Ill make this plain and simple, im having really high display percentage on my N1 and i cant figure it out. As u can see the picture below, the display % is at a 81%!!! and here is the thing, i have only 4 widgets running. At the time that i took the pic i had the brightness at 30% but even if i have it at 0% display % will always be around 60-75%.
This is what i have on my N1:
Rom: cyanogen 506
Kernel: persiansown uv-oc
So this being said, this display problem is affecting my battery. i get an average of 12-16 hrs which its pretty good, i think but i used to get 32-36 hrs. Can anyone know what could be the problem? Cuz im totally stumped
do you keep your screen on for long periods of time?

oh no, i turn it off when i dont use it. i have the screen timed out at 2min, 1 min, 30sec, ect.. and still get same results.
correct me if im wrong, but i think the battery status (usage) is staggered. Meaning itll post every thing that uses the battery and will display in percentages and will total to =/- 100%.
So if the rest of the phone is only using 19% then your screen would then display around 80%. Lets say the rest of the phone is using 50%, then your battery would then display around 50% of battery use. But its still using the same power consumption with the two instances.
again, correct me if im wrong, i briefly remember reading that somewhere. Cause i guess someone had been using the phone with 50% brightness and when he decided to put it at about 10% he actually increased 2% on his display usuage. hahaahha!

On Desire ROMs it's only 17%.. or sometimes lower. I don't really care though.. Lol.
It is all relative, always adding up to 100%. If you're phone/wifi/3g/cell percentage is really low, then the display will be really high. The higher the display is shows how good the rest of the system is at conserving power. The display is the largest battery drain on the system. If something else was higher, or even close to the display use after you've used the display for a while I'd be scared something was wrong.
Let's say you charge your phone, never turn on the display, and leave it sitting for 5 hours. Then check percentage. Cell idle, Android OS, and things like that will be the largest, totalling 100% battery use. But your battery may only be down 10%. Then use it for an hour with the display on, display will suddenly jump up to 80% and everything else down to 20%.
Or in other words. Let's say you have used 20% of the battery (battery level is down to 80%) On the battery usage screen display takes up 90% of that, and the rest of the system 10%. That means out of the 20% you used of the battery, 18% was used by the display, and 2% by everything else.
People think Cyanogenmod is bad because the display is so high compared to other mods, but it means that the rest of the system in cyanogenmod is actually more power efficient than the others. So display will naturally be higher relative to everything else.
I believe this is a known issue with 2.1
so i guess in a way its saving power,right? since it is not didtributing power all over the place.
i think its because of the Screen AMOLED is probably a battery eater, i think its fixed and its called Super AMOLED
So I notice that an hour on wifi surfing the web took about 20% or more of thE battery...even playing game doesn't do that to the battery. Anyone experiencing similar thing? Anyone with 3g, is data looking the battery too?
Just keeping wifi turned on is also drains the battery for me.
Check your screen luminosity.it is the biggest battery killer
I'm running the Moto234_eVo_Carbon_V0.3 build and I've noticed that even with the screen off and the phone idle my battery drains at a pretty good rate when compared to WinMo. Any fixes for this?
for me 3g/h draw much power than wifi, almost 1.5x-2x of the wifi surfing..
Screen brightness is easily the biggest batter drain keep brightness as low as possible,
Data connection will hog more than WiFi if you are in an area of weak signal and your device is constantly searching for a signal, when your at home or work using WiFi just turn data off and switch to only 2g networks, set setcpu to screen off 245 245

Screen brightness definitely hits it hard, then wifi and bluetooth, keep em off whenever you are not using them and of course apps running in the background, grab a task killer, if its not needed, it shouldnt be running or else it will use power.

Get "current widget" from the market to see how much powers are being used. While screen off, my phone only drain about 4~7 mA...
I just came across this. Super detailed analysis of battery usage.

3g draws much more power than wifi. If wifi is available use it over 3g. But like others have said, the screen is by far the biggest battery hog.

I don't see how the screen is the biggest energy hog. When I leave my phone uncharged untouched over night and it it displays 7mah on current widget, I lose 40% battery in 7 hours.

That's unusual...i lose less than 10% over night...even with bad reception in my room, that didn't kill my battery. Maybe you can try this to test it out. Fully charge before you go to sleep. The next morning, check your battery in setting to see what is using the majority of the battery drain during that period...this might help you find the reason...
If noting else is running, Cell standby will eat the majority of the battery power.

You need to reinstall new build and do a task29 and format your SD your battery stats are all over at 7mA you should see 1% per hour

Yes thats true, exactly the same in my HD2: 3-7mA = 1% an hour or less
Wow, I installed Mdeejay_eVo_Sense_v_2.3Revolution to see if this build helped on battery life. I charged my phone over night and had a full battery at 11AM (according to the meter) but by 7:30PM, my phone was completely dead. During this time, I had two 5 minute phone conversations and used GPS for 9 minutes. Other than that, the screen was not active and I didn't have WiFi enabled. Is this typical? Doesn't make running Android very practical on the HD2. This is only the second build I've tried but it's not looking very promising.

