The most basic one is charge whenever you want to, for a long as you want to. There's no reason to let the device drain completely before charging (in fact, it's a bad idea to do that on a regular basis), and there's no need to wait until it reaches 100% before removing it from the power source.
Is it bad to charge my phone to 100 percent? For optimized battery life, your phone should never go below 20 percent or never above 80 percent. It may put your mind at ease when your smartphone's battery reads 100 percent charge, but it's actually not ideal for the battery.
Use power-saving modes to increase time between charges.
Both Androids and iPhones have special battery-conservation modes that turn off background apps, decrease processing power, dim the screen, and disable other services that can drain your battery quickly.
It's not harmful. The battery is designed to be charged to 100%. If if wasn't, they wouldn't call it 100%. The battery management system in the phone is designed to prevent the battery from overcharging, which would cause damage.
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.
What percentage should I charge the battery to? For regular use, we recommend keeping your car set within the 'Daily' range bracket, up to approximately 90%. Charging up to 100% is best saved for when you are preparing for a longer trip. You can adjust how full the battery charges from the charge settings menu.
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 you do fill your battery completely, don't leave the device plugged in; doing so constantly can cause your electronics to age faster in the long run.
If you charge your iPhone overnight for eight or so hours, that stresses it more. Even with optimized charging, the battery is still taxed after it reaches 100 percent, so by leaving it charging overnight when it doesn't need it, you're putting undue strain on the battery.
Charging My iPhone Overnight Will Overload the Battery: FALSE. The one thing all the experts agree upon is that smartphones are smart enough that they do not let an overload happen. Extra protection chips inside make sure that can't happen in a tablet or smartphone or even a laptop.
2. Unplug your iPhone once it's charged: As mentioned earlier, iPhones have a mechanism that prevents overcharging. But if you keep it plugged in too long, it can cause the battery to age.
It's especially important to avoid exposing your device to ambient temperatures higher than 35° C (95° F), which can permanently damage battery capacity. That is, your battery won't power your device as long on a given charge. Charging the device in high ambient temperatures can damage it further.
It's best to charge it when it goes below 20%, primarily to avoid the risk of it going to zero when you don't have a charger available, and to prevent unexpected shutdowns when you might need the phone.
Shomes recommends charging your iPhone as it needs it. If you go to sleep and it has a 40 or 50 percent charge, leave it. Then charge it some time during the next day when it gets into the red. That way, the battery won't be stressed, and its health will last way longer than it will when overnight charging.
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."
To turn off the feature, go to Settings > Battery > Battery Health & Charging and turn off Optimized Battery Charging.
Hello~ Yes you should..it is better to do so. Your iPhone cannot over charge and automatic updates can occur overnight while charging and connected to WiFi so you are ready to go with a fully charged battery everyday.
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.
If you leave your phone on the power adapter for long enough, the battery will drain a little bit to 99 percent instead of 100 percent. Then, the charger will kick in to take your phone back up to 100 percent before it shuts off again.
Having said that, experts recommend charging the battery from zero to 100-percent about once a month. This will reset your phone, and help it run quicker as well.
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.
On average, a cell phone battery should last between two and three years. After that, it will likely begin to have a negative impact on your cell phone's performance. Here are a few common symptoms of a dying cell phone battery: Needing to charge your phone multiple times in one day.
No matter what you do, your iPhone® battery has a limited shelf life. As it ages, the battery slows—so a full charge won't last as long. Most batteries are good for at least 2 to 3 years, often longer, but how do you know when to replace your iPhone battery? At Asurion, we help millions of people maximize their tech.
OVERCHARGING
Never let your battery sit at 100% charge. Generally speaking, lithium-ion batteries do best when they operate in the 30%-80% charge range. Although it may take some extra planning, prolonging the time spent within that middle range may extend the life of your battery.
