My one year old Jasjar has started dying when the battery has 60-70% power remaining. Looking at the other threads here it sounds like the solution is to replace the battery. I'm thinking I want to get one of the extended batteries, but I don't want to increase the size of the Jasjar by too much. I've discovered that there are quite a few extended battery options, and it looks like they add between about .5cm and 1cm, but many stores don't mention how much the batteries add. Additionally, I've seen some posts that suggest that some of the cheaper batteries don't correctly report their remaining charge status and the Jasjar simply reports 100% charged no matter how much power is remaining.
If any of you have one of the extended batteries, can you please give me the following information:
1 - mA capacity of battery
2 - size increase when battery is installed
3 - whether the built in power meter works correctly with the battery
4 - where the battery was purchased
Thanks much,
Brett
1 - mA capacity of battery (3800mAh)
2 - size increase when battery is installed (extra 9mm)
3 - whether the built in power meter works correctly with the battery (works correctly)
4 - where the battery was purchased (expansys)
enjoy!

Are you sure it does not increase the thickness? Because from what I can see, IT DOES INCREASE THE THICKNESS, that is why there is a cover included. You are referring to this: http://www.mobixhk.com/product_info.php?products_id=122&osCsid=9e76ca40892bbff9e68cb6d07a6c7297
What is sad is it is only 2200 as compared to the other extended batteries out there which also increases the thickness, and they have 3200 and 4800 capacities. So why should we settle for something that also increases the thickness with a lesser capacity? I'd rather go for the higher capacity battery, but this is just me of course.
pictures of my extended battery
Here are a few pictures of my extended battery.I have charged it only 4 times since i have purchased the battery.Although im not a power user as most,it does the trick!!!

that's the 3800mAh/9mm one? doesn't look anything like mine.
So my roommate got an EVO, and i put his battery, which says 1500 maH (where our stock battery is 1300 maH..) and put it in my phone. Battery Monitor Widget says it's capacity is 1300, and not the 1500 it states on the battery. I also ordered one of the black batteries off ebay, or amazon (Iforget), the one's for 6 bucks shipped...They state 1500 also, but show up as only 1300. I don't think that the battery monitor is lying, because when i put in my 2150, it shows 2150. Anyone else notice this? What perplexes me is the "1500" batteries ARE a bit bulkier than the the OEM 1300, so you'd think they actually ARE larger in capacity...maybe this has been covered before, i don't know..
Really? NO ONE has any input?
Battery monitor widget defaults to 1500 on my EVO. I haven't tried any other battery types though.
1500 is what is says, right?
My bet is that program isn't pulling that bit of information from the battery itself, rather than a database that shows standard specification of the phone.
Well I arrived home from some boxing day shopping today to a package in the mail from ECell in England.
Sound like a similar tale from two weeks ago? Yup!
It's another battery review and test.
Second week results of my previous test of the Cameron Sino Technology 2200 mAh Lithium Ion "FAT" Battery are now posted in the review thread so check those out as well.
so back to my initial thoughts.
The battery came encased in a simple thin plastic deliver bag with no protection around the battery. Sorry ECell but taking the slow boat from China (Literally) I would expect a little more protection. So...5 points off for shipping style.
What was fairly impressive was the time to ship from England to Canada less the days the post was closed for weekends and holidays totalled 7 business days. So...5 points back for delivery as promised.
The battery is currently doing it's initial charge on the universal charger before I pop it in, clear my stats and start testing.
The first thing I can say about it is...Wow...Shiny. I like shiny things.
Aesthetics aside, it fits properly, nice and snug under the original rear housing. I will have to get used to a "thin" phone again at least for a while...
Ok. Prediction time...
I don't see this battery making 2430 mAh but who knows. Li-Pol is different stuff and hopefully it's what slim dreams are made of.
For $17.00 US, including shipping, I won't complain if it hits 1700-1800 mAh but here's hoping.
Attached are some photos of the HTC Stock, The Cameron Sino Technology and the ECell batteries side by each and parallel for your enjoyment and viewing pleasure. Notice the dimensional similarities between the stock and the ECell.
I don't have my scales of power and wisdom handy so I was unable to weigh the batteries but it feels slightly lighter to the touch but not by a considerable amount.
Right now it is at 3.85 volts and rising and very cool to the touch.
Once it's done it's initial charge I am going to run it dry under normal use a few times to calibrate the battery and post the results for average longevity, coolness to the touch during use, charging, and charge while using.
I will also post the calibrated mAh reading as well as any temperature fluctuations, etc.
Stay tuned.
Usage and test results...
2011-12-31:
-Battery took 4 hours to charge up to 4.218 volts
-Estimated full from empty AC charge is 4.5 hours
-No heat generation to speak of during charging or use so far.
2012-01-02:
-Battery has been charged and fully discharged 3 times now. Reset all stats and running an Antutu Battery Test on it that I will also run on the stock and CS 2200 mAh to have some comparisons that mean something.
Testing setup is as follows:
-Same phone with CM7.2 overclocked to 806 mhz to speed up the testing process for all three batteries
-Batteries all conditioned and then charged for 8 hours prior to testing
-No changing of configured apps, services, etc on phone during testing
-batterystats.bin and Battery Monitor Pro history is wiped between batteries
-Wifi and data turned off so the phone does essentially nothing
-Antutu stops phone from locking, dimming, downclocking etc. so it's basically running all out for the entire duration
-No one seems to know what the scores are or how they relate to anyone else but I figure they will relate to each other.
-Once test is complete run Antutu again to run the battery down to 1% for shutdown and get final burn time results from Battery Monitor Pro

