Disable 'low battery' screen activations - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

I use two batteries a day due to my long train-commutes to and from work. That means I will go past the 15% and often 5% low battery warning prompts. The prompts very often come up when the Note is in my pocket or the screen is otherwise not on. Turning on the screen twice to warn of a low battery is kinda like sounding foghorn each time silent mode is activated. Sort of undoes itself. So I'm out for a solution. Any suggestions? Thanks guys.

I am with you. I hate that warning. I have three batteries myself (including the stock one)

There's got to be some root app that let's you change up the percentage when the warnings occur. Can't you do that on CM9?

[Q] Remove Battery Full Visual Alert

Hello. Has anyone figured out a way to remove the battery full visual alert? I use Timeriffic to remove the audio notification. I have a Samsung Dock and insert my phone into it every night when I go to bed. This puts the phone into DeskHome mode which I like. Then, in the middle of the night, when the battery gets to a full charge it shines like a beacon and stays on until I click the button to shut it off. My wife usually gets mad and flips the dock over. So my question is.... Can I turn off the visual notification of a full battery? Or make it so it doesn't kick my screen on and keep it on? I am not concerned about leaving my phone on the charger all the time and I am not worried about the audio notification.
It's possible, but...
Yes, it's possible to eliminate the popup notice & sound effect. However, it's very complicated to say the least. It involves editing the services.odex and android.policy.odex files.
What I haven't been able to do is track down what exactly causes the LCD to come on when the battery is fully charged. If I could figure that out, I could totally eliminate the whole thing.
FYI: It's the DeskHome app that keeps the screen on once the "battery is fully charged" notice is sent through the OS. If you don't have that app running, the screen would come on, then go off just as though you hit the power button but didn't unlock the screen.
Thanks! I tried that last night (not running DeskHome) and it worked! I would love to be able to have more control over deskhome to eliminate the full battery alert, but oh well.

[Q] Can't change brightness when battery low

When the battery gets low (not sure what percentage), the screen dims and there is no option to turn up the brightness. Is there a way to change this on a rooted Tab? Is it possible through the development API to adjust this, so that it can be implemented in an app?
Charge your battery. It comes on when like 5% remains anyway.

It comes on when there's 15%, as I got two more low-battery notifications after that. The problem is the tab is almost unusable at that brightness (especially outdoors or in a car during the day) and since I ran it for two more hours with Angry Birds and YouTube, I've lost two hours of battery life period. If it let me adjust brightness, I could at least use it until it depleted.
There has to be some way to change this, even if I have to root it, change a config file, or write an app to let me change it. Does anyone know how to modify this setting?
Genuine question only because it wasn't mentioned. Auto brightness isn't checked right?

Brightness was checked the first time, the second time it was unchecked and all the way up.
Did you notice, the backlight for the four haptics buttons at the bottom will also turn off at this point, which makes them impossible to see when it's dark.
You need check then uncheck auto, you be able to change the brightness
swyped from a galaxy far far away...
I'm having the same issue. I have a battery issue where my tab displays 1% when I have 20% or more remaining. Was wondering if you found a fix to this.

[Q] Weird battery consumption

Hi guys. Last night, for the second time, something odd happened to my note. I was at 39% battery at about 1 o'clock in the night when I went to bed, and this morning, for the second time, the phone was dead. No battery whatsoever. The first time I didn't worry about it, but now I'm thinking about taking it to warranty.
I had Wi-fi off, 3G-off, no apps in the background(except basic services and avast) , I don't use sync, I have a custom battery saver (same settings as the default one, except I always keep GPS-on). I have XXLC1-ROM (stock - rooted). I have frozen some useless processes with Titanium Back-up(the mini-diary, AP-mobile, Social-hub, Readers hub). I also used the app Battery Calibration when the phone was at 100%, the one created by Nema. Should I be worried and take it to warranty ? It doesn't happen a lot because I usually let the phone charge overnight.
Added a screenshot of battery usage: http://www.picz.ro/show-image.php?id=7873c3532838d733974b56544cc222f5
Install betterbatterystatus app and monitor which app or hardware draining the battery particularly. So that you can monitor and control as wanted. You don't have to take to warranty. There are lot of threads regarding this topic, surf it, lot of ppl got relived from this same problem.
Did u turn off fast dormancy

dude. uninstall avast first of all then do a restart and test it that way
My note went from 98% to 'dead' in 6 hours with Battery monitor showing 'Kernel' as the cause.
I had missed seeing an SMS arrive and the 'preview' of the message was on the screen. This seemed to be the cause.

