[Q] Which rom/kernel for battery life?

Hey,
This question has been asked a few times but with new roms comming out all the time I would like to ask again!
Currently I'm using baadnewz hd rom and the kernel that comes with it, using juice defended and setcpu, my phone will die by the time i go to sleep if it was at 100% when I wake up. This isn't good enough for me :/ I use my phone quite a bit.. Was looking for something a little better!

battery life
I use the latest stock rom with underclocking mod root and setcpu with some tweeks with sending around 200 texts 15 emails a couple tweets 1 hour talking and some doodle jump I get from six am to ten pm at 60% left.
What do you do on your phone playing games destroys battery life

I am on OpenDesire now, it seems a lot better. But still, I throw it on charge and in 1 hour it will charge 10%, but off charge it will drain 10% in 1 hour. It just seems so pathetic. People brag about 3 days battery life with their phones.

which eats up batt life more: games or surfing the net? I always thought it was the latter.
Also, what's the main difference between underclocking and undervolting? Won't underclocking mean a perpetually slower processing speed?

I can get two days before dying if I just email text and an hour of calling, but agian how do you use your phone what's eating up your battery?
And with set CPU I set it to 800mhz and when battery is below 35% I set it to 600
At 600 MHz I notice the browser it slower if I have more than one windows open
But the best is when I lock my phone the CPU scales down to 224mhz to 386mhz or something and that were I noticed the best battery advantage
games like angery birds destroys battery browsing is less consuming than calling.

[Q] Horrible Battery Life

How is everyone finding the battery life. Personally, I am finding it just plain horrible. I'm not sure what the issue is specifically but either something is draining it or it is just really that bad, in which case I will return it. I can't get a day's worth of moderate use out of it. It seems to be at most half of what I get from my note 10.1 and they aren't set up any differently. I've tried some of the basics like turning down the screen brightness (which annoys me), turning off the smart stay (but why have a feature you can't use), tweaking email checking settings, turning off samsung sync, turning off bluetooth (don't use it), and locations services. Is anyone else seeing this as an issue and does anyone have any additional suggestions for me to try?
Thanks in Advance

I get about two days between charges on mine. I get a decent amount of usage on a daily basis between email, Facebook, and candy crush. I even have Google Now running. How many charge cycles have you been through?

If by charge cycles you mean fully discharging the phone until it shuts off, I haven't done that, but could give it a shot. It has gone down to 10% several times though.

No battery problems here. I wouldn't blame charge cycles, if they have any effect at all, it is minor. If I were you, I would do a factory reset, followed by an exchange if the reset doesn't fix it.
I have smart stay on , backlight on auto, and take no extra precautions for battery savings.

Can you please post some screen shots of your battery life at the end of a typical cycle? It will help with comparisons by giving us more details on your running apps, screen-on display times, etc. Also, what wakelocks do you have? Use BetterBatteryStats or Wakelock Detector from the Play store for that. This info might help us to identify just how much drain is related to rogue apps or the general battery life itself.

Thanks. Just downloaded BetterBatteryStatus. I'll let it run for a bit and see what comes up. I'll post what I came up with with screen shots from it. Thanks for pointing me in a direction.

Also, it'd help to know how many hours "just plain horrible" is.
I'm not delighted by the battery life I'm seeing, I'm finding I want to charge every night, and that I can easily consume 15% / hour or more even without the screen turned up past 20-25%. (watching video off the NAS in the house.)
Then again, this is the first LCD display I've been able to read in full sunlight, and that's remarkable to me. I often wind up with full sun in the morning when I get up, and am delighted that if I did charge overnight I can use the device even then.

The battery needs some initial "training".
Charge fully on the first and run it all the way down to nearly zero, and fully charge again.
DO NOT interrupt the initial charge.

Battery life is great here after 5 cycles running it to 1% and recharging full at first it was draining faster but now I can watch 4 hours of netflix and still have 25% left nice thing is that the battery charges superfast so no worries

10% is just fine, for purposes of calibrating the battery meter. Preferable actually. You shouldn't actually drain the device until shutdown. There are safeguards that are supposed to ensure the battery voltage does not drop too low (its not actually zero when the phone shuts down). However, in reality these safeguards are not always failsafe and I've seen plenty of cases on various Android devices where letting the battery drain to shutoff renders the battery unable to take a charge (below the minimum threshold voltage). Sometimes, letting the battery charge overnight will bring the battery back. Otherwise, you are pretty screwed, as the only remedy would be a battery meter with a boost function.
In any case, the battery meter is not very accurate, even under the best of circumstances, so letting it drain to 10% is plenty accurate enough. Then let it charge to 100%, and let it sit at full for a while, as fully saturating the battery takes extra time.

