[Q] What to do Against battery drain?

I now have one week to the Nexus One bought secondhand. It suits me perfectly stand alone I have a little trouble with the battery life of the phone. Morning when the phone is 100% and I come out of school (14:30 hours) the battery is still around 20%. I find this a bit short. Ok, I'll use him at school (bit Internet, twitter refreshes every 9 minutes)
There is an automatic task killer, and that helps a bit but I think there are about 80% after 8 hours battery life is a bit much. Me internet is also constantly and I really like to keep.
The battery is probably not because I've got 2 batteries and they both give the same result.
Anyone have any idea what I can do?
I've been a bit inet searched but not really found anything. I did see somewhere a separate battery behind the phone, but I'm not waiting because that makes him a bit heavier and uglier.

10% per hour is pretty poor battery life. Are you running stock Android? 3rd party firmwares can give you much better battery life (the latest versions of CyanogenMod are using less than 1% per hour when fully idle).
But there are things you can check. Have you looked in Settings -> About phone -> Battery usage? If you are using Gingerbread and you look at the graph, if there is a solid line (or mostly solid) next to the "awake" portion, it means that your phone isn't properly entering its low powered state. Download spare parts from the market and check out partial wake usage under the battery history section of that app.

Please post your screen on time value from the battery menu so we can see how long your screen is on.

I would say to go and disable background data. Disabling this will definitely improve your battery life. Of course, you aren't going to get you twitter updates but aside from that, the battery life should improve.

While it is true that battery life would improve if Background Data was disabled (or limited via a program like Juice Defender), it doesn't take into account his actual problem. Unless it is a ton of apps constantly downloading that is keeping his battery usage in the toilet, this will only yield a slight improvement. I believe the cause is is an app (or apps) that prevent his phone from entering the low powered sleep state.
I don't know what stock Android gets from completely idle use (haven't run it since July last year), but a basic CyanogenMod install would sip between 1-2% per hour with the latest stable and the latest nightlies, some are reporting 1% every 2-3 hours when the phone is left alone (due to a fix that lets the microphones go into a deep sleep state).

Twitter refreshing every 9 minutes can not be helping, that said I doubt that's your entire issue but reducing the refresh rate should help quite a bit.

If you bought it used, it could be a bum battery. Not sure i know what apps work best to find out that info. Anybody?

The battery app in my sig is the only one that reads the chip inside your battery to tell if it's legit or not, what the battery age is, etc. Needs root to work though.

You can also get Battery Left from the Marketplace and when it gets calibrated it gives you a time until death number and some other features.

[Q] Cyanogenmod 7.1 Battery Life?

Hello all,
I have seen reports that because the source code for the captivate has not been fully released, some of the processes cannot be put to sleep when they are not being used, and therefore causes bad battery life. I am just about to flash CM 7.1 and am curious to know how the battery life is on the captivate.
All info is greatly appreciated!

LWt mw know what you find out! Just flashed it and my battery goes quicker than my bank account. Please let me know what I can do to help this I like the rom

Jaye,
This happens frequently when flashing a new ROM, you should try wiping the battery stats or giving the ROM a few days to calibrate with the battery.

You should try a custom kernel like glitch or Neo to see if that will help. I get awesome battery life in miui which is bases of cm7. I find that neo gives me the best battery life.

Also, some people must be getting solid battery life, or CM7 wouldn't be as popular as it is. Or is this a known thing with CM7?

Yeah that's pretty awful. Try doing a battery calibration to see if that helps. It should never go that quick (unless you're playing some serious games). I've never really had great battery life with cm7/miui I've had the best battery life with all the recent samsung gingerbread leaks. I think those are better than cm7. But that's my opinion.

I am in CM7.1 since Sunday. I had very awful battery in start. So I did battery calibration, manually. So I got very decent battery on wifi. But at work I use att data so again my battery life was horrible. But I am seeing improvement since I am using this app called green power to manage my data. Try that.

If you get good battery on WiFi but not with mobile data, try a different modem. Not only are some modems inherently better on battery, but if you find one that gives you a better signal you should see improvements in battery life as well.

