Any GN specific battery saving tips? - Samsung Galaxy Nexus

Hey guys,
I'm coming from a Droid X. Battery comparison is night and day. I have to constantly worry about my battery life. I hate this...
Has anyone discovered any problem apps that stay running in the background or constantly update that would cause the phone to drain the battery? I have watchdog and it doesn't really toss any red flags...
I keep brightness @ auto (as I feel I should). I rely on the OS to handle most of the app management. I trust that Google should have made the OS to handle itself...
Anyone have anything particular useful?
FYI -- I would consider myself a pretty intermediate android user.

Extended Battery Works on WP7

I've been testing the HD2 Extended Battery on WP7 for the whole day. After watching a few shows and one movie on Netflix, doing normal texting and web browsing, heavy amount of calling, the battery still has about 40% juice. The test started at 8am, and now posting 40% at 11:20.
Bring in Copy/Paste, turn-by-turn voice navigation and fix for camera focus (2-step button), this HD2 will be the holy grail of all phones. I have fallen in love with WP7 already. However, Android is kept on the second SD card for navigation.
My only problem is Android doesn't support the extended battery as far as I've seen thus far. Do you guys have a solution to that? I'd hate to carry extra battery around all the time. Although, I could just carry the extended battery for long journey.
How could android not be supporting it? It's not like it needs a driver. Sounds like Android is just chewing through the battery that fast. The battery isn't software dependent.

That's what I would think as well. However, none of the Android kernels have support for the extended battery. Some attempts were made, but to no avail. Apparently, improper reporting of CPU temp causes Android to shutdown in order to avoid damage.

[Q] Standby Battery Current Usage

I've looked through the other battery life thread, but I didn't see many people posting easily comparable data so I figured i'd see if my usage was normal compared to others.
I've recently noticed that my standby current (screen off, background data on) hovers consistently in the 50-60mA range. I'm using Battery Monitor Widget from the market to obtain the data. I don't remember if I had this with stock as the battery life was great so I didn't pay much attention.
I'm currently running Skyraider, but have had the same usage issue with AOSP roms (MIUI, CM7) and it doesn't seem to matter what's installed or whether or not the radios are turned on. Standby current never goes lower than about 50mA.
Anybody else using battery monitor widget or something similar care to post your average usage? Listing whether or not you're stock or rooted and what rom you are on would also be helpful.
Thanks.
I'm going to assume that no reply's means everyone is either happy with their battery life or nobody uses a current monitoring widget.
Just wondering why my Inc2 has a ~50mA standby current and a lot of other android phones seem to be able to keep that below 10mA. Some data from another user would help pinpoint if it's just my phone or the Inc2 in general.
My stanby by drain is also pretty high compared to other phones I've tried everything I could think of to track it down with no luck. Maybe its just the inc2

I guess it's good to know i'm not the only one. It's not that my battery life is horrible, it's just that it seems like it could be so much better if the standby drain was reduced.
I feel the same way. under battery use my idle percent was 1 on my inspire. on this phone i've seen it as high as ten. no screen off profiles or disabling widgets helps. I have no rogue apps either. it must be my phone

[Q] First timer - Pl suggest ROM upgrade to improve battery

Hello Champs.. I am first time user to this forum so pls excuse any idiot questions if it may seem.
I tried to go through threads to find answers but got completely confused, so though to put my question in simple words here.
I have Desire HD running task killer and Juice defender ultimate with extreme power saving option set and also optimized settings but still my phone don't last more than a day of normal usage. I just check emails, read news and call.. I do not play games and use any CPU intensive app. Phone is not rooted and running 2.3.5v of android
One of my friends told me after flashing ROM, battery power is improved by 40% in case of his tablet, so I am wondering if there is any suggestion for me to use for my Desire HD mobile. I have tried all options at application and settings level to improve the battery life.
As I am not too techincal in this field, if someone could write me few high level steps from start to end to get better battery life ROM and / or jellybean on Desire HD, I'll try to find out low level details of those steps in this forum and root (and flash) my mobile.
My sole requirement is to get as much battery as possible and if possible, some latest android version (4.1 or 4.2) to avail the new features.
Also, would there be an option to take the snapshot of current mobile setup in case if rooting / flashing goes wrong, I could revert back to the current version without loosing settings / data.
Thanks for your help.
two things, go to settings>about phone> battery
Or something like that. Take screenshots of your battery consumption, and the amount of time for each. Without that we can't know what's really causing your battery drain.
That said, a day of use will pretty much wind down your phone, the DHD has a very poor battery, decent sized screen, and most modern smartphones don't last terribly long anyways. However, you said you weren't using it too hard, so I'm not sure what it could be
As for juice defender, make sure that the intervals are set to no less than 15 minutes. 10 minutes pushing it. if you set it to 5 minutes, your phone will constantly be waking up from sleep (ultra battery saving mode), and constantly enabling and re-enabling radio. That'll cause more drain than it will save. At 15 you'll notice definitive increases, and at greater your battery will only get better.
Get rid of the task killer, or disable autotask killer and keep task killing to an absolute minimum. Never kill all your user apps at once. Kill only very large resource hogs (e.g. after playing a game, kill it). An autotask killer is very bad for your phone, and for your battery. Linux naturally tries to keep as many processes 'running' or cached in the background, using up a lot of your ram- it makes multitasking better, so in linux this is a good thing. With windows, it does the opposite, and if you run out of RAM you're screwed. A task killer will try to ruin that behavior, and in the end both performance and battery life will suck. It hurts battery life because after you kill that app, it'll just restart itself in the background- using more CPU therefore battery. Plus it also wakes your phone up from sleep when it needs it. I would only recommend a task killer for a phone with 512mb of RAM.
If it's an older battery, you could also have lost a lot of it's charge. I recommend installing battery monitor widget, and letting it run in the background. It'll estimate your mAH (battery capacity). If it's over 1,000, you're fine. If it's around 800, not bad, still doable. If it's at around 600, I would recommend going in for a replacement battery. I'm using an Anker 1500 (amazon), and I highly recommend it. Mugen 1600 is very good one, but it'll cost you a lot more money. I would not recommend an original HTC one.
finally, installing a custom ROM may or may not help battery life. With HTC Sense based ROMs, I've noticed a battery increase. In AOSP (unmodded, as google intended) gingerbread ROMs, you'll also notice a battery increase. With AOSP ICS, JB4.1.2 and 4.2.1 battery life is hit and miss, some ROMs will get you better battery, some will get you worse. You'll need to experiment around with it.
Also, yes you can backup everything after you install a custom recovery. I recommend looking up AAHK (advanced ace hack kit) on google and youtube, as well as rooting and S-OFF in general on youtube.
Thanks for your reply... Really appreciated. I'll look at the suggestions and see if it is unnecessary to root if 1 day battery is expected.
Do you think recommended high power battery actually improves usage time or people just compare their used up battery with new high capacity ones and think they hv got more juice in it. If high capacity ones really give another 2-3 hours of browsing as compared to OEM 1230 mah battery, I would rather buy it instead of flashing Rom.

