[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] stoicism:
I'm glad I found this thread.

I've had the note for about 2 weeks. At first the battery was alright, no issues, but I hadn't downloaded any apps and was only using it for web browsing.

I have now downloaded some apps and am using it on my home wifi network only (no SIM inserted). For the last week, my Note's batter has been awful!

For example, I unplugged the fully charged Note last night and woke up this morning to a dead battery. It had maybe 5 minutes of use, then sat there all night...draining the battery. My Note is borderline useless like this.

I am going to install BetterBatteryStats and see what's happening in more detail. The problem is, it dies before I get a chance to even look at the Battery stats!

Thanks. That's very kind of you. But what we'd like to know is how did Frank make opera (or anyone else with any other browser) change the look of webpages -How to modify color scheme for browsers on Android devices. As far as I know, there is no such option on any Android browser. I had previously found a work around here, but it's way more intricate than I care to encumber myself with.

Incidentally, after poring over this thread I've come to the conclusion that battery life is greatly altered by the services that are turned on and off -many of which are efficient at self-monitoring while others are not very considerate of battery consumption. I personally always lose something in the neighborhood of 30-40% while I'm sleeping.

I've seen a plethora of battery tracking apps and widgets listed here, which should serve to help tracking where battery drainage is taking place the most.

However I fear that even with all that information available, keeping track of your services seems to be a handful. I can't remember to turn off (or on) some of the services (particularly those buried in some deep setting option). I personally use BetterBatteryStats & Badass Battery Monitor to see which operation is taking its toll on the battery.

I find that the "System Power Management" tool is just one tick option -but I have no knowledge of what exactly it's doing. Is there an app or widget that can help more readily shut down the extraneous services? ("The 14 Toggle Status Bar" mod comes to mind.)
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] manhattan212:
If you type "opera:config" in the address bar it takes you to a preference pane that purports to allow user edits to operaprefs.ini. In fact, it's a strange thing. It allows me to change all kinds of things except for the color of general text, which is always black such that a black background simply means the text becomes invisible. More details here

I wasn't getting the best battery life out of my note, until I monitored what was running by using the system app, I realised because I use adw launcher, touchwiz was still running in the background and all the Widgets and stuff that were running on the touchwiz homescreens were raping my battery, I removed all the Widgets from the homescreens ten froze twlauncher in titanium back up and litterally my battery has doubled!
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] manhattan212:
Thanks for the reply.

Does that mean that the solid streak in the Wake bar (while the screen and WiFi are off) is perfectly normal? It's not indicative of some rogue process having its way with my phone/battery?

I've never been able to survive one waking day, without having to charge my phone.

Admittedly, I may be something of a power user, in so far as WiFi is on almost all the time -if not, I'm using 3G.

I think as a general rule of this thread one with a problem should at least post screenshots of :

1. Default battery stats - both the general and detail view

2. BetterBatteryStats - Kernel Wakelocks, Partial Wakelocks (better to post all the screens)

3. CPUSpy Screenshot.

Ideally stats should be collected from a freshly charged and rebooted phone.

You had me googling cpusLy up and down the internet! I couldn't find anything. Now I understand it was a typo. In retrospect, it's an obvious one at that, considering the placement of the the L in relationship to P... But google didn't offer CPUspy as a correction for my search, and it hadn't occurred to me... :D

In any event, before I could find out what CPUspy was, I started having some rather horrid heating issues -I think it was caused by Advanced Task Killer (ATK). So I decided to wipe/factory reset & wipe cache, re-installed [deodxed & tweaked] stock ROM -and I only have dark theme by nobnut installed. I'm going to hold off on BetterBatteryStats, Badass Battery Monitor, et al. for now.

What is Kernel use if I might ask. It's using 38% of my battery power.

To anyone who doesn't want to install roms or root their Note, go to market and install Juice Defender Ultimate and Easy Task Killer Advanced. use Aggressive on Juice Defender and default settings on your Task Killer. it reduces my battery usage in half.

[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] ghaza:
May i know how you configure your juice defender. I have JD ultimate installed but when the phone screen is off, my wifi and data will also goes off. I will not be able to get my whatsapp message or my autosync will not run when the wifi or data is off.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] manhattan212:
Not when you first suggested it to me.

:D
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] manhattan212:
I surmise that this is the trade-off.

If you want your wifi and data on at all times, then your battery is going to suffer the consequences. There will be applications besides messaging services (like whatsapp) such as update checker and auto-sync that will be active in the background -even whilst your screen is off. This will inevitably consume battery.

What many users in turn are willing to do, in order to get more battery life out of their device, is to have their phone go into a deep sleep in which you essentially have a phone that can receive calls & regular sms text messages -until you activate the screen for whatever operations you intend to do.

This is how I understand automated monitoring apps to work. They essentially equate screen-off to semi-off state for the rest of the phone.

There may be methods or applications that try to find a more balanced approach -or services that may allow you to view or more closely monitor what's happening, so that you can determine what to do and how to deal with active processes that may be taking up your battery juice. Most of these monitoring applications (and often, even the required steps) require root access in order to track and/or alter internal services.

