Hi. Maybe someone can help or explain.
Is it normal, that the CPU drain the battery that much?
Thanks in advance.
Mine is showing 28.3% highest useage as well.
Not worried as I still get 12-14 hours over 2-3 days.

These numbers are pretty much useless IMHO. If you lower your brightness and use internet less you'll get higher percentage in CPU. Download BetterBatteryStats and you'll find much more usefull info there.
Thanks for your answers :good:
Allet normal
On my Lenovo P2 I had a battery drain problem, the phone couldn't go to deep sleep because there was something going in the background. With Cpu Spy I noticed that the CPU was constantly used at 625mhz in standby. At the end I realized that the problem was Root Checker app. Uninstalled immediately, problem solved.

I'm experiencing a very big battery drain when the screen is off for a long time. I just left the phone screen off for 2 hours because I took a nap. When I woke up, the battery went from 60% to 40%. (via Juice Plotter) That was 10%, per hour, while screen off. I did not experience this from the AcesMod v35 original kernel. My SetCPU profile for screenoff was 128-345Mhz, smartass V2. Could this be the problem?
Thanks in advance.
I'll give you the best piece of advice concerning changing CPU frequencies.

Can i ask whats wrong with setcpu then?
A) Android manages it's CPU frequencies absolutely fine by itself.
B) By running SetCPU, it constantly needs to monitor your phone for it's state, so it can change the CPU frequency, which will just use more battery.
C) Overclocking your CPU will kill it faster.
i was hoping somebody had optimal setcpu uv settings. i'm trying to squeeze every last drop from my battery but i really don't know how to set it up. any help would be great.
Read this.
I'm using these settings and my phone lasts for 5 days (no gaming ofc. )
thanks. trying those settings now
Theres no such thing as optimal settings...everyones phone has different tolerances...
Go down in steps of 25 and stress test is the best way...Trail and error.
This belongs in Q&A ...not here
Sent from my GT-I9100 using XDA App
yea i used the settings in the link as a starting point and managed to lower them a little. is it just me or does that 4 days on a charge seem a little too good to be true? the best i can get seems to be around 1.5% of a 1650mah battery per hour in standby. about as good as my hd2 running gbx 12 got. the phone does go into deep sleep (76% since reboot) but i don't get anywhere near the tiny battery drain some do. the setcpu uc and uv adjustments did help some but not as much as i had hoped for, guess i'm just gonna have to get a bigger battery.
i put it here 'cause it was a setcpu question. i know its turning into something else. sorry 'bout that.
Thats because you have wakelocks. In deep sleep, I get a maximum of 5% battery usage over a 10-12h period. Check if some apps are keeping your phone from going into deep sleep.
yea i have quite a few wakelocks but they only are "active?" for a few seconds. k-9 was the biggest culprit but a bunch were system processes. i set k-9 now to not poll but i don't know what do do for the rest.
how do you know if the wakelock is a partial or is locked? do the partial ones keep the phone from sleeping all the time or only when the app/service is active? is there any way to suspend/overide partial wakelocks on a per case basis so email and such can update but still blocking some? i've done a little reading but this seems more complicated than it should be.
I`m not playing games or running CPU demanding apps, just phone calls/sms/bit of non flash web.
Is it possible to downclock CPU to increase usage(save battery)?
Or CPU doesn`t eat that much battery and downclocking would have very little effect on battery?
With a rooted device, you might want to try CPU Master Free. You will be able to decrease the clock speed.
Also, you could try to UnderVolt your CPU. Search for your phone model UV in te forums.
Min frequency is 350MHz so if your not doing anything it will be idling at 350mhz

It does help you save precious battery life.
You can download the best app for overclock, SetCpu, from the XDA site, it's free for XDA members:

How much more battery life I could get by downclocking CPU? Any feedback from people who have tried such thing?
On my gn i find the screen to be the biggest user of thr battery power so underclocking prob would have little use, ohh and iirc the phone uses race to idle which procesess overything as fast as possible to get the cpu back it low power idle state.

I normally charge my phone before go to sleep, I don't overcharging it during the night.
My SetCpu frequencies are Min 19/ 692 Max.
I am connected through 3G data ALL day and I am always online on Skype, I use my phone a lot, browsing, games, and phone call, and I can tell you, thanks to the undervolting, I got home at night with 50% juice remaining.
Without SetCpu, I would have 10/15% left at night...
yukinok25, that`s huge improvement, I`ll try it definitely.

