Battery life - Nexus One Q&A, Help & Troubleshooting

Before anyone flames me or tells me that there are other topics let me say that nothing I do really works for me.
Anyways I'm using CM6 and 800mv kernel 2. 6. 35. In about 7hs of idle and 1hr using music and browser it drops to 64% would that be considered bad?
I use setCPU to limit the CPU when its screen is off. I turned off autosync. using launcherpro. What else can I do to make the battery life better?
Thanks

Try a program called Green Power. It's kind of like juice defender, but so far it hasn't killed my 3g apn

may I ask what you're settings are?

I just used all the stock settings, I don't think I changed anything.
Other than that, two other things I'd try:
1) Shutupbatterysaver. It's in the apps section. It's relatively new, but the dev is adding a bunch of new features. This turns off your apn when your reception falls below a certain db threshold. I tend to lose the most battery when I'm in areas with crappy reception. I just haven't really tried it in conjunction with green power, hopefully they'll play nice together.
2) find the battery thread in this forum and calibrate your battery using htc's charging method.

Which ROM has the best battery life?

Curious to know what the major consensus is as far as which ROM carries 1st place for battery life. In my experience thus far, Liberty is an insane battery hog (albeit an amazing ROM), and ICS is a bit below stock battery levels. Which ROM would you say has the best/longest battery life?
Steel droid is the best IMO but ive been on liberty 3 and its been average. Im not impressed but im not disappointed either. Anyways i flashed the v7 speedy script and that really sped up my phone and i noticed a HUGE increase in battery life.

on top of whatever ROM you decide to use. if you want to save some more battery life get juice defender and rom Toolbox. they have great tweaks to help out

Ohh yeah that too ;p I have that but i have it on the default setting. If u have a custom setting on can u tell me what urs is set at for optimum performance? Thanks man
Sent from my droid 3 using Tapatalk
honestly it depends what im doing. If im not going to be needing my data i toggle the button that turns off data when screen is locked. Other than that i use the regular settings for juice defender... for ROM Toolbox my settings are;
build.prop
VM Heap 88m
Scan Interval 150
Max Events 120
thats all i really did as far as performance/battery balance. i dont know what the values in some of the sections do so i left them alone. most imporant is scan interval though so that wifi doesnt kill your power. also i found out display is the primary power sucker for my system. So i keep that on low by default. Other people probably have even better tips but thats mine =]

Wouldn't reducing scan interval from 300 to 150 make the wifi scan more and actually decrease battery life? (could be mistaken)
my scan interval was set to 60 when i first got ROM Toolbox lol. But yea you can put it at 300, thatll save more battery life.
Oh default for liberty was 180.. i must have bumped it up and not noticed lol, wish I could set it to manual instead.
Well every fice minutes isnt bad. And juice defnder has a setting to only turn on wifi when your in areas you normally use it so that saves alot without havin to remember to turn it off

What is your obsession with controlling Facebook? Serious question, because I've seen a few responses from you talking about using Autokiller (a horrible idea to begin with) strictly for Facebook. You make it sound like Facebook sucks up 100% of your battery in an hour. I have Facebook running in the background all day every day, no joke. It doesn't even PECK my battery according to my stats. I think there's something weird happening on your phone.

I've noticed in some other threads him recommending autokillers/task killers. I don't know what others are doing with their phones but I always have 150-200 megs of free ram. You'll use more cpu time killing and having the app restart then just letting the app sit in RAM. If you find its operation that undesireable on your phone, just get rid of the app.
Another way to control your free ram is using minfrees. I'm set to have 100 megs free ram. If a particular app is runing wild you can kill it in settings>applications>running services, or just reboot your phone every now and again to clean the slate.
I know, off topic.
OP I find most of the roms are pretty similar in regards to battery life. I personally prefer liberty rom, I easily get 12-18 hours out of the battery and I use it a fair bit, often checking twitter, xda and other random surfing, frequent texts a few phone calls and a couple hours of music. I have gotten 40 hours with 25% left on the battery, with minimal use(face first on the couch after new years for 2 days) liberty throws up the high cell standby in battery usage but I don't believe it, I think its a reporting error. Other roms have had the same battery life without the high cell standby. I've found an apparent way to fix it(apparently) although its giving me some issues. Anyways, long story short, any rom should give you an improvment over stock with liberty and steel droid being the favourites

I don't know why but it kills my battery life and I am dead by like 5. It is just a suggestion take it or leave it.

