Appropriate steps to a better battery life?

Hi everyone! Long time XDA reader and I've had my Evo rooted for months. Now I have been dealing with its "poor" battery life for a long time and not really thinking much of it till I finally decided that rooting has to have some advantage for this. I average about 6-7 hours then my phone dies...
After doing a little research I read some people getting 15-20+ hours out of their phone with heavy use...I was amazed...I decided to try to get better battery life on my phone and this is what I am trying right now. I just want to make sure I am on the right path with it and that I am not doing anything seriously wrong.
-I am trying Cynogens ROMs - CM7 I tried for a day and that gave me about 7 hours of battery life...still no real improvments. I am trying Cynogens 7 Nightly 12 now to see if that works.
-I am trying different Kernels. Been getting them on the HTC EVO kernels page. Right now I am using stock HTC one.
-Should I try different radios too? Where can I go to find different radios if so.
-What order should I be installing radios/kernels/roms?
-I have donated and am using Set CPU now also and have the screen off cpu power really low.
-Am I on the right path trying out different ROMS/ Kernels/ Radios to optimize my battery life? Is there anything else I can be trying?

turn off gps when not need
data when not needed

Check out my sig for my full walk-through on battery life (I don't want to repost it here lol).
But you seem to be doing everything okay. My only hesitation would be to say make sure you're giving Kernels adequate time to settle into your phone. Unless something is HORRIBLY wrong with them, you shouldn't switch/judge them until at least two days in
Radios should not make a difference in your battery life.
Also, be aware that CM is NOT optimized for battery life. There are a couple of ROMs that will give you unheard of battery life if you would like though (Myn's comes to mind). It's a trade off though. CM is hands down the fastest ROM you'll run...but in my experiences is in the lower tier of battery.
Hope that helps

also when the newest version of ultimate Juice is released that will help you i have the closed beta and im glad to have it back and running

@Cheesy: I turn off all those things If I turn off "data" that turns off Exchange push right? I really need that on all the time >_<
@Green: Really? Myns is good on battery life? I tried that before and was dieing with battery. (Was getting my average 6-7 hours) I had that one for about 2 weeks. Do you think it was my Kernels that were bad then? Isn't Myns warm 2 pt sense based? The one I used was...I had thought sense UI drained battery more than CM for example that is just plain stock android gingerbread?
@Cheesy again: Ultimate Juice? Is that an app on the mkt place? How much did it help you? I'm willing to donate and pay for apps to support the devs if they really make a noticeable difference.
Another thing..when you install a ROM does it automatically install a Kernel too? Or are those 2 separate?

with UJ i get 18-19 or more on a full charge with phone being used 80% of the day .
with out i was changing out batteries after 9 hours or so ( i normally work 12 - 13 hours a day )
yes its in the market but gingerbread support is not public yet ( closed beta )
also check in spareparts for any wakelocks you might be having
for a sense rom myns are great so are Ava's,caulkins and Miks

Hmm Thanks Cheesy. I'll take a look at that.
So if I flash a ROM that is not Gingerbread...I can use that app. But Gingerbread is anything 2.0+ right?
I'll try out those ROMs too and different kernels...test them for 2-3 days.
Whats wake lock? I'll download that spare parts thing and see if I can figure it out.

I just recently started seeing great battery life with my rooted Evo. I flashed MikFroYo 4.5 with a stock htc kernal.
I use juice defender and that's it. I've been getting just over a day per charge for the past two weeks.
I wouldn't say that's with heavy use as a good 6-7 hours of that time are accounted for when I'm asleep. I do about 30-50 texts a day. About 10 minutes of calls and I check facebook and twitter all the time. My data use varies depending on the day but I do use youtube and pandora pretty regularly as well.

just make sure background data is disabled. accounts and sync>background data. I have no issues with battery life on stock sprint evo.
of course it is a 3500mah battery

