Fairphone 5 fails in DxOMark battery analysis and dies after two hours of camera use

[Redaktion]

The straightforward replaceability of the 4200 mAh battery in the Fairphone 5 is certainly one of the highlights of the smartphone's features, but DxOMark's detailed analysis now reveals the disadvantages of this design.

The fairphonr is not a gaming device nor is it designed for extreme performance. It is a phone for people who just want something that works.

Should probably mention how much better for the planet the Fairphone is - because you wouldn't want people to take a first world problem (only 5 hours of gaming!) over a pressing global issue that effects us all in their decision making.. would you?

Racoons rule! Peace and love,

But you can simply pop the back cover and plug a spare battery, like in 2000s. So nothing of all this matters, it's just a reviewer's phantom pain of glued batteries and back covers.

Something that works... and goes on working, potentially to 2033 and at least 2031 with all important parts user-replaceable.

That's why it's "good for the planet" and leading the way in repairability and product lifetime.

I don't agree with these results.

I use a Fairphone5 as my daily phone. I often end the day with 30% battery remaining after medium usage (calls, emails, video streaming, sat nab).

Today I drive for 2.5 hours using Waze on battery power (no USB cable in car). When inejdednthe journey I had 75% battery remaining. My journey started at 3pm, so I'd already had 7 hours of on-battery time before starting the journey. So I reckon 15% battery usage on a 210minute journey using satnav. Admittedly it was dark and the sun set not long after departure, but nonetheless the GPS was running the entire time.

If I wanted to get more life out of my phone, I can always install LineageOS and not use Google Play Services, much like I did on my Fairphone 3, and if see battery time extend by around another 30%

It worth mentioning that the issue isn't the battery it is the CPU. To allow them offer 10 years of updates to the phone, they used a CPU that normally for industrial machines so the firmware/design of the CPU isn't designed to be power efficient at load because it was near a design concern when building the Chip as industrial machines tend to be power hungry anyway. They are work with snap dragon to even use this chip in the first place so hopefully a few firmware update are in the pipe line.
But it much better for the environment to keep supporting a CPU and phone or 10 years instead of two to five like we currently doing.
Fairphone has been fairly open about this, the fact your blame of the battery so a lack of basic research.
I had the fairphone 5 now about a month. I consider myself I high usage user and I only ever charged it at night and up to 80% (fairfair software because a battery protection mode to extend the life of your battery that does this) but I can for see days it need a top up, but I already have power banks and if I want to a replacement battery is cheap I just have to deal it out. That said I would love fair phone to offer a stand alone battery charge that be cool

How is any of what this article describes a "design" issue? It could be an issue with the specific components chosen for the FF5, but the implication is that the highly repairable nature of the device is somehow to blame.
