In the interest of branching out of the main thread, I thought I'd start a thread regarding battery life- how many hours are you guys getting? For those who have somewhat decent battery life, what tweaks/settings are you using?
I went and disabled background data syncing hoping this would at least help improve battery life only to find that even idle (with no real use at all), this thing eats battery like there is no tomorrow.
I think with super light usage the most I've gotten is about 4-5 hours. There HAS to be a way to improve on this. I can never walk around without my charger in my bag- that is just crazy.
So any ideas or suggestions would be great! (By the way, I'm running Dexter's latest rom on top of eLocity's official firmware update).
I'm posting 4 hours 54 minute uptime right now with a quick 10 minute game of fruit slice, light to moderate web browsing, and moderate to heavy instant messaging. I have 29% battery left.
I generally set my apps to sync no more frequently than 30 minutes at the least. I turn the screen off when I walk away to do something. Other than that the tablet stays running on my couch side all day.
I have also seen it go for days on standby mode without going dead. I'm happy with the battery life. My Archos isn't much better, and is much less powerful of a device.
I'm also on ElociMod (which is based off the newest firmware... )
cant get more than 4 hours no matter what i do. running dexter's modc
We might be able to help the battery life using some clever tricks with SetCPU. I know it helped on my Pandigital Novel, and 2/3 on that device was used to power the screen, as opposed to ~1/3 for the processor. I'm gonna guess it might be the complete opposite of that on the A7.

I don't think SetCPU works on the A7 or any other Tegra2 at least not yet.

It doesn't... it will FC.
CPU Tuner installs and runs. It shows a min of 260 MHz and a max of 1000 MHz, and it has profiles based on battery charge. I just installed it, so I don't know what to expect.
I wanted to resurrect this thread and post my experience with A7 battery life.
I am running Dexter 1.2, brightness at 35%, WiFi always on, Bluetooth mostly off, screen timeout at 2 minutes. Syncing three mail accounts, weather and Google calendar. Limited or no background syncing of other apps.
My typical day with the device consists of;
a full charge in the morning
3 to 4 hours of standby time
30-45 minutes of web use
another 3 to 4 hours of standby
3 to 4 hours of heavy web, texting, reading, and games
I place the A7 back on the charger at night and it usually has about 20%-25% charge left.
I figure I am getting about 4-5 hours of use and close to 8 hours of standby each day fairly easily.
This battery life is very comparable to my Droid 2 Global.
The ipad battery has more than 4 times the capacity of the A7, but only twice the run time.
Hey guys im in the process of doing a little experiment to see actually how much Juice Defender with Ultimate Juice actually improves the battery life on my Evo4G. I'm sure this has been done somewhere else i just couldn't find it so i decided to do the experiment myself and post my findings this may be useful to some people or may not!
Phone: Evo 4G
ROM: Cyanogen Mod 6.1.2
Kernal: Zendroid BFS @ 1.52ghz w/ smartass scaling
Launcher: Go Launcher
-----------------------------------------------------------------------------
Phone running Juice Defender With Ultimate Juice
Phone Unplugged At 11:42am
Phone Died At 8:59pm
Usage: For the most part it was moderate use, no gaming, 2 calls lasting for a total of aproximatly 45 minutes. 120 texts were sent and received 146 within the time frame. There was no browser usage just mostly texting like i said. 3 Pictures were taken. No Wifi. Bluetooth or 4G used either.
-----------------------------------------------------------------------------
Phone running without Juice Defender With Ultimate Juice
Phone Unplugged At: 2:50pm
Phone Died At: Never
Usage: Well my phone has been unplugged since 2:50pm and its now 12:35am and my battery is sitting at 55%. Weird... very weird. I had about the same usage as yesterday i played 1 game for a total of probably 10minutes and installed 4 apps. A had wifi enabled for probably an hour total.
-----------------------------------------------------------------------------
Final Thought: I think Juice Defender doesnt help at all, infact it seems to hurt your battery more than anything. I think it may be because its constantly turning things off and back on consuming battery? Thats the only thing i can think of. Does anyone else have any thoughts on why this is? Using Juice Defender reduced my battery life dramatically it almost cut its life in half as a matter of fact. Please share your thoughts on why this is people!

