[Q] Android OS use battery most in Galaxy S2 - General Questions and Answers

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....

[Q] Samsung Galaxy Tab Battery Temperature Problem

Hello, Everyone,
I carried my galaxy tab to some humid places and after that when I tried to charge the battery, the charging paused and came with a message that the battery temperature is either too high or too low.
I am not tech savvy and travelling with the galaxy means a lot to me now that without it I am like travelling without hands. So please forward any suggestion of yours to save my life.

the only thing I can think is that your device don´t close the proccess of some aplications and they consume resources... u checked it in settings-apks?
your device also stops the chargue by low temp¿¿? soo weird,,,
yeah mine too. i got the message pop up. last nite i charged this tab, until morning and get 100% full. after tht, i calibrate it, and take online with it. i check the battery 71%. from 100% reboot, and the battery drain into 71%.
then i play video, but suddenly its now 1%
what does it mean ???
u guys maybe need to have a look in the GALAXY TAB section . there were many threads about this issue .. DO NOT POST THE QUESTION .. use the Search function to get your asnwer fast
just wanna try to help, use the battery calibration. its available free in market

[Q] Verizon S3 w/ CM 10 Battery Issues

Hello,
I got my (Verizon) Samsung Galaxy S3 two days ago, and rooted and flashed it with the CM 10 Nightly builds after a couple of hours of using touchwiz. Everyone has been saying that they are getting more out of their battery with CM 10, but my experience hasn't been too good. I am getting maybe 9 hours of battery with normal use. When I got the phone I run it down to 10%, turned it off and then charged it back to 100%.
I have turned off 4gb (as I don;t have no real 4g signal around me), have the display on the lowest setting and have even under clocked it to 1.2ghz and it's still draining fast.
I have been reading through some forum threads and there are people with the same issue as me, some say they think it’s a faulty battery so they ordered a new battery but never post back there results.
Others say that doing a reset of the phone/reflashing CM 10 does the trick.
I have also experience my phone getting warm to the touch when just checking facebook or web browsing. My phone core seems to be running at 90-95 Fahrenheit when it feels warm and have never seen it go above 100.
I’m open to resetting my phone, but as I have just set up everything, I would rather not to.
I know this is a lot of information, but any advice at all would be greatly appreciated.
Thanks in advance.

a few things.
if youre running a launcher some allow you to backup your homescreen settings, even the free versions
i have never gotten that bad of battery life out of a CM10 rom. Your screen on time is a more reliable idicator of your battery health than hours of use. the hours of use statistic is easy to manipulate
run better battery stats to find any wakelocks you may have to see whats eating your battery.
Re
Thanks for the quick reply!
I'm not sure it's an app that's causing this, as I didn't install anything on the phone once I rooted it for a couple of hours and it was still draining fast.
I have gotten the betterbatterystats app and will post what I find out.
I am also not getting the best battery life. I am on paranoidroid 2.52. I had the phone fully charged, screen on watching a video in skyfire. I did not make 3 hours. Is this what others are getting?
Battery issue
You probably all know this already but the screen brightness level also effects the battery a lot. I set mine to auto.
I'm wondering if you flashed your radio and rpm to the latest leaked jb

[Completed] Strange android system battery draining

Hello everyone!
I own a LG G3 D855 and from the moment I bought it, I've noticed problems regarding battery life. After some resets, the store changed my battery. Despite this, it remained more or less the same. I usually never pass 3 hours of screen-on-time (no gaming!) with a full charge. After that, I considered it was due to the 2K display and reports around the internet talk about 4 hours with this phone, so I became thinking it was quite normal to have this battery life (asking your opinion, guys). Notice I usually have wifi on; 3g, nfc and gps turned off.
However there's a second problem. Sometimes, at random days, like it happen today, I get android system using more battery than the screen (around 50-60%).
I'm avoiding sending it over to the warranty, because I'll be 30 days without the phone and not sure they're figure out the problem.
Any help?
PS: I'm running stock Lollipop, haven't rooted yet. Same behaviour when I had 4.4

Battery life ... oh there are many different fators that influence the battery life.
For example: The battery (capacity and health), the firmware (many the kernel), the apps, the usage, the system/apps settings, the temperature, the (wifi and/or mobile) signal strength, etc.
So it's hard to say if your battery life is "normal" or not.
For detailed discussion about the battery life on your device, please post in the G3 General > Battery Life Discussion thread.
If you think your battery is fine and suspect an app draining your battery, I recommend to install and use Better Battery Stats (BBS) app.
For some stats you will need to root your phone though. But you can record all stats and post a dumpfile from the app to the app thread, and the "experts" will analyze it for you ... helping to identify the culprit.
Thread closed. Thank you!

