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!!)

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!

Battery life tips?

My nexus 4 has dissapointing battery life, can someone please tell me any tips to increase the battery life? Obviously, lower the brightness, dont have too many apps running, try not to browse on chrome for too long, etc etc. Does anyone use any of the battery saving apps out there? Any tips would be appreciated. Thanks. Also, I dont understand why there are no mods/cases with an extended battery. Obviously the battery is not easily removed but I'd be fine with a thicker nexus4 if I could double my battery life.

root it and run custom ROMs and kernels, undervolt it and whatnot.
You can just buy a portable battery pack you know.. They aren't exactly expensive and serve the sane purpose as an extended battery case.

When people say that such device has got a disappointing battery life.. I wonder what it means. If a battery offers a sot of 8hrs..would this thing satisfy all?
I've used S3 which people say has got great battery life.. I got more or less the same battery life in s3 as i get from nexus 4...
Anyways..trying custom kernel and undervolting.it could give you better results..

Agreed. I have friends with s3s, one x and iphone5, and I honestly do not think the battery is bad at all. I'm pretty sure the battery lasts longer for me than for them. And I'm not one for "disabling features" either.
I'm running wifi/data both on and I never manually disable anything. My GPS is on 24/7, and I have all tracking options enabled (for google now). Using auto-brightness though. Still get 4h SOT and I stay 30+h normally without a charge. I do not game alot on my phone though!
I recently re-flashed google stock images (4.2.2) and franco's kernel. Also undervolted but if I dont get any "better" (in terms of heat) results I will definatly remove the undervolting.

This what you doing is putting up one heavy burden on the battery.Never disabling wifi/data & GPS on 24/7..Still getting 4Hrs sot out of 30hrs total battery life .If this is not great than i wonder what great would be..There is only Razor max which is gonna satisfy in terms of battery
PS->If you game a lot on Nexus 4,then the battery wont last longer

Guys u can try deep sleep battery saver app aka ds battery saver.....it puts your phone into deep sleep as soon as screen goes off.........getting 10+ hrs on single charge.......mhav a try

Have you tried Battery Guru? Developed by Qualcomm specifically for the Snapdragon S4 to improve battery life

You can try greenify, I believe the concept of this app is great and overnight on WiFi and the rest left on I loose only 2-3 percent. And wakelocks are pretty much gone.

Terrible battery life.

Hey everyone. Without further a do, I am saying that my N4 battery suuuuucks really bad. Started on stock rom, flashed Chroma w/ latest franco kernel. Nope. Still lots of drain (slightly better overall, but nothibg major). Then flashed hells doctor kernel. Nope. Lots of drain when screen is on, but stable with screen off.
Honestly, I've seen people getting 6h on screen time. And everyone says that these kernels and rom can increase battery life by a margin, while mine stays the same.
Oh and there is a thing. Ive recently broke my stock charger and now using apple's ipad charger. Mine was 1.2 A and the one from apple is 1 A. Is this is an issue we are looking for?
Or its just a 2years old battery running out of its life cycles...?
Thank you!

Nexus 4 battere sucks really no matter what you plus your network coverage may impact vastly on performance. Anyway given the battery is 2 years old, I would say it's gone even if it says it's good but again it depends on your usage like continuous tethering or other heavy activity that makes the phone run hot

Well my usage can be heavy surfing on FB, Instagram and definetely FB messenger. I often use chrome and mainly everything is done under Wifi.
According to my screenshots, you cannclearly see that shes (battery) is ok when screen is off, no drain and etc. As soon I start using it it drains A LOT. Almost 90° angle on diagram It's crazy.
Plot twist: To prevent spam on the XDA forums, ALL new users prevented from posting outside links in their messages.

Yes, i have a new battery which was working well, but I flashed factory image 5.1.1 xxx47v and the batt life is really horrible now.
It's easy to replace the battery, I recommend taking out the sim card tray before taking the back off though.
I haven't been on here for a long time, whats the best rom, for batt life. I'm willing to go back to kit kat if I have to .

