Surely not normal??

Running Liquid 1.3 Rom with Franco Kernel
48% Battery left
1h47min on battery
1h15min screen on time
Brightness is at approx 70%
No wallpaper and therefore black screen
Battery Status says "Good"
Surely this isn't normal?? I've tried various other roms and its the same.

I dunno but I just got this phone today, stock and rooted. My battery dropped from 100% to 90% in about 20 minutes. Not a good sign...

I thought my old HTC Desire HD was bad but this is in a different league. I'm on 39% now!

I get about 14 hours with moderate usage and about 3.5 hours of screen on time before the phone dies.
Try using CPUSpy & BetterBatteryStats app to see if the phone goes to deep sleep when screen is off.

Were u using wifi? If not and on a 4g connection the whole time then u should not be surprised by that battery percentage. 2 hours of screen on time with constant 4g is pretty typical.

I wouldn't really say that is good, my previous android phones got double that.

You just started using your phone, give the battery a day or two to get into it's "rhythm".

That looks about normal. You have a 4.65" display, pumping a lot of juice into it. Turn the brightness down to %50 or less.

[Q] Kernel with best batterylife for AOKP

Hi guys!
I'm running AOKP milestone 4. This rom is superb!
I'm only having troubels finding the right kernel with this rom for an ever lasting battery life.
I've tried Franco, Trinity ad GlaDos battery dies on all kernels at +/- 18 hours with 1,30 hours screen on.
On stockrom my battery survived 23 hours with 2+ hours screen on.
On the kernel treads I see guys with 24hours+ up to 50hours battery life with 4 hours screen on.
So what am I doing wrong? (I don't know anything about tweaking voltage etc)
What settings works best for you? Please share!

try betterbatterystats and chek for wakelock...maybe a rouge app keep your device in a non-idle state.

Yeah try BBS like the above post for any issues. Also people get crazy battery life because they could also be using Juice Defender, sync turned off, brightness turned down, etc. It ain't hard to get long battery life if you do all those things.

I've checked. Nothing special on wakelock
Seems to be 'screen on' causes the biggest drain..

Juice Defender - Should I keep using it?

So over in a Development thread I mentioned that I use Juice Defender Ultimate still, I got some heat for it because it's old.
What's new that I should be using instead? Running CM10 11/30 Nightly that I v6 Supercharged (Die-Hard, so I don't think Tasker will work).
I don't need anything to sync or notify me when it's in my pocket, just calls/texts via radio. I also already use CPU Sleeper and it's locked in memory via v6 bulletproof.
My goal is to make the most out of my battery.

not sure exactly. i used to use green power battery. these data killing apps used to work miracles on gb and froyo. but nowadays i think the main battery killers are the hefty processors. i now focus on kernels and governors and whatnot to save battery. i think killing data will help if it stays off most frequently. when you have the settings to turn on data as soon as the screen turns on, the device is toggling data and constantly searching for signal, maybe even killing more battery than saving.. idk thats just my opinion. and on the other hand.. if your not really using your phone so much i think it would save more in the long run. i would just test it yourself and see what works

Only thing that will improve the battery is a new phone .
I've tried everything. The best result has been ditching AOSP and going back to TW. It might not be fancy schmancy, but it functions and has marginally better battery life (at least in my experience).
Good luck on your quest. I'll probably keep my eye on this thread to see if there are any new suggestions (but not very optimistic).

I unistalled JD and set a CPU profile to reduce clock speed on lock, testing for wakelocks now as well.
Anyone know best governor/scheduler combo for battery on CM10 while still keeping it buttery? Im using OnDemand/Deadline for a few minutes and it has not dropped yet.

Sorry but no one can say for sure whats a rock solid combo. I suggest you try them all like I have to see what works best for you. After trying everything I came back to Ondemand and felt it gave me the best results but thats me.
Good app to try is Llama and its free and does all JD stuff and more

to add, regardless of what kernel i use sometimes the processor will climb to unnecessarily high frequencies when the screen is off. to tame it a little more use setcpu and enable profiles. my profile, when the screen is off, is min 384 max 540 and conservative/noop. then when the screen wakes, interactive/noop 384/1512. but im sure most of you already know this. cpu sleeper will do the trick too. beware of wake lag

I'm using the same Anket battery. I followed everyone's advice, ditched JD and made a SetCPU profile.
I think it was Google Music draining my battery so bad. It's absolutely amazing now.

I no longer use Juice Defender and, for me and my set up, JD did not have noticeable impact.
Nor did more complex strategies using Llama.
The ROMs, governors, CPU settings, and tweaks seem to be where it's at.

