Battery life issues

I'm running the Mahdi rom 2.5 on my gpad and my battery life is terrible. I have been doing some basic Web surfing for the past hour and the battery dropped 20% . I checked battery stats and it says the screen used 90% of the battery. I have it set at 70 percent brightness which doesn't seem to high. I'm new to Android so maybe I'm missing a setting . Any help will be great

One thing that helped my battery life was turning off the location access in settings. Alot of apps these days like to monitor your location to assist in features they have within their apps.

That seems about normal.
With the screen all the time on you can get about 5 hours of battery life.
It's the screen that eats pretty much all of the battery so there's no solution for it.

I was thinking 5-6 hours sounds about right too.

I'm using Mahdi rom too, but it's not that bad, I think it's generally the G Pad not brilliant on battery.
I know this doesn't help with on-screen time, but get yourself Greenify app which helps with off screen battery usage. You'll need Xposed module for it to work.
You can stop wakelocks for certain things too. Get yourself Better Battery Stats to show you what's eating your battery up, especially when in sleep. When you know what's causing wakelocks, you can block them with the Rom.
You can turn this feature on under Settings > Developer Options > all the way to bottom, find "Wakelock Blocker" > Click "Enable"
Here's a few which cause problems, for me anyway, by all means try them out and see if it makes a difference:
- ActivityManager-Launch
- AlarmManager
- AudioIn
- AudioMix
- GCM_CONN_ALARM
- NlpWakeLock
Hope that helps.

All those things don't really help, unless you are losing more battery than a couple of percent overnight (which shouldn't be the case normally)
Actually I think that apart from the screen the G pad is very efficient and hardly uses battery when sleeping.
And there's nothing you can do about the screen being power hungry.

Thanks for the help guys. I guess I will have to keep it close to the charger.

G Pro Kitkat Battery hogs

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.

That's pretty much a tablet use. You want great battery buy a zero lemon battery, the bulk is worth it, I got 3 days with very heavy use

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.

[Q] CyanogenMod 11 is killing my battery. Help!

I've looked all around for any thread similar to this - couldn't find it.
Long story short. I rooted my phone and installed CM11 (Sept 14). My battery used to last around 30 hours. Now I'm lucky to get 8 or 9. Without any use, I lose around 40% during the night (7 or 8 hours). I used to lose 7 or 8%.
Is anyone having the same issue?

Go to the battery tab in settings and find out what is using the most energy. You can also use greenify to monitor usage.

Or try diff kernel..

what are your governor settings, and clock settings?
You can use Better Battery Stats to track down what is causing the drain.

Clock is stock, governor settings are at "interactive". I got Better Batery Stats. "Android OS" is draining my system. There were a couple of modules mentioned. I was expecting a rogue app was eating up all processor cycles.
I downloaded the Deep Sleep widget. My phone had a 35% deep sleep time.
I'm pretty sure it's doing something all the time that is draining the battery...
So I installed DS Battery Saver Pro. All I can say is WOW. Battery drain went from 7% (on stock Galaxy Note 3) to 40% on CM11 to...
0% overnight / 97% Deep Sleep
That's right. 0%!!! I can't believe it! Battery life is so much better and performance is basically the same.
I guess something was keeping the phone awake with CM11, and DS Battery Saver Pro fixed it!

Okay, it seems like the app Greenify helps a bit but doesn't completely solve the problem. Try that and let me know what you think.

Not that this will help you, but I had the same issue. Normal usage would drain before the day was over...went to Tweaked 3.55 and problem went away, which sucks because I LOVE CM11 minus the camera...for some reason I think the camera is always better with stock based roms.

DS Battery Saver Pro only did so much. With normal usage my phone simply won't last a whole day. CM11 is killing it. I have nothing else installed...

