How do I get better battery life than my iPad? - Galaxy Tab General

My iPad gets better battery life than my Tab so what are tips to improve my Tab in terms of its battery?
Sent from my SGH-T849 using XDA App

I know some of these observations are pretty common across all devices but still here goes on how I squeeze more battery efficiency -
1. Change screen brightness from auto to manual and set it 15% (for me that's fine someone else may differ)
2. Turn off wifi when not needed as both 3g/edge + wifi drains battery faster...else rest of the time on edge/3g...
3. Reboot after using the default gallery app as it stays in memory and consumes battery even after closing...there's a bug which can be fixed from here xda...

One of the major reasons the iPad had a bettery battery life than the Tab is simply that the battery in the iPad has a 50% higher capacity.

get a battery twice the size & capacity
don't use 3G/Edge/HSDPA
Use a less advanced OS and apps that don't run in the background

Wait what ? I charge my phone almost twice a week !

Personally there are few things that you can do:
Here is mine.
1. Always use your back button when you close your apps instead home.
Using home will not close of the tasks that are running. Use the Active Apps that come with SGT. it's useful. if after you do a back button but still got application running, you should probably uninstall it and feedback to developer to re-look into the function. Don't use something like 3G-watchdog, Monitoring apps that constantly running, My personal reason is it's constantly running at the background so probably it will take CPU thus consuming battery.
2. Turn off your Wi-Fi, 3G, blue tooth and GPS whenever you don't use them.
A better way is to install tasker.
On display off: turn off 3G
On Display on: turn on 3G
Of course, if you are running messenger etc, you should turn off tasker: Common sense.
3. Switch the brightness to Auto or best of all switch to certain percentage that you think it's good enough for you.
Hope this helps.

An easy way is running a third party app like Juice defender. I gain an extra 30-40% on my battery life. Does much of the same thinks mentioned in the other posts but automatically executes them at user defined instances to turn on and off certain functions to maximize battery life.

I found I got a significant battery boost by installing tasker and setting up a few profiles.
First one is GPS turned off automatically unless Navigator, Maps, Layar or Google Earth are running.
Second is the phone radio is disabled if I'm connected to my wireless network at home, and once I disconnect from the network or turn off wifi, the radio turns on.
saved me quite a bit of battery today

Thanks for your tips. I underclocked my tab to 400mhz using set cpu and it works better on battery life. I will try the other tips.

I downloaded the tasker app and after an hour trying i honestly have no idea how to make it work.
The only thing that I want is that the 3g turns off when the screen turns off and that it goes on when I wake the screen.
If anyone could be so kind as to tell me how to do it.
Thanks in advance

I have been using Green Power App (Free in Market)
Here is the article that I followed:
http://www.gamaze.com/blog/2010/11/improve-the-battery-life-of-galaxy-tab/#more-249
To be honest, I get a lot of random crashes with SetCPU so I uninstalled it.
Before you use SetCPU you would need to root the Tab first. Here is the link to RyanZA's z4root in case you want to give SetCPU a shoot.

What am I doing wrong here?

Ok I got the X10 a few days ago.. loving it.. now..
How do I extend the life of the battery? I know theres a ton of topics on this but I can't seem to get more than 12hours..
- I use StartupAuditor and pretty much stopped most apps from running at start.
- I use ADW Launcher
- I use JuiceDefender
- Timeout - Screen timeout after 15s, lock after 2mins
- Schedule - Enable APN/Wifi for 1m every 15secs (for Moxie Sync/Mail - Push)
- Screen - Leave APN/Wifi enabled while screen unlocked (So it disables it after it has been locked)
Any help is appreciated.
After a couple of weeks your battery life should get better with out you having to do anything. Just be patient and let it fully discharge before recharging. Also restart your phone after a full charge and after using wifi and gps.

