[READ] How to read and understand battery statistics - Galaxy S II General

Lot of people (me included) are confused about how to read and understand battery statistics. I think it's possible to find misunderstanding in many of the battery usage threads I have been reading, making discussions muddy.
As an common example people often think that a high OS-System battery % equal high OS-System battery usage/drain ... but I don't think this is true!
Let me show two examples:
Example 1:
On battery 26 hours using 43% battery or roughly 1.65% battery per hour.
Screen 23%
Android-System 22%
Android-OS 21%
Voice call 10%
Standby 9%
Newsreader 7%
Phone not active 6%
Google services 2%
All together 100%.
Example 2:
On battery 10 hours using 50% battery or roughly 5% battery per hour.
Screen 55%
Android-System 8%
Android-OS 9%
Voice call 7%
Standby 5%
Newsreader 7%
Phone not active 7%
Google services 2%
All together 100%.
One should think that Android-System and Android-OS drains more in example 1 than it does in example 2 ... but I think it's the opposit!
Example 1 Android-OS have been using 21% of those 1.65% --> 0.33% per hour.
Example 2 Android-OS have been using 9% of those 5% --> 0.45% per hour.
Would someone PLS verify that I understood it correctly, or feel free to correct me if I'm wrong

You are 100% correct!

Disclaimer: This is what sounds logic to me and what I think is how it works. Now I have no specific knowledge about battery so this might be completely wrong.
First read this, or don't but it makes it easier to understand.
Now going on in that trend lets say you have a gas tank of 100l liters (same as 100% battery). In your first example 43% got lost, so 43 liters. 21% of the 43 liters got drained by the hole. Thus 43*,21=9,03 liters.
Second example: 50 liters total drained, 9% by the hole. Thus 50*,09=4,5 liters.
So the first example drained more.

Yes you might be right ... but what about the time factor?
Agree that in example 1 OS uses more juice than in example 2, but over a much longer time. Meaning less average drain!

Factor in the "leak"(drainage) over time and you can see the OP's point.
Scenario 1 : 9.03/26h = 0.35/h
Scenario 2 : 4.5/10h = 0.45/h
The actual RATE of loss/drainage is more important.
This might give someone with lots of spare time to tabulate a league table of battery dissipation/drainage for different ROMs/firmwares. Or more interestingly across different devices using stock ROMs (eg SGS2 vs Sensation vs Atrix vs LG2X, etc)

I agree, but the first example drained more but slower and the second less but faster.

..and hence the battery in the first scenario will last longer than the second, assuming both start at the same capacity.
We are now on the same page

no matter what, there is a bug! compared to other 2.3.3 phones, my nexus one has been unplugged 7.5 hours right now, with 1 hour of screen-on time. and my android OS is reading 2%, 2 minutes usage. that is TWO MINUTES. that is the way its supposed to read. i've gone 24 hours with 12 minutes usage for android OS.
somethign is just not right with the SGS2 reading...

I need to revise maths once again
but this discussion somewhat helps to clear the confusion

Is My Battery Damaged??

I've got an issue and I'd like to know if anyone else is getting this. I've read the forum threads but I don't know what's considered "normal".
Well, simply put my battery power is pretty poor. With no GPS or push internet, my backlight on Auto, and “moderate” usage (8 hours standby, 90 mins on the phone and 3 hours “other” ranging from Internet to games to taking notes), my battery is almost wiped out! I can't get through the day!
This is a far cry from the specs on the HTC website (which claims up to 340 minutes’ talk time), and from reviews I’ve seen saying their phone lasted a few days without charging. Is this normal or do I need to get a battery replacement? My previous phone - an HTC Trinity - seems to have much longer-lasting power (beyond the simple difference in mAh).
I know, some people might consider the usage above to be "heavy" but as phones evolve to take on more and more functions, of course you're going to end up using those functions. I do have TF3D on (I know that appears to guzzle more power).
I am considering the 2200mAh battery but would prefer not to get it because of the thicker profile.
Comments or advice appreciated!
Thanks,
Wassim
Sounds pretty 'normal' to me.
Make sure you keep your phone on charge whenever possible as this will maximise the useable capacity when not being charged.
but as phones evolve to take on more and more functions, of course you're going to end up using those functions.

