Hi all, searched and couldn't find what I was exactly looking for.
when i first got the phone, the battery life was short but since a couple of weeks ago, it's gotten much, much worse. i've had the phone for maybe a month or so.
i'm talking about the battery draining 10% in 30-40 minutes on standby with nothing like bluetooth or wifi on. at least the phone used to hold a charge decently if it was on standby, now it drains like i'm using it even on standby.
what are the greatest factors that affect battery life? when i first got the rom i have now, it wasn't this bad so i don't think it's the rom itself. plus i absolutely hate changing roms (it takes hours to get all my settings back)
some things i thought of:
i could use g-light but i noticed this makes my memory use quite higher and this doesn't do anything for when it's on standby anyway.
how often the accelerometer checks for rotation, right now it was at every 200 millisecond. I've changed it to 750 now, i'll see what effect this has.
same thing for light sensor. right now it's at 500 ms now.
radio. but again it was fine at first with this 1.09.25.23 radio.
anything else?
With my original 900 mAh battery the consumption was about 15% every hour. This was with the data connection always on. Without this on, it would last 2 days at least.
I also loose quite a bit of power when I'm in a bad phone reception area.
But not knowing where the battery consumption is being used up can be very annoying.
Whenever I'm abroad (and thus have all data connections disabled with NODATA) I always get a massive boost to battery life so it could be some process sending/receiving loads of data that you're unaware of? To test that you could install NODATA and kill all the data connections temporarily to see if that helps? Not that that would narrow down what was happening completely but it might help point you in the right direction.
i also suspect it might have something to do with data. what i've noticed is that my emails don't download fully, only the titles download and i think it stays connected while it's 'stuck' trying to download the rest of the messages, i notice this because it says in the menu 'stop send/receive' meaning it's still trying to send/receive. normally, i have it set to check every half hour. but i guess now it's always connected to data... anyone know why it's doing this? (maybe i need to start a new thread as i can't find an answer for this email send/receive problem by searching...)
kill the 3G chip that works for me but be sure the the provider has a GSM network
yup, 3g is turned off. these days the usage is more like 5% used up every hour in standby with email checked every 30 minutes. i guess that's acceptable...
Anyone notice a change in their battery life in the past few days? My girlfriend and I both are going through our batteries in just over half a day with no use. It's like the phone isn't sleeping. Looking at battery use Display is using all of the battery. I'm running CM7.0.3 and she's on stock. Looking at mine right now the phone has been on battery for 1 hour 34 minutes, and Display is taking 57% of the battery and I'm down to 84% battery.
Yes! I've had my N1 since January 2010. I stayed stock until recently when I installed CM 7.1 RC1 shortly after it was released. Battery life had always been great, both stock and under CM7, especially with SS4N1. Then, a few days ago it just fell off a cliff. I now get only about 7-8 hours, even with little to no usage. Before I'd barely lose anything if the phone wasn't being used (a percent every couple hours).
Now the Nexus One Battery Calibrator application shows a drain of ~200 mA or more constantly.
I've been tearing my hair out for the last few days, uninstalling apps right and left, trying in vain to figure out what's causing this. I even considered a full wipe and reinstall of CM 7, thinking that some system setting somewhere had gotten horked.
I've always had WiFi set to never sleep, since I'm usually either at work or home. I've also had preferred network type (*#*#4636#*#* -> Phone Info) set to "GSM auto (PRL)" for months.
I've not made any other changes I can think of that would've had such a drastic impact on power consumption. I didn't track all the app updates that happened around the time it started, so I suppose it could be one of those. But I've uninstalled just about everything and it's still happening.
I have the same issue! Just in the past week or so. I have about 50% battery then a hour or so later it's dead! I was going to get a new battery today but maybe it's a CM7 issue. I use the nightly as soon as they hit the mirror.
An update on this... There may be a big issue going on with T-Mobile or some recent update:
http://www.tmonews.com/2011/07/t-mobile-g2-users-suddenly-suffering-from-huge-battery-loss/
Looks like other users on different phones have the same issue!
Thanks for that article, Lost Dog. Makes me feel a bit better. At least I know I'm not just going nuts.
My phone still has increased battery drain even if I put it in airplane mode though. It helps, but it's still much faster than before. This makes me really puzzled as to what the cause could be. How could the cell network still be causing increased drain if the phone's completely disconnected from it? Some sort of configuration information it received that persists even after the cell radio is turned off? EDIT: I may be wrong on this one, see below.
Last night I tried a complete wipe (using Temasek's full format "Format-signed.zip" first), and re-installed CM7.1 RC1 completely fresh. I installed only the minimal Google applications and a couple crucial tools (my password safe app). However, I'm still getting the same quick battery drain today.
I hope we (or T-Moblie) can figure out how to fix this. It really cripples my phone as a useful tool to have such short life!
EDIT: I'm going to try a workaround I've seen mentioned in comments on the TMoNews and Phandroid articles about this: limiting the cellular connection to 2G/EDGE only. It seems to have made a significant difference so far. I may have been incorrect then about airplane mode not having an impact. I'd only been checking current drain with the N1 Battery Calibrator app, and never left it in airplane mode for long. Anyway, I'll post back later this afternoon with results.
Ok, so switching to 2G-only for the cellular connection seems to have made a HUGE difference. The drain rate seems to be back at around what I'd expect. Everything else I left exactly the same (WiFi on, GPS enabled, same applications, etc.)
So, I'm starting to suspect something may be up with T-Mobile's 3G/3G+ service in some areas that's preventing phones from idling properly.
Anyone else want to give it a try?
Interesting, I'll switch over to 2G only and see how that affects my phone.
I've gone as far as wiping everything and that didn't help so if it really is a t-mobile issue then that would shed some light on the situation.
I see the same trend when switching to 2G only. Very steep power usage with 3G then a dramatic decrease in the discharge slope in 2G.
T-Mobile has an issue. The trick will be getting someone there to listen.

