Best Battery-Charging Routine

[Guest Saracen]

Have a look at this link:

http://www.batteryuniversity.com/

Lots of info on rechargable batteries of different types and how best to cycle (charge) them to attain longest life.

Here's what they say about Lithium-based batteries:

- Avoid frequent full discharges because this puts additional strain on the battery. Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory. (In this respect, lithium-ion differs from nickel-based batteries.)

Short battery life in a laptop is mainly caused by heat rather than charge/discharge patterns.

- Although memory-free, apply a deliberate full discharge once every 30 charges to calibrate batteries with fuel gauge. Running down the battery in the equipment does this. If ignored, the fuel gauge will become increasingly less accurate. The battery life will not be affected.

- Keep the lithium-ion battery cool. Avoid a hot car. For prolonged storage, keep the battery at a 40% charge level.

And here's a table that tells you what to do with different battery types. Apparently Li-Polymer is to be treated like Li-Ion:

Hope this is useful!

The information above would be sensible if it took into account the fact that almost fully discharging a Li-Ion battrey repeatadly, or actually fully discharging a Li-Ion battery will destroy the battery.

The battery has inbuilt circuity which requlates the charging and discharging of the battery. This circuit uses very little power, but if the power does completly drain the ability to manage the charging and discharging of the battery disappears with it. The Battery management will attempt to cut off the device when it gets to a set level, however if you were to fool the battery into continuing to drain...

This is often the fault with spv's that will not reach the bootloader.

The battery management can be fooled, if for instance you rapidly insert and remove the charger.

Fully discharging the battery does damage your phone - be warned!

Yep, it mentions that in the site. The main thing I wanted to bring to people's attention is that you don't need to let your battery go flat before recharging and memory isn't an issue. It seems lots of people still spread the "advice" of years gone by about batteries. That's all.

It does say in MoDaCo's FAQ full discharges arent required, and will damage the phone, but the FAQ is outdated and not many people read it :/

Anyways all will be cool when my sites done hopefully

on my SPV E100 i charge my battery pretty often because i cant do without my phone (i feel lost without it)

anyway i forgot to charge up my battery one night and so in work the battery level went bellow 50% and my phone turned off as though the battery was empty so i turned it back on and within seconds the phone was off again without shutting down

thought it was the phone dammaged untill i plugged in the charger.

i work in a hot environment and the phone is in my pocket... using the thermomitor utility my phone is at around 30 digrees C at all times, also when im in work i cant get a signal in some places which also uses more battery life

So we know how we should discharge it, but what about the charge?

What I mean is that, let's say a battery goes to 40%, is it better to charge it to 100%, or is it OK to charge to for example, 78%, or, does it not make any difference either way?

[Guest squall]

Full charge is preferrable but you can get away with non complete charges.

I wouldnt do it everytime, as the battery is only designed to last for so many charges