At least that's how I understand it.

Any corrections or modifications to my interpretation would be appreciated.

P.S. I personally don't trust most of these monitoring & tweaking services to be effective; in fact I often find them to be detrimental with unexpected side-effects.

Hi, I'm not asking for my personal use. I'm just asking what functions the Kernel has. I get good battery life. I'm at the end of my work day and I'm at 60% still, but as I said in my post, I'm just wondering what the Kernel does, because it has a lot of processes, that's all. Thanks though :)
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] manhattan212:
Looking at your signature and post count (and thanks meter) you don't appear inexperienced. So I assume I'm misunderstanding your question. But in the event your question actually is "What is a kernel?" an answer that can be easily found by searching the forums or even just Google at large I'll write a quick analogy derived from a definition I once happened upon, here.

The ROM is the Car.

The Kernel is the Engine.

Themes are the chassis/paintjob.

MODS are as the name would imply modifications to different parts (speakers, antena, spoilers, etc)

Apps are also self explanatory but in keeping with the car analogy, they would be a GPS system for your car or maybe even a new radio (notice the closeness of relation between MODS and Apps).

For more explicit delineation of what each individual component within any given kernel, you need to read the update log for the particular kernel in question.

If you mean you want to know what exact processes is your kernel causing to happen, then you need to use some of the monitors previously mentioned throughout this thread.

And if I've missed your question... maybe you can consider rephrasing it.

Might just be me but, I really dont understand why you would buy and carry around a 5.3", top of the line phone, and turn everything that makes it great OFF, so you can get a couple of hours more out of it. I get the dramatic cases where some apps are depleading the thing... But any other case I really dont see the point. I cant get more than 10 hours out of it (juice defender ultimate and advanced task killer up and running). So I turned to the obvious solutions, buy another battery...

might not have the best battery life, but I have the best user experience, everything set to run as it should be... if you are sooo worried about battery life , buy another phone, this is a battery hoging piece of tech... that´s why Samsung put the biggest battery they could fit, but they NEVER promised even decent battery life...
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] manhattan212:
I think you bring up an interesting point. I am inclined to agree, in so far as -I also don't see the point of gathering the five lions unless you're going to merge into Voltron and form the blazing sword.

However, I now have to sort of disappointingly ask myself did I buy a phone or a tablet? I thought the phablet would be the best of both worlds, but it's actually not. It's a little too small to really be a tablet and the battery life is insufficient for it to be a communication hub, for extended periods of time.

To me the note is closer to an unfulfilled promise... Showing the potential of what's to come, but isn't here yet.

As it stands, I'd rather have a small tablet, like say a Galaxy tab 7.7 and a small nokia phone rather than the note and another phone or even the extra battery. The idea, for me, behind the Note was to be a bulk reducer -sacrificing size in both directions for the ultimate compromise. In the end I underestimated how poor the battery would perform with less than one day of idling (in my case; I know some get more than one day, but for me the ceiling seems to be at 18hrs under very low usage).

But I am hopeful that the future looks promising. I just hope they don't forget to include the pen, as that was one of the key factors for me. Although the pen turned out to be more gimmick than anything, on the note (for me), not just due to the lack of application support but also due to Note's smallness.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] sibere:
OMG!

On IDLE only my note could last days! I'm killing it in 24H because I'm using it a lot.

If your phone was idle you should get most of the time on deep sleep.

I have noticed something on my phone:

- It enters deep sleep no matter what when I'm home on my home network and my own wifi

- It fails from entering deep sleep from time to time when I'm abroad, on a foreign GSM network and after connecting to the hotel WiFi network.

Dunno if it's related.

What I would say is: Everytime you use your phone, start CPUSpy and turn your phone "off" (standby mode). Wait for a few seconds, and turn it on again. Check cpuspy stats (menu -> refresh) and see if it's entering deep sleep mode properly by looking at the deep sleep timer increase. If it's OK, turn it off (standby) again and do again the same next time you use your phone.

That way you'll may be able to spot the issue as soon as it comes and sort it out.

If you phone doesn't enter standby mode, restart it and after a full restart, do again the procedure to check if it's entering the standby mode.

Hope it'll help you to sort out this battery drain issue.

I get the general idea that something is keeping my phone from going into deep sleep despite the 3G and WiFi being off. But I'm not really sure what all these processes mean, what they're doing, or how I should deal with them.

The screenshots look inconsistent. Bbs shows less than an hour since full charge while cpuspy shows 12 hours, built in battery meter shows 6. Really hard to say like that.

Here's what i'm getting -

total screen on time - 5 hours 1 minute.

I am thinking that the Wifi is a total battery hog, because when I browse I browse in a VERY battery friendly green on black background mode on opera mobile. And yet, look at my graph.

I'll also note that for now, I am getting ultra aggressive in terms of battery saving mode, i.e. black backgrounds, etc.

I will run some more battery tests tomorrow.

I am testing things by setting certain things on for 7 minutes or so, then seeing the ma droppage in battery monitor widget pro. (which logs things every 5 minutes so you need that 'buffer')

I'd be very interested in seeing battery graphs of people who are getting really good battery life.
