my battery does not drain my opinion.
So your battery goes from 100% to 0% in a little over 3 hours? You need a new battery.

Nah man it was fine before.. just after this rom its dying like crazy, its not as bad as 100-0 in 3 hrs tho.

every once in a while I stumble on a Rom / Kernel combination that does this. It could also be a rouge app that is being reported as system.
Try this: install OSMonitor (because the system doesnt give you specific details) and in the setting have it sort by load, then find out what is taking the most percentage of CPU. Long press on that item and select Watch Log. See if there are errors or redundant messages that keep popping up. That will find your issue.

hey man thats very helpfull, thanks so much..LOl but i just flashed back to evils sense rom.. so lemem see if this is consistent. Thanks man.

I get great battery using miui ROM with kernal 2.6.35.4 [email protected]#12. ALSO let battery drain completely and charge fully without turning it on. Then boot to recovery and wipe battery stats. Conditioning and the right kernal / ROM combo has my battery holding up great! Hope it helps! =D

+1, with setcpu

I'd suggest you try CM6 and SetCPU. Both have dramatically helped increase battery life for my N1. I never used to get one whole day's worth backup before, but now I do, sometimes a little more than 24hours (when not used quite a lot).

For me, I found the biggest battery drain to be signal strength.. Even more so than 3G/WiFi or brightness. In an area with low cell signal, the antenna seems to be constantly trying to reconnect and it kills my battery life in a couple hours. If im in an area with strong signal, I can leave everything on (gps, wifi, bt, 3g) and get all day service easily.

Poor battery life after P6800XXLQ2 Flash.

I flashed P6800XXLQ2 everything is butter smooth and rock solid stable, but... it chews battery like crazy when it idles.
I had 30% batt, locked it and went to sleep. This morning I found it dead. If you look at the battery curve it always goes down at almost the same slope, does not matter you use it, or not.
EDIT
I tried wiping battery stats and disabling WiFi wile locked. Still the same.

I follow below suggestion and it seems to work.

I had the same issue having my WiFi off. I had to turn it On and then Tablet started working for days just as before
Turn on - for longer battery life, weird, but that works

So which of these I should chose?
Keep Wi-Fi on during sleep if you turn this off it’ll help extend your battery’s life when the device is put into sleep mode.

Always.

OH WOW! Last night I disabled WIFI & Mobile data and locked my device. It had 59% battery. Now it's 58%!!! After 10 hours. There are some serious problems with LQ2 power management.
It aways goes down this straight slope. Does not matter if I use my tab at all. But last night?
So phase 2 of my test, I will use WIFI only, and no mobile data.

some times this happened to me also ... and then I noticed because some application still active in the background eg game and youtube internet browser. even after I quit .
I did experience also my galaxy tab 7.7 was warm /hot ... this was because the game and internet browser still active in the background.
So after that I always "closed all applications" from "task manager" ... no more battery issue or warm /hot issue again.

OK I have disabled mobile data entire day and set to disable wifi when locked. My tab was almost unused all day and this happened.
IT IS WIFI RELATED!

S4 high battery consumption

hi guys,
im troubleshooting my battery problem on this phone. just need some thoughts.
the drain is over 2%/hr when the phone is in sleep with flight mode on and nfc on.

the day before i tried this with the network on nfc on, data and wifi off and the consumption was about the same.
i have yet to try flight mode on and nfc off, but i wouldn't think that nfc would use that much.
i use greenify to put a lot of apps to hibernate so they wont wake the phone.
starting to think my battery isnt performing right anymore.

17% in 6.5hrs, airplane mode, no nfc.
the phone is definitely going to sleep.
i could leave the network on and nfc too, difference isnt big at all.
any idea is appreciated. leaning towards bad battery here..

Why not remove all the extra apps, and see if anything changes. Then, you can install one by one when things are clearer.

i would believe if an app cause the drain with the screen off then it is probably causing a wake lock.
which doesnt show at all. is there any otherway an app can drain the battery without wakelock?

I don't really see drain? 2% an hour is not that much. In my opinion it's normal.
If you insist on lowering it, then try the following:
- Different rom
- Different modem
- New battery
And search for some guides to lower your battery usage.
You have to experiment yourself.

it didnt use that much before. in 15 hrs i got a bit over an hour screen time before it hit 0.
anyway, just loaded romswitcher, going to see if it happens with CM too. and airplane mode on.
starting to think the battery is going bad already

I average about 0.5% drain during sleep.
See the link in my signature to find out how. I've got a whole guide.