My wife and I just bought two EVOs a week and a half ago, and I quickly became interested in improving the battery life on the phone. My first attempts were rooting my phone and installing OverClock Widget, and using minimal settings when the screen was off. With that change alone, and comparing to my wife's phone from a full overnight charge, my phone was able to make it 14-16 hours with moderate use. My wife's phone would die after 8-9 hours of moderate use. Granted, there's obviously going to be a difference between my moderate use and hers, but even testing with screens off and letting them idle for an hour, there was a definitive difference in battery consumption between our phones.
I went one step further and installed CM7 Nightly 12 just yesterday... already I'm noticing even further improvement in battery life, but the majority of those savings are when my phone is idle. Overnight, my battery only drained 7%, whereas my wife's drained much more than that. My battery has been at 39% for the past 3 hours at idle, so I imagine that with my version of "standard usage", I would be able to possibly get higher than 16 hours of usage per charge (can't wait until I do the full calculation testing tomorrow!).
Here are some observations I've had in all of this:
1) Check out Greenfieldan's list of battery tips and tricks. Some of these are very simple and actually had a significant impact on both my phone and my wife's phone (especially shutting off data and disabling auto-synch). I'm new to the forums, but this is one of the first things I checked out. This is a great place to start.
2) Battery consumption is obviously affected by how frequently you use your phone, and what you are doing with it. I say this because it's easy to read threads about what techniques work and see mixed results, but I don't see alot of people really admitting how much or how little they use their phones. I'd say I'm a more conservative user of my phone, but I still have my texting, browsing, and even occasional streaming, GPS using and general fiddling. So in other words, your mileage may vary with any given technique.
3) This is my personal opinion, but think about when you ideally want to be charging your phone, and try and anticipate usage around it. It sounds strange, but I've come to my own conclusion that an optimal charge for me (not necessarily possible, but optimal) will give either 12 or 36 hours of usage time. This is because I like to charge my phone overnight, so if I get 18 hours of battery life, I'm unfortunately wasting 4-6 of them. If I get 24 hours of usage, then that means that by the next morning, I need to charge again. So I plan ahead and charge at night, and use through the day. This was particularly useful when I first started with the phone and was getting a max of 8-9 hours. I'd know when to unplug, and how well it would get me through the day.
Anyway, at this point I'm rambling, but since it is still very fresh in my mind I wanted to share my thoughts. Hopefully this helps.
(Btw, apologies for the huge post!!)

Gingerbread is Android v2.3. Froyo is v2.2.

Sorry it took me so long to reply.
Anyhow, from my testing on mine and three other phones Myn's Warm TwoPointTwo has the best battery life (although some of them were right on par with it). Specifically his RLS 3 and RLS 4. Did you try Warm Z? Because the battery life on that ROM is no where NEAR his 2.2 ROM.
Also, Sense CAN be a major drain on battery. If you make it so it's not syncing all the time/doing the random shenanigans it defaults to I'd argue it's better than AOSP (based on my experience with both).
Yes, your Kernel might have been an issue. Do you know which one you were using? HAVS? CFS? BFS? Etc.
Just for my phone comparison, CM7 (which I am running now) requires me to charge my phone at least once a day. Myn's Warm TwoPointTwo was every other day/every day and a half.

You can set juice defender to turn on data to sync at set intervals; anywhere from 15min to every couple of hours. If you can stand to wait 15 minutes for that email then I would recommend it. I personally like not being interrupted every time I get an email.
Also, make sure your kernel and setCPU aren't trying to both control the same thing. I really like using a kernel with HAVS so I avoid apps that also try to modulate my CPU.
I've tried warm 2.2 and really like it. Although I think I'm getting slightly better battery with Azrael X 4.0 with netarchy 4.3.1-cfs-havs-nosbc and ultimate juice controlling only my data and WiFi connections.
Also,the 3500mah battery is worth every penny if you don't mind the extra thickness.

