I ordered mine from OBOStore about 5 days ago for just under $9 shipped...they come straight from China so shipping will take a couple weeks.
I have heard mixed reviews about Andida, but imho its just as good as Anker

In my honest opinion Anker trump all but anything besides stock probably have an advantage. I reccomend the Anker 2 pack plus charger on Amazon personally
I can't post a link due to the fact I lurk and don't ever post apparently. I'll only you it

Anker x 2 + Charger from Amazon...

I used them with my hd2. They did not have anywhere near the claimed capacity, but were better than stock. They weren't available when I bought spare batteries, so I'm using Anker. With ICS I don't use the spare batteries much anyway.
Sent from my HTC View somewhere in LALA land

I've read numerous reports about the Anker displaying inaccurate % after a full charge and such. Guess I'll give it a shot myself and order one. Anything better than the stock battery is preferred.
Sent from my HTC Ruby

Inaccurate % was due the different voltage in batteries. All of ankers batteries out there for our phone are 3.7V and we use a 3.8V. There used to be a very extensive report on anker and another company somewhere in our forums but I can't find it.
Just to be clear there's nothing wrong with using a undervolted battery as long as you aren't undervolting trough setCPU or any other similar program. It will have a negative effect on batter life and phone preformance.

I've always wondered if the Amaze phone hardware charges to 3.8, and may have problems with overcharging the Anker. I have always charged my Ankers via external charger.

O.K. so I shouldn't be charging it in the phone at all? or just not to 100%? because it seems whenever I do charge it to 100% as soon as I take it off it drops to 96% almost instantly... but I usually get 12-14hrs of med-heavy usage... and usually at least 6hrs of extreme usage... so I think it does have capacity... wish I had done a little more research before buying though, would have bought a 3.8V battery...

No, I have actually been charging it in my phone these days. It started when I forgot I had swapped out my OEM battery, and it was fine in the morning. So you can use the phone to charge.
I don't know if there are any 3.8v batteries of this size, except OEM.
EDIT: Mine drops % pretty rapidly after disconnecting the power as well.

3500mah battery woes....

So here's the deal. I bought two 3500mah batteries for $24 bucks off ebays "buy it now". They're cheap chinese 1billion made type batteries but last 36 hours. 17 avg off my 1930mah stock so worth the $25 in my eyes.
Here's my issue. I've installed cm7 beta with new battery in at %100. I've wiped stats at %100. Let it die and recharge without interruption. Wiped battery stats numerous times. Cmw and the calibration application. My issue persists. I will have the same "stats" as my stock battery but with a huge "reserve". By reserve I mean I will be at %1 for 7 hours or more. I can't be the only one.

interesting, will try that.
the odd thing is that the original battery goes dead at 3400mV also...
I wonder how these things work. Does the phone "remember" different batteries, or is it just the same "calibration file" for any battery plugged in? if that's the case, then we cannot use "spare" batteries then?

All modern lith ion batteries max out around 4200mv (anymore and they risk exploding) and are considered "empty" at 3400-3300 depending on the manufacture, if they decharge anymore they won't charge again. I'm guessing there's a calibration chip in the battery that's messed up on the Ebay batteries or something of that sort. If you were to but an OEM battery the battery life gauge works just fine.
Think of it like this mV is how full you're gas tank is in you're car 4200 full 3400 empty. Now every car can be 100% full but every car doesn't have the same size tank or Mah in this case. So basically you switched the gas tank on your car with a bigger one but didn't change how it reads how full your tank is so basically you need to guess by your mV.

