Since the iPhone first launched in 2007, there’s been a steady increase of smartphones released with non removable batteries. Initially it isn’t a big problem, but there are a number of pitfalls in using non-removable battery smartphones vs removable battery smartphones.
1) Dead Brick Effect
When your battery dies, your phone also dies without a method to replace the empty battery with a fully charged unit. Imagine running out of battery in an emergency situation without the ability to call for help.
2) Expensive Battery Repair Service
Some manufacturers charge up to $79 for standard battery repair service after one year warranty whereas it costs you about $10 to $20 to replace your own removable battery. Considering Apple has sold more than 500 million iPhones since 2007, the potential battery repair market alone is worth 39.5 billion dollars!
Apple isn’t the only manufacturer with non-removable designs. With Sony, HTC, LG, Google Nexus, Huawei, and Nokia, the battery repair industry potential is much more than 39.5 billion dollars. Also, battery life issues typically don’t occur until after 400-500 charges (well beyond a year of constant use). Your smartphone battery will be out of warranty before you start to experience problems.
3) Removable Batteries Are 30-40% More Power Efficient Compared to External Batteries and Battery Cases
Because there are no removable batteries to replace for certain phones, you are forced to use an external battery charger or battery case. However there are major power inefficiency losses with external battery sources. A 3000mah external battery charger, for example, doesn’t mean it provides a full 3000mah charge to your smartphone. External battery chargers and battery cases require voltage conversion from 3.7v to 5v to charge your phone, and along with circuitry and USB cable energy transfer loss, your external battery typically loses 35-40% power due to inefficiency. This means you are only getting 1800-1950mAh of charge for a 3000mAh external battery. Removable batteries don’t have this inefficiency problem because they provide direct energy transfer to the phone.
4) Phone Freeze
Smartphones are mini computers. Just like computers they occasionally freeze. When a phone freezes up, the easiest way to unfreeze it is to reboot the phone by removing the battery. Some non-removable battery phones may have a hard reset option, but that can stop working during a big freeze and require your phone to entirely deplete its battery before you can reuse it.
What do you think? Should we have removable battery smartphones or not?
