Convert iMessage to texts?

Your senders need to have that feature enabled. Settings>Messages>Send as SMS.

Leave it to me to miss the obvious!

I could but that degrades the battery (and considering it's 3 months old and doesn't last a day I don't want to make it even worse!)

No, it doesn't hurt the battery to leave it plugged in all night.

Many internet articles say people are kidnapped by aliens.

Read Apple's recommendations on battery usage:

No where do they indication that charging overnight is bad. The charging circuitry in the iPhone will stop it from accepting more charge when it reaches 100%. You may also want to review the article to see if it can help you with the actual causes of your battery issues.

Best of luck.

It is not possible to overcharge an iOS device. The charger is not the thing in the wall outlet, and not the cable. It is in the phone. It "knows" to stop charging once the battery reaches full charge. It's easy to prove this with a US power meter (http://www.amazon.com/Centech-USB-Power-Meter/dp/B00DAR4ITE/); if you use one to measure the charging current you will see that it goes to ZERO when the device reaches full charge. I have such a meter and I've done this test (and many others).

I've had 5 iPhones and 2 iPads in almost 8 years. My oldest current phone is a 3GS, and it is still going strong. As is my 4S. I have always left them plugged in every night, overnight, so they are fresh at 100% the next morning. It has never harmed any of them.

Maybe it's a problem with phones or computers from other manufacturers, but all Apple battery powered devices have the same charging technology that prevents them from ever being overcharged. At the moment I'm writing this on a Macbook Pro that has been plugged in continuously for 3 months.

There are 3 different types of messages: SMS (text), MMS (multimedia) and iMessage. Of these ONLY SMS does not require an Internet connection, as it travels on a voice service subchannel. If you want to get messages without Internet access you must limit yourself to SMS, meaning turn off iMessage. Further, you cannot get MMS (picture) messages if cellular data is turned off, as cellular carriers don't know anything about your WiFi connections. iMessages can use either WiFi or cellular data.

So the answer is you must leave Cellular Data on if you want to receive picture messages from other than iPhones. You must leave either Cellular Data or WiFi on (meaning leave the phone plugged in to power) to receive iMessages. This is not an iPhone limitation; it is the way the wireless world works.

As a separate issue, you need to find out why your battery life is short. In normal use an iPhone should last a minimum of a day between charges; mine lasts 2 days if I let it (I don't; I charge it overnight). But it's important to charge it to 100% every day, and ideally, overnight.

Another of the reasons that I turn off my internet connection overnight is that I get a lot of notifications (Facebook, Whatsapp etc.) that I can safely ignore until the morning, but if an iPhone user tries to message me with something urgent I'm clueless, whereas with any other phone I'd get an SMS straight away. Please don't suggest that I turn off those notifications because they're useful during the day.

You don't have to turn off the notifications, just use Do Not Disturb. Settings>Do Not Disturb. This will allow you to leave your data connection on but not be disturbed by notifications.

No, you won't get notifications but the messages will be there when you wake up. It's not a solution if you want to be awakened at night by your messages.
