[German]Interesting finding on the subject of bulging batteries in Microsoft's surface tablets. Redmond has screwed on the firmware, so that the bloated/bluged batteries should be avoided. However, not all models get these firmware functions.
As an outside observer (I myself do not own a Surface device) I can state that Microsoft does not really have the Surface platform under control. There is a lot of tinkering going on. And yet there are always massive technical problems that drive Surface owners crazy. The current blog post is about battery problems.
The problem with bloated/bulged batteries
The battery problems with the interfaces are a permanent problem. Sometimes the batteries are discharged too fast and Microsoft tries to fix this by updating the firmware. Then suddenly rows of batteries die an early death (see my German blog post Microsoft Surface Pro 3: Fix gegen Akku-Tod kommt (möglicherweise) bald). The Surface Pro 4 devices also have a battery problem. I had blogged about it here in the blog (Are there Battery Problems with Surface Book 2 and Pro 5/6?). Shortly after the devices are out of warranty, the batteries of some of them inflate. In the best case, the display jumps off and the device is then broken. The location here shows photos of a detached display. There are also hits for other Surface models (here, here, here and here). The buyer of such a device is is left outside in the rain, because Microsoft does not react.
@surface there are many owners of surface products with battery bulging and screen damage and still @microsoft is refusing to admit that they have a list of surface items that should be officially recalled and batteries replaced for our own safety. pic.twitter.com/SN1lNvULNF

And then there was the tweet above on the subject. Microsoft Surfaces and batteries, it's like fire and water
Firmware update against dying battery: Only for new models
A few days ago, a blog reader posted this comment within my blog. In the battery report of the device he could observe that his device was always overcharged in the first weeks. After several firmware and UEFI updates in May and June 2017, the battery capacity decreased after each firmware update.
the keep changing the language at https://t.co/bR2DGAjEsP and include comments that seem a little contradictory about safety. It seems to be mostly SP4 and SB original owners that are afflicted. The hidden message is "your Surface will last 3 years and that is all we support". pic.twitter.com/sdEW1jxUma

Barb Bowman then got in touch via Twitter and pointed out new features described in this Microsoft document. This includes the features introduced by firmware: Battery Smart Charging, Battery Limit Mode and Battery Lifespan Saver. The latter feature is intended to protect batteries against overcharging and would explain the above mentioned observation that the Surface model constantly shows less capacity in the battery report. Barb Bowman then wrote on Twitter that the features are only available for the latest Surface models.
so MY take on this is that based on the expanding bulging batteries on SP4, SB, S3, etc. this new feature was added for the newest devices. But isn't there for previous devices. So the issue was obviously (to me anyway) recognized.

In other words: If you have an older surface, where the battery is bloated, you are loosing. Microsoft only helps buyers in the first 3 years after purchase if there are problems.
