[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] snake2332:
Ya, probably overnight is the best test for me since I use the tablet sporadically quite a bit during the day. I will get some stats but it's going to take a few days. I read a thread that I can't find now, but it was someone smarter than I saying how forcing the cpu to stay awake doesn't use much power since the cpu is very efficient. I charge my tablet and phone daily anyway so I will probably keep using WakeLock.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] snake2332:
OK I have some results from 37 hours of use, almost all of which had WakeLock running (I installed WakeLock when I had 91% battery left after about 2 hours of on-and-off usage after a full charge, so 35 hours of WakeLock running on the PARTIAL_WAKE_LOCK setting).

Basically, it uses just under 1% of battery life every hour. Two nights ago, the tablet was asleep for about 6 hours. It went from 29% to 24%. The night before that, it went from 84% to 80% in about 5 hours. Earlier today it went from 19% to 16% in 4 hours.

Battery remaining: 16%

37 hours since last charge.

35 hours of WakeLock running.

6h 45m of screen-on time, mostly at 10% or 20% brightness

50% of battery use was the SCREEN

35% of battery use was WakeLock, with "stay awake" showing 1d 10h and change

I haven't had enough time to test it with WakeLock turned off, but in the 4 hours since this morning it lost 2% of battery life. Last night, in about 6 hours, it lost 3% of battery life. So it is pretty close to 0.5% per hour without WakeLock. I froze Facebook & some Samsung apps to keep them from doing hundreds of wake-locks all day long. Stupid Facebook anyway...I have it set to never refresh and never notify, yet it still has 100 wake-locks an hour. Blech! If it wasn't for the convenient "login with facebook" crap built in to every app, I wouldn't even use the Facebook app. Well I have frozen it now, so I'm guessing I'll have to log in to wastebook manually via a browser now whenever and app requests a login.

Anyway, I still got around 2 days of use out of the tablet with WakeLock active. I am not that picky about the slower wake-up time though, so I am probably not going to use WakeLock. However, if the longer wake-up times bug you, give WakeLock a try. It really does work.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] DeBoX:
Is your wifi on?

Power savings mode on?

LTE or Wifi version?

I'm starting to have issues with battery as it is, haven't installed wakeLock. My note LTE seems to drain on average 1,5-2 % of power per hour, even when it's not being used.

Did a test , full charge and left it , wi fi on, but didn't touch it in the mean time , so screen off . after 14 hours it's down to 80 %. I.e 14 % of standby. Is that normal?

anyway, would be nice to have a comparison wakelock vs no wakelock
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] snake2332:
Wifi on

Power Savings off

Wifi-only model

20% drop in 14 hours of standby is pretty bad. What process is using all that battery?
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] DeBoX:
Android system, can't seem to get more info then that, been playing around with battery stat apps, but so far not much use. The standby time is killing me on average with ZERO use I only get 2-3 days of stand by ( tested over the weekend. Compared to my Ipad 3 that lasts a week or two without juice!
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] snake2332:
Hmm ya I don't know what Android System is doing that kills your battery so much. Sorry I'm no help.

I know what you mean about the iPad. My daughter hijacked my iPad4 and plays games on it. I often see it with 25% battery left with over 10 days on standby, 11 hours of screen-on. Gotta hand it to Apple with some stuff like battery and touchscreen response time. I just hate iOS too much to bear.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] bpt888:
Hi guys,

The only way to know which app is using up juice even when the tablet is asleep, is to use an app that monitor wake locks (BetterBattteryStats) and see if the tablet wakes up in between sleep cycles. I know my S2, S3 and Note 2 phones had so much bloat that caused wake locks during sleep cycles. After rooting the phones, I was able to freeze apps that I don't need running (bloat) and the wake locks stopped and battery life and response time increased dramatically. Custom roms and kernels just made android even more efficient down to voltage usage levels. You can also use the stock battery stats app to see if your tablet is waking up, check to see if you are getting blue ticks/bars during the time your tablet was supposed to be asleep. You want it to be clear with no blue bars (less disturbance) when it is in sleep state.But the stock app doesn't tell you which app is causing it but BetterBatteryStat does. That's what I'm using.

Also in comparison to the iPad, android has a built-in media scanner app that scans the micro sdcard for any changes and new files at certain intervals. This can cause a battery drains too if it is waking up during the sleep cycle. But it's a good trade off since I prefer to have the extra storage and option to install/backup apps and files with it. No iTunes needed EVER. Some custom roms disables the media scanner app or have it start only on boot-up and some changed the intervals to be longer but not during sleep state.

