Most of the current mobile phones cannot change batteries.

Not the current mobile phone can not change the battery, but now the mainstream mobile phones are integrated high-integration smart phones. If the battery has problems or need to replace the battery, it is generally taken to the factory after the sale to the engineer to help you change, of course, it is necessary to spend Money. Unlike the modular design of the battery that was dismantled and replaced in the early years (Last year LG and MOTO also introduced modular phones, but still niche products, users are very few, so it is not in the scope of discussion). In addition, if you are a machine-made person and have a professional disassemble workbench and a complete set of tools, you can try to disassemble the phone to replace the battery. (Friendly reminder: you have broken the warranty is not guaranteed)

Second, the lithium battery of the smartphone is generally charged and discharged after 500 cycles, the actual capacity will be attenuated (the battery loss is intensified), that is, after you say that one year later, the original one-day mobile phone may take three times a day. The phenomenon that four charge can continue to be used. If you need more than four charge a day, it is strongly recommended to replace the original new battery after the official sale. Don't try to change the cards in the mobile phone repair shop. There will be double dangers of quality and safety. The original battery may have a safety hazard, not to mention the brand battery
