display -- sucking up my battery life - Nexus One Q&A, Help & Troubleshooting

Hello, my phones battery life is I'd say average.
I get up in the morning after its been charging all night, and after its been unplugged for maybe a half hour, with a few texts and a minute of browsing done, the battery has gone down 5%.
Battery usage shows that display is taking up 89% of the usage!
Why is this? Is it normal? If not, how can I fix this?

Display will use most anyway. Get a darker home screen, either use low brightness or auto-brightness. not much else you can do.

Let me guess you're using CyanogenMod?

I've seen reports of my same problem, and those that had it found a solution by wiping the battery statistics, letting it die, then charging it to 100%
But no, my nexus isn't even rooted.

Strange. Before I was rooted my display would always be 1st or 2nd, along with android OS
After I rooted using Cyan, it was always 1st taking up more than 60%
Then I switched ROMS now its always 3rd or even 4th
Sorry dude.. try wiping batty stats and changing your brightness.. are you using live wallpaper? what about screen timeout.

has anyone thought that the battery usage stats has to equal 100% so if the operating system on CM is running lighter (usin the cpu less or in a more efficient way) then the display would be taking more % of battery usage making people think there is something wrong when probably there is nothing wrong. maybe the desire ports (modaco ro king) use more cpu and thats why the display is 3rd or 2nd.

This is perfectly normal. Displays are power hungry relative to the rest of the phones components.
Google maybe shouldn't have included the battery usage page as it just leads to confusion. When you use up 5% of your battery's power and then check the stats and see that the display is listed at 89% it means that of the 5% used, 89% went to powering the display. It does not mean that the screen has used 89% of your total battery at that point.
Leave the phone alone for a while and you'll see that the display percentage will go down while things such as Cell standby will go up.

Nobody thinks of that
-------------------------
I am on more than 9h of use still 50% battery left!
- Autobrightness on
- No taskkiller!!
- Wifi on all the time
...and using it today a lot, mails, web, twitter,....-> made a logcat this morning and eliminated my battery drainers

Agh! I want better battery life! I feel like it's dying much too quickly....

buy a bigger battery

or stop fiddling with it so much, lol
turn the brightness down. turn the sync off. turn off background data. don't use bluetooth or wifi. turn off your location.
don't use live wallpaper, use a darker screen that doesn't move.
i know on my winmo phone if i turned on bluetooth, battery would just get sucked out. i couldn't charge
it as fast as bt used it up. and that was with a fastcharge reg edit.

I believe you just got your phone, right?
It's cause you're playing with it so much.

I dont feel like I am though. I am using it probably just as much as I use any other phone I've had.
Maybe the battery just needs to be broken in.

Nobody ever thinks of that unfortunately. I would think display using the most would mean you're using a pretty efficient device.

Yup. That if you want to keep your battery as long as it can get. Else, if you want to enjoy your phone, buy a spare battery along with the desktop charger and you will survive a day...

I switched to enoms which gave me a little better battery life. Also downloading juice defender made a noticable difference, I use the free version at the default settings. I also switched email to hourly which is adaquate for me. I dont run bluetooth unless I am using it, same with wifi, which is what I do with all my phones. I dont otherwise change my usage, dim the screen etc. Overall I make it through the day with typically about 35% left. Based on what I see here my usage would probably fall into the light to moderate range. To be honest I havent had a smartphone recently that did much better. I pretty much figure I gotta plug in every night in the modern phone world.

As others have mentioned, the display uses the same amount of power no matter what rom you are using. So if display is 3rd or 4th, you have an absolutely crappy rom that is using battery probably 10x as fast (compared to same usage where display is 90% of the battery).
In simple terms, the higher % your battery is using, the more efficient your phone is being.*
*compared to same usage at same brightness running different software.

An addendum to juice defender. I had it on the default setting but changed schedule so that it lit up apn for 3 minutes out of fifteen instead of one, my email wasnt consitently downloading at one minute.
I noticed that you have gone to 5.0.6, how is your batt life now? I stayed away from it just because of the overrwhelming number of bad battery life posts on it and was surprised you went that way.