Here is my screenshot. You can clearly see when I turned on 3G. Dramatic difference. Looking on the T-Mobile forum there are many people seeing the same issue but there's mostly finger pointing and speculation as to the cause.

I also got the same rapid battery drain since last Wednesday. At that time, I thought there may be a hardware/battery issue for my nexus one. To test this, I switched my rom from CM7 back to GB stock. After a few updates for the GB stock and used it for a day, same battery drain happened. So, I changed to use another backup battery yesterday. It did not help also. I thought it may be a real hardware issue.
Then, I found this thread and research a bit in the web. I found out it could be either caused by tmobile or google map updates. I first uninstall google map and reinstall the new version right from the market again. I also switch off 3G as well. No rapid battery drain for the entire day. The battery runs normally. When I came back home today, I turned on 3G, let it for a couple of hours, checked a couple of emails and received a 20min phone call. Everything seems to work fine. No noticeable rapid battery drain was observed. My conclusion so far is: this is caused by google map 5.8 update.
Try to uninstall it and reinstall the google map from the market to see if it helps.
Good luck.

Well, I'm willing to give it a try, but I'm skeptical. If it were the Maps 5.8 application that was preventing the phone from idling correctly, or transmitting tons of data, wouldn't we expect it to happen regardless of whether the phone was using the 2G or 3G radio connection? Sure, there might be a slight difference in the drain rate, but we'd still expect to see it in both cases. And yet the accelerated drain is alleviated completely by using only 2G. I have the Maps 5.8 application and can fix the problem by using 2G only. That indicates to me it's not an issue with the application.
I'll try uninstalling Maps tomorrow (I'm using CyanogenMod, so it's possible to remove it completely). Then I'll put the phone back on 3G and report back on what happens.
I've been experiencing similar battery issues the past week or so too. It looks like turning on 2G only seems to fix it, but what I don't get is why I'm still getting horrible battery life?
I have tasker auto turn off my 3G all together whenever my screen is turned off, and yet I leave my phone on my desk untouched all day and I end up at 40% when I get off work.
Wouldn't turning off 3G via Tasker be the same (or close to it) as turning on 2G only in the settings?
Hope t-mobile gets this worked out pretty soon!!
Glad I saw this thread. My wife and I both have N1s and have each been noticing unusually fast battery drain just in the last 3-4 days.
Last night I charged both phones to the same percentage, turned off 3G on hers and let them both sleep for a while. The phones are configured pretty similarly (stock, latest Maps installed, similar push settings etc). After about an hour and a half, my phone had lost 11% of its charge and hers had only lost 2%. That's enough of a delta for me to point to the 3G usage as the culprit. I guess I will be leaving my phone on 2G when I'm not using it if I am going to be away from a charger for a while.
It's NOT the Google Maps update.
Well, I did my experiment yesterday to rule out the Google Maps 5.8 update as the cause of this issue.
I'm running CyanogenMod so it's possible for me to uninstall Google Maps completely, not just the updates. I did so on Saturday night. Still set to 2G only, I removed my phone from the charger Sunday morning. A few hours later I enabled 3G. Later that afternoon I turned 3G off again.
I think the screenshot speaks for itself. Again, this is without Google Maps installed at all.
I asked around this weekend, and my friend's wife (also here in Portland, OR) is experiencing the same issue on her G1 on T-Mobile. Reading online I've heard about the problem affecting the MyTouch 3G, the G2, and many here with the Nexus One. The common elements seem to be: T-Mobile 3G service, particular models of phones, and some particular geographic areas.
Bottom line (IMHO): T-Mobile has a problem with the configuration of their 3G service in some areas, and it's preventing many phones from being able to idle/sleep properly, resulting in huge battery drain.
Here's mine, I posted this several days ago in the TMONEWS thread.

