My battery would die out to fast. I was constantly charging my phone, and at times the battery life would say 30% then just shut off . Usually i would opt for just buying a new phone which i have done in the past, BUT since the phones are now pay full price or monthly fee of an extra $30 I decided i would just keep charging my phone all day.
My husband said look for a battery online, and i will switch the battery. I said can you do that ? He said i'll figure it out. SO i found ifixit.com and ordered the battery. The package arrived in 2 days so fast.
The repair went well the do it yourself Kit had everything we needed to replace the battery. The process took less than 30 minutes . There are videos online that help explain how to replace the battery. So far the battery life is working well. No complaints. I saved a lot of money this way.
My advise is order your parts and have someone repair at home instead of paying hundreds or even ordering a new phone that will die in less than 2 years anyhow.