Final Results For ECell Gold, HTC Stock, and Cameron Sino:
-3 Hours and 44 Minutes For HTC Stock Battery
-4 Hours and 19 Minutes For ECell Gold Battery
-7 Hours and 35 Minutes For Cameron Sino Battery
-The ECell Gold, at 13.34% more capacity than the HTC Stock battery, comes in at far less than it's advertised 2430 mAh.
-The Cameron Sino, at 50.52% more capacity than the HTC Stock battery, comes in at more than it's advertised capacity of 2200 mAh
The Conclusion:
You can't make a silk purse out of a sow's ear and you can't cheat physics.
Applying the same battery technology you can really only expect marginal performance gains in the same form factor as is shown with the underachievement of the ECell Gold compared to it's advertised capacity.
There were no surprises here.
Double the form factor brought double the capacity. If you're cool with a "Fat Phone", the Cameron Sino Technology 2200 mAh battery lives up to it's expectations and puts some reality back into things. You get a very high capacity battery at a very reasonable $22.00 US
In it's own right the ECell Gold 2430 mAh is a great idea for a cheap and higher capacity replacement battery and that's really the positive in that storyline.
The price is right for a slim replacement battery but they need to stop the gimmickry and advertise it for what it is.
False hope is NOT better than no hope.

There's my current widget log file for my 2430mah Gold battery.
I can't get the capacity calculator to run. But those times were taken every 10 seconds from 1% to 100% and back down to 1% if you want to run my data.
It should be noted that the phone was in standby mode minus about 20 texts...

That's what I call public service!
A user that really cares about directing others towards a smart buy.
Respect to d33ps1x for taking this matter so seriously.
I'm curious about your results after the first 3-4 charge/discharge cycles.
I always ignore the first cycle, no matter what battery I use.
Batteries are in stock too long before reaching our hands and their cells need to be "awaken" or electrically stimulated properly.
This will only happen after some serious charges and discharges.
I personally recommend that the first charge is never less than 8 hours long (sometimes I extend it to 12 hours).
By my experiences it does make a difference, even if the battery status led tells you the battery is already full after 3 or 4 hours charging.
Thanks for the public service and I wish you good luck with your experiences.
Never underestimate the first 3-4 charge cycle rule that some known battery manufacturers recommend. Mugen Power for example almost says that your battery will only be ready for use after the 4th or 5th complete charge and discharge...
First burn test results for ECell Gold 2430 mAh battery are here!
See this post for test results...
Now burn testing stock battery for comparision.
Decided to formalize the testing a bit more as terms like "under moderate useage", etc, are pretty well useless. Spent the night reading other reviews of this battery for other phones and no one had even a semi formal test in place. Just a lot of guestimates and subjective analysis.
I am going to compare this ECell Gold battery to an HTC Stock 1230 mAh and a Cameron Sino Technologies 2200 mAh doublesize "fat phone" and provide comparison based results from a common setup in a fairly static environment.
Enjoy the first set of results!

ECell On Ebay.
If you look at it as a $20.00 replacement battery it's a deal compared to a stock cell at $45.00 but definitely far removed from it's claimed capacity.
The final results are in...
And it comes as little surprise.
The three way head to head comparison of the HTC Stock 1230 mAh, the ECell Gold 2430 mAh, and the Cameron Sino Technology 2200 mAh batteries is finally over after a lot of conditioning battery cells and a final long night and day of burn testing.
Read the results here.
I'll buy this battery ASAP at 7:00 am tomorow thanks for reviewing it.