That's interesting. Even locking the phone to 2G/EDGE didn't have an impact? (not a Nexus One there it appears, what model?)
How did you go about disabling the 3G connection? I'm not sure if there are multiple ways to do it, but I used:
Settings -> Wireless Networks -> Mobile Networks -> Use only 2G networks
Really strange that even pulling the SIM didn't seem to make a difference. Or maybe that's not the same as turning off the cell radio entirely? Perhaps the issue is lower-level, like the radio constantly polling the tower or something even in the absence of being able to successfully register on the network for active use.
Does enabling airplane mode fix the drain issue for you?

This is a G2.
2G has been much better than 3g, but still probably only 3/4 of my former battery life, optimistically. I checked "Use 2g networks only", same as everyone else. The graph above is a little misleading, since I really saw better battery life, that initial flat and quick drop actually averages out to "decent", rather than "horrific.
At the "Pulled SIM and SD card" mark I re-enabled 3g, so the drain afterwards is still 3g related.
Pulling the SIM doesn't disconnect it from the radio tower, you can still make emergency calls/etc. so it has to maintain a connection I suppose.
Twice I hard-reset the phone, pulled out SD and SIM, and still had huge huge battery drain. Powertutor said IDLE draw was 1437mw on average, no SIM, no WIFI, just sitting there on my desk.
In Airplane mode it'll last for days...

