Samsung Galaxy S II :: Battery Drain From Mail App
Jul 2, 2011
I've only had my SGSII a week or so but have been very unimpressed with the battery life I've been achieving - not even a full working day.I've been trying to work out what's going on, but this morning things really seemed to come to a head. I'd charge overnight but within an hour and a half of disconnecting the phone almost half the charge had gone & the back of it felt very warm to touch.
Looking at the battery stats and using the Watchdog program it looks like the Samsung Email app is to blame. I also saw the phone was marked as 'awake' much of the time, presumably due to a partial wakelock from the Mail app (battery history in Gingerbread doesn't seem to actually have partial wakelock as a category but this certainly looks like it). I've got three accounts setup in it - 2x Microsoft Exchange and 1x IMAP. Refresh times were initially push (MSEx 1)/manual (MSEx 2)/15 min (IMAP). I've tried changing them all to 15 min or to manual but it doesn't seem to improve matters. In case it is of relevance, the MSEx ones are imposing device & storage encryption as part of their policies (I've no choice in this).
I've used my Galaxy S6 for two months through work and I like it... sort of. Lag spikes are normal, compared to my Moto X 2014 which runs smoothly. However, this is not what really bothers me.
I've set up Knox to work with my corporate Exchange server. The mail app has been set to manually sync, as push and timed sync drained my battery incredibly fast.
Even now with sync settings on manual, the phone chews through at least 5-10% per hour. As soon as I disable my email connection or disable Knox, the battery drain stops.
Is there an alternative app that can be used in Knox? I've tried Outlook but it doesn't allow me to specify a certificate or enforce SSL.
I would prefer to use something other than the built in email app, as that seem to be the source according to other forum posts.
Even better: is there any way of plugging the battery drain without loosing Knox email capability?
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
I installed a 32GB Transcend SDHC card into my S2 around 2 or 3 weeks ago. At first it was all good, but then last week, I started noticing the battery started draining quicker than normal. Usually, I can get around 10 hours of use, but this went down at first to 8 hours, then rapidly plummeting to 6 then 4 hours. The shop where I got the phone from advised that it could be software corruption or faulty battery, and they were happy to send the phone off to Samsung to get it checked out, but I decided to run a few tests myself. I bought myself a genuine Samsung high capacity battery (I need it anyway), and installed it. I noticed that the battery drain was still happening, so it was not faulty battery. Then I decided to try removing the SD card.
I've updated my Neo to ICS 4.04 recently and since then apart from LED notiffications not working the stock Email app (not gmail) sync is not working. It was working earlier in GB. I configured my gmail using the email app and set the refresh interval to 1 hour but it never syncs or refreshes. It worked perfectly in GB. SONY fix this issue as I'm missing some important mails.
2. The media server is draining a lot of battery without me listening to any music. I really don't know why that's happening. I did repair my phone after ICS update but still this issue. I don't listen to songs on my phone as I have a music player but media server consumption is around 10 % and that pretty high.
Ever since I've left the location on (before I always left it off and just turned it on when I used the GPS), I've noticed a big drain on my battery. I only get 2 hours SOT as opposed to around 5 like before.
I have a Verizon GS6 running 5.1.1. A few days ago there was an update for the ANT Radio Service and ANT+ Plugins Service. I'm sure others got this update too. I'm not sure if it's related, but all of the sudden my Bluetooth is killing my battery. It won't let my phone sleep. All I have connected is a Fitbit, which I've had for 4 months and never had an issue like this. It's killing my battery and the only thing I can do is turn off Bluetooth.
I just bought a Galaxy S6 yesterday, and something weird happened. I had it charged to around 75% yesterday in the evening, I switched it off, and when I came back this evening (about 22 hours later) and turned it back on, my battery was dead (0%). It refused to start at first, and only turned on with the charger plugged in.
Since I just got the phone, I had very few apps and accounts running aside from Google and Samsung (no email account, facebook or anything like that).
Is it faulty? I am going to try again this evening, but I would like to know whether I should consider bringing it back anyway...
i have a problem with battery drain the phone is emty after a half day. im on AOE3 firmware version.i remember reading somewhere the this is because of flashing twrp? and needing to flash stock recovery.My question is is this true? and where can i find the AOE3 stock recovery?