That said, its hard to say what "moderate use" means. Everyone uses their devices differently. If you are playing intensive games, downloading files, heavy internet usage, it can drain the battery much faster than other activities. And the number of hours of screen-on time is key. So the idea of getting some battery stats and screenshots, is a good one.
I haven't been tracking screen-on time myself. But I find the battery to be decent. I use it a good amount in the evening (don't bring it to work) mostly for reading and web browsing. I have brightness on 40-50% usually (sometimes less, if the room is darker). The battery was just under 40% after 2 nights of use (maybe 40 hours after the last charge). Just guessing, but maybe 3 or 4 hours of screen on time?
Some online reviews mentioned the battery life is not as good as some other comparable devices (such as Nexus 7 and iPad Mini). Not surprising, since the Note 8 has a faster processor and higher resolution screen than either. And so far, battery life is not amazing, but seems comparable or better (better drain while idle) than my old HTC Flyer tablet. So for me, thats just fine.

I got about 4 hours screen-on time on my first battery cycle with heavy usage. Was playing games, movies, internet browsing, etc. My second and third cycles were better, giving me 5-6 hours screen-on time with moderate to heavy usage. Didn't really play any movies, but did play a fair amount of games and stuff.
On those later cycles my screen-on drain represented about 85% of my overall drain. This leads me to say that you can expect 4.5-6.5 hours of screen-on time with the Note 8, depending on usage. Keep in mind that I keep wifi always on, disabled bluetooth/auto-sync/smart stay, stopped some running apps like Maps and Factory Test, and kept brightness down to about 15% of the max setting.
Screen is definitely the big drain here, and these results lead me to believe that even with root and apps like Greenify I would not get much better results. Looks like any further battery savings will need to come from a custom kernel and custom rom (unless maybe you root and then underclock/undervolt using a third party app like Voltage Control or SetCpu). Anyone else have similar (or different ) results?

Although the battery life is of concern to me, the fact it charges via a micro USB input rather than propriatry cable alieviates that worry (looking at you Apple). I dont think I go anywhere where there isnt a charger available thanks to the amount of devices that use them.

While his terminology might have been a bit clumsy, he is not completely incorrect.
The terminology of "training the battery" invokes the concepts of conditioning the old technology NiCad batteries to prevent memory effects, which are not a concern with Li ion batteries, which is what you seem to be referring to. Folks on XDA will often talk about conditioning or calibrating the battery, which can be a bit misleading (as often they have the behavior of the old NiCad batteries in mind when saying this).
However, it is true that the battery meter needs to be calibrated to be completely accurate. This calibration has no chemical effect on the battery itself (like it does with NiCad batteries) but simply effects how the current readings are displayed by the % battery meter on the device's screen. Without fully charging and draining the device, it doesn't have fully accurate "flags" associated the current to battery %.
http://batteryuniversity.com/learn/article/battery_calibration
Failure to calibrate the meter won't have a negative chemical effect, like failure to periodically condition a NiCad battery. And therefore it won't have an affect on the battery life. But properly calibrating will give you the most accurate % battery reading possible. The battery meter is not accurate out of the box, after a ROM flash, and an OTA may also reset the calibration.
As I've already mentioned in a previous response, I don't recommend draining the battery to shutoff. As doing so can lead to the battery no longer taking a charge, and the device no longer powering on. Its rare, but it does happen. Fully changing, then draining to 10% or so is enough. Full cycles are also not good for the long term life of the battery, although just doing it once every few months is still acceptable.

Pretty good link, thanks. And reinforces what I just said above.
Most any smartphone or tablet made in the past several years uses a Li ion battery. This confirms it: http://www.gsmarena.com/samsung_galaxy_note_8_0_n5100-5252.php

The charger for the Note 8 is 2 Amps, while most MicroUSB chargers (at least for phones and other small devices) are 1 Amp. Although this varies, and there are other tablet chargers that are also 2 Amps; but these are far less common than phone charges that just about anyone with a phone that isn't Apple will have.
What this means is that the 1 Amp charger will charge the Note 8 very slowly. I tried mine on a 1 Amp charger just once so far. Left it on for maybe an hour, and the charge only increased by a few percent.
So yes, you can charge with most MicroUSB chargers in a pinch. But it will be slow.

