Tips to GREAT Battery Life!

Here are the settings I'm running on CM7 to get amazingly bananas battery life (with the display being on for about 5 hours!)..
1. Conservative governor: 245mhz - 1017mhz in CM7 settings
2. Install the 'BatteryCalibration' app from the market. This app caused the single biggest improvement for me after having flashed so many roms and never calibrating the battery. If you've calibrated it before though, I don't think it'll be very useful for you.
3. Install 'NoBars' from the market to automatically turn on airplane mode when you have no service. (This might be useless to some of you if you always have a signal; Very useful in NYC subway though)
4. Use a 2G toggle widget to have the phone only use the Edge connection when you only need it to receive calls/ texts and don't need the high speeds. I use the toggle widget in the CM7 notification bar. HUGE battery saver.
Give these a shot and let us know how they work for you

I've reached the end of my day and here are my final stats..
Mmy display has been on on over 5 hours now and I have 5% of the battery left. Seems more than good enough for me. Hopefully it will be for some of you too
Edit - Updated with more recent stats

Question: It's cool that your display was on for 3 hours, but what did you do as far as app usage??
If you did use your phone "a heck of a lot" wouldn't some apps like "internet" "maps" or something show up on the battery use %'s???
For example, currently, other than phone idle, cell standby, voice calls and android, there's also internet, mail, maps, and other apps that I used today alot.

Good observation. I have no idea how android chooses which apps to show on there, but I think it depends on the ROM? I remember on Iced Glacier cell standby would barely use 5% of the battery and on CM7 it uses >40% consistently. Idk.
Maybe what those apps used up here was nothing compared to the display, wifi and phone idle time.. Just a guess.. But I did use the browser and xda app and listened to music via the Rdio app running in the background several times throughout the day, and sent multiple texts and have had my wifi on for about 5 hours now. I can't really find a menu that would show these statistics except in the Spare Parts app, and here you go..

I got 17 hours just yesterday with 9% left with moderate to heavy use (texting, web browsing and ps1 emulation).
I didn't do anything besides use faux's kernel with the smartass govenor. I have the max speed overclocked to 1.8 as well...

Nice. I just got over flashing new kernels for a while since the stock CM7 one has everything functioning perfectly and new kernels would improve on something but mess up something else in my experience.

I can't seem to find a 2g toggle widget that works with Royal Glacier. (one touch, I've found a few that take you to settings) When I was running Royal Ginger I would always use the one that came in the notification bar.

Wifi status is also a good app to remind the forgetful to turn off wifi when they leave the Area.

This is GREAT battery life... i wonder what word i'd use to describe mine.
i Pulled my Phone off the Charger this morning @ 7:20pm EST. Now it is 3:13 EST. and i've got ~50% left. So thats what like. 7 hours

neidlinger tap that 'screen on' tab and lets see how long your screen was actually on for?
Either way congrats, and it's good to see ppl are over the battery issues.

since my last boot. 8:10AM when i loaded the new CM7. 1h 1m 59s.

Unless I'm missing something, the 'BatteryCalibration' app won't increase your battery life. It will just help to get a more accurate reading of your battery level.
I've played around with different roms and kernels. And yes, they do have a small effect on battery life, but not all that much.
Here's my tip for battery life. Get on ebay and buy one the of the cheap packages from Hong Kong with 3 batteries and a standalone charger. Like this:
http://cgi.ebay.com/3x-New-1500mAh-Battery-Charger-HTC-Mytouch-4G-Merge-/290556738794?pt=PDA_Accessories&hash=item43a687fcea
I bought a similar package a few months ago and now I never have battery problems. Nor do I have to take a chance on wearing out my micro-usb jack like I've seen happen on a lot of other phones.

Maybe. All I know is my battery increased dramatically after running that app once.
I measure battery life by how many hours I am able to keep my display on before it dies rather than how long after it comes off the charger (like nedilinger does). My battery used to die after about 3 hours of the display being on. Now it consistently lasts 5 hours.
Anyway, I was just trying to let others know what I did to get a really good battery life on my phone thinking it might be helpful. Apparently that's not appreciated. Thanks tho.

