How to Check Android Phone Battery Health

Your Android phone battery may drain quickly, this might be due to bad battery health or some apps and games on your Android phone that consuming too much battery. You can check the battery health condition from a hidden test menu of Android. Using this Android test menu you can check different Android hardware information that is not available in normal Android OS interface. From this Test menu you can check detailed technical network information and diagnose problem, usage statistics of built-in and installed Android applications, WiFi information and of course Battery information as well. In this guide you will see how to check Android phone battery condition from hidden Test menu.

Check Battery Health Android Phone

Dial *#*#4636#*#* from Android phone dialer. This will open a hidden Android test menu.

Tap the Battery Information option. Here you will see all details about Android phone battery. You can see the battery charging status, current power source, battery charge level, battery scale and most important health, battery voltage, temperature, type and time since boot.

this didn’t work, after dialing only once and having the std recording: “your call cannot be completed as dialed”, I checked the number dialed in call history, it was what you have here, so there was no reason to redial it. Instead i modified the number you show from *#*#4636#*#*, to the exact same thing but with *#*# at the end.
this time i did much better:
“USSD code running…”
followed by: Can’t be completed.

Please update or correct the info you have here an dontact us, thx

I’ll try this number but in mobile show

Johannes Deml February 22, 2015, 2:33 am

Thanks, that’s exactly what I was searching for!

anudeep February 28, 2015, 2:50 pm

Thank you very much…
Much needed info

howard again March 3, 2015, 10:16 pm

well contacting again for above problem, sequence doesn’t work on the samsung galaxy 3s.
is there a difference sequence for this phone with the current operating system?
And, very sorry for the last line in my original msg – I don’t even know what it meant!

TrickyWays March 9, 2015, 6:29 pm

I have tested this on my Samsung Galaxy S3 and its working fine, would you please tell me exact model number of your phone and also Android version installed on it?

Howard September 10, 2015, 12:32 am

version 4.3
T999UVUEOH1: baseband version or something
3.0.31- 1962493 = kernal version.
JSS15J.T999UVUEOH1 build version
there’s even more but I don’t have a pencil to write it down so I’m doingall these entries by remembering them and typing them in here. (Yahoo? …nope) that’s why you can always catch me saying Androids suck, that means they’re screwy. And if you don’t believe me, try dialing *#*#4636#*#*

Shawt May 4, 2015, 10:12 am

yeah it works u shouldnt have to push anything but the sequence not the call button

howard September 10, 2015, 12:46 am

*#*#4636#*#*ou’re absolutely right, except for one thing: YOU’RE left staring at: *#*#4636#*#*
and so was I. I was sorta hoping to find out some stuff about my battery. but looking at: *#*#4636#*#* was sorta fun too. A little boring, but fun I guess, if you’re into stuff like that.
kind of meditative I suppose

howard November 12, 2015, 11:56 pm

if i don’t hit the call button nothing happens, the sequence remains on the screen, I’ve been looking at it now since before I logged in to reply.

Anyway from the graphic there’s nothing of use except the word °Good”, i don’t know what good the temperature would do and anyone can tell weather it’s being charged or not

Bottom line: never worked, never will, and the info seems usless, unless of course you have a battery that’s “No good”

howard June 22, 2016, 8:33 am

sorry, should say above: “…anyone can tell WHETHER, not weather, their phone is being charged. My only point is that after all the effort to get battery info using this technique and having it yet to work, it seems the information would be of little to no value anyway. I’m really looking for something more detailed than good/no good, like how good and how bad, old, many cycles, percent of original capacity, right?? I mean really.

Wait, just noticed something that could be useful: does anybody know what battery scale and battery level refer to?

Sandra February 26, 2017, 7:53 am

Hee hee ?? weirdo ?

Michael November 29, 2017, 6:54 pm

Yes, well said. And if you want some extra excitement add a couple of symbols. Or if you are feeling a bit down take a couple away. Either way, you cannot lose.

All that does is give current battery status. Doesn’t show overall health.

Howard November 13, 2015, 12:23 am


THANKS I don’t know all what is means, but at least it the screen changed to something.

One thing of interest on the new technical screen is the:
” Level Block: 3 Blocks (0-7) ”
that one seems of interest, or does it just relate to the level of charge?

selvan May 31, 2015, 1:02 pm

I tried in my Lenovo s8 tab. It works but the battery health unknown. Is that means some issue with the battery? Please advice..

jeremy June 10, 2015, 10:28 pm

tried in samsung S5 and it doesn’t work. any advice?

howard November 20, 2015, 8:57 pm

My experience is: it’s not gonna work it’s never gonna work, apparently it does work for some people, BUT ONLY FOR SOME PEOPLE, but it doesn’ work for you and, like for me, it never will. But, the good news is, it really doesn’t tell one gosh darn thing of any use, except tha the battery is “Good”. But how good, that’s apparently left unsolved.
Just as Erica is asking below, it’d be nice to know how good, on a scale.

