Do losing signal drain battery?

Do losing signal - and searching for signal - drain battery? What makes me think that is... when I'm on the train for a few hours and signal comes and goes, my battery goes down even quicker than normal!

yes it does. Having a consistently strong signal will give you better battery life than having a sporadic signal as your phones radio will search harder for a signal. You might want to turn your phone to 2G only to give you better battery life when you're in a low signal area.

You're not on O2 by any chance are you?

Yes I am! Well, giffgaff, but they're really the same right?

Ahmad is right.
For that reason it is so very clever to switch off 3G when you're in an area without 3G coverage. On some phones disabling 3G alon can double your battery life.

Doesn't surprise me, O2's 3G is truly shocking. The coverage is awful, it's because they were still farting around with Edge until the release of the iPhone 3G in 2008.

Matt is right. The reason i asked was because O2 have terrible coverage on trains for me when i go from paddington to reading/slough as well as numerous other train journeys. I have an o2, Three and T-Mobile handset and the O2 one always loses 3G signal when out of cities or travelling.

If you don't use your phone for the browsing on a train then you can turn off 3G and just use 2G only. It should be an option in the settings. And theoretically you can get much longer battery life.

Also, what phone do you have? I bought an extended battery for my phone last year for about £10. It had over 120 5* reviews on amazon and extended the standard battery life by at least 25-35%. So you might be able to get a similar extended battery for your phone.

Oh, same here in Ireland. Their total coverage is good - ie, you're hardly ever without a signal, but their 3G is sucky. Totally random wherever, whenever

Exactly the same here in the UK. Their 2G coverage is pretty much nationwide, but their 3G is simply terrible. I don't see how GiffGaff (or Tesco Mobile) ever got so popular. It's case of you get what you pay for, and not paying very much gets ypou a crappy 3G signal in many areas of the UK

Because many people don't know the difference between 2G or 3G and many people now accept that data allowances and speeds are meant to be that low and 500mb is enough/their unl plan is actually unlimited etc... and that wi-fi is the more accepted way of using heavy data on a smartphone.

An example is how lots of people still call the uk network Three, "3G". and how many networks like o2 get away with 250mb data + wi-fi plans at about £30pm.

Some people are just oblivious to how bad o2's 3G network is though, and they just promote giff gaff because it's cheap, or keep using o2 because they've been with BT Cellnet for years and haven't tried the other better 3G networks.

Don't get me wrong, o2 is great (otherwise i wouldn't be with them.) But in terms of 3G coverage and Data allowances they are lacking behind.

tbf those 'wifi' plans are bt internet open wifi ;) its not what some people on hukd keep saying that 'wifi is always free'.... hehehe

Yep, thats what i mean. Even when you're out of your home you are still encouraged to use wi-fi even though you should be able to get a 3G signal and be able to use that etc...

O2 still state that 500mb is enough for the average user where as actual reports state that average users use about 1.2GB.

To get a minimum of 1GB on o2 you have to pay £31pm+, to get more than 1GB on Three you have to pay a minimum of £13pm+

true but no 3g signal is as good as a decent wifi hardline signal..

I do love 02's on and on plan...
£36 for unlimited texts/mins but 1gb of internet... i mean really???

Agreed^
T-Mobile's and Three's all round plans are much better value at roughly the same price for high end phones but with more data allowance.

Going back to my previous point about people not knowing the difference between 3G and 2G. I've seen a number of people comparing signal by looking at the number of bars and totally ignoring the fact that one phone says H and the other says E. And i've had a number of people ask me why their phone never has 3G and only has H :P
