[URGENT] Battery-related questions for a Liquid S2

Hello all,

I've bought an Acer Liquid S2 phone a couple of days ago and I have some questions.

I've failed to format the battery. I didn't leave it charging for 8 hours for the first time, as I've just read in the second manual. I charged it 2 times already and the 3rd charge is in progress. My first question is:

Should I leave it to charge for 8 hours as an attempt to format the battery or should I just unplug it after it's done?

Also, in the first manual, it says that overcharging the battery can damage it.

Doesn't that mean that formatting it for 8 hours will damage it?

Please reply as soon as possible. Thanks in advance.

Hi di57inct,

No problem at all about 8 hours charge.

You can "reset" the battery charge sensor (not really a reset but more a calibrate), going around 15% of battery life then power OFF your S2 and connect it to the charger.

wait until 100% charge, disconnect the charger and power ON your device.

that's all

remember that modern batteries don't need to be fully discharged (don't do it!!!), since they doesn't have "memory" charge issue.

@IronFly hi and thanks for the quick reply.

It's just that the manuals clearly state to format the battery for 8 hours and for the first 3 times to fully discharge and recharge the battery to get to its maximum efficiency. Both things are the exact opposite of what you just mentioned...

So as I previously asked, should I leave it now to charge for 8 hours or should i just unplug it when it's done?

Also, should I do that calibrating thing for the next recharging?

Thank you once again.

nope it's not opposite, simply they tell you to charge 8 hours, just to sure you fully charge at 100%.

if you miss this the first 3-4 times, the battery can suffer and battery sensor fail to calibrate correctly.

Lithium-Ion – Li-ion batteries are the newer type of battery that are found it most newer cell phones (most definitely most, if not all, smartphones use Li-ion and many “dumbphones” use them too now). Li-ion can be thought of as “smarter” than NiCad batteries; Li-ion batteries don’t suffer from the “memory effect” and thus don’t need to be conditioned like NiCad batteries.
Rather, to condition a new Li-ion battery, fully charge it; it should be allowed to charge for 7-8 hours on the first, initial charge. In other words, when you get your new cell phone – and it has a Li-ion battery – allow it to charge for 7-8 hours even if the cell phone claims to be fully charged. (It is preferable to use outlet charger vs car charger or USB charging via computer because of the voltage difference.) After that, there is no reconditioning necessary for Li-ion batteries since they don’t suffer from the “memory effect”. However, be sure to avoid fully draining/discharging the Li-ion battery as much as possible; every time a Li-ion battery is fully discharged, it loses battery power and life. (That doesn’t mean your battery will die if it is ever fully discharged; it means it is best to avoid fully discharging when possible.) Try to recharge Li-ion batteries when they are at 15-25%. Similarly, avoid heat as much as possible and when (if) storing Li-ion batteries, store them not at full charge.

Update: The only time you should ever intentionally fully discharge a Li-ion battery is if your phone is not properly reading the battery. In other words, if you go from 100% -> 90% in ten minutes but go from 90% -> 80% in one hour with the same amount of usage, that means your phone is not reading the battery output evenly. If this is the case, then fully discharging your battery once and then recharging it can fix the issue of your phone not reading the battery properly. Take note, however, this full discharge/recharge won’t increase your battery life — it will only ensure your phone reads the battery properly.

People often confuse Li-ion and NiCad batteries and try to condition Li-ion batteries by charging/discharging them 4-6 times. Trying to condition a Li-ion battery like it is a NiCad battery (i.e. charging/discharging the Li-ion battery 4-6 times) hurts the Li-ion battery more than helps it. So, be sure to condition your new cell phone’s battery, but be sure to condition it properly. Otherwise, you may be doing more harm than good. If you are not sure what type of battery you have, read the labels on the battery – they will always say whether the battery is Lithium-ion or Nickel-cadmium. Good luck and may we all have long lasting batteries =D.

Well, I'm sure I've charged it 100% every time, BUT I've plugged it in the computer twice(both times while it still had battery, once while it was shut down) and it automatically starts charging when doing so.

Of course, I didn't let it fill because I had it connected for just a few minutes so I could get my files from it to the computer. Could that be a problem?
