A recent excellent post from Android Authority about battery myths was enlightening -because I believed in 3 of them. I bet most of us will believe in all or most of these – but they are all myths
- Plugging in your charger into phone all night long damages the phone: not true. Many years back, batteries did over heat and get damaged. But advances in battery science (is there such a thing?) means that batteries are much better at managing ‘overcharging’. As per Android Authority, the only slight risk is if you use a battery case which does not allow heat from charging dissipate appropriately. So ideally, remove the case or buy one which does not trap heat.
- Completely discharge your battery before recharging: Nopes, not needed. Again, older nickel batteries would not remember what their full charge level was – so it was important to discharge them completely before re-charging. No longer required with new lithium ion batteries.
- Always use ‘official’ chargers: Just a marketing ploy to increase revenues. You can use any charger as long as it has the right ports.
- Don’t use your phone while charging: Given the number of people I see who are holding their phones in one hand and a portable charger in another – I don’t think a lot of people believe this. Nevertheless, it’s not true – use away!
- Kill apps running in background: I think this is the most believed myth. The biggest battery drainer is your screen – so set it to dim in a minute or so and you will be fine. Apple recently confirmed this on twitter. As a matter of fact, if you spend time closing apps and then relaunching them, it drains your battery more than simply letting them run in background.
- Disabling Bluetooth and Wifi will save battery: I wouldn’t call this a complete myth – Android Authority confirms that while this does save battery, its not a lot – 30 min a day at most.
So quit worrying about battery life, just switch off the display when not using the phone!