How long does 1 of those batteries last?
Sent from my HTC Glacier using XDA App

simple way to get awesome battery life without any extra steps is to install RoyalGlacier 1.6, that's all. A couple days ago I ran my phone for one and a half days before charging it again, and it still had 14% battery left. RG is pretty much a polished version of CM7, runs blazing fast and smooth.

Better than what's reported under CM7. The battery life I posted above was on RG.

you say you don't sacrifice 4g but you admit you have a 2g/edge widget?
To me "not sacrificing 4g" means not ever turning it off, maybe i'm mistaken
I had battery issues, I'd have to charge it mid day else it would die. Juicedefender helped a bit (claimed to do 1.7x battery life) but I uninstalled it, rooted the phone, and uninstalled a bunch of stock apps
For some reason now my battery lasts a very very long time, don't know how or why that is. I also admit I don't use it as heavily as some people, but my habits have not changed and I did have to charge it mid day (like i said) even with little usage

Obviously, it's hard to say without describing how I use my phone, but I get probably 10-15 hours of medium-high usage. I probably get about 4-5 hours of talk time. I'd say the Chinese ebay batteries probably last 80-90% as long as the OEM battery. Quite decent considering the price.

My earlier thoughts about the BatteryCalibration app could be wrong. I don't really know all the details about how Android battery calibration works. I just assumed that it simply learns about all the bad spots in your battery so that your phone doesn't instantly jump from 80% to 30%. I also assumed that the phone would die when the battery had no power left, as opposed to when it says 0%, but maybe that's not the case. Regardless, if it helps you, more power to you and I appreciate you sharing the app. I didn't mean to come off as an unappreciative ****. If I did, sorry bout that.

[Q] The most optimized rom for battery life

Hello
My One S' battery is dying so much that i now have to charge it twice (!) a day to make it through.
Im therefore searching for a rom, that has the best battery saving features out there.
Can anyone recommend any such rom ?
Thanks !
~D

If the battery is old, change it. That will probably fix a lot of things.
CandyKat+Insanity. Best battery life for me so far.

I have been running CandyKat + Insanity for a few days now with stock brightness settings (which is actually really bright). Along with Greenify.
I still get good battery life. Probably around 3-4 hours screen on, and all day use. To my surprise, I do seem to get long run times with video - I tested 5 percent per half hour. So if it continues - 10 percent per hour. That's a long time - that means the phone can play movies for 9+ hours. I was using the Snap movie viewer.

You need e very slim rom.
Uninstal what you don't need. Stop apps you don't use.
In particular wifi & bluetooth (large consumers).

Great battery life with MM update

Hello ..
I am getting amazing battery life since I got 6.0 .. Before with lollipop I used to get around 5 hours on screen time. Amazingly though I hit 6.30 hours on the first day after update, and this with wireless, mobile data and Bluetooth on. And no data saving and screen on 70% which is amazing.
Good job Motorola

Excellent I would say
Excellent batt life with this new update very impressive how a software help the hardware to accomplish that task.

I replaced my STYLE and got a new one two days back. The old one would be dead even though it has 80%+ battery.
The current one is pretty good compared with the old unit. I got 4+ hours of SOT and I was on 4G and WiFi all the time. Was using it heavily for browsing and chat.

This is not bad at all. What I am saying is after MM update battery life increased about 1.5 hours extra SOT

Perhaps the update fixed something else? Looking at the MM update from L, there appears to be nothing besides Doze, which only works when the device is still and not used. I notice perhaps 15% better battery life if using the device sporadically during the day (medium use for me). With heavier use, I notice zero difference so far.
I was hoping some kernel adjustments were made, but the device spikes with heat about the same. I first thought it was less, but notice the same apps get the device very warm to hot (the GPU is over it's head with 1440p). Standby time is a lot better though, but only a significant improvement if lighter use though the day (so Doze can be a factor).
Usage is relative only to the user though

How do you get such great battery performance? I barely manage to get 3 hours SOT.
When the device is idle there's no drain, i only lose 2-3% overnight. But when the device is active the battery drains very quickly.
Tried a lot of battery saving stuff, greenify, powernap, and so on, but no luck.
I'm on MM stock rooted. Having a lot of apps installed. May this be the culprit?

