Nokia Lumia 800 and the battery issue:
If you are active on twitter or read the blogs actively, then you sure would have listened about battery issues with Nokia Lumia 800 and must be thinking that what’s wrong this phone. So, let me tell you details about the issue.
There are two issues actually and both of them are software related, NOT hardware related.
First Issue is as described by Nokia itself, a software bug which is "limiting the phone’s ability to access the full battery capacity". According to Nokia, not all Lumia 800 phones are affected by this issue.
There is very easy way to check your unit. First, fully charge your battery and then dial ##634# to access the Service menu (Nokia Diagnostic app). Go to Battery Status section – if your capacity is less than 1000mAh then your Lumia 800 is indeed having a problem accessing the full battery capacity.
Obviously, nothing to worry as the fix is on the way (even delivered as an update for some) and even If you don’t want to wait though, Nokia will replace your phone with a brand new piece (only a small percent of Lumia 800 units are affected by the issue, obviously not the new ones).
Second issue is one that becomes visible when you fully discharge the phone, which obviously will happen with most of the people, who use the phone a lot. If you discharge the phone completely, and then attempt to re-charge, occasionally the phone will go into an endless boot loop, where it powers on, starts WP7, detects that the battery is below its power-off threshold, and shut down. Then the cycle repeats.
Actually what happens here is unlike most of the electronic devices out there, Windows Phone software on Nokia Lumia 800 somehow allowed to drain the battery completely rather than switching it off before 5% battery threshold reached (user will be shown that battery went 0%). And once it happens even charging wont work as that part too requires the device to have a little charge remained. I tried this overnight and couldn’t boot the device if placed on with normal charger.
The simple solution of the same issue is to charge by connecting the discharged phone to PC/Laptop via the provided USB cable, which charges the phone without the requirement of having the phone some battery backup remaining in it. Trust me, this will always works.
As about the issue, then yes it is an issue and Nokia\Microsoft are aware of it. An update is already rolled out to fix the software bug and the new update will be able to shutdown the phone when its on 5% battery capacity, hence eliminating the issue.
Conclusions and verdict from my side:
So, what I say about Nokia Lumia 800? Should one buy it or not? Is it worth the price or not? etc etc.
I don’t want to be diplomatic here, but will again say that it depends on individual’s choice and use cases.
If your purpose is Social Networks, Calls, Messages and wanna have a phone that may make people turn their heads towards you, then sure Nokia Lumia 800 has no match. The inherent simplicity of Windows Phone makes everything else out there feel outdated and the looks of Nokia Lumia 800 is sure the deal breaker.
Windows Phone as of now, feels complete for most of the things that you are used to do with your phone and that too without bothering for any details. Some (including geeks) might find it over-simplification of things and may feel that they have less options for customizations here, but remember same been the story for original iPhone too that was out even without many of the popular essentials and nothing stopped it from changing the world.
But this is about Windows Phone, when about Nokia Lumia 800 itself, then being the first Nokia Windows Phone, I would say that there are a few things that will hold my hands to recommend it fully. There are some big compromises that has been made to deliver it before time and the biggest compromise is front camera.
Microsoft has bought Skype and already laid out plans that first they will deliver a Skype for Windows Phone app soon and then the integration into the core by end of second half of the year itself. Sure, Nokia Lumia 800 feels itself out of the place, when Nokia Lumia 900 has already been announced with better specs (though no raised curved glasses like Lumia 800 anymore), so its your choice if you wanna wait for another few months or wanna enjoy the beauty.
So at the end, this time again, I will leave this over you only.
