Hello,
I test the battery drain with these two scenarios:
1. When I charged the battery to 100% , then place it in my room for overnight, and I found the average usage of the battery is 2/% per hour.
2. When I charged the battery to 100% , then take it to my office, I traveld and use whatsapp for a while, then I found the average usage is 4.2% (Sometimes, I think it is also 4.2 % even I don't used whatsapp)
3. I think when the my phone galaxy N7000 with 4.1.2 Jellybean is traveled, the battery will drain more fast, I found the wakelock time of multipdp and secril_fd-interface is almost doubled for Battery Better Stats when I
Traveled the phone.
Question:
1. Is my guessing correct?
2. If it is, how can I reduce the wakelock time if I traveled the phone?
Thanks.
I've always found this to be the case on Android phones - haven't figured out why.

The battery life on my Desire is horrible, and I would like to acheive some of the great battery performance I've been reading of other members. I've got LeeDroid 2.1a A2SD+ ver., with the 38.44 radio (I installed older versions in hopes of acheiving better battery). I am now getting far worse performance then when I had new versions of LD/radio, because "something" is draining the battery. ie. Before, I'd get 15% loss per hour during the day, and 1% loss per hour at night during my sleep, with the screen and wifi ON, (using GentleAlarm night clock, which shows the time but on a dimmed screen). Now, I have a 75% loss during 8 hrs of sleep! I even installed "Juice Defender" (Pro ver. with "Ultimate Juice"), which turns off wifi for a few hours, etc. It did nothing to improve battery life, or possibly made things worse. I tried uninstalling some programs, but nothing's changed yet. How can I find out which program or configuration is causing the battery drainage problem?
Battery Indicator Pro stats (8h40m since unplugged):
DISPLAY: 42%
CELL STANDBY: 26%
WIFI: 25%
ANDROID SYSTEM: 5%
PHONE IDLE: 2%
Quick Info stats:
Running: 95.9%
Screen on: 95.9%
Wifi On: 95.7%
Wifi Running: 95.6%
Wi-Fi drains faster than anything, if you're not using it then shut it off! Also, 15% drain per hour during the day and 1% at night isn't that bad. I would switch back to your first configuration. Maybe you're not taking into account how much you're really using your phone?
Well I'm comparing battery performance when I am NOT using my phone at all (during my sleep), and its night and day. When I was getting 15% per hr, 1% loss at night, that was with wifi ON (ie. JuiceDefender was not installed then, and it cuts off Wifi at scheduled times). I'd like to switch back to my first configuration, except that's my prob lem: I have no idea what that configuration was exactly. Lots of programs installed and uninstalled since. I'm going to take a look at a few apps though that might help me understand how to control battery performance.

Hi folks - this is the first thread I have started, hence requesting the non-noobs to go easy on me... (this forum is a scary-kind-of-cool)
I mustered up the courage to install Infused 1.5.0 on my stock... the instructions were superb and everything went great... really enjoying the improved speed and looks. But my battery life has degraded. It has been more than a week since I flashed my phone - and it is only getting worse. Now I have read a lot about how Infused is getting great battery life for some folks... and i have gone through those threads, trying to figure out what I am doing wrong. This is my typical usage profile
1) I put the phone on charging before I go to sleep... when I wake up (around 7 AM) it is fully charged.
2) I quickly check overnight messages, finish the daily ablutions, and 30 min later when I check the phone it is already at 95%.
3) By 10 AM, I have made a few long phone calls (no bluetooth) (totalling 60-90 minutes) - and the battery is down to 75%
4) At work I use a bluetooth A2DP headset - maybe 30-40 min of calls and by 12 I am at 50%.
5) More calls in the afternoon, intermitted mail checking and sometimes 30-40 minutes of music streaming on my bluetooth headset - and by 6 PM my phone is down to critical level 12-15%.
This is in now way the same experience that others are having with the Infused ROM and with the Infuse phone in general.
Other points:
6) I run Juice Defender... (don't know if it helps)
7) My screen brightness is just a few notches over 0%
8) My data is always on - except when I am using Wifi of course
9) I turn bluetooth off when I am not using it
So that's the story guys... and I would eternally grateful if the awesome folks out here can help me figure out what I am doing wrong... or there is some logic behind the sad battery life of what is otherwise the best phone that I have ever owned.
It depends how long Infused has been running on your system. After about 3 days I noticed my phone was adjusting to the ROM and the battery life improved significantly. Aside from that, try this trick. Drain your battery next to nothing and then charge all the way. Do this a couple of times. Not quite sure about the logistics but it seems to work. Another thing that has improved my battery life is to make sure I don't have background apps running. You can check this by going into apps > manage apps > and then running. Sometimes Media Hub will begin a background process and that eats up a whopping 8 MBs alone. Force close these pointless background apps and you should see an improvement there as well.
have you conditioned the battery and reset battery stats?

