Running AOSP ish rom and applied the latest GPS fix (can't remember exactly which one).
So I have been running this rom for a long time, like since it was released. The only issue was the gps was still crappy. I did the hardware fix but that didn't help. About 2 months ago I saw a new fix which involved changing the info in the gps settings page. Anyway, gps is fast to lock (like 5 seconds) and is accurate now.
Around the same time I did the gps fix, I noticed I started having worse battery life. I hardly use my phone during the day and some days don't make a call or use gps, internet (other auto email notifications) etc but I notice my battery is down to 10-20% at the end of the day, approx 10 hours after taking it off charge. This is while at work with no wifi connected and no way the gps could get a lock.
Now if I am off, going from place to place in my car (connected to my bluetooth head unit) and when at home the phone sitting on a table, connected to wifi and with a reasonable ability to get a gps lock, my battery is still 80-90% charged at the end of the day.
What could be causing this? I have thought that when at work I have a worse signal and that the momentary loss of signal and the searching for a signal may cause this. How about the fact that it isn't connected to wifi but there are a couple available?
Thanks for any info.

I would like to know if anyone has any experience with the quality of the gps reception inside a bakcpack.
I would like to log a trail for about 3 hours. And keeping the HD2 in hand for 3 hours could be a bad idea. I would like to place the HD2 inside a backpack of course as closest to the outside as possible. Is there any chance of still getting any acceptable gps reception to log my trail?
I tried that in a small test. I placed the phone in the pocket of my jeans and logged a small distance. But the trail was a little bit misplaced. Drawed over the google maps map my track was not exactly on the street I walked.
Anyone tried that?
If I can get a lock in my house (bottom floor) then there's a good chance in your back pack, only one way to find out for sure, have a quick walk round your block with your back pack on....
I'd be more worried that the battery will lasts 3 hours..
battery should be no problem, I have an external battery pack (Just Mobile Gum Plus). I just want to make sure that this measurement will work. I have only one try. So I need some tips/hints to maximize the gps reception...
does no one have any experiences in loging trails with this phone?
Should work ok! (Use it in my pocket)
However, you say you have an external battery. This means the device is always getting charged, which could increase the temperature of the battery. So, if you want to keep the device running, you should ensure this heat is removed from it (so, don't put it in your sleeping bag...)
I have used HD2 on long hiking trips and have logged my trails with no problems. Your GPS will get great reception in the outdoors, much better than in cities. A backpack will not affect the GPS signal at all unless you've got it lined with metal!
Well just tried the backpack thing while going to the supermarket. But the result was quite unsatisfying. The gps signal got lost. THe second try was my jeans pocket. Worked neither.
Where did you exactely put your phone in the backpack and in what direction was it faced?
Ok thanks for all the answers. I found the solution for my problem.
I used Navicomputer in combination with S2U2. As soon as I hit the power button of my HD2 (forced standby) the GPS reception was lost. Even with the option ind NaviComputer set prevent standby.
But if I just let the phone switch to standby (leave it unattended) it worked.
Can someone explain that to me?
GPS reception in the backpack was good enough...measurement over 2h worked.
The battery lasted more than 3h of gps tracking without any external power.
Glad to hear you got it working. The GPS probably turns off automatically in standby to save power in the same way that your WiFi connection will automatically disconnect if you leave the phone in standby for long enough. Hope you had a good hike!
I work in an office which is a level below ground in central Sydney so most of my work day I am out of reception.
Now I do venture into reception areas so every now and then so don't want to turn aeroplane mode on and off all the time.... So please don't suggest this.
With my previous phone (i8000) I didn't have such a drain on battery when out of reception all day from what I remember. I used to get really long standby times but I didn't use the screen anywhere near as much.
Now I know the phone will use more power in low reception areas because it needs to turn the sensitivity up to get clear signal. But the i9100 seems to drain much more than all my other phones I have used.
