What is battery? It consists of electrochemical cells with external connections for powering electrical devices eg mobile phones.



A non-removable battery is such that it cannot be removed from the phone except it is given to a qualified technician.

Mobile phone batteries have evolved over time. It may interest you to know that in 1946 when the first cell phone was used, the mobile battery uses was a car battery because the phones then were very big.Presently there has been huge improvements in cell phone batteries.Some constraints such as bulky batteries, batteries getting very hot, difficulty in disposing dead batteries, charging time have all been taken care of.

A non removable battery are mostly lithium-ion batteries, and it replaced the removable batteries seamlessly because it takes lesser space in the back panel thereby making the phone appear slimmer.The battery capacity of a non removable battery and the owners usage will determine how long it Will last.But we all know that batteries always get bad, and when it does get bad it is hard to remove it without tampering with the very important parts of the phone.Hence to remove the battery, it is advised that it is taken to a qualified technician who will use the appropriate tools to remove the battery and replace with a new one.

Depends on the battery. The 4000 mAh battery in my Blackberry Motion still lasts as long as it did when I bought it 3 years ago.

Depends on the battery capacity

No matter the capacity even if its 6000mah, ready for placement after 2 years
