[Q] What is my actual mAH on my new battery

Hi.
I recently bought a new Fat battery for my desire. It promises to deliver 2600 mAH but i have my doubts...
First of all, only the voltage is printed on the battery itself.
Second, I experience worse uptime than on my original 1400 mAH battery.
Third, I guess Iam just sceptical by nature.
So my question: Is there an app out there that will display max capacity?
Or do I really have to measure it with a multimeter?

the only way to measure precisely is using an app called
battery monitor widget
have it measure the current and voltage every 60 seconds
fully charged ur volatge suppose to be at ~4.2V with either battery
the drainage suppose to be the same at screen off
lets say ur phone drains 9mA steady
u should see the voltage sinking slower on the higher capacity battery
i would give it an hour or 2 hours on each battery to check the result
example:
1400mAh battery
steady 9mA current over 2 hours from 4200mV down to 4150mV
2600mAh batter
steady 9mA current over 2 hours from 4200mV down to 4175mV
hope it helped^^

This shows the mAh.

if you brought the £13 one made in China from ebay (like I did) then it's a total fake the stock battery lasts longer, the only good thing about it is because the back cover is that much thicker you can rest it on it's side to watch movies etc...!

That's true. Better to buy the original.

Battery Calibration

I'm using Resurrection Remix (i9505) and i want calibrate my battery (with root). Can anyone say any app and the steps to calibrate ?! Sorry my bad english :cyclops:

Battery calibration is just a myth.
I did it on my old phone and there was absolutely no difference between calibration and no calibration.

I'm asking because i bought a Samsung Portable Charger (2.100mah). The Galaxy S4 have a battery with 2.600mah. 2.100 is 80% of 2.600. But the Portable Charger is charging 95%, so i think it's a software problem.

The battery is polled for its vital statistics by the device. The device translates what it receives from the battery's internal circuits to a percentage, which is reflected in the status bar. All battery calibration apps are useless for two reasons. The first reason is they don't recondition the battery. To do so requires expensive hardware, since this is a lithium ion battery we're talking about. The second reason is that they delete the batterystats.bin file within Android. Deleting that file isn't going to do any harm, but that file is deleted upon the battery being fully charged and disconnected from the charger.
Battery calibration is useless. Any positive results are from the placebo effect.

Then let the battery get to 0 and charge to 100. That's the most reasonable method. Any other app just deletes the batterystats, which also gets deleted whenever you unplug the charger from your phone.

Make battery from 100% to 0%. Don't turn on phone until it gets 100% battery. Then use an app called "Battery Calibration" by Miroslav vitulea.

@gosha98_: Draining the battery to zero will not reset the battery. In fact, draining a lithium ion battery to zero is dangerous, as at zero percent charge the battery becomes unstable and may explode. Back in the era of NiCd and NiMH batteries, draining to zero could in fact "reset" the battery, but not today with lithium ion.
Using a battery calibration app prior to removing the battery off charge will not hurt the phone or the battery since all battery calibration apps do is delete the batterystats.bin file in Android. But, it will not help either.

I bought a Samsung Portable Charger (2.100mah). The Galaxy S4 have a battery with 2.600mah. Doing the calculations you will see that 2.100 is 80% of 2.600, so will charge my phones battery 0% to 80%. But it's charging 0% to 95%. Why ? I don't undestand... Sorry my bad english

Extended Battery with 5600mah not reccognised

Hello,
I've bought an extended Battery for my GT-I9505.
My Problem:
I don't feel anything of the power increase from the new battery... It's still discharging between 8-10 hours like the Stock one.
I deleted the batterystats.bin,
I calibrated the battery,
I charged and discharged it completly several times,
After a quick research I got the Information, that I need another Kernel, becouse the Stock one don't accept the bigger battery (the kernel think the battery is full charged but the battery isn't really.)
And if I combine 1 and 1 my thought is:
The more the battery is charged, the more the output voltage.
The Mobile recognise if the battery is full to avoid an overloading.
This recognise is taken from the output Voltage exact like the percent scale.
When the Stock battery reached his 2600mah capacity the output voltage is for example 4.000 Volt.
2600 mah --> 4.000 Volt --> 100%
BUT HERE IS THE PROBLEM:
As soon as the 4.000 Volt ≙ 2600mah are reached with the new 5600mah battery the mobile thinks its full charged to protect from an overload.
And I think, that the Battery isn't really full even if the mobile says that.
Can anyone help me?