Discharing a battery is bad isnt it?
Well your problem may lay here
"- Schedule - Enable APN/Wifi for 1m every 15secs (for Moxie Sync/Mail - Push)"
Your using Moxier which other X10 users have identified as a huge power user and according to you, your also using APN/Wifi for a minute every 15 seconds..........so it's essentially never turning the APN/Wifi off :-S
Hope this helps!
Also fully discharging your battery every now and then is actually beneficial for your battery.
Quite certain the 1 minute every 15 seconds is a typo
Juicedefender defaults to 1 minute ever 15 minutes.
I removed ATK and Juicedefender, I found they only screwed up things in the phone and after removing them I noticed no change in battery life. (If anything, my battery life increased after removing ATK)
The best things for battery I have found to be.
-- Alternate launcher (I use ADW, I think Helix is better for battery performance but ADW has more options).
-- First 5 charges, discharge battery completely and do this again once every month or so
-- After full charge, power cycle phone (Turn off/on)
-- Use quick settings to turn off GPS, WiFi and Bluetooth when you are not using them
-- Make sure you back out of programs when you're done with them. This will close most applications so they are not running in the background. Certain apps (like a dolphin browser) have exit functions under more options. This is useful as back will just go to the previous page.
Note: Force closing applications which you see open in the background may use more battery as it may just start up again. Constantly killing and opening the program will use processor/battery power. Whereas many programs, when open in the background, are not using active process power and Android OS will pause/stop applications which are not in active use, by default.

Where can i find the timout setting for the lock?
Screen brightness turned down. Wifi instead of 3g. That's what I do. And I think I get around 15 hours. Still kinda bad. But better than nothing.

From my experience..
I find 3G has better battery life than WiFi, unless you are constantly browsing. When 3G is active, but you're not browsing the web and stuff, I find it doesn't use much battery. WiFi, however, uses up loads of battery when the phone is idle.

Battery barely gets drained by wifi in idle state. you just go into wireless settings and set wifi sleep policy to when screen turns off.. should be fine after!!

As per my last question, discharging is bad isn't it? With these batteries, you have to constantly charge them so they don't loose life
Edit: Also.. if I press home button or back button that doesn't close the app.. most apps don't close like that, so I have to use ATK to kill it.. is it fine to leave apps running in the bg like that?
Edit: So I should uninstall ATK?
I also JUST got an X10 about 2 weeks ago! My battery life was so bad at first, and I ended up trying most of these battery saving apps. But to be honest, I found that they did more damage than good.
I now have everything I don't use turned off. Bluetooth, WiFi (when I'm not home at least) etc. Just skim through settings and turn off anything you don't think you'll use. And I restart my phone every morning and I get 30-50 hours out of it, depending on use. It is definitely getting better with time too.
For ATK, I would uninstall it as generally killing tasks does more harm than good. If you use it intermittently and only when necessary (and not use auto-killer) you could keep it installed.
As for apps running in the background..
-- If you press back, it should close most apps (not all, but well designed apps should)
--The Android OS is designed to pause/stop apps/processes which are not being actively used by the user and will close them eventually if left unused
-- ATK is generally only freeing RAM which is not important. It is not like Windows in the sense that more free RAM = faster speeds. It is a lot more like, more free ram = more wasted ram.
Here is a link to where I found out most of this information.
http:/geekfor.me/faq/you-shouldnt-be-using-a-task-killer-with-android/
As for WiFi sleep policy, thanks for pointing this out. It seems that my phone is already set to sleep WiFi when the screen is turned off. I find this weird as I have found significantly reduced battery life when I turn WiFi on, even when my phone is mostly unused/idle.

Thank you so much Mobzter, but i was not after that As Sashi said that he has set "Timeout - Screen timeout after 15s, lock after 2mins", I know about about screen timeout but "Lock after 2 min", How? Thnak You anyway ^^
@mano. Good question. I can only find screen time out as well.

i have noticed some thing strange ,the phone lasts more with apps open in backgroung than when i close them . and using my phone consumes less battery than leaving it in standby .very strange phone (may be only mine ) any confirmation.
Hey Hoss,
I can confirm that force-closing/killing apps seems to be worse for battery life than leaving them alone. Backing out of apps usually will stop any cpu usage, but leave the app running. Killing/closing them will just result in more cpu power to run it when necessary.
As for standby vs usage - I have the opposite experience. The battery life on my x10 lasts a lot longer when I am working all day and not using my phone very much.

