Enhancing Your Battery Life
As phones have got bigger, brighter and more sophisticated, so their battery lives seem to have reverted to the stone age. Any decent one will of course still have sufficient to make and receive calls all day, but will it leave enough to also do the things you actually bought a smartphone for? A couple of hours browsing in the afternoon, maybe some handheld GPS navigation around town, and suddenly it’s looking like you may not make it home to your charger in time.
What’s to be done? Well Android does present a lot of power-saving options, but it’s not at all clear to the user just how much these will save or what functionality they sacrifice.
OK, some are no-brainers. You will extend battery life very significantly if you don’t turn on Wi-Fi, Bluetooth and GPS until you need to connect to a network, link your phone to some other device, or find out where you are, respectively. (And remember to turn them off again after!) It’s worth mentioning too though that Wi-Fi needs less power than a 3G connection, so use it to go online when you have the choice. Of course, that will also save you data charges.
That huge vivid screen drinks power like a power alkie falling off the power wagon. If you’re not trying to impress anyone with its shininess just now, set the brightness as low as you find usable. (Settings > Display > Brightness; Your phone’s automatic brightness setting, which allows it to adjust to the ambient light, may be the best compromise.) While you’re here in Display Settings, you can adjust the screen timeout – the length of time it stays lit after you stop touching it – to be as short as you can tolerate.
Those are the biggies; after that it’s all fiddling with minor adjustments that might or might not make a noticeable difference. What would be really nice to find is some hidden setting that dramatically improves battery life, a sort of magic button if you will. Not too much to ask, is it?
Well no it’s not. There is one simple thing you can do, and it will save you buttloads of electricity¹. You can turn off Packet Data.
Packet data is what’s more loosely referred to as “3G” – Internet over the mobile network. Your Android phone, by default, keeps a data connection going all the time. This means you can constantly receive things like emails, calls over Skype and other VoIP systems, MMS messages, and fresh new adverts for your ad-supported apps. Nice stuff – well mostly – but not exactly necessary. Especially not when you consider that the time you’re spending online without really meaning to is deducted directly from the time you can be online when you want. Simply maintaining that data connection is eating your power, even when nothing is being transferred.
One problem: Android is kinda designed around the always-on data connection, they don’t really mean you to turn it on and off easily. So the option is a little buried, under Settings > Wireless and network > Mobile networks. There you check and uncheck “Use packet data” depending on whether you want mobile Internet access right now. Four clicks down – pretty irritating for something you might want to change several times in one day.
But fear not – there is of course an app for that. Or to be more precise, a widget – a simple button you can stick on your home screen to turn packet data on and off handily. There are a great number to choose from on
the Android Market Google Play in fact; some though are ugly-looking, some have ads, some other features that you may or may not want. One I found that seems to work just fine, looks nice and is both free and ad-free is called Data Switch. I can’t promise this one will work flawlessly for you (try restarting your phone if it doesn’t seem to at first), but it seems to work perfectly on the Galaxy Note.
While the Note’s battery is very reasonable by smartphone standards, this could make all the difference between worrying if it will last, and being relaxed about it. So if you really want to Skype me, call me first to let me know OK?
