Battery overnight - ONE Q&A, Help & Troubleshooting

I am opening this thread not to complain about battery performance in general, as i find it stellar.
Still, when I leave the phone untouched overnight, I lose 1% per hour, which I find strange.
As you can see from screenshot 1 and 2, the phone has been idle 9 hours and has lost 9%.
I usually leave the phone with DATA SYNC, WI-FI, 3G and GPS on, as I rely on GOOGLE NOW.
From screenshot 2 you can see that GPS has never been active, only 3G SIGNAL and WI-FI.
From screenshot 1 you can see that 41% of battery has been used by ANDROID OS, followed by PHONE INACTIVE, WI-FI, CELLULAR SIGNAL IN STANBY, ANDROID SYSTEM and GOOGLE PLAY SERVICE.
Being GOOGLE PLAY SERVICE at 5% I do not believe this is the problem, even because 8as you can see from screenshots 5, 6 and 7) in Privacy Guard I have denied to GOOGLE PLAY SERVICES the WAKEUP and the KEEP ALIVE.
So, the two main drainers are ANDROID OS at 41% and PHONE INACTIVE at 15%.
In screenshots 3 and 4 you can see details about these two services.
ANDROID OS has kept the phone active for 1h while PHONE INACTIVE for 8h.
Is this PHONE INACTIVE that i do not understand: what is this? Does screenshot 4 means the phone has been inactive for 8h or that PHONE INACTIVE service has kept the phone active for 8h?
Anyhow, any hints would help.
Thanks

It seems that your signals (wifi & cell) are very low. I would bet that this is the reason for the drain.

no it is not that: I took the screenshot from the changing room where indeed the signals are very low, but next to my bed both signals are at maximum.

[Q] Battery loss 25% over night (8 hours), normal?

I disconnected my phone from power when it was at 100% before going to sleep. This morning 74% of power was left (after 8 hours).
"Cell standby" ate 40% and "phone idle" 35%. I'm in 5 bar coverage area. Is it normal?

i dont think so. i use almost no battery overnight unplugged with not so good coverage. im running stock atm.
I also use about 35% overnight. I started to systematically uninstall recent apps with no change so far. About 5% drain/hour. Weird stuff but also intolerable

Display is at like 36% when I get up in the morning, even though the phone has been idle all night. Then android system is like 25%

Probably different issue then mine. You probably have some reminders or someting lighting up screen or something at night.

Did you recently perform a flash (to a new ROM, a different one, or flashed back to stock JF6)? If you did, you'll need to condition the battery.
If not, you probably have some background apps that run all night.
EDIT: Ooops, nevermind.

I did not recently flash anything. I do have a bunch of background apps but if they were consumers they would show on a list, is not it. It would not be "phone idle" and "cell standby".
I'm in a similar boat. Ill drop around 20% within two hours. Display time is less than 30 minutes. Display down low. email fetching off. Running cognition 2.3 Tom
I've got a new battery on the way from att warranty.
Is it worth trying cpuset and tweaking?
Hope your battery life improves. I hate the mid day charge
Any chance you have wifi on? When I was running stock I would only lose a few percent overnight with it off. With it on though I would lose 20%+ easily.
Wifi uses battery more than 3G? In any event, without hijacking the OP's thread-I turned off wifi and it still uses about 5%/hour sitting idle with the screen off and locked.
However, what I did this morning: When arriving at my office-all I did was turn off something called "animation" in the display settings. I have no idea what you miss with animations turned off, but in about 3 hours of sitting idle, wifi on, I've only lost 2%. Not sure if I'm onto the problem..but will let it go another couple hours to check..then I'll turn the animations on again to see if that does anything.

I actually enable WiFi during sleep instead of 3G since according to posts here WiFi is using less power then 3G.
Thats what I thought..so turning off wifi is obviously not going to help battery life if you have a 3G signal. I don't know..I'm just killing one app at time but its tedious. May just do a factory reset-ticks me off to see the battery drain on a device that's already hard on the dam battery to begin with
I have started using cpu tuner to underclock my cpu when im not using it. Doing wonders so far. I am at 40% and have been using my phone normally for 10 hours 36 minutes

