Samsung Galaxy S II :: After ICS Update Android OS Killing Battery
Jul 20, 2012
I've been noticing my battery draining pretty fast. I've had the phone just over a month and days when I'm at work all day, maybe do some surfing on my lunch or breaks, but nothing to excessive and my battery is down to like 35% when I get home. Before I was going under Settings->Battery and I noticed "Screen" was the number one offender for draining my battery. Which makes sense, it's a bright display and powering it takes a lot of juice. I don't know if it's coincidence or not, however, it's when I started noticing it after installing ICS. Now "Android OS" has replaced it at the top, by a LOT. Here is a list of my top five
Android OS: 58%
Screen: 18%
Cell Standby: 10%
Phone Idle: 7%
Android System: 2%

I had my Samsung Galaxy s6 G920F one week ago, nothing to say about the phone, amazing battery life. I always plug my phone to charger when I'm home after work, I don't leave it plugged while I'm sleeping. During the night the phone consumes like 1 to 2% battery. I shut down wifi, bluetooth and data during the night. Two days ago I installed Adobe acrobat reader, and disabled some built-in apps which I don't use (Google play music, google newsstand, chrome, hangouts, google+ and skype). Before I go to sleep my phone was 82% battery. When I woke up, my phone was 64% battery. I thought that the issues with Samsung/Android battery life are over with android 5.1.1 and galaxy s6, but in fact no.
I found that a clear cache can solve my issue. I did this and battery drain stopped. Yesterday night, I decided to make a full wipe/clear data, and clear cache. I reinstalled same apps that were on the mobile before, and disabled the same built-in apps. Phone was at 74% when I went to sleep. This morning, my phone was at 52%!!! So I uninstalled Adobe Reader, and activated all the apps that I disabled before, restarted into recovery and cleared cache. Now the issue disappeared again, but I wonder if this will not appear again when I charge my phone to 100%.

A co worker of mine has a S6 and is having trouble with the screen randomly coming on and going off. As a result I think it's killing his battery. If I look at his battery stats the screen is sitting on 32%, Messenger is at 16% and Facebook is 13%. That's the three biggest readings and all others look normal. What's happening is that the screen will just pop on by itself, stay for 4 or 5 seconds, turn off for about 5 seconds, then come right back on and stay for 4 or 5 seconds. The cycle keeps repeating itself. He says that it will do this sometimes for 4 or 5 days in a row, then not do it for maybe close to a week, then it comes back.
I thought he might be getting some sort of reminder from something that is turning the screen on but then it doesn't make sense that it goes right back off again. Since it's not my phone I can't get any screen grabs or anything.

Media server is killing my battery, and fast. I mean a 40% drop in 2 hours yesterday while phone was on sleep with wifi and mobile data disabled. I'm in the UK using S5 900F standard model on kitkat 4.4.2.
Since then I have:
- unmounted Samsung SD card (it only had a few photos and apps on it, had it a week)
- force stopped all "media apps" despite dire warnings as to world ending if I do so etc, and cleared data
- repeatedly cleared cache
- rebooted phone in safe mode and am monitoring. Battery drain is better but media server is still the main culprit at 27% (down from 51% but still..)
I can't keep it on safe mode all day as it's highly inconvenient.
Phone is unrooted, 3 months old so warranty is important. I can't download mediaserver killer etc
I am unable to isolate which media files are causing this or why. I thought it was the SD card which I added recently but it's a Samsung and should work, plus the problem hasn't disappeared after removing it.
I haven't downloaded any apps since the problem started, or downloaded any media files. I have no games on the phone. A little music, Spotify premium (force stop and now disabled by safe mode), 50 photos. Before the mediaserver problem started about a week ago, battery lasted 1 1/2 days at least. I'm not a heavy user of online media (bit of YouTube but never download or watch movies on my phone).

Okay. I'll see if this posts. I am using Android 2.1 and AT&T told me I could "easily" upgrade to Android 4 using KEIS. I downloaded the program, updated to Version 2.3.2.12074_13. Installed okay. I connected and got the message "device not supported by KEIS 2."

Whenever I try to run the android update it says "Searching for server" then report, "Server connection failure". This goes running though either wireless or 3g connection. The SII works fine downloading/uploading everything/everywhere else and on any connection, it has me baffled. It has worked before as it did a couple of updates when I first bought this really great phone!

Is this a precursor to ICS or what is it? What has this firmware update done for me? I can't notice any difference? ICS for Orange soon perhaps?