i owe setcpu and screen off seting for my battery life

I read Greenfieldan's step on the forum here about a week ago, and jsut the HTC Method of battery calibration alone changed my battery life completely.
I also dumped Advanced Task Killer.
In another thread, I rad that CM is the worst drain on a battery and I personally think the guy that wrote that is sadly mistaken. Even with all the steps taken in Greenfieldan's guide, Sense based ROMs are battery killers. They are the worst, by far, and I average battery drain at about 15-20% pr hour, even with screen off.
The #2 killer, is having your screen on. Waiting for that next text to come in with the screen on is not worth it, so turn it off when you're not using it.
With the setup in my sig, and moderate to heavy use, in 12 hours, I only drop about 25% with a Sedio 3500maH battery.
With Sense, like I said, quick battery death.

I'm using CM7 - Nightly 12 right now + Stock Kernel...I also have set cpu to change cpu usage when screen is off.
This combo was my first combo I started trying (2 days ago when I posted this) to test for increased battery life. I followed what some of you guys suggested and let it "work into my phone." Instead of giving up after 1 day of test.
Results! Just yesterday I had my phone on for 14 hours and it was at 18%! That is a HUGE improvement. Right now it is at 65% and I've had it on for about 5 hours. That's really long compared to what it was before! Before I tried changing the ROM, kernel and using Set CPU I would be at the red right now or around 15%.
Thanks you guys for all the suggestions! Any further advice would be greatly appreciated! (Only sad thing is that my GPS doesn't work with CM7 - Nightly 12 >_<...) Other than that I love it!

Batter life pre and post root/Midnight ROM 4.2

The Short Version:
Stock froyo downloaded from Samsung's website- My battery would die at work at around 1600, after being unplugged at 0600. We will say it lasted about 10 hours. With minimal usage, with looking at my battery reports my screen was used for maybe 15-20min.
Post root/Midnight ROM 4.2- it is now about 1600 and I have about 90% battery life left with 22min of screen time being used with obviously minimal usage after 10 hours.
Long version:
I was getting fed up with my battery life on my beloved epic and not being able to use it at all. So I decided to do some research and figure out this rooting and ROM flashing business. I KNEW it was not because of the apps and such that sprint blames the poor battery life on because I would monitor that and not use any at all while at work just to see and prove them wrong. I have the same apps installed post root as I did pre root with the same sync settings.
So in other words it is highly depressing that they put so much crap on this phone stock to kill the battery life with not even being used.
I am so happy now, I can actually use my phone without having to worry about being dead in 2 hours.
Thanks for everyone’s help with my flashing question and thanks for this great website as a resource.
Time to try out some different ROMs!

Sounds to be like your phone might of been fighting for a signal or something, maybe a PRL update would of fixed it... I was getting well over a day with the sprint rom.. and now with ACS Rom I get a little better.. but not much..
anyways.. congrats

Hows your battery life on sense to GPE m8

Hey guys
How is your battery life after changinge sense to gpe ? Mine sucks quite a lot. Maybe a half day on average usage. On sense I got a full day.

Keep! I am also very interested in it!

I didnt convert to full blown RUU GPE. I am however using stock 5.1 ROM from the GPE. I get around 4hrs SOT with my use (im not a heavy user, never play games). Again this depends to each persons daily use/signal/services, etc. On sense I think I would get maybe around 15min more SOT. not much of a difference. Keep in mind there are many variables (I had a time that Google play services was draining my batt a lot, so these variables are not ROM related). so the best way to compare is to try them both for at least 1 week. For me, about a month ago, I think I saw minimal better batt in Sense. I wouldnt expect dramatic improvement.

Android 6.0 Marshmallow battery discussion

This thread is for battery life discussion of android 6 Marshmallow.
I took the plunge recently and installed cm13 nightly on my phone after a couple of days with sultan's cm13 ROM. One notice that the android team really got the battery optimisations right this time especially when coming from android 5.1. The cell standby and android system bug is now gone and the phone can now be in standby for a long time. My usage pattern is browsing, reading in Adobe reader, listening to mucisc with bluetooth headphones, facebook, wassup, some youtube videos, sms and few calls. I play farm heros sometimes but I don't play graphical intensive games.
Here are 2 screenshots of my phone. It was charged to 100% at 8:00am on 30/11/2015 and it still has 41% left as at 10:00am 02/12/2015 Granted I have only used it on wifi and I configured wifi to automatically disable 5 minutes after the screen is off.
You can post you battery life too.

