What is reasonable battery use?

I diconnected my phone from the charger, and it was at 100% at 830 this morning and now at 1130 it is at 56%/. This is after probably abotu 1-1.5 hours of browsing the web on my phone and configuring widgets.
I was wondering if that is normal battery drain? I have been flashing my phone quite a bit lately and it seems that the battery life is not that great. I have already recalibrated my battery as well.
Also my phone is overclocked to 1.3ghz.

You might want a second opinion but I'm going to say yes
If there is evil in this world it lurks in the hearts of man.

1130 AM? If so that is not good at all.

Not good at all, I am running Pinnacle 1.2 for 29. 5 hours since last charge and I have 29% remaining, that includes roughly 3 hours display on time and just shy of 1 hour phone calls.
Very happy with Pinnacle 1.2

Yeah 11:30 AM. Perhaps I should look into flashing another rom, although I have been very happy with Apex 9.2 except with this battery issue.

If you're on Apex, try going without the overclock and switching to the DarkCore kernel. That might help your battery life a little bit.

Did the phone feel hot?
What kind of sites were you hitting? White background? Lot's of Flash?
You've got three things that I see hitting your battery hard - the data transfers, the screen and the CPU usage. Depending on how your overclock is set up, I'd guess it's causing your CPU to use at least 30% more juice.
I can get days of idle time, but only hours of heavy use out of my battery. There are certain web sites and games that seem to suck the battery dry.

I am already running dc 3.1. I may try to undo the overclock.

Nothing really intensive. Mostly just xda forums.

I notice that I get much better battery life with i897 roms vs i9000 roms.

Sounds like you have an app running wild.

Well when my phone is on standby, I find that it drains at a reasonable rate. It is just when I use my phone that it drains fairly quickly.

You're doing it wrong.

29.5 hours? With Pinnacle 1.2 I'm getting about 8 hours with moderate use

Agree with jsfLip!
With moderate use, my Cap get out of battery in 8-10h.
Iam using Pinnacle 1.2, its standby status is quite good! 1-2% after 8h standby at night!
Please have a try!

Plus you need to caliberate your battery

Can't figure it out.
To: miztaken1312
I've tried different settings on my phone and have not been able to get your kind of battery life.
I recently flashed MosaicVI and using the JV6 modem. After using this modem I have been getting better results but not quite as good as your.
What I'm trying to find out is there any certain setting you have your phone in, i.e. only on WiFI, Auto Display, sound, Disabling Your data when not using it? I would really love to get this kind of results. I'm sure everyone else would to.
Oh, I've also cycled my phone battery 3 times everytime I flash a different ROM. Please school me up on how to get those results.
P.S. I tried to quote you and reply but me being new to posting comments did not let me.

Go to market and download "Data switch". You will see marked improvement to your battery life.

So is that the secret? "Data switch".

All it does is turn off data usage so your cappy is not using data for all the background services (synch and such). Its what I use when I want the battery to last and don't need a data connection.

4.2 Insane Battery Life! Project Roadrunner?

I don't know if it's just me, but I've been experiencing some insane battery life of my N7. I've gone about 4hrs on battery, wifi on, and battery hasn't dropped even 1%. Anyone experiencing the same?

Without a doubt. Before 4.2, my screen on time topped out at 5 hours. Now I can pull 6 hours.

Sounds off. No change at all in 4 hours? Can't be correct.

There is no way that's accurate... Power down the device and power it back on. See if it still says 100%.

YES I am having insane battery life as well. Still 100% and hasnt changed after 3-4 hours. Will keep observing

I noticed the longer battery life also. When a lot of stuff is running sometimes I will use the ES Taskmanager Kill app and when I did that there is more free memory than before and even when a lot of apps are being used there is more free memory than before also.

HOLY. Definitely inaccurate. I notice a small increase in battery life, but nothing that big. I get like 30 minutes extra.

I won't plugged my n7 til it dies.. See how long it'll last..

It's not strange on a devices with such a big battery to last 4 hours on 100%. Notice how the screen is rarely on?

That seems inaccurate but battery life is definitely better

That's what I was thinking. But since I bought the device, it hasn't done this. This is either a bug or battery life is extremely increased!
On 4.1.2 my battery drops 1% in 16 minutes of the same usage. This is definitely way beyond!
Still monitoring it.
Might as well play a few games to see what happens.

There is definetely a bug with battery readings.. It is likely drop more than normal , once it drops to %99.

Ok. I did a bit of NFS and it brought my battery down to 95%. Now to see if it'll drop normally.

I think your battery stats are jammed, I'm not seeing anything like that at best 30 - 40 minutes of extra battery, which is still nice. If your right your device is drawing power from the air around it

I had very simalar resdultsvwhen i flashed the ota url. But i flashed the factyory image the other day to start off fresh and no longer have reults like this. I'm not saying I'm getting bad battery... Far from it. It's just not the same as when i flashed the ota which is strange.