I am on stock I3 firmware with CT Root kernel. I have a high level of 44% Cell Standby with only being on for 6 hours (and out of reception for 3 of them) even though I have used the screen for 1 hour and that only shows 37% of usage. I don't remember it being this bad on H3 but to be honest I didn't really check for comparison of usage.
Is this normal? My old O2 phone on win mo used to go into a state of sleep for searching for reception when at work because it used to take a few minutes sometimes, after I got into reception zone, to realise I had reception. The i9100 seems to get it straight away which makes me think is it polling all the time I am at work and draining the battery more because it tries so hard?
Hope I made this clear.
So it appears like from research this high drain is fairly common on android devices when in no reception areas. I could understand why it would happen in low reception areas where the phone uses more power to pick up a weak signal. But why would the phone continually do this in a NO recpetion area. I thought samsung would have made the phone relaise it has no reception and only try every 5 minutes or so...
I never noticed this on my i8000 or any of my win mo phones before it. I assume they realsied there was no reception and stopped polling at full strength the whole time I was at work. This would have been indicated by the slight delay of leaving my bilding before getting messages sometimes where now its instant. But without the battery usage stats I can't compare.
I have tried to find an app that automatically puts the phone into aeroplane mode when NO signal for 30 minutes or something. And keep s turning aeroplane off every 5 or 10 minutes or so. But I have yet to find anything.
I realise there are programs that will use GPS and do it automatically but this is not ideal. I only want it to happen when I have no reception.
Any ideas of ways to fix this without me manually putting my phone into aeroplane mode when I'm in my office and remembering to take it back out when I know I should have reception? I don't want to use location based because this doesn't work when I go up one level.
Just bumping my ancient thread.
After an app that will recognised NO reception for long periods and automatically put flights mode on. Then turn flight mode off briefly every 5 minutes or so to check if reception is back.
In my office I have no reception but if I go up two levels I do. So time based automation does not suit nor does location based unless it knows what level I am on.
See above for the long story

I have been meaning to post in here about how great my battery life has been, especially after seeing all of the threads complaining about it. I have been going home after a 9 hour day with 70-80% and even with extreme use, I have had no issues.
That being said, today my battery drained inexplicably fast for no reason. I checked my background apps and closed a few, but the battery drain persisted, so I rebooted.
Anyone else having this issue or know what causes it? This is the first incident I have had in almost a week. The last app I launched before this happened was Inrix traffic. Battery life has been beautiful, otherwise.

That's the fix I use. I now call my 920's battery life non-deterministic. It's great, except when it's not. When it's not, even if it looks like it should be because nothing is running, a reboot fixes it. Until the next time.
I would be shocked if there weren't an OS update to fix whatever process is going rouge and running away with the battery. Because it's something in the OS. Or at least its something the user cannot remedy, short of taking off and nuking the site from space.
I've noticed this a lot too. I killed a whole load of background apps and the battery life got a lot better. Then it got much worse again.
I believe my main problem is that I live in a low signal area. So I drain the whole thing in about 10-11 hours, even when out working the majority of the day.
One thing I have found is that the radios in the handset are very badly shielded compared to my previous handsets. This does mean that I can hear when the phone is sending out signals/utilising the radios. It does this a lot, even when it does have signal. It must consume a massive amount of power.
I get roughly 5-6 hours or so. Charger I bought on Amazon no longer does the trick (it's one that plugs into the cigerette lighter in your car and two USB outs). I have to bring with me the power cord and an inverter to keep it charged up so it makes it through the day.
I've got NFC and Bluetooth turned off, Wi-Fi on and the phone set to 3G mode. I get pretty solid battery life out of it.
When I feel the back of the phone getting warm, I reboot and it's good for awhile. I too would be surprised if there isn't an OS update to fix this issue.

I am heaving same issue with battery. Phone worked fine first 10 days and it started to be warm on the top back. Life of the battery can not last a day and i am a heavy user.