Thanks popesmasseuse (you really aren't are you?)... the ROM has been running now for a week... gets worse rather than better. I do typically wait for my battery to drain completely before I charge it... but when I do have to do it at 7 PM - then I can never charge it fully, before I have to start using it again. I wonder if the fact that my phone goes through "micro charges" is a reason for my declining battery life...
Will check the running apps... and see if closing them improves things... thanks!
Fact: Installing a ROM greatly improves battery life... Try it....
Turn of GPS and Bluetooth when not in use.
Same here I uninstalled media hub... period... just useless...
Phone calls are a pretty heavy battery drain. Sounds like you're in call for hours each day. Most people don't talk on the phone more than a few minutes a day. Poor signal will also significantly reduce your battery life... how many bars you usually have at work?
My battery life got better the longer I had the infused ROM. But personally I only talk on the phone maybe a total of an hour each day, but I am constantly using internet and youtube, and if I have spare time I'm using my Kindle app to read some books. I keep my GPS, sync, and wifi on all day long and my brightness all the way up (I just can't stand a dim screen lol) and by the time I got home today my battery was at 40%, which I am perfectly fine with.

Ah...the man himself.
Yes I talk a lot on the phone - nature of the job. 3 hours minimum in a day. Signal at home is terrible - 15% strength... that could be the reason why the battery runs dry after the morning routine. Any way to offset that?
At work signal is great. But in office I also tend to use my desk phone more...

Err... no... Noob alert!!!
How does one do that?
http://forum.xda-developers.com/showpost.php?p=14912331&postcount=7
Read this post in another battery thread I am doing this right now to see how it performs afterwards.
Read the thread in my sig.
Never use task killers.
For me, battery life on phones gets good after about 2 weeks or so.
With light to medium use I can easily go for 2+ days.
Consider not streaming music through Bluetooth. Also don't auto sync stuff every 15 mins. If you can use Gmail they use Push notification. I'm on my phone all day literally and I make it home with some battery left. BTW connect to a Wi-Fi when ever possible, 3g data streaming will kill your battery quick.

has anyone tried this method?
It's a Lithium-Ion battery which means it does NOT respond to "conditioning".
"Reconditioning a battery involves completely discharging the energy from a battery then recharging the
battery. Li-Ion batteries do not require reconditioning to maintain good battery performance since Li-Ion
does not have a memory effect. It is necessary to complete drain and then recharge a Li-Ion battery in
order to determine its current capacity level, but that is not the same thing as reconditioning the battery. Li-
Ion batteries do not have a condition that needs to be reconditioned." lxe.com

Keiht's tutorial is effectively a technique called "bump charging" for putting that last extra percent or two of charge into a battery. However - with Li-Ion batteries, charging like this will SEVERELY reduce their charge cycle lifetime.
The only thing that "calibration" should affect is how your device reports battery charge level, NOT actual power usage. You should get the same total battery life whether your device is "calibrated" or not, with the exception possibly of the device shutting off prematurely because it thinks the battery is lower than it really is.

I would have to agree with you. I followed his directions as i was having horrible battery issues after going to 1.5.0 and it seems to have helped the reporting as far as I can tell. I think the big problem and it is only a guess is how the phone is reporting the battery condition not actual battery left. In any event I am running JD and the longer I run with 1.5.0 the battery seems to be lasting a lot longer but I have ti disable most everything which hobbles the phones best features to get that battery life still searching for the perfect solution.
Hi guys
I should be picking up my SGS2 today and I was just wondering what exactly I should be doing with the battery? I've read in a bunch of places that draining the battery fully and then recharging it fully gives better battery life, but I've also read this:
Lithium ion batteries do not respond well to full discharge, you will see reduced capacity and early failure if it happens too often. In any case it is not possible to overcharge the battery on a BlackBerry because the battery and phone have enough intelligence to control the charge (unless the battery is already defective).

(this is from crackberry.com but you get the idea)
What's the best thing to do?
And on Android phones, when the battery indicator shows 20% or something, is that when the phone is going to die? Or will it die at 0%? Obviously at 20% it would be to protect the battery but maybe Android has been programmed to show 0% when the battery is actually at 20%.
Thanks,
Elliott
read manuals !!!!!! You can see this
Did not receive an owners manual with my phone. Anyway...phone is charging now so too late I guess...

