Apple claims that properly maintained iPhone battery will keep up to 80% of its original capacity even at 400 full charge and discharge cycles. So, the question is how to maintain and charge iPhone battery to prolong its life? Following are a few simple iPhone tips, first five are the most important:
-
- Make sure that you fully recharge iPhone / iPhone 4 / iPod Touch battery at least once per month (fully recharge means charging the battery to 100% and then completely running it down).
- Don't drop the battery charge to low.Battery cell has its own safe-voltage-limit (~ 3 V). iPhone battery is vulnerable to damage if the low voltage limit is crossed.
- To prevent failure, never store the battery fully discharged. Apply some charge before storage, and then charge fully before use..
- When possible avoid frequent full discharges. Instead, charge the battery more often. There is no concern of battery's memory when applying unscheduled charges.
- Avoid iPhone / iPhone 4 / iPod Touch from both overheating (> 35° C )and undercooling (< 0° C). The optimal temperature for IPhone is 22° C. The elevated temperatures hasten permanent capacity loss for iPhone battery.
- Free iPhone / iPhone 4 / iPod Touchfrom its leather or any other case when charging the battery. Those cases prevent adequate ventilation, and cause extra temperature rise while charging.