thanks for the info. i try to tell people that juice defender doesn't help. but no one listens so i gave up and just tell them cool app and walk away lol.
very helpful post. I noticed too it doesnt seem to really help it just monitors mobile data and turns it off when screen is off and occasionally powers it on to download emails and ****. I dont like it because i like to kno when i get an email instantly versus it checking every 30 min.
I also found that juice defender seemed to have a negligible impact on my battery life while also decreasing speed of sync/convenience. You'll notice that it also makes android system skyrocket towards the top of the battery use list.
On a related note, I also found that setcpu profiles don't have an impact on battery life and may even hurt.
Ultimately, android is optimized to manage a lot of these things on its own and introducing an app that consumes battery both monitoring and brute forcing some of these activities doesn't make sense. The only active monitoring app I use now is Tasker for some specialized automation activities.
i cant believe this is an app that most people recommend to improve battery life tho. Especially with how much it hurts rather than helps. Very disappointing.
It has helped mine because I use the widget to manually shut it off and on. I don't let it control it. Since the epic doesn't have the shut off data in the power menu its good for me. Otherwise I agree with you all. I keep my data off until I need it to look something up. Personal preference. But hey it does shut my data off when I tell it to.

I had been using juice defender and setcpu for a while trying to get the best battery life, but I ditched them both about a month ago and I'm getting better life than ever before lol
I've got 58% left in the battery and the phone has been up for 32 hours. I thought I was helping by micromanaging the phone with JD but I think it was really just hurting it.

32 hours up and only down to 58%? Mind if I ask how you set thigns up that your phone is so energy efficient?
It was a great application, Donut times, it literally made my Magic 32a survive the day against the not-even-a-day battery life at those times. Nowadays it is simply useless due to android better app management.
Hmmm...I have been using this for a few months now and I've seen dramatic improvement in my battery life. I usually unplug my phone at 7 each morning and by noon on moderate usage days I'm at 60%. Using JuiceDefender, my phone is typically at 80%. By 5pm with its only at %60. Normally I would get home at 5 and it would be around 30%. Interesting.