Woo first post--
Turning all data connections off will vastly boost your battery life. Not just WiFi but also 3G. On the stock Captivate you can do it by dialing *#*#4636#*#* > Phone Information > (Hit Menu button) > More > Disable Data Connection. Also check for SYNCing, stuff like Facebook, Twitter and Google syncing takes up a lot of juice since it repeats so often. I turn mine off unless I know I need real-time updates on a given day. On top of that, just keeping background apps from drawing CPU (i.e. having task manager to kill the ones that you KNOW keep running even though they're in the background) will help. I got ~24-36hr out of a charge through these three practices.
The next step for me personally was rooting the phone and taking out all the AT&T bloatware. This stuff loves to run in the background for whatever reason and killing it every hour is not going to help your battery life. So I removed all of it and reached almost 48hr out of a charge (low usage).
Turning off animations just takes away the smooth transitions between screens. I believe the home screen launcher (TouchWiz for stock Captivate) is actually unaffected, you still get smooth scrolling between screens. I'm using Launcher Pro and unticking the animations box in the Android settings only took out the menu animations, my homescreens are still smooth and fluid. Just that hitting the menu button makes the menu display immediately, instead of softly/smoothly, and returning to home is also instantaneous. I don't miss the animations, I like my faster AND more efficient.
If you've got the guts to play with your phone and really void your warranty, flashing to Froyo (2.2) and then optimizing everything you can about its power consumption will up the battery life even more. Today I used the GPS for a road trip, listened to music, spent 2hr browsing the Internet, made several phone calls, used the phone as a flashlight for an hour (pure white on screen) and after 24hr off the plug I'm at 50% battery. This phone + Froyo really is no joke, I've spent a couple days' worth of hours tuning so far, but once it's set up it's really satisfying. I can easily wring out 3 days from this phone if I don't go crazy with it.
Edit: If I let the phone sit still for 8 hours I lose about 1-2%. Not bad at all.
Reading around it seems that wifi signal and cell signal quality also majorly affect battery life. So if you're in a good location, you could potentially get much more out of your phone than if you're in a place with bad signal.
My battery life improved dramatically going to
settings ====> wireless and network ====> wi-fi settings ====> options ====> advanced
and changing wi-fi sleep policy to never. My default setting (Rogers) was when screen turns off. Made a big difference. Don't know if the default is the same on AT&T.

What do you mean? You battery life improved actually after enabling WiFi to be always on?
I think it's pretty funny how half of the forum swears they get better battery life with wifi on and the other half with it off.
I personally have never gotten better battery life with wifi on. I've ran stock, JH7, 3 versions of cognition, and now on Perception build 4 and this has never been the case for me. I've tried it out with access to different routers with varying amounts of signal and it still showed no signs of improvement.

[Q] [QQ]POLL - Are you happy with the battery life

Hello
I am reading a lot of different comments in the battery discussion thread. Its hard to tell how many people are happy and how many
hate the battery life. Some people have their phones on airplane mode to show of the lengevity and it really throws me off. Please vote
on the poll and make this simple. Do not post any screenshots or usage just a simple yes or no. Thanks Guys and Gals!
Says im not allowed to vote in the poll. Very happy with battery life

My buddy is coming from an iPhone 4, and so far he hates everything about it as much as I try to change his mind. He is more concerned with the screen-off battery consumption than anything. He swears up and down that if his screen is off 95% of the time (just quick reads of email/sms) then his iPhone 4 will easily last 3 full days while notifying him of sms/email/im/facebook/etc. I don't see how that's possible. He says all the time he would put down the iPhone at night on the 5% warning, NOT charge it over night, and it would always be alive for the alarm in the morning (without disabling any syncing). I don't see how that's possible. He basically believes that phones should not take hardly any battery when their screen is off, and he swears up and down that his iPhone 4 never did. His N5 loses about 6% an hour with the screen off, meaning he has to have over 40% battery for his phone to last through his sleep (he refuses to charge it while sleeping and says he never had to with the iPhone).
Unfortunately GSam battery monitor does not work in KitKat. Can someone recommend a way to get to the bottom of his battery issues (I have already turned off LTE, Location Tracking, auto-brightness, and using ART instead of Dalvik). ...or is 17hours _standby_ all you can expect from this phone?
The ad says: Standby time up to 300 hours†
†Standby time tests used default settings with LTE on and Wi-Fi connected to a test access point. Wi-Fi internet tests had Airplane Mode on with Wi-Fi connected to a test access point, while loading three popular websites cached on a local server. The Nexus 5 loaded a page, waited 40 seconds, and then loaded a page from the next site.
Did he just get a bad one that needs returning?

get betterbatterystats to monitor his wakelocks, 6% per hr drains is BAD, it should be like at most 1% per hour
maybe has location and all syncs enabled?
mine only loses like 6% the whole night, i have like 97% deep sleep at least when screen is off
Check the battery stats in settings. There is a known issue with Google Play Services and wake locks. A reboot usually solves it temporarily.
I put my N5 into airplane mode before I go to bed. No annoying notifications and less drain (no cellular paging). I have verified several nights that I lose 1% battery over 8 hours in airplane mode.

