I think this is probably a bit basic, but I've tried googling and have posted elsewhere.
The question is vey simple. I've recently bought a new smartphone, with a standard lithium battery. Every other lithium battery device I have had charges in stages. They go quite quickly up to 80%, and then really slowly for the last 20%. This new one, however, charges in a completely linear fashion. Every 1% of charge takes about 1 min 30 seconds, all the way from low charge to 100%.
I've read that the stepped charging pattern, which I've always seen before, is for safety and to protect the battery. Is the way my new phone charges normal these days, or could there be something wrong?