Also note that some of the screenshots with 6+ hours of SOT the user has handicapped their devices (disable 2 cores, lower max cpu/gpu frequency, etc).

Yes, I've seen people underlocking, undervolting etc. But that's not what I am planning to do with mine N4. Neither I'm hoping to have 6 hours SOT. 4 would be SUPER COOL. And that seems impossible for my device

Bad battery life on all phones? A curse?

Hello, so okay I agree the title is a bit too dramatic but I'm veryyy frustrated, so basically I've owned three android smartphones so far:
Samsung galaxy grand prime ve
OnePlus X
OnePlus 5
(a steady increase in specs)
And I have a question: why can I not get reasonable battery performance on any phone? On my oneplus X when I bought it, for the first few months I used to get 2.5 SOT and then months later I started getting barely an hour (45mins). No matter which roms or kernels I flashed, it made no difference. Battery saver on? No difference Greenify on? A small negligible amount saved...
Infuriated by this I finally came to buy a OnePlus 5 which I thought would put an end to this. However here I am, full of my battery saving habits still in me (which I have done so much research on to make sure they don't make it worse, trust me, I could write a battery saving wiki) and with a draining oneplus 5 in my hands. I've tried different roms and different kernels but still the same bad problem : a DRAINING BATTERY... I can get through a day with 3hrs SOT if battery saving mode is turned on but with a normal stock OOS I could never. I don't understand... I've tried BBS and GSam to try and find the source of this and still nothing. So I have resorted to the unofficial RR which comes with Lighting kernel which I have underclocked and use with battery saving mode on (not android's, ex kernel manager's one). So I have finally turned to xda so someone may be able to help me.
Cheers
Ps: I don't believe I am a target of the NSA and I have a special phone that is customized to track me...

I'd be looking at the apps you haveinstalled... Sounds like there's something running in background eating away at your battery life...
Or it's an energy vampire living in your home....

I am getting radically different battery performance with this phone day to day. One day it'll get a solids like 6.5 hours SoT and others I'll get like 4. Various issues it seems. Shouldnt be that hard to get consistent battery life.

Agree with above. Only common denominator here is you / your apps. But, stock+magisk with franco kernel and the app naptime is enough for me to get 5-7h sot out a full battery, but usually it's half full when I go to bed

You've mentioned that you tried many things to resolve this but I'll go ahead and tell you the things I use to make my battery last a little longer (hopefully there is something useful for you)
- Greenify with Magisk Module
- ForceDoze
- Location almost always on battery saving mode
- Force Doze for Google Play Services Magisk Module
- if WiFi is on, data will be off, and if data is on, then WiFi is off
- Bluetooth is always off if nothing is connected to it
- brightness is kept relatively low/halfway at most, the majority of the time
Running unofficial RR with Lightning Kernel v11 (1000hz version)
All this combined gives me roughly 9-9.5 SOT (about 140 apps installed)
If I forgot to mention anything, I'll edit it in here!

I've been very careful with my apps and I can't see what could be causing, I've tried third party Facebook apps instead of the official one for example and there's nothing strange installed.

Try with basic steps. Factory reset then:
1) Have totally stock OP5 - no "battery saving tricks", no apps. Run a bit. What is SOT? If less then average of 5-6 hours - either you have a "curse"/NSA tracking you or defective hardware.
2) Install your "battery saving trick" one by one testing after now and then. Are there any improvements in SOT? If yes, then write your wiki page, share your findings . If not, write your wiki page and tell us what application is a culprit.
3) Rinse and repeat until no more application left to install or you got bored.

I'm getting incredibly poor battery life after the latest update. I haven't let it fully deplete yet so maybe it just needs recalibrated?

There`s alot of sstuff activated on your 1+5. Try turning it off and check the SoT afterwards. Also some people were complaining because their Android-System was consuming way too much energy.