I use DarkDroid and I get a solid 19+ hours of moderate/heavy use. I also use an 1800mAH extended, a little less than the Motorola 1930, but it works. This is the only ROM that I've NEVER had a problem with.
Also, if you don't like web based Apps like FB running in the background, try using the mobile web site and see how your battery life improves. Sounds lame, but it's better than keeping it syncing all day.
Personally, I'm still on stock and I don't mind. I have too many opportunities to charge throughout the day. I am eager to use CM9, but that's the only ROM I'll switch to. I have edited my build.prop to only scan wifi at 300, so that probably helps.
OP, I'd suggest using Tasker to help keep certain radios off at times when you don't need them. I have a profile which can turn off mobile data while I'm connected to wifi (at home I have poor data signal, which strains the battery by always looking for a different tower). Also, you can set up profiles to turn off wifi when not in a preferred cell tower range. So, if you are connected on your home tower, it will automatically scan wifi, then turn it off when you leave. It uses your regular phone signal, so wifi can stay off when you're not at work, school, home, friends house, etc. This is a bit more complicated to set up, but Tasker has many profiles ready for download on their wiki, which you can access from within the app. It's a paid app, but definitely worth it.
Also, you can have screen brightness turn up or down based on cell tower, or other conditions, to help in that regard.
Good luck and enjoy!

I prefer the mobile website fb to the app as i don't use it much.
Also juice defender paid version will do all you described, and probably easier to setup

Getting the most out of your battery

Ok going to try and start a conversation here to get feedback from everyone on what you guys do to get the most out of your battery. I see alot of people always asking what kernal is best for battery life and some people seem to have horrible battery life and some have exceptional battery life. I personally get decent battery life. Nothing super amazing but that comes down to the way I use my phone.
My current battery I'm using - Andida 2000mah battery
http://www.ebay.ca/itm/280843217453...X:IT&_trksid=p3984.m1497.l2649#ht_4497wt_1396
I also have - GTMax 3500mah battery
http://www.amazon.ca/GTMax-Extended-Battery-3500mAh-Microfiber/dp/B006VAP102/ref=pd_rhf_se_p_t_4
The Andida gives me generally a extra 2-3 hours more over the stock. I had to cycle the battery 4 times before I started seeing any real improvements. If I take these off the charger at 6:30am I can ussually make it to around 10pm without needing to charge.
The GTMax get me through a day (630am - midnight) with around 50% left.
Now keep in mind this is based on my usage habits, and when I'm at work my signal is horrible so it drains a bit harder for the 8 hours I'm at work.
I don't have LTE where I live or work, I do get LTE in areas close by but on a regular day I don't see it. With the bad signal at work I've started to switch to gsm only mode (phone was constantly switching from Edge to 3g/4g and wouldn't provide a stable connection most of the time). This seems to have helped my battery at work.
When I flash a new rom I always give it at least 2 good full battery cycles before judging the battery life on it.
Ok onto some apps. My first foray into getting better battery life started with wanting to control my data. I used Juice Defender to that but I found that having to wait for the data to turn back on was at some times taking way to long and even sometimes I would have to reboot to get it back. Tried a few others and had similar experiences. When it works its nice and I did see some gain from it but at the same time it seemed bloated and slow and I decided I like having my data on and readily available quickly. After some searching I found an awesome app...
Better Battery Stats
Play Store link - https://play.google.com/store/apps/details?id=com.asksven.betterbatterystats&hl=en
XDA Forum link - http://forum.xda-developers.com/showthread.php?t=1179809
I highly recommend reading up on this app and trying it out. If your seeing a big drain on you battery while the screen is off, it's probably because there is something that is keeping it from going into a deep sleep mode. This won't save you any battery just by installing it but with a little work it can make a pretty good difference.
Ok now this is where I'm looking for suggestions, are there apps that you find specifically run smoother or are lighter than their stock counterparts or rival apps that put less of a strain on the battery?
Instead of the stock messaging app I run Pansi SMS. It gives me a few extra options but I never really used the stock mms on ICS so I can only compare it to Handcent SMS and I think it is definitely lighter and a lil bit more battery friendly. It's not a huge difference but I try and squeeze everything I can w/o giving up functionality.
For a launcher I'm running apex right now, but for a lightweight launcher I'd recommend FTL. Runs really nice and smooth, nothing fancy about it, just fast and light.
Some apps sometimes can just be poorly coded and thus have a bad effect on battery life. Alot of people seem to feel the Facebook app is one such app that suffers from that. The app that gets the most recommendations as a replacement and being a bit easier on the battery is Friendcaster. I tend to agree with that, and would recommend trying it out.
I'd really like to hear about what everyone else does to try and squeeze out the most of their battery. Theres more stuff that I do, such as reducing the amount of things that are synced to only the stuff I actually want, default settings just sync everything and I don't feel I need to sync my contacts on a daily basis as I rarely change them around. So share your tips, experiences good and bad with apps in regards to your battery, and if theres enough feedback I'll try and re-organize this into a bit better structure.

