[Q] How to increase battery life?

hey im a noob here so im sorry if this has been asked before but right now i upgraded my phone to ics and the battery life is horrible and im too cheap to get a battery extender so is there anything i can do to improve it or am i just going to have to deal with it?

Get your phone to 100% battery and then just play whatever you like until it completely dies. Then, plug it in to charge and dont touch it until it gets back up to 100%. That is supposed to increase the battery lasting time by 20%. It only works once...so dont do it 5 times hoping for results. This is supposed to be done when you first get the phone, but if its never been you've never done it, its worth the shot.

Let the ROM 'soak' in. It'll get better. You are probably busy messing with it figuring out all the features which is normal and makes the battery seem terrible. But overall it is pretty good.
And the post above is an old wives tale these days. It's funny to read people still recommending it.

Kinda, when you first flash with a factory reset, you don't have a battery stats file. This is another good reason to flash when your battery is 100% charged. When Senior Members here say "soak in", they are saying that the first boot all of the system apk (application packages) are cached to /cache. Doing too much while these apps are being cached screws up the statistics of the battery stats. If I really want good battery life, I totally wipe, and let the phone sit for 10-15 minutes. I leave usb plugged in till it's 100%, then pull the usb and use the phone until it totally dies.
By this time, the day is over and it needs to be charged anyways. I plug it into the charger before bed and let it charge up all the way with nothing running (no wifi, no bt, no background apps running).
After that charge, battery life seems soo much better. ymmv. it would be good to know if that works for you too.
Otherwise, everyone uses their phone differently, and some people install stupid apps that have intensive background services running that eat batteries, then complain about the rom sucking instead of introspecting about how they use their phone.

Just to clarify - battery stats file have nothing to do with battery performance and the battery stat file "is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point)." Google Engineer Dianne Hackborn

ahh ok thanks guys ill do what you guys said and see if it helps

you can also install one of the battery saver apps on the market, like juice defender or similar. They will typically help and some can control how often background services are allowed to collect data.

These arent as helpful as they use to be. I have seen and challenged people to run with and without and the added battery life is either very minimal or actually worse with these apps.
Battery saver apps where created when android was very young and had bad management of the battery power. The way it works now it should lower the power to the radios low enough to save battery but not completely shut off the radios. Shutting them off will actually harm battery life because it takes so much more power to turn them on and off repeatedly then to let them idle.

no i think it was more designed for froyo and gb because if you try those battery savers in froyo or gb you can see it works and battery last long but if you test it in ics or jb (i have test juice defender with jb in the sgs3) and what i can see its that sometimes it lags (not always just when you like two or three apps open which for me in the sgs3 was weird) and data sometimes hangs i mean it doesn't load pages

Download Gemini from the play store and manage the autorun for apps. That's what I do and it saves quite a bit of battery

Ill agree with you on froyo but gingerbread towards the end was much better.
The biggest thing is people dont realize how much power is used to start and stop things. Letting them idle will use battery but not nearly as much if you start and stop many times a day. Now at night if you want to turn off those things then yeah go for it. But if you are a frequent phone checker then starting and stopping them everytime will chew through the battery.
A good example is this, its summertime go outside and look at your electric meter when the ac first turns on. It will spin reeal fast for a minute or so while the system gets everything going then it will slow down. This same thing applies to your phone and its radios. Each time you shut it off it has to go through a process so you dont get corrupted data. And when you turn it on it has to use a lot of battery to make sure things dont get messed up and get to the proper operating form.
So any app that shuts off the radios manually and such will end up costing you battery if you are a power user.

If you can follow the steps exactly as i wrote them, then install the team FAH-Q kernel found in the dev section...

I put FAH-Q kernal on AOKP and it seemed to help a bit. I was using systempanel and it said facebook was sucking cpu at night while the phone was resting... so i took off facebook for the moment to see if any other apps/processes could be causing a drain.
side note:
I spend 15-20 min in the morning going through stuff on my phone. Then I will listen to music in the car on my way to work 35 min. My phone will be at 80% by the time i walk in to work. I check things during the work day once and a while and by 2pm I will be around 40%. leaving work I will have 35-30% .... ok i'll just quit now and say running 12hrs i will have about 15% left. I think I am an average phone user. not sure how much everyone else uses theirs.

