force your CPU to lower rate can reduce Power Consumption , e.g. 400MHZ is ok
turn off google sync and background sync , turn off wifi when not used
kill apps not in use
dim your screen
use the latest kernel, then ur android will last till battery is empty

thanks to @fajarep
Use the Neopeek's Android Ports ,it is a different way of intalling android and the battery works perfect!
more tips are welcome
how long you will get if you lower cpu clock???

a little longer as it is 400mhz . my friend says 200mhz is good ,but so slow
too bad the kernel doesn't have complete iptables modules, i need to have that. currently i'm using my own kernel..
the CyanogenMod 6.1 is wonderful , and much battery saving
So just inherited my dads OG Droid. Currently rooted and runs Steel Droid (Mod Version 9000) and 2.6.32.9_RZ Kernel.
Phone is overclocked to 1GHz (125/1000 ONDEMAND).
Like the title says, the phone gets about 5 hours and then hit's 5% and keeps asking me to charge. If I charge it overnight and unplug it when it's 100%, it'll hit 90% idling (while I sleep) about 3 hours later.
Running Programs:
DSPManager
Words Free
Facebook
3D Digital Weather Cloc
News & Weather
3G Watchdog
Videos
SoundHound
Pandora
Temp+CPU V2
Now out of all the running apps, Pandora, Soundhound, News & Weather, 3G Watchdog, Temp+CPU, 3D Digital Clock are all widgets. Temp+CPU and 3D Digital clock are the only ones that actually run, the rest are just there in case I want to use them.
These stats today are from using Pandora for about an hour over Wifi.
Any ideas? Phone runs fine most of the time but I have seen the occasional lag where you have to click something 10 times before it opens.
I used to have a pretty big problem with battery life too, but even though I think they are somewhat silly and annoying the Easy Battery Saver app helped me quite a bit.
Wifi and using the speakers are heavy on battery life. Not sure how much difference it will make but try consolidating your widgets and app shortcuts to as few screens as possible.
Also your CPU governor might be set to something that lets the phone hog through anything at the sacrifice of battery. When i set my CPU to Performance my phone runs like a boss, while setting it to battery saver I get a little more lag but more battery, obviously. Not sure how/if your ROM will let you change that but it's something to look into.
I got it set to On Demand which might be the issue. The kernel is a low voltage kernel. How do ultra low voltage kernels run?
I did a battery calibration, downloaded Advanced Task Killer (Battery saver didn't work well, I'd always have an issue with 3G not activating) and got rid of all my widgets. Currently charging it up completely, I'll check it out tomorrow.
So the title is incorrect, it says 5 hours and 5% left. I checked the battery info at 5%. It said 4hr 4x min. About 10 minutes later it shut off so I didn't even get 5 hours to a full charge.
I don't have high expectations but coming from an Alias 2 that had the extended battery (I'd get a week of battery with my use), this is pretty disappointing.
Well I can tell you now, ondemand is NOT good for battery, what that governor does is make it so the CPU will go from MIN to MAX speed slots depending on what the phone needs, AFAIK it doesn't scale with need, it just goes to max. So your phones CPU was running at max most the time which kills battery.
Can't say anything about your ROM, but I use simply stunning 5.6 http://www.droidforums.net/forum/chevyno1/177728-ss-5-6-2-3-7-incl-1-battery-other-goodies.html Which, with his low voltage 1ghz kernel set to the smartass governor, I get anywhere from 8-14 hours of battery life depending on use. Using ultra low voltage kernels depend on your phone, some phones have trouble overclocking to 800mhz mid-voltage (mid-voltage is considered to be the most stable, but use the most battery), others can overclock to 1.25ghz ultra-low voltage, which is very rare. I would say try out all the different voltage kernels and see which one works best with your phone.
Also task killer = MAJOR MAJOR No no! The task killer will kill the apps, and the android OS will restart them, using more CPU time and making the battery actually not last as long, I would recommend learning how to use the supercharger script http://forum.xda-developers.com/showthread.php?t=991276
Can't say much about the majority of programs you have running, but I've found facebook does not like to play nice with the Droid, also, why use the 3D clock when the Droid comes with a built in-clock app? Pandora uses a lot of battery, so running it w/ the ondemand governor is probably what hurt your battery there.
Not many Droid users left out there, but I was and still am an extremely avid Droid user, so if you have any more questions just shoot me a PM and I'll help as much as I can.
Thanks! I got rid of all my widgets and installed Chevy's ultra low voltage 1.1GHz kernel on smartass. I lost 20% battery pretty fast but let's see how long it runs. I've had no force close issues so far. I'm a bit tempted to go to 1.2GHz ulv.
How much does the ROM have to do with battery life? I really love this ROM and it's interface. I thought the battery life really only had to do with kernels.
I also got rid of the clock widget and put a default clock widget. What's the built in Android one? Is that the "Analog Clock"?
Sorry for all these questions, I'm pretty new to Android. Only had this for 2 days (~8-10 recharges...)
Its fine, better to question and learn then to just get mad and over it, and Roms have everything to do with battery, they are just like kernels, some work AMAZING on some phones, while others can destroy battery life.
Like my rom, I found the perfect one for my phone, I get 8- (been thinking about it more) 20 hours of battery life on mine and it has pretty amazing performance too with the occasional hiccup.
And I thought you had the clock app installed for an alarm, not for a widget, my bad. I don't use a clock widget so I wouldn't know.. Also, I've found its not very good to run many widgets on the Droid, as it has limited memory and can only handle so much.
Well I got sick of it and reflashed the entire ROM. CPU governer is set to ONDEMAND 125/1000. Only*widgets I have are a simple clock (like the iPhone lock screen) and power control. Gonna see how it goes. So far so good but I'm saying that because I didn't loose 20% overnight. If I can clear the day, I'm good.
googlelover, what CPU Governer did you find to work the best with your phone?
I have been an Android owner for a while now, with the Droid being my first. Until recently battery life had always been an issue for me. Undervolting has never had an effect over a 20% improvement. And this is only when it's in deep sleep. Otherwise, in very general terms, undervolting can require a higher current aka worse battery life if you use your phone a lot. With undervolting comes the risk of data corruption in your phones memory and SD Card. What really kills your phone is screen on time, wakelocks, CPU overclock, and signal quality.
The last you have no control of. But if you're overclocking 1GHz or higher you have to realize that's almost twice the manufactured clock speed. As far as wakelocks, this is when something keeps your phone from going into a low power state. This can happen because of a rogue app, a buggy ROM, or having too many widgets. I ran into a ROM a while ago on my Fascinate that would stay awake if you had GPS enabled. The best you can do with your display power usage is to keep your brightness down. Hope this explains a few things
have the same issue