Right here, this is the key. I have data off all the time. I only turn it on when I need to look something up or browse. IMO auto updates really kill the battery and aren't worth leaving your data on all the time. I'm on wifi a lot as well. Currently I'm on DarkRaider and I'm ending the day with around 30-40%, great improvement over stock.
It seems that with every new handset that comes out this is one of the hottest topics but the parameters all always the same with regard to battery life.
The 3 biggest things that drain our batteries are Display Usage, Data Connection & Radio Cell Connection. These are listed in order of current used. Of the 3 we can have some control over the 1st 2. Lower screen brightness and disconnect data when not needed and use wifi when possible. While wifi does use a good amount of current it's not as much as mobile data. The last one, Radio Cell Connection, we have very little control over. It's also the reason we see people having great differences in battery life. The further the phone is from the tower it's connected to the more juice it needs to make a good connection. So other than leaving the phone in airplane mode or planning your life around where towers are, neither of which are very practical, there is not much we can do there.
To get the best all around life from Li-ion batteries do not fully discharge them very often and also don't keep them plugged in after they're fully charged. It's best to recharge them when they get down to 20-30% and unplug them after they're charged. They also don't need to be fully charged every time, they have no memory. If your on the go and can only leave it plugged in for a short period of time that's fine. Also if you have more than one battery and your not going to use the 2nd one for a while don't store it at full charge. drop it down to 50-60% before pulling it out.
I'll update this post when I get home tonight with more info and links. Hope it helps.

I always make sure my auto updates are off. WiFi isn't an option for me when I'm working. How do you manage your data connection? Do you manually turn it on and off or use an app? I never really tried manually turning the mobile data on/off, just found with apps like JD that it sometimes took way too long to establish a connection. I always shut off my wifi when I leave for work. I know with ICS the widget toggles for gps don't work, they take you to the settings to turn it off, is there one for mobile data?

With my 3500mah battery I don't really worry about turning anything off. That thing is great. Made a bumper case for it but I miss having a real case on it so I picked up the 2000mah andida battery so I could get a few more hours on some days. If someone ever made a real case for those big batteries i'd use it all the time.

Try 2x Battery from the store. It will shut off data as soon as the the phone sleeps, it reconnects at screen on after unlock almost instantly. It also allows you to white list apps, like Pandora. The free version only allows 1 app though.