If a moderator deem it fit, he/she can close the thread but I felt it will be nice to make a dedicated thread for Marshmallow instead of looking through a big thread to get the relevant information needed for a particular android version.

yes.

It still sucks on mobile data. Nothing changed from Lollipop in regards of mobile data battery drain and i wish google could do something about it.

That's it! It's still on LP niveau

i had around 2 hours of screen on time and less than a day's battery life. The MMS also didn't work with WiFi connected, so I switched back to CM12.

I finally charged the phone today but not before I took a screenshot. My usage is not heavy at all so for heavy users, I guess the SOT will be longer but the total number of hours the phone was on will be lower. My usage did not change form that of 5.1 but I can definitely see a great change in standby time.

Still doesn't beat out KitKat in terms of heavy usage IMO.

The performance(yield) of the battery essuperior to android 5.1. The cycle of load lasts approximately two hours more of screen.

Try Omniron Herna build, it does wonders on my phone regarding battery usage
Sent from my A0001 using Tapatalk

6.0 has the same battery life as 5.x for me. about 4-5h SoT.
KitKat and early 5.0 builds were clearly better with 8h SoT

Currently running Sultan's ROM CM13:
My battery life has hugely improved when I'm not touching the phone, no one app is draining way to much battery while not in the foreground.
There is one problem some people including me have been experiencing which is that Wi-Fi doesn't switch of properly and drains the battery, the only solution I found was to reboot the device after switching it off.
Not sure if this is a CM problem or the specific rom but not AOSP.
But apart from that battery life is good.

On sultan CM 13 CAF
Getting 4-5 hrs of SOT

Still waiting on a fix for mobile radio active. Had to go back to KitKat after a year on 5.x and a week or so on cm13. The difference in battery is staggering. Here's hoping Google actually finds a solution for the drain, otherwise I'm gonna have to stick to KitKat until I get a new phone.

I dont worry much abt battery charge ..currently on CM13.. dont see much of difference ... expect charge to last for 1 day.. connect to charging when home

Tech guys suggest me best battery rom for OPO don't fun with me by saying cm11s 44s. Almost 1 year stick to cm11 I need some latest android version in my device,
I'm new to xda
Thanks in advance!

Just stole myself this glorious phone yesterday (not really.. got a smokin deal) after 3 years and a month on a Nexus 4 that was left stock the entire time. My OPO is already rooted/unlocked so I'm trying to test out and find the best rom for battery life as both of the cm lollipop and marshmallow roms I've tried are about equal in terms of buttery-ness and just stick with that rom indefinitely.
Is general consensus that cm11 kit kat is far superior to the later cm roms in terms of battery life? Which exact rom would you choose as the last rom you flash onto your OPO ever?

S10+ Bad battery life, maybe a new rom?

Hello, I am experiencing some issues with my battery. I replaced the battery with a genuine one directly from Samsung. It is quite better than the old one but still can't get over 4-5 hours of SOT. And my phone does not last to the end of the day, often have to plug it in at work or school. I have the newest one ui 4.1 version. Should I downgrade do an older version or install a custom rom? Maybe also recommend a Rom for s10+ that has great battery life? Or is this just a software bug/glitch? Any help appreciated

Either optimize what you got or go back to what worked (easiest). A custom rom opens a whole new can of worms... really it's your call. Bigger, radical changes will require more of your time to try and get it running right.
Upgrades/updates can and do break things.
This stock N10+ is still running on Pie. It's current load is over 2 year old. Still fast, and stable with minimal maintenance.
