GPS - Battery killer, or just waiting in idle? - Nexus One Q&A, Help & Troubleshooting

When selected via the Power Control widget, is the GPS ever REALLY on unless you're running an app that actually uses it? In other words, would it be any more battery friendly to leave it disabled and then just enable it before launching an app that needs it (such as Google Maps Navigation)? Or is it safe to just leave it always enabled?

I have it always on and it never shows up under battery-usage-since-unplugged, Probably because nothing is using it.

Thanks for the reply. I guess I'll leave it enabled for awhile and see for myself.

Yup...me too. I have it on all the time and my battery is just the same as not having it on. I actually have everything on the power widget on.

Good to know. I'm going to turn it on and see how it effects my battery.

Well, I'm pretty certain that keeping WiFi and Bluetooth on at all times will drain the battery quite a bit, whether you're connected to other devices or not.

thats different though, as they "search" for something to connect to.
not the case for the GPS.

Right, I'm getting that. But what kind of feedback can someone give on battery life when he/she is already a serious power drainer?

Turn off gps possible?

Hi Guys
i've heard that you can turn off the gps which would imply its permantley on, is this true? If so, any one know how to turn it off as I can't find what is probably an obvious menu/option.
I need to turn it off as i am only getting six hours of idle on any charge of my phone - have an extended batt on order and it is using push email (constantly connected) which is a must for me.
No real complaints apart from battery (which was expected and being sorted) and seems pretty good so far.
Oh, anyone else ditch touchflo? Thought it was rubbish myself
If GPS was able to be turned off, how much battery might it save? The difference could be transforming!
I personally don't think that GPS would be permanently turned on.
Maybe the interface, which "looks" if a demand on GPS data exists...
IF the GPS would be permanently turned on, the battery drain would
be very high, and the device would get assumingly very hot.
mine eats battery more than a fat bird eats bugers and mcdonalds and yes, its very hot as well .. although, this could be coz its pretty much always plugged in.... ?
GPS is only 'on' when it is called for by any external program. If it were on all the time the phone would be flat in about two hours regardless what you did with it.

do you KNOW that or are you assuming that?
I know I have seen programs that turn it off just as usual, the search on here has let me down. If this was definetly the case, then why would programs like these be written?

Yes, it is a known fact that the Diamond heats up when you are charging it (to levels some may find concerning) but HTC have dismissed this as 'normal operation'.
If it was on all the time you would have an instant fix on where you are straight away .
If it was on all the time your battery would last as said around two hours
I think it is in standby mode if this is what you mean but does need software activation to enable it on as in transmit and receive .
Not sure if turning off standby mode would be a good idea but if you google for the chipset name and have a read up it will let you know these kind of things
Are you sure you guys are not getting confused with GPRS, not GPS?
That can drain battery life, and by disabling GPRS Auto Attach using Advance Config tool, can extend your battery by around 40%!

Hi.
I experiencing heavy battery drain Form avast on my non-rooted phone with stock ROM. Like 80% or so..
I am not able to provide a log yet but does anyone got a clue where it might come from?
anyone?
Well avast mostly eats cpu time.. so yeah it will eat battery life.

Yeah ok but on my other phone GT-i9505 it's nothing near 80% like on my this one..
80% seems pretty much considering that the display usually drains most battery, right?

No actually combine network activity with cpu activity and the display can become the lesser evil.
You should look at the wake locks perhaps something you are not noticing.

I am checking the wakelocks now with greenify.
thanks for the info!
How do I combine network activity with cpu activity?
Is there a thread reagarding this?
Note: I am not quite sure whether this works.
I use Tasker to do the following:
Profile>Status>Display off
In-Task>Network>Mobile Data 2G/3G>only 2G
Out-Task>Network>Mobile Data 2G/3G>prefer 3G
But there is no option choosing LTE. (This is for my GT-I9505 which is capable of LTE)
I can only enable or disable LTE via secure settings plugin,
but if I enable LTE via Out-Task won't this interfere with the In-Task?
Or what do you mean by "combine network activity with cpu activity"?
Please help a noob out
I mean when you have the network and cpu working hard it quickly eats the battery.
There are many reasons why a phone would use the battery aggressively and it's sometimes a pure pain to track down what or why.

Tremendous battery drain on WIFI

Hey guys, I am running stock 4.0.3 rooted with supersu and using the latest franco kernel. I am getting massive drains even while using the phone on wifi and keeping it on standby, while connected to wifi. Getting drains about 3.3-4% per hour on standby on wifi. This is absolutely crazy. I tried some older suggestions mentioned here https://forum.xda-developers.com/showpost.php?p=62074306&postcount=118 . But even that doesn't work. Battery drain is normal on mobile data, but when connected to wifi it absolutely goes crazy. Can anyone provide any insight? There are no rogue apps, I have been checking through better battery , wld , accu battery, etc.
You've probably already turned it off, but I'll just point it out in the rare instance, but make sure scanning is off. However, I did notice that you said it is when wifi is on and your phone is sleeping when you get that drain. A fix is to go into wifi settings and under "Keep Wi-fi on during sleep", pick the only plugged in option. Ideally, you should get to the bottom of this issue, but if you don't have the time and no one else figures it out, this may help.
EDIT: I wonder if smart wifi switcher has anything to do with it? Wifi connectivity fluctuates and if you have two connections that have very similar signal strength, would your phone constantly switch between the two networks in a futile manner? If this does happen, I can see that draining your battery significantly, but this is based on the premise that the switcher does not have some type of buffer zone where it does not switch if the difference is negligible.