With more iterations of Android they are improving power managment, Ya back a little bit ago this helped some people alittle it closing out processes and way to handle things but with android development alot of this stuff is getting worked into the OS, basically now all your doing is running a app constantley that does something handled by the OS now in newer builds.
I wonder in some cases if the juice defender and the OS both trying to do power management if it can actually cause more power loss due to a conflict in the two trying to controll items. Of course OS should have higher pid but could cause some of your increased power drain using both
try the beta
im using it on my epic and my evo i think it helps both but i am also using the free beta i dont think the regular one works
i'm shocked there's even a thread for this. i put it on a stock epic and it made a WORLD of difference.. especially in locations where my signal was poor and evdo service kept dropping. my issues with it are of a different nature. seems to get corrupt alot and the wifi locations service sucks
Hmm, i'm confused on how this could actually hurt battery life, especially by the amount you displayed unless you have it doing all kinds of other management as well. I have mine setup to only manage the data APN, disabling on screen off, and seem to have gained decent battery life from it. The widget to toggle data on/jd on/off is very handy as well.
Pretty sure android doesn't do anything natively that turns off data when phone is at rest/screen off, does it? Someone please correct me if i'm wrong.
I will admit, the new versions of JD do seem to be pretty bloated and sluggish.. i've been on the fence of whether to remove or not... The main reason i keep it on my device is because i work in a basement and get about 65% TWS and severe battery drain from that. With JD managing 3G, it helps mitigate that somewhat, and having it be automatic is much more convenient than toggling it manually all the time.
I may have to join you on some testing, because if JD is not gaining me anything, i'll definately be removing it as it sometimes causes some initial sluggishness when turning the screen on. From daily usage experiences (and i watch it like a hawk), my battery life has definately not been made worse.. older versions seemed to net me more life, and i'm undecided on the new versions. Not enough time with it on/off to decide yet.
Most Def Work
JD helps... it will slow down notifications and stuff, if you need always on data then this won't help. However, during the day I'm usually already online and don't need non-stop notifications and if you use JuicePlotter you can clearly see that while sitting idle with JuiceDefender on you use significantly less battery than if you don't have JuiceDefender active and have it sitting idle.
for those that think jd works...
are you using the free, pro, or ultimate version? looking to buy if it really saves battery life.
which configs did you use? I had it a few months ago and my battery did actually improve. Trying some different settings makes a huge improvement.
I am using superpower now. (from XDA actually) And this is really working, it also takes some configuration, but eventually it will benefit your battery life.
Superpower turns data to 2g when your screen is off, disables wifi and bluetooth and sets your cpu to a 400mhz cap (at least with my phone) I noticed a 1% overnight drain and a 200% increase in battery life. (basically I do two days with heavy use vs. one day before)
Hope this helps some people!
The only thing that actually changes the battery in an evo is a kernel. No quick fix app is going to help how your system interacts with your battery! Senseui is garbage and it sucks up battery life like no bodies business!
Could you guys tell me if various ROMs have different battery life? Just to know if it's worth trying other ROMs or whether it would be a waste of time. (I already use a good kernel for battery life, i.e. M-Kernel.)

I have never had better battery life than I do now on stock rooted 4.2.2
I'm at 41 hours now with 2 1/4 hours screen time and battery is at 66 percent.
I know that's not a lot of screen time so far....but excellent sleeping! Very happy with stock!

I'm currently using PA 3.1 and M-kernel a-37. I usually get between 35-40 hours (3-4 hours on screen time) with moderate usage (browsing, light gaming, occasional YouTube viewing) before needing to charge.
Currently as I'm typing this, my N7 is on 15%, been unplugged for 40 hours with on screen time of 3h12m.
I've managed to squeeze a week out of Paranoid Android 3.0 running Faux Kernel under clocked to around 800Ghz.
Just experiment like the rest of us.
Probably very little battery savings are attributable to the ROM, unless they've got apps pre-installed that hold lots of wakelock time and prevent the device from sleeping.
I throw mine on the charger as soon as I stop using it, so I don't really care what the battery life is. If I've used up 6 hours of screen time per day, that indicates a problem with the operator, not the device
Folks that have tilapia (3G/4G) N7s or live in a WiFi-everywhere (campus?) environment are probably more mobile with their devices than I, so no doubt their use-case scenario - and thus battery use concerns - are different. But I'm skeptical that ROM choice (independent of kernel choice) has much to do with it, unless a pre-installed app is pathological.
I agree with the above mostly, although underclocking does help a bit. I have 5hours of screen on time and 15 of sleep on 16% battery right now.
Hi there. After reading many threads on battery life and screen on time (which youre all probably sick of hearing about now), i have a question about peoples results. They always describe what they did with their phone, and what toggles were on etc, but they never mention the brightness.
I see people getting 6hrs+ of screen on time, is this with the brightness at 50%? 25%? 10%???
What is a normal SOT using FULL brightness. Thanks
I always have my phones on full brightness, There are always comments on here about turning stuff off like sync, google now etc and saying "whats the point of having a smartphone"
I put the screen in the same bracket.. I've seen people boasting about getting 6 hours screen on but when questioned they have their brightness on 10% or whatever. Whats the point?
The screen on both this and the gnex are lovely, and only can you appreciate it by getting out of that mard ar5e zone and cranking the brightness up.
3 hours screen on is enough for my use, i'm getting that now using franco's kernel (was only getting 2 when i bought it)
My screen is auto brightness and it's usually 50 percent brightness and hundred here and there and I get 5 + hours on the matrix kernel.
It's usually the stock kernel that has a low battery life

Underclocked and undervolted (no difference in performance) I can push 4 hours SOT 100% brightness, with heavy gaming, web browsing and calls.
Whoever gets 6+ is using auto brightness.