I'm not familiar with Tasker. However, maybe it's just disabling cellular data use, not actually disabling the 3G radio? From what we've seen it appears the problem is very low-level, perhaps something to do with basic communication/negotiation between the cell radio in the phone and the towers, as there's no indication of particular application activity or significant data transmission that the Android OS is aware of.
In the T-Mobile support thread there are reports that T-Mobile is now acknowledging there's an issue with changes to their HSPA+ network in some areas.
I've had 3G off all day and my battery life is back to normal. I'm at 87% after at least 6 hours on battery. Yesterday I was down to less than 50% by this time. Luckily, I am able to be on Wifi at work so I don't have to deal with EDGE speeds, which make the Baby Jesus cry.
deliamber, you probably noticed this already but I'm also in the Portland market. It's gotta be a network issue.
I'm having the same issue on my N1 (I'm around the Portland area myself)
I did everything as well, 2g is the only thing that saves me..
Can't wait for a fix!
Hi
Can see a number of threads about short battery life, none quite match mine:
When I got the phone about 6 months ago I took it abroad with me in the first few weeks. Battery life with normal usage was about 24 to 36 hours with fair use.
Dropped the phone, back came off, battery fell out and gold contacts got damaged.
Ordered replacement OE battery from Amazon. Looks identical to original. Battery life as before, for about the first two weeks. Then got worse and worse until down to about 4 hours. Sent it back, replaced. Replacement is going the same way.
Haven't done anything with the ROM, it's all as it originally was, albeit I've installed more apps since it was new.
Battery meter thing built into the phone (in Settings) shows nothing remarkable.
What is odd, and coincidental: if I leave the phone next to me in the house, it won't always pick up emails on ActiveSync (Exchange) unless I activate it (e.g. bring it out of power down mode). At which point you can see it's dropped Wi-Fi. The icon has gone. A second or two later it reconnects (though not before it's used some 3G data - 3G is OK upstairs, barely a signal downstairs as we live at the bottom of a hill so often drops to "G") and then brings down the emails.
This means it churns through 500MB+ of data over its own 3G connection in a month even if I don't take it out of the house, and even when Wi-Fi is available to it, it chooses not to use it. Wi-Fi reception is pretty poor, compared with e.g. our laptop (that shows excellent strength downstairs, phone shows one bar). It did not do this when I first got it. Curiously my old HTC phone did this too, it struggled to switch properly between its own 3G and Wi-Fi and just got stuck on one or the other. We are in a weak signal area.
Are these things related?
Has the phone become faulty? (Bearing in mind battery life much better with the original one)
Is it just a duff batch of batteries and I should send the battery back for a refund, and get one somewhere else?
Thanks
Mark
Typical behavior for a counterfeit battery but the other symptoms suggest that something got damaged and is stressing the battery. Try re flashing the phone. A sudden loss of power could potentially damage some system files.
Thanks rogem_kk - can I just clarify, when you say "reflashing the phone" do you mean resetting it back to its original state (I'm guessing there's a key sequence you press, I can look in the manual to find that out) or completely reloading the OS?
As regards "sudden loss of power" sadly this happens quite often, because the phone crashes now and again and I have to take the battery off the back and put it back in again. The Android OS seems able to be completely taken down by a failing application (I think Flash movies on web pages are the main culprits) quite readily but I'd got very used to that since my last phone was a Windows Mobile one (the old one not the new one) which had the stability of a damp cardboard box in a strong wind.
I mean wiping it clean and installing the ROM from scratch. Factory reset only removes your data and does not restore/replace system files.
Now may be a great time to flash a custom rom, if it all goes well then do a back up with Nitrality app or similar, while you're at it try out a modem i9000 ZSJPG, you can flash it separately via ClockWorkMod, doubled my battery usage with it, great reception & coverage, that way if you at least get a genuine SGS battery you'll get the most from it.
If you're unsure of flashing you'll need to get reading in the rom section, not too hard to learn.
Many thanks.
Down to 3 hours idle time now - it drops by the day.
Have emailed Samsung on the off-chance they can identify a counterfeit battery from the serial number, so I'll see what they say. Could make for an interesting exchange with Amazon (direct, not via a reseller or third party).
Argos appear to be the "official" resellers for Samsung products in our area but they don't actually sell batteries. As otherwise I'd be tempted to buy one there on the basis that it ought to be genuine, and compare. But haven't rebuilt the phone yet, waiting to see what Samsung come back with.
Hmmm...
"Problems like this, although seemingly severe, can occur when the
Android software on your phone becomes out of date. You can update the
software by simply downloading our Samsung Kies programme. Follow the
link below and choose option ‘save’. Then for safe installation of the
drivers, once save is complete, turn your computer off for a few minutes
and reboot the PC. Once fully loaded again, without opening any
applications on the computer, simply connect your phone to the PC with
the USB lead, and your phone should be automatically set you finish the
installation of Kies. When Kies loads and finds your device, you should
be offered an update that will iron out these issues.
If you require any further assistance, please contact Samsung again and
we will be more than happy to help."
I had one of those so called 'original batties' it was a load of rubbish. Still using original one but its no holding charge for as well after a year of use. Maybe time for a real replacement...

