Hello Guys,
I have searched this forum for the answer, but did not get anything definite. To start with let me give me my battery statistics. This is the average result of my everyday use.
Android OS 46%
Display 23%
Maps 10%
Android System 8%
Cell StandBy 5%
Wifi sharing 4%
Phone Idle 4%
I want to know why Android OS is eating most of the juice. I have seen answers like disable Wifi, GPS etc. but I find it very surprising compared to my Nexus S. For the sake of experiment I gave the Nexus S and the Galaxy S2 a full charge from below 15% and used it identically (the settings, service provider, applications all were exactly same maintained). I watched movie for 30 minutes, and then kept them aside for 2 hours. Then I picked both of them and found Galaxy S2 to be significantly more discharged. The difference I found was due the consumption by Android OS in Galaxy S2.
I tend to think that this is a set specific problem. Can anybody help. Thanks in advance for the help.
Can some body please help on this....

P.S.

Hello dear community,
Giving the plethora of sports accessories that have been lunched lately and their ability to track motion and other parameters, it seems pretty easy to track someone's sleep. And because my wife has sleeping problems, I've been thinking of digging into the subject a little bit.
I've read here and there that human sleep has 90 minutes cycles and, for one to wake up fresh, he/she should sleep a multiple of 90 minutes.
So I'm asking you: has anybody tried a phone + accessory combo and managed to improve his/her sleeping habits? Please give more details!
I wish you a good night sleep!

Hi.
I have Samsung Galaxy S3 collecting dust... so got idea to make dedicated GPS out of it so that I don't have to use my nexus 5 all the time in car. Any suggestions about this? Currently have cyanogenmod 11.0 on sg3 with tasker and sim card for mobile data only. As for navigation apps: waze, here maps and maps with me. My biggest concern is battery life because phone will be in car 90% of the time without usage... and even if i'm using it and charging I don't think that using waze+gps+data+display brightness would last battery for half a day (battery drain > charging???).
Use tasker to kill all useless processes to preserve battery?
Set processor state lower?
was reading something about "deep sleep" whatever that is when no using?
different rom?
Any ideas? Maybe someone has done something like that?
Thanks in advance for suggestons.
try cm10.2 is more economical and underclock to grows up life battery, i point kernel Boeffla :fingers-crossed:
Hit thanks button if helped
So I've had my S6 for just over a week and am really enjoying it, unfortunately though I am experiencing some serious battery issues. Most nights for instance I'm losing about 30% while I sleep and that's with mobile data and bluetooth turned off, the only thing on is WiFi. Here is an example from last night, I went to sleep with it on 90%, having used a few apps before bed and then woke up with it on 60%:
Any advice?
Turn off...
NFC
Location History
Facebook Sync
Set Wi-Fi to only scan when it is on

You have 3,5 hours of wakelock/held awake. This way more than Facebook/Google service. I suggest confirm that deep sleep is working and that you look into the wakelocks. This isn't just facebook and Google location service.

Can you advise how I'd do this? Haven't been on Android long and didn't have these issues with Z3

CPU Spy can tell you if your phone gets to deep sleep.
Better Battery Stats can show you wakelock.s. BBS also shows you deep sleep, screen on and such, which can be helpful when troubleshooting wakelocks.

Really! I mean REALLY....battery life again.....come on. its so subjective. While most posters moan about battery life on smart watches and mobiles etc I turn this point on its head and rather marvel at what such devices deliver considering they are powered by such small batteries.
The vast majority of mobile owners moan about battery and cannot accept the batteries limitations.
The watch is not even on sale yet but we can guarantee it will please a few and upset the majority .
If you want year long battery life one has to look at the conventional watch not the smart watches. Even better go automatic.
Too much amphetamines bro. Lol.
2 full days on Gear S now
I get 2 full days on my Gear S now, so am hoping the S3 does the same with Always On feature active. I do not mind charging daily though, not a big deal.
I get 2 - 3 days from my Gear S2 easily.

Hey guys...
I have yet to tweak anything on the watch and it is connected to my S7 Edge.
I get less than "a Business day" use out of the current out of the box set up. This is the NON-LTE version.
Things worth noting:
1. I do not use always on.
2. I have brightness set to 5 during the day and 2 at night.
3. GPS, Bluetooth, and location are on.
4. Have not altered the out of the box systems that monitor health yet.
5. I have added several apps, Flipboard, Gmail, Gcalendar, Uber, white light, google map, xenozu(you tube-player), calculator, remote camera, weather monitors 2 cities and several watch faces.
6. having it 100% charged at midnight/1am and no use other than sleeping with it on leaves the watch at 50% by 7am.
Anyone finding or knowing what tweaks and adjustments start saving on battery life...please let me know. I will report once I make a few changes as well.
I am sure with some simple changes, we will all be able to use the watch all day without charging it. Anyone that found any changes to their older S2 helped?

I have had the non LTE version Gear S3 since launch day. I can go through a full day (7 am to 11 pm) and the battery level is b/w 50-55%. I have been wearing the watch overnight to monitor my sleep the last several days. When I wake up around 7 am, the battery level is b/w 45-50%.
Settings:
Display: Always On activated
Bluetooth: On
Wifi: Automatic
NFC: On

It is not Gmail or Gcalander...it is a Samsung or 3rd party app that syncs with my Google stuff. Again my apologies.

I can get 1.5 to 2 days of battery life. This includes roaming around for 2-3 hours a day without my phone. I had to condition the battery a few times (draining it to 0) before it would last more than a day.

i dont know what they did in the last update , but ive gone from almost 3 days to not even 1 day now on my frontier ... im not impressed at all, i missed my alarm this morning because of a flat fkn watch ....
I need to recondition the battery, but after turning off "diagnostic and usage reporting" I found that the battery life has increased from 1d12hr to 2d16hr. I feel like that had a huge impact.
Canadian S3 Frontier (SM-R760) on XAR. Have yet to use Samsung Pay, but it's on there now. See post #290 this thread for details on how to change Frontier CSC.

On Gear S3
Settings>About>Scroll down
it's second from last
My personal experience with the problem of strong battery drain on Gear S3 classical vers after updated with tizen 3.0:
- I have read that this was a common problem and several posts regarding this issue
- I have factory reset the watch
- I have changed my band from curved to standard. I had one of the nice curved version, I have changed with a standard band that allow the hearth rate monitor to be completely on my wrist. Please note that I have a relatively small wrist for others this may have no significance.
I did this because in one post I read that Samsung has changed the AOD setting to be managed not anymore by Gyroscope but by the heart rate sensor
- I have designed with Gear watch Designer several faces. I have observed that the main issue was that the AOD was not reducing the brightness.
Then I have designed a face having very lo brightness in the AOD version (6.6% ratio)
Now comes the strange......
- I have tested the watch for few days with the same settings (no wifi, no location, brightness level 5, AOD on, BT on) and doing the same things starting from full (nominal) charge 100% in the early morning .......
RESULT
- The first hour or so the battery level decreases very quickly until 90% (approx rate 10% in 1 hr) but then (...... surprise surprise .....). the discharge decreases and stabilizes for the rest of the day at a rate approximately of 4% per hr.
After 12 hrs of use I have about 45% of battery remaining
I believe that the watch does not charges completely in real and that the 100% is only nominal
ever since the last update, i have been getting a solid 6-7 hours of use out of the battery
