Better battery?

Anyone know of any compatible battery or plans for one that will last longer than the one that comes with the 95?

Sorry, no. Its been discussed many times on various AAS forums, and the consensus is that it is not economically possible to fit a genuinely more powerful battery into the same size of battery case. Avoid anything off eBay.

I just got myself a Proporta USB battery and carry that with me - its only slightly larger than a phone but it's probably good for 2 may be 3 charges.

What I've done to get round this problem, is bought a few items from l8shop.net:

1 x Twin Desktop Charger for the Nokia N95 @ �8.95 = �8.95
1 x Original Nokia CA-100 Charger Via USB Port @ �13.95 = �13.95

And I've also bought an original Nokia BL-5F battery (awaiting delivery) from eBay.

The twin desktop charger is a stand, that allows you to charge not only your phone, but also a second battery. As my computer is on most days, I bought the USB cable to plug into this stand, and that keeps both batteries on charge however you can also just plug a standard charger into the stand.

Just be careful charging up the second battery in that desk charger. It will not have a cut off circuit in it to stop charging the battery when it is full. Your spare battery will meet a grisley death quite soon unfortunately. 😞

I actually have one of the desktop chargers too with a spare battery. When i charge the spare battery the light changes red then green in around 2hours i think.
Would that suggest it has a fully charge cutoff?

No, I doubt it very much..... As soon as it turns green, I would remove the battery from the charger if I were you.

Wow that sucks, I wouldn't wanna spend two hours watching a little LED!

I thought genuine Nokia Li-On batteries had the overcharge protection circuit build in to the battery housing?

Bad news, it doesn't fit. The N73 use BP-6M and its similar in dimensions and contact arrangement to the N95's however its shorter and I think a tiny bit fatter.

I'm sure Nokia see the N95's battery life as an oversight. I see no reason why they couldn't have made it a higher capacity. I would like to think they'll release a better battery soon.

"Bugger!" .. still with reasonable power management I get through the day sometimes two .. but I have chargers at home, in the car and at work just in case.
😊

Could anyone explain to me where is this cut off circuit located,
inside battery, in mobile or in charger (power supplier)?

In answer to the question; I think most batteries have over charging protection built in, though Nokia do say in the manual not to leave the charger connected to the phone when the battery is fully charged as it can shorten the life of the battery.

I recently upgraded my phone to the N95 and I couldn�t believe how bad the battery was. I fully charged it on the evening I got the phone and in the afternoon of the following day it had dropped down to two bars and then switched off as I was leaving work. Someone I work with said he has a few friends with the N95 and all have the same problem. He said that one of them complained to Vodafone and they sent him an up rated battery. I have looked on the net but I can�t find any up rated batteries for it but I am with Vodafone so I will phone them and see what they say. He also said that he knows someone who works for O2 and they have taken them of the shelf because of it, not sure if that is true.

What I have done for the time being to make it last a bit longer is. I turned off the WLAN scanning; I turned off 3G as I am not on 3G and also turned off the GPS, as whenever you slide up the front to dial a phone number or to read / write a text it obviously starts to look for satellites. I can always turn it back on again if I need to use it. this has made a bit of difference.

One thing I have noticed with my N95 is once the power has dropped one bar it then starts to drop quite fast, is this common with the N95? An example to this is: I fully charged it last night when I got home from work (5.30ish) I didn�t really use the phone until this morning when I made a short phone call. I then didn�t use it again until about lunch time when I showed a friend a video clip, (approximately 8 mins long) and after that it had dropped one bar. By the time I left work it had dropped down to two bars without me using it. Is this typical of the N95?

I believed the design of Li-On batteries dicated they were Smart batteries which controlled the charge cut off themselves?

2 questions. 😉

1. How do you turn off the internal GPS receiver? (Or do you mean A-GPS?)

2. Are you sure GPS receiver starts every time you open the keypad?
I was under the impression that GPS chip only runs when a GPS app is launched and the software asks the N95 for a location fix. That's one reason there's always a time delay after launching the app before GPS locks onto the satellites.

1 day of average use is about all you can expect with the N95 battery. Pervious Nokia smartphones got about 1.5 - 2 days out of a charge. If it makes you feel better, one of my work colleagues has a windows CE smartphone and he can only get about 40 minutes use of TomTom on a fully charged battery whilst we can get around 3 hours.

The handset has 2 CPU's whereas every other Nokia Smartphone had only one which is probably part of the power drain. Your 8 minute Video would work the 2nd CPU hard as it's dedicated to Graphics.

I think the N95 uses a lot of current in standby mode (compared to non-smartphone handsets), so the battery would still go flat in 24 hours even if you never used the N95 even once after a full charge.

Does it mean that this desktop charger with a seperate place for a spare battery is safe to use, as each battery has its own built-in cut off circuit?

I am not sure about sliding up the front, I assumed that activated the GPS but I could be wrong but I have definately noticed a diffetrence in battery life since turning it off though.

To turn off the integrated GPS:- Menu > Tools > Settings > General > Posisioning > Positioning Methods. Here you can choose to activate / deactivate Bluetooth GPS, Integrated GPS and Network Based.

At the moment I have Integrated turned off and as I said I have noticed a slightly better battery life.😊

1. I really don't think the GPS starts looking for satellites when you open the slider. Why?
A. It would be silly to look for satellites just because you wanna type a sms or something like that. Nokia being European knows all about sms messages and of course takes this into considerations.
B. The GPS being located under the keypad doesn't mean a thing. You can still get a fix without opening the slider, it's just a bit faster with a clear view to the sky.

2. The GPS standby time on Microsoft devices really isn't that bad. I had a Mio A701 for a year and with the light turned fully on and the CPU at max speed of 512MHz, the battery lasted for 3 hours. Crank the light and CPU speed down and you have 6 hours of TomTom navigation. The N95 gives me a bit more than 5 hours of Route66 and changing the light output doesn't change much.

3. We did a lot of experimenting with turning the GPS on/off on the A701 forum and surprisingly, it didn't have a noticable impact on the standby time. Until someone does a real test on this on the N95, I expect it to be the same. By a real test I mean twice placing the N95 in the same physical spot and leaving it alone till the battery dies, once with the GPS turned off in Settings and once where it is on.

4. The cradle in posting #4 of this thread does have some electronics inside, so I assume it would be perfectly safe to use it for charging.

5. Don't waste your money on non-oem batteries. The manufacturers lie about the capacity. I have tested a few and they don't have much more than half the standby time of the original Nokia battery.

Hi,

I have found this thread on this forum,
and decided to buy such a charger:

http://www.datakits.co.uk/store/twin-desktop-charger-for-the-nokia-n95-p-3608.html?osCsid=4313bbf14f88bb0723ab4413a195f7bf

Today I received a parcel and I see a similar charger,
the place for spare battery matches perfectly, but there are only two metal contacts instead of three ones inside to charge a battery. The battery doesn't charge at all when it is put in this place. What's wrong? There is written on the package that it's a charger for N95, but maybe the content was mistaken?
Can anybody confirm that has such a charger with two or three electric contacts?

Thanks in advance

Sorry for rising a topic.

It turned out that the contacts in the charger does not fit very precisely to those ones in battery. I had to use a screwdriver to put metal plags of a charger into the contact holes in battery.

... "Made in China".