Forgive the curtness of the email, am at work typing one handed while chowing down lunch
First point - you dropped your phone. I know that the new battery went okay for a while but is it possible that the phone itself may have been damaged?
Secondly, Email on Activesync over 3g will absolutely smash the hell out of your battery. Especially if you have push email going. Is it on push or is it set to check every so-and-so amount of time? Too short a period will kill the battery. The "Stock" email app that comes with Gingerbread 2.3.3 or lower seems to be just a big hog over push (for me at least). I also recommend changing the email "Amount To Sync" to a shorter number of days and set the amount of data to a lower value than stock (ie, "Headers Only" or 50k or something) so you download attachments on **your** terms.
Thirdly, you state you're in a poor reception area. This will most definitely affect the battery as the phone on a low signal or zero signal will waste battery trying to reconnect to the tower. Check your "Cell Standby" and see how muck time without connection you have. If it's anything above nothing, it's draining your battery. I recommend flashing a new modem (you'll need to investigate which one is good for your region/country/carrier) through ODIN (or Heimdall). Be careful when doing this and make sure you read up on the hows and what-to-do and what-not-to-do before you do - there is a (small) chance of you killing your phone and I do *not* want you to come back onto this thread and say it blew up (I want you to say "YAY THANKS WOGFELLA" ) Doing this voids your warranty so only do it if you either don't care or you really really want to fix your issue (and by default you don't care)
Fourthly, your wifi coming on and off - go to your Wifi settings, press your menu button and click ... advanced? Can't recall exactly (on ICS now). From there you can set your "Wifi Sleep Policy" to either "Never" or the other option that I can't recall. The default is set to turn the Wifi off when screen is off which of course means you lose your Wifi connection. **For your Email issue, try this first.**
Fifthly, your Wifi signal being weak in your display does not *always* equate to an actual poor connection. Sammy does many great things, but he does mess about a bit with icons and funny business. Check step four above and if you get bad Wifi reception when the phone is off (or while using it) then try messing about with your Router settings and also with the settings on your phone (take notes before doing so, I'm just throwing you ideas here....don't come back to me and ask me how to reset your router settings either!!!)
If that doesn't help then try flashing a custom kernel (kernel controls the Wifi). As above, doing this will void your warranty.
Sixthly, you say that everything was hunky dory and then went haywire. I reckon there may be an app doing funky things.
Try installing CPUSpy from the market and check to ensure your phone is going into decently long periods of "Deep Sleep"
Also, try installing the below app from this thread.
http://forum.xda-developers.com/showthread.php?t=1179809
You're looking for high "Wakelocks" which will impact on your phone being awake instead of...well, asleep...when the screen goes off. Awake phone = cpu processing (even if it's not doing anything) = battery drain. Use Chamonix's recommendations on what is classed as a high amount of wakelock.
Facebook 1.7 for example, keeps the phone awake while checking notifications that just plain ain't there. For me, once I wiped this app, I regained about an extra 2-4 hours per day in use.
Seventhly, look over this thread:
http://forum.xda-developers.com/showthread.php?t=939752
Has a heap of tips that helped me (before I got sick of stock Sammy and jumped to CM7 and then ICS)
Eighthly, and this is one that probably doesn't need to be said - cycle your battery and (controversial) bump charge. I mean, let the battery drain fully. Take the battery out for 5 mins. Put it back in and see if it turns on, and if it does repeat. Then fully charge to 100% and then unplug and plug back in. If your phone is already rooted then you can also wipe Battery Stats from Recovery.
Lastly - have you tried factory resetting your phone? It may wipe whatever it is that's making your phone freak out (if not the email) and you can start again. If you find that the battery goes bananas again after installing that app, you've found your issue.
So...to sum up:
Check your phone contacts.
Check your Wifi sleep policy.
Check your Email update rate.
Check the length of time you have the sync set for,
and the amount of data per email downloading.
Check to see if you are going into deep sleep.
Check to see if there are any apps holding wakelock (and bugger them off)
More extreme:
Factory reset.
Mess with your router settings if your wifi signal is still weak.
Very Extreme.
Flash Modem
Flash Kernel.
One thing not specified: What version Android are you running? SGS comes from Eclair up to (once Cyanogen and TeamHackSung get it rolling properly) Ice Cream Sandwich.
Hopefully *SOMETHING* in the above helps you.
Good luck!
Thanks for taking the time.
Sorted out the Wi-Fi sleep issue, CPU Spy showed the phone was going into deep sleep when idle, so no "smoking gun" discovered with that.
Reset phone, and set it back up again with basic email and no new installed apps. Have left it on default (minimal) donwload settings. Had already got rid of Facebook.
Battery life is better. Have begun reinstalling a few apps now and keeping an eye on it.
Will report back - thanks again all.

