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.

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!
What is everyone's cell standby battery usage, percentage wise?
Mine is 41%, which seems a bit much.
My battery is down to about 30% in about 6 hours (most of which was in standby).
I'm trying new roms and kernels, so I'm trying to determine whether or not that's the problem.
Today mine is around 34% and I have seen it as high as 41%..After almost 13hrs still at around 65% battery but I've been light on my phone today.
I've been incredibly light on my phone today.
When in some of my classes, I have horrible/no service. I'm thinking that has a lot to do with it.
Are some ROMs or kernels more heavy on the battery when not in service than others?
With my stock rom and kernel, my battery didn't last long, but it was much better than this.
Im usually about 41% also seen as high as 43% but only once....as long as your time without signal is low I don't think its that big of deal..but, if they is a way to lower it without goin into airplane mode would that help battery life?
Well if you guys' cell standby usage is as high as mine, then I guess that it isn't the problem.
I was just asking because it seems like I remember hearing that some phones increase Tx power when they don't have service in an attempt to get a signal.
Mine cycled through 1 bar, roaming and no service for about 50 minutes while in class today.
Maybe I'll just try different ROMs and kernels and find a combination that works for me.
~7 hours of use isn't cutting it since I was getting significantly more time with the stock ROM.
Thanks, guys.

A typical battery usage in standby with only 3G on (mobile data always on = off, gtalk = signed off) should be between 1-2%. In 6 hours of standby, you should not have lost more than 6-12% of battery charge. A full charge should be sufficient for about 3-4 days of standby.

That's more like what I'm looking for. What am I missing?

He is not talking about the same thing we are.......he is talking about actual battery usage via battery icon, not the settings, about phone, battery, battery use screen.
I get approx the same battery use few % an hour with phone standby @ 43% of total battery use as long as I have a good signal and not using the phone
Two different things dont get confused.....
JuiceDefender has done the trick. I'm at about 45% battery remaining 8 hours and 2 minutes after being unplugged with 35% of the damage attributed to cell standby.
The only caveat is that Gmail and Google Voice don't push instantly. Of course 15 minute intervals are enough for my email, and a simple text upon receipt by Google Voice lets me know exactly when I get a voicemail.
Thanks all for your responses.
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.
Regards
Phil
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
Sent from the HTC HD2
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
Phil
I have myself a rooted Note 2 with Wind Mobile. This is the weird part. When I'm at home/not in the downtown core, the battery life is amazing. Keeping in mind that my signal at home is horrible. I average 1-2 bars. If I'm absolutely not using the phone it will drop about 1% an hour. If I'm using it, maybe around 2-3% an hour. Which I am not complaining about, I am very satisfied with these numbers. However this is only in the city I live in. On weekdays when I have to commute to school, my signal is amazing, Always 4 bars. I turn off wifi, and yet I realize that if I don't use the phone, my one hour commute has consumed 5 percent of my battery, doing absolutely nothing. I have noticed that the phone is hot as I take it out of my pocket. I have wake lock detector and it says that my phone has been in deep sleep for only around 6 percent. But when I look at the apps there is nothing that is eye popping. I have greenify to already kill all those apps that eat my battery, facebook etc. So I don't understand why the battery dies so much faster if I go downtown as oppose to staying in my city. Wind doesn't even have LTE so I know that's not the issue. I've had my battery last me 2 days before with mild usage at home. If I go downtown it'll last me maximum 12 hours. Whats keeping my phone awake as I leave the city??!!
Thanks for any help

come on dude...you've got to make it short next time
happened to me when I first got my N2...but the problem was gone after updated to the latest firmware.
i believe it's 4.1.2 BMD1
