my galaxy nexus's screen is draining to much battery

hey.
i bought a new one like 3 days ago, rooted and installed android revolution HD custom ROM.
which says makes the battery better and has a custom kernel so im not overclocking my processor or anything.
i even fully charged to 100% and wiped all battery stats with CWM.
on my battery stats page it says my screen is using 50% of my battery and when i press it it says its been on for 2 hours ( out of the 14 hours my phone has been since i charged it )
thats too much battery drainage going on here.
any help ? or suggestions ?
oh i also have my wifi on and my screen brightness set to the lowest possible

This is normal just read over threads....

You never mentioned what your final battery level was after 14 hours and 2 hours of screen? The "50% used" means 50% of the battery used to that point.
FWIW, I'm showing the following at the moment:
78% battery remaining
3h 51m on battery
Screen: 62%, Android OS: 17%
Screen on time: 1h 17m
So, based on this, I'd expect to get maybe 15-20 hours of charge and 4-5 hours of screen use out of a full battery, which is about right.
Daern

Battery life of a brand new device is always going to be a little poor.
Here's what I do: Charge it up all the way when you first get it. Then run it down until you get the low battery warning. Then charge it up. Then use it normally.
After a week or so, your battery life will normalize and should be much better than the first couple days.

alright
i will wait until its on 5% or so and charge it to full again.
my battery is on 48% now after 14hours of use
2 hours screen ( 51% screen usage )
android os 15%
notice that im running with the minimum screen brightness which is not what i want to be on most of the time =/
but i have wifi on AT ALL TIMES, it doesnt drain as much battery as the screen.
anyway i will wait for the battery to normalize like one of the users said and see what happens.
thanks a lot

it's normal for android phones or any phones for that matter.

48% remaining after 14 hours, with 2 hours screen on is pretty good actually, especially if you have had the phone under a week.
You will find the battery get better after half a dozen charges
Remember, its a 4.6inch screen with hd resolution, that's a big hi res screen by any stretch, and will use a bit of power

The ARHD ROM is a good one, and you'll get excellent battery performace, especially if use with the James Bond kernel and undervolting settings. But to lower your screen battery drain, use a dark (or plain black) static wallpaper and auto brightness.

standard nexus , no rom kernel or GPS and Bluetooth, twitter Facebook and Gmail set to push. Playing games and listening to music , brightness 100%.

It's a 4.65" 720p for science's sake... based on your stats, you would get 4 hours of screen on time from a total of 28h on. What did you expect ? 10 hours of screen on time ? Sheesh... Where did you come from ? iCrap ?

Dunno, for me GSam says that the turned off screen takes almost 4 times more than turned on. I know how it sounds, but having screen drain about 20% from all, though it worked for 20 minutes of 2 days. And the common battery life if not too bad - about 20% per day. I cannot find the reason for already three weeks, how this could be?..

When you have drain like me then you can complain . I have yet to figure out why my battery drains so fast, it ranges from 10-15% an hr while its just sitting there.

ie: if it says that the screen is draining it 50%, it means that 50% of the power drain on the battery was caused by the screen, it didn't drain your battery by 50%. The screen is the biggest power hog on most smart phones so your stats seem pretty normal.

Well, the drain is not big indeed Just to ensure, that it could happen at all and find out, what it could be - kind of perfrctionism
Just installed PGM, assuming it will change the statistics. Let us see how much.
OK, after maybe a day with PGM I should say the drain is same - about 1.5% per hour (with radio turned on). Trying to be more tolerant to drain now

Battery Stats Thread

So I was wondering if anyone who has their device already could post some screenshots of their battery usage, screen time etc?
I know there have been some thrown around numerous thread but just thought it would be useful if people would post in one place?
Thanks

just wanna share some battery life stats..
1st power up of the phone.. did a full charge with phone off, once charging light changed to green, i powered up the phone.. 1st thing i notice.. it is not fully charged to 100%..
next thing to take note, the entire duration the phone is on is an additional hr plus.. i rebooted the phone once so im not sure what is the actual duration the phone is powered by the battery..
all in all, about 3hr+ with high usage of the phone.. notice how the phone was awake most of the time and the screen was on most of the time too..
cheers..

Only if this phone had some decent battery packed in, as in the Note, I'd have grabbed it. Why HTC why ?

Screenshots ain't working.

Is it true that there was yesterday a OTA to fix battery issues?!?! If yes, did it solve? and what is the version number?

These are my stats from first day...not bad given how much I'm played with it

Whats your screen on time?

1st post so I hope it's helpful.
I'm a big fan of the phone & love it, there are a few small issues I've noticed & I'll post these in the relevant thread.
People keep saying the battery life is dreadful but it doesn't seem much worse than my original Desire on similar use.
After the first full charge last night I plugged in the charger when the warning came on at 9%:
11 hours 2 minutes on battery, screen used 75% of the power while on for 4 hours 31 minutes.
Everything else used a few % each.
Brightness was on auto at approx 50% most of the time and on full for about half an hour; indoors I wouldn't want it as bright as that.

Hi
Thinking about this phone or the one s. Just a quick q regarding the documented poor battery. Could i go out for the day - say for 15/16 hours send the occasional texts maybe a couple of photos/videos and the occasionally browsing the web - to check football scores etc etc.. should this handle that ok ?
is a pocket charger the way to go ?

That's how I intend to use the phone tomorrow, so i'll soon let you know.
The thing with this phone that is superb, there is hardly any drain when your not using it. It's extremely good for idle power saving.

dunno about you guys but i'm getting insane numbers in standby...
overnight i lose 1% with wifi, data and autos-sync on....
it's the first android phone that sleeps properly when screen is off...there's nothing keeping it awake.
i'm on 1.26 by the way

Well I don't think it's that bad on battery given how much screen time i've had....three and a half hours.
Only got 2% left so going to put it back on charge. These are my final stats for my first day after a 13hour charge

Mass battery drain?

