app to determine exact battery capacity - Samsung Galaxy Nexus

is there a tool to test exact battery capacity in mAh ? I bought a battery on ebay it says 2450 mah. I want to know exactly capacity in it.

Go to your dialer and enter the following code: *#*#4636#*#*. Then select Battery Info/Statistics. It's the 'hidden' menu, but that will display your battery power in mAh.

it does not show mah. battery voltage is in mV .

Ain't this what you're looking for?

I tried once, it running forever, no result. I stopped it. I will try again.

But there must be like tons of apps like this. I mean, I found 2 with just searching for mah checker on Google. So there are apps yes

I tried Nova battery tester again. I waited a whole day it still running, I had to stop it. The mAh number on bottom constantly change. it cannot detect battery capacity.
do you know any other app ?

new battery

Hi,
I got a new aftermarket battery, same size but more power: is there anything I should do (delete battery stats, manually or through an app, etc...) to have it work properly?
thanks

Nothing special to do.
Problem is, if the battery is the same size, its probably the same (or even less) mAh capacity as stock, and just being sold as larger w/ a different label

in theory battery is without NFC so the advertised 1900mAh should be real
is tehre a way to check the real mAh of a battery?
Battery Monitor Widget shows you the mAh of your battery,
By the way, Did you tray to dial the code *#*#4636#*#* on the phone, and then go to the option "battery info"?

As with any battery I suggest charge and discharge FULLY two or three times to condition the battery. Don't top it off for the first bit. If its not genuine, I wouldn't hold my breath. Don't let it sit discharged in your phone lest it leak. My 2cents.
if its the same size as the oem its not 1900mah.

[Q] Verizon Nexus Extended Battery - Help

I have recently purchased the Verizon Samsung Extended Battery for both my phone and my wife's. It is supposed to have a capacity of 2100Mah.
However, using the app, Battery Monitor Widget, the app is reading the capacity of both batteries at 1750Mah on both my phone and my wife's phone.
Is this a fault of the app? Can it be possible that both batteries are bad?
If this is all the capacity I am going to get, I might as well go back to stock and get my money back. I just don't want to wait too long and be outside of the return policy from the Verizon store.
Thanks
Reset the battery stats.

No.
Battery stats have NO effect on the percentage or MaH being read.
That being said, I haven't personally tested my extended via that app...or others.
But I generally get JUST A BIT more juice out of the extended.
I'd say it's worth it...especially if you're (obviously) wanting that extra juice...you can just swap mid-day if need be.

Yes, but it's still a good app.
perhaps you can use the program to compare both batteries directly.

I will install the stock battery tonight when I get home, measure it, and report back.

So the stock battery showed up as 1750 as well. I then did some research using the app's help section. I found out you can do a calibration during charge that will determine the actual mah of the battery.
So I ran my battery down to 17%, then turned on the calibration and plugged my phone in. This morning when I looked at the app, it showed by extended battery actual mah as 2022 after the calibration test.
I read a little more, if I run it down to 1 or 2%, it will give a more accurate mah. Therefore, my test for tonight is to drain my battery then run the calibration overnight again.
I will report back my test results tomorrow.

High capacity battery of 3600mah

Redmi 1s high capacity battery of 3600
i am only sharing link. i am nit responsible if anything goes wrong
konpson brand maximum charging voltage 4.35v
http://www.aliexpress.com/item/100-...Ah-Batterie-Batterij-Bateria/32360795916.html
HSA brand maximum charging voltage 4.2v
http://m.aliexpress.com/item/32365009087.html?tracelog=storedetail2mobilesitedetail
for calculating battery capacity
Look for Wh and V printed on the battery.
mAh = Wh × 1000 / V
Example:Samsung Galaxy S3: 3.8 V 7.98 Wh7.98Wh × 1000 / 3.8V = 2100mAh
Looks too good to be true.However,it might be real,considering that the charging time is 5 hours.I believe this is a protection measure to not overheat the battery,after all it's not an original one.However,I don't understand how are they going to limit the current which enters the battery as that's dictated by the micro controller in the phone.In my opinion,after couple of months of usage,it will broke.
However,if you decide to buy it try to use it only when you don't need the phone too much,so the phone doesn't heat up a lot.I believe heating it up too much might cause the battery to swell and worst case scenario,it will blow up.

are you asking for capacity then dont know
Got the HSA 3600mah battery today from aliexpress. Have attached some screenshots.
Inserted the battery into phone. It fit perfectly and charging it now.
Please suggest some android app that displays the correct battery information. So that we can validate what i received from HSA.
Will also update the charging hours it took and how long one full charge lasted for me with HSA battery in the coming days.

How much did you pay it finally ?
As i checked in the Aliexpress they are charging too much for delivery , so did you choose any particular vendor ?
And finally keep posted abt the performance of the battery
it was free shipping only... as previously mentioned paid only 595.
I am not able to find any app that displays the correct mah of the battery.
Its getting charged in 5hrs using redmi charger...
Got an usage time of more than 24hrs.. which i was already getting in my stock xiaomi battery... with dual sim, data and Wi-Fi usage.
So i guess the battery is similar to the stock one given by Xiaomi.
Should try konpson next as suggested by deepak kumar android.
Try better battery state app

You can use "AIDA" to see battery information, also "Ampere" is good enough to show battery information like ~Input Current, Output Current etc.
Used AIDA app as suggested.
Attached Screenshot of data showed by AIDA app with HSA battery.
Thanks for the support

Haha
If it's exactly same size and type how on Earth it can have more capacity? Use simple logic guys. It's scam.

Wrong battery capacity

I am currently on RR rom.
I installed ampere to check the charging speed but was surprised to see the battery capacity showing 3,350 mAh instead of 4000 mAh.
Any solutions/ideas?

It might be an app issue. You can cross-check the capacity through cpu-z app.

Cpu-z doesn't show battery capacity
I think it could be a rom/kernel issue. I find the same behavior in multiple battery / hardware info apps

Yes I also think so.

NexPlay and extended battery help

Hi.
My name is Andre.
I have an xperia play that I've been using as a pocket emulator for years.
I have the NexPlay Rom installed, as well the recommended LuPuS CM9 Kernel and .58 Enhanced firmware.
Recently I bought one of these 4500 mAh battery and back cover from ebay.
The original charge it came with lasted a good while so I really believe this is not a fake battery.
But I can't get the phone to recognize the new battery capacity and charge it. The phone seems to only charge it up to the original 1500 mAh.
I've added the following line to build.prop (the line wasn't present) through the BuildProp Editor app:
ro.semc.batt.capacity=4500
But even after clearing the cache, davik cache and resetting the battery stats, I see no changes.
Can anyone help? I'd really appreciate it.
sorry i cant help, but a 4500mah battery sound nice, when i had the xplay i had a 2450 mah and worked fine, the only problem is it decayed its capacity very very quickly

Thanks anyway.
Since my original post I've done more reading, searching and testing.
Turns out there is nothing functionally wrong with the phone, other than it still thinking the battery is 1500 mah for battery duration calculations.
The charge percentage is correct, and the phone is charging the battery until it reaches a voltage of 4.2, which means it's full.
It's the battery itself that is only taking in about 2800 mah. The seller said he would send me another one.
