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.
I just bought a new Captivate (first android device) which I upgrade to from a Nokia E63. I've been playing around adjusting settings etc. and I noticed that my battery is more than 20% drained already! Is there something wrong with my model? If not, what can I do to save my battery for when I really need it?
If all you're doing is playing with it yes its gonna go down. Also depends on what programs is any you have running in the back ground. Furthermore if your wifi Bluetooth and GPS are all on there's another drainer. Last make sure you have the latest update. Usually the out of the box captivates don't have the 2.2 so use the kies program that's on the disk that came with it.

If the battery is new its going to drain quickly at the beginning, after a couple of recharges its going to get better. Other than that i would set the display brightness to auto and i'd download green power free from the market to toggle wifi/data and have it turn on for 1 minute every 15 minutes to save the battery.
i never understand why people complain about battery life cause i can go more than a day without charging, but here are some tricks. turn off wifi, and blue tooth. also under volt your cpu to save more power. also get a dark background because amold screens use no power when displaying black.
It is all in the way You use it.When you are surfing the net and just all around using the crap out of the phone battery life will be horrible. once the new smartphone phase wears out that battery life will come back up. On moderate use I get a day or better. on heavy use I get 4 to 7 hours maybe.

Big difference regarding the display technology between the two phones. It's the price you pay for the AMOLED.
Don't use auto brightness and keep the setting to its lowest if at all possible. An app called Screen Filter is helpful during night time reading.
Just make sure you let your battery drain until your phone shuts off and give it a full charge. You should be good from there.
Battery Dr is a good apparently. Just fyi

I'm coming from a note 3 that I used the same if not more than my nexus.
I don't use it heavily and unless I charge it during the day it's dead by 4pm after coming off a change at 5am. So 11 hours life.
Ambient display is off, I use Wi-Fi when available, screen brightness is dimmer than auto brightness sets it to. I've stopped using all widgets, which sucks. I'm currently on a CM12 build with the memory leak fix and still getting horrible life. I'm at 76% right now, 3.5 hours up time.
Is this normal? At the end of the day on my note 3i would still be above 50%, I assumed since this had the same battery size that it would be somewhat similar.
Thanks for the suggestions. I'm open to changing settings or ROM's if there is something better.

Whats your signal strength like? How much time is your screen on for?
Hard to help without seeing detailed battery stats, screen shots etc.
Attached a screenshot of where I'm at right now. I left hone an hour ago where I was on WiFi and have had excellent coverage since then. I do have bad coverage in my office so I use Wi-Fi there instead.

Its nhot really enough on its own. You'd need to go into screen and screenshot that and also into teh graph itself and screemnshot that at a minimum..
I didn't realize that you can dive in even further on those results. I've turned off detailed location and reduced the screen brightness even further and it seems to be making a difference. It's estimating I'll be able to go about 10 hours from now.
Don't k kw what I am doing wrong. Not doing any fancy stuff. Screen in time 1hour and already down to 65%..?
Well, there's a lot of things that can affect the phone:
1. What's your screen resolution at?
2. What were you doing for that hour? Using active aps with constant data transfer (like streaming services or live games)?
3. How bright is your screen set? I keep mine at about 35%
4. Are you running any of the battery saver options?
5. What's your performance mode set to?
With my screen resolution dropped down to the lowest setting, my brightness at 35%, and no power saving features, I can read for three and a half hours on the FanFiction app, and not even drop to 70%.
Boot up in safe mode and see if it still bad. If not, is the crap you installed, if it is, then something with the system, probably some settings. Also, if you just got the phone, give it few days, it's probably syncing and updating. Mine is at 9 hrs since full charge, 1h 10min SOT plus 1 hour AOD I'm at 80% and I know I can do better if I put some effort in it. I got everything on, max resolution, NFC, BT, GPS, wifi it's all on.

This ^^
On that note, thread closed.
So i got my S21 Ultra a couple of weeks ago and the battery life isn't as good as people tell it to be... I wonder if this is normal or i have a faulty unit
Important: i am running the latest update on my exynos device (february security patch as of the making of this thread)
What do you expect? You have used the phone almost 12 hours, used Samsung Music for nearly 8 hours and still have 78% battery left lol. This is great.

