I'm using AOKP (4.1.2) and I really love the rom itself, but I got the feeling that my battery is drained more when screen is on than usual.
With screen off I get good battery life - like 0.5 - 1% battery loss per hour with the standard samsung battery.
But when I surf over wifi for like 15 minutes the battery is drained like 10%. (I always use lowest brightness setting)
I know that the screen really eats through the battery, but this still seems rather high, doesn't it?

Welcome to Jelly Bean. :highfive:
That could be it - so far all jellybean roms I tested seemed to drain more power with screen on than ics or gb ever did.
And my problem is not related to no deep sleep or something keeping cpu alive - when screen is off everything feels normal.
I have reverted to rocket rom v12 cause that... JB is nice but this battery leak is not acceptable for me. Rr v12 is best solution definitelly.

What I found out so far: auto-rotate on is a battery drainer - with it on system_server constantly stays at like 5-10% cpu usage, android.system.ui also uses more CPU % with auto-rotate on, CONSTANTLY.
I've read this is due to a too short polling interval for the location sensors, if someone knows how to change that please let me know, but I'm also trying myself.
Use BetterBatteryStats, my friend, to check if there's a wakelock with some app.
battery drain
i am watching this thread, because i also encountered battery drain on JB. thought battery is gone. hence bought a new one. slightly better but still drains a lot. i think the battery drain is because of smart stay. smart stay uses front camera to decide whether you are looking at screen. so when screen is on, front camera is also on and hence the double drain. at least for last four hours, battery drain is in check, after i turned off smart stay. hope this is right and help all of you.
I have the same issue.. Infact I believe this damaged my Battery.. it was working fine until I was on Stock ICS. After I flashed JB LSZ, I noticed heavy battery drain as well as wierd battery status indications..
Just today I noticed that the battery is slightly bulged..
it might just be the wrong time, or something with the ROM..
my phone is just 15 months old now.
Well to be honest my battery life is "ok" - I do get like 1-2 days depending on usage. As I already said, when the phone is in standby mode it drains very few power like it should. (I do have flight mode on almost all the time too, because I don't use it as a phone, just for data when I need it)
But I got this feeling that the battery drains alot faster than I was used to on screen on time since I'm on jellybean. The thing is, that I've checked almost anything, with BetterBatterystats, BatteryMonitor Widget and Powertutor.
The drainers when screen is on are #1 the Screen and #2 Android-System using the CPU. I've already deactivated auto-rotate and the media-scanner, this helped a bit. The only process that's really showing up in System Load is "android.system.ui" at like 2-5% CPU.
Is this jellybean-wide or could this be due to the additional AOKP tweaks?
How can I break it further down to find what really causes the load? (beside Screen taking more energy on JB which would make no sense from a physical viewpoint, the cpu-usage of android.system.ui can only be the other cause of the battery drain right?)

I am concerned about the battery life of my exchanged tab. The first tab I had has great battery life but had some sound issues that's why I replace it. But now I have this new tab but battery is draing fast even not using heavily. I am charging the tab whole night. I did not even has email account setup so its not retrieving any emails. Any suggestions to improve battery life please?
Is your wifi and GPS running at all times?
If you have rooted the tab try using an overclock tool to reduce the load, this should increase the battery life. Until then we are gonna have to wait for a custom honeycomb ROM that increases battery life. If its as bad as you say it is I would try another tablet and hope you dont get another thats messed up.
GL
No the tablet is not rooted but its factory unlocked. How do I know if the tablet is rooted?
It would only be rooted if you rooted it
Mine barely drains with screen off and Wifi on with everything syncing at the same time.. I can go like 2 days average use on my tab so far.
so it seems like there is an hardware issue. Diversion is your tab unlocked or locked?

I have different battery experience than the OP. I keep my wifi on constantly. On standby with little use (~0.5 hour today), the battery went from 100% to 93% since morning to midnight.
I think it's your unit. I use mine for about a total of 4 to 5 hours a day with wifi and bt at a fixed 75% brightness and when it goes into standby I only lose about 1% every 2 hours. Usually by the end of the day I'm at about 70% battery with a low of 50%.