If 20% brightness or less, all you do is web surf and a little Youtube, with good LTE signal or wifi and VERY little use of apps that force the GPU to push 1440p, you can get five hours. Everything is relative to the user. That's it.
Counting stock apps, I have 395 apps and 5GB free (64GB model). based on MM battery report, I have no apps that are background battery demons.

Are you talking just 1440p video in general or are you talking 1440p games?

I'm lucky if I get 2 hours of SoT. I can't tell if Android Wear is eating my battery or if it's Sprint, despite having a decent signal. Bluetooth and Cell Standby are chewing up the majority of my battery power. I think the network management is trying to shuffle my phone between their three frequencies and while at work, I can only get on the 1900MHz PCS band due to having to use a repeater.

Some games and apps run at 1440p and choke the GPU. They stand out by running very warm to hot and drain the battery more quickly.

Yes the apps do drain battery.
I uninstalled one particular email app that alone would drain 6% daily!
Anyway this time I got is without gaming. Mostly chatting and browsing and a lot of movies (vlc). I think that day I watched not less than 3-4 hours of continuous movies on the phone.
The only thing I did differently than before is removing unnecessary app permissions and notifications. Other than that I have done nothing. Like I said I do not try to save battery because I always have power source near by, but this 6.30 hours SOT i s awesome I tell you.
Based on my little experience with Android some apps will screw up the phone for no reason. First time I got the phone I got around 3 hours SOT with so many unneeded apps, and I did not know which app is draining my battery so I formatted the phone, and started installing apps one by one and watching the battery. And I managed to hit 4-5 hours with lollipop. Now with the update I got this and I was shocked.

Fully back to stock, unrooted, bootlocker relocked.
Upgraded to MM via OTA.
Installed all my apps via Play Store. Until now, i always restored my apps via TiBu, including data/settings.
I'm curious if my battery life will improve.
Will post the outcome, if any
Cheers!

A lot of the time my phone is just sitting on my desk. It used to say I would get around 1-2 days battery life from it sitting there doing nothing. After MM it says there is 8 days left. I have had it unplugged all day and even with some moderate use I am only at 95%. The doze mode really makes a big impact in stand by times!

I think it did do something to the apps. The way you can block apps from getting access to location or other services is pretty impressive. I love that as I hated that apps would have access to everything on my phone and I cannot do anything about it. Now I can and this particular feature made me love Android even more after I switched two months back.

Is there something wrong with me. I only get 2 to 2 1/2 hours battery tops and actually I've tried amplify (paid version), and power nap and they don't seem to help much. I have only got 3 hours once since I got this phone. Is it just AT&T maybe?

I'd like to mention something else. Probably not related at all, but ..
My old MXS was a faulty unit (as I mentioned in my previous post). Once I got a new replacement, I have not yet charged the phone using Turbo Charger. I am charging it with Mi Pad charger (non-turbo). Yes, it took about 2+ hours to go from 30 to 100%.
Old MXS was always charged with turbo charger and I was getting pretty bad SOT and the baterry would drain as fast as it would charge. Does it have to do something with using a normal vs turbo charger?
I stop pretty much all background services and apps not in use. The only active applications are firefox, whatsapp and VLC.
My screen is set to 50% brightness with adaptive brightness ON. Moto X display and attentive display is ON.
Non-root (planning to root soon) and Moto ROM.

Probably yes. But i would charge on non turbo for two weeks so that I get definite data for comparison.

Less than 3 hours is not good bro, really anything below 4 hours is just bad. You better figure out what is draining your battery, or maybe it Is a bad unit?

what difference does it make if it is charged slowly or not??
It should not matter, if the battery is not keeping the power that means it is defective, nothing to do with slow or fast charging.

Don't worry about battery life until 2 week after !!!!