[BATTERY] Significant Drop in Battery While Idle On Android 5.0 and 5.0.1

Hey All,
I'm just wondering if anybody else is experiencing this issue. Since upgrading to Lollipop, my Nexus 7 battery loses FAR MORE battery while idle than when I was on KitKat. I was hoping that 5.0.1 would fix this issue, but I seem to be having the same problem. It's entirely unacceptable that I go to sleep with 31% battery, and wake up with the tablet DEAD. I have kept a close eye on Running Applications, and have made sure to close them all before leaving the tablet alone. So much for Project Volta...
Anybody else having a similar experience?
Thanks,
Collin
I'm actually seeing the opposite. On Saturday I had mine plugged in and charged to 100%. I took it off the charger and threw it in my bag, where it sat for about 7-8 hours (drove about 3-4 hours and then it was in my car for a few at a restaurant before bringing it into the hotel), wifi and bluetooth on, but disconnected the entire time. It is in a Poetic smart flip cover so screen was off the entire time.
When I got into the hotel it was still at 100%. Used it for a bit that evening, and again the next day before driving home, and finally used it some more at home, but still had over 50% left before bed.
My battery life is also suspect.

I was one of the Android L developer preview early adopters and the only thing that kept me from switching back to cyanogenmod was the fact that on the last developer preview whenever Flo said the battery was low I was so surprised I felt cheated. The battery life was so good every time it gave me low battery life notification I was shocked because I had forgotten that this thing even has a battery and needs to be charged.
I don't know if this is psychosomatic or what, but it sure doesn't feel like this on 5.0 or 5.01.
Full disclosure: it's reporting 6h 22m of screen on time with 5 hours of battery life left to go, but it sure doesn't feel that way.
The battery settings used to tell me ridiculous things like 6 days of charge left. It doesn't do that anymore.
Right now I'm in the process of discharging it all the way to death. We'll see if that makes a difference.

Yes I'm having this issue. After upgrading via ota my tablet is dead in less than two days from battery drain

OTA, OTA with factory reset or img flashing?
Because if you upgrade yours N7 via OTA without factory reset that (and various others) bugs are possible.
My N7 doesnt show idle battery drain (img flashed) or any other bug, so far im very satisfied with 5.0/5.0.1 android.
First off don't close applications this is not Microsoft windows, second use CPUspy and a wakelock detector to see what is preventing your tablet from deep sleeping, third use a system disable app like auto run manager to disable any services necessary, fourth.....profit
^Agreed except for the last part.
Those apps that stop/freeze other apps like the one you mentioned, greenify, anything like that are all bull**** that cause more problems than they claim to fix, IMO.
Flash the factory image. Don't take the ota or keep data when its a major new release.
Battery life is awesome on 5.0.1 never been better.
Android 5.0.1
Default OTA 5.0.1 brings NFC active! When i turned it off, the battery became significantly more durable!
Just try it!

If you disable the 3 common service locks keeping the device from sleeping there have been no problems so far for me on n5 or n7
And yes greenify is worthless autorun manager not so much
^Yeah I see what you're saying. But still I don't like interfering with system apps, well like play services I mean. That can cause problems and battery drain. It really depends on how you use the tablet.
Edit: And obviously like said don't be closing running/cached apps. This isn't Windows 98.

Well I fixed it by flashing the unofficial cyanogen mod build for the Nexus 7. Battery life back to 4 days like I'm used to, and no idle drain.
Sent from my precious aka Nexus 7 using xda app. Any errors in the post are caused by auto correct and as such are Larry Page's fault, not mine.
I have the same issue something is keeping mine from sleeping cause its always warm. I used to get 5 days now I only get 3.

Wakelock WifiOffDelayIfNotUsed

Greetings
Battery life on this phone is actually quite good, especially compared to the nexus 5. I'm not sure it's having a massive negative effect but the wakelock WifiOffDelayIfNotUsed seems to be running for an unnecessary amount of time, and all gains to battery life are not unwanted. Searching both this site and Google seems to indicate this wakelock exists to sleep the WiFi connection after a certain time period. The fix was suggested to switch off this sleeper but I cannot find any such option in the menus for this phone. Anyone got any ideas?
Thanks.
+1
Bringing this up again. This wakelock is getting out of hand on my G4. It's been draining my battery like crazy.
Any fix?