No dramas - just be careful as CPU Spy will show length of time in deep sleep but a high proportion of wakelocks won't really be detected and those wakelocks are the ones that smash your battery when sitting "idle"
As you have reset then I think you need to let your battery calibrate first (let it drain fully and recharge fully a few times and that's all you can do if you haven't rooted your phone)
.. one more update..
Battery life is better, but not much better. It still won't last a day without charge even with very light use, 7 hours is about the maximum. I'm certain it used to be better than that when I got it e.g. it survived a whole day on holiday using email and maps quite a bit.
Have changed to 3 from O2 but will have to revert back as 3 doesn't get a signal at all downstairs in some parts of the house. Does mean the phone is going on and off network a lot at the moment.
I reverted to Samsung to tell them their link didn't work and they have sent a link to an authorised dealer for parts if I wanted to buy another battery. I'm all for buying the real thing which is why I bought an (apparently) OE one from Amazon which was about £16 not the £5 that some were.
However this is, er, forty four pounds for a tiny little battery.
http://www.4mysamsung.co.uk/cgi-bin/product.pl?PID=2986318&brand=&model=galaxy s&part=
They also sent links to repair centres.
Now I plugged it into charge earlier, and even after 8 hours, it was dead. Plugged it in again - beeps once as normal - nothing on the display - still not charging. Take battery out, put back in, repeat. Charging now.
Might make you wonder if that part of the phone got damaged e.g. the "socket" where the mini USB thing/charger goes in, but, it's always worked before. It doesn't for instance fail to detect if I plug into the PC and it's never done this before either.
Given how much the battery is and the fact it might be getting to the point of dying altogether I wonder whether to just get a quote for repair and go that way for certainty.
One might have thought it's as simple as: take the thing somewhere and have the battery tested to prove one way or the other.. but I'm really not sure where would do that other than the repair place.
I'd be prepared to try replacing the OS as suggested, but it does remain the fact that the thing worked better when I first got it and even after a complete reset it's still playing up so I feel a sort of mental paralysis over what's best to do now
I'll have a look at the wakelocks thing next when it charges again. If it charges
Firstly, please don't bombard me with the check apps responses and the like. I've been running down apps and processes for 2 weeks. I went from being able to use my phone all day with gps on, wifi on, email syncing, and all that good stuff, and still have plenty of juice left after a full day. All of the sudden my phone is draining so fast that it will barely make it overnight (unused). From around 12:30am- 6:30am my phone went from 78% - 2% and was in deep sleep for around 5hr45min of that time. There were no changes or new installs during the period when this started happening. I actually have two Bionics (hwd A & hwd C versions) that were RDlite back to stock ICS within one day of each other (months ago), with not much done to them other than root and unlocking sim. Both started exhibiting this behavior around the same time. Killing apps and background processes and services make no difference at all. The excessively quick drain continues even when in deep sleep. I haven't done another reset, but from what I've read up on the issue, that procedure hasn't helped anyone else who've started experiencing this same problem?
Any suggestions beyond the same ol' 'check your running apps and cpu use'. Something is wrong beyond apps keeping the phone awake or active when the issue continues while in deep sleep.
Your phone is obviously not in deep sleep if it goes from 78-2% unused overnight. Either that or both your batteries are failing at the same time.
Betterbatterystats is telling me it's going into deep sleep. I didn't think so either, for the obvious reasons, but it does without any excessive delay when the phone is left alone. Andriod.os battery use is always in the 60-80% range unless I'm playing a game or something that you would expect to eat up an appreciable amount of cpu cycles. I have 10 instances of kworker/u, is that many normal? 6 of those seem to dominate the energy consumption by android.os. This is the only thing that I've found that stands out. I may be wrong, I don't know much about linux, but I thought that I should also see some type of activity from an app associated with higher kworker activity and/or that many instances running. I admit I'm assuming more than anything else there though.
I find it more plausible that my issue is more related to an issue which seems to be common across a broad range of users, than 3 batteries tested in 2 different phones suddenly acting abnormally, but all in an identical fashion. I don't think it's hardware related either. Two different hardware revisions! Highly unlikely to phones manufactured so far apart would start to exhibit the same hardware related issue at the same time. It would be more likely to occur over a similar period of operation or age in that case. The only common factor, other than when the phones started exhibiting this problem, is that they were flashed back to stock ICS within a day of each other around Feb or March.
I suppose it'd be really rare that this would happen on both phones but is it possible the batteries are just trashed? Try a new one?
Granted, I'm only on day 4.. but still..
I've tried disabling LTE, simple watch-face, etc.. but can't get it to live for more then 12 hours without needing a recharge..
Do those of you reaching more then 12 hours use an always on screen? Gestures?
I did do a test overnight and it only dropped 20% (7 hours) - but my typical drop rate is much higher then that with casual use..

ps - I'm on-track for 12 hours again today, and that's with only having received ~3-4 email notifications which I just quickly dismissed in the past two hours so far..
For those that might be interested in this subject, I also posted it on reddit which seems to be getting much more traffic..