Battery drain even during standby with WIFI or 3G on

I have encountered a problem (or not!) that the battery seems to drain real fast (8-10% per hour) when the phone is in standby mode with WIFI on and the only app running in the background is Ebuddy. I don't know if this is a problem or not because on my old Blackberry Bold, even if you let a chatting app such as Jivetalk running in the background with WIFI or 3G on, the batterry doesn't drain that much, in fact it uses just a bit more battery than just standby. My phone is not rooted, and if I continuously use the phone for chatting, surfing and listening for the music, the battery seems to be find though, I get around 6 hours until the battery is dead. Any help would be awesome, thank you very much for your help
Try switching off your GPS. I did and now my battery is sweet. I only switch on the GPS when I need it, i.e. maps, weather, you get the message...
What widgets do you have on your home screen? I've had problems before with some of the active widgets preventing the phone from sleeping.. I generally get 2-3 % per hour when in standby.
Now at 88% after 6 hours..
I have wifi on 3g on and gps on and bluetooth on.. So they're all sleeping just fine.

Actually i dont have many widgets running in the background, I only use 3 home screens, the widgets I have are Beautiful Widgets, Calendar, Battery Life and I have Juice Defender running in the background full time. The problem is, standby mode without either WIFI and 3G is OK but with any of them, the battery starts draining real quick
you should be able to set wifi to sleep when phone display is inactive. 3g will always use more juice than 2g but how much more seems to depend on your location and 3g availability/strength. I get about 1 day use with 3g turned on and 2 and a half days with only 2g enabled.
It would be really nice if the phone could switch back to 2g when sleeping but its not possible to do because you cant control the 2g/3g directly from apps. The best that apps can do is display the standard android settings page.
Ahah... Juice defender... I've had problems with that preventing my phone from sleeping.. Suggest you do what I did and de install it.. My phone lasts a lot longer without it..
Also, if that still doesn't work try removing beautiful widgets, I've not heard of problems with that one but some of the weather widgets also prevent the phone from sleeping.

Thank you very much guys, I will try to uninstall Juice Defender to see how it goes. I did mention 1 thing in case you forget, I had Ebuddy running in the background, facebook and twitter update every 1 hour or so, but even that.the battery still seems to drain too fast, even when nothing using connect to the internet

Hi - Couple of things.. .. 1. Did you disable JD before you uninstalled it - read somewhere that this is the best way.. and 2. Have you restarted the phone to clear JD from Memory?
Which version of the firmare are you on? The older ones 014 and 016 weren't as good at sleeping..
Task Killers also tend to cause problems (@GT Blackice) They will stop things that need to be in memory and so the phone will restart them.. I've found it better without.. Phone runs smoother and battery lasts longer. (Although one or two others believe that they help; I think that this is because they're killing dodgy apps which aren't sleeping properly when not active.)..
Yes i disabled JD before uninstall it and did a clean reset even with taking out the battery. I'm on firmware 023, I think its the latest one for my phone. It's so bad if the battery cannot last any longer with WIFI on, anyways thank you a lot though

Disable APN(3g and 2g, there is a widget for this) while you're not using it and battery last significantly longer. If you need internet for E-mail push or some other apps(timescape) then use 2g(as was reccomended above) and be happy if it lasts for 2 days. I've also discovered that using wifi instead of APN uses less power.
That's really odd. I'm on 023 too and mine is fine.. The only other thing I can think of.. Possibly... I've stopped using timescape...
Other things about my phone.
Uk based.
Vodafone contract
NOT branded.
Not rooted.
Using ADW.
Using k-9 for email.
Handscent for sms.
No task killer, no start up manager.
No internet active widgets on my home screen.
Phones been on now for 16 hours.. Now at 60% battery left. Just also noticed that Gps has been off today.
Been at home for most of the day so not been using 3g/ gprs much.

