I bought a Nokia 5310 the fancy and jazzy phone, which is making all news for musicXpress. Not to exaggerate, I charge the battery for about 4-5 hours and the battery lasts only for 8-10 hours after the charge. Horrible.
This is not worth the money 10,690 that I paid for!
Solution of your complaint
Replace the battery which can last for days or replace phone, who wants it!
