OH~~!!!!
anyone have solution???
pls !!!!
(i am not to hate that)
What apps are actually running in background of your phone? I have only a 20~30% drop in battery level in ~9hr without touching my phone(wifi on).
see what the battery life is like if you turn off the killbacklight app for a day
i only open the backlight killer in background
nothings else
There's nothing you can do at the moment, unless someone fix this nasty bug.
You have to know that Android saves battery switching off your CPU while you are not using the phone (=> deep sleep). The app you are using "kills" the backlight every X seconds, that means your CPU is awakened every X seconds to execute something.
Your screen always on uses more battery than your CPU always on, I think, but it always drains the battery.
Use" ddkp3" as the bottom package will be more power, I tried
I have a Mi2S and I'm running the latest stock ROM 4.4.23.
Ever since the 4.4.11 update I've had poor idle battery life.
Before that when I look at my battery usage, as long as I have good signal and the screen is off, the battery level graph is flat.
Now, almost always when my phone is idle, no matter what there is some heavy drain, it was approximately 25% over 12 hours.
I've tried all the MI2S updates since then and they are all having this issue. I have not installed any new apps or changed anything on my current ones.
Attached are some wakelock detector screenshots.
Sometimes 小米服務 has many wake alerts, but sometimes it does not. Weather app is disabled, and autosync is disabled too. Occasionally 小米服務 does not have many wake alerts but that doesn't seem to reduce idle power draw, and I think it had this many wakes before as well.
Also the 3h wakelock app is the music player; the idle drain happened when the music player was off.
Thanks for reading.
Bump...
So I spent a night in airplane mode, and voila! 3% drain over about 12 hours!
I'm still trying to figure out exactly what it is, but whenever I get the chance to I'm going to spend another night in airplane mode with wifi on.
Bump...
There is a nice little utility app called power tutor, which shows you exactly which app drains your device. Maybe the problem isn't rom related...
You can find it on the play store.
Hi,
I have a question regarding battery life of the OPO. I'm still not sure whether I have a defective battery, or some apps drains my battery like crazy (or both?). I hope you can help me with this.
In the first 2 weeks since I got it, I use my OPO for mid to heavy activities (a lot of Whatsapp, Youtube, streaming music, etc). I always start the day with 100% battery and I thought it was normal to see the battery drops to at least 20% at the end of the day. To be honest, I didn't check the battery stats in Settings even once in this time frame, and due to my heavy usage, once again I thought this was normal.
Until one night I decided to plug the charger earlier than usual, unplug it around 11pm (w/ 100% battery), then I fell asleep. I was shocked the next morning (8am) when I saw the battery has decreased to 65% with no activities whatsoever. I check the battery usage in Settings and then saw Google Play Services (GPservice) at the top of the list with 45% usage, with "keep awake" time almost identical to total time on battery. I did some research and found some advice including 1) denying GPservice abilities to "keep awake" and "wake up" via privacy guard (from this thread http://forum.xda-developers.com/oneplus-one/general/guide-google-play-services-battery-t2832525), 2) turn off location, 3) turn off sync, but none of them seems the solution to my problem. Since then, I always check the battery usage and reset it, to see if GPservice still at the top. Sadly it still there. After I reset the stats, go to sleep directly and check it about 1 hour later, GPservice uses 40% - 60% of the battery usage, draining about 6% battery / hour.
With screen on a few minutes, it easily drops to 5th or 6th place with ~7% usage, with screen and main apps I use on the 1st and 2nd place. When I googled about this using Firefox, that's when I start worrying about something else, the battery itself. With wi-fi and low brightness (less than >20% if I convert it from the slide bar), browsing with Firefox decrease the battery 1% in 2-3 minutes, no or low usage drains 1% in about 5-6 minutes. In contrast, charging increase the battery 1% in 1 minute. Is that normal? IDK, usually bad battery increasing faster when charging and decrease significantly when in use.
Please help, especially about the excessive GPservice battery usage. And if it's possible, I prefer non-root solution for it. Thanks and sorry for my bad English.

Definitely sounds like somethings not right, what apps do you have that access or could potentially access your location? If you're still not having any luck, as a last resort you could try a fresh install of CM11S and install your apps one by one to see if you can determine if any are responsible for sucking battery.
Give the below app a try:

Install Gsam to see if you can gain any more insight into whats causing battery drain.

Maps, Google Fit, Google Now, among other things.
CMIIW but I read somewhere that GServicefix does the same like privacy guard, denying some service to keep awake, wake up, etc.
So I installed Gsam and run it about 1 hour. Interestingly in there, Kernel (Android OS) is on the top the % list with 60% usage (mostly phone in idle/sleep). When I switch sorting to Kernel Wakelocks, it shows event0-798 & event2-798 as the top 2 wakelocks with around 7000 wakelocks. I'll update in few hours, thanks.