How can u disable Moxier Mail if you dont use startuqap manager. Cuz this app was the real drainer. And how do you disable Timescape? Did you use any WIFI at all during the last 16 hours? I even uninstalled the weather widget and the prob stayed there, nothing changed. Arghhhhh...
Sent from my X10i using XDA App
I thought moxier was a problem too, but in the end turns out not to be.. As long as you've not configured it, it just sits in the background not doing anything. Haven't disabled timescape.. Just removed the widget and set the update frequency to never, then stopped using it.
Wifi has been on and active quite a lot. Used xda and internet a fair bit on it yesterday.

Did you try the wifi sleep method as mentioned earlier by someone? Perhaps need a new launcher such as adw launcher? I mean when I use my wifi I lose bout 12% or so per hr, annoys me, tried everything I could think of!
Sent from my X10i using XDA App
If you have a rogue app that is causing the phone to not sleep properly would it not show up under the battery status in settings?
If you see Cell standby, Phone Idle and Display at the top of your list in the battery usage and that accounts for around 90% or more then your phone is probably working as expected. If the display percentage is too high you can probably reduce the display brightness to save battery other than that the only thing you can do to affect the battery life is to turn reduce refresh times for apps which update automatically, turn off APN or switch back to 2g.
Thanks everyone for your advices. Anyways, the prob doesnt seem to fixed though, maybe its because of my phone.
@im_iceman: I did not configure Moxier mail but its still running in the background and drain a lot of my battery, the I tried Startup Auditor and it fixed that prob well, i dunno why

Hi.. How do you know that moxier was draining the battery?
I also stopped using start up managers too cos they were also draining battery..

there is always a chance your battery is damaged. Get a battery graphing application and see how it drains over time. One of my friends had a phone with a bad battery - one of the cells was clearly damaged and unable to retain charge properly and it was easily visible when watching the battery drain over time

Hi all! I've had my note for about a month with no problems, but last night it went flat in 11 hours of no use.... The battery use screen shows that it was the OS with nothing else running!
I have this problem too, really need to know answers!
Do u leave ur wifi,packet data, gps and Bluetooth always on? This may be the problem,just use any battery saver tools and close unnecessary hardware

Installed anything just before the drain problem?
Pretty much all the problems I've had with battery drain have been traced to an app misbehaving. The battery stats info can be a bit misleading too - so don't trust that the OS itself is draining the juice... Its more likely to be some service app that doesn't show up a itself on the stats.
I've found Widget Locker a painful battery hog, for example, but it never shows up in my battery stats. Instead the Android OS, or whatever last write to the system log (log cat) show up as using all the power. Uninstalling WL always fixes the problem so I know its that app causing the drain.
Also, is that shield in your notifications bar some sort of battery saver?
If so it may be the cause not the saviour! I've read that the latest free version of Green Power tries to connect to ad-servers constantly and drains the battery double-quick. Apparently the premium version doesn't have this issue but you have to pay for it, obviously!
the issue is undoubtedly running services..you probably added an app or three that is high maintenance.
shut down and restart your phone and then without starting or using any apps, leave it overnight to get a better benchmark for battery life.
If still low, look at the running services, you may be staggered to see what amount of crap is running in the background..

Mine hasn't had any new apps installed and normally loses about 7 percent overnight. The shield in the pic is lookout which I've always used without a problem.

some tips for better battery life.

[Q] How to optimize battery life od Note 3 ?

