Does using a phone while it is charging really damage the battery?
While the phone is being charged the charger supplies necessary current to charge our phone battery.lets make one thing clear,while you use a device(even if its screen is on) the phone draws its power from the battery only.when the device is used while the battery is charging it actually means that the charging current from charger is divided and is shared with the battery and our device,thus the battery rests in equilibrium state of charging slowly.This causes the battery to be charged slower.the problem with most chargers is they don’t supply enough current while the phone running on battery its power draw might vary depending upon use case like signal strength, data connection on etc.These spikes of power drawn cannot be supplied by chargers so the battery should supply which makes the constant slow charge state unstable,this causes the battery to discharge and then charged again.note that cheaper chargers which might not be able to handle high currents might get damaged.Battery life time is determined by many factors out of which charge cycle plays important role,when a battery is charged and discharged completely, it is called 1 charge cycle .In the above case the battery undergoes lots of partial charge cycles which in theory shouldn’t affect normal phone’s batteries since they are Li ion based.If your phone for some reason is Ni-Cd battery bad day for you as these batteries have some memory effect and thus partial charging and discharging might cause serious battery life degradation.its not over!!!!!!!!!!!1The other main enemy out there is heatwhile you use your phone normally it heats,this is due to many reasons but they do produce heat normally.Your batter produce heat while charging (why they produce is another topic ).if there are two heat sources your phonemight heat up badly and this can reduce your battery life.In Summary*its not proven that using phone while charging is dangerous for battery.*you can use your phone while charging if your device is within temperature limits*using good quality charges is good for battery and you overall.ps:I am new to quora and might not meet the standards so please forgive me.the articles i considered for this questions are:How to Prolong Lithium-based BatteriesBattery charging tips and tricks for prolonged lifeand some common science :)
Side effects of overusing mobile data tethering?
What's the side effects of using your phone for internet gateway? I'm pretty aware of the data usage limits. I'm more concerned about the heating on the phone and battery. What could possible go wrong if I overuse my phone as Internet gateway? (I'm talking about 5,6 hours of heavy internet usage)
Is it safe to use a phone while it is being charged by a portable charger? I own an HTC and was told by a mobile technician to use an HTC charger only. An HTC powerbank is not available in my city. Can I use a Sony portable charger?
It’s best that you don’t use your cellphone while it’s charging because the battery starts draining out, which triggers its heating process. At the same time, while your cell phone is getting charged in the background, it adds to the heating process and the battery becomes hot. This can have ill effects on the battery life, and if the battery is faulty or not a branded one then there is a good possibility of extreme heating issues, which may lead to battery explosion. So, it’s better if you do not use your cellphone while charging to be on the safe side. Instead, use compatible charging accessories like portable USB chargers, wall chargers, or car chargers to avoid any kind of damage.
Accidentally leaving your iphone charging over night?
I had a samsung galaxy s3 and the battery was fine up until i started leaving it charged overnight. Then i started experiencing many battery problems like my phone would charge very slowly but drain out very quickly. I got many new battery packs but the same problem kept occurring. I learned from different mobile repair shops that i shouldnt keep it charging overnight cause it screws up the battery. I just recently switched to the new iphone 6 and the battery life is amazing but i left it charging overnight by accident twice. I dont know if its me being paranoid or im just using the phone too much but i feel like my battery isnt doing as well as when i first got it (i got it about four weeks ago). So does leaving your phone charge overnight really screw up the battery life?
Is it bad to charge your phone over night?
Thanks for the A2A.As Liang-Hai Sie mentioned, you don't have to worry about the memory effect that used to occur in older nickel based batteries. Also, today's smart devices are pretty smart when it comes to charging. You may notice that when charging it takes a lot longer for the last 10%-15% of your device to charge than it does the first 10-15%. This is due to the device "trickle charging" the last percentages. This is similar to how the device handles being plugged in when at 100%. I'm pretty sure the device will only take as much power as it needs to stay at 100% when plugged in, which isn't much at all.Also, if you are worried about wasting electricity, here is how much it costs to charge and iPad for 1 year: How much energy does it take to power those iPads? The answer is $1.36 by the way. Granted that is if you charge it every other day. So, keep that in mind, but even if you charged it every day it would only double so not a big deal.And if you are really interested in optimizing your battery life, you can check out this guide here -> How To Take Care of Your Smartphone Battery the Right Way. However, again, don't go crazy and don't worry too much as the gains are minimal.
