Tips for Battery Treatment: No more Half-Truths

Applies to current Devices with Lithium-Ion Batteries

  • new batteries may be used immediately without charging
    (usually delivered ex works with around 70% charge)
  • Heat is the biggest enemy of lithium-ion batteries
  • each complete charging cycle shortens the service life
  • recharging is better than discharging completely (if possible, charge at 30% at the latest)
  • deep discharge shortens the service life considerably, possible immediate defect
  • the charging electronics switch off the charge at 100%
  • there is no memory effect
  • when using a power adapter from the manufacturer designed for this purpose, the system switches to power supply from the power adapter at 100% battery charge

Battery Performance – Theory and Practice

Prolonged use of the mobile phone (maintaining the address book, sending text messages, navigation, playing games, etc.) requires a lot of energy because the display and power-hungry backlight (LCD) are switched on for a long time. If GPS is used frequently, the battery is drained very quickly. WLAN no longer consumes as much energy in modern smartphones as it did in earlier models and whether Bluetooth is switched on no longer plays a role in today's devices.

Manufacturer Information on Standby Times is pure Theory

The manufacturer's specification for the maximum standby time is determined under non-practical laboratory conditions:
The device is lying unused in a place with the best reception.
Bluetooth, GPS, WLAN and display are switched off!
Only system applications required for operation are running.
This means that fantastic values of over 300 h are possible!

In practice, the specified maximum talk time can only be achieved directly after a full battery charge, even with the best reception.