Hi !
I'am interested in optimizing battery usage/life on my Note 3.
I want to know what functions is free to switch off or reconfigure to decrese battery usage
But I dont want to cut phone functonality too much...
I'am not interested to tips like:
- switch Wi-Fi OFF
- switch Bluetooth OFF
- switch GPS OFF
- disable synchronization
- disable background data
- disable S Beam, NFC, Air Gesture, Air View, Smart Stay
- disable vibrations
- switch phone OFF when not using
- turn Power Save mode ON
- turn Airplane Mode ON
- lower down CPU/GPU frequency
Because they make phone much less usable and fun because it's many nice and amazing functions wont work...
I've already applied following tips:
- disable Google Now
- disable raporting GPS position
- disable location history
- turn screen brightness to AUTO
- remove unused/unneccecary widgets (especially this with auto update/sync)
- turn off autostart of unnececary apps (with All-In-One Toolbox)
- turn off "notifications from server" in "Samsung Apps" settings
Because i know that following tips are working and have positive impact on battery life (about 20% more power in my case)
I can't root phone (MJ7 firmware...) so I cant use Greenify to make more battery life...
If somone know some more configs/tips/apps that can be applied to increase battery life I will be very interested
- turn screen brightness to AUTO
Click to expand...
Click to collapse
This I believe is a myth, if anything AUTO uses more battery IMO. I set my brightness at around 40% or so and I get 30 hours (with 3-4Hours screen time) or so average out of my battery, Only other thing I disable is GPS.
It's more about how/what you actually use on your phone rather than what you can disable and not use.
I think you're looking for a reduction in "idle" battery drain as in use battery drain is kinda unavoidable.
There are tools like "Tasker" you can use to automate all the radios
you can use "app ops" to stop all the apps that push your location (this will do the most)
"autostart manager" allows you to stop apps from running all the time.
Do you have an n9005? If so the Snapdragon Battery Guru app definitely helps by switching your networks on and off based on usage, etc.

Yes I am. It doesn't make a night and day difference but it definitely makes a difference. I even uninstalled it to double check that I wasn't imagining it, now I'm annoyed with myself because it's still learning again.

Without all you wrote.. rules are those:
1) NEVER close apps (if you close the app ram pages will be deleted, so, it's needed to re-upload those, it has an huge energy consuption
2) use the phone "slowly".. i'm meaning, the fingers moves
3) if you are reading a text, read all the page than slide to see the new text, it's to prevent an high ramp up of frequency for long time
radicalisto -> thx for tip
nakedtime -> App Ops is quite good app ! Thx But "AutoStart Manager" is not working on my phone (crashing)...
dr.m0x -> I need to test this app thx
It's npt a good way to install an app to controll emergy consuption..
App needs cpu usage.. cpu ramp up..
so, you disable the radios for little time, and energy spent to do it could me more by cpu ramp up frequency
i suppouse you have the snap version.. and.. as i can see, snap has a good ondemand sysfs setting, it means it doesen't grow up frequency too fast, so, more than this is quite impossible
Only with an huge undervolt
I've installed this "Snapdragon Battery Guru"... now it's in "learning mode" I will see if it will help or not...
I have better replacement for "AutoStart Manager" and it's called "All-In-One Toolbox" which have the option to chose apps for autostart (and has many more other features) - i'am using it for quite a while and it's working fine

Yup just cause it's in learning mode, it'll settle once it's learnt everything

I will wait until "learning mode" ends and see if it's working
I am not a heavy user so a battery last more than a day sometimes 3 days.If I was I would just get an extra battery and not obsess over trying to maximise battery life.One of the advantages the Note has over most other phones is a removable battery.Take advantage of this feature.It takes less than minute to change a battery.
Replacing battery requires switch off the phone and taking off back cover of the phone (i'am affraid that it will damage it after many opens... i'ts a plastic after all...) and then put back cover and switch on the phone... It's troublesome and not comfortable...

It doesn't take long to switch the phone off.Mine takes 10 seconds.Taking the back off and replacing the battery takes another 15 seconds.Turning it back on takes another 15 seconds.All up less than a minute.
I can imagine how some people might be reluctant to take the back cover off almost daily.The back cover feels a bit flimsy and it's reasonable to assume it won't be durable with that sort of usage.I have the Note 1 and after two years of almost daily taking the back cover off it is still fine.The Note 1's battery life is horrible and even with light use I don't get a full day from it.Most people replace their phone after 2 or 3 years anyway so I don't think durability is a problem unless maybe you plan to keep it for 5 years.
But I can understand why some people might be reluctant to repeatedly tear the back cover off their brand new pride and joy.
I guessed everyone had their own way of energy conservation. For me, I use dark wallpaper. For our screen (Super Amoled), Black = LED off. LED off = not using energy. So in theory, black wallpaper or black background should uses much less energy than bright sunny light wallpaper.