You've summed it up - we use our phone with it's lovely screen much more than before.
3 hours “other” ranging from Internet to games to taking notes

This is where the battery goes, Internet and Games!
When you leave your phone overnight with nothing running, no push internet etc, the battery should only go down, say, 3-4% at a guess, which would indicate the battery's OK. If extrapolated, this indicates a few days standby only usage.
That's fair enough Pete. I'll test that out.
HTC website says the phone should last up to 360 hours on standby. Therefore 8 hours should use up 2.2% of the battery, say 3-3.5% to account for inaccuracy in the battery readings.
Unfortunately my battery only reads in increments of 10%, how do I display the remaining power to the nearest 1%?
Thanks,
Wassim
There's loads of free alternative battery metering schemes, my own fave is "Batti", which puts a coloured bar full width across the top of the screen which shrinks as the charge goes down. If you touch the bar with stylus, you get a page with charge shown 0-100% in 1% increments. Batti's very configurable too.

Unfortunately the duration life of your battery is normal for the stock one.
I have these performance for the battery:
- half day for an intensive use
- one day for a normal use
- one day and half for a low use.

Battery Probem need suggestion...

Hi Every One I dont know from were i will start Ok
I have a Problem of battery its drain soo much even i dont use the mobile Much and its drain so much.
BaseBand is XXJPY
Rom is Unlimited Rom
Please help me what should i do
1. you should use the search function, there are quite good threads concerning battery life
2. you could post in the general or, even better, the Q&A section.
3. you should post your stats, just saying the battery does not last long enough is a bit vague, if you're used to a old nokia anything under 10 days will seem short
4. when did you flash the last time? the battery meter needs some time to be accurate again. to speed up the process let the battery drain under 10% and then charge fully. after 2-3 days you should get accurate results.
5. you can check the battery statistics in the settings an see what drains much energy (besides the display^^), if it's any single app you might wanna look for an alternative. You can also think about apps you have installed that need the internet for updates/communication. such as skype and facebook. Especially skype has not the best reputation.
6. what kernel are you on and has it tweaks (speedmod f.e. access able in recovery) you could enable?
7. Check what modem version you have ("baseband" in the settings -> about phone) and whether it's compatible with your region. a thread with information on that is linked in my signature.
8. To tweak even more you can try apps such as Tasker or juicedefender
Hmmm OK^^
First of all i used Darky rom wth frimware XWJS5 and Kernel (stock+Voodoo-Froyo-GT-I9000-XWJS5)
And now i install Same Firmware its (FROYO.XWJS5 Build Number) And i install Unlimited Rom 8.0
I see in Battery use the (Display take 60%)-(Cell standby take 18% Wifi take 15%)
Baseband version is I9000XXJPY
I install that Rom yesterday and i put in Charge When the battery in 4%
And Still i didnt install any Software like facebook or skype
If we say that we want like nokia Then its just sound like Nice joke But dosent work at all.
Here is only problem that i wont take much longer even i dont use jst power Off
well and how much time has passed since you charged and on what % are you now?
I guess the battery life will get better in a few days by it self as mentioned above
I Charge the mobile in evening at 3 when the mobile clos it self
So now the battery life is 85%

So you charge every day at 3PM at which point you have 85% left? Or you lose 85% over 20h? The later would be a bit much
Unless you watch lots of videos/play a lot on your phone. to make it easier:
a consumption of under 2% per hour on standby (screen off, just laying around) is normal. For reference values look here
now its 82% wthout doing anything

No offense taken.
Its just for a quite a long time now it was known to just about everyone that smartphones are very battery hungry and it is good to get a full day from one charge.
And yet we see still such post about battery. Kind of pisses me off.
Well in the case of osasih we have 85% at 05:25 and 82% at 05:59 which makes 3% in 34 minutes. That equals to 5.3% per hour, so that the phone should last almost 20 hours - that's fine.
However, in my case I see a drain of almost 9% per hour which is far too much IMHO. I logged yesterday when I left work charging until 65%. Whith 9% per hour it should have lasted until midnight, but suddenly it dropped from 33% to 2% in only one hour!

Yes right saying But some how it drain so much like if i listen songs yesterday i was listning songs and i fall sleep the battery was full and wen i wakeup the battery all most finish..and even wen i clos the mobile put the batter out and reopen it again so i see batter is 10% befor closing the mobile it was 53%

I'm going to assume that you read my post on the first site^^
try rebooting the phone and look whether the problem persists. I know it sounds stupid but I think there's a bug somewhere that eats battery after flashing or randomly after boots. I only experienced signs of it after flashing since I don't really shut down my phone on any other occasions

OK i will try to flash again and see how it takes but rather flashing will break the mobile isn't? lets try wth darky final rom 9.4

[HOW TO] Read your battery stats correctly!