[Tutorial] Battery saving techniques

So yes this Phone's battery unfortuanatly is not well at all.. but here is how i managed mine to last a day without charging. Let me also say im a heavy user also. I text A LOT and always pull out my phone in class play a few games to pass the time or just browse my phone. So this does work for heavy / light users.
Go to Wifi/ menu / advanced and click never on Keep wifi on during sleep.
Go to settings/ Location access - Switch to off
For your brightness it will be on Auto switch that off and put it almost to the lowest as you dont really need it high just kills the battery.
- Go to the App store and download Easy Battery savor. When you access the app choose intiligent mode. It really helps !
-Dont ever use live wallpaper it just drains it so fast.
- DOwnload Faux App It really helps (Faux kernel Enhancement Project) Once downloaded go to CPU and set max clock to 1.35 instead of 1.5. it will still be buttery smooth and it will drain the battery less.
Also I am using the Franco Kernel - nightly #53 which in my opinion really helps !
- Try to turn off the WiFi usage as much as possible and you will see a huge difference.
That's all from me guys. By doing all this my battery significantly improved and lasts about a day now.
Anyways if you have better solutionson how you manage your battery and how you extend its life.
- post pictures
- post the apps you use
- post everything !
Thank you !
I use harsh. Whenever I don't game, I lower the max freq to just 810mhz, ondemand, row, mpdecision on (as harsh recommended) and it's still buttery smooth, and of course battery life is incredible, and I also do check the Disable HW Overlays and Force GPU in 2d rendering. And since no kernel controlling apps are needed, my phone feels cleaner too I can't upload battery stats yet as I'm in an area with only edge connectiom and I hate using slow internet connections

A couple of things I noticed with this. The first thing I notice is, in two of your screenshots, you appear to have mobile data disabled completely. The second thing I noticed is that your final screenshot shows 24hr 52 min on battery, yet according to your clock, a it should really be a total of 33hr 6 min since unplugged. Your first screenshot shows 88% battery remaining with it already having been unplugged for 7hr 35 min. With that screenshot showing a time of 3:11pm, that would mean your phone was unplugged at 7:36am. If the phone was unplugged at 7:36am, then how is it only showing a total of 24hr 52min at 4:42pm the next day? It should be showing 33hr 6min. That's an odd inconsistency there. All in all, even with the data that is showed in your screenshot, it shows very little use as phone idle and cell standby are both in your top 5. Your screen was your highest drain, yet there isn't anything else there accompanying it. I could be wrong, but it seems to me that all you did was keep the data turned off on your phone, and connect to wifi where available. You turned your screen on, but didn't really do anything with the phone besides having the screen just on. That said, even stock with no changes, a person can get 24 hours on a charge if they're disabling their phone and not using it.
Interesting tips however I have a few points:
Your first tip suggests having WiFi to Never stay connected during sleep. I am part of another Android forum which deals with tablets. We tested this feature as with a tablet, you are likely to leave it for hours on end before using it again. It was excellent if the tablet was not touched, however we noticed that it significantly increased the battery drain if you were regularly switching between sleep and using it.
Agree with the second but don't throw away practicality, use Location settings when they need to be use, not just turn them off and don't use them.
Leave it on auto-brightness dude, why ruin the nice visuals of a fantastic screen by having it so dark you can't see it? I only ever use lowest brightness when its dark or the battery is nearly dead.
No idea about the battery saver.
I definitely disagree with this. If you use 3G permanently, like I do, then turning on WiFi definitely reduces battery drain. I don't turn off data ever, so switching WiFi where possible is quite a useful battery saving technique.

His solution is to turn off connectivity and functionality on the phone. That defeats the purpose of even having the phone at all.
That said, I think a safe UC of maybe 200MHz can have a difference, but to me, it's all about enjoying the phone and the phone experience. No need to screw with it
Don't do the wifi feature. It will use more battery because it will constantly have to reconnect to the wifi connection every time your phone comes out of sleep mode and that will consume more battery.