Don't get the physical plug of a charger confuse you - I believe this tablet needs a 2amp output from the charger, meaning just because your charger has the same end connection, it won't necessarily help you charge this battery. I've had my users come to me thinking their devices are defective because they somehow started charging their tablet with their Bluetooth headset charger.
Someone also mentioned the black wallpaper that might help with the battery consumption - I believe that is only helpful on AMOLED screens that Samsung has used on other devices.
I'm really still on the fence on keeping it after I bought this - I'm coming from a GT 7.7 which had excellent build quality,screen, and battery life. The loss of the AMOLED screen for both graphics and battery efficiency is bothering me. I put both up side by side and feel disappointed that Samsung couldn't just make a JB updated 7.7 with new CPU, 2GB RAM, and stylus with the same design and beautiful Super AMOLED Plus screen. It's not even the price - but just feeling like I'm getting a somewhat inferior device (in a few but important aspects) from the 7.7, when it's supposed to be an upgrade to the older device.
I've seen the news about an upgrade to the 7.7 possibly coming, but will it come with the stylus that is also important to me and the other software enhancements from the Note 8?

Funny thing happened on mine.
The battery was VERY BAD the second day, but it could play live streaming for two hours when the battery was 1%. As soon as the tablet went off due to depleted battery, I charged it until it went all the way until the "full battery" came up.
After that, the battery is much better now, so don't say anything "dumb" or any nonsense because it works.

That is correct, having a black background does not effect battery life on LCD screens.
On AMOLED screens, black pixels are actually not emitting light (while pixels displaying other colors emit light), which is why a black background will cause less battery drain than other colors.
On an LCD, the liquid crystal layer that depicts the colors is not itself a source of light. Its lit from the back, and the light intensity of the backlight is the same regardless of what color is being displayed. How much light is blocked or let though by the liquid crystal layer varies depending on their alignment (what color is being displayed). But this doesn't affect how bright the backlight is, anymore than pulling a window blind makes the sun burn less hydrogen.

Gaming Battery Life

http://www.engadget.com/2013/07/29/nexus-7-review-2013/
Since ASUS has made a considerable effort to slim down the new Nexus, we suppose it shouldn't come as much of a surprise to find that the battery is also smaller: it's been shrunk from 4,325mAh to 3,950. This was worrying at first, especially given the extra pixels that need to be lit up. In normal use, we discovered that the device could easily last us at least a day and a half, and we could certainly push it longer by being more conscious about preserving battery life. Gaming and multimedia were unfortunately different stories: we drained the battery nearly 30 percent in just one hour of playing graphically intense games like Riptide. Our video rundown test, which consists of a 1080p movie playing back on an endless loop with the display on 50 percent brightness, yielded a life of seven hours and 15 minutes, which was much poorer than last year's Nexus 7. That tablet lasted nine hours and 49 minutes in the same test.
(Update: many of our commenters have rightly pointed out that the new Nexus 7 has a much brighter display, which may lead to faster battery drain when it's set at the same percentage instead of a nit-for-nit comparison.)

With heavy gaming use, RipTide2 or ShadowGun DeadZone (Online Multiplayer FPS) I average around an hour per 10% or less of battery use so far.

Played Crazy Taxi for about a half hour and dropped 5-6% which I didn't find all that terrible. Can't expect the world from the battery.

You get over ten hours of gaming? That is hard to believe.
According to Anandtech, last year's N7 only got 4 hours during heavy gaming. http://www.anandtech.com/show/6073/the-google-nexus-7-review/7
The N7 also fared poorly compared to every iPad. http://www.anandtech.com/show/6429/ipad-mini-review/8
I give more weight to Anandtech's benchmarks that most others. They are generally the most thorough and technical. Although the above are for the previous gen N7, I'd be shocked if the new model can achieve 10+ hours gaming on a single charge. None of the current gen tablets can do that.

I played Cordy for an hour and it ate 20 to 30% of battery.

Is it possible to adjust max CPU frequency in stock Android 4.3?
N7's cpu/gpu is overkill for most games. Setting a freq ceiling might extend battery life significantly without a noticeable impact on game performance.

There's always an initial drain that is rather fast due to the fact that the charging is not perfectly optimized, notably while it's new. Even though it says 100% it's most likely not the fact. On the other hand due to the large screen the screen uses a lot of power. When using Cyanogen for maybe 20-30 min/day I'm still at 97% the next morning w/o charging. But, I use a lot of mods and settings trying to optimize battery usage. Once you get used to the device and start experimenting with ROM's, settings, mods I'm sure you will find a way to optimize it to your flavor.

The tablet has to scan all directories for media.
Here are some really good tips. You can also shut off a lot of samsung bloatware. I have probably 50 things shut off along with below tips I get amazing battery life and never any lag. Not a fan of magazine touchwiz so using nova and couldn't be happier.
http://forum.xda-developers.com/showthread.php?t=2782239

For a new device, you need to cycle the battery to about 10%, then fully charge, to set the battery meter "high" and "low" flags (some call this "calibrating the battery meter"), before you can expect the battery meter readings to be anywhere accurate.

