Watch Your Network Signal, It Will Hurt Your iPhone 5′s Battery Life

Having a weak cellular connection could mean your iPhone won’t last as long between charges,

How’s your iPhone 5′s data connection where you live? Did you know that if your signal is poor, and your handset is always struggling to get a decent data connection, it could mean that your battery life won’t last as long between charges?

That’s according to iLounge’s review of the iPhone 5, which looks at the handset’s battery life performance. Although they found that battery life is almost always fairly good on Apple’s latest smartphone, more power is consumed when you make calls or transfer cellular data over a weak signal.

if you’re using your iPhone 5 in places a with a very strong (4- to 5-bar) LTE or 3G signal, your cellular battery life may approach that number [8 hours], but if not, the cellular antenna will struggle to maintain a signal, and fall well short. Because LTE and 3G/4G towers are in a state of build-out flux right now, our tests suggest that many LTE users won’t come close to Apple’s promised numbers.

Of course, battery life is always a relative subject, because so many different factors can have an impact on it — including the brightness of the display, whether or not Bluetooth is switched on, and of course the general health of the battery itself.

What’s more, this type of thing isn’t new to the iPhone 5 — or indeed just the iPhone; it’s common among all mobile devices. Think about it: having a weak signal means your iPhone has to work harder to maintain a good connection, and it’s always searching for something better. In addition to this, everything you download or upload takes longer, which is directly impacting your battery life.

Personally, I get a full (five-bar) GRPS connection where I live, and I’m always connected to my home Wi-Fi network. Under those conditions, my iPhone 5′s battery life has been incredible. I’m charging it every other day now, whereas my iPhone 4S had to be plugged in every single evening at around 9 p.m.

SignalRefresh Promises To Boost Your iPhone’s Weak Network Signal [Jailbreak]

Full signal a rare sight on your iPhone? Try SignalRefresh.

Struggling to get a decent signal on your iPhone? If you’ve jailbroken your handset with the latest Absinthe 2.0 release, then you may be in luck. SignalRefresh is a new, $0.99 iPhone tweak that promises to boost your signal strength to give you “the strongest possible voice/data signal at your current location.”

As you move around with your iPhone, you device is busy jumping between cell towers to try and establish a strong signal, ensuring you receive incoming calls, text messages, and Facebook pokes. The problem is, sometimes your iPhone can’t keep up with you, and it gets stuck trying to find the nearest cell tower.

SignalRefresh simply refreshes its connection, forcing it to reconnect with the nearest, strongest connection. The same results could be achieved by rebooting your handset or switching into and out of airplane mode. But SignalRefresh makes the whole process quicker and easier.

It almost sounds too good to be true, but according to those who have tried it, SignalRefresh actually works pretty well. I’ve been using it myself this morning, but I already have a pretty good iPhone signal in my town, so I didn’t really notice any changes. But Redmond Pie reports:

SignalRefresh does exactly what it says on the tin and in a lot of circumstances will provide a noticeably stronger signal for a certain subset of users.

Once installed on your device, you’ll find an icon for SignalRefresh on your home screen. When your signal strength is poor, simply open it up and let it do its thing.

This $0.99 tweak is available to download now via the BigBoss repo within Cydia. Let us know how it performs on your iPhone.

iPhone 4S Users Around The World Report Frequent Loss of Service For No Apparent Reason

It seems early iPhone 4S adopters the world over have discovered a new issue with Apple’s latest handset. No, it has nothing to do with poor battery life, but rather a complete loss of signal for no apparent reason. To be clear, this isn’t a new “antennagate” — the issue does not occur while holding the device in a certain position — it’s a new problem that causes the device to lose its signal randomly. Users report they can be enjoying a full five-bar signal one minute, then be greeted by that frustrating “No Service” status the next. One user, who started a lengthy thread reporting the issue over on Apple’s Discussion forums, can’t understand why his signal suddenly vanishes on the device, and there’s little he can do to restore it:

I’ve been using an iPhone 4 on a Vodafone contract for the past 16 months and just bought an iPhone 4S direct from Apple. It arrived on Friday morning and I got it set up correctly as far as I can tell. When I first turn it on, it works lovely and exactly as I would expect, able to make calls, send texts and access the internet via the cellular network. However, at what appears to be random, the network will disappear (no bars of signal) stopping me making calls and texts, but still allowing me to access the internet. Sometimes, the internet goes, but I can still make calls and texts. Other times, everything is gone and I get “No Signal” where it normally says Vodafone UK. So when trying to fix this problem after it’s noticed, I try putting it into Airplane mode and back out. The phone scans for a network and goes back to the same state as before I tried this fix. I have tried resetting network settings, but this doesn’t change anything. The only thing that actually fixes it temporarily is turning the phone right off and back on again.

Razorian Fly reports there is a temporary fix that has worked for some users, which is to turn off the ‘SIM PIN’ feature within the Settings > Phone menu. Because this often fixes the issue, it suggests it is a software bug rather than a hardware fault — as some users have been suspecting:

It’s not a hardware issue, it’s software. For some reason, iOS is cycling the radio on and off, I’m guessing something mixed up with SIM pin permissions. What I had to do was turn on SIM pin, then off, at which point it demanded the PUK code. I was able to get it online through my ATT account. After I entered that PUK, then went back into settings and turned SIM pin off, I haven’t had any problems.

Strengthening this belief is a report from one user, who claims the issue didn’t occur until they installed that latest iOS 5.0.1 software update:

I think I have cracked it. I have read every post and comments and tried and every possible fix. Does not work. I’m using iPhone 4S 16gig bought from Melbourne, use in Cambodia carrier Mobitel. Issue, no signal. 3G come and go. I have to on and off to get back signal sometime aeroplane mode on and off. My iPhone is useless. It was fine on 5.0 problem only exist after I update to 5.0.1.

Whatever the issue may be, it seems Apple needs to address it promptly. The volume of complaints on its forums about the problem suggest it is fairly widespread, affecting a large number of iPhone 4S users. A TUAW reader also claims that European carriers “cannot handle [the] amount of complaints.” While we have no idea what’s causing the issue, it does seem to be affecting iPhone 4S users only. There appear to be no reports from users with earlier devices who are experiencing the same issue. Have you been experiencing this issue on your iPhone 4S?