Found it!
So, I found what was eating up the battery. The battery stats didn't help. DS only saved some of the battery at night. The phone was simply consuming obscene amounts of energy while on and every indicator seemed normal.
It was ART!
I went back to stock Touchwiz and hated my phone so much I was this close to selling it and getting a OnePlus. But I reinstalled CM11 and decided to add apps one by one to find out what was going on. Everything was fine and yesterday I finally enabled ART in the end. The phone wasn't any faster, but it went from spending 3-4% battery at night to 45%. And during the day, it dropped 1% every 2 of 3 minutes with light use.
So, there it is. Blame ART and never enable it on CM11 if you have battery issues.

Occasional Poor Battery Life (Stats reveal nothing)

Some days by the evening, my battery is still at 70% other days it's flat. My usage patterns are very consistent. On a bad day, I captured this from the logs, and it looks unusual to me. Only 1hr of screen time, and nothing obvious from the other stats.
Anyone else seen this? (Rooted N5X with otherwise stock 6.01)

Look at all the time your phone is awake but your screen is off. I would say your wakelocks are causing your battery drain and that your battery stats reveal quite a lot. Try using Better Battery Stats to find out what your wakelocks are.

I have purchased better battery stats, but I can't see anything that looks like a culpret. Can someone who is experienced take a look?
Thanks.

There is a better battery stats app thread on xda
It looks like Google hogging it again, your phone is having trouble sleeping
Since 6 h 41 m 48 s Awake
(Screen Off) (): 1 h 8 m 49 s 17.1%
Level lost [%]: Bat.: -56%(100% to 44%) [8.4%/h]
com.google.android.gms (): Wakeups: 693 (1.7 / min)
*net_scheduler* (Google Services): 1 m 3 s Count:9224 0.3%
WearableSyncService (com.google.android.apps.fitness.Fit): 58 s Count:353 0.2%
NlpWakeLock (Google Services): 53 s Count:7094 0.2%
Etc etc
my phone does not doze properly, compared to my nexus 5, I think Google services are to blame.
I had to remove alot of Google apps from system and install from app store and stop syncs to have proper idle drain, and its better now.
Eg on my phone today, YouTube *net_scheduler* over 300 counts and 24mins awake, It started itself, nor am I subscribed to any users, it shouldn't of been running in the background and I'm having trouble deleting the app

Did a backup and a factory reset of my phone, and battery life is back to normal. At the same time I did upload SuperSU to 2.66 (I was on 2.61), and I noticed in the changelog some mention of fixes that fixed devices not sleeping.
It might be worth a shot to see if it helps others. Please report back if it does. I only noticed it after I had reset my phone (for the 3rd time, to fix battery life problems).

8.1 Battery Drainig - Recommended EX Kernel Settings?

I'm new to my Pixel 2 XL and have the 8.1 update and am seeing horrible battery life. Noticed others in here also experiencing this and wondered if any of you have some recommended settings for EX Kernel that can improve battery life? I only use the phone for notes, camera, calls, messages, etc... Daily use type of stuff. I don't play any games on my phone other than Hearthstone and it doesn't require much to be smooth and I watch some YouTube here and there but it also doesn't require much so anything I can do to get those 6 hour SoTs everyone raves about with this phone.
Standby is great, in use is just embarrassing.

Mine is opposite. It easy to get 6 or more hours SOT using the phone but the thing drops like 10% battery overnight even with battery and data saver on.

Well that's not good. I would much rather deal with on drain than stand-by.

A kernel will not stop a badly behaving app from drawing too much power, or not dozing when it is supposed to. You would be better served in using a battery drain app to find your wakelock/bad actors and deal with them. Beyond the information you can get from the improved Google battery applet, GSam and BBS are two apps that can help pinpoint the application or service causing excessive battery drain. It is not the kernel, and as flar2 states, the new chips are so efficient with power there is almost no room for improvement battery-wise. Most people leave it on the default settings, and use it for extra features and customization.
https://elementalx.org/the-truth-about-kernels-and-battery-life/

I agree 100%, I just thought some settings adjustments with the kernel could do some good and maybe someone might have some ideas on what would help the in-use battery consumption. I'm currently clean flashed with only Google APPs and Nova Launcher installed along with EX Kernel and Magisk no modules. Battery drain only shows android system... Not a lot to tell me what it really is. Will try the apps you suggest