Froyo battery usage

Hi and greetings from Desire forum
There are few Froyo ports/source builds for HTC Desire. All of the seems to have huge display battery drain (which can be seen in settings/battery usage) for about 80%. Do you might to check how much display is draining on N1 Froyo?
Thx
It is all relative to each other in that screen. If your display is a really high number, then it means that the system, apps, and everything else on your phone is using much less battery.
With the Froyo update, things run faster, and thus finish faster. Using less battery time. The only thing that can't change is the Display amount.
So really, the fact display went up is an awesome thing

Do you mind to check whats your N1 says about it?
I could. My Display is higher than all the others too 75%. But it all really depends on how you use it. I've only had my phone off the charger for an hour or so and browsed a lot with it already.
Unless I do the exact same thing as you, visit the same sites, have the brightness the same for the same duration you had, it is impossible to compare numbers.
The usage is a percentage of time since last unplugged of what each part of your phone used. If I unplugged it and never turned the phone on. Someone phoned me and I talked for an hour, then the display would be very little and the phone would be 80%.
It all depends on the usage.
hopefully you're right and this is just one of the froyo features

Need Help w/ Battery (Yes, I've done my research as best I could)

Ok, so ever since I upgraded to CM6 (which I LOVE) I've had serious battery issues and I've tried to fix it by installing Pershoot's kernel and I have SetCPU to underclock in depending on what battery life it's at. Also, I've wiped my battery stats and I've calibrated my battery already.
Today my battery was at 64% after only 3hr and 26min. I don't have GPS on, auto backlight is on, 3g/2g and sync are on. If it makes any difference I have the Korean radio installed (which btw improved my reception a lot! ). After about 9hrs and half, my nexus one died. As per usage, I wouldn't say it's much at all because I'm in class most of the time and I've only talked on the phone for about 1 min, browsed a few websites, and sent only a few texts.
I keep reading on the forums about how people are getting 1-2% lower per hour while on standby but the % I reported earlier, my battery's draining at over 9%/hr!
I really just want to be one of those people that can say that "I still have 50% left after 12 hours!" lol
So, is there anything else I can to increase battery life? Is my battery just crap? Any recommended setCPU profiles?
If you're one of the users that get really good battery life from your Nexus One, please tell me what you did to get it that high! Thanks!
Don't use setCPU to manage battery life, only to overclock. It overrides the kernel's settings. Sounds like you need to wipe and flash the rom again. Then gradually add applications you want, something is sucking battery life.
Last, buy a new battery.
CM6 has less than stellar battery life. If you check the "help with my battery life" type threads, you will see most of the OP's have CM6 as their ROM. Try another ROM, you will get better results.

Quoted for lies
I'm using CM6 and I get between 22-32 hours on a single charge. I just use the kernel that comes with it and i almost always have sync on. No GPS or bluetooth though.
Are you using a battery you purchased on ebay? Or are you using the stock battery? ebay batteries last me about 9-12 hours and die. The stock battery is amazing
Exactly the same situation as you:
CM6.
N1.
Student.
Experiences massive drainage in short amounts of time with low usage.
Tried everything.
I'll now be trying Enomther, because yes I have heard CM6 users get worse battery life.
Just a viewpoint on what I'm facing. For the past week I've gone to bed with 100% battery and woken up ~7 hours later on 75%. I've tried WCDMA and GSM auto settings and neither male a difference.

Thanks, I'm glad I'm not the only one with this problem. I thought I was being an idiot by doing something wrong...
I've calibrated my battery several times already while trying to fix this issue. Could that have killed my battery life?
1) Discharging the battery below 10-15% is bad for the battery, doing it many time will destroy the battery, making it last just about nothing.
2) Check CPU usage - download System Monitor or some other app like that, and check the running frequency of the phone. When you just run the program and don't touch the phone, it should float around 300 MHz. If you have it locked on 998MHz - you have an app that got your CPU stuck in a loop.
3) Download some app that stores battery stats, and check your discharge current and battery capacity - that way you'll know if it's your battery dead or your apps drawing the juice.
Sorry, double post.

crap, all the guides that i've read regarding calibration told me to discharge it completely.
My CPU usage seemed normal. It was stable at around 245 and would jump up to 998 from time to time that doesn't last for more than half a second though.
My battery seems to be in good condition as it's labeled as "healthy" by my battery apps and the voltage seemed normal....
lol at this thread...
http://forum.xda-developers.com/showthread.php?t=714184
Do a nandroid back-up of CM6, and then try out the above ROM. You can always go right back to CM at any time.
For calibration, complete discharge is necessary. Doing it once is not too harmful. As long as the battery is reported "healthy" - you're ok.
There are apps that will show you the approximate capacity of your battery in numbers. Try to find one like that.
Please check discharge current and voltage over time. It doesn't make sense that a phone on 245 MHz in sleep mode will draw the current required to discharge 10%/hour.
in same boat as OP
im in the same position as the OP
student.
dont use phone for nearly 7 hrs a day
backlight on lowest, gps and bluetooth off.
ive been looking around for answers (hence why im reading this)
when class gets out ive gone from 100% to nearly 65%
running cm6 and ive wiped battery,
about to switch ROM, maybe that'll help.