Something is wrong with your build. Try his newer build. They got a new kernel. If that were my habits, my battery would drop by only about 25%. You should install "current widget" from the market. It help you keep track of battery usage. On standby, most people and I got about 3~7mA. If you get a higher mA, that mean something is eating your battery.
Please give Mdj's New Build "Froyo Sense Revolution 1.6" that comes with his new kernel which is suppose to make battery last longer. Hope this helps.

i hope this enlightens you and yes wifi kills battery but it is not the biggest battery killer and wifi is more harmful to your battery life if it is not connected which means it is constantly searching for a network which sucks the life out of your battery.
I think the wifi modules on the new kernels (Hastarin > 8 & MDJ) are consuming too much power.
I usually got 5 ~ 8 mA in sleeping mode with my wifi turning on on the previous kernels, but now I got 8~60 mA and the battery status is showing that wifi is taking about 30% of the battery. Maybe this is because the 802.1n is enabled by default!
Whenever I check my battery status, my display is always at 45%. Is this normal? I still get good battery life, I think. For example, I been unplugged for 6h and 18m and I'm just at 70% battery remaining.
I don't know what to tell you; if you aren't doing a lot of CPU intensive tasks, the battery should bbe good for hours.

that's kinda strange, not cuz you are always stuck but because you are showing 45%. I thought the atrix only measures by 10s.

That is exactly what I was thinking. I've never seen anything but increments of 10%.
No....I'm not talking about my battery percentage, I'm talking about my display percentage. Its always the higher of the four...wifi, phone idle and cell standby is always low, like in the single digits low. But the display is always high. Like for example I woke up this morning, checked what was consuming battery and the display was at 65%. If the phone was sleep for the past 4-5 hours thus the display not being on, the display shouldn't be consuming that much battery, so I thought.
I still get great battery life. Im just wondering if anyone else display is also consuming a lot battery and what could be causing it.

Ahhh, ok. I get what you mean now. This is normal for most Android phones with large (4" or bigger), bright screens. As long as you are getting good battery life you are fine. I'm assuming you keep your brightness set to automatic?

Considering you are getting good battery life and your display has that high of a percentage after "sleeping" that long is a good thing. That just means the other processes are running efficiently. You should always expect the Display to take up at least 60% of your battery, especially after a full cycle. What really matters is actual runtime.

But I used my iphone at work to watch videos, ect while there is downtime. I usually watch while it's also on the charger
For the Note series, does anyone know if that "kills" my battery for long term?
I know you can replace battery, but just wondering for future use.
Thanks.
Issue with battery drain due to android system is real
All three people I know that just got the Note 4 were experiencing the same issue I had with excess battery drain with the always generic "android system" taking more battery than anything else including the screen.
I downloaded an app called "System Tuner" and looked the CPU% for Android system and it was a constant 3-4% when the phone was otherwise idle.
I found a post at http://support.t-mobile.com/thread/80459 where they were experiencing the same issue (lose around 12% battery an hour with android system taking a huge chunk of battery). The person from that post was able to address the issue by turning location off, rebooting, turning location on, and rebooting again. After I did this I saw Android system idle at ~0.6% - 1.1% instead. So far I'm getting much better battery life but I'll need to give it some time to know for sure.
Hope this helps!
mine took about 2 full days for everything to finish syncing, downloading, indexing, etc. I had books, news articles, pinned music from google play, etc.
Once that happened, everything is now "normalized" and I'm getting better battery life than I was with the note 3.

Short answer: Maybe, it depends on how you are doing it. Using it while it is charging is not necessarily bad but watching videos and keeping it plugged in while the cell voltage is pegged at 100% will likely deteriorate your battery faster.
Long answer + tips:
Lithium ion batteries are great - they are light, can be made very thin and have excellent energy density but they are also very finiky.
Things to avoid doing with a lithium ion battery
-Charging to 100%, leaving it plugged in overnight is a poor practice(high cell voltages reduce the service life*, stopping the charge at 90%[4.10v] can double the service life, stopping the charge at 80%[4.00v] can quadruple the service life.*)
- Discharging the battery to below ~20% (Li-Ion batteries are somewhat sensitive to deep discharges)
-Charging/exposing Li-Ion to elevated temps or below freezing.
*service life is defined by when a battery can only retain 70% of its rated capacity. Most consumer batteries used in mobile devices have a service life of 500 charge discharge cycles.
It is not uncommon for batteries to lose 30% capacity in 1.5 years or less. Changing your charging and handling habits can double or quadruple a batteries life span.

LOL your picture took up have my damn screen on my 1080p laptop with 15.7 in screen. It was crystal clear too.
On my 2nd charge, auto brightness. Pretty freakin' amazing battery life....
15.5 hours off the charger with 8+ screen on time!
I got awful battery life on the first charge cycle. It drained 50% overnight. 2nd charge has lasted amazingly long and I still have 64% after 12hrs of average use.
First charge. Battery life has been phenomenal. Brightness on auto.
Did u use any power saving features to achieve that time?
Did u use any power saving features to achieve that time?
Definitely improve battery with recent update and I'm a power user
After the latest update
I dont know why but my phone goes from 100-90 in less than a hr with minimal use while the screen is set at auto, also in the leaving it unplugged in the night the battery also drains like 5 points.
I've been at full brightness and using the hell out of it non stop so far, and I'm at 35% with screen on time at 3hrs 40 min.

My GT-I9505 has always had a very poor battery life. However, thanks to Greenify and Amplify I managed to reduce the battery drain during deep sleep almost entirely. However, I noticed huge battery drain when the screen is on, it takes half of the battery and just for less than 2 hours of screen on! The brightness is set to minimum, I use Slimkat's Dark UI which it should help the AMOLED screen, but these battery drops keeps staying (even with other ROMs i have the same battery drain)... A friend of mine has got a Galaxy S5 and its battery is absolutely brilliant, screen takes only 20% in the battery stats and he uses it far more than me... Is this a normal attitude on the S4?

The S5 does have a bigger battery (bigger in terms of mAh). It also depends on the age of the battery. If the phone is new (therefor has a new battery) it obviously lasts longer. It also depends on what you are doing when the screen is on. Do you play games or what?
I usually read on my S4 and it does not drain so much as to go from 100% to 50% in 2 hours. But I'm running lollipop. I've never had any other rom beside original firmware and lollipop gpe.
Check your settings and governor.