This is very true for Amoled displays.The only time I notice my N3 drains the battery more than usual is when the display shows a lot of white such as internet surfing and using WhatsApp.Watching a movie does not display a lot of white and the N3 battery life becomes remarkable.
Battery
Go into the application settings and deactivate all samsung apps u dont need! Saves alot of Battery. Don't charge ur note if its Not empty. Just charge it if u are under 25%. You can also work with Tasker - it helps you to save your Power if u change yours settings automaticly. Also dont change ur brightness all the time
Hope it helps

Greenify?

If i can Root my 9005 - i intend to use Greenify,, as my battery is very poor (stock i'm lucky if i get 8-9 hours light/moderate use)
Is it a rated app,, can i expect big battery gains?
Thanks.
Depends which apps you have installed and how you use them. For example facebook drains much battery so you coukd greenify the app but if you do so you wont recive notifications anymore from it aslong you arent actively using the app.
In other words it prevents apps from wacking up.
As someone who already always manually force-closed all running apps, all I noticed was an increase in free time, as greenify is faster at it.
I didnt notice any increase in battery life.
If you don't manually force-close your apps, it'll probably have a bigger impact.

You will have some slight increases of battery of you force close the apps wich cause many wake locks like what's app

It seems to help mine. I run it with the Xposed Module that adds features that still preserve the notifications from Facebook, etc. I also have it set to boost mode for it to work faster.
I also haven't noticed much of an improvement. Many people swear it's a miracle app, for me it only turns off notifications.
True battery saver: green power payed version (on Google play). Set the phone to sync once at 4h and turn off wifi and mobile data on screen off. Awesome app, I tell you.

I do all that myself manually.... Sync always off and I turn Wifi or mobile data on when I need it, and turn it off when I'm done.
Cheaper than buying an app, too.
The real saver for me has been LUX. With our climate and the time I spend indoors, a brightness between -20% and 4% is more than sufficient. Now THAT saves battery! With brightness at 4, I loose 1% per 15 minutes whilst browsing! With it at 50, 1% per 5 minutes. At 100%, 1% per 90 seconds.
And when i use it in the dark, - 70%. I barely lose any charge at all whilst being an insomniac. It's been 20 minutes, still on 55% charge, which it also was 20 minutes ago. WiFi on, eWeatherHD update on, Tapatalk, Facebook and Firefox in use.
(if websites used less of that eyesore white, it'd save even more.)

I would suggest to remove some bloatware comes with the ROM / firmware itself.
It safes much battery though.
As well as turn on location, and on it when you want to use it.
And I freeze some apps which is running in background (which greenify can't detect it), which I don't use it as well.
and change to a good kernel.
it will really have a good deep sleep, never up if I never wake it up.
the apps running in background is only messenger apps like whatsapp, viber, and that kind of stuff. I never freeze this one and never put it on greenify as well.
So far so good.

I might look into that app. I go with the "free" lol DIY manual turn data/wifi off thing too, but sometimes I forget and I see wifi on when I had turned it off or so I thought. some apps are worth the couple dollars or so and I might very well get this one. Thanks for the tip on it. I like too that it automatically turns on wifi or data such as when you go to read an email or something.
You can also give these a try:
- Deep Sleep Battery Saver
- Juice Defender
- Tasker (You can configure it to auomate nearly anything, from 'turn on wifi at this and this gps location' to 'shut up completely between 2200 and 0800'. Does a lot of non-battery related things too, like launch a specific app when plugging in headset, or automatically move photo's from internal to SD.)

Juice defender is a dead project and 2 years old. Greenpower is basically the same app but still supported.

Hey thanks! I did go ahead with Green Power yesterday and I have to say I notice enough of a difference for sure. My usage has been with a phone call, check messages, several texts, check email a few times and some light surfing. i'm at 89% at 8 hours pulled off 100% charge and would have been lower for sure into 70s at best. definitely notice.