But it's not like the auto brightness is trying to intentionally save battery by lowering brightness to an uncomfortable level...

Note3 running Beans stock 4.2.2 rom. I've removed/disabled a lot of the system apps/bloatware and run a couple xposed mods (in pic below). Phone was half on wifi half on good 4G; also in good service areas entire time. GPS off, automatic brightness. I only get 4hrs of screen time and total running time is approx 8hrs with 15% left. I think this is quite low for a 3200mah battery. Anyone give me any suggestions to prolong the battery?..or reasons why I can't seem to go a full day?
...I posted this because my bro has stock nonrooted S5 with high brightness on whole day and can easily go 1.5 days with same on screen time so I was lil disappointed in my note.
Thanks ahead of time for any help!

you have something keeping the phone awake or chewing the battery...most note 3 get about 15-25 hours per charge... i keep my brightness fixed at about 25% i have greenify now it seemed to help.
How do I check what it is? I'm not sure what it could be but know that 15% with 8 hr total battery time and 4 hr screen time that it's a little under what I expect out of a note3.

solution to low battery life
It doesnt seem to be a problem since my old note 3 had the same battery life.
A tip ill give u is to try to turn off the wifi every while...
And also try to use this app: screen filter
It reduces battery life by lowering the brightness.

I have similar issues however I get a little better battery life as I have basically turned off every good option on this phone in order to make it last . Ive concluded that this phone has terrible battery life due to Android 4.3 and higher sucking up the battery unnecessarily .. the background processes are endless and truly destroy the daily longevity and options of this phone. Take a look at the Note 2, same battery, different operating system and more or less same hardware and out of the box the note 2 lasts WAY longer than the note 3 (at least from my own personal experience). Frankily, if it was possible, I would love to downgrade to 4.2 (or 4.1.x) to see how significant of a change the battery life would be. Thats my 2 cents

that just adds more evidence to my theory... the android 4.3 OS is a battery sucking operating system when it doesn't really need to be.
I never had a problem with 4.3. I was running hyperdrive 4.3 with greenify, v6 supercharger, and a crap storm of other tweaks and xposed mods and with very little usage (didn't take a screenshot of screen on time) I was at 5 days 13 hours 43 min with 6% battery left. I tried to update to hyperdrive kit kat and had nothing but problems so I flashed stock nc2, upgraded to nc4 modem and have spent the last week (couple hours a night) modifying and tweaking. I'm currently at 1 day 20 hours 13 min with 4 hrs 15 min screen on time and I have 19% battery left. I would probably be closer to 25%-30+% but last night I decided to go all out with the cpu control and run antutu benchmark twice to test different I/o schedulers.

So do you think with a custom ROM instead of being on stock 4.2.2 will help me get more outta the battery?

Probably the first step would get better battery stats and find out what is draining your battery. Freezing app apps won't do much to save battery if your not freezing the ones draining battery. Also look into greenify you can hibernate apps that you need installed and to run frequently but can put them to sleep when you don't need them
Also I got rid of V6 and decided to do min free and kernel tweaks manually with Rom toolbox pro. Not sure if a fluke but currently I've had 2 hours of screen on time and only dropped 20%. That's as much a 10 hours screen on time on a single charge.

Did you flash to stick slot and flash nc2 before flashing hyperdrive or were your issues some menus did not work if so those have been patched and everything works now.
I had wakelocks that lagged my phone (500k+ in twelve hours) and ran the batter almost dead in that time. Yea I flashed nc2 upgraded to rsl8 and updated the modems. Just didn't feel like trouble shooting anymore and with xposed I can have everything I want and biting I don't
