Does having usb debugging on effect battery? I left it on today and noticed horrible battery life, phone was at 15 percent at three pm lol, minimul usage. I am running a over clocked undervolted kernel woud that have something to do with it?

I'd guess the overclocked kernel is your issue. Also, check your battery usage in settings and/or spare parts to see anything that stands out. If you have high cell standby usage or a high running time, that would also be a culprit.
I've been running OTB Test 5 1.3 for several weeks now and have great battery life, much better than stock. I would look in your battery usage to see whats using up all the battery like imnuts said. High cell standby drains battery really bad so if thats up there then I would start using airplane mode more often.
Its at three percent. Airplane mode is not an option, then I could miss important texts correct? And not be able to use internet right? Yes battery life is horrid right now. I tried using set cpu to lower cpu during screen off time an my phone just shuts off when the screen is off for any length of time. I do run my screen at 100% tho.. Might just try a different kernel

Profiles in SetCPU don't work on our phones. They cause it to freeze, like you're experiencing.

Is there a reason you need to run at 100% all the time? That's probably your biggest battery drain.
At least try setting to auto.

Alright I did *22899, charged to 100%, turned off and charged again till 100%. Booted then booted into CWR, proceeded to wipe batt stats, Dalv Cache, and Cache Partition. That was at about 1am, went to bed and woke up at 9:30, phone off charger all night and it was at 75%.
Cell standby 41% T/O 9H 50M time without 0%
Screen brightness is up because thats why I bought the phone, this screen is awesome. Battery life was never and issue before I rooted and started with the roms and kernels.
Best I expect with all the antennas on except bluetooth is 7-12% drain overnight. The number one battery killer is the sAMOLED display.
It is rich in contrast and pleasing to look at. The screen resolution is good but a tad grainy. They say the pixels are off when black, but a slight glow is always detectable in a completely dark room (boot up your phone in complete darkness, the black screen looks different on than off). It can also burn in, so I recommend hiding the status bar up top or at least switching to 24h time to prevent the M from burning in. back to topic, there is nothing magic about it for battery drain though. You can do alright if you always work in black background screens, but in many cases you are doing worse than an LCD. Don't expect more than 2.5 hours of active use in the best circumstance if you leave it at 100%.

(note GOS since this is propaganda, but the chart is interesting. It implies that our screens burn up to 1.13 watts when full white, which can be 50% or so higher than similar displays. It also contradicts my statement that black pixels are always on)
Apologies again for straying from topic. The display was the main factor that made me pick Samsung, and yes I do like it.
Swyped w/ XDA App. When in doubt, mumble.
51% at Noon after moderate use, did a nandroid back up and flashed a theme as well. Theme I flashed is pretty dark and high contrast, so I'm gonna tone down the screen to zero percent, charge it back to 100% and see what the rest of the day is like. Also have had GPS and Sync on at all times as well, going to try it without those for the rest of the day as well.
Do you guys use auto sync and background data? I don't think I really need them, I don't really care about my facebook push notifications, but do care about email...
Hi Guys,
I am on Roto JMI v2 and noticed that the battery consumption on Display is around 60-70% all the time even at minimum brightness and power saving mode. Is that normal? Help?
Cheers!
I am on stock and it's always on 83%, so you are better off. My guess is this reading shows the total battery consumption and not the current battery usage.
Normal. Same for me.
Hey thanks for the reply guys was really confused since read on xda a post where the guy mentions 20% usage on overcome rom