Awesome, if you find a fix let me know please.
I haven't been able to do any of the suggestions yet but (when it comes to flashing) but I do have an update that might shine more light on this issue.
Today in class I noticed that my N1 was warm when it was in my pocket but nothing was running and gps and bluetooth was off. I checked the temp of my battery it was at 36.1C while it's usually at 30-31C when I'm not doing anything.
Also, I checked spare parts this morning and found that, while I was asleep, my N1 was not asleep for half that time but my screen on for only 4% of that time (probably from my messing with it before and a little bit after sleep).
I've checked to see if anything is running in the background that might lead to this but so far none of my apps should drain my battery that much while I was asleep.
Is this normal? Shouldn't my phone be mostly in sleep mode when I'm asleep since I'm not doing anything to it? As for the battery heating up, do y'all think it's a faulty battery or the fault of the OS?
Thanks again for all of y'all's helpful replies!

About battery heating...
I checked and mine is at 75-78F while in class. My n1 is also in a case, so for it to be that low is good. Just thought to throw that in as a comparison.
Also i've switched ROMs to help with battery, no luck there. Still experience 7-8% drop per hour.
I've been keeping my phone off now at school, which has helped, though I still lose nearly 15% while it's off.
Sent from my seXus One using XDA App. While I gripe about battery stats.

Battery not so good

I didn't use the note much, but it needs to charge each day. This is bad than tablet. Any software to save battery? I tried 'air plane mode' sofeware, but it also turns off phone after sleep.

What apps and widgets are you running? Have you gone through 2 or 3 full discharge/recharge cycles? There are apps out there that can detect if any app is consuming your battery but you will have to search the forums as I don't know of any first hand.
Also, which ROM are you using? When I was using Rocket Rom v22 with AbyssKernel 4.1, my Note would last more than a day on the same charge even with moderate use. Give that a try as it also really boosts performance.
I'm currently on Team Rocket Rom (ICS based) v5 but have not used it extensively to comment on battery yet. So far with 3 activesync email accounts (all push), some widgets running (weather, clock, etc.) and the Note sitting idle consume about 2-3% battery per hour. Will monitor this.
most smartphones ned to be charged every day, what battery life are you expecting to get ?
battery depends on the usage and applications you installed on the phone.
have you tried rooting already? usually custom roms have the best alternatives of extending your phone's battery and giving it an optimal performance.
Try to stop some bloatwares that your phone's loading up everytime it starts up(from rebooting)

I am using la2 rom. Here i attached an picture.
Geez... i personally feel that one day charge is reasonable especially with the juice required to drive the big display.
Anyway, Juice Defender premium is one app that has helped me, and may help you too.
Since you got Activesync, with the premium version of JD, you can customize app to be excluded from 'power saving', so that the inbox is up to date.
+1 for juicedefender.
Other tips that may not be obvious to first-time smartphone owners are:
1. Set your screen brightness to auto. You don't need the brightness cranked right up all the time.
2. Disable bluetooth and GPS if you're not using them. Juicedefender will do a pretty good job of managing your other radios.
3. If you've got email syncing set up on your phone, set it to check as rarely as you can put up with. Push email uses a LOT of battery life, and even a scheduled check can blaze through your battery if it's happening often enough.
4. If you've put on a custom ROM your phone may be reporting inaccurate battery stats. Give it a full charge, boot into clockwork recovery and wipe your battery stats. You'll find a few days after that your phone will start reporting more accurately.
Good luck, and if any of this was unclear feel free to ask further questions.