My guess is the update just messed up the battery app like it did everything else.Keep your charger handy so when your tab shuts down and it still shows 100% you can charge it.

Are you Serious?

really? i barely used the phone. everyone is turned off except wifi and i did not even use the the browser. this can't be real. only that much time and it's almost halfway dead and i barely used it. i know there have been battery threads before but man... how can it be this horrible. btw juice defender don't do crap, i've had it for the today and yesterday, was crap so i uninstalled. had brightness are low as i can without making me squint.

I've had relatively poor battery life as well... I went 12 hours with a recharge from 10 to 50% again before it completely drained...
I'm not impressed with the battery on this phone but everything else has been great.
... I'm starting to think I'll have to make my own Qi Charger for pant pockets... embed it in your pocket so whenever the phone is there it's charging. I'm seriously considering trying this to see if it's possible... if so, i'm doing it for sure. Or a carrying case with an extra battery and a Qi Charger... or a Qi charger dock for the car... you get the idea. Wireless charging shouldn't be the fix for poor battery life, but it definitely could help it.

Task managers mess around with Android's memory management and it is fairly well known that they usually end up draining more battery than they save. Try getting rid of it.
Also other people are reporting that the battery life gets better after a few days of using. Is yours really new? Im not sure how true that is btw.

Probably a combination of that task killer and a wake lock.

Install Franco's kernel. Battery life has been outstanding (1 Gmail account sync, 1 Exchange account sync, maybe 30 minutes of calls and 100+ texts a day; I have location services & Google Now enabled as well). I average 3+ hours screen on time and I normally end the day around 30% ...
I would stay away from task managers ... it's not that I know what's going on more than you or anyone else, but well established and respected kernel developers recommend against it. If these guys don't know then I honestly don't know who else does ...

just uninstalled advanced task manager to diagnose the problem, and so far it still remains, so the task manager is not that problem.

Yep...20-30 minutes won't tell the tale. I'd also recommend Brightness Toggle widget...allows a few extra steps (16 total, IIRC) of brightness control over stock, to fine tune screen brightness, often another culprit.

[Q] Why does android's standby time suck?

I've used around 5 Android phones (starting from 2.1 now up to 4.3) and for some reason, they all have a pathetic standby time. When I say standby, I mean when you press the power button and it turns the screen off and you don't touch it. Why is android the only OS that has this problem? WP, fine. IOS, probably the best one (only good thing about it).
I've tried different kernels, using no apps from the play store at all, turning off Google's location service, using greenify, and a bunch more. My battery still drops to ~70% at 4:00 starting at 100 at 7:00. When I briefly had an iphone and windows phone, I always was amazed at how my battery was around ~90-95% at 4:00. I know most people actually USE their phone during the day, so its probably not as noticeable.
Does anyone know the real reason for this? By real, I mean the deep down reason for this. Is java just a hog?

I think the main reason is the backround apps that are running. I used my old sensation just as a phone and so I deleted all the apps from it (Facebook, Viber etc.) and the phone lasted 5-6 days on standby with a 1 year old batery. Before I removed those apps I couldnt get 2 days on standby. I think backgrounfd apps in Android are allowed more "freedom" so they use up the CPU while on standby. That is my experience and opinion.

Yeah I thought that, but I said I tried it with no apps installed. Same thing.

Weird, I don't experience that kind of massive stand by drain.
If I turn my screen off or let it time out, my phone can sit for a almost a couple of days before it shuts down - sometimes two full days. This was true with my Nexus 4 and Galaxy S3, and now the One.
So I have no clue what you're talking about, generalizing Android like that.

i disagree
My battery drains 1% every six hours

I am talking about stock Android as well. I have had great battery life with my last three phones.

I've had no such problems with "android" in general. Some roms / apps yes. But after fixing those issues it was pretty much what would have been expected / what reviewers/other people get.
I would recommend getting something like gsam battery monitor and let it run at least a day and then post some screenshots. Maybe we can give some concrete advice then.

Must be something like 10-20 minutes, lol.
Regarding "always scanning", I dont think it's something that uses alot of battery. Probably even more battery friendly than other "location" services. Just because it labels WiFi as always on, doesnt mean it uses as much battery as actually being connected to a network. Personally, I don't care for all this location nonsense so it's obviously off. Regarding the location-based wifi, it's only smart if you don't know how to toggle WiFi when leaving your house, etc.

The phone maxes around 5-6, MAYBE 7 (I've never come near that though), hours of screen on time in total.
The 13% means that 13% of the battery used going from 100% to 72% was from the screen.
Tap "screen" in the list of battery usage and it will tell you how long it has been on.
This one's mine... ca. 70% brightness:
