Battery savings guide - Nook Color General

Hello, i use Dalingrin's kernel (6/30) and CM7 nightlies (121 currently).
Sometimes deep sleep is nice for my battery, sometimes it doesn't save energy.
It's life but i need a few days between battery charging.
so i decided to add a few workarounds, here they are:
1. Airplane mode everytime + wifi on/off when i need it. Only ten seconds to activate/deactivate with CM7 status bar.
2. Battery widget monitor: it enables history of battery consuming. Very good to act that deep sleep is effective or not.
3. uninstall applications which sychronize when nook should be sleeping: K9, DSPmanager, hotapps, appbrainz.
3. Advanced task killer pro: Crazy mode when screen is off. Very nice for last applications.
Of course, you are welcome to comment those tricks and to add some

I guess it depends on use, but I'm on day 3 on a charge, running at 47%. I just have the screen at 15% most of the time, and I don't disable sync. I mostly do reader, email, internet, so that might be part of my success.

1 is probably not a good idea, since sometimes Airplane mode sticks.
2 has nothing to do with saving battery, but okay..
3a does nothing if there is no network connection (assuming sanely written programs)
3b is stupid and shouldn't ever be used.
You want to save battery? Turn off wifi when the screen goes off. You can do this automatically with Setting Profile Lite or Tasker, probably some others. I've found that the wifi sleep setting doesn't do anything for me, I can continue to ping the NC for 10+ minutes after the screen goes off so clearly the wifi is still up.
And watch Spare Parts partial wake locks and see if you have any misbehaving apps. I find that Maps with Latitude enabled misbehaves without a network connection and constantly is trying to update or something, so I cleared data on Maps to get out of Latitude on that device. CPUSpy will also show you how much deep sleep is ongoing.
The NC is going to use at least 10%/hr at low backlight doing simple tasks, I've seen it use up to 25% overclocked playing games.
While asleep it uses about 1% every 3-4 hours. Could probably do even better if you don't have a boatload of apps and widgets like I do.

Grab "Where's my Droid's Power" or whatever the application is called, and see where all the power is going.

He said the battery widget is to see if it is asleep, and see what the consumption is like.

Hello,
You are right about battery logging.
i have to test the two applications you mention both:
1. "And watch Spare Parts partial wake locks and see if you have any misbehaving app"
2. "Where's my droid power".

Battery drainage on Galaxy Note

Well, hi guys, I have been a member on this forum for quite some time but due to bad memory I forgot my account so I made a new account, that's not my point of this topic.
I bought a new Galaxy Note and I simply love it, awesome phone, but I noticed something wrong. Yes! the battery...
My battery simply dies in 2 hours of usage (videos or listening to music while playing Wordfued)
I want a solution for that, I have my warrantry and all, shall I demand a new battery or something? I'm Swedish by the way.
And I'm sure you'll ask me about flashing a rom and root it.
I know that would make the phone faster, but I'd rather wait for the official ISC.
Only if I can do both of the things at the same time, if so then I will flash, please do read everything so you can watch from my prespective, thanks in advance.
That's definitely not normal. I get much, much more usage doing the same, so I would definitely try changing battery first and then changing the phone as a second option.

Fully agree.
I would get 4 to 5 hours of continuous use, I reckon. Some people report more.
I think the problem is with the battery. you can try this :http://www.amazon.com/2600mAh-Batte...I84K/ref=sr_1_4?ie=UTF8&qid=1329085625&sr=8-4 . Just bought it and it give me like 6-7 hours of watching videos.
Thank you for the link. I was looking for a better battery. I home to find a vendor that ships to France though.
Thank you

Thank you my dear sir, I'll take that as the second option, I'll try getting a new battery since my warranty is vailed for 2 years.
Thank you though
No need for an extra battery or extended battery.
Install juice defender
Leave brightness on auto
disable 3g (it is on by default I believe and I noticed a big savings on batt %)
disable auto screen rotate(optional)
my phone is @ 44% left , lasted 11 hours 2 minutes , This will last me another 5-6 hours.
Did about 1 hour of gaming (myth defense)
30 min browsing on wifi
45 min on tapatalk
1.5 hours on the phone
1.5 hours streaming music to my desktop via kies air
I had posted something like this before...
1. Flash and test different kernels in case of battery drain. Some are easier on your battery than the others.
2. Use Titanium Backup to freeze or uninstall crapware. This list is a useful guide as to what can/can't be removed from your system: https://spreadsheets.google.com/spr...SENVeXlqUm5vV0E&single=true&gid=0&output=html
3. Set Brightness to low value, disable autobrightness
4. Disable or scale down vibration and haptic feedback
5. Automatic syncing of your accounts is battery consuming. Sync manually if you can
6. Set screen timeout to 15 seconds
7. Disable fast dormancy (dial *#9900# and do it from there)
8. Don't keep your WiFi/Packet Data on all the time. However, if you must have WiFi on the second you wake up your phone, go to Settings/Wireless and Network/Wi-Fi settings - once in Wi-Fi Settings, hit the menu button (the bottom left one), choose Advanced/Wi-Fi sleep policy/When Screen Turned Off. This way your connection will toggle on/off depending on your screen on/of state
9. Disable location services via wireless networks - are you travelling that fast that you need those?
10. GPS is heavy on the battery, therefore use it sparingly
And don't use Juice or any other battery 'defenders': they keep running in the background and consume your juice by trying to save it. Not to mention other problems they can (and often do) create.
Hope this helps.

I have found this too, although YMMV.
I use Llama (Location Aware Mobile App) to turn things of and on when I move about. I seems to work very well mostly:
1. Got rid of useless apps, and kill all listeners on new apps so they do not pop up (require root)
2. When at home or work, WiFi is on but sleeping when screen is off (this is the one that fails most often - need to monitor), data is off (to prevent use when WiFi is sleeping).
3. When out and about, data is on, sync is off (to save mobile data & battery).
Like this I can get very flat battery level graphs when the phone is asleep, which is what I want.
When the phone is awake, the only thing you can do is turn the screen auto orientation off (I use Llama to turn it on for certain apps), and keep the brightness down, and use dark themes for everything, really. Turn WiFi off when not using it would also help.
I just wish they had made the battery larger & thinner (as someone else said) so that a thicker battery could have been more effective still, like triple the capacity
Try disabling GPS, wifi and data connections when not in use to save battery. Also you could flash the latest abyssnote kernel. It has absolutely amazing battery life.

wow turning off data and WiFi really helps battery life

I've always had my data on in all my phones.. .I got fed up of the gnote's battery life so I decided to turn it off when I was not using it and God I was surprised, I watched a whole movie and played that train game and I lost only about 15 -20% of my juice.....
so today I turned off my data and WiFi before i went to sleep and when I woke up 6 hours later I had only lost 1%
that has never happened before...
Uploaded with ImageShack.us
wifi has been known to be a great battery hogger on the note, interestingly enough it should be the other way around
as for the data, the phone works extra hard in lower signal areas to boost reception, hence drinking juice
I always disable wifi and data when I'm not using them.
I use the Go Power Master widget to switch between different profiles I have set up for wifi, mobile data, wifi with autosynch and no data.
There are other widgets that do the same thing. Just saves you having to toggle each setting separately.
If I stay connected with wifi, it's not too bad, but if I move out of a wifi area, and leave it on, it seems to drain battery faster (I'm guessing because it keeps rescanning for connections?).
I have somwhere describe this
Any way you will find this solutione better.
Use phoneweaver, you can describe the time, it will stop data at defned time, as well switch on too at your describe time. So if you set data off time just after your time to sleep, N switch on time just b4 your wake up time, you even need not to bother do do it manually
same way this can be triggered by location too, you can switch on/off data/wifi at perticular place.
And there are lot action you can set.
agree to rechlum if you are connected to wi-fi is consume less battery thn you are connected to net with 3G, N keep wifi open with connected to data is draining battery too fast.
could it all mean that I wasted a lot of time trying to reduce my battery consumption with WiFi on?
so far by disabling the unnecessary apps strartups (Autorun Manager) and turning off non-essential syncs I was able to get down to ca. 7mA (Battery Monitor Widget estimates) in standby mode, BUT only when WiFi is off.
When it's on, the power consumption stays at ca. 60mA in standby mode, which is something I cannot comprehed - using CyanogenMod on my previous device I was able to stay below 15mA regardless of WiFi state.
Turning off data is pretty stupid. I don`t about you but my phone is actively working in the background.
checking email every 5mins
gmail syncing

