3310 keeps dying during conversation even when just charged

[Tailsy]

Hi

Just wondering if anyone can help me here please.

I charge my mobile and then go in a conversation and after a short while the phone/battery dies on me. So I thought maybe I need a new battery, so I stuck a new one in and I get the same problem.

Any ideas anyone please? The phone is a 3310.

Thanks.

yup its the battery or matbe the internal circuitry of the battery inside the phone.

i have the same problems months ago. even sending messages would turn my phone off. and i flashed it several times with original flash files and still it turns off.

i bought a new ORIGINAL NOKIA BATTERY. take note that its original. fake batteries are now availble in the market. and now my 3310 is as good as new!

hi thanks for the reply, so you reckon it could be the battery even thou i put a new one in and it still did the same stuff?

Hello :)

I have already twice been confronted with a similar problem. The respective 3310 and another 3315 would charge and stay standby/idle for an eternity, yet when being on a call, within 2 minutes they would simply turn off. Re-flashing did not change a thing, BU -

other batteries ALSO didn't change a thing! I have a selection of batteries here, most of them original, NiMH and Li-Ion ones, very old and fairly new ones. None of them made the phones behave any different, even a BLB-2 scotch-taped into it didn't change anything... all of them charge normally, keep the phone idle and when on a call, it will shut down no later than two minutes in the conversation.

I brought the phones (it were a 3310 and a 3315, both from the same colleague of mine, with a few months between the first and the second case) to a repair shop and in both cases the same chip on the PCB had to be replaced. Each fix costed me 250 Baht only (seems to be a quite cheap chip, that one, that is just 6.25 us$) and both phones worked happily ever after with just about any battery :)

Kind regards.....

Hi mates,

the most probable cause of problem is the RF Power Amplifier. It consumes a lot of power when transmitting. Idle period do not transmit continuously, only burst for maintenance check and location verification.

hope it helps...

Yep, PA! I have a heap of 33xx with this, the PA is leaking, so when you are on a call and the PA is fully working it will "leak" a heap of power very quickly! Needs to be repaired or replaced!

How do you replace the PA? I'm guessing you need a bit of SMD soldering skills for this?
