Phone can become less playful and more serious by switching off the animations. You can also select one of three graphic appearances directly in a profile (more about this later). Performance
Siemens C35 uses a NiMH 500 mAh on 3.6 V. I admit the phone battery duration was not very fascinating. The firm declares 50-180 hours stand-by or 90-300 minutes talktime. But in practice the Siemens C35 remained close to the lower end of the range. - It would last over two days when practically unused. But with extended usage of SMS (hence display illumination) and calling, the battery easily wears out in one day. So, it necessarily loses some points here!
Practical tip proved from the previous models. Switch off the automatic network selection, cell broadcast (which is useless for us anyway) and display illumination. How do you read data on your phone without illumination? You press and hold the red power button. Menu and Phone Operating
The menu style matches the Siemens S25 trend - you can scroll through the menu using the keys bellow the display. The keys are divided in half, which means the left and right sides may have a different meaning; this will prove in WAP. Menu items are in some cases animated. The top level menu items are as follows: SIM Toolkit menu (if there is a toolkit SIM card), Internet (this is the first menu item), Work and Leisure, Messages, Phone books, Profiles, Ring tones, Time/Cost, Diverting, Phone settings, Useful tips (basically Help). You will basically have no troubles with the menu. And if it seems too long to you can reduce the menu to the important functions, according to Siemens, using the Menu mode. No personalization of this 'abbreviated' menu is possible. Pity! The more expensive Motorolas have dealt with this nicely. You can use shortcut keys for moving through the menu.
Phone operating is smooth and I would say you get accustomed to it quickly. One key is reserved for phone book access; it can also be used when typing SMS for entering the recipient's name. . Scrolling down the SMS messages menu, you can see how many messages are stored in individual folders. As you type, help is displayed on the screen which letters and numbers are still available for the key you are currently using. Making Calls and Phone Book
C35 learned from its older brothers. You can operate a classical phone book as well as a 100-entry memory, which will certainly come in handy. You can also create so called red phone book (sometimes called - the VIP directory/list) to rearrange and store important phone numbers.
