[Q] [HELP] Draining battery - General Questions and Answers

Hello,
I need some help with my evo...i have it running on the fresh 3.5 ROM and netarchy-toasts kernel, latest version and all. I am overclocking as well, but nothing to drastic. Until recently, the battery life on my phone went into the ***** literally. Before it went 24 hours plus with medium to heavy usage. Now i can leave the screen on and literally (no exaggeration) watch the battery drain sliver by sliver. I just did a complete data wipe and reflashed the rom and kernel both in hopes of resolving the issue, but its still draining. Any help would be greatly appreciated, I really need this fixed but cant figure it out on my own :/
edit: the only time this happens is when the screen is on, when the screen is off it STILL DOES drain more than usual, but nothing compared to what happens when its unlocked. My though is that an app is running in the background eating up my batter life, but i have no clue what it is or how to locate it.

This is what the battery usage is looking like. Always Android system up at the top

Disable your mobile connection when not using it turn auto brightness off off auto sync but the main factor is.the mobile connection turn that off when not using and u we get better battery results
What's gd for these kind of things is juice defender

I forgot to mention that i have juicedefender installed already, and set cpu with profiles as well. one of the profiles is for when the screen is off, set for 300/300 (not accurate, but is set around that)

If its going as fast as you say (literally draining in an hour or so) I would say check your batter, try a new one. Otherwise you already have juice defender (which I tried and it really didn't do much else) so everything should be covered. Try wiping Dalvik cache, also try wiping batter stats (both are in clockwork recovery under the "advanced" tab.
Good luck and sorry if this doesn't help

Hey,
Download Juice Defender and AutoKiller fro the market and watch the Magic. me and you have the same phone and same rom. Note: delete any tsk Managers ou have because they will interfere with juice defender..

"screen on" causes drain
There is no a magic solution for that, you just could calibrate the battery as usual, try to set the brightness to the lower level instead of automatic, use only 3G connections when you gonna browse or download something, if you just gonna check the email or whatsapp, etc. you just could use 2G Edge connections to improve the battery life, does not use live wallpapers and root your phone, use an app like no-frills to set a custom processor speed, etc.
but... more than 24 hours with battery it's like a miracle.
I would also try to figure out what causes your phone not to go into deep sleep. Many times your screen is off butbthe phone is awake. BetterBatteryStats might help you with that.

there must be some apps running in the background and prevent deep sleep of the phone and this causes the phone to stay at 300+ mhz looking at the "awake" time of your battery history.
i can just give you the advice to close an app if you dont use it anymore, always close it via the BACK button not via HOME because multitasking might be very cool but the app wont close automaticaly.
Use a task manager ( im actually using the standard task manager) and close the apps which are currently running. You can also check whether your phone goes into "sleep mode" or not with the app CPU Spy. its free on market and shows you the history of your processor speed.
Disable wifi 3g and stuff if you dont use it and close all apps and wait a bit. Then check via CPU Spy if phone was in "deep sleep".
Also how many RAM usage do you have by average?
I get 16-18 hrs of standard battery life.. Is it good? Also my average RAM usage is 330-380...

And just by typing this I lost 2 percent
Flash Matr1x to start. See if that helps. Also, look at what apps are running. settings>apps>running. See if anything there is on a lot, and stop it. Turn auto sync off.
I get about 20 hours of decent usage with this setup
every kernel and rom combo is going to perform differently. I find the best way to get the most out of my battery is to calibrate the battery by fully charging, allowing the battery to fully discharge, and then repeating those two steps once or twice more.
You without me is like Harold Melvin without the Blue Notes...
download battery calibration app from market, fully charge battery (94 or 95%), then calibrate using the app. Allow your battery to fully discharge (until it shuts itself off), and finally charge your phone completely with it still off. You should notice an amazing enhancement in battery life.

what I do is: (Use NSTools, its easier to make this setups!)
- Use LiveOC on 110%
- Overclock to 1110 Mhz - 200 Mhz
- Activate Deep Idle
- Use Lionheart governor.
Try this and see if it helps.
Turn off GPS and nfc if you're not using it! And wifi if you're not connected to a network, I think that may help something!

