You still using phone with NIMH or NiCD batteries?First time charge need 6-8 hrs.
This not only applies to iPhones but other phones too.
The last I read, lithium batteries no need to "over charge". But should not let it drop till zero before you charge again. Another thing lithium batteries don't like is heat so the battery will last longer if it is not expose to too much heat.
Cold temps also not good for lipos. Reduce battery life.Looks like what i have been doing is right. i always leave my phone is in the fridge to ensure the battery lasts long.
Then condensation forms internally when you take it out, gg.Looks like what i have been doing is right. i always leave my phone is in the fridge to ensure the battery lasts long.