I just put mine on charge after 48 hrs with 3% left that is with screen always on off and only turning WiFi on when needed.I'm using mine tethered to my g6 without lte.
Firstly in my case I don't use LTE.
I've found having WiFi and gps switch on has made very little difference to battery life, as it's tethered anyway for this information.
I think the battery life has got better after a couple of weeks usage, and typically a full day has plenty left, nearly 50% on occasions.
Yesterday was a long day, and it managed 20 hours straight through
I usually get around 24 hours. But barely 24 hours (if I do anything except let my watch run idle on my wrist whole day, I don't hit the mark).
Screen always ON
NO SIM (doesn't even work in europe)
Always tethered to the phone
Tilt OFF
Gestures OFF
Location MIXED (decided to experiment a bit, seen no discernible difference in battery drain whether it was ON or OFF)
Watchface: Portions with 4 complications
First couple of hours is sleep tracking with screen turned off (but constant HRM sensor activity), which consumes slightly less than regular operation.
Today I turned always screen off and holy **** what a difference. After 12 hours I'm still at 80%. So the clear culprit of this is the screen. I think I will try to get used to this, it was wasting energy 99% of the time before anyway (I'm not looking it at it all the time).
I end up getting through the day at about 30 to 50% with everything on except for LTE which I toggle on and off during the rare occasions I need it. I usually use brightness 6 during the evening and 8 during the day, I find the auto-brightness too dim on every occasion. On the other hand I've had a few random days where it rapidly used it's battery and I was down to power saving in the afternoon. Havne't figured out what is happening when it occurs but when it happens my phone also rapidly drains. Other than that I wish I could increase the screen on time, it sometimes dims before I've done what I want to do and I feel like I have enough spare bat to burn a little more keeping it on longer.
My Answer, you don't. I leave everything on and charge it, like 3 times a day. I'm lucky because I have two others to swap to during charge, but I even bought a second charger for work when I do not have those available.
I simply do not want to reduce any features of the watch, so I charge it often. That's just what it is if you ask me, you're not going to miraculously get this thing working for 2 days, simple as that. So use it big, and charge it often!

Is there a faster way to toggle cellular on and off other than going into settings?

Not that I know of and for me it's a double downer, when I use the watch standalone I don't need bluetooth. I menu dive to switch both and then revert when I'm done. The radios should be available from the pull down quick settings IMO, it would be enough to have an icon there to open them all and you could toggle those you need from there. Considering the wasted space on that pull down it becomes a bit of a what were they thinking issue...
Hi guys i'm interested about lg watch sport here in europe and i'm willing to buy from ebay korean model. My cuestion is can i use it completly without pairing to phone with sim inside. Can i set it up without cell phone? How about using facebook, viber ( making VOIP calls) email etc... thanks

You need to pair with phone initially. It also makes it easier to copy your accounts over to the watch. After you set it up, you don't need your phone anymore BUT if you keep it on cellular the watch isn't going to last.

From my time with the watch it appears that having cellular on has little impact on battery life as long as you're within range of your phone. The part that does affect battery life with cellular on is IF you're in an area with just complete sucky cell signal to start off with. (IE my workplace) that will kill battery.
I had battery draining issues at work even with cellular off at work but I figured out that although on my phone when connected to work wifi I can get to the play store on my phone but on my watch it can't get to the playstore or communicate with google. My assumption is the watch is draining because the google play services can't connect/sync with google therefore causing it to stay awake and drain. Watch battery life has been much better when I disable wifi on my phone BUT now my phone drains a little faster because it's not on wifi.
Bluetooth Autoconnect app has been a lifesaver when having watch/phone/BT headset/BT car connected. You can set up profiles and priorities so that the car/headset/headphones take over the call duties so you can hear phone calls through those devices instead of the watch.
I'm still getting used to life having to sift through the menus to disable and enable radios but you're right. There needs to be an easier and faster way.
