why my camera error and battery drains quickly
I got this phone for free from a friend and i hope i can fix it because i really like it. It has the following problems: When i try to use the camera, the phone does nothing. If i leave it alone it will return to the operator screen after about a minute, if i press any keys after trying to enter camera mode, it'll display "Wait" then enter the camera but with a black screen, then the phone will hang and require removing of the cell phone battery. If i try to use the snapshot key it will just say "Snapshot failed".
Also the phone drains the phone battery really quickly. It barely lasts one day on standby, or 4-5 hours if i'm messing around with the phone (infrared transfers, music). I know both problems started suddenly in April this year, then my friend bought a new phone and this one had been lying unused since then. I don't have a charger so i was charging the battery separated from the phone, and it took around 30 minutes to charge. Now i took the phone apart and soldered a couple wires so i can connect it to a Nokia battery charger. It works, but it takes a long time to charge. When i put it to charge battery voltage was 3.7v (first red line), now it's been over an hour and it's barely up to 4.07v. That makes me think it's the phone not the batttery at fault, the charger has enough power to charge my Nokia 6600 phone battery in an hour.
My friend says it's probably the software at fault, however it looks to me like a hardware error. I'll be getting a serial cable for the phone anyway, any tips how to flash it?And i don't really need the camera. If the camera is at fault, can i just rip it off or will the phone stop working without it?
I left it plugged into my Nokia battery charger overnight because it didn't want to fully charge (my charger has a status led), and now it looks like the charging circuit of the phone blew. The battery is drained and it keeps saying "Insufficient power to charge". Well, it looks like i'll be doing what i should've done in the first place - wire straight to the battery. It's not really the best way to charge a Li-Ion, but during my tests i found out this battery has a very good internal safety circuit, so at least it won't catch fire.