[Q] Bizarre Battery Drain

Dear XDA Members,
I'm having some issues with the battery of my Samsung Galaxy S4 Mini. About 2 weeks ago, 2 phones in this house, a Samsung Galaxy S4 Mini and Huawei Ascend P7, started (quite simultaneously) to have battery issues. They both are on the stock rom and are not rooted. To sketch the degree of the issue: the Huawei had about 40% after 7 hours standby with 3 minutes screen on time. The Samsung lost 65% in one night just being idle.
At first we thought it were the phones that were having the issues, so we returned the Huawei to the shop (about 40 kilometers away). The people of the shop called yesterday, saying that the phone is lying in the shop for over 3 days now, still having 40% percent of battery. This made us think it was something with the antennas here in the neighbourhood.
In the mean time we had already bought a new battery for the Samsung (an original Samsung battery), and I have performed a factory reset. The battery still drains quite heavily when airplane mode isn't enabled. However, last night the Samsung still lost over 15% with airplane mode enable and all recent apps killed.
I completely lost track about what the issue can be. To me it seems that the fact that the phones started having issues at the same time is caused by an external factor. But in that case, I cannot explain the 15% overnight battery drain on the S4 Mini on airplane mode with a new battery. Should I return the Galaxy S4 Mini to Samsung to have it looked at and fixed, or should I try some other things first?
If anyone wants some more information about the issue or the devices, I'll happily provide it.
Thanks in advance!
Note: It is not my intention to root the S4 Mini or push settings to the limit to have 0% battery drain, I just want 1 or 2 days of battery life again, depending on the usage.
Edit: There are also a OnePlus One and Galaxy Gio being used in our house, who do not seem to have severe issues. This confuses me even more about the external factors (antenna failure?) that might be draining the battery. We all have the same provider...
There are many ways to save your battery life:_
some of them are as follows:---
***Go to recovery and clear cache this will help improve the battery.. Use clean master from play store, which will disable / stop unwanted apps, clear app cache.
***Try using Greenify
***I recommend GSAM battery monitor app from play store. It's very easy to understand and is very good at locating battery issues.

In settings>battery check your mobile network signal of last night and see if there is any app that is sucking your battery.
You should try greenify but you need root access.
Thanks for your answers. If the problems do not get solved I will indeed try some of those apps (I've used Greenify earlier, I know it's great )
I've monitored the apps draining the battery, and in fact there aren't many apps that use a lot of battery. It's mostly the screen or mobile radio active, which makes me think it's something antenna related.
I've spoken to my neighbour who is a customer of the same provider, and he indicated he has issues to since a few weeks. I mailed to my provider and see how things turn out
Thanks for your tips!

Yeah i also think the problem is in network quality, you should try another sim for some time and see the difference.

Really bad battery life

Hello all,
I just bought a new galaxy s7 silver (exynos variant) around 3 days ago and my battery life seems to be really bad. I've only managed to achieve 1h 56m screen on time and I'm already at 41%! I keep auto brightness on and leave always on display off and don't keep things like mobile data active. If anyone can suggest how to fix this it would be phenomenal .
I was quite sad considering I have heard of people who can achieve 5+ hours screen on time with regular usage and not having to compromise on switching everything off .
Thanks for the help in advance
Do you have Google Chrome installed? And can you see something like "media server" in you battery usage log as a high power consumer?

I would send you a picture of my battery statistics but for some reason every time I try to upload a picture I get "network error"
My top consumers are :
Screen 31%
Android system 19%
Android OS 9%
Cell standby 7%
Mediaserver 4%
And Also I do have Google Chrome installed
Good day.
Try this and see if it works:
-In settings -> privacy and safety -> location -> improve accuracy - Turn off wifi scanning (The phone turns on and off wifi regularly for location purposes and it uses some battery)
-In settings -> Display - Turn off smart stay
-In settings -> Advanced features - Turn off pop-up view gesture, Smart capture, palm swype to capture, smart alert and easy mute.
-In settings -> Accounts - Turn off auto sync
Turn off hardware step counter at S-health app.
Use Greenify to hibernate samsung and google play app and services.
And if you want to stretch it more have a look at this (http://forum.xda-developers.com/galaxy-s7/how-to/touchwiz-bloatware-save-to-remove-list-t3330241)
Hope it works for you.

Hi mate,
The 2nd guy in this post touched on it. When you see Mediaserver on your battery stats it's normally a sign that your phone, since being on, has got quite hot and there has been substantial battery drain. I've had this same issue before too. Factory resetting etc wouldn't help. And the phone would get so hot. Eventually I read and found a link between Google chrome and Mediaserver. I deleted chrome and mysteriously the issue left, that was on my last s7. My current s7 I got yesterday and haven't got this issue once, despite using chrome right now.

Yeah I did notice that the phone was heating up rapidly and my battery life was falling heavily. I will delete it and give an update to see if it works.
Thank you
Right I tried it and at first I thought that it worked but then today I am down to 25% with only 2h 5mns screen on time. Anyone got any other ideas?
Sorry read that wrong lol I read 25% battery for 2 hrs screen on time!
Accounts syncing in the background could be a culprit or some of the fancy software functionality that Samsung cook in to touchwiz. I generally don't have anything working or syncing that I don't use.
Might be worth going through all of your settings one by one. That's what I did when I first got the phone.

I'll give it a shot , how does your battery life seems to do? also, do you use power saving mode ?
At this moment in time I've had 2 hours 44 minutes of screen on time and I've got 53% battery left.
The majority of that usage has been on WiFi though and I do have auto brightness enabled. One thing I have noticed about the s7 screen is, it is very good quality and incredibly bright. I have spent a good amount of time tweaking the auto brightness so the screen isn't any brighter than it needs to be in various light conditions.
I was suffering from rapid battery draining and the phone getting overly warm when I had Google Chrome installed. I've removed it, and it has taken those issues away completely.
I have come from a nexus 6p and don't miss the extra 500mAh of battery to be honest.
3hr 28 minutes of screen on time now with 43% battery left. Still on WiFi but have been playing a bit of order and chaos 2, reading the news, browsing forums and general Internet surfing. I don't have much on in terms of push notifications other than Gmail and have my Samsung Internet app syncing and some stuff related to my Google account.
If it's of any help at all, my phone is on the 3 network in the UK running the stock 3 branded firmware.