Have you checked the battery usage to see if any apps are using a lot of battery? (Settings -> About Tablet -> Battery Use)
Mine was at 98% when I went to bed last night and at 94% about 7 hours later this morning. That's with wifi, bluetooth and GPS on, and GMail syncing (but not much else).
all of you guys whose battery has no issue do you guys have tab with locked or unlocked boot-loader. Mine is unlocked and i think because of that battery is discharging fast. Snoopstah i check the settings battery use is screen, browser (which is closed), wifi, android OS thats about it. Please let me know what should i do i have one more day to exchange it.
Thank you all
Exchange it. The battery life in standby mode is stellar. Mine's unlocked too and I lose 2% all night with everything on.
The bootloader on mine is unlocked, and came that way. In either case, that should not affect battery life, though I could imagine how rooting would possibly allow you to install or turn on something that would drain your battery faster (and is left off by default).
Just as an aside, what brightness setting do you guys use on your tabs? Somebody mentioned 75% and that seems super bright to me. I keep my brightness at around 20% or so. Auto brightness is way too dim on this thing. I look forward to some development action on this thing, the ability to customize the auto-brightness levels in CM7 on my Captivate is really awesome.
I have the same battery draining. I can only get 6 hours of straight usage with 20 on brightness. I'll exchange mine today. My zoom can last 8 hours straight of usage

I have no battery issue when in stand by mode and my tab is unlocked and the wifi policy is set to stay on. I drain about 3% per 7 hrs which is excellent.
I don't know if it's my imagination, but since the 2.4.6 update, my battery life has dropped a bit. By the time I get into my office from my morning commute, I'm anywhere in the 65-70% battery life after unplugging from a full charge. I haven't done anything new. I always unplug around 8:30 am when I head out, I do some light chatting with gf, browse some sites, check facebook (usually very briefly), and maybe sometimes do a little reading on my device. By the time I get into the office around 9:30 or 10 AM, I'm usually around the 80-85% area with battery.
Lately, doing the same thing, I'm seeing the aforementioned 65-70%.
Is anyone else experiencing decreased battery life since 2.3.6?
I'm on a Tmobile Nexus S, running stock 2.3.6 (no custom ROMs).
2.4.6 ? .... maybe 2.3.6 ... and yes, I also noticed a slight increase in power consuption after the upgrade. The stand-by is still great .. about 0.8 - 1% per hour.
Sorry, yes I meant 2.3.6.
Thanks for replying Ro_explorer. Is your increased power consumption significant? Seeing 65-70% when I'm used to seeing 80-85% as I get into my office, I find, is a large change. To be frank, the battery life of the Nexus S in general isn't so fantastic to begin with... this hit makes it worse.
Anyone else?
I used to get home with about 40-50% after a whole "normal day" (unplugged at 8AM, and getting back home at ~8PM) .. now (with the same average usage) I'm getting home with ~30-40% ... that why I said "slight increase" ...
Not your imagination, I too have noticed this. I hope the next update, will fix this - as I used to get pretty good battery life (even with over 250 apps).
When I recently updated to the 2.3.6, it caused a bug of continuous reboot (every 1-3 minutes), so I had to do a hard reset - now it works fine, but I only have added back about 15 apps - and the battery life sux!
Downgrade OS' it will be ok.
This is so weird. Why is the battery life worse?

You want bad battery life? Try an Evo 4g with a Sense rom. I averaged about 6hrs using a 1500mAh battery, in stock form.
The nexus is pretty light on power consumption, if you ask me. I average 15hrs on the stock 2.3.7 rom/kernel combo, with stock battery.

I'm on 2.3.6 and need to charge every two days. I text a lot and do light gaming. I'm typing this from my phone. Maybe you could drain the battery and wipe battery stats? I'm not even at 50% yet and I charged yesterday.

I've been waiting to see if anybody else reporting this issue
i noticed a decent increase in battery life going to 2.3.7 and thought that previously the battery life had been fairly poor :\
I am non rooted, and get around 20 hrs on light to moderate use. Again. Stock, non rooted.
How do I recalibrate my battery? I wonder if it could be that...
There are many was to recalibrate. Some involve wiping batt stats, some plugging and unplugging phone several times after charge.
I have always found that using the battery almost all the way down, but not past 5%, and then full recharge conditions it very well.
Oh I've been here to solve the problem
"Why last 2 weeks my Nexus s drain battery so fast ? or I have to calibrate it"
Thank for your notice about update OS to 2.3.6.
I think that's a root cause for me too.
1. Could I rollback to 2.3.4 ,how?
2. Does battery calibration is useful for this case , how?( someone suggest to calibrate when flashing new rom )
Thank you very much..
i want to know who have some methods to do with this stuff

Whenever switching roms, kernels, or batteries, i always perform the following :
1. Charge to a true 100% (Battery Monitor Widget will register +0 to +2 mA)
2. Wipe battery stats using recovery (Amon RA has this option for the Evo, not sure about cwm), Battery Monitor Widget, or a dedicated app.
3. Discharge battery to 0% with normal usage. When the phone shuts down, I pull and re-install the battery and power back up (it will shutdown again very quickly).
4. Recharge battery and be on my merry way.