I already told you, the smartass governor, and like I said before, ondemand is not a good governor in my opinion. There are way to many factors in battery life to have anyone else be able to truly help you with it, all our phones are different and it really just takes time switching kernels, switching ROMs, etc to find what works with your phone
Sorry googlelover, I forgot you already said that.
So update guys. I've been going a day (so like 18 hours) of use after which it finally hits the 15% warning.
What I did:
Basically I reflashed the ROM and started from scratch. Before reflashing, I wiped the user data/cache/davick cache etc at least twice just to make sure it was really wiped.
I reflashed SteelDroid 9.0 with the default chevyno1 lv 1ghz kernel and gave it a go with just a simple clock widget. Worked well. One by one, I'm starting to install applications until I can figure out what was draining the battery fast. So far, so good. If I can get 18 hours on a 2 year old battery, I'm going to be doing fine with my extended battery.
One thing I did notice was that the phone back by the camera (where CPU is) isn't getting as hot as it used to. Makes me think that the phone was at a high clock speed in sleep. Another issue may have been my CPU temp/speed monitor. It was probably poling the CPU stats every second which made the phone increase the CPU speed because it sensed activity.
Try out the ROM I'm using. I absolutely love it. The interface is phenomenal and it runs very well.

(remove the spaces to see it, I wasn't able to post links normally because I don't have enough overall posts).
There's probably other ROMS that run better like the one googlelover is using, but I can't use the default Android interface anymore after using this.

Don't forget not many roms have the default android interface, many have themes to completely change the look, if your happy where your phone is, great! But if you ever feel like your phone is slowing down again, I'd still recommend looking around and flashing some different roms.
Thanks, I'll keep that in mind. I'm only using this phone for another couple months. I'll be getting the Droid 4 when it comes out. Looks like a really nice phone.
I was wathicng youtube and had pluged in charger and popup came like your cellphone battery is getting too hot stoping the charging and i checked the cell and it was really really hot
whats wrong
i am using rocket rom and abyssplug
no overclock
Flash different Kernel .
Try to see if it happens with a 100% stock kernel.
I have same RocketRom v20 and AbyssNoteKernel 3.6 to but it never happened to me.
Only as I had AbyssNoteKernel 3.2, then it got too hot.
Just flash another Kernel like SpeedModKernel

