Question

Is a 100% full charge good or bad?

Community Answer

It's not optimal, but it's not as damaging as letting the battery go below a 30% charge. Keeping it between 80% and 30% is ideal.

Question

My phone runs through a full battery charge in 50 minutes. What should I do?

Community Answer

This is generally a sign that your battery needs replacement. If you know your battery is healthy, but you're still running through a charge in 50 minutes, you may have downloaded an ill-behaved app that is burning through your battery. On Android you can go to Settings>General>Battery>Battery Usage to see what app is consuming your battery and uninstall it if it is unneeded. If you can't identify the culprit, consider doing a backup and reset.

Question

Why is my battery not fully charging?

Community Answer

It could be that the contacts on the battery are dirty or are fouled. Get a clean Q-Tip and gently rub the contact until it appears clean. Do not use gasoline or any cleaning fluid!

Question

How long does it take for the battery to become overcharged?

Community Answer

Avoid charging frequently. Charge when the battery is below 20% and try to charge it until it is full. Don't charge if the voltage is not normal or is fluctuating.

Question

Can I charge my phone with the power on?

Community Answer

You can, but it may cause your lithium battery to heat up too much, so it's not recommended.

Question

If I store my electric bike in the cold weather, will it ruin the battery?

Community Answer

It's probably not great for it but the best place for information would be the manufacturer's recommendation, which is usually in the instruction manual, in the box, or on their website. It seems that some batteries are designed for being used in the middle of winter and some are very picky about their operating temperature.

Question

Will my phone with an ion battery charge in 6 hours?

Danielle Husband

Community Answer

Your phone should charge in less than 6 hours. If it isn't charging within 6 hours, the battery may be damaged.

Question

If I interrupt the first charge of a lithium battery before it reaches 100%, does it damage the battery?

Danielle Husband

Community Answer

It shouldn't damage the battery. While it's true that old batteries used to get damaged if you interrupted their charge, lithium batteries typically work better if you don't charge them to 100% each time.

Question

How long will a lithium battery last if it's in storage?

Danielle Husband

Community Answer

This depends on the battery and how long you've been using it. For best results, charge your battery up to 50% and check it every 2-3 months. Take your battery out of storage at least once every 6 months to use it. Otherwise, it will gradually die.

Question

What would cause my lithium ion laptop battery to die only half an hour after being fully charged?

Danielle Husband

Community Answer

It sounds like your battery is near the end of its life cycle. It's possible that it's old, but it may also be damaged. You likely need to get a replacement battery.