The DarkRaider ROM I am using has a nice extended settings menu in the notification bar with a data toggle. I also have a nice widget from switchpro widgets where I can customize what kinds of things I want to be able to toggle from my homescreen. Currently I have data/wifi/vibrate-silent/gps. Doesn't take long at all when I toggle the data on/off, it's pretty much instant.

I use the 2X Battery app. When the phone goes to sleep, the app turns off the data radio. I can still get calls and text messages. I don't have a need for push notification of e-mail, etc., so this saves me some battery usage. Of course, if e-mail and other app notifications are important, this app will help only if you are willing to wait until you wake up the phone.
Here's what I do. I'm on the stock HTC battery.
I SetCPU screen off to 192/192 ondemand, in call to 810/192 ondemand, and regular use to 810/192 ondemand.
I listen to about 2 hours of music a day, have 3 GMail accounts on autosync, a Facebook account on hourly autosync and HTC Weather on hourly sync. Automatic brightness. Roughly 1.5 hours of cumulative web-browsing, no apps/games used.
I never use WiFi and I don't live in an LTE area.
I typically end the day (19-21 hours unplugged) with ~40% remaining.
Now I am not sure if living in area with LTE is a bless or curse....
I would unplug around 7am everyday, and by the time I get home (around 6pm) I would always in red mode (meaning, it is either 14% or under). Using the Holics-0.6 with the kernel that came with it, battery seems to die fast. Even when I am on the stock ICS before this, seems LTE would just bleed this baby to death....
Reading other comments, might as well start looking for a bigger battery....
It actually seems like I'm getting better battery since LTE came to my town. I'm on dark raider using kozmick's rc1 kernel and it's even better now. Try turning off vibration feedback...I think it's located in the sounds menu in settings. You can also try using automatic brightness or even just setting it to stay at 50% or lower. The screen is a battery hog. There's a stickied thread somewhere on here that has other things you can try too.

Really is a shame that we have to disable or ease everything back so much to get through the day on a battery. Anyhow, I have a Velocity (which comes out of the box with the processor running at 1500) on Dark Raider. Therefore I use SetCPU to throttle the beast back, depending upon the circumstances. It only is allowed to run at 1500 when on charge and down to 400 when battery below 25 percent. I also use 2X Battery to take care of the netowrk and Wi-Fi and have purchased the andida battery for extended life. I also have JD installed, however it is rarely used - reason is that I am in agreeance with "citsong" that it takes too long to establish connections, even causing me general connection issues from time to time. So for around $25 AUD you can get through the day on a battery with moderate use and reasonable performance. I have not tried the extended battery pack, though I will probably get one of those as well...not sure which are the best???
I personally don't like the vibrate response thing, so I turn that off right out of the box, also, auto brightness is another that I set. When I go in the battery tab to see what is bleeding it to death, and most of it would be the display....
Though, vivid seem to have a smaller battery compared to other phones of similar functions and/or size, so that might be the reason I am not really seeing a very good battery life?

My solution was to get a larger battery (2100mAh, the largest one with stock format) and using juice defender to control my Data Connection. I am getting about 60% more using time on a normal usage whan before!
I actually have both Motorola Atrix 2 and HTC Vivid. However, my Atrix 2 would last about two days between charges, which is kind of weird. I have my personal account and company account on that phone (personal is to activate the google stuff), so it eats up data twice as fast, yet it is almost twice as long battery life.
And to update a little bit from my post before, it seems I am getting better battery life now, after 4-5 days of flashing the new ROM, let's hope it is true....or I am just going to go hunt for a bigger battery

Actually, the Samsung Galaxy Note is way bigger than either Atrix or Vivid, so with a bigger body, I would assume that a bigger battery is possible. But if you look at current phones, I rarely see batteries that are above, say, 1800mAh, let alone 2000mAh and above, stock of course.