On my G3, when I fully charge the phone, it would stay at 100% for a VERY long time before dropping down to 99%. The most I've gotten out of the 1% before was about 25 minutes of SoT.
On my S6, once the phone is fully charged, it seems to drop to 99% very quickly, within just a couple minutes of using the device.
What causes this difference between the two models and does your S6 act the same way as mine?
In the screenshot you can see from 12:00 till 13:00 I wasn't using my phone and got a 20% battery drop, I went from the office to home. See screenshot.
I have a feeling after rooting the device, it gets battery drained from SSP wake lock. Device deepsleeps 50% and 50% awake because of that SSP wake lock.
There is no information about what and why. I disabled all motion features, deleted shealth. Turned off Location services.
The same happened to another S6 from a friend, and a S6 edge. All 3 devices have ssp wake lock problem.
I'm running stock, straight of the box, no root.And yesterday for example I went from 100% to15% in 7 hours....and this is at work with my phone sat on my desk not being used.Settings is saying that Google services is killing the battery, that and Android OS.Google services has a 'Stay awake' of over 3hrs and 'Mobile radio active' of over 2hrs All other apps also have a high 'Mobile radio active'Is this a bug in 5.1.1?
Second issue: How hot does this phone get!?Any usage of more than a couple of minutes with the screen on and its warm, getting towards hot.Use the camera for example and it gets hot...borderline too hot to touchFor me the main issue is the crappy battery life.
why the battery drains so much when taking it off the charger and prevent it from happening. When I took it off the charger it immediately jumped down to 98 and then within a minute jumped down to 95.
First of all, I know a lot of people who only has Location on all the time just for their Weather widgets and apps to refresh your weather information, you don't need your Actual Location to have that, you can simply turn that off on the weather app or widget and enter your city or cities manually, it will give you the same information the only difference is that it will not ping your location all the time to do it.
I have tested all settings and I have found that the one that does the job while preserve the battery life the most is the Wifi and Cell signal only option, in other phones it's called Power Saving Mode. I've been using this option all the time for the past couple of months and it really uses very low battery, barely noticeable, this way I keep my location on to be able to use the locate device and other location services. I only change to high accuracy (GPS, WIFi and Cell) for my daily 5k runs or if I need to use Google maps or any other Maps apps. There are people who use GPS only but I've noticed that it increases (obviously) the gpsd service in my battery stats and it drains battery a lot more than Power saving Mode.
Location History is not needed for the Location Services to work, this is just a Google Service to enable other features. Take a look at this information. Google’s Location History is Still Recording Your Every Move.
Until mid April, when we had 2 separate options, Location reporting and Location History, I had location history on but Reporting off as it was besides the Screen, the number 1 battery drainer on Android, and I frankly didn't want to be "reporting" Google all my moves, but now that they incorporated both into just one setting, I just prefer to turn it off.

Whenever I'm at school my battery drains exponentially. Today I was writing a final exam and had my phone in my bag for 3 hours, in that time the battery dropped from 80% to 45%. I don't think my signal is the problem because I have 3-4 bars of lte at all times when I'm at school. As for optimizations I'm doing most of the tips erasat provided in his thread. I am connected to wifi too. The battery stats on the phone doesn't show anything is draining my battery. What could be the culprit?
Also this only happens when I'm at school not anywhere else. This has been going on ever since I got my s6 (3 months).
On at&t so no 5.1 yet. All of a sudden my battery plummets overnight. Went from 80% to 33% this morning. Nothing out of the ordinary in terms of app usage I can see. Battery has been on the ok side since launch can stretch to 24 hrs with 4 sot max. Also getting the camera issue when it launches and looks like surface of a lake periodically. Also, seems hotter when charging... Could this be a dud this far along? Bought on launch day...
Normally the battery drops about 20% per night. Occasionally it's kind of hot/warm and more than 50% dropped. I used an iphone 5 before S6 EDGE, and it dropped around 10~15% per night.Where I sleep has a good 4G signal and WIFI signal. I haven't turned on the "don't disturb" option when I sleep. Also, due to the unacceptable quick power consumption, I have turned on power saving mode all the time, although this makes switching apps slower.