Looking for a Rezound owner w/a thunderbolt

Looking for confirmation that the battery from the Rezound will work with the Thunderbolt. If anyone can confirm this I would greatly appreciate it.

all I can confirm is that the battery from the T-Mobile MyTouch 4G also works in the Thunderbolt(and vice-versa), just not the back covers.
also, once we know if the Rezound/Thunderbolt batteries are compatible, the back covers obviously will not be. so if you're planning on putting one of those extended batteries in the Rezound you'll be out of luck.
The Thunderbolt battery works in the Rezound, at least mine did.
Sent from my ADR6400L using XDA App
I just switched them between my Rezound and my wife's Thunderbolt. They both worked in the opposite phone. However, on the Rezound, the battery icon showed an exclamation point, like something was wrong. Phone still works though. *shrug* Back covers fit on both too.
After getting mine on Thursday I did notice the Rezound battery will fit a Thunderbolt and vise versa but in looking at the voltages the Rezound battery is a 3.8v and the Thunderbolt is a 3.7v so I would mess around with it. The voltages don't match up. But they do fit perfectly.
I ended up buying one at the VZ store. It's working but for some reason my battery is not reporting the correct level. I can't figure out why. I have cleared cache, dalvik, and battery stats (at 100%.) I even wiped and reloaded my rom. Anyone have any ideas on how to fix it?
The voltage is different I believe the capacity of the battery is read by the voltage, so if the voltage is already lower it will read a lower charge.

Thunderbolt: 3.7VDC - 1400mAh - 5.18Whr
ReZound: 3.7VDC - 1620mAh - 5.99Whr
basically, the Thunderbolt battery should work just fine... although since the 'wattage hours' on the Thunderbolt battery is lower(not to mention the 'milliamp hours'), the Thunderbolt battery isn't going to last anywhere near as long as the ReZound battery.
It's working great now. Thanks guys.
Hello, looking at what pictures I could find, the sensation XE and the evo batteries all look similar to the rezounds, any chance someone here has some lying around to test? A 1730mAH battery would be nice if it fits with back cover.
*Edit* Ahh I see there is a 1800mah for the rezound already, ill just go with this!

Ok, so weird. This is my Rezound battery:
My buddy bought a Rezound at Best Buy just a few hours before me, though, and his has the 3.7v batt. So strange. Obviously, the Rezound is able to cope with either voltage, though.

Battery voltage is not a constant. A single cell lithium ion battery is rated at 3.7 volts. The 3.8 volts on your pack is probably a miss-label. At full charge, a single cell lithium ion battery will be around 4.2 volts. It will go down from there to a pre-determined low cutoff to protect the cell. If you can find a widget or app that shows battery voltage, you will see what I mean. I've never run my phone down to see what level it shuts off at but I suspect it to be somewhere around 3200 - 3000 mV. As someone who races RC Cars with lithium ion batteries, I can tell you that we usually use 3 volts for a low cutoff to prevent damage to the cells.

Yeah, I don't put too much stock in it. I measure close to 4.2v at full charge, but never checked the low voltage cutoff. I used to race RC but that was before LiIon rolled around!

3030 MAh Gold Battery

Hey guys,
Some of you might've seen this on the N7000 threads,
This is to confirm that the same battery is sold to Canada on Ebay, and it works pretty well on the i717.
The battery is called the "3030mAH High Capacity Gold Battery"

I do not have the test results yet from Battery Monitor Widget, because I don't really know how to do a full MAh test. Maybe someone can enlighten me on this.
Through everyday use however, it does seem to give me an extra 10-15% on the battery (which is around one hour for me).
For those who are interested, order it from this Ebayer:
http://www.ebay.com/itm/270942481442?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649
Ps. The Charger is SLOW though, I usually use it on the other batteries overnight.
Have you had a chance to get numbers from battery widget?

I have this one and t he 3080 one. Both work ok- not much more lasting than stock. I get 35% by end of the day remaining with moderate use, push email, 10 widgets, and 14 alarms.
I have the 3000mah version from these guys and these are just 2500mah batteries repackaged. I thought that I was getting more battery life too at first, that's mostly because you are trying to justify the purchase subconsciously, but they aren't any bigger and are actually lighter than the stock battery
They do seem like good quality batteries, just not any longer lasting than stock unfortunately.
If it were possible to get a longer lasting battery in this phone that was the same size as the 2500mah one you can be assured Samsung would be selling it as an accessory for $50, people would gladly pay for it... Samsung wouldn't miss out on making extra money on accessories...