Yes, you right!
I have had the same problem, but now i use Rocket Rom V21 and it seem ok.
Same here at start Note was fine when using 3G or charging temp used to be around 30-35C , but from few days even when on charging/maps/3g/ its getting very hot n temp is around 45-50C.
if i close all the apps n restart the phone n charge still temp is around 46C.
IM on STOCK ROM.
A lot of people find it possible to undervolt the GPU quite a bit. I'm sure it helps with temperature issues. I run mine @ 267 mHz / 0.75V (lower step) and 400 mHz / 1.00V (higher step) all the time. The phone does get warm when playing 3D games but never really hot.
Hello,
I recently bought this Samsung Galaxy SIII mini with NFC (so it's the N Version) and i am experiencing many problems.
I was excited to have it at the beginning cause i took it instead of a Mini Plus (GT-S5570I). But after a week i can definitely say that for my use, the mini plus's battery life was pretty more satisfying. Anyways, apart from the drain, which i'm trying to research about i have problems with the CPU management.
I'm using simply the OnDemand governor with Min at 200Mhz and Max at 1Ghz but as i can see from the System Tuner Pro app only one core (core 0) is currently working, going back and forth from 200 to 1000. The other core is completely deactivated. Some days ago i had the opposite problem, my cpu was always on at maximum and it heated a lot. This is a big problem because i can't control it and like this the phone is even worst than the mini plus.
I have tried many roms and mods, here's the list:
•Stock
•Stock Rooted
•Dmod V6
•BenzRom (actually on)
•Maclaw's last CM 10.1 Release (29th August)
•Maclaw's last AOKP Release (28th August)
•Going to try the Faust1.5
I have tried all of them (except Maclaw's) even with GoldenKernelv2 but nothing changed.
In Maclaw's releases i noticed a problem with the sim, in fact when i tried to import the contacts it said there was no SIM card, but RIL worked perfectly. I just need a rom that can give me really 18hrs of life with medum use (i use only whatsapp all the day, no gaming, no sms, hardly ever calls) because now i can reach 6/7 hrs....
Thank you in advance for the replies
Yesterday I successfully flashed my Samsung S5 Mini G800F with the latest crDroid and GApps (LineageOS 16, Android 9.0).
Before I was using LineageOS 14 or so with Android Oreo. Input lag got so crazy that I re-installed everything.
To safe some battey I've choosen as cpu gouvenor Izz moove with ReadAhead 1024 (16GB of internal memory) and I/O Scheduler noop. CPU is set to min 200 Mhz, max 800 Mhz.
It takes about 1 full second before the screen goes on when I hit the power button (phone already turned on, screen just off). I don't know what to do to get it a bit smoother / faster without having 0% battery at the end of the day when doing nothing on the phone.. It's still some kind of laggy bit way better than with Android Oreo.
Can I install a new kernel to this phone?

To be honest, I'd recommend either LineageOS 16 or 14.1 for battery and smoothness as well as stability. For smoothness I recommend using the stock 400 MHz as min freq (complicated to explain, but lower min freq is overrated) and AT LEAST 900 MHz max freq, maybe even 1200 or 1300 MHz. zzmoove governor isn't bad, but I'd still recommend interactive, it is always a solid pick for a compromise of smoothness and battery life. Regarding your question about other kernels: There are none as far as I know
The only Pie Kernels for the SM-G800F are Spookcity-P and Spookcity-P-Custom (included in crDroid). I don't know whether it is accurate, but my battery statistics always show Display as the main power drain. Maybe reduce brightness or play with GPU settings if there are options? Four Cortex-A7 cores shouldn't use too much, not even at 1.4GHz. Other than that, there aren't many options. Either get a new third party battery (first party ones suck), a new phone or just embrace it.
Another recommendation: Keep the read-ahead value at 128 or 256k, it doesn't really matter too much. What does make the phone a little faster in some scenarios tho is f2fs. Backup all data to a PC (including internal storage) and then navigate through TWRP to change data partition to f2fs, I don't remember the exact steps. This can make some things faster, but others a little slower. I didn't feel a huge speed increase, but it's supposed to help extend the lifetime of the storage. Of course transfer everything over to the phone after format.
I installed LineageOS 16 from Spook city , I think a very good build , how ever connected to charger or PC it lags a bit , but when on battery everything smooth .. I wonder if we can fix the lag connected to energy source problem.
