How to save your Battery

How to save your battery.

Charging overnight won't degrade really. But charging while using the phone surely will.

Every rechargeable battery has certain number of charge discharge cycles which is specific to its capacity (current output or voltage).

The Basis for charge discharge cycles is the Reversible reaction occurring in the battery.

• (Li+ + e- → ← Li-) ( → Charge ; ← Discharge)

Excessive charging will not help, in the other way it corrodes the electrode enhances the degradation rate of the electrolyte.

So, here's my suggestion - Use your phone from 100% to 5% and only then leave it for charging.

Don't take it to 40% and put it on charge and still keep using it. Battery temperatures can reach around 40°C while you're using your phone with the charger plugged in and that's not good for you battery life.

There are two main types: Lithium ion and Lithium polymer, both are having different chemistries and they are not same. Lithium polymer is light weight and can have more Coulombs* ratings, which means capable of giving more current than lithium ion. Lithium polymer is less likely to die quickly than lithium ion by over charging. But still both lithium ion and lithium polymer can be over charged by leaving charger on.

• 1C = 1A ⋅ 1s

• * The coulomb (unit symbol: C) is the International System of Units (SI) unit of electric charge. It is the charge (symbol: Q or q) transported by a constant current of one ampere (A) in one second (s):

Also turn brightness down, remove from your device unneeded apps and emails, check which apps consume most battery or are get alerts, and in areas of bad reception do a network reset. A lot of battery life especially on iPhones are due to bad upgrade and apps in the background using your resources.

Therefore:

1. Don't use your phone while charging.
2. Leaving it to charge all night is fine, given that you're following the rule above.
3. Charge phone only when it is under 5% capacity
4. Check what is running on your device.

Best practices to maintain laptop and netbook battery life.

You'd think that the best way to keep your laptop's battery from wearing out is to not use it. Right?

Answer: wrong!

As it turns out, batteries are like muscles; they need to be worked out regularly to stay healthy.

Ideally, you should use your laptop unplugged at least once a day, like on a train or bus commute or on the couch in front of the TV.

If you're not going to use it, constantly charging your battery is a very bad idea.

HP recommends on their website that you should take the battery out of your laptop in the following cases:

1. if you're going to leave your laptop plugged in power outlet;
2. if you're putting it in storage for more than two weeks.

Fully discharging the battery is not recommended before storage. Never storage your battery empty, this could kill it for good.

Expiration date.

Should I throw out that old battery? The answer, surprisingly, is "never".

Laptop batteries contain lots of toxic chemicals, and should never end up in landfills. Fortunately, e-stewards.org has a list of environmentally responsible recyclers that will take your old battery with no fuss.

If you can't find one neer you, mail it back to the manufacture.

When is it time to replace your battery, then? Use the free utility apps Becky mentioned, and when they say that your battery can only hold around 25% of its original capacity it's probably time for a new one.

I have a Fujitsu P5020 that I bought about 10 years ago.  My lithium battery now is about 50% of its original capacity.  Most of my friends ended there battery life cycle by 3 years of incorrect usaged, so this is the proof that the above tips do work.

Cheers!