From what I read on the Play Store description, Kitkat and above requires root?

Hi, sorry for the late reply.
It seems reboot the phone a few times solves the problem. Battery usage now seems normal when idle, even with location & sync turned on.
Let us not imagine a smartphone without battery. Battery is most important part of a smartphone. There is a few cause to drain battery quickly. Like as big LCD display and luscious AMOLED display, and background apps obviously drain your battery quickly. You can do something to make battery for last longer. Let’s see that how to increase battery on your android smartphone.
how save battery life
How android batteries work:
Have you heard that most smartphones have a lithium-polymer either or lithium-ion battery. Both of actually lithium-ion though, and as like, do not have a 'memory', which means that you can charge them from any level – you don't have to fully discharge it before charging it up – and you don't have to charge them all the way to 100 percent.
In fact, lithium-polymer either or lithium-ion types of batteries affected by low voltage problems, so it's actually better to partially charge it (say, from 20 percent to 90 percent) than to fully charge and fully drain tit. Just explore that is it work for you and you can easily increase battery on your Android smartphone.
how save battery life
Using du battery saver apps:
du battery saver is a most powerfully app for save battery.you can use du battery saver for save battery life.for download click here
Black wallpaper can increase battery:
If your phone has an AMOLED display (like as Samsung devices), use a dark-colored wallpaper for background . AMOLED screens only illuminate the colored pixels that’s why Black wallpaper can increase battery life. Black pixels are unlit, so that less power is needed to light them up.
Doze:
With the entrance of Marshmallow came a new feature called Doze, which is helps you get to reduce drain of your battery. , Doze is the most noticeable addition for android Marshmallow. It is allow default and typically permit your device to enter hibernation mode when it has been lock or unused for a long period of time.
Update your apps into latest version:
Keep update your apps with the latest version. The developers constantly update apps for battery and memory optimization. Keeping your apps updated also means you have the best optimizations available
Using Greenify apps:
There are many Android apps that claim that they optimize performance and increase battery life, Greenify is one of them and it’s actually works by preventing them from operating in the background. , which reduces their impact on the system Greenify stops this by sending those apps into hibernation and saving battery life while improving performance.
Reduce auto-brightness:
The screen is a biggest battery drainer. This is one of the best ways to increase your battery life to use auto-brightness manually to a level that is low but comfortable your eyes. And do not use display as auto-brightness mode.
Turn off vibrate and haptic feedback : For save battery turn-off your vibration alerts for incoming call, and turn-of your keyboard vibration and touchpad sound.
Use 'Do Not Disturb' or 'sleep' schedule :
when you are In a meeting , set your device to not ring, vibrate or connect to the internet when you are sleeping you can enable blocking mode to switch off Wi-Fi and mobile data when you don't need them.
For this purpose many phones have a Do Not Disturb setting.
For example you can use airplane mode.
Trun-off unnecessary service:
Whenever you don't need them turn off, Wi-Fi , GPS, Bluetooth, NFC and mobile data,Turning off location. It’s will increase battery on your Android smartphone.
Explore the battery saving features on your phone:
At first Find out the battery saving option in your smartphone and Trun on your bettery saving mode in your android smartphone when you are out of home and not use the phone.
Turn off auto-sync trap:
If you do not need google account update in every 30 minutes, tap into setting to turn-off google account turnoff auto sync and for these app you do not need update. For example email, Facebook, twitter, reddit Instagram etc. just sync when you actually use the app.
I miss something’s? What you have any idea about battery saving tips? Tell me about them in the comments.
I don't, and will never use gapps or any google's apps.
I am experiencing a high and crazy performance using ntfs as androed installation.
I will never burn my money in ext2/3/4 or any ext device.
I will never pay absurds for unrooted phones to rooting only to purge gapps and gogle apps or any other kind of damned apps that stays cooking battery.
My next device, needs be like this screenshot, with ntfs, rooteable, rom choices, or DEATH!
I hate androids.
This is why i preffer write Androed

Ok,
so when the phone reaches 15% and the message saying that i should activate Battery Saver appears, the performance of the phone goes down and the games are not smooth anymore.
I do not activate Battery Saver, but obviously something happens that limits the CPU speed. Can this be deactivated somehow?
Thanks a lot!
Probably lower voltage on battery, hence lower voltage on CPU/GPU and lower boost clocks.
But still, there must be something applied by the OS as the switch happends instantly at 15%. I' m guessing it' s something we don't have access to.