How about you tell us your on screen time?
Seems like your phone is on for quite sometime given that is it at 41%. Usually during a normal day mine usually consumes 28% with 2 hours of on screen time.
If you're hitting 4-6 hours of on screen time, that battery stat is NORMAL.
Thank you guys for your suggestion but i think my battery is just too old
im ordering some spare batteries for amazon
Tell me what you think about these

Battery Eater: Google Services?

I kept my (at 100% when I went to sleep) phone unplugged last night while I slept to see how it does when it's idle. (when I'm working I'm running WiFi tether which obviously sucks battery life so I've not seen how it sits.
6 hours later I woke up to A battery at 71%, which was kind of surprising. I've attached some screen shots.
I run CleanROM 6 with its stock kernel. Would a different kernel help?

Are you on Wi-Fi at home? I've read some people having this issue and they've turned off the Wi-Fi power management feature and it seems to resolve this. Settings--wi-fi--menu key-- advanced should get you to the right menu (I'm on an aosp rom so not sure if it's in the same exact place).
Also an app like Better Battery Stats might provide more specific information about whatever is draining you.

Same place I described. It's the box "Wi-Fi optimization."
Thanks Dearborn! I just changed the setting so hopefully it works! I didn't even know that existed!

I have the same prob since CR6v2 (50% Google Service batt use when relatively idle) and have always had my wifi set to stay on when sleeping (assuming that's the setting you're talking about). It seems clear via GSAM and normal batt stats that Google Services is causing wakelock. GSAM says, "included packages Google Contacts Sync" but I'm not sure if that's conclusive or if it's just providing an example.

Higher battery use on 4.4.1 - here are my battery stats!

Ok. On 4.4 (with linaro version of franco kernel) i could leave wifi on and overnight get 2% battery loss.
Now on 4.4.1 (again with linaro version of franco kernel) i get 5% overnight loss. Nothing else has changed!???
Here are my battery stats...
(i plugged it in just before bed so it'd reset the 'unplugged')

I think betterbatterystats is what causes the battery drain in 4.4.1, i uninstalled it and no problems.
Based on the screenshots (log from BBS would be better as some stats are missing in your post) you've got WiFi on with few applications utilizing it. Like SwiftKey, Facebook and few others. Review your WiFi configuration (you may also need to remove/forget your WiFi network from the phone and configure it again - that seem to fix certain WiFi issues at 4.4.1) and check again.Also try with WiFi off for comparison.
Thanks I've just forgot the wifi and rebooted then re connected, I don't get why SwiftKey is using it? It's a keyboard!?

5% loss overnight is still decent I would take that
mine seems ok
edit. seems the pic has gone wrong. it shows the battery going up a few per cent overnight
I know but it's over the double the 2% i used to get!
Sent from my Nexus 5 using Tapatalk
I also feel the battery drain quite a lot faster. About two times faster when idle, and i see quite a lot "awake" caused by the Android System when the screen is off.
@wheilitjohnny
that must be coming from some process. I don't have such issue, it's pretty much the same as it was on 4.4.
I've not changed any apps etc since tho. That's what's annoying

[Q] What is com.android.systemui and why is it gobbling so much battery?

Since flashing Carbon ROM two nights ago, I've been seeing com.android.systemui consistently at or near the top of my battery stats screen (screen shot below). When I was on Cataclysm, I never noticed this. Is this something I should worry about/deal with?

You've only used 3,% of your battery. See what it looks like later in the day. It should be less than 5%. If it isn't then yes, something is not right. Turn location off until you need it. That week save battery.
Sent from my Nexus 5
the % used in the graph is the % used of total battery drain.
you only lost 3% total battery and 49% of that 3% was used by the system.
there is no problem as of now.
Check out lockscreen notifications if you have pocket mode on it keeps the proximity sensor on all the time and will cause a larger than normal drain.

This is very helpful. Thanks -- I'll try disabling lockscreen notifications/pocket mode.
You cannot tell anything from stats after only a few percent of battery drain. Look again after you've burned 90 percent off the battery.
