How long does your cell phone battery last without charging? Which cell phone has the toughest battery and which one lasts only for a day? Okay I know that this depends on the intensity of phone usage but with "normal" usage (Having 4-5 calls a day, checking your email for few times a day) I have to charge my Huawei U8600 in about 4 days. I'm very satisfied with the performance. I've also heard that Nokia has many models with very good batteries.
