High capacity battery for the N9
 

Hi,

Has anyone tried something like this?

Or any other capacity brands?
I believe that nowadays there aren't original ones, except unmounted from spare parts etc, so as I'm buying a new one, thought why not by one with a higher capacity

Re: High capaciry battery for the N9
 

There are lots of batteries that are advertised to have better capacity than the originals but most if not all are really bad quality, having at best the same capacity as the originals.
You just cannot tell without trying, I guess.

Aggreed. That's why I'm asking if anyone has some experience with any of them.
I once bought a laptop replacement accu that is advertised as higher capacity (pure Chinese btw) and indeed it is. But that guy already had some feedback on them, that made my choice easier.

Best,
Istvan

I've ordered one and I'll report back (if I don't forget ;) ) when I install it

Hi, I tried a 1800mAh* GiXa Dynamic, last year. It was not the first battery I changed in my N9 but previously I had only used original ones. I was disappointed at the beginning, as I found it lasted even a bit less than the originals. After one year, though, it does not suddenly go down from 30 to 4 % under heavy usage, which happened a lot with the original ones.

I got the battery today, and replaced it already. I'll report within a few days with the impressions.

Re: High capacity battery for the N9
 

What I suggest, to get some real data on power capacity use a cronjob that logs battery state every half-an-hour to a file.

Best of course to have such data from both batteries on the device, over many weeks of use.

Re: High capacity battery for the N9
 

Well I'm not keen on making such efforts hahaha.
What I can say is more human readable. The battery lasts over 3 days with moderate usage (phone, email push, skype online all the time, some sms and half uasble web).
I'm ok with it. If I remember correctly the original battery lasted around 2 days on similar regime, and about half a day while idle in the end,.
So anyway, it's a progress.

3 days with Skype always online?
Wifi or 3G, 2G?

Re: High capacity battery for the N9
 

Is it possible to get battery information (capacity, discharge rate in mW, etc) in Meego? There is no usual /proc/acpi/battery/ subfolder and I haven't found anything like "*attery*" in /proc/ /sys/ etc.

Re: High capacity battery for the N9
 

Try command "bmestat"

Re: High capacity battery for the N9
 

Thanks, exactly what I needed!
Well, I'd like to see capacity in Wh and usage in mW instead of converting Volts and Ampers but anyway its ok!

Re: High capacity battery for the N9
 

Yes. I depend on Skype a lot. It was mostly in wifi, except that 3g

Re: High capacity battery for the N9
 

Bought a couple of BV-4D 1320 mAh from France, bmestat reports:
battery max. capacity: 1200
battery cur. capacity: 1198

Are those fake chinese batteries or bmestat doesn't know about 1320 models?

Re: High capacity battery for the N9
 

AFAIK using bmestat you get a reliable capacity figure since that's what is reported by the battery itself.
It might be however more accurate after few charge/discharge cycles.

As for what is the real capacity and what's printed in the label of the battery; I find those figures usually differ a fair amount whatever the origin country of the battery :)

@pishta74, I am looking to order a replacement battery for my N9. After a few months of usage, are you still satisfied with your battery's performance?

And anyone else, do you have a good referral for a replacement battery?

Thanks in advance!

Re: High capacity battery for the N9
 

Mixed WiFi or 3.5g

Re: High capacity battery for the N9
 

Yeah it still works fine