Flashing the Glitch kernel seems to have improved my battery life.

Solid Battery Life w/ Stock Kernel
Hey Everyone,
Juts came to report that I have been getting great battery life using the stock kernel. I would say it is a little better than Serendipty VII Build 2 which I came from. Only issue, and this is something I know is inherently wrong with Cyanogenmod on the Captivate, when you fully charge the device, it only shows it is charged to 98%.
Other than that, all good!

Have you seen an improvement in this regards, I am having the same issues, the WiFi is draining my battery slower then my data is.
I have also done the battery calibration and it doesn't seem AS bad... still doesn't appear to be great though.

I am just coming back to this ROM after experiencing battery issues even though Glitch helped a little. I decided to try and tweak some more this go round.
I am experiencing much better results this time. Here are settings and other tweaks or modifications I have in place.
-sync is turned off
-using Launcher Pro with very few widgets (just 3GWatchdog and Power Control)
-auto brightness turn off manually adjust according to need
-gps, wifi, BT, and data turned off when not in use
-wifi notification and location detect off
-installed jk4 modem (may get better results with different modem depending on your area)
-installed Glitch v12 high leakage
-the biggest factor this time I think is UVing on the Freqs that are used while phone sleeps >>>>>100/200mhz (set for the lowest UV setting possible on these that do not result in a sleep death or reboot when phone is put to sleep)

Battery Life stinks and phone gets hot

My battery life is pretty terrible. Running stock, power saver, and Snapdragon battery guru. I have to charge the phone 2-3 times a day. I use in moderately to light through the day. At night, it will drain almost completely while I'm asleep. I had a Nexus 4 before and battery life was way better than this, same location, same apps, etc. I don't feel like I should need to turn data and wi-fi off to get more than 6 hours of virtually idle phone life from this device. Is this typical?
I find the phone is hot a lot too, when I am not even using it.

I downloaded it. Shut phone off and letting it charge, then going to see how fast it drains. To boot, its been on the charger for 2 hours and it has gone from 9% to 62%. Something must be wrong.

With stock my phone battery life sucked as well.that's why I rooted it and running a sense 5 Rom.. and it's so smooth I have my kernel UC to less than one gig speed and it still move fast without the overheat

Definitely not typical...
I'm fully stock and not rooted. If I dont touch my phone it can last over 24 hours with data on (noticed this one weekend when I was too busy to play with the phone).
I use the Battery Widget Reborn app and it says a "Fully charged battery usually lasts: 18 hours 8 minutes" for me.
Sounds like theres definitely some kind of app in the background thats draining your battery and making your phone hot.

This is pretty typical battery life for me with data always switched on on a rooted stock 4.2.2 rom and was also pretty much identical on an unrooted stock 4.1.2 rom.
The main thing that saves me a ton of battery life is disabling apps that I don't use. By far and away the Facebook app is a massive culprit for killing battery life.
I'm very interested to see the gsam results when you post them.

I did this procedure that HTC instructed me to do to reset the battery/charging system. I think it may have worked. No excessive heat and a drastic improvement in battery life. I've attached a screen shot of the gsam though. Just curious what you thought of the results

Well it's a definite improvement over the sort of battery life you were describing before. There are always ways of improving battery life but as has been said many times before it's all a case of where and how you use your phone that will be the main factor.

My battery life got really bad with 4.4.2

I've been running for about 10 hours now, usually my battery life is around 60-70% at this point, but I installed 4.4.2 yesterday.
I'm sitting at 31% with only 40 minutes of screen on time...
Hopefully we get a 4.4.3 soon to fix this.

Yep seems like it.

same here, after updating to 4.2.1 and even 4.2.2 my battery life is worse. I used to be able to go 2 days with out charging and now my battery is down to 68% with only 43% on screen time and 6 hours off charger and nothing has changed at all with my apps. and my device DOES go into deep sleep properly. I have no idea what the hell is draining battery, man stock 4.4 was freaking awesome on battery life for me

Agreed. Battery seems to drain quicker on 4.4.2 then 4.4.1.