The SoT is pretty crap i can only get 5 to 6 hours if i'm lucky, all i do is watch youtube and netflix and nothing else pretty much, and since SoT is pretty important to me idk if i should wait for an update or get another unit
If you are comparing to a Chinese phone, I would agree that the battery life is not great. Before buying S21 Ultra(exynos), I was using Mi 10T pro. It has better battery performance than S21 Ultra. The other thing that I dislike about would be the heat issue on S21 Ultra. Its horrible.
SOT is only one measure of battery life, the battery still depletes when the screen is off, especially if you're doing something like listening to music for 7 hours......
If you saw the YouTube 'battery drain' tests, the majority are in a room, mobile turned off and on WIFI. They are in constant use with minimal ramping/up down of the processor as they only switch apps every hour. These guys achieve up to 9 hours with constant use in optimal conditions.
If you extrapolate out your current usage you're on for 7 hours with 51 hours total, which is very very strong. People would kill for that endurance
At best you can expect 0.5% an hour drain if you aren't using the phone, but that's if you literally leave it overnight and don't touch it. More likely it'll be between 1-2% depending on usage, so if you calculate you've had roughly 10 hours of screen off, that's about 10% battery that isn't being used on screen on time, which equates to roughly an hour of SOT 'missed out on' if you were just to run the device with the screen on for the sake of it.
If you're truly only concerned about SOT, run a day without music in the background and see the improvement. It's a nonsensical thing to do as that's not how you use your phone, but will get you the numbers you want...
You're also using a high end processor and a large screen with a high refresh rate, it's going to use more juice than a mid range or low end phone. If you send that phone back, someone else is going to be very happy when they get it as their replacement

With my s21 ultta i can easily achieve 10-12hours of sot with browsjng and youtube on wlan with total runtime of 48hours.on mobile data its a good 35% less (also cause of brighter screen outdoors) but Overall its good battery life for me (note im debloated and using Samsung browser with darkmode!!)
I'm doing OK on the battery. Turned off goggle discover on side screen has helped aswell as 5g disabled as I don't have it where I live atm

Yes if you want the same smoothness and a good 10% better battery you can use the 96hz mod
Put brightness on manual. The display eats a lot of the battery. Try to keep it at 50% or less.
Turn off all animations and use dark mode/dark wallpapers. Junk like tic-tok, fb don't help.

Fb is malware, I don't care who or what's on it, it's off limits. Instagram... no way.
Tweeter just as bad as fb. Full boycott on all that junk until they f-f-fade away
Been using manual brightness control for over a year on my 10+. Occasionally I toggle it on but rarely. Going full brightness will greatly reduce OLEDs finite lifespan. Blue goes first... and the burnout isn't even. If I can get 5 years with just a battery change or two, I want it.
So far between Samsung's and Android's weak offerings I have zero incentive to upgrade hardware or firmware

Yes but if you are using them in tge browser they cant suck your battery up and im only using them for roughly 10minutes a day so no problem. But youre right they are like malware... Traking your location every few minutes and that ****

I do 20-30% charges throughout the day.
Crap like Twitter and fb can cost you your job as well as privacy leading you open to attacks of all kinds. Zero rewards and lots of risk. No.
Remember the night of the long knives?
Think how much easier it be to do now...
Has there been testing on the battery effect of different wireless network modes, including while being connected to Wi-Fi?
I understand that 5G uses more battery, but I'm curious how that is affected when you remain connected to Wi-Fi for all data transfers (using 5G just for calls and texts).
Same question for the other network modes, like LTE/3G/2G vs LTE/2G etc. Or also when you are not connected to Wi-Fi.
I can't help worry that some people are getting bad battery life because they have a poor network signal?
Only rough but very little difference between 4g and WiFi when still, and that's in a location with 2 bars signal. Seems like the phone sleeps better with mobile data on.
It's hard to make a direct comparison with WiFi Vs network, as a lot of the network drain is when moving and polling for new antenna. When looking at signal strength, 4g/5g have the same dBm and 3g/2g have the same dBm, but 4g needs less dBm for a higher transfer rate than 3g, so may use less power over time.
Also I don't think 5g is inherently more power hungry than 4g (I may be wrong), again it's just less available and shorter radio waves, and until now 5g has relied on external modems.
Exactly, I wonder if our S21 Ultra is much better with battery life on 5G, because our SoC includes the 5G modem and it's not external?
My desire is to just keep my phone on 5G while I'm at home idle and the phone is connected to home Wi-Fi. I wonder if there is a battery savings to be had if I switch to LTE while I'm at home on Wi-Fi and the phone is just idle.