Just curious, why did you buy it then? Personally, I'm leaving everything on because I bought the phone for the looks and usability.
And yes, the phone lasts me all day while using it for everything including emails, conference calls, web browsing etc.
I've set up profiles using the Smart Profiles app to quickly turn things on and off at will - hit CAR and bluetooth/GPS turn on, Wifi turns off. Hit HOME and the reverse happens, etc.

Same thing here..but I use scripts When I'm in school and all I need my phone for is some tethering and music, I activate my script that sets the max freq to just 810mhz and I undervolt an extra -50mv from the stock undervoltages of harsh, but when I'm out and away, I enjoy the full 1.5ghz quadcore beast trapped inside my pocket

Don't get me wrong, it's useful to have a decent battery life, but I really don't see the need to turn the device into an expensive brick. My suggestions, which may or may not be better than the ones in the OP, but they seem to work for me on every Android I've come across without screwing with undervolting etc:
1. Turn Auto-Sync off, or increase the duration between each sync. On my old phone, the phone would use Auto-Sync every hour or so which totally killed the battery over the course of day. I turned it off and would sync it manually (taking all of 15 seconds) on a Friday. Made a huge difference, although simply increasing the time between syncs is just as effective if not more so as you still save a bit of time (might opt for that myself :good
2. Use Inverted Apps on SAMOLED, Don't use Inverted Apps on IPS, white colour uses more battery on SAMOLED, but a lot less on IPS :fingers-crossed:
3. Get yourself a Toggle-based Notification bar, you will remember to switch off your WiFi when walking around in public. To that end, switch your WiFi off unless you are connected to a hotspot, the constant scanning will drain your battery and depending on the interval may take quite a large hit over the course of a day. If you rely on WiFi then maybe increase the scan interval time.
4. Turn off all mobile networking services when in a known signal blackspot. e.g. When work pays for us to go to a hotel on the Welsh border in Cheshire, there is absolutely no signal guaranteed unless you go to the end of the driveway, so I turn off all phone services unless I am there. Your phone will drink your battery very quickly otherwise, guaranteed. The easy solution is to use WhatsApp, switch your phone onto Airplane mode then turn on WiFi and connect to a hotspot (if they have one available, hotels usually do). This is surprisingly low on battery consumption.
So basically, just leave my phone in my pocket and not use it. Okay. Gotcha.

My battery life is amazing. I guess it just depends on what you compare it to. I had an evo 3d before, and my 3d would be dead by noon without even turning on the screen. My work blackberry lasts 5 days with fairly heavy email usage.
My N4 though, I use it fairly often for browsing, occasional calls throughout the day, streaming audio, this and that. After 12 hours of use I am still at 60% usually. From 7am to 5:30 (typically when i get out of work) I will be at 70%+
Not sure why people are so bent out of shape about it...
On my 3d if I ran facebook app or any stupid **** like that it would kill my battery like i didnt even have one.
Here's another idea get a job or pay attention in school. That will save battery life as well. I have literally seen people stare at a screen without doing anything with the phone, just because they are so obsessed with it being in their hand
Oh and my Sig does not represent the nexus in the mail

[Q] Blocking Mode Killing Battery Life?

I've been having problems with my Note 2 for a while now, in particular my battery would drain about 30% at night when I'm not using my handset, apart from it automatically checking emails occasionally. During the day, battery life is much as I'd expect. I get through 30%, but with reasonable usage.
I think I've pinned it down to the Blocking Mode. When I don't use it at night, battery usage is less than half of previous usage. One other person has confirmed a similar experience over a short period. I'm running Baseband N7100XXDLK7 (but this also happened in the previous ROM too). I'll repeat this for a few more nights, but I'd appreciate it if anyone else could try blocking mode and see if this is repeatable. (I had disable incoming calls, notifications and LED indicator on).
Oh, and any ideas how to cure it? (apart from not using Blocking Mode?)
Many thanks
R: [Q] Blocking Mode Killing Battery Life?
Did you check, using cpu spy, if your cpu is able to go in sleepmode while screen is off? If it doesn't, then maybe there is some app that make your note awake and working when it shouldn't...
