Battery mystery in Google Nexus S
Ever since Day 1 with Google Nexus S, I never have the phone fully charged at 100% – the phone always claimed to be fully charged at 94%-97%, and charging the device overnight doesn’t help. Faulty battery?
Nope. Luckily my 1500mAh Lithium-ion battery in Google Nexus S seems to be pretty normal after I did some extensive studies on this phenomena. Not too sure it will occurs in all other Android devices, but apparently fully charged at the battery life of less than 100% in Google Nexus S is not something need to be worried.
In Byron G’s study, he did an extensive study on the charging and discharging conditions on his HTC Droid Incredible and figure out the reason of inconsistent battery drains, especially during a full charge. It’s a lengthy article, which is a pretty interesting one, so if you have about 15 minutes to digest it, do check it out.
