Battery - Wi-Fi and Awake always solid blue

So I've been trying to get more life out of my battery, I get decent now, but not the 18+ hours I've seen other people getting. I think the main problem here is, if I go view the Applications -> Battery Usage screen, the "Wi-Fi" and "Awake" bars are always full blue, even when the phone hasn't been touched in a couple hours.
Does anyone know what actually causes these to now sleep? Is it push email? Or some other setting I'm missing?
Thanks

Try Menu/Settings/Wireless and Network/Wi-Fi Settings. Then press Menu/Advanced/Wi-Fi- sleep policy.
Play with those settings. You are probably set to "Never". Folks have actually been reporting better battery life with this setting (powering on and shutting down the wifi eats up battery) You can play around with it to get your own results.
Hit thanks if this helps!

Ah...yes, it is set to never. So leaving it on "never" gets better results, say if you're at home and always have a wifi connection? Also, if the wi-fi is on, does that mean the device can't sleep I take it, that's what's keeping the device awake with screen off?
Thanks for the tip.

I've heard both sides to this argument, and frankly I don't think most people understand why changing it does, or in other cases does not help.
I suspect that the answer to your issue isn't going to be found here. Here's the theory:
- Setting wifi policy to "Sleep - Never" results in better battery life for some; it's likely because these individuals have a fairly low 3g signal, which tends to draw more battery when periodic updates/synchronization occurs (e.g., gmail, calendar, facebook, etc.). By leaving wifi Sleep set to never, the wifi (which THEORETICALLY uses less power than 3g) can do the work instead.
- Setting wifi policy to "Sleep - When Screen is Off" can result in better battery life for a number of reasons, many of the underlying issues being hard to identify. For example, if your router tends to send a lot of 'noise' and wake up your phone, having wi-fi disabled will prevent this. Location services in the OS - which you've probably permitted to 'help locate you faster' - even when you are NOT connected to a wifi network - will periodically ping wireless networks around you to help facilitate faster geolocation. This uses battery as well.
But don't confuse the generalities that have spawned from people's anecdotal situations with what could be a very different problem.
Was your phone primarily located in one location during most of the 'awake' period? If so, then it was probably connected to the same router most of that time. If so, it really shouldn't matter what the setting was for Advanced Wifi - the phone should still sleep.
If you turn off wi-fi on the device, and the device then sleeps, then you've narrowed the issue some, but that is not a solution, because what are you going to do, not use wifi?
You've got to dig deeper; your issue may be any of the following - rogue app that keeps a wakelock, rogue app that updates too frequently, wifi modem issue, router issue, OS issue, etc.
In short, you need to figure out what's keeping the phone awake. Get CPU Spy and Better Battery Stats to help you get insight into what's keeping the device awake.

Thank you for that very informative post. My phone was on my desk all day today( worked from home ) and wi-fi is set to always on, and it never slept, not even once.
I'll try disabling wi-fi( should have done this earlier to be honest and checked ) and then I'll download those apps, I just got Badass Battery Monitor, I'll check out the two you recommended as well. Thanks for the info!

Your phone should still go into deep sleep with wifi on. If it doesn't then you have something else wakelocking your phone. However, if wifi is set to never sleep, and wifi is enabled, the bar on the battery chart will always be solid blue.

So just installed CPU Spy, it looks like IM+ is the biggest user of wakelocks. I like to always be signed in to my accounts, but not at such a huge cost of battery, does anyone know of a better multi IM client that will push updates to you? I used to have IM+ on the iPhone( yea I know, just switched two months ago, and never looking back ) and the push on it worked great. The 'push' IM+ says it has is awful, most of the time I never get my IMs sent to me at all.
Also have skype signed on all the time, not sure if that is wakelock'ing anything, I'll have to keep an eye on it, it didn't show up on CPU Spy.

Try IMO, free from the Android Market. Its a multi-IM client that combines most common clients including Skype. I've used it. It creates some wakelocks, but not sufficient to wake the phone. I don't use IM very often so I'd be curious to hear how it works for you.

