Yes, all batteries will slowly discharge due to internal leakage current. This cannot be avoided, but modern batteries have far less leakage current than those from several years ago and will hold their charge far longer.
yes it does
Depends how you use it. Normal use required daily charge.
Nothing. Its a normal iPhone thing.
No, it is not normal. iTunes should be recognizing your iPod Touch as an iPod Touch, not an iPhone.
no, iphone apps are only made to work with iphones, not other phones...
No you can text as normal
No you cant the slimmer battery is just too small but the normal battery can fit in both normal and slim PSP!!
pair of good jumper cables (if you are on the road), have another car idle next to you for some time, this should charge the battery enough to be able to go home (if you dont live far from where you broke down. Switch off headlights, radio anything that you dont have to use. As this all drains power (including hazard lights). When you get home, get an approved battery charger and charge your battery on normal charge (you get a choice between rapid and normal). And get your charging system checked asap!
Yes. The battery charger exerts more electricity than the batteries have itself. If you touch it and it burns your hand. IMMEDIATELY turn it off.
Under normal circumstances, if the battery is low enough that the console switches itself off, the battery's remaining charge is used to maintain the clock time and other details you've entered. However this charge too will eventually run out, and the date/time will be lost. So you should keep it charged.
iPhone 3GS uses a normal SIM Card, iPhone 4 uses a Micro SIM Card. If you buy an iPhone 4 you have to choose an operator which sells/supports Micro SIMs. Note that depending where the iPhone is brought (Apple, Verizon, O2) it might be locked to a certain operator.
A car battery cannot overcharge itself under normal circumstances, as it relies on the vehicle's charging system to regulate the charge. However, if the charging system malfunctions or the voltage regulator fails, the battery can receive too much voltage, leading to overcharging. This can cause damage to the battery, including overheating, swelling, or leaking. Regular maintenance and monitoring of the charging system can help prevent such issues.