Lg g3 battery drain issue [ Tried normal methods % have screen shots ]

Guys im sorry but i have rushed a few replies to get the 10 posts but can you please not take this down i need to know if this is legit as my money back only lasts a certain amount
Ok so i bought a lg g3 from ebay, Its legit i have tested with antutu officer but it can get really hot and battery drains very quickly when watching movies and games.
My screen usage is always above 60% but i have screen on 30 seconds and 0% bright. My phone also says that i have used like 1000 mah at 50% but it should say 1500 mah.
I have a d851 and marshmallow and use my phone only with wifi no gps/nfc i also dont have background apps

Why should it say 1500 mah? The screen is not the only thing that drains the battery, you know that, right?
Running any benchmark will cause many battery drain. Don't do that. And that app you have to see the cpu temperature, 42º is not high for CPU. For battery it is.

What help? Get a new battery or go away from Snapdragon devices. And, the screen usage is about right, because i don't know if you know, but the screen you are staring at is 1440x2560, or 2K, which is an insane resolution, and crammed in a 5.5 inch display at 538 ppi, it will consume A LOT. And the battery is just 3AH, which seemed much, but compared to the S5, with a 1080p display and a 2.6AH battery, the G3 has the worst SOT out of the 2014 flagship lineup.

The 2K screen doesn't consume that much power. There are mods which allow you to lower the resolution, but you won't see much or any increase in battery life or performance (maybe in games it's going to be most noticeable).

Sounds like a bad battery. Quite possibly a reason why the other person decided to sell it in the first place. How old is the device that you purchases?
You can get an original replacement battery online for a few dollars. Just make sure you use a reputable vendor, like LG's official website.

Its brand new thats why i'm worried and i have downloaded a few battery checking apps and they say battery health is good.
But when i add up usage it totals lower then the battery capacity, they total up to 1000mah at 50%, when it should be 1500mah
Do you have any benchmarks i can try so i can see if its working right or its just me.

Oh so it's a brand new LG? How many hours of screen usage are you getting, what usage (web browsing, checking email or playing games?) and with what period of idle time.
Don't trust the numbers in the battery stats, especially in a new ROM. They are supposed to get better over time but I've found them to be wildly inaccurate even on months old ROM. I haven't really found an application you can benchmark accurately with.
But you compare with other (real) results on the foruns and rather you get the hang of what's the normal usage you should be getting out of a good battery.

Did you make a day without running any benchmark apps? What is your SOT? Standby time? Do you have location,wifi,bluetooth,NFC,mobile data on?
All of this matters. You shouldn't start right away with "I have problems with my battery" if you are running benchmark apps. Benchmark apps drains battery!
Wait a few days without running that apps and see how it manages. Another thing. The battery stats, the mah usage, not all of the things appears in the default android battery stats. And another thing, the battery value (the percentage of the battery), it is an approximation. Sometimes it could go up without charging, it is because it detected that has a wrong value. You could try charge your phone to 100%, usage it normally until 0%, until it turns off. Then charge it again to 100% and use it normally (don't discharge to 0% to many times, it just hurts the battery).

Oh so it's a brand new LG? How many hours of screen usage are you getting, what usage (web browsing, checking email or playing games?) and with what period of idle time.
Don't trust the numbers in the battery stats, especially in a new ROM. They are supposed to get better over time but I've found them to be wildly inaccurate even on months old ROM. I haven't really found an application you can benchmark accurately with.
But you compare with other (real) results on the foruns and rather you get the hang of what's the normal usage you should be getting out of a good battery.

Did you make a day without running any benchmark apps? What is your SOT? Standby time? Do you have location,wifi,bluetooth,NFC,mobile data on?

Streamed from the internet with at least 1h10 SOT, that is not bad. That is almost 4 hours SOT. If you have 1h12 minutes SOT, that is 4 hours. It is good.

Oh yeah, considering you even streamed the movie, it's signs of a good new and healthy battery. 3 hours of SoT with internet browsing is quite the norm, and 4 hours is on the up side.
I can barely get to 2 hours of SoT with my now aging battery.

It's not about the software side of things, it's about that my battery is old now, and that's why happens to old batteries, the just deteriorate.
Thankfully the LG G3 has an easily replaceable battery, and I have a replacement waiting for me. Not getting a phone on which you can't remove the battery..
And never found those apps like Greenify to really work, at least in the last few years of Android. The OS seems to be doing just of a good a job and I see no improvement in battery life. Maybe they help in cases with poorly written apps that are draining your battery in the background, but I don't see why would you use such a software in the first place.