its not a bug, the display is what always eats the battery in devices.
Another thing that puzzles me is that whether I have the brightness at MINIMUM or I have it around 35%, the phone still showed the same %age of battery consumption. So does this mean irrespective of the level of brightness, it is going to consume that much of juice or increases with level of brightness (which is only logical) ?
Also, it seems my battery usage gauge is all messed up! Even after around 5 hrs on standby and intermittent usage, it showed 12 m 5 s. Very strange!
When you set the LCD brightness to minimum, current still run through it to operate, if not it will be totally blank (as in darkness). So, 35% is good enough.
My personal opinion, the battery status is always a bull, I'd never trust it, after experiencing so much battery issue prior to my upgrade. I would just enjoy the fun of owning the tab and when it's time to upgrade (to another tab), nothing else matter..............
So long as it kills my time (by playing games, listening to music, watching youtube), improve my efficiencies (by having the necessary apps), keeping in touch (emails, facebook, Skype, phone calls, etc) and most importantly, it is extremely portable. Other than that, I just charge it before I go to bed.
It serves my daily needs. I am happy.
Since I've upgraded to EB13, my battery usage details for "Display" have been a lot higher than normal, even when the screen is used very conservatively, it seems to always be in the 90%'s. I have my screen brightness locked on the lowest setting. The screen brightness is more than high enough when indoors, even at the lowest setting. Is there a mod or hack to lower it even more?
Before, when on DL18, even when my screen on time was high, "Display" was never in the 90%'s, and "cell stand by" was more than my current 5%, haha.
Please post your "Display" battery usage detail percentage and what android version you are currently on for comparison.
*edit* I am running midNIGHT ROM 4.1 and Genocide EB13 0.3a kernel
Pretty sure this is a bug. I always have my display set at the highest setting and I am getting like 2-3x less screen on time per battery charge. Not worried about it yet since I have a backup battery, but it is certainly something I will keep an eye on.
If your using undervolted kernels, the display will have a higher percentage because the CPU is using less, while the display uses the same.
Its a bug in eb13. The "Battery usage" in the settings always shows my display @ 90%. I don't trust it anymore, cause it is now displaying inaccurate information
Sent from my never been rooted, stock Froyo Epic.
Since eb13, all, mine shows is display and cell standby. No wifi (use it all day) or anything else. Seems to be a useless graphical representation now.
I used to enjoy the decreased brightness kernel for 2.1. I'd love to see that mod in a froyo kernel.
fwiw, I'd also love to see supercurios sound mods...
Do you not use your phone for actual calls? Mine shows:
Display 70% - 1h 7m on
Voice Calls 12%, 18m 5s on
Cell Standby 11%, 0% without signal
Phone Idle 5%
WI-FI 1%
This is after 12h 21m unplugged
Download an app from the market called Screen Filter. Let's you lower brightness a lot more, great when you're in bed or something for example.

I have noticed this too, I swear its lumping more than just the screen into the "display" category. I use the display at the lowest brightness possible, and even with the screen on for very short periods of time display is usually using 70-90%
I noticed this on DK28 also, seems to be something different in how samsung records battery usage in froyo.
My current time - 16h 50m from unplug @ 100%
DISPLAY - 65% (51 m, 9s)
Cell Standby - 18% (4% TWS)
Phone Idle 9%
Voice Calls - 5% (4m 41s)
Wifi - 4% (1h 58m)
Currently 18% total battery left
No where in here is the several hours of music/podcasts that I listened to at work today accounted for. Seems like our battery meters aren't telling us the whole story.

Awesome, that works great with the use of an app.
Would still be nice if the devs incorporated into their kernels for EB13 like they did in DI18 though.
Has anyone done back to back tests of using Power Saving mode through a whole charge vs. not?
I have done this, I was able to increase my battery life by more than 1 hour. I did have to disable the background screen setting however, it didn't work great with the stock email app, and my emails appeared blank, because it would change the text to white, but not change the background to black.
I'm in the process of doing this
it worked reasonably well, probably about 20% or so improvement. I then uninstalled a bunch of bloat and lowered brightness more and have it at 2 days with light use.
I'm trying to figure this out as well. Although I can very easily tell the difference with power savings on, it DEFINITELY takes a performance hit. If it nets less than an hour improvement, totally not worth the performance hit.
I was able to make it all through today and finished with 28%, all with power savings off. I think the auto brightness tends to keep the screen a little too bright for indoor settings, so I turned that off and went with a nice low level.
I might try power savings without the CPU limit option checked. What power savings is applied to the screen? Is it just refresh rate and brightness?
I noticed a difference when using screen power saving. The description says it causes slightly lower frame rates which I haven't actually noticed. But I did notice lower battery usage from the screen.
I didn't want to touch the CPU savings because I don't really want to sacrifice performance to save battery.

