Hi,
in past it was possible to check real current battery capacity in mAh. I mean in service menu when you type:
*#*#7378423#*#*
Now there is no info on battery capacity.
Any idea how to check it?
Maybe different code?
I have my doubts Android reports it even close to accurately. Maybe Sony does it better but run time is generally the best indicator of actual capacity. Accubattery Pro's mAh gauge gives a good -relative- vs actual measurement. Again Accubattery's discharge history ie run time is the best method I've found.

Im using stock ke7 that is rooted. When im using currentwidget to show the battery drain it says no data. Battery % and voltage is shown correctly but not the actual drain.
Is it only me or is this problem for all sgs2?
current widget doesnt support Samsung devices because the way the hardware reads the temperature or something is not accessible...not sure the exact reason tho but there is another app called "battery monitor widget" which displays some "ma" but it will just be an estimate so it won't be 100% accurate..
the max10742 fuel gauge chip in the galaxy s2 does not output current readings, only voltage, temperature, and a few others. the original galaxy s used the max10741 and it also did not output current readings.
most other phones, like HTCs use the ds2784 in the nexus one for example, and they DO output current readings.
i think there is a way to re-write the battery driver to maybe change this, but thats a project for another time.
battery monitor pro only guesstimates mA readings when it cannot find actual current files from the kernel.
Guys, Recently i bought a new sgs2 battery from ebay having capacity of 2000mah. But i m not sure it is of that capacity
can u tell me how can i confirm that???
I have tried battery monitor widget but it is showing 1650mah
You can't confirm it with the phone. You need specialised equipment to test batteries. Best you can do is run the phone under similar conditions for the same amount of time with each battery & do a guesstimate.
I bought a 2000mAh a few mths back and after using it for that long, it's probably pretty close to its rated capacity given I seem to get around 20% more usage out of a charge compared to the stock battery.
Due to hardware limitations, battery apps can only provide an approximation of how much battery you have left at any given time & how quickly it's draining.
Plenty of posts on here over the last few months explaining same better than I can if you feel like having a search/reading
Did much of search on google but couldn't find a better solution
tx for ur reply dude
Hello,
I have spent many hours of reading trough internet, including xda-developers forums and lots more. Maybe I'm not lucky and just didn't find the one right page/post where is what I need.
I have very simple problem, I suppose many people at some point gets to that question - is my phones battery in good shape and if I buy replacement is it at least close to promised capacity.
So only way to get that info is measure or approximate real battery capacity.
As there in system are available all required parameters for calculation - current, percentage/voltage and of course clock. It shouldn't be hard to calculate estimated capacity.
Of course it'll have to gather some data to calculate data, but it is quite simple, and can get more accurate as more data is acquired and saved.
I have found few projects who claims to do so, but unfortunately without luck.
Battery Monitor Widget - shows all data needed, but as capacity shows some kind of calculation between charge level and manufacturer/entered capacity, so it shows charge level in mAh, but there is nothing like estimated battery capacity.

Found post with Current Widget usage, but unfortunately it doesn't work for my Galaxy S5.
Post: http://forum.xda-developers.com/showthread.php?t=1019786
As conclusion, I suppose it shouldn't be very difficult to make such app, unfortunately I'm not developer and even familiar with mobile platforms development. Maybe there are someone who is interested in same stuff and can develop
Any comments are welcome
Cheers!
So take apps like Ampere for example, they show some battery-related stats, one of which is battery health. I've yet to see any other value than "Healthy". So wondering how does the app / system determine the battery to be in good shape or not? Does it calculate the current maximum charge the battery can hold and compare to maximum, something like 2970mAh / 3000mAh can be considered healthy? Does it use the voltage value? Does it just use the temperature?
To provide context, my Note 5 is feeling like the battery has gone bad, I'm getting very limited screen on time even with light usage. Ampere and similar apps still show my battery as "Healthy", so I don't know if it's just a bogus stat or something scientific and can be trusted (which means my problem lies in something software-related).
Thanks for any input!
AccuBattery detects the X1M3 battery as 4380 mAh which contradicts official literature. However, that's not to say it's incorrect. Is it truly 4500 mAh? Not been able to find a teardown yet, unsurprisingly.
Consider Accubattery's measurement an estimate. I find it's history of SOT useful for spotting excessive battery usage as I know what it should be using per hour SOT as well as at rest
3C battery monitor reports the same. (Sony XQ-BC52)

What is the difference between typical capacity and rated capacity in batteries?
Answer (1 of 4): Rated capacity is what the battery can store and deliver according to the manufacturer. Using any form of lead-acid battery and utilising its full rated capacity by daily cycling it 100%,will result in a speedy destruction thereof. In practice, it is recommended that lead-acid ba...

This answers nothing. 3C battery monitor reads the data from the battery profile set by the manufacturer. So sony states that the xperia 1 III has an 4500mAh battery, but the profile reports 4380mAh. Thats quite a difference.

Many manufacture do this, they round the figure, so sony is still correct.
