How to unload the battery

[quote="Freddie666"]Just found a great way to unload the 7650's battery (which one should do sometimes to make it last longer): I use Breakthru (btw a nice game) for this .. 😊 .. If you pause it and send it to background, it drains the battery in 2 hours - by running the cpu and keeping the light on[/quote]

The 7650 has got a Li-Ion battery which you should NOT unload completely! It stresses the battery and shortens its span of life!
NiCD and NiMH batteries are the ones that should be fully unloaded sometimes.

really??
(i dident know that) 😞
so your saying I shouldnt let the battery go completely to ZERO? and the phone turns off by it self then
then when should i charge the battery??
is it fine when i get the first message that battery low then Charge it
do u think that will also decrease the battery's life??
could you please let me know

Whenever you feel like. 😃
I have the charger plugged in whenever im at home.
Its the wonder of the Li-Ion battery 😃

Yes, really! Li-Ion batteries should not run empty, it shortens their life. An advantage of them is though, that you can load them whenever you like. They have got no memory effect like the Ni-type batteries have. I have my phone connected to the charger whenever the charger is in range. The Li-Ion battery of my previous phone is more than 2 years old now and it hasn't lost any capacity!

one question
does the life decrease of the battery when i get the message that battery is low or does it only effect when the battery runs empty?

I have read somewhere (please don't ask me where that was, I don't know anymore...) that the fill level of the battery should not drop below a certain point. Under that specific level the battery is put under stress. The more empty the battery is, the more stress it has. Any electrical engineering technician here, who can explain this better?

As far as I know, Li-Ion batteries should be emptied all 5 -10 cycles, but not - dont know the english word - totally emptied. But the phone turns off himself long before the battery is really empty, so nothing can happen.

so I should charge it as often as i can right?? ^_^

Right! The advantage of it is that you have always got a full battery 😉

So it doesn't matter if the battery is half full or 3/4 full when we put it on charge...

But what if you take it off charge before its totally full... does this affect the capacity?

Is there in fact anything that affects the capacity of the battery then?

Right!

[quote="evobit"]But what if you take it off charge before its totally full... does this affect the capacity?[/quote]

No. That should not affect the capacity in any way.

[quote="evobit"]Is there in fact anything that affects the capacity of the battery then?[/quote]

Nothing. If you don't let it run completely or nearly empty too often....
And the battery has got of course some natural aging, but there's nothing you could do about this 😉

Thanks to all, and especially to tiger42! I learned a lot about these batteries!!! 😃

Yeah! I want to thank too! Now I know more! 😃

I just want to add that,like guest said,when the battery is brand new,it should go trough couple (3 to 4 will be enough) of empty-recharge cycles in order to achieve full battery capacity.

Just clarifying, does this mean you cannot overcharge these types of batteries??

The charging of Li-Ion batteries is a very complicated process. You have to apply different voltages at different times and different battery temperatures to it (yes, your battery has got a built in thermometer!)
This process is completely controlled by your phone (not by the charger as many people think...), and the phone of course prevents the battery from beeing overcharged. If the battery is full, the phone switches to "conservation loading" (don't know if this is the correct english word), which just keeps the battery full, but not really charges it any further. So only if the charging circuit in your phone is defect, it might be possible to overcharge the battery. Btw this is also the case for older phones which only use NiMH batteries.
I hope I have expresed myself clearly?!

Wait a minute? I didn't get the battery part!

Merlin,if you are refering to me,i was joking 😃

No GhostDog, I wasn't referring to you, or anyone else; just simply providing a possibly useful faq to anyone who may be interested to know more about Li-ion batteries 8)

:angel: :angel: :angel: Great Info Merlin :angel: :angel: :angel:
😃 😃 We all thank you 😃 😃

sorry to post jump but, anyone know if there is some kinda battery monitoring tool for the 7650? if not somebody interested in writing one, you know time the battery has left in hours (estimate) time last charged, percentage used etc.

not sure if it would be possible but would be quite handy.
