N9 battery trouble?
 

Hi.
I had a problem with my battery this week, it happens only one time, during skiing (maybe due to cold weather, about -4°c?) when I tried to make a video. Red icon, and telling impossible to make a video due to low level batery. When I took my N9 out of the pocket, few hours after, to charge it, battery was ok again!!!
I used the phone with lower temperature (-15°C) without such trouble.
Any idea?

@cevenn
I have exactly the same experience - when skiing if I put the phone in outer pockets - battery goes to red, video can not be shot. SO now I keep it in inner(warmer) pockets close to the body.
N9 battery seems to be very easily affected by low temperatures. Unlike N900 and other phones.
You can have a look at this: http://www.macworld.co.uk/ipad-iphon...pe=allchandate
iPhone 4S and Nokia N9 are the worst cases according to this study.

Re: N9 battery trouble?
 

I guess this is a sensor problem , the battery life should not be affected even if the phone shows "low battery" .

Re: N9 battery trouble?
 

Happened to me too while skiing.
God damn finnish phone can't stand the weather.

Really lousy job Nokia, shame on you.

Re: N9 battery trouble?
 

Just change the battery.. oh wait... >.<

This is one of the main things that's stopping me of getting an N9.. :(
Also this type of problem has happened with me before on the N8-00 and the N900.. Just try to keep it a bit warm like how someone mentioned earlier.. :)

Re: N9 battery trouble?
 

Thanks all!
Strange trouble, it was in a warm place, in my snow jacket inner pouch, and I was able to make pictures within -15°C without trouble last week.
Maybe it only happens with video?:confused:

Re: N9 battery trouble?
 

No, happened to me with sports tracker, camera and any other use.
The battery just can't stand cold weather which is not good.

Re: N9 battery trouble?
 

Hello cevenn, i see that you live in France like me ;) Same problem here :( Look at the BatteryGraph of mine : suddenly at about 30% of charge, the battery goes down to exactly a value of 4% ( like as discribe in this thread http://talk.maemo.org/showthread.php?t=82128 ) and then come back to normal value after about 5 minutes. I think it's a software or sensor bug. It happened to me 3 time during 1 month of use without explication.

;)

I'm in Ardèche:
Last week I made pictures with -15°C, without any trouble:

Hi every one,

I had the same problem. In addition, I also had a problem of "Incorrect password" with all synchronizations. What I did? Reinstall my N9 OS (PR 1.1) via Nokia Sofware Update (NSU) using a Windows 7 PC (I'm an ubuntu user). For NSU to work with N9, you need also to install "Nokia Link". This will also help you to backup you phone. After reinstalling my N9, the phone is absolutelly fluide and the battery is OK (2 days in average for normal use). The password problem is also solved. :p

N9 is a great phone!

Re: N9 battery trouble?
 

Cold temperature makes the phone think the battery is empty. not a bug but true for every phone

Re: N9 battery trouble?
 

I think it is partly true. Electrons need to be able to move freely from one nucleus to the next to have a proper energy flow. They tend to "stick" more to their corresponding nuclei if they get colder. It shouldn't drop as seen in the pictures thou. Maybe its a feature to make the phone think its running on emergency supply only. To keep damage away from the phone as low temperature working conditions need special equipment that can cope with it?

Battery Test : Nokia N9
Vs. comparative smartphones

GSMArena did the battery tests on quite a few comparable smartphones, including the Galaxy Nexus. I refer below the most likeable five [5], which many compared/consideration while seeking the N9. It's amazing to see that our beloved MeeGo-Harmattan fared much better than the other [most] expected ones.

3G Talk Time:
How the battery went from 100% to 0% on talk time over a 3G network.

Web Browsing:
How a fully charged battery took time, while refreshing web pages with their automated script, to deplete its juice.

Video Playback:
How the smartphone/s used 90% of their battery (the trial ends there) after continuous video playback.
http://img832.imageshack.us/img832/9...tvideoplay.gif

Overall Score:
They conclude with the most important of their tests, the "overall usage". That number [in red] means that you will have to charge that smartphone every that many hours if you do one [1] hour each of browsing, video playback and 3G calls per day.