If it truly is a larger battery then it should take at least 30 minutes longer (using the 1 amp wall charger) to charge from dead to full.... But I found that my charge times didn't change any appreciable amount, so the capacity isn't any different...
Here is some times taken when i first received the battery.

No not yet, haven't found the procedure to measure actual mAH in the battery yet. I have tried charging to 100% and draining it to 1%, but it doesn't show the information automatically.
so its not really 3030mah ?????????? thats been proven?

It doesn't take any longer to charge from empty than the stock battery does, so Its not any larger. My charge times were within 10 minutes of each other when comparing to stock.
Ebay batteries that are the exact same dimensions as stock but claim to deliver more capacity than the stock battery are pretty much always lying about capacity. Its all marketing. If the battery was heavier than stock I might say it could deliver more capacity, but they are usually lighter.
There is an app on the market called battery drain...
https://play.google.com/store/apps/...fender&feature=nav_result#?t=W251bGwsMSwyLDNd
Be careful using this, it will drain the battery VERY fast, potentially heating up the battery to beyond safe temparatures. DONT SELECT EVERY OPTION!!!
Here are the options you can select to have it do all at once.
-Turns on Permanent Vibration
-Enables Wifi Send Data
-Constantly Max Loads CPU
-Sets Screen Brightness to Maximum
-Enables GPS Location Services and Constantly asks Device to Refresh Position
-Turns on Camera Flash
-Turns on Bluetooth and Constantly Scans for New Devices
I would also grab battery monitor widget pro by 3C (the paid version is $4) or another battery app that has detailed logging.
https://play.google.com/store/apps/...ult#?t=W251bGwsMSwyLDEsImNjYzcxLmJtdy5wcm8iXQ..
Consistency is the key, what I would do is power down the phone and let the battery completely charge (use the volume rockers to turn the screen occasionally to see the battery charge level, its fully charged when there is a 100% shown inside the green battery).
Set the battery logging app and the battery drain apps either on the lockscreen if you have something like widget locker or set them on the first homescreen that appears on an initial boot so you can access them quickly.
Then unplug the phone, note the current time (open the clock on your PC for seconds), power the phone up, wait a set amount of time (say 1 minute from when you initially turn the phone on) and launch the battery drain app, turn on maybe 4-5 of the options (dont use all of them, you dont want to damage the battery), say max screen brightness, camera flash, wifi, bluetooth, & GPS and wait til the battery dies and note the time when it dies (shouldnt take more than 1 hour).
You can test each battery this way (make sure you pick the same options in the battery drain app) and if you have an app doing battery logging, you can pull up the stats after the phone dies and you plug in the charger to reboot it.
Its also key that nothing changes (dont install any new apps or remove any apps) between testing. What most testers do is factory reset the phone, leave all the settings at stock and install only the apps they need for testing. This might be a bit extreme, the key tho is to have consistency.
Using both batteries and testing them in this fashion would give more information rather than anecdotal. However, I can understand that it is a time consuming process.

Anyone know of an app that measures the battery's mAh?
I have tried battery monitor by 3c, but I don't think it works completely with HTC phones.
Either it keeps saying measurement requires 40% or larger charging cycle or it reports something crazy..

I know this thread is old. But in case anyone still interested, you can find it by looking at your physical battery(if you have a removal battery of course)
Look for Wh and V printed on the battery.
mAh = Wh × 1000 / V
Example:
Samsung Galaxy S3: 3.8 V 7.98 Wh
7.98Wh × 1000 / 3.8V = 2100mAh
I think he meant how much Mah or capacity is actually left on the battery. You can do this in Linux, but not sure about Windows or Android. For example my laptop battery is rated at 4400mah, but the Lubuntu tool tells me max capacity is only 2920mah now.
Well, I think what he needs is to test the battery capacity, as we know lot of 3rd party battery claim higher capacity than it does.
The way to do this correctly by measuring the battery using mAH meter.
But if you want to do it by software, I think you can use this
https://play.google.com/store/apps/details?id=ru.NanoDinamics.NovaTester
But, I'm not sure either this will give you an accurate result.