I have been having intermittent problems with fast battery drain before and after upgrading my Samsung Galaxy S2 to ICS. In fact the reason why I upgraded to ICS is to see if it would fix it. Most of the articles I have read on the net are about people who have problems after the upgrade, which is why I am left puzzled. Often I leave my phone unplugged during the night and it has almost completely drained by the morning. here is some more information:
- In the battery stats my Android OS percentage is always high (60% +)
- I am always careful with trying to preserve battery life, for example setting the backlight to minimum brightness and closing applications which are running in the background
- I have gone for months where the battery has been fine, but cant seem to spot a trend

Fully charged when i went to bed, woke up 8 hours later and it's down to 52%. One hour later it's down to 45%. Has the 'wifi bug' been put on my phone with v3, or does it just have terrible battery management?

the last few days my battery has not even come close to getting me through the day. No new apps. I look at my battery usage and find that Phone Idle is the largest user of my battery. While researching this I find tons of folks who are like "that's normal", but it is almost always even with cell standby. My usage is as follows right now (and this is what it's been like for the past 3 days): phone idle: 37%. Display: 23%, Voice calls: 15%, android OS 10%, Cell standby: 8%. Those are not the numbers anyone else I've spoken to that is running android is seeing. They are seeing phone idle running even or just below cell standby. I'm off battery for 8 hours and down to 25%. I won't make it home before I have to plug in the phone, and for the last 6 months my battery has been making it all day.

I recently bought this generic phone pouch with a belt clip and every once in a while the battery and phone will be completely dead. The pouch covers the phone entirely except for the top which is open and I can slide the phone into the pouch from the top. I am sure that the pouch does not have a magnet ie the phone is not coming out of sleep while in the pouch. Even in Airplane mode and all wireless devices turned off the phone dies. I cannot understand and believe this. The pouch is relatively tight and the only thing I can think of is that somehow the side camera button and/or rocker volume switch combination is being "pressed" while in the pouch and causes the phone to turn on and die.
If the phone battery doesn't die the battery is down by 40% with no use at all during the day ie I always use the phone in Airplane mode while at work. I do not answer the phone while working.What could be causing this? I can just go buy a new pouch but this totally does not make any sense to me.

I've been having a problem the last few days. My GPS icon stays on continuously and ***** the battery dry. I've seen issues where it will stay on for 12 hours. Even though I thought that was abnormal, it would eventually turn off and resume normal function.
Now it is just running non-stop and the only way for me to stop it is to manually turn off the GPS.

Just got my S2 replacement and upgraded to .428 before I even did the swap devices with the DM, and now this phone is set up just like my last one with all the same apps and it is absolutely killing the battery. I dont know what it could be, I have went through and checked the obvious to make sure it was all good( brightness, 1XEV only, no apps running in the background or updating, wifi off etc). I've lost 10% in less than 20 mins after a full charge. Maybe delete all the apps and reload them one by one again?

About four hours ago Facebook messenger started really killing my battery. I haven't even used it in about a week and a half and suddenly it just has gone wild. It's not using data or WiFi but in those few hours it's used 20% of my battery.

I was super satisfied w battery life of my new iPhone 4 the first two days and until it ran down to 1%. After that I think it decrease too much and almost 1% per minute when surfing. But one thing I might be wrong is killing apps in the multitasking menu. Will that increase or decrease battery life? I am thinking maybe it will decrease rather since it is more of an effort to reload the program then having it idle in memory. Am I wrong and what else could affect battery life? I have fixed usual suspects, brightness, location services and push services.

Facebook has recently enabled autoplay videos in your feed as a default. Facebook autoplay videos are neat feature to have video's running as you are reading your news feed but it also runs up your cell modem data usage as well as burns your battery.
Now I have several ALS Ice Bucket videos all playing and downloading when every I open up Facebook. I have been noticing that my data was going up a lot this month. After reading a article that everyone is posting their ALS Ice Bucket challenges that it is impacting people's data plan and battery are getting killed by Facebook with this new Facebook Autoplay video default.
Also, for extra battery saving tip in your Facebook setting disable Messenger Location service. How to disable videos from playing automatically in your Facebook news feed for both the mobile app and on the desktop.

Noticed battery skipping percents after the Android 4.3 update?
When my battery is fully charged it goes from 100% to 98% just from texting, but then it will go down percent by percent after 98. Still holds a charge as it did before the update, but I'm stumped as to why it skips 99%?

I have SGS2 Android 4.0.3 (Ice Cream Sandwich) updated via kies.
In the contacts app, Im sure there used to be a way where by if you were syncing your facebook account, status updates and media would appear in the contact (In Contacts). This doesnt appear to be the case anymore.

Can I use my PC/Mac to buy and install an application from the Android Market? If so is their an idiot sheet on how to get the app off the computer and onto the SGS2?
The reason I ask is that I'd rather use my computer to buy an application rather than use my phone.
