My LG K5 or better probably the battery faced (or is still facing) a slow death while being on the travels. A look back on my only 10 months with that phone.
After four years with Samsung Galaxy S3 mini before this phone not even lasted one year. I can easily see, 'Of course, because it was free', but the issue is most likely related to the battery.
But from the beginning: As I got it seemed like a step forward for me on one side - since there was an Android 5 version installed from the beginning. But it had lots of downsides: The camera was worse than at the previous Samsung. And there was not even a proper music player pre-installed.
No chance of making a playlist or anything. I additionally added the Vanilla Music player for at least being able to let multiple run in a row.
And the phone storage was a big problem: I was always close on the space, even if I had put media files on a separate SD card - but I was really limited on the amounts of apps I could install.
It wasn't even possible to extend the app storage through an SD card. And then came the biggest issue: The battery.
First it was alright listening to music all day at work, but then it got rapidly less. I went to flight mode quite often to keep the battery alive. Especially WiFi and mobile data cost a lot of energy.
In March I reached a point where the battery went down to 0 within 15 minutes. I could only temporary start the phone again. And the charging process got weird: Sometimes it went quickly to 100% or it remained stuck at 0%. Often you need to put in on charger for an hour to be able to boot at all.
This situation confronted me with the situation: New battery for around AU$40 (if I find it) or switch to another phone.
And I find a good price for a Huawei Y7 the situation was easy to solve. Just migrating the data is a matter of patience. As the LINE backup went easily via bluetooth, WhatsApp needs to saved different as my current backup is not up-to-date and I also need to change the phone number since I cannot activate WhatsApp on new phone with a European number while being in Australia. Probably I will temporary switch...
Anyway, since the LG was free, it was alright. But now I already feel better using the new Huawei phone.