Try a later ROM to see if the same issue exists. I think you should instal rocket rom v22 - you'll be happy with performance and battery life based on your usage.
try to calibrate your battery as well... there are many apps out there that offers better battery calibration or you can do a manual calibration as well.
Give it some time and upgrade your ROM
I am getting great battery life. It runs for full day (24 hrs) with 30% of battery usage. though in a day i dont use it much, just 5 to 10 calls of around half an hour to 40 minutes.. data and gps always on.. screen brightness on auto...
My note running the OEM battery last me about 6 hrs.
Averages about 45mins talk time/day
About 50 SMS/day
Screen brightness set to 100
Checks email every 5 mins
Using a live wallpaper
Refreshes the daily weather using Accuweather every hr
Bluetooth always turned on
Battery Widget
Fancy Widget
ESPN scoreboard ticker widget refreshes
Twitter running all day
Facebook Widget syncing all day

^ This. Or better yet, just always set your brightness to the lowest brightness setting, 50% afaik. And use black/dark wallpapers and always turn on night mode (if applicable, especially when using your browser)
If in case you need to adjust the brightness, you don't have to go through the jungle of settings, just click notification bar and slide horizontally to change to your preferred brightness.
Jd is hit n miss will actually helping out. If your phone sleeps a lot jd is nice at keeping cell or wifi off if your like me and on it every 10 minutes then toggling data and other things can consume more juice. .... I have tried with and without on my tablets and phones and see no big difference depending on use.
Sent from my Ice Creamy Galaxy NOTE
I was pretty happy with my battery until two days ago. I use my note very little, for e-mail checking (which I pull manually) a few times a day, and to make two or three phone calls per day. I also text my kids occasionally. GPS and Bluetooth are off most of the time. Battery used to last me about two and a half days under these conditions, which seemed reasonable to me. All of a sudden, two days ago, I charged my battery, and after a full charge it drained 60% overnight. Thought that it was a fluke, so rebooted my phone, fully charged again, and the same thing (over half of the juice gone overnight) happened again. Battery stats tell me that Android OS were 100% responsible for overnight drainage. Any clues? I am on stock ROM, by the way.
Thank you.

Get a good app to check what is using the battery or keeping the phone awake. This last is the most likely.
Baddass Battery Monitor is my recommendation.
Not a single phone call, only used about 10 mins. after 21 hours only 11% left. Install Jd with 'balanced' option.

Ok, I used the Badass monitor to see what's going on. Once again, no phone usage, quick overnight battery drainage. Android OS 100% responsible, and the main power sucker is the Kernel (96%). Why is this happening? And, is there a remedy? I have changed nothing that would trigger this! My Note is still within the return window, so if there is anything wrong with it, I will return it.
Thanks again.

Badass Monitor is very useful, my note was drained by Dolphin Browser, it used 38% of battery. Seems like for this browser, if I only press home key to exit, It will keep running?
I think the reason the battery drain fast is we press 'home' key to return to main menu, that will keep a lot of apps run in the background.

Screen Brightness kills battery more than you'd think

So the poor battery life on my Note 4 might have more to do with screen brightness than I would have expected. Unfortunately, most people posting their SOT's aren't doing it in a very scientific way, so it's hard to know what we should expect from these devices.
Here are my battery test results using PCMark for Android https://play.google.com/store/apps/details?id=com.futuremark.pcmark.android.benchmark
In one test, I put the screen brightness to 100% and the results were pretty dismal. In the second test, I ran it at 50% brightness, which is brighter than the Note 2 at full and the results were much better.
I use Auto brightness during the day, which might explain my poor battery life, but I'd love to know what others score on PCMark are (it does run for 5+ hours!). I do keep my background BLACK, as well as using black themes on everything I can - for apps that only have white backgrounds, I use AutomateIt to invert the colors automatically. I would have thought these black backgrounds would do more, but it really comes down to brightness it seems.
I'm using an Exynos N910U model and left wifi connected while doing this test - 3 google accounts are synced on my device.

thanks for tests im using my exynos version on auto brightness and generally get 6 hours SOT. i saw on alot of people s stats and people who has problems generally has google play services on their battery usage list and it definetly shouldnt be at there... its probably about location reports to google every1 should disable it from location settings it doesnt break anything.

Yes, location can be an issue, but I think that impacts standby time more than SOT. Currently I've done the following to help with location-related issues:
- used lion tamer (soon to be called amplify) to slow down NLP wakelocks.
- set my location settings to powersave mode
- setup AutomateIt to turn on GPS when I'm in Google Maps (I'm usually plugged into the car outlet, so battery isn't a concern while navigating.
- Greenify stuff like Google search, Maps and several others.
I like and use Location Reporting, so disabling it outright isn't an option. My standby usage is very good at usually less than 1% an hour and my wakelocks keep my device awake usually less than 6%, but I'm still working to lower that number.

last night with 10 hours sleep time. with wifi connected sync was activated for 3 mails. i just lost 2% and i didnt do anything special like you did. no greenify no root nothing i couldnt even install wakelock detector cuz its broken on kitkat without root.
. i just disabled some useless stuff like samsung store etc.. everything else is working. and on my car i generally listen music over bluetooth
Lux could help

Before I started tweaking, I was getting around 6%-9% drain PER HOUR! Disabling stuff without root only got me so far, then the xposed tweaks and Titanium Backup had to be used.

like i said i dont know whats wrong for some people its probably something you installed(skype maybe) or mostly about location reporting. even last night i left my phone at 90% when i get it this morning after like 10 hours it was on 88% like i said earlier wifi was connected no power saving etc just normal idle time nothing special.