Could you share the details on the battery?
Andida batteies are easily found on Ebay, but beware of Chinese fakes!! I got mine from a seller in Canada, all good.
I get good battery life by turning off data while I'm working . 70% with 8hrs unplugged

[Tutorial] Battery saving techniques

So yes this Phone's battery unfortuanatly is not well at all.. but here is how i managed mine to last a day without charging. Let me also say im a heavy user also. I text A LOT and always pull out my phone in class play a few games to pass the time or just browse my phone. So this does work for heavy / light users.
Go to Wifi/ menu / advanced and click never on Keep wifi on during sleep.
Go to settings/ Location access - Switch to off
For your brightness it will be on Auto switch that off and put it almost to the lowest as you dont really need it high just kills the battery.
- Go to the App store and download Easy Battery savor. When you access the app choose intiligent mode. It really helps !
-Dont ever use live wallpaper it just drains it so fast.
- DOwnload Faux App It really helps (Faux kernel Enhancement Project) Once downloaded go to CPU and set max clock to 1.35 instead of 1.5. it will still be buttery smooth and it will drain the battery less.
Also I am using the Franco Kernel - nightly #53 which in my opinion really helps !
- Try to turn off the WiFi usage as much as possible and you will see a huge difference.
That's all from me guys. By doing all this my battery significantly improved and lasts about a day now.
Anyways if you have better solutionson how you manage your battery and how you extend its life.
- post pictures
- post the apps you use
- post everything !
Thank you !
I use harsh. Whenever I don't game, I lower the max freq to just 810mhz, ondemand, row, mpdecision on (as harsh recommended) and it's still buttery smooth, and of course battery life is incredible, and I also do check the Disable HW Overlays and Force GPU in 2d rendering. And since no kernel controlling apps are needed, my phone feels cleaner too I can't upload battery stats yet as I'm in an area with only edge connectiom and I hate using slow internet connections

A couple of things I noticed with this. The first thing I notice is, in two of your screenshots, you appear to have mobile data disabled completely. The second thing I noticed is that your final screenshot shows 24hr 52 min on battery, yet according to your clock, a it should really be a total of 33hr 6 min since unplugged. Your first screenshot shows 88% battery remaining with it already having been unplugged for 7hr 35 min. With that screenshot showing a time of 3:11pm, that would mean your phone was unplugged at 7:36am. If the phone was unplugged at 7:36am, then how is it only showing a total of 24hr 52min at 4:42pm the next day? It should be showing 33hr 6min. That's an odd inconsistency there. All in all, even with the data that is showed in your screenshot, it shows very little use as phone idle and cell standby are both in your top 5. Your screen was your highest drain, yet there isn't anything else there accompanying it. I could be wrong, but it seems to me that all you did was keep the data turned off on your phone, and connect to wifi where available. You turned your screen on, but didn't really do anything with the phone besides having the screen just on. That said, even stock with no changes, a person can get 24 hours on a charge if they're disabling their phone and not using it.
Interesting tips however I have a few points:
Your first tip suggests having WiFi to Never stay connected during sleep. I am part of another Android forum which deals with tablets. We tested this feature as with a tablet, you are likely to leave it for hours on end before using it again. It was excellent if the tablet was not touched, however we noticed that it significantly increased the battery drain if you were regularly switching between sleep and using it.
Agree with the second but don't throw away practicality, use Location settings when they need to be use, not just turn them off and don't use them.
Leave it on auto-brightness dude, why ruin the nice visuals of a fantastic screen by having it so dark you can't see it? I only ever use lowest brightness when its dark or the battery is nearly dead.
No idea about the battery saver.
I definitely disagree with this. If you use 3G permanently, like I do, then turning on WiFi definitely reduces battery drain. I don't turn off data ever, so switching WiFi where possible is quite a useful battery saving technique.