Battery life

I just got a LeEco Pro 3 (US version) on Amazon, put on lineage 14.1 on it, and for a device with such a big battery, battery life is atrocious. I'm getting estimates of less then a day. Is there a kernel or ROM that will improve this?
Sent from my LEX727 using Tapatalk

I have had Pro 3 for one year, running 6.01 with Nova Launcher. Battery life is not nearly one day in my heavy usage.
But, have Le Eco Fast Charging Battery, which gives me constant juice.
I probably use 2 full charges a day.
How hard is it to flash ROM you are using? Stable? Difference with stock?
The chip is fast, good storage, RAM.
Good luck.

I had the same problem with that rom that's why I switched to Omni. Much better battery life.

Is Omni still under development? I kind of want the October patch at least, as I use an open wifi portal and also want to use my bluetooth full time for my smartwatch, and live in a major urban area where if any exploits of these vulnerabilities is in the wild, they would be here.
Edit: looks like it is under active development, I spotted right away the KRANK patches: https://omni.cmxlog.com/7.1/zl1/

Sorry to say but for battery life Stock based ROMs are the best. I've found paranoid Android and Omni to be two of the better nougaty ROMs in that regard. I have some suggestions to help. Use kernel auditor to change parameters. Set first cluster to 1280 second to 1000. Schedule tasks on awake cores. Set GPU to 520 max and change governor to simple ondemand. Change io scheduler to Noop. I can get a day and a half of moderate usage.

I have an x722 on the Banggood vendor ROM and my battery life is pretty good. However I have my phone in Airplane Mode all the time with Wi-Fi enabled, and I've removed pretty much all LeEco applications. I mostly browse the web on the phone (very light text-based pages with few images, if any) while listening to local, offline music. Yesterday I was watching a bunch of 480p Youtube videos (in Chrome, stupid YT downgrades quality in mobile browsers) and my battery life got a bit low, around 70%. Okay, I guess. I think [email protected] YT would cause your battery to drain a lot quicker, especially if you're using the official YT app.
I keep my screen on a fair bit while commuting, but I don't use data; I just read offline pages. Maybe you should try going back to debloated stock, and then compare battery life on both ROMs. The issue could also be a rogue app. Use Greenify.

Well, yeah. Any phone with a SIM in it is constantly searching for a signal. But if you really want to know if there's a significant difference, test the phone's battery life with just Wifi enabled. If you're still getting bad battery life, it's something else.

I think it was the ROM I was using, LineageOS 14.1, using the new Paranoid Android Nougut (PA 7.3.x something) ROM, I'm getting two days of battery life.

Same here my findings exactly!

I appreciate all Lineage is doing for ROM development, but it seems others have better kernels or something. Is it all in the kernel, do you think, or is there some battery optimization going on in the ROMs themselves?

People try to say that custom roms aren't as good as stock. I have been having nothing but stellar battery life on Paranoid 7.3.1 I can't much more than 6 1/2 hours and counting with extremely heavy usage. Was also taking photos all day

Man I envy you guys so much, I own the x727 model and I'm eager to flash a custom ROM on it but I don't know how and am mostly afraid to do it :'c

I think your eyes are screaming with minimal brightness. Only just for record. Light browsing maybe only seen on...

Ok

Is there any bug on latest Paranoid android ? I'm planning to flash this when it comes 2 days battery life like you said b4

Reduce CPU usage, use Kernel Adiutor app, set max not 2140 Mhz, but 1400 Mhz, etc, I did this on my old phone 4.2 android and I usually had 1 week usage with 2500 mAh battery.
I still don't get what is little and BIG setting for CPUs.. I set them both lower.

Yes you are right, lower the max of CPU speed, normal 80-90% app run at not even 1000MHz. If you want more battery lower both BIg and LIttle core max speed down I can't see it mak ethe phone slow/lag or anything like that.

How has your screen only consumed 1k mAh ? I'm on stock rom and my phone consumes close to 2400 on a full charge
