Dluong85, May 24, 2018 : Yes, another one of these posts. Hear me out. I used a OP One from 2014 to 2016. Great phone for $300, but I ran into that dreaded microphone issue. No amount of software tweaking fixed it, so I went to the ZTE Axon 7. It was within the same midrange budget as the OPO at $400 ($360 after discount). Primarily went with the A7 because of the screen and sound (stereo speakers are awesome for youtube and netflix); at the time, it too offered the best processor, the SD820. The camera was notably worse than the OPO, but I lived with it. After a year and a half of use though, the battery is now terrible. Two hours screen on time, and I have to recharge at least twice a day. I'd hoped to get at least two and a half, maybe three years of use out of this phone, but I'm considering going back to the OP6. Like the OPO and the A7, the biggest factor for me is budget. Here's a few options: 1) Get the OP6. On one hand, the specs are incredibly tempting. I'm ok with giving up stereo speakers in exchange for what seems to be a pretty great camera. On the other hand, regardless of how good the value is, I don't NEED to spend >$500 (realistically I'd get the 8gb/128gb option) 2) Replace the battery on the A7. $30 for the battery, maybe another $50 to take it somewhere for replacement (or attempt the replacement myself). If that restores battery life to something more respectable, I figure I can get another few years of use out of it. Thoughts?