I'm don't think this is the case. I'm pretty sure there are people using extended batteries on stock ROMs.
Could it just be that the capacity is fake?

Not really... The battery has good ratings on ebay

Samsung Galaxy s3 neo extended battery problem

Samsung Galaxy s3 neo. So, my problem is that i recently bought extended 7000mAh zero lemon tri cell battery, and i can't get my phone to recognize it, it thinks it has 2100mAh battery, it's switching off at 1% but after i take battery out and put back in it has plenty of power left. :/ i tried changing Rom, now it's CM 12.1-20150428-UNOFFICIAL-s3ve3g,
Kernel is 3.4.0-cyanogenmod-g5f0621e [email protected]#1
Tue Apr 28 22:17:38 CEST 2015, please help on my stock oryginal rom it didn't worked as well.

Dude.... Extended battery?! These batteries are a big falsh, use ORIGINAL Samsung battery and you'll get more power. I am not joking extended batteries are bogus and drains fast. I switched from extended 2600 mAh (too good to be true) to original new fresh battery. Original one has more power than EXTENDED one...

Dude if u have nothing smart to say just stay quiet, extended battery lasts me for 2 solid days only issue is that i need to take it out and put it back, surely u were just not smart enough to know how to use an extended battery, and to your's extended 2600mAh its weird capacity so guess it was fake, or if it was really extended poropably after ur phone shut down u could just take battery out, put it back in and have like 30% power still... I know its not crap or fake it really is 7000mAh just my system is taking info about battery from hard coded file in kernel.. Gezzz

I don't know. But I don't believe that 7000 mAh battery can be sold for example $40...

Sorry but its no way possibble to use bigger capacity battery with corrected capacity... for example anker 7200mah I have but just with replace trick it use the extended capacity...
The problems is same on charge fase too... 3 time of replaces and reconnect the battery is needed to charge at real 100%.

Edit or Change Battery Capacity?

Hi there,
So I replaced my original battery to a bigger capacity battery (6,000 mAh), and I've been looking for a method to change battery capacity information file for Mi A1 but to no avail. Hence, the capacity is still at 3,080 (even in Kernel Adiutor) and I believe the phone wont charge to 100% 6,000 capacity. There are methods for other phones, but it seems the file is different for Mi A1 (using Havoc OS btw).
Anyone know the file location or any method to change the battery capacity?
Thanks.

what type of battery did you install? I had to change it but I couldn't find one that was so big and I had to replace one that was the same as the original.
sorry for my bad english.

I bought and installed BN31 Rakkipanda with 6,000 mAh, hence the huge difference (almost twice the capacity).

Is that even possible? I mean can u think that they will put twice the size of capacity in same size? I don't think it's 6000mah. U may damage ur device after altering capacity value. Its there for safety

Yea, I don't think that it is really 6,000 in real capacity, it is a third party battery after-all. But my original one was toast anyway, and I had nothing to lose, LOL. After installation, the battery-life in real usage is almost exactly the same as the original one (with the same ROM and kernel), but I have hunch that the battery is still not using its real capacity. I know it is probably not safe, but the phone itself is a backup phone, and I really am curious about the battery capacity.
There were double capacity batteries in Nokia old-times (and they proved to be true capacity -most of them anyway-), therefore I have faith that android phone batteries could be the same.

Hello. You can charge the phone to 100% and then check for the battery voltage. If it is close to 4.2v it means that battery is fully charged.

Tried this, the voltage indicates 4331mV at 100%. Should I keep on charging or disconnect the charger?
By close to 4.2V should it be under (at 50% I peeked the voltage reached only 3.9) or a little bit over?