As somebody mentioned in comment to turn off this and that- i don't think so. I did not buy phone to keep everything off on it.
If in airplane mode. had couple pictures and few other things, this is what you get out of your battery.

Excellent. I'll just keep my phone in Airplane mode all the time! What was I thinking, leaving the cell radio on?
I've just had 2 great days life out of mine. Off charge at 6am and currently sat at 58% at 4pm. I've been streaming a podcast from the internet via bluetooth for 90 minutes and I've been tethering too, as well as all the usual stuff, so it's not like it's been sat idle all day. I've even been using Nokia Drive to get to work this morning (I teach at many different schools) whilst streaming media off the web and bluetoothing it to the stereo and it's not hit it bad. Seems very power conservative where internet streaming and GPS is concerned.
I have battery level for WP8 installed and it has a graph so you can see when the battery level is dropping off. I've noticed solid battery drain from running the Audible app which continues after the app is closed. Rebooting solves this. I have been working in an area with excellent signal recently though, that may have made a big difference. I get 9-10mbps on HSPA at the moment. I do, of course, have NFC turned off.
Hopefully Portico will be here soon and solve some of these power problems.
Because Im seriously curious... This phone has a rap of being "atrocious" in terms of battery life... Now I'm not making this post to be mean or anything, In fact I really do want to know what IS causing it or some theories.. and share one theory I have
But my personal experience really says otherwise, Tonight I set a new "record" on my One X+, 16 hours 28 minutes with 2 hours 43 minutes screen on time... And I didnt do anything "extreme" to achieve it, My Google Now is on, my location services are on, autosync is enabled.. About the only thing I have done is install JuiceDefender (My previous record without Juice Defender was about 15-something hours) I watched youtube videos, Read some websites, listened to music, and even played some games... I'm completely stock, no roms or anything
Now, I will note, I had a problem the other day where my battery killed itself, FAST.. After a bit of digging around and tweaking, I discovered the cause was that my One X+ wasnt entering Deep Sleep, and thus the processor was staying at 475mhz or so even when the screen was locked (Causing the battery to be drained like i was using it) What caused this? My Wi-Fi, of all things, While I had a really good signal, I had it prioritizing the 5.8ghz radio, and in my room, the 5.8ghz signal is fairly weak as im a ways from my router... so the phone was switching between it and the 2.4ghz signal, causing the phone to be unable to sleep, Removing the 5.8ghz AP from my phone fixed the issue completely and my phone returned to "normal" behavior...
Yeah i know it sounds really farfetched and weird, and took me a bit of googling to get the idea that this might be what was causing my issue (I tested my hypothesis by turning Wi-Fi off completely and using Cell data, Sure enough my phone slept like a baby and barely used any battery.. i flipped Wi-Fi on and suddenly the phone was drinking its battery down rapidly.. I disabled the 5.8ghz AP and suddenly the phone worked 100% properly again)
I suspect that this is the cause behind some folks who are saying their phone is draining down 7% in 20 minutes with it locked, Its simply not entering deep sleep, the processor is doing something in the background... Could some of them be having the problem i just described? Its possible, Especially if you have multiple Wi-Fi points in your house.. Could the wi-fi in the One X+ be bugged? I dunno, Thats possible to, Thats why I'm posting this...
Now of course some people need a phone that is going to go for 2-3 days without a charge, and no, this isnt the phone for you (There arent many smartphones out there that can manage that if you actually USE it any) But really.. 16 hours with 3 hours of screen on time is pretty darn good.. Thats getting quite close to my Galaxy Nexus with a 3500mah Extended Battery (Around 18h standby, 3.5-4 hours screen on) despite all of the "handicaps" the One X+ has over the simple GNex (Like LTE and a Quad Core processor) and is vastly better than my stock Galaxy Nexus battery which died constantly...
And yes, heres a screenshot as proof if you dont believe me...