The manual is probably stored on the phone, at least my new Ascend II came with its stored on the phone, you have to goto the big menu (forgive me for not knowing the technical term for it) to find it however
i got my battery fully charged...then in the first day i discharged it till 10% at least that's what my phone was saying
i read too that the new li-ion batteryes do not need to be "formated" (fully discharged till the phone dies and then fully charged with the phone turned off) in android case i think that thing is not posible coz it needs at least 5% to pass the bootloader and then begin to charge
anyway in my manual it says that the battery will begin the normal state after 8 days of use, until then it may disschage quick
i have a motorola defy
Calibrate the battery. Charge the phone while its switched off for about 6 hours, and then use the phone untill the entire battery runs out and it switches off on its own. After this, the phone should be able to use the battery properly.
i just used my galaxy and made it empty, then charged it full.
nowadays i have runtimes from 3days (72 hours) and then its @ about 5%
there seems to be a lot of back-and-forth regarding whether or not draining a battery is healthy; i drain my iphone battery down to zero about once a month and the battery has been doing fine for two years . . . whether it would be doing just as well without the draining time is anyone's guess.
I have always been under the impression that lit-ion batteries do not need any kind of special care or break in. But since our phones estimate the charge, we should occasionally let the battery run out to reset the calibration in case it gets screwed up.

I don't think you need to worry about draining the battery till it's dead. My phone dies often and the battery is still kickin It's my understanding, that the purpose of draining the phone before you charge it is to calibrate what the OS says for charge remaining to the battery's actual charge.
Or something like that...
Hi all,
I have my sgs 2 since June and it's working pretty well apart from the battery drain which is very harmful in my daily life
I've recently flashed the Cognition 1.30 (last friday). Before that, my sgs was able to last the entire day before discharging with a moderate use (10-20 mn on games, few sms, 15 mn consulting mails, 1 hr on internet). Since i've flashed with the cognition Rom, the battery drain is really awesome!!!!!!
I fully charge the phone (switched off) then when i switch it on and the phone stays idle, after 1 hr or so, i've already lost almost 20%. When i'm on internet or playing games, the battery loss is approximatively of 1% per min.
I've made a full wipe and recalibrated my battery so normally it should at least last a day and thats not the case.
Could somebody help me or should i buy a new battery and test it ?
Because i relly like this rom and from others users, it has a good feedback concerning the battery use
I have had quite bad battery drain issues for a while, and searched BBS dump files and forums for an answer, but the logs appear normal with no unusual wakelocks. In short, the battery consumption profile is OK but it just goes too fast. So I concluded I needed a new battery and was too cheap to buy Samsung original battery and instead got a noname type (same capacity, 1500 mAh).
But it didn't help. Still 12-16 hr standby with low use (<1 hr screen time at lowest brightness).
So I tested the health of the two batteries by draining them as fast as possible. I used the app "Battery Drain" (https://play.google.com/store/apps/details?id=com.fuzzyoneapps.BatteryDrain) and drained using full screen brigtness, wifi, bluetooth, gps, CPU but NOT the vibrate function.
The results are attached to this post. As observed, there's no big difference between the two batteries. And I don't know what to expect.
So now I'd like someone else to do the same test so that we can compare the results
Basically, just 1) Run the app with all the settings turned on except vibrate, 2) make note of battery percentage, 3) leave it for exactly one hour, and 4) check percentage again. Is ~45% per hour normal for the nexus s?
Thanks in advance
Hello,
I installed yesterday chroma with hellsgod kernel as described here on my Nexus 4
http://forum.xda-developers.com/nexus-4/development/rom-chroma-03-31-2015-layers-t3069936
Everything worked fine and I was able to use my phone without problems.
The only downside is that the battery life is horrible. Before I was running the stock 5.1.1 and the battery was lasting more than 1 day with my "standard" use, or at least 4-5 hours with display always on and gps.
Now I noticed that using gps the battery life drops to ~2 hours and the phone doesn't even survive a night in standby.
Looking at the battery use, I can guess there is something terrible going on
http://postimg.org/image/esjjgc4gd/
the battery level completely disappeared when I put it standby when I went to sleep. When I woke up (alarm didn't ring of course) it was at 5%. I charged the phone and reboot it and you can see it shows from ~15% to 55+% in the time of the reboot (the small empty space).
My questions are:
1- is it a known problem/bug of the kernel or maybe just battery monitor issue?
2- is there any way to fix it?
P.S.
I have not changed house/use of the phone nor any relevant changes in the environment/electromagnetic fields afaik