Auto syncs off. Constant account syncing is what drains the most battery when the screen is off.
These solutions unfortunately do not work:
1) BetterBatteryStats requires root to give any useful info. He does not really want to root, but would if he could do it without erasing everything (not fond of backup/restore either, but if you can FULLY backup without root [or get root without erasing so no backup is necessary] then I could get him to let me root it). Probably off-topic, so I will continue to research no-wipe root solutions (keep seeing it referenced with no links)
2) Turning off sync or going in to air-plane mode will not do. He wants an instant notification for any communication-event 24/7 just like his iPhone4 gave him, and I for one cannot blame him, as my HTC One does for me without killing the battery (and thanks to researching this for him, I now have really long battery [even with all notifications] by using Greenify - but he doesn't since he doesn't have root yet).
Number 1 above (and/or Greenify) is the correct solution, I just need to root it first. Hard to do on someone else's phone though... but I hate that he so hates his first Android Experience on the N5 (largely due to the bad battery, and also do to the fact he is scared to root it or even install a custom launcher).
Anyway, thanks for the help (and PM me if you have something to say that is not battery-life related... I'm not trying to thread-hijack)

Is my Note Pro Lte losing power too quickly?

Hello, two days ago I closed the lid of the cover and put my Note Pro LTE in a bag. I just took out the device and found that there are about 81% left. Is this normal?
Depends on what you're running in the background.
Mine looses about 1% every 24h when in deep sleep. I've got everything turned off, including sync, gps, wifi, mobile data (I'm not using a SIM yet), most of the bloatware including touchwiz.
So, even I closed the cover, apps were still running and the power hunger ones continued to consume power?
Just check the battery stats...
Sent from my SM-P900 using Tapatalk
Power hungry, no; but background processes still run like email checking and other sync services.
Considering you probably have sync set up for an email account and Google play services is likely running as well getting about 0.5% drain per hour seems reasonable to me.

Turning the screen off doesn't disable Sync. With Sync enabled, it keeps actively checking for new emails and the lot. Think of it like going to sleep, and waking up every 5 minutes to check your mailbox.
It temporarily pauses games and videos, but it doesn't quit the app. You have to do that through the recent apps menu.
Is there an app that also put those sleepless apps such as sync to sleep when the lid is closed?
When it comes to battery life the first thing to do is get a handle on what your current drain is.
Monitor your battery stats page, look at the times that the device wakes up and at the rankings of applications to see what's using the most power. Third party applications can help here like Better Battery Stats or GSam Battery Monitor.
From a fresh clean boot with a full battery let the tablet sleep unplugged while on WiFi without ever opening any applications or turning on the display. Let it sit like this for at least a few hours and determine your average hourly % drain. Use this as your baseline and see what applications rank near the top. Repeat this with WiFi turned off and the tablet on LTE. Compare the two and if you see higher drain on LTE take a look at your signal strength. Most likely if LTE signal is weak then drain will increase as the radio tries to compensate.
If you see more than a percentage point of drain in deep sleep while on WiFi then chances are an application is keeping the tablet awake or waking it frequently. Those applications will likely rise to the top in the default battery stats page. If not, the third party applications can assist you in figuring out what's wake-locking the device.
Thanks, I will try the test under wifi. I haven't used LTE yet. I bought the LTE version because it has faster processors and quick charging.
Do the tips mentioned in the article also apply to our Note PRO? Do Airport Mode turns off those apps we talk about?
http://www.phonearena.com/news/How-...one-or-tablet-quickly-and-efficiently_id56242
Since 4.3 Samsung OS has a process called Index (from indexing files) draining a lot of battery juice from its first start till completed process (just for 2 days i think).
I had noticed this since Note 2 update to 4.3, and now with 12.2.
But I can be wrong......or not.

Seems fairly logical when you think about it . . if you're trying to fill a bath tub it will fill much faster if you close the drain at the bottom . .

