Non-removable battery - good or bad?

[venom0706]

I just started using my brand new Xperia Z2 and plan to stick with it for at least a year and a half. However, I read some disturbing news that the battery might get faulty in less than a year (if I charge it every day) and I won't be able to change it, since it is non-removable. This news got me very disturbed for my phone, as I plan to charge it every day (I am a heavy user). Do you think the battery will last during that time? Thank you.

If you charge it when it gets down to 40%-50%, that's fine - it should last a few years. If you let it get down to 10% every day, it might not last out the summer. That's one reason for a replaceable battery - swap in a spare when the one in the phone gets down to 40%.

It is the worst when you want to keep the device for some time. The first thing that goes to hell is the battery. I guess it does not matter too much when you switch phones regularly (every 1 or 2 years).

Thanks for the replies! So, in my case it won't make much difference? Also, do I need to download an app that will prolong the battery life (the overall battery life inside the phone), although the phone has built-in options like Stamina, Ultra Stamina and Low Battery Power Saving modes? If yes, what is that app? Thank you.

Noone can tell you for sure. Normally batteries (even bad ones) should last at least one year. But if the hardware is really faulty, it can break within two days. You never know. I do not think that any app could change anything in such a situation.

I do not know where you are from and what laws you have there, but in Germany they are obligated to change (or repair) the device if it broke during the first two years.

Built-in batteries can theoretically have a slightly higher capacity, but I prefer removable myself: it's nice being able to replace the battery easily or use an extended battery. It's not a deal-breaker for me, though.

What if I charge it from 30% every day? Would that be ok? Also, do I have to give the phone specifically to a Sony service for a battery replacement and how much would that cost me? I noticed that my battery gets down really fast, even when on Stamina mode and that is only by surfing the Internet for 2-3 hours... It basically drops by 1% every 3-4 minutes when web browsing. Is that normal? When I have a 12 minute call, it barely drops by 1%, but when web browsing, another story...

My personal experience is somewhat related to what Rukbat said. My current Samsung Galaxy is charged daily but I'm a light user. After ~24 hours, the battery went from 100% to about 85%. That would be the point when I charged it (85%). It used to be at 90% for 24 hours standby. The reason for the drop? Once, and just once, I run some heavy apps till the phone shuts down. Since then, the battery for standby mode drops to 85% after 24 hours, instead of 90% like it used to. BTW, when that occured, the phone (and battery) was about 1.5 years old.

I've never had an issue with a Li-Ion battery and I always charge my phones every day. The only phone I've had since 2007 with a removable battery was the Galaxy Nexus.