Gonna check it, but as my battery is about 3 years and some months old (Galaxy S2), I won't have any way to know if the result is OK.
Thanks for sharing the app!!
Well, after running the full test, it showed that my battery's real capacity is a hilarious amount of 750mAh, not even one Ampere per hour. I estimate about 1800 charging cycles

Okay i will
now im using an 1 year old mugen extended battery (3200mah), i will put this batt tot the test too
overall im still happy with the S2, its far from ready to sent to retirement just yet lol
okay the test is started
Here it is and im very suprised, +- 400mAh loss in a period of 3 years
here is the result of the test of the Mugen 3200mAh battery.
(bought it used a year ago, so i dont know how long it was used before i bought it).
And i did my research, this battery has been tested (new) and give arround +- 2400mAh in real-time even though Mugen claiming its 3200mAh
overall +- 250mAh loss, im very pleased with the performance
btw for informative purposes the screen was at full brightness in both tests

[Q] All about batteries, which do you prefer?

Back-up Battery(i.e-power banks,power tube,battery cases,etc)

Removable Battery(i.e-Hyperion) remove and replace
Which do you prefer guys? any pros and cons.
ide go for the hyperion, its pretty much the same as genuine batteries if not then better
ive seen reviews that hyperion is one of the best and affordable also...
hope i helped
I've read that often removing the battery and placing another one will make the battery "pins" in the phone loose and will result.... don't remember exactly but negative effects on the battery
is that true?

well im not to sure about your question but ive heard that if you keep on charging the battery without fully draining it first gives you less battery life over time for the phone.
hope i am of help in some way

As far I know, it's quite the opposite. Li-ion batteries do not have "memory effect". In fact, letting the battery fully discharge wastes a life cycle. However, it is advisable after 20/30 charges, to perform fully discharge/charge to re-calibrate the measurements. Some says that if battery stays between 40% and 60% of charge is the ideal (due to factors such as temperature, etc.).
I don't know if to keep changing batteries may affect the pins. But as long you keep using the batteries regularly its fine. Just don't let your batteries unused for a long time.
Thanks both, but if you were to buy one which would you choose?

I don't trust 3rd party battery manufacturers anymore. I bought a couple Hyperion batteries with my Note. The batteries were supposed to be 2600 mah but it turns out they were really 1500. I have also had this same problem with another manufacturer that everyone said was good. I don't trust them anymore. I bought a genuine Samsung battery. One other thing to note, if you want to use NFC, you will need the Samsung battery.

I don't really use NFC that much, I only know a few people that have s3.
so that problem of the hyperion was the 2600 mAh turns out to be 1500 mAh? how did you know exactly? also did the battery(hyperion) did negative effects on your note?

I found out because several people on various boards pulled the original label on the battery and saw the real mah size. This seems to be a problem with a lot of 3rd party batteries. You really do get what you pay for. The battery did work but did not last anywhere as long as the original. I also do not believe the batteries harmed my phone in any way.
Well you got 2 pcs of that hyperion batt right? so that makes equals to 1 good battery lol
I've also gave up hope on 3rd party batteries after a lot of testing and analysing with a real battery analyzer. For example, the genuine cell in a SGN specified to 1750mAh measured 1690mAh which is well within margins. The same for genuine Nokia cells. A well known 3rd party battery manufacturer has this "super mega xl" cell specified to x000mAh but turned out just at x300mAh which is really bad. The internal resistance also appears to be worse on most 3rd party cells.