Chaos kernel will resolve your battery issues.

I'm really not seeing much of a negitive difference; I'm at 10h 33m and have 47% with my normal use. Emails, 43 minutes chatting, surfing all through the day and sms.

Nothing wrong here. Seems even better for me

Part of it might be the increased vibration strength and speaker volume. More power is being used for every day tasks such as using buttons.
I've been noticing higher battery numbers for the Google keyboard since the update.

I've killed Google Now as it was destroying my battery after the 4.4.2 update... screen is still the biggest killer of my battery though...

I went back to Nova Launcher immediately... no constantly active Google Now listening.
I've got 52% at 13h 23min on battery.
That's the *only* thing I've done after updating to the 4.4.2 OTA. No root, no mods.
Edit: Oh yeah, and I've got Lux installed for brightness control. Screen's a little dimmer than usual overall because holy COW I don't need it so bright all the time. Screen is still the biggest battery eater.

I noticed more battery drain immediately after installing the first update and it's the same on the most recent one, 4.4 had incredible battery life.

Noticed same thing here. Same usage pattern and same apps as with 4.4 but battery life almost exactly 1/2 what it was. I'm hoping this will improve after a couple of charging cycles.

Root and stay stock or ROM?

I am new to the N6 world and I am not happy with the battery performance getting around 3.5 SOT and max of 12 hrs of overall battery usage. I am so tempted to root, CM12.1 and Franco kernel. But I am hearing bad battery results with CM12.1. I know everyone has different way of usage but if you can share your experience it will be great. I have three pus email accounts one is exchange, twitter, instagram, Google+ (manual sync), screen brightness is 10%, no adaptive brightness, no ambent display, no location, i use Google now, rarely play games, dropbox, Google drive, one drive, turned off all Google sync except for contacts, calendar... etc.

You can squeeze another hour of SOT with a custom ROM and kernel. I usually get 4 to 4.5. Everyone's phone is unique but benzo kernel gives me very good battery life regardless of the ROM it is used with. It is based off hells core kernel which many people agree is among the best.

Good luck!

A custom ROM with settings with by Kernel Adiutor (or Synapse,...) *may* help. There are so many factors, including use (which you've touched on), areas of travel/use (and therefore reception), baseband version,...
Regardless, your willingness and patience to experiment with different kernels (recommend hellscore/benzoCore or blu_spark as starting points) and ROMs are very helpful!

Has anyone tried CM12.1 it seems like a very clean interface?

Try the M3 stock. I don't think you'll be disappointed. The battery is what it is, you can get some improvements however I think most of them exist in how the device deep sleeps. JDX 3.01 (rom) is in the thread. Good luck.

All custom kernels.can be tweaked for battery life. The choice.of kernel is pretty much irrelevant, unless you can't be bothered to learn the tweaks
Also, ROMs.have very little influence on battery life unless it's bloated and poorly coded. Although in.not saying CM is either of those things, typically cm ROMs have been poorer on battery life than their aosp cousins.

My N6 - stock 5.1.1 - Franco Kernel.
For battery life I am using apps with a black background when possible.
No G-mail but K-9 Mail.
No wallpaper 'No wallpaper app'.
WiFi interval changed to 200 with build.prop editor.
Flashed Black Google Now launcher
(Needs Google.app updates uninstalled).
Disabled not used g-apps.
Disabled not used services.

Actually today I am bit surprised of how well the battery behaved. I got 4 hrs SOT, 3 hrs of talk time, listing to music.
Here is what I did and I believe that pumped up my battery performance.
1. Switched network to 3G.
2. No WiFi.
3. Wiped cache from boot recovery.
I will keep an eye on it but if that's the case then I will just stay stock until M is out.

Yes agree, I noticed that too (switching to 2G).
Probably the 4G network is to weak for indoor use, and maybe bad signal causes more battery.
Hope you don' t mind that I add another point.
4. Restrict app background data of all apps. (Settings - Data usage - < per app setting > )

I just flashed Android M P3 and it looks promising regarding battery life and I am like the added features. Highly recommend to check it out.
