[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.

battery consumption problem caused by bad voltage handling?

so I downloaded somekind of battery widget that have graphic log on the voltage and I noticed that when my new optimus 4x's voltage jumped between high and low it cause the battery to drop rapidly... CMIIW, I can't help but feeling that this is very much like those happened at contemporary desktop CPU that constantly adjusting voltages, however with the bad efficiency one, not sure if this is LG's fault or Nvidia's, anyone here have article reviewing/explaining the Tegra 3 platform? CMIIW, the CPU is Nvidia's right? or is it somebody else's CPU?
anyone else noticed similar behavior? any suggestion on improving the battery life?

When root will come out, definitely will improve battery

can you describe your meaning of a lot there? for me if I use this phone a lot, it will only last 8-10 hours! for constant gaming it maybe will only last 2-4 hours!

only the moto raz maxx will last longer then 4h constant gaming.
alot for me is about 10 calls, 20-30 messages, wifi,data and sync on at all times. navigate during work, check rss feeds and email a couple of times / hour. play wordfeud and rumble with notifications.
maybe im not as heavy user as others but thats alot for me and i dont feel any change in batterylife from my meizu mx or htc desire. u get 2150mah battery in this phone, compared to meizu mx or desire with their 1500-1600mah but u also have double the performance and alot bigger screen, why would it last longer?

LG states that some apps cause battery drain. I have read it in some internal b2b document from LG site. One of the apps mentioned was poweramp. Don't know if problem is fixed with newest firmwares.

I reduced the backlight and after the update it looks okay.

[Q] Will hard/factory resetting the phone improve battery life?

My initial standby time was around 5 days, and estimated battery time would be 3 or 2+ days..... now its only 1 day 7 hours and and standby is about 2.5 days... would hard resetting it help?

Yes, because all the apps which draining your battery will be gone
I'd search for the apps which are eating the battry first and disable them.

The times are calculated based on your usage. I even had 15 days once but then once i started using it properly it dropped. It's basically a good estimate of real life usage. Don't worry about it

Well... unless there is something wrong with your battery (due to a software bug or what ever). It really won't change. In the first few days your estimate will be high,
but like people above said, it's based on your usage. You really shouldn't look at the estimate at all. Like it says, it's an ESTIMATE.

BetterBatteryStats, GSAM, or even 3C toolbox has a great battery monitor. I'm afraid that on 4.4 you need to have root to use BBS & 3C, not sure about GSAM.

How I am getting good battery life: A simple guide with some links and stuff!

I see a lot of people complaining about battery life, myself included. I have tried just about every ROM there is and used all the battery saving apps and I think I've found a winning combination that will leave you with a fast phone and good screen on/off battery life. My stats so far today are 8 hours off the charger with 1 hr 30 mins SOT and still 80% battery left and that's shifting between my work WiFi which has many access points and causes WLAN_RX wakelocks and the crappy signal around this area.
I use the phone for general stuff like browsing the web, playing the odd 2D game whilst bored and push notifications from various social networking apps and I have been addicted to achieving 7+ hours of SOT over 2 days since I owned a Galaxy S1 many years ago. Instead of writing a crazy guide I'll just keep this thread simple and post my current configuration that is giving me good battery life:
- BOE2 bootloader, modem and ROM (I'm using Nameless ROM v2 for 910G)
- Roughly 25% brightness, all sync on, location @ GPS only (High Accuracy only when using Maps)
- Followed THIS GUIDE very closely which gives amazing deep sleep and still get notifications with the Push Notification Fixer app
- Uninstalled Facebook and Messenger and use Tinfoil with Pushbullet and the RSS Feed and set to open Tinfoil when I get a notification: Here's how to do that
- Discharge fully to 0% and then turn on again to make sure fully dead, then charge to 100% to calibrate battery
Wallah! You should get good battery life now provided you use the phone for the same things I do. It's that easy!