So been trying IMO the past couple days. Seems much better than IM+. Haven't seen any disconnects, I get my IMs about 30sec - 1min after the computer gets them, which is fine, and the wake-locking is extremely minimal. IM+ was awful with the wake-locking.
So that clears up the Always awake issue, flashed Blazer 3.8 last night, so can't comment on battery too much yet, also calibrating today.

Galaxy Nexus BTLowPower keeps running when bluetooth is off

Hello,
I’m looking for help with a rather strange problem. I’m getting a lot of awake time in Android OS. I installed BetterBatteryStats and noticed it was the service BTLowPower that was doing a lot of kernel wakelocks.
I turned bluetooth off a couple of days (and have rebooted in the meantime even) but still the top service in kernel wakelocks is BTLowPower by a very large margin ... how can this be if bluetooth is turned off ?
Stats are in BetterBatteryStats Kernel Wakelocks
Unplugged 12h47min.
BTLowPower 9h33min, 74.7%
I've attached a screenshot
I have a Galaxy Nexus which is running stock Jellybean.
Thanks in advance for any advice !

Same here.
Please help.

Do you guys have other Bluetooth devices around? I have a Motorola S805 headset as well as a cheapo BT2.0 dongle from DealExtreme.
I typically don't have the headset turned on unless it's connected to the computer, but what I'm finding is that if I just leave my phone with the dongle turned off and the headset turned off then I don't get the BTLowPower battery drain.
If I turn the dongle on, and turn on the headset then I typically get the BTLowPower battery drain in my GNex. I have to reboot the phone for it to go away. I'm not really sure the exact sequence of events to cause the drain to occur, but I feel like it's definitely related to turning on and off my S805 headset or being around the dongle.

There might be other bluetooth devices around (such as phones of a colleague or something), however the bluetooth on my phone is turned OFF and I still keep getting the BTLowPower in kernel wakelocks Today for example it kept my phone awake for over 10 hours

Anyone ? I keep having this problem ...

Same problem here. BTLowPower keeps draining my battery.
I have bluetooth and Jabra headset off...
It usually happends when I unplug my GNex from charging.
Please help....

sorry for my bad english.

Same issue
I'm running a Toro Gnex with the Vanir AOSP ROM. It's buttery smooth, and I've had no problems at all, other than this specific kernel wakelock. Same scenario as the OP.
If anyone finds out more about it, I would be grateful!

I've been reading about this all morning. I run Automateit Pro and have it go into airplane mode at night. After losing 25% battery overnight, the investigation began. BTlowpower was keeping the phone awake. It looks like airplane mode can be the culprit, possibly in combination with Wifi set to always on. I am set up to turn Bluetooth off a couple of minutes after going into airplane model tonight, I'll follow up with my findings over the weekend.

Great, keep us posted. I also turn airplane mode on at night, but my Bluetooth is always off.
Did anyone try to hard reset their phone ? I called Samsung but I got the standard reply to hard reset my phone, I haven't tried it yet because I doubt it would work and I have a lot of authenticators on it and it's a bit of a hassle. But if any of you guys already tried it I would love to hear if it worked ! Thanks !

BTlowpower issue solved by turning Bluetooth on and then off again after Airplane mode activated. However, that caused another issue - modem_usb_gpio_wake to crush my battery. Doing more testing today to resolve that one - will post again when that one is solved.

After testing different configurations this weekend, it looks like turning off sync causes these 2 kernel wakelocks. I tested 2 states: Airplane mode + no Wi-fi, and no data (no Wi-fi + no Wireless data, voice signal on). In either instance, the wakelock occurs with sync off. Leaving sync on finally achieved the low overnight battery drain (< 5%) I've been looking for. Regardless, to avoid battery drain after shutting data off:
Turn Bluetooth On and then Off again. If you are using airplane mode (this may be overkill), also turn Wireless Data On and then Off again.
Let me know if this helps.

