There's no absolute rules to follow. Most suggest the 20 – 80 rule, which you can definitely follow. You can even do 45 – 75 or others. As long as you understand what's harmful to your battery, you can tailor your charging habit according to your needs and daily routine.
Is it bad to charge your phone multiple times a day? No. Lithium-ion batteries like to be charged in short spurts, so plugging in for five-percent here and 10-percent there is not only fine, but advisable.
When should I charge my phone? The golden rule is to keep your battery topped up somewhere between 30% and 90% most of the time. Top it up when it drops below 50%, but unplug it before it hits 100%. For this reason, you might want to reconsider leaving it plugged in overnight.
Can charging an iPhone too often damage it? No. In fact, according to Apple, keeping your iPhone plugged in as much as possible will improve its battery life.
In actual fact, it's perfectly acceptable to charge your phone three times a day- unless you constantly keep the battery levels near 0% or 100%. Charging your phone three times a day (or even more!) is only safe for your phone's overall battery health if you do not charge it to full capacity each time.
The short answer is no! It is not necessarily bad to charge your phone multiple times per day. In fact, it is better to charge your phone when it reaches a low battery level rather than letting it run all the way to empty.
Android phone manufacturers, including Samsung, say the same. “Do not leave your phone connected to the charger for long periods of time or overnight." Huawei says, "Keeping your battery level as close to the middle (30% to 70%) as possible can effectively prolong the battery life."
Apple recommends, as do many others, that you try to keep an iPhone battery between 30 and 80 percent charged. Topping up to 100 percent isn't optimal, although it won't necessarily damage your battery, but letting it regularly run down to 0 percent can prematurely lead to a battery's demise.
Therefore, we recommend the following: Do not fully charge or fully discharge your device's battery — charge it to around 50%. If you store a device when its battery is fully discharged, the battery could fall into a deep discharge state, which renders it incapable of holding a charge.
The Best Practice, however, is to charge the phone overnight, every night. As it stops automatically at 100% you can't overcharge it doing this.
If your device stopped charging at 80 percent
Your iPhone might get slightly warmer while it charges. To extend the lifespan of your battery, if the battery gets too warm, software might limit charging above 80 percent. Your iPhone will charge again when the temperature drops.
Charging overnight is not a danger to your battery in and of itself. However, temperature is a real concern. One of the most damaging things your battery can experience is extreme heat or extreme cold.
This will reduce battery stability in the long term. SImply avoid charging overnight and instead charge your phone twice a day, once in the morning and once in the evening. This will keep a healthy battery charge lifecycle and hence keep the battery healthy.
“Many people have this habit and don't realize the damage it causes to their battery.” So, the trick: Don't let your phone's battery drain completely to zero, and when charging it, only let it reach about 85 percent and then unplug.
If your phone's battery is draining faster than usual, it either means you're using a lot of energy or your phone is not using energy efficiently. This could mean you're overworking your phone by running too many applications, or something is physically wrong with the phone battery itself.
Avoid Charging and Using Your Phone Simultaneously
However, avoid engaging in a prolonged gaming session when charging your iPhone. Multiplayer games, in particular, tend to cause your iPhone to overheat. Charging your device at the same time will just worsen the issue and affect your iPhone's long-term battery health.
Here are some of the most common ones: There are too many push notifications and alerts draining the battery. There are too many apps running location services. There are too many apps running in the background.
Is it dangerous to use your mobile phone while charging? To put it simply, there's no danger in using your phone while it's charging. It's completely safe to use your phone from a wall outlet or portable charger and does not send electrical waves through your body.
Conclusion. As you can see, leaving your iPhone to charge overnight is not a good idea. Not only does it reduce the lifespan of the battery, but it can also cause the battery to overheat. The battery might catch fire leading to bodily injuries.
To extend the lifespan of your battery, if the battery gets too warm, software might limit charging above 80 percent. Your iPhone will charge again when the temperature drops.
The battery dies quickly
On average, new smartphone batteries should last between five and eight hours on a full charge. Naturally, this depends on various factors, such as use frequency and the number of battery-draining apps.
To extend the lifespan of your battery, if the battery gets too warm, software might limit charging above 80 percent. Your iPhone will charge again when the temperature drops.