CONCLUSION:
Apple iPhone 4S works out to be the overall leader with 45 hrs. of Endurance Rating, while doing fairly well under most individual tests, sure some others beat it irregularly... however, our own Nokia N9 doesn't seem to much lag behind - scoring 39 hrs. of endurance, beat only by the SGSII at 40 hrs... which is incognito to me. While the Galaxy Nexus sure was a disaster at 35 hrs. faring nothing scholarly at the individual tests as well. Quite drab I'd say [though non-technically!]... while even our 'twin-sister' with WP7.5 Mango under the same shell fared better !

But, man-o-man! Did the Nokia N9 rock?
Second best [keeping the SGSII at par]! That sounds good... what with all the talk about 'idle consumption', 'older processor', 'poor battery life' and the likes? GSMArena suggests that reasonably heavy users should expect to get about a day and a half from their N9s. Good enough?

Ps.: I'm a non-techie... do not know the wherewithals... but my overall experience with my N9 has been astounding, vis-a-vis my iPhone4. And GSMArena seems to concur!

Re: N9 battery trouble?
 

Because I do not want to start another thread I will ask a question here(battery/charge related):
I notice on my N9 that the icon on low power standby screen when battery is fully charged comes in 2 flavors:
1. The mark(tick?) inside the battery icon is RED.
2. The mark(tick?) inside the battery icon is GREEN.

Anybody have experienced that? Anybody knows what colors mean? Case #1 happen more often, like 7 out of 10 charges.

PR 1.2 will fix that problem?

Re: N9 battery trouble?
 

Hmm, it's black and white, and depending on the position on screen and the screen itself, the tick appears to be green or red?

Re: N9 battery trouble?
 

but sgs2 battery is replaceable, :(
when our n9 batteries goes drop, how we can replace it? :confused:

Re: N9 battery trouble?
 

Yes, exactly - the tick itself appears red or green. The icon volume is white.

Re: N9 battery trouble?
 

A radical solution is just to reinstall your Nokia N9 software as I said in a previous post. Since I reinstall my phone, the battery life is really improved (more than 48h with normal use : calls, internet, 3G, wifi). Fluidity is also significantly improved.

Now I really love my N9. My opinion is that the UI of N9 is the best, the design is great. Shame that Nokia did not believe in this great phone.

Just one thing : the lack of applications on the store. But for me, I have most of what I need. The only application that I really miss is "deezer". So some times I use Galaxy Nexus just for that app. Galaxy nexus is a good phone but the truth is that I am now very frustrated by other UI: N9 UI is so natural! I often find myself tapping the galaxy nexus to wake him up, or sweep the screen to switch to another application.

Re: N9 battery trouble?
 

Need to make a backup first?

Re: N9 battery trouble?
 

It's replaceable, there's plenty of info. out there that explains how to do it.
It's not for technical neophytes though, you need to have some common sense.
It does seem to be easier than the iPhone4/4S, still not a "walk in the park".

Re: N9 battery trouble?
 

PR1.2 Follow up: After updating to PR1.2 I have charged my phone twice and every time I get the green tick inside battery icon. Don't know what this mean, but just different than PR1.1.
Follow up 2The tick just alternates between red and green depending on the position of icon on screen. Question answered :)

Re: N9 battery trouble?
 

Does green tick mean Power Saver mode is ON?

Re: N9 battery trouble?
 

@ceevee
You can't have power saver mode ON when device hooked on a charger.

Re: N9 battery trouble?
 

Partly true indeed - I do lithium battery research for a living. Chemical kinetics depend on temperature anyway (temperature is effectively a measure of how fast atoms are moving) but some of the commercial liquid electrolytes inside these batteries can start to freeze just below 0oC. I live in Canada and can say that ALL phones, cameras, etc with lithium-ion or lithium-polymer batteries cope poorly with very cold conditions - keep them in an inside pocket if you want to be sure they'll work properly. However, if they do freeze they'll be fine when they warm up again. Ni-Cd batteries do have some advantages....
