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!

As someone who is very happy with the battery life of my Tilt2, I have spent
the weekend in an area where 3G is not available and was wondering if all the
reports of poor battery life are the result of being in an "edge" area and the phone constantly searching for a 3G signal?
When I hit the sack at night in a 3G area, battery 100%, weather checking every 30-45 minutes, in the morning, it might drop to 98 or 99%, but the last
two mornings, in an edge area, the battery is down to 65-70%.
Like I said, I never worry about battery life, since most of the time I'm in a 3g(H) area, but wouldn't turning off the 3G radio extend battery life?

Yes, indeed. If you turn off 3G you get better battery life.
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.
So now my father's phone appears to drop about 70% in 24 hours. The sad thing is it happens with no usage at all!! In fact the Wi-fi, mobile data, GPS, bluetooth were already disabled, brightness set to nearly-minimum and SetCPU to ~300MHz.
I checked the battery usage and this is what I found:
41% Cell standby (time without coverage 0%)
37% Phone idle
...
What should I do? I fail to believe that battery is suddenly so poor because not too long ago it, according to my father, it could stay for like 3 days.
ROM is quite old CM7.
Low coverage area? Phone will constantly search for stronger signal. Last week I was on top of 21 story building with poor signal all day, bursted through my battery easily in 4 hrs.

I believe that batteries can sometimes go from good to bad almost instantly than gradually. So I'm really not surprised that the battery runtime went poor all of a sudden.
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.

Heyo,
I live pretty far away from the nearest Cellular tower and because of that my phone uses a lot of battery trying to connect to it and trying to get a stable connection to it. I do get sometimes 1 bar but because of this, my battery runs out fast. I've turned of 4G/LTE.
My question is, is there any zip or files I can use to somehow fix this where it would use less power connecting to the cellular network? Because of this I wake up the next morning and my phone used 20% battery. I don't really want to use airplane mode because I get txted a lot. I know that my other phone (S3) uses only like 6% of battery overnight with Cellular on and at the same location.
Thanks.