Music soaks up a lot of battery as well as display, data, and sync. You can try turning off sync and data when you don't need them. But it sounds like you are doing better. I am still concerned with what else you have running in the background though... however, 12-16 hours isn't bad at all...

What do you mean by totally wipe? do you mean go into recovery to wipe data, cache, and davlik cache? then restore after the battery is fully charged?

Yes, as well as /system/ and at least .android_secure on your microSD
I would recommend against fully discharging your battery as a matter of course. While this might have been useful in the days of NiCads, deep discharges and heat are the Kryptonite of LiIon batteries.

it died on me for no apparent reason...

nearly was late for work because my phone died and i was using it as an alarm. what could have drained 50% battery in 6 hours and not show? wifi was off

while the graph is nice, better battery stats is what we need.

what you didnt post is the page with what was using your battery by %. now how are we supposed to tell you what happened and what used your battery? this thread is pointless because you gave us no usable information. what i got from the info that you did post is that a UFO flew by you and drained your battery of its power. and the thing is, my guess will be just as good as any other guess.

stock alarm app, no. but you do have a lot of wakelocks. when the screen is shown off, your device should be asleep. your device shows a lot of activity when your screens off(ironically, not when the supposed battery drain happened though, so i cant say thats why it drained).

Do you have the horrid camera bug?

Do you use exchange at all? I've had a lot of phones (android mostly htc and iphones) hit bugs from exchange in push mode and burn through their battery really quickly constantly trying to sync and hitting an error.
I charge mine on my dresser next to my head, and also use it as an alarm, I'd recommend charging it over night

I'm guessing this http://www.androidcentral.com/googl...cpu-usage-bug-fix-coming-next-android-release
I found it by googling "Nexus 5 horrid camera bug" lol, first link

Stock apps have no such issue as till date.Except for apps that use internet /wifi consume a lot of battery. So switch of those frst or keep ur cell on flight mode. The battery consumption may be due to gplay service, account sync,gmaps etc. I don't own a nexus device but I have experienced this kind of behaviour with my phone sometimes with a hot back cover sometimes.Try using apps like greenify to control this prob(or switch of ur network @ night/use lower cpu values + governers like powersave/conservative)

[Q] What is this thing that is eating my battery? com.android.systemui

Rooted -- Calkulin's Stock "Battery Saver" ROM -- Xposed Framework -- a few mods from XBlast Tools running.
First off, a Root Explorer search for com.android.systemui returned nothing.
What is com.android.systemui? I don't think I saw this in my usage until a couple of days ago.
Why does 31 seconds of CPU and 1 second of keep awake = almost TRIPLE the battery use of 12 minutes of screen-on time?????

It's the actual System User Interface. So most likely a combination of the rom and xposed are causing this. Also, dirty flashes of ROMs can cause this.
If you installed a new xposed module and noticed a battery drain the uninstall that module. Otherwise remove other xposed modules. You could always try a frew full wipe in recovery as well.
I have had this issue with mostly with dirty flashing which is my queue to do a clean flash. It's also possible if you restored any apps with data, like from Titanium Backup, could potentially cause this as well.

you got caught up in a lie, with buzzwords that are pushing for you to use the rom. theres no such thing as a battery saving rom. all those scripts/mods being used in the rom are just buzzwords. battery life is all dependent on how you personally use your device, how you set up your device, and your data/phone signal quality. a rom will not save you battery.

Thanks for the help, Tom. A visit to recovery to wipe caches and fix permissions and a reboot caused this -->
simms -- I do understand that. I am not really disappointed in my battery life -- and it doesn't seem to have changed much in the week that I've had the phone. But the reporting of it had, and that sort of alarmed me...

wow, your android system is high, even though only 10% battery was used. a reboot might fix that though. you might have to go through your settings and setup again, disable stuff like google location reporting/history(it wont disable your location).