His solution is to turn off connectivity and functionality on the phone. That defeats the purpose of even having the phone at all.
That said, I think a safe UC of maybe 200MHz can have a difference, but to me, it's all about enjoying the phone and the phone experience. No need to screw with it
Don't do the wifi feature. It will use more battery because it will constantly have to reconnect to the wifi connection every time your phone comes out of sleep mode and that will consume more battery.

Just curious, why did you buy it then? Personally, I'm leaving everything on because I bought the phone for the looks and usability.
And yes, the phone lasts me all day while using it for everything including emails, conference calls, web browsing etc.
I've set up profiles using the Smart Profiles app to quickly turn things on and off at will - hit CAR and bluetooth/GPS turn on, Wifi turns off. Hit HOME and the reverse happens, etc.

Same thing here..but I use scripts When I'm in school and all I need my phone for is some tethering and music, I activate my script that sets the max freq to just 810mhz and I undervolt an extra -50mv from the stock undervoltages of harsh, but when I'm out and away, I enjoy the full 1.5ghz quadcore beast trapped inside my pocket

Don't get me wrong, it's useful to have a decent battery life, but I really don't see the need to turn the device into an expensive brick. My suggestions, which may or may not be better than the ones in the OP, but they seem to work for me on every Android I've come across without screwing with undervolting etc:
1. Turn Auto-Sync off, or increase the duration between each sync. On my old phone, the phone would use Auto-Sync every hour or so which totally killed the battery over the course of day. I turned it off and would sync it manually (taking all of 15 seconds) on a Friday. Made a huge difference, although simply increasing the time between syncs is just as effective if not more so as you still save a bit of time (might opt for that myself :good
2. Use Inverted Apps on SAMOLED, Don't use Inverted Apps on IPS, white colour uses more battery on SAMOLED, but a lot less on IPS :fingers-crossed:
3. Get yourself a Toggle-based Notification bar, you will remember to switch off your WiFi when walking around in public. To that end, switch your WiFi off unless you are connected to a hotspot, the constant scanning will drain your battery and depending on the interval may take quite a large hit over the course of a day. If you rely on WiFi then maybe increase the scan interval time.
4. Turn off all mobile networking services when in a known signal blackspot. e.g. When work pays for us to go to a hotel on the Welsh border in Cheshire, there is absolutely no signal guaranteed unless you go to the end of the driveway, so I turn off all phone services unless I am there. Your phone will drink your battery very quickly otherwise, guaranteed. The easy solution is to use WhatsApp, switch your phone onto Airplane mode then turn on WiFi and connect to a hotspot (if they have one available, hotels usually do). This is surprisingly low on battery consumption.
So basically, just leave my phone in my pocket and not use it. Okay. Gotcha.

My battery life is amazing. I guess it just depends on what you compare it to. I had an evo 3d before, and my 3d would be dead by noon without even turning on the screen. My work blackberry lasts 5 days with fairly heavy email usage.
My N4 though, I use it fairly often for browsing, occasional calls throughout the day, streaming audio, this and that. After 12 hours of use I am still at 60% usually. From 7am to 5:30 (typically when i get out of work) I will be at 70%+
Not sure why people are so bent out of shape about it...
On my 3d if I ran facebook app or any stupid **** like that it would kill my battery like i didnt even have one.
Here's another idea get a job or pay attention in school. That will save battery life as well. I have literally seen people stare at a screen without doing anything with the phone, just because they are so obsessed with it being in their hand
Oh and my Sig does not represent the nexus in the mail

'How To Get Better Battery Life' tips and tricks

I haven't seen one of these threads yet, and I think it will benefit users of our D4 forum.
If you have any tips/tricks, feel free to add them here.
My first tip: TURN OFF 4G AT ANY TIME POSSIBLE. 4g is a battery vacuum.