Hi everyone , I'm new in the community but I already found that this is one of the best phone forums online , normally you come here for help because you have a problem right ? But today I'm just here to give an advice, I notice that many people complain about the battery life on their new phones , I had the same issue with my note 5 , I saw a video on YouTube and the phone showed an estimation of battery usage of 18hours while mine only showed 9 , I immediately thought that my phone was broken or something until a month later I realized that I was getting more than 20 hours of battery usage , when we use a phone for the first 3-5 days ( specially android) we can't expect it to be fully optimized because it's still learning your behavior and phone usage, just by installing a new app your making your phone to "learn to do something new" when I got my s7 edge I didn't expected to have great battery life , I was constantly installing and removing apps , flashing Roms and trying themes and etc. Now after a month later I use my phone on a pretty standard routine , I used package disabled but it only made my phone laggy and slower , so I decided to use my phone on the stock way , I running all stock , ( only disabled the apps that come with the phone that I don't use like power point , Samsung gear and health...) and after I did this I noticed a huge bump on battery life , I went from 12 hour of usage and 4:30-5hours of SOT to 30hours of usage and 8hours of SOT
After installing a custom/stock rom make sure to drain the battery completely just once to calibrate it !

I can never get more than 6 hrs sot.. Gonna follow your tips and write back in a week or so. Thanks for sharing!

Feel free to use package disabler, it was a lifesaver to me with my note 5 but not on the s7 , but other users report that has been really helpful other thing you could try even that the impact will be minimal is using a dark theme ,

Also don't update to the newer firmware if on Exynos. Seems to hit battery life by 25% or more as android system goes from around 5% to 15-20% battery usage.

with newer firmware you mean the may update?
with me it was the other thing around, in the beginning it was quite good but now, its worse. is it because of the bright sunlight or the phone getting hot because it was around 30 degrees almost?
you see...screen on time about 2 hours
most active battery drainer, android itself

Only way for me to get 4 hrs of sot i have to plug in to charge and disconnect before i get to 90 cause then it seems to thing its fully charged and battery meter resets (on battery).

The thing is, I have disabled half of the system already, but it just feels like it's doing even worse than before so I'm leaning back on running stock again.

Yes original firmware much better battery than the update

It didn't work either to me , this is what I think , it may sound stupid but it could be the true cause , I think when you use an app like package disabler to disable things on your phone and then you accidentally touch to open the app or setting disabled the phone will think "what's going on here" why is this disabled? And it maybe tries to access/ open the package again and again causing it to actually drain battery !, You could a cache wipe , it worked for me , I follow all guides to extend battery life using package disabler, custom rom , flashing zips to delete bloatware but none of them worked for me , instead I went all stock ,and after installing the stock rom I did a factory reset and them the cache wipe, it worked flawless to me , the phone now works like a charm , no overheating (maybe I don't feel it because I got a case ) but the point is try to find your own solution , every s7 edge it's unic, maybe a simple reebok on your phone could resolve all of your problems , and a very important thing !!!!! If you flash a rom /kernel make sure you let your battery drain completely just once to calibrate it!

I wiped nothing, stock rom latest APD1 , aod off now but on sometimes , location on, sync on 3 emails, disabled a few things with ez package disabler. Browsed the net for all the time the screen was on, WiFi on while screen of and on for atleast 2 hrs while using line messenger and used Spotify for around 30 to 40 mins. This is sot and battery usage.
I don't know how u manage to get such bad battery life, swear u guys r fu#*ING about with sh%t too much, let it settle.

Great battery life , you can easily achieve 3 days of battery life and 8-9 hours of SOT I guess which is great for you , just consider yourself in the 5% of people that own a phone with no battery issues , I'm happy with my 8hours of SOT and I could achieve 3days like you just by using WiFi, I use LTE because it's faster were I live but remember that there are people so disappointed with their phones because they want to get the most out of their phones and just can't, may I ask if you are amazed with your battery life or do you own other device that beats the s7 on battery ?

I am amazed, it's as good as, if not better than my previous phone the z3, which was running a custom rom and kernel.
I do consider myself lucky to have the phone run so well right out the box.
Also when I said alot r fu#&ng around with their device, I meant roughly the same as you, I didn't mean to imply their problems r not actually there. I meant as u had said, changing roms, removing apps for new, disabling apps, not letting anything settle, wont give good results in battery life.

Holy smoke, 5+ hrs sot in half of battery. I've been trying to get more than 6 hrs for like a month now with different roms and optimizations, not even close..