Everyday i have a ton of people asking me and complaining about battery life.
So i figure i give you guys a small insight on how to properly read your battery stats.
when you are in the battery stas section of your phone.
settings > battery & data manager > battery usage = battery percentage
the screen looks something like this
4h 35m 10s
phone idle 36%
screen 25%
etc etc
when you are looking at this screen, the percentages do not resemble the amount of battery consume. but the amount of time that particular service/status its ran on battery
so no. your phone idle has not consume 68% of your battery
your phone is being idle 68% of the time its been on battery.
so no. your screen did not consume 25% of your battery
your screen is been on 25% of the time your phone is been on battery.
i hope this helps to clear up so of you guyses doubts and concerms about battery life.
so what app would we use to determine how much % of the battery is being used by certain things, like the screen?
I dont understand why its been so hard for people to understand this. Everyone that has been complaining about phone idle using battery has caused my brain to hurt.
Thanks for putting this out there SamCripp, I don't think many people understand this.
Are you sure sam. Numbers don't add up on my phone to support that.
I thought the percentages of each service is what percentage they have used of the total used battery.
Example:
Battery at 80% (20% used)
So if phone idle says 30% I thought that meant it has used 30% of that 20% or approximately 7% of the total battery.
I say this because for example my wifi shows being on the whole time I have been unplugged but its percentage is only 6%.

I started writing a rebuttal to this, with math and everything, but when I was doing the math, I realized that my battery is in fact working fine. If the phone was idle for four hours, the battery should be around 96 percent, and phone idle will have taken around 100% of the battery usage. Thank you for making me do the work and figure it out. Now, to make sure that this is indeed the case with my battery once I fully charge it and calibrate it.

I'm going to have to question this theory.
I charged my phone yesterday afternoon and left it off the charger overnight so it's been 16 hours since charged. Well, when I check my stats it says "Phone Idle" is 49% and "Display" is 31% but when I click on them the "Phone Idle" says it's been on for 14 hours and the "Display" has been on 2 hours.
So, according to your explanation the "Phone Idle", in theory, should read around 88% and my "Display" should be around 12%.
So to me, the stats are telling you how much of your battery has been consumed by those particular processes/components. Not how much time those processes/components have been on.

I believe Sam is right.
My phone idle is at 54%, with 91% battery left. When I tap on phone idle, it says 2h 35m (when I woke up). For display, at 32%, it says 15m. Android OS is at 2%, and cell standby at 10%.
So I don't see how my phone idle is taking up 54% of my battery.

Lets see:
Sams way - IF phone was idle for 54% of the time since change that would mean the phone has been unplugged for (rough math just woke up) about 5hrs
Therefore for display if it was 32% it should have been on for 32% of 5hrs or about 96min. For 15min it would only be about 5%.
My theory: Display used up 32% of the total 9% of battery that has been used so far or about 3% of the total battery.
i welcome questions and critisims, this is a comunity, is a group effort. the only thing i wont accept is flame and trolling!
and you are right sir im not offended!

leds, notifications and all general visual and vound and vibration would account for display. == theory as i dont have the source to confirm.
on programing INPUT is extremly generic. anything from mouse to monitor is in this category. so it only makes sense display would be the engineers way of categorizing!

It's not so hard to understand. The phone already drained 9% of your battery and in that there is 54% of drainage caused by idle, 32% caused by display and so on. You can't say that 2h 35m caused 54% and 15m caused 32%. It's obvious percentage and time aren't connected. I think some ****ty moto-app is running whet phone is idle and that cause short battery life. I had few android phones before and idle was never higher than 20-30%
Utilising the scientific method!
3 days ago i drain my battery clear battery stats charged up to 100% and spend the next days with out recharging once. each time i got to 24 hours i rebooted, so my battery stats would clear in the battery stats section.

No there is a correlation between percentage and time its all relative to the total battery used:
1 hr unplugged total battery at 90%
-Display on for 20min might be read something like 50% / 20min (50% of 10% of total battery used this far)
-Idle might be 50% / 40min
but if you then just idled the phone for 8 hours new readings would be
Total Battery 60%
Display 15% / but still 20min ( 15% of 40% of total battery used this far)
Idle 85% / 7h 40min (85% of total battery used this far)
-Display
If you add up the numbers they always come up to around 100% (+/- a few percent for rounding errors) if it was app on time then there would be over 100% as we have "multitasking phones" ie display is on but so is my XDA app and irc running in background.
as you can see from my pic above all those times are solid. i used my phone for about 4 hours yesterday, with the hear and there of opening stuff up we can added up to about 5hrs and a few minutes the rest of the time is sit, as i was at work and compiling cm! i do see your math checks. but run the experiment for yourself.

