Is it dangerous to charge your smartphone at night? 5 truths about your phone’s battery life

Four major criteria influence this degradation:

• battery age
• The number of charging cycles
• Temperature
• Your uses

In short, your responsibility is also engaged. You may be unknowingly speeding up wear.

Good reflexes

What are the right reflexes to adopt? Discover the 5 essential recommendations below:

1. Never reach 0%
2. Never reach 100%
3. Navigate between 20 and 80%
4. Prioritize short loads
5. Never charge overnight

1. Never reach 0%

A kind of legend Urbaine says it’s a good idea to let the battery drain from time to time. This would make it possible to do a sort of “reset”, resetting the storage capacity.

It’s wrong. On the contrary, aging accelerates noticeably as soon as the charge level falls below 20%.

2. Never reach 100%

This is the most obvious reflex: recharge your smartphone to 100% to benefit from a maximum of hours of autonomy, energy independence.

Alas, what makes sense from a practical point of view is not from a technological point of view. The charging process use more than reason the battery in the 80/100% range.

3. Navigate between 20 and 80%

Taking into account the first two recommendations, it is necessary in an ideal world constantly maintain the charge level between 20% and 80%.

Certainly, it is not obvious. To help you, you can create specific alerts on iPhone relative to the battery level.

4. Favor short loads

To constantly navigate between 20 and 80% of the battery level, the simplest plan is to multiply the short charging sessions.

Ten minutes of charging here and there throughout the day will get you there.

5. Never charge at night

This is certainly very common behavior. Just before going to bed, you plug your smartphone into the electrical outlet. The next morning, the battery level peaks at 100%. Perfect ? Not really.

At night, your charging phone goes into a cycle infernal :

• It reaches 100% battery level
• Charging stops immediately
• It resumes as soon as the level drops to 99%.
• She pauses again. And so on.

This succession of short recharges (from 99 to 100%) is harmful and slowly but surely reduces storage capacity.

Charging your smartphone at night: the other dangers

Charging your phone overnight is dangerous not only for the battery, but also for your security. In the line of sight: the possible overheating of the device. If the latter is placed under the pillow, on the blanket, on the bedspread, on a magazine or even on the mattress, the overheating can start a fire.

The more cautious will put their phone on a small plate.