Now that the masses are receiving their devices and it officially launched at Tmo stores nationwide (well most) how about some battery life experiences?
We all know all too well how battery life can vary and there is NO real way to measure except to give our individual results. Please keep in mind that trying to compare your battery life to another is futile
KISS keep it simple. Give approximates, don't be anal like me (or be specific it's okay)!
Just name your provider and if root/unlock, # of apps installed, WiFi vs Cellular percentage, average cell strength, SOT (screen on time) and whether or not using adaptive brightness and at what %, your typical usage (how you used your phone including GPS usage, talk time, and streaming), and a couple of screenies showing what ya got.
I'll start it off with my first day with the phone. I charged it to 92% and have had it off since ~11:30AM today.
T-Mobile stock no root no unlock
55 apps
WiFi 80% Cellular 20%
105dBm average
SOT is 2hr 55min with 50% battery left. Adaptive brightness ON always @ 50%
Ambient OFF
Syncing all Google apps, I use GNow, 2 push email, and weather every hour. I text and browse web throughout the day and talked on phone ~20min. GPS on battery save
For my first cycle I'm very pleased!
That's about the same as my moto x, so average?
Here's my moto x (2013) battery usage.
Auto brightness, 2-3 bars most of the day on Sprint's network. YouTube, monument valley, reddit, browser, gmail, twitter, bluetooth, locations, google now, and other apps.
On target for 6 hours SOT. It probably wont make it to 6 but 5+ is my bare minimum so it looks like you will make it without any issues. After the kernels and tweaks come I believe we can hit 7 hours or close to it.

I don't know, it's my first cycle & day with the phone (in the OP ^).
Throughout my many years with Android this will increase quite a bit after a few charge/discharge cycles.
It is a large MotoX after all

That would be great, plus google can always release more patches.
I'm on pace to hit about 4 hours of SOT. Using WiFi only right now as my local LTE signal is worse on the nexus vs my 6+, which us shocking BC I remember motorola having great radios back when I was an avid android user. I do love both platforms so no bias here at all lol. Love this nexus and where android stands with lollipop. Probably going to stick with my 6+ as my primary for now. I really wish we could see SOT for the 6+ BC it is an absolute BEAST in that area. I can't run the dang thing down unless I try and even then it is exhausting. For you recent android users, what is the typical SOT these days for the phones with such big batteries and high res screens? Is it really the screen that kills the batteries so quickly in comparison to the lower res screen on the iPhone phablet?
My first full charge since I got the phone early this morning and I'm at 2 hours sot at 70%. Brightness is at about 90% with adaptive on. Watched a few utube bids and browsed around all on 4g

When people are posting SOT I would like to also know whether adaptive brightness is being used or not. I'll gladly post some screenshots in the coming days once my battery gets a few cycles on it.

Great point I'll add that thanks :good:
Mine is activated on verizon and i feel like im having excessive battery drain.
My first full discharge had over 3 hours of screen on time and went from early afternoon to the next morning. How are people getting 6 hours?
Today i charged it up when i returned home from work. Only a few hours on the battery and only 48 minutes of screen time so far on this discharge and I'm at 70% as of writing this post through the phone. Adaptive brightness is off and the brightness has been set low (1/4th brightness or less depending on light, with screenfilter on to make it dimmer than normal when needed). Also, data is off and only wifi is on for data. Ok google detection is on though and i noticed recently that its not taking my commands with the screen off even though its set to.
Finally, the thing gets very hot when using it, especially when charging.
Edit: picture of the battery stats the morning after I made this post. It's nice that the battery practically flat lines at night when I also turn off cell data and WiFi. However, something is waking my phone and I don't know what it is, maybe its auto sync. I can't seem to figure out how to turn off auto sync with android 5.0 so I can test that.
I think it is better also to specify how much percentage of the adaptive brightness.
Because you can set it to 100% or lower, like 30%.
That would affect the battery, no?

On my third discharge with WiFi only and brightness maybe 1/4 inch turned up from all the way down. Ambient display on. Not sure my battery life is up to par.
If I need to an anymore info just let me know. Haven't been on Android in a minute.
