Seems to me, it takes more power to send a signal on the mobile network than on wifi,
Iv never turned wifi off, (have it at both home and work) and my battery lasts well over a day?

You're probably right if you're not in the best coverage area. My HD2 at home lasts much better connected to my home WiFi than it does trying to maintain a cellular connection in our poor coverage.
If I turn data off battery does well. If I have 3g on it does really bad. WiFi, battery does well again.
I was in Austria 2 weeks ago battery lasted great with 3g on because signal coverage was 100% pretty much everywhere!
Hi... I have an Xplay rooted on 2.3.4 and removed light bloatware, but still my battery drains fast...
I must charge phone every day and I dont use a lot of heavy gamming... I only play in bed at night and normaly to drain the rest of the battery before charging.
I almost never use 3G, but have always wifi turned on...
So, resuming, my battery only lasts about 12h-14h per day...
As you can see, in the attachemt I have 2 times the same thing (portuguese language, but will translate):
- Inactividade do telefone 28% (Inactivity off phone)*
- Wi-Fi 21%
- Telefone inactivo 15% (Phone inactivity)*
* This 2 things arent the same?
I have a few questions:
1º - I have read about people who can have phone about 2 or 3 days, others with 20h or more. What is the most accurate and normal on this phone?
2º - If wi-fi always turned on, will drain battery?
3º - Why most off % is used when phone is inactivity?
Sometimes the phone dont loose battery when "sleeping" (it take 2h to loose 1%), but other times, when sleeping, battery drains 10% or more in one hour. I have read about a bug in Android OS that drains battery when phone sleeping. Does this bug applys in ALL ANDROID phones, or only Samsung? Read it on here: http://forum.xda-developers.com/showthread.php?t=1290020
If I charge phone every day will get battery "addicted"?
One thing im shure: the 3 first itens on the screenshots are draining my battery whitout a reason (i can understand wi-fi, but can't understand why 2 things saying phone inactivity, uses 43% of battery)
In that screenshot, battery is on 60%, so I losted 40% in 6hours with 20 minutes of gaming... and on those 6 hours, almost half, phone was "sleeping", again, it shouldnt drain battery when sleeping.
Thanks in advance for your help
What's shown as draining your battery the most is your phone's cell standby (your 3G & 2G network, or 4G if you have it). The third on the list describes your phone when it's not in use (screen off). Don't worry about that one, a higher % only means your phone is often in standby.
Having Wi-Fi on will often use more battery than using your phone's own network. To save even more battery, turn off 3G connectivity when you're not using it (you will still receive calls, just no internet, but you use Wi-Fi anyway).
Charging your phone every day is perfectly fine, just make sure you unplug it once it hits 100%. If you leave it plugged in while it's fully charged, it gets bad for the battery after a while.
That article about the battery drain in standby is likely just for Samsung devices. What is likely draining your battery are apps and services that run in the background and use the internet while in standby.

95% of the time, 3G connection is OFF. I use Wi-fi connections, because I have many hotspots for it...
I don't have many APPs and the ones that I have installed (non-stock apps), dont run in background.
Today, I turned off wi-fi, and only turned on when need, and for more than 2 hours, only losted 1% of battery (have takken photos, and made phone calls only).
After this I used wi-fi for 20 minutes, and losted 8% off battery. So I think, Wi-fi is the problem. Please correct me if im wrong:
- If I have wi-fi always on, phone is always searching for wi-fi connections, even when sleeping, so battery drains much faster.
As you can see on the screenshot, with no wi-fi, for a little bit more than 2hours, only 1% of battery losted
Well you answered your question. Wifi is the problem. If it searches for wifi networks all of the time the battery will surely drain.
Definitely Wifi. It absolutely murders my battery when I forget to turn it off when I'm not using it.
Yes... for shure... its crazy like hell... lol... half an hour playing... half an hour surfing (youtube for my son... i put videos for him, once in a while)... and wi-fi drained more battery than gamming (FIFA 2010, Angry Birds, Spider-Man... also my son played)... funny thing, he has 20 months old, and love Xplay, more than me...
So... the hole day, I kept wi-fi turned off, and only turn it on, when needed... more than 12h latter, still have 62% off battery... and for the first time, will not charge this night...
Was so simple, as turning wi-fi off... check the screens...
Thanks all that helped
My battery usage for WIFI has never gone above 3% and has only hit that once, normally it is 2% no matter how little or much I use it. What percentage of your battery life is used by your WIFI?
I'm just trying to figure out if the number is accurate and using wifi really does save my battery as much as it appears to do so.