I have found that to be the case with every such app I've tried. The best results I've always had have come from removing apps that I don't need or use. I can get thru a full 8 hr shift, so I'm happy.

Battery Life Discussion

Ok so here are the tools I use
An automatic radio activation tool that will turn radios/wifi /gps OFF when screen is off - Juice Defender Ultimate is my choice
A CPU management tool - I use AnTuTu CPU Master but i hear that SetCPU is also very nice
Better Battery Stats
I Have setup Juice Defender (JD) to turn off my radios/wifi/bluetooth when the screen is off, to manage auto-synch, manage screen brightness but i DO NOT use it to manage CPU. I have also not setup any special App settings in JD, it just manages power consuming hardware (other than cpu)
My CPU tool (whichever you use) is used to setup profiles based on situations. Screen off, screen on, in call, etc.
There is never any reason for your CPU to be over 700mhz unless you are interacting with your phone. When you are on the phone 920 is all you will ever need. You can set the max above 1200 if you want or need the extra power but just remember that the cpu is always going to be a battery drain.
The #1 thing to remember is that if your not using your phone actively, it should be doing as close to nothing as possible.
Now I would love to hear from others on experiences and strategies or even critiques of my method. I know many will say that JD is not needed, bit i like not having to think about it.

I stick with Trickster Mod app for CPU/kernel settings. It's amazing. Also I never use Juice defender I use Tasker :thumbup:

Good idea starting this thread but I feel that you've opened up a can of worms
I've used JD before on my Dinc2 and I liked the fact that it can manage the radios but for me, I get a lot of emails and I like something on so I stopped using it. I did try some other apps like that but JD was my favorite by far!
Check out TricksterMOD from the app store it blows setcpu out of the water! It let's you do so much more and since I've found that I can't go back to anything else.
I usually don't undervolt, I feel like the kernel developers so a good job with their frequencies so I leave that alone lol but I have been recently checking out the governor settings to try and optimize a few things, that's a tricky topic lol

Um.. wow.. i wasted money on a few other apps apparently, trickstermod looks amazing..

Not sure if this is the forum for this but a good discussion none the less.
What ROM you guys running for best battery life? I seem to get the most from aosp based roms and not cm10 or aokp ones.

Im using XenonHD with Tinys kernel. I saw HORRIBLE battery life until i took action to tame it. now its much better

Mines close to stock on purpose but I don't mind people tuning it. What did you change that helped battery? There's bit much from a kernel perspective that will really help battery.
And this topic doesn't belong in development.
Sent from my Galaxy Nexus using Tapatalk 2

i guess it belongs in general but the idea was to get all the tidbits that we need together in one app specifically for our phones. like "The CDMA Galaxy nexus Super Battery saver app that does it all without all the stuff you dont need"

Just flash lean kernel and turn off mobile data when you're not using it. No need for these crazy battery saving apps. I get ~7 - 9 hours a day, easily.

Since radios are such a huge drain ...
I think my best move has been using an app called Profile. You can use it to turn off and on WIFI, Bluetooth and change the screen brightness at certain times on certain days. So at my usual time to go to work, WIFI gets shut off. At my usual time to get home, WIFI back on.
Also will change ringers, volumes and vibration on/off (always off uses battery).
24 hours no problem.
Costs a couple of bucks to get the time based control, but works for me.

Two tricks are using auto brightness and using WiFi whenever possible.
However, since I can't stand either of those options, using trickstermod to set max CPU speed while screen off, and setting color profile to morific typically helps my battery life.

CPU max is capped at 350 or 700 already there's no need to change it.

Yah why would you need to lower CPU on sleep when we have deep idle?

I use CM10 nightlies, and the latest dev snapshots of Imo's leankernel. Min frequency 230mhz, max 1350mhz, interactivex governor with his tweaks and sio i/o scheduler.
I get ~24 hours battery with decent screen-on time, from just texting, about 20 minutes on the phone, and websurfing on full wifi service wherever I go (stays connected even when sleeping, and we have cross-campus wifi here). 3g service only, no LTE here yet. Bluetooth off. NO apps--many of the market "powersaving" apps will just wake the phone from sleep and cycle a few times to write to the log file (any app that keeps track of power consumption, and half of them don't even use the system tools). GPS is on, but it's never initialized more than 1-2x a day for random needs.
Getting a lightweight kernel is a good choice for battery life saving, and getting one that actually keeps up with android mainline is pretty key.

