How to increase battery life

Follow the guidance for your device in this link --> Batteries - Maximizing Performance - Apple

Note that ALL batteries lose the ability to hold the same charge as new, with every full cycle battery charge. There is no way to stop this. When the battery health on your iPhone reaches 80%, it will then be time to have the battery replaced.

Things to do:

• Don't ever let your battery fully deplete - it is harmful for Lion Batteries
• Do, make sure you use Optimized Battery Charging on your iPhone
• Do, plug your phone in to charge every night when you go to bed
• Don't obsess over your battery as they are consumable parts and wear out, no matter what you do