Yep, I always keep scanning off! And i did try with that suggestion too, I changed the setting to never and it still drained battery. Wifi stayed on for sometime even though i set it to never and then finally turns off after a period of time, but i think that could potentially drain more battery? Are you using wifi all the time? What are your stats?
I have all those settings turned off, smart switcher, ipv6, scanning, etc

Last thing I can think of is trying to use stock kernel to see if it is FK that is the culprit. FK shouldn't be the issue, but perhaps something screwed up during the flashing process? Now I'm essentially just asking you to do trial and error

Note that I'm in Beta 3 and running its stock kernel so I don't really see the usefulness of giving my battery stats, but yes, battery life for me has been good and unaffected by wifi draining.

It's most likely not just you, but based on my perusal of the 3T forums (especially on the FK thread because that's most relevant to how you set up your phone), not many people are facing this issue. Does betterbattery stats not show anything funky or out of the ordinary? Can you post a screenshot of your betterybattery stats including the kernel wakelocks, alarms, and partial wakelocks page?

I'm beginning to think it's not wifi, but the app Saavn. It may act differently when on wifi vs on cellular data and remain active constantly when on wifi. I google searched the app and its potential of being poorly optimized app, and there are reports of it never turning off and running in the background. If that is the case, it should be showing up on BBS as more of a drain, but for some reason it isn't. Still, try uninstalling the app and see what happens.
In the end, if this doesn't solve the issue, I'm beginning to think a factory reset maybe in order. I wish you also gave me BBS alarm wakeups page because that would help see if Saavn is constantly firing off alarms or not.
Go to your "Location settings" and into the 3 dot menu in upper right. Turn everything off.

I don't have any option to turn off wifi calling in there. I am running the beta 7.1.1 now though. But the problem still persists. Too much drain when using wifi, it's being shown as android system drain. I've seen many people reporting it, so it's not just me. But for the life of me, I can't figure out what's causing it!
Issue resolved with latest 4.1.0 and some usage pattern changes. Mod, please close the thread. Thank you!

Worse battery life since the Oreo update

Since the update, I have definitely experienced worse battery life, especially overnight on standby/idle and also overall when I'm at home on WiFi in general, I have read a few posts about the November security patch causing worse battery on a lot of different phones so I don't know if it is because of that, I just hope either the December patch sorts it, or HMD make the battery optimisation better in the next update patch from them soon, has anyone else noticed worse battery performance since Oreo?
Doesn't seem any different to me ill be honest.
For me it even seems to be a little bit better than on Nougat.
I have stellar battery life all together but standby could be better. The other night I lost 3-4% over night and that is more than the usual 1-2% I'm used to on my phones. Not something to get upset about really but something I've noticed.
No battery drain here, my opinion seems the same good as on nougat to

Me too. I have a little better battery performance since Oreo.
Although I'm a battery drain. I only have 18 apps allowed to work in background. I have enabled "Clean background activities" in battery menu too.

Same here, I have most of my apps disabled apart from things that actually need to be running like PingID for work authentication / MS Authenticator / emails and 4 or 5 other things.
Try "data saver" if you have that option in your OREO ROM
Yes I did say DATA saver
Go to Settings - type "data saver" in the search box - switch it on
Works magic for me with a standard OREO ROM and nothing else.
since 8.1 update, battery draining has been worse

Question Why are these sensors active ?

Never had these usage stats in the past like palm sensor or pressure sensor on my previous galaxy devices active . Since I have all those features turned off. Yet according to GSAM they are still running and active. Trying to tame the wakelocks the attached is screen shot of activity when device had been not used for the hours and mins shown.

Strange. Try in safe mode and clear system cache.
Try disabling Google play Services when at rest.
Try clearing the app cache in memory then immediately turn off. See what wants to run latter then when you first go SO with Device Care.
Likely running under Android Service... that worm's nest
What's the battery % usage per hour at rest?
Should be about:
AOD always on >1%@hr
Tap on AOD >.5%@hr
It should be more efficient than my 10+
What app are you using to measure that, get those stats?

Using GSAM. Also the Samsung AOD system is running when it's all off. I think their related to my first post on this matter.
Cool.
It may be misreporting what's active (like that never happens).
If the battery usage is around what I posted before or better when sleeping I wouldn't be concerned.
I'm still thinking about getting a 20U but damn Android 10... Samsung may belly flop again next year. The semiconductor situation isn't looking good either.

I agree with everything you wrote. I'm a dense nerd here, and so I recall either Samsung or a computer graphics card company making a post somewhere recently describing how many of these apps often give misreadings.... But yeah, since I'm a nerd I often lookup too many tech things and then can't seem to remember which was which, haha.
But on the bright side, I'm thinking about trading in my S21U for a P6P in a few months. I'm definitely sick of dealing with all of the problems that always seem to come with any Samsung product (or perhaps I just have bad luck and always get their crummy products lol).

Yep I agree. We'll see. In the past I'd get 0.4 - 0.5 percent an hour drain sometimes less. This is higher. Around 0.7 to 0.9. Screen time usage is about the same however.

Of course I do and I never use airplane mode or power saving modes. Accubattery is showing better values than GSAM though.
This is my overall consumption after 40% usage.
Starting to make and see some improvements.
Meh these so don't need to run. Google play Services occasionally does, but those media apps are security risks... just saying.