As an update. After cycling it for a while now with full to empty to full cycles it is averaging out at 1503 mAh measured which is as good as a muygen. (sp) at $50.00
With my usage pattern, which is moderate to high, I am getting an average of 1 day 4 hours out of it per use.
It's holding it max millivolts just fine as well.
The discharge cycle is very predictable with no sudden drops throughout the cycle. As you can see when I first use it after a charge cycle there is a steeper drop as I am checking forums, sms, calling, etc.
This sounds promising but I want to make sure...
Unlike the big battery which needs a special back for the phone and only fits the smaller Wildfire S not the larger one like my Virgin Mobile (CDMA) this is just a regular sized battery so I should be able to use it, correct?

Same thing happen to me, the battery for a gsm will fit a cdma and vice versa, but the backdoor will only work with gsm, I bought a Cameron Sino for my virgin mobile and wad disapointed that it didn't work, battery fits but not the case, the cdma has a weird desing, sort of a lip, making a extended cover for cdma phone probaly won't happen because of the way its designed

Is this the ecell gold? The same one that logged 652? I read the whole review but am I missing something? Why the high jump in capacity? Is it just more cycles, giving it a better capacity, or am I missing something else obvious. If it does 1503 that's a big increase over the stock battery ya?
BTW, thanks for taking the time to share all the info
Ps, are the test scores not in mAh? Maybe that's what I'm missing. I'll go read again

Indeed, it's very suspect. Item description reads:
Rechargeable Battery
* Quantity: 1
* Stay connected with your family and friends by getting extra battery power today!
* This replacement battery has an integrated microchip that prevents overcharging and lengthens battery life.
* Best replacement for the original battery with comparable standby and talk time.
* Great bargain with excellent quality guaranteed!
* Type: Generic / Aftermarket
* Cell type: Lithium Ion
* Voltage: 3.7V
Capacity :2500mAh

So if the capacity is 2500mAh compared to 1650mAh for the stock battery, why are the standby and talk times comparable, instead of vastly superior.
it seems the battery doesn't fit inside s2 !see the comments in feedback section of the seller
So the conclusion is: don't buy this battery!
this is because some people having t'mobile version gs2 bought this battery that is for international gs2 only.
Ok guys here's the real manufacturer page of the Momax X-level battery. Same specs as stock. Not better

