Can you safely charge the Galaxy S3 with a Note 2 charger?

Posted Dec 31, 2012 at 4:21 pm in Threads > Smartphones & Tablets

The Note 2′s charger output is 2.1a while the S3 (IIRC) is 1.2A (or something above 1.0A).

Can you safely charge the S3 with the Note 2 charger? I don’t want to fry my phone with it but it would be nice to get it to charge faster.

Yes it will work fine. I usually use different chargers all the time and haven’t had any problems

I wouldn’t make a habit of it, but it won’t really hurt anything. LiPo batteries tend to last longer if you charge them a bit slower. I use a 550ma or 850ma charger for my HTC phone instead of the 1A that it came with.

I recently lost my charger to my Note 2 and was using my kindle charger. The phone was plugged and the battery life was dwindling as I was using it rather than charge it. My HTC evo charger charges it faster and I just used a galaxy s3 and it worked great. Still not as fast as a note 2 but charged it to 50% in about 2 hours.

They’ll both work fine. Theoretically, charging the S3 with a 2.1A charger could shorten the number of recharge cycles in the battery, but generally it’s fairly insignificant. By the time you reach anywhere near that point, you’ll probably have replaced the phone anyway.

Thanks guys. I read about the (possibility of) shortening your battery’s life span but it’s nice to use to get some juice in there quick.

  Dont use higher rated chargers on the phone except the one it came with u ruined the phone…
  
  this is the exact same thing which happened to me when i was using hTC windows phone, i used a nokia lumia 610 charger which is 1.5A and after a few charges the phone started to behave erratically with random reboots, crashes
  
  the problem here is that your phone has many components like sim card reader, antenna and other stuff, although the battery will charge with 2A , it is safe to do so but the extra current will fry the other components which ar enot designed to take in the heat generated by a higher current

  I hope so,I’m 30mons into an hour YouTube show,that is charging.
  
  It is perfectly safe,It will just charge that much slower.
  
  If your using satnav on a long drive it needs to be plugged in.usually the USB charge will be enough for you phone not to lose power, but usually won’t gain any either.satnav is a big power user.