I hate to be the voice of cynicism, but we do need to stop this stuff somewhere. The original post is utter nonsense. The suggestion that phones 'learn' your behaviour just simply isn’t how kernels work. There's a very small degree of 'learning' but power management is a very reactive process based on exactly what's happening. The only thing new apps change is what processes are running, and the kernel will instantly scale to do what it 'thinks' is right. Some managers will observe processes for a bit longer and react based on that - but we're talking hours at most, NOT days.
The only credit I'd give to this idea (which seems to be all over XDA for some reason) is that the first few days people use their new shiny phone a lot more than usual, and probably also more than they’d think. They also become far more aware of battery life and will even turn on the screen just to check battery life, which will obviously accumulate batery drain - so the bit about using your phone more is certainly true. But anything about Android being some sort of AI Neural Network app learning extraveganza that learns what you do over several days is (for the most (significant) part) wrong.

Think this is just descending into another battery thread and we have one here already

Worth rooting? Can it improve my battery life?

Hey guys! Been getting around 4h SOT as highest on my device, AOD turned off, 30-50 % brightness, fhd+ and dark theme.
Can get through the day but can't get a minute more than 4h sot which seems weird.
It's not that I think the battery life is absolute ****, I'm okay with it, the thing that sort of "bothers" me is that i see people getting like 6-10h SOT on like 2 days of charge which seems unbelievable to me.
Now on to the question,
is my utterly **** 4g signal preventing me from reaching 6-7 h SOT or is it just that I'm "unlucky" with the battery lottery.
Is it fair to expect a 6-7h SOT if i do decide to root and flash something like a notorious kernel and a rom?
Which I know will permanently void my warranty.
Or should I return the device and swap it out for either another s8+ or something like a g6?
I hope I don't seem too much of a brat ****face but I did lay out tons of cash for this phone, which other than the battery I am incredibly impressed by.
Thank you guys for keeping this forum running, it's been a lifesaver!

Just use your phone as much as you like stop thinking about battery life if it's really a problem get a powerbank. Me my self if I'm at work I use a lot of GPS as I need to travel and I have my screen turned of as I listen to Google maps rather look this will put me at around 3 to 4 hours of SOT or more sometimes depending how much I use the screen. But when I'm at home I use the phone non stop and I get around 5 -7 I always use full brightest all the time full res gaming sometimes youtube etc as you can see the people who get 6 to 10 they don't even use the phone that much so is there a point for them to have this phone if they don't use it to full potential no they might as well get a cheap phone.
Edit:
The only reason I would suggest rooting is if you want to play around with the phone like having a different kernel that allows to change voltage, speed etc

This, i can get 20hr sot on my mate 9 if i leave it with screen on, take in account SOT means NOTHING, it just one measure that can be easily manipulated.
I use my phone the way i use and i only judge by the end of the day, how much perfect left and what took the most of my battery life, without caring about SOT at all.
Just now i was traveling to Budapest and made ton of photos and videos with my DSLR and the Mate 9, on sunny days your brightness will be up, shooting 4K videos and taking pictures, using GPS google maps, will make your SOT low, does that mean your battery life is bad? NOT AT ALL
Stop caring about sot and use GSAM monitoring up to understand if there is a rogue app.

I have the S8+ and I see that they have figured out how to root the Snapdragon version. I am not really pressed to root my phone.
The 1st time I used the phone, which was a weekend and mostly WiFi, I got over 6 hours of screen time. However on my work days where I use mostly LTE service and I'm inside an office building, I may only have 3-4 hours of screen time but I will make it home with almost 50% of battery life.
I'm no longer concerned with screen time. If my phone can get me through a full day, then I'm happy with it.