twiter syncing

3G data monitoring
weather updates every 30mins

sports scores updates every 1min with your choice of espn, score mobile, fox sports...
bottom line is gotta use a smartphone as a smartphone. With data turned off notifications are not happening.

If I know I'm not going to be looking at my phone for a while, it's not much use wasting battery having wifi or 3G turned on.
I'm a teacher, so I often have 3-4 hour blocks of time that I won't touch my phone.
I just turn wifi or data back on when I'm ready and my updates still come through when I'm ready to view them. Any updates that might have come through if I had left data enabled, I wouldn't have seen any earlier...
If I'm watching a movie I'll often switch off data because I know I won't be looking at my phone for 2 hours.
I don't see how conserving the battery is "stupid".
One could argue that leaving data enabled when you aren't in a position to use it is "stupid"...
Just out of curiosity, is there some pre-made application that allows me to turn data and wifi off after 5-10 minutes after then screen has been turned off and then turn both back on when the screen is turned on? Or should I just code it myself?

there's an option in Settings / WiFi Settings / Menu key to turn WiFi off when screen is off,
besides that there was one to do exactly what you need, but cannot remeber it's name, if you don't find anything satisfactory then try Lama - it has quite a large range of location-based triggers
Leaving wifi on when you're not using is awful. It completely prevents the phone from going to deep sleep.
I get awesome battery life simply by leaving wifi on only when the screen is on. My battery ranges from 18 hours to 1 day and 23 hours, depending on my use (temple run )

Greenpower will do exactly that. You can set it up so it turns off wifi and 3G/data after a set amount of time after turning off the screen and turn it back on when the screen is turned on. You can have it sync once every n minutes/hours so you still get Whatsapp, emails and other stuff without having to turn on the screen.
It's working like a charm for me, before I used to lose 15 to 20% every night, now with the same usage I've only lost 30% in 67 hours.

Everybody has different needs. If you need all this and to be aware of what i going on in your no-doubt busy social life, then you can do this.
On the other hand, it is utterly useless if you are not going to pick up the phone and see what the weather is (instead of looking out the window) and who is doing what on Facebook (or writing things in Facebook instead of actually doing things) as soon as it beeps at you. In those situations, turning of data will save battery with no loss of information.
Personally I love a 'pull' digital life, rather than a 'push' one. I have far too much to be getting on with to be constantly hassled.
Of course, in actually writing this, I am proving myself completely wrong, but what the hey?
I only care about my Google+ account and my e-mails, everything else matters only when I personally decide to check it. As such I've set my phone to turn data back on every 30 minutes, sync e-mails and Google+, and then turn data back off again.
I use Timeriffic (free from Market/Play) to disable Wifi/Data etc based on time of day.
I don't really care about emails when I'm sleeping!
A must have application IMO.

If you havin' battery troubles I feel bad for you son...