I am using unlocked Samsung Galaxy S5 G900F model for 1 year. It working fine. But for 3-4 months I cannot keep my phone on overnight. It drains battery to 30%-40%. I have tried all possible solution like:
kept brightness to minimum WiFi, mobile data, Bluetooth, GPS kept off stopped unwanted services like FB, S finder, etc from App manager.
I mean all possible options.
It shows that Phone radio and network are draining my batter (as shown in attached images) Also how can screen brightness drain battery when kept idle screen locked mode overnight? (as shown in attached images). I have attached screenshots when I found 69% battery remaining in the morning (kept at 100% at night)
Note 1: During day battery performs normally even with WiFi and data Note 2: Even when kept in ultra power saving mode overnight it drains around 20% battery
i have a S6 without root and all stock . I have a very big battery drain of Google Play Services , i already turn location off , sync off , search in many forums and turn off many options of google , disable many apps of google , etc , but i still having a very big battery drain of Google Services ( i updated too with a apk to the last update ) ... I only find a solution and is with app ops , but i am not root , and seems that all app ops need to be root
Had my new S6 for a few days and ive been having problems with it and im thinking it's unacceptable. Occasionally when im browsing using chrome, the webpage will crash and would ask me to reload the page. Not sure why. Also, i notice when im browsing or in a news/sports app etc, when reading the scrolling would appear like 'choppy' and stuttering. On top of that the battery seems to drain somewhat quick. Also some apps like gmail have occasionally crashed.
I've tried everything to stop this, i.e. use nova launcher, turned brightness down, restarted and cleared my cache but i cant get it to run smooth. I had the htc m8 and I never recalled it doing this.
My phone is one of the "not so good battery" variety, so it needs to be charged mid day every day.
Today I couldn't go to work due to hurricane and thunderstorms near me. so I sat back and played some N64 Zelda for 2 hours and what do you know, I'm at 60% with 2 hours of SoT... probably the best SoT I've ever gotten (I'm guessing I'm gonna have 5 hours SoT today? estimate?) but when playing something like dead trigger with the same exact Bluetooth controller the battery drains much faster. (I would say the same battery wasted in half the time)
Last night my fully charged S6 Edge was taken off the charger and left next to my bed. When I got up 7.5 hrs later I was very surprised to see that approx half my battery was gone and all due to the stock email sync. I have unlimited data and didn't bother changing the sync to longer intervals rather than push. I have obviously changed the sync interval.
I recently paired Ankovo headphones to my Galaxy S5. It has resulted in a massive battery drain on my phone (I had to factory reset to get the drain to stop). Is this a known problem and is there anything I can do to keep these devices paired up, or do I need to cease use of wireless headphones?
Having issue where android system is consuming 35+% of the battery? Looking at the stats it seems like one of the bundled services is keeping the radio on for 14/18hrs its been on.
I've used them before when rooting a previous phone. I have a problem with my new S6. I got it about three weeks ago, and I love it. The only problem I have is the incredibly short battery life. There has to be a problem with my phone, because I'll have a battery life of about 5 hours on a good day, but usually 2 or 3. The phone will get mildly hot, and all battery will drain rapidly. I will regularly lose ~40-50% in an hour after it starts heating up.
I've been simply dealing with it for a while, after a failed attempt to find a solution on Google. I regularly close my apps, and I even have powersaver on at all times now. Last night, I closed all apps, then restarted my phone. It was at 98 when I fell asleep. I woke up 9 hours later and it was dead. I have checked the battery info a couple times, but I don't ever see anything rapidly draining battery.
I posted about a problem with my battery losing up to 30% battery on reboot but got no answers so am hoping somebody will test their phone for meWhen my battery drops to just below 50%, if I reboot by pressing and holding the power button for about 8 seconds, on reboot, my battery has dropped to as little as 13%, even if there was 48% left prior to rebooting.I originally thought this was happening after tethering but it has turned out, it does it regardless of how much or how little I use the phone and even without tetheringI am on stock 2.3.4 XEU, manufacture unlocked and wondered if some kind soul would be kind enought to see if they can replicate the problem.It needs to be the 9100, complete stock and not rooted really as I am trying to determine whether it's a hardware issue or software issue.