I was testing without any apps installed (just whatever I used to record battery consumption) and it was crazy high. Then I started adding accounts and apps, tweaking and I got my standby time to be much lower, but SOT leaves much to be desired. I'm going to try using the manual brightness and see if there are any differences - I often find auto brightness to be too bright or too dim! No "sweet spot" found! LOL
Greeny can also help but may need root
I'd suggest changing the settings for your Battery Monitor Widget app. AFAICS it polls every 10 minutes so a wakelock occurs every ten minutes to save the data. Use something like an hour and see what happens. Also would highly recommend BetterBatteryStats, a free version is available here for members.

I'll try that, although that might only improve wakelocks, not screen on time.
BBS never worked right for me. Always complaining that it couldn't retrieve the stats or falling back on something else.

Wait, with the screen off? Then you have something horribly wrong with your device. Mine did a few % over a night. With nothing done to the phone to conserve battery at all. Snapdragon, though. With the update.
I loose only 2% for 7h of standby last night.
We are seeing a trend I think, I noticed that it's mainly us 910U users or exnyos users complaining about battery life. So it must be something in the 910U rom?
I've got a 910F and I get 6 hours screen on time maximum :/

Doesn't happen now that I've rooted and applied my standard tweaks, but I tried a factory reset to see if I could correct the high standby drain and was not successful without these tweaks.

I have 910f and i got same issues with my batt.
i've tried clean system, root, custom rom. Battery is always draining higher than some people.
As i said in other thread: some people have an issue, some have great battery life. And nobody knows why
Maybe it's the guys who keep it stock and don't root, custom rom and "tweak" that get the good battery life.
Delete it pls.

I'm on stock, but without tweaks I can't even go the day on standby. [emoji31]

[Q] Battery Drain Rate - Is this normal?

Hello, I have just a got an XT1254 for around a week so I am still testing the device. Battery is always my biggest concern for every phone I had and therefore I like droid turbo's big battery.
After I have got the device, I tried to debloat most of the moto/verizon/amazon apps and managed to get only 1%-2% drain during sleep overnight. I haven't installed many apps at this moment, as I am testing how long I can get with minimal usage for one charge. It is now more than 2.5 days after charge and I have 62% left, and I disabled almost all censors. and only turn on data/wireless only when necessary.
My problem is, I still get a, I think, quite fast battery drain when screen on. I am not watching video or playing games, I just use whatsapp or test camera, not even facebook, and I get 1% drain in 2-3 minutes. What I want to ask is, is this normal? Or is there anything I can do to reduce further? I think the screen eats most of the battery, and I used auto brightness, or manually to 10% brightness indoor, with dark wallpaper in launcher already.
I have no plan to root at this moment, but I think the processor speed can be lowered. Is there anything I can tweak about the processor?
Thank you very much for answering!

Besides, you should know that KitKat stand by time is horrible. I passed from around 10% battery drain overnight to around 2% with Lollipop. You need root to tweak the processor.

Thank you and I have tried to read the posts. The google play service doesn't seem to be the problem of my device. The drain during sleep is somewhat acceptable, and anyway I need to keep background data on for play service. My problem is, when screen on, it drains 1% in 2-3 minutes doing simple tasks like whatsapp and camera, and the brightness is already either auto or minimum. And my point is, given the huge battery and nothing serious being done, it still drains more than my previous phone (sony m2 also running kitkat 4.4.4)

You should take a look at the apps you have installed, besides this, I think the drain is pretty normal for a QHD screen. Remember there are great number of pixels to move in this screen, so the battery also suffers from this.

I attach a screen capture of my battery screen.
My phone is new and I haven't installed many things. Just nova launcher plus some widgets. BTW, may I ask whether phone idle contribute 25% of power is normal. Yes I mostly leave the phone standby and actually do not have real use except phone, sms and whatsapp.

I don't see anything wrong with the drain, all is perfectly normal. Phone idle is on top when you don't use the phone, so I think you have no problems at all.
