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,

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.

LOL...you are actually having a better luck than I
I think I actually damaged my battery by left it in the car for too long =(

[READ] How to read and understand battery statistics

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

Battery Stats inaccurate

I've spent hours researching this issue online, but haven't found a clear and accurate response. Here's the deal: I have a Nexus 6p with Marshmallow and a 3450mah battery.
I cannot for the life of me understand the stats in the Android battery settings, particularly when compared to gsam. I've attached photos of my gsam, Android battery settings usage, and screen time usage. These were all taken simultaneously for comparison purposes.
As you can see, per gsam, I had the screen on for 4hrs and 5 mins, which as you'd expect, would eat a ton of battery. In fact, it took up 79% of the 70% of battery that I'd used up to that point (note: phone still had 30% charge remaining). Doing the math, .79 * 70, means that, draining from 100 with 30 left, 55 came from the screen. Sounds right.
Okay, cut to the Android Battery stats. First off, it says the screen represents 12% of the battery drain. And sure enough, when I click on the "screen" descriptor, it shows that the screen has used 424 mah. The battery is 3450 mah. 424/3450=~12%
This makes no sense. I had the screen on for 4 hours and it only accounted for 12% drain? What's more confusing is that all the listed items on the battery screen don't come close to adding up to 100%. I understand this changed at some point in Lollipop, I believe. But again, I have no idea what these numbers reflect now. What in the world is 12% supposed to represent?
I'm asking because, first, I want to understand, but second, I returned a s7e because of the well documented high android system drain listed under Android Battery Settings. I'm starting to question whether that's even a real issue since these stats seem meaningless compared to reality. There is zero chance that my screen only used 12% of the battery. Just using simple logic, GSams output seems more appropriate.
So I know what you're going to say... Use gsam. Yes, but, I want to understand what the native battery settings actually mean. If it's completely misreporting usage, it means people are making decisions on phones and changes to enhance battery life based on completely worthless information.
Please help! Not knowing is eating at me.

That percentage is the power use. You answered your own question.

Yes, but if it's the power use, how does it make sense? The screen only used 12% of the entire battery, even though it was on for four hours straight with, as you can see, not much else hitting the battery. How did the battery drain down 70% if the screen only used 12%?
And why does gsam show that the screen used 79%, which seems far more accurate given that the screen was on for hours.
Would love clarity.

I don't think you're going to get it mate as it's a completely useless section of settings, it should be broken down to the nitty gritty details.. I think using gsam is the right choice the battery section is pants.

I believe the percentage showed in settings is based upon hourly use. Whereas gsam is giving you the total usage.

I'm far more inclined to believe the native battery stats. The actual screen doesn't use that much power as everyone tends to believe. What uses much more power is the CPU, and the CPU is generally only active when the screen is on and you are using the device. Checking my own stats, I see that my screen-on battery usage per minute is slightly higher than yours, but I like to keep my adaptive % set to around 60 during the day.
So, the screen % in the stock settings is probably accurate for the screen only, whereas GSAM seems to be measuring total battery used by all components of your device including the CPU, while your screen is on. I'm also not convinced that GSAM has access to mAh usage of the actual screen. It could be if you had installed the GSAM root helper which must write a file in the system partition.

Interesting theory, but the issue is that on other devices, like the s7e, the stats output from the stock battery settings look completely different. Meaning, the list of items power usage adds up to the amount of drain. I still can't figure out why the 6ps report numbers that make no sense. Even if the screen isn't as much of a hog as the cpu, the numbers in the battery stats should have some value to them. Also, cpu would be part of Android System, which is listed even lower on the stats.

Ummmm it makes pretty good sense. If you're using 12% of the battery per hour. Then with 4 hours screen on time you end up using roughly 50% of the battery. That seems pretty accurate to me. Pair that with all the other things that are eating up your battery and it probably adds up to the 70% you used.

Well it's measured in milli amps per hour. Which is the power used on an hourly basis. So I would assume the percentage used is on an hourly basis as well. And if you do the math multiplying the percentages used based on the amount of time each app is running it equals out to total percentage used.
I broke it down in percentage multiplied by hrs of use. At 24% battery left here were my numbers.
App: Percent used × hrs used = total usage
Screen: 10% × 3.25hrs = 32.5%
Car drift racing: 5% × 1.23 hrs = 6.25%
Android OS: 5% × .98hrs = 4.9%
GP services: 4% × .2hrs = .8%
Android system: 4% × 1.26hrs = 5.04%
Cell standby: 3% × .4hrs = 1.2%
Phone idle: 2% × 11.98hrs = 23.96%
Tapatalk: 2% × .116hrs = .23%
YouTube: 2% × .16hrs = .33%
Google app: 2% × .116hrs = .23%
GP music: 2% × .116hrs = .23%
Chrome: 1% × .08hrs = .08%
Total = 75.75%. Round that to 76% and you're left with 24%.

If you're correct, that's an absurdly obscure way to present data to the consumer when other phones make it simple by showing an absolute number. Why does the s7e show an absolute number, but the 6p does not? Aren't they both on Marshmallow?

Yes but the 6p is pure Google. The s7e has touch wiz interface which is very different from stock Google. They both have different battery apps.

If TouchWiz takes the information in the AOSP Marshmallow to present the numbers in a different manner, isn't there a way to do that on the 6p, in theory?

Of course there is. Don't use the stock battery app lol. Gsam with root companion works great IMO.
I'm sure there's some way to edit the way the battery percentage is presented. Change it from hourly to total usage. But I have no idea how to do that.

No it doesn't, any battery app that's actually accurate requires root.

Would there be a way to implement the s7e battery stat app into our 6p? Rooted obviously. I've never been a fan of the method used by Google.

Battery life
My phone's battery is draining mostly because of Android OS. 15 percent when my screen uses only 8% mobile radio active for 2 n half hours. what is the problem?

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 ****."

Uh I know it's not 100 percent accurate but thought it was odd that it should that little. Thanks for your wonderful insight.

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.

battery drain in hour

hi since using my OP wireless charger on 2 occasions i will take my phone off charge but not do not use it ,i pick it up an hour or 2 later and i get a warning battery ,,battery to low ,and have to recharge really annoying any thoughts ?

I have a high screen off/flight mode battery drain. About 10% in 5-6 hours. No idea where this comes from.

Around 8 hours Display Off = 2-3%

Yes I get good sot. But what I experienced on 2 occasions something went dreadfully wrong ,total battery drain in an hour or 2 by not using phone after fully overnight charge.