You need to be rooted for most of that thread don't you? I need my banking app from time to time so I can't root. Gutted!
Joe

Thank you for taking the time to write this up, but you should mention in the thread title that you need to be rooted. Thanks anyways though. I'm not the type to root. If Samsung can't deliver a good product for the $800 device they made, the device should be returned (which will be my case if the 5.1.1 update doesn't come in July or it doesn't fix the issues I'm having with this device).

Fully discharging a Li-Ion battery is not healthy for the long term life of the battery.
When will the myth of "re-calibrating" a battery finally die?!?
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
Similar to a mechanical device that wears out faster with heavy use, so also does the depth of discharge (DoD) determine the cycle count. The shorter the discharge (low DoD), the longer the battery will last. If at all possible, avoid full discharges and charge the battery more often between uses. Partial discharge on Li-ion is fine. There is no memory and the battery does not need periodic full discharge cycles to prolong life.

Smartphone batteries haven't needed to be calibrated in years. The only time you ever had to "calibrate" your battery was when your phone would sit at either 5% or 1% for hours before dying.
Even then you were calibrating your phones interpretation of the battery voltage levels, not the battery itself. Unless I'm very much mistaken battery charging is handled by integrated hardware, not software.
As a software bug overcharging a Li-Po is dangerous and completely avoidable

Most of the software needed on those guide required exposed.. My question is does amplify, greenify boost, and powernap works on touchwiz lollipop? Also does the current xposed works stably for now?

I have no battery issues. Got 2 x 4500mah from chima as well.

Huh? Never had a problem running official apps from two different banks.

I'm finding TW to be slightly better on battery under my circumstances - which consist of terrible signal fluctuation and rx_wlan wakelocks due to so many wireless arrays at work - however I will probably go back to CM12.1 soon or wait for Android M developer preview to be ported to Note 4 (fingers crossed) as I just love how stock and minimalistic everything is on stock droid CM and AOSP and it seems to be a lot snappier when combined with L-Speed mod.

They fit with the original note cover. And they last a bit longer then original battery.

I bought 1 as well & I get about 3 more hours. .... with the same use as with the original battery !!!!! Definitely worth it, ,, even if its only 3 hours

Sot (for who has bad one)

Hi guys
I'm not discovering the fire but I want to make a little contribution for those who has bad sot (I was really annoying for me because I can understand the upsets users ones), this was my discoveries:
The first one and most important:
It seems that the phone is programmed for a certain time of use, I mean it has a maximum time for sot: 6 - 9 hrs so you have to use that time to spend it on screen time because the phone also uses the battery for other stuffs. So if you pretend to get 6 hours or more in more than 1 day you will become mad and taking the phone and throwing it throw the window.
The second one:
Continuing with the last point doesn't matter if you try to save battery reducing resolution or stuffs like that. I use every day performance mode at max resolution and sound quality. The important thing is manage very well the brightness so disable the 10%extra from performance mode. Actually I could reach 6 hours at 1% with a intensive use with wify, data, gps and stuff like that.
The third one:
It is unuseful try to disable things and apps from the phone, they are not important on battery usage except for brightness and (at least for me) AOD. This one drains my battery and I really don't know what to do with this so it is disabled for me.
And the fourth and last one:
It seems that the battery needs a intensive usage in order to get it max potential. Some days ago I use the phone heavily charging it with the dex dock and using the interface and I noticed before that the battery expand it life.
Well, I'm testing if a dark theme is useful or not in order to get better sot but mean while I'm pretty happy with the battery life (40 days of usage); at beginning was very upset with this.
Hope to be useful for anyone.
Cheers and my best regards and thankfulness for the help of the community.

Thanks man

What's this 10% extra thing you are referring to?
My wife's default Note 8 gets approximately 5.5 hours SOT mine 6.5 to 8.5 SOT. She uses Facebook and the trash associated with it l and light themes. I don't,.also location on mine is gps only.

I advised her, but she doesn't care about getting more sot. That's all she uses the phone for I think, Facebook and Candy crush. Both of which are rubbish.