Hope that helps. Hope there will be more custom roms coming soon. So far I'm enjoying the experience and the hardware is great.

Cheers.

I am getting ready to install Lecture Notes, what does this setting do to it?
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] EpicDom:
I literally JUST got my tablet. It updated itself once and then that was it. I tested youtube briefly, then continued to do something on my computer. Came back and when I turned on the power button my lock screen was gone. It was just blank. However, my screen kept timing out as well so I couldn't do anything to get past the lock screen. I managed to restart it by holding down the power button but I'm kind of already concerned about this tablet. I wanted to upgrade from the previous one but I'm not getting a great impression.

I have a xperia x2 phone and it was working great with some midifications on it. but suddenly (without any events) its camera went crazy and it just focuses now! (Pressing it does not shoot or launch camera app.) I hard reseted the phone, updated with SEUS and even gave it to a repairman but it's not fixed yet.

[JAM, MDA Compact, S100 General] sekinoss:
Hi all. I've connected the xda (with WLAN card) to an adhoc net at home and was able to browse the net/connect around (via broadband through a gateway comp). Now I want to hook it up with a laptop (doesn't have wifi) as a wireless adapter. How exactly do I connect the two? Is it by "wireless modem"? Any pointers appreciated. Thanks.
[JAM, MDA Compact, S100 General] oltp:
Yep,

You need the driver & usbmodem_dialer. Lucky you I uploaded it a week ago to the ftp under usb_modem. It contains the inf for the laptop, the dialer & a document with the steps to follow :-)

Regards, M
[JAM, MDA Compact, S100 General] sekinoss:
Hi. Thanks for the advice. But I'm not trying to dial GPRS as internet in the PPC is already provided by the SD WLAN card. I'm trying to connect the laptop w/ the PPC so that it can use the internet in the adhoc network. Can it work in the setup? Also, Im assuming that the "wireless modem" software in PPC has to be running? Thanks!
[JAM, MDA Compact, S100 General] oltp:
Just follow the document, including the start of the wireless modem program. I think it will work with wifi as well, haven't got a wifi card yet. Maybe Santa can arrange one.

Cheers, M
[JAM, MDA Compact, S100 General] sekinoss:
Well, I tried that and it didn't work. Error 777 or something. Can't connect. Thanks anyway. Seems that the whole thing is suited for GPRS connections. Tried several times on my laptop but it timed out.
[JAM, MDA Compact, S100 General] oltp:
Take a good look at the modem init-string. Sometimes I've to add a ,0
[JAM, MDA Compact, S100 General] sekinoss:
Done that (just add ,0 to the end of APN in the extra strings?) but still no go. I'm really confused now. Queried the modem and it seemed to respond just fine. As I'm not going to use the GPRS at all, what should I put in username, password and APN? Also, what about "preset GPRS" in wireless modem? Thanks.
[JAM, MDA Compact, S100 General] oltp:
Frankly I don't know, I'm a gprs user and hoped this could solve your problem. Maybe it's only for gprs usage. APN & user/password are usually for gprs & I only had errors in 600 range.

Regards, M
[JAM, MDA Compact, S100 General] sekinoss:
Well, seems that I've hit a brick wall here. Thanks for all the help anyway.
[JAM, MDA Compact, S100 General] zonepericles:
im still with you sekinoss - this woud be a cool thing to do.

As a semi literate PC user I get to go to a lot of poeples places and sort their pc problems (for my sins!)

I've a friend who isnt internet savvy and has a wireless setup for his wifes laptop downstairs and his own pc connecteed to a modem(!) upstairs. Hes non intenet savvy and I want to get windows updates etc for him for the upstairs pc which is generally not net connected. I'd love to just take my PPC there with a usb lead and use it to get him on broadband wireless upstairs and update his windows machine properly. (He usually doesnt bother with the windows updates as they 'take too long' on a modem. Hmm.) Surely this would be a cool use of the PPC - I can't understand that there seems to be no software/method to do this sort of thing.