I got 99 problems but my battery life ain't 1.
How to get the best battery life out of your Nexus 5
1. Location Services : If you are not in a neighborhood with a lot of wifi spots you will most likely feel this draining your battery life. Under settings make sure that Location Services is set to battery saving and not High accuracy.
2. Widgets : Weather widgets, games eat battery by constantly fetching information . Check the settings for these widgets and make sure they are using wifi and not updating the weather information every 30 mins or so. I keep my settings to update weather information every hour to keep it reasonable. The Gmail widget sometimes eats your battery too. I removed the widget and used an icon in the dock at the bottom to check my email.
3. Restart your phone : Sometimes residual processes from closed apps could cause issues. Restart your phone if you haven't done it in a while and it should clear up any unnecessary things.
4. Keep wifi on during sleep : I made sure my phone uses wifi even when its sleeping. 3g / 4g eats the battery like crazy if you turn off wifi when your phone sleeps. This should be a default setting as pointed out by some users. In my case it had been changed probably when I was tinkering with the phone. You can find this setting in the Settings -> Wifi -> advanced -> Keep wifi on during sleep.
You can also use apps like Greenify , Tasker , and Llama.
5. Don't use Automatic Brightness : Turns out if the sensors are constantly looking to adjust brightness it takes up more battery. I set my brightness at around 60% and it works just fine throughout the day.
6. Use wifi over 3G/4G/LTE if possible
7. Switch off wifi when using Data: Android doesnt switch off your WiFi when you use data because Google wants you to use it for Locations and help build their database of networks.Switch off WiFi completely when using data to save a good chunk of battery.
8. Turn off Vibration on touch : Typing uses quite a bit of battery over the course of a day. Try switching Vibration on touch off.
9. Use Franco Kernel: : This will require rooting your device however it makes it a lot more power efficient.
10. Turn down the Facebook refresh rate : Make sure it updates not very often( every 3-4 hours) or never. IMO your phone is better off without Facebook or any other battery hog social networking apps.
11. Greenify: Works with and without root. Use Greenify to hibernate apps when they should not be running in the background. This is best used for games that fetch information about deals or daily events (i.e. Battle Nations or Real Racing 3)
Feel free to add anything to my list.

4, 6, and 7.. it would all depend on your signal quality. i get MUCH better battery life on lte than on wifi. and i mean much! i get 5-6 hour screen on time without doing anything special. on wifi i get an hour to hour and a half less. so the wifi thing is just in your situation, and not for everyone.
9.. there are better kernels than franco kernel. and on top of that, kernels have so little influence on battery life. battery life is mostly about your personal use, your personal setup, your choice of apps used, and very much on the quality of your phone/data connection. everything else has very little influence, including kernels.
3. This I agree. I've had super strange battery drain if I don't restart the phone once in a few days. I refuse to believe its a bad app as there are no wakelocks, seems to be more of a phone idle battery drain or radio drain.
4. To be honest, it depends on the WiFi network. Some WiFi networks (typically at universities) have a strange and outright horrible battery drain the moment you connect to their network and leave the screen off.
6. Again to not repeat what I said earlier, I get better battery life if I connect to LTE instead of my school's WiFi. Download speeds over LTE are 2-5x greater than my school's WiFi, so race to idle may be happening here.
7. Most android phones today have minimal battery drain with WiFi left turned on. But it doesn't hurt turning WiFi off if there are many weak known WiFi networks around you.
8. Not sure how much you'll save, I don't even recall much of an increase of battery with this off. YMMV situation I suppose.
9. I've had better battery life with other kernels. Again it's a YMMV situation.
Not a bad guide really
Another tip is that if Google Play services keeps your phone awake for a long time, revert Google Search to an older version, reboot the phone. The wakelocks should be drastically reduced.

Using Nexus 5 with:
CyanogenMod Nightlies
ElementalX kernel
1d 2h 9ms on battery / 2h 17ms screen-on time / with 38% remaining!
Good information! ?
Only thing I'd say is to just remove the part about kernel completely. As said above, kernel makes little difference. I get 24 plus hours and 6 hours screen time on any ROM or kernel. It's all setup and usage.
Nothing new here. Good for noobs, but most will have done this already
I have found that turning location off completely has helped my battery life tremendously. While I was barely able to make it through the day before, now I can easily pass by with 40% or something and light usage. I've tried other things but nothing has improved my battery life as much as turning location off.

T700 Tab S Standby Time!

