the measurement thread in my signature?
There are rumors (no proof) that devices "learn" about the battery and they can be reset in learning by doing as you suggested. I have not seen anything like this happen in the devices that I own. Charging when device is switched off is done by HW only (the chip) and the shutdown is purely guided by measured voltage. No space or logic for any sophisticated memory...
I don't care if you believe me, I only wanted to help, if you don't believe it - tough. All my phones work with original batteries, believe it or not.
I don't argue that original batteries work (they do best for me as well). My doubt is about the procedure to "train" the device to recognize batteries better and consequently deliver a better duty cycle after that.
My experiences are different. A "dead" battery stays as "dead" no matter what you do to it:
deep discharge (as much as possible) + recharge: no change
freezer treatment: no change
Everyone may try himself - no harm expected. My proposal just is to put the "improvement feeling" on a metric base, so just to measure it.
The problem with subjective observation is that your normal use patterns are so much depending on the environment (location, movement, device use) that they are never so identical that you can compare one week of use with another.
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.

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.
You can find the URL here:

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.

Well that isn't so bad as batteries aren't expensive anymore. Just 12€ or so.
this would probably work for any phone not just HTC but you are basically tricking the phone into over charging the battery which weakens the lifespan of the battery, all for a few extra minutes of battery life, not worth it.
Yea, this is terrible, destructive, downright negligent advice.
Yes, not good. I work with battery chargers and Li battery characteristics and you will actually age and get less capability very shorty doing this so you won't get those extra charge lengths for long (you do this maybe 20 times and you will in worse shape after that than someone just doing normal charge).

Hah, this coming from the guy that advocated doing that.
u understand yr cause of concern....this will not wear out the battery faster...unless batteries that u use do not have rapid discharge capabilities eg. Iphone poly battery.
In this case it will wear out the battery faster
basically the battery wears out the same rate as all other batteries...
the cells degradation occurs each time u charge...
and modern batteries do not overcharge...some like HTC batteries will discharge rapidly to 80%
basically u are just charging the remainder of the cells
Quote me where I advocated doing that.
Please do a post search on me and you'll see that we've had this discussion in the Vibrant forums already, where I stated it was dangrous.
What I do advocate is keeping your phone on a charger whenever possible (bump charging).
I do not advocate tricking the phone into overcharging. No one wants a battery to blow up in their face, you know...
Or maybe you're confusing a confirmation of that working with an advocation that it's okay to do it? In that case, your school district obviously failed. It has nothing to do with what I stated on these forums or otherwise.

The issue doesn't come from fear of wearing the battery down. It comes from fear of a device blowing up or catching fire on someone who is overcharging it. There is enough evidence even on youtube of batteries going haywire. This is a risky tactic to achieve basically no noticeable increase in battery life.
The HD7 in a high 3G coverage are (full bars, 3+ Mbps download speeds) gets ~4 hours of battery life under heavy use (mostly browsing, reading Pulse Reader Articles, and checking Social Networks now and then - no Music or video - so really it's only heavy in the fact that the phone didn't sleep a lot, should be called more moderate if anything... Phone shows 67% battery left with 2 hours projected uptime). Overcharging your battery won't change that terrible battery life into good battery life. It'll only make it 5 minutes less terrible.

There is enough evidence even on youtube of batteries going haywire. This is a risky tactic to achieve basically no noticeable increase in battery life.
The HD7 in a high 3G coverage are (full bars, 3+ Mbps download speeds) gets ~4 hours of battery life under heavy use (mostly browsing, reading Pulse Reader Articles, and checking Social Networks now and then - no Music or video - so really it's only heavy in the fact that the phone didn't sleep a lot, should be called more moderate if anything... Phone shows 67% battery left with 2 hours projected uptime). Overcharging your battery won't change that terrible battery life into good battery life. It'll only make it 5 minutes less terrible.

they can only blow up by removing their circuit protection
If you say so
Batteries still overheat, catch fire, and in rare cases blow up. Overcharging them is risky. Yes, it's rare, but would you want to be that 1 in 10,000 case where it does do that, in your pocket or something?

u understand yr cause of concern....this will not wear out the battery faster...unless batteries that u use do not have rapid discharge capabilities eg. Iphone poly battery.
In this case it will wear out the battery faster
basically the battery wears out the same rate as all other batteries...
the cells degradation occurs each time u charge...
and modern batteries do not overcharge...some like HTC batteries will discharge rapidly to 80%
basically u are just charging the remainder of the cells