[Hidden battery drain] 97% Deep Sleep, 7% / h consumption

Hello everyone.
I've been running stock Lollipop on my Nexus 5 for the past week or so. Fully wiped when flashing the factory image.
I've noticed erratic battery consumption since then, but before Chainfire's latest Supersu, most battery apps didn't work well, so it wasn't easy to be sure of what was going on.
Last night I had this impossible battery drain. As you can see from the screenshots, my phone has been up for 7h 48m, in deep sleep for 7h 36m, with the screen on for 5 min, and awake for 11 minutes.
So how it could have consumed 7% battery per hour baffles me.
Has anyone noticed something like this?
Cheers,
TD

Dunno but you have unknown signal 100%. You get this when your wifi is connected, but your wifi was only connected 14%... So what was happening with your signal for the other 86%?

Tasker turns on my wifi at 8:01 am, which would explain why the wifi was on for 1 h and 4 min (9:05 am - 8:01 am).
I assume that No Data Connection is for 7 hours and 46 min out of 7 hours and 48 min because before 8:01 am I had the phone on 2G and Data Off. Then Tasker re-enabled Data and Wifi, and I suppose that before the phone connected to the Wifi, those couple minutes passed by. After those couple minutes, the phone connected to the wifi, thus stopping to use the Data connection once again.
The No or Unknown signal is also a consequence of this. I get that when I'm using a 2G connection with Data OFF.

Noone else has had a similar drain?
Im at about 60% today snce taking my phone off at 7am. Have not done ANYTHING with it though since Im at work. Dont know why this is this low as on KK it would be at around 80.
My battery says its mainly chrome but I havent even been using chrome since I work behind a computer...... odd

Inconsisten battery life on Pixel 2

Dear all,
I have a Pixel 2 and am having some issue with battery life. Some days, it is crazy good: I leave my phone at 100% before going to bed, and I find it at 100% when I wake up in the morning (about 7 h of deep sleep for both me and the phone). Some other days, I lose about 40% over the same period of time. In both situations, I don't touch the phone from when I go to bed until morning. Bluetooth is disabled, WiFi and Mobile are enabled. My WiFi router is always on and I have very good cellular signal.
I thought that a rough app/wakelock could be the culprit but, using BetterBatteryStats, I have not been able to find any. The only unusual "process" seems to be one that is called "No Data Connection" and "No or Unknonw Signal", which show up as 87%, whatever that means.
Does anybody have any ideas as to what could be the source of the problem?
Many thanks!

Losing 40% charge in standby mode is a serious issue. Could be a defective battery. Why don't you return the phone to the store you bought from and get a new one?
Sent from my Pixel 2 using Tapatalk
Maybe you have dodgy mobile coverage where you are? If signal is weak or in/out of service any phone will use a lot more power trying to stay connected to a tower it can find. You may also experience that a phone seems to 'camp on' to a tower with a weak signal (consuming more power) even when it sometimes finds a stronger one from the same location.
No solution, other than to move!
I didn't experience any of this with my, now, old Nexus 5x, so I'd say that mobile coverage is unlikely to be the cause.

Full signal
I should also mention that rebooting the phone solves the "fast discharge" problem

Dear all,
I have a Pixel 2 and am having some issue with battery life. Some days, it is crazy good: I leave my phone at 100% before going to bed, and I find it at 100% when I wake up in the morning (about 7 h of deep sleep for both me and the phone). Some other days, I lose about 40% over the same period of time. In both situations, I don't touch the phone from when I go to bed until morning. Bluetooth is disabled, WiFi and Mobile are enabled. My WiFi router is always on and I have very good cellular signal.
I thought that a rough app/wakelock could be the culprit but, using BetterBatteryStats, I have not been able to find any. The only unusual "process" seems to be one that is called "No Data Connection" and "No or Unknonw Signal", which show up as 87%, whatever that means.
Does anybody have any ideas as to what could be the source of the problem?
Many thanks!

No rogue apps in your battery stats during the 40% drain??

No, none that I can detect.

I also get either 0% or 0.1% overnight drain as well. But what are you looking at in BBS? I usually look at partial wakelocks and alarms. Next time that happens take a look. Once on my Pixel I lost that amount and as it turns out a news app was running a video all night long. I sincerely doubt it's a defective battery but rather a rogue app and that's why a reboot fixes it. Push comes to shove you will have to head over to the BBS forum and post a log file. There are instructions in the OP.