Hi thanks for posting !
Just to make sure I understand, you say the solution is to turn bluetooth on and off again after turning off airplane mode ?
Just for completeness sake, this is my situation: overnight I turn on airplane mode and I sometimes have the wakelock draining my battery during the day (but not always). Draining doesn't occur during the night as while it's on airplane mode I'm also charging it.
I will try every morning when I turn airplane mode off to turn bluetooth on and off again afterwards for a few days and see if that helps. Let me know if I misunderstood.
Thanks,
Jorn

Just found a kind of workaround at another thread, this might be helpful (if it works ).
It doesn't, the drain still occurs >_<

I actually have a workaround that works for me. During the night I turn off my phone instead of using airplane mode. I no longer have BTLowPower and I also am able to successfully connect every time very quickly with bluetooth to my carkit, which previously was very flaky. It's definitely a standard issue though with the galaxy nexus, I can reproduce it on 2 other galaxy nexi as well.

I just installed BetterBatteryStats two days ago, and I'm seeing the exact same results. I can't help but wonder if the issue is at all related to the kernel I'm using (LeanKernel v4.7), or if perhaps a resolution to the problem could be solved by a modification within the kernel code. The ROM I'm running is BAMF Paradigm v2.4, which is based on AOSP v4.1.2. Like the rest of you, I'd really like to get this fixed.

After three days or so, the issue seemed to go away on its own. I didn't make any changes to any of the apps I was running, nor did I update the kernel. I really have no clue what took care of it for me, but I haven't seen it since.

Weird, mine went away as well after toggling BT a couple times. Guess we'll file this one under unsolved mysteries

Wifi on leads to excessive heat.

Recently upgraded and re-rooted and seemly after an update to G3 tweak box keeping the wifi on destroys my battery and heats the device off.
Better battery stats states that the sensors.qcom have been going forever.
Work around for now is to use the device without the wifi on. Thankfully I have unlimited data, but this is kinda annoying.
Any help would be much appreciated.

In my case, once I turn on Wi-Fi, not only the top back part of the device starts heating up, also the phone becomes laggy and buggy. For instance, clicking Quiet mode icon doesn't actually turn it on/off. Additionally, my text messages stop sending/receiving for some time (up to hours!). What I've noticed is that my LTE icon with arrows lighting up appears for a few seconds, then goes away, then reappears, and the cycle continues. I can confirm that my WiFi internet works though, since if I disable mobile data, I am still able to access the internet.
Playing with advanced WiFi options, and removing all saved networks did not help. Having WiFi on, but not connected to any network, is fine and doesn't cause any of the above.
I kept the WiFi off during the weekend (good 2-3 days), and everything was cool and smooth! But I can't just not use WiFi; it's not efficient and I used ~1.5GB of data.
A friend of mine said their colleague experienced the same. He did a factory reset and everything is good. I have not yet had the time to try that myself.

What is your signal strength on Wifi? Mine does seem to heat up considerably on Less than optimal signal strengths.
Mine has been recently returned to stock and wiped, in advance of me RMAing it because I have the "cracks" developing at mic and infrared ports.

Signal strength was almost full. It still heats up with a lot of use, which is understandable. Definitely not as excessively as before (when I wasn't doing anything and it was heating up).
I didn't play with any of the advanced Wi-Fi settings (did not change them from the default), except for removing the checkmark of notifications of open networks.
No signs of cracks on mine, and I am not using a case currently (it is being shipped to me).

Just an update:
No issues with WiFi yet. Some heat during heavy use, but nothing like before (in terms of heat and lag).
LTE symbol sometimes appears even when on WiFi, but definitely not as much as it used to. I think it started doing that once I installed Rogers' VVM Plus app (seems like it needs to communicate with the server directly or something). No biggie, since I don't notice any of the problems I used to have.
Lastly, I'm quite pleased with the battery life now!!

I don't think Doze mode is working on my phone...