Have you checked the serial number on your battery? If it starts with BD then it's stuffed Samsung should still swap it for free I think.

thanks for all the replies guys.
yes 0.5 drain should be normal when it sleeps.
just tried this using CM rom and it looks all good there, so its not the battery.
going to remove some experimental settings in greenify to see if that helps.

Abnormal battery life

I purchased my 6P roughly 2 weeks ago and I'm not seeing this amazing battery life of everyone else's.. The best I've gotten was 4hrs screen on time with 25% battery remaining. I've tried tons of ROM and kernel combinations, as well as being on stock with locked bootloader, the battery life seems worse with kernels, and the same with stock based Roms. Below is my current SOT with stock rooted, stock kernel. Is there something wrong with my battery? Considering calling huawei for a new battery? This is pretty **** battery. My galaxy S5 had better. I constantly check my CPU States, it does deep sleep perfectly fine. No abnormal wakelocks, I don't even have Facebook installed. The 4 hr SOT I did achieve was with greenify and amplify, which I don't think I need for a phone with this kind of battery...

Depends on a few things. Could be a rogue app, wifi wakelock, or really poor signal.
You could try stock and no apps for a day and see how it performs then.

the apps i use are twitter, whatsapp, tapatalk, slide for reddit, snapchat, instagram, open camera, and neko atsume. thats pretty much it. Of course cpu spy for monitoring, and sometimes i do notice wifi taking up a bit of battery, but even if i disable it and it goes away, the battery life is still poor. I have a moto 360 and I usually have it paired via bluetooth. I also use google now but i set the GPS mode to either device only or battery saving mode. reverting to bone stock google images locked bootloader to see if it makes a difference, again.. even if the wifi isnt draining.. still is poor. I did monitor my signal and i get very good LTE signal all over my city, so I can rule that out. Would huawei honour this request? I am located in Canada if it matters. Also i dont think its app related because i use the same apps on my S5 and the battery is better on it, which doesnt make sense.

Have you tried turning off WiFi scanning and Bluetooth scanning? They're pretty much useless but consumes battery.
Go to Settings > Location > Menu > Scanning > toggle both settings off

Yes I have, as practice I never have them enabled.

So I have had my phone on for two days now and charged back to 100 of course. Total screen on time over that period is 3 hrs.. This is brutal. Phones at 58% right now. I'm noticing this (screen shot) is this the culprit and does huawei do warranty in Canada?

Nexus 6p google app battery drain! Wtf

What the heck. I'm on pure nexus , custom elementalx kernel and some tweaks here and there , and this afternoon I was driving of the highway and felt that my phone was getting a bit hot , as if it was on. Looked at the screen and nothing , it was off , nothing was running. After like , 1 hours , I came back home , looked at my phone and the battery was like on 30% , when I was previously on 50 some .. Just look at this graphic and tell me what you think of this. I force stopped the app from running , cleaned the cache and data. What's going on with Google app ?

Go into Settings / Accounts / Google and see if it shows any sync errors. You also might want to disable sync for any services that you don't use.

I have the same problem with the recent 7.1.2 beta update. The phone doesn't last for more than 4 hours in idle (stand by) state.

Ok, do you know what is draining your battery...Google App? On my phone in just over 6 hours Google App has only used 1% battery, calculated at 20 mAh. Assuming you have a known good battery (eg. capacity >85%) it may be time for a factory reset? If you don't know what state your battery is in, try running Accubattery for a few days to get an estimated capacity of the battery vs. design. I'm running 7.1.2 Beta 2 and only losing 0.3%/hour (standby overnight) per BBS. Lost 3% battery last night over 9 hours. Stock ROM, rooted, EX kernel. My battery shows 97% capacity using Accubattery.

I had very poor battery life on 7.1.2 on the stock kernel unrooted and ended up rooting and going back to a custom Rom and kernel. I don't suppose you checked the stock kernel settings before flashing ExKernel? Stock based Roms based on the latest Google images have been reporting bad battery drain. I think Google has started using default kernel settings that are causing battery drain and if you aren't rooted and using a custom kernel there's nothing you can do about it.

I have no battery problem after flashing factory 7.1.2 DP2 including factory reset. Quite the opposite actually. All sync, backup, high precision localisation, Google photos , etc.. enabled. And most of the time on 3G or LTE.