I've never really bought in to the whole Wifi saves battery power....I've had the Captivate and now the GN and anytime I leave Wifi on at home, my battery just drains faster. Here is an example, if I leave Wifi off, I've reached about 40 - 48 hours on one charge. If I take my phone off the charger at 6:00am....go to work with Wifi off, come home at 4:00pm and turn Wifi on, by the time I go to bed at 11:00pm my battery is at about 40-50%. In the first scenario with Wifi off, my battery is usually around 70% when I go to bed the first night.
In both of those scenarios, the phone is only being used lightly, but I do see a huge difference if I use Wifi in my overall battery drain. So pretty much these days I just turn on Wifi when I actually need it....but having a 6GB data plan helps in not caring when I use Wifi (for the day to day stuff).
I only use WIFI at home but otherwise have it off. I use Y5 to automatically turn in on when I'm home and off when I leave. It seems to really help me save my battery when at home though since my coverage is spotty since for some reason I cannot stay connected to 4G even though I'm surrounded by the coverage.
That's why I'm asking here if the meter is actually correct because even on the weekend if I'm home all day the meter never shows anything other than 2% after a full days use of downloading apps, surfing the web, messing around on Facebook, and reading things on forums. About 43MB worth of usage and 14 hours and 40 minutes of connectivity to WIFI.
Hi
This has happened a few times now when my phone is in a place with barely and quite often no mobile signal, always the same place, same building that is in a bit of black spot. On coming back to the phone after an hour or so I've lost 40-50% of battery power, and of course the phone is warm because of the more rapid drain of power. It is the warm phone that alerts me that I've probably had a massive battery drain event again, turning on the phone shows no service, the service comes back fine as I walk away from the building. This rapid drain event never happens elsewhere, but then normally I'm getting a decent signal everywhere else.
The battery chart shows the drain clearly, and as soon as the phone is back in a decent signal area the drain immediately stops and is back to normal battery usage apart from having lost half of its power.
The battery usage shows the phone was hardly sleeping for the duration of time in the low/no signal area, presumably kept awake by the radio chip constantly reporting no signal or something like that.
I'm using the stock ROM in Europe on Vodafone, software version 1.29.401.11.
Surely it isn't normal for the radio chip to cause so much battery drain in a no/low signal area, where is it trying to reach for a signal, Mars? :cyclops: My other smart phones same carrier in the same place with the same no signal situation were absolutely fine and didn't do this.
Interestingly the cell power usage percentage doesn't increase for this problem, so while the cell power usage is half the battery when this event occurs, this doesn't register in the cell power usage percentage, or anywhere else for that matter, just the overall chart takes a dive down.
Perhaps this issue explains variable battery life some are experiencing if they are in or travel through areas of poor or no mobile signal. Something isn't quite right with the way the radio is dealing with this situation, hopefully fixed in the next update.

Same thing is happening with my 1X. I'm working in such a building too for the last couple of weeks, it's very annoying.
I'm also on Vodafone from the Netherlands

On Vodafone in the UK and also get bad drain when signal is poor. Signal does affect battery drain though.
Same when the phone is resting in a low wifi signal with wifi on: massive battery drain in that case. Extremely annoying!
Hi
I've updated my One X with the newest RUU that contains the latest radio 2.120, this is a stock ROM for European unbranded phones and installs without needing a rooted phone.
This radio was pushed to some places in Europe last week I believe but we haven't had it in the UK.
I'll see how it goes, but it is very annoying and certainly not right for a low/no signal to drain the phone so quickly.
Regards

Just picked up an old Play for gaming and the phone functionality is broken so I got it for cheap. The issue is the cell standby keeps draining the battery like I was only getting 3 hours with OC and gaming with cell standby taking up 25% of that. I can set it on airplane and that solves it but the WiFi goes on and off or sometimes doesn't come on.
Is there a build.prop edit I can do to make it think it has no phone hardware inside?
Thanks in advance,
