How to significantly increase note 2's battery life? - General Questions and Answers

Can anyone suggest me how to increase my note 2's battery life?
Currently it works for 32 hours per charging and earlier before rooting it used to work for more than 42 hours.
Android's description:
Note2 (N-17100, XXUEMK4 , rooted 4.3 stock firmware.)
Please let me know how to get around 50 hours of battery life per charge.:what:

I dont know about 50 hrs but you can significantly increase battery life by making sure you dont have background tasks running while its in standby. Ergo a task manager or auto task killer. But be careful if its rooted and you use a root app task killer it can kill tasks that you NEED running. Also if you can find an app that will trickle charge it when its at 100% battery and your not using it that will prolong your usage as well. Not sure what else you could do besides that or see if you can find a way to undervolt it with a power managing app *for rooted devices*

Hello, there are many ways to "slightly" improve battery usage but you can't significantly improve it. If you want to get 50+ hours, try a app called Easy Battery Saver. It generally gives me another few hours of battery usage.

[Q]Best Rom for Battery Life?

Which one would have the best battery life? Or if it's a multi-step process (pick a certain rom then change kernals or something) could you link me/tell me also ?
I'm using Octane v2, and it worked good for the first day, but now it's draining my battery so quickly, even after the battery calibration. I'll lose 2% battery while watching a video for a minute or two.
airfluip1's KJ6 AOSP Style
I haven't done much testing but for the last few days I've been using airfluip1's KJ6 AOSP Style and the phone's battery just died after being off the charger since late Sunday. That's almost two days of juice on one charge.
I also have had excellent battery life with the MIUI ROM variants around the forum, but they are still works in progress and aren't feature-complete yet.

I don't think battery life will differ much between the roms we currently have available, as they all have a stock kernel.
Though under-clocking and juice defender work well for me, I am a heavy user, I've not been able to get more then 14 hours of use.

to undervolt, pay for tegrak ultimate from the market. then input dsexton's undervolt values from icbinb threads.
I found a way to not pay and u/v but thank you !

Battery life question...

Well sortve. What do you guys consider good or bad battery life on this phone. Right now I'm running Sky ICE with faux kernal and getting about 10% per hour. To me that's better than what I got stock considering its OC but how does that compare to everyone else's?

I am really heavy user and get about 10hrs or more with 2h52m of display time plus 44m of Asphalt 6 hd gaming. So it all depends on how you use your phone.

I'm running Space Pirate with romracers kernel (no OC) and my battery has been improving daily. Started around a drain of 3.7-4.0% per hour and the past few days has been 2.4-2.7% per hour. This is all with moderate use throughout the workday. Responding to a few texts here and there, checking some email, surfing the web while at lunch, and browsing the XDA app while in my other office (the bathroom... which may or may not be right now). Last night I plugged it in at 4% remaining after 1d 11h. So I've been very pleased with its battery. Compared to my Captivate, anyway, which couldn't even make it through the same workday.

I get about 14 hours or so with Sky ICS but I still feel like it could be better

Best battery life ROM?

Which ROM do y'all think gives the best battery life? I'm on baked right now and right as I get out of school I'm down to 35% usually, thanks

I use viper and it is giving me a good battery life. I don't know about aokp/cm. I think you should try everything and then you will chose whatever is good for your needs.

How is the stock Rom with battery? Just wondering if it's worth rooting and putting a custom Rom on for battery
Sent from my SGH-T999 using xda app-developers app
cm10 has nice battery life ..m using dark jelly S v20 the battery is really good works almost a day for me with me almost connected for 14-16hrs of wifi connectivity and listening music and of course auto sync always on ! u should try all once before proceeding further
Energy ROM and of course.. other stock based ROMs have the best power management available, you know, engineered by HTC

For me, cm10 gives better battery life than stock Sense. I think it depends on how you use your phone.
I'm using Baked too, but for me battery life is just great! Actually on 57% with 8h 27m and almost 1.5h screen...

Of course rooting for battery is a good idea. Undervolted & underclocked kernels, delete bloatware that's constantly running, etc. And as far as best battery life, baked has been very kind to my phone.
A typical day for me (7am on phone for 2-3 hours reading the news before work, music to/from work, light usage on breaks, then hotspot at home for internet, and all the calls/texts in between and countless downloads) will leave me with 20-30% battery when I go to bed around midnight

snapdragon batteryguru app

Has anyone used this app on the htc sensation? I have installed it and so far it is "learning".
https://play.google.com/store/apps/details?id=com.xiam.snapdragon.app
just installed it and will test it until I flash Elegancia update.
Hopefully the Qualcomm guys did a good job
AW: snapdragon batteryguru app
Mine is also learning.
Does anyone know how long the app "learn" and is it possible to restart the phone to flash something while it is learning?

After a brief 2-4 day introduction period, Snapdragon BatteryGuru learns the user’s behaviors and then notifies the user that it is ready to extend the battery life and improve the experience. (that's what the developer says in app description)
When you flashed your device you have to start from scratch teaching the tool your behaviour.

I mean, if a flash a mod for example and restart the phone, is battery guru learning again from beginning?
No clue, but I don't think so if you don't change something deep in system with the mod
I've used it for a week(after learning process which took 3 days initially ) and honestly i didn't see any improvement in battery at all ..I always use auto sync but still ..
give this greenify app a shot ..its performing awesomely good with regards to ram and battery ( i got +5 hrs total time during first cycle )
Yes, heard of greenify. How long are you using it yet?

I'm using the snapdragon app for 3 days now. Battery life is about 10 – 20% better. Draining much slower.
Before that i was using battery juicer. That always told me factor 1.8 with Anker battery.

[Q] RAM Usage and Battery Life on Kitkat ROMs

How is the Nexus S performing as regards RAM usage and battery life on the handful of unofficial Kitkat ROMs doing the rounds? Kitkat is built to perform better on devices with 512MB RAM than Jellybean. Wondering if that translates into actual differences in performance and battery life, even on the as-yet-unstable ROMs.

Battery life is pretty close to most jelly beans, it has better ram availability, but is smooth like 4.1 only a bit faster... Some apps still have issues due to the newness of 4.4, but mainly in ART... Most roms are pretty stable for daily use...

Thanks. So in that case, I shouldn't expect more than the 1.5-2 hours of screen on time I've been getting using JB.

In that case, much better than what you were getting.. Lol... I get around 4hrs screen time with 12-16hrs moderate usage..

Wow, how do you get so much screen time?
Pixie dust... Lol. I don't have 3g on unless I'm using it, location off unless needed, I keep WiFi off when the phone sleeps, I don't auto sync, screen brightness is usually on lowest settings, I set app permissions to not wake my device, greenify, and use a script package with nodded build.prop...

I'll try that and see how long my battery lasts me. Although then I don't know what exactly I'll be doing with the phone at all. Usually I have 2G always on, switching to 3G when I need it, don't use WiFi. Auto-sync is mostly off, brightness lowest indoors, and a few apps greenified. That gives me 2 hours max of screen on time over moderate use for say 8-9 hours.