So I'm on 4.4.2 stock, Stock kernel, and I'm getting ridiculous battery drain. Any app I use, I will use for 5 minutes and lose 10% battery. Had 100 and then to 72 in a matter of 20ish minutes. And then as I'm typing this I plug it in and it jumps from 72 to 18?! Anyone know what the f is going on????

I had to same issue, I use this app on the play store called battery doctor (battery saver) its very well saves me battery,
Now there's a test you can do yourself to see if ur battery is bad or going back one is see if the little white sticker us still white if its pink it came into contact with water, another thing you can do is sit the batter flat on a table and spin it if it spins by itself( try on both sides) that means the battery is fattening up and needs to be replaced. Or if u want to you can take ur phone to sprint store and have them test the battery. You just say I need my battery tested I think it's bad. And they will do it for you I used to work for sprint. Now if u need another battery the stock battery is Samsung and you can get it cheap on Amazon.

Halp. I got a new battery, the anker 2200 mah, and I'm having issues again.. Charged all night, within 20 minutes of unplug I'm at 63 percent, then I plug back in to charge and I drop to 23???

It's definitely gotta be TouchWiz (if you're still using it). I have a backup of it via TWRP and I use it when I have ST network issues. When I flashed CM11 and spent a few nights charging and using it through the day, it got used to me using it. I don't know why, TouchWiz just has too much battery usage.

try doing a battery reset once you have the new battery in...

TouchWiz drained my battery so I could only get about 4 hours out of it. I have PacROM which is stripped down more than touchwiz+slim Gapps, and I (attempted to) enable battery tweaks but it didn't want to stay checked. I usually have my brightness down all the way and use Advanced Task Killer to kill my apps.
I remember when I used to use that on my LG Optimus S. Good days...

My battery is also doing this but then i question which is the true percentage...so then i quickly take the charger out and its just drops in a minute so i know if it thinks its dead its dead.

I would hope so as my device is 3 month old and im guessing ur device isnt that old...it would be horrible if batterys were going wrong that fast...no i would say its got something to do with the device judging the level incorrectly fo whatever reason and your idea of calibration is the right direction....i think im going to try as couple of suggestions in that link myself tbh.....if ur battery was to be lasting like an hour though then i would say somethings not quite right.

I just got in on monday this week, the battery usually last for about a day with 3-4 hours of screen on time with reading and web browsing, with a bit of gaming which seems to kill it pretty fast. I am currently let it charge overnight and the do a full charge cycle to see what will happen. Thanks for your help :good:

My battery jumped when I was playing clash of clans when my battery was at 10%. It went from 10% to 3%. So then I rebooted and it went back up to 5%. So when my battery was almost dead.. I quickly resetted the fuel gauge in synapse.. And waited a few minutes then it died. Then I plugged it into the charger (did not touch it) till it reached 100%. Seems to be fixed now I hope.

The battery seems not to handle gaming very well i think, those drop are from playing brave frontier am still currently sitting at 38%

I bought this tablet 3-4 days ago. I installed this warship game. I also noticed that it literaly jumps from 30% to 3% in just 5 minutes or less. But my battery charges very quick,which is good on the other hand. What is going on whit this tablets battery? My tablet is still stock,not rooted and bla bla... LTE version offcourse. I'm not sure,but i think it started draining the vattery as soon as i insrted the memory card.

That's the problem I had on me T700, thank God I don't have this issue on the T807.
Funny thing, when the T700 battery died, I'd turn it on after 3 min and would show battery at 23% again and I was able to use it for another 15 min or so

I also had the battery problem,too.
After three days suffering by test all the method I Google from internet, I return my T705y to samsung,and they replace the board and battery.
Now everything's fine, try it,just return tabs to samsung.

tab s 8.4 lte battery only shows 2100 mah fully charged
I purchased a new oem battery (4900 mah) and put that in and it is still showing capacity for the battery as 2100 mah...have not a clue what is wrong?

Question Battery Usage pattern in Moto G 40 Fusion.

Battery usage patter here in Moto G 40 Fusion is very confusing. As U can see it clearly that the Device got charged fully (100%) 5 days ago & it's giving a usage pattern of total 5 days as a whole. Is it normal?? I mean I have had my experience with Moto E, Moto Z2 play but didn't face such wired issue.
So my queries are as follows;
How can I get refreshed usage pattern after every recharge cycle?
Is it still calibrating? Do I need to wait for 1-2 more weeks to have a meaningful usage pattern?
How do I know of those Apps & Settings, using battery after every recharge cycle?
Is it some kind of bug or Android 11/ Moto G limitations?
If everything's normal then why do we need such meaningless & useless battery usage status?
Need help.

Sorry I didn't understand....
Are U telling me to charge my phone to 100% ??
I don't charge phone to 100% only to preserve battery life. 80-85% charging is enough to give me a full day battery back up but here comes the main issue. Charging to 85% won't trigger a refreshed app list (battery usage list). Refreshed battery usage mean a fresh list of apps consuming battery after every recharge. I hope now u'll get my point.
Otherwise u won't be able to find which apps n settings are taking the battery juice within a charging cycle, no matter if u charge it to 40%, 80% or more, U must know ur usage pattern.

I have another feature for you to be discovered
It works at night hours only (anytime after 10:00 pm I guess)
ENABLE "battery overcharge protection" and "optimized charging" from Battery settings
Set an alarm for the morning
a few minutes later
Plugin the phone to charging
You will receive a notification that your mobile will be charged to 100 % by the time alarm wakes you up

You'll have 80% charge left after the drain and keep on draining based on app usage.