My Tablet lasts 2 days before its totally dead with ZERO USE!
Updated to 5.0.2 as i hoped this would fix it. No change
Lost 10% battery while in power saver mode in a few hours!
Lags all over the place when scrolling, the play store is horrible when scrolling apps.
Right now my S6 has better standby on 4G and more life in use than my tablet has with no use!
Any ideas?
Can't speak for Lollipop, since staying with 4.4.2 and disabled auto updates. I only lose 2% in ten hours and the best Android tablet I have owned- especially in regards to low sleep bleed.
clearly something is not right have you factory reset it? That would be the first thing to make sure no apps are doing anything weird.
I flashed a whole new OS... should i wipe it?
You need to install a wake-lock checker, it will show how much time your tablet is actually in deep sleep mode, which uses the least amount of power, mine shows 97% time in deep sleep.
Some application can keep you tablet from going to sleep, alarm clock and sync can also, and apps/software you downloaded.
Do you get still get major battery drain after a reset, dont install any software/apps and the charge to 100% and then leve it for a few hours and then check how much power you have lost.
John.
Over an 8 hour period (avg) with wifi on, my screen brightness set to 10-20 range (that is the brightness I prefer on my tab s), and with greenify I lose maybe 1-2% battery. You definitely have some program or service constantly running or waking up your tablet, and due to the interactive governor that samsung uses your tablet wakes up at 1.9GHz each time to be more responsive/save battery by handling what ever is needed as fast as possible so it can sleep again. Unfortunatly if some app keeps going "hey, hey, I am here, I need you tablet, hey, hey, ect........." that battery saving governor will murder your battery.
So i wiped and its still 48 hour batter!

Losing around 30% battery over night idle.

Do you need to have your wifi and sync on for business or something, if not turn them off, of use an app to to mange them like the free juice defender ect.
Just install it, make sure it is enabled and then make sure the icon is on your taskbar so it has not been killed, and them forget about it for a week and see how it goes.

for some reason on this tablet, wifi murders battery in standby. if you turn it off it lasts much better... but this tablet and this tablet only, leaving wifi on kills it horribly. but problem is, when you wake it for teh first time in hours and wifi activates, all of a sudden everything syncs and it's so damn laggy those first few minutes of use. it sucks. only this tablet. never had this issue with my nexus 7. that thing gave me 7 days stand-by time.

Try putting your tablet in airplane more overnight and see how much power it consumes. I lose 3% over 8 hours when I put it on airplane mode and disable wifi.
Im sorry but this is BS.
Its clearly faulty. its going to samsung. i demand a refund.
How much power wifi uses depends on the distance to the router and how much interference it has to try and break though to get a good connection which means using more power, that is why wifi uses more battery power on some peoples tablets than others do.
John.
disregard.. just realized my screen shots were messed up. I'll post my standby time tomorrow.
Here is a very simple stock no root mini guide to getting 1-5% loss over an 8-10 hour period while sleeping or at least while the tablet is asleep.
1. Install greenify even if you are not rooted and even if you do that have the donor package there are many many apps that do not like to sleep, greenify will fix that for you.
2. Unless you are a Doctor, CEO, or someone whose very life hangs on getting the latest cute cat post while you are asleep try to adjust your sync times from under an hour to as high as you can. (If you are turning off wifi then it might still matter if the app wakes up your device just to see it can't sync)
3. Samsung has given you a very nice QHD screen. It is high resolution, Amoled, and other nice rhings but while you sleep you can not see it so turn the brightness down before you touch the power button to 5-15. If you wake up in a dark room and need to use your tablet that level of brightness is far kinder to your eyes and even kinder to your battery.
Just doing this generally kept my battery usage down to only 2-4% per night, of course then I rooted my tablet and installed TW detox 3.0 and now it is closer to 1-2% per night. Try any or all of these and I hope it works out.