I think it's most helpful to post your total 'screen on' time and time since charge. If someone tells me they get 14 hours, that means nothing. I can get a full day 16 hours with roughly 2 hours of screen on time, without limiting my phone via turning off mobile data, syncing, or using a juice defender app that disables a lot of things.
That, to me, is not very good at all. I saw that the Nexus 4 is getting about 4.5 hours of screen on time with a full day of being on with everything syncing, etc being on. 4.5 is actually pretty bad also compared to other devices these days.

No matter what I try I usually only get about 2.5 hours of screen on time. I under clock to a max of 750 screen off at 280 undervolted to in each setting.
I've tried many many kernels with many roms

Screen on time doesnt mean much me to me because i use my phone for personal and business use, which means I get quite a few calls.
I use the stock 4.1.1 image, rooted with SuperSu and debloated a bit. Also use Faux kernel 23m-sr and his control app.
I roughly get about 2.5 hours screen on time with light calls and about 1.5 with heavy calls - my off charger time is pretty good though as it easily gets me thru the day. I bought another OEM standard battery and just keep one fully charged at all times so I can swap. Works well for me.
I also keep 4g on - why not when you can swap batteries.

does leaving gps on all the time if you're not running any location apps bother the battery at all?

No only when you use something requiring device GPS does it turn on. Most background stuff like Google Now uses tower fix so it's OK to leave it on.

Battery life is a pretty unique experience for everyone. Apps, ROM, kernel, signal, Wi-Fi time, brightness, etc. Won't say these type of threads are totally pointless but they are pretty close to it. Always good to share pointers on how to save a few minutes of juice though. Ultimately its a big screen and turning it off now and then is the best way to save but personally I leave all my services on because that's why I bought this thing and I keep a charger everywhere I go.

[Q] The WORST battery life for 3800 mah battery

i have the extended battery of 3800 mah. but im still having bad battery life. ive tried all the basic things to fix this problem. (sync off, location off, 4g off, etc) i even put on airplane mode but i can only reach up to about 2 hours on screen time. my bro has a note 3 with a 3100mah battery. why can he last the whole day and i cant even last 5 hours on battery? i even tried using titanium backup to remove google now launcher and google search as this also eats up battery. what else options can i use. (i used wakelock detector and app permissions to stop wakes) thanks.

What rom are you using and which kernel? Also what settings do you use? Any overclock?

Thanks for the speedy reply! Currently I'm at resurrection remix 5.1.1 (latest) using fancy kernel r50. CPU over clocked at 1.3 (not a big difference) and govoner is ondomandplus. Scheduler is sioplus. And read ahead buffer size 1024. That photo is the amount of time my battery dropped a percent.... Sometimes I catch it slippin. And it drop 2 percent. Then when I lock my screen for about 30minutes it goes up 2%. And yes. I wiped battery stats. But still to no avail. GPU clocked at 512 BTW. I have the multi core power saving on too. Set to 2. I use greenify to sleep apps also. Any ideas?

The thing with extended batteries is very often their actual capacities are far less than what they quoted. I suggest you try getting hold of the official extended battery (I can't remember the actual mAh maybe 2100) as with it my phone could last from 2.5 - 3 hours of on screen time, depending on the ROM and kernel.

Was using CM11 M releases until the theme engine bug introduced in the recent M6 build. So I have been trying out different ROMs and SlimKat has been the most stable. The SlimKat stock kernel is good enough otherwise Fancy Kernel is a stable and better choice.

Here are screenshots of a day of quite heavy usage while connected to the WiFi with the latest stable SlimKat Build 5 with its own kernel, using the Galaxy Nexus official extended battery that is 2000mAh. 2 hours 45 mins with 30% left to go.
By the way I rebooted the phone twice to change the LCD density as shown in the graph.

I manage to get 3 hr sot and 1 day uptime with vanir and its stock kernel. Maybe the gpu @512 mhz and the "power hungry" io scheduler are killing it. Try some tweaking. A diffrent governor and tunables. Try Nephilims settings.

Wow I don't think it's very legit. It could be just above 2000mAh in real life and then couldn't hold as much charge after a while that's why the battery drained so fast. Not to mention the risks of using dodgy batteries [emoji46]
I think I bought mine from a Korean eBay seller for at least $30 or more. The battery is also NFC-enabled and comes with a back that added a bit of thickness so most gel cases could fit.

One other thing to note is that even with genuine batteries they will start to lose charge or can't hold charge like it used to after 2-3 years. That's why I think phones with removable batteries are better especially if you plan to use them for up to 5 years. You can just get a new battery after 2-3 years