Hey guys! Been getting around 4h SOT as highest on my device, AOD turned off, 30-50 % brightness, fhd+ and dark theme.
Can get through the day but can't get a minute more than 4h sot which seems weird.
It's not that I think the battery life is absolute ****, I'm okay with it, the thing that sort of "bothers" me is that i see people getting like 6-10h SOT on like 2 days of charge which seems unbelievable to me.
Now on to the question,
is my utterly **** 4g signal preventing me from reaching 6-7 h SOT or is it just that I'm "unlucky" with the battery lottery.
Is it fair to expect a 6-7h SOT if i do decide to root and flash something like a notorious kernel and a rom?
Which I know will permanently void my warranty.
Or should I return the device and swap it out for either another s8+ or something like a g6?
I hope I don't seem too much of a brat ****face but I did lay out tons of cash for this phone, which other than the battery I am incredibly impressed by.
Thank you guys for keeping this forum running, it's been a lifesaver!

Firstly,
I fully agree with @Derpling post above .( His last paragraph..)
Also SOT, now days, means nothing to me.!
Many years back, i used to be obsessed
with benchmark, battery usage, performance etc.
I also use to root all my device's.
However, presently i have stop been " obsessed"
and accept what is reasonable/acceptable.
eg. battery usage including SOT.
prefomance and stop rooting.
There is plenty work arounds available.
Presently, what i do
is i have a few good battery
apps... Betterbattery, Wakelock detector,
Gsam, I enabled these apps with ADB, to get them working. No root. (Very straightforward one or two liner commands, that's all.)
If i have a rogue app, and my battery use " suffers" i use these apps to id the app. and sort app out accordingly.
eg clear cache /data or uninstall.
Lastly i read online that presently,
more devs are
using " other alternatives" than root.
eg ADB...
to give you similar end results.
Bottom line... I found that in most cases
rooting a device just
creates other/more issues.!.. to fix.!
Now days, for me to root my device ( if ever again)
i must have a very, very good reason to root.
Good luck

You so right about root, there is a workaround to everything tbh, i use the Mate 9 without root and it's the closest phone in my opinion to perfection, no tweaks needed.
Geekbench SOT all of it are just numbers as it means nothing.

I think this is your problem, not the battery. One of the biggest battery killers on any device is a weak signal as the phone will push more power to the radio to try and find a better one (not exactly what happens, but there or thereabouts). Rotting won't change that.
Have you tried switching to 3G only, does that make a difference? Does it differ when you spend time in an area with a better signal?

The problem with my service signal is just temporary, I've been working for the summer but I'm moving back to the university tonight, there I have full 4g and 3g signal so hopefully this will change, however I have settled down a bit with the phone and I'm pretty happy with the battery now, 4h sot is not bad

yea rooting aint the solution
try gsam, wakelock detector, etc to detect the rogue app

imho you don't need root to improve your battery life, i'm achieving 5hr SOT easily with brightness 50%, AOD on and resolution WQHD+, all you need is to disable some of the preinstalled packages, do a bit of research to find out which ones can be disabled without a risk, then you will be good to go pm me if you need an assistance

I think your battery preformance is most likely to some apps or how you use it, I can say from expariance and experemanting with my S8+ that SOT and battery over all can shift.
I haven't rooted since im using samsung pay and haven't had a real need for root yet. but have tried a couple of diff apps and tests to max my battery but found that non off it really saves battery, quite the opposite.
I have tried substrantium to go all black in the phone (cus we have Amoled) but my battery life got worse
tried nova launcer to get some preformance boost and also black down the theme, but nova still suffers from battey drain issues (had same problem with my HTC10)
have disabled alot of services like bixby etc with BK Plugin. but made no big diff.
So after having the phone since launch and mixing and matching stuff to see if I could squeese a little more life out of an already good phone, I got to conclution that Samsung has done a good job in optimizing the S8+.
The stock launcher is fast and efficent, the built in "cleaning" program works well in shuting down unused apps etc. and running the phone with no extras and not tweking anything special or trying to get the phone as black as possible, I can go about 2 full days with normal use.

If you have the Snapdragon, battery life will decrease, by 20%.

I switched from a Verizon S8 to an unlocked S8+ and imo not having any of the added bloatware makes a difference. On my S8 I could make it through a whole day but my battery would be down under 10%. I know the S8 plus has a bigger battery but I go to bed with 30-40% of battery life.
I run my phone starting at 4:45am with a gym work out and I'm in bed by 11pm. My usage is mostly lte except for when I'm home. My SOT is always 5 hours or more.