Just doing this generally kept my battery usage down to only 2-4% per night, of course then I rooted my tablet and installed TW detox 3.0 and now it is closer to 1-2% per night. Try any or all of these and I hope it works out.

losing 48% per day... screen brightness wont help will it when screen is off all day
Screen brightness is for those times that an app wakes up the tablet and turns on the screen to tell you something (new email, facebook wall post, new cat video, ect....) and yes it helps.
If you are losing 48% a day then you have some app doing something that is keeping your tablet awake for a good portion of the day. Or you have a defective battery/tablet. I can surf the web for a good portion of the day and maybe lose 48%.

Are you rooted. It's sounds like you have some wakelocks? If rooted you should use greenify and a wakelock alarm to fix the problem.
i'm curious to see what apps and how many you have installed. Can you post screen shots of your app drawer?

Ways to improve battery life?

Sorry for the long list of screenshots above, and also for creating a new topic, but didn't want to spam the normal board for battery discussion.
Anyway, I have the N920I model of the Note 5, using it on Telkomsel in Indonesia, and getting average 3+ hours SOT on this device, which I think could stand to be much better, given I got around the same figure on the Moto X 2014, which has significantly worse battery life according to most counts.
Here's my settings:
Screen brightness 60%, auto
Sync on
NFC off
Location high accuracy
Bluetooth on from 8 to 3.30, then off for the rest of the day
Connected to an Asus ZenWatch 2
Wi-Fi on from 4 to night, from plug out in morning to 8
Here's the list of apps I disabled:
And here's how my usage goes:
* Plug in when I wake up, then out at 7-ish.
* Get to school and let My Places switch to "Work" mode, where it changes the Bluetooth, Wi-Fi and power saving settings and turn off data before starting the first class.
* Turn it on between classes to check for new messages.
* Leave at 3-ish, and get home, letting My Places change the settings back to normal. At this point, the phone is usually at 70% with an hour of screen on time to report.
* Use it periodically throughout the rest of the day, switching between WhatsApp, Snapchat, Netflix, Chrome and YouTube.
* Plug in at 8 or 9, then plug out before I go to bed, topping up what's left in the morning.
It's a fairly light usage pattern, which reinforces the point that this phone should get more than just 3 hours. Any specific app you're seeing here that might be putting its toll on battery life, or a specific setting that you can advise enabling or disabling?

Just try counting how many threads there are about battery life in this section. A lot! I, being one of the victims of horrendous drains, have tried everything. If you keep the device relatively clean(software) and it still drains then there is only one thing you can do. Wait for the marshmallow. I'm sorry but that's what it means owning a samsung device.
try gsam battery monitor. It may give insight into what is going on....

Already did! But Android OS is always the top consumer.
thanks!
As Octa_core mentioned, there are quite a few threads about battery life already. They might be of benefit if you haven't already looked through them.
Here are a few things you might try, if you haven't already.
- Turn off location high accuracy, or only turn on location when you need it (if you can)
- Turn off location history
- Turn off Always Allow Scanning in Wifi advanced settings
- Turn off S-Pen settings (alerts, sound, vibration, detection)
- If using Google Fit, disable activity detection in settings (this definitely helped my idle drain)
- Turn off anything you don't need to sync on your Google Account
- Disable enhanced LTE services
- Turn off Motions and Gestures you don't use
- Set touch key light duration to Always Off (under Display)
- Turn off Smart Stay
- Set Screen Mode to Basic
- Use a darker theme
- Try disabling some apps, especially S-Finder (may require Package Disable Pro to disable some apps)
- What does your signal look like in GSam? Some drain may be due to poor signal.
If none of that helps, then uninstall or disable (probably will need Package Disable Pro to disable) all apps you installed, and I also recommend that you disable S-Finder. Turn off all radios (location, NFC, bluetooth, wifi, even data) other than cell. Reboot after those changes. Monitor and see how idle battery drain is. After I did this, my idle drain was around 0.4% per hour. Then you can gradually enable radios/apps, only 2-3 at a time, reboot, and see how it impacts idle drain. Continue until you find app/radio that increase idle drain.
