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..
Thanks in advance..

It doesn't show mAh only mV judging by the screen shots.

No, I'm looking for something to show the battery's capacity. Like for example 1520mAh.

hey i would also suggest using the battery monitor widget pro as it has settings for u to set the mAh and then it will calibrate itself accordingly

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

Everything just points to carrying a spare - that way you don't cannibalise anything, and you can either choose to stickytape it to the back of the phone for that extra-bulky feeling you're after, or put it in a bag/other pocket when you're wearing them tight jeans...
Or you could just get one of these:

$17.50 shipped gets you the battery, new cover, and a screen protector. Took about 2 weeks to get here from Singapore, but I love it.
There's tutorial about making such battery. Simply, connect two batteries in parallel: + on +, - on -, and don't connect middle terminals, these are for battery temperature. Stick batteries together and you're done!

Very true.. but the cell is alot fatter..
Wiring up 2 batteries to the same battery cache is problematic..
If i'm correct the x10 reads the amount of mA passed to the phone and uses the "rated amperage as a baseline"
Meaning that your modded battery might never make the bar..
Also battery burns hurt.. ask those poor bastards with psp 1000's that had to cut open the cell casing to hack their psp.
Correct me if i'm wrong.

Okz lol i don't have that much knowledge about battery's but thanx 4 the straight answer.
How much more battery life do you think you could get out of your x10 with your extended battery?
Well most extended batteries they try to double the capacity.
But connecting 2 batteries in parallel will work.. but can go wrong very fast.
if one of the 2 builds up a memory it may lead to severe heat and maybe even the dreaded gas purge "the battery start to leak a gas" followed by a loud pain inducing bang.
Go safe.. buy the battery.
I just don't like the look of the build quality of the last link, but it should give you alot more life.

No - don't connect them because it would double the REPORTED temperature. That means, if batteries are 27°C warm, OS would see it as 54°C.
wait a minute if a remember rightly the type of bettery used in this is a bizarre, from what i read they cant trickle charge. thats why they go from 100 to 91% and then back up if theyre left plugged in

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.

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.

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.

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.

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.

I've seen reference to a couple different batteries that should fit/work, for those looking to replace the battery for one reason or another and figured I'd consolidate things here...
http://planetfon.ru/akkumuljator-li-pol---3-7v--5000mah_l238
http://www.allbatteries.co.uk/tablet-battery-3-8v-5100mah-tml90080.html
The challenge being for some that neither of those will ship to the US (no one will internationally probably, because of our lipo shipping restrictions).
Anyone found a supplier in the states with something similar?
My main worry would be: how do we know that the replacement battery we buy from some obscure online store is any safer than the original faulty battery?

You don't. But since my old tablet's battery got bloated, I'd rather take my chances with a dubious china battery...
BTW: Anyone knows a compatible battery obtainable in Germany?
@ slideyneez: Where did you get the link to the battery from allbatteries.co.uk from?
I found a battery that someone posted that should work and is found through AliExpress so they ship worldwide

That'S great!
Anybody has original battery specs that we can compare?

Over in this thread - http://forum.xda-developers.com/showpost.php?p=62442239&postcount=336
Allbatteries looked to have the same thing (and even the same website design, maybe they are related), and was in a more convenient language so I cited that one.

Ain't that battery got a bit too low voltage? The original battery is a 3.9v, but the one he shows is a 3.7v

0.2V isn't a significant difference for a whole battery pack - tolerances can easily lead to the same difference (+ or -).
FYI, the official replacement B01 battery is rated at 3.8V.

That is not how these batteries work all lipo are 3.7v unless they have multiple cells in series then the voltage goes up in increments of 3.7
Also it should be known that a fully charged lipo will read 4.2v and a discharged will read 3-3.3v
The fire hazard with these is likely 2-fold 1 the charge and protection circuit has a flaw that allows the battery beyond a threshold either voltage or temp paired with a bad cell this had a bad habit of catastrophic failures. This is likely why nvidia opted to brick tablets rather than open them and swap the batteries and resell them as refurbished.
Btw that is what I would have done everyone got a k1 style tablet where the package had nothing but the new tablet inside was a return label and the procedure would have been factory reset tablet then package just the tablet no stylus no accessories. As the tablet you would get would be in a similar state... except the stylus slot might have a rubber plug...
Alright.
But has anyone tried a third party battery by now without any issues? For example the aliexpress one? Cause my old shield tablet is still off and awaiting a new battery and a kernel change because the tablet initially awaits the kernel killer to kill off the old one.

Well that depends what you call issues there are several in this thread that reported that the battery did not last as long that is not really what I would call an issue as the original battery was 5200mAh they put a 4250 in or even a 4000 that should last less it is an expected result...
But that said my previous post was a warning against this as the faulty bits might be part of the charging and protection circuit on the battery. Particularly the control chip that runs the sensors and the charging regulator.
Anyone do this yet I bought a LTE model and the battery is seriously eroded.

My post right above yours I did the reading for you the people using the Nexus 7 4250 mAh cell reported that it worked but with an expectedly shorter run time. As loosing about 1000 mAh is a noticeable drop.

Interesting well I found a few batteries that have 5000mah. Not sure if they would work.

In theory you could replace the pack with a bank of 14500 cells. As long as it was a 1s?p arrangement it means 1 series any number in parallel series is voltage and parallel would be capacity and amperage.
The procedure given to replace the battery packs in these tablets involves removing the charging/protection from the original pack and soldering the new pack to the old batteries solder points. So any bare lithium ion pack that is 1s?p configuration should work if it fits. 3.5mm 64 mm 150 mm is the 3 measurements for the OEM pack