Here's the biggest....Widgets and Social Networks.
Watch your widgets (weather, news, facebook, etc..) that update/refresh. Most will allow you to adjust the refresh time. Set it high or to manual refresh.
Social Networks.....set them to refresh only. You don't need them refreshing their data in the background, just have them pull the latest down when you are actually using them (Facebook, Twitter, Google +, etc..). Set to manual refresh so that they only refresh when you are using the app. You don't need the latest status messages your friends are posting hitting your phone when it's in your pocket.
WiFi and. 3G/4G.....if you are in a location that makes your phone drop/search for signal and WiFi is available....use WiFi. The constant searching/seeking and establishing a 3G/4G network connection will kill your battery faster than having a constant 4G connection. This leaves the cellular band free for calls and all your apps that sync/pull data from the internet can happily run over the WiFi connection instead of killing your battery.

I second this, keep your widgest, number of home screens, and social networking apps down. Phones haven't reached the point of being able to be computers quite yet. Here are some apps to keep it snappy though:
Fast Reboot (by Great Bytes Software)- same as a battery pull without having to. Clears up a lot of RAM.
Lte On/Off - with this, you can switch to 3G (CDMA) only, and have it set to automatically default to that setting in the case of you switching to airplane mode for some reason. But it does reset the app if you turn of your phone. Fast Reboot doesn't clash with this app.
App Cache Cleaner - clears out a lot of the cache you otherwise would have to go to Manage Applications to clean out.
That's all I can think of at the moment for non-rooted users. I won't go into rooted b/c this is not the right place. But here are a few battery saving settings:
GPS - have only the Google one on, it's the fastest in my experience.
Display - have it set to the lowest setting when at all possible. Only lowers color distortion in my experience.
Developer optionss - go in here and turn on the force GPU settings. This may not be the case with everyone, but it gives my phone a little more zip and makes things smoother.
Apps (this is the very bottom of the developer settings) - Adjust these to your liking. Perhaps try setting the max number of backgrounded processes to 4.
I wonder how it looks on you ...
on my droid 4 and with Jelly Bean i lost ~5,5% battery by hour no matter what i do even on airplane mode.. still aroud 5% by 1h
please can you advice how its look from your side ?

Making it better
The Droid 4 firmware just isn't very battery friendly... and it's not a new phone so your battery probably isn't either. Two things to consider.
LiIon batteries lose capacity over both cycles (cycling losses) and time (calendar losses.) If your battery is 18 months old and was charged nightly, you've lost 25% or more of the life anyhow... much more if the phone was kept plugged in after the charge and ran warm. And the drop accelerates with more cycles. It may be time to change the battery.
Adding JuiceDefender ( I use Ultimate) triples my battery life even in basic mode.
Replacing the battery is really simple; buy one from Amazon, open the back, carefully pry out the old one (it's held down by a double-sided tape), unscrew the connector (very small Torx, but jewelers screwdrivers work), swap and reassemble. $30 later (and a few hours to charge), you have your capacity back.

Turning off auto sync, turning off WiFi while on 4G works. Also make sure there's not any apps running in the background. Being root, there's apps you can download to close any open app

with CM it is an easy to safe much energy! and if you really want to do this on a right way, you really need to own a rooted system....
1. underclocked my cpu for 200mhz, dont have to comment.... if you use lightweight lounchers and care for background apps, it will noprob
2. use only 2g-networks, those are more available than every other networks, and even tcp/ip works with it, for whatsapp etc it is way enough bandwitch
very important!!!!
3. check your internal recievers after installing an app!! with "autorun manager" on a rooted device you can uncheck every function from every app, even autostart of an already killed facebook app, or statistical functions from apps which comes with most of them
4. get your brightness automated, if it is dark, you can automatically safe energy by a automatically regulation
5. maybe you would prefer to deactivate vibrations/haptic feedback/call vibration completely, its very energy consumpting.....
6. deactivate the gps-reciever complete, and just turn it on if you need it
7. set your display timeout as less than possible for your behaviour, 15 seconds may be enough
8. know what runs in background, evrything in background, sucks energy.....
9. deactivate nfc
10. deactivate bluetooth
with this i get a standby about ~1-3 days! and if im phoning and writing to much maybe not fully to one day. if i watch now on my energy tables, my display is consumpting still 40-60% battery per charge, but i dont think that even more safings would be possible
and with the app "tasker" you can even script this in endless environments