I just want to add that I find that googlenow also drains the battery and as such I always disable it. It was a problem on my S2 and thus I have disabled it on my HOX+
Honestly, mine wasn't lasting longer than 8 hours until I rooted it and simply "froze" all of the AT&T apps I wasn't using. That alone gave me an extra 2-3 hours a day of battery life! (I've read here that the AT&T apps, even if you aren't using them, keep running in the background) The other thing that seems to help is an app called Smart WiFi toggler that's done wonders for both myself and everyone else I know who uses it in terms of minimizing WiFi battery usage.

I'm sure other folks have other tips, but this has been the winning combo for me.
I should add that i also froze every ATT app i could and never opened ANY of them.. So maybe thats part of it as well..
JuiceDefender i believe is doing something similar for me with the Wi-Fi by turning it off when its not needed...
My battery life was terrible when I first got this phone. I let it charge out completely once this month and I've been using LBE Security Master. Those two things have greatly extended my battery so much I have been able to go more than a day with it before charging. Another factor might be that my phone isn't carrier branded or anything.
The "My Wi-Fi isnt letting my phone enter deep sleep" thing is actually starting to get annoying, I thought i fixed it but it keeps coming back...and yes, it is legitimately killing my battery at twice the normal rate because the phone will -not- enter deep sleep
My phone goes into deep sleep just fine if i turn Wi-Fi off...and my battery drain returns to normal....So it cant be some app downloading stuff or constantly pinging the internet or else it would do the same thing when im on LTE...
Also i've reset the "Keep Wi-Fi on during sleep" option to never 20 times now, it keeps going back to "always" on me...
Ideas?
My battery life is ok. See here:
http://forum.xda-developers.com/showthread.php?t=2067143
Mine is too, Provided i turn Wi-Fi off or i get the bug to go away for a bit (basically toggling wi-fi on and off a few times and twiddling with the settings makes it work right, but the problem comes back minutes or hours later)
Otherwise, Wi-Fi wont let my phone enter deep sleep, and my battery drains like im using it..
The thing thats annoying me more is that the "Keep Wi-Fi on during sleep" setting will not stay where i set it and keeps going back to the default setting....
I guess i can just toggle wi-fi on and off manually...
Hello everyone.
Recently I acquired a Cube U9GTV tablet. When it comes to value for money, it's quite okay. However, I think that something drains its battery.
This is my first tablet so obviously I have no idea what to expect, but I have a Samsung I9000 running 4.2.2 and compared to it, tablet's battery is out of the league. My phone can stay up to 3 days being idle, taking no more than 1% per hour (of course without wifi/3g/gps, just cell signal). When it comes to my tablet, it can hardly last a day without charging, eating 2-4% of battery per hour. No wifi, no synchronization, no location access.
Maybe I just expect too much, but I some other users of this device report that their device can stay alive up to 3 days, while being completely idle. Mine cannot make it to a day.
Things I have done so far:
Clean ROM install, no Google account, no Synchronization, no Wifi, no BT
Deleted Phone.apk, TelephonyProvider.apk, MMS.apk -> the Mobile network signal bar in Battery status changed from red to yellow, battery drain decreased a bit
Disabled Media Scanning by Rescan Media Root
Stopped Google services running in the background (but didn't touch the cached ones)
My tablet enters Deep Sleep with no issues. But I noticed that the battery drop rate is not a constant, it varies and it seems that sometimes it drains the 1% per hour, but then something happens and hops to 4%/h.
The thing that concerns me is the Mobile network signal, which is completely useless cause my tablet is only a Wifi version, and I do not use external 3G modems.
I am unable to see battery usage in Settings, it just says it's unavailable. So I got myself Better Battery Stats, made a test and screenshotted results (see Attachments).
Why does it show No or Unknown Signal and No data connection at 100%?
If you have any suggestions or tips, share them with me please.
Thank you in advance.
Bumpety bump.