I'm beginning to think the issue I'm having is in the reporting -- not actually a battery use problem. I've only had the phone a week, so my data base is small, but I haven't really seen bad battery life nor any real change in it. Even with some use and a bunch of time fiddling with the mods and stuff, I've yet to go to bed with less than 50% left. Mostly, more...
Here's the latest pics. com.android.systemui is back on top in the overview with 36% The detail page shows 39% and a whole 2 seconds of CPU. That just CAN'T be right...

Which battery graph? You mean the current usage graph I showed in the OP, from Battery Monitor Widget?
Re Bluetooth: I just leave it on, so when I step in the car it just connects to the car. No muss, no fuss, no bother.
I suppose I could try turning it off and see how much battery I save. I know with my previous phone (EVO4G) the point at which I started leaving the bluetooth on all the time didn't change my battery life to any noticeable extent.
Here's battery monitor widget current use. The EVO idled at 70 - 95 ma. This one does seem to draw a lot more at idle. I don't know what's "normal."

Not very interesting. It keeps resetting, every time I plug in to USB to transfer the screenshots to my mac for posting here. I'm not leaving it plugged in very long -- I just move the pics and unplug it. I unplugged it this morning at 7:30 AM. It's now almost seven hours later and I'm at 93%. That ain't bad. It's a gradual descent -- no big drops like the one in your post.

If your phone is vibrating a lot and you have extra UI elements installed this seems normal.
When you only use a small percentage of the full battery smaller drains appear large.
Bit off topic, but have you thought of using WiFi to move your files over? No messing with the wire and you could even automate the task.

Battery is very weird ?

Hey guys. I recently went back to 25r in an attempt to get better battery. And I am. What's strange is that in the first 50% I'll get 3hours soc. But I'm now on 18% with 4hours and 10 mins. Seems kinda strange. Not using the phone any differently. I do have a Google play services drain but its only 14% and I don't think its doing that much harm
Any one else?

Posts like this don't really help as we need to see what wakelocks are going on with your phone as well as the number of times its waking up your device.
The whole post-50% is a coincidence.

It's completely normal for you to have a 'faster' drain on the lower 50% of your battery life. But what Zephik said is right, it's impossible to say what's happening on your device without you providing some accompanying analytical data.

Im quiet happy with my battery, get about 3 hours soc until 50% and then i get home from work, so its not a massive issue for me. What i find weird is the 49%-1%
Drain a hell of a lot faster, not really an explanation as to why it does that?
Hoping the 38r update that comes out next sunday makes it even better though

Install a app such as GSam / Wakelock Detector / BetterBatteryStats, on your next battery cycle running one of the 3 apps listed, post up screenshots of the listings so we can further discuss this. Or you can take a look at them yourself if you know what to look for.
You'd be looking for partial wakelocks / wake ups

Battery saving apps

There are plenty of apps which supposedly save battery life majorly by real-time optimizations. The most popular seems to be Battery Doctor and Clean Master which also have very high ratings on Google Play. Does anybody use them? What's your experience on their battery impact? Do they really make any difference?

All I use is Greenify. It's an awesome app and a ton of people swear by it.

Honestly battery apps make it worse. Greenify is the exception.

I'm always running out of battery. I went dead in the first few hours today and then I used my Chromecast to watch the interview and was at 50% when I started. Screen off entire time 17% at the end. Now 15. Idk what to do about this drain. I've gotten lucky once with 4 hours screen on time though

Not sure why you'd expect good battery whilst casting. Its a massive battery drain, using wireless to send data. Especially large chunks over prolonged periods.

I'm not convinced that's accurate, but even if you're right, there is a constant connection between Chromecast and your device, with wakelocks and large data usage.

Run your phone until it's had a good run (80% battery used or something) and post as many gsam and android battery stats as possible in that thread. Use
tags so people dont have to load all pictures unless they want to. Make sure you go into teh battery graph in andoid and screenshot that and also into the big offenders, like screen so they can see how long things have ben running

Chromecast does not stream data from the phone unless its local media. If you want to see for yourself, stream a netflix movie and turn off your phone once it starts playing.