Furthermore, if it did work, AND we got a “good” then what the heck is using up the battery: I spend a good lot of time checking the running apps, all of which are using 0.00% percent of the CPU btw, with an occasional but rare 0.16%. I turn them all of anyway, this seems to do nothing to extend the battery life. I think WiFi uses a lot of battery though because it ALWAYS scanning; check it out: even when you’re connected to the strongest signal there is, and even if the rest are out of range, it still keep showing “scanning” every few seconds – yeah! And I’ve heard it’s a big battery drainer in lots of other sources, so constantly turn it off when not in use.

Also: none of my iPhone user acquaintances have any of these issues, nor do they spend their day turning apps off, that’s why I’ve bought everyone in my family and iPhone; except me, $479 fior this baby, i still want to get some mileage out of it. Besides, I like swipe…

Ahmed March 1, 2017, 4:35 pm

Are you running a custom rom on your Android phone, this might be the reason you are unable to run this code. I have testing the code and working fine on my S3 and S5 phones.

zimar August 3, 2015, 4:40 pm

It doesn’t work for galaxy s6 edge.

howard September 10, 2015, 12:39 am


… See that?

Sandra February 26, 2017, 7:56 am

? you sound cute in your comments. Such a weirdo. Like are u a serious person or humorous? ?

Howard November 20, 2015, 9:02 pm

p.s., doing this seemed to zap my battery from 97% to 52%! Why’s that?

And what use is the temperature? Mine seems to change all day long

The percent is a joke, that ALREADY shows on the top line of my phone 24/7

Erica August 27, 2015, 8:34 pm

My battery health states the health is “good.” Is that the maximum it can be? Or is there a step above which would be “great?” Just wanting to know if that’s the best my battery health can be at. Thanks.

Ahmed March 1, 2017, 4:29 pm

Battery Scale value shows how good is your battery.
If battery scale is 100 that means its 100% ok and each section of the battery that hold charge is working fine and capable to hold charge.

kiran September 7, 2015, 6:21 pm

satya October 29, 2015, 11:20 am

honer 4x battery will not coming by using*#4636*#*#

Howard, again November 20, 2015, 11:10 pm

Is there anyone who’s following this thread that know of an alternate procedure. One that actually gives useful information

the one mentioned here:
1. apparently only works on some phones but not all
2. Doesn’t give much useful info, It gives, according to the picture here:
-the fact that it’s not chrging;
-the fact that it’s unplugged;
really: that something we’d need to be told?
-the levels at 44, well, every android device shows battery % level at the top of every screen, even before you unlock it
-the temperature, which on mine varies throughout the day, and how is that important?
-and that it’s a Li Ion battery, which is printed right on the battery and which tech support constantly tells you to handle because apparently you need to repeatedly remove it, (unless of course you have an Phone). Besides, every single phone in the world uses Li-Ion, and why would it matter.
– Oh, oh, oh: it also tells that the battery in the battery in the example “Good”; and that’s on a scale from what to what again?

See Erica’s well form question on this same issue.

Bottom line: is there anyway to #1get useful info on your battery
and #2, find out what the heck’s draining it

Ahmed November 24, 2015, 6:49 pm

Information that isn’t useful for you doesn’t mean nobody wants that. There must be a reason company added this code to see the battery information.

Howard November 25, 2015, 8:59 pm

How’s it useful to you? Maybe there’s something I missed

Oto March 30, 2016, 11:05 pm

Possible valueas are:

Max October 2, 2016, 5:45 pm

I couldnt agree more with Howard. All this info is just a bunch of crap and doesnt tell you if its time for a battery replacement. e. g, cycle count and current battery capacity compared to design capacity…

Josh November 21, 2015, 5:29 am

When I type that in, the numbers disappear and nothing happens. Motorola Droid Turbo 1st edition. Does it have to be plugged in?

Dima January 28, 2016, 7:29 pm

Works well on my OnePlus One

*#*#4636#*#* perfectly works with Asus Zenfone 5 February 3, 2018, 9:09 pm

*#*#4636#*#* perfectly works with Asus Zenfone 5

Martin July 19, 2018, 12:28 pm

I have the same issue. Only Wifi info, Phone info, Usage statistics. No battery info. Looked inside Phone info – a bunch of different tools but no battery info.
Maybe they have removed it since Android 6?

Pankaj November 28, 2018, 1:04 pm

This code doesn’t work out for Motorola Moto M how to check in my device