And...this is why we all love XDA...
Remember that battery life also depends on Radio version and kernel installed.
I remember there was a topic about "How to charge your phone first time" - cannot find it any more.

If you mean after you just bought it, Its enough to let it fully discharge twice, without charging it, in between this two circles.
Anyway with nowdays Li-ion battery, you won't really need to this so anymore, since the lifespan of battery start to decrease from the moment that they left the production factory.

Sorry for my english.
I meant during your usage time (during the day) don't charge your phone at all. let it discharge fully twice.

I would not recommend juicedefender. Doesn't do anything at all. The only thing I notice is that nu wi-fi turned itself off when it shouldn't.
You could try AutomateIt. You can set up your own actions.

is it just me or is the kitkat ROM really sucks----battery pretty well?
I also notice that the CPU usage does not drop to 20 percent idle but when I used other ROM (JB based) it becomes 5 percent.
RAM usage is good but I think it hogs the CPU. I used cpuz on measuring the cpu usage

Where can I get the JB rom for OGP?
For me, Android was best at JB and went backwards with KK.
Yes, I've noticed absolutely horrible battery life with KK. KK just feels like it is several different parts all just thrown together.
The only reason I think is that theoretically JB uses more battery is that the system uses more voltage than the kitkat. however, what's less voltage use if the CPU is always busy and wakeups are just everywhere.
Hi guys, maybe you could post in some battery stats so we could know more about whats draining your battery in particular and suggest some fixes. I've actually experienced the opposite with kitkat-battery life for me improved. There was even an instance that I got the phone to last 30 hours, with 5 hours, 48 mins. screen. On another instance I got 15 hours life and 5 hours 25 mins screen on. I just lost the screenshots as I had to reflash stock when i was doing some G3 mods., but nevertheless i could post some new ones.
I value batter life was well and i'm curious to see how yours could be improved too..

What a battery life. 15 hours screen time?
how can we accurately measure? because I only use CPU-Z and installed DS battery saver to save power. right now it only used 2% of my battery during the night. (from 1:45 - 5:50am)
I see. can you tell me what app should I use to determine CPU usage of each app/service?

No, my battery lasted 15 hours, and my screen-on time (total time i spent using the phone) was 5+ hours coz i basically used my phone then for gaming the whole day I suggest you download gsam battery monitor app (it also has a temperature_bat. Usage graph), as well as wakelock detector. Another alternative would be better battery stats. What you would need to observe would be the apps and wakelocks draining your battery both when you are using your phone, and also when its idle.
I also notice that battery capacity is 2A in which it should be 3.140A right?
this shows on kitKat but on jellybean, it's 3.140A again.
is there something wrong with the detection of battery capacity?

What happened was that in kitkat, the permisssions required to be able to access battery stat files changed. Thus, apps w/c could freely access the batter stats in JB cannot gain complete access in Kitkat. This is the case for some battery monitor apps w/c now have lesser accuracy in reporting battery. No worries though, as there are means to bypass this problem. If you have xposed you could install a module for this. Also, some apps like gsam battery monitor come with a separate root companion app. Once you install those batter stats will be accurate.
Here's a screenshot of my battery stats for today..might not be 5+ hrs of screen on as i did a lot of rebooting today (themed with g3 tweaksbox). Nevertheless, this is just to show that kitkat has the potential to provide good battery life. Also enclosed is a screenshot of one of the battery apps i use, gsam.
Hey everybody! I have some findings I absolutely must share so you can benefit as well.
I've been doing some tinkering and I've find a way to significantly increase battery life on the OGP.
First thing you'll want to do is put your phone into airplane mode.
Second, turn your screen brightness down as low as it will go. I mean, all of the way down.
Third, don't play any games on your phone.
Try those three tweaks and see what kind of battery improvement you get.
Unfortunately, Camera has stopped.

Just so you know, first my cell radio and wifi were both on the whole time. Second, i was on auto brightness the whole time. Third, i played clash of clans as you see in there.
If you have not done this already, adjust your cpu to save your battery juice. Set the cpu governor to powersaver or interactive mode if you just using the phone to send msg and make calls. I let my phone run on msm-dvcs and when I'm not plug in. Check out ROM toolbox if you're rooted. Seriously folks, instead of complaint about how much the roms suck the juice, try these different ways to see they make any difference for you.

I found a way to make my phone last a long time. I just turn my phone off and don't use it. I wish I would have though of this sooner.

hello, you should check for battery temps, using apps like Devinfo, my CPU is fluctuative too but the battery usually under 40 con light gaming, and up to 46c when playing genshin impact