I found one workaround solution for this issue on
ww.google.com/support/forum/p/Google+Mobile/thread?tid=1684c50cea15282a&hl=en&fid=1684c50cea15282a0004af022e5ed212
Sproogle77 's solution
Problem solved. Using the OS Monitor app, I found that the main culprit was Google Services - the Contacts sync specifically. Even though I had this disabled (only Gmail was being allowed to sync) it was constantly working, apparently trying to fix a location. The message log showed that it was generating continuous debug messages, all about locations - around 10 of these every second.
I have solved the problem by disabling 'Use wireless networks' under the Locations & Security settings.'Use GPS satellites' is still running. This immediately dropped my CPU usage - which had been running around 30 to 40% even when otherwise idle, to around 10%. Google contacts sync is now using 0% of the CPU. The difference in battery life was pretty much immediate and is now back to what it was before - the change in the slope on the battery usage graph is remarkable!
This doesn't really seem like a solution to me, and I don't know whether other aspects of my functionality are being affected, but at least my phone is properly useable again.
I'm testing for 1 day and I think that's working for me.

One reason is that the new version of the stock kernel removed a speed stepping, so it'll power to higher levels faster, thus using more battery.

That actually isn't the problem. I'm using netarchy's kernel and still get this problem.
My battery life dropped from 16 hours --> 6 hours. the slope on my battery usage life is horrible the system is also awake almost constantly even when I'm not touching it / getting no messages.
I will try the fix suggested on the google support forum and see if that does the trick. sloppy update.
I apologize if this was asked before (I did a search of the forums but nothing really came up), but I'm wondering what others' experience with the battery life of the S4 is? This is my first smart phone and coming from a non-smartphone, I'm not sure if my expectations on battery life are unrealistic.
I got the S4 on 4/29 and brought it through one full charge cycle and several part cycles. Battery life is pretty important to me so I put an all black background (since its AMOLED), keep the brightness to below 10%, turn off all the fancy sensor things, turned on power saver mode, turn off wifi and data unless I really need to use it, turn off all sync so it only happens manually, etc. Yesterday, I charged it to 100% to see how long it would last and the stats I got were:
At 6% battery left, I had a total screen on-time of 2 hours and 58 mins and 1 d 2 hr on battery. Then, when I charged it to 100% and took out the charger, after about 5 minutes of it sleeping/screen off, the battery percentage dropped down to 97% with no data, no wifi, no active apps running.
With my pretty battery-friendly settings on my phone (or at least I think so), is this battery stat normal to others with this phone? Or do you think something might be wrong with the battery?
That sound horrible. There must be some rogue apps running/some wakelocks - try using better battery stats and find out.

For a smartphone, an 'all-day' battery is fine, and given that the S4 has so many sensors, large screen and a powerful processor, I am happy with the battery lasting for 12-16 hours. I don't turn off any sensors, why get an S4 to run it on power saver mode and turn everything off? It defeats the purpose, in my opinion. I am trying to use as many features as possible on my S4. Of course, there are a few I don't, but just for personal preference. What you are doing is (no offence) in my opinion like getting a BMW M3 and running it on 4 pistons to save fuel.
Anyway, your battery life will improve after about 10-15 charge cycles, I noticed that with my past phones as well. If you need your battery to last longer, I would suggest getting a spare battery and keep it charged at all times for any emergencies. These are some of the reasons I love Samsung, removable batteries and microSD card slot.
thanks for the replies guys. I'll try the betterbatterystats app out. i'll probably take it back to sprint and see if they'll replace the battery for me. the screen accounts for about 50% of the battery usage in the stats and other apps take up the rest. the battery curve is pretty linear in a downward slope too (except when i don't use it at night, it becomes much flatter, albeit still downward).
haha its funny you say that, because i agree completely. the m3 is my dream car and if i could ever afford one, i would probably baby the crap out of it the reason why i got the s4 (and i also compared it to the htc one as a possible candidate) is because of the removable battery, sd card, nd most importantly: camera. that 13 megapixel shooter + hdr is really great for good photos on the go. speaking of which, i use the camera alot. is the physical use of the camera and the screen use a big power hog?

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.

Hi,
I have an LG G2 (for more than 18 months) which I really like (and still can't find a compact 5-5.2" smartphone to replace it with) but it seems that lately the battery drains quite fast when having the screen on.
Brightness is set at Auto + 50%, as always. The drain seems to be around 1% per 2 minutes. Screen is reported to consume about 50% of the battery. I don't think it would last more than 1.5-2 hours untill the battery drains completely. I noticed others getting like 4-6 hours of screen time.
I performed a factory reset and things look better overall but as soon as I use the screen the accelerated battery drain starts. I am using the 30b lollipop update, phone is 100% stock, no root.
Is this considered normal ? Should I attempt to replace the battery ? Is 18 month too much for it ?
Thanks !
Turn off the wifi when you are not using it. Whenever my wifi is on and connected my battery drains like crazy.
And i am rooted with exposed and power nap.
After i turn off my wifi my battery isnt draining at all.