Ah well! :?: :D

Hi

I think I might have an issue with the battery on an xperia sp which I got a few days ago. When idle with stamina on it's loosing between 1-2% per hour. I've used Gsam and recorded some stats to show what's using up the battery when the phone is not in use. Hope it makes some sense :)

loosing ~2% per hour phone in idle screen off

Stamina on, GSM only

Tried airplane, not much difference

Tried Stamina off, no difference

Charged to 95%

61% @ 10:16PM

34% battery use - of that

screen 56.3% (1hr 47min)

phone radio 6.5%

wifi 3.7%

apps 33.3%

TOTAL DRAIN ON BATTERY

-------------------

19% screen (avg 0.18% per minute)

2% phone radio

1.2% wifi

11% apps

____________________________________________

13 HOURS IDLE LATER - 17-20% BATTERY GONE

____________________________________________

44% @ 11.04AM(QUICKLY DROPPED TO 41% in around 2

minutes)

51% battery use - of that

screen 49.8% (1hr 48min)

radio 13.1%

wifi 7.4%

apps 29.6%

TOTAL DRAIN ON BATTERY

-------------------

screen 25.4% (WHY THE INCREASE of 6.4% when OFF all the time?)

radio 6.6% (+4.6%)

wifi 3.78% (+2.58%)

apps 14.8% (+3.4%, not sure why, stamina turns off all apps?)

6.4 + 4.6 + 2.6 + 3.4 = 17%

Why are these using up so much power in idle with stamina mode on?
[Xperia SP Q&A, Help & Troubleshooting] heross:
Hello,

remove your simcard, reboot, got in to flightmode and let Wifi enabled.

now let phone unused for 8hours. its all Ok then accu should drain only 0,05%/h.

This is my XSP which i use only as alarmclock an every day 1 hour as Musicplayer.
[Xperia SP Q&A, Help & Troubleshooting] spix123:
I have tried without the sim card but it didn't do anything.

I notice in your screenshot though that there is no connection to 'mobilfunknetzsignal' ... mine is there even when the sim card is out, how did you get rid of it?
[Xperia SP Q&A, Help & Troubleshooting] heross:
You must enable the flightmode under "settings->network->more" .

and then please install BetterBatteryStats to see if you have wakelocks and your device go in to deepsleep after turn of the screen.
[Xperia SP Q&A, Help & Troubleshooting] spix123:
Ah yes.. I tried flight mode one night and it still lost 15%

I have also used wakelock detector and it says phone is in deep sleep 99 percent of the time but still the battery is draining 1-2% per hour

Right now the battery is 27% down from 44% 2 hours ago... and I have hardly used it. I'll recharge and try again without turning screen on at all and see whats using it up.
[Xperia SP Q&A, Help & Troubleshooting] spix123:
Is there any explanation why the screen used 6.4% of the battery overnight when it was off all the time?

I'm too having about same problem..and am really interested in answer/solution,,,

Please, anyone?
[Xperia SP Q&A, Help & Troubleshooting] spix123:
I think I have fixed it but not sure. Phone was charged 24 hours ago to 99%, now its 94%. Definitely not using alot of power with stamina mode now but the screen was only used for 5-10 minutes, I've yet to test if it acts the same after screen has been used for a long time before going idle.

What I did was run phone setup again and update all apps
[Xperia SP Q&A, Help & Troubleshooting] spix123:
Now 88% after 40 hours, screen on for 25 minutes. Xperias battery monitor and gsam show completely different usage, android system takes up the majority in the xperia one but only 10% in gsam (under apps)

I checked wakelock detector and something called 'syncloopwakelock' was on for 4 and half hours. Is there any way to disable this? I already have auto sync in settings turned off.
[Xperia SP Q&A, Help & Troubleshooting] mrjraider:
A phone is meant to be used. Using it only from time to time to have as much standby time as possible is just a waste of a good phone.

I can get two days with heavy use. A lot of music, whatsapp, facebook and XDA Premium app..
[Xperia SP Q&A, Help & Troubleshooting] spix123:
I know, but there was a clear issue before as the battery was draining 20 percent overnight reducing the time I can actually use it. I was getting 5 hours screen on time one day, and only 2 hours the next. Just trying to make sure it has stopped, seems like it has :)

Would like to solve this syncloop thing though. I have no interest in syncing any accounts as I don't use them.
[Xperia SP Q&A, Help & Troubleshooting] mobm93:
Simple fix

Change your rom, stock rom eats so much battery and has so many bloats, apps keep running in the background all sony apps.

MIUI is on jellybean and it gives me average of 1 day 20hours on normal use with wifi always on and sim card inserted..texting call and stuff
[Xperia SP Q&A, Help & Troubleshooting] spix123:
Problem has returned, woke up today to find battery under 50% and it was at least 75% when I went to sleep. Wakelock detector doesn't show anything and says phone was asleep all the time. Sony's battery graph though shows the phone was awake most of the time, but I can't find the cause in GSam or wakelock detector.
[Xperia SP Q&A, Help & Troubleshooting] heross:
i think i have a idea. it can come from WiFi. there is a bug in all android 4.1. Set Wifi to allways on and deactivate/delete LocationBasedWiFi app from sony.

you can found it with BetterBatteryStats under Process.
[Xperia SP Q&A, Help & Troubleshooting] spix123:
Some screenshots
[Xperia SP Q&A, Help & Troubleshooting] heross:
in this screenshoots the problem is not shown. When it comes from WiFi driver it is not a app that drain the accu, but a process.

