Battery life.

I havehorrible batter life and it takes forever for this phone to charge and it overheats. I'm using the andromeda kernal and OC widget. Can someone tell me some settings I should use? Or tweaks or whatever? I'm talking non-commonsense stuff (not stuff like "turn 4g off")

Turn on Airplane mode and leave it on. Tell people to call you on the house phone. Your battery life will improve dramatically.

The radio really sucks up tht much power, huh? :/ I wish sprint used simcards so I can have a reason to lug around my hero for when I'm out for more than 3 hours

Wow, 3 hours huh? I'm at least getting 8. I was getting 15 or 20 hours, but then started putting lots of widgets on my screens and that really killlllllllllled it

I usemy phone a lot. I was spoiled by my hero. I was getting days on a single charge with the same usage, if not, more. I wish I knew what's killing it so fast :/ spare prts says the screen is a majority of power consumption, but I usually have brightness on 0 (its plenty bright enough. It seems brighter than my hero at 50% ).

Is the Running time at 100%? If so, check Partial Wake Usage. Click on whatever's at the top of the list and check it's running time. Report back and let us know what you find.

Gps signal while berrert's low

Does anyone of you guys tried navigate with bettery lower than 15% ?
I couldnt, not even for a sec m, to get signal wirh low battery.
Did one of you came across this kind of behavior or is it just me ?
Maybe some kind of battery saving mechanism despite I didn't use any kind ...
What do you think ?

Battery Drains QUICKLY!

I got school at around 6 am. By the time I eat lunch it's already at 57%. By the time I get home around 5 and it's already at 17%.
All I do is listen to music (doubletwist/playerpro) and play Cut the Rope, WTF!?
Cell standy by is 46% in batter usage followed by wifi with 11%
any help guys?

What I tend to do is have brightness down to about half. Have you also tried fully charging the phone, taking the battery out and charging back to full? I sometimes find it drops down but regenerates itself.

Brightness is below half,I never go over. WiFi is on but not all the time.
Stock rom 2.3.4 rooted

Do you have data off?

How's your phone signal most of the time? It has been proven that low/bad signal drains battery quicker than good signal.
Sometimes certain buildings/rooms have pretty bad reception making it a huge drain for your phone.

This is a useful piece of information, however is not really practical. Ideally we don't want to be turning off our phones on every charge :/
I myself own 3 batteries, and alternate them (I have a wall charger for the batteries)

what ver are you using if 2.3.4 the battery issue is fix.

I get 3 /4 bars, at school right new and yea some times I get nothing, especial ly during the subway ruse which is an hour

Once I updated my phone to 2.3.3 I noticed that the battery life was sub-par, only lasting 3/5s of the day on a full charge.
I proceeded to root my phone (as I don't have the money to unlock my Big Red Bootloader); after installing SetCPU I took down the clocking meter 1 notch (768MHz) and the phone is stable with not difference in performance (so far). Doing this and removing some unneeded bloatware has increased my battery life 2.5x and I can go almost 3 days on a single charge.

xiEvo is correct and I've read a lot of good stuff regarding battery life with 2.3.4. I can only begin to imagine what kind of battery life I'll have once I get that update.

get juice defender off the market ultimate version is best. this will lookafter everything for you.. juice defender is a must have app for all android devices

I'm 2.3.4.
Honestly I had the best battery life with 2.3.2, IDK why.

Turn off BLN

So, like many other folks here, I'm also trying to find ways to improve my battery life. Overnight, even if phone is fully charged, with 0 usage, the battery drains rapidly, to 20% by early morning. Android System seems to be the one using the most battery (51%). CPU Spy shows only 15% Deep Sleep time. Since I get emails at night, the softkey lights stay lit all night. I'm thinking that's what keeps the phone from going into deep sleep.
Question is - how do I turn off BLN? I understand many people here love the nitification lights, but I honestly don't care much for this feature.
Here's my setup:
Android Version: ICS Passion 10.6
Baseband: T959UVKB5
Kernel: 3.0.15-ICUP ICS-Streamline #1
Build #IML74K
Juice Defender Ultimate
Wifi connectivity at home and work.

settings-display- uncheck pulse notification light...and yes this will prevent your phone from going into deep sleep!

Perfect
Thank you!!!

It uses power, and when the phone goes into deep sleep the pulse uses enough energy to wake the CPU doesn't it?

Bet it is the email that is preventing the deep sleep and the BLN is a cursory problem bc of that.

now could i do that with my setup? talon kernel on honeycream jw1 2.3.6. i hate the backlight and with it off i could probably get around 3-4 more hours of battery life

Pretty sure backlighting isn't the culprit since it is probably to lightest battery drainer there is. It is what I'd causing the BLN to light up that is draining the battery.

well yes but no. For example psx4droid. If you press on the screen the soft keys light up for no reason and stay lit which uses more battery... that's the only reason I want them disabled,that and I don't need to know when I get texts as I check at least every 20 minutes and each texts means a pulse.... not good.

BLN I don't think has ever had problems with not deep sleeping. I remember Eugene tested his kernel with and without BLN because he wanted to test battery life, hardly any change was noticeable. It's most likely an app that isn't letting the phone sleep.

Even the original creator of BLN has tested the code, and AT MOST it uses a total of 2% of your total battery with the lights on constantly. These are very low energy leds we're talking about here that use a minuscule amount of energy, not 4 hours worth of battery.
It's an app that keeps your phone from deep idle, not the bln.
If you realty want to test, set your phone on airplane mode over night and heck your deep sleep times, and even try it with bln on and then check in the btery to se if your phone reports sleeping (only in gb and above).

Alright thanks buddy I checked today at school and battery life is only affected by a small ammount when leds are on all day

I upgraded the battery to the Galaxy S2 version of 1850mah. I get around 75% after a night's sleep.

Anyone else noticing that the battery percentage goes down incredibly fast when screen is on ?

i've actually been pleasantly surprised at the battery life on mine! Over two hours of screen time midway through my day yesterday and i was just above 60%

Have been advised to turn cell broadcast off

My advice, get Tasker to disable mobile data and WiFi when screen is off. Disable Google Now. Disable NFC. Disable GPS until you actually use it. Enjoy your 5+ hour screen on battery life.

exactly my thinking.
Why the hell does the Nexus consume soooo much battery ? I have turned most of the stuff off but you dont get any Google Now, emails etc dont work correctly, - totally useless.
My S2 is better than this.

yeah its worse than my Galaxy S2. - battery stats say its the screen but that's on auto and its already dim as hell. When off it consumes power if WiFi is on.

And? Most people don't seem to get this: Say your battery depletes 1% for every 3 minutes you have the screen on, that's 300 minutes, or 5 hours, of screen time. Which is more than acceptable.

Yeah def better than the gnex which was rather good too. I took my phone off of charge @ 7:20am and put it on charge when it had 4% left @ 1:30am. So pretty much lasted 18 hours with medium use.

What do you mean cell broadcast? Where is that?

my N4 is 1% per minute screen on
2% streaming video, that right, 40 minute netflix = 80% battery gone
NFC and cell broadcast off, gps off, screen at 50% brightness

Like a fool i sold my iPhone 5 and got the nexus 4 only to be having this issue FML
