FULL N900 Talktime Test (3G Connection)!

| December 12, 2009 | 27 Replies

Hey all,

I’m sure a lot of you have seen Nokia’s N900 talk time test with the talking clock? if not its below.

I thought that I would do my own test as Nokia’s one is only really half a test (it’s assuming that if the battery is showing half left that it will last 2 times the time is has already lasted, which is usually rubbish so I thought I’d use some of my unused free minutes to do a test of my own!

Nokia’s Battery Test

How long does Nokia say the battery will last?

This was really hard to find, Nokia’s specifications don’t seem to include it (only say it has a 1320mAh battery) and even gsmarena.com have just left it blank! but after searching around I found a post on the official Maemo forum which claims the following:

Operating Times
Always online: Up to 2-4 days (TCP/IP connected)
Talk time: Up to 5hrs WCDMA, 9hrs GSM
Active online usage: Up to 1+ day

We’ll soon see if these are even close!

My Battery Test

To make is more about the actual talk time rather than anything else I have set the phone up as follows:

  • Internet connection completely switched off
  • Any active desktop items disabled (i.e. RSS, weather, Facebook, etc)
  • Network signal: 3G
  • Called a landline number so I know I am not going to run out of battery on the other end!
  • Nothing done on the phone except screenshots every hour or so or when there is a significant change
  • Battery Fully charged

    N900 fully charged

    N900 fully charged

  • Start test immediately after disconnecting the charger

    N900 Call started

    N900 Call started

Ok now the call has started, I kept checking back on the phone to see how long it would last and noticed that after 2 hours (like the Nokia video) the battery level was about half but about reaching the 4 hour mark people where expecting, lets just see!

N900 Battery life

N900 Battery life

Ok so as you can see the battery started dropping a bit quicker after 2 hours were up. At about 3 hours and 18 minutes, the “Battery Low” warning showed up for the first time and the level turned red so I knew it was on its last legs!!

It got to 3 hours and 30 minutes in and it was still going but then about 4 to 5 minutes later it switched off!

Note: I realised that I had a system monitor running which drains a lot of battery, so without that it should last a lot longer!

So if I factor in things like me constantly checking the phone to see the battery level, and taking screen shots, I think I could have squeezed about 5 or so more min out of it so I’d say talk time estimate to be about 3 hours and 40 minutes on 3G! (Much lower than the 5 hours I read on the Maemo forum)

If you run on 2G it should be about double this so around 7 hours 30 min to be optimistic! (Much lower than the 9 hours I read on the Maemo forum)

You have to note that in this test it is in best case scenario because if you have things going on in the back, i.e. texts, e-mails, etc the time will drop but at least now you know what you can stretch your N900 battery to!

    I’m sure you could get much more out of it if you removed the constant system monitor. I know it is used for screen shots but it has to be a huge drain on the battery.

    • http://www.mobilemainframe.co.uk llaadd

      I was not using a system monitor…i just took screen shots at certain times. when i wasn’t taking a screen shot I let the screen switch off to save battery as it would be if it were next to your face when your on a call.

      • rushey

        ok. just i’ve had the ‘load app’ installed myself but removed it as i was unable to stop the constant system monitor bars as seen below the telephone icon in your screen shots. It would be useful if that function could be disabled but i don’t know how.

        • http://www.mobilemainframe.co.uk llaadd

          ow that’s what you meant…sorry…half asleep!! Only way to disable/enable is to uninstall/reinstall it unfortunately.

    Just so you lot know, I will be doing a follow up test with a replacement high capacity battery I bought off ebay which claims to be 1930mAh (original nokia battery is 1320mAh) so theoretically I should be seeing a increase of about 40%! I’ll let you know how the new generic battery fairs probably next week or just after as I want it to settle, the first few day’s are never what the battery will always do!

  • No.

    Aftermarket batteries are usually rubbish. You’ll never get a 40% increase unless the tests are somehow twisted and biased.

    In my personal experience, having chosen aftermarkets carefully (for the likes of the N95 years ago) they may claim to have more mAh capacity, but in practice offer about the same or less talktime due to battery-cell quality as the original Nokias. I’d avoid.

    • http://www.mobilemainframe.co.uk llaadd

      well you are right, I knew I was taking a chance and it was about the same…either way I sent back for refund.

      • HumanPenguin

        Well that in itself would be an interesting blog post.

        A few people have looked at the same or similar battery. So far we have avoidede it due to fears of the thing exploding.

        Learning that its also no better tyhen a 1350 mah is very comforting.

        Also if your up for it. A review of some of the cheap external chargers woiuld be nice3. Most of them only seem to give out 350 mah unlike the Nokia charger at 1200 mah.

        Knowing how long they take to charge vs the talk time would be good.

    Which PR did you have when performing the test? What was the volume of the conversation?

    BTW: do you think using headset instead of using phone directly can improve or decrease talk time?

    • http://www.MobileMainframe.co.uk llaadd

      this one was when the phone first came out and I made a mistake by having a system monitor app loaded which was draining the battery more then normal so first off the talktime should be more then stated above. The firmware was either:

      OS 2009 version 1.2009.42-11
      OR
      OS 2009 version 2.2009.51-1

      On your second point, I’m not sure, but I don’t think it will increase talk time, most likely either make little to no difference, assuming you mean a wired headset, if your mean Bluetooth headset, it will definitely reduce talk time.