Hi there,
Please look at the attached screenshot. The red area shows the time I was sleeping. The phone was stationery all night long. It shouldn't decrease like that, right? It should show something more horizontal if Doze is actually working, right? I believe I read something about this somewhere on these forums.
Yes, I do have "WiFi: Always On" enabled. Is that the problem?
My thinking is that I want WiFi always turned on, but I also want Doze. Meaning, if the phone is stationery, not doing anything, it should kick Doze in (which will periodically check for stuff, temporarily turning on/off the WiFi). Is this thinking wrong? If I have "WiFi: Always On" disabled, will Doze work properly and I'll still be notified of any push notifications and whatnot?
What am I missing here?

First off, there are no screenshots. Doze mode is supposed to remove wifi scans and wifi connection regardless if wifi is on. You will get a periodically sync with emails and push notifications( they will be delayed). You will also still recieve sms and mms. How steong is the network connection? Maybe with a weak connection that is what is draining battery.

Not yet, I'll have to try that... However, it doesn't make much sense to me to have it off. I mean, if it's off, even in the doze open windows, wifi will be off, and I won't get any notifications at all unless I turn the screen on. Not a very good user experience. But I'll test it nonetheless to narrow down possible issues.

Based on your post these seem are most likely the same issue. I just flashed the fix from that thread and it helped TONS. It is still being tweaked before it goes to elementalx officially, but it is working great for me so far!

Yeah, it might be that issue, or not, I'm not really sure. But I used the GSam Battery Monitor app suggested above and I don't think the problem is Doze.
I used that app and start monitoring just before I went to sleep. I've also used ForceDoze just to be sure Doze kicks in (this app will force Doze immediately on screen off instead of just stationery and waiting 30mins). Look at the screenshots. Something is not right, my phone doesn't deep sleep, it's awake all the time.

What? Doze is supposed to remove wifi Scans?
If you take a look at the blue "WiFi Scan" line you see the same pause between intervals before doze kicks in as while doze is active.
Doze Mode hasn't really helped me getting less Wakelocks or less battery drain on this device. I just get the feeling there are way to many system/kernel related wakelocks due to HTC's crappy software which ignore doze mode
Oh yeah, the Wifi signal strength was really bad there.... simply because the phone decided NOT to switch to the stronger Network with the same SSID.... well thank you android....

I've used Greenify (which has a notification for Doze mode statistics) and other battery stats apps and I've realized that Doze is in fact working... So, my battery problems are something else.
I just don't get that flat battery graph when doze mode is active, but it must be due to something else...
Thanks everyone that pitched in Save​

I just don't get that flat battery graph when doze mode is active, but it must be due to something else...
Thanks everyone that pitched in Save​

To me it look as though a rouge app could be the culprit.
Have you tried a removing all apps, or doing a clean flash of whatever ROM your on, and if not rooted, an RUU flash and then see if the phone works as should, then this sucks, but you install apps 1 but 1 until you find out which on is the bad apple.
Your phone is def being held awake though by that Gsam battery chart.

I haven't done that and I'm not going to. I don't have time for debugging this issue like that, I need a working phone with the apps I use.
Not trying to sound rude or anything, I know you're just trying to help and I appreciate that. But I just can't do what you're suggesting.
Anyway, shouldn't some battery app help with that. I'm now using BetterBatteryStats. If there's a rogue app, that should allow me to pinpoint the sucker...

HTC 10 WiFi issues

So I have an HTC 10 and I generally like this device but I have a few problems though. Wondering if anyone can help me out.
1. I have extremely high battery drain while using WiFi. Like 1% every minute or two. If I go to sleep leaving the WiFi turned on I may lose 10 to 15% battery life which feels like quite a lot.
2. The battery history graph always displays WiFi as turned on no matter if I turned it on or off. It's basically a solid green line. Does anyone else have this problem or know of any solutions?
Thanks for helping!

There's a few threads about Wi-Fi issues. I have bad drain as well along with many others.
Here is a main one:

Check if Wi-Fi scanning is turned on in Wi-Fi setting and turn that off. It keeps Wi-Fi active even when Wi-Fi is off.

Thanks a lot for helping. I cannot find the WiFi scanning setting though. I checked in Settings > WiFi > Advanced WiFi. Nothing there.