The Line with awake in history details you can ignore, its buggy in 4.1.
[Xperia SP Q&A, Help & Troubleshooting] spix123:
I have searched through everything in Wakelock Detector and only process I found with alot of time is syncloopwakelock which is 4.5 hours. But this was already about 4 hours when battery was 85%

If I buy BetterBatteryStats will this show the problem? As you an see it drained at slow rate for 2 days then suddenly started dropping faster yesterday. I made no changes to Wifi settings, it is always on ... and I use Stamina mode.
[Xperia SP Q&A, Help & Troubleshooting] heross:
Yes BBS will show the problem as "wifistatemachine", if the error should really be come from. you must not buy it, search on XDA for apk.

but if it come from your syncloopwakelock then i can not help.

Holy crap

I charged the phone to 96%, used it for 30 min (down to 92 percent) then went to sleep. Woke up and it was 28% and kept dropping !!! I've checked BBS, Gsam and I can't find the cause... again. After uploading these SS its at 12 percent.

No, the only apps I have installed are the battery ones to try solve the problem and 2 or 3 games. Everything else is stock.

I haven't made any changes since the screenshots before (where the phone idled 40 hours and lost only a few %) Now it idled only one night and lost almost all of it.

I do have auto brightness selected in the xperia menu though, but I don't see why that should cause a problem

Are you sure its surfaceflinger causing it? Not sure what the blue/red bar means under it.
[Xperia SP Q&A, Help & Troubleshooting] pec0ra:
I don't really know but our device seems to have problems with autobrightness. Now I'm using manual.

In my case the android system drain from battery settings was caused by surfaceflinger. If you hit the refresh button you can see the real name before it loads the name 'android system'. Btw I didn't have any wakelock in bbstats.

Really doesn't make sense, anyone got an idea what could be causing it?
[Xperia SP Q&A, Help & Troubleshooting] heross:
i think surfaceflinger is not your problem. my surfaceflinger is on the sixth, but with same usage time. I am still of the opinion that the cause is the wifi. Although not WiFiStateMachine, but something can not rest your WiFi.

see screenshoot from yours compared to my XSP. The only tip from me search and deactivate all bloatware from Sony and Google. Is ok, then turn apps one after another and see on wich app problem come back. You have to find out what hinders your WiFi at rest.
[Xperia SP Q&A, Help & Troubleshooting] spix123:
Interesting, but if my wifi is connected all the time why was there massive increases in my battery temperature at certain times (see third picture of GSam) It lines up with the the 'awake' moment shown here. If it was wifi wouldn't it drain at constant level?
[Xperia SP Q&A, Help & Troubleshooting] heross:
not necessarily. The consumption varies with the required transmit power.
[Xperia SP Q&A, Help & Troubleshooting] spix123:
What do you recommend I do now? Phone has just finished charging.

I decided to uninstall GSam, BBS and Wakelockdetector just in case one of them is causing it.. will I try airplane mode with wifi on similar to yours?
[Xperia SP Q&A, Help & Troubleshooting] spix123:
I have completely disabled wifi. If the problem is fixed then it's 100% caused by wifi and I will try locate what won't let it rest.

The reason I'm not really sure its wifi is because of this screenshot. It was on all the time here also but drained very slow for first 2 days
[Xperia SP Q&A, Help & Troubleshooting] heross:
No.i have only no SimCard in XS, but WiFi is enabled.

go to WIFI/Advanced and select Keep WIFI While Screen Sleeps, set to "Always" and test. then set to "Never" and test. (My state is set to "Never")

if nothing help do a factory reset or use a custum rom without bloatware.

[Xperia SP Q&A, Help & Troubleshooting] ngoralph:
my guess would be that wifi is on but phone cant connect to wifi and searches for it non stop i guess
[Xperia SP Q&A, Help & Troubleshooting] spix123:
The connection has never dropped once when the phone is in use, I'm pretty close to the router so don't think that's the problem. I must say the wifi range on the sp is pretty shoddy though.
[Xperia SP Q&A, Help & Troubleshooting] spix123:
The reset didn't help. It's behaving the same as the first post in the thread (losing about 20 percent over night)

Battery apps still report the screen using the most but again it was off all the time so it couldn't have been. I think something is using it that the apps don't detect therefore it just adjusts the percentages of what it can to make everything add up.
