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,

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.

[Q] Best way to train a brand new battery

there are alot of mixed opinions on how to properly train a brand new battery, I'm talking right out the box 5 mins ago. Some are saying let the new battery drain and then start the charging/discharging and some are saying charge it right out of the box.
Anybody have a definite answer that has worked for them? Battery life has been an issue for me in the past and i wanna get this one right. thanks guys!

I charge it right out the box then do a full discharge and charge it back up again.
I think I'm a moderate / heavy user and I still get quite good battery life. Averaging around 20 hours before I need to charge.

It's Lithium Ion. You don't need to train it.
Android however needs to figure out how long it can run before the battery is dead. Charge it til it's full and run it down. Do that a few times and the OS should get a pretty good idea on where the battery is sitting.

yeah sorry for not being more clear, this is what I meant. not training the battery itself but the system so the battery stats are more precise

Wasn't there a special HTC-approved charging strategy that supposedly improves battery life dramatically? Was that ever debunked as BS?

you are not a heavy user then. I got about 12 hours with 2G only selected for most of the day. switched to HSPA. hspa+ 8megs killlllz my battery. I went from 70% to about 30 within a few hours just sitting in HSPA+ area and browsing and checking emails and facebooking. at about 12:30 that night i was at about 15%

You need to delete batterystats.bin from system if you get inaccurate readings. And yes, lithium ion batteries need no training. That was the older type nickel-whatever...

So, you're basically saying we need to train the OS, not the battery, am I right?

I always gave the battery a full charge and then let it go down to 0 and finally power down before re-charging. After doing that a few times I just did whatever as far as charging goes.
I also used to charge a lot here and there through out the day. I know only charge when it's low and I know I am doing a full charge. Not sure if it makes a difference with battery health, but I feel like I notice a difference.

Lithium Ion batteries should not have complete discharge cycles. Keep it above 40% when you can. Charge it regularly.
http://www.batteryuniversity.com/parttwo-34.htm

well I did the Evo trick and... i'm at 12 hours off the charge and 34%... that's with web browsing, texting, gtalk, phone calls, etc.
I think the GSM Auto (PRL) has helped a bit as my "time without a signal" went from 44% to 0%.

There are too many different answers from discharge at half, charge to full then discharge, and not let it discharge below 40%.
I think we should all test and log the different techniques.
So far
44 hours with light use
21 hours with normal use
15 hours with heavy use
and what I did was discharge at half and fully charge, also I dont let it shut down by itself and turn it off at 1 %.

You can read all about it here: http://forum.xda-developers.com/showthread.php?t=670999

Okay, I read the post and did the evo trick, from my understand it stops your phone from constantly looking for a network.
while I made the changes, am I suppose to have "use only 2G network" check or unchecked? Also my connection changes from E to H all the time with this trick, is that suppose to happen because from my understanding it should stop it from switching networks?

I just tried the GSM Auto (PRL) evo trick.. now to wait and see if this helps at all..

Whoops, I didn't mean to imply that the evo trick was the GSM Auto (PRL) setting... I was talking about this:
To also help with Battery Life you can do these steps exactly: 1) Turn your device ON and Charge the device for 8 hours or more 2) Unplug the device and Turn the phone OFF and charge for 1 hour 3) Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for another hour Your battery life should almost double, we have tested this on our devices and other agents have seen a major difference as well.

[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

P8 battery draining fast

How long is the battery lasting (in hours)?
Android will take up 100% of the battery usage if you do nothing with your phone (that is, the OS will discharge the battery just keeping the phone working).
I would expect Android to take up more of the battery usage overnight since you aren't doing anything else with it. A "percentage of usage" is just the share that entity is using relative to the other things running on the phone.

Yeah, That makes sense, but how much draining is reasonable over an 8 hour period at night ? 2% per hour is reasonable ?

This means the phone would last two days hours if you left it alone, and Android would be responsible for only half of that drain by your previous observation. Doesn't sound unreasonable.
What's using the other 50% of the battery overnight?

I will review and report back.

Here's the battery usage screen after 7 hours:
https://drive.google.com/file/d/0B0O3XF-vHiCKZDFXYzNEWWtsLW8/view?usp=sharing

That's too much, I'm getting like 3% drain over the night (5% with the wifi but no real synchronization). Do you really need NFC and Bluetooth during the night?
PS. Try to restart your phone

I turned off NFC and battery draining slowed down significantly.

Horrendous battery life - Can someone help? (15% in 10 hours, 30 MINUTES SoT)

Can someone please help me with my battery life? My phone drained 15% in 10 hours with barely 30 minutes of actual use.

WiFi on sleep off (similar results with it on)
Here is my battery info, from settings and GSAM:

Drained 15% In 10hrs so you have 85% left and you think it's bad???how much do you think it's a normal drain for say an hour idle?because in your case it drained 1.5% with 30mn sot. I think you can tweak to drain something like 0.5% per hour

not sure if trolling :/

Maybe he means the battery went at 15 % and lost 85%

Turn Auto Brightness off. I've found that to help. With the phone brightness set to 50%, I've found it to be brighter @ that same setting than my old Note 4. At least it seems that way, and it's plenty bright. Love this screen!.

Here's my battery life and usage for 2 days.
It's great.

I'm guessing he meant 15% left in 10 hours. With only 30 minutes of use which would be terrible. My advice would do a factory reset and try again.

I believe I was on mobile data longer (she was mainly using WiFi today), but I feel like these are two completely different phones in terms of battery life. Is there seriously nothing wrong with my battery life?

Didn't you post this on Reddit and get the same responses?