How does JuiceDefender save the battery? I have used many battery saver apps (including Juicedefender) and I always find that they run in the background and kill the apps which I would close anyway. Does it do anything besides kill background apps? By now I've deleted most background apps and have only kept the apps I want (which are few) and I still find battery life subpar.
Also definitely keeping 3G/4G off is a huge help. Wouldn't be able to make it very far without turning those off
I use Autorun Manager pro to freeze Google Play Services. Funnily enough, Play Store and Google Maps still work like a charm yet Google Play Services don't run background
Edited: With stock rom, install SetCPU and change the governor to hotplug. Underclock max frequency down to 800 MHz. You won't notice much different for normal tasks like watching videos, sms,...That setting is enough for me to play FF4 on MyBoy but playing heavy graphic games might not be snappy tho.
For me not using gaaps improve battery life. Every one knows for google play service that you cannot stop Instead I use calldav for my contacts.

5Ways to extend battery life of Nexus5

Here are five ways to extend the battery life of Nexus5. I know that many nexus5 users face the problem with battery life.
1. At first, turn off the auto brightness of your Nexus5. Cause it's the main reason for battery drain. Set your brightness always in medium or low.
2. 2nd step is, Turn off WiFi Scanning. You need to uncheck the "Scanning Always Available" option.
3. 3rd step is, Turn off your GPS location settings and Bluetooth. It draws a lot of battery power. Only use these when you need to use this features.
4. 4rth Step is, always use standard wallpaper, Any kind of animated wallpaper can be the reason for drain battery of your Nexus 5.
5. The final step is , Turn off automatic updates of Applications. But keep them up-to-date.
You forgot "Turn OFF Google Now if you don't use it"
That seems more like a general android guide than one specific to the N5... Just saying.
You forgot about custom kernals and under clocking GPU and CPU and undervolting
Sent from my Nexus 5 using Tapatalk
omg i would have never thought of this. you saved my life
Step 1. Install Franco kernel and tweak settings for battery (undervolt, reduce touch_boost)
Step 2. Install Xposed with GravityBox and tweak auto brightness settings
even though these ideas are a bit obvious to the experienced user, i thank the op for trying to help out
With gravity box I get massive battery drain, I know for many it's not an issue but I'm not alone in finding it drains significantly quicker. I still have the xposed framework but using the less feature rich wanam without issue.

Not true, usually what drains the battery is your apps misusing GPS or you enabled Location reporting. Location reporting really kills battery. As for Bluetooth, I have nothing to comment on that.
I will say as much as we perceive most of these to be common sense I learned a bit. Also I never have since I've owned android phones ever turned off GPS. It only uses it when it needs to. Such as browsing Facebook, maps etc. I also have Google now turned off so it shouldn't be pulling location data in the background now. I never use Bluetooth. My wife has it on all the time on her note 2 and she still gets the through the day with a good enough percentage.

Exactly. I have a charger at home next to my bed. I have one at work and a car charger. I'd rather be charging as I need then be pushing hard to get stats and be in a jam where I need to make an emergency call or my wife will be trying to call and my phone is dead. I might just be easy to please but as long as I can use my phone and still have some juice left before I go to bed I'm okay. I don't need it to last me without charge more than a day. I've owned a lot of different devices and never once complained about battery life or asked in any forum about battery life. Now I will say there are those people that can't or don't have access to chargers all the time and it can be an inconvenience to not have good battery life.

I have no such issues.
Install a custom launcher like nova launcher and delete the original launcher
Even if google now is turned off in the default launcher 1 accidental swipe to the left will turn on google now. Works for me anyway
i've done NONE of those things, yet my battery lasts about 28-30 hours...
battery savings has more to do with how you use your phone, and with what apps, than little tweaks to the core functionality of the Android OS.