1.) This will wear out battery faster, why? You are fooling the sensor to charge the battery more.
2.) You can overcharge batteries, don´t know where you found out you can´t. The only good thing is, that the modern phones cut out charing when battery is full and is running on charger (to keed battery charged).
3.) My battery is not rapidly discharged to 80%, I charge it up 100%, and it stays there, when your battery quickly discharges to 80%, that´s your problem from experimenting with charging.
Again - STOP TELLING PEOPLE TO KILL THEIR BATTERIES, I told you numerous times, you always act like you invented something, you didn´t, modern batteries use more advanced techniques to help them prevent from being damaged, overcharged, deeply discharged, etc. So stop telling people how to fool these sensor and stress the battery.
Thank you
Hey guys,
I wouldn't recommend this advice as well.
As for me, I bought a second battery 1600mAh.
I use this battery as my primary battery, now I get 30-40% more time on my HTC HD7, and actually can go a whole day with 2G only. While before the phone dies before the end of the day.
While my original battery I keep fully charged sleeping in my wallet, so if the 1600mAh is fully depleted and I'm away from a charging station, I quickly replace and resume working on my phone. This method gets me through a whole day of work+games+social.
I don't remember the price of the 1600 battery but it costed me 10-15 Euros I think.
I believe this is most practical than carrying an attached battery to your phone which results in a gigantic phone in your hands. Or overcharging the OEM battery and probability of having it blow up.
What do you think guys?

Actually maybe edited and left as a warning for anyone who searches for this method or thinks of doing this method.

may u give mroe details about the 1600 mah battery?
brand size and where u bought it??
This is the one I bought:
http://www.ebay.com/itm/1600MAH-HIGH-CAPACITY-BATTERY-REPLACEMENT-HTC-HD7-/130497652694?pt=LH_DefaultDomain_3&hash=item1e624427d6#ht_2154wt_1139
I found similar hits on ebay USA, but the writing on the battery is different (Even though they are the same brand).
You can search ebay yourself for a similar looking battery to the one I posted.

does it really last longer???
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.

Good idea @vectron, I've started the standby experiment like you mentioned. It's been one day and so far, it is still at 100%.

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.
Hi guys.. I'm thinking about buying this battery case for the mate 20X. It says it has a battery capacity of 6000 mah. Does this mean that this capacity is separate from the 5000 mah the phone has, so that I get a combined 11000 mah?
Has anyone here bought it? Is it worth buying?

Just some helpful advice from a recovered extended battery case addict. In the early days when phones didn't have quick charge and we're about 25-50% smaller, I always bought my phones based on the support of manufacturers making extended battery cases for it. As the phone market matured, batteries became bigger and locked in, I noticed that my power consumption was less likely to hit the max of the stock battery. The weights of the phones increased as well and I noticed a chronic pain on my pinky. This combined with the fact that the extended battery cases didn't have quick charge, rapid charge, super charge, it whatever "special" charge came with the phone, as well as a key missing feature of charge passthrough, caused me to drop the extended battery madness. I expect you to come to this conclusion on your own, because like me, you won't be convinced of extended battery cases being a bad joke until you see it for yourself. Make sure there is a good return policy.

Hi techronico,
Appreciate the reply. As far as quick charge goes that will damage the battery in the case the same way it can damage the battery in the phone. This is why I have a slow charger to charge my phone healthily instead of risking permanently frying the phone's battery which will shorten its life. I'm no fan of quick charge.
Regarding pass-through the seller confirms that the power case is equipped with heat, overpower and temp protections. What do you think?
Just to be sure the power case doesnt degrade the phone battery do you think its best to charge the phone case and phone separately and not connected together?
Looking forward to your reply.
I would never spend money on anything like that since I can get 2 days on a single charge on my 20X. All the new phones now use LiPo batteries (the same cell type used in Tesla cars) and have no problems with quick charging and don't exhibit memory as it's predecessor battery types used to have.

Hi ben,
I'm not talking about quick charging. I love slow charging.
Anyway I get 3 days from my 20X. The problem is when I have 30% left it starts to drain like crazy. Thats the reason for wanting the battery case.
Did you get the battery case in the end? They are available very cheaply now from Aliexpress. I don't really have a problem with battery life but am thinking it might be a nice gadget to have
