Anyone else had this problem?

Phone dies when battery reaches about 5% (not 1%). Plug in the charger but it takes 10 minutes before you can switch phone back on again?

Maybe this is covered elsewhere but with all the dodgey battery posts about it is hard to find things.

Thanks.

That behaviour is quite normal.

Powers down with 5% left and then refuses to reboot until it feels like it? What century is this?

Okay phone just died for the evening at 5%. Fully charged 9 hours ago. FIASCO!

Happens to other batteries when they drop below minimum level required to sustain operating the phone,  even on my N8 on the rare occasions when I leave it for too long. So it's in the same century.

That's happened to me on radar and lumia although battery on radar lasts nearly a week with moderate use.

yeah! it's in the same century.

I can sort of get the logic of shutting down at 5% but only if it is to enable a quick reboot when plugged in, which does not happen.

Also this was not the case with other brands.  I brought the phone to Phones4U are they were horrified at instant zombification of the device and failure to reboot. 

Also you think this happens with laptops? Probably with low spec cheapo models but it would be unacceptable if it powered down (which they do at 5%) but not reboot for 10 minutes when plugged in.  

So thanks for your response but it is nonsense. Looks like you had a dodge N8 too.

The 5% indication is highly unreliable and varies greatly from the actual value. I've had my "dodgy" N8 run for over 4 hours with several calls and texts while showing 0% remaining battery, so I would not rely extensively on inbuilt diagnostics. In addition, current battery management platforms will simply not allow a device to start up until the battery has reached a certain minimum level of charge to ensure safe and proper operation. Maybe these settings in the Lumia are not ideal or you did have a dodgy handset. That does not make the general principle invalid.

A couple of posts above you have an example of another brand doing the same - it's also a  current handset, so maybe your previous experience with other brands is with less modern and up-to-date devices running less sophisticated battery management..

The general level of intelligence and competence of P4U personnel allows for them to be easily impressed by events of much lesser magnitude.

Laptops boot from AC power even without a battery, so it is irrelevant how empty the battery is, since the laptop does not use power from the battery if the AC is plugged in.

Thanks. Makes sense. But never had this problem with an Iphone or the replacement phone Probably does happen though.  

Regardless it sucks.

If it was only ten minutes I'd be happy, but I plugged mine in and it didn't boot at all, in fact 12 hours of charge later it was still sitting on the battery icon with red bar and had not charged a bit!

It appears that when it's run out completely, (which depends entirely on what the phone thinks is completely I turned mine off at 7%  remaining and left it off until I got home to charge it) the Lumia doesn't want to charge or power up.

It's almost like it's stuck in a cycle of low charge, the image of the battery low icon uses charge and the phone won't start until it gets charge so it just sits there in a perpetual state of not charging. Run it dead and it will fail to charge or start until you randomly fiddle with the buttons, connect and reconnect the charger, in fact it took connecting it to my laptop this time to start it.

The Lumia it seems has high battery usage probably due to 3G driver issues as it overheats in your pocket if not in range of a strong signal probably as it just remains on and searching. It hates being run out, which seeing as it chooses what percentage to run out at is almost impossible to avoid and it charges irregularly sometimes the charge lasts 18 hours sometimes it lasts 6.  As someone who has had Nokia's since the very first mobile phones came out this phone deeply dissapoints and has brought me to the stage of finally saying brand loyalty is no longer enough I am considering looking at alternatives once my contract on this current underperformer expires.

I told myself after a few Nokia problems with other models (which I lived with because I love Nokias)  that this was Nokia's last chance for me and at first I actually thought they had pulled the stops out and achieved something. A short period of ownership has sadly proven this not to be true. 

If a random charging battery with no longevity is the best we can hope for Nokia is about to lose market share, sad really