I must be a little slow this morning because I don't understand your experiment or what it has to do with "Reading" the stats. Your pictures don't show any times which is what we are talking about.
We can both agree that people get confused and thing that if there idle says 50% they think it has used 50% of there total battery which is not true.
So the question is simply - does the individual stat for say Display or phone idle represent either:
a) percentage of time since unplugged that app/service has been used/on for or
b) percentage of "total used battery up to that point"
Not sure how your experiment proves or disproves either of the above. Except that again as I said above the percentages add up to 100% +/- so I am not sure how that could be unless its b.

Battery at 94 percent and says estimated life 5 hrs???

Was just wondering if anybody else had run into this. It says I'm at 94% and its showing I only have 5 hours of battery life estimated left. Can this be right? My Samsung S7 Edge has 87% and it's showing it's going to last 10 hours. I'm running 7.0 nougat also.
Uh, that statistic doesn't mean jack ****.
If I've hardly touched my phone for a few hours, it's going to say 20+ hours remaining (with the current usage), so that is completely irrelevant for almost any case.
it's the estimate based on the current use, so if you unplug the phone from the charger (100%) and use your phone for 20min and the battery go down to 94%, then the estimate will be based on that and will show ~5hour left.
so basicaly , what adsubzero said : "that statistic doesn't mean jack ****."

It's not that it isn't 100% accurate, it shouldn't ever be even considered.
It basically takes into account what have you been doing since the last full charge and tries to project the remaining battery life.
That would only be accurate if you were using the phone in the same linear behavior from 100% to 0%.
The conclusion: don't worry about that.
That's would be 5h SOT if you using it constantly until the battery drain out completely

Check the screenshot.
So this would mean I have 13h SOT left?
Nope, over the 9h I've used 40% of the battery, so it estimated that it would take 13h for the remaining 60%.
See how it draws a straight line to 0 from 100, which means it's a simple linear calculation.
If I went beast mode and started gaming it would be at 0% in 2h or less, and that is a big miscalculation which is why it shouldn't be taken seriously.

What % of your battery is used by cell standby?

Hey guys So even though the battery life on the g5 plus is amazing, I'm not quite getting the battery life other people on here get. So I checked the battery thing and saw that cell standby uses a lot of battery even though I only have 1 sim card installed.
Specifically, cell standby has used 18% of my battery so far and I am at 10% charge right now. It's been 24 hours since my last charge. So I wanted to ask, at 24 hours, how much of your battery is consumed by cell standby?
Or rather, say how many hours it's been since your last full charge and how much % is used by cell standby.
mine is somewhere in that range, but the overall battery percentage is very very low (1% every 2 hours or so on good days).
Keep in mind there are 2 important numbers here.
1) Battery percentage lost (IMPORTANT)
IF your battery loses 10% an hour, this is a big deal. IF you lose 1-2 an hour, you are good!
2) Percentage by service (MUCH LESS IMPORTANT)
This is helpful to diagnose rogue apps or services, but is much less important, unless #1 is very high.
Remember, 25% of a 1% loss over 4 hours (random number here) is still practically nothing.
#2 does not matter at all (generally) if #1 is an acceptable % drop.

Thanks for replying. I asked someone for a screenshot of their phone on this and I saw they have a 4% drain over 19 hours. I have an 18% drain over 24 hours.
4%/19 hours = .21 per hour and a little over 1% per 5 hours.
My phone consumes 18%/24= .75% per hour.
So the difference is very significant here and it clearly is a problem. A extra chunk of battery is never a bad thing.
ok. wanted to double check that real quick.
What about coverage? low coverage puts a pretty heavy drain on battery, and I have seen this reflected in Cell Standby. also, are you using Wifi/is it on all the time?
Cell reception plays a huge roll too and whether you're on wifi or not. And if you're constantly turning your screen on. When the phone detects it's in the pocket or just sitting there it'll go into extreme power saving mode (thanks to nougats "Doze" feature). That person who only got 4% drain over 19 hours most likely had their phone just sitting there and never touched it. At that point I would ask the question, why do you even have a phone?

My wifi is always on. I haven't had a problem with cell coverage ever with any of my previous phones. I'm going to try using this app "Gservicesfix" from the store and see if that fixes my problem otherwise I'll do a factory reset.

My reception is fine.
The person who's screenshot I saw definitely does use his phone a lot. He has like 28% drain from screen.