yes, i couldn't find the 2500 version on their website

Any Li-ion battery the same size as the original is going to be more or less the same capacity, however there are many sellers who simply upgrade the label and charge more. This has turned into a bit of an arms-race where every seller feels he has to try and out-do the competition's outrageous claims. I've seen the same batteries advertised as 1650mA, 1850mA, 2000mA, 2200mA and now this guy's just trumped that.
When you complain that it doesn't last any longer than the standard battery you'll no doubt be told you have to go through umpteen discharge/charge cycles before it is at full capacity. This is also BS of course.
These are probably perfectly good 1650mA batteries, just don't get conned into paying more for a bigger number on the label.
This batt is fake, I had to buy one to believe it. I used battery monitor app to get the infor about its capacity and it says its 1650!!! Not 2500
don't buy!
I bought two pieces but same the original battery
not need for me...
One good solution for people looking for a greater capacity battery for the SG2 is the Anker at 1900mAh. I have it one year so far, and after hundreds of charging cycles it is still as good as it was the first time. Sorry for the off-topic, however not very often I have bought such a reliable non-brand product. Between 1650 and 1900 the small difference is, that the phone will make it through the day with a moderate use, because for heavy use not even the 2500 is enough....:good:
The opinions below are based on my experience, training and the tests I carried out on the purchased batteries. I am not affiliated to or employed by any battery or phone manufacturer.
I will be happy to retest and add to this report should any supplier or manufacturer believe that I have tested faulty items and are prepared to supply me with another/others to test. The additional information will be added honestly however it tests.
Tests based on a rooted and optimised version of the official 2.3 build of the HTC desire with a standard htc desire 1A charger.
Utilities used included:
Battery monitor widget pro
Antutu battery test
The reference battery is a two year old original HTC battery which is well used but still in very good condition. Capacity reasonably tested and calculated at around 1180 - 1250mAh of the original rated 1400mAh. Given normal projected losses for li-ion batteries this seemed high for a 18-24 month old battery but as other ratings are relative to this, the other estimates should be equally on the high side if anything.
A took great care to fully charge/cycle the new batteries as described by the sellers, and did a full calibrating charge cycle on the original before rating it. Battery stats were cleared for testing as each battery was tested.
Various tests were carried out including using battery monitor widget pro to analyse any different usage/performance and estimate power of each battery in addition to using original as benchmark.
SUMMARY RESULTS (mAh accuracy expected to be +/- 15%)
Antutu test scores. Note these do not define a power rating, only relative benchmarks on the same phone in the same situation. The capacities stated result from the tests with battery monitor widget pro and compared to the confident rating of the original.
*****************************************************************************************************************
2 year old original HTC battery claimed 1400mAh - tested 495 (approx 1200mAh)
New Cameron Sino (in loose packaging) claimed 2400mAh - tested 773 (approx 1900mAh)
New Bilitong gold in original packaging claimed 1650mAh - tested 356 (approx 850mAh)
*****************************************************************************************************************
The Good
========
The Cameron Sino tested is the first chinese battery I have tested which actually gives more (around 50% more) capacity than the good condition 2 year old original. This equates to somewhere between 1800-2000mAh for this battery. This does result in testing to a 50% longer phone life in the same use.
Its available very cheap
The large case back needed by these large batteries and as supplied by the Amazon seller is a good fit, seems good quality. Although effectively doubles the thickness of the phone is easy to hold unlike the reports of some no brand large batteries and larger covers with 'quick break' clips. It actually seems easier to hold to me than in the phones 'skinny' form. It of course feels significantly heavier.
The Bad - some seem very serious
================================
There is some impact on the quality of pictures taken by the deep recessed slots the pictures and flash have to pass through.
The large battery does seem to move some with a bit of a clunck felt which should be easily addressable with a small cushion pad added to the inside of the case.
The Cameron Sino battery I tested (like the bilitongs) does not seem to have proper (or at least working) control and protection electronics, in that neither the voltage or the battery temperature is correctly reported to the phone. Both report a fixed voltage of 3923mV and a relatively fixed 24.x temperature even when the phone is noticeably hot to the touch.
Both the Cameron Sino and the Bilitongs seem unwilling to report a 100% charge. Both stick at 99% although I have seen 100% on the Cameron Sino once, which may have been a very minor phone calibration error rather than the battery actually reporting 100%.
Both the Cameron Sino and Bilitong batteries demonstrated erratic battery % left (which is all they really reported) sometimes going back up significantly after being in light use and often dropping very sharply in reasonable use (wifi and browsing with bright screen).
The original did not do this to any noticeable level, always showing consistent and accurate % remaining, and as the original also reported accurately full range battery voltage and temperature, so is in a vastly higher league in its status reporting and presumably safety.
It seems to me that in both the Cameron Sino and Billitong batteries, the proper control and protection circuitry is replaced by a something akin to a simple resistor/diode type setup which is just enough to fool the phone into actually using these batteries rather than reject them as faulty as would occur if there was nothing on these circuits.
Its worthy of note that the standbye/self-discharge rate on the none-original batteries (all) is actually higher than the original with full protection circuitry - adding to the view that there are something like low quality resistors replacing the control circuitry.
This means that I cant see how any any over or under voltage or over temperature protection is done with the 'compatible' batteries potentially increasing the risk of damage to the phone.
The Ugly?
=========
Ok with the Cameron Sino its twice as thick and a fair bit heavier. But I don't see this as a great issue. It sits nicer in the hand in my view and I'm Less likely to loose it by dropping it un-noticed.
Beauty is in the eye of the beholder
So my personal views in summary.
================================
Based on the one I received, the Cameron Sino will give 50% better capacity than a good condition 2 year old original.
Presumably the gains would be significantly less over a new original HTC battery, and more over a worn out original.
Beware of the apparent lack of protection and control, the increased weight/size and possible camera problems.
If you are using the standard phone software, you could get much better increases by installing one of the optimised versions of the HTC builds available freely from the developer forums. I gained over 50% on the usable life per charge just from installing one of these, and ensuring things like gps and wifi were switched off unless I needed them. (at the touch of an icon).
Even if you don't do this, the latest official HTC 'radio reportedly improves power use significantly over older versions.
*** Do any of these at your own risk and after properly investigating the options.
Finally, I would strongly suggest you completely avoid the Bilitong batteries just as much as the unbranded chinese batteries, which in my experience are unlikely to give much better than 850mAh (whatever they claim) when new and very quickly fade, let alone the apparent lack of proper control and protection electronics (seemingly shared by the Cameron Sino).
Gonna amend the overall view with the following:
As the Cameron battery had 2-3 times the standby/low use drain of the original battery resulting in far more battery drain overnight and when the phone is simply being carried around, the extended capacity would be of far less use to those looking for extra days of light use between charges, and would only be really effective for extending heavy use in a single day.
I have already gone back to using the old original battery.
Possibly use one of the crappy Bilitongs when using GPS in the car in a windscreen cradle as the phone can get quite hot there and I want to minimise hot use of the good battery.
